PURPOSE: A heat exchanger is provided to enhance the inner pressure of a header tank by a separating wall which separates an inner penetrating hole from an outer groove and is formed on a tank body. CONSTITUTION: A heat exchanger comprises a tube(1100), a fin, a tank body(1310), and a tank sheet(1320). The fin is installed between the tubes. The tank body comprises an inner penetrating hole(1311), an outer groove(1312), and a body slot(1313). The inner penetrating hole is formed in the tank body in a longitudinal direction of the tank body. The outer groove is formed on the outer circumference of the tank body in a longitudinal direction. The outer groove is separated from the inner penetrating hole. The body slot communicates one end of the tube and the inner penetrating hole and the outer groove, respectively. The tank sheet surrounds the outer groove, is connected to the outer circumference of the tank body and comprises a sheet slot(1323). The sheet slot is connected to the body slot so that one end of the tube is inserted into the body slot.
