Compressor cooling type fully sealed high-efficiency radiating electronic cabinet

Abstract

The invention relates to radiating technology applied to fully sealed electronic cabinets, in particular to a radiating method and a radiating device applied to high power electronic equipment required to be fully sealed in outdoor severe environment. By adopting a Carnot refrigeration cycle principle, a low temperature and low pressure liquid cooling medium enters a cold plate radiator (also called internal heat exchanger) arranged in a sealed cabinet through a sealed pipe, absorbs heat generated when calorific electronic elements arranged on the cold plate radiator work, and is evaporated into low temperature and low pressure superheated steam; the low temperature and low pressure superheated steam passes through a liquid-vapor separator, and dried superheated gas is sent into a compressor, and compressed into high temperature and high pressure gas; the high temperature and high pressure gas is sent into a condenser to release heat, and is condensed into supercooled liquid; the supercooled liquid is subjected to pressure reduction by resistance of capillarity tubes into low temperature and low pressure two-phase fluid; and the fluid passes through a filter and a pipe, and is sent into the cold plate radiator, and the heat of the fluid is absorbed by the cold plate radiator to realize circulation, wherein an electronic mainframe adopts a fully sealed cabinet structure so as to achieve the waterproof, dampproof, dustproof and electromagnetic shielding aims. The device adopting the radiating technology has the advantages of high power, small volume, easy control of temperature, low noise, low cost, high heat exchange efficiency and the like.

Description

technical field [0001] The invention relates to a heat dissipation technology and a heat dissipation device for a chassis used in fully enclosed electronic equipment, in particular to a waterproof, moisture-proof, dustproof, and electromagnetic shielding chassis for high-power electronic equipment in outdoor or other harsh environments. A heat dissipation method and a heat dissipation device using the method. Background technique: [0002] With the rapid development of digital TV, mobile communication and other markets and technologies, more and more users pay attention to electronic equipment working outdoors or in other harsh environments, such as medium and low power transmitters, transponders, base stations, repeaters Wait. Working outdoors can be closer to the required coverage area, which reduces the power demand of the equipment, does not need to build a computer room, greatly reduces the cost of networking, reduces electromagnetic pollution, saves energy, and is con...

AI Technical Summary

Problems solved by technology

This heat dissipation method has great limitations. One is that it is bulky and heavy; the other is that the power is small. For example, a digital TV transponder adopts a cast aluminum chassis with an external size of 600mm*420mm*210mm and a 22Kg output power of 20W. When the ambient temperature is 25°C, the maximum temperature at the shell fins has reached 45°C
