Abstract

DC60 (29/04/47) The heat exchanger is directly connected to the internal combustion engine. The heat exchanger consists of a radiant heat exchanger unit composed of several circular cross-sectional coolant tubes and plate-shaped radiant heat fins attached to and arranged longitudinally on the coolant tubes at various points, and a pair of tanks arranged on opposite sides of the radiant heat exchanger unit, respectively, and connected to opposite ends of several coolant tubes. The heat exchanger is directly connected to the internal combustion engine. The heat exchanger consists of a radiant heat exchanger unit composed of several circular cross-sectional coolant tubes and plate-shaped radiant heat fins attached to and arranged longitudinally on the coolant tubes at various points, and a pair of tanks arranged on opposite sides of the radiant heat exchanger unit, respectively, and connected to opposite ends of several coolant tubes.

Claims (4)
