    Abstract: A method for forming a joint between a tube and a sheet includes forming an anvil at least within the tube, and welding the tube to the sheet in the presence of the anvil. The anvil includes an anchor which is placed within the tube near or at the joint to be formed. At least one washer is placed over the end of the anchor that is near the joint to be formed. A threaded fastener is then placed into the anchor to securely hold the anchor within the tube and to provide a backing substantial enough so that a friction stir weld can be formed. The threaded fastener and the washer can be used as a guide for the friction stir weld. Once the weld is completed, the anvil can be removed. The weld can be further processed to remove burrs and other material.

    Abstract: A hybrid plate-fin heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed. The hybrid plate-fin heat exchanger comprises a plurality of plates, each of which comprises channels for conveying the first fluid. Fins are brazed onto each plate, wherein the fins define a plurality of flow channels for the second fluid. The plates are joined to one another via friction-stir welding in such a way that the brazed regions are fluidically isolated from the first fluid during operation. As a result, the heat exchanger is suitable for use in applications that use a first fluid, such as seawater or geothermal fluid, which is corrosive for the brazed regions.

    Abstract: A heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed; wherein the heat exchanger has improved thermal efficiency and low fluid back pressure. The heat exchanger comprises conduits for conveying the first fluid, wherein the conduits include a plurality of flow passages. The flow passages are defined by a plurality of fins that are continuous along the direction of flow of the first fluid. Each fin includes a wave-shaped region, and adjacent fins sub-divide each flow passage into first and second sections that are interposed by a third section. The wave-shape of the fins creates a continuously varying cross-sectional area for each third section. The variation of the cross-sectional area of the third section, coupled with the wave-shape of the fins, induces a swirl flow between the third section and each of the first and second sections. This swirl flow improves the efficiency of the overall convection heat transfer in each conduit. Further, the overall cross-sectional area of each conduit remains constant even as the cross-sectional areas of individual flow passages changes, which mitigates the development of back pressure in the flow of the first fluid.

    Abstract translation: 公开了一种用于在第一流体和第二流体之间进行热交换的热交换器; 其中所述热交换器具有改善的热效率和低流体背压。 热交换器包括用于输送第一流体的导管，其中导管包括多个流动通道。 流动通道由沿着第一流体的流动方向连续的多个翅片限定。 每个翅片包括波形区域，并且相邻的翅片将每个流动通道分成由第三部分插入的第一和第二部分。 翅片的波形对于每个第三部分产生连续变化的横截面积。 第三部分的横截面积的变化与散热片的波浪形状引起第三部分与第一和第二部分中的每一个之间的旋流。 这种涡流提高了每个导管中整体对流传热的效率。 此外，即使各个流道的横截面积改变，每个管道的总横截面面积也保持恒定，这减轻了第一流体流动中背压的发展。

    Abstract: A heat exchanger comprising a plurality of plates that are demountably attached to a frame is disclosed. Each plate comprises a plurality of channels for conveying a primary fluid through the heat exchanger. The frames are arranged in the frame so that spaces between adjacent frame pairs define conduits for conveying a secondary fluid through the heat exchanger. The plates are mounted in the frame so that they can be individually removed from the frame. Further, each of the channels is fluidically connected to input and output ports for the primary fluid by detachable couplings. As a result, heat exchangers in accordance with the present invention are more easily repaired or refurbished than prior-art heat exchangers.

The described heat exchangers can be used in a variety of applications, including but not limited to, low thermal driving force applications, power generation applications, and non-power generation applications such as refrigeration and cryogenics. The foam heat transfer units can be made from any thermally conductive foam material including, but not limited to, graphite foam or metal foam. In an embodiment, the heat exchanger utilizes tubes that are twisted around a central foam heat transfer unit.
