HEAT DISSIPATION DEVICE
A heat dissipation device includes a housing internally divided by a partition plate into an upper and a lower space; at least one heat pipe bank having a condensing section and a vaporizing section located above and below the partition plate, respectively; and a blower fan assembly located in the housing corresponding to the vaporizing section. The housing has a first air inlet and a first air outlet located above the partition plate, and outdoor air entering into the housing via the first air inlet to flow through and exchange heat with the condensing section before exiting the housing via the first air outlet; and a second air inlet and a second air outlet located below the partition plate, and indoor air entering into the housing via the second air inlet to flow through and exchange heat with the vaporizing section before exiting the housing via the second air outlet.
The disclosure relates to a heat dissipation device, and more particularly to a heat dissipation device having at least one heat pipe bank to enable increased heat dissipation effect.
BACKGROUNDThere is a plurality of electronic elements arranged in a telecommunication control chassis or cabinet, an electric control box or cabinet, an optic fiber exchange chassis or cabinet, a machine room, a control panel, or a machine room for digital electronics. These electronic elements and other related facilities produce a large amount of heat in the chassis, the cabinet, the machine room or the control panel during operation of the electronic elements and the related facilities. The produced heat must be dissipated into outdoor air with the help of some heat dissipation devices, so that the chassis, the cabinet, the machine room or the control panel and the electronic elements therein can be maintained at low temperature and good cleanness to keep working efficiently. For instance, a telecommunication chassis designed for use by telecommunication companies is a closed box to maintain a required cleanness therein. An air conditioning and cooling system is then provided to cool the heat produced by the electronic elements and other related facilities in the telecommunication chassis or to carry the produced heat to an environment outside the telecommunication chassis, so that the electronic elements and other related facilities can have a required low temperature to operate normally. However, the air conditioning and cooling system will consume a large quantity of energy. Please refer to
To protect the chassis and cabinets for electric and other telecommunication devices against a very hot, salty, or other severe environment, the chassis and cabinets must be fully closed to be weather-resistant. Therefore, an air conditioning machine is used to cool down the environmental temperature inside the telecommunication chassis. The air conditioning machine has the disadvantage of high power consumption. During summer time, it is particularly difficult to dissipate the heat produced by the electronic elements and other related facilities and accumulated in the telecommunication chassis, which will have adverse influences on the reliability of the electronic elements and the related facilities.
SUMMARYTo overcome the problems in the conventional heat dissipating systems for chassis and/or cabinets for different electric devices, such as telecommunication control chassis and cabinets, an aspect of the embodiment provides a heat dissipation device, which includes a housing being internally divided by a partition plate into an upper and a lower space; at least one heat pipe bank having a condensing section and a vaporizing section located above and below the partition plate, respectively; and a blower fan assembly located in the housing corresponding to the vaporizing section. The housing has a first air inlet and a first air outlet located above the partition plate, and a second air inlet and a second air outlet located below the partition plate. Outdoor air can enter into the housing via the first air inlet to flow through and exchange heat with the condensing section and then exits the housing via the first air outlet to form an outdoor-air circulating path; and indoor air can enter into the housing via the second air inlet to flow through and exchange heat with the vaporizing section and then exits the housing via the second air outlet to form an indoor-air circulating path.
Another aspect of the embodiment provides a machine room with a heat dissipation device. The machine room is enclosed by walls and is internally provided with electronic elements or telecommunication facilities. The heat dissipation device is mounted inside the machine room on a wall thereof, and includes a housing internally divided by a partition plate into an upper space and a lower space and having first air inlet and outlet located above the partition plate as well as second air inlet and outlet located below the partition plate; at least one heat pipe bank arranged in the housing and having a condensing section and a vaporizing section located above and below the partition plate, respectively; and a blower fan assembly arranged in the housing corresponding to the vaporizing section. The first air inlet and outlet are located corresponding to the condensing section, while the second air inlet and outlet are located corresponding to the vaporizing section.
The structure and the technical means adopted by the embodiment to achieve the above and other objects can be best understood by referring to the following detailed description of the embodiments and the accompanying drawings, wherein
The embodiment will now be described with some embodiments thereof. For the purpose of easy to understand, elements that are the same in the embodiments are denoted by the same reference numerals.
