Abstract:
A heat exchanging device has a main chamber, two sub-chambers, an inlet and an outlet. The sub-chambers extend outwardly from both planar walls of the main chamber. Disposed within main chamber and the sub-chambers is a medium directing insert. The insert has an angled surface on ends facing the inlet and the outlet, first directing the flow of the heat exchange medium into the main chamber, so that the heat exchange medium is dispersed within the main chamber, then directing the heat exchange medium out of the device through the outlet. The medium directing insert is bonded to the lateral walls of the sub-chambers to enhance the structural integrity of the device. The lateral walls of the medium directing insert cooperate with the planar and lateral walls of the main chamber to form channels for directing flow of the heat exchange medium within the device.
Abstract:
Disclosed is a heat exchanger that has an internal air flow pattern such as a helical pattern. The heat exchanger includes a shell that encompasses an inner series of heat exchange tubes and an outer series of heat exchange tubes. A baffle sheet is juxtaposed next to the outer series of heat exchange tubes. And the baffle sheet is configured to direct air flow within the heat exchanger in a configuration, such as a helical configuration, from a center of the shell toward an outer region of the shell.
Abstract:
Disclosed is a heat exchanger having an economizer configured as a ring of tubes in a periphery of the heat exchanger. The heat exchanger includes a cylindrical flue collector and a manifold at either end of the cylindrical flue collector. The manifold has a plurality of chambers. The manifold can be made of steel or plastic and governs fluid flow rate and direction within a ring of tubes. At least two rings of heat exchanging tubes, an outer ring and an inner ring, are within the cylindrical flue collector. The rings of tubes are concentric with respect to each other.
Abstract:
According to the present disclosure, an evaporating unit (40a) for cooling a heat emitting device (10) is provided. Typically, a cooling circuit (20a) comprises a stack (22) of evaporating units (40a) arranged in alternation with heat emitting devices (10). Each evaporating unit (40a) is connected to a condenser (80) and comprises a first inlet channel (43a), a first plurality of evaporation channels (45a), and a first outlet channel (50a). The evaporating unit (40a) is designed to pre-heat the cooling fluid flowing therein.

Abstract:
The invention relates to a plate heat exchanger (1) and a method for manufacturing a plate heat exchanger. In a plate heat exchanger according to the invention, baffle plates (7, 7') have been arranged between the outer surface of the plate pack ( 6 ) and the outer casing surrounding the plate pack, which baffle plates form a flow channel ( 9 ) between the outer surface of the plate pack and the outer casing for at least one heat-yielding and/or at least one heat - receiving heat exchange medium from the inlet connection (4, 5) to the plate pack and a flow channel ( 9' ) from the plate pack to the outlet connection (4', 5' ).
