But water route.Power device IGBT and the laminating tight ness rating fitted of controller housing bottom surface and the smearing thickness of heat-conducting silicone grease are equal
There can be large effect to radiating effect.Power device IGBT heat build-up can be caused if radiating effect is bad.So that
Power device IGBT can not reach higher load factor, and the power device IGBT of same model can only operate in relatively low power
Grade, while power device IGBT works long hours will also result in bad influence in higher temperature to its life-span.
Utility model content：
It is small that technical problem to be solved in the utility model is to provide a kind of thermal resistance of cooling system, improves cooling effect
Electric machine controller water-cooling structure, the water-cooling structure of the electric machine controller enables power device IGBT to reach higher load
Rate.
Technical solution of the present utility model is to provide a kind of water-cooling structure of electric machine controller, including motor control
Water channel is provided with device housing and power device IGBT, power device IGBT, water channel one end is water inlet, and the water channel other end is water outlet
Mouthful, motor controller casing bottom is provided with mounting hole, and power device IGBT is fixed on motor controller casing bottom by fastener
Portion's inner surface, motor controller casing bottom is additionally provided with cooling water and enters water channel and cooling water water outlet, and cooling water enters water channel and cold
But water water outlet connects with power device IGBT water inlets and delivery port respectively positioned at one end of motor controller casing bottom inside
It is logical, cooling water enters water channel and cooling water water outlet be located at one end on the outside of motor controller casing respectively with external cooling water pipeline
Connection.
Using compared with prior art, the utility model has advantages below after above structure：Pass through said structure, cooling
Water will enter water channel by the cooling water on motor controller casing and be directly entered inside power device IGBT, and it is cooled down,
So that the thermal resistance of cooling system is greatly reduced, improve the cooling effect of cooling system so that power device IGBT can reach compared with
High load factor.
Preferably, the cooling water of motor controller casing bottom enters water channel and cooling water water outlet and power device IGBT
The junction of water inlet and delivery port is additionally provided with sealing ring, and cooling water enters water channel and cooling water water outlet is located at electric machine controller shell
Also convex enters water interface and cooling water water outlet provided with the cooling water being connected with external cooling water pipeline respectively for one end of external side
Interface.To ensure being effectively isolated between the cooling system of electric machine controller and electric machine controller inside, cooling water enters water interface
Conveniently it is connected with cooling water water outlet mouthpiece with external pipeline.
Preferably, motor controller casing bottom is provided with 6 mounting holes, power device IGBT is fixed by screws in electricity
Machine controller housing bottom inner surface.
Brief description of the drawings：
Fig. 1 is motor controller casing bottom surface structure schematic diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As illustrated in fig. 1 and 2, a kind of water-cooling structure of electric machine controller, including motor controller casing 6 and power device
Water channel is provided with IGBT5, power device IGBT5, water channel one end is water inlet, and the water channel other end is delivery port, electric machine controller
The bottom of housing 6 is provided with 6 mounting holes 1, and power device IGBT5 is screwed by screw is fixed on table in motor controller casing bottom
On face, the bottom of motor controller casing 6 is additionally provided with the cooling water coordinated with the water channel in power device IGBT and enters water channel 22 and cold
But water water outlet 21, cooling water enters water channel 22 and cooling water water outlet 21 is located at one end point of motor controller casing bottom inside
Do not connected with power device IGBT water inlets and delivery port, cooling water enters water channel 22 and cooling water water outlet 21 is located at motor control
One end of device hull outside is connected with external cooling water pipeline respectively.Preferably, the cooling water of motor controller casing bottom
The junction for entering water channel 22 and cooling water water outlet 21 and power device IGBT water inlets and delivery port is additionally provided with sealing ring 7, cold
But water enter one end that water channel 22 and cooling water water outlet 21 be located on the outside of motor controller casing also distinguish convex be provided with it is outer
The cooling water for connecing cooling water pipeline mating connection enters water interface 3 and cooling water water outlet mouthpiece 4, to ensure the cooling of electric machine controller
Being effectively isolated between system and electric machine controller inside, cooling water enters water and connect, 3 and cooling water water outlet mouthpiece 4 it is convenient with it is external
Pipeline is connected.
Said structure is crossed, cooling water will enter water channel by the cooling water on motor controller casing and be directly entered power device
