Abstract: A straight-through structure of heat dissipation unit includes a first plate body and a second plate body correspondingly mated with each other to define a closed chamber. A hydrophilic layer is disposed on the surface of the closed chamber and a capillary structure is disposed in the closed chamber. The first plate body is formed with a first recess, a first perforation and a second recess. The first recess is connected with the capillary structure disposed on the third face of the second plate body. One end of the second recess abuts against the capillary structure. The capillary structure layer is not in contact with the first recess. The second plate body has a second perforation in alignment with the first perforation. When it is necessary to perforate the heat dissipation unit, the straight-through structure can keep the closed chamber in the vacuumed and airtight state.

Abstract: A heat pipe structure includes a main body. The main body has a first board body, a second board body, a capillary structure and a working fluid. The first and second board bodies are overlapped and mated with each other to hold the capillary structure. The capillary structure is formed with at least one passage. One of the first and second board bodies is formed with a protrusion section protruding toward the capillary structure. The protrusion section is attached to the capillary structure in adjacency to the passage. Accordingly, the heat pipe structure has an extremely thin thickness.

Abstract: A vapor chamber structure includes a main body, a fan and perforations. The main body has a heat absorption section, a heat dissipation section and a chamber. The heat absorption section and the heat dissipation section are respectively horizontally disposed on left and right sides of the main body. The heat absorption section is attached to at least one heat source. The chamber is positioned at the heat absorption section and partially extends to the heat dissipation section. The chamber has a capillary structure and at least one perforated section. The perforated section is connected between an upper side and a lower side of the chamber. The fan is disposed on one side of the heat dissipation section. The perforations are formed through the parts of the main body, which parts are free from the chamber and the parts of the main body, where the perforated section is disposed.

Abstract: A flat-plate heat pipe structure includes a main body. The main body has a first board body, a second board body, a first capillary structure and a working fluid. The first and second board bodies are overlapped and mated with each other. The first capillary structure is disposed between the first and second board bodies. The first capillary structure and the first and second board bodies together define at least one vapor passage. Accordingly, when the flat-plate heat pipe is thinned, the flat-plate heat pipe still keeps having a vapor passage, whereby the vapor-liquid circulation efficiency of the flat-plate heat pipe will not be deteriorated due to thinning.

Abstract: A heat dissipation structure for hand-held mobile device includes a supporting body having a first and an opposite second side and including at least one heat dissipation area. In the heat dissipation area, a heat dissipation element is correspondingly fitted without increasing an overall thickness and volume of the supporting body for the hand-held mobile device. With the heat dissipation element fitted in the heat dissipation area on the supporting body, heat produced by the hand-held mobile device during operation thereof can be quickly transferred to the heat dissipation element for dissipating into ambient air.

Abstract: A heat dissipation structure includes a heat conduction support body disposed in a handheld electronic device. The heat conduction support body has a first face and a second face opposite to the first face. A chamber is defined between the first and second faces. More than one capillary structure and a working fluid are disposed in the chamber. One of the first and second faces or both of the first and second faces are in contact with the electronic components of the handheld electronic device. One of the first and second faces is in contact with the housing of the handheld electronic device. Accordingly, the heat generated by the electronic components can be quickly conducted and dissipated outward.

Abstract: A heat dissipation structure of mobile device includes a case and a heat generation component. The case defines a receiving space. The heat generation component is disposed in the receiving space. One face of the heat generation component is attached to one face of a cooling chip. The other face of the cooling chip is attached to the case. The cooling chip serves to absorb the heat generated by the heat generation component and conduct the heat to the case to dissipate the heat, whereby the heat dissipation problem of the mobile device is solved and an energy-saving effect is achieved.
