As shown in Figure 2, separate type radiating subassembly of the present utility model comprises a disassembling part 2 and a fixed part 4.
This disassembling part 2 has one in the present embodiment and is formed and rectangular flat body 21 by aluminum casting, this body 21 has a first side 23, extend by these body 21 first sides 23 again and be provided with one first contact site 25, this first contact site 25 is a flange in the present embodiment, and by these body 21 upper surfaces along the first side 23 toward sunken insides, thereby form a stepped first step 250 with these body 21 lower surfaces, in addition, in the present embodiment, be provided with a heat pipe 27 at body 21 upper surfaces, this heat pipe 27 is in the mode of welding one end 271 and body 21 to be interconnected, the other end 273 then extends near the first side 23 of this body 21, this body 21 is respectively equipped with a pilot hole 28 in corner, a diagonal angle, wherein a pilot hole 28 is located at first contact site, 25 1 sides, this two pilot hole 28 all penetrates this body 21, and its effect please be held the back explanation, and this disassembling part 2 then is attached on the central processing unit (CPU) 6 of a computer inside with the lower surface of body 21.
Said fixing portion 4 has a pedestal 41 that is formed by aluminum casting in the present embodiment, this pedestal 41 has the second side 43 of this first side 23 of connection, be extended with one second contact site 45 along this second side 43 equally, this second contact site 45 is opposite with the design of first contact site 25, second contact site 45 also is a flange, and protrude outward and form a stepped second step 450 with these pedestal 41 upper surfaces from these pedestal 41 lower surfaces, make this second step 450 and this first step 250 form corresponding matching, and pilot hole 28 places on these second contact site, 45 corresponding first contact sites 25 also are provided with a pilot hole 48, adjacent side 44 extensions in these pedestal 4 second sides 43 are provided with a plurality of radiating fins that are parallel to each other 47, these radiating fins 47 are by adjacent side 44 past direction settings away from this pedestal 41, and in the present embodiment, these radiating fins 47 are provided with a groove 471, this groove 471 is to supply the other end 273 of heat pipe 27 to set up usefulness, so the shape of this groove 471 designs with the profile of heat pipe 27 other ends 273, make the other end 273 of this heat pipe 27 successfully be set up in this, also be equipped with on this pedestal 41 one be communicated with between these radiating fins 47 every bridging portion 410, this bridging portion 410 penetrates this pedestal 41 and is provided with three supports 411 with symmetrical manner in this bridging portion 410, these three supports 411 support a fan 49 simultaneously, and this fan 49 is connected with the computer internal electric.
During assembling, cooperate shown in Fig. 3,4, earlier the pedestal 41 of fixed part 4 is located at a side of central processing unit 6, and the second side 43 that makes this fixed part 4 is towards central processing unit 6, the mode of its setting can be with modes such as the fastening or welding of screw, these connected modes are identical with existing general technology, so no longer be described in detail at this.Then, again this disassembling part 2 is attached on the central processing unit 6 with body 21 lower surfaces, and make these first contact site, 25 cross-over connections on second contact site 45, and the pilot hole 48 that allows pilot hole 28 on this first contact site 25 aim on second contact site 45, and the other end 273 that makes heat pipe 27 is set up in the groove 471 on these radiating fins 47, and form preferable thermally conductive pathways for this heat pipe 27 is fully contacted with groove 471, present embodiment also is provided with the fixedly briquetting 7 of a rectangular plate shape on these radiating fins 47, fixedly be provided with pilot hole 71 in 7 four jiaos of places of briquetting at this, and be located on these radiating fins 47 with four screws (figure do not show), this fixedly briquetting 7 other end 273 of heat pipe 27 more closely is pressed in the groove 471.
The heat dissipation path of present embodiment central processing unit 6 be earlier with heat conduction in this disassembling part 2, this disassembling part 2 utilizes contacting of first contact site 25 and second contact site 45 again, and the contacting of heat pipe 27 and these radiating fins 47, heat is passed to fixed part 4 again, and the heat conduction between this disassembling part 2 and the fixed part 4, because contacting of first contact site 25 and second contact site 45 arranged, so, the size of heat pipe 27 can reduce occupied space by less thin caliber, if the mutual heat transfer of this first contact site 25 and second contact site 45 has been enough to assist central processing unit 6 heat radiations, this heat pipe 27 just can not need be set, and conducted behind these radiating fins 47 when hot, utilize fan 49 on this fixed part 4 to blow the air-flow of 47 of these radiating fins again, make heat by air-flow and dissipation.
In sum, the advantage of separate type radiating subassembly of the present utility model and effect are as described later:
1. when desire is installed or is changed this central processing unit 6, only need very thin disassembling part 2 is taken apart, just can do and install or change, make the utility model in the narrow and small computer in an inner space, install or displacement becomes convenient during as members such as central processing units 6, and the utility model integral thickness is thin, can be more flexible for the utilization of computer inner space.
2. on the pedestal 41 of radiating subassembly, directly be concaved with a bridging portion 410, and a fan 49 is set in this bridging portion 410, and the housing of this fan 49 directly replaces with this radiating subassembly, thereby can save space and cost.
