Abstract: The present invention provides a heat-radiating module with composite phase-change heat-radiating efficiency. The cooling pad of the heat-radiating module is fitted with a heating portion and radiating portion. The first and second chambers are placed at intervals into the cooling pad. The first and second phase-change materials are separately placed in two chambers. The reaction temperatures of two phase-change materials differ from each other. The phase-change material of higher reaction temperature assists in heat-absorbing and preventing overheating. There is a heat peak when the cooling pad reaches the preset high-temperature state. When the temperature of the cooling pad declines below a preset temperature, the phase-change material of lower reaction temperature will release the stored latent heat, enabling the cooling pad to maintain an operating temperature and improve the heat-radiating efficiency in a variety of equipment.

Abstract: The heat-radiating device with composite heat radiation efficiency includes a foundation with a heating surface and a radiating surface. The foundation has an inner space for inserting phase-changing materials. A heat pipe includes a heat-absorbing end placed into the foundation and a radiating end protruded out of the foundation. A radiating fin set is arranged onto the radiating end of the heat pipe. The heat-radiating device enables the heat absorbed by the foundation to be quickly guided out of the foundation through the heat pipe. The radiation area is increased by the radiating fin set for improved heat radiation efficiency. The phase-changing material assists in heat absorption and storage by latent heat, thereby avoiding overheating of foundation and also helping to control efficiently the heat peak of the foundation. Furthermore, the heat-radiating device has a composite heat radiation effect with improved applicability.

Abstract: The present invention provides a vane structure of an airflow generator. The plate of predefined thickness and width has a locating portion and a swinging end. The swinging end of the vane is wider than the locating portion. There is an oblique section placed between the swinging end and locating portion for linking purposes. A better wind guide effect can be obtained from the expanded swinging end, and the oblique section is employed to reduce inlet stagnation, thus greatly improving the smoothness of air flow and the operating performance of the vane with better applicability.

Abstract: The heat pipe structure includes a pipe body, hollow groove and capillary tissue. The pipe body contains a heat-conducting end and a radiating end. The capillary tissue of a predefined thickness is adapted to an inner wall of the pipe body. The inner surface of capillary tissue is located correspondingly to the section of the heat-conducting end, where a portion with greater thickness is shaped from another section of the capillary tissue. The portion is of single side, a plurality of sides or annular structure. Thus, the heat conduction efficiency of the heat-conducting end greatly improves. The non heat-conducting sections of the capillary tissue remain still with respect to thickness, and the guide space expands to facilitate guiding of gaseous working fluid to the radiating end, thus achieving an optimum heat radiation effect.

Abstract: The present invention provides a heat pipe structure of a heat radiator, which includes two vertically protruded radiating portions and heat-absorbing portions at a bottom of the two radiating portions. The heat-absorbing portions are assembled onto the heat-conducting pedestal. Two turning portions are formed at the intersection of the heat-absorbing portions and two radiating portions. The heat-absorbing portion has a curved shape. The heat-absorbing portions of adjacent heat pipes are misaligned, such that the turning portion of the heat-absorbing portion of one heat pipe aligns with the recessed space of the other heat pipe. A minimum of heat pipe assembly space obtains a maximum heating area, thus greatly improving the heat-radiating effect and reducing the manufacturing cost with better applicability and economic efficiency.

Two magnetic poles are assembled at predefined locations on the plate nearby the pivot point. The magnetic coil is located opposite to magnetic poles of the plate, then a controller is used to control the magnetization state of the magnetic coil, thus yielding suction and repulsion with magnetic pole and driving the swinging end of the plate. The volume of the generator of the present invention is minimized, but an efficient heat-radiating effect is achieved to resolve the bottleneck of a typical radiator fan, making it applicable to the heat-radiating structure of various small-sized electronic devices.

Abstract: The panel-type heat sink module combines the heat-conducting panel, fin heat sink, diversion tank, fan and heat pipe into a single module. There is a heat-conducting surface and an assembly surface of the heat-conducting panel. The fin heat sink is assembled onto the assembly surface. The diversion tank is adapted onto the assembly surface and located nearby the fin heat sink. The diversion tank includes a fan container and a diversion channel. The fan is assembled into the fan container, and the heat pipe is assembled between the assembly surface and the fin heat sink. The heat pipe penetrates through the diversion tank; thus, the heat sources guided by the heat-conducting panel will be uniformly guided into the fin heat sink and diversion tank via the heat pipe. An air stream generated by the fan flows towards the fin heat sink, improving heat-radiation, and reducing assembly space.

Abstract: The present invention provides an improved fan frame with a diversion structure. A cooling fan includes a rotor, and fan blades spaced around the rotor at intervals. The fan frame positions the rotor and defines a diversion loop, which corresponds to the air outlet direction when fan blades are turning and has an expanding diversion surface. The fan frame has a diversion surface with diversion ribs spaced at intervals, the placement of the diversion ribs being in a vortex pattern without passing through the hypothetical point of the rotor center. The airflow generated by turning fan blades is guided by the diversion ribs and converted to outlet airflow in axial direction corresponding to the rotor, effectively reducing impact and friction of the gyrate airflow generated by fan blades against the frame diversion surface, lowering the noise level, making air exhaustion smoother, and improving the cooling efficiency of fan.

Abstract: The present invention provides an improved structure of the magnetic shaft of a cooling fan. A magnetic attraction component is comprised of a magnetic ring, a magnetic inductive bottom board, and a magnetic inductive ring. The magnetic field generated by the magnetic ring is guided from the upper and lower side by the magnetic inductive ring and the magnetic inductive bottom board respectively, so that the range of magnetic field scattered by the magnetic ring is effectively and reliably guided and suppressed. The range of the magnetic field is reduced to the smallest possible, and interference with other components is minimized within the cooling fan, working stability and quality of the cooling fan being enhanced.

Abstract: The present invention provides a heat-pipe generator. The blade is assembled into the heat pipe, a magnetic rotor is arranged around the blade, and generating coils are assembled externally onto the heat pipe opposite to the magnetic rotor. When the working liquid within the heat pipe is evaporated into vapor to drive the blade and the magnetic rotor, the generating coil outside of the heat pipe will yield inductive power, thus maintaining a vacuum state in the heat pipe for heat conduction. The magnetic rotor and generating coils may generate power accordingly.

Then, the open end of heat pipe is welded by fusing within enclosed operating space, wherein the sealing end of heat conductor forms a welded close end. A compression procedure can be neglected, thereby saving more manufacturing cost and offering a higher structural strength for the sealing part.

Abstract: A gyrating device includes a stator and a rotor. The stator is formed of at least one induction member and two induction coils connected with the induction member by an induction signal. The rotor is formed of at least one magnet and two inductors. The rotor is caused to engage in a reciprocating motion by an attracting force and a repelling force, which are brought about between the magnet and the induction coils at the time when the induction coils are driven by a voltage. The action force and the reaction force of the reciprocating motion of the rotor can be changed at a speed by adjusting the voltage, thereby resulting in a vibrating motion of the rotor.
