Description
Technical Field
[0001] The present invention relates to the technical field of automatic temperature control, and particularly to an intelligent temperature-controlled high and low voltage cabinet for a new energy energy storage system. Background Art
[0002] With the rapid development of new energy technologies, the importance of energy storage systems in energy management has become increasingly prominent. One of the core components of the energy storage device in an energy storage system is the high and low voltage cabinet, and its performance is directly related to the operating efficiency and safety of the entire system. However, a large amount of heat is generated during the operation of the energy storage device, especially during high-power output or long-term operation, and temperature control has become a key technical difficulty. If the temperature control is not in place, it may lead to a decline in device performance, a shortened service life, or even safety accidents. Therefore, the development of an intelligent temperature control system that can monitor the temperature changes of the high and low voltage cabinet in real time and perform precise regulation has become an important research direction in the field of new energy energy storage systems.
[0003] Currently, the temperature control technologies for high and low voltage cabinets on the market mainly include passive heat dissipation, air-cooled heat dissipation, and liquid cooling, etc. Passive heat dissipation mainly relies on natural convection and heat conduction, and is suitable for low-power devices, but its heat dissipation efficiency is low; air-cooled heat dissipation improves the heat dissipation effect by installing a fan for forced convection, but it has a large noise and is easily affected by the environment; liquid cooling uses the method of coolant circulation, with a high heat dissipation efficiency, but the system is complex and the maintenance cost is high. In addition, there are also some intelligent temperature control systems combined with temperature sensors in the prior art, but they can often only achieve simple temperature monitoring and alarm functions and cannot perform refined temperature regulation. Passive heat dissipation and air-cooled heat dissipation are difficult to meet the requirements of rapid heat dissipation when facing high-power energy storage systems, resulting in an increase in device temperature and affecting performance; although the existing temperature control systems can monitor the temperature, they lack intelligent regulation capabilities and cannot dynamically adjust the heat dissipation strategy according to the actual temperature changes; the air-cooled heat dissipation system has a large noise during operation and high energy consumption, which does not conform to the design concept of green energy conservation; although the liquid cooling system has a good heat dissipation effect, its structure is complex and the maintenance cost is high, and it is not suitable for large-scale popularization and application.
[0004] Prior Art One, Application Number: CN202010021291.8 discloses a high and low voltage cabinet that can be remotely monitored, including a cabinet body and a shock-absorbing base; the cabinet body is installed on the shock-absorbing base; temperature sensors and humidity sensors are provided on the inner side walls of the cabinet body; an intake fan and an exhaust fan are respectively provided at the diagonal positions on both sides of the cabinet body, and the intake fan is located below the exhaust fan; a controller and a data switch are provided inside the cabinet body, and the temperature sensors, humidity sensors, intake fan, and exhaust fan are respectively electrically connected to the controller, and the controller is electrically connected to the data switch. Although it facilitates the later maintenance work of the high and low voltage cabinet by the backstage personnel and improves the working ability of the high and low voltage cabinet in a harsh environment; however, it only realizes temperature monitoring and heat dissipation through temperature sensors and simple fans, lacks diversified heat dissipation strategies and dynamic regulation capabilities, and cannot meet the rapid heat dissipation requirements of high-power energy storage systems; it can only perform basic temperature monitoring and cannot perform abnormal early warning and potential risk prediction based on historical data and real-time dynamics.
[0005] Prior Art Two, Application Number: CN201810683737.6 discloses a protection device for a high and low voltage cabinet, including a protection cabinet main body, a door body, a dehumidifier, a fire alarm, and a heat dissipation cavity. A heat dissipation cavity is provided at the center position of the bottom end of the protection cabinet main body, a heat dissipation plate is installed at the bottom end inside the heat dissipation cavity, heat dissipation fans are provided inside the heat dissipation cavity on both sides of the heat dissipation plate, a fireproof barrier layer is provided at the bottom end of the protection cabinet main body, folding screw holes are hinged on both side walls of the fireproof barrier layer, a clamping cavity is provided at the center position inside the protection cabinet main body, fixed buckles are provided on the inner side walls of the clamping cavity, lifting buckles are installed at both ends of the fixed buckles, and a temperature sensor is fixed at the center position of the top end of the clamping cavity. Although it not only improves the safety of the protection device during use, improves the convenience of installation of the high and low voltage cabinet, but also extends the service life of the protection device; however, the heat dissipation efficiency is low and the energy consumption is high. Using traditional heat dissipation fans and heat dissipation plates, the heat dissipation efficiency is limited and the energy consumption is high, which does not conform to the design concept of green energy conservation; the system complexity and maintenance cost are high.
[0006] Prior Art Three, Application No.: CN 202210146987.2 discloses a high and low voltage cabinet with a neat wire arrangement function and its usage method, including a cabinet body. A top shell is arranged at the top of the cabinet body, and a limiting mechanism is arranged at the bottom of the top shell. The limiting mechanism includes a discharge pipe, the top of the discharge pipe is communicated with the top shell, and a bracket is welded on the left side of the rear of the top shell. The present invention is used in combination with the cabinet body, the column, the top shell, the feed pipe, the connecting plate, the electric telescopic rod, the blanking mechanism, the bracket, the fixing frame, the motor, the second bracket, the pulling block, the installation base, the through hole, the temperature and smoke integrated sensor, the threaded rod, the guide groove, the guide rod and the extension mechanism. Although it solves the problems that the existing high and low voltage cabinets with a neat wire arrangement function usually do not have the function of automatically detecting fire and extinguishing targeted fires during use, and usually cannot provide backup energy through light energy in outdoor environments, which may cause certain inconveniences to users; however, it can only perform simple detection and alarm, cannot achieve fine temperature control; and fails to make full use of the waste heat generated during the operation of the equipment, resulting in low energy utilization efficiency.
[0007] Currently, Prior Art One, Prior Art Two and Prior Art Three have problems such as low heat dissipation efficiency, insufficient regulation ability, complex system, high energy consumption and low energy utilization efficiency in the prior art.
