DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Energy storage battery systems are an important part of modern power systems and smart grids, and are also an important link in achieving the grid connection, consumption and efficient application of distributed power generation of renewable energy. Compared with other energy storage methods, electrochemical energy storage has the advantages of short response time, high energy density and small site restrictions. For electrochemical energy storage, the development and use of lithium batteries are the focus of attention. Among them, the cooling and heating of lithium batteries are the core issues, which are related to the future development of the energy storage industry.

[0027] At present, the thermal management methods of energy storage devices or systems with heat dissipation requirements are roughly divided into air cooling and liquid cooling, and liquid cooling is currently widely used in equipment or systems of various sizes. In equipment or systems with heat dissipation requirements, if there are devices with different operating temperature requirements, in order to ensure that the devices with different operating temperature requirements can operate in the normal operating temperature range respectively, a set of liquid cooling units can be independently set up for the main devices. Usually, in an energy storage system, battery modules and other modules with high heat generation will be equipped with liquid cooling units separately, and a separate control system will be used to control the liquid cooling units of each module separately to achieve the best heat dissipation and cooling effect.

[0028] When multiple sets of liquid cooling modules are required for the same energy storage system, the space occupied by the entire system will increase, thereby reducing the space utilization rate. At the same time, the use of multiple sets of liquid cooling modules and corresponding control systems increases the cost of use, and the overall structure is therefore more complicated, which leads to higher technical difficulty during disassembly and maintenance. In order to solve the above problems, this embodiment is provided.

[0029] Reference Figures 1 to 6 This is the embodiment 1, wherein Figure 1 is a schematic cross-sectional view of the overall structure of this embodiment 1, Figure 2 is a schematic diagram of the front view of the heat dissipation module structure of this embodiment 1, Figure 6 This is a schematic diagram of the main structure of the dehumidification module of the present embodiment 1. The present embodiment 1 is a split liquid cooling unit, including a heat dissipation module, which is a block structure. The bottom of the heat dissipation module is a heat dissipation shell, a heat dissipation cover is installed outside the heat dissipation shell, and a plurality of heat dissipation fans are installed in the heat dissipation cover. The heat dissipation shell is fixed to one side of the heat dissipation plate, and the other side of the heat dissipation plate is fixed to the liquid cooling plate; the dehumidification module includes an assembly plate, a plurality of air guide nets are provided on one side of the assembly plate, and an air guide cover is fixed to the outer periphery of the air guide net, and a condenser is installed on the other side of the assembly plate.

[0030] This split liquid cooling unit is designed to provide efficient heat dissipation and dehumidification. The heat dissipation module adopts a block structure with a heat dissipation shell at the bottom. This design helps to increase the heat dissipation area and improve the heat dissipation efficiency. The heat dissipation cover installed outside the heat dissipation shell and the heat dissipation fan inside can form effective air convection to quickly take away the heat and ensure stable operation of the equipment.

[0031] The heat sink is an important part of the heat dissipation module. It is fixed with the liquid cooling plate and takes away the heat from the equipment through the liquid cooling circulation system. This design not only ensures the heat dissipation effect, but also improves the reliability and stability of the equipment.

[0032] The dehumidification module guides and distributes the air through the air guide net and air guide cover on the assembly board. The design of the air guide net can increase the contact area between the air and the condenser, and improve the dehumidification efficiency. The condenser installed on the other side of the assembly board uses the condensation principle to condense the moisture in the air into liquid, thereby achieving the purpose of dehumidification.

[0033] The entire split liquid cooling unit has a compact structure and comprehensive functions. It can not only meet the heat dissipation needs of the equipment, but also effectively remove moisture from the air, ensuring that the equipment can operate normally even in harsh environments. This design not only increases the service life of the equipment, but also reduces the maintenance cost of the equipment.

[0034] Reference Figure 3 This is a top view schematic diagram of the heat dissipation module structure of this embodiment 1. The heat dissipation fans in the figure are circular and there are two of them, which are respectively located on both sides of the heat dissipation cover. The centers of the two heat dissipation fans are located on the same straight line. The heat dissipation cover is a rectangular cover-shaped structure, which is hollow inside. The heat dissipation cover is covered and fixed on the surface of the heat dissipation shell.

[0035] There are also multiple heat pipes attached to the inner surface of the heat dissipation shell. These heat pipes are arranged in a crisscross pattern to quickly transfer the heat generated by the heat source to the heat dissipation cover. The heat pipe has excellent thermal conductivity and can transfer heat to the cooling fan in a very short time, ensuring that the device can remain stable when running at high load.

[0036] The blade design of the cooling fan has been carefully optimized and adopts the principle of aerodynamics, so that the fan can generate greater wind pressure and air volume when rotating. The speed of the fan can be adjusted by the intelligent temperature control system, which adjusts the fan speed in real time according to the temperature inside the device to achieve the best cooling effect.

[0037] The bottom of the heat sink is also designed with an air inlet for introducing external cold air. When the cooling fan is working, the cold air enters the heat sink from the air inlet, passes through the heat pipe heat conduction system, and is then discharged from the heat sink. This forms an effective heat dissipation cycle, which can quickly discharge the heat inside the device and ensure the stable operation of the device.

[0038] The outermost part of the heat dissipation fan is an annular fan outer ring, and the central part of the heat dissipation fan is a circular fan inner ring. The inside of the fan inner ring is fixed to the heat dissipation shell, and a fan motor is fixed inside the fan inner ring, and a plurality of fan blades are arranged between the fan outer ring and the fan inner ring.

[0039] The cooling fan is designed to be sophisticated and efficient, and its structure fully considers aerodynamics and heat dissipation efficiency. The outer ring of the fan, as the support and fixing part of the entire fan, is made of strong and lightweight materials, which not only ensures the stability of the fan but also reduces the overall weight. The inner ring of the fan is directly fixed to the heat dissipation shell, ensuring a close connection between the fan and the heat dissipation system, making the heat dissipation effect even better.

[0040] The fan motor is the core component of the cooling fan, which is responsible for driving the rotation of the fan blades to generate a strong wind flow. The fan motor uses advanced electronic control technology, which can intelligently adjust the fan speed according to the operating status of the computer, ensuring the cooling effect while reducing noise and energy consumption.

[0041] The fan blades are a key part of the cooling fan, and their design directly affects the generation of wind flow and the cooling effect. These blades adopt a special aerodynamic design, which can rotate quickly under the drive of the fan motor, sucking in the surrounding air and blowing it out forcefully, thereby effectively reducing the temperature of the heat source.

[0042] The fan blades are integrally formed with the fan outer ring and the fan inner ring, and the fan blades are equidistantly distributed on a circle with the fan inner ring as the center.

[0043] The fan is uniquely designed and highly efficient. This one-piece structure not only enhances the overall stability of the fan, but also greatly reduces wind resistance and noise. The fan blades are evenly spaced around the inner circle of the fan, allowing the wind to be evenly and quickly dissipated, greatly improving the fan's working efficiency.

[0044] In addition, the fan material has been carefully selected to meet the strength requirements while taking into account lightness and durability. Therefore, the fan blades, outer ring and inner ring are all made of a high-strength and lightweight composite material, which has excellent fatigue resistance and corrosion resistance and can operate stably in various harsh environments.

[0045] Reference Figure 4 This is a schematic side view of the heat dissipation module structure of this embodiment 1. In the figure, the heat dissipation module is arranged in the order of heat dissipation cover-heat dissipation shell-heat dissipation plate-liquid cooling plate, and is threadedly connected. A liquid inlet and a liquid outlet are provided in the liquid cooling plate, and heat dissipation grooves are provided at both ends of the heat dissipation shell. The cross-section of the heat dissipation groove is triangular, which is used to fix the internal structure of the heat dissipation module and also to fix the heat dissipation module at the heat source.

[0046] Reference Figure 5This is a schematic front view of the heat sink structure of Embodiment 1, in which there are two heat sinks, and the heat sink comprises a rectangular heat sink frame, a mesh plate net is provided inside the heat sink frame, and the two heat sinks are overlapped and fixed, and the liquid cooling plate matches the heat sink, and the liquid cooling plate and the heat sink are overlapped and fixed.

[0047] This design maximizes the contact area between the heat sink and the liquid cooling plate, thereby improving the heat dissipation efficiency. When the device generates heat during operation, the heat is first transferred to the liquid cooling plate. The plate mesh design on the heat sink helps to increase the heat dissipation area, allowing the heat to be transferred from the liquid cooling plate to the heat shield more quickly and dissipated by the cooling fan.

[0048] In addition, the overlapping placement of the two heat sinks further enhances the heat dissipation effect. This structure not only provides a larger heat dissipation area, but also ensures the stability of the heat dissipation system through the fixed connection between the two heat sinks. At the same time, the overlapping placement and fixed connection between the heat sink and the liquid cooling plate enable the heat to be directly and effectively transferred to the cooling fan.

[0049] The liquid cooling plate is usually filled with liquid with good thermal conductivity, which takes away the heat during the circulation process, thereby achieving a cooling effect. Through close cooperation with the heat sink, the liquid cooling plate can quickly absorb the heat from the heat sink and transfer it to the cooling system, and finally discharge the heat outside the device.

[0050] This heat dissipation structure is designed to improve the heat dissipation performance of electronic equipment and ensure that the equipment can maintain a stable temperature when running at high loads, thereby extending the service life of the equipment and improving performance stability.

[0051] Reference Figure 6 This is a schematic diagram of the main view of the dehumidification module structure. The dehumidification module in the figure includes a rectangular assembly plate. The surface of the assembly plate is provided with air guide mesh holes, and the air guide mesh holes penetrate the assembly plate. An air guide cover is fixed to the periphery of the assembly plate. The cross-section of the air guide cover is triangular, the interior of which is hollow, and the bottom surface is connected to the interior.

[0052] A fan is also provided on one side of the assembly plate, and the fan is connected to an external power source through a wire. A condenser is provided on the other side of the assembly plate, and the condenser is connected to an external refrigerant source through a pipe. When dehumidification is required, external air enters the air guide mesh through the air guide cover, and then is sucked by the fan to guide the air into the condenser. The refrigerant inside the condenser cools the air, condenses the water vapor in the air into water droplets, and the water droplets are discharged through the pipe to achieve the dehumidification effect.

[0053] In addition, in order to achieve a more ideal dehumidification effect, a heating wire can be added inside the assembly board. When the air temperature is too low, the heating wire will automatically start to heat the air to prevent frost on the condenser surface and ensure the dehumidification effect. At the same time, in order to facilitate users to understand the working status of the dehumidification module, a display screen can be set on the assembly board to display the current humidity, temperature and other information.

[0054] A condenser is arranged on the other side of the assembly plate, and an exposed condensation joint is arranged on one end of the condenser.

[0055] exist Figure 1 , Figure 2 , Figure 6 On the basis of the above, the main technical solutions such as shape, structure, position relationship, connection relationship in Example 1 were further refined and verified according to actual installation to obtain Example 2. This Example 2 is also a split liquid cooling unit, and also includes a host module and a control module, which are independent components. The control module integrates the control circuit and chip, and is connected to the host module, the dehumidification module, and the heat dissipation module to control the power of the host module, the dehumidification module, and the heat dissipation module and adjust the working parameters of different heat dissipation modules, so as to achieve the purpose of controlling and adjusting multiple different heat dissipation modules using only one control module, thereby simplifying the control circuit and saving control costs.

[0056] The host module integrates a compressor, an expansion valve, a PTC, a water pump, a refrigerant source and multiple functional plate heat exchangers. The host module is connected to the heat dissipation module and the dehumidification module through a hose. The heat exchange of the host module is provided to the heat dissipation module and the dehumidification module through the hose, and the heat is taken away by the heat dissipation module, and refrigerant is provided to the dehumidification module at the same time.

[0057] The beneficial effects of the first and second embodiments are as follows:

[0058] The dehumidification module solves the condensation problem of the heat dissipation module and other heating parts and has a good dehumidification effect. Secondly, the utility model adopts a split structure to reduce the overall configuration cost and control cost of the liquid cooling unit. The modular design, modular replacement, and flexible assembly can realize diversified functional requirements. The highly integrated modularization reduces the occupied space of the liquid cooling system and improves space utilization.
