Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a distribution box with good heat insulation and high cooling efficiency. Background Art

[0002] The distribution box is a key mechanism for modern power transmission. It is used to assemble electrical appliances for power distribution, so that electric energy can be distributed to lower-level distribution equipment in different locations, ensuring the reasonable distribution and output of power between power facilities. When the distribution box is in use, the electrical components installed inside it will emit a lot of heat. If the heat in the distribution box is not dissipated in time, the electrical components in the distribution box will be easily damaged by high temperature. In the existing patent application with application number CN202220228978.3, a ventilation and heat dissipation distribution box is proposed, which only exchanges the hot air in the distribution box with the air outside the distribution box through a heat dissipation fan, so as to achieve the purpose of dissipating the heat inside the distribution box. However, in hot weather, when the air temperature outside the distribution box is high, the effect of using the heat dissipation fan to exchange the air inside and outside the distribution box to achieve the purpose of cooling the inside of the distribution box will be poor, so that the temperature inside the distribution box is still high, and the electrical components in the distribution box are easily burned by high temperature. At the same time, it does not have a corresponding heat insulation structure, so that in hot weather, the high temperature outside is easily transferred to the distribution box through the box body, and the temperature inside the distribution box is high. Therefore, a distribution box with good heat insulation and high cooling efficiency is needed to solve the above problems. Utility Model Content

By arranging the thermal insulation structure 2 on the inner wall of the distribution box body 1, the aerogel felt layer 8 and the rock wool layer 9 on the thermal insulation structure 2 can effectively isolate the external heat, so that in hot weather, the external heat can be prevented from being transferred into the distribution box body 1 through the distribution box body 1, thereby effectively reducing the temperature in the distribution box body 1 in hot weather, so that the electrical components in the distribution box body 1 are not easily burned by high temperature.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a heat dissipation fan 3 is fixedly installed on one side wall of the distribution box body 1 and the insulation structure 2. The heat dissipation fan 3 is composed of a base frame 10, a fan body 11 and a No. 1 protective net 12. The fan body 11 is fixedly installed on the inner wall of the base frame 10. There are two No. 1 protective nets 12 and they are fixedly installed at the inner and outer ends of the base frame 10 respectively. The base frame 10 is fixedly installed in the No. 1 mounting groove 6 and the No. 2 mounting groove 7. A cooling structure 4 is fixedly installed on the other side wall of the distribution box body 1 and the insulation structure 2. The cooling structure 4 is composed of a heat exchange metal frame 13, a heat exchange fin 14, a No. 2 protective net 15, a mounting frame 16, a semiconductor cooling sheet 17 and a heat sink 18. The heat exchange fin 14 is fixedly installed on the inner wall of the heat exchange metal frame 13. There are two No. 2 protective nets 15 and they are fixedly installed at the inner and outer ends of the heat exchange metal frame 13 respectively. There are two mounting frames 16 and they are symmetrically fixedly installed on the outer wall of the heat exchange metal frame 13.

During use, the aerogel felt layer 8 and the rock wool layer 9 on the insulation structure 2 can effectively isolate the external heat, so that in hot weather, the external heat can be prevented from being transferred to the distribution box body 1 through the distribution box body 1, thereby effectively reducing the temperature in the distribution box body 1 in hot weather, so that the electrical components in the distribution box body 1 are not easily burned by high temperature; and when it is necessary to discharge the hot air in the distribution box body 1 to cool down the distribution box body 1, the heat dissipation fan 3 can be started, and at this time, the fan body 11 will work to discharge the hot air in the distribution box body 1. The external air will enter the distribution box body 1 through the heat exchange metal frame 13 on the cooling structure 4. At the same time, the cooling structure 4 can be started. At this time, the low temperature generated by the cold end of the semiconductor refrigeration plate 17 on the cooling structure 4 will cool the heat exchange metal frame 13 and the heat exchange fins 14, thereby making the temperature of the heat exchange metal frame 13 and the heat exchange fins 14 lower. At this time, the air passing through the heat exchange metal frame 13 will exchange heat with the heat exchange metal frame 13 and the heat exchange fins 14, thereby making the temperature of the air entering the distribution box body 1 lower. Finally, the distribution box body 1 can be better cooled, so that the cooling efficiency in the distribution box body 1 is higher.
