▎ 摘　　要

NOVELTY - The heat-radiator has a water inlet chamber (2) formed with a feeding port. The feeding port is screwed or screwed off through a feeding cover (3) for opening or closing the water inlet chamber. Outer surfaces of a water outlet chamber (10), a heat-radiating pipe (7) and a heat-radiating fin (8) are coated with a uniform graphene coating layer. Diameter of the feeding port is about 20 mm. The feeding cover is made of heat-insulating material such as glass. USE - Graphene-reinforced heat exchange gilled tube heat-radiator for an automobile engine. ADVANTAGE - The heat-radiator completely uses graphene with better thermal conductivity so as to improve heat exchange effect. The outer surfaces of the water outlet chamber, the heat-radiating pipe and the heat-radiating fin are coated with the uniform graphene coating layer, so that the heat is quickly transferred in air, thus improving heat-radiating efficiency and engine working performance. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene-reinforced heat exchange gilled tube heat-radiator.
