A heat exchanger is provided. The heat exchanger may include a case in which a space is formed; a top cover coupled to a top of the case; a lower cover coupled to a bottom of the case; a first pipe that guides a first fluid to flow into the space and having an exit end, through which first fluid may come out into the space; a tube, through which a second fluid, which exchanges heat with the first fluid, may pass; and a second pipe that guides the first fluid discharged from the space and having an inlet end through which the first fluid may enter. The tube may have a spiral pipe portion positioned in the space and spirally wound. The inlet end may be positioned to be spaced from the top cover under the top cover. A height of the inlet end may be larger than a height of an upper end of the spiral pipe portion, and a height between an exit end and the lower cover may be smaller than a height between the inlet end and the lower cover. With this structure, it is possible to achieve a compact heat exchanger, while minimizing an installation space, and the first fluid may exchange heat with the spiral pipe portion of the tube as much as possible. |
