摘要： A tube inside passage height (Tr) is set within a range of 0.35–0.8 mm. Thereby, sum of radiation performance reduction due to pressure loss inside tube and radiation performance reduction due to air flow resistance is reduced, thereby attaining high radiation performance. Especially, when the tube inside passage height (Tr) is set within a range of 0.5–0.7 mm, the radiation performance is further improved.

摘要： In a receiver-integrated condenser, a super-cooling portion for cooling liquid refrigerant from a receiving unit is disposed between first and second condensing portions in a core portion in a vertical direction. Therefore, in an engine-idling, even when high-temperature air having passed through the receiver-integrated condenser is introduced again toward an upstream air side of the receiver-integrated condenser through a lower side of the receiver-integrated condenser, the high-temperature air is not introduced toward the arrangement position of said super-cooling portion, because the super-cooling portion is positioned at an upper side from the second condensing portion. Thus, super-cooling performance of refrigerant in the super-cooling portion of the core portion is prevented from being decreased even in the engine idling.

摘要： A heat exchanger has a header tank, plural tubes through which refrigerant flows and a connector for connecting the tank to a pipe. The header tank has a pair of protruding portions protruding from an outer surface of the header tank and integrally formed with the header tank. When the connector is bonded to the tank by brazing, the connector is disposed between the protruding portions, and each of the protruding portions is bent toward the other at a protruding end thereof by plastic deformation. As a result, the connector is clamped by the protruding portions and is fastened to the header tank. Thus, the connector is readily and tentatively fastened to the header tank before bonded to the header tank by brazing.
摘要翻译： 热交换器具有集水箱，制冷剂流过的多个管和用于将罐连接到管的连接器。 集水箱具有从集水箱的外表面突出并与集水箱一体形成的一对突出部。 当连接器通过钎焊接合到罐时，连接器设置在突出部分之间，并且每个突出部分在其突出端处通过塑性变形而朝向另一个弯曲。 结果，连接器被突出部分夹紧并被固定到集水箱。 因此，在通过钎焊粘合到集水箱之前，连接器容易且暂时地紧固到集水箱。

摘要： According to the present invention, in a corrugated fin type heat exchanger including a core portion having a plurality of flat tubes disposed in parallel relation with regard to a flow direction of air and at least one corrugated fin disposed between each pair of the flat tubes, a height of a flow space within the flat tube is in a range of 0.6-1.2 mm, a height of the corrugated fin is in a range of 3-6 mm, and a ratio (St/W.times.D) of the cross-sectional area (W.times.D) expressed by an overall width dimension (W) and a thickness dimension (D) of the core portion to a total cross-sectional flow passage area (St) of the plurality of flat tubes is set to a range of 0.07-0.24 according to the height of the flow space of the flat tube and the height of the corrugated fin. In this way, it is possible to reduce the Reynold's number of the flow passages within the flat tubes to maintain a constant region irrespective of the variation in the hot water flow quantity, thereby reducing the variation in the water side heat transfer rate.

摘要： A heat exchanger includes a tank and a base plate, and each of the tank and the base plate is formed in a box shape having a U-shaped cross-section. The tank is connected to the base plate to close an end portion of an opening side of the tank using the base plate. Protrusion portions are provided inside a folded portion of the base plate in a lateral direction to be opposite to connection portions of first and second folded portions of the tank. Further, ribs are provided in the folded portion of the base plate in the lateral direction to increase stiffness of the base plate in a longitudinal direction thereof. Thus, connection portions of the tank and the base plate can be securely brazed.

摘要： A heat exchanger reduces a production of scrap portions and does not use a claw bending process at a time of forming a tank and a base plate. Each of the tank and the base plate is formed in a box shape having a U-shaped cross-section. The tank is joined to the base plate to close an end portion of an opening side of the tank using the base plate. A tube is inserted into a hole made at the base plate and fixed thereat in such a manner that the tube communicates with an inside of the tank. Each of the tank and the base plate is formed by folding an unfolded metal plate in which the box shape having the U-shaped cross section is in an unfolded state and joining a folded portion of the unfolded metal plate by brazing. According to the above configuration, the tank and the base plate can be structured by folding unfolded plates and by connecting the folded portions.
