    • The invention relates to heat exchangers for use in motor vehicles or for industrial use, for example, to heat exchangers for use as evaporators, condensers, oil coolers, intercoolers, heater cores, etc. The invention provides a heat exchanger comprising pairs of plates with each plate of the pair having formed on one side thereof a peripheral ridge, central ridge and channel dividing U-shaped ridges which are formed by forging or cutting. Each pair of plates are fitted together and joined, with channel recesses thereof opposed to each other to form a flat tube and a plurality of U-shaped divided fluid passageways in a U-shaped fluid channel inside the tube. Each pair of adjacent flat tubes are joined by spectacle-shaped header members interposed between the upper ends of the tubes and each comprising a front and a rear fluid passing tube portion and a connecting portion therebetween to provide a front and a rear header in communication with the upper ends of the flat tubes. The flat tubes have a reduced front-to-rear width, diminished wall thickness (thinner layers) and increased heat transfer efficiency to provide a heat exchanger which achieves a higher heat transfer efficiency and greatly improved heat exchange performance.
    • 本发明涉及用于机动车辆或工业用途的热交换器,例如用作蒸发器,冷凝器,油冷却器,中间冷却器,加热器芯等的热交换器。本发明提供了一种热交换器,其包括成对的具有 该对中的每个板的一侧形成有通过锻造或切割形成的外周脊,中心脊和通道分割的U形脊。 每对板被安装在一起并连接,其通道凹槽彼此相对以在管内的U形流体通道中形成扁平管和多个U形分开的流体通道。 每对相邻的扁平管通过插入在管的上端之间的眼镜状的头部构件连接,并且每个包括前后流体通过管部分和它们之间的连接部分,以提供与前部和后部头部连通的前部和后部头部 扁平管的上端。 扁平管具有减小的前后宽度,减小的壁厚(较薄层)和增加的传热效率,以提供实现更高传热效率和大大改善的热交换性能的热交换器。
