Description

technical field [0001] The invention relates to the field of vibration equipment cooling, in particular to a structure for assisting cooling and cooling by spraying inside the vibration equipment. Background technique [0002] The electric vibration table is the key test equipment necessary for the development of aerospace (military) products such as rockets, missiles, and satellites. It is widely used in product strength checks, transportation environment testing, and reliability tests. The development of products in various industries such as trains and the verification of products under simulated working conditions. The vibration test equipment drives the moving parts through the interaction of the alternating current of the driving coil and the constant magnetic field to generate the exciting force. [0003] In medium and small direct-coupled vibration equipment, the moving parts are rigidly formed by the moving coil skeleton and the driving coil through high temperatur...

AI Technical Summary

Problems solved by technology

Direct or inductively coupled vibration equipment generally adopts the method of fan exhaust to quickly reduce the surface temperature, so as to realize the thermal balance of the surface of the driving coil or induction ring, but in the test environment of high value, strong vibration and long time, the driving coil Or the large induction current of the induction ring part causes its surface to continue to have a high temperature, causing its radial dimension to expand and increase, the original movement air gap channel is damaged, and the air gap size is correspondingly reduced, thereby reducing the cooling efficiency of the fan exhaust , it is easy to cause the failure of the moving parts, which affects the normal use of the vibration equipment. At the same time, after the induction ring on the moving parts passes through the induction current, heat is generated and accumulated rapidly, causing the surface temperature to increase, causing the induction ring to expand radially, thereby reducing the original Some heat dissipation air gaps affect the heat dissipation efficiency of the induction ring. Only the conventional air cooling heat dissipation method cannot satisfy its long-term stable working state.
