    • A heat exchanger, wherein an oil cooler unit in the state of preventing heat exchange cores (110) from falling off from a casing (120) is assembled temporarily to first and second plates (130, 140) and, after the oil cooler unit is immersed in flux to coat it with the flux, a bearing surface plate (150) is assembled to the second plate (140) and these plates are brazed to each other, whereby, because the thickness of the flux on the bearing surface plate (150) can be extremely reduced after the brazing is completed, a specified surface roughness can be assured on the bearing surface plate (150) even after the brazing while a man-hour required for flux coating is reduced.

    • Prior art exchanger cores (10) have been expensive to produce and have too often had poorly heat conductive joining of the liquid circulating tubes (12) to the cooling fins (14). Herein, the tube (12) is fitted into holes (28) in the fins (14) with a small gap (42 or 44) between a portion (20, 22) of the tube (12) and the hole (28). Solder sources (38) e.g., sheets (38) having holes (40) therethrough which generally match the holes (28) in the fins (14), are positioned between some of the fins (14) with the tubes (12) fitting in the holes (40) in the solder sheets (38). The entire assembly (50) is heated with the tubes (12) being held generally vertically. As the solder sheets (38) melt, solder flows through the gap (42 or 44) wetting not only the fin (14) above which it sits, but also lower fins (14). Capillary action leads to solder wetting the entire junction between each fin (14) and each tube (12). Good solder joints having excellent heat conducting properties are produced.
