Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a cooler, particularly to one employing a two-step cooling technique of air cooling and water cooling for quickly cooling off high-temperature liquid or gas in a heat exchanger, having excellent effect of quick cooling.

2. Description of the Prior Art

A conventional cooler for lowering the temperature of high-temperature liquid or gas is provided inside with a cooling pipe with a water inlet at one end and a water outlet at the other end. The conventional cooler is further bored with an inlet and an outlet of high-temperature liquid. To cool off high-temperature liquid, it is conveyed into the cooler through the inlet to be cooled off by cooling water in the cooling pipe. After lowering temperature, the liquid will flow back to a main body of the cooler for use through the outlet, and then heated-up cooling water produced by heat exchange will be guided out of the water outlet. However, the conventional cooler carries out cooling only by water cooling, so it needs a comparatively large water tank and takes a comparatively long period to carry out cooling for lowering the temperature of the high-temperature liquid so as to enable the liquid to be used again. In addition, the heated-up cooling water is drained out through the water outlet and unable to be recycled for use, thus wasting resources.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The structure of a cooler in the present invention, as shown in FIGS. 1-5, includes a main body 1, a water tank 10, at least one air-cooling radiating device 11, at least one fan 12, at least one wind intake 13, at least one cooling pipe 14, at least one water-blocking device 15 and at least one water-cooling radiating device 16 as main components combined together.

A water tank 10 is disposed in a lower side of the main body 1 for storing cooling water and provided with at least one water pump 100 therein in connection with at least one water pipe 101. The at least one water pipe 101 extends upward and has its rear end formed with a spray pipe 102. The water tank 10 further has its one side bored with a water inlet 103 and an overflow outlet 104, its interior provided with a floating ball 105 for controlling the water level, and its bottom bored with a drain hole 106 plugged therein with a plunger 107.

The at least one air-cooling radiating device 11 disposed in the main body 1 is provided with a plurality of cooling fins 110.

The least one fan 12 is installed at an outer side of the main body 1.

The least one wind intake 13 disposed at a side of the main body 1 is each provided with at least one air filtration net 130.

The least one cooling pipe 14 is provided with an upper inlet 140 and a lower outlet 141 respectively disposed at both ends thereof, an upper bent portion passing through the plurality of cooling fins 110 of the at least one air-cooling radiating device 11, and a lower bent portion positioned near the lower outlet 141 and above the water tank 10.

The at least one water-blocking device 15 abutting one side of the at least one air-cooling radiating device 11 is provided with a plurality of sloping plates 150 formed therebetween with air-current passageways 151.

The at least one water-cooling radiating device 16 is disposed at another side of the at least one water-blocking device 15 and below the spray pipe 102. The at least one water-cooling radiating device 16 is provided with cooling material 160 and at least one drip-holding tray 161 positioned below the cooling material 160 and arranged with a plurality of water holes 162 for receiving water overflowing downward from the at least one water-cooling radiating device 16 and the at least one water-blocking device 15 and for providing further cooling function. The lower bent portion of the cooling pipe 14 is positioned below the drip-holding tray 161.

A first preferred embodiment of the cooler in the present invention, as shown in FIG. 1, is used to cool high-temperature gas, in which one air-cooling radiating device 11, one water-blocking device 15 and one water-cooling radiating device 16 are disposed in the main body 1; one fan 12 is installed at one side of the main body 1; one wind intake 13 is installed at another side of the main body 1; and one cooling pipe 14 disposed in the main body 1 has an upper bent portion passing through a plurality of cooling fins 110 of the air-cooling radiating device 11 and a lower bent portion wound below a drip-holding tray 161 of the water-cooling radiating device 16. The cooling pipe 14 further has an upper inlet 140 positioned near an upper end of the air-cooling radiating device 11 and a lower outlet 141 positioned below the lower bent portion of the cooling pipe 14. In using the first preferred embodiment, referring to FIG. 2, when the cooler is operated, the water pump 100 of the water tank 10 will pump cooling water to the spray pipe 102 through the water pipe 101, and synchronously the spray pipe 102 will spray the cooling water toward the water-cooling radiating device 16 and the cooling material 160, and the overflowing cooling water will flow downward to pass through the drip-holding tray 161 and get into the water tank 10. Meanwhile, the fan 12 is timely started to rotate and produce suction force to suck air into the main body 1 through the wind intake 13. After cooled by the cooling material 160, the air will become cool moisture and enter the air-cooling radiating device 11 through the air-current passageways 151 of the water-blocking device 15. When the high-temperature gas is conveyed into the cooling pipe 14 through the upper inlet 140, it will receive a first-step cooling by the cool moisture. After the high-temperature gas in the cooling pipe 14 is cooled, its density will become great and drop to the lower bent portion of the cooling pipe 14 to receive a second-step cooling by the cooling water dropping from the water-cooling radiating device 16.

A second preferred embodiment of the cooler in the present invention, as shown in FIG. 3, is used to cool high-temperature liquid, in which the structure is similar to that of the first preferred embodiment except that the upper inlet 140 of the cooling pipe 14 is positioned near a lower end of the air-cooling radiating device 11, and the lower outlet 141 of the cooling pipe 14 is positioned above the lower bent portion of the cooling pipe 14 and just under the drip-holding tray 161. In using the second preferred embodiment, when the high-temperature liquid is conveyed into the cooling pipe 14 through the upper inlet 140 of the cooling pipe 14, air is sucked into the main body 1 by the fan 12 and then passes through the cooling material 160 to become cool moisture. Then, the cool moisture enters the air-cooling radiating device 11 through the air-current passageways 151 of the water-blocking device 15 to make the high-temperature liquid received a first-step cooling by the cool moisture. And then, the high-temperature liquid will be conveyed to the lower bent portion of the cooling pipe 14 through the cooling pipe 14 to receive a second-step cooling by the cooling water dropping from the water-cooling radiating device 16.

A third preferred embodiment of the cooler in the present invention, as shown in FIG. 4, is used to cool high-temperature gas, in which two air-cooling radiating devices 11, two water-blocking devices 15 and two water-cooling radiating devices 16 are oppositely disposed in the main body 1; one fan 12 is installed on a top of the main body 1; two wind intakes 13 are respectively disposed at two sides of the main body 1; and one cooling pipe 14 disposed in the main body 1 has an upper bent portion passing through a plurality of cooling fins 110 of the two air-cooling radiating devices 11 and extending downward through a drip-holding tray 161 and has a lower bent portion wound below the drip-holding tray 161. The cooling pipe 14 further has an upper inlet 140 positioned near and between upper ends of the two air-cooling radiating devices 11 and has a lower outlet 141 positioned downwardly at a lower part of the lower bent portion of the cooling pipe 14, thus providing a cooler capable of cooling larger volume with more fastness. In using the third preferred embodiment, the high-temperature gas is conveyed into the cooling pipe 14 through the upper inlet 140 of the cooling pipe 14 for receiving a first-step cooling by cool moisture. After the high-temperature gas in the cooling pipe 14 is cooled, its density will become great and drop to the lower bent portion of the cooling pipe 14 to receive a second-step cooling by the cooling water dropping from the water-cooling radiating device 16. Thus, the high-temperature gas can be quickly converted into normal-temperature air to be recycled for use.

A fourth preferred embodiment of the cooler in the present invention, as shown in FIG. 5, is used to cool high-temperature liquid, in which the structure is similar to that of the third preferred embodiment except that the cooling pipe 14 having an upper inlet 140 positioned near and between lower ends of the two air-cooling radiating devices 11 and has a lower outlet 141 positioned upwardly at an upper part of the lower bent portion of the cooling pipe 14 and just under the drip-holding tray 161. In using the fourth preferred embodiment, the high-temperature liquid is conveyed into the cooling pipe 14 through the upper inlet 140 of the cooling pipe 14 for receiving a first-step cooling by cool moisture. And then, the high-temperature liquid will be conveyed to the lower bent portion of the cooling pipe 14 through the cooling pipe 14 to receive a second-step cooling by the cooling water dropping from the water-cooling radiating device 16. Thus, the high-temperature liquid can be quickly converted into normal-temperature liquid to be employed again.

As can be understood from the above description, this invention has the following advantages.

1. In the cooling system of this invention, the fan 12 is started to actuate air current as in an air-cooling heat exchanger for a first-step directly cooling by cold air; and the water pump 10 functions to actuate water to circulate as in a water heat exchanger for a second-step directly cooling by cooling water. By so designing, after carrying out the two-step cooling for heat exchange to lower temperature, the high temperature liquid or air coming into the cooling pipe can quickly be cooled off, having excellent effect of quick cooling.

2. Provided with heat exchangers for carrying out two-step cooling, the cooler of this invention has much better cooling effect than the conventional cooler that is provided with only one heat exchanger for carrying out one-step cooling.

3. The cooling heat exchanger of this invention is applicable to a hot and dry region and can be used for cooling high-temperature substances.

4. The cooler of this invention has excellent effect in refrigeration and air-conditioning, able to elevate cooling capability.

5. Different from a common water-cooled water tower, the cooler of this invention has high-temperature liquid and air circulating in the cooling pipe 14 without contacting with external air; therefore, cooling liquid and gas will not be polluted and produce no furring and impurities, able to maintain excellent cooling effect for long.

6. The cooling of this invention is simple in structure, economical in electricity and able to attain high-efficiency cooling effect. In addition, it is light, small, able to be freely moved about or placed indoors or outdoors, firm and durable, easy in maintenance, conforming to the environment conservation, and saving both energy and water.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
