Title:
COMPACT HEAT EXCHANGER AND ASYMMETRIC AIRFOIL HEAT EXCHANGE PLATE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/205765
Kind Code:
A1
Abstract:
The present invention provides a compact heat exchanger and an asymmetric airfoil heat exchange plate thereof. The present invention is simple in structure and reasonable in design, and can effectively reduce or eliminate the problem of uneven flow distribution of heat exchange channels while maintaining enhanced heat transfer. The asymmetric airfoil heat exchange plate comprises a heat exchange plate body and asymmetric airfoil fins disposed in a flow channel of the heat exchange plate body. The asymmetric airfoil fins are bent towards one side. The asymmetric airfoil fins are sequentially arranged at intervals in a fluid flow direction. The bending arc directions of the asymmetric airfoil fins in the same column are the same, and the bending arc directions of the asymmetric airfoil fins in adjacent columns are opposite. A discontinuous S-shaped channel is formed between every two adjacent rows of asymmetric airfoil fins.
