AI Technical Summary

Technical Problem

The existing aluminum liquid-cooled plates have poor load-bearing capacity and are prone to deformation, resulting in a reduced heat dissipation capacity, and the weight increases after strengthening the bracket, affecting transportation and use.

Method used

Liquid-cooled plates are made of titanium-aluminum composite plates. The composite aluminum layer on the runner plate melts during brazing, adhering the flat plate and the runner plate into a whole, and using the titanium layer to improve strength and load-bearing capacity.

Benefits of technology

The problem of poor load-bearing capacity of aluminum liquid-cooled plates is solved, the strength and heat dissipation capacity of liquid-cooled plates are improved, weight and volume are reduced, and the cost and complexity of strengthening the brackets are avoided.

Abstract

The utility model relates to the technical field of liquid cooling plates, and discloses a titanium-aluminum composite liquid cooling plate which comprises a flat plate and a runner plate, the flat plate comprises a first base material aluminum layer, and the upper surface of the first base material aluminum layer is in cold rolling connection with a first base material titanium layer; the runner plate comprises a second base material aluminum layer, a composite aluminum layer is arranged on the side, close to the first base material aluminum layer, of the second base material aluminum layer, and a second base material titanium layer is connected to the side, away from the first base material aluminum layer, of the second base material aluminum layer in a cold rolling mode. According to the titanium-aluminum composite liquid cooling plate, the problems that a traditional aluminum liquid cooling plate is poor in bearing capacity and prone to deformation are solved, compared with the scheme that the traditional aluminum liquid cooling plate and a reinforcing support are arranged, the titanium-aluminum composite liquid cooling plate is lighter in weight, larger space can be reserved for a battery cell, and compared with the traditional liquid cooling plate, the titanium-aluminum composite liquid cooling plate is higher in strength, lighter in weight and smaller in occupied size.
