Abstract
A heat exchanger is disclosed. Different cooling media are circulated in respective independent flow channels between the first heat-exchanging plate and the second heat-exchanging plate so as to perform heat exchange while preventing mixing between the different cooling media. A first guide of the first heat-exchanging plate and a second guide of the second heat-exchanging plate are layered to form an overlapping structure, and thus coupling capability and durability are improved when the first heat-exchanging plate and the second heat-exchanging plate are welded to each other. A discharge path is provided in order to detect internal leakage after welding between the first heat-exchanging plate and the second heat-exchanging plate, thereby making it possible to determine that there is malfunction in the heat exchanger based on the cooling media exposed from the discharge path when the cooling media leaks due to an internal defect.
