Abstract

The invention belongs to the technical field of robot thermal management, and particularly relates to a robot large-torque joint power-source-free intelligent temperature control integrated module. The module is designed based on a joint integrated module, efficient export of heat generated by a joint core heat source is achieved through independent phase change circulation of a working medium in the intelligent temperature control module, and the temperature stability and operation reliability of the joint under the high-load working condition are remarkably improved. The heat dissipation module does not need external power sources such as a fan and a pump completely, and is driven only by working medium phase change and natural heat dissipation, so that the system architecture is simplified fundamentally, the energy consumption is reduced, and the strict requirements of robot joints for compact space are met. According to the integrated module, the heat dissipation module is deeply integrated to the power unit, the external skin of the robot is ingeniously used as an ultimate heat dissipation interface, extremely high space utilization efficiency and structural compactness are achieved, and an efficient, passive and reliable intelligent temperature control solution is provided for the large-torque joint of the robot.
