Two-phase flow cold plate with bionic structure

Abstract

The invention discloses a two-phase flow cold plate with a bionic structure. The equipment includes a cold plate base body and a cover plate, wherein the cold plate base body is provided with a flow channel inlet, a flow channel outlet, a first main flow channel, a second main flow channel, a third main flow channel and branch flow channels. The first main runner is parallel to the second main runner, the third main runner is parallel to the branch runner, and the first main runner is perpendicular to the branch runner. The branch runners are symmetrically distributed on the two sides of the first main runner, the second main runners are symmetrically distributed on the two sides of the first main runner, and the runner inlets and the runner outlets are located in the middles of the two sides of the cold plate base body. The runner inlet is connected with the first main runner, and the runner outlet is connected with the third main runner. A cooling liquid flows into the first main flow channel from the flow channel inlet, then is divided into the branch flow channels, then is gathered in the second main flow channel, finally enters the third main flow channel and flows out from the flow channel outlet. According to the invention, the flow channel design refers to the structure of banana veins, and the cooling effect and the temperature uniformity of the cold plate are improved.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment temperature control, in particular to a two-phase flow cold plate with a bionic structure. Background technique [0002] Cold plate is a common heat dissipation structure. Compared with air cooling, the liquid cooling system with cold plate as the main structure has better and more reliable heat dissipation performance. It is currently the mainstream solution for cooling batteries. [0003] With the continuous development of electric vehicles, the power of power batteries is also increasing, the heat flux density is increasing, and its heat dissipation requirements are also increasing. The cooling of the power battery needs to take into account the highest value and uniformity of the temperature at each point of the battery. Common parallel channel cold plates have been difficult to meet the heat dissipation requirements of power batteries. [0004] In order to improve the heat diss...

Problems solved by technology

However, because the material of the cold plate and the composition of the cooling liquid need to take into account the cost, and increasing the mass flow rate of the cooling liquid will also increase the corresponding power consumption, so the optimal design of the heat exchange structure of the cold plate is important for the heat dissipation effect of the cold plate and Focus on Uniformity Optimization
