In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
As shown in Figure 2-5, it is the structure diagram for the embodiment that the utility model radiator structure is applied to water pump all-in-one machine,
The radiator structure can radiate for the motor 21 in water pump all-in-one machine and drive module 22 at the same time, and above-mentioned drive module 22 can be to become
The driver such as frequency device or servo.Radiator structure in the present embodiment includes cooling passage 241, inlet and liquid outlet, above-mentioned
Inlet and liquid outlet are connected with cooling passage 241 respectively, wherein：Cooling passage 241 is located at 211 He of stator of motor 21
Between drive module 22, and drive module 22 is attached to the outer surface of cooling passage 241, the stator 211 of motor 21 attaches
In the inner surface of cooling passage 241.
Above-mentioned inlet can access coolant (such as pure water, ethylene glycol etc.), and coolant flows through cooling passage 241 and band
Walk the stator 211 of motor 21 and drive module 22 works caused heat, and from liquid outlet outflow by stator 211 and driving mould
Coolant after the heating of block 22.
Since liquid-cooling heat radiation efficiency is higher than wind-cooling heat dissipating efficiency, and above-mentioned radiation processes are independently of the worked of motor 21
