20090151909 | Heat-Dissipating Unit - A heat-dissipating unit is provided. The heat-dissipating unit includes a board. The board is thermally conductive and includes a contact portion planar in shape. The contact portion is in immediate contact with a heat-generating source for the sake of heat transfer. An integrally formed branch portion extends outward from at least one end of the contact portion. With the contact portion being in immediate contact with the heat-generating source, heat is transferred from the heat-generating source to a remote end via the branch portion, thereby enhancing heat dissipation. | 06-18-2009 |
20090151922 | Heat pipe and method for forming the same - A heat pipe and a method for forming the same are provided. The method includes: defining a closed end, a closed portion, and a contact section in sequence along a heat pipe to be processed; closing the opening of the closed end and the passage of the closed portion so as to finalize the heat pipe; and cutting axially the contact section into a plurality of equal parts, bending the equal parts outward to assume a divergent shape, thereby providing the contact section with an area for contact with a heat-generating source. Heat is directly transferred from the heat-generating source to the heat pipe via the contact section, thereby enhancing heat dissipation. | 06-18-2009 |
20110088873 | SUPPORT STRUCTURE FOR FLAT-PLATE HEAT PIPE - A support structure for flat-plate heat pipe, including a main body and a fitting body. The fitting body has at least one open side and a first side section connected with the open side. The first side section has a capillary structure formed on a periphery of the first side section. The first side section and the open side together define a space for fixedly fitting the main body therein. By means of the capillary structure of the first side section of the fitting body, the circulating rate of a working fluid flowing within the flat-plate heat pipe is increased to achieve better heat dissipation effect and better thermal uniformity. | 04-21-2011 |
20110171055 | METHOD OF MANUFACTURING HEAT SINK PLATE - A heat sink manufacturing method includes the steps of positioning a heat conductive sheet on a lower half holding tool of a powder feeder; tightly closing and connecting an upper half holding tool of the power feeder to the lower half holding tool, such that spacers downward extended from the upper half holding tool are in tight contact with the heat conductive sheet; dispensing metal powder on the heat conductive sheet via a powder inlet on the upper half holding tool and under a positive pressure while vibrating the heat conducting sheet for the metal powder to uniformly distribute on the heat conductive sheet; opening the upper half holding tool and spraying an organic liquid on the metal powder for the same to set; and removing the heat conductive sheet from the lower half holding tool and sintering the metal powder to the heat conductive sheet. | 07-14-2011 |
20110259554 | FLAT PLATE HEAT PIPE AND METHOD FOR MANUFACTURING THE SAME - The present invention relates to a flat plate heat pipe and a method for manufacturing the same. The heat pipe includes a flattened pipe whose inner surface is coated with a wick structure layer. The interior of the flattened pipe is provided with a sintered supporting layer and a working fluid. The sintered supporting layer has a plurality of posts arranged in the flattened pipe to vertically support therein. With this arrangement, the thickness of the pipe can be reduced but the whole structural strength can be maintained to prevent deformation. Further, a return path for the working fluid can be provided in the pipe. By only sealing two sides of the pipe, a sealed chamber can be formed for the operation of the working fluid. By the inventive method, the manufacturing process can be simplified and a larger space inside the chamber can be obtained. | 10-27-2011 |
20110259555 | MICRO VAPOR CHAMBER - A micro vapor chamber includes: a first plate body having a first side and a second side, the second side having at least one condensation section; a second plate body having a third side and a fourth side, the third side being provided with at least one evaporation section and multiple flow collection sections, the third side being correspondingly mated with the second side of the first plate body, the fourth side contacting with at least one heat source; and a mesh structure body disposed between the first plate body and the second plate body. The mesh structure body is a capillary structure having multiple meshes and a first face and a second face. The first and second faces of the mesh structure body are mated with the condensation section and the evaporation section and the flow collection sections respectively to together define multiple flow ways. | 10-27-2011 |
20110314674 | METHOD FOR MANUFACTURING FLAT PLATE HEAT PIPE - The present invention relates to a method for manufacturing a flat plate heat pipe, which includes steps of: forming a wick structure layer and at least one wick structure post on the inner surface of a chamber of a pipe, pressing the pipe to become a flattened pipe with the wick structure post being connected therein, connecting a conduit to the chamber, sealing both sides of the flattened pipe, evacuating air inside the chamber through the conduit, filling a working fluid into the chamber, and sealing the conduit. According to this method, a flat plate heat pipe can be made in a simplified manner with increased yield and reduced cost. | 12-29-2011 |
20120131798 | HEAT PIPE AND METHOD FOR FORMING THE SAME - A heat pipe and a method for forming the same are provided. The method includes: defining a closed end, a closed portion, and a contact section in sequence along a heat pipe to be processed; closing the opening of the closed end and the passage of the closed portion so as to finalize the heat pipe; and cutting axially the contact section into a plurality of equal parts, bending the equal parts outward to assume a divergent shape, thereby providing the contact section with an area for contact with a heat-generating source. Heat is directly transferred from the heat-generating source to the heat pipe via the contact section, thereby enhancing heat dissipation. | 05-31-2012 |
