The frame portions of the first and second spacing members further have first and second notches provided in portions of the first and second partition walls, and open on an outer side surface of the first and second partition walls. The seals cover surfaces of the first and second notches.

A heat dissipation device includes a base plate and a plurality of fins arranged on the base plate. Each fin includes a fin body including a first metal sheet and a second metal sheet coupled to each other, wherein the fin body is curved and includes a first portion and a second portion transverse to the first portion, an evaporation channel defined in the first portion, one or more connecting channels disposed in the first portion and in fluid communication with the evaporation channel, a condensation channel defined in the second portion, and one or more auxiliary channels disposed in the second portion and in fluid communication with the one or more connecting channels and the condensation channel.

A heat exchanger including a corrugated heat transfer sheet having a first surface and a second surface on opposite sides thereof, a first flow channel for a first fluid flow in a first flow direction parallel to a longitudinal direction, and a second flow channel for a second fluid flow in a second flow direction parallel to the longitudinal direction, the second flow direction being opposite to the first flow direction. The heat exchanger includes a channel dividing system which provides the first flow channel and the second flow channel on opposite sides of the corrugated heat transfer sheet such that the first fluid flow is adapted to be in contact with the first surface, and the second fluid flow is adapted to be in contact with the second surface.

A plate heat exchanger gasket includes an elongate body and a first number of elongate projections projecting from an upper side of the body and extending along the gasket's longitudinal extension. Each projection is defined by a top and two opposing flanks extending from the top. Referring to a cross section perpendicular to the gasket longitudinal extension, for each of a second number of unsymmetrical projections of the projections, a first area defined by an outer flank of the flanks, the body upper side and a normal of the body upper side extending through the top of the unsymmetrical projection, is smaller than a second area defined by an inner flank of the flanks, the body upper side and the normal of the body upper side extending through the top of the unsymmetrical projection. This normal is displaced from a center normal of the body upper side.

A direct contact steam injection heater that includes a stem plug that is rotatable over 360°. The stem plug is connected to an actuator that is operable to rotate the stem plug over 360° of rotation during both the heating function of the steam injection heater and during a clean-in-place process. The stem plug includes a regulating head having a pair of sealing inserts formed on each of a pair of sealing faces. The sealing inserts are biased outward into contact with an inner surface that includes the steam injection nozzles. As the regulating head rotates between a closed position and an open position, the nozzles are exposed to allow steam to flow into the product being heated. The regulating head further includes a pair of foils. During the clean-in-place operation, the foils create a turbulent flow of cleaning liquid within the steam chamber.

A plate kind heat exchanger (1) has a plurality of stacked plates (2) forming flow paths for heat exchanging fluids there between, a first inlet channel being fluidly connected to inlets of a first set of flow paths, a second inlet channel being fluidly connected to inlets of a second set of flow paths, a first outlet channel being fluidly connected to outlets of the first set of flow paths, and a second outlet channel being fluidly connected to outlets of the second set of flow paths. The first inlet channel is provided with a stack (15) of rings (5) forming fluid passages towards the inlets of the first set of flow paths. Each ring (5) has a first rigid shell member (6) and a second rigid shell member (7), the first rigid shell member (6) and/or the second rigid shell member (7) defining a groove (9) providing fluid passage from the first inlet channel to one of the flow paths of the first set of flow paths, and a sealing member (8) formed from a compressible material, the sealing member (8) being positioned between the first rigid shell member (6) and the second rigid shell member (7). The stack of rings (15) is subjected to a force which presses the rings (5) towards each other and compresses the sealing members (8) of the rings (5), thereby providing sealing towards the flow paths of the second set of flow paths.

A heat exchanger and method of making same are disclosed. In another aspect, a method of making a heat exchanger includes sintering powder metal and hot isostatic pressing of the powder metal. Moreover, an aspect of the present heat exchanger apparatus employs plates in a stacked arrangement with supercritical-CO.sub.2 flowing between the plates and between adjacent fins. Still another aspect of a heat exchanger apparatus is made of a nickel-based alloy.

A gasket for a plate heat exchanger, wherein the gasket includes a body in the form of a loop for fitting to a plate of the plate heat exchanger. The body includes one or more peripheral connection areas spaced along at least one side of the loop, and a plurality of tabs for securing the gasket in position on the plate. Each tab is discrete from the body, and each tab includes a connection which is receivable by or engageable with one of the connection areas to connect the tabs and body together.

A seal including a first portion having a first width that extends in a radial direction of the seal, a second portion that is joined with the first portion and having a second width that is smaller than the first width, and a first recess that is located in the first portion to reduce a width expansion of the first portion when the seal is compressed in an axial direction of the seal.

Tool-less apparatus and methods are provided for sealing flow of cooling air from the outlet of a cooling fan blower to the inlet of a heat exchanger within a chassis enclosure of an information handling system. The disclosed apparatus and methods may be implemented in a tool-less manner by employing tool-less chassis mounting features that mate with tool-less cooling fan mounting features to mechanically align and secure an air outlet of a cooling fan blower in sealing relationship with an air inlet of a heat exchanger within a chassis enclosure of an information handling system by properly aligning the axes of a cooling fan in relation to the inlet of the heat exchanger so that in on embodiment no gap exists between the cooling air outlet of the cooling fan and the cooing air inlet of the heat exchanger.
