Multi-angle openings for heat dissipation, there are heat dissipation holes on the side, back and bottom of the fuselage to ensure work efficiency. Using intelligent chip temperature control and precise control by microcomputer, so that the heating area is evenly heated and the temperature is controlled accurately. High-power aluminum plate heating substrate, high-efficiency heat pipe, uniform heat transfer, high conduction efficiency. Anti-scalding protection of aluminum plate wrapping, effectively absorb heat of aluminum plate and prevent heat from flowing into the host.
