A radiator is provided to improve heat transfer performance by making the mass flow and pressure falling value of cooling water, circulating in a first circulation route of cooling water and a second circulation route of cooling water, identical. A plurality of tubes(20) are arranged abreast and forms into a heat exchange media circulation route. A plurality of heat radiation fins are interposed among a plurality of tubes. A header has a plurality of tube injection holes. A header tank consists of a tank forming into a heat exchange media flow route. The both end parts of the tube are inserted into the tube injection hole and the both end parts are fixed. The tank is combined with the top of the header. The tube is segmented into a first circulation route of cooling water(21a) of an air inlet and a second circulation route of cooling water(21b) of an air outlet with a partition equipped inside. |
