They are mainly made of cold-rolled steel cabinets, and are equipped with electronic components such as voltage spike absorbers and voltage transformers. In actual use, there are some functional deficiencies and there is room for improvement. For example, the current overvoltage suppression cabinets mostly rely on passive heat dissipation, which is dissipated through holes on the surface of the cabinet. Some models are equipped with cooling fans, but the fans are turned on continuously, regardless of whether the equipment needs to dissipate heat. They do not have the function of automatic heat dissipation through temperature monitoring.

[0004] Now, a new type of computer room overvoltage suppression cabinet with temperature monitoring function is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the position size of the porous mesh plate corresponds to the position size of the reserved ventilation grooves, and a plurality of groups of holes are evenly arranged inside the porous mesh plate.

[0009] Preferably, the fixing screw passes through the fixing plate and extends into the interior of the front inspection door, and the rear end of the fixing plate and the front end of the front inspection door are tightly fitted.

[0010] Preferably, a temperature sensor is installed at the middle position of the rear end of the main fixing plate, and the air supply fan, the induced draft fan and the temperature sensor are electrically connected.

[0027] See also Figure 1-5 A computer room overvoltage suppression cabinet with a temperature monitoring function also includes a heat dissipation component, which includes a reserved ventilation slot 3, which is arranged inside the front end of a front inspection door 2, and a fixed panel 4 is installed at the front end of the front inspection door 2, and fixing screws 5 are respectively inserted at the four corners of the front end of the fixed panel 4, and a porous mesh panel 6 is fixedly connected inside the fixed panel 4, and a main fixed panel 7 is fixedly connected to the rear end of the porous mesh panel 6, and a blower 8 is installed on one side of the rear end of the main fixed panel 7, and an induced draft fan 9 is installed on the other side of the rear end of the main fixed panel 7, and lithium batteries 10 are respectively fixedly connected to the upper and lower ends of the rear of the main fixed panel 7, and a wire 11 is arranged between one side of the lithium battery 10 and the blower 8 and the induced draft fan 9, and a power connection 13 is arranged at the bottom of the other side of the rear end of the main fixed panel 7;

[0028] The position and size of the porous mesh plate 6 correspond to the position and size of the reserved ventilation groove 3. The porous mesh plate 6 is evenly provided with multiple groups of holes. The fixing screws 5 penetrate the fixed plate surface 4 and extend into the interior of the front inspection door 2. The rear end of the fixed plate surface 4 and the front end of the front inspection door 2 are tightly fitted. A temperature sensor 12 is installed at the middle position of the rear end of the main fixed plate 7. The blower 8, the exhaust fan 9, and the temperature sensor 12 are electrically connected. The blower can be dispatched by temperature monitoring, which can reduce energy consumption while ensuring the heat dissipation capacity;

[0029] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the temperature sensor 12 on the fixed plate 4 senses the temperature rise inside the cold-rolled steel cabinet 1, the induced draft fan 9 draws the hot air inside the cold-rolled steel cabinet 1 outward, and the supply air fan 8 supplies air to the inside of the cold-rolled steel cabinet 1 for cooling, forming an air flow circulation.

[0033] Specifically, Figure 1 and Figure 5 As shown, two workers each grasp the horizontal steel frame 24 at the corresponding position and exert force upward to lift the cabinet. The two sets of horizontal steel frames 24 can match porters of different heights. The silicone gloves 25 can protect the hands of the porters. The longitudinal steel frame 23 serves as a connecting medium between the horizontal steel frame 24 and the cabinet, and is mainly used for force transmission.

[0034] Working principle: When the utility model is in use, firstly, the cold-rolled steel cabinet 1 is used as the main component of the suppression cabinet, and the voltage spike absorber, voltage transformer and other electronic components are installed inside it. When the voltage suppression cabinet suppresses and limits a large-scale surge impact, the temperature of the electronic components inside it will rise significantly.

In the case of no large-scale surge in daily life, the temperature sensor 12 does not detect a high temperature signal, and the fan does not work, which can play a role in energy saving and emission reduction. The power connection 13 provides power for the fan operation and stores part of the power in the lithium battery 10. When the suppression cabinet overheats, the lithium battery 10 supplies power to the fan through the wire 11. The reserved ventilation grooves 3 and the porous mesh plate 6 are convenient for air circulation. The fixed plate 4 and the fixing screws 5 provide physical support for the installation and fixation of the remaining components. The placement box 14 is located inside the equipment. The non-woven bag 18 inside the placement box 14 is filled with desiccant particles 19, which can capture water molecules in the air inside the cabinet to prevent moisture and condensation inside. The partition plate 17 is used to separate the non-woven bag 18. The porous ventilation plate 15 facilitates air circulation. The installation screws 16 facilitate the installation and removal of the placement box 14. When it is necessary to lift the suppression cabinet, two staff members stand on each side of the cabinet, grasp the horizontal steel frame 24 and exert force upward to lift the cabinet. The two sets of horizontal steel frames 24 can match porters of different heights. The silicone gloves 25 can protect the hands of the porters. The longitudinal steel frame 23 serves as a connecting medium between the horizontal steel frame 24 and the cabinet, mainly used for force transmission.
