Solving the Pain Points of Traditional Air-Cooling! Liquid Cooled Load Bank Unlocks a New Testing Experience

Time:2025-09-18
​In the field of high-power equipment testing, traditional air-cooled load banks have long been limited by heat dissipation bottlenecks, with their pain points becoming increasingly prominent. During high-power operation, air-cooled systems rely on a large amount of cold air for convective heat dissipation. Not only does the fan noise exceed 60 decibels, affecting the working environment, but they are also prone to dust accumulation that clogs heat dissipation channels, leading to frequent high-temperature alarms of the equipment. More critically, the heat dissipation efficiency of air-cooling is limited—when the equipment power density exceeds 30W/cm², temperature runaway occurs, resulting in a test data deviation of more than 5%. This seriously affects test accuracy and even forces test interruptions.​

The emergence of the liquid cooled load bank has precisely solved these problems. It adopts a closed-circuit heat conduction system, using high-efficiency heat-conducting media to directly contact heat-generating components. Its heat dissipation efficiency is more than 3 times higher than that of air-cooling. Even when the equipment power density reaches 80W/cm², it can still control the temperature within ±1℃, completely eliminating high-temperature interference. At the same time, the closed design prevents dust from entering, eliminating the need for frequent cleaning and maintenance, and reducing equipment failure rates by 60%. The fanless structure lowers the operating noise to below 30 decibels, creating a quiet testing environment.​
In practical applications, the liquid cooled load bank also offers the advantage of flexible adaptability. It can be customized with modular load units according to the needs of different equipment such as servers, charging piles, and frequency converters, supporting testing in the power range of 10kW-200kW. After a new energy enterprise adopted it, the testing efficiency increased by 40%, and the original 2-day charging pile test was shortened to 1 day, significantly reducing time costs. With its characteristics of "low noise, high efficiency, and stability," the liquid cooled load bank is unlocking a brand-new experience for high-power equipment testing.
