    • A laminate type heat exchanger includes a plurality of tubular elements each formed of a pair of generally flat stamped plates joined together in an abutting manner, a plurality of fins, the tubular elements and the fins being superposed one upon another in an alternate manner to form a laminate structure and a pair of end plates attached to outermost ones of the tubular elements at opposite ends of the laminate structure. The end plates each have a joining section joined to an associated one of the outermost tubular elements, and a swelled main portion. The joining section of each end plate includes a joining portion abutting against a portion of one side surface of an associated outermost stamped plate, which portion corresponds in location to a portion of a recess formed in the other side surface of the associated outermost stamped plate. The joining portion is shaped and sized such that at least one row of depressions formed in the one side surface of the associated outermost stamped plate communicates with one of the interior of the swelled main portion of the end plate and the outside of the heat exchanger.
    • 层压型热交换器包括多个管状元件,每个管状元件由一对以邻接方式连接在一起的大致平坦的冲压板形成,多个翅片,管状元件和翅片以交替的方式彼此叠置形成 层压结构和一对端板,其连接到层压结构的相对端处的最外面的管状元件。 端板各自具有连接到相关联的最外面的管状元件之一的接合部分和膨胀的主要部分。 每个端板的接合部分包括接合部分,该接合部分邻接相邻的最外面冲压板的一个侧表面的一部分,该部分位于与形成在相邻的最外面冲压板的另一个侧表面中的凹部的一部分相对应。 接合部的形状和尺寸使得形成在相邻的最外冲压板的一个侧表面中的至少一排凹陷与端板的膨胀的主要部分的内部和热交换器的外部之一连通。

    • An air conditioning system for automotive vehicles wherein the temperature and pressure of refrigerant at the outlet of the evaporator are detected, respectively, by a temperature sensor and a pressure sensor, and the flow rate of refrigerant within the refrigerating cycle is controlled to proper values corresponding to thermal load on the system, by controlling the opening of an expansion valve with a valve control means responsive to output signals from the above sensors. The pressure of refrigerant detected by the pressure sensor is converted by conversion means into a corresponding saturation temperature of the refrigerant. Determining means determines whether or not the refrigerant quantity is insufficient by comparing the difference between the refrigerant temperature and the corresponding saturation temperature of the refrigerant with a predetermined reference value. Indicator means indicates abnormality when the refrigerant quantity is determined to be insufficient. The valve control means causes disengagement of the electromagnetic clutch of the compressor to render the refrigerant compressor inoperative when the refrigerant quantity is determined to be insufficient.
    • 一种用于机动车辆的空调系统,其中分别通过温度传感器和压力传感器检测蒸发器出口处的制冷剂的温度和压力,并将制冷循环内的制冷剂的流量控制到适当的值 通过利用响应于来自上述传感器的输出信号的阀控制装置来控制膨胀阀的打开来进行系统上的热负荷。 由压力传感器检测的制冷剂的压力由转换装置转换成制冷剂的相应的饱和温度。 确定装置通过将制冷剂温度和制冷剂的相应饱和温度之差与预定参考值进行比较来确定制冷剂量是否不足。 当制冷剂量被确定为不足时,指示装置表示异常。 当确定制冷剂量不足时,阀控制装置使压缩机的电磁离合器分离,使制冷剂压缩机不起作用。
