Description

TECHNICAL FIELD

[0001] The utility model relates to motor heat dissipation technical field, concretely relates to a water cooling structure of motor for vehicle. BACKGROUND

[0002] In the field of automobile industry, the motor for vehicle is one of the key components of the automobile power system, and its stability and reliability directly affect the overall performance and safety of the automobile. With the continuous development of automobile technology, the power density of the motor for vehicle is continuously improved, which means that a large amount of heat will be generated during the operation of the motor. If these heat cannot be effectively dissipated in time, it will lead to high temperature of the motor, and further affect the performance and life of the motor, and even cause safety accidents in serious cases.

[0003] The existing water cooling structure of the motor for vehicle still has certain deficiencies in terms of heat dissipation efficiency and flexibility. For example, under some working conditions, the existing water cooling structure cannot adjust the heat dissipation strategy in time according to the actual heat generation of the motor, resulting in low heat dissipation efficiency and failing to meet the heat dissipation demand of the motor well.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0021] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will now be described in detail with reference to the accompanying drawings:

[0024] Structural components:

[0025] The water-cooled structure for the vehicle motor in this embodiment mainly includes a motor body 2 and a water-cooled outer shell 1 fitted over the motor body 2. The water-cooled outer shell 1 is a hollow structure, with a first water-cooling pipe 4 and a second water-cooling pipe 5 installed inside. The inlet end of the first water-cooling pipe 4 is connected to an inlet pipe 14 for introducing circulating water; the outlet end of the first water-cooling pipe 4 is connected to a two-position three-way reversing valve 8. The first outlet of the two-position three-way reversing valve 8 is connected to the inlet end of the second water-cooling pipe 5 through a connecting pipe 13. An inlet branch pipe 6 is provided between the inlet pipe 14 and the connecting pipe 13, and a valve (in this embodiment, the valve is a solenoid valve 7) is installed on the inlet branch pipe 6. The outlet end of the second water-cooling pipe 5 is connected to an outlet pipe 10, and an outlet branch pipe 9 is provided between the second outlet of the two-position three-way reversing valve 8 and the outlet pipe 10. A first temperature sensor 11 is installed inside the water outlet pipe 10 to monitor the water outlet temperature in real time; a second temperature sensor 12 is arranged on the inner wall of the water-cooled housing 1 to monitor the temperature inside the water-cooled housing 1; and a mounting base 3 is installed on the water-cooled housing 1.

[0026] Normal operating conditions:

[0027] Under normal operating conditions, circulating water enters the first water-cooling pipe 4 from the inlet pipe 14. Because the water-cooling pipe has a spiral structure, this structure increases the flow path and residence time of the circulating water within the pipe, thereby improving heat dissipation. After absorbing heat generated by the motor body 2 in the first water-cooling pipe 4, the circulating water enters the second water-cooling pipe 5 through the first outlet of the two-position three-way reversing valve 8 and the connecting pipe 13, continuing to absorb heat, and finally flows out from the outlet pipe 10. At this time, the solenoid valve 7 on the inlet branch pipe 6 is in the closed state, and the outlet branch pipe 9 does not participate in the circulation.

[0028] Improving heat dissipation efficiency in operating conditions:

[0029] When the first temperature sensor 11 detects that the water temperature in the outlet pipe 10 is too high, or the second temperature sensor 12 detects that the temperature inside the water-cooled housing 1 is too high, it indicates that the motor is generating too much heat and the heat dissipation efficiency needs to be improved. At this time, the control system will regulate the two-position three-way reversing valve 8 and the solenoid valve 7. The two-position three-way reversing valve 8 switches to a state that connects the outlet of the first water-cooling pipe 4 with the outlet branch pipe 9, and at the same time opens the solenoid valve 7 on the inlet branch pipe 6. In this way, part of the circulating water enters the second water-cooling pipe 5 directly from the inlet pipe 14 through the inlet branch pipe 6, and the other part enters the first water-cooling pipe 4 from the inlet pipe 14 and then flows directly to the outlet pipe 10 through the outlet branch pipe 9, so that the first water-cooling pipe 4 and the second water-cooling pipe 5 form a parallel connection. In the parallel state, the circulating water can carry away the heat generated by the motor more quickly, thereby improving the heat dissipation efficiency and achieving a better water cooling effect.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
