Description

The present invention relates to a heat exchanger, and more particularly, to a heat exchanger in which the heat exchange efficiency is higher than the conventional one.

Currently, heat exchangers are widely applied to various types of equipment and systems (for example, automated industrial equipment, air-conditioning equipment, cooling systems, etc.), and are water-cooled heat exchangers and air-cooled heat exchangers. The water-cooled heat exchanger is classified into a shell type heat exchanger and a wound tube type heat exchanger. In order to solve such a problem, the applicant of the present application has applied Taiwan Patent No. 095208891 to reduce the heat exchange efficiency due to the adhering of dust, resulting in a large loss of energy and increasing the running cost. The "heat exchanger with cleaning device" is proposed, and the above-mentioned "heat exchanger with cleaning device" simplifies the cleaning means, improves the heat dissipation effect, and can reduce energy loss. .
