The present invention discloses a heat spreader and method for making the heat spreader. The heat spreader comprises: a hollow metallic housing including an upper cover having an inner surface and a lower cover having an inner surface, the upper and lower covers being bonded together along their perimeters defining a cavity; a capillary structure in a form of metallic meshes bonded to the inner surfaces of the upper and lower covers of the metallic housing; a plurality of reinforcing members disposed in the cavity and bonded between the inner surfaces of the upper and lower covers of the metallic housing; and a working fluid receive in the cavity; wherein bonded surfaces between the metallic meshes and the inner surfaces of the metallic housing, the upper cover and the lower cover, and the reinforcing members and the inner surfaces of the metallic housing all are diffusion-bonded interfaces. |
