Abstract
Description
The present invention relates to a heat sink fastening device and a heat sink assembly including the same.
BACKGROUND ART [0002] In recent years, an integrated circuit package has been used in electronic devices requiring miniaturization and high reliability. The heat generated from the integrated circuit package deteriorates the performance of electronic devices, so heat sinks are combined to dissipate heat.
On the other hand, the heat sink is generally combined with the integrated circuit in contact with the electronic device provided in the integrated circuit package for improving the heat radiation efficiency.
However, when an external force is applied to the heat sink or the electronic device and the heat sink is tilted to one side, there is a problem that the electronic device provided at the bottom of the heat sink or in contact with the heat sink is damaged.
Therefore, there is an urgent need for research to solve this problem.
It is an object of the present invention to provide a heat sink fastening device capable of protecting an electronic device even when an external force is applied to the heat sink, and a heat sink assembly including the heat sink fastening device.
According to an aspect of the present invention, there is provided a heat sink fastening apparatus comprising: a body portion having a split slit on one side; A heat sink support portion extending from the other side of the body portion to a radially outer side of the body portion; A head portion extending from an upper side of the heat sink support portion to a radially outer side of the heat sink support portion; And an elastic member provided on the outer side of the heat sink support portion.
Therefore, even when an external force is applied to the heat sink, the angle at which the heat sink is tilted by the heat sink supporter is minimized, so that breakage of the electronic element provided in the heating element can be prevented.
In addition, in the heat sink fastening apparatus according to an embodiment of the present invention, the heat sink support portion has a rounded shape or an inclined portion that is embedded in the axial direction, thereby reducing the material.
Further, in the heat sink fastening apparatus according to an embodiment of the present invention, the elastic member is provided as a coil spring, and can act as an elastic supporting force.
The heat sink fastening device and the heat sink assembly including the heat sink fastener according to the embodiment of the present invention minimize the angle at which the heat sink is tilted by the heat sink support portion so that even when an external force is applied to the heat sink, Can be prevented.
