    摘要: An apparatus includes a chimney cooler having a housing. The housing includes a base and sidewalls. The base is configured to support one or more heat-generating components. The sidewalls extend from the base, and each sidewall includes multiple channels. Each channel defines a serpentine flow path configured to receive a fluid coolant. The sidewalls may be lofted away from the heat-generating component(s) as the sidewalls extend from the base. An inlet for each channel may be contoured to promote inertial flow of the fluid coolant into the serpentine flow path. An outlet for each channel may be contoured to promote inertial flow of the fluid coolant exiting the serpentine flow path. Channels at and adjacent to primary objective surfaces of the housing may share a common inlet. The channels at the primary objective surfaces of the housing may have larger outlets relative to the channels adjacent to the primary objective surfaces of the housing.

    摘要: The invention provides a cooler apparatus and a method use. The cooler apparatus has at least one heat exchange conduit passing through a cooling medium. The method comprises flowing a fluid to be cooled through the at least one heat exchange conduit from a first cooler inlet to a first cooler outlet, to cool the fluid from an inflow temperature to an exit temperature by heat exchange with the cooling medium. In an aspect of the invention, the flow of the fluid through the at least one heat exchange conduit and the flow of the cooling medium are controlled to cause a local increase in a temperature in a selected portion of the at least one heat exchange conduit. This causes deposits of solids to be released from an inner surface of the selected portion of the at least one heat exchange conduit into the flowing fluid. The method may comprise restricting or containing the cooling medium around the selected portion of the at least one heat exchange conduit, and/or controlling the flow of the fluid to be cooled by re-routing the flow path of the fluid through a selected inlet of the at least one heat exchange conduit.

    摘要: A heat exchanger includes a plurality of heat exchange tube segments defining a plurality of fluid pathways therein and a plurality of fins disposed between adjacent heat exchange tube segments of the plurality of heat exchange tube segments. A bend is formed in the plurality of heat exchange tube segments defining a first portion of the heat exchanger located at a first side of the bend, and a second portion of the heat exchanger located at a second side of the bend opposite the first side. A support is positioned at or near the bend, the support including and includes a support base and at least one support finger extending from the support base and into a gap between adjacent heat exchange tube segments of the plurality of heat exchange tube segments.

    摘要: A heat exchanger having: a first heat exchanger core including a first sub-heat exchanger core and a second sub-heat exchanger core, wherein the first sub-heat exchanger core and the second sub-heat exchanger core includes heat exchange tubes, the heat exchange tubes of the first sub-heat exchanger core and the second sub-heat exchanger core are connected to each other, and orthographic projections of the first sub-heat exchanger core and the second sub-heat exchanger core on a plane where the second sub-heat exchanger core is located at least overlap partially; and a second heat exchanger core including a heat exchange tube, wherein the heat exchange tube of the second heat exchanger core is connected to the heat exchange tubes of the first sub-heat exchanger core and the second sub-heat exchanger core is disclosed. At the same incoming wind speed, the ratio of the wind resistance of the heat exchanger to the air passing through the first heat exchanger core to the wind resistance of the heat exchanger to the air passing through the second heat exchanger core is less than a predetermined value. By using the heat exchanger according to the present invention, the performance of the heat exchanger can be improved.
