摘要： The present invention is directed to liquid-cooled or air-cooled metallic heat sinks formed as unibody structures that include a planar base and upright fins. The fins are located on one side of the heat sink and the ratio of fin spacing to fin height is low. In order to achieve low value of the ratio of fin spacing to fin height, a fin density of greater than about twelve fins per centimeter is employed. The length of the fins in the flow direction is restricted in order to yield high rate of heat dissipation from the finned surface. Furthermore, flow of the cooling fluid over the fins is maintained laminar in order to reduce the noise level and pumping power for the fluid.

摘要： Heat sinks are provided that achieve very high convective heat transfer surface per unit volume. These heat sinks comprise a spreader plate having a recessed area on one surface and a flat area on another surface, at least two fins and porous reticulated foam blocks having intervening gaps that fill the width and at least a portion of the length between the fins. The foam block may be a continuous single block within the space between two adjacent fins along the length of the fins or may be an array of short-length blocks having intervening gaps along the length of the fins.

摘要： An evaporator used in a vehicle air conditioner has vertical plates with a hybrid corrugated fin between the plates. The leading section of the fin as horizontally oriented corrugations, as is normal, while the trailing section has vertically oriented corrugations. Air passes through louvers in the vertical corrugations, and their vertical orientation aids in water drainage.

摘要： A refrigeration assembly includes a pair of refrigerated chambers defined within a working chamber. The refrigerated chambers include channel walls extending parallel to one another and spaced apart, and first and second panels extending channel walls to define a working channel for separating the working chamber into sub-chambers. Apertures defined in the panels allow airflow from the sub-chambers into the working channel, and a supply of water wets the panels and a first section of the refrigerated chambers. Air enters the sub-chambers and flows over the first sections of the refrigerated chambers for direct evaporative cooling. A portion of the air bleeds through the apertures and evaporates water from the panels prior to flowing over the second sections of the refrigerated chambers for indirect evaporative cooling.

摘要： Two embodiments of a heat exchanger assembly for cooling an electronic device are shown respectively in FIGS. 1 and 3 and each comprises a housing, a plurality of high fins, a plurality of low fins, a nozzle plate, an inlet, at least one outlet, a primary nozzle, and a plurality of secondary nozzles. In the first embodiment shown in FIG. 1, the housing and the nozzle plate are circular in shape. In the second embodiment shown in FIG. 3, the housing and the nozzle plate are rectangular in shape. Both embodiments include a plurality of secondary nozzles that are aligned outwardly of the primary nozzle and the center axis of the nozzle plate. The secondary nozzles direct the flow of the cooling liquid outwardly of the primary nozzle from the center thus creating an overall system pressure drop lower than that of other assemblies without a plurality of secondary nozzles.

摘要： An evaporative heat exchanger for cooling a hot refrigerant having a core of alternatively stacked dry and wet plates. Each dry plate includes a dry side defining a plurality of dry channels in a first direction, a series of ports distributed along the dry channels, a wet side, and a refrigerant cooling section. Each wet plate includes a wet side adjacent to and cooperates with the wet side of the dry plate to define a plurality of wet channels in a second direction. The dry channels, ports, and wet channels define a labyrinth for the air flow, which evaporates the liquid contained in the wet channels resulting in a cooling of the refrigerant. The refrigerant cooling section is integral with the outboard of the dry plate and adjacent to an end section of the wet channels to provide enhanced refrigerant cooling.
