At distribution equipment operation in-process, each electrical element among the distribution equipment can produce a large amount of heats usually, and current distribution equipment's heat is generally through the box natural loss of metal material to external world, and the radiating effect is not good enough, leads to the inside temperature rise of distribution equipment's box to influence electrical element's normal operating.
Therefore, the embodiment of the application provides a heat dissipation box and power distribution equipment thereof, which can effectively improve the heat dissipation effect of each electric element in the heat dissipation box so that the power distribution equipment can normally operate at a proper temperature.
Referring to fig. 1 to 3 together, the heat dissipation box provided in the present application may be used to accommodate an electrical component 30, and includes a box body 10, a heat dissipation fan 20, and a flow guiding assembly 40 (for convenience of illustration, a flow guiding baffle 45 belonging to a portion of the flow guiding assembly 40 is labeled 40 in fig. 2), where the box body 10 has an inner cavity 100, the inner cavity 100 is a cavity formed by the box body, the inner cavity 100 may be used to accommodate the electrical component 30, and the electrical component 30 is placed in the cavity 100 and may be fixed to the box body 10, so that the electrical component 30 can be stably placed in the inner cavity 100. The heat dissipation fan 20 may be connected to the box 10, for example, the heat dissipation fan 20 may be connected to the box 10 by a fastener or a snap, etc. (i.e., the heat dissipation fan 100 may be mounted on a sidewall forming the inner cavity 100), and the heat dissipation fan 20 may be configured to generate an air flow flowing into the inner cavity 100, and when two sides of the heat dissipation fan 20 are respectively facing the inner cavity 100 and the heat dissipation fan 20 rotates away from the inner cavity 100, the heat dissipation fan 20 may discharge air outside the inner cavity 100 into the inner cavity 100, thereby forming an air flow in the inner cavity 100. The deflector assembly 40 may be disposed in the interior 100 of the housing 10, and the deflector assembly 40 may be configured to direct airflow such that the airflow may flow through the electrical components 30 in the interior 100. The side wall of the case 10 may be provided with a heat radiating hole 101, and the heat radiating hole 101 communicates with the inner cavity 100, and the heat radiating hole 101 is used for allowing the airflow passing through the electrical part 30 to be exhausted out of the inner cavity 100 of the case 10.
In a specific application, when the heat dissipation box of the present embodiment is applied to accommodate the electrical component 30, the electrical component 30 generates a large amount of heat during the operation process, and the heat dissipation box of the present embodiment can utilize the heat dissipation fan 20 to generate an airflow flowing into the inner cavity 100, and the airflow is guided by the flow guiding assembly 40 in the inner cavity 100 of the box body 10, so that the airflow can sufficiently flow through the electrical component 30, the heat generated by the electrical component 30 is taken away by the airflow, and the heat is taken out of the inner cavity 100 of the box body 10 through the heat dissipation holes 101 on the side wall of the box body 10. Therefore, the heat of the electrical components 30 can be reduced and concentrated in the box body 10, the temperature in the heat dissipation box is obviously reduced, the technical problem that the heat dissipation effect of the power distribution equipment is poor in the prior art is solved, the heat dissipation effect of the power distribution equipment is effectively improved, and the electrical components 30 in the heat dissipation box can normally run at the proper temperature.
As an alternative embodiment of this embodiment, please refer to fig. 4 and 5, the flow guiding assembly 40 includes two first flow guiding plates 43, the first flow guiding plates 43 can guide the airflow in the inner cavity 100, and the two first flow guiding plates 43 can be inclined toward each other, that is, one ends of the two first flow guiding plates 43 are close to each other, and the other ends are far away from each other, so that the two first flow guiding plates 43 can form a horn-shaped structure, and the horn-shaped structure formed by the two first flow guiding plates 43 guides the airflow, so that the airflow can sufficiently flow through the electrical component 30, thereby improving the heat dissipation effect.
Specifically, the horn structure may have a closed opening and an open opening, wherein the closed opening and the open opening are respectively located at ends of the horn structure, a size of the closed opening is larger than a size of the open opening, a linear distance between the two first air deflectors 43 gradually increases from the closed opening to the open opening, an air outlet of the heat dissipation fan 20 may face the inner cavity 100 of the box 10, and an air inlet of the heat dissipation fan 20 faces the outside of the box 10, so that the heat dissipation fan 20 may converge low-temperature air outside the box 10 to form a low-temperature air flow and input the low-temperature air flow into the inner cavity 100 of the box 10, and the indicated low-temperature air may be air with a temperature lower than that in the inner cavity 10, or the like. The closing opening of the horn-shaped structure can be communicated with the air outlet of the cooling fan 20, so that the airflow generated by the cooling fan 20 can enter the horn-shaped structure in a centralized manner; the opening of the horn-shaped structure may be disposed right opposite to the electrical component 30 in the inner cavity 100, so that the airflow generated by the heat dissipation fan 20 passes through the electrical component 30 smoothly after passing through the horn-shaped structure, where smooth passing means that the airflow blocks a part of the airflow from swirling to form a vortex under the action of the first flow guide plate 43, so that the part of the airflow that would swirl without the action of the first flow guide plate 43 can also pass through the electrical component 30. With such a design, the two horn-shaped first air deflectors 43 can concentrate and guide the air flow generated by the heat dissipation fan 20 to the electrical component 30, thereby improving the utilization rate of the air flow of the heat dissipation fan 20 and improving the heat dissipation effect of the electrical component 30.

When the first air deflector 43 guides the air flow of the heat dissipation fan 20 toward the electrical component 30, a part of the air flow may flow toward the side wall of the box 10, and at this time, the second air deflector 44 connected to the side wall can guide the part of the air flow toward the electrical component 30, thereby further improving the heat dissipation effect of the electrical component 30.
