Description

Technical Field

[0001] The utility model relates to a thermal insulation curtain and belongs to the technical field of engineering machinery radiators. Background Art

[0002] At present, mining hydraulic excavators and other engineering machinery vehicles are all equipped with radiators for heat dissipation of engine cooling water and hydraulic oil. When used in extremely cold areas such as high latitudes, or in cold weather, even if the radiator fan runs at a very low speed, the ambient temperature can easily take away the temperature at the initial start of the vehicle, resulting in difficulty in starting the vehicle and warming up the vehicle. After starting, the working state of the vehicle dissipates heat quickly, causing the engine to work at a low temperature, which not only causes poor lubrication, but also leads to low combustion efficiency and high fuel consumption. A device is needed to keep the radiator warm in a cold environment, and is simple to disassemble or easy to use. Summary of the invention

[0003] The utility model provides a thermal insulation curtain. When working in a low temperature environment in an extremely cold area, the curtain is lowered and fixed to limit the air intake of the radiator and keep the vehicle warm.
