  • Patent number: 10260826
    Abstract: An apparatus and a method for cleaning heat transfer plates suspended between end plates of an open plate heat exchanger are provided. The apparatus includes a spraying device including a first rod, at least a first nozzle arranged on a nozzle side of the first rod, which nozzle side is arranged to face a first heat transfer plate side, a second rod and at least a second nozzle arranged on a nozzle side of the second rod, which nozzle side is arranged to face a second heat transfer plate side. The first and second rods are essentially parallel and connected. The spraying device has a first mode in which the first and second rods are arranged to move between the heat transfer plates in a first direction perpendicular to a longitudinal extension of the first and second rods and parallel to an extension plane of the heat transfer plates. Meanwhile, the first and second nozzles are arranged to spray cleaning fluid onto the first and second heat transfer plate sides, respectively.

  • Patent number: 9846001
    Abstract: A heat exchanger assembly comprises a heat exchanger for heat exchange between at least a first heat exchange fluid and a second heat exchange fluid. The heat exchanger comprises at least one heat transfer element delimiting a first fluid path from a second fluid path, and a through connection for the first heat exchange fluid arranged at a first side portion of an outer structure of the heat exchanger. The assembly comprises a pressure pulse damping apparatus comprising an elastic element, and a first conduit leading to the elastic element. The first conduit comprises a first opening connected to the through connection of the heat exchanger such that the first conduit is fluidly connected with the first fluid path. The elastic element fluidly communicates with the first fluid path only via the first opening. There is further disclosed use of a pressure pulse damping apparatus comprising an elastic element.
