Embodiment Construction

[0037] The following non-directional vapor chambers based on preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification, even in mutually different embodiments, the same or similar reference numerals are assigned to the same or similar structures, and the descriptions of these parts are replaced by the original descriptions.

[0038] figure 1 It is a schematic exploded perspective view illustrating a non-directional vapor chamber 100 according to an embodiment of the present invention.

[0039] It can be seen from the drawings that the non-directional vapor chamber 100 is generally composed of an upper plate 110 and a lower plate 130 .

[0040] The upper plate 110 and the lower plate 130 are each formed of a rectangular flat plate. Its structure can be made of metal material, for example, it can be made of copper alloy. The upper plate 110 and the lower plate 130 may have the same size and sh...

Abstract

The present invention provides a non-oriented vapor chamber. The non-oriented vapor chamber comprises: a top plate having a first structural surface; a lower plate having a second structural surface facing the first structural surface; a macro channel formed on at least one of the first structural surface and the second structural surface by an etching process, and forming a passage through whicha gaseous working fluid flows from an evaporation part to a condensation part by thermal energy; and a micro channel formed on at least one of the first structural surface and the second structural surface by the etching process to have a groove having a width smaller than that of the macro channel, disposed between an adjacent pair of macro channels, and forming a passage through which a liquid working fluid moves from the condensation part to the evaporation part by capillary force, wherein the macro channel includes an outer heat radiation channel occupying at least a part of an outermost channel on the upper plate or the lower plate.

Description

technical field [0001] The present invention relates to a non-directional vapor chamber for removing heat from a heat source. Background technique [0002] A vapor chamber (Vapor Chamber) is a device that removes heat from an object by utilizing the latent heat at the time of phase transition between liquid and gas. Vapor chambers have the advantage of being able to quickly remove and discharge heat from the object as a method different from the general heat transfer system (conduction, convection, and radiation). [0003] Most of the existing vapor chambers are designed to operate in a single direction. Specifically, the heat source is located in the lower portion of the chamber, and gas vaporized by the heat source rises to condense into a liquid at a condensation section provided in the upper portion of the chamber. The condensed liquid drips again to the heat source side of the lower part by gravity. [0004] On the other hand, in order to operate the vapor chamber wi...
