Abstract

The invention provides a heat dissipation device assembly comprising a heat sink and a fastening tool, and a through hole is arranged on the heat sink. The fastening tool comprises a fastening assembly, an elastic element and a columnar hollow fastener mating with the fastening assembly, wherein the fastening assembly comprises a pressing portion, a body extending form the pressing portion and a combination portion extending form the body, a flange is arranged at the joint position of the body and the combination portion, a slot and a stop block extending inwardly along the radial direction of the fastener are arranged on one end of the fastener which is closer to the pressing portion of the fastening assembly, the elastic element is sleeved on the body of the fastening assembly, two ends of the elastic element abut against the pressing portion of the fastening assembly and the heat sink respectively, and the combination portion of the fastening assembly extends into the hollow fastener and the flange of the body abuts against the bottom of the stop block of the fastener to make the fastener to abut against the heat sink under the elastic force of the elastic element. The invention also discloses an electronic device using the heat dissipation device assembly.

Description

technical field [0001] The invention relates to an electronic device, in particular to a heat dissipation device combination of the electronic device and a buckle of the heat dissipation device combination. Background technique [0002] With the rapid development of the computer industry, more and more heat is generated by electronic components such as the central processing unit. components to dissipate heat. This kind of heat sink is fixed on the circuit board by means of a fixing fastener such as a spring screw with a threaded end provided with the circuit board and threadedly engaged with the circuit board. In this way, during the use of the heat sink, when the spring exerts a large preload, the circuit board may be severely deformed and the internal structure of the heat-generating electronic component may be damaged, thereby affecting the working performance of the heat-generating electronic component. Contents of the invention [0003] In view of this, it is neces...
