Radiator Fixture

technical field

The utility model relates to a radiator fixing device, in particular to a fixing device which utilizes the elastic force of the elastic fixing part itself to fix the radiator.

Background technique

With the improvement of computer computing functions, the internal electronic components, such as central processing unit (Central Processing Unit, CPU), hard disk drive (Hard Disk Drive, HDD), etc., process data faster and higher, and the size of internal electronic components tends to be Miniaturization leads to a higher density per unit area, and an increase in the heat generation density of related electronic components. If the heat is not discharged in time, the high temperature will seriously affect the stability and efficiency of computer operation. It will shorten the life of electronic components.

In order to quickly dissipate the high heat energy emitted by the electronic components, heat sinks such as cooling fins and cooling fans are added to the electronic components to ensure the stable operation of the computer system. In order to make the heat sink and the electronic components in stable and close contact, the known method of fixing the heat sink uses screws to pass through the corresponding screw holes on the heat sink and the circuit board, so that the heat sink and the electronic components are in close contact. Since a radiator must be equipped with multiple screws, for the user, the steps of locking and dismounting the screws are too complicated and time-consuming during the process of installing and dismounting the radiator, which is quite inconvenient, and it is easy to be damaged due to excessive locking force. Cause deformation of the circuit board or heat sink, resulting in shortened service life of the parts.

Another known way of fixing the heat sink is to use a fastener to firmly combine the heat sink with the electronic components. However, the user also needs to apply Only a certain amount of force can be used to open the fastener and install the radiator in the radiator fastener. If the force is not applied properly, it is very likely to cause damage to the radiator fastener or the radiator and electronic components. In addition, since the known radiator fasteners use two opposite fasteners to fix the radiator, it is very easy to cause uneven force on both sides of the radiator, so that the radiator cannot be in close contact with the electronic components, thereby affecting the heat dissipation effect. Moreover, the working space required by the known fasteners is too large, resulting in a relative increase in the volume of the electronic device, which does not meet today's requirements for light, thin and small electronic devices.

The sliding part is connected to the side of the fixing part away from the circuit board, wherein the edge of the other side of the heat sink slides on the sliding part and fits into the second notch, so that the heat sink contacts the heating component.
