    • A flat plate type heat exchanger or evaporator is disclosed for use in automobile air conditioning systems. The heat exchanger includes a set of stacked plate pairs having refrigerant fluid passageways extending laterally between the plates of each plate pair while the spaces between the plate pairs define air flow passageways having fins located therein. In one aspect, fluid inlet and outlet passages are formed when differently sized tubes in adjacent plate pairs are telescoped together and subsequently brazed together to form a high surface area, fluid tight joint. The resulting fluid tight joint formed between tubes in adjacent plate pairs exhibits greater rupture resistance than that formed with drawn cup assemblies currently in use. These refrigerant fluid inlet and outlet passageways are spaced inwardly from the edges of the evaporator and extend transversely through the stack, the inlet and outlet passages being in communication with the fluid passageways.
    • 公开了一种用于汽车空调系统的平板式换热器或蒸发器。 热交换器包括一组堆叠的板对,其具有在每个板对的板之间横向延伸的制冷剂流体通道,而板对之间的空间限定了具有位于其中的翅片的气流通道。 在一个方面,当相邻板对中的不同大小的管被伸缩在一起并随后钎焊在一起以形成高表面积的流体密封接头时,形成流体入口和出口通道。 在相邻板对中的管之间形成的所得流体紧密接头比当前使用的拉拔杯组件形成的抗断裂性更强。 这些制冷剂流体入口和出口通道与蒸发器的边缘向内间隔开并且横向延伸穿过堆叠,入口和出口通道与流体通道连通。
