Problems solved by technology

[0002] The distribution box for power engineering contains a large number of electrical components. The work of electrical components will generate a lot of heat. If the heat is not discharged in time, it will easily cause the electrical components to be burned and damaged. At the same time, this type of distribution box should also have the function of dustproof and moisture-proof Therefore, it is difficult to make a distribution box for power engineering that takes into account heat dissipation, dustproof and moisture-proof, especially for indoor use.
[0003] At present, the distribution boxes on the market usually have ventilation holes on the box wall and are equipped with cooling fans to dissipate heat. The dustproof effect is poor; The efficiency is low, and the phenomenon of moisture in the meter box is easy to appear

Embodiment 1

[0033] see Figure 1-7, a power distribution box with good heat dissipation effect for power engineering, comprising a box rear wall plate 1, a moisture-proof cooling plate 2, a split water supply device 3 and a water pump 4, the moisture-proof cooling plate 2 includes a hollow heat conducting plate 21, a rectangular wiper frame 22 and The inlet and outlet pipe fittings 23, the rear surface wall of the hollow heat conduction plate 21 and the inner side of the box rear wall plate 1 are distributed in parallel. For the heat in the distribution box, the split water supply device 3 cooperates with the water pump 4 to provide circulating water to the hollow heat conduction plate 21. The rectangular wiper frame 22 is set outside the hollow heat conduction plate 21, and the rotation axis of the hollow heat conduction plate 21 passes through the rectangular shape at the same time. The middle part of two parallel long boards 221 on the wiper frame 22. The rectangular wiper frame 22 is ...

Embodiment 2

[0035] see figure 2 The difference from Example 1 is that a group of grooves 212 uniformly distributed in the circumferential direction are arranged on the surface of the hollow heat conduction disk 21 away from the rear wall plate 1 of the box, and a group of grooves 212 are arranged in a row and distributed along the radial direction. The single groove 212 is waist-shaped and its length direction is perpendicular to the radial direction of the hollow heat conducting plate 21. One end in the groove 212 is rotatably connected with a heat-absorbing tube 2121, and a torsion spring is arranged at the rotating connection, and one end of the heat-absorbing tube 2121 passes through a soft The tube communicates with the inner cavity of the hollow heat conducting plate 21, and one of the wiper rubber plates 2211 is provided with a U-shaped notch 22111 used in conjunction with the heat absorbing pipe 2121. When the hollow heat conducting plate 21 rotates, the heat absorbing pipe 2121 c...

Abstract

The invention discloses an electric power engineering-oriented distribution box with a good heat dissipation effect. The distribution box comprises a box rear wall plate, a moisture-proof heat dissipation disc, a shunt water supply device and a water pump; the moisture-proof heat dissipation disc comprises a hollow heat conduction disc, a rectangular water scraping frame and an incoming and outgoing pipe fitting. In the distribution box of the invention, a hollow heat conduction disc is arranged in the distribution box, the heat conduction disc is rotatably arranged; the rectangular water scraping frame is arranged outside the heat conduction disc; the rectangular water scraping frame sleeves the hollow heat conduction disc; the rotation axis of the hollow heat conduction disc simultaneously penetrates through the middle parts of two parallel long plates on the rectangular water scraping frame; the rectangular water scraping frame is vertically distributed; water scraping rubber platesare fixedly arranged on the opposite sides of the two long plates; after cold water is introduced into the hollow heat conduction disc; the hollow heat conduction disc cools the interior of the distribution box; condensed water drops on the surface wall of the hollow heat conduction disc are collected by the rectangular water scraping frame and gathered downwards, then the condensed water drops are discharged outside through a guide pipe; and therefore the damp-proof effect can be achieved while heat exchange is improved.
