Abstract

The utility model relates to a radiator assembly comprising a radiator and four sets of buckling devices fastened on the radiator. The radiator comprises a base and a plurality of radiation fins upward extending from the base, wherein, in the position of the base, four holes are arranged. Each set of buckling devices comprises tape head bolt, a spring sheathed on the bolt and a fixed sheet arranged on the bolt. The end of the bolt is provided with a fork-shaped fastening part passing through the holes of the radiator to be buckled on the top surface of the base. The fixed sheet is provided with a notch which approximately presents a C shape, and the inner diameter of the notch approximately equals to the diameter of the bolt. After the fixed sheet is arranged on the bolt, the spring can be prevented from falling off the bolt.

Description

The radiator combination

The utility model makes up about a kind of radiator, especially refers to the radiator combination that a kind of simple installation and packaging efficiency are high.

Along with developing rapidly of information industry, the arithmetic speed of the inner set wafer of electronic installation (quickening wafer as central processing unit and figure) is more and more faster, and the ability of its deal with data is also more and more stronger.Yet, follow speeding of wafer arithmetic speed, the heat that it produced also increases considerably.For these heats can promptly be discharged, wafer can be moved under normal working temperature, to guarantee the quality of data processing, storage and transmission, install radiator combination usually at the wafer place.Please refer to No. 016, Taiwan patent application the eight or six 211, it discloses a kind of existing radiator combination, comprises a radiator, two clamping parts and two-screw.The installation process of this radiator combination is: clamping part is crossed on the no fin district of radiator, and the clasp of clamping part is fastened on the central processing unit card casket in the default button hole; Again with the screw screw lock in the set nut of clamping part, and the end of screw is held in no fin district; At last, rotary screw by the action pull-up clamping part of screw, makes the clasp of the clamping part inner surface of central processing unit card casket that links closely, and under the acting in conjunction of clamping part clasp and screw end, radiator and central processing unit card casket is fitted tightly.But, because the fin height of radiator is very high and arrange tight, thereby this class radiator is combined in the installation process, can be subjected to the influence of fin and need the auxiliary fitting operation that just can finish clamping part and screw of suitable instrument in addition, therefore installation process is easy inadequately, and packaging efficiency is not high.

The purpose of this utility model is to provide a kind of simple installation and the high radiator combination of packaging efficiency.

The utility model is reached above-mentioned purpose by following means, and this radiator combination comprises a radiator, and four groups of buckling devices that are buckled on the radiator.This radiator comprises a pedestal and some from the upwardly extending radiating fin of pedestal, and this pedestal in position locates to offer four holes.Every group of buckling device comprises that taking the lead roofbolt, is set in a spring on the roofbolt and a stator that is installed on the roofbolt.The end of this roofbolt is provided with a forked clamping part, is used for passing the hole of radiator and is fastened on base top surface.Stator is provided with a kerf and roughly is the C font, and its internal diameter approximates the diameter of roofbolt, after this stator is installed on the roofbolt, can prevent that spring from coming off from roofbolt.

Compare prior art, the combination of the utility model radiator has simple installation, combined efficiency advantages of higher.

The accompanying drawing simple declaration:

Fig. 1 is the isometric exploded view of combination of the utility model radiator and central processing unit card casket.

Fig. 2 is the three-dimensional assembled view of the part of Fig. 1.

Fig. 3 is the three-dimensional assembled view of Fig. 1.

Below in conjunction with embodiment and with reference to accompanying drawing, the utility model will be further described:

Please together with reference to figure 1,2 and 3, decompose and assembled view for the solid of combination of the utility model radiator and central processing unit card casket, wherein this central processing unit card casket 10 comprises that a housing 30 and is installed in the printed circuit board (PCB) 50 on the housing 30.The middle part weldering of these printed circuit board (PCB) 50 end faces is provided with central processing unit 52, and offers a hole 54 near the quadripolar corners of central processing unit 52 respectively.This housing 30 has the structure that matches with printed circuit board (PCB) 50, and offers hole 32 in the position of corresponding printed circuit board (PCB) 50 holes 54.

The combination of the utility model radiator comprises a radiator 70, and four groups of buckling devices 90 that are buckled on the radiator 70.This radiator 70 comprises a pedestal 72 and some from pedestal 72 upwardly extending radiating fins 74, and this pedestal 72 offers hole 76 in the position of corresponding printed circuit board (PCB) 50 holes 54.

Every group of buckling device 90 comprises that taking the lead roofbolt 92, is set in a spring 94 on the roofbolt 92 and a stator 96 that is installed on the roofbolt 92.The end of this roofbolt 92 is provided with a forked clamping part 97, is used for passing the hole 76 of radiator 70 and is fastened on pedestal 72 end faces.Stator 96 is provided with a kerf 98 and roughly is the C font, and its internal diameter approximates the diameter of roofbolt 92, after this stator 96 is installed on the roofbolt 92, can prevent that spring 94 from coming off from roofbolt 92.

During assembling, at first four groups of buckling devices 90 are pre-installed on the central processing unit card casket 10, wherein the roofbolt 92 of this buckling device 90 passes the hole 32 of housing 30 and the hole 54 of printed circuit board (PCB) 50 in order, and the clamping part 97 of roofbolt 92 ends exposes (with reference to figure 2) from the end face of printed circuit board (PCB) 50.Afterwards, radiator 70 is placed on printed circuit board (PCB) 50 end faces, and the hole 76 that makes radiator 70 is aimed at the clamping part 97 of roofbolt 92, by pushing the head of buckling device 90 roofbolts 92, make the forked clamping part 97 of roofbolt 92 ends pass hole 76 on radiator 70 pedestals 72, after decontroling hand, the clamping part 97 of these roofbolt 92 ends will be buckled in pedestal 72 end faces of radiator 70 because of the elastic force of spring 94, and radiator 70 and central processing unit 52 are fitted tightly.

Because buckling device 90 of the present utility model and radiator 70 lay respectively at the both sides of central processing unit card casket 10, therefore this buckling device 90 set in advance and pressing operation all need be highly very not high and arrange closely and finish in the radiating fin 74, therefore do not need other instrument auxiliary and can directly use manual manipulation, the integral installation process is easy and packaging efficiency is high.In addition, because this spring 94 is to be directly installed on the roofbolt 92 with fixing mode, therefore its internal diameter might come off from roofbolt 92 greater than the diameter of roofbolt 92 and clamping part 97, and the utility model is installed the mode of a stator 96 on roofbolt 92, can prevent that spring 94 from coming off from roofbolt 92.
