The present invention provides a heat exchanger for cooling an electric element of a vehicle, comprising: a cooling unit including a first tube with a rectangular parallelepiped shape disposed above an electric element and having a flow path formed therein, and a second tube with a rectangular parallelepiped shape disposed below the electric element and having a flow path formed therein; an inlet and outlet part including an inlet part coupled to one side of the first tube and introducing cooling water into a flow path, and an outlet part coupled to one side of the second tube and discharging the cooling water; and a circulation part including a pair of communication parts coupled to the other sides of the first tube and the second tube, respectively, and a pair of connection parts disposed between the pair of communication parts such that the pair of communication parts communicate with each other, wherein the circulation part is formed to be deformable in a direction in which the opposing surfaces of the first tube and the second tube come close to each other when pressurized. The present invention can prevent twisting when brazing welding is performed. 본 발명은, 전기소자의 상측에 배치되며 내부에 유로가 형성되는 직육면체 형상의 제1 튜브와, 전기소자의 하측에 배치되며 내부에 유로가 형성되는 직육면체 형상의 제2 튜브를 포함하는 냉각부; 상기 제1 튜브의 일측에 체결되어 냉각수를 유로로 유입시키는 유입부와, 상기 제2 튜브의 일측에 체결되어 냉각수를 배출시키는 배출부를 포함하는 유출입부; 및 상기 제1 튜브와 제2 튜브의 타측에 각각 체결되는 한 쌍의 연통부와, 상기 한 쌍의 연통부가 상호 연통되도록 상기 한 쌍의 연통부 사이에 각각 배치되는 한 쌍의 연결부를 포함하는 순환부;를 포함하며, 상기 순환부는 가압시 상기 제1 튜브와 제2 튜브의 대향면을 상호 근접시키는 방향으로 변형될 수 있도록 형성되는 차량의 전기소자 냉각용 열교환기를 제공한다.
