[0035] When using the motor drive board with an efficient temperature control structure, firstly, the support plate 1 is horizontally installed at the corresponding position, and a docking groove 4 is opened on the inner wall of the support plate 1, and the size of the docking groove 4 is consistent with the size of the positioning block 3 on the lower surface of the driving plate body 2, so the positioning block 3 on the lower surface of the driving plate body 2 can be snapped into the docking groove 4, so that the driving plate body 2 and the support plate 1 are docked and installed, ensuring the firmness of the driving plate body 2 when in use;

[0036] Embodiment 2:

[0037] In this embodiment, when the temperature of the driving plate body 2 reaches a certain value, the thermal bimetal strip 8 can be bent to open the micro switch 9. Figure 2 and Figure 6 As shown:

[0038] A support plate 6 and a fixing block 7 are arranged on the inner side of the mounting groove 5, and an adjustment structure is arranged between the support plate 6 and the fixing block 7, which can automatically perform a cooling operation according to the temperature change.
