In the field of new energy, the normal operation of aluminum alloy radiators is crucial for the heat dissipation and stable operation of equipment. It takes a combination of multiple methods and careful observation to determine whether there is a leakage problem.
First, you can perform an appearance inspection. Carefully check the surface of the radiator, including welds, interfaces, joints and other parts. If there is a leak, water stains, rust or oil stains may be found at these locations. Because the leaking liquid may bring out impurities and moisture inside the radiator, leaving marks on the surface. Especially in welds and joints, tiny cracks or pores may cause leaks. If you find abnormal color changes, corrosion spots or obvious damage, they may be signs of leakage.
Secondly, pressure testing is an effective method. You can use special pressure testing equipment to fill the radiator with a certain pressure of gas or liquid. While maintaining the pressure for a period of time, observe whether the pressure is stable. If the pressure drops rapidly, there is a high probability of leakage. This method can detect even tiny leaks more accurately, but it should be noted that when performing pressure testing, make sure that the pressure is within the safe range that the radiator can withstand to avoid additional damage.
In addition, it can also be judged by detecting temperature distribution. Under normal working conditions, use a thermal imager to scan the radiator. If there is a leak in the radiator, the temperature distribution of the leaking part may be abnormal. Because the leak will affect the heat dissipation effect, causing the local temperature to be too high or too low, forming a significant temperature difference with other normal areas. Through the temperature difference in the thermal image, it is possible to preliminarily determine whether there is a leak and the approximate location of the leak.
In addition, paying attention to the operating status of the equipment is also an indirect judgment method. If the new energy equipment frequently has overheating alarms, performance degradation or instability during use, and other factors that may cause overheating have been eliminated, then it is necessary to consider whether the radiator has a leak problem, resulting in poor heat dissipation.
Finally, liquid detection can be performed. For some radiators that use liquid as a cooling medium, if a leak is suspected, the liquid flowing out of the radiator can be collected and analyzed and tested. Check whether the liquid contains impurities, bubbles or abnormal chemical components, which may be caused by leakage.
In short, judging whether the New Energy Aluminum Alloy Radiator has a leak problem requires the comprehensive use of multiple methods, and analysis and judgment from multiple angles such as appearance, pressure, temperature, equipment operating status, and liquid detection. Timely discovery and resolution of leakage problems can ensure the normal operation of the radiator and the stable operation and service life of new energy equipment. For example, in a maintenance case of a new energy vehicle, a visual inspection revealed slight water stains at the radiator interface. Further pressure testing confirmed the presence of a leak, and timely replacement of the seal solved the problem, avoiding vehicle failure due to overheating.
