Abstract
The invention relates to a motor controller cooling structure of a hybrid electric vehicle. The motor controller of the vehicle is cooled in a water-cooling mode. A water jacket is fixed at the bottom of the motor controller, bolt holes are respectively arranged at two lateral surfaces of the water jacket, and the water jacket is fixed on a bracket of a vehicle body through bolts. A cooling water channel is arranged in the water jacket, the cooling water channel is positioned at the bottom of a heat radiating module in the motor controller, the cooling water channel is fixedly sealed by using a cover plate through bolts, a water inlet and a water outlet are arranged at the side edge of the cooling water channel, and the external part of the cooling water channel is connected with a water pump and a condenser in series to form a water-cooled passage. In the invention, the space in an engine compartment is reasonably used for skillfully designing the structure of the water jacket and the structure of the internal water channel and arranging a water inlet pipe and a water outlet pipe, and the motor controller can be integrally installed and positioned simply and conveniently. The water pump is started and stoped in real time by the temperature feedback of the controller to perform good heat radiating effect and reduce power consumption, thereby obtaining good effect.
Description
Technical field
The invention belongs to electric machine controller radiating mode technical field, be specifically related to a kind of structure and operation scheme of cooling system.
Background technology
Mix the electrical automobile electric machine controller at present and adopt air cooling way mostly, heat-sinking capability is lower, and indivedual water-cooling pattern, the comfort feature of its structure, mounting arrangements remains to be improved.Along with the development of severe hybrid power automotive technology, the electromechanical integration of high integration requires electric machine controller to be arranged in the machinery space.And higher ambient temperature is had higher requirement to the heat-sinking capability of controller in the machinery space, and simultaneously, the limitation in machinery space space needs that radiating effect is good, delicate structure, electric machine controller easy for installation.
Summary of the invention
The objective of the invention is at the electric machine controller that is positioned at hybrid vehicle engine hatch, solve the heat dissipation problem of controller, and the design-calculated water-cooled motor controller of hybrid electric vehicle, its water jacket is reasonable in design, delicate structure, easy for installation, and control water pump in good time and open, stop, play better heat radiating effect.
Technical scheme of the present invention is as follows:
A kind of water-cooled motor controller of hybrid electric vehicle, described electric machine controller adopt water-cooling pattern to cool off; It is characterized in that:
The fixing water jacket in the bottom of described electric machine controller, the two sides of water jacket have bolt hole respectively, on the support that is bolted to car body; In described water jacket, be furnished with Coolant gallery, the position of Coolant gallery is in the bottom of electric machine controller internal heat dissipating module, fix sealing by cover plate with the mode of bolt on the Coolant gallery, side at described Coolant gallery is provided with water inlet and water outlet, outside serial connection water pump and condenser device constitute water-cooled path.Described Coolant gallery is " M " shape.
The temperature of the CAN communication acquisition controller by entire car controller, when temperature reaches going up in limited time of predefined electric machine controller, the inner transistor turns of electric machine controller, relay closes, pump working, the water route conducting that is used to cool off; When described temperature reached the lowest temperature that sets, described controller turn-offed internal transistor, and relay disconnects, and water pump quits work, and the water route that is used to cool off is closed, i.e. cooling is interrupted, and so work is carried out in circulation.
The invention has the advantages that:
(1) installing and locating of this water cooled controller makes full use of space layout in the machinery space, adopts to be bolted on the support, and mounting tools is simple, and is easy to operate; Inlet tube and outlet tube is installed simple, and outside water route is simple, and it is smooth and easy mobile to be beneficial to refrigerant fluid.
(2) this water cooled controller inside " M " type water channel deft design, the water channel cover plate seals by bolt, and easy accessibility helps the investigation and the maintenance of water channel fault.
(3) the ingenious temperature feedback of having utilized controller of this water cooled controller, by CAN communication signal, water pump relay, heat radiation and energy-conservation effect have been played in the opening and closing of in good time control water pump.

The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
Referring to Fig. 1, electric machine controller is 1, water jacket 2 is fixed on electric machine controller 1 bottom, the two sides of water jacket 2 have bolt hole 3 respectively, and on the support that is bolted to car body, this kind bolted connection convenient fixing is also saved the space, front end face at water jacket 2 is furnished with inlet tube and outlet tube 4, be connected in series a water pump 8 and a condenser 9 respectively, constitute water-cooled on-cycle path, referring to Fig. 3.
Referring to Fig. 2, the internal water channel 6 of water jacket 2 is " M " shape, is arranged in the back side of the power model IGBT of electric machine controller 1, and cover plate 5 is fixed and is sealed in above the water channel by bolt 7.This kind design easy accessibility is beneficial to faults such as investigation water route obstruction.
Referring to Fig. 4, the control principle brief introduction of pump working: on the ambient temperature of setting electric machine controller/lower limit, electric machine controller is from the temperature feedback is arranged in the CAN communication, when feedback temperature reaches this value, electric machine controller is with an inner transistor turns, relay closes, water pump is started working, the water route conducting; When feedback temperature reached lower limit, electric machine controller turn-offed internal transistor, and relay disconnects, this moment the water pump interruption of work, the water route stops to flow.Like this, controller is realized the double effects of heat radiation in time and energy savings by the automatic open and close water pump of temperature detection of self.
