Embodiment 1
[0026] Such as Figure 1 to Figure 7 As shown, a piston heat control device for a refrigerator compressor, the piston 1 is cylindrical, the piston 1 is connected to a crank 5 through a connecting rod 4, and the connecting rod 4 is connected to the connecting rod socket 8 of the piston 1 in rotation, The connecting rod socket 8 radially runs through the piston 1 , the length of the connecting rod 4 is greater than the diameter of the piston 1 , and the upper end of the connecting rod 4 is exposed outside the piston 1 . The piston 1 is slidingly connected in the piston hole 10 on the cylinder block 9 of the refrigerator compressor, and the cylinder block 9 of the refrigerator compressor is also provided with a connecting rod passing groove 15, so that the exposed part of the connecting rod 4 when the connecting rod 4 reciprocates with the piston 1 Can move in the connecting rod groove 15. The central area of the piston 1 is provided with a round crank connecting hole 16 for t...
Embodiment 2
[0029] The cooling fluid is water, the outer end of one flow hole is connected to a cooling water pump, the outer end of the other flow hole is connected to a recovery pool, and the recovery pool is connected to the cooling water pump through a water pipe. The heat insulating element 3 is bonded in the groove 2 . The heat insulating part 3 is injection molded with a plastic with a thermal conductivity of 0.04 W / mk. All the other are with embodiment 1.
Embodiment 3
[0031] The heat insulating element 3 is riveted in the groove 2 . The thermal insulation 3 is made of thermally sprayed Al2O3 ceramics with a thermal conductivity of 8.7W / mk. All the other are with embodiment 1.
