Device for enhancing heat dissipation performance of freezer compressor shell

Abstract

The invention discloses a device for enhancing the heat dissipation performance of a freezer compressor shell. The device comprises heat pipes and heat dissipation fins; the heat pipes are arranged on the top part and the side surface of the upper shell of a compressor, and are closely connected with the shell; the heat dissipation fins are embedded on the heat pipes, and are uniformly distributed on the top part of the upper shell of the compressor; one side of each heat pipe is semicircular, and the other side is flat, and clings to the upper shell of the compressor; the heat pipes are arch-shaped; the multiple heat pipes are arranged at intervals; the middle part of each heat pipe is arranged on the top end of the upper shell of the compressor, and two ends of each pipe cling to the cylindrical cover-shaped periphery of the upper shell of the compressor from the top end; the distance between every two adjacent fins is 5mm; the lower end of each heat dissipation fin is arc-shaped; the upper end of each heat dissipation fin is linear; the sharp corners of each heat dissipation fin are rounded; and multiple round holes which are regularly arrayed are formed in each heat dissipation fin. According to the device, two phase change heat transfer cycles of each heat pipe share the same condensation end; working mediums at two sides absorb heat from hot ends to be evaporated, and encounter and are mixed in the middle part of each heat pipe, so that strong turbulent convection heat exchange is formed, and the heat dissipation effect is enhanced.
