Radiating, drive circuit board 2 can be fitted be fixedly connected with the inwall of shell body 3.
Shell body 3 is made up of heat-conducting, preferably, shell body 3 is aluminum, can guarantee that the structural strength of shell body 3, together
When ensure heat dispersion.In the present embodiment, shell body 3 is the cube shape connected into by five heat-conducting plates, and its one side is open to be formed
One openend.Shell body 3 is formed in one simultaneously, to ensure its sealing property and its heat conductivility.With openend on shell body 3
Relative heat-conducting plate is the blind end of shell body 3, the parallel inner surface for being fixed on the heat-conducting plate of drive circuit board 2 so that driving
The parallel inner surface for being fixed on the blind end of shell body 3 of circuit board 2, openend of the drive circuit board 2 away from shell body 3, further
Ensure drive circuit board 2 and extraneous isolation.Here, as other embodiment, drive circuit board 2 is also securable to outer
The inner surface of other heat-conducting plates of housing 3.
The fluid sealant 30 for being used for being sealed in drive circuit board 2 in shell body 3 is filled with shell body 3, fluid sealant is utilized
30 fill up space in shell body 3, drive circuit board 2 is embedded in fluid sealant 30, so as to which drive circuit board 2 is sealed outside
In housing 3, it is ensured that the water resistance of drive circuit board 2, while drive circuit board 2 can be firmly fixed in shell body 3.This
In embodiment, fluid sealant 30 uses silica gel, its water insoluble and any solvent, nonpoisonous and tasteless, and chemical property is stable, can be effective
Ensure the water resistance in shell body 3.Drive circuit board 2 and shell body 3 are formed into an entirety using fluid sealant 30, are one
Module, is easy to carry out integral replacing maintenance to it.In other implementations, also can be close using polyurethane sealant or silicone
Sealing etc. is used as fluid sealant.Herein, also drive circuit board 2 can be sealed in shell body 3 by other means, for example, driving
After circuit board 2 is fixed in shell body 3, install a closure and shell body 3 openend be tightly connected, or, shell body 3 by
