LNG (liquefied natural gas) vehicle-mounted cold-radiating refrigerator with cold-storage top plate

Abstract

An LNG (liquefied natural gas) vehicle-mounted cold-radiating refrigerator with a cold-storage top plate comprises an LNG storage tank and a vehicle-mounted refrigerator. The LNG storage tank is connected with the vehicle-mounted refrigerator through a connecting pipeline. The vehicle-mounted refrigerator comprises an outer shell, an inner shell, a heat exchanger, a cold plate, a sliding drawer and a cold-storage water basin. The inner shell is provided within the outer shell. The heat exchanger, the cold plate, the sliding drawer and the cold-storage water basin are disposed within the inner shell. The cold plate is disposed below the heat exchanger and adjacent to the heat exchanger. The sliding drawer is disposed below the cold plate. The cold-storage water basin is disposed below the sliding drawer. Cold released by LNG in the gasification process is fully utilized, the cold-storage water basin releases the cold during stopping of an engine, and full-time refrigeration of the refrigerator is achieved; power is saved in the process, and significance is brought to cold recovery, energy saving and emission reduction, environment protection and the like.

Description

technical field [0001] The invention relates to the field of refrigerating mechanical devices, in particular to an LNG vehicle-mounted cold-storage type roof radiation cooling refrigerator. Background technique [0002] As a clean and efficient energy source, natural gas is of great significance to the prevention and control of air pollution in my country. In recent years, my country's natural gas consumption has grown rapidly. As a liquid form of natural gas, LNG (Liquefied Natural Gas) is a liquid formed when natural gas is purified and cooled to below -162 °C. Its existence increases the flexibility of natural gas storage, transportation and utilization. properties, expanding the scope of application of natural gas. In the past two years, the utilization of LNG in the transportation field has become a highlight in the development of the natural gas industry. The National Natural Gas Development "Twelfth Five-Year Plan" clearly encourages efficient natural gas utilization...

For heavy-duty trucks, the drivers are on the go all the year round, the working conditions are difficult, and the diet is limited. However, truck drivers often hope to have a convenient diet during long-distance transportation. At present, it is unrealistic to carry food with the truck, and it is easy to spoil. Having a machine that can store fresh food on the order of 3-5 days would be a welcome move for truck drivers
