Abstract

The invention discloses a hung type diesel locomotive cooling device which comprises a water cooling system, a hydraulic oil cooling system, a pressurizing air cooling system, a transmission oil cooling system, a steel die frame, a bearing seat, a hydraulic motor, a fan, an air cylinder, an air guide section, a protecting net and a dustproof net, wherein the cooling device is of induced draft design; the four cooling systems are respectively fixedly arranged at the air inlet end of the steel die frame; the air outlet end of the steel die frame is fixedly connected with the air guide section; the air guide section is fixedly connected with the air cylinder; the bearing seat is fixedly arranged in the middle of the air cylinder; the fan and the hydraulic motor are respectively arranged at two ends of the bearing seat; the fan is wrapped by the air cylinder. The four cooling systems, the hydraulic motor, the protecting net, the dustproof net and the like are all fixed on the steel die frame by using bolts, thus being convenient to clean, disassemble and replace. The hung type diesel locomotive cooling device is compact and reasonable in structure, good in cooling property, reasonable in air field flow, high in energy utilization rate, low in noise, simple in manufacturing process, convenient to maintain and replace, and relatively good in security protection property.

Description

technical field [0001] The invention relates to the technical field of cooling equipment, in particular to a hanging cooling device for a diesel locomotive. Background technique [0002] With the rapid development of the 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 diesel locomotive. [0003] When a diesel locomotive is working, it needs to cool many heat-generating components on the vehicle. The existing cooling systems include diesel engine water cooling systems, hydraulic oil cooling systems, pressurized air cooling systems, transmission oil cooling systems, etc., and each cooling system is usually separated. , to be cooled...
