Description

technical field [0001] The invention belongs to the technical field of liquid-cooled plate structure optimization, and in particular relates to a liquid-cooled plate structure size optimization method based on Hyperstudy and Fluent joint simulation. Background technique [0002] Liquid cold plates are often used in the cooling system of automotive power batteries. [0003] In the power battery system, the battery generates excess heat. The heat is transferred through the contact between the battery or the module and the surface of the liquid cooling plate, and is finally taken away by the cooling liquid passing through the internal flow channel of the liquid cooling plate to realize the heat dissipation of the power battery.

Problems solved by technology

[0004] In the existing liquid cooling plate, the width of each flow channel is usually equal, but due to the different length and shape of each flow channel, the flow distribution in each flow channel is uneven, which easily leads to the gap between the regions in the power battery system. The heat dissipation effect is uneven, which leads to poor temperature consistency in the overall power battery system, affects the service life, and even causes the risk of thermal runaway;

[0005] In addition, each channel of the liquid cold plate is usually optimized manually, and the optimal solution is often not obtained after repeated operations, which makes the optimization of the liquid cold plate time-consuming and inefficient.
