HEAT EXCHANGERS WITH INTEGRATED ELECTRICAL HEATING ELEMENTS AND WITH MULTIPLE FLUID FLOW PASSAGES

A heat exchanger has at least one channel structure defining a fluid flow passage. Each channel structure includes first and second thermally conductive plates, with a fluid flow passage defined by a space between the inner surfaces of the first and second plates. At least one electrical heating ele...

Beschreibung
Zusammenfassung:A heat exchanger has at least one channel structure defining a fluid flow passage. Each channel structure includes first and second thermally conductive plates, with a fluid flow passage defined by a space between the inner surfaces of the first and second plates. At least one electrical heating element is provided outside the fluid flow passage and located adjacent to the outer surface of the first plate, such that heat from the heating element is transferred through the first plate to the fluid in the flow passage during use of the heat exchanger. In some embodiments, the first plate of the first channel structure is arranged opposite to the first plate of the second channel structure, with spacers received between the first and second channel structures. At least one of the spacers may have fluid transfer openings to provide flow communication between the first and second channel structures.
