Harmonica-shaped tube type liquid cooling plate fixing device, design method, battery and vehicle

Abstract

The invention relates to a harmonica-shaped tube type liquid cooling plate fixing device, a design method, a battery and a vehicle. The fixing device comprises a fixing buckle, a main fixing support, an auxiliary fixing support and a fixing pin. One end of the main fixing support is welded with one end of a harmonica-shaped tube in the harmonica-shaped tube type liquid cooling plate assembly, and the other end of the main fixing support is connected with the battery box body through a fixing pin; one end of the auxiliary fixing support is welded with one end of a harmonica-shaped tube in the harmonica-shaped tube type liquid cooling plate assembly, and the other end of the auxiliary fixing support is connected with the battery box body through a fixing pin; an elastic element at the bottom end of the harmonica-shaped tube type liquid cooling plate assembly is in contact with the battery box body; and the upper end of the fixing pin is meshed with the fixing buckle. According to the device, the highest height of Z-direction movement of the harmonica-shaped tube type liquid cooling plate in the mounting process can be limited, Z-direction jumping of the liquid cooling plate caused by factors such as shaking of a mounting production line, vibration of a tool trolley and manual operation is avoided, and Z-direction movement of the harmonica-shaped tube type liquid cooling plate assembly is limited due to interference fit between the lower end of the device and the battery box body.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a harmonica tube type liquid cold plate fixing device, a design method, a battery and a vehicle. Background technique [0002] At present, the thermal management method of power batteries is mainly liquid cooling, because liquid cooling has the advantages of high efficiency, low cost, no noise and vibration, and large cooling power. The main components of the liquid cooling system are liquid cooling plates and water pipes. There are two main types of liquid cooling plates: stamped brazing plates and harmonica tube liquid cooling plates. Among them, the harmonica tube-type liquid cold plate is named because the main liquid cold plate is a bar-shaped liquid cold plate with harmonica-shaped porous microchannels. It has the advantages of light weight, universal modular design, low cost, and short development cycle. It has a wide range of applications in the field of battery ther...

This application realizes runner plate runner molding through mold core and inflation technology, and the base used in the runner molding process can be shared, which reduces the mold cost and shortens the development cycle, but because the Z direction is not fixed during installation, it may Due to the shaking of the installation production line, the vibration of the tooling trolley, and human operation, the liquid cooling plate will jump in the Z direction, causing the fixing hole of the harmonica tube liquid cooling plate to deviate from the correct installation position and overlap the fixing pin. The cold plate is warped and bent, and there is a big hidden danger of installation and fixation

[0008] The patent with the publication number CN113258399A discloses a wire crimping device and a crimping method. The device includes a supporting body, a mold cover, a mold, an eddy current heating curved plate, a hydraulic cylinder and a hanging beam, and is controlled by a hydraulic cylinder on the supporting body. The mold is closed and separated to realize the crimping of the wires to be crimped, and the wires to be crimped are heated by the eddy current heating curved plate, and the heated wires are convenient for crimping, which can reduce the performance requirements of the hydraulic machine; the hydraulic method is simple, and the crimping quality Better, the threaded connecting rod connected by the hanging beam and the locking buckle fix the wire to be crimped, reduce the error caused by the crimping caused by the misalignment of the wire to be crimped and the mold, and improve the crimping quality, but it is not suitable for Fixing of Harmonica Tube Type Liquid Cold Plate
