[0002] At present, generally high-power heating elements adopt liquid cooling to dissipate heat, such as power modules and various semiconductor heating elements, but the shapes of various heating elements are different, and there are different requirements for the size of the radiator, especially some high-power semiconductor lighting The shape of equipment, such as high-power LEDs, is ever-changing, so there are also different requirements for the size of the radiator. How to quickly and cost-effectively manufacture a heat dissipation component of an appropriate size is a problem that currently exists

[0003] CN201210532398 patent discloses a cooling system suitable for high-power LED lamps, including a radiator and a water-cooled driving device. The radiator is a columnar structure with a cavity. One end of the radiator is provided with a liquid inlet, and the other end is provided with a One liquid outlet; the water-cooled driving device is connected to the liquid inlet and outlet of the radiator through water pipes or only connected to the liquid inlet of the water-cooled driving device; although the heat dissipation system has good heat dissipation effect, energy saving, low cost, safety and environmental protection and other advantages, but because the radiator is a fixed shape, it can only be applied to heating equipment whose shape and size are compatible with it
