Cooling energy saving structure
A cooling energy saving structure, capable of connecting to a PCB multi-axial driller, includes a chiller, a freezing dryer, and a thermal superconductive recycling device, where the chiller has a liquid outward piping and a liquid inward piping, the freezing dryer has a gas outward piping and a gas inward piping, and the thermal superconductive recycling device accommodates the liquid inward piping of the chiller and the gas outward piping of the dryer. The device further features cooling the liquid in the inward piping before it flows back to the chiller, and heating the gas in the outward piping before it is discharged. The heat exchange performed between the flow back liquid of the chiller and the discharged gas of the dryer takes advantage of the device, which proves to have substantially cut down energy consumption and power expenditure for a very effective use of energy resources.

2. Description of the Prior Art
During the drilling process on a printed circuit board (PCB), a demand for manufacturing environment calls for a precise control over temperature, humidity, and dust-free and free of disturbance by chemical substances. How on earth does the above demand meet? The answer is to separate factory buildings sufficiently from the outside world to form a closed space, followed by linking the closed space to an air-conditioning system that breathes in unceasingly outdoor fresh air, cools it down, and pipes it into the closed space to keep a constant temperature for a driller during its sustained running with circuit boards. The PCB multi-axial driller is operated in a 24-hours unceasing mode with both its motor and rotary axis running in a rotation rate above 250,000 rpm. The drilling operation calls for chiller and freezing dryer to ceaselessly offer liquid and gas that are the operational requirements and an operation for the drop of temperature, to ensure the speed and quality of the process. However, the maintenance of indoor temperature, and the energy consumption by the chiller and the freezing dryer will certainly lift costs of utilities and production. Moreover, the spreading of poison gases (CO2 etc.) emitted by the equipment has already seriously endangered the ecological balance of surroundings. Therefore, how to amply and efficiently exercise the energy resources have already become tremendous themes of research for those devoted in that industry.
Conventional PCB multi-axial drillers have a cooling structure as shown in
However, the cooling structure of the conventional PCB multi-axial drillers still has drawbacks as follows:
Firstly, reducing the temperature of cooling water to 16˜20° C. by the 3RT chiller 10a, not only consumes energies, but also spreads exhaust heat in the air-conditioning rooms which will overload the operation of the air conditioner.
Secondly, the 3RT chiller 10a is used as a means to perform heat exchange for the cooling water, and capillaries related to its coolant are controlled in a state of minute operation over a long period of time while the compressor are lacking of controlling over load reduction, which results in the freezing efficiency of the chiller much worse than the expected, and the on and off operations of the compressor further raises power consumption.
Thirdly, the chiller 10a, the freezing dryer 20a, and the PCB driller 5a are set to expose in the air-conditioning rooms and the exhaust heat out of these equipment further overload the air conditioner and power consumption.
Fourthly, during the standby for the rotary axis 52a of the driller 5a, the freezing dryer 20a still provides unceasingly low-temperature compressed air which causes the temperature of rotary axis 52a too low that in turn yields troubles of condensing into dewing and dripping.
Fifthly, the freezing circulation device of the chiller 10a and the freezing dryer 20a make use of coolants as R22 or R134a in its internal piping as the cooling source that brings about grave damage to ecological environment and the ozone layer.
Accordingly, the inventor recognizes the foregoing problems, aiming at proposing the present invention which is a feasible design with an effective improvement upon those problems based on the strength of his long years of industry experience and research.
SUMMARY OF THE INVENTIONThe present invention is to provide a cooling energy saving structure to perform heat exchange between inward liquid of a chiller and outward gas of a freezing dryer through the use of a thermal superconductive device, which can substantially lower energy consumption and electricity expenditure for a very effective use of energy.
To fulfill the foregoing purposes, the present invention provides a cooling energy saving structure, capable of connecting to a PCB multi-axial driller, where the structure comprises:
a chiller, which has a liquid outward piping and a liquid inward piping;
a freezing dryer, which is located in one side of the chiller, where the freezing dryer has a gas outward piping and a gas inward piping; and
a thermal superconductive recycling device, which accommodates the liquid inward piping of the chiller and the gas outward piping of the freezing dryer, then cools the liquid in the liquid inward piping before it flows back to the chiller, and heats the gas in the outward gas piping before it is discharged, to accomplish the desired goal.
