W-type finned heating pipe cooling effect, high thermal efficiency, is widely used in the oven, bake, heating, air heating and other places. It is made of high quality stainless steel, modified protactinium oxide powder, high electric resistance alloy wire, stainless steel heat sink material, made by advanced production equipment and technology, in general element surface wound metal fins, compared with the normal component cooling area expanded 2 to 3 times. Allowed fin element surface power loading is 3 to 4 times the normal element. Due to the length of the element is shortened, making itself the heat loss is reduced, at the same power conditions, with heating up fast, even heating, thermal performance, high thermal efficiency, long service life, heating devices, small size, and low cost. According to user requirements for the rational design, easy to install. Products in machinery manufacturing, automotive, textile, food, household appliances and other industries, particularly in the air curtain air conditioner industry has been widely used.
