摘要:
A heat exchanger comprises a casing designed as a hollow box by a top plate, a bottom plate, a front plate, a rear plate, and two lateral plates and a heat transfer unit accommodated in the casing. The heat transfer unit has flat plates alternately folded back in reverse direction. A first flow passage and a second flow passage are alternately formed in multiple layers between the flat plates. A high temperature fluid inlet and a high temperature fluid outlet in communication with the second flow passage are provided on the front plate side. A low temperature fluid inlet and a low temperature fluid outlet in communication with the first flow passage are provided on the rear plate side. Biasing means applies pressure on the lateral plate sealing member to the end portion of the heat transfer unit and seals the end portions of the first and second flow passages.

A method of manufacturing a heat transfer system is provided that includes, in one form, preparing a heat conducting array by perforating at least a portion of the heat conducting array, placing the heat conducting array around foam elements, placing a heat conducting spreader along one surface area of the foam elements, placing a lower skin over the heat conducting spreader, placing an upper skin over an opposite surface area of the foam elements to create a structural assembly, and curing the structural assembly. A material of the foam elements flows through the perforated portion of the heat conducting array during the curing step.

A heat and humidity exchanger has example application in exchanging heat and water vapour between fresh air entering a building and air being vented from the building. The heat and humidity exchanger has a self-supporting core formed from layered sheets (710, 720) of a moisture-permeable material. Plenums (750) are arranged to direct fluid streams into and out of the core. The plenums (750) may be on opposing sides of the core to permit counterflow exchange of heat and water vapour. The plenums (750) are attached to the core along opposite edges of the sheets (710, 720).

A vapor condenser is provided which includes a three-dimensional folded structure which defines, at least in part, a set of coolant-carrying channels and a set of vapor condensing channels, with the coolant-carrying channels being interleaved with and extending parallel to the vapor condensing channels. The folded structure includes a thermally conductive sheet with multiple folds in the sheet. One side of the sheet is a vapor condensing surface, and the opposite side of the sheet is a coolant-cooled surface, with at least a portion of the coolant-cooled surface defining the coolant-carrying channels, and being in contact with coolant within the coolant-carrying channels. The vapor condenser further includes, in one embodiment, a top plate, and first and second end manifolds which are coupled to opposite ends of the folded structure and in fluid communication with the coolant-carrying channels to facilitate flow of coolant through the coolant-carrying channels.
