Description

[0002] With the development of the times, more intelligent and electrical devices are involved in the daily use of furniture. These devices are often used in combination with furniture products. Intelligent and electrical devices that work for a long time (such as the driving motor of a massage chair) will generate high temperatures, and a heat dissipation device is required to assist in the work. The chair frame can directly be used as a heat dissipation material for heat dissipation. The copper-aluminum composite material has excellent heat dissipation performance and corrosion resistance. After a cold water channel is set on the chair frame, the corrosion resistance and heat dissipation of the chair frame can be guaranteed, and it is more beautiful than traditional copper materials. The bonding layer of the copper-aluminum composite tube material is formed by the mutual diffusion of the aluminum inner layer and the copper outer layer.
