Desciption

The wing radiator consists of three rows of paratactie screw wing pipe mainly,The paratactic screw wing pipe is made through winging O.5x1Omm of steel belt onto 18mm steel pipe and then zine hot galvaniaed ,It can also be made with ful stainless steel pipe and belt.Model SRL radiator is made of steel pipe and aluminum belt through rolling,Its radiator area of the same length is more than Model SRZ.
Being adopted mechanical wound piece,the contacting area between radiating wing piece and radiating pipe is large and its property of heat conducting is good and stable. The resist for air passing is small. The effect of heating or cooling air can be realized through heat condition between wing on steel pipe and air in the gaps of wings.
