The Advantages of the Liquid - Cooled Load Bank in Data Centers

The liquid - cooled load bank uses liquid as the cooling medium, and its heat - dissipation efficiency has a qualitative leap compared with the traditional air - cooling method. The specific heat capacity of liquids is usually much larger than that of air. Taking water as an example, the specific heat capacity of water is about 3400 times that of air, which enables the same mass of liquid to absorb more heat. At the same time, the thermal conductivity of liquids is also much higher than that of air. The thermal conductivity of water is nearly 25 times that of air, which can transfer heat more quickly.

In data centers, key components such as the CPU and GPU of servers generate a large amount of heat during operation. The liquid - cooled load bank, through methods such as cold - plate and immersion, allows the coolant to directly contact these heat - generating components, reducing the thermal resistance in the heat - transfer process and achieving precise cooling. In contrast, air - cooling heat dissipation relies on air convection, and the heat - transfer speed is slow, and local hot - spots are likely to form. The liquid - cooled load bank can quickly take away the heat from the heat source, ensuring that the key components of the server are always at an appropriate operating temperature, effectively avoiding performance degradation or failures caused by overheating and ensuring the stable operation of the data center.​

(2) Energy - consumption Reduction​

The energy consumption of data centers has always been an important part of operating costs, and the energy consumption of the heat - dissipation system accounts for a relatively high proportion. The liquid - cooled load bank can significantly reduce the energy consumption of data centers with its high - efficiency heat - dissipation performance. On the one hand, due to its high heat - dissipation efficiency, it can quickly exhaust the heat generated by the servers, so that the servers do not need to consume excessive energy to operate their own cooling fans and other devices to maintain normal temperatures. On the other hand, after adopting the liquid - cooled load bank, the dependence of the data center on large - scale air - conditioning systems is reduced. The traditional air - cooled data center mainly relies on the air - conditioning system for air cooling, and the energy consumption of the air - conditioning system is huge. The liquid - cooling technology can reduce the dependence on the air - conditioning system and reduce the operating time and energy consumption of the air - conditioner. For example, by pre - cooling through the liquid - cooling system and then cooperating with the air - conditioner, or completely replacing the air - conditioning system in some scenarios, the cooling energy consumption of the data center can be significantly saved. According to relevant data statistics, the overall energy consumption of data centers using liquid - cooling technology can be reduced by 30% - 50% compared with traditional air - cooled data centers, greatly reducing operating costs and also conforming to the current environmental - protection concept of energy conservation and emission reduction.​

(3) Space Saving​

In data centers, space resources are very precious. The liquid - cooled load bank can be more compactly arranged on the server rack, effectively improving the space utilization rate. Different from the traditional air - cooling method, the liquid - cooling system does not require a large amount of space to arrange complex air ducts and large - scale cooling fans and other devices. It realizes high - efficiency heat dissipation by directly introducing the coolant into the server or the cabinet, reducing the extra space occupied due to heat - dissipation requirements. Take a large - scale data center as an example. After adopting the liquid - cooled load bank, a large amount of space originally occupied by air - cooling equipment was released, enabling the data center to increase the number of server deployments by 20% - 30% without expanding the site area, greatly enhancing the computing power and business - carrying capacity of the data center and creating greater value for enterprises.​

(4) Ultra - quiet Operation​

In the traditional air - cooling system of data centers, the continuous high - speed rotation of fans can generate noise of about 70 decibels. This not only interferes with the working environment of operation and maintenance personnel, and long - term exposure to such a noisy environment may also cause damage to hearing, but also affects the normal operation of the equipment. The liquid - cooled load bank adopts advanced liquid - cooling circulation technology, abandoning the traditional heat - dissipation mode relying on fans. During operation, the noise can be controlled at a very low level, usually reaching the quiet - environment standard similar to that of a library, generally below 35 decibels. For example, the rack - mounted liquid - cooled load of Kaixiang Technology can create a quiet working environment for the data center when running at full load, allowing operation and maintenance personnel to work more comfortably and efficiently. At the same time, it also reduces the vibration impact of noise on the electronic components of the equipment and extends the service life of the equipment.
