[0001] This utility model relates to the field of cooler technology, specifically to an air-water composite cooler for LNG generators suitable for extremely cold environments. Background Technology

[0002] In the production processes of many industrial sectors, a large amount of waste heat is generated. In order to prevent the system from being affected by overheating, it is usually necessary to remove this heat in a timely manner and transfer it to the natural environment to ensure the normal operation of the production process. As a heat exchange device, the cooler can perform the functions of heat removal, exchange and cooling. Coolers are widely used in plastic machinery, hydraulic equipment, air compressors, thin oil lubrication systems, hydraulic couplings, metallurgy, chemical industry, mining, power equipment and other industries. The air-water composite cooler for LNG generators is a high-efficiency cooling device. By combining air cooling and water cooling, it can comprehensively ensure the stable operation of the generator.

[0003] Existing air-water combined coolers for LNG generators are widely used. They use a combination of air cooling and water cooling to cool the hot air generated by the generator. However, for generators used in extremely cold environments, existing devices usually cannot utilize the low temperature of the extremely cold environment to dissipate heat from the generator. Therefore, to address the above problem, an air-water combined cooler for LNG generators suitable for extremely cold environments is proposed. Utility Model Content
