Abstract: A spiral heat exchanger includes two assembled covers defining a chamber therebetween for receiving a spiral unit therein. The spiral unit includes a first and a second spiral member separately spirally extending from a central outlet to a peripheral outlet on the two covers to respectively form a first and a second flow passage. A driving unit is assembled to and drives the assembled covers to rotate at the same time, so that cold and hot airflows respectively enter and flow through the first and second spiral members from the central outlet to the peripheral outlet under a centrifugal force to exchange heat at the spiral unit. The spiral unit provides extended flow passages and increased heat exchange area, giving the spiral heat exchanger increased heat transfer capacity and heat exchange efficiency and allowing omission of fans and radiating fin assembly to eliminate operating noise and accumulated dust.

Abstract: A heat exchanger includes a body having a center and a spiral guiding trough extending spirally and outwardly from the center toward an outside of the center. The radius of the spiral guiding trough increases gradually from the center toward the outside of the center. A first port and a second port are in communication with the spiral guiding trough respectively. With the combination of the spiral guiding trough and the body, the fluid can be sufficiently mixed in the spiral guiding trough, thereby achieving an excellent thermal-conducting effect.

Abstract: A heat pipe structure includes a pipe body and a convection device. The pipe body defines a chamber enclosed in an inner wall of the pipe body. The convection device includes a rotary unit and a driving unit for creating a fluid pressure gradient in the chamber of the pipe body. The rotary unit and the driving unit are respectively located at an interior and an exterior of the pipe body. When the driving unit is excited, the rotary unit is driven to rotate under magnetic induction. With the fluid pressure gradient created in the chamber of the pipe body, the circulation of the working fluid in the chamber can be improved, and a forced convection flow of the working fluid in the pipe body is enabled to largely increase the heat transfer efficiency and heat transfer effect of the heat pipe.

Abstract: A heat radiating unit is provided on a front face with at least one raised strip having a curved head portion and a neck portion, the neck portion being located at a joint of the raised strip and the heat radiating unit and having a width smaller than that of the curved head portion; and on a reverse face with at least one receiving groove opposite to the raised strip, the receiving groove having a curved recess portion and an engaging shoulder portion, and the engaging shoulder portion being located at a joint of the receiving groove and the heat radiating unit. A plurality of the heat radiating units can be assembled to provide a heat sink by engaging the curved head portion and the neck portion of one heat radiating unit with the curved recess portion and the engaging shoulder portion, respectively, of another heat radiating unit.

Abstract: A cover structure for the core of a heat exchanger is provided. The core of a heat exchanger includes a partition plate and a cover. The cover includes a plurality of frames, an upper cover body, and a lower cover body. The upper cover body and the lower cover body join and together define a receiving space for receiving the frames. The frames are disposed on two sides of one of the upper cover body and the lower cover body, allowing the receiving space to be formed between the frames. Each of the frames has a plurality of crosswise extending posts provided therein. Each of the crosswise extending posts extends from an edge thereof, wherein the edge of each of the crosswise extending posts adjoins the receiving space. The crosswise extending posts and the frames together define a plurality of slits. The crosswise extending posts of the frames are coupled to the partition plate directly.

Abstract: A water-cooling heat-dissipating module of an electronic apparatus includes a heat-conducting unit, a driving unit and a dissipating unit. The heat-conducting unit has a function of conducting a heat source. The dissipating unit has a function of dissipating the heat of a fluid. The driving unit has a function of driving the fluid. Via the driving unit, the fluid can be rapidly introduced into or drained out of each unit for circulation, thereby achieving the heat-dissipating effect.

Abstract: A structure for eliminating electromagnetic interference caused by CPU includes a fixing seat, onto which two conductive members having a plurality of elastic contacts are mounted. Each of the conductive members is formed at two ends with two contact wings that are in contact with contacts of a demagnetizing circuit provided on a circuit board onto which the fixing seat is assembled with fastening members. When a central processing unit mounted on the circuit board operates and generates electromagnetic waves, the same are received by a radiator mounted on the fixing seat in contact with the conductive members, and then guided by the conductive members from the radiator to the demagnetizing circuit and be eliminated.
