    • A heat exchanger utilizes a multi-hole flexible band (1) of light metal which is formed, by extrusion, with a plurality of longitudinal small holes (2) extending in parallel to one another from one band end to the other end (3). The longitudinal holes (2) are connected at each of the end portions (3) of the band, and both ends of the band is closed by welding to form a sealed cavity partly filled with a working fluid in partial vacuum. The sealed cavity may be in the form of a single long continuous passage, or in the form of parallel passages connected together at both ends. The multi-hole band is bent in such a shape that the band meanders between a high temperature region and a low temperature region. The thus-constructed heat exchanger is advantageous in heat exchanging performance, and capable of reducing the manufacturing and material costs, the weight of the heat exchanger, and improving the reliability.
    • 热交换器利用轻金属的多孔柔性带(1),该多孔柔性带通过挤压形成有从一个带端到另一端(3)彼此平行延伸的多个纵向小孔(2) 。 纵向孔(2)在带的每个端部(3)处连接,并且带的两端通过焊接闭合以形成部分充满部分真空中的工作流体的密封腔。 密封的空腔可以是单个长连续通道的形式,或者是两端连接在一起的平行通道的形式。 多孔带被弯曲成使得带在高温区域和低温区域之间曲折的形状。 这样构造的热交换器在热交换性能方面是有利的,并且能够降低制造和材料成本,热交换器的重量并且提高可靠性。
