Description
Technical Field
[0001] The utility model relates to the technical field of machine tool equipment, in particular to a heat dissipation device for machine tools. Background Art
[0002] In the field of machine tool processing, the performance and stability of the drilling motor as a core power component directly affect the processing efficiency and quality of the machine tool. However, the drilling motor will generate a lot of heat during long-term operation. If this heat cannot be dissipated in time and effectively, it will cause the motor temperature to rise, which will affect its performance, and may even cause failure or damage, shortening the service life of the motor. The heat dissipation method in the relevant technology mainly relies on natural convection heat dissipation, that is, taking away the heat through air flow. Although this method is simple, for high-power and high-workload drilling motors, its heat dissipation efficiency is often difficult to meet the requirements. In addition, the structural design of the heat sink is relatively simple, and the heat dissipation area is limited, resulting in unsatisfactory heat dissipation effect. In some applications, there are also problems such as the heat sink and the motor are not in close contact, and the heat conduction efficiency is low, which further affects the stable operation of the motor. In addition, there is a lack of real-time monitoring of the motor temperature, and it is impossible to take effective heat dissipation measures in time when the temperature exceeds the standard, which causes the motor to run for a long time in a high temperature environment, increasing the risk of failure. In view of this, it is necessary to improve the current heat dissipation device to solve the above problems;
