NOVELTY - The utility model claims a fin heat exchanger with strong corrosion resistance. It comprises an upper protecting plate, a lower protecting plate, a left and right fixing plate, a radiating pipe, an aluminium foil fin, a liquid distributing head, a gas collecting pipe; multiple groups of aluminium foil fins parallel to the left and right fixing plates are arranged between the left and right fixing plates; a plurality of radiating pipes are set between the upper and lower protective plates; each radiating pipe is horizontally coiled and laminated; the radiating pipe is inserted into the round hole of the aluminium foil fin and passes through the flange pipe sleeve; the liquid dividing head is connected with the inlets of the multiple radiating pipes; the gas collecting pipe is connected with the outlet of the multiple radiating pipes; several drain holes are opened on the upper and lower guard plates; the positive and negative surfaces of the aluminium foil fin; the inner surface and the outer surface of the flange sleeve, and the outer surface of the radiating pipe and the aluminium foil fin are coated with graphene polymer composite anti-corrosion coating. The fin heat exchanger uses graphene polymer composite anti-corrosion coating and the upper and lower protective plate is provided with a drain hole, which can solve the problem that the environment-friendly industry caused by salt mist content of the air in the air and condensed water with high salt concentration caused by the corrosion problem.
