Claim 5:
6. The heat exchanger of claim 1, further comprising:
a second electrical heating element provided outside the fluid flow passage and located adjacent to the outer surface of the second plate, such that heat produced by the second electrical heating element is transferred through the second plate to the fluid in the fluid flow passage during use of the heat exchanger;
wherein the second electrical heating element has a thickness from about 1 μm to about 1000 μm;
wherein the second electrical heating element comprises an electrically insulating dielectric base layer which is closest to the outer surface of the second plate, and an electrically resistive heater layer on the dielectric base layer; and
wherein the dielectric base layer comprises a thermally conductive, electrically insulating composite layer comprising a polymer mixed with a particulate filler material.
