Multi-directional cooling structure for interface card

A multi-directional cooling structure for an interface card includes: a first cooling plate, configured on the interface card; a second cooling plate, configured at one side of the first cooling plate; at least one heat conduction element, configured on the first cooling plate and second cooling plate, and including a first heat conduction portion positioned on the first cooling plate and a second heat conduction portion in connection with the first heat conduction portion and positioned on the second cooling plate; and at least one cooling fin set, configured on one side of the heat conduction element away from the first and second cooling plates, and in direct contact with the heat conduction element. Therefore, the heat can be conducted not only to one side through the heat conduction element but to the cooling fin sets above, advantageously achieving multi-directional heat dissipation.

(a) TECHNICAL FIELD OF THE INVENTION

The present invention relates to a cooling structure for an interface card, and more particularly to a multi-directional cooling structure for an interface card, which has a very good cooling effect.

(b) DESCRIPTION OF THE PRIOR ART

Personal computers are developed fast; users not only require computer processing speed, but also pay more attention to the stability of the computer. Because semiconductor integrated circuit technologies are progressed significantly and micrometer, nanometer technologies have breakthrough, the number of semiconductors in one chip is increased from original dozens up to the current tens of millions. Although the technical progress allows personal computers to be much cheaper and the performance of electronic components to be improved significantly, cooling capacity is often unable to go hand in hand with the manufacturing process.

In addition, the enhancement of personal computer processing speed is generally achieved through the combination of different functions of interface cards. Taking graphics cards as an example, manufacturers have launched products with faster processing speed one after another to meet consumers' requirements so that all the working clocks of the chips on the graphics card are up to hundreds of megahertz, and thus, heat comes with the high frequency working speed.

Therefore, if high heat generated in a graphics card cannot be excluded through effective cooling designs, power consumption is increased in a less serious case, and much worse, electronic components might be damaged to shorten processor life such that the efficiency, reliability and stability of processor will be affected seriously.

So, some manufacturers have designed a side opening at one side of the graphics card, allowing the heat generated from the graphics card to be dissipated by the wind flowing in the side opening to achieve the purpose of cooling. But, such kind of cooling technology only has a limited cooling effect, and bad cooling still happens often to lead to some problems such as temperature being too high in the graphics card.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a multi-directional cooling structure for an interface card, allowing the heat collected by first and second cooling plates to be dissipated quickly through a heat conduction element and cooling fin sets through the particular designs of the heat conduction element and cooling fin sets, advantageously achieving multi-directional heat dissipation.

To achieve the object mentioned above, the present invention proposes a multi-directional cooling structure for an interface card, including: a first cooling plate, configured on the interface card; a second cooling plate, configured at one side of the first cooling plate; at least one heat conduction element, configured on the first cooling plate and second cooling plate, and including a first heat conduction portion positioned on the first cooling plate and a second heat conduction portion in connection with the first heat conduction portion and positioned on the second cooling plate; and at least one cooling fin set, configured on one side of the heat conduction element away from the first and second cooling plates, and in direct contact with the heat conduction element. Whereby, the heat generated from the interface card is collected by the first cooling plate and then transferred to the second heat conduction portion through the first heat conduction portion of the heat conduction element, the second cooling plate sharing responsibility for the absorption of the heat. At the same time, the heat is conducted to the cooling fin sets from the surface of the heat conduction element. It can be known from the above description that the heat can be conducted not only to one side through the heat conduction element but to the cooling fin sets above, advantageously achieving multi-directional heat dissipation.

When the first and second cooling plates1,2receive the heat from the interface card4, the heat can be conducted to the second bending portion321and second heat conduction portion32through the first heat conduction portion31and first bending portion311through the heat conduction element3, advantageously forming horizontal heat conduction to the colder zone of second heat conduction plate2. More importantly, the first and second heat conduction portions31,32are respectively in direct contact with the cooling fin set4through the thermally conductive patches33so as to facilitate the heat conduction; it is namely that the heat can be dissipated simultaneously through the thermally conductive patches33and cooling fin set4when it is conducted from the first heat conduction portion31to second heat conduction portion32, advantageously achieving horizontal and vertical heat dissipation. Furthermore, the above heat conduction element3is made of copper or other highly heat-conductive material.

From the description mentioned above, the present invention has the following advantages over the prior arts: the particularly designs of the heat conduction elements3and cooling fin sets4allows the heat collected by the first and second cooling plates1,2to be dissipated quickly through the heat conduction elements3and cooling fin sets4, advantageously achieving multi-directional heat dissipation.
