  • Heat exchanger II
    Patent number: 9810485
    Abstract: A heat exchanger comprises a stack of mutually spaced apart plates. The plates are separated by respective spacings therebetween. Alternate spacings respectively provide a flow path for a first fluid and a second fluid. The heat exchanger further comprises a first header for inflow of the first fluid and a second header for outflow of the first fluid. The first and second headers are connected to the plate stack by flexible tubular ducting means.
    Type: Grant

  • Heat exchanger with multi-plate structure and use thereof
    Patent number: 8616269
    Abstract: A heat exchanger comprises a plurality of plates (7, 9, 11, 13) each having first (15, 19) and second (17, 21) heat transfer surfaces on reverse sides. The plates are arranged in a stack with spacings between mutually facing heat transfer surfaces of adjacent plates. Alternate spacings in the stack providing respectively, a first fluid path (51, 52) for a first fluid and a second fluid path (57, 59) for a second fluid. The plates are arranged in a plurality of groups, each comprising at least two plates. Pin means are provided in the form of a plurality of groups of pins (23). The pins of each pin group are arranged to bridge plates of a respective plate group.
