AI Technical Summary

Technical Problem

Existing heat exchangers struggle to effectively match flow resistance and heat exchange area when handling oily and watery fluids, resulting in poor heat exchange performance and difficulty in simultaneously ensuring pressure resistance.

Method used

By adjusting the height and fin structure of the oil and water fluid channels in the heat exchanger, ensuring that the height of the oil fluid channel is greater than that of the water fluid channel, and that the fin design satisfies the relationship 0.7≤(λ1·H)/(λ2·h)≤3, the matching of flow resistance and heat exchange area is optimized.

Benefits of technology

It improves the heat exchange performance of the heat exchanger while ensuring the reliability and pressure resistance of the product, and enhances the heat exchange effect and flow uniformity of the fluid.
