Description

Solar cooling distribution box

technical field

The invention relates to a distribution box, in particular to a distribution box which utilizes a solar electric fan to dissipate heat.

Background technique

There are generally cooling holes on the outdoor distribution box. In order to improve the cooling efficiency of the distribution box, people will install a fan in the distribution box to blow out the high-temperature air in the distribution box. However, the disadvantages of this design are: 1. It needs to provide additional working power for the fan; 2. The fan usually runs 24 hours a day, which consumes electricity. After long-term work, electric workers have found that for outdoor distribution boxes, the temperature is lower at night, and the heat dissipation effect is often better. However, when exposed to sunlight during the day, the temperature of the metal box of the distribution box is higher, which is not conducive to heat dissipation. That is to say, if fans are used for heat dissipation, as long as the heat dissipation efficiency of the distribution box can be enhanced during the day, it is not necessary to run 24 hours a day.

Detailed ways

The technical solutions of the present invention will be described in further detail below through specific implementation methods.

Example 1

As shown in Figures 1, 2 and 3, a solar heat dissipation distribution box includes a box body 1, a solar panel 2 arranged on the top of the box body 1 and an electric fan installed in the box body 1 , wherein at least two air outlets 3 are opened on the side wall of the box body 1, the electric fan is set corresponding to one of the air outlets 3, and the solar cell panel 2 is electrically connected to the electric fan. The advantage of this design is: during the day, the solar panel 2 generates electricity under sunlight, and the electric fan works to blow out the hot air in the box body 1, which speeds up the air circulation in the box body 1 and effectively solves the problem caused by sunlight during the daytime. The problem of excessive temperature in the distribution box caused by irradiation, and the use of solar energy avoids providing additional power for the electric fan, which is energy-saving and environmentally friendly.

Example 2

As shown in FIG. 1 , the solar panel 2 is the top wall of the box 1 . This design provides a solution for integrating the solar cell panel 2 with the box body 1. During manufacture, an opening may be reserved on the upper part of the box body 1, and the solar cell panel 2 may be installed in the the opening.

Example 3

The difference between embodiment 3 and embodiment 2 is that, as shown in FIG. 2 , the solar battery panel 2 is installed above the top wall of the box body 1 through a mounting bracket. This design makes the solar cell panel 2 not in direct contact with the top wall of the box body 1, and has two advantages: A. The solar cell panel 2 plays a sunshade effect, so that the top wall avoids sunlight B. The solar panel 2 generally has a higher temperature when it is working, and not directly contacting the top wall is conducive to reducing the temperature in the box 1.

Example 4

The difference between embodiment 4 and embodiment 2-3 is that: as shown in Figure 2, the solar panel is installed above the top wall of the box through a universal joint, and the upper and lower ends of the universal joint are respectively installed In the middle of the solar panel 2 and the top wall of the box 1 . The reason for this design is that since the installation orientation and orientation of the outdoor distribution box are affected by its environmental location conditions, the installation methods of different orientations make the illumination surface on the distribution box different, so in order to make the solar panel 2 receive light. The area is maximized, so this design is made. The working process is: after the electrician installs the distribution box, according to the direction of the field illumination surface, the solar panel 2 is turned and tilted to the side facing the sun through the universal joint, so that the solar panel 2 can The largest area receives sunlight during the day to improve power generation efficiency.

Example 5

The difference between Embodiment 5 and Embodiments 1-4 is that: the tuyere 3 is set on a pair of opposite side walls of the box body 1, one of the tuyere 3 is set on the upper part of one of the side walls, and the other The air outlet 3 is provided at the lower part of the other side wall, and the air outlet of the electric fan is set corresponding to the upper air outlet 3 . The benefit of this design has two points: A. because hot air always will rise, so described electric fan is installed in the described tuyere 3 place that is positioned at the top, is conducive to blowing out the hot air of the upper part in the box body 1. Box 1; B. The electric fan is installed on the upper part of the tuyere 3 and is relatively close to the solar panel 2, which is conducive to reducing the length of the connecting line between the solar panel 2 and the electric fan, so as to avoid Too long wiring will affect the work of components in the distribution box.
