Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-4, a power supply box assembly comprises a box body 1 and two air induction sealing and opening assemblies 4;
the box body 1, the sidewall of the box body 1 is provided with an air inlet 2 and an air outlet 3 for the circulation of the gas inside and outside the box body 1;
the two air induction sealing and opening assemblies 4 are respectively arranged in the air inlet 2 and the air outlet 3;
the two air-sensing sealing and opening assemblies 4 can automatically slide towards the outer side wall of the box body 1 under the high-pressure and high-temperature state, so that the air inlet 2 and the air outlet 3 are both opened, and air on the inner side and the outer side of the box body 1 can circulate.
When the temperature of the sealed box body 1 rises under normal conditions, the pressure in the box body 1 increases, otherwise, when the temperature of the box body 1 decreases, the pressure in the box body 1 decreases, and the air induction sealing and opening assembly 4 in the device automatically opens the air passage between the air inlet 2 and the air outlet 3 by utilizing the temperature change in the box body 1 so as to facilitate the circulation of air inside and outside the box body, thereby radiating out the heat inside the box body 1, and when the generated heat inside the box body 1 is less, the air passage between the air inlet 2 and the air outlet 3 can be automatically closed by the air induction sealing and opening assembly, so that the possibility that external dust enters the box body 1 is reduced.
Specifically, as shown in fig. 4, the air inlet 2 and the air outlet 3 each include a straight opening section 5 and an inclined opening section 6, the straight opening section 5 and the inclined opening section 6 are mutually communicated, the air-sensing sealing and opening assembly is installed in the straight opening section 5, and the air-sensing sealing and opening assembly can slide along the straight opening section 5 and close or open an air passage between the straight opening section 5 and the inclined opening section 6.
The gas channel is divided into two parts through the arrangement of the straight port section 5 and the bevel port section 6, the installation of the gas sensing sealing and opening assembly 4 is facilitated by the gas channel structure of the two parts, and the closing and opening of the gas channel are also facilitated by the gas channel structure of the two parts, so that dust is prevented from entering, and dust screens are installed at the openings of the air inlet 2 and the air outlet 3.
Specifically, as shown in fig. 3-4, each of the two air induction sealing and opening assemblies 4 comprises a guide rod 41, a guide block 42 and a telescopic spring 43; the guide rod 41 is arranged in the inner cavity of the straight port section 5; a guide block 42 slidably coupled to the guide bar 41; the telescopic spring 43 is sleeved on the guide rod 41, and two ends of the telescopic spring 43 are respectively connected with the guide block 42 and the side wall of the straight section opening.
When the temperature in the box body 1 rises to a certain value, the value is the lowest temperature value of the safe work of each component in the power box body 1, the temperature rises, the pressure in the box body 1 also rises along with the temperature rise, under the pushing of the high pressure, the high-pressure gas pushes the guide block 42 in the air inlet 2 and the air outlet 3 to slide along the guide rod 41, in the sliding process, the guide block 42 continuously compresses the telescopic spring 43, the compressed telescopic spring 43 generates elastic deformation until the guide block 42 slides through the bevel section 6, at the moment, the bevel section 6 is communicated with the straight port section 5 to form an air passage for the internal and external air circulation, the external air with lower temperature enters through the air inlet 2 and flows out through the air outlet 3, so that the exchange of the heat of the internal and external air is realized, after the temperature drops to a certain extent, the thrust generated by the elastic telescopic spring 43 is gradually larger than the thrust generated by the air in the inner cavity of the box body 1, the guide block 42 gradually moves towards the inner cavity direction of the box body 1 under the pushing of the telescopic spring 43 until the guide block 42 slides through the bevel section 6, at the moment, the bevel section 6 and the external air passage 6 is also closed with the external air passage 1 is not disturbed, and the dust is not closed, and the dust is not normally enters the electronic box body, and the working part is closed, and the part is not normally, and the part is closed.
Further, as shown in fig. 4, the thickness of the guide block 42 is larger than the caliber of the bevel section 6, and when the telescopic spring 43 is in a natural state, the guide block 42 just seals the opening of the bevel section 6.
Since the guide block 42 closes the bevel section 6 when the temperature in the case 1 drops to the lowest temperature value for safe operation of each component in the power supply case 1, the case 1 is relatively closed, but the case 1 still has heat, and although the heat is insufficient to interfere with the electrical components, after long-term accumulation, the heat cannot be discharged, and the phenomenon of high temperature inside the case 1 is also caused, so as to avoid the phenomenon.
Specifically, as shown in fig. 1-2, a radiating fin 7 is installed on a side wall of one side, far away from the air inlet 2 and the air outlet 3, of the box body 1, two ends of the radiating fin 7 respectively extend out of the outer side of the box body 1 and extend into an inner cavity of the box body 1, and heat exchange between inner and outer gases is realized by using the radiating fin 7, so that the temperature inside the box body 1 is reduced.
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
