A heat exchanger assembly (2) comprising a heat exchanger (4) for heat exchange between at least a first heat exchange fluid and a second heat exchange fluid is disclosed. The heat exchanger (4) comprises at least one heat transfer element delimiting a first fluid path from a second fluid path, and a through connection (20) for the first heat exchange fluid arranged at a first side portion of an outer structure of the heat exchanger (4). The assembly (2) comprises a pressure pulse damping apparatus (6), the apparatus (6) comprising an elastic element, and a first conduit (22) leading to the elastic element. The first conduit (22) comprises a first opening connected to the through connection (20) of the heat exchanger (4) such that the first conduit (22) is in fluid connection with the first fluid path. The elastic element is in fluid communication with the first fluid path only via the first opening. There is further disclosed use of a pressure pulse damping apparatus (6) comprising an elastic element, and a first conduit (22) leading to the elastic element for damping pressure pulses in a heat exchanger (4).
Description
technical field [0001] The present invention relates to a heat exchanger assembly and to the use of a pressure pulse dampening device for damping pressure pulses in a heat exchanger. Background technique [0002] Heat exchangers for exchanging heat between at least a first heat exchange fluid and a second heat exchange fluid are used in many different types of applications and processes, such as, for example, offshore oil platforms, steam condensation systems, and fertilizer plants . Heat exchangers can be used for many different purposes such as, for example, cooling and heating fluids, condensing gases and evaporating liquids. [0003] In some applications, pressure pulses may exist in the heat exchange fluid. For example, if a heat exchange fluid is a liquid in which a slug of gas can exist, a pressure pulse can occur in the application. For example, offshore oil platforms containing oil, water, and fossil gases produce aqueous crude oil from drilling wells. The aqueo...
