Description

Technical Field

[0001] The utility model belongs to the field of fire prevention of electrical boxes, and specifically relates to a fireproof electrical box structure. Background Art

[0002] An electrical box is a device for placing and wiring electrical components in current electrical appliances. It can not only organize wires but also protect electrical components, thus ensuring its long-term and stable use. However, after a long time, new problems have emerged. Since electrical components operate at high speeds during the operation of the electrical appliance, the temperature of the electrical components will gradually increase. However, due to the current design of the electrical box, its heat dissipation effect is poor, which will cause the electrical components to operate in a high-temperature environment for a long time, resulting in a shortened service life, easy occurrence of failures, and even possible occurrence of open flames, causing a certain fire. Therefore, how to effectively improve the fire prevention function of the electrical box is an urgent problem to be solved at present. Content of the Utility Model

The cavity below the heat conduction sheet can place electrical components. Through-wire slots are respectively arranged at both ends of the bottom of the box body. Several heat dissipation fins are evenly arranged on the top of the heat conduction sheet. A heat dissipation fan is arranged above the heat dissipation fins in the box body. The heat dissipation fan is electrically connected and powered through an electrical controller or a processor. An air inlet pipe is arranged at the top of the box body. Both sides above the heat conduction sheet in the upper middle part of the box body are respectively communicated with one end of an air outlet pipe.

[0006] For a fireproof electrical box structure as described above, the box body is successively composed of a first fireproof and flame-retardant layer, a metal support layer, and a second fireproof and flame-retardant layer from the inside to the outside.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0015] A fireproof electrical box structure includes a box body 1. Inside the box body 1, a heat conducting sheet 2 is arranged in the middle. The cavity below the heat conducting sheet 2 can place electrical components. At both ends of the bottom of the box body 1, a wire routing through slot 3 is respectively arranged. On the top of the heat conducting sheet 2, several heat dissipation fins 4 are evenly arranged. Above the heat dissipation fins 4 in the box body 1, a cooling fan 5 is arranged. The cooling fan 5 is electrically connected and powered through an electrical controller or a processor. An air inlet pipe 6 is arranged on the top of the box body 1. On both sides above the heat conducting sheet 2 in the upper middle part of the box body 1, they are respectively communicated with one end of an air outlet pipe 7. In the present utility model, after the electrical appliance is started, that is, after the electrical components operate, the electrical controller or the processor controls the cooling fan 5 to start, and the high temperature generated by the operation of the electrical components is quickly discharged through the heat conducting sheet 2 and the heat dissipation fins 4 and through the air outlet pipe 7. Moreover, the air inlet pipe 6 avoids the generation of negative pressure in the upper part of the box body 1, ensuring the long-term stable use of the box body 1.

[0016] Specifically, the box body 1 of the present embodiment is successively from the inside to the outside a first fireproof and flame-retardant layer 8, a metal support layer 9, and a second fireproof and flame-retardant layer 10. In the present utility model, the metal support layer 9 plays a supporting role for the box body 1, and the first fireproof and flame-retardant layer 8 and the second fireproof and flame-retardant layer 10 can effectively improve the fire resistance and heat resistance performance of the box body 1, effectively improving the fire prevention ability.

[0017] Specifically, since the cooling fan 5 is used from the start to the shutdown of the electrical appliance, its service life is relatively low. At the same time, only when the electrical components run at high speed will a large amount of heat be released, so heat dissipation may not be required during normal operation, and the cooling fan 5 does not need to be always on. To overcome the above problems, a temperature sensor 11 is arranged below the heat conducting sheet 2 in the present embodiment. The temperature sensor 11 is electrically connected to the electrical controller or the processor. By monitoring the temperature in real time through the temperature sensor 11, the cooling fan 5 is only turned on when the temperature is higher than the specified temperature, thus ensuring the long-term stable use of the cooling fan 5.

[0018] Furthermore, a gas filter screen 12 is arranged at the top of the air inlet pipe 6 in the present embodiment. In the present utility model, through the gas filter screen 12, sundries in the air are effectively prevented from entering the box body 1 and accumulating, ensuring the normal use of the present utility model.

[0019] Even further, the other end of the air outlet pipe 7 is located outdoors or outside the whole electrical appliance.

[0020] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
