摘要:
A wire spacer (20) for spacing two adjacent heat transfer plates (2, 4) of a plate type heat exchanger (1). The wire spacer (20) is formed by a bent wire (22) that is alternatingly abutting the two adjacent heat transfer plates (2, 4), while extending along the fluid channel (6, 8) of the heat exchanger (1). The wire spacer (20) has first and second support segments (24, 26) providing a plate supporting function, and spacing segments (28) for maintaining a minimal vertical spacing (Δy) between the heat transfer plates (2, 4) during heat exchanger operation. The first lower support segments (24) are formed by wire paths (32) that span a plane (S1) coinciding with a top surface of the lower heat transfer plate (2), and allow the wire spacer (20) to keep its orientation fixed with respect to the heat transfer plates.

Piggable plate heat exchanger assemblies enable piggable cleaning of interior surfaces thereof. Piggable plate heat exchanger assemblies include an inner plate member and first and second channel forming members with adjacently positioned first and second channel forming extension plates to enclose the inner plate member to form first and second channels for first and second fluid flow. Other piggable plate heat exchanger assemblies include plate members and first and second end members in conjunction with corresponding plate members positioned at first and second ends of corresponding plate members to form first and bypass channels to flow first and second fluids. Still other piggable plate heat exchangers include a plurality of plate members and a plurality of end members forming in conjunction with the plate members a first channel and a second channel in an interweaving relation for flow of a first fluid substantially normal to flow of a second fluid.

A dehumidifier includes a suction unit, a dehumidifying unit having a chiller, a discharge unit having a heat radiator, a refrigerant circulating system, and a heat exchanger. The suction unit sucks humid air into the dehumidifying unit, which cools the humid air and condenses the moisture in the humid air to create dry air. The discharge unit heats and discharges the dry air coming from the dehumidifying unit, and the heat exchanger exchanges heat between the humid air and the dry air coming from the dehumidifying unit. The refrigerant circulating system is used to cool the humid air at the dehumidifying unit and to heat the dry air at the discharge unit. In some embodiments, the heat exchanger includes a heat transfer unit, wherein flat plates are turned back alternately in opposite directions, and a first and second flow passage are prepared alternately in many layers between the flat plates.
摘要:
A heat and humidity exchanger has example application in exchanging heat and water vapor 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 of a moisture-permeable material. Plenums are arranged to direct fluid streams into and out of the core. The plenums may be on opposing sides of the core to permit counterflow exchange of heat and water vapor.

摘要:
A multiple opening, counter-flow plate type exchanger is manufactured by repeatedly folding and joining one strip of membrane to form a core composed of a multitude of membrane layers 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.

A modular system for heat exchange between fluids includes a plurality of open elements that, by means of two end plates, are connected together. An open element is constituted of a folded and sealed sheet material that is arranged in a frame.
摘要:
A total heat exchanger of the present invention facilitates circulation of two types of air currents separated by a partition plate and conducts heat exchange of sensible heat and latent heat of the two types of air currents across the partition plate, wherein the partition plate has a porous resin base material layer, a fissured layer having a thickness of 2 μm or more and 50 μm or less and composed of a hydrophilic moisture-permeable resin, and a nonporous hydrophilic moisture-permeable resin film layer having a thickness of 0.5 μm or more and 10 μm or less laminated in this order. The total heat exchanger of the present invention can prevent reduction in performance even in an environment of repeated condensation and has a high total heat exchange efficiency.
