The mounting block 200 is fixed to the other end surface of the circuit board body 101, and the protrusion 201 is fixed to the inner wall of the compressor controller housing 100. Through the designed mounting mechanism, the circuit board body 101 can be conveniently installed in the compressor controller housing 100 during use, without the need to use traditional screws to fix it.

[0023] The working principle and use process of this utility model:

[0024] When the utility model is in use, the side plate 205 is first pulled to the right, driving the insertion rod 213, the limiting rod 207 and the concave block 210 to move. At this time, the concave block 210 slides on the limiting strip 209, and the insertion rod 213 slides in the moving groove 203. At this time, the spring 206 begins to compress under the squeezing effect of the mounting plate 208, and stops moving when it moves to a suitable position. Then, the circuit board body 101 is placed in a suitable position in the compressor controller housing 100, so that one end of the insertion rod 213 is aligned with the socket. 202 is aligned, one side of the plug plate 211 is aligned with the circular plate 212, and then the circuit board body 101 is moved to the right, so that one side of the plug plate 211 penetrates into the inside of the circular plate 212, and then the side plate 205 is released, and the spring 206 begins to reset, pushing the side plate 205 to move to the left, and then the side plate 205 drives one end of the plug rod 213 to penetrate into the inside of the socket 202, and the circuit board body 101 can be installed. When the circuit board body 101 needs to be removed, the above-mentioned reverse principle can be used;

[0025] When the circuit board body 101 becomes hot and generates heat during use, the heat will be absorbed by the heat-conducting vertical bars 301 and the heat-conducting horizontal bars 303 , and then transferred to the heat sink 300 . The heat sink 300 dissipates the heat to the outside of the compressor controller housing 100 , thereby dissipating the heat of the circuit board body 101 .

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
