When the CNC instrument is running, external air can enter the installation slot 2 through the heat dissipation holes 6, and circulate between the heat sink fins 5 through the ventilation holes 7, and then carry the heat dissipated by the heat sink fins 5, and finally be discharged through the heat dissipation holes 6. Due to the presence of the heat dissipation holes 6 and the ventilation holes 7, the heat dissipation can be accelerated, thereby improving the heat dissipation effect of the heat sink fins 5.

[0023] See also Figure 1-3As shown, locking components are provided on the four corners of the heat conducting plate 4, and the locking components include a retractable latch 8, and a plurality of latch grooves 9 for the latch 8 to be inserted are provided on the inner side wall of the mounting groove 2. When the heat dissipation component needs to be installed, the heat dissipation component can be first embedded in the mounting groove 2 so that the latch 8 is aligned with the latch groove 9, and then the latch 8 is pushed out and inserted into the latch groove 9. By limiting the latch 8 by the latch groove 9, the heat dissipation component can be locked in the mounting groove 2, so that the heat dissipation component can be firmly installed. When the heat dissipation component needs to be removed, the latch 8 only needs to be retracted and withdrawn from the latch groove 9 to release the lock of the heat dissipation component, so that the heat dissipation component can be removed from the mounting groove 2 conveniently. The operation is relatively convenient and simple. The locking component includes a connecting seat 10, and the latch 8 is slidably connected to the inside of the connecting seat 10. A slide groove 11 is provided, and a push piece 12 that passes through the slide groove 11 is provided on the tongue 8. The tongue 8 can be pushed out and retracted into the connecting seat 10 by pushing the push piece 12 to slide along the slide groove 11. The setting of the push piece 12 can provide a force point for the operation of pushing the tongue 8 to extend and retract, thereby making the operation easier and more labor-saving. A support spring 13 is provided inside the connecting seat 10, and one end of the support spring 13 is fixed to the inner wall of the connecting seat 10, and the other end is connected to the tongue 8. The support spring 13 is used to make the tongue 8 extend out of the connecting seat 10 in a natural state.

Among them, the push-up assembly includes a push-up spring 14 fixedly connected to the inner bottom wall of the mounting groove 2, a push plate 15 is connected to the push-up spring 14, and an embedding groove 16 for embedding the push plate 15 is provided on the heat conductive plate 4. After the heat sink assembly is installed inside the mounting groove 2, the heat conductive plate 4 will resist the push plate 15, so that the push-up spring 14 is compressed and deformed. After the locking of the heat sink assembly by the locking assembly is released, the push-up spring 14 will automatically stretch and restore its original shape, thereby being able to push the push plate 15 to embed into the embedding groove 16, and push the heat sink assembly out of the mounting groove 2, so that the heat sink assembly protrudes from the outside of the mounting groove 2, and the operation is relatively convenient and simple.
