NOVELTY - A graphene rotational flow heat exchanger, comprising a box body and a rotational flow pipe, wherein the cyclone tube is arranged inside the box body, the rotational flow pipe by a separating plate is rolled into a spiral, comprising a spiral-flow pipe A and a rotational flow pipe B, the rotational flow pipe A and pipe B between common the separator, rotation of said rotational flow pipe A and pipe B to the opposite, and the connection place of the two is curved surface; the clapboard is graphite plate. The utility model claims a graphene spiral heat exchanger is spiral flowing fluid, fluid has strong scouring function to tube wall under the action of centrifugal force, thus not suitable for scaling. and this product adopts graphene as clapboard of heat exchanger in the heat exchange process than other product heat exchange energy saving 30-50 % of high heat transfer coefficient. The product unit volume has large heat transfer area (about 1.4 times) of the light tube heat exchanger high total heat transfer coefficient, thus greatly reduces the floor area.
