With the development of science and technology, mechanization is getting higher and higher; The power of the equipment is increasing, and the heat produced by high power is also increasing. However, when excessive heat is accumulated and not discharged in time, the equipment will be damaged. And Water-cooled cooling is an appropriate cooling method at present.
Two main ways of water cooling: immersion water cooling and water cooling plate
Immersion water cooling
Immersion cooling completely immerses the equipment or electronic components in a heat-conducting but insulating liquid coolant. By making the coolant directly contact with the hot parts and circulating the heated liquid through the heat exchanger, the heat energy is removed from the equipment and the liquid coolant is returned to a sufficiently low inlet temperature. This method is very effective because liquid coolant can absorb more heat from the system and circulate more easily in the system than air.
However, the immersion cooling system must be customized according to the equipment, and a large amount of facility investment is required to integrate it into a large-scale complete thermal management ecosystem.
Water cooling plate
The water cooling plate is directly installed on the high power frame assembly to distribute the coolant to the high thermal power discharge area. With the rapid development of computing requirements and components, this more traditional cooling method can be more easily merged and upgraded. In cold plate technology, the heat transfer performance may be significantly different, which depends on the internal design of the coolant flow, and the performance change is easier to quantify. Compared with immersion cooling, it requires less cost and is suitable for a wide range of applications.
Working principle of water-cooled plate
The metal plate (typically aluminum or copper) that possesses internal tubing to allow liquids to flow through it. When a cold plate is placed on an electronic component that requires cooling, it absorbs and dissipates the heat from the component to the liquid that is then cycled through the system.
The flow paths inside the cold plates can be machined in various shapes and sizes, and can allow cold plates to more effectively absorb and transfer large amounts of heat.
The advantage of water cooling plate
Energy and system efficiency: The lower power required by the water-cooled plate cooling system makes it more efficient, reduces energy consumption, and reduces costs and carbon.
Improve reliability: the water-cooled plate cooling system can ensure more effective heat dissipation and temperature control, so that the components can work in the best environment and have higher reliability.
Greater design flexibility: the water-cooled plate can be designed into various shapes and sizes through different processes according to the heat dissipation requirements.
More efficient heat transfer: compared with heat pipe, the liquid-cooled plate can directly transfer heat on the large plate, thus achieving more effective heat transfer.
High safety factor: most liquid-cooling plate are made of aluminum alloy and various insulating media. Eliminates potential safety hazards in electrical applications.
Less noise: water-cooled plate heatsink use water as the medium, and the cooling system is quieter than the air cooling system.
Application of water-cooled plate in various industries
Liquid cooling plate in data center
The development of cloud computing has promoted the rise of data centers. However, the rapid expansion of data centers and increasing energy consumption require more efficient cooling solutions.
In the early days, the data center used air-cooled cooling scheme, but today's power density of the data center is close to the upper limit of the cooling capacity of the air-cooled system.
In addition, the high-density data storage system also has a heating problem, because the updated design compresses more memory devices into smaller volumes, thus preventing the optimal data read/write speed.
Data centers consume a large amount of energy, which currently accounts for about 3% of global electricity. As the energy price fluctuates with the uncertainty of the market, water cooling plates do not require as much power for heat dissipation as air-cooled, which can greatly reduce operation.

Liquid cooling plate in EV
With the rapid progress of technology and people's pursuit of environmental awareness, electric vehicles are constantly developing and improving. They are now more powerful, able to carry out longer distances and use more airborne computing.
As electric vehicles become more powerful and efficient, more and more heat loads will be generated in smaller and smaller parts.
Thermal limitations affect efficiency, power, safety, reliability, driving distance and other performance characteristics that are critical to consumers.
Poor thermal management of batteries, whether resulting in high or low temperature, will reduce battery capacity and performance, and even increase combustion, safety and reliability risks. The liquid cooling of electric vehicle battery is usually used to control the temperature and keep it in the best working range.
In order to meet the requirements of electric vehicles, awind's water cooling plates are lightweight, small in size, efficient in heat conduction, and maintain a low operating temperature at the lowest cost, thus improving the overall energy budget and vehicle efficiency.
Liquid cold plate in IGBT
IGBT plays an important role in power transmission and conversion, but they can also generate high level of heat during high-frequency switching. The main priority of power designers is the cooling of IGBT devices.
Awind customized IGBT liquid cooling solution helps you improve the power performance, electrical efficiency, safety and reliability of power electronic systems.
The liquid cooling heat sink plate improves the heat transfer coefficient, reduces the thermal resistance of the system, and increases the power capacity of the IGBT. The water-cooled plate can be designed to achieve greater power per unit volume, thus improving performance and energy efficiency
Water cooling plate in laser
The laser generates a lot of heat energy during operation. Even the most efficient laser cannot convert all energy into light output, so the excess energy will be converted into heat. Lasers with lower power levels can usually manage waste heat by passive cooling or natural airflow. On the other hand, high-power lasers need more active cooling strategies. Water-cooled plate cooling is usually an effective solution.
Our cold plate dissipates heat evenly and efficiently to maintain the best performance of the laser system.
