Description

Technical Field

[0001] The invention relates to the technical field of graphite heat exchangers, in particular to a dirt removing device for a graphite heat exchanger. Background Art

[0002] Heat exchangers often use air to exchange heat and need to be exposed to the air to work. They are widely used in civil and industrial fields, such as air conditioning condensers, vehicle cooling systems, computer cooling systems, etc. The sand, dirt, dust, and floating objects in the air will enter the gaps between the heat exchangers and accumulate in the fins of the heat exchangers, reducing the heat exchange capacity, wasting energy and shortening the life of the system. Taking the air-cooled cooling system in the vehicle cooling system that is directly exposed to the outdoors as an example, the dirt that enters from the grille during driving can easily adhere to the radiator, especially in spring and autumn. Some poplar catkins, willow catkins, leaves and other debris float in the air and adhere to the radiator, which will increase fuel consumption and be accompanied by symptoms such as the air conditioner not cooling and the water temperature being high.

[0003] In the existing graphite heat exchanger dirt removal device, the graphite heat exchanger is generally immersed in water for cleaning during use. After the graphite heat exchanger is cleaned, the personnel need to take it out of the water. The sewage after cleaning is likely to cause secondary pollution to the graphite heat exchanger, affecting the dirt removal effect. Summary of the invention
