Computer external heat dissipation equipment

The utility model relates to computer external heat dissipation equipment which comprises a fixing seat, a heat conduction plate is embedded in the top wall of the fixing seat, an adjusting mechanism is arranged at the bottom of the fixing seat, and the adjusting mechanism comprises a shell, a motor, a bidirectional threaded rod, a threaded sleeve, a hinge block, a connecting rod, a hinge seat and a placing plate. According to the external heat dissipation equipment for the computer, by arranging the adjusting mechanism, when the placement height of the computer needs to be adjusted, a motor can start to rotate through a control panel, the motor drives a two-way threaded rod to rotate, and the two-way threaded rod rotates to drive two threaded sleeves to move oppositely or oppositely, so that a placement plate is driven to descend or ascend; after the placing plate is adjusted to a proper height, the motor can be stopped, the computer is placed on the heat conducting plate, heat dissipation of the computer is
