Abstract:
A supporting structure for vapor chamber includes a first and a second plate member, a supporting member, and a working fluid. The first and the second plate member together define a chamber between them. The supporting member is located in the chamber, and has at least one base portion and a plurality of supporting portions, such that a plurality of passages is formed on the supporting member. The working fluid is filled in the chamber to flow through the passages. With these arrangements, the supporting structure for vapor chamber can overcome the problems of deformation caused by thermal expansion or pressure and uncontrollable bottom flatness as found in the prior art and can be manufactured at reduced labor and time cost while provides upgraded heat transfer efficiency.
Abstract:
A heat sink fastening device includes an operating member and a retaining member axially extended through the operating member and associated with the latter via a pivot shaft. The operating member includes a cylindrical cam portion, which has an elastic element received therein to provide the cam portion with an elastic force. The cam portion has an upper end formed into a pair of cam surfaces, on which the pivot shaft is rested. The operating member can be horizontally rotated about an axis thereof. When the operating member is rotated, the cam surfaces rotate and cause the pivot shaft to move from a higher to a lower position on the cam surfaces or vice versa, so that the retaining member associated with the operating member via the pivot shaft is brought by the pivot shaft to axially move downward to a released position or upward to a fastened position.
Abstract:
A heat sink structure and a manufacturing method thereof. The heat sink includes a main body and multiple radiating fins each having a folded root section. The main body has multiple connection channels formed on a circumference of the main body. The multiple radiating fins are placed in a mold. A mechanical processing measure is used to high-speed impact the main body so as to thrust the main body into the mold. Accordingly, the folded root sections of the radiating fins are relatively high-speed thrust into the connection channels of the main body to tightly integrally connect with the main body.
Abstract:
A fastening structure is provided for fastening a thermal module to a mainboard, and includes a main body having at least one elastic press portion, a fastening portion, and an insertion unit. The fastening portion is provided on an end of the main body and the insertion unit is outward extended from another opposite end of the main body. The elastic press portion is provided on the main body and located between the insertion unit and the fastening portion, and a flexible space is defined between the elastic press portion and the main body. With these arrangements, the fastening structure can be quickly assembled to the thermal module without the need of welding and can therefore be conveniently separated therefrom whenever reworking is necessary.
Abstract:
A thermal module structure includes an aluminum base having a heat pipe receiving groove formed on one side thereof; a heat dissipation unit including a plurality of radiation fin assemblies or heat sinks and being provided with a first heat pipe receiving section; a plurality of heat pipes made of a copper material and respectively having a heat absorption section and a horizontally extended condensation section; and a copper embedding layer provided on surfaces of the heat pipe receiving groove and the first heat pipe receiving section. The aluminum base and the heat dissipation unit are horizontally parallelly arranged. The heat absorption sections are fitted in the heat pipe receiving groove, and the condensation sections are extended through the first heat pipe receiving section. With the copper embedding layer, the aluminum base and the heat dissipation unit can be directly welded to the heat pipes.
Abstract:
A screw locking unit structure includes a screw main body having a head portion, a stem portion extended from a lower side of the head portion, a first screw locking section located below the stem portion, and a second screw locking section located below the first screw locking section; and an elastic element being externally fitted around the stem portion. The first screw locking section and the second screw locking section are externally provided with a first and a second male thread, respectively. The first and the second male thread are structurally different from one another to not only enable the screw main body to be temporarily held to an assembling interface before the latter is screw locked in place later, but also provide a function of stopping screwing automatically to prevent the second locking section extended through the assembling interface from being excessively screwed into a heat source.
Abstract:
A thermal module includes a radiating fin unit having a plurality of superposed radiating fin assemblies, and a plurality of groups of heat pipes. The heat pipes respectively have a heat absorbing section and a heat dissipating section formed at two opposite ends thereof. The heat absorbing sections in each heat pipe group is in contact with a heat source, and the heat dissipating sections in the same heat pipe group is sandwiched between two adjacent ones of the radiating fin assemblies. The thermal module is characterized in that the heat dissipating sections are horizontally extended through the radiating fin assemblies from one of two opposite shorter sides to another shorter side along two parallel longer sides thereof, such that the heat dissipating sections not only have a maximum contact area with the radiating fin assemblies, but also give the radiating fin unit an enhanced structural strength.
Abstract:
A heat transfer member reinforcement structure includes a main body. The main body has a first side, a second side and a reinforcement member. The reinforcement member is selectively disposed between the first and second sides or inlaid in a sink formed on the first side. The reinforcement member is connected with the main body to enhance the structural strength of the main body.
Abstract:
A thermal module structure includes an aluminum base having an upper and a lower surface, at least one L-shaped copper heat pipe, a first aluminum fin assembly, a second aluminum fin assembly, and at least one copper embedding layer. The copper heat pipe includes a heat absorption section fitted on the aluminum base, and a heat dissipation section connected to the second aluminum fin assembly. The copper embedding layers are provided on the aluminum base at areas corresponding to the first aluminum fin assembly and the heat absorption section of the copper heat pipe, and on a bottom surface of the first aluminum fin assembly that is to be connected to the aluminum base. Thus, the first aluminum fin assembly and the copper heat pipe can be directly welded to the aluminum base via the copper embedding layers without the need of electroless nickel plating.
