Abstract: A multi-tube parallel heat spreader has at least three conduits disposed in parallel; a first connector fitted onto the first end of each conduit, with one side of the first connector configured with a first connecting plughole for the first end of each conduit to be inserted into, and a first connecting passage inside the first connector that is communicated to each first connecting plughole; a second connector fitted onto the second end of each conduit, with one side configured with a second connecting plughole for the second end of each conduit to be inserted into, and a second connecting passage inside the second connector that is communicated to each second connecting plughole; a working fluid contained in the vacuum interior of each conduit and the first and second connector; a heat conduction base abutting and combined with the conduits, including a heat conductive surface and a supporting surface.

Abstract: A temperature-uniforming plate with supporting effect includes a base plate and a cover plate mounted onto the base plate, wherein a frame is sandwiched between the base plate and the cover plate to define a vacuum chamber among the base plate, the cover plate and the frame. The frame has two arms inwardly extending therefrom and extending to a heat conducting area formed on the base plate. A passage is defined between the two arms. The two arms are clamped between a top surface of the base plane and a bottom surface of the cover plate. The temperature-uniforming plate has a thinning and simplified structure for easily formed, reducing manufacturing cost and providing a supporting effect.
