摘要： A tapered section and a flange section which constitute reinforcements are provided on mounting members to which a blower (fan shroud) is to be attached. The reinforcements are provided on the sides of the reinforcements which are in contact with a longer side wall surface of a rectangular tank. According to this structure, it is possible to prevent the longer side wall surface from deforming, while mitigating the concentration of stress to the joint portions between the mounting members and the longer side wall surface. Therefore, the mechanical strength, reliability and durability of the header tank can be improved without increasing the mass (weight) and production cost of the radiator.

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.

摘要： According to the present invention, a pin-disposed portion where a pin member for mounting a heat exchanger on a vehicle is disposed is structured such that an inner edge shape of a cross section of the pin-disposed portion draws a four-sided closed curved line. The pin member passes through an inner space of the pin-disposed portion and is connected to the pin-disposed portion at plural positions. In this way, the pin-disposed portion constructs a shell structure which is superior in a mechanical strength. Further, because the pin member is connected to the pin-disposed portion at plural positions while passing through the space, the shell structure of the pin-disposed portion can be made more rigid.

摘要： A corrugated fin for a double heat exchanger having a condenser and a radiator integrally includes a condenser fin and a radiator fin. Each of the condenser fin and the radiator fin has plural bent portions and plural flat portions each of which connects adjacent bent portions. A louver-forming processing amount of the flat portion of the condenser fin is set smaller than that of the flat portion of the radiator fin. Plural dimple-shaped plastically deformed portions are formed in the flat portion of the condenser fin, so that a whole processing amount of the condenser fin becomes substantially equal to that of the radiator fin. As a result, a radius of curvature of each bent portion of the condenser fin is substantially equal to that of the radiator fin, and the integrated fin is restricted from being deformed.

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 fan apparatus for preventing the occurrence of a burble on a surface of a blade while the resistance to air flow into the fan is increased and the generated noise is kept small. Each fan of the blade has a first area which extends from the bottom portion of the blade to the intermediate portion and a second area from the intermediate portion of the blade to the top portion of the blade. The setting angle of the blade is a first, predetermined angle at the first area of the blade but is increased at the second area of the blade. Further, the chord length of the blade gradually increases from the bottom to the top of the blade. Additionally, a first wing axis of the blade in the first area is not parallel to a second wing axis of the blade at the second area but, rather, the second wing axis is inclined towards the rotational direction of the fan apparatus. Finally, the profile of the blade of the invention is formed so that the profile at the first area is perpendicular to the first wing axis and the profile at the second area is perpendicular to the second wing axis. With such a structure, a pressure distribution along the wing chord is substantially the same at the first area and the pressure distribution along the wing chord at the second area is gradually increased so that the shape of the pressure distribution is similar to that of the first area.

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.
