[0002] The electrical room is the interface management center for power supply equipment and power-consuming equipment in the power distribution system. It is a branch of the electrical system, mainly used to supply power to users and control the operation of various equipment. The electrical box will generate heat during operation. In order to better operate the electrical box, the electrical room needs to be cooled and cooled under rated conditions. The electrical room usually uses cabinet air conditioners for cooling. However, during the use of cabinet air conditioners, condensation often occurs on precision electronic components such as PLCs due to uneven distribution of cold air flow, which in turn causes corrosion and short circuits in the electronic components. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings. Figure 1 The direction in shall prevail.

[0017] like Figure 1-3As shown, the utility model provides an electrical room for uniform air heat dissipation and temperature reduction, including a room body 1, a buffer room 2 and an electrical room 3 are arranged in the room body 1, an air cooler 4 for air supply and return is installed outside the electrical room 3, a plurality of electrical boxes 5 are evenly arranged in the electrical room 3 along the length direction of the electrical room 3, a foundation 6 is arranged at the bottom of the electrical box 5, the foundation 6 is fixedly connected to the bottom surface of the electrical room 3, two horizontally arranged air ducts are fixedly connected to the top wall of the electrical room 3, the two air ducts are connected to the air cooler 4, and the two air ducts include a return air duct 7 and an air supply duct 8, the return air duct 7 is located at the rear side of the electric box 5, the air supply duct 8 is located at the front side of the electric box 5, and a plurality of air supply ports 9 are evenly arranged at the bottom of the air supply duct 8 and at one side close to the electric box 5; a heat conduction pipe 10 is arranged in the electric box 5, and a vertically arranged return air branch pipe 11 is fixedly connected to the back of the electric box 5, the top end of the return air branch pipe 11 is connected to the return air duct 7, the bottom end of the return air branch pipe 11 extends to the bottom of the electric box, a return air port 13 is arranged at the bottom end of the return air branch pipe 11, and a heat dissipation pipe 12 connected to the heat conduction pipe 10 is arranged in the return air branch pipe 11.

[0018] Specifically, when in use, the air cooler 4 is started, and the air cooler 4 blows out cold air, which is blown evenly into the electrical room 3 from the air supply port 9 through the air supply pipe 8, and then the air in the electrical room 3 flows to the return air port 13, and then returns to the air cooler 4 through the return air port 13, the return air branch pipe 11, and the return air pipe 7 in sequence. Figure 3 As shown, since the air supply port 9 and the return air port 13 are arranged diagonally in the electrical room 3, the cold air forms convection in the electrical room 3, so that the electrical room 3 can be evenly cooled. In addition, since a heat pipe 10 is provided in the electrical box 5, the heat pipe 10 can absorb the heat in the electrical box 5 and transfer it to the heat dissipation pipe 12. The heat dissipation pipe 12 exchanges heat with the air in the return air branch pipe 11, so that the heat is concentrated in the return air branch pipe 11. When the air in the electrical room 3 flows through the return air branch pipe 11, the heat can be taken away, so that the electrical box 5 can be cooled.

[0019] The utility model provides diagonally arranged air supply vents 9 and return air vents 13 in the electrical room 3, so that cold air forms convection in the electrical room 3, thereby making the cold air evenly distributed in the electrical room 3, thereby evenly cooling the electrical room 3 and reducing the occurrence of condensation. Secondly, since the heat conduction pipe 10 is located outside the return air branch pipe 11 and the heat dissipation pipe 12 is located inside the return air branch pipe 11, most of the heat is concentrated in the return air branch pipe 11, thereby reducing the amount of heat radiated to the electrical room 3. At the same time, during the return air process, the heat in the return air branch pipe 11 is discharged from the electrical room 3 through the return air branch pipe 11 and the return air pipe 7 in turn, thereby dissipating heat and cooling the electrical box 5.

[0020] In some embodiments, a control system is provided on the air cooler 4, the control system is electrically connected to the air cooler 4, a temperature sensor 14 is provided in the electrical room 3, the temperature sensor 14 is electrically connected to the control system, the control system, the connection relationship between the control system and the air cooler 4, and the connection relationship between the control system and the temperature sensor 14 are prior art and are not described here. Specifically, when in use, the temperature sensor 14 transmits the temperature signal in the electrical room 3 to the control system. When the temperature is higher than the set value, the control system controls the air cooler 4 to turn on, so that the electrical room 3 can be cooled. When the temperature is lower than the set value, the control system controls the air cooler 4 to turn off, and the cycle is repeated, so that the temperature in the electrical room 3 can be kept within a certain range.

[0021] In some embodiments, the heat dissipation pipe 12 is in a multi-curved shape, so as to increase the heat dissipation speed of the heat dissipation pipe 12 and further increase the heat dissipation speed of the electrical box 5 .

[0022] In some embodiments, a partition 15 is provided between the buffer room 2 and the electrical room 3, a first heat preservation door 16 connecting the buffer room 2 and the electrical room 3 is provided on the partition 15, and a second heat preservation door 17 connecting to the outside is provided on the side wall of the buffer room 2. Specifically, when the technician needs to enter the electrical room 3, he first opens the second heat preservation door 17 to enter the buffer room 2, and then opens the first heat preservation door 16 to enter the electrical room 3. The buffer room 2 reduces the exchange of air between the electrical room 3 and the outside air, thereby reducing the dust and moisture entering the electrical room 3.

[0023] In some embodiments, the outer surface of the room body 1 is coated with a reflective material, which may be an aluminum-based reflective heat-insulating paint, an infrared reflective titanium dioxide pigment, etc. Specifically, by spraying the reflective material on the outer surface of the room body 1, infrared radiation in sunlight can be reflected, thereby reducing the temperature inside the room body 1.

[0024] In some embodiments, a connecting pipe 18 is connected between the air supply pipe 8 and the air cooler 4, and a dustproof net 19 is provided on the connecting pipe 18. Specifically, the dust in the cold air can be filtered by providing the dustproof net 19, thereby reducing the dust from entering the electrical room 3.

[0025] In some embodiments, all openings of the electrical room 3 are equipped with protective rubber rings. Specifically, the protective rubber rings have good sealing performance, thereby reducing the entry of external dust and moisture into the electrical room 3.

[0026] The above embodiments can be combined with each other.

[0027] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the utility model.
