摘要:
A heat exchanger 1 comprises a casing designed as a hollow box by a top plate 11, a bottom plate 12, a front plate 13, a rear plate 14, and two lateral plates 15, 16, and a heat transfer unit 3 accommodated in the casing, and in the heat exchanger, the heat transfer unit has flat plates 4 alternately folded back in reverse direction, and a first flow passage and a second flow passage are alternately formed in multiple layers between the flat plates, and among the front plate and the rear plate running in parallel to a folding line of the flat plate of the casing, a high temperature fluid inlet 21 and a high temperature fluid outlet 22 to be communicated with the second flow passage are provided on the front plate side, and a low temperature fluid inlet 23 and a low temperature fluid outlet 24 to be communicated with the first flow passage are provided on the rear plate side, a lateral plate sealing member 26 to cover the entire region of the end portion and a holding plate 27 with rigidity are interposed between the lateral plate confronted with the end portion of the heat transfer unit and the heat transfer unit, a biasing means 28 is provided between the holding plate and the lateral plate, the biasing means applies pressure on the lateral plate sealing member to the end portion of the heat transfer unit via the holding plate, and the lateral plate sealing member air-tightly closes the end portions of the first flow passage and the second flow passage.
摘要:
A counter-current heat exchanger (1) for use in transferring heat from a hot water output to a cold water input in a plumbing system. The heat exchanger (1) has upper (2) and lower (3) plates with a heat exchange layer (4) therebetween. The heat exchange layer (4) has upper (4a) and lower (4b) sides. A first conduit (7) for the hot water output is formed between the upper side (4a) of the heat exchange layer 4 and the upper plate (2) and a second conduit (8) for the cold water input is formed between the lower side (4b) of the heat exchange layer and the lower plate (3). The first (7) and second (8) conduits are formed as spirals with the heat exchange layer (4) forming a boundary therebetween with the first conduit (7) positioned above the second conduit (8) and the heat exchange layer connected to the lower plate (3) via a sealed connection.

摘要:
A multiple opening, counter-flow plate type exchanger is manufactured by repeatedly folding and joining one strip of membrane (110a, 210a) to form a core (100, 200) composed of a multitude of membrane layers (272, 273) with a plurality of inlet and outlet openings or fluid passageways configured in an alternating counter-flow arrangement. Methods for manufacturing such multiple opening cores are described. An integrated, modular, and stackable plastic manifold that is formed by ultrasonically welding plastic sheet stock is described. Multiple opening cores comprising water-permeable membranes can be used in a variety of applications, including heat and water vapor exchangers. In particular, they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams directed into and out of buildings, automobiles, or other industrial processes.
摘要:
An apparatus for drying a gas to be processed comprises a box-like body, inside which there are received a condensate separator and a first and a second heat exchanger which extend over substantially equal longitudinal portions and which are arranged perpendicularly relative to each other. The first exchanger has heat exchange plates having a thickness different from the thickness of the plates of the second exchanger.
摘要:
With a method of manufacturing a total heat exchange element according to the present invention, in manufacturing a total heat exchange element in which space holding members are provided on both sides of a sheet-like partitioning member, respectively, to form paths and that performs heat exchange via the partitioning member between an air flow flowing through the path formed on one side of the partitioning member and an air flow flowing through the path formed on the other side, the partitioning member and the space holding members are bonded by a water-solvent adhesive in which a water-soluble moisture-absorbing agent is dissolved to make it possible to obtain a total heat exchange element containing a desired amount of moisture-absorbing agent even if a moisture-absorbing agent is not impregnated in or deposited on the partitioning member and the space holding members in advance. Consequently, the partitioning member and the space holding members are prevented from being broken or deformed in a manufacturing process and productivity is improved.
