Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a controller with voltage protection. Background Art

[0002] Solar controllers are important devices used to manage and control the conversion and storage of electrical energy in solar power generation systems. They play a key role between solar panels and batteries, ensuring efficient and stable operation of the system. To ensure the safety and stable operation of the controller equipment, the input voltage is usually monitored. When the voltage exceeds the set range, protective measures are quickly taken to prevent overvoltage or undervoltage from damaging the equipment.

[0003] However, the solar controller in the existing technology will cause abnormal changes in the internal temperature of the controller when the voltage is abnormal. When high temperature heat problems occur, it will affect the controller motherboard and power connector. Long-term accumulation may lead to device performance degradation and frequent failures. Therefore, there is room for improvement in improving the heat dissipation of the controller device when the voltage is too high or too low. Utility Model Content

[0005] To this end, one purpose of the present invention is to propose a controller with voltage protection, which can activate power-off protection and cooling fans when abnormal voltage is detected, and use several air inlet pipes to exhaust and dissipate heat for the controller mainboard and the inside of the shell to quickly cool down.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a controller with voltage protection, comprising a shell, a base plate installed at the bottom of the shell, a controller mainboard installed on the base plate, a power connector installed on one side of the shell, ventilation boxes provided on both sides of the inner wall of the shell, a plurality of equally spaced air inlet pipes embedded on adjacent sides of the two ventilation boxes, the air inlets of the air inlet pipes are located at the top of the controller mainboard, cooling fans are embedded on the front surfaces of the two ventilation boxes, the exhaust ends of the cooling fans are located outside the shell, a battery is provided inside the shell, the battery, the power connector and the cooling fan are all electrically connected to the controller mainboard through wires, a voltage detection probe is installed on the power connector, and the voltage detection probe is electrically connected to the controller mainboard.

[0007] Preferably, an LED lamp bead is installed on the top of the housing, and the LED lamp bead is electrically connected to the controller mainboard through a wire.

[0008] Preferably, a cover plate is fixedly connected to one side of the shell, and the battery is located inside the cover plate.

[0009] Preferably, a connecting plate is fixedly connected to the rear surface of the ventilation box, and the connecting plate is threadedly connected to the inner wall of the shell through bolts.

[0010] Preferably, a temperature sensor is installed on the ventilation box, and the temperature sensor is electrically connected to the controller mainboard.

[0011] Preferably, the air inlet pipe is a copper pipe.

[0012] Compared with the existing technology, the beneficial effects of the present invention are: when the present invention is used, the voltage detection probe monitors the input voltage in real time and transmits data. If abnormal voltage is detected, the controller mainboard starts the power-off protection and the cooling fan. The cooling fan is powered by the battery and uses a number of air inlet pipes to exhaust and dissipate heat for the controller mainboard and the inside of the shell, quickly cooling down, ensuring that the equipment temperature is within a safe range, and improving the stability and life of the controller.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 2 An embodiment of the present utility model provides a controller with voltage protection, including: a housing 1 and a base plate 2.

[0020] In this embodiment, Figures 1-4 As shown, a base plate 2 is installed at the bottom of the shell 1, and a controller main board 7 is installed on the base plate 2. A power connector 13 is installed on one side of the shell 1. Ventilation boxes 8 are provided on the inner walls on both sides of the shell 1. The adjacent sides of the two ventilation boxes 8 are embedded with several equidistantly arranged air inlet pipes 9, wherein the air inlet pipes 9 are copper pipes, and the air inlet of the air inlet pipes 9 is located at the top of the controller main board 7. The front surfaces of the two ventilation boxes 8 are embedded with cooling fans 4, and the exhaust end of the cooling fan 4 is located outside the shell 1.

[0021] Furthermore, a battery 6 is provided inside the housing 1. The battery 6, the power connector 13 and the cooling fan 4 are all electrically connected to the controller mainboard 7 through wires. A voltage detection probe 12 is installed on the power connector 13, and the voltage detection probe 12 is electrically connected to the controller mainboard 7.

[0022] During use, when the controller is connected to the power supply through the power connector 13, the power is transmitted to the controller mainboard 7 through the wire, and the voltage detection probe 12 monitors the input voltage in real time and transmits the data to the controller mainboard 7. If an abnormal voltage is detected, the controller mainboard 7 will activate the power-off protection mechanism and simultaneously start the cooling fan 4, and use several air inlet pipes 9 to exhaust and dissipate heat to the controller mainboard 7 and the inside of the shell 1, and discharge the hot air out of the shell 1.

[0023] It should be noted that, referring to Figure 2 When the controller mainboard 7 starts the power-off protection mechanism, the input of the external power supply is cut off, and the battery 6 is used to provide power for the operation of the cooling fan 4. Among them, a cover plate 3 is fixedly connected to one side of the shell 1, and the battery 6 is located inside the cover plate 3. The cover plate 3 can cover and protect the battery 6.

[0024] Among them, such as Figure 2 and Figure 3 As shown, a temperature sensor 10 is installed on the ventilation box 8 , and the temperature sensor 10 is electrically connected to the controller mainboard 7 . The temperature sensor 10 can monitor the internal temperature of the housing 1 in real time.

[0025] like Figure 1 As shown, an LED lamp bead 5 is installed on the top of the housing 1. The LED lamp bead 5 is electrically connected to the controller mainboard 7 through a wire. The LED lamp bead 5 can display the circuit connection status when the controller is operating normally.

[0026] Specifically, a connecting plate 11 is fixedly connected to the rear surface of the ventilation box 8 , and the connecting plate 11 is threadedly connected to the inner wall of the housing 1 through bolts.

[0027] According to the above technical solution, the working steps of this solution are summarized and sorted out: when the controller provided by the present invention is connected to the power supply through the power connector 13, the power is transmitted to the controller main board 7 through the wire, and the voltage detection probe 12 monitors the input voltage in real time and transmits the data to the controller main board 7. If an abnormal voltage is detected, the controller main board 7 will start the power-off protection mechanism and start the cooling fan 4 at the same time, and use several air inlet pipes 9 to exhaust and dissipate heat to the controller main board 7 and the inside of the shell 1, and discharge the hot air out of the shell 1, thereby accelerating the cooling of the high temperature phenomenon of the controller main board 7 or the power connector 13 caused by the abnormal voltage, ensuring that the temperature of the equipment is maintained within a safe range when the voltage is abnormal, thereby improving the stability and life of the controller.
