摘要： The invention relates to layered evaporators for use in motor vehicle air conditioners or the like, layered heat exchangers for providing such evaporators, and refrigeration cycle systems comprising the evaporator. At a specified intermediate portion of the heat exchanger with respect to the direction of juxtaposition of intermediate plates, a flat metal plate is interposed between one pair of intermediate metal plates providing a flat tube portion, or between two adjacent flat tube portions. The flat metal plate has a partition portion for blocking the passage of a fluid, a fluid passing hole for permitting passage of the fluid and an uneven flow preventing guide protuberance at an edge portion around the fluid passing hole.The flat plate of very simple structure is used according to the invention as the plate having a partition for providing heat exchanger core passes. This permits use of a simlified plate die of low cost and makes it possible to provide a fluid circuit core having varying pass patterns, and made from a reduced number of components by a simplified assembling procedure which can be automated. The flat plate used further makes it possible to intentionally control the flow of fluid to preclude the occurrence of an uneven flow in the pass and to achieve improved perforamce. The concentration of stress due to the internal pressure of the fluid at the location where the fluid flow is turned is attenuated to give increased pressure resistance to the turn portion and to effectively prevent the break of tank side wall. The heat exchanger is made from metal plates of reduced thickness for a cost reduction and an improvement in heat exchange efficiency.
摘要翻译：本发明涉及用于机动车辆空调等的分层蒸发器，用于提供这种蒸发器的分层式热交换器，以及包括蒸发器的制冷循环系统。在热交换器的相对于中间板的并置方向的特定中间部分处，将平的金属板介于提供扁平管部分的一对中间金属板之间或两个相邻的扁平管部分之间。平板金属板具有用于阻止流体通过的分隔部分，用于允许流体通过的流体通过孔和在流体通过孔周围的边缘部分处的不均匀流动防止引导突起。根据本发明，使用非常简单结构的平板，因为板具有用于提供热交换器芯通道的隔板。这允许使用低成本的模拟板模，并且使得可以提供具有变化的通过图案的流体回路芯，并且可以通过可以自动化的简化的组装过程由减少数量的部件制成。进一步使用的平板使得有可能有意地控制流体的流动以排除通过中不均匀流动的发生并且实现改进的穿孔。由于流体在流体流动的位置处的内部压力引起的应力集中受到衰减，从而对转弯部分的耐压性提高，并且有效地防止了箱侧壁的破裂。热交换器由厚度减小的金属板制成，以降低成本并提高热交换效率。
