Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of a combined radiator of structural absorption and condensation for refrigerating and ice-making exhaust gas of vehicles and ships. Background Art

[0002] With the intensification of the global energy crisis and the improvement of environmental protection awareness, the waste heat recovery technology of vehicle and ship exhaust has received increasing attention. Traditional radiators often rely on a single heat dissipation method. Although absorption radiators can effectively utilize heat energy under certain working conditions, they have problems such as limited cooling efficiency and high requirements for heat source stability. Condensing radiators When dealing with high-temperature, high-flow exhaust, traditional radiators may face problems such as excessive condensation pressure and rapid consumption of heat dissipation medium. This makes it difficult for traditional radiators to fully and efficiently meet the refrigeration and ice-making needs under complex conditions of vehicle and ship exhaust, and there is a large room for improvement in energy efficiency and equipment stability. The disadvantage is that two separate fans need to be installed for cooling, which wastes energy. The temperature required for the condenser is relatively constant. The absorber can be cooled by fans or natural wind first. The wind coming out of the absorber will stabilize at a fixed value, which is very beneficial for the condenser with higher cooling requirements. Therefore, a vehicle that can efficiently integrate absorption and condensation is developed. The combined absorption and condensation radiator of the ship's tail gas refrigeration and ice making structure also saves a lot of space for the unit. Summary of the invention
