Abstract
A ball screw capable of thermal dissipation is formed of a screw rod, a screw nut, and a plurality of balls mounted between the screw rod and the screw nut. The screw nut includes a mounting surface. A thermoelectric cooler is mounted to the screw nut and includes a heat-absorptive surface and a heat-dissipative surface. The heat-absorptive surface is adhered to the mounting surface. Accordingly, the ball screw can cool the heat down and is structurally simple and the whole weight is not increased due to the thermoelectric cooler.
