Example Embodiment
[0022] The present invention will be further described below in conjunction with specific embodiments.
[0023] An LED radiator based on heat pipe technology, comprising a gravity heat pipe arranged in the center and a sun flower-shaped radiating fin 4 arranged around the gravity heat pipe. The gravity heat pipe includes a middle through pipe 1 and an upper cover 2 and a bottom cover 3. The middle through tube 1 is welded to the upper cover 2 and the bottom cover 3 to form a vacuum, and a refrigerant 5 is filled in the middle. The heat dissipation fins 4 are arranged around the through tube 1 and the bottom cover 3 is The part of the surface located in the through pipe is provided with a uniformly distributed multi-point protruding grooved milk structure 6, a sealing hole 7 is arranged in the middle of the upper cover 2, and the bottom of the bottom cover 3 is connected with the LED lamp.
[0024] The sealing hole 7 includes a lower inverted tapered hole section 71, a middle rectan...
