1. The advantage of the L-type winding tube is that the working conditions are relatively stable and the cost is low. Disadvantages: The operating temperature should not be too high, too high will loose around the film, the clearance is prone to corrosion, cleaning is harder.
2. The advantages of bimetal fin tubes are: stable working conditions, working temperature of up to 280 ℃, strong anti-corrosion performance, easy cleaning. Disadvantage: The cost is high.
3. The advantages of wearing slice fin tube are: the whole rigidity is good, anti-seismic, save water, heat dissipation performance is good. Disadvantage: High cost.
