    • 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.
    • 多层型热交换器由一排平行的扁平管形成,每排扁平管具有在扁平管的宽度方向上隔开并且邻近其一端设置的槽部。 每个管在其中限定有用于从一个罐部朝向管的另一端延伸的传热流体的通道,然后转向另一个罐部分。 扁平管被堆叠,使得罐部分彼此流体流动连通地连接在一起。 除了罐部分之外的每个相邻的一对管的部分间隔开以容纳波纹状翅片。 每个管由两个压接在一起的压芯芯板形成,以在管中形成通道。 每个相邻的一对管的两个相邻的芯板具有延伸到彼此或彼此接合或一体地连接在一起的弯曲端部,以相互间隔的关系支撑相邻管的另一端,以适应它们之间的翅片。
