Fluid heating attachment for automobile engine cooling systems
This patent describes a fluid heating attachment for automobile engines cooling systems with a device for warming the engine and prewarming the washer fluid when the engine is not running, and for also warming the washer fluid when the engine is running. The attachment consists of: a housing having a heating chamber and having an inlet and an outlet connected in communication with the chamber, the housing inlet and outlet being connected in communication with the radiator outlet hose and space heater supply hose, respectively, thus to connect the chamber in the cooling system as part of the flow path of coolant circulated through the system and thereby fill the chamber with the circulated coolant; a tubular conduit means for windshield washer fluid, supported within the chamber in position to be substantially wholly immersed in the coolant filling the chamber; the conduit means including inflow and outflow ends projecting exteriorly of the chamber and respectively connected to the inlet and outlet end portions of the windshield washer fluid supply line to provide a heated supply of washer fluid for the spray head; and heating means within the chamber for elevating the temperature of the coolant and the washer fluid therein, the heating means comprising an electrical heating element wholly immersed in the coolant within the chamber in laterally spaced relation to the conduit means and adapted for connection to a supply of house current, from the housing to the space heater supply hose and into the upper end of the block, and thereafter downwardly through the block to the lower end thereof to displace and force upwardly coolant that is of a lower temperature.
