Abstract: The present invention relates to a rapidly removable thermal connector including a retainer and a clamper. The retainer has a first wedge connected with a convexity of a first two-convexity tenon and a second wedge. At the outer end of the first wedge has a mortise to allocate a convexity of the first two-convexity tenon; at the inner end of the second wedge has a mortise to allocate a convexity of a second two-convexity tenon. The clamper is used to hold the retainer. At the interior of the outer end of the clamper has a movable unit which is connected to the clamper with a bolt at one end and has a vertical concavity at the other end to match the first convexity of the first two-convexity tenon. At the interior of the inner end of the clamper has a mortise which allocates the fourth convexity of the second two-convexity tenon. The third convexity of the second two-convexity tenon is connected to a mortise at the inner end of the second wedge.

Abstract: A liquid cooling method for cooling LED lights used for minimally invasive surgeries is provided. The LED lights are integrated with the micro camera so that only one pipeline is needed to accommodate the electrical wires and cooling liquid conduits. The electrical wires disposed in the electrical wire conduit provide the path for electrical power required by the micro camera and the LED lights as well as the electronic signals from the micro camera. The liquid conduits guide the circulating cooling liquid to pass by the bottom surface of the LED substrate and carry the generated heat off the human body.

Abstract: A heat dissipation structure of an electronic apparatus includes a bendable vapor chamber with a large area. A small section of the vapor chamber is arranged to contact with the heat source of the electronic apparatus and a large remaining section of the vapor chamber contacts with an internal wall of the chassis of the electronic apparatus through appropriate bending. The working fluid in the vapor chamber absorbs the heat generated by the heat source and vaporizes. The heat-carrying vapor spreads within the vapor chamber to condense on a large condensation zone. The released heat is then dissipated to the atmosphere via the large area of the chassis and the heat dissipating fin structure thereon. Therefore, the heat dissipation structure provides efficient passive heat dissipation.

Abstract: An LED lamp includes at least a flat-plate heat pipe arranged within a flat sealing container, wherein the upper and the lower surfaces of the flat-plate heat pipe respectively contact with the internal walls of the top plate and the base plate of the sealing container. At least one LED module is configured on the base plate. The heat generated by the LED module transfers through the base plate to the flat-plate heat pipe, and vaporizes the working fluid therein, so that the heat is spread with the vapor motion, and is then released to the atmosphere through the large area including the external wall of the sealing container and the fin structure thereon. The sealing container provides structural strength of the lamp and protects the flat-plate heat pipe from corrosion by water and contaminants in the environment.

Abstract: A replaceable water-cooling module for LED headlamp includes a water-cooling head located outside an open hole of a housing and an LED light module with its substrate mounted over the open hole against the inner wall of the housing, using a set of detachable mounting elements through a plurality of mounting holes around the open hole. The water-cooling head is mounted against the substrate of the LED light module, using another set of detachable mounting elements. The bottom surface of the LED substrate directly contacts with the base surface of the water-cooling head through the open hole. The heat generated by the LED lights, through the LED substrate, effectively transmits to the water cooling head.

Abstract: Heat dissipation devices for an LED lamp set has a plate-type heat spreader as the core unit. The plate-type heat spreader is either a flat-plate heat pipe or a metal plate embedded with heat pipes. The high-power LED lamps are thermally connected to the bottom surface of the heat spreader so that the heat generated by the LED lamps is absorbed by the evaporation region of the flat-plate heat pipe or the embedding heat pipes. The heat is spread by internal vapor motion of the working fluid toward different regions of the heat spreader. The top surface of the heat spreader is connected with a finned heat sink, where the heat is delivered to the ambient air. The hot air leaves by buoyancy through the openings on a lamp housing located above the finned heat sink. The inner surface of the lamp housing can be connected with the top surface of the plate-type heat spreader, with the heat dissipated out at the surface of the housing by natural convection.

Abstract: Heat from a heat generating device such as a CPU is dissipated by a heat spreader containing a cycled two-phase vaporizable coolant. The coolant cycles inside a closed metal chamber, which has an upper section and a lower section. The lower section contains a wick layer, a part or parts of which serves as an evaporator. The upper section is composed of a set of channels. The channel walls contain a plurality of cut-off openings over the evaporator region to allow for vapor distribution efficiently. The liquid coolant in the evaporator is vaporized by the heat from the heat generating device. The coolant vapor can prevail in the channels by either directly entering the adjacent channels or indirectly through lateral conduits formed with the wall openings. The vapor condenses on the channel, walls to liberate latent heat which is then dissipated out through the top chamber wall.

Abstract: Heat from a heat generating device such as a CPU is dissipated by a heat sink device containing a recycled two-phase vaporizable coolant. The coolant recycles inside a closed metal chamber, which has an upper section and a lower section connected by a conveying conduit, and a wick evaporator placed in the lower section. The liquid coolant in the evaporator is vaporized by the heat from the heat generating device. The coolant vapor enters the upper section and condenses therein, with the liberated latent heat dissipated out through the inner top chamber wall. The condensed coolant is then collected and flows into the lower section, and further flows back to the wick evaporator by capillary action of the evaporator, thereby recycling the coolant. Space or a piece of element with parallel grooves is used to form at least one of the sections to reduce friction in the liquid flow path.

Abstract: This invention discloses a cold-work method to connect the metal wall of a two-phase heat dissipation device with a fill tube. First, place the fill tube into a hole prepared in the wall, then push a squeezer slightly larger than the inner diameter of the fill tube to create permanent deformation and hence hermetical bonding thereof. Finally, draw out the squeezer to finish the cold work. This method simplifies the procedure and equipment by avoiding a relatively high-temperature soldering or brazing process.
