The invention relates to the technical field of heat dissipaters, and discloses a microminiature cooling system of semi-closed type electronic equipment based on compression refrigeration. The microminiature cooling system specifically comprises a compression refrigeration system and an inner enclosure frame, wherein the compression refrigeration system comprises a compressor, a condenser, a capillary and an evaporator which are connected in sequence through connection pipelines; an air dryer barrel, a backflow fan, an evaporator and an electronic element to be cooled are arranged in the inner enclosure frame; the air dryer barrel is filled with an air dryer; the backflow fan is connected with the evaporator and is used for conveying heated air flowing through the electronic element to be cooled into the evaporator again; the inner enclosure frame is a closed type space; and closed air in the inner enclosure frame performs circulation flow in the shape of a Chinese character hui. By repeated circulating flow and refrigeration and dehumidification functions of the evaporator as well as adsorption of the air dryer barrel, the risk of condensed water on the electronic equipment in the closed space is avoided.
Description
technical field [0001] The invention relates to heat dissipation technology for electronic equipment, in particular to a semi-closed electronic equipment miniature cooling system based on compression refrigeration, which can ensure that the short circuit risk of electronic equipment will not be caused by water vapor condensation in an internal low temperature environment. Background technique [0002] Existing heat dissipation technologies for electronic equipment, such as forced air cooling and liquid forced cooling, all use the ambient air as the final heat sink. When used in harsh high-temperature environments such as plateaus, Gobi, deserts, and islands, the ambient air temperature is high, and the electronic components Heat dissipation becomes a problem. [0003] Compression refrigeration can provide a cooling medium lower than the ambient temperature, which can better cool electronic equipment and components. In existing technologies such as CN201010545934.5, electron...
