Description

Automobile electronic water pump motor housing

Technical Field

The utility model relates to an automotive electronics water pump field, concretely relates to automotive electronics water pump motor housing.

Background

With the increasing importance of the nation on energy conservation and emission reduction of vehicles, various automobile factories adopt a turbocharging mode to improve power or adopt a hybrid power and pure electric driving mode to achieve the purposes of energy conservation and environmental protection aiming at the traditional engine. At present, traditional mechanical water pumps are mostly adopted in a cooling system of an automobile, however, along with the development of new energy automobiles and the increase of the supporting force of the state on the new energy automobiles, more and more pure electric automobiles are put into the market, heat dissipation of electronic power devices and motors needs to be cooled, the traditional mechanical water pumps are not conveniently used in the pure electric automobiles, and a plurality of new energy automobiles adopt the electronic water pumps as water circulation, cooling or on-automobile water supply systems. The electronic water pump adopts a piezoelectric material as a power device, and electronization is thoroughly realized from control to driving so as to completely control liquid transmission by an electronic integrated system, thereby realizing adjustability and accuracy of liquid transmission. Compared with the traditional mechanical water pump of the cooling system of the automobile engine, the mechanical water pump can only provide flow according to the rotating speed, and the control of the water pump is not flexible enough; the electronic water pump is easier to control and longer in service life, so that the automobile electronic water pump is widely applied and has good market prospect.

Fig. 1 shows a conventional magnetic electronic water pump for an automobile, where 1 ' is a motor, 2 ' is a magnetic driving assembly, 3 ' is a magnet shaft, 4 ' is an impeller, 5 ' is a volute, the volute is provided with a water inlet and a water outlet, the motor drives the impeller to rotate through the magnet shaft in the magnetic driving assembly, as shown in fig. 2, a housing schematic diagram for mounting the motor in fig. 1 is shown, in order to facilitate heat dissipation of the motor in the existing market, it is considered to add a heat sink or a heat dissipating blade on the outer surface of the housing, so as to increase the heat dissipating area to accelerate the heat dissipation, however, adding a heat sink or a heat dissipating blade on the outer surface of the housing would cause the external interface of the motor to be limited under a large circumstance, and the structural design of the motor interface cannot be flexibly performed, and in addition, the motor housing is not beautiful.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem mentioned above, the application provides an automotive electronics water pump motor case, under the condition that keeps motor case good heat dispersion, has made things convenient for the design of external interface on the motor case.

In order to achieve the above technical effects, the utility model discloses a concrete technical scheme as follows:

the utility model provides an automobile electronic water pump motor housing, its inner space is used for installing the motor, its characterized in that includes shell body, radiating groove, the one end of shell body is stretched out and is had the motor output shaft, the internal surface range of shell body has a plurality of radiating grooves.

Further, the heat dissipation grooves are recessed on the inner surface of the housing body at equal intervals in the axial direction.

According to the above technical scheme, compared with the prior art, the utility model, the positive effect that its produced is: in order to give priority to the design of the external interface of the motor shell, the heat dissipation grooves on the outer surface of the motor shell in the prior art are transferred to the interior of the motor shell, so that the heat of the coil and the driving plate in the interior of the motor can be rapidly transferred to the motor shell, and the temperature resistance of the motor is further maintained.
