Heat dissipation device for combined power distribution equipment

Abstract

The invention discloses a heat dissipation device for combined power distribution equipment, and relates to the technical field of heat dissipation of electrical equipment. In order to solve the damping problem, the device comprises a base and a damping mechanism, a shell cover is fixed to the outer wall of the top of the base through bolts, an air outlet and four air inlets are formed in the inner walls of the two symmetrical sides of the shell cover respectively, air inlet pipes are fixedly installed on the inner walls of the air inlets, the air inlet pipes are connected with air conveying pipes through multi-way connectors, and a flow guide shell is fixedly installed on the outer wall, close to the air outlet, of the shell cover. According to the invention, a hinge connecting rod is arranged, vibration generated by the equipment can be transmitted to the mounting block, the vibration is transmitted to the damping ring, due to the fact that the included angle between the hinged connecting rod and the horizontal direction is smaller than 30 degrees, according to the triangle principle, high-frequency low-amplitude longitudinal vibration can be changed into high-frequency high-amplitude vibration, then the high-frequency high-amplitude vibration is absorbed through the second spring and the first spring, the co-vibration effect generated by the first spring and the second spring is avoided, and the damping effect is improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electric equipment, in particular to a heat dissipation device for combined distribution electric equipment. Background technique [0002] In the field of electrical equipment, various power distribution and power transmission equipment will be stored in corresponding boxes to effectively ensure their safe operation. Since the equipment is stored and installed in the corresponding box, high frequency and low amplitude noise will be generated when the equipment is working. Vibration and high noise. In order to solve this problem, most of the cabinets will be equipped with corresponding shock absorbing devices to absorb the vibration generated by the equipment. However, the vibration generated by the equipment has a high frequency and a small amplitude. It is difficult for the current shock absorbing device to achieve a good absorption effect on the basis of ensuring low cost. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: it adds a shock absorber to the equipment on the basis of heat dissipation, and the shock absorber uses a shock absorber, which does not clearly specify the type of the shock absorber, but the common type of the shock absorber is a spring Shock absorption, hydraulic shock absorption or spring-hydraulic combination shock absorption, because when the equipment is running, it generates high-frequency and low-amplitude vibrations. When only using a shock-absorbing rod parallel to the vibration direction for shock absorption, first, the spring absorbs high-frequency and low-amplitude vibrations. The vibration of the amplitude will produce a resonance effect, and the shock absorption effect is poor, and the hydraulic rod cannot quickly respond to high-frequency vibration, and the shock absorption effect is not good.
