Description

technical area

The The invention relates to the attachment of a heat sink, through which the heat sink easily and can be fixed quickly.

State of technology

Of the Heat sink is with the object to be cooled, like central unit, in contact to absorb the waste heat of the central unit.

• 1. den Kühler mit dem zu kühlenden Gegenstand löten, kleben oder verschrauben, und
• 2. den Kühler auf dem zu kühlenden Gegenstand festklemmen.

In order to ensure contact between the heat sink and the object to be cooled, the following compounds are usually used:

• 1. Solder, glue or screw the cooler to the object to be cooled, and
• 2. Clamp the cooler on the object to be cooled.

The first connection is difficult to carry out and can the construction of the cooler or the one to be cooled Damage the object. The second connection can not guarantee a uniform clamping force. In addition, you can the clamping parts break.

Out Taiwanese Patent M243906 discloses the attachment of a heat sink, which uses the above-mentioned second compound. This attachment however, is difficult and expensive.

Out For this reason, in view of the disadvantages of the present inventor solutions After a long study, numerous experiments and constant improvements the present invention is developed.

Task of invention

Of the Invention is the object of the attachment of a heat sink create through which the heat sink easily and can be fixed quickly.

Of the Invention is a further object of the attachment of a Heat sink too through which the con tact of the heat sink with the cooled Subject assured can be.

Of the Invention is a still further object, the attachment to a heat sink create, through which the seat is evenly loaded, so that a break of the seat can be avoided.

Of the Invention is a still further object, the attachment to a heat sink create, the low production costs and easy installation having.

Of the Invention is a still further object, the attachment to a heat sink create, which allows adaptation to the object to be cooled.

These Tasks are solved by the inventive attachment of a heat sink, the from a seat, a first positioning unit and a second Positioning unit consists, wherein the first and second positioning unit each contain more than one clamp, each one terminal end and having a mounting end.

Ways to execute the invention

1 shows the first preferred embodiment of the invention, which consists of a seat 11 , a first positioning unit 12 and a second positioning unit 13 consists. The first positioning unit 12 contains more than a clamp 121 a pinch end 121 and an attachment end 121b having. The second positioning unit 13 contains more than a clamp 131 a pinch end 131 and an attachment end 131b having.

Like from the 1 and 2 can be seen, the seat points 11 at the appropriate locations on the outside of a first receiving recess 111 and a second receiving recess 112 for the first and second positioning unit 12 . 13 , In the present embodiment, the first and second receiving recess 111 . 112 each by a first and second groove 111 . 112a and a first and second aperture 111b . 112b educated. Through the first opening 111b becomes the attachment end 121b the clamp 121 the first positioning unit 12 led, after which a bolt 111c through a through hole 121c the clamp 121 is guided, causing the clamp 121 hinged to one side of the seat 11 is attached. Through the second opening 112b becomes the attachment end 131b clamp 131 the second positioning unit 13 led, after which a bolt 112c through a through hole 131c the clamp 131 is guided, causing the clamp 131 hinged to one side of the seat 11 is attached.

Like from the 1 . 2 . 3 . 4 . 5 and 6 it can be seen, during assembly, first, the heat sink 14 in the seat 11 brought ( 3 ), the bottom of the heat sink 14 the attachment end 121b the clamp 121 the first positioning unit 12 and the attachment end 131b the clamp 131 the second positioning unit 13 push down ( 4 ), causing the clamp 121 the first positioning unit 12 and the second clamp 131 the second positioning unit 13 be turned inwards, so that the clamping end 121 the clamp 121 the first positioning unit 12 and the terminal end 131 the clamp 131 the second positioning unit 13 the upper edges 141 . 142 of the heat sink 14 hold down ( 5 and 6 ). Therefore, the heat sink 14 with the central unit 16 on the carrier 15 kept in contact.

7 shows the second preferred embodiment of the invention, in which between the terminals 121 the first positioning unit 12 a footbridge 121d is provided and the second positioning unit 13 only a clamp 131 contains.

8th shows the third preferred embodiment of the invention, in which between the terminals 131 the first positioning unit 13 a footbridge 131d is provided.

9 . 10 . 11 and 12 show the fourth preferred embodiment of the invention, in which the clamp 221 the first positioning unit 22 firmly on one side of the seat 21 and the clamp 131 the second positioning unit 13 hinged on the other side of the seat 21 is attached.

During assembly, one side of the heat sink is initially 14 in the seat 21 brought ( 10 ) and its upper edge 141 from the terminal end 221a clamp 21 the first positioning unit 22 held down ( 11 ). Subsequently, the other side of the heat sink 14 in the seat 21 brought the bottom of the heat sink 14 the attachment end 131b the clamp 131 the second positioning unit 13 push down ( 11 ), making the second clamp 131 the second positioning unit 13 is turned inwards, so that the terminal end 131 the clamp 131 the second positioning unit 13 the top edge 142 of the heat sink 14 holds down ( 12 ). Therefore, the heat sink 14 with the central unit 16 on the carrier 15 kept in contact.

The first and second positioning unit 12 . 13 Both can also be firmly attached to the seat and each have an elasticity so that they can be separated by deformation of the heat sink.

• 1. Durch die Hebelwirkung (die gelenkige Verbinung der Klemmen der Positioniereinheiten mit dem Sitz) können die Klemmen der Positioniereinheiten beim Einsetzen des Kühlkörpers in den Sitz gleichzeitig den Kühlkörper niederhalten.
• 2. Bei der Montage ist die Belastung auf den Sitz gleichmäßig, so daß ein Bruch des Sitzes vermieden werden kann.
• 3. Nach der Montage ist die Klemmkraft auf den Kühlkörper gleichmäßig, so daß ein Kontakt des Kühlkörpers mit der Zentralheit gewährleistet werden kann.
• 4. Die Herstellungskosten sind niedriger und die Montage ist einfacher.
• 5. Die Anzahl der Klemme kann je nach dem Kühlkörper, wie rundem Kühlkörper, gewählt werden.
• 6. Die erste und zweite Positioniereinheit können je nach Bedarf fest oder gelenkig an dem Sitz befestigt werden.

The advantages of the invention are summarized below:

• 1. Due to the leverage effect (the articulated connection of the positioning unit clamps with the seat), the terminals of the positioning units can simultaneously hold down the heat sink when inserting the heat sink into the seat.
• 2. When mounting the load on the seat is even, so that a breakage of the seat can be avoided.
• 3. After installation, the clamping force on the heat sink is uniform, so that contact of the heat sink with the centrality can be ensured.
• 4. The manufacturing costs are lower and the assembly is easier.
• 5. The number of clamps can be selected according to the heat sink, such as round heat sink.
• 6. The first and second positioning units can be fixed or hinged to the seat as needed.

by virtue of the above facts, the invention corresponds in its availability, Progressiveness and novelty fully on the requirements for a utility model.

The The above description represents only the preferred embodiments of the invention and should not be used as a definition of boundaries and the scope of the invention, the NEN. All equivalent changes and modifications are included to the scope of this invention.
