Abstract

The invention provides a corrosion-resisting air-conditioning fin material used for a marine product cultivation workshop and a preparation method thereof. The corrosion-resisting air-conditioning fin material used for the marine product cultivation workshop comprises a base layer and a first heat-conduction layer arranged on the base layer, wherein the base layer is composed of the following elements in percentage by weight: 6-7% of silicon, 1.7-1.9% of copper, 2.8-3.0% of manganese, 1.2-1.4% of iron, 0.2-0.3% of lanthanum, 0.04-0.05% of zirconium, 0.12-0.14% of strontium, 0.37-0.39% of titanium, 0.13-0.15% of vanadium and the balance of aluminum. The heat-conduction layer is made of graphene. According to the corrosion-resisting air-conditioning fin material, the strength can be more than 320MPa and the rigidity can be more than 130HB; and the corrosion rate of a salt mist test is only 0.08 microgram / square centimeter per day, and the heat conduction coefficient is more than 220W / m.K.

Description

technical field [0001] The invention relates to an air-conditioning fin material and a preparation method thereof, in particular to a heat collecting tube of a solar water heater. Background technique [0002] With the continuous development of the artificial breeding industry of seafood, the constant ambient temperature of the breeding area or the breeding workshop is an important issue that people are facing. [0003] In order to ensure that the seafood farming workshop can maintain a specific temperature, it is a routine method to use air conditioners to adjust the temperature. [0004] However, the air-conditioning fins currently used are all aluminum alloys, which not only have low strength, but also are not corrosion-resistant, and also have the defect of unsatisfactory thermal conductivity, usually around 90W / m·K, so that the thermal conductivity is poor. Pure aluminum (purity>99%) has a high thermal conductivity (>220W / m·K), but its fluidity and castability ar...
