Fastening structure of radiator and fan

【Technical field】

The utility model relates to a fastening structure of a radiator and a fan, in particular to a fastening structure which uses a detachable and easy-to-assemble fastening piece to combine and fix the radiator and the cooling fan.

【Background technique】

The computer has become one of the irreplaceable important tools in the life of modern people. It provides people with better work performance. With the advancement of technology, the processing speed of the computer has been continuously improved. The computer achieves good performance, and the radiator installed on the central processing unit (CPU) has also become one of the important components. The heat dissipation structure of the radiator can be divided into two separable parts, one of which is attached to the central processing unit (CPU). The radiator body on the radiator, and the other part is the cooling fan attached to the end of the radiator;

In the way of fixing the cooling fan on the radiator, the most widely used existing technology is that several long screw holes are formed inwardly around the tail end of the radiator body, and the corresponding heat dissipation of the radiator There are several perforations formed around the fan that correspond to the screw holes, so that several long screws can pass through the holes of the cooling fan and be connected to the long screw holes of the radiator body by corresponding screws. It takes a lot of time to connect and disassemble the heat dissipation fan by screwing one pair of holes one by one. Therefore, the connection between the heat sink and the heat dissipation fan in the prior art is convenient in practice. The disadvantage is that most of the long screws used for locking in the prior art are made of hard materials without shock absorption effect, so when the fan is running at high speed, it is easy to vibrate and cause unnecessary noise.

【Content of invention】

In view of the above-mentioned shortcomings of the prior art, the utility model designs a fastening structure that uses a detachable and easy-to-assemble fastening piece to combine and fix the radiator and the cooling fan.

In order to achieve the above purpose, the technical solution adopted by the utility model is to design a fastening structure of a radiator and a fan, which includes:

A cooling fan, a plurality of perforations formed at intervals on the outer frame;

A heat sink, which is adjacent to the heat dissipation fan and has a gap formed at the place where the heat dissipation fin is provided and corresponds to the through hole;

A plurality of fastening parts, which include a detachable fastening sleeve and a fastening block; the fastening sleeve is a long kit, one end of the fastening sleeve is raised to form a head end, and the outer diameter of the bottom of the head end is It is larger than the hole diameter of the hole on the cooling fan, and the other end protrudes to form a card end. The outer diameter of the card end is larger than the hole diameter of the hole on the cooling fan, and a concave hole is formed on the end surface of the card end; one end of the fastening block is extended There is a buckle bar, which can be correspondingly threaded and fixed in the recess of the fastening sleeve. The other end of the fastening block is longitudinally spaced and formed with a plurality of plugs corresponding to the gaps between the cooling fins, and each plug Extending forward from the bottom end, a positioning block is laterally connected to each other, and the positioning block is correspondingly matched with the gap on the heat dissipation fin at the perforation.

When the utility model is in use, on the one hand, firstly set the buckle-fitting and slip-on at the perforation of the cooling fan, and then use the positioning block of the buckle-fitting block to correspond to the notch position of the heat-dissipating fin at the perforation and at the same time use the plug After corresponding to the gap between the heat dissipation fins, push the fastening block into the heat dissipation fins to fix it at the corresponding perforation position, and then through the fastening and fastening between the corresponding fastening parts The heat dissipation fan and the heat sink are snapped together; and the utility model has the advantage that after the user fixes the detachable fastening parts on the heat dissipation fan and the heat sink respectively, the heat dissipation fan can be fixed by simple alignment and pushing actions and heat sink, which can save operating time compared with the fixing method of an externally extended screw; moreover, if the fastening part is made of elastic material, it can be used to fasten the clip end of the sleeve and the fastening block The contact between the support arm and the buckle provides a shock absorption and buffering effect between the cooling fan and the radiator, thereby reducing unnecessary noise.

Please refer further to FIG. 2 , the aforesaid cooling fan 10 is a conventional heat dissipation device used for heat dissipation of the central processing unit, and it is spaced and formed with a plurality of axial perforations 11 at intervals on the peripheral frame of the air inlet end.

Aforesaid heat sink 20 is a heat dissipation device that is applied to the heat dissipation of central processing unit. On its tail end, there are a plurality of heat dissipation fins 21 arranged in an axial direction and arranged adjacent to each other in sequence. The air inlet end of the fan 10 is adjacent to each other. In addition, a notch 22 is formed on a part of the cooling fin 21 corresponding to the hole 11 . The notch 22 is concavely formed on the side edge of the cooling fin 21 near the tail end.

The above-mentioned fastening member 30 can be further divided into a fastening sleeve 31 and a fastening block 32;

Please refer to Figure 3 for further cooperation. The fastening sleeve 31 is made of compressible elastic material. A slightly arrow-shaped head end 311 is formed. The outer diameter of the bottom of the head end 311 is larger than the aperture of the perforation 11. On the side edge of the other end of the fastening sleeve 31, a card end 312 protrudes toward the section surface. The card end 312 The outer diameter of the hole 11 is also greater than the diameter of the perforation 11, and a recess 313 is concavely formed on the end surface of the card end 312. The recess 313 is elongated and presents a tapered inner diameter near the chamber 314. A chamber 314 with a larger inner diameter is formed at the center, and a joint is formed at the junction of the bottom end of the chamber 314 and the recess 313 due to the difference in relative aperture;

Please refer to Figures 4 and 5 for further cooperation. The buckle block 32 can be made of a slightly elastic shock-absorbing material, and one end of it is extended to form a buckle rod 321. The outer diameter of the shaft section of the buckle rod 321 is matched with the buckle The concave cavity 313 of the sleeve 31 can be correspondingly penetrated therein, and the head end of the buckle rod 321 is protruded to form a buckle portion 322 corresponding to the chamber 314, and the outer diameter of its cross section is larger than the aperture of the concave cavity 313, so it can When the buckle rod 321 is installed inside the cavity 313, the bottom of the buckle portion 322 is engaged and fastened on the joint surface of the bottom end of the chamber 314, so that the buckle block 32 and the buckle sleeve 31 are connected to each other.
