Description

Heat exchanger and heating device having it {Heat Exchanger and heating device having the same}

The present invention relates to a heat exchanger, and more particularly to a heat exchanger for controlling the temperature of the fluid and a heating apparatus having the same.

Conventional cold and hot water purifier for heating or cooling water is provided with a cold water tank with a predetermined cooling means, and a hot water tank equipped with a predetermined heating means in order to be able to use cold water or hot water at any time to provide cold water and hot water. By storing the water so that cold water and hot water can be used whenever necessary.

Therefore, the user continuously consumes power to maintain the water at a constant temperature even when the user is not using it, and since the cold water tank and the hot water tank are respectively built in the body, there is a problem in miniaturizing the cold / hot water purifier. have.

In addition, if the water contained in the hot water tank is maintained for a long time, the scale (aka time scale) is pinched in the hot water tank, there is a problem that the contamination of water due to the generation of foreign matters as well as the generation of harmful bacteria in these things.

Accordingly, in recent years, water purifiers that can heat or cool the heat energy instantaneously through energy sources have been developed, but this also has a certain time until the user reaches the desired temperature in the instantaneous heating and cooling of water. There is a problem that this may be consumed or may not reach the desired temperature desired by the user.

It is an object of the present invention to provide a heat exchanger and a heating device having the same that can be reached, heated and / or cooled more quickly by the flow path is formed in a spiral surrounding the heat exchanger in order to solve the above problems. There is.
