Abstract

A heat exchanger for heating washer fluid supplied to motor vehicle windshield washer nozzles simultaneously with diesel oil supplied to the diesel engine of the vehicle is disclosed. Engine coolant heats a tank containing separate coils through which the washer fluid and diesel oil circulates.

Claims

1. Surface type heat exchanger for heating washer fluid feeding the windshield washer system of a diesel engine powered vehicle and for heating diesel oil supplied to the diesel engine comprising:

two copper coils, a larger diameter one connected to a diesel oil supply and wound in several close circular spires enclosed in a tank (1),

said tank (1) consisting of two circular half shells in basin form that are fit together and welded,

input and output nozzles (2a and 2b) for said diesel oil coil issue from the tank (1) and are formed close to each other and parallel, diametrically opposed to input and output nozzles (3a and 3b) of said other coil through which washer fluid is circulated,

said tank having inlet and outlet nozzles (4a and 4b) connected for flow of hot engine coolant and installed at the center of the top and bottom ends of said two half shells.
