Embodiment 1

[0035] see Figure 1-4, a high-frequency anti-aging cooling device for a closed power distribution cabinet, including a cylinder-type booster tube 1 and a pressure switching cooling part 2, wherein the role of the cylinder-type booster tube 1 is to provide steam pressure, and the pressure switching cooling part 2 has The effect of changing the pressure; specifically, the pressure switching cooling part 2 is installed at the bottom of the cylinder type booster tube 1, and the outer cylinder 11 on the cylinder type booster tube 1 is provided with a laser high-frequency heater 3, and the outer cylinder 11 The top is fixedly connected with a heating rod 111 distributed on the same axis. The high-frequency spiral tube 31 on the laser high-frequency heater 3 is sleeved on the outside of the heating rod 111. Through the above-mentioned setting, an evaporation medium, such as water, is added to the inner cavity of the outer cylinder 11. , the laser high-frequency heater 3 provided und...

Embodiment 2

[0037] see figure 2 and image 3 , and the difference from Embodiment 1 is as follows, the cooling tube 22 has a reset function, specifically, the bottom of the cooling tube 22 is fixedly connected with a return spring 222, and the top of the return spring 222 is fixedly connected with the bottom of the sealing plate 221. When starting to enter the cooling tube 22, due to the existence of pressure, the sealing plate 221 is pushed down, the return spring 222 is compressed, and the pressure set by the return spring is lower than the critical pressure of the refrigerant. An exhaust valve 223 is installed on one side, the exhaust valve 223 is opened to relieve pressure, and the return spring 222 is stretched, so that the sealing plate 221 can push the gaseous refrigerant into the lower hemispherical cavity of the spherical shell 211, at this time the control dial 212 rotates, and the gaseous refrigerant is resent to the upper hemispherical chamber of the spherical shell 211; the...

Embodiment 3

[0039] see figure 2 and Figure 5 The difference from Embodiment 1 is that the outer periphery of the spherical housing 211 is fixedly connected with a mounting plate 2111, and the function of the mounting plate 2111 is to connect with the outer wall of the power distribution cabinet to fix the cooling device. The mounting plate 2111 All offer vacuum cavity 4 in the rotating disk 212, have the effect of heat insulation.

Abstract

The invention discloses a high-frequency anti-aging cooling device for a closed power distribution cabinet, which includes a cylinder-type booster cylinder and a pressure switching cooling unit, the pressure switching cooling unit is installed at the bottom of the cylinder-type booster cylinder, and the cylinder A laser high-frequency heater is arranged on the outer cylinder on the type pressurized cylinder. In the present invention, by setting a cylinder-type pressurized cylinder, a laser high-frequency heater is arranged on the cylinder-type pressurized cylinder to realize the rapid generation of steam pressure in the cylinder-type pressurized cylinder, and the ball valve-type switching combination in the pressure switching cooling part is installed Refrigerant, the vapor pressure can compress and liquefy the refrigerant, and then the turntable on the ball valve switching combination turns over to guide the liquefied refrigerant into the low-pressure cooling tube. The cooling tube is installed inside the power distribution cabinet, thus the liquefied refrigerant When the pressure environment is reduced to only the critical pressure, it will vaporize and absorb heat, and then realize the cooling of the inside of the power distribution cabinet. The power distribution cabinet can be designed as a closed type, which has the effect of anti-aging.

Description

technical field [0001] The invention relates to the technical field of anti-aging of power distribution cabinets, in particular to a high-frequency anti-aging cooling device for a closed power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. , and the existing power distribution cabinets are usually ventilated structures, with heat dissipation devices installed inside, which is prone to internal pollution of the power distribution cabinet, and the function of the heat dissipation device is single, and the heat dissipation effect is poor, so it is easy to accelerate the circuit and electrical components. Ageing. [0003] At present, the common heat dissipation device is a heat dissipation fan, combined with the heat dissipation holes provided on the power distribution cabinet to achi...
