Description

Technical Field

[0001] This utility model belongs to the field of liquid cooling heat dissipation technology for energy storage cabinets, and in particular relates to a liquid cooling heat dissipation system for energy storage cabinets based on distributed temperature sensors. Background Technology

[0002] Liquid cooling solutions for energy storage are a method to improve the efficiency and stability of energy storage systems through liquid cooling technology. Traditional energy storage systems typically use air cooling, but air cooling has limited heat dissipation efficiency, making the system prone to overheating under high loads, thus affecting system performance and lifespan. Liquid cooling solutions, using liquid as the cooling medium, can better absorb and conduct heat, improving the system's heat dissipation and effectively solving the overheating problem.

[0003] The cooling system consists of coolant, a circulating pump, a cooler, and piping. During operation, the coolant is pumped to the cooler via the circulating pump. The cooler dissipates heat generated by the energy storage system, maintaining a stable operating temperature. After passing through the cooler, the coolant returns to the circulating pump, creating a continuous cooling cycle.

[0004] The working principle of a liquid cooling system is based on the thermal conductivity of liquids. Coolant Circulation: The coolant is the core component of a liquid cooling system. The coolant is typically a liquid with good thermal conductivity, such as water or a special coolant. The coolant enters the equipment through pipes, forming a closed circulation system. Heat Conduction: The coolant comes into contact with heat sources inside the equipment, such as energy storage batteries, and absorbs heat through heat conduction. The high thermal conductivity of the coolant allows it to quickly absorb heat and carry it to other parts of the cooling system. Radiator: The radiator plays a crucial role in a liquid cooling system. Radiators are typically made of copper or aluminum and have large-area fins and heat pipes. The coolant flows through the radiator through the heat pipes, transferring heat to the fins. The large area and high thermal conductivity of the fins allow for efficient heat dissipation. Cooling Device: The cooling device in a liquid cooling system dissipates the absorbed heat into the environment.

[0005] Liquid cooling solutions for energy storage offer several advantages over traditional air cooling methods. First, liquid cooling provides higher heat dissipation efficiency, effectively reducing system operating temperature and improving system efficiency and lifespan. Second, liquid cooling offers better heat conduction performance, reducing hotspots and improving system stability and reliability. Furthermore, liquid cooling reduces system noise and air pollution, enhancing the comfort of the working environment.

[0006] Liquid cooling systems play a crucial role in commercial and industrial energy storage cabinets. However, existing cooling methods suffer from the problem of localized overheating in battery areas, which cannot be detected or cooled in a timely manner. Furthermore, current liquid cooling systems maintain a nearly constant flow rate when temperatures are uneven, failing to achieve effective and balanced cooling based on temperature variations. Utility Model Content

[0007] The purpose of this invention is to provide a liquid cooling heat dissipation system for energy storage cabinets based on distributed temperature sensors, which solves the problem that existing cooling methods have excessively high local temperatures in battery areas, making it impossible to detect and cool them down in a timely manner.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a liquid cooling heat dissipation system for an energy storage cabinet based on a distributed temperature sensor. It includes a cooling unit for cooling the batteries in the energy storage cabinet; a distributed temperature sensor for collecting temperature data on the location of the batteries in the energy storage cabinet; a flow regulation unit for regulating the flow rate of the coolant in the cooling unit; and a control unit for processing the temperature data. The cooling unit, the distributed temperature sensor, and the flow regulation unit are all connected to the control unit.

[0010] Furthermore, the cooling unit includes coolant, a circulating pump, a cooler, and circulating piping.

[0011] Furthermore, the control unit is designated as LC-1000.

[0012] Furthermore, the flow regulating unit includes a solenoid valve or a pump, through which the flow rate of the coolant is regulated.

[0013] Furthermore, the distributed temperature sensor is fixed in the heat source area of ​​the energy storage cabinet battery.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses distributed temperature sensors to detect temperature points, effectively identifying areas of concentrated battery temperature. A cooling device can effectively reduce the temperature of industrial and commercial energy storage cabinets, improving performance and stability.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] This embodiment is a liquid cooling heat dissipation system for an energy storage cabinet based on a distributed temperature sensor, including a cooling unit for cooling the batteries in the energy storage cabinet; the cooling unit includes coolant, a circulating pump, a cooler, and circulating pipelines. The cooling unit adopts an existing cooling device for energy storage batteries, and a flow regulating unit is used to regulate the flow rate of the coolant in the cooling unit; the flow regulating unit includes a solenoid valve or a pump, through which the flow rate of the coolant is regulated.

[0021] By adding a solenoid valve and a pump to the circulation pipeline at each energy storage battery location in the cooling device, the flow rate of the coolant can be adjusted through the solenoid valve, thereby changing the cooling efficiency. This allows the heat-generating points of the energy storage battery to reach a stable temperature environment under the regulation of the cooling circulation pipeline.

[0022] Distributed temperature sensors are fixed in the heat source areas of the energy storage cabinet's batteries to collect temperature data from the battery locations and transmit it to the control unit. During equipment operation, the temperature sensors continuously monitor the temperature of each heat source and transmit this data to the control unit. The control unit analyzes the temperature data; if it detects that the temperature in a certain area exceeds a preset safety threshold, it increases the coolant flow rate in that area to enhance heat dissipation. Conversely, if the temperature is within the safe range, the system can appropriately reduce the flow rate to save energy and improve efficiency.

[0023] The control unit, used for processing temperature data, monitors the equipment's temperature and adjusts the coolant flow and heat dissipation device operation as needed. The cooling unit, distributed temperature sensors, and flow regulation unit are all connected to the control unit. The coolant circulates within the system, carrying away heat, dissipating it through the radiator or heat sink, and then returns to the circulation system.
