Ball screw capable of thermal dissipation based on thermoelectric cooler

摘要

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.

1. A ball screw capable of thermal dissipation, comprising a screw rod, a screw nut, and a plurality of balls located between the screw rod and the screw nut, wherein the screw nut comprises a mounting surface and the ball screw further comprises a thermoelectric cooler having a heat-absorptive surface and a heat-dissipative surface, the heat-absorptive surface being adhered to the mounting of the screw nut,
wherein the mounting surface is planar, and both of the heat-absorptive surface and the heat-dissipative surface of the thermoelectric cooler are planar, and wherein the mounting surface is recessed downward from an external surface of the screw nut for a predetermined depth that prevents the heat-dissipative surface from being higher than the external surface of the screw nut.
