Description

Technical field [0001] The present invention relates to the field of heat generating techniques, and more particularly to a method of performing an array micro-track heat exchanger considering manufacturing constraints. Background technique [0002] As energy is increasing, scarce, high-efficiency heat exchange techniques will become a key to overcome the future. The heat exchanger is a device that transmits a fluid in some way to another fluid in an engineering, widely used in industrial production. Compared with conventional heat exchanger, the micro-track heat exchanger is small, high heat transfer coefficient, high heat exchange efficiency, and has excellent pressure resistance. However, the micro-track heat exchanger is high, and the manufacturing cost is high, and the improvement is to be further optimized. [0003] Conventional array micro-track heat exchangers have gaps between design and manufacturing. Since the existing manufacturing process cannot meet the machining ac...
