Bulging mold structure and method for preparing liquid cooling plate

Abstract

The invention discloses a bulging mold structure, comprising a runner mold and a plurality of runner air inlet molds. The edges of the runner mold and the runner air inlet molds are connected in series through guide columns; the outer sides of the guide columns are sleeved with high-pressure springs; the upper sides of the edges of the runner air inlet molds are connected with a formed metal plate through positioning pins; the outer sides of the short edges of the runner air inlet molds are connected with mold lifting blocks; the outer sides of the long edges of the runner air inlet molds are connected with mold locking blocks; the formed metal plate comprises a runner plate; and the runner plate is connected with a light plate through a connector. According to the invention, the heat of a battery module can be continuously carried through a runner, so that the temperature equalization effect is achieved, the highest mold thickness can be set according to the processing range of production equipment, a mold can be manufactured according to the production capacity, the effect of one mold with multiple cavities is realized, and the mold has the characteristics of high production efficiency, low production cost, small required molding equipment and high flexibility.

Description

technical field [0001] The invention relates to the technical field of liquid cold plates, in particular to a bulging mold structure and a method for preparing liquid cold plates. Background technique [0002] Electric vehicles are a kind of new energy vehicles, and now more and more people pay attention to them. In electric vehicles, the power battery is its core component. The main requirements for power batteries are: high energy density, long cruising range and fast charging. These requirements require the battery to generate more and more heat, and the heat generation speed is faster and faster. The resulting problem is that the battery is prone to Thermal abuse, therefore, thermal management of the battery. [0003] At present, the liquid cooling plate mainly adopts the runner plate after stamping and forming of the aluminum alloy composite plate, and forms a closed flow channel by brazing with the aluminum bare plate, and finally obtains the liquid cooling plate. D...

[0005] The above-mentioned method for processing the flow channel plate of the liquid-cooled plate from a plastic plate to a flow channel plate is to place one side of the plastic plate on a forming mold, and the other side is in a pressure environment, and the pressure of the pressure environment makes the all The plastic flat plate can be plastically deformed along the direction of the prefabricated flow channel on the forming mold to form a bulging plate with a groove path. Its processing and forming method is consistent with this patent, but its processing efficiency is low and it is not suitable for large Large-scale mass production, or mass production requires multiple molds and multiple production equipment
