[0002] As an integral part of the thermal management field, radiators are mainly used to effectively dissipate heat from heat sources (such as electronic components, engines, industrial equipment, etc.) to the surrounding environment, thereby ensuring the stable operating temperature of the equipment or system. In various application scenarios, whether it is consumer electronics or large industrial facilities, effective heat dissipation measures are crucial for maintaining performance and prolonging service life.

[0003] Traditional radiator designs usually take the form of a single unit, which achieves heat exchange through conduction, convection, or radiation. However, when it comes to large-area heat dissipation requirements, traditional methods expose a series of problems. First, in cases where a larger heat dissipation area is needed, the usual approach is to arrange multiple radiators and individually bolt them down. This method not only makes the installation process cumbersome and inconvenient, but also increases labor and time costs. In addition, as the heat dissipation area increases, the amount of air entering the alternating cold and hot regions also increases, which makes it easier for dust and other impurities to be drawn into the large-area heat dissipation system. Long-term accumulation can further affect the heat dissipation effect, and even cause equipment overheating and damage. Therefore, it is necessary to design a radiator with expandable and splicing heat dissipation surfaces to solve the above problems. SUMMARY
