Abstract: A heat exchanger includes first and second plates joined together with portions of the inner surfaces spaced apart to define a plurality of fluid flow passages for flow of a heat transfer fluid. A dividing rib separates the heat exchanger into an inlet section and an outlet section, each of which includes a plurality of fluid flow passages. Inlet and outlet ports are located near a first end of the heat exchanger, on opposite sides of the dividing rib. The heat transfer surface area of the inlet section is less than that of the outlet section due to the presence of one or more flow obstructions between the inlet port and first ends of the fluid flow passages in the inlet section. Each flow obstruction may be a dead channel including a continuous outer rib completely surrounding a depressed middle region.

Abstract: A heat exchanger has a fluid flow passage having an inlet and an outlet, and with a first plate and a second plate in opposed facing relation to one another.

An electrical heating element is outside the fluid flow passage and adjacent to the outer surface of the first plate, such that heat produced by the electrical heating element is transferred through the first plate to the fluid in the fluid flow passage during use of the heat exchanger. In an embodiment, the first plate has an opening to receive a heater plate component including a first plate portion having an inner surface bonded to a turbulence-enhancing insert and an outer surface bonded to the electrical heating element.
