AI Technical Summary
In new energy vehicles, during the crimping process of the two-color hose between liquid-cooled plates, the sealing performance is poor due to the close distance, which is difficult to assemble and easily shake. The existing crimping process cannot meet the sealing requirements.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile cooling systems and is used for manufacturing radiator water chambers, specifically a cold plate for large cylindrical new energy electric cores with a clamping structure. Background Technique
[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources or use conventional vehicle fuels and adopt new in-vehicle power devices, integrating advanced technologies in vehicle power control and driving, and forming vehicles with advanced technical principles, new technologies, and new structures.
[0003] In new energy vehicle models, most of the power steering systems are electric power steering systems. The electric power steering system, abbreviated as EPS, has advantages such as energy conservation and environmental protection, but the assistance provided is small and cannot meet the assistance requirements of large buses. In new energy vehicles and hybrid vehicles, low-temperature radiators are used to cool the motor and controller, and motor radiators are installed in new energy vehicles to cool the motor.
[0004] In the actual production process, when the cooling scheme changes to two-tube cooling of one electric core, the distance between the liquid cooling plates becomes closer, and the previous quick-insert structure of the nozzle is changed to a crimping process connection. According to the above crimping process in the implementation project, due to the small intermediate distance, there are two major difficulties in terms of the limited gripping area, etc. The force for pressing the double-color rubber tube into the nozzle cannot be too large, resulting in the double-color tube being difficult to pour in or unable to be assembled to the bottom. Due to the limited intermediate position, when the double-color rubber tube is pressed into the nozzle, the intermediate product shakes, which will seriously affect the sealing performance and lead to sealing failure. Therefore, it is necessary to propose an automobile low-temperature radiator to solve the above problems. Content of the Utility Model
[0005] In order to solve the above problems, the utility model provides a cold plate for large cylindrical new energy electric cores with a clamping structure, which includes a plurality of clamping combinations. Each clamping combination includes a joint assembly and a crimping tube assembly connected to the joint assembly by a clamping method. The joint assembly includes a joint mounting plate and a nozzle structure integrally connected to the joint mounting plate by injection molding. A groove structure is provided on the outer edge of the nozzle structure. By setting the groove structure and applying lubricating oil on the outer edge of the groove structure, the internal pressure when the crimping tube assembly is clamped into the nozzle structure can be reduced, and the smoothness when the crimping tube assembly is clamped with the nozzle structure can be improved.
[0006] A further improvement of the utility model is that two nozzle structures are provided on the upper end surface of the joint mounting plate, and the nozzle structures penetrate through the joint mounting plate.
[0007] A further improvement of the present utility model lies in that: a reinforcing rib structure is provided inside the joint mounting plate, which can enhance the strength of the joint mounting plate and prevent the joint mounting plate from cracking due to excessive stress when installing the nozzle structure and the crimping pipe assembly.
[0008] A further improvement of the present utility model lies in that: the outer side of the upper end face of the nozzle structure is in an inclined plane structure.
[0009] A further improvement of the present utility model lies in that: the slope at the position where the lower end of the crimping pipe assembly contacts the nozzle structure is the same as the slope of the outer inclined plane of the nozzle structure.
[0010] A further improvement of the present utility model lies in that: step surfaces are provided on both the upper and lower end faces on the outer side of the joint mounting plate. The provision of the step surfaces can embed the bottom of the crimping pipe assembly on the step surfaces, achieving the stability after overall installation and preventing shaking during use after installation.
[0011] A further improvement of the present utility model lies in that: a groove structure is provided inside the crimping pipe assembly.
[0012] A further improvement of the present utility model lies in that: the protruding inclined plane structures on the outer side of the nozzle structure are mutually clamped, and the groove structure inside the crimping pipe assembly and the protruding inclined plane structures on the outer side of the nozzle structure are mutually clamped.
[0013] The present utility model is provided with a groove structure at the outer edge of the nozzle structure and lubricating oil is applied inside the groove structure. When the crimping pipe assembly is pressed into the nozzle structure, due to the provision of the groove structure, the internal pressure when the crimping pipe assembly is snapped into the nozzle structure can be reduced, thereby reducing the frictional force between the two contacts. Coupled with the lubricating oil applied outside the groove structure, the snapping action can be made smoother, ensuring that the nozzle structure can smoothly enter the crimping pipe assembly. At the same time, due to the mutual clamping of the groove structure inside the crimping pipe assembly and the protruding inclined plane structures on the outer side of the nozzle structure, the sealing effect after the crimping pipe assembly and the nozzle structure are clamped together can be ensured.
