ABSTRACT:
The object of the invention is a method of arranging the cooling in a compactor equipped with at least one roller drum, in which the motor and/or other equipment, for example the hydraulic system, has forced circulation water cooling or water cooled closed forced circulation air cooling. The intention of the invention is to remove the problem of the dirtying of the radiator cells that exists in present cooling systems.
In the method in accordance with the invention the cooling water is circulated through the roller and is brought in thermal contact with the outer covering of the roller in order to transfer the heat from this to the surrounding air and to the ground. Further, a heat exchanger through which coolant flows may also be placed inside the roller, immersed in a second volume of cooling fluid. The heat exchanger may be placed into direct physical contact with the outer cover of the roller.
