Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a phase-change turbo-dissipation cooler that can dissipate heat generated from a heat source in an effective way.

DESCRIPTION OF THE PRIOR ART

With the increasingly sophisticated development of semiconductor technology, the heat generated by the CPU or the chipset of a computer is increasingly rising. To ensure an excellent performance of a computer and protect the components from being burned out, the heat generated in the computer must be dissipated efficiently. Thus, it is required for a computer to install an effective cooling device for dissipating the heat from the computer effectively. Besides, the recently developed LED lighting devices also have the problems of heat dissipation to be solved.
FIG. 1 shows a conventional cooling device for removing the heat generated from a heat source (C) such as a CUP or a chipset. The conventional cooling device comprises a heat sink (A), having a base plate (A1) and a plurality of fins (A2), and a fan (B). The underside of the base plate (A1) is spread with thermal paste and placed on the top surface of the heat source (C). The fan (B) is placed above the fins (A2) of the heat sink (A) and connected with a power supply (not shown). The fan (B) is electrically operated for the heat source (C). The base plate (A1) can redistribute the heat generated from the heat source (C). The fan (B) can send forth air through the fins to take away the heat redistributed to the fins (A2). The conventional cooling device mentioned above is a design by means of air convection. Although it can dissipate heat, it needs an external power supply and thus cannot meet the demands of green energy and carbon reduction.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a phase-change turbo-dissipation cooler that can dissipate heat effectively without external electrical power so as to meet the environmental protection requirements of carbon reduction and energy conservation.
The primary feature of the present invention resides in creating an heat extraction and dissipation system, wherein a liquid of low boiling point is vaporized in a closed container to become a dynamic vapor that can push the turbine wheel to rotate together with a blower wheel that can suck in ambient air to blow through a plurality of fins attached on a condensing tube. After pushing the turbine wheel, the cooled vapor flows through an expansion value and an inlet to enter the closed container so that a more effective phase-change cooling system can be built.
The technical means of the present invention comprises a heat extracting apparatus and a heat dissipating apparatus. The heat extracting apparatus is composed of a closed container having an outlet nozzle and an inlet, the closed container being filled with a liquid of low boiling point. The heat dissipating apparatus is composed of a chambered body, an air supply tube, a vapor tube, and a condensing tube. The chambered body is provided with a shaft wheel assembly therein, the shaft wheel assembly including a common shaft, a turbine wheel, and a blower wheel, the turbine wheel and the blower wheel mounted on two ends of the common shaft. The chambered boy is provided with an air intake and communicated with the outlet nozzle, the vapor tube, and the air supply tube, the condensing tube having one end communicated with the vapor tube and the other end communicated with the inlet of the closed container, and being provided with a plurality of fins and an expansion valve. The liquid of low boiling point can be vaporized to become a vapor in the closed container by a heat source contacting therewith. The vapor blows into the chambered body to rotate the turbine wheel and then flow back to the closed container by way of the vapor tube and the condensing tube, the blower wheel being rotated simultaneously via the common shaft between the turbine wheel and the blower wheel so that ambient air can be sucked in from the air intake to blow through the fins via the supply tube so as to dissipate heat.
A partition wall can be disposed within the chambered body to divide the chambered body into a first zone and a second zone, wherein the common shaft extends between the first zone and the second zone, the turbine wheel and the blower wheel are respectively located in the first zone and the second zone, the outlet nozzle is communicated with the first zone, the air intact and the air supply tube is communicated with the second zone.
The present invention can be applied in CPUs or chipsets of computers, LED lighting devices, or other equipments of heat source for dissipating heat.
Incidentally, the turbine wheel of the present invention can be used to drive a small generator, pump, fan or other devices to generate power, draw water, agitate air, and so on.
The present invention, which dissipates heat by means of a liquid of low boiling point without external electrical power, is indeed an environment-friendly design and can meet the environmental requirements of carbon reduction. It is believed that the present invention contains novelty and inventiveness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To enable those skilled in the art to implement the present invention, a detailed description will proceed in the following paragraphs with the accompanying drawings and numerals.
FIG. 2 is a schematic view showing an exemplary application of the present invention, in which a phase-change turbo-dissipation cooler according to the present invention is placed on a heat source 3, such as a CPU or chipset of a computer, for dissipating heat. The phase-change turbo-dissipation cooler generally comprises a heat extracting apparatus 1 and a heat dissipating apparatus 2. The heat extracting apparatus 1 is composed of a closed container 11 having an outlet nozzle 12 and an inlet 13. The closed container 11 is filled with a liquid 5 of low boiling point, such as acetone, carbon disulfide, methylene dichloride, cyclohexane, pentane, ethyl ether, or other chemical liquids. The liquid 5 of low boiling point is vaporized to become a vapor 51 by the heat redistributed from the heat source 3. The outlet nozzle 12 has a relatively small dimension such that the vapor 51 can flow out of the outlet nozzle 12 having a higher velocity.
The heat dissipating apparatus 2 is composed of a chambered body 21, an air supply tube 25, a vapor tube 26, and a condensing tube 27. The chambered body 21 is divided into a first zone 211 and a second zone 212 with a partition wall 22, the first zone 211 being isolated from the second zone 212. A turbine wheel 23 is located in the first zone 211. A blower wheel 24 is located in the second zone 212. A common shaft extends between the first zone 211 and the second zone 212. The turbine wheel 23 and the blower wheel 24 are mounted on two ends of the common shaft so that the turbine wheel 23 can integrally rotated bout the common shaft with the blower wheel 24. The output nozzle 12 and the vapor tube 26 are connected to the chambered body 21 respectively at two opposing sides of the turbine wheel 23, in which the output nozzle 12 and the vapor tube 26 are communicated with the first zone 211. An air intact 210 is formed with the chambered body 21 facing to the blower wheel 24. The air supply tube 25 is connected to the chambered body 21 substantially perpendicular to the air intact 210, in which the air intact 210 and the air supply tube 25 are communicated with the second zone 212. The condensing tube 27 is formed with multiple loops at one end thereof and connected to the inlet 13 at the other end thereof A plurality of fins 28 are attached to the condensing tube 27 at the portion of multiple loops. An expansion valve 29 is provided between the portion of multiple loops and the inlet 13. The fins 28 are located corresponding to the outlet of the air supply tube 25.
In operation, the present invention can be applied to a CPU 3 of a computer for heat dissipation. The undersurface of the closed container 11 is spread with thermal paste 4 and then attached to the CPU 3. The heat generated form the CPU 3 can be redistributed to the liquid 5 of low boiling point contained in the closed container 11 to have the liquid 5 vaporized to become a vapor 51, which can blow into the first zone 211 of the chambered body 21 through the outlet nozzle 12 so as to drive the turbine wheel 23 to rotate together with the blower wheel 24, which can suck in ambient air from the air intact 210 and discharge the air to blow through the fins 28 via the air supply tube 25. After driving the turbine wheel 23 to rotate, the vapor 51 can flow into the condensing tube 27, where the heat can be removed through the fins 28 being blown by the air supplied from the air supply tube 25. Thus, the vapor 51 can be cooled down and condensed in the condensing tube 27 to flow through the expansion valve 29 and the inlet 13 so as to enter the closed container 11.
Since the present invention can dissipate heat without external electrical power, it meets the demands of carbon reduction and energy conservation at the present time.
FIG. 3 shows another exemplary application of the present invention, in which the closed container 11 is placed to extract the heat generated from LEDs 62 of a lighting device 6. A layer of thermal paste 4 is spread between the closed container 11 and a base plate 61 of the lighting device 6. The process of heat extraction and dissipation has been described in detail in the above application. Thus, a detailed description for this application is omitted here.
Incidentally, the turbine wheel of the present invention can be used to drive a small generator pump, fan or other devices to generate power, draw water, agitate air, and so on.
Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention hereinafter claimed.
