Abstract

The invention discloses a cooling device of an electric drive bulldozer. The cooling device comprises an engine cooling device which is used for cooling mechanical heat source parts; the cooling device also comprises a circuit cooling device which is used for cooling electronic heat source parts. The circuit cooling device is added on the cooling device of the electric drive bulldozer on the basis of the existing engine cooling device, so that the electronic heat source parts of the electric drive bulldozer can be independently cooled, therefore, the cooling device is not only beneficial to intensifying the heat dissipation capability of the electronic heat source parts with a relative lower working temperature, and simultaneously, is beneficial to ensuring the heat dissipation reliability of the high temperature mechanical heat source parts, such as engine, and further, the cooling effect of the cooling device of the electric drive bulldozer is improved. In addition, the invention also discloses an electric drive bulldozer which comprises the cooling device.

Description

technical field [0001] The invention relates to the technical field of cooling systems, in particular to a cooling device for an electrically driven bulldozer. In addition, the present invention also relates to an electrically driven bulldozer comprising the above-mentioned cooling device. Background technique [0002] Electric drive bulldozers use generators and drive motors to replace gearboxes and torque converters in traditional hydraulic mechanical bulldozers in the bulldozer transmission system, which is obviously different from the transmission structure of traditional bulldozers, and accordingly, the cooling objects are also significantly different. [0003] The cooling objects of traditional mechanical transmission bulldozers are mainly mechanical heat source components such as the engine, gearbox, side reducer and intercooler. The temperature of the coolant is generally above 100°C. , The hydraulic system uses air cooling. In addition to the mechanical heat sourc...
