Technical field

The present invention relates to electric machine controller, in particular to a kind of electric machine controller modular water air-cooled structure.

Background technique

Current common electric machine controller modular water air-cooled structure form is controller housing and water-cooling system is integral type.It is a Sorrow of separation condition individually welds together IGBT in water channel, only one intake-outlet.The shortcomings that prior art, has:

1) common electric machine controller water channel and shell are integral type, and every kind of controller and channel structure are unique, every exploitations New a controller out, channel structure can all have similar adjustment, re-mold, cost is caused to get higher.

2) project newly developed, product need to be redesigned and be verified, and increase the design cycle.

If 3) commonly use controller water channel to occur deforming or bulge, entire controller need to be replaced all, without maintenanceability.

4) common controller water channel integral structure or water channel and integrated modular structure, are all controlled just for a certain kind Device processed is applicable in, and substitutability is low.

The present invention proposes that modularization water channel has intake-outlet on five faces, can pick out at random one or more Inlet and outlet waters Mouthful, remaining intake-outlet is sealed by screw, is completed entire water channel connection, is suitable for different structure controller.

Specific embodiment

As shown in Figure 1, electric machine controller modular water air-cooled structure of the invention, including IGBT module 1, sealing screw 2, water Connector 3, modular water cold plate 4 and sealing ring 5；The IGBT module 1 is locked or is welded using screw, and module is fixedly installed in Change the contact of 4 surface of water-cooled plate to radiate, then modular water cold plate 4 is connected and fixed with motor controller casing.

As shown in Figure 2,3,5 water inlets 11~15 being connected to internal water channel cavity are arranged in 4 one end of modular water cold plate, 5 water outlets 21~25 being connected to internal water channel cavity are arranged in the other end；5 water inlets and 5 water outlets are located at mould 4 front, rear, top, and bottom of block water-cooled plate and endface position., can be convenient according to installation and design in carrying out actual installation process, appoint Meaning selects one or more inlet and outlet attaching water swivels 3, remaining water-in and water-out from 5 water inlets and 5 water outlets Mouth is sealed by sealing ring 5 and sealing screw 2, realizes water-cooled plate water inlet, cavity, the connection of water outlet water route.

Coolant liquid connects any one or more imports of water inlet 11~15 by water swivel 3, remaining water inlet passes through sealing Screw 2, sealing ring 5 are sealed.It enters back into water-cooled plate cavity and carries out heat exchange, take away IGBT module heat, pass through water outlet 21~25 any one or more outlet outflows, remaining water outlet are sealed by sealing screw 2, sealing ring 5.By this Modular water cold plate structure realizes water channel circulation and anti-leak function, and is effectively radiated to system.

For different capacity, different structure electric machine controller, modular water cold plate all can be selected, the water-cooled plate of selection is not required to Water channel design and analysis of heat transmission are carried out again, and shortening is designed and developed and the experimental verification period.

It is illustrated in figure 4 modular water cold plate internal view, a kind of water channel circulating form is expressed in figure, liquid cooling source passes through Left side water swivel 3 flows into 4 cavity of modular water cold plate into inlet 13, flows out from liquid outlet 23.Inlet 11,12, 14,15 and liquid outlet 21,22,24,25 blocked by sealing screw 2, sealing ring 5.

It is illustrated in figure 5 the modular water cold plate internal view of another water channel circulating form, liquid cooling source passes through feed liquor Mouth 15, flows into 4 cavity of water-cooled plate, flows out from liquid outlet 22.Remaining inlet and outlet can be blocked by sealing screw 2.Actual conditions There are many variants for water channel circulation, are not listed one by one.
