Abstract

The article deals with design and design of a thin-walled heat sink for the robot control system, the measurement of the transverse roughness of the touch surfaces and the programming procedure in Autodesk Inventor 2019 software. In this software, a design of the 3D model of the heat sink generated based on power supply and NC code generation for the Fanuc control system. The production it-self carried out on the CNC Vertical Machining Center Pinnacle 2100 with this control system. The longitudinal surface roughness was measured with a Mi-tutoyo SJ 400 dredger and the measurement result was the maximum Ra = 0.69 μm and Rz = 4.1 μμm.

Highlights

The characteristic feature of the passive cooler (Fig. 1) is the ribbed and its base attached to the processor
The fan blows the air between the ribs to increase cooling efficiency. The disadvantage of this type of heat sink is the risk of damaging or destroying the fan and this result in the processor destroyed by its rising temperature
Depending on the use of bearings, we distribute fans on fan bearings that are less expensive but more susceptible to failure and fan bearings that are of better quality (Fig. 2)

Summary

Introduction

Processor manufacturers for robot control systems are constantly increasing their performance, which greatly affects the way they cooled. The fan blows the air between the ribs to increase cooling efficiency. The disadvantage of this type of heat sink is the risk of damaging or destroying the fan and this result in the processor destroyed by its rising temperature. The heat conducting paste applied to the entire surface of the processor and is fit-ted with a cooler. Most electronic components, including the processor, emit heat when it turned on This heat is undesirable for the entire robot control system, and an additional auxiliary fan installed in the entire box.
