Heat sink memory chip
A heat sink for chips includes two heat dispensing units and each heat dispensing unit includes multiple fins between which passages are defined. Each heat dispensing unit includes a flat surface defined in an inside thereof and a heat conducting member is connected to the flat surface. The chip is in contact between the two heat conducting members so that the heat generated from the chip is contacted to the heat conducting members and the fins and escapes to the air.

(1) Field of the Invention
The present invention relates to a heat sink for providing a larger heat dispensing area to the chips.
(2) Description of the Prior Art
The chips used in electronic devices such as computers generate a significant heat during operation and the heat may damage the chips so that how to remove the heat from the chips becomes a serious problems. A conventional way to remove heat from the chip is to provide two heat dispensing plates between which the chip is clamped, the heat generated from the chip is conducted to the heat dispensing plates and escapes to the air.
However, the latest chips generate much higher heat than those made by old technology so that the conventional heat dispensing plates cannot remove the heat efficiently. This is because the area that heat is transferred from the chip is insufficient and the conventional heat dispensing plates can only remove a certain amount of heat because of limited heat dispensing area.
The present invention intends to provide a heat sink for chips and includes two heat dispensing units between which the chip is clamped. Each heat dispensing unit includes multiple fins between which passages are defined, so that heat can be efficiently removed from the chip by the heat dispensing units.
SUMMARY OF THE INVENTIONThe present invention relates to a heat sink for chips and the heat sink comprises two heat dispensing units and each heat dispensing unit includes multiple fins between which passages are defined. A flat surface is defined in an inside of each heat dispensing unit and a heat conducting member is connected to the flat surface of each heat dispensing unit. The chip is in contact between the two heat conducting members.
The primary object of the present invention is to provide a heat sink which has a heat conducting member connected between the chip and multiple fins so as to efficiently remove heat from the chip.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The chip 3 generates heat which is conducted to the heat conducting members 2 which are directly connected with the fins 11 so that heat is then conducted to the fins 11 which provides sufficient area to allow the heat to escape to the air. When cooperated with a fan unit (not shown), the fan unit generates air flows flowing through the passages 13 to quickly bring heat out from the fins 11.
The present invention is simple and easily to use, the chip 3 is simply attached to the heat conducting members 2. Not like the conventional heat sink, the chip and the heat sink has to be connected to each other by clips.
Because each heat dispensing unit 1 has the flat surface 12 which is connected to the heat conducting member 2 so that the contact area between the conducting members 2 and the chip 3 is large enough to bring out heat efficiently.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
