Benefits of technology

The present invention provides a heat dissipation fin for heat exchangers that improves heat exchange efficiency by adjusting the distance and height of louvers arranged in layers, as well as the interlayer distance between louvers of different layers. The louvers are inclined towards the middle of the heat dissipation fin in a straight line in a symmetrical fashion, and the distance between louvers is gradually increased from the outermost end of a first half part of the heat dissipation fin to the middle of the heat dissipation fin, or the height of the louvers is gradually increased from the outermost end of a first half part of the heat dissipation fin to the middle of the heat dissipation fin, or the interlayer distance between louvers of different layers is gradually decreased from the outermost end of a first half part of the heat dissipation fin to the middle of the heat dissipation fin. This reduces air resistance and maximizes heat dissipation efficiency.

Problems solved by technology

However, the louvers of the conventional heat dissipation fin are arranged with the same bending pitch P1 with the result that the improvement of the heat dissipation efficiency is limited.
As the number of the louvers 5a is increased, however, the pressure drop amount of air is increased, and therefore, the heat dissipation efficiency is reduced at low speed.

Abstract

A heat dissipation fin for heat exchangers disposed between tubes for heat exchangers includes pluralities of louvers arranged in several layers. The louvers of the respective layers are inclined toward the middle of the heat dissipation fin in a straight line in a symmetrical fashion, and the distance between the louvers is gradually increased from the outermost end of a first half part of the heat dissipation fin to the middle of the heat dissipation fin, whereby the air resistance is decreased and the heat dissipation efficiency is improved.
