Abstract

The invention discloses a modularized cooling device for an internal combustion locomotive. The modularized cooling device for the internal combustion locomotive comprises a water cooling system, a pressurized air cooling system, a transmission oil cooling system, a static-pressure oil cooling system, a fan set and a steel frame and is characterized in that the steel frame is composed of a fan rack and a cooling device mounting rack fixed at the lower end of the fan rack, a fan drum is arranged inside the fan rack, and the fan set is arranged inside the fan drum; the water cooling system, the pressurized air cooling system, the transmission oil cooling system and the static-pressure oil cooling system are arranged inside the cooling device mounting rack. The modularized cooling device for the internal combustion locomotive is compact in structure and reasonable in matching; has good heat exchange capacities and relatively low air pressure losses and accordingly saves energy sources; simplifies the manufacturing process and reduces the production costs; is dirt-proof and easy to maintain, thereby reducing the use cost; facilitates working environment improvement due to appropriate noise reduction measures.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a modular cooling device for a diesel locomotive. Background technique [0002] With the development of the modern railway industry, diesel locomotives play an irreplaceable role in many aspects of rail transportation. As an important part of the cooling system of a diesel locomotive, the cooling device maintains the normal operation of the core components of the diesel locomotive such as the diesel engine and the hydraulic transmission box, and plays an important role in the safe and stable operation of the locomotive. Usually, when the diesel locomotive is running, the main components (diesel engine, hydraulic transmission box, etc.) on the vehicle are required to be systematically cooled. The main cooling devices usually include fan units, hydraulic motors, water radiators, oil radiators, and air coolers. Decentralized and independent cooling devices will take up a larg...
