[0002] With the continuous development of electronic devices and industrial instruments, especially the increasingly widespread application of high-power and high-integration devices, the heat dissipation problem has become a key technical problem that needs to be solved urgently. A large amount of heat is generated when high-power devices are working. If it is not dissipated in time and effectively, the device temperature will rise, even exceeding its allowable operating temperature range, which will damage the device and affect the stable operation of the equipment.
[0003] In heat dissipation technology, the selection of heat-conducting materials is crucial. Common heat-conducting materials include silver, copper, aluminum, etc., and their heat-conducting performance decreases in turn. Silver has the best heat-conducting performance, but its cost is high and it is not suitable for large-scale application. As a heat-conducting material with relatively high cost performance, copper is widely used in the manufacture of radiators due to its excellent heat-conducting performance and moderate cost.
[0004] Although traditional copper tubes have certain advantages in heat-conducting performance, they often face problems such as insufficient strength, easy deformation or damage under complex working conditions, such as high-pressure and large-temperature-difference environments.
