Problems solved by technology
Firstly, if corrosion occurs in the heat exchanger coil 10, a corrosion layer is generated in the heat exchanger coil 10. This may lower a heat exchange performance, and may severely shorten the lifespan of the heat exchanger coil 10. This may cause the heat exchanger coil 10 to be replaced by a new one with a predetermined period. Especially, in a case that a heat transfer medium inside the heat exchanger coil 10 is discharged for prevention of freezing in winter, the inside of the heat exchanger coil 10 is open when discharging the heat transfer medium and re-filling a heat transfer medium. In this case, the inside of the heat exchanger coil 10 may be drastically corroded due to reactions with oxygen. Accordingly, the inside of the heat exchanger coil 10 as well as the outside of the heat exchanger coil 10 has to be prevented from being corroded.
Since the heat exchanger applied to a cooling tower, etc. has a large capacity, it is not easy to maintain and repair the heat exchanger, and high costs are required to maintain and repair the heat exchanger.
However, the heat exchanger coil 10 having undergone zinc galvanizing and anticorrosion coating cannot undergo a welding process, a bending process, etc. for manufacture in a serpentine shape, due to damages of the zinc galvanizing and anticorrosion coating.
This may cause the conventional serpentine-type serviceable heat exchanger to be very vulnerable to corrosion.
However, the injection of the antifreeze solution and the anticorrosive agent may result in increase of initial investments costs, and periodic injections thereof may increase maintenance and repair costs.
Furthermore, when the antifreeze solution and the anticorrosive agent are replaced by new ones, waste materials may occur and the waste materials may result in environmental destruction.
This may cause drastic increases of initial investment costs and driving costs.

Abstract
A heat exchanger for a heat exchange operation such as sensible heat exchange, evaporation and condensation, and more particularly, a serpentine-type serviceable heat exchanger where a heat exchanger coil which guides a heat transfer medium for a heat exchange is formed in a serpentine shape, and a method for manufacturing the same. The serpentine-type serviceable heat exchanger includes a heat exchanger coil having a plurality of linear coils disposed in parallel, and a connection coil disposed between the two neighboring linear coils and fittedly-coupled to the linear coils such that a serpentine-type inner passage is formed as the linear coils are connected to each other by the connection coil; and a frame having an edge forming portion which forms an edge such that the heat exchanger coil is installed therein, and a supporting portion which supports the heat exchanger coil installed in an edge formed by the edge forming portion.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat exchanger for a heat exchange operation such as sensible heat exchange, evaporation and condensation, and more particularly, to a serpentine-type serviceable heat exchanger where a heat exchanger coil which guides a heat transfer medium for a heat exchange is formed in a serpentine shape, and a method for manufacturing the same.[0003]2. Background of the Invention[0004]A heat exchanger serves to heat or cool a heat transfer medium (e.g., cooling water, hot water, a refrigerant, etc.) by a heat exchange operation using air, water, etc. This heat exchanger is mainly applied not only to an air conditioner for home and a refrigerator, but also to a cooling tower which cools cooling water by heat-exchanging with outdoor air so that the cooling water used in a condenser for an industrial freezer can be re-used.[0005]The heat exchanger has various structures according to a usage purpose,...
