Description

Technical Field

[0001] This invention relates to the field of control cabinet technology, and more specifically, to a refrigeration unit control cabinet with temperature control function. Background Technology

[0002] The components of a refrigeration unit include a compressor (or compressor-like subsystem), condenser, expansion valve, evaporator, and control system. The refrigeration compressor is the most important piece of equipment in a refrigeration system, often referred to as the main unit. The process of raising refrigerant vapor from low pressure to high pressure, as well as the continuous flow and transport of the vapor, is accomplished by the operation of the refrigeration compressor. In other words, the functions of the refrigeration compressor are: 1. To draw refrigerant vapor from the evaporator to maintain a certain evaporation pressure within the evaporator; 2. To increase the pressure, compressing the low-pressure, low-temperature refrigerant vapor into high-pressure, high-temperature superheated vapor, creating conditions for condensation at higher temperatures (such as around 35°C in summer); 3. To transport and propel the refrigerant within the system, completing the refrigeration cycle.

[0003] A control cabinet is an assembly of switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel, arranged according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger personnel or surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, and certain electrical parameters can be adjusted. Deviations from normal operating conditions will be indicated or signaled. Control cabinets are commonly used in power generation, distribution, and substations. Refrigeration unit control cabinets are always used in conjunction with dedicated control cabinets.

[0004] The shortcomings of existing technology: Most existing refrigeration unit control cabinets are placed in cold storage. Due to the high humidity in cold storage, the control cabinets often experience short circuits or damage due to moisture, which seriously affects the service life of the control cabinets. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a refrigeration unit control cabinet with temperature control function. An air pump is used to achieve internal air circulation within the control cabinet, and heat generated by electrical equipment removes moisture. This dehumidification method is energy-efficient and avoids moisture affecting the electrical components within the control cabinet, thus protecting the electrical components and effectively preventing short circuits or damage, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a refrigeration unit control cabinet with temperature control function, comprising a control cabinet body, a fixed frame connected to the top of the control cabinet body, a movable tube rotatably connected to one side of the top of the fixed frame, an air pump fixedly installed on the top of the control cabinet body, an exhaust pipe connected to the top of the air pump, the movable tube being rotatably and sealingly connected to the exhaust pipe, an air suction pipe connected to the bottom of the air pump, the air suction pipe communicating with the control cabinet body, a temperature and humidity sensor fixedly installed on one side of the bottom of the inner cavity of the control cabinet body, a controller fixedly installed on the bottom of the inner cavity of the control cabinet body, and several first heat dissipation slots equidistantly distributed from top to bottom fixedly installed on both sides of the control cabinet body, the output end of the temperature and humidity sensor being electrically connected to the input end of the controller, and the output end of the controller being electrically connected to the input end of the air pump.

[0007] The beneficial effects of adopting the above-mentioned further solution are as follows: By setting a certain temperature range for the temperature and humidity sensor, when the temperature inside the control cabinet is within the set temperature range, the temperature and humidity sensor transmits a physical signal to the controller. The controller then controls the air pump to operate, and the air pump discharges the hot air from inside the control cabinet, thereby cooling the inside of the control cabinet. Through the controller, air pump, and temperature and humidity sensor, the temperature inside the control cabinet is controlled, preventing damage to the electrical components caused by excessively high internal temperatures.

[0008] In a preferred embodiment, a dual-head motor is fixedly installed on the top of the control cabinet. A first transmission mechanism is connected between the output shaft of the dual-head motor and the movable tube. A fixed tube is connected through the top of the control cabinet near the controller. A U-shaped frame is installed on the top of the inner cavity of the control cabinet. Both sides of the top of the control cabinet are sealed and rotatably connected with lead screws. The lead screws on both sides are threadedly connected to the U-shaped frame. A second transmission mechanism is connected between the output shaft of the dual-head motor and the lead screws on both sides. Several second heat dissipation slots are fixedly installed on both sides of the U-shaped frame, equidistantly distributed from top to bottom.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: The temperature and humidity sensor is set to a certain humidity range. When the humidity inside the control cabinet is within the set range, the dual-head motor rotates forward, driving the movable tube to rotate at a certain angle, making the movable tube connect with the fixed tube. Simultaneously, the dual-head motor drives the U-shaped frame to move upward a certain distance, causing the first heat dissipation slots on both sides to intersect with the second heat dissipation slots on both sides. The U-shaped frame blocks the first heat dissipation slots. At this time, the air pump circulates the air inside the control cabinet, and the heat generated by the electrical equipment removes the moisture. This dehumidification method is energy-efficient and avoids moisture affecting the electrical components inside the control cabinet, thus protecting the electrical components and effectively preventing short circuits or damage.

[0010] In a preferred embodiment, the first transmission mechanism includes a driven gear connected to the outside of the movable tube and a driving gear connected to the top of the output shaft of the dual-head motor, wherein the driving gear meshes with the driven gear.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the setting of the first transmission mechanism enables the dual-head motor to drive the movable tube to rotate, avoiding the need to set up a separate drive device to drive the movable tube to rotate, thus saving resources and energy.

[0012] In a preferred embodiment, the second transmission mechanism includes a drive sprocket connected to the bottom of the output shaft of the dual-head motor and driven sprockets connected to the bottom of the lead screws on both sides, with a chain connecting the drive sprocket and the driven sprockets on both sides.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the setting of the first transmission mechanism enables the U-shaped frame to move up and down driven by a dual-head motor, avoiding the need to set up a separate drive device to drive the U-shaped frame up and down, thus saving resources and energy.

[0014] In a preferred embodiment, the output of the controller is electrically connected to the input of the dual-head motor.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the controller can be programmed to intelligently control the dual-head motor.

[0016] In a preferred embodiment, a fan is fixedly installed on the bottom side of the control cabinet cavity away from the controller. An air inlet pipe is connected through the bottom of the control cabinet. A first grid is connected to the bottom inner side of the air inlet pipe. A desiccant is placed inside the cavity formed by the air inlet pipe and the first grid. A sealing plate is connected to the top of the air inlet pipe. A second grid is fixedly installed in the middle of the sealing plate.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: During dehumidification, the air pump can no longer dissipate heat. At this time, the fan continuously draws out the hot air inside the control cabinet, and the outside air continuously enters the control cabinet through the air inlet pipe. The incoming air is dehumidified by the desiccant, thereby effectively preventing a large amount of moisture from entering the control cabinet. When the moisture inside the control cabinet drops to the set range, the movable pipe and U-shaped frame return to their initial positions, and the fan is turned off. The fan is designed to facilitate heat dissipation during the dehumidification process, avoiding excessive temperature inside the control cabinet during dehumidification that could damage electrical components.

[0018] In a preferred embodiment, the output of the controller is electrically connected to the input of the fan.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the controller can be programmed to intelligently control the wind turbine.

[0020] In a preferred embodiment, a mounting plate is connected to the bottom of the inner cavity of the control cabinet, and a plurality of equally spaced through slots are provided on the top of the mounting plate.

[0021] The advantages of adopting the above-mentioned further solutions are: the installation of the mounting plate facilitates the installation of electrical equipment, and the through groove facilitates the connection between the top and bottom of the control cabinet.

[0022] The technical effects and advantages of this invention are as follows:

[0023] 1. Set a certain temperature range for the temperature and humidity sensor. When the temperature inside the control cabinet is within the set temperature range, the temperature and humidity sensor transmits a physical signal to the controller. The controller then controls the air pump to run. When the air pump runs, it discharges the hot air inside the control cabinet, thereby cooling the inside of the control cabinet. The controller, air pump, and temperature and humidity sensor are used to control the temperature inside the control cabinet, preventing damage to the electrical components caused by high internal temperature.

[0024] 2. Set the temperature and humidity sensor to a certain humidity range. When the humidity inside the control cabinet is within the set temperature range, the dual-head motor rotates forward to drive the movable tube to rotate a certain angle, so that the movable tube is connected to the fixed tube. At the same time, the dual-head motor drives the U-shaped frame to move upward a certain distance, so that the first heat dissipation slots on both sides intersect with the second heat dissipation slots on both sides. The U-shaped frame blocks the first heat dissipation slots. At this time, the air pump realizes the internal air circulation inside the control cabinet. The heat generated by the electrical equipment removes the moisture. The dehumidification is relatively energy-saving and avoids the moisture from affecting the electrical components inside the control cabinet, thus protecting the electrical components and effectively preventing short circuits or damage to the electrical components.

[0025] 3. During dehumidification, the air pump can no longer dissipate heat. At this time, the fan continuously draws out the hot air from inside the control cabinet, and outside air continuously enters the control cabinet through the air inlet pipe. The desiccant dehumidifies the incoming air, thereby effectively preventing a large amount of moisture from entering the control cabinet. When the moisture inside the control cabinet drops to the set range, the movable pipe and U-shaped bracket return to their initial positions, and the fan is turned off. The fan is designed to facilitate heat dissipation during the dehumidification process, avoiding excessive temperature inside the control cabinet that could damage electrical components.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1-6As shown, a refrigeration unit control cabinet with temperature control function includes a control cabinet body 1, a fixed frame 2 connected to the top of the control cabinet body 1, a movable pipe 3 rotatably connected to one side of the top of the fixed frame 2, an air pump 4 fixedly installed on the top of the control cabinet body 1, an exhaust pipe 5 connected to the top of the air pump 4, the movable pipe 3 and the exhaust pipe 5 being rotatably sealed together, an air suction pipe 6 connected to the bottom of the air pump 4, the air suction pipe 6 communicating with the control cabinet body 1, a temperature and humidity sensor 7 fixedly installed on one side of the bottom of the inner cavity of the control cabinet body 1, a controller 8 fixedly installed on the bottom of the inner cavity of the control cabinet body 1, and several first heat dissipation slots 24 evenly distributed from top to bottom fixedly installed on both sides of the control cabinet body 1, the output end of the temperature and humidity sensor 7 being electrically connected to the input end of the controller 8, and the output end of the controller 8 being electrically connected to the input end of the air pump 4.

[0036] The temperature and humidity sensor 7 is set to a certain temperature range. When the electrical components inside the control cabinet 1 are in use, they will generate a lot of heat. When the temperature inside the control cabinet 1 is within the set temperature range, the temperature and humidity sensor 7 will transmit a physical signal to the controller 8. The controller 8 will control the air pump 4 to run. When the air pump 4 is running, it will draw in the hot air inside the control cabinet 1 through the intake pipe 6 and discharge it through the exhaust pipe 5 and the movable pipe 3, thereby cooling the inside of the control cabinet 1. When the temperature inside the control cabinet 1 is lower than the set stable range, the controller 8 will control the air pump 4 to stop. The controller 8, the air pump 4 and the temperature and humidity sensor 7 are used to control the temperature inside the control cabinet 1, so as to avoid damage to the electrical components inside the control cabinet 1 due to the high temperature.

[0037] like Figure 1-6As shown, a dual-head motor 9 is fixedly installed on the top of the control cabinet 1. A first transmission mechanism 10 is connected between the output shaft of the dual-head motor 9 and the movable tube 3. A fixed tube 11 is connected through the top of the control cabinet 1 near the controller 8. A U-shaped frame 12 is installed on the top of the inner cavity of the control cabinet 1. Screws 13 are rotatably connected to both sides of the top of the control cabinet 1. The screws 13 on both sides are threadedly connected to the U-shaped frame 12. A second transmission mechanism 14 is connected between the output shaft of the dual-head motor 9 and the screws 13 on both sides. Several transmission mechanisms are fixedly installed on both sides of the U-shaped frame 12. The first transmission mechanism 10 includes a driven gear 101 connected to the outside of the movable tube 3 and a driving gear 102 connected to the top of the output shaft of the dual-head motor 9. The driving gear 102 meshes with the driven gear 101. The second transmission mechanism 14 includes a driving sprocket 141 connected to the bottom of the output shaft of the dual-head motor 9 and a driven sprocket 142 connected to the bottom of the lead screws 13 on both sides. A chain 143 connects the driving sprocket 141 and the driven sprockets 142 on both sides. The output end of the controller 8 is electrically connected to the input end of the dual-head motor 9.

[0038] The temperature and humidity sensor 7 is set to a certain humidity range. When the humidity inside the control cabinet 1 is within the set range, the temperature and humidity sensor 7 transmits a physical signal to the controller 8. At this time, the controller 8 controls the dual-head motor 9 to rotate forward by a certain angle, such as... Figure 3 As shown, when the dual-head motor 9 rotates forward, it drives the movable tube 3 to rotate at a certain angle through the first transmission mechanism 10, so that the movable tube 3 is connected to the fixed tube 11. At the same time, when the dual-head motor 9 rotates forward, it drives the lead screws 13 on both sides to rotate simultaneously through the second transmission mechanism 14. Since the lead screws 13 on both sides are threadedly connected to the U-shaped frame 12, when the lead screws 13 on both sides rotate, they drive the U-shaped frame 12 to move upward a certain distance. At this time, the first heat dissipation grooves 24 on both sides and the second heat dissipation grooves 15 on both sides are intersected. The U-shaped frame 12 blocks the first heat dissipation grooves 24. At this time, the air pump 4 draws air from the control cabinet 1 and discharges the drawn air back into the control cabinet 1. The air pump 4 realizes the internal air circulation in the control cabinet 1. The heat generated by the electrical equipment removes the moisture. The dehumidification is relatively energy-saving and avoids the moisture from affecting the electrical components in the control cabinet 1. It protects the electrical components and effectively prevents the electrical components from short-circuiting or being damaged.

[0039] like Figure 6-7As shown, a fan 16 is fixedly installed on the bottom side of the control cabinet 1 away from the controller 8. An air inlet pipe 17 is connected through the bottom of the control cabinet 1. A first grid 18 is connected to the bottom inside the air inlet pipe 17. A desiccant 19 is placed inside the cavity formed by the air inlet pipe 17 and the first grid 18. A sealing plate 20 is connected to the top of the air inlet pipe 17. A second grid 21 is fixedly installed in the middle of the sealing plate 20. The output end of the controller 8 is electrically connected to the input end of the fan 16.

[0040] During dehumidification, the temperature inside the control cabinet 1 continuously rises due to the heat generated by the electrical components, and the air pump 4 can no longer dissipate heat. At this time, the controller 8 controls the fan 16 to operate, and the fan 16 continuously draws out the hot air from the control cabinet 1. Outside air continuously enters the control cabinet 1 through the air inlet pipe 17, and the desiccant 19 dehumidifies the incoming air, thereby effectively preventing a large amount of moisture from entering the control cabinet. When the humidity inside the control cabinet 1 drops to a set range, such as... Figure 2 As shown, the controller 8 controls the movable tube 3 and the U-shaped frame 12 to return to their initial positions. At the same time, the controller 8 controls the fan 16 to turn off. The fan 16 is designed to facilitate heat dissipation during the dehumidification process, preventing the temperature inside the control cabinet 1 from becoming too high and damaging the electrical components.
