Patent ID: 7905427

Claim:
A windshield heated liquid spray assembly comprising: a liquid heating assembly; and a heated liquid spray assembly operative to spray heated liquid onto a windshield, said liquid heating assembly comprising: a liquid heating chamber comprising a substantially cylindrical outer sleeve disposed about a longitudinal axis; at least one heating element disposed in said liquid heating chamber; and at least one heat dissipator disposed in said liquid heating chamber in heat conduction contact with said at least one heating element, said at least one heat dissipator having at least one wall at least partially defining at least one substantially linear liquid flow channel parallel to said longitudinal axis and having first and second open ends, said at least one heat dissipator being operative to transfer heat from said at least one heating element to liquid flowing through said at least one liquid flow channel, whereby liquid flows within the at least one liquid flow channel primarily in one direction with respect to the longitudinal axis, from the liquid heating chamber into the first open end to the second open end and into the liquid heating chamber, through convection as heat is transferred to the liquid by the at least one heat dissipator.
