Abstract

The invention relates to an aluminium section heat exchanger formed by two heat conduction tubes and a plurality of aluminium section heat exchange tubes; the heat conduction tube is made of a carbon steel tube, and is provided with an opening allowing the aluminium section heat exchange tube to penetrate and fixation; a tube joint is made of carbon steel tubes; one end of the tube joint is provided with an outer thread; prepared inner threads are arranged in the tube on two ends of an aluminium section tube; the aluminium section heat exchange tube is formed by the aluminium section tube and the tube joint; the inner wall of the outer aluminium section tube is provided with inner fins, and the outer wall is provided with outer fins; a welding machine can weld and fixedly connect the openings of the two heat conduction tubes with corresponding positions of the tube joints on two ends of the aluminium section heat exchange tube, thus welding the plurality of aluminium section heat exchange tubes on the heat conduction tubes. The aluminium section heat exchanger can directly exchange heat, is high in heat conversion efficiency, can enlarge heat exchange temperature, and heat conduction coefficient can be increased by 2-5 times within same space and volume, thus enlarging heat radiation speed, improving heat energy transmission quantity, and providing energy saving environmental protection effects.

Description

technical field [0001] The invention relates to a heat exchange radiator, in particular to an aluminum profile heat exchanger. Background technique [0002] Most of the heat exchange tubes used in heat exchangers on the market are made of carbon steel. The thermal conductivity of ordinary carbon steel is 45W / m·K, and that of aluminum is 230W / m·K. However, because the sealing of the aluminum tube is not good for welding and sealing, the fixed sealing degree cannot meet the requirements of use, so the heat exchange tubes of heat exchangers on the market are not used in the products of aluminum profile tubes. The carbon steel pipe surrounds the fins on the tube with high manufacturing cost, large radiator volume, low thermal conductivity of carbon steel, large radiator volume, small heat dissipation area, and low heat energy utilization efficiency. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the prio...
