摘要： A method of manufacturing a brazed pipe comprises steps A to D. In the step A, on an upper surface of the right-hand side edge portion of a material plate 20 having a brazing material layer over opposite surfaces thereof, a first slant surface 21 is formed such that it inclines from the upper side toward the lower side while approaching the right end, and a first flat surface 22 is formed between the first slant surface 21 and the lower surface. In the step B, on a lower surface of the left-hand side edge portion of the material plate 20, a second slant surface 24 is formed such that it inclines from the lower side toward the upper side while approaching the left end, and a second flat surface 25 is formed between the second slant surface 24 and the lower surface. In the step C, the material plate 20 is formed into a tubular shape such that the slant surfaces 21 and 24 are in surface contact with each other, and the flat surfaces 22 and 25 abut against each other, whereby a brazed-pipe tubular body 34 is obtained. In the step D, the slant surfaces 21 and 24 and the flat surfaces 22 and 25 of the opposite side edge portions of the material plate 20 are respectively brazed together by making use of the brazing material layer of the material plate 20. According to the method of the present invention, a brazed pipe which has no step on the outer surface can be provided.

摘要： An intermediate heat exchanger 10 includes a double tube 11 and a liquid reservoir 14. The double tube 11 has an outer tube 15 and an inner tube 16 disposed inside the outer tube 15 with a clearance formed therebetween. The clearance between the outer tube 15 and the inner tube serves as a high-temperature-side refrigerant passage 12, through which refrigerant of high pressure flowing out of a condenser flows, and the interior of the inner tube 16 serves as a low-temperature-side refrigerant passage 13, through which refrigerant of low pressure flowing out of an evaporator flows. The liquid reservoir 14, which communicates with the high-temperature-side refrigerant passage 12 of the double tube 11, stores the refrigerant of high pressure flowing out of the condenser before the pressure of the refrigerant is reduced by a pressure reducer, and separate liquid-phase refrigerant and gas-phase refrigerant. The outer tube 15 of the double tube 11 has a refrigerant inlet 17 and a refrigerant outlet 18 communicating with the high-temperature-side refrigerant passage 12. At an intermediate position between the refrigerant inlet 17 and the refrigerant outlet 18, refrigerant flows from the high-temperature-side refrigerant passage 12 of the double tube 11 into the liquid reservoir 14, and returns from the liquid reservoir 14 to the high-temperature-side refrigerant passage 12.

摘要： A flat tube includes a pair of upper and lower walls opposed to each other, two side walls interconnecting the upper and lower walls at left and right opposite side edges thereof, and a covering wall provided over the outer surface of the left side wall and brazed to the left side wall. The left side wall is made from a side wall forming portion projecting downward from the upper wall integrally therewith and a side wall forming portion projecting upward from the lower wall integrally therewith by brazing these portions as butted against each other. The covering wall is made by folding a covering wall forming portion formed by extending one side edge of the upper wall. The left side wall including the wall forming portion of the upper wall and the wall forming portion of the lower wall can be protected.
