摘要： A plurality of first projections 113a are provided in a first side wall portion 111a of a grooved section 111 formed by bending part of a sheet-like workpiece to have a U-shaped cross-section, which projections extend away from a connecting portion (top) 111c. Since the first side wall portion 111a deforms to widen a groove width of the grooved section 111 due to spring-back, a tip end of the first projection 113a is first brought into contact with the inner wall 110a. Therefore, a reaction force against the compressive force is applied to the tip end of the first projection during the pre-assembly process. Since the tip end of the first projection 113a is not movable due to the contact with the inner wall 110a, a bending moment is applied to the first side wall portion 111a and the connecting portion 111c to reduce the groove width. Accordingly, as the compression progresses, the inserting section 112 is automatically rolled in the grooved section 111 to ensure secure brazing between the grooved section 111 and the inserting section 112.

摘要： A bracket (300) is coupled to tank caps (122, 222) of header tanks (120, 220), and the bracket (300) is separably attached to a radiator (200) and a condenser (100) by means of hooks (311, 312) and holes (female screw section) (331) for fixing bolts (330). Thereby, it is unnecessary to provide fixing means in a side plate (130, 230) for fixing the bracket (300) thereto. Accordingly, it is possible to reduce the size and the weight of the side plate (139, 230), and easily attach and detach the radiator (200) and the condenser (100) from a vehicle.

摘要： A condenser core portion carries out a heat exchange between refrigerant and air. The condenser core portion includes a plurality of condenser tubes through which the refrigerant flows and condenser fins disposed between each pair of adjacent condenser tubes. A radiator core portion is disposed in series with the condenser core portion in an external fluid flow direction with a predetermined clearance therebetween, to carry out a heat exchange between engine coolant and the air. The radiator core portion includes a plurality of radiator tubes through which the engine coolant flows and radiator fins disposed between each pair of adjacent radiator tubes. A connecting portion integrates each of condenser fins and radiator fins. The condenser fins disposed at an upper area of the condenser core portion introduce cooling performances more than the condenser fins disposed at a lower area thereof.

摘要： A heat exchanger has a flat tube (10) having a curved portion (13). A part of the curved portion (13) is formed by overlapping an outer rim (22) on an inner rim (21). The inner rim (21) has a small curvature region (102). The small curvature region (102) is inclined to a flat plate portion (11), and is defined by a radius larger than a difference between a half of a thickness of the flat tube (10) and a thickness of the outer rim (22). The small curvature region (102) is not beyond a center line (C1) in a thickness of the flat tube (10). The outer rim (22) extends beyond the center line (C1). The outer rim (22) has an end face (22a) placed on the small curvature region (102). The flat tube (10) has flared portions (15, 16) expanded at insertion holes (54).

摘要： A protruding portion protruding toward the outside a tank is formed on a core plate in a range corresponding to a straight portion of a flat tube inserted and joined to the core plate. Due to this structure, a joining portion of the tube to the core plate is three-dimensionally formed and a joining portion length is extended. Therefore, thermal stress generated in the tube can be diffused from the joining portion of the tube to the core plate.

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： The towel dispenser adapted to store and supply a towel of undeterminate length. At least one of the unused and used portions of the towel is stored in the form of a roll on a shaft. The towel dispenser includes a pair of side walls each having at least one elongated hole. The portion of the side wall defining the inner peripheral edge of the elongated hole is obliquely bent towards each respective other side wall so as to form a tab projecting towards the other side wall. Each end of the shaft is rotatably and slidably received in the respective elongated hole defined by the respective tab, in such a manner that each end of the shaft does not project beyond the plane of the associated side wall.

摘要： A plurality of angle portions 2c of the fins on an upstream side and those on a downstream side of an air flow are provided so as to be substantially symmetrical with each other. Due to this, bending forces are continuously exerted on a thin plate-like fin material in a direction where the bending deformation of the fin material is cancelled, during the fin forming process. Accordingly, when the angle portions 2c are formed it can be prevented in advance that the fin material 11 is deformed in a state where the repeated deformations of the fin material 11 are accumulated in the same direction.

摘要： A projection portion (145) protruding from a bottom surface 8141a) on a core portion side towards the center of the core portion (130) is formed in a core plate (140). A bond portion (142a) between a tube (132) and the core plate (140) is arranged closer to the center side of the core portion (130) than the bottom surface (141a) and at substantially the same position in a tube longitudinal direction X with respect to a push surface (143a) of a packing (150). Therefore, even when a load in a direction intersecting at right angles the tube longitudinal direction is applied to a formation portion of a fitting groove portion (143), the occurrence of a bending moment can be suppressed.
