Abstract
A heat exchanger has multiple laminated fins. Each finhas multiple topsand multiple bottomsarranged to have a preset acute angle γ (for example, 30 degrees) to an air flow line at an air inlet and to make an air flow in a cavity region behind each of multiple heat transfer tubestoin an air flow direction at an air outlet. This design of the finsproduces effective secondary flows of the air to improve the heat transfer efficiency and makes an additional contribution to heat exchange, due to the air flow in the cavity region behind each of the heat transfer tubestoin the air flow direction. This arrangement effectively prevents separation of the air flow and a local speed increase of the air flow, while improving the overall heat exchange efficiency by production of the effective secondary flows of the air.
