Patent ID: 6988541

Claim:
An oil-cooler-equipped radiator comprising: a radiator; a tank provided in the radiator; and an oil cooler that is accommodated in the tank of the radiator and that has a heat exchanger, the heat exchanger comprising: a plurality of stacked element units that communicate with each other, a pair of fixed tube plates that are in communication with the outermost element units of the heat exchanger, and a pair of connecting pipes that are disposed through corresponding openings in a side wall of the tank and through corresponding openings in both end portions in the longitudinal direction of one of the tube plates, wherein each of the connecting pipes is formed with a blocking flange that is wide enough to block the corresponding opening of the tank and that is disposed on an outer surface of the corresponding connecting pipe at a mid portion of the corresponding connecting pipe such that the blocking flange is in contact with the outer surface of the side wall of the tank, wherein the width of each opening in the side wall of the tank is larger than at least the outer diameter of the corresponding connecting pipe in the longitudinal direction of the oil cooler, wherein, before brazing the oil-cooler-equipped radiator, which is brazed while the oil cooler is accommodated in the tank of the radiator in a state in which respective circular interposed members are correspondingly disposed between outer edge portions of the openings of the tube plate and inner edge portions of the openings of the tank, the connecting pipes are inserted through the corresponding openings of the tank so as to temporarily assemble the connecting pipes in the corresponding openings of the tube plate, so that both of the blocking flanges are retained while being in contact with the outer surface of the side wall of the and the oil cooler is held by holding plates each having bent portions so as to have a substantially U-shaped cross-section, and wherein top portions of side pieces of each holding plate are disposed through the side wall of the tank and are bent, so that the oil cooler is retained by being sandwiched between middle supporter pieces of the respective holding plates and the side wall of the tank in the stacking direction of the element units while being movable in the longitudinal direction of the oil cooler with respect to the side wall of the tank.
