The first heat dissipation module has a heat absorbing surface in thermal contact with a first heat source. The second heat dissipation module has a heat absorbing surface in thermal contact with a second heat source. The first heat dissipation module is disposed on the bridge heat pipe. The second heat dissipation module is pivoted to the bridge heat pipe for adjusting an angle between the heat absorbing surface of the first heat dissipation module and the heat absorbing surface of the second heat dissipation module.

Abstract: A thermoelectric cooling module includes a base, a thermoelectric cooler and a plurality of heat exchangers. The base includes a case and a cover. The case has an inlet and an outlet. The cover covers the case. The cover and the case together define an accommodation space. The inlet and the outlet are connected with the accommodation space for a heat transfer fluid to flow in and out of the accommodation space. The thermoelectric cooler is in thermal contact with the cover for exchanging heat with the cover. The heat exchangers are disposed on and in thermal contact with the cover. The heat exchangers extend from the cover into the accommodation space for exchanging heat with the heat transfer fluid in the accommodation space.

Abstract: A facial tissue box holder for automobile includes two supports comprising a rectangular main section having slits at both ends, a rectangular side section hingedly secured to the main section, an engagement section pivotably secured to the side section, and a magnetic strip on inner surfaces of the engagement and side sections; and two straps comprising two hook and loop fasteners at both ends. The engagement sections can be inserted into sides of a tissue box. For each support pivoting the side section to magnetically secure to the engagement section, pivoting the main section to engage the back of the tissue box, looping one end of the strap around a post, securing one hook and loop fastener around the post, inserting the other end of the strap through the slits, and securing the hooks to the loops of the other hook and loop fastener will hang the tissue box.

Abstract: A stopping structure of a fan is described. An opening is opened on a surface of a frame, and a bearing support is disposed within the frame. A blade wheel is accommodated within the frame and pivoted to the bearing support. Then, a stopper is disposed at the frame corresponding to the opening, such that a distance between the stopper and the blade wheel is smaller than a distance between blades of the blade wheel and the frame. When the blade wheel moves outwards relative to the bearing support, the blade wheel is stopped by the stopper to prevent the blades from interfering with the frame, and a reactive force is generated at an axial center position of the blade wheel, so that an axle of the blade wheel is maintained on the same central axis as the bearing support when the axle restores an original position thereof.

Abstract: A fastening member for fastening a peripheral device in an electronic device casing and performing heat exchange with the peripheral device is presented. The fastening member includes a supporting plate and a pair of side plates. This pair of side plates is respectively disposed on two sides of the supporting plate to support the peripheral device. The side plates can be fastened to the electronic device casing. The supporting plate has a plurality of heat-conductive connecting pieces in contact with the casing for transferring heat generated by the peripheral device to the electronic device casing, so as to perform heat exchange.

Abstract: An air guiding structure includes a plurality of fins capable of swinging, an actuation member connected to each fin, and a memory deformable element connected to the outermost fin. When the memory deformable element is at a normal temperature, the fins remain at a normal angle; when deforming because of heat, the memory deformable element pulls the fins to swing. Further, the actuation member drives each fin to rotate to a working angle, and thus the air exhaustion direction is changed according to the temperature effect.

Abstract: An electronic device structure includes a first member and a second member. The two members are pivotally connected to each other by one end in a rotatable way. A distance between one side of the first member adjacent to a pivot and the pivot is larger than a distance between a bottom surface of the second member and the pivot. When the first member rotates relative to the second member to an operation position, the side of the first member adjacent to the pivot has an outer edge leaning against a plane, such that the second member is placed on the plane with an inclined angle, and an airflow space is formed to assist thermal dissipation.

Abstract: A heat dissipating device includes a heat-dissipating fin unit having a base plate with a lower surface disposed in heat-conductive contact with a heat-generating source, and a plurality of fin plates formed integrally on and extending upwardly from an upper surface of the base plate. Adjacent ones of the fin plates are spaced apart from each other so as to form an air guide groove therebetween. A fan unit, which is disposed on top of the fin unit, has a fan blade disposed in a fan housing, and an air guide member extending integrally from the fan housing toward the fin unit so as to confine an air guide region between the fan housing and the fin unit such that air flow generated by the fan blade can be guided to flow toward the fin unit via the air guide region.
