Description

Technical Field

[0001] This invention relates to the field of power supply technology, specifically to a special power supply with current monitoring function. Background Technology

[0002] Specialty power supplies are widely used in special environments such as underground coal mines, rail transportation, and spacecraft to provide stable power for various critical equipment. In these applications, real-time current monitoring is crucial for ensuring the safe operation of equipment. However, existing specialty power supply modules are mostly independently designed, with low mechanical integration with the main body, and their shock resistance and protection capabilities are insufficient to meet the stringent requirements of these special environments. Therefore, there is a need for a specialty power supply with a compact structure, convenient installation, and strong mechanical stability, and equipped with current monitoring functionality.

[0003] According to a search, Chinese patent document publication number CN207896852U discloses a power adapter with temperature and current monitoring function. This adapter uses a thermistor switch to monitor the internal temperature of the adapter. When the adapter temperature is too high, a heatsink is activated to dissipate heat. The thermistor switch adjusts its resistance according to the internal temperature change, thereby regulating the heatsink's rotation speed, resulting in more energy-efficient use and preventing adapter damage due to overheating. However, in actual use, this device relies on a cooling fan to cool the entire power supply, which is not only ineffective at cooling the core modules but also has low cooling efficiency and high operating noise. Furthermore, the device lacks a dustproof design, allowing dust to accumulate on the circuit board and components, affecting heat dissipation and potentially causing short circuits, poor contact, and other malfunctions, further reducing power supply stability and lifespan. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a special power supply with current monitoring function, which has the advantages of effective shock absorption, high stability, good heat dissipation, and improved protection capabilities, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a special power supply with current monitoring function, comprising a power supply body, a display screen, control buttons and indicator lights on the front side of the power supply body, a core module inside the power supply body, a small circulating pump fixedly installed inside the power supply body, a first circulating pipe fixedly installed on the right side of the small circulating pump, a water-cooled shell fixedly connected to the end of the first circulating pipe away from the small circulating pump, a heat-conducting metal block fixedly installed inside the water-cooled shell, a second circulating pipe fixedly installed on the outer side of the water-cooled shell, a heat sink fixedly connected to the end of the second circulating pipe away from the water-cooled shell, a third circulating pipe fixedly installed on the right side of the heat sink, and a heat dissipation cover hinged to the rear side of the power supply body.

[0008] Preferably, there are two displays and multiple control buttons and indicator lights.

[0009] Through the above technical solution, the two displays can realize real-time split-screen display of parameters, operation zone control, and intuitive status feedback. This allows operators to simultaneously observe key data such as voltage and current, and to precisely adjust output and switch modes through independent control buttons. In conjunction with indicator lights, they can quickly determine the operating status such as working, fault, and protection, which greatly improves operating efficiency, adjustment accuracy, and equipment operation safety. It is especially suitable for special application scenarios with high requirements for power supply stability and real-time monitoring.

[0010] Preferably, the heat-conducting metal block is connected to the top surface of the core module, and the top surface of the heat-conducting metal block is provided with multiple heat dissipation fins.

[0011] Through the above technical solutions, the heat-conducting metal block can quickly remove the concentrated heat generated by the core module when it is operating at high power through the water cooling circuit, so as to achieve efficient, uniform and stable temperature control, ensure the accuracy of current monitoring and output, and extend the life of the device. In addition, multiple heat dissipation fins can significantly increase the heat exchange area, enhance the heat exchange efficiency between the water cooling medium and the heat-conducting metal block, further improve the heat dissipation capacity, reduce temperature rise and thermal resistance, and allow the power supply to maintain low temperature rise, high reliability and stable operation under long-term high load conditions.

[0012] Preferably, two cooling fans are provided on the rear side of the radiator, and the right end of the third circulation pipe is fixedly connected to the left side of the small circulation pump.

[0013] The above technical solution, through the installation of components such as a small circulating pump, radiator, and third circulating pipe, forms a closed-loop, high-efficiency water-cooling system. This system can quickly and evenly remove the heat generated by the core module during operation, effectively reducing thermal resistance and temperature rise, ensuring current monitoring accuracy and output stability, while improving the reliability and safety of the power supply under long-term high load operation and extending the service life of key components. Simultaneously, the cooling fan can accelerate airflow through forced convection, significantly improving the heat exchange efficiency between the radiator and the external environment, rapidly reducing the temperature of the radiator and internal medium, and enhancing the redundancy and reliability of the cooling system. It should be noted that the working principles of the radiator and other components are existing technologies and will not be elaborated upon here.

[0014] Preferably, the rear side of the heat dissipation cover is provided with multiple heat dissipation holes, and a dust filter is installed on the inner side of the heat dissipation cover.

[0015] Through the above technical solutions, multiple heat dissipation holes can enhance air convection and heat dissipation inside the power supply body, avoiding internal heat accumulation that could affect the accuracy of current monitoring and the stability of components. At the same time, the dust filter can effectively block dust and debris from entering the interior while ensuring ventilation and heat dissipation, preventing short circuits, poor heat dissipation due to dust accumulation, and accelerated aging of components. It balances efficient heat dissipation and dust protection, improving the reliability and service life of special power supplies in complex environments.

[0016] Preferably, the bottom surface of the power supply body has four grooves, and springs and damping rods are installed inside each of the four grooves. The bottom end of the damping rod is fixedly installed with a base, and the end of the spring away from the groove is fixedly connected to the top surface of the base.

[0017] Through the above technical solutions, components such as springs and damping rods can effectively buffer the vibration and impact brought by equipment operation and external environment, reduce the stress deformation and displacement of internal components, especially the current monitoring module, ensure the current sampling accuracy and circuit stability, reduce the risk of resonance, improve the structural vibration resistance, and allow the power supply to work reliably and extend its service life under complex working conditions. It should be noted that the working principle of components such as damping rods is existing technology, so it will not be described in detail here.

[0018] Preferably, the number of bases is four, and the top surface of each of the four bases is provided with multiple mounting holes.

[0019] Through the above technical solutions, the base and mounting holes can provide a stable and precise installation position for the damping linkage and the power supply body, ensuring the reliability of its force direction and buffering effect, and avoiding loosening and displacement that would affect the vibration reduction performance; at the same time, it can further improve assembly efficiency and connection strength, ensure the stable operation of the damping system under vibration conditions, thereby protecting the current monitoring module and core components, and improving the overall reliability of the special power supply.

[0021] 1. This invention forms a closed-loop, high-efficiency water-cooling system by setting up a small circulating pump, radiator, and third circulating pipe. The heat-conducting metal block can quickly remove the concentrated heat generated by the core module when it is operating at high power through the water-cooling loop, achieving efficient, uniform, and stable temperature control, ensuring the accuracy of current monitoring and output, and extending the life of the device. In addition, multiple heat dissipation fins can significantly increase the heat exchange area, enhance the heat exchange efficiency between the water-cooling medium and the heat-conducting metal block, further improve the heat dissipation capacity, reduce temperature rise and thermal resistance, and allow the power supply to maintain low temperature rise, high reliability, and stable operation under long-term high-load conditions.
