摘要： Radiator caps (266) and radiator tubes (211) are heat brazed with an ingot Z of a sacrificial material being disposed in the interior of a radiator tank main body (234), whereby, as the ingot Z of the sacrificial material is heated while being surrounded by the radiator tank main body (234), the evaporated sacrificial material is allowed to adhere to internal surfaces of the radiator tank main body (234) relatively uniformly, the sacrificial material so adhering to the internal surfaces being then allowed to be radiated into aluminum constituting the radiator tank main body (234) to thereby form an alloy layer (a corrosion preventing layer) containing therein the sacrificial material heavily on the internal surface of the radiator tank main body (234).

摘要： Two heat exchangers, such as a condenser for cooling refrigerant circulating in an air-conditioner and a radiator for cooling coolant in an internal combustion engine, are combined into a single unit. Both heat exchangers are overlapped in an airflow direction of cooling air. Each heat exchanger has a similar structure composed of a core having plural tubes and fins and a pair of header tanks connected to both ends of the tubes. Two heat exchanges are combined by a side plate disposed on the upper side thereof. The openings of both header tanks are closed with separately formed tank caps and are connected to the side plate through the tank caps. Direct heat transfer from one header tank to the other header tank, e.g., from the radiator tank to the condenser tank, is prevented because both header tanks are connected to the side plate through separate tank caps, thus achieving a high heat radiation capacity in the compound heat exchanger.

摘要： A double heat exchanger for a vehicle air conditioner has a first radiator for cooling engine coolant, a second radiator for cooling electronic-parts coolant for cooling electronic parts of the vehicle and a condenser disposed at an upstream air side of the first and second radiators. The condenser has a condenser core and a cooler through which refrigerant discharged from the condenser core flows. The second radiator is disposed opposite the cooler so that air having passed through the cooler passes through the second radiator. Therefore, a difference between a temperature of air passing through the second radiator and a temperature of electronic-parts coolant flowing through the second radiator is increased, and electronic-parts coolant is sufficiently cooled. As a result, the electronic parts are sufficiently cooled without increasing a size of the second radiator.

摘要： Waved uneven portions (112f, 122f) are formed on the protrusion portions (112e, 122e) of the fins (112, 122) protruded from an end of the tubes (111, 121) in the width direction of the tube without cutting part of the protrusion portions (112e, 122e) to increase the surface area of the fins (112, 122). As a result, the surface area of the protrusion portions (112e, 122e) may be increased without decreasing the thermal conductive area extending to the end of the protrusion portions (112e, 122e), and thereby a sufficient amount of heat may be conducted especially to the protrusion portions (112e, 122e), with decreasing airflow resistance, and an improvement in radiation ability appropriate to the increase of radiation area may, accordingly, be achieved.

摘要： A heat exchanger has plural tubes and a header tank communicating with each tube. The tank has an opening through which coolant is introduced, and an elevated portion formed in the vicinity of the opening by elevating a wall of the tank outwardly, so that a dimension of the tank including the elevated portion becomes larger than a dimension of the tank excluding the elevated portion in a direction perpendicular to a longitudinal direction of the tank. As a result, a volume and a sectional area of the tank in the vicinity of the opening are increased, thereby decreasing pressure loss of coolant flowing into the tank. Therefore, even when a size of the tank is reduced to reduce a size of the heat exchanger, pressure loss of coolant flowing into the tank is restricted from increasing.

摘要： A filler neck is connected to a connection pipe attached to a pouring port of a header tank of a radiator. A radiator cap having a pressure valve and an overflow pipe connected to a reservoir are attached to the filler neck. The filler neck has a cylindrical portion which includes an annular pressure-valve sealing portion making contact with the pressure valve, an opening formed inside an inner diameter of the pressure-valve sealing portion to communicate with the connection pipe and an opening peripheral portion formed along a periphery of the opening. The opening peripheral portion is disposed above a lower end of the overflow pipe. The filler neck is formed by pressing a metal plate. Therefore, the filler neck made of metal is readily formed into a shape substantially equal to that of a resin filler neck.

摘要： A double heat exchanger includes a condenser having a condenser core and a condenser header tank, and a radiator having a radiator core and a radiator header tank. The condenser header tank is composed of a core plate having clamping portions and a tank portion having protruding portions. The protruding portions of the tank portion are clamped by the clamping portions of the core plate so that the tank portion is connected to the core plate in the condenser header tank. The protruding portions of the condenser header tank contacts the radiator header tank, thereby preventing the condenser and radiator header tanks from being inclined toward each other. Therefore, the condenser and radiator header tanks contact and are brazed to each other in a relatively small area. As a result, heat conduction from the radiator to the condenser is prevented, and heat exchange performance of the condenser can be improved.

摘要： A radiator includes a core portion, a header tank, a side plate attached to the core portion and a bracket through which the radiator is mounted to a vehicle. The bracket is separately formed from the header tank, and is connected to the side plate through a bolt. As a result, the radiator is readily mounted to a vehicle of a different model by only changing an attachment position of the bracket to the radiator, without modifying the header tank. Further, the bracket includes a coolant receiving portion disposed to face a drain outlet of the header tank with a predetermined gap therebetween. Therefore, coolant discharged from the header tank collides with the coolant receiving portion to reduce its dynamic pressure. As a result, coolant drained from the radiator is restricted from being scattered.

摘要： In a double heat exchanger having a condenser core and a radiator core, a protrusion is provided on a condenser header tank which contacts a radiator header tank so that a clearance between the condenser header tank and the radiator header tank around the protrusion is in a range of 0.5 mm-1.5 mm. Further, a coating-removing restriction material such as magnesium for restricting the removal of an oxidation coating formed on the surface of a brazing material is added to one of the contact areas of the protrusion and the contact area of the condenser header tank. Thus, it can prevent brazing material from being collected in the contact areas of the protrusion and the condenser header tank by a capillary phenomenon during brazing. Accordingly, the heat-transmitting area between the radiator header tank and the condenser header tank is not increased, and the heat-radiating capacity of the condenser core is increased.

摘要： In a double heat exchange, a radiator and a condenser are integrated through a side plate for reinforcing the radiator and the condenser, and a longitudinal dimension of condenser tubes is made smaller than a longitudinal dimension of radiator tubes. Therefore, a core area of the condenser becomes smaller than that of the radiator. Thus, heat-exchanging capacity of the condenser is restricted from being increased more than a necessary capacity, and size and performance of the double heat exchanger are restricted from being increased more than necessary conditions.
