PROBLEM TO BE SOLVED: To make a radiator for lowering the temperature of a liquid coolant unnecessary, and to heighten a maintenance-free effect, by connecting a liquid- cooled motor and a pump into a closed loop by the use of a pipe wound spirally around the side beams of a truck, and circulating the liquid coolant in a passage connected to this closed loop. SOLUTION: Pipes 8 are wound spirally along the side beams 6 of a truck 6. A liquid-cooled motor 1 is connected through pipes 8, 8' to a pump 7 for circulating a liquid coolant, and a closed-loop circulating passage is formed. The liquid coolant flows in the closed-loop circulating passage in the order of the liquid-cooled motor 1, the pipes 8', the pump 7, the pipes 8, and the liquid-cooled motor 1. The liquid coolant whose temperature has increased as the result of cooling the motor receives a running wind of the car directly, and is cooled by the use of the long pipes 8 wound along the side beams 6 of the truck. Along with it, heat is transmitted by heat conduction also to the truck components, being cooled by the running wind and having larger thermal capacities, of the truck and cooled. |
