Miniature refrigerating device for computer chip radiation

A micro-refrigerator for the heat radiation of computer chip, which is characterized in that: a compressor is connected with a condenser, the condenser is connected with a capillary and an evaporator via a drying filter, the evaporator is connected with a compressor via a separatory barrel to form a refrigerating loop; the evaporator is a single-stage or multi-stage type on the pipe connected between the drying filter and the separatory barrel in parallel/series or hybrid mode, the capillary is connected on the pipe in the front of each evaporator; the compressor can be a steam compression refrigerator, an absorption type refrigerator, a steam jet type refrigerator, a compressed air refrigerator, an eddy refrigerator or a Stirling refrigerator, a Vuilleumier refrigerating or a GM refrigerator, etc. The refrigerating capacity is 10-2000W, with the input power 10-400W; based on the mechanical refrigerating principle, the utility model adopts the active cooling for a plurality of heating elements in the computer, and is applicable for the upgrading of computer. The whole system has small volume, low energy consumption, high temperature drop, high reliability, and easy operation.
