At a time when energy storage technology is changing with each passing day, energy storage equipment has been widely infiltrated into every corner of the energy industry, from huge energy storage power stations to providing power support for electric vehicles, and then to becoming a reliable guarantee for emergency power supply for families. Its importance is self-evident. However, the continuous increase in the power density of energy storage systems has brought severe heat dissipation challenges. The heat dissipation effect is directly related to the performance, life and safety of energy storage equipment. As one of the core components of the heat dissipation system, the energy storage heat sinks shell is becoming the key focus of the industry to break through the heat dissipation bottleneck.
The traditional energy storage heat sinks shell has obvious shortcomings in structural design. Its structural structure is relatively simple, and the heat dissipation fins, as key heat dissipation components, lack detailed consideration and optimization in quantity setting, shape planning and arrangement layout. This extensive design makes the air flow between the heat dissipation fins poor, and it is impossible to fully exert the efficiency of taking away heat, which easily leads to local hot spots when the battery pack is working. Taking some energy storage equipment that was put into use early as an example, the spacing between the heat dissipation fins of its radiator shell is too large. In this case, although the air encounters less resistance when circulating and can pass smoothly between the fins, the actual contact area between the air and the fins is limited, and the heat carried by each air flow is negligible, and the overall heat dissipation efficiency is greatly reduced. On the contrary, the spacing between the heat dissipation fins of some other devices is too small. When the air moves in the gap between the fins, it is very easy to get blocked. The air cannot flow freely along the expected path, and the heat dissipation channel is blocked. It is also difficult to achieve efficient heat dissipation, which makes the problem of excessively high local temperature of the battery pack frequently occur.
Faced with the various deficiencies in the structural design of the traditional energy storage heat sinks shell, scientific researchers and industry practitioners actively explored, and the research and development and application of new materials are like a ray of light, opening up a new path for overcoming the heat dissipation problem. In the field of metal materials, a series of new alloy materials have been introduced one after another, injecting strong impetus into the upgrading of energy storage heat sinks shells. Among them, aluminum alloy materials containing special trace elements are particularly outstanding. Compared with traditional ordinary aluminum alloys, the thermal conductivity of this type of new aluminum alloy has been significantly improved. During the operation of energy storage equipment, when the battery generates a lot of heat, the radiator shell made of new aluminum alloy can quickly transfer the heat inside the battery to the surface of the shell with its excellent thermal conductivity, greatly shortening the time of heat transfer and gaining an advantage for the subsequent heat dissipation link.
In addition to excellent thermal conductivity, this type of new alloy material also has good strength and corrosion resistance. In actual application scenarios, energy storage equipment may face various complex and harsh environmental conditions. Whether it is an outdoor environment with high temperature and high humidity, or an industrial site with the risk of chemical corrosion, the radiator shell made of new alloy materials can rely on its strong structural strength to resist possible physical impact from the outside world and ensure the integrity of its own structure. At the same time, its excellent corrosion resistance enables the radiator shell to work stably when facing corrosive substances, effectively extending the service life of the radiator shell and reducing the maintenance cost and replacement frequency of the equipment.
From the actual application effect, the energy storage heat sinks shell using new alloy materials has shown obvious advantages in many aspects. In large energy storage power stations, traditional radiator shells are often unable to cope with the large amount of heat generated by high-power charging and discharging, resulting in large temperature fluctuations in the battery pack, affecting the overall operating stability of the energy storage power station. Energy storage power stations using new alloy material shells can effectively control the temperature of the battery pack and keep it within a relatively stable range. According to relevant research data, under the same high-load operating conditions, the average temperature of the battery pack of energy storage power stations using new alloy radiator shells is 5℃ - 8℃ lower than that of power stations using traditional shells. This temperature reduction plays a vital role in improving the charging and discharging efficiency of the battery and extending the battery life.
In the field of electric vehicles, the performance of the energy storage heat sinks shell also directly affects the vehicle's range and safety. During the driving process of electric vehicles, the battery continuously discharges and generates heat. If the heat is not dissipated in time, it will not only reduce the energy conversion efficiency of the battery, but also may cause safety hazards. The radiator shell made of new alloy materials can quickly dissipate the heat of the battery, ensuring that the battery works at a suitable temperature, thereby improving the performance stability of the battery. According to experimental tests, after an electric car equipped with a new radiator shell has been driving continuously at high speed for 100 kilometers, the battery temperature is about 10°C lower than that of a vehicle using a traditional radiator shell, and the cruising range has been improved by 5% - 8%.
In terms of home energy storage systems, the advantages of the new energy storage heat sinks shell are also significant. Home energy storage equipment is usually installed indoors, and the safety and stability of the equipment are extremely high. The high strength and corrosion resistance of the new alloy material ensure that the radiator shell will not be damaged by environmental factors during long-term use, avoiding possible safety risks. At the same time, its efficient heat dissipation performance can ensure that the home energy storage equipment always maintains a stable working state when supplying power to the home, providing reliable protection for home electricity use.
