Specific embodiment

It should be noted that in the case of not conflicting, following technical proposals, can be mutually combined between technical characteristic.

Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further described:

Present embodiments provide a kind of heat abstractor, as shown in figure 1, the heat abstractor of the present embodiment includes the first fin 1 and l type fin 2, wherein, l type fin and the dismountable connection of electrical equipment being connected on a circuit board, in the present embodiment Electrical equipment be illustrated with mos pipe 3.

As shown in figure 1, offering multiple first through holes 11 on the first fin 1, countersunk head screw 12 passes through first through hole 11 With the through hole on mos pipe 3 so that the first fin 1 can be fixing with mos pipe 3, the quantity of the first through hole 11 in the present embodiment Corresponding with when position and the quantity of mos pipe 3, such as in Fig. 1, the number of mos pipe 3 is 6, and the number of first through hole 11 is also 6 Individual.

First groove 13 is offered on the first fin 1, as shown in Figure 2 and Figure 3, l type fin includes horizontal fin 21 And the vertical fins 22 being connected with horizontal fin 21, the angle between horizontal fin 21 and vertical fins 22 is 90 Degree, wherein, vertical fins 22 offer multiple second through holes 221, and offer on the first fin 1 multiple numbers with The third through-hole 14 that position is all adapted to the second through hole 221, screw 15 passes through the second through hole 221, third through-hole 14 so that l type Fin 2 is detachably secured on the first fin 1, and the second through hole 221 in the present embodiment can be divided into multiple rows of setting.

In the present embodiment, when l type fin 2 is fixed on the first fin 1, horizontal fin 21 and vertically dissipating Connecting line 23 between backing 22 is placed in 13 in the first groove, and the first groove is convenient to place l type fin 2, and l type fin The 2 and first installation positioning between fin 1, save cost of labor.

When the other parts on mos pipe 3 or circuit board are damaged, user can disassemble l type fin 2 With the first fin 1, become extremely convenient to change to the device damaging so that keeping in repair.

In the present embodiment, fixing mos pipe 3 uses countersunk head screw 12, when countersunk head screw 12 sinks to low, permissible L type fin 2 is sufficiently released with the first fin 1, reduces thermal contact resistance, increase the heat conduction seriality of hot-fluid transmission, Heat that mos pipe 3 produces is more enough to be preferably delivered to l type fin by the first fin 1 it is ensured that the usability of mos pipe 3 Energy.

Further, as shown in Figure 2 and Figure 3, the horizontal fin 21 in the present embodiment is further opened with multiple strip through-holes 211, strip through-hole 211 can divide multiple rows of setting, this strip through-hole 211 can for encapsulating when, colloid can sufficiently be filled Inner space and design.

Further, as shown in Figure 2 and Figure 3, the horizontal fin in the present embodiment is further opened with multiple third through-holes 212, the heat abstractor of the present embodiment also includes the second fin (not shown), and the second fin can be fixed or removable The connection unloaded on circuit boards, or connects on device on circuit boards, and screw can pass through third through-hole 212 and second to dissipate Through hole on backing, l type fin 2 and the dismountable fixation of the 3rd fin can be increased using such technical scheme The fixed effect of strong l type fin 2, prevents l type fin 2 mobile.

Further, the first fin 1 in the present embodiment, l type fin 2 and the second fin can be all aluminium flake, Because aluminum has preferable heat-conducting effect, so the material of fin adopts the aluminium material can be with electrical equipment on intensifier circuit plate Radiating effect.

To sum up, in technique scheme, the first fin and l type fin use split type with respect to circuit board Design, when electrical equipment or other parts damage, fin easy to disassemble is keeped in repair, and it is more convenient to use.

By explanation and accompanying drawing, give the exemplary embodiments of the ad hoc structure of specific embodiment, based on present invention essence God, also can make other conversions.Although foregoing invention proposes existing preferred embodiment, however, these contents are not intended as Limitation.
