Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1-4, a safe outdoor high voltage distribution cabinet, including high voltage distribution cabinet 1, one side of high voltage distribution cabinet 1 is equipped with cabinet door 2, install electronic component 8 in high voltage distribution cabinet 1, the hollow post 3 of central fixedly connected with of high voltage distribution cabinet 1, the louvre 4 of equipartition is seted up to high voltage distribution cabinet 1's relative both sides, and the relative both sides fixedly connected with equipartition of high voltage distribution cabinet 1 hides canopy I5, hides canopy I5 and is located the top of louvre 4, the fixed intercommunication in bottom both sides of hollow post 3 has opposite return air chamber way 6.
Wherein, hollow column 3 is opened there is the inner chamber, hollow column 3 is the rectangle shape of big end up uniform variation, hollow column 3 is located high voltage distribution cabinet 1's central point and puts, the inner chamber atmospheric pressure that makes hollow column 3 always presents the form big end up, make the hot air that rises in high voltage distribution cabinet 1 and the water collecting cavity 7 after the hollow column 3 of discharging, always upwards discharge hollow column 3, make hollow column 3 upper portion atmospheric pressure continue to reduce, make the cold air in the return air chamber way 6 can follow the bottom of hollow column 3 and upwards move and form the air current, it blocks below water collecting cavity 7 and collects the rainwater to have avoided rain shade II9 when raining simultaneously.
Wherein, the two opposite sides of the inner cavity of the hollow column 3 are respectively and fixedly connected with three water collecting cavities 7 which are uniformly distributed, so that the water collecting cavities 7 can collect rainwater when raining, and the collected rainwater can absorb the radiation heat of the electronic element 8, meanwhile, the water collecting cavities 7 can discharge hot expanding air when being heated, the air at the top of the hollow column 3 is further extruded, the air pressure at the top of the hollow column 3 is reduced again, the flow and the speed of the cold air flow are increased, the volume of the three water collecting cavities 7 from top to bottom is increased by five times from zero, the air pressure of the water collecting cavity 7 at the bottom is always larger than the air pressure of the water collecting cavity 7 at the upper part, and the condition that the cold air flow cannot be formed due to the overlarge air pressure at the upper part is avoided, the opening of the water collecting cavity 7 is inclined upwards, and the electronic element 8 is fixedly connected to the bottom end of the water collecting cavity 7, so that the water collecting cavity 7 can collect rainwater in the rainy days, and the collected rainwater can absorb the radiation heat of the electronic element 8.
Wherein, the equal fixedly connected with rain shade II9 of three equipartition in the opposite both sides of inner chamber of hollow column 3, three rain shade II9 is located the below of three chamber 7 that catchments respectively, rain shade II9 and rain shade I5 all are decurrent circular-arcly, make rain shade II9 can block the rainwater when raining and fall into the damage that causes electronic component 8 in high voltage distribution cabinet 1 from circulation hole 10, make the cold air current form the back simultaneously, receive rain shade II 9's shape influence, most cold air current can both carry out the atmospheric pressure to it and supply in pouring into high voltage distribution cabinet 1 from circulation hole 10, and make more cold air currents cool off electronic component 8.
Wherein, the opposite both sides of inner chamber of hollow post 3 all seted up the circulation hole 10 of three equipartition, and circulation hole 10 is located the below of rainshade II9, makes the hot air that rises in high voltage distribution cabinet 1 can arrange to hollow post from circulation hole 10, makes the cold air current can flow back to high voltage distribution cabinet 1 from circulation hole 10.
Wherein, the one end of return air chamber way 6 runs through high voltage distribution cabinet 1 bottom, makes the air in return air chamber way 6 form the cold air current in air column 3 after, and outside cold air can in time supply it.
The use method (working principle) of the invention is as follows:
firstly, when the electronic element 8 is in a working state without raining, the electronic element 8 radiates heat to enable air in the high-voltage power distribution cabinet 1 to thermally expand, meanwhile, the water collecting cavity 7 which does not store rainwater is also thermally expanded by radiation, most of thermally expanded air in the high-voltage power distribution cabinet 1 is discharged from the heat dissipation holes 4, and a small part of thermally expanded air is discharged from the circulation holes 10 and is influenced by the large upper part and the small lower part of the hollow column 3, so that the hot air discharged from the high-voltage power distribution cabinet 1 and the water collecting cavity 7 is upwards discharged from the upper opening of the hollow column 3, and the air pressure above the hollow column 3 is always lower than the air pressure at the bottom;
then, cold air is introduced into the hollow column 3 from the air return channel 6, moves from bottom to top to form continuous air flow, is influenced by the shape of the rain shade II9, most of the cold air flow backflushs into the high-voltage power distribution cabinet 1 from the circulation hole 10 to supplement the internal air pressure of the high-voltage power distribution cabinet and cool the electronic element 8, and when the internal air is heated by the heat dissipation capacity of the electronic element 8 again, the movement is repeated to finish cooling;
finally, when raining, protected by rain shade I5 and rain shade II 9's circular arc shape, the rainwater will be unable to get into high voltage distribution cabinet 1 in, and when part rainwater fell from hollow column 3 this moment, some rainwater will be collected by water collecting cavity 7, make it to electronic component 8 radiate the heat absorption can.
