Problems solved by technology

The traditional cooling method cannot meet its heat dissipation requirements. For this reason, new heat dissipation or cooling methods such as micro-channel cooling, micro-jet cooling, and micro-heat pipe cooling have gradually emerged in the world.
The above heat dissipation or cooling methods have disadvantages such as low radiation heat dissipation efficiency, complex structure, large volume, limited space, easy to rust in places such as air conditioners, automobiles, refrigerators, etc., use a large amount of expensive copper materials, high cost, and inconvenient use.
