Abstract:
A heat-dissipating plate has a casing and a supporting structure, where the casing has surrounding walls to define a receiving compartment therein confined by an inner wall. The inner wall is integrated with a capillary structure. Disposed inside the receiving compartment, the supporting structure includes a meshed partition and a plurality of columns. The meshed partition has a plurality of holes and joined-openings. The columns are fixed in the joined-openings and abut against the inner surface of the walls. The associated manufacturing process for the heat-dissipating plate is easily to accomplish.
Abstract:
A method includes forming a gate stack over a semiconductor substrate, wherein the gate stack includes a gate dielectric and a gate electrode over the gate dielectric. A portion of the semiconductor substrate adjacent to the gate stack is recessed to form a recess. A semiconductor region is epitaxially grown in the recess. The semiconductor region is implanted with a p-type impurity or an n-type impurity. A dry treatment is performed on the semiconductor region.
Abstract:
The flattened heat pipe includes a flattened tube, a first wick structure, a second wick structure and a working fluid. The flattened tube has an annular wall and a chamber formed within the annular wall. The first wick structure is disposed on a portion of the annular wall. The second wick structure is disposed on another portion of the annular wall, and not overlapping with each other. The working fluid is filled in the chamber.
Abstract:
The heat pipe of the invention includes an evaporation section and two condensation sections. The evaporation section is located at a part of the heat pipe. The two condensation sections are separately located at two opposite sides of the evaporation section. The evaporation section and the two condensation sections communicate with each other, and a peripheral size of the evaporation section is larger than that of each of the condensation sections.
Abstract:
A vapor chamber includes a first board, a second board sealed with the first board, and a cavity formed between the first and second boards, and the cavity contains a first support arm and a second support arm corresponding to the first and second boards respectively, and the first support arm and the second support arm are engaged with each other along the first and second boards and arranged adjacent to each other. With the engagement of the first and second support arms, the first and second boards of the vapor chamber can be supported and pulled to achieve effect of preventing the first and second boards from being recessed or protruded.
Abstract:
A heat pipe includes a step pipe and a sintered powder structure. The inner wall of the step pipe has a plurality of grooves. The step pipe has an evaporating section and two condensing sections. The condensing sections are on the two ends of the step pipe, respectively. The evaporating section lies between the two condensing sections. The inner spaces of the two condensing sections and the evaporating section are interconnected. The peripheral dimension of the evaporating section is larger than the peripheral dimension of each of the condensing sections. The sintered powder structure is bounded inside each of the condensing sections, improving the heat pipe's inner air flow rate and heat conduction efficiency.
Abstract:
A folding vapor chamber includes folding boards engaged and covered with one another, a folding edge formed between the adjacent folding boards and provided for connecting the folding boards integrally, and the adjacent folding boards being bent and folded by the corresponding folding edge and engaged with one another, and a capillary tissue installed at an internal surface between the folding boards. The casing is formed by the folding edge to reduce the length of the sealing edge of the vapor chamber, so as to achieve the effects of lowering the defective rate of the edge sealing operation, and preventing the sealing edge from being cracked easily.
Abstract:
A heat-dissipating plate includes a casing and partition insert. The casing has surrounding walls with wick structures therein, and the inner surface of the walls defines a receiving compartment. The partition is disposed in the receiving compartment. The partition has a plurality of hole, a plurality of flanges protruding from an edge of the holes respectively. Each of flanges has a plurality of arc-shaped flange-rim extending outward to support the inner surface of the surrounding wall.
Abstract:
A method for enclosing a heat pipe with metal is disclosed. The method includes the steps of: a) providing a tube made of a metal; b) putting the heat pipe in a hollow of the tube; and c) stretching the tube to shrink an inner diameter of the tube for tightly enclosing the heat pipe.
Abstract:
A heat pipe includes a step pipe, a mesh, and a supporting component. The step pipe has an evaporating section and two condensing sections. The condensing sections are on the two ends of the step pipe, respectively. The evaporating section lies between the two condensing sections. The inner spaces of the two condensing sections and the evaporating section are interconnected. The peripheral dimension of the evaporating section is larger than the peripheral dimension of each of the condensing sections. The mesh is contained in the step pipe and located inside the evaporating section. The supporting component is contained in the step pipe and wrapped in the mesh. The combination of these structures increases air's flow rate inside the heat pipe and improves the heat pipe's heat conduction efficiency.
