摘要： In a condenser of a refrigerant cycle, a throttle portion is provided at a predetermined position in one of first and second header tanks to decompress refrigerant while refrigerant meanderingly flows within the one of the first and second header tanks. Therefore, refrigerant from the throttle portion is sufficiently mixed with refrigerant directly flowing from tubes into a downstream space of the throttle portion in the one of the first and second header tanks. Accordingly, even when gas refrigerant is directly introduced from a part of the tubes directly into the lower downstream space, the gas refrigerant can be effectively heat-exchanged with the refrigerant flowing from the throttle portion. As a result, it can restrict refrigerant from being discharged from the condenser in a gas-liquid two-phase state.

摘要： A refrigerant cycle system includes a condenser having a condensation portion for condensing refrigerant discharged from a compressor, and a receiver for separating refrigerant from the condensation portion into gas refrigerant and liquid refrigerant, and for storing the liquid refrigerant. In this system, refrigerant from the condensation portion flows into the receiver through a first communication hole, and liquid refrigerant in the receiver is discharged through a second communication hole in which a pressure loss is generated. Further, gas refrigerant at an upper side in the receiver is discharged to a downstream side of the second communication hole through a gas bypass pipe.

摘要： A heat exchanger such as a condenser for use in an automotive air-conditioner includes a core unit having a plurality of laminated tubes and fins. Brackets for mounting the heat exchanger on a vehicle are connected to U-shaped side plate disposed on an outside of the core unit. After components constituting the core unit including the side plate are all connected to one another by brazing, the brackets are connected to the side plate via mounting members made of rubber by staking sidewalls of the U-shaped side plate. Since the brackets are connected to the heat exchanger by staking after the heat exchanger is completed, the heat exchanger is easily brazed and the number and positions of the brackets on the side plate can be arbitrarily selected.

摘要： A bracket portion and a caulking pawl portion are provided on a tank cap closing an end portion of a first refrigerant header tank of an evaporator. Brazing is carried out in a state where the pawl portion is caulked and provisionally fixed to side plates by the pawl portion. As the evaporator and a radiator for electric components are coupled through the bracket portion, the coupling distance can be reduced and a suitable fastening strength between the evaporator and the radiator for electric components can be secured.

摘要： A heat exchanger includes left and right header tanks disposed in parallel; top and bottom side plates that couple respectively both ends of the pair of the header tanks; a first plurality of tubes connected between the pair of the header tanks at both ends that are disposed in a region nearer the bottom side plate as a condenser; and a second plurality of tubes that are disposed in a region nearer the top side plate as an oil cooler. Each tube in the second tubes has a cross-sectional shape identical to that of each tube in the first tubes and the top side plate is formed to have a squared U-shaped cross section so that a return pipe communicating with the second tubes can be disposed along a groove having the squared U-shaped cross section of the top side plate.

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.
