Description

TECHNICAL FIELD

[0002] The cold liquid plate is a functional component for heat transfer and heat dissipation, which is mainly composed of a substrate, a flow channel, a cover plate, and an interface. In the field of new energy vehicles, the cold liquid plate can be used on the power battery pack, usually attached to the bottom, side or top of the battery module. During the charging and discharging process of the electric vehicle battery, heat will be generated, especially during high-rate charging or intense driving, the local temperature can rise above 50℃. The cold liquid plate absorbs heat through the circulation of cooling liquid to control the battery temperature within the optimal working range, avoiding overheating which may cause capacity attenuation or safety hazards (such as thermal runaway). The temperature difference between different positions in the battery pack (such as the edge and the center) may exceed 10℃. The flow channel design of the cold liquid plate can ensure uniform heat dissipation of each battery cell, with a temperature difference controlled within ±2℃, thereby improving the consistency and lifespan of the battery pack.

[0003] During the processing of the cold liquid plate, brazing is performed. Brazing is a critical process that ensures the sealing and heat dissipation efficiency of the cold liquid plate.

During the brazing process, the roller mechanism continuously transports the cold liquid plate to be brazed, and the brazing tunnel furnace continuously feeds the products into the furnace, resulting in the phenomenon of clamping the furnace.

[0071] Since the second roller mechanism 3 transports the cold liquid plate 5 to the furnace front centering mechanism 2, the grating sensor 22 is arranged at the middle position of the centering rack 21, and when the cold liquid plate reaches the middle position of the centering rack 21, the cold liquid plate will block the light path of the grating, and the position information of the cold liquid plate can be obtained by detecting the change of the grating signal. When the cold liquid plate completely blocks the grating, the change of the grating signal will be used as a trigger signal to inform the PLC control system to start the centering program, and the PLC control system controls the motor 259 to move, so that the first centering rod 231 and the second centering rod 241 move towards the middle position of the centering rack 21, and the cold liquid plate is centered. The running time T of the first centering rod 231 and the second centering rod 241 towards the centering rack 21 is obtained by preliminary test, and the cold liquid plate is centered in the running time T. After the running time T, the PLC control system controls the motor 259 to reverse, so that the first centering rod 231 and the second centering rod 241 move towards the two sides of the centering rack 21, and at the same time the cold liquid plate is loosened and continues to enter the first roller mechanism 1.

[0072] The grating sensor is a kind of prior art applied to the embodiment, the PLC control system converts the grating signal into an electric signal by collection, and then realizes the precise start and stop of the production equipment, which is a mature and widely used automatic control technology. In the present application, the time T in the running program of the motor 259 controlled by the PLC control system can be set according to the actual production, and too much statement is not made here. It should be understood that based on the above device, the frequency of the brazing tunnel furnace jamming can be reduced in the automatic production process of the cold liquid plate. In one specific embodiment, the economic loss caused by the brazing tunnel furnace jamming is about 3W, and the above device can effectively avoid the brazing tunnel furnace jamming and improve the production efficiency.
