Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a phase-change heat-conducting radiator comprises a radiator body 1, wherein the radiator body 1 comprises a metal cylinder 3 and radiating fins 4, and the metal cylinder 3 and the radiating fins 4 are both made of aluminum or copper; the radiating fins 4 are arranged on the outer wall of the metal cylinder 3, and a plurality of radiating fins are distributed on the outer wall of the metal cylinder 3, so that the radiator is large in radiating contact area and can improve heat exchange efficiency; the inner cavity of the metal cylinder 3 is a heat exchange cavity 5, the inner wall of the metal cylinder is provided with a heat dissipation rib and a rib groove formed by the heat dissipation rib, a proper amount of volatile liquid is required to be filled in the heat exchange cavity as a medium, and the inner wall of the heat exchange cavity is provided with the heat dissipation rib, so that more heat exchange area is ensured; one end of the metal cylinder 3 is provided with a through hole, a heat conduction assembly is arranged at the through hole, the other end of the metal cylinder 3 is provided with a through hole, and an upper cover 6 is arranged at the through hole.

The working principle is as follows: when the heat conducting plate is heated, the liquid in the capillary core contacted with the heat conducting plate is quickly vaporized and distributed in the closed heat exchange cavity. At this time, the heat dissipation ribs in the heat exchange cavity exchange heat with the gas and conduct the heat to the radiator, and then the heat is dissipated. The gas heat is converted into liquid after exchanging heat with the heat dissipation ribs, and the liquid is absorbed by the capillary core for cyclic evaporation. This reduces the heat source to heat sink temperature difference.
