Description

Technical Field

[0001] This utility model relates to the field of motor heat dissipation technology, and in particular to a high-efficiency heat dissipation device for a new energy trailer drive motor. Background Technology

[0002] As the core power component of new energy trailers, the drive motor's performance directly affects the vehicle's range and reliability. In practical applications, trailers often face conditions such as prolonged high-speed driving and heavy-load uphill climbing. The continuous high-load operation of the drive motor generates a large amount of heat. If heat cannot be dissipated in time, it will lead to decreased motor efficiency, aging of insulation materials, and even safety accidents. Therefore, efficient heat dissipation technology has become one of the key factors restricting the improvement of new energy trailer performance.

[0003] Currently, the main heat dissipation methods for drive motors of new energy trailers include air cooling, liquid cooling, and phase change material heat dissipation. Air cooling technology is widely used due to its simple structure and low cost. It usually uses fixed heat dissipation fins in conjunction with an axial fan to remove heat through air convection. Liquid cooling technology uses coolant circulation to achieve efficient heat dissipation, but its system is complex and has high maintenance costs. Phase change material heat dissipation relies on the heat absorption characteristics of material phase change, which has the problem of insufficient heat dissipation sustainability. As the power density of motors continues to increase (e.g., from 1.5kW / kg to 3kW / kg), traditional heat dissipation technologies are becoming increasingly inadequate in dealing with the heat dissipation requirements under local high temperatures and dynamic operating conditions.

[0004] Insufficient heat dissipation efficiency and uniformity: Traditional air-cooled devices use fixed heat sinks and fans, which can only passively cool the surface of the motor. They cannot accurately dissipate heat from local high-heat areas such as windings and bearings, resulting in uneven temperature distribution on the motor surface. Some areas are prone to the "heat island effect", which will accelerate the aging of the motor in the long run.

[0005] Poor dynamic adaptability: Under complex road conditions (such as frequent start-stop and steep slope driving), the motor load of new energy trailers fluctuates greatly. Traditional heat dissipation systems lack dynamic adjustment capabilities and cannot adjust the heat dissipation intensity according to real-time operating conditions. This results in a contradiction between insufficient heat dissipation under high load and energy waste under low load, affecting the overall vehicle energy efficiency.

[0006] High maintenance costs: Although liquid cooling systems have high heat dissipation efficiency, coolant is prone to leakage and pipe blockage, and the complex structure makes maintenance difficult; the heat dissipation performance of phase change materials deteriorates significantly after multiple phase changes, requiring frequent material replacement, which is not economical. Utility Model Content

[0007] The purpose of this invention is to solve the problems of low heat dissipation efficiency, uneven temperature distribution, poor dynamic adaptability and high maintenance cost of the drive motor in the prior art, and to propose a high-efficiency heat dissipation device for the drive motor of new energy trailers.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency heat dissipation device for a new energy trailer drive motor, comprising a housing, an installation plate fixedly installed inside the housing, and a heat conduction heat dissipation structure fixedly installed on the outer surface of the installation plate; the heat conduction heat dissipation structure comprises a body, a set of aluminum frames fixedly installed on the outer surface of the body, a heat-conducting frame snapped onto the outer surface of the aluminum frames, an installation frame fixedly installed on the outer wall of the housing, heat dissipation fins fixedly installed on the opposite side of the installation frame, a set of mounting seats fixedly installed on the outer surface of the installation frame, and an electric fan fixedly installed on the outer surface of each mounting seat.

[0011] A fixing plate is fixedly installed on the outer surface of the ball bearing slide seat with screws, and a diverter pipe is fixedly installed on the outer surface of the fixing plate.

[0012] Preferably, a set of jet nozzles is fixedly connected to the outer wall of the diversion pipe, and a connecting flange pipe is connected to the outer wall of the diversion pipe.

[0013] Preferably, the mounting part of the body is screwed to the outer surface of the mounting plate, and the rear side of the body is attached to the outer surface of the heat-conducting frame.

[0014] Preferably, the outer surface of the heat-conducting frame and the outer surface of the heat dissipation fins are in contact with each other, and the outer surface of the heat dissipation fins and the air inlet end of the electric fan are in cooperation with each other.

[0015] Preferably, the outer surface of the housing is provided with a sliding groove, and the outer wall of the connecting flange pipe is slidably disposed inside the sliding groove.

[0016] Preferably, the outer surface of the outer casing is provided with a sliding groove, and the outer wall of the connecting flange pipe is slidably disposed inside the groove.

[0017] Preferably, the top of the housing is hinged to an access door, and a handle is fixedly connected to the outer wall of the access door.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a three-dimensional heat dissipation system of "conduction-convection-dynamic coverage" is constructed through the coordinated design of a heat conduction heat dissipation structure, a forced convection heat dissipation structure, and a transverse air-cooling mechanism. The aluminum frame and heat-conducting frame enable rapid heat conduction, the heat dissipation fins and electric fan accelerate air convection, and the movable air nozzles eliminate heat dissipation dead zones and ensure uniform temperature distribution by periodically covering the motor surface. In addition, the design of the maintenance door further improves the maintainability of the device. Compared with traditional heat dissipation methods, this device can more efficiently and stably ensure the operation of the new energy trailer drive motor and extend its service life.

[0019] 2. In this utility model, a modular composite heat dissipation architecture is adopted. Through the innovative design of aluminum-based heat conduction components, heat is transferred rapidly in milliseconds. The integrated design of the mounting frame and heat dissipation fins maximizes the heat exchange area. The electric fan and the transverse air-cooling mechanism form an intelligent dynamic heat dissipation matrix. The former continuously enhances air convection, while the latter performs full-area scanning cooling through a screw-driven jet nozzle. The cooling intensity can be automatically adjusted according to the real-time temperature of the motor. In addition, the device reserves a standardized maintenance interface, which greatly improves the environmental adaptability and full life cycle economy of the new energy trailer drive motor while ensuring heat dissipation efficiency.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4 As shown, this utility model provides a high-efficiency heat dissipation device for a drive motor of a new energy trailer. It is characterized by comprising a housing 1, an mounting plate 13 fixedly installed inside the housing 1, and a heat conduction heat dissipation structure 2 fixedly installed on the outer surface of the mounting plate 13. The heat conduction heat dissipation structure 2 includes a body 201, a set of aluminum frames 202 fixedly installed on the outer surface of the body 201, a heat-conducting frame 203 engaging on the outer surface of the aluminum frames 202, and an mounting frame 204 fixedly installed on the outer wall of the housing 1.

[0025] The overall effect of embodiment 1 is that the heat conduction and heat dissipation structure 2 is fixed inside the outer shell 1 by the mounting plate 13, including the body 201, aluminum frame 202, heat conduction frame 203 and mounting frame 204. The effect is as follows: the heat conduction path is established by the body 201 adhering to the heat source of the motor, the aluminum frame 202 (aluminum material conducts heat quickly) conducts heat to the heat conduction frame 203, and then diffuses it to the outside of the outer shell 1 through the mounting frame 204. The structure supports the aluminum frame 202 to support the heat conduction frame 203, ensuring a stable thermal contact area and adapting to vibration environments (such as trailer driving).

[0026] Example 2: Figures 1-4 As shown, heat dissipation fins 205 are fixedly installed on the opposite side of the mounting frame 204, and a set of mounting seats 206 are fixedly installed on the outer surface of the mounting frame 204. An electric fan 207 is fixedly installed on the outer surface of each mounting seat 206.

[0027] The overall effect of embodiment 2 is that the structure consists of a mounting frame 204 with heat dissipation fins 205, a mounting base 206 and an electric fan 207 on the outside, which achieves the following effects: the heat dissipation area is increased, the heat dissipation fins 205 increase the heat radiation area and accelerate heat dissipation, and the forced convection is enhanced: the electric fan 207 accelerates the air flow and exhausts hot air from the area of ​​the heat dissipation fins 205, thereby improving the heat dissipation efficiency.

[0028] Example 3: As Figures 1-4As shown, a transverse air-cooling mechanism 3 is provided in the space between the inner wall of the outer casing 1 and the mounting plate 13. The transverse air-cooling mechanism 3 includes a first motor 301. The mounting part of the first motor 301 and the outer surface of the outer casing 1 are fixedly connected by screws. A lead screw 302 is fixedly connected to the output end of the first motor 301. A set of limiting rods 303 are fixedly inserted into the opposite side of the outer casing 1. A ball bearing sliding seat 304 is threadedly connected to the outer wall of the lead screw 302. A fixing plate 305 is fixedly installed on the outer surface of the ball bearing sliding seat 304 by screws. A diversion pipe 306 is fixedly installed on the outer surface of the fixing plate 305. A set of air nozzles 307 are fixedly connected to the outer wall of the diversion pipe 306. A connecting flange pipe 308 is connected to the outer wall of the diversion pipe 306.

[0029] The overall effect of embodiment 3 is as follows: The structure consists of a transverse air-cooling mechanism 3, which drives the lead screw 302 via the first motor 301, causing the ball bearing slide seat 304 to move the diversion pipe 306 and the jet nozzle 307 laterally. The connecting flange pipe 308 connects to the external air source, achieving the following effect: dynamic air-cooling coverage: The jet nozzle 307 moves laterally along the lead screw 302, and performs large-scale forced air cooling on the surface of the body 201 through the ventilation holes 14. The optimized airflow distribution of the moving jet nozzle 307 avoids the temperature difference caused by fixed-position cooling, making the surface temperature of the motor more uniform.

[0030] Example 4: Figures 1-4 As shown, the mounting part of the main body 201 is screwed to the outer surface of the mounting plate 13. The rear side of the main body 201 is attached to the outer surface of the heat-conducting frame 203. The outer surface of the heat-conducting frame 203 is attached to the outer surface of the heat dissipation fins 205. The outer surface of the heat dissipation fins 205 is engaged with the air inlet of the electric fan 207. A sliding groove is provided on the outer surface of the outer shell 1. The outer wall of the connecting flange pipe 308 is slidably disposed inside the groove. The top of the outer shell 1 is hinged to the inspection door 11. A handle 12 is fixedly connected to the outer wall of the inspection door 11. Multiple ventilation holes 14 are provided on the outer wall of the mounting plate 13. The output end of the jet nozzle 307 is engaged with the outer surface of the main body 201 through the ventilation holes 14.

[0031] The overall effect of embodiment 4 is as follows: structural composition: the body 201 is attached to the heat-conducting frame 203, the heat dissipation fins 205 are matched with the fan 207, the air nozzle 307 is aligned with the body 201 through the ventilation hole 14, and the outer shell 1 is provided with an inspection door 11. The effect achieved is: coordinated heat dissipation: conduction path: motor heat → body 201 → heat-conducting frame 203 → heat dissipation fins 205 → fan 207 exhaust, air cooling path: the air nozzle 307 directly cools the body 201 through the hole 14, and maintenance convenience: the inspection door 11 facilitates the replacement of internal components.

[0032] Practical Methods and Working Principles: Heat Dissipation Process: Heat Conduction Stage Path: Heat generated on the surface of the drive motor → Body 201 (directly in contact with the motor heat source) → Aluminum Frame 202 (using the high thermal conductivity of aluminum for rapid heat transfer) → Heat Conducting Frame 203 → Heat Dissipation Fins 205 (increasing the heat dissipation area). Key Points: The structural design of the aluminum frame 202 ensures heat conduction efficiency and supports the heat conducting frame 203, preventing vibration from causing poor contact. The contact surfaces between the heat conducting frame 203 and the heat dissipation fins 205 must be tight (e.g., fixed by clips or welding) to reduce thermal resistance. Forced Convection Stage: Electric Fan 207: Accelerates airflow, forcibly expelling hot air from the surface of the heat dissipation fins 205 from the outer casing 1, forming a stable heat dissipation airflow channel. Lateral Air-Cooling Mechanism 3: Working Process: The first motor 301 drives the lead screw 302 to rotate → the ball bearing sliding seat 304 moves laterally along the lead screw 302 → driving the splitter pipe 306 and the jet nozzle 307 to move synchronously. Airflow Path: External compressed air. The air enters the distribution pipe 306 through the connecting flange pipe 308 → the jet nozzle 307 sprays high-pressure airflow onto the surface of the main body 201 through the ventilation hole 14 → directly cooling the heat source area of ​​the motor. The dynamic and coordinated heat dissipation electric fan 207 continuously dissipates heat. The horizontally moving jet nozzle 307 periodically covers the surface of the motor, forming a "static + dynamic" dual cooling effect. The position of the ventilation hole 14 is precisely matched with the moving trajectory of the jet nozzle 307 to ensure that the cooling airflow acts evenly on the main body 201. During the operation, the drive motor is turned on at the same time as the electric fan 207 starts, and the first motor 301 of the horizontally moving air-cooling mechanism 3 works synchronously (which can be linked by the controller). An external air source (such as a vehicle-mounted air compressor) supplies air to the distribution pipe 306 through the connecting flange pipe 308. During the operation, the jet nozzle 307 moves back and forth at a set speed, covering the key heat-generating areas of the motor (such as windings and bearings). The heat dissipation fins 205 continuously dissipate heat through natural convection and forced convection by the fan 207.

The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric telescopic pole 8, battery 27, water pump 2, and motor 21 will not be explained in detail.
