An airtight penetration structure for heat dissipation device includes a first plate member, a second plate member, and a plurality of hollow shaft members. The first and the second plate member are closed to each other to together define a closed chamber between them. The hollow shaft members are respectively provided at two free ends with a first and a second flange. The hollow shaft members are correspondingly extended through fastening holes provided on the first and the second plate member with the first and the second flanges attached to and flush with outer surfaces of the first and the second plate member to seal around the fastening holes, so that the closed chamber between the first and the second plate member is in an airtight state.
Abstract:
A heat insulation structure for hand-held device includes a holding body disposed in a hand-held device. The holding body has a frame and internally defines a receiving space, in which a holding section is provided. A heat insulation space is formed between the frame and the holding section. The frame and the holding section are connected to each other via at least one connecting member. With the heat insulation space formed between the frame and the holding section, the heat insulation structure for hand-held device provides effective heat dissipation effect to prevent a hand-held device from burning a user's hand due to heat produced by electronic elements in the had-held device.
Abstract:
The present invention relates to a protective structure of a stator and a fan using the same. The protective structure of a stator comprises plural silicon steel sheets, at least one first filler, and a cover body. The silicon steel sheets are surrounded by plural coils. Each of the silicon steel sheets has a hole and plural magnetic poles extending symmetrically outward from the hole. Each of two adjacent magnetic poles defines a space. The first filler is disposed in the spaces. The cover body is disposed to surround the silicon steel sheets such that the cover body, the silicon steel sheets, and the first filler are integrally combined. Therefore, by means of the first filler disposed in the spaces of each of two adjacent magnetic poles, the amount of cover body material can be effectively reduced to further achieve the effect of cost reduction.
Abstract:
The present invention relates to a water cooling device which comprises a liquid storing shell body having a liquid chamber and a pump having a stator and a rotor. The stator has a coil set disposed electrically on a circuit board. The circuit board and the coil set thereon are both disposed on at least one inner wall of the liquid chamber or integrally overmolded in the liquid storing shell body. The rotor and a propeller oppositely connected to the rotor are received in the liquid chamber and exposed in the cooling liquid. The propeller is provided with a plurality of blades made of metal. At least one magnetic pole region is magnetized on each of the blades opposite to the coil set. Therefore, a thinning effect can be achieved.
Abstract:
A method of removing ineffective portion of flat heat pipe is disclosed. The method includes the steps of providing a flat heat pipe; flattening out at least one wick-free flatten-out zone of the flat heat pipe and then sealing the flattened flatten-out zone by welding; and cutting off a cut-away section but reserving a remainder section of the flattened and sealed flatten-out zone, so that an ineffective portion is removed from the flat heat pipe. After being processed with the above method, the flat heat pipe can have effectively increased heat transfer efficiency and save a lot of space.
Abstract:
A heat dissipation structure for a wearable mobile device comprises a wearable mobile device and a flexible belt. The wearable mobile device has a receiving space which receives a plurality of electronic components having at least one heat source. The flexible belt is made of rubber or silicone and has a cavity which has at least one wick structure and a working liquid. A wall of the cavity protrudes to form a supporting portion. The flexible belt defines a heat absorbing portion and at least one heat dissipating portion. Two ends of the heat absorbing portion form the heat dissipating portion. The heat absorbing portion contacts the electronic components or the heat source to conduct heat. The present invention provides a heat dissipation structure using a vapor-liquid circulating chamber and structure disposed in a flexible belt for a wearable mobile device to enhance the whole heat dissipation efficiency.
Abstract:
An annular fan wiring structure includes a frame body and at least one groove annularly formed on an outer circumference of the frame body. The groove has an open end and a closed end opposite to the open end. The open end is flush with the outer circumference of the frame body. According to the structural design of the annular fan wiring structure, the wire assembly can be securely received in the groove to facilitate storage of the annular fan. In addition, multiple annular fans can be most compactly stacked to form an annular fan module. Also, the manufacturing cost of the annular fan is lowered.
