A windshield washer fluid heater having a housing which defines a housing chamber. A subhousing is disposed in the housing chamber. This subhousing is constructed of a thermally conductive material and divides the housing chamber into an outer housing chamber between the housing and the subhousing, and an inner housing chamber inside the subchamber. The outer housing chamber and inner housing chambers are fluidly isolated from each other. A core is disposed in the inner housing chamber thus forming an annular fluid chamber between the core and the subhousing. A washer fluid inlet on the housing is open to one end of the annular chamber while a washer fluid outlet at the other end is open to the other end of the annular chamber. An engine coolant inlet is open to the outer chamber while an engine coolant outlet is also open to the outer chamber at a position spaced from the inlet so that fluid flow into the coolant inlet flows through the outer housing chamber and to the coolant outlet. Alternatively, an electric heater is used to heat the housing chamber containing the annular fluid chamber.

A windshield washer fluid heater for an automotive vehicle has an elongated housing with two open ends and in which the housing defines a housing chamber. A tubular subhousing divides the housing chamber into an outer housing chamber and an inner housing chamber. A core is disposed in the inner housing chamber and this core forms an annular chamber between the core and the subhousing. A pair of end caps is attached to the ends of the housing and these end caps sealingly engage the housing and the subchamber to fluidly separate the outer housing chamber from the annular chamber. The housing includes a washer fluid passageway which fluidly connects a washer fluid port on the end cap with the annular chamber as well as a coolant fluid passageway which fluidly connects a coolant port on each end cap with the housing chamber.

The invention relates to an electrical and hydraulic coupling device 10 for a system for supplying and / or distributing liquid to be sprayed onto a window of a vehicle, comprising at least one tube 22 and at least one first electrically conductive cable 21, 34, the tube 22 is delimited by a wall 25 in which are formed at least two liquid circulation ducts 23, 24 and in which is embedded a heating element 26, said wall comprising at least one recess 37 open towards the outside of the tube 22 and in which is housed all or part of said cable 21, 34. The invention also relates to the applications in motor vehicles.

A windshield washer fluid reservoir tank for a vehicle is externally formed with a side stepping surface, and is internally defined with a space for storing windshield washer fluid replenished through a feeding pipe having a cap, and for allowing the windshield washer fluid stored therein to be pumped to a windshield of the vehicle through supply hoses under the operation of a supply motor pump installed in position within the windshield washer fluid reservoir tank, in order to ensure extended use of the windshield washer fluid without requiring frequent replenishment, by virtue of such a space having a sufficient storage capacity capable of storing a large amount of the windshield washer fluid.

A pipe structure of a windshield washer fluid feeding device for a vehicle includes a refill pipe which is used for the feeding of windshield washer fluid into a windshield washer fluid reservoir tank and has a multiply-curved form ensuring a sufficient working space between the refill pipe and a head lamp unit of the vehicle, and an auxiliary pipe connected at both ends thereof to certain portions of the refill pipe. With the combined configuration of the refill pipe and auxiliary pipe, even if the windshield washer fluid freezes, a joint region between the windshield washer fluid reservoir tank and the refill pipe is protected from damage.
