Abstract

The invention discloses an intelligent driver, belonging to the technical field of intelligent drivers. On the outer side of the bottom of the second heat dissipation pipe, the head and tail of the second heat dissipation pipe are connected to form a circulation pipe, and the upper ends of the two sides of the second heat dissipation pipe are connected with the first heat dissipation pipe. There is a working fluid inside the second radiator pipe. The liquid working fluid volatilizes into a vapor state when heated, and is blown by a fan, so that the vapor working fluid moves upward to the cooling fins and is converted into liquid when it is cooled, and then flows into the lower surface of the cooling fins. In the second heat pipe, the heat is absorbed and converted into a vapor state, and the cycle is repeated to form a liquid-vapor circulation to take away the heat, so as to ensure that the driver can dissipate heat efficiently, with fast heat dissipation and good effect.
