Technical Field

[0001] The utility model relates to the field of LNG equipment, in particular to an air cooling system for vehicle-mounted LNG equipment. Background Art

[0002] LNG, also known as liquefied petroleum gas, is a clean energy source. Liquefied petroleum gas is made by subjecting the raw oil and gas mixture to a series of separation, purification and other process steps to remove impurities and unsaturated hydrocarbons, and then compressing and cooling it to gradually liquefy it into liquid liquefied petroleum gas. In the cooling process, air cooling equipment is required. The air cooling equipment includes cooling pipes and cooling fans. In order to increase the heat dissipation area, fins are generally provided on the cooling pipes. However, since vehicle-mounted LNG equipment is often stationed in the wild, the working environment is dusty and dust will accumulate on the cooling pipes, affecting the heat exchange of the cooling pipes. Therefore, it is particularly necessary to develop a vehicle-mounted LNG equipment air cooling system that can clean the dust accumulated on the cooling pipes and keep the cooling pipes with good heat exchange.
