Description

Technical Field

[0001] This application relates to the field of energy storage temperature control, and particularly to a liquid cooling device with a fire extinguishing chamber. Background Art

[0002] Compared with traditional air cooling technology, liquid cooling technology has higher cooling efficiency and lower noise level, so it has been widely used in high-density and high-power devices. Generally, a liquid cooling system removes the heat generated by the device through liquid circulation, and then dissipates the heat to the environment through a heat exchanger.

[0003] Although the existing liquid cooling technology performs well in some aspects, there are still some deficiencies in practical applications. First, traditional liquid cooling systems perform poorly in the face of sudden fires. Since the liquid cooling system mainly focuses on the thermal management of the device and fails to effectively integrate the fire protection function, when a fire occurs in the device under high-temperature environment or electrical fault, the liquid cooling system cannot control the fire in time, but may instead contribute to the spread of the fire due to the liquid medium in the system. Second, the structural design of the existing liquid cooling system is relatively complex, and the maintenance and management costs are relatively high. Components such as pipes, pumps, and heat exchangers in the liquid cooling system need to be regularly inspected and replaced. Once a part of the system fails, it may lead to the failure of the entire system. In addition, the installation and commissioning process of the traditional liquid cooling system is cumbersome and occupies a large space, which is a challenge for some equipment installation environments with limited space. The complex installation process and high maintenance costs increase the usage cost and limit the popularization and application of liquid cooling technology in a wider range of fields.

[0004] To solve these problems, it is of great significance and value to develop a liquid cooling device with a fire extinguishing chamber. Summary of the Utility Model

[0005] The purpose of this application is to at least overcome one deficiency existing in the prior art, and provide a liquid cooling device with a fire extinguishing chamber. This liquid cooling device combines effective liquid cooling technology with a fire extinguishing function, which can not only dissipate heat efficiently, but also quickly extinguish fires in case of emergencies, ensuring the safe operation of energy storage devices and power batteries.

[0006] To achieve the above-mentioned objectives, the present application discloses a liquid cooling device with a fire extinguishing chamber, comprising a heat exchange plate and a controller, wherein the heat exchange plate is stacked from top to bottom with a first liquid storage layer for storing a fire-based fire extinguishing agent, a second liquid storage layer for storing a return cooling liquid, an insulation layer, and a heat exchange fire extinguishing layer; the heat exchange fire extinguishing layer is provided with a plurality of heat exchange flow channels and at least one fire extinguishing flow channel, and correspondingly, the bottom surface of the heat exchange fire extinguishing layer is provided with at least one nozzle connected to the fire extinguishing flow channel; the fire extinguishing flow channel is connected to the first liquid storage layer through a fire extinguishing pipe with a control valve, and the liquid outlet end of the heat exchange flow channel is connected to the second liquid storage layer through a pipeline; the second liquid storage layer has a return liquid port, which is connected to an external circulating liquid cooling device; the heat exchange fire extinguishing layer is provided with at least one temperature sensor; the control valve and the temperature sensor are connected to the controller.

[0007] In some embodiments, the first liquid storage layer has a liquid injection port with a cover, and a water-based fire extinguishing agent can be injected into the first liquid storage layer.

[0008] In some embodiments, the reflux port is provided with a filter.

[0009] In some embodiments, the fire extinguishing pipe is connected to a liquid pump. When in operation, the liquid pump injects the water-based fire extinguishing agent in the first liquid storage layer into the fire extinguishing flow channel under high pressure.

[0010] In some embodiments, the thermal insulation layer comprises a thermal insulation foam board.

[0011] Compared with the existing technology, this liquid cooling device combines the dual functions of cooling and fire extinguishing. Through the heat exchange flow channels and fire extinguishing flow channels in the heat exchange and fire extinguishing layer, it achieves efficient heat exchange and rapid spraying of fire extinguishing agent, providing comprehensive high temperature and fire protection.

[0020] As Figure 1 、 2 shown, this embodiment provides a liquid cooling device with a fire extinguishing chamber. The device includes a heat exchange plate 1, a controller 2, and several functional layers. The overall structure is compact and reasonably designed, and can effectively achieve the dual functions of cooling and fire extinguishing. First, the heat exchange plate 1 of the liquid cooling device is stacked from top to bottom with a first liquid storage layer 3 for storing fire-based fire extinguishing agent, a second liquid storage layer 4 for storing the reflux cooling liquid, a heat insulation layer 5, and a heat exchange and fire extinguishing layer 6. Each functional layer forms an integral device through close stacking and mutual connection, ensuring the effective cooperation and coordinated operation between the layers.

[0021] The first liquid storage layer 3 is primarily used to store fire-based extinguishing agents and is made of highly sealed materials, such as stainless steel or high-density polyethylene, to ensure that the extinguishing agent does not leak. The first liquid storage layer 3 is equipped with a covered liquid inlet for convenient injection of extinguishing agent and a liquid level sensor for real-time monitoring of the extinguishing agent inventory. In actual use, when the system detects a fire, the controller 2 controls the liquid pump 9 to start, injecting the extinguishing agent in the first liquid storage layer 3 into the fire extinguishing channel 8 at high pressure through the fire extinguishing pipe, rapidly spraying and extinguishing the fire. The second liquid storage layer 4 is used to store the returned coolant and is made of corrosion-resistant materials, such as polypropylene or galvanized steel, to ensure long-term and stable storage of the coolant. The second liquid storage layer 4 is equipped with a return port that is connected to an external circulating liquid cooling device and has a built-in filter to prevent impurities from entering the system, ensuring the purity of the coolant. After absorbing heat in the heat exchange channel 7, the coolant flows back to the second liquid storage layer 4 and re-enters the cooling cycle through the circulating liquid cooling device.

[0022] The insulation layer 5 is located between the first and second liquid storage layers 3 and 4. It is made of a high-efficiency thermal insulation material with an insulating foam board. Its thickness is designed to a reasonable value to effectively block heat transfer and maintain a stable temperature in each liquid storage layer. The insulation layer 5 is embedded in the upper and lower layers, tightly fitting them to ensure effective insulation.

[0023] The heat exchange and fire extinguishing layer 6 is the core functional layer of the device, and is equipped with several heat exchange channels 7 and at least one fire extinguishing channel 8. The heat exchange channel 7 is designed to be spiral or wavy to improve heat exchange efficiency and is made of materials with excellent thermal conductivity, such as copper or aluminum alloy. During the heat exchange process, the coolant passes through the heat exchange channel 7, absorbing heat from the surrounding environment to achieve efficient cooling. The fire extinguishing channel 8 is connected to the first liquid storage layer 3 through a fire extinguishing pipe with a control valve, and at least one nozzle is opened on the bottom surface for high-pressure injection of fire extinguishing agent. The number and distribution of nozzles are designed according to actual needs to ensure that the fire extinguishing agent is evenly distributed and the fire source is quickly extinguished. In addition, the heat exchange and fire extinguishing layer 6 is also equipped with at least one temperature sensor for real-time monitoring of the temperature within the layer and transmitting the data to the controller 2. Based on the data from the temperature sensor, the controller 2 controls the operating status of the liquid pump 9 and the control valve to ensure that the system operates within the optimal temperature range to prevent overheating and fire.

[0024] During actual use, if an abnormally high temperature is detected inside the device or in the surrounding environment, the temperature sensor transmits a signal to controller 2, which immediately activates liquid pump 9, injecting the fire extinguishing agent from the first liquid reservoir 3 into the fire extinguishing channel 8 through the fire extinguishing pipe at high pressure. The agent is then sprayed through the nozzle, quickly extinguishing the fire. Simultaneously, coolant circulates through the heat exchange channel 7, removing excess heat and lowering the device temperature.

[0025] The specific operation steps are as follows. First, inject the fire-based fire extinguishing agent into the liquid injection port of the first liquid storage layer 3 and ensure it is sealed with a lid. Then, inject the coolant into the second liquid storage layer 4 and ensure that the filter screen at the liquid return port is clean and unblocked. Next, start the external circulating liquid cooling device to ensure that the coolant circulates in the heat exchange flow channel 7. Start the controller 2 to monitor the temperature inside the heat exchange and fire extinguishing layer 6. The temperature sensor transmits the temperature data to the controller 2 in real time. When the temperature sensor detects an abnormal increase in temperature, the controller 2 starts the liquid pump 9, and the liquid pump 9 injects the fire extinguishing agent in the first liquid storage layer 3 into the fire extinguishing flow channel 8 under high pressure and sprays the fire extinguishing agent through the nozzle. At the same time, the coolant circulates through the heat exchange flow channel 7 to take away the excess heat and reduce the equipment temperature.

[0026] In summary, the liquid cooling device with a fire extinguishing chamber provided in this embodiment realizes the functions of efficient cooling and fire extinguishing through reasonable structural design and effective cooperation of each component, is applicable to various industrial and fire protection scenarios, and has high practical value.

[0027] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Therefore, all changes and modifications are included within the protection scope of the present disclosure defined by the claims.
