    • Difficulties in obtaining consistent bonds of high quality between side pieces and tubular headers (10), (12) in heat exchangers are avoided in a side piece (42) that extends between the headers (10), (12) and which has circular recesses (48) at each end (44), (46). The recesses (48) define resilient fingers (56), (58) which may separate to receive the ends of the headers (10), (12) and frictionally grasp the same, eliminating the need for fixturing at this location and assuring a strong consistent gripping of the headers (10), (12), by the end piece (42) to assure consistent bonds of high quality.
    • 在集管(10),(12)之间延伸的侧部件(42)中避免了在热交换器中在侧部件和管状集管(10),(12)之间获得高质量的一致的粘合的困难,并且具有圆形凹槽 (44),(46)。 凹口(48)限定弹性指状物(56)(58),其可以分开以接收集流管(10),(12)的端部并且摩擦地抓住它们,从而消除了在该位置固定的需要并确保强 通过末端件(42)对集管(10),(12)进行一致的夹紧,以确保高质量的一致粘合。

    • A header plate (20) is provided for receiving the flattened tubes (14) of a heat exchanger. The header plate (20) includes a plurality of tube receiving openings (26), with each of the openings being surrounded by a flange or collar (28) that extends from a base wall (24) of the header plate (20) towards the heat exchanger core (12) to surround the exterior cross section of the associated tube (14). Each of the flanges (28) is shaped to conform to the exterior of the associated tube (14), and a blend radius R is provided at the interface between the base wall (24) and the flange (28). The blend radius R has a size that increases from a radius R1 central to the length of a long side wall (30) of the flange (28) to a radius R2 central to the length of a short side wall (32) of the flange (28).
    • 集管板(20)设置成用于接收热交换器的扁平管(14)。 集管板(20)包括多个管接收开口(26),其中每个开口由一个凸缘或套环(28)包围,凸缘或套环从集管板(20)的底壁(24)延伸到 热交换器芯(12)以围绕相关管(14)的外部横截面。 每个凸缘(28)成形为符合相关管(14)的外部,并且在底壁(24)和凸缘(28)之间的界面处提供混合半径R. 混合半径R具有从凸缘(28)的长侧壁(30)的中心长度的半径R 1到短边侧壁(32)的长度中心的半径R 2的尺寸, 凸缘(28)。

    • Wireless communication systems (100, 800) comprise mobile units (118, 802) provided with a directional coupler (206) and circuit (220) for measuring the complex reflectance (phase and magnitude) of antenna (202) of the mobile units (118, 802). The system (100, 800) has, either in the mobile unit (118, 802) or elsewhere, a processor (238, 808) programmed to perform pattern recognition of the near field environments of the mobile units (118, 802) by using the complex reflectance measurements as feature vectors. Information as to the near field environment at the time of wireless connection drops is suitably accumulated and is used in network upgrade planning and/or mobile unit design evaluation. The complex reflectance is alternatively used to discriminate antenna faults. Alternatively, near field environments that tend to degrade wireless communication performance are detected by the mobile unit using the complex reflectance and the mobile unit then alerts the user.
    • 无线通信系统(100,800)包括设置有定向耦合器(206)的移动单元(118,802)和用于测量移动单元(118)的天线(202)的复反射率(相位和幅度)的电路(220) ,802)。 在移动单元(118,802)或其它地方,系统(100,800)具有被编程为通过使用移动单元(118,802)执行对移动单元(118,802)的近场环境的模式识别的处理器(238,808a) 复反射测量作为特征向量。 关于无线连接丢失时的近场环境的信息被适当地累积并且用于网络升级规划和/或移动单元设计评估。 复杂的反射率可以用来区分天线故障。 或者,趋向于降低无线通信性能的近场环境由移动单元使用复数反射率检测,并且移动单元然后警告用户。
