摘要： A heat exchanger includes reservoirs spaced apart from each other and a plurality of parallel heat transfer tubes fluidly connecting the reservoirs. An end portion of each heat transfer tube is connected to at least one of the reservoirs so that the end portion does not project into the interior of the reservoir. Thus, the dimension of the reservoir in the axial direction of the tubes and a proper volume of heat transfer medium may be minimized. Further, pressure loss can be reduced because there are no projecting tubes in the reservoirs to obstruct the flow of the heat transfer medium. Moreover, the strength of the connection between the tubes and the reservoirs can be increased because more contacting surface area is provided for making the connection, for example by brazing.

摘要： A heat exchanger includes upper and lower tanks, a plurality of parallel heat transfer tubes fluidly interconnected between the upper and lower tanks, a plurality of reinforcing members connecting an upper wall and a lower wall of the upper and lower tanks, and a communication path associated with each reinforcing member. The reinforcing members increase the strength of the tank walls against deformation due to the high pressure working fluid without increasing the thickness of the walls or increasing the spacing between the tubes. The communication path ensures efficient flow of a heat medium in the tanks.

摘要： A heat exchanger is provided with a first tank and a second tank. Heat transfer tubes are disposed between the tanks and are connected to the tanks to place the tanks in fluid communication. Either of the tanks may be divided into chambers by a partition. The partition has at least one portion which is oriented to be angularly offset from the direction of an air flow passing through the heat exchanger. The orientation of the partition permits the heat transfer tubes to be connected to the tanks in an arrangement so that no portion of the air flow can pass through the heat exchanger without striking at least one of the heat transfer tubes.

摘要： A heat exchanger includes a pair of substantially parallel header pipes and a plurality of substantially parallel tubes disposed between the pair of header pipes. Each tube defines a pair of end portions which are connected to the pair of header pipes. A plurality of rows of fins are provided along sides of the tubes. A pair of reinforcement members are provided along sides of each of the top and bottom rows of fins. Each of the pair of header pipes has a plurality of holes for inserting the end portions of the tubes to connect the tubes to each pipe of the pair of header pipes. At least one slit is formed on the end portions of each header pipe. The end portions of the reinforcement members extend through the slits to close the open ends of the header pipes. In one embodiment, each of the end portions of the reinforcement members extend through each header pipe through a pair of opposed slits and is bent to fix itself to the header pipe. The number of heat exchanger parts is thus reduced and the manufacture thereof is simplified.

摘要： A method of brazing a temporarily assembled heat exchanger includes the steps of spraying an ionized fluid such as water on one surface. A powdered electrostatically charged flux is blown onto the opposite surface of the heat exchanger. A portion of the powdered flux is attracted to the one surface by the ionized fluid. Therefore, the flux material is uniformly spread across the heat exchanger. Finally, the heat exchanger is heated and brazed.

摘要： A condenser for a refrigerant circuit including a compressor, a condenser, an expansion valve and an evaporator which are sequentially disposed is disclosed. The condenser includes a plurality of tubes having opposite first and second open ends, and a plurality of fins disposed between the plurality of tubes. First and second header pipes are fixedly disposed at the opposite ends respectively, and the open ends of the tubes are disposed in fluid communication with the interior of the header pipes. The first header pipe has an inlet which links the condenser to an external element of the circuit. The second header pipe has a first open end and a second closed end. An outlet element is disposed at the first open end of the second header pipe and links the condenser to an external element of the circuit. A pipe member is disposed in the second header. One open end of the pipe member is disposed near the closed end of the second header, and the other open end of the pipe member is disposed near the outlet. In operation, the refrigerant fluid which condenses in the condenser accumulates in an accumulating section and than flows out to the external fluid circuit from the second header exclusively through the pipe member. Since the condenser includes an accumulator section disposed therein, the need for a separate receiver element in the circuit is eliminated.

摘要： An air conditioner has air an duct defining an air path. Cooling and heating devices are provided in the air path, and the cooling and heating devices are disposed in parallel with respect to a longitudinal axis of the air duct. Switching means are provided at positions upstream and downstream of the parallel cooling and heating devices, respectively, for controlling air flow into, and air flow from, the cooling device or the heating device, or both. The size, e.g., the length of the air duct is reduced by the parallel disposition of the cooling and heating devices, thereby reducing the size of the entire air conditioner.

摘要： A method of manufacturing a heat exchanger includes a pair of tubular header pipes having a plurality of connection holes for heat exchanger tubes extended between the header pipes. A plurality of opposite corresponding cut portions are formed on both ends of a plate. The plate is bent into an almost tubular shape. The heat exchanger tubes are inserted into the opposite cut portions. The plate is further bent into a complete tubular shape, with the opposite cut portions forming completed connection holes. Thus, the connection holes are formed at desired positions of the heat exchanger and simultaneously, the tubes can be precisely and securely connected to the header pipes.
