Abstract: A heat sink includes a plurality of heat dissipation fins. Each of the heat dissipation fins includes a sheet body, at least one bent part, and at least one first combined part. The bent part is formed from a terminal end of the sheet body. The first combined part protrudes from the bent part along a direction opposite to the bent direction of the bent part. A manufacturing method of the heat sink is also disclosed.

Abstract: The invention discloses a heat dissipation module. The heat dissipation module includes two separate cases and a porous structure. The cases are U-shaped and correspondingly connect to each other to form a sealed chamber. The porous structure is formed on an inner surface of the chamber. The heat dissipation module further includes at least one heat conducting structure connected to an exterior surface of the sealed chamber. The heat conducting structure may be fins or heat conducting plates connected to the chamber by welding, locking, fitting, engaging, or adhering.

Abstract: A heat dissipation module is disclosed for providing good heat-dissipating efficiency. First and second cases correspond to each other, with a heat conducting structure connecting to an opening of the second case. The first and second cases and the heat conducting structure form a closed structure with a porous structure therein.

Abstract: A heat dissipation structure made of a heat-conductive material, comprising at least one penetration portion which penetrates therethrough. The at least one penetration portion further comprises a solid portion which is located at the center of the at least one penetration portion and provided with a penetration hole penetrating therethrough, and at least one bridge portion which surrounds the solid portion and is connected between the solid portion and the body of the heat dissipation structure.

Abstract: The circulative cooling apparatus has a first chamber, a second chamber, a first pipe, and a second pipe. There are porous structures on internal walls of the first chamber and the second pipe. There is work fluid in the second chamber and the porous structures. The work fluid is evaporated by heat in the first chamber, and owing to the pressure drop the vapor of the work fluid moves to the second chamber through the first pipe. Then the vapor of the work fluid condenses into the work fluid in the second chamber. Afterward the work fluid is transported back to the first chamber through the second pipe using the porous structures thereof, thus forming a circulative cooling apparatus.

Abstract: A cooling fin structure is constructed by a thermally conductive sheet bent to form a heat radiation part and a welding part. The welding part is formed with a vacant region, which is defined by notches, openings or a slot, and the thermally conductive sheet is welded to a substrate through the welding part.

Abstract: A fin structure is disclosed. The fin structure includes a first concavo-convex portion formed with a concave on a first surface of the fin in the direction of thickness and a corresponding convex on a second surface of the fin in the direction of thickness. Besides, a second concavo-convex portion formed with a first concave and second concave on the first surface of the fin in the direction of thickness and a corresponding first convex and a corresponding second convex on the second surface of the fin in the direction of thickness is included as well. Specifically, the first and second concavo-convex portions are symmetrical respect to the center of the fin. Furthermore, the second convex of the second concavo-convex portion on one fin can be exactly received by the concave of the first concavo-convex portion on another fin.
