Abstract
A multi-layer type heat exchanger is formed by a row of parallel flat tubes each having tank portions spaced widthwise of the flat tube and disposed adjacent to one end thereof. Each tube defines therein a passage for a heat transfer fluid extending from one tank portion towards the other end of the tube and is then turned to the other tank portion. The flat tubes are stacked such that the tank portions are connected together in fluid-flow communication with each other. The portions of each adjacent pair of tubes excepting the tank portions are spaced apart to accommodate a corrugated fin. Each tube is formed by two press-worked core plates soldered together to form the passage in the tube. Two adjacent core plates of each adjacent pair of tubes have bent end portions extending to and engaged with each other or integrally connected together to support the other ends of the adjacent tubes in spaced relationship to accommodate the fin therebetween.
