Embodiment
Figure 2 shows that the structural representation according to motor-drive pump one preferred embodiment of the present invention.As shown in Figure 2, Headlamps of the present invention or glass for vehicle window washing unit motor-drive pump 10, head light washing system motor-drive pump 10 comprises housing 400, and is located at the motor 100 in the motor containing room 101 (with reference to figure 3) in housing 400.Meanwhile, in typical motor-drive pump 10, in housing 400, be also provided with seal ring 200, blade 300.Composition graphs 2,3 known, the output shaft (being positioned at the axle of motor-drive pump 10 lower end) of motor-drive pump 10 is connected with blade 300, and seal ring 200 is located between motor 100 and blade 300, thus realizes sealing to motor 100.The working principle of typical case's motor-drive pump 10 is: be with moving vane 300 to rotate when motor-drive pump 10 works, and to be sucked by the water in outer tank discharged by water outlet 402 by centrifugal action by the water intake 401 on housing 400.It should be noted that, the motor-drive pump comprising motor 100, seal ring 200, blade 300 and housing 400 belongs to the one routine setting of related domain, not specific to the present invention, only illustrates as a typical electronic pump structure at this.
As can be known from Fig. 3, be provided with motor containing room 101 in housing 400, for holding motor 100, and owing to accelerating heat radiation when motor 100 works, the side of motor containing room 101 has a vent 1011.In addition, motor-drive pump 10 also comprises the heat dissipation channel 500 be located between housing 400 and motor containing room 101, heat dissipation channel and vent, and 111 fluids connect, thus the hot air in motor containing room 101, enter in heat dissipation channel 500 via vent 1011.And with prior art as shown in Figure 1 unlike, the application's heat dissipation channel not for being located at the direction (in FIG for laterally) being parallel to horizontal plane.This is because present inventor finds, such motor-drive pump 10 that is arranged on when quitting work thus cause motor containing room 101 to be in negative pressure, is easy to the impurity such as the dust in external environment condition, steam are inhaled in motor containing room 101.Therefore in order to improve the sealing of motor containing room 101 better, the direction that the exhaust port 5011 of the heat dissipation channel 500 of the application is arranged be from vent 1011, along gravitational direction or and gravitational direction between be the direction of acute angle.Such setting, can effectively avoid the dust in external environment condition, steam etc. to be inhaled in motor containing room 101.And generally speaking, the passage that the heat dissipation channel 500 along gravitational direction setting compares cross setting is longer, heat diffusion area is larger, is conducive to heat radiation.In conjunction with the sealing of motor-drive pump and the consideration of thermal diffusivity, preferably, in this application, the gap of heat dissipation channel is 1mm-5mm, and the distance between exhaust port and vent is at least 1/2 of shell length (length along on gravitational direction).
And preferably, as shown in Figure 2,3.The heat dissipation channel 500 of the application's motor-drive pump 10, jointly can be limited by the inner side surface of housing 400 and the outer side surface of motor containing room 101 simply and form.More specifically, in embodiment shown in Fig. 2,3, housing 400 and motor containing room 101 are cylindrical, the part outer peripheral surface of housing 400 and the part inner peripheral surface of motor containing room 101 define heat dissipation channel 500 jointly, and all the other circumferential surfacies of housing 400 and motor containing room 101 are housing and motor containing room shared in common.Such setting, simplifies the structure of motor-drive pump 10 inside, is beneficial to heat radiation, and installs also very convenient.Certainly, those skilled in the art also can gently intelligiblely be, this specified structure is only a preferable examples, according to above pointed " direction that the exhaust port 5011 of the heat dissipation channel 500 of the application is arranged be from vent 1011; along gravitational direction or and gravitational direction between be the direction of acute angle " this design principle, those skilled in the art freely can design the motor-drive pump of other structures, and it can reach the effect providing pump seal equally well.
Meanwhile, preferably, known with reference to figure 3, motor containing room 101 and motor 100 are Spielpassung.Spielpassung herein refers to that the external diameter of motor 100 is less than the internal diameter of motor containing room 101.That is, operationally, motor containing room 101 seldom can apply pressure to motor 100.External diameter herein, internal diameter all refer to mean value.Such setting, can play the convenient effect of installing and accelerating heat radiation simultaneously.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
