Heat exchanger

Abstract

Disclosed is a heat exchanger. The heat exchanger includes a plurality of plates superimposed on one another, and a plurality of heat transfer fins formed on the plurality of plates, and shaped into an airfoil, wherein a channel of a fluid between the superimposed plates is formed to perform a heat exchange.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2008-0051931, filed on Jun. 3, 2008, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to a heat exchanger, and more particularly, to a heat exchanger in which a channel type is changed into a fin structure to increase a heat transfer area, and the fin is formed into an airfoil shape to minimize a pressure drop due to the fin structure, thereby increasing a heat flowing performance.[0004]2. Description of the Related Art[0005]In the Republic of Korea, with an economical and social change due to a switchover to a highly industrialized society, energy consumption and emission of greenhouse gases such as carbon dioxide have been rapidly increased. Currently, advanced countries have strongly requested that the Republic of Korea, that is, one of...

AI Technical Summary

Benefits of technology

[0017]An aspect of the present invention provides a heat exchanger that may prevent a pressure drop while increasing a thermal efficiency regardless of a size of a channel.

[0018]An aspect of the present invention provides a heat exchanger that may change a disposition of a heat transfer fin to prevent a pressure drop of a fluid.

[0019]An aspect of the present invention provides a heat exchanger that may minimize an energy loss.

[0020]An aspect to the present invention provides a heat exchanger that may minimize a pressure drop, and enable a heat exchange fluid to flow using relatively less power of a pump, thereby reducing an installation cost and operation cost.

Problems solved by technology

The active method in which a pulsation is applied to a working fluid or an additive is applied to a fluid may be effective in all flowing areas, however, may be restrictively used because separate equipment is additionally needed, and energy requiring for driving the separate equipment is required to be supplied.

However, the conventional heat exchanger has problems which will be described in detail as below.

First, a pressure drop may significantly increase within the heat exchanger due to a reduction in the size of the fluid channel.

Third, an energy loss may occur due to the above-mentioned pressure drop, the vortex, and a swirl.

Fourth, a power of a pump may increase when replenishing the pressure drop, and an installation cost or operation cost may increase as a result.
