The radiator is divided into radiant radiator and convection radiator according to the heat transfer mode. The convective heat dissipation of convective radiators accounts for almost 100%, sometimes called "convective current". Compared with convective radiators, other radiators radiate by convection and radiation at the same time, sometimes called "radiator".
The radiator is divided into cast iron radiator, steel radiator and other material radiator according to material quality. Other materials include radiators made of aluminium, copper, steel-aluminium composite, copper-aluminium composite, stainless steel-aluminium composite and enamel.
