Abstract

The invention relates to a streamline-based method for designing inner flow passages of cooling plates, and belongs to the technical field of computer aided design. The method comprises an obtaining step and a construction step, wherein the obtaining step comprises obtaining flow field distribution in a flow passage distribution area with a flow passage inlet and a flow passage outlet; and the construction step comprises constructing inner flow passages of cooling plates by taking a streamline in the flow field distribution as a criterion according to the quantity and distribution of designed flow passages. According to the method, a cooling plate inner flow passage distribution scheme with relatively small flow resistance can be designed, and the requirement for the design experiences of the designers can be reduced.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a method for designing an internal flow channel of a cooling plate based on streamlines. Background technique [0002] Using a cold plate for cooling can not only quickly take away the heat generated by the equipment, but also has high reliability and stability, making it a preferred heat dissipation device. [0003] During the working process, its internal flow channel will produce flow resistance to the movement of the coolant. If the flow resistance is too large, it will significantly increase the power consumption of the pump. Therefore, in the design process, it is usually necessary to compare multiple design schemes in order to Select the design scheme with the smallest flow resistance as the target scheme, for example, (1): According to the design working conditions, it is required to design the distribution structure of the outlet inlet 01, the outlet 02 and...
