Abstract: A process for heating the tubular joints of a heat exchanger assembly to facilitate the creation of a fluid-tight bond between the tubular elements. The joints are positioned adjacent to one or both of the heat exchanger tube sheets and a jet of flammable gas directed into the joint region generally perpendicular to the plane of the tube sheet. The velocity of the gas stream directed at the sheet is high enough to prevent the gas from mixing with ambient air and thus being ignited. Upon impacting the tube sheet, the gas stream is redirected along the sheet, reducing its speed and mixing the gas with surrounding air. A combustible blanket is thus established about the tube joints which is ignited to produce controlled heating thereof.
Abstract translation: 一种用于加热热交换器组件的管状接头以便于在管状元件之间形成流体密封结合的方法。 这些接头位于与一个或两个热交换器管板相邻的位置上，并且将可燃气体射流引导到大致垂直于管板平面的接头区域中。 指向片材的气流的速度足够高以防止气体与环境空气混合，从而被点燃。 在冲击管板时，气流沿片材重新定向，降低其速度并将气体与周围空气混合。 因此可以围绕被点燃的管接头建立可燃毯，以产生受控的加热。

Abstract: This invention relates to apparatus for facilitating the construction of a heat exchanger, such as a condenser or evaporator employed in an air conditioning system, wherein exchanger tubes extending through a plate fin assembly are joined together by means of return bend connections or the like. The ends of the tube are provided with an oval shaped bell in which are telescoped the return bends. Diametrically opposed nibs are formed on the outer surface of the return bend connectors near the distal end thereof. The outside diameter over the nibs is slightly larger than the minor inside diameter of the oval bell. The nibs are inserted into the bell aligned along the minor diameter of the opening. The nibs are thus caused to ride in engagement against the wall of the bell to frictionally support the connector in assembly. The joint is then immersed in a molten solder bath whereby solder flows freely into the joint region along the major axis to create a highly reliable joint.

Abstract: An ultrasonic dip soldering process for bonding the tubular joints of a heat exchanger made up of tubular components joined together to form flow circuits within a fan coil. The joints are positioned adjacent to one of the tube sheets of the fan coil structure and the joints preheated by means of a remote heating process. The joints are then immersed in a molten bath of solder and treated to ultrasonic energy while in the bath.

Abstract translation: 本发明涉及一种用于促进热交换器（例如在空调系统中使用的冷凝器或蒸发器）的构造的装置，其中延伸穿过板翅片组件的交换器管通过回弯连接件等连接在一起。 管的端部设置有椭圆形的钟形，其中可伸缩的弯曲部分。 在靠近其远端的返回弯曲连接器的外表面上形成有直径相对的笔尖。 尖头上的外径略大于椭圆形钟的小内径。 将笔尖插入沿着开口的小直径对准的铃。 因此，笔尖被引入与钟形的壁接合，以摩擦地支撑连接器的组装。 然后将接头浸入熔融焊料浴中，由此焊料沿着长轴自由流入接头区域以产生高度可靠的接头。
