Description
- This application claims priority of Taiwan Patent Application No. 091114537, filed on Jul. 1, 2002.
- 1. Field of the Invention
- The invention relates to a heat-dissipating device, more particularly to a heat-dissipating device that can dissipate heat in a highly efficient manner.
- 2. Description of the Related Art
- FIG. 1 shows a conventional heat-dissipating device adapted to be mounted on top of a heat-
generating component 12 that is disposed on acircuit board 11 of an electronic device. The heat-generating component 12 can be a central processing unit, an integrated circuit, or the like. The heat-dissipating device includes an aluminum heat-dissipatingfin unit 13 disposed in thermal contact with the heat-generating component 12, and afan 14 oriented toward thefin unit 13. Thefin unit 13 has a bottom portion provided with a heat-conductingplate 15 that is formed from copper and that facilitates the transfer of heat generated by the heat-generatingcomponent 12 to thefin unit 13. However, such a conventional heat-dissipating device has the following setbacks: - 1. Although aluminum and copper have quite high temperature coefficients of conductivity, their combined heat-dissipating effect is not very satisfactory, resulting in that the surface temperature of the heat-generating
component 12 remains higher than that of thefin unit 13. That is, currents of air blown from thefan 14 can only disperse the heat around thefin unit 13, and cannot reach the surface of the heat-generatingcomponent 12 to dissipate the heat around the heat-generating component 12. - 2. In view of the aforesaid, when heat gradually accumulates on the surface of the heat-
generating component 12, since the conventional heat-dissipating device cannot effectively dissipate the high heat, the operation of the heat-generating component 12 will be affected, which may result in shutdown of or even damage to the electronic device. - 3. Referring to FIG. 2, where the heat-generating
component 12 is a central processing unit disposed within acomputer housing 2 and mounted in aprocessor socket 16 of amain board 17, the currents of air produced by thefan 14 for dissipating the heat around the central processing unit will become hot and disperse within thecomputer housing 2, thereby raising the temperature within thecomputer housing 2. Although a power supply 3 with an exhaust-type fan unit 31 is disposed for drawing the hot air from within thecomputer housing 2, as well as dissipating the heat generated thereby, the heat dissipating effect is not ideal. - Therefore, the main object of the present invention is to provide a heat-dissipating device which achieves an enhanced heat-dissipating effect using a single fan unit.
- Accordingly, a heat-dissipating device of this invention includes:
- a thermal superconducting body including a hollow heat transfer body adapted to be disposed on a heat-generating component of an electronic device, the heat transfer body being made of a heat-conducting material and being configured to confine at least one air channel;
- a fan unit disposed to draw hot air away from the heat transfer body; and
- a guide pipe having an inlet port in fluid communication with the heat transfer body for collecting hot air from the heat transfer body, an outlet port in fluid communication with the fan unit, and an intermediate pipe portion interconnecting the inlet and outlet ports for guiding the hot air from the inlet port to the outlet port for extraction by the fan unit.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
- FIG. 1 is a schematic exploded side view of a conventional heat-dissipating device;
- FIG. 2 is a fragmentary partly cut-away perspective view showing the conventional heat-dissipating device in a computer housing;
- FIG. 3 is a perspective view of a preferred embodiment of a heat-dissipating device according to the present invention in a state of use;
- FIG. 4 is a sectional view illustrating a thermal superconducting body of the preferred embodiment; and
- FIG. 5 is a top view of the thermal superconducting body of the preferred embodiment.
- Referring to FIGS.3 to 5, the preferred embodiment of a heat-dissipating device according to the present invention is shown to include a thermal
superconducting body 4, afan unit 7, and aguide pipe 6. - The thermal
superconducting body 4 includes a hollowheat transfer body 40 adapted to be disposed on a heat-generatingcomponent 5, such as a central processing unit, of an electronic device, and is made of a heat-conducting material, such as aluminum, copper metal, alloy metal, or other materials with good thermal conductivity. Theheat transfer body 40 has an inner surface confining a sealedvacuum chamber 41, and abase portion 45 adapted to be disposed in thermal contact with the heat-generating component 5 so that heat generated by the heat-generating component 5 is transferred to theheat transfer body 40. The thermalsuperconducting body 4 further includes aheat transfer layer 42 that is formed from a superconductor material and that forms a superconductor lining on the inner surface of theheat transfer body 40. In this embodiment, the superconductor material is injected into theheat transfer body 40, which is then evacuated and sealed to form the sealedvacuum chamber 41. It is noted that a plurality of equidistantly spaced-apart limiting blocks can be disposed on the inner surface of theheat transfer body 40 so as to prevent flattening or angular deformation of theheat transfer body 40 when air is exhausted from theheat transfer body 40 to form the sealedvacuum chamber 41. - It is noted herein that the superconductor material includes at least one compound selected from the group consisting of sodium peroxide, sodium oxide, beryllium oxide, manganese sesquioxide, aluminum dichromate, calcium dichromate, boron oxide, dichromate radical, and combinations thereof; at least one compound selected from the group consisting of cobaltous oxide, manganese sesquioxide, beryllium oxide, strontium chromate, strontium carbonate, rhodium oxide, cupric oxide, β-titanium, potassium dichromate, boron oxide, calcium dichromate, manganese dichromate, aluminum dichromate, dichromate radical, and combinations thereof; or at least one compound selected from the group consisting of denatured rhodium oxide, potassium dichromate, denatured radium oxide, sodium dichromate, silver dichromate, monocrystalline silicon, beryllium oxide, strontium chromate, boron oxide, sodium peroxide, β-titanium, a metal dichromate, and combinations thereof.
- In practice, prior to injection of the superconductor material into the
heat transfer body 40, the sealedvacuum chamber 41 is subjected to passivation and is then washed and dried. - In this embodiment, the
heat transfer body 40 is formed with a plurality offins 43 extending uprightly from thebase portion 45 opposite to the heat-generating component 5. An adjacent pair of thefins 43 defines anair channel 44. - The
fan unit 7 is disposed to draw hot air away from theheat transfer body 40. - The
guide pipe 6 is made from a heat-resistant metal or rubber material, and has aninlet port 61 in fluid communication with theheat transfer body 40 for collecting hot air from theheat transfer body 40, anoutlet port 63 connected to and in fluid communication with thefan unit 7, and a flexibleintermediate pipe portion 62 interconnecting the inlet andoutlet ports inlet port 61 to theoutlet port 63 for extraction by thefan unit 7. Theinlet port 61 of theguide pipe 6 is connected to thebase portion 45 of theheat transfer body 40, and has thefins 43 disposed therein so as to be in fluid communication with theair channels 44 defined by the fins 33. In this embodiment, theintermediate pipe portion 62 is configured as a bellows pipe portion. - In use, by virtue of the exceptionally high temperature coefficient of conductivity of the thermal
superconducting body 4, the heat generated by the heat-generatingcomponent 5 during operation thereof can be quickly transferred to the thermalsuperconducting body 4. In addition, as theinlet port 61 of theguide pipe 6 straddles over the thermalsuperconducting body 4, the hot air around the heat-generatingcomponent 5 can be directed to flow along theair channels 44 through theguide pipe 6 for extraction via thefan unit 7, thereby rapidly lowering the temperature around the heat-generating component 5. - It is noted that the
fan unit 7 can be a fan member of a power supply (not shown) disposed in a computer housing (not shown) for supplying electric power to a computer. As such, when the computer is powered on, thefan unit 7 can suck hot air around the heat-generatingcomponent 5 and other heat-generating components, such as hard disk drives, optical disk drives, via theinlet port 61 of theguide pipe 6 for extraction to the exterior of the computer housing. - For enhancing heat-dissipating effect, the heat-dissipating device of this invention further includes a
heat collecting plate 8 adapted to be disposed between the thermalsuperconducting body 4 and the heat-generating component 5. Theheat collecting plate 8 has two opposite surfaces, each of which is coated with aheat conducting paste 9. In this embodiment, theheat collecting plate 8 is formed from a metal material of good heat conductivity, such as copper and aluminum. - It has thus been shown that the heat-dissipating device of this invention can achieve an excellent heat-dissipating effect with the use of only a single fan unit.
- While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
