The shell 10 is provided with a groove, and the shape and size of the groove cross-section match the shape and size of the slider 6 cross-section. This makes the slider 6 form several channels between the heat conduction cover 8 and the shell 10 to facilitate the flow of the heat conduction medium, thereby increasing the path length of the heat conduction medium and improving the heat conduction efficiency.

[0031] When using this utility model, the heat-conducting cover 8 and the guide block 1 are assembled. Then, the cooling medium is delivered into the device through the first air inlet 2. The cooling medium passes through the first air inlet 2 and enters the first air outlet 7. Then, it passes through the first air outlet 7 and enters the cavity formed between the device and the housing 10, thereby cooling the heating mechanism 9. Due to the obstruction of the slider 6, the cooling medium moves to the left end until it enters the other side of the cavity through the gap between the slider 6 and the heat-conducting cover 8 at the leftmost end of the device. Then, it enters the second air outlet 4 on the guide block 1 through the second air inlet 5 and is discharged, thus completing the cooling of the power device inside the heat-conducting cover 8.
