Technical Field
[0001] This utility model relates to the field of outdoor control box technology, specifically to an outdoor control box insulation device. Background Technology
[0002] Currently, when outdoor control boxes operate in extreme environments (such as low temperature, high temperature, and humidity), the stability and lifespan of their internal electronic components are easily affected by temperature fluctuations. Traditional insulation devices mostly use fixed insulation layers or single heating / cooling modules, which have the following drawbacks: Low insulation efficiency: The fixed installation method of the insulation material makes it difficult to flexibly adjust the thickness of the insulation layer or replace the material according to actual needs, resulting in insufficient insulation effect under drastic temperature difference environments; Insufficient temperature control capability: Single heating or passive heat dissipation designs cannot dynamically respond to temperature changes, easily leading to excessively high or low temperatures inside the box, affecting equipment operation; Inconvenient maintenance: Traditional structures mostly use bolt fixing or sealant bonding, making disassembly difficult and requiring a lot of time for maintenance; Conflict between ventilation and dust prevention: Existing ventilation designs often allow dust and rainwater to enter due to straight-through openings, affecting the safety of internal components.
[0003] Therefore, we propose an outdoor control box insulation device to solve the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model discloses an outdoor control box insulation device. The technical solution adopted includes a control box frame, with outer grooves evenly formed on the outer side wall and inner grooves evenly formed on the inner side wall. Through holes for installing magnetic plates are evenly formed on the side walls of the control box frame.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6As shown, this utility model discloses an outdoor control box insulation device. The technical solution includes a control box frame 1. The outer side wall of the control box frame 1 has uniformly distributed outer grooves 2, and the inner side wall of the control box frame 1 has uniformly distributed inner grooves 3. The side wall of the control box frame 1 has uniformly distributed through holes for installing magnetic plates 4. An insulation plate 5 is fitted inside the outer groove 2 and magnetically attached to the magnetic plate 4 via a magnetic pad 6. A heating plate 7 is fitted inside the inner groove 3 and magnetically attached to the magnetic plate 4 via a magnetic pad 6. A ventilation assembly 8 is provided on the upper surface of the control box frame 1. The top of the outer side wall of the control box frame 1 has uniformly distributed side ventilation slots 9 that communicate with the ventilation assembly 8. The inner side wall of the control box frame 1 has uniformly distributed through holes for installing magnetic plates 4. A slide rail 10 is provided, which is installed in conjunction with a mounting plate 11 via a sliding track 12 inside the slide rail 10. A bottom air inlet 13 is provided on the lower surface of the control box frame 1, and a dust filter hood 14 is provided at the bottom end of the bottom air inlet 13. An air diffuser hood 15 is provided on the lower surface of the inner cavity of the control box frame 1, which is connected to the bottom air inlet 13. A temperature control fan 16 is provided at the bottom of the air diffuser hood 15. An electric heating wire 17 is fixedly installed on the upper part of the temperature control fan 16 and the middle part of the upper surface of the inner cavity of the control box frame 1. Temperature sensors 18 are provided on the upper part of the temperature control fan 16 and in the middle of the upper surface of the inner cavity of the control box frame 1. The temperature sensors 18, the electric heating wire 17 and the temperature control fan 16 are electrically connected to an external power supply through a microcontroller. A sealing plate 20 is snapped onto the front end of the control box frame 1.
[0024] The electrical components are installed on the surface of the mounting plate 11, and the mounting plate 11 is pushed into the interior of the control box frame 1 through the cooperation of the slide rail 10 and the slide rail 12. The installation of the electrical components is completed. The control box frame 1 is then sealed by the sealing plate 20. The insulation plate 5, which is magnetically attached to the outer groove 2, can be used to insulate the interior of the control box frame 1. The heating plate 7, which is magnetically attached to the inner groove 3, can be used to provide auxiliary heating for the interior of the control box frame 1. The air temperature inside the control box frame 1 is monitored in real time by the temperature sensor 18. The microcontroller then presets the temperature. When the temperature is lower than the preset temperature, the heating wire 17 and the heating plate 7 are activated, and the temperature-controlled fan 16 is activated simultaneously. The air inside the control box frame 1 is heated until the preset temperature is reached. Then, the heating wire 17, heating plate 7, and temperature control fan 16 are turned off. When the temperature is higher than the preset temperature, the temperature control fan 16 is turned on to dissipate heat from the air inside the control box frame 1. Due to the density difference caused by the temperature difference, hot air rises and cold air falls. The hot air inside the control box frame 1 can interact with the outside air in real time through the ventilation component 8 and the side ventilation slot 9, which improves the cooling efficiency. The temperature control fan 16 can also mix the air inside the control box frame 1, quickly mixing hot and cold air to achieve the purpose of heat preservation. At the same time, the air diffuser 15 can enhance the mixing effect of the temperature control fan 16 and improve the temperature control efficiency.
[0025] As a preferred embodiment of this utility model, the ventilation assembly 8 includes an upper air hole 23, a ventilation chamber 24, and a lower air hole 25. The ventilation chamber 24 is located at the top of the control box frame 1. The upper air holes 23 are evenly distributed on the upper surface of the control box frame 1 and are connected to the ventilation chamber 24. The lower air holes 25 are evenly distributed on the upper surface of the inner cavity of the control box frame 1 and are connected to the ventilation chamber 24. The lower air holes 25 and the upper air holes 23 are staggered. The ventilation chamber 24 and the side ventilation slot 9 are connected. The side ventilation slot 9 is an inclined slot, which is opened by the staggered opening of the upper air hole 23 and the lower air hole 25. The upper air hole 23 and the lower air hole 25 are connected to the ventilation chamber 24, which allows the air inside the control box frame 1 to interact with the outside. It can also prevent external dust and debris from falling directly into the inside of the control box frame 1 and contaminating the electrical components. The inclined side ventilation slot 9 can discharge the dust inside the ventilation chamber 24 to the outside of the control box frame 1 with the flow of air.
[0026] As a preferred technical solution of this utility model, the insulation board 5 is formed by bonding an outer layer of heat insulation material and an inner layer of reflective film. The outer layer of heat insulation material is a polyurethane foam board, and the inner layer of reflective film is an aluminum foil. By using the outer layer of heat insulation material, which is a polyurethane foam board, and the inner layer of reflective film, which is an aluminum foil, the outside of the control box frame 1 can be insulated.
[0027] As a preferred technical solution of this utility model, the heating plate 7 is a flexible electric heating film. The flexible electric heating film is electrically connected to an external power supply through a microcontroller. The heating plate 7, which is a flexible electric heating film, can heat the air inside the control box frame 1.
[0028] As a preferred technical solution of this utility model, magnetic grooves 19 are symmetrically provided in the middle of the front side wall of the control box frame 1. Magnetic blocks 21 that cooperate with the magnetic grooves 19 are provided at both ends of the sealing plate 20. Ventilation holes 22 are uniformly provided through the side wall of the sealing plate 20. The sealing plate 20 can be snapped and fixed to the front end of the control box frame 1 by the magnetic blocks 21 that cooperate with the magnetic grooves 19. The ventilation holes 22 that are provided through the side wall of the sealing plate 20 allow the air inside the control box frame 1 to interact with the outside air, thus preventing heat accumulation inside the control box frame 1.
[0029] The working principle of this utility model is as follows: Electrical components are installed on the surface of the mounting plate 11, and the mounting plate 11 is pushed into the control box frame 1 through the cooperation of the slide rail 10 and the slide rail 12, thus completing the installation of electrical components. The control box frame 1 is then sealed by the sealing plate 20. The insulation plate 5, which is magnetically attached to the outer groove 2, provides insulation for the inside of the control box frame 1. The heating plate 7, which is magnetically attached to the inner groove 3, provides auxiliary heating for the inside of the control box frame 1. The temperature sensor 18 monitors the air temperature inside the control box frame 1 in real time, and then the microcontroller presets the temperature. When the temperature is lower than the preset temperature, the heating wire 17 and the heating plate 7 are activated, and the temperature-controlled fan 16 is activated simultaneously to heat the air inside the control box frame 1 until the preset temperature is reached. Then, the heating wire 17, the heating plate 7, and the temperature-controlled fan 16 are turned off. When the temperature is higher than the preset temperature, the temperature-controlled fan 16 is activated to heat the air inside the control box frame 1. The air inside the frame 1 is cooled by the density difference caused by temperature differences, which causes hot air to rise and cold air to fall. The staggered opening of the upper air hole 23 and the lower air hole 25, and their connection with the ventilation chamber 24, allows the air inside the control box frame 1 to interact with the outside. This prevents external dust and debris from falling directly into the control box frame 1 and contaminating the electrical components. The side ventilation slot 9, which is a slanted groove, allows the airflow to expel dust from the ventilation chamber 24 to the outside of the control box frame 1. At the same time, the lower air hole 25, the upper air hole 23, and the ventilation chamber 24 allow the hot air inside the control box frame 1 to interact with the outside air in real time, improving cooling efficiency. The temperature-controlled fan 16 mixes the air inside the control box frame 1, quickly mixing hot and cold air to achieve the purpose of heat preservation. The air diffuser 15 further enhances the mixing effect of the temperature-controlled fan 16, improving temperature control efficiency.
