Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a high-heat dissipation new energy motor. Background Art

[0002] New energy motors are used to be installed on new energy vehicles, and the vehicles are driven by motors. Compared with ordinary motors, they can save energy and reduce long-term operating costs. New energy motors usually use permanent magnet synchronous motors or AC induction motors. The forms and types of AC motors include at least asynchronous / synchronous AC motors. Permanent magnet synchronous motors are the most widely used motors among new energy motors. Since heat is generated during the operation of the motor, excessively high temperatures will damage internal components and reduce service life. Moreover, since new energy vehicles have many electronic control components, the space inside the cabin where the new energy motor is installed needs to be sealed. Although the sealed environment improves the protection of the new energy motor, it reduces the heat dissipation capacity of the new energy motor. At present, the motor itself uses a structure with external heat dissipation fins to exchange heat with the outside air to achieve the purpose of heat dissipation. At the same time, a fan is installed at the shaft end of the motor to improve the heat dissipation effect.

[0003] However, in a relatively sealed installation space, although the motor casing is made of metal and is equipped with a fan, its thermal conductivity is relatively low. After the motor casing absorbs heat, if it cannot be discharged in time, a "heat encirclement" will be formed around the outside of the motor body. The air in the installation space will also cause a high temperature due to untimely alternation with the outside world. Over time, if the thermal conductivity is low, the motor will be in a state of heat encirclement, which will affect the service life of the motor. Therefore, combined with the requirements of the installation location of the new energy motor, a new energy motor with high heat dissipation is proposed. Utility Model Content

Specific embodiments

[0038] Next, embodiments of the present utility model will be combined to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0039] As Figures 1 to 6 shown, this embodiment proposes a high heat dissipation type new energy motor, including a machine body. An outer housing 1 is provided on the outside of the machine body. A plurality of heat dissipation fins are provided on the outer wall of the housing 1, and grooves are formed between adjacent two heat dissipation fins. It further includes: an external heat dissipation sleeve 2, an internal heat conduction box 3, a heat conduction mechanism and a temperature reduction mechanism. The external heat dissipation sleeve 2 is sleeved on the housing 1. The internal heat conduction box 3 is arranged in the groove, and the internal heat conduction box 3 contacts the groove. One end of the internal heat conduction box 3 close to the housing 1 is a refrigerating surface, and the refrigerating surface contacts the housing 1, and heat conducting silicone grease is filled at the contact position to improve the heat conduction effect. The heat conduction mechanism is arranged on the external heat dissipation sleeve 2 for leading out the heat dissipated by the housing 1. The temperature reduction mechanism is arranged on the external heat dissipation sleeve 2 for cooling the heat conduction mechanism. Through the cooperation among the external heat dissipation sleeve 2, the internal heat conduction box 3, the heat conduction mechanism and the temperature reduction mechanism, the internal heat conduction box 3 absorbs heat from the housing 1, quickly discharges the heat on the housing 1, quickly conducts the medium (cooling liquid) inside the internal heat conduction box 3 through the heat conduction mechanism, so that the refrigerating surface of the internal heat conduction box 3 continuously maintains a relatively low temperature and contacts the housing 1, achieving the effect of continuous heat absorption and heat conduction. The temperature reduction structure can quickly cool the heat conduction mechanism and the external heat dissipation sleeve 2, avoiding the concentration of heat in the external heat dissipation sleeve 2 and affecting heat dissipation. Compared with the motors of the prior art, its heat dissipation method adds heat conduction and temperature reduction structures, enhances the heat exchange method of only through the motor shell and heat dissipation fins with the outside air in the traditional technology, and improves the heat conduction and heat dissipation efficiency.

[0040] In this embodiment, the heat conduction mechanism is provided on the external heat dissipation sleeve 2, which is used to conduct heat dissipated by the shell 1. The heat conduction mechanism includes: a delivery pipe 4, a refrigerator 5 and a liquid exchange component. Both ends of each built-in heat conduction box 3 are connected to two delivery pipes 4, and multiple delivery pipes 4 are connected to the external heat dissipation sleeve 2. A refrigerator 5 is provided between each adjacent multiple delivery pipes 4. The liquid exchange component is provided on the external heat dissipation sleeve 2 and is used to circulate the coolant in the external heat dissipation sleeve 2. The liquid exchange component includes: a push ring 6, a push frame 7 and The first electric cylinder 8 pushes the ring 6 to slide in the external heat dissipation sleeve 2 and maintains a seal with the inner wall of the external heat dissipation sleeve 2. The push ring 6 is set in the external heat dissipation sleeve 2 along the axial direction of the output shaft of the body. The push frame 7 is set on the external heat dissipation sleeve 2 along the axial direction of the output shaft of the body. One end of the push frame 7 is fixedly connected to the push ring 6. The first electric cylinder 8 is installed on the push frame 7. The output end of the first electric cylinder 8 passes through the push frame 7 and is fixedly connected to the housing 1. The output end of the push frame 7 is a rod structure. The rod structure The end portion is fixedly connected to the push ring 6, and the rod structure passes through the side wall of the external heat dissipation sleeve 2, and slides and seals with the side wall of the external heat dissipation sleeve 2. Specifically, the contraction of the first electric cylinder 8 drives the push frame 7 to move toward the output end of the shell 1. When the push frame 7 moves, it drives the push ring 6 to move in the external heat dissipation sleeve 2, and then the push ring 6 pushes the cooled coolant into the multiple built-in heat conduction boxes 3 through the multiple delivery pipes 4 connected to one side of the external heat dissipation sleeve 2, and the metal is pushed into the metal through the coolant in the built-in heat conduction box 3. The heat on the outer shell is conducted into the coolant. After the temperature of the coolant in the multiple built-in heat-conducting boxes 3 increases, the output end of the first electric cylinder 8 extends, driving the pushing frame 7 to move in the opposite direction, and the coolant in the built-in heat-conducting box 3 is drawn back into the external heat dissipation sleeve 2. When the drawn-back coolant passes through the multiple delivery pipes 4, the delivery pipes 4 are cooled by the refrigerator 5, thereby lowering the temperature of the coolant. At this time, the coolant cooled on the other side of the pushing ring 6 enters the multiple built-in heat-conducting boxes 3 through the multiple delivery pipes 4 on the other side for continued heat conduction.

[0041] Among them, the cooling mechanism is arranged on the external heat dissipation sleeve 2, which is used to cool the shell 1. The cooling mechanism includes: a heat-sinking ring 9, a fixing ring 10, a mounting bracket 11 and a blowing assembly. The heat-sinking ring 9 is sleeved on the circumferential surface of the external heat dissipation sleeve 2, and the contact surface between the heat-sinking ring 9 and the external heat dissipation sleeve 2 is also filled with silicone grease. There are two fixing rings 10, and the two fixing rings 10 are fixedly connected to the external heat dissipation sleeve 2. There are multiple mounting brackets 11, and the multiple mounting brackets 11 are fixedly connected between the two fixing rings 10. A blowing assembly is provided on the multiple mounting brackets 11 for cooling the heat-sinking ring 9. The blowing assembly includes: a fan 12 and a guide frame 13. The fan 12 is provided with multiple fans 12, and multiple fans 12 are all arranged on the mounting frame 11, and the guide frame 13 is fixedly connected to the mounting frame 11. The output end of the fan 12 faces the guide frame 13, and the guide frame 13 is arranged in a trapezoidal shape. A plurality of guide holes 14 and guide grooves 15 are respectively opened inside and on the outer wall of the guide frame 13, so as to facilitate the uniform dispersion of the wind blown out by the fan 12 on the heat-sinking ring 9. Specifically, when the coolant with temperature returns to the external heat dissipation sleeve 2, the heat in the coolant is quickly transferred to a larger heat dissipation area through the heat-sinking ring 9, and then the wind blown out by the fan 12 is evenly guided to the heat-sinking ring 9 through the guide frame 13, thereby quickly dissipating the heat of the coolant.

[0042] In summary, the new energy motor with high heat dissipation performance, when in use, injects coolant (which can be water) into the external heat dissipation sleeve 2, so that the coolant fills the external heat dissipation sleeve 2, multiple delivery pipes 4 and multiple built-in heat-conducting boxes 3. When the shell 1 runs for a long time and generates a high temperature, the first electric cylinder 8 is started, and the first electric cylinder 8 is contracted to drive the push frame 7 to move toward the output end of the shell 1. When the push frame 7 moves, it drives the push ring 6 to move in the external heat dissipation sleeve 2, and then the push ring 6 pushes the cooled coolant through the multiple delivery pipes 4 connected to one side of the external heat dissipation sleeve 2 into the multiple built-in heat-conducting boxes 3. The heat on the metal shell is conducted into the coolant through the coolant in the built-in heat-conducting boxes 3, and the coolant in the multiple built-in heat-conducting boxes 3 absorbs the heat on the metal shell. After the heat temperature rises, the output end of the first electric cylinder 8 extends, driving the pushing frame 7 to move in the opposite direction, and the coolant in the built-in heat-conducting box 3 is drawn back into the external heat dissipation sleeve 2. When the drawn-back coolant passes through multiple delivery pipes 4, the delivery pipes 4 are cooled by the refrigerator 5, thereby reducing the temperature in the coolant. At this time, the cooled coolant on the other side of the pushing ring 6 enters the multiple built-in heat-conducting boxes 3 through the multiple delivery pipes 4 on the other side for continued heat conduction. When the heated coolant returns to the external heat dissipation sleeve 2, the heat in the coolant is quickly transferred to a larger heat dissipation area through the heat-dissipating ring 9. After that, the wind blown out of the fan 12 is evenly guided to the heat-dissipating ring 9 through the guide frame 13, thereby quickly and efficiently dissipating the coolant inside the external heat dissipation sleeve 2.

[0043] It should also be supplemented that the external heat dissipation sleeve 2, the delivery pipe 4 and the internal heat conduction box 3 are all made of relatively thin metal materials, with better heat conduction performance. And the cooler 5 uses a common semiconductor electronic cooler on the market (such as the semiconductor refrigeration kit sold by the Taobao merchant "Shenzhen Haida Gaoke Electronic Business Firm" under Alibaba). It is small in size and can be refrigerated when powered on. There are water inlet pipe and water outlet pipe provided on the semiconductor electronic cooler 5. The water outlet end of each delivery pipe 4 is connected to the water inlet pipe of the cooler 5, and the water inlet end of the delivery pipe 4 is connected to the water outlet end of the cooler 5. When water circulates between the delivery pipe and the cooler 5, the water is cooled by passing through the cooler 5, achieving the purpose of reducing the water temperature and realizing the refrigeration effect.
