Abstract (en)
A heat exchanger of the present invention includes: a case in which a space is formed; a tope cover coupled to the top of the case; a lower cover coupled to the bottom of the case; a cooling water inflow pipe guiding cooling water flowing into the space and having an exit end through which cooling water comes out into the space; a tube through which a refrigerant that exchanges heat with the cooling water passes; and a cooling water discharge pipe guiding the cooling water discharged from the space and having an inlet end that the cooling water enters, in which the tube has a spiral pipe portion positioned in the space and spirally wound, the inlet end is positioned to be spaced from the top cover under the top cover, the height of the inlet end is larger than the height of the upper end of the spiral pipe portion, and the height between the exit end and the lower cover is smaller than the height between the inlet end and the lower cover; therefore, it is possible to achieve a compact heat exchanger while minimizing the installation space and the cooling water can exchange heat with the spiral pipe portion of the tube as much as possible.
