An intake port 22 and an exhaust port 23 are formed at a wall of the housing 11. The air inlet 22 is used for air inlet. The air outlet 23 is used for exhausting air. A heat sink 21 is disposed in the installation space below the power supply 12 for dissipating heat from the heat generating device in the control module 13. In this embodiment, the device generating heat seriously in the control module 13 is an on-off device, such as a mos transistor, a relay, or a triode. The on-off device in this embodiment is a mos tube. A fan 24 is installed in the installation space and disposed at the power supply 12 and the heat sink 21, respectively, for dissipating heat from the power supply 12 and the heat sink 21. The duct cover 25 has a rear end surface and a wall extending perpendicularly from the rear end surface to form a duct, corresponding to the peripheral space of the power supply 12 and the heat sink 21. The air duct cover plate 25 is fastened at the installation space and is fixedly connected with the shell 11. The air duct is matched with the arrangement and the wind direction of the fan 24, so that efficient heat dissipation is achieved.

Wherein, Ta-ambient temperature, DEG C;

p- -overall power loss, W;

q- -wind channel air volume, CFM;

t- -temperature inside the housing.
