Abstract
The utility model relates to a cooling device of a drive motor and a frequency conversion speed governor in an electric car; a circulating channel is arranged in the drive motor and the frequency conversion speed regulator in an electric car, and the inlet and the outlet of the circulating channel are communicated with the inlet and the outlet of a heat-dissipation water tank by a circulating pipe, and the pipeline of the circulating pipe is also communicated with a circulating pump. The cooling fluid of the water tank is drawn out by the electric circulating pump and directly enters the channel of the drive motor and the frequency conversion speed governor; the cooling fluid circulates in the drive motor and the frequency conversion speed regulator and brings out the heat, then returns the pipeline and reenters the water tank; an electric cooling blower can be arranged outside the heat-dissipation water tank and the cooling can be further carried out by the blower outside the water tank.
Description
Technical field: the utility model relates to the electrocar drive motors of the hydronic structure of a kind of usefulness and the device of the cooling that variable-frequency governor carries out.
Background technology: the cooling means majority of the drive motors of present existing electrocar and variable-frequency governor comes to host driven motor and variable-frequency governor heat radiation in air-cooled and natural air cooled mode, so fundamentally do not reach real cooling effect, the service behaviour of motor and variable-frequency governor is descended, influence output of car load power and mileages of continuation.
Summary of the invention:
The purpose of this practical full mold is to solve electrocar drive motors and variable-frequency governor cooling problem, and a kind of drive motors and variable-frequency governor cooling device of electrocar special use is provided.
Electrocar drive motors of the present utility model and variable-frequency governor cooling device, it is characterized in that: electrocar drive motors and variable-frequency governor have the circulation water channel, the import and export of circulation water channel are imported and exported with cooling water tank by circulating water pipe and are communicated with, and the pipeline of circulating water pipe also is communicated with circulating water pump.The utility model is so just to have realized: the circulation water channel is arranged in electrocar drive motors and the variable-frequency governor, by electronic circulating water pump the extraction of the cooling fluid in the water tank is directly entered drive motors and variable-frequency governor water channel, cooling fluid is taken heat out of after motor and variable-frequency governor circulation, is entering water tank from water return pipeline.The cooling water tank outside can have electronic cooling blower, and further the blower fan by the water tank outside cools off.Cooling water tank can also have another group to be imported and exported, and imports and exports with subsidiary water tank to be communicated with, and subsidiary water tank is as secondary water tank.When heat reaches one regularly, cooling fluid flows to secondary water tank from another pipeline of water tank when preventing that heat from rising, cooling fluid in the secondary water tank makes eventually and remains on the normal water level, the pressure that when circulating water pump is worked, produces, enter secondary water tank by water pipe, the loam cake of secondary water tank has the air circular hole, and the pressure of Chan Shenging discharges from circular hole like this.
The present invention compared with the prior art owing to adopt such scheme, the cooling means of drive motors and variable-frequency governor by an electronic circulating water pump with can solve with air-cooled cooling water tank.This system is installed together known water tank, water pipe, radiator, electronic circulating water pump, has guaranteed and the heat sinking function of existing fuel oil car, makes the performance of electrocar reach optimization.Structure and method for designing are simple and practical.
Description of drawings: accompanying drawing has been represented a kind of electrocar drive motors of the present utility model and variable-frequency governor cooling device structural representation, Fig. 1 is electrocar drive motors of the present utility model and variable-frequency governor cooling device equipment configuration figure, and Fig. 2 is the schematic flow sheet of electrocar drive motors of the present utility model and the variable-frequency governor cooling device cooling fluid and the type of cooling.Example below in conjunction with accompanying drawing further specifies the utility model.
Specific embodiment: this electrocar drive motors and variable-frequency governor cooling device, form by the circulation line of the drive motors of electrocar, variable-frequency governor, cooling water tank, secondary water tank, circulating water pump, connection.The drive motors of electrocar and variable-frequency governor shell have the circulation water channel, and the import and export of circulation water channel are imported and exported with cooling water tank by circulating water pipe and are communicated with, and circulating water pipe also is communicated with circulating water pump.
Among the figure: 1, drive motors 2, variable-frequency governor 3, secondary water tank 4, cooling fluid water return pipeline 5, electrodynamic type circulating water pump 6, cooling water tank 7, electronic cooling blower 8, electronic circulating pump discharge pipe road 9, secondary radiator drain kind 10, cooling water tank protect solar or lunar halo 14, each pipeline clip to secondary water tank water return pipeline 11, cooling water tank outlet pipeline 12, drive motors suspension ring 13, blower fan
At first referring to Fig. 1: join with the other end outlet pipeline (8) of electronic circulating water pump again after motor cycle water pump (5) cooling water tank (6) connects by outlet pipeline (11) among the figure, connect to become with drive motors (1) variable-frequency governor (2) again and enter pipeline.The outlet pipeline of drive motors (1), variable-frequency governor (2) is connected to cooling water tank by water return pipeline (4).Dispel the heat by electronic cooling blower (7).When level pressure was too high, the cooling fluid in the cooling water tank (6) was entered in the secondary water tank (3) by return pipe (10) pipe.Air and cooling fluid be interior the discharge from loop pipe to secondary water tank (3), and secondary water tank (3) flow in the cooling water tank by outlet pipeline (9) when the cooling fluid in the cooling water tank was not enough.
Referring again to Fig. 2: for the working method of the clearer and more definite whole cooling system of understanding, the spy provides a cooling fluid schematic flow sheet among the figure.(1) is motor for driving among the figure, (2) be variable-frequency governor, (3) be secondary water tank, (4) are the water return pipeline of variable-frequency governor and drive motors, and (5) are electronic circulating water pump, (6) be cooling water tank, (7) be electronic cooling blower, (8) are electronic circulating pump discharge pipe road, and (9) are secondary radiator drain road, (10) be the cooling water tank water return pipeline, (11) are the cooling water tank outlet pipeline.By this cooling means, can really make electrocar drive motors and variable-frequency governor reach the optimized type of cooling by electronic circulating water pump.
Claims (3)
1, a kind of electrocar drive motors and variable-frequency governor cooling device, it is characterized in that: electrocar drive motors and variable-frequency governor have the circulation water channel, the import and export of circulation water channel are imported and exported with cooling water tank by circulating water pipe and are communicated with, and circulating water pipe also is communicated with circulating water pump.
2, as said electrocar drive motors of claim 1 and variable-frequency governor cooling device, it is characterized in that: the cooling water tank outside has electronic cooling blower.
3, as said electrocar drive motors of claim 1 and variable-frequency governor cooling device, it is characterized in that: cooling water tank has other one group of import and export and is communicated with the import and export of subsidiary water tank.
