For first (two) joint portion 24 (34) is fixed in first (two) conjunction 72 (82), in first (two) conjunction 72 (82) or first (two) joint portion 24 (34) is gone up concavo-convex embedded structure or elastic component (scheming all not show) can further be set.
In addition, in above-mentioned two examples, first (two) cylinder is not an imperative, as long as first, second heat-sink unit has the structure of other correspondence in conjunction with heat conductive rod.
Please refer to " Fig. 4 " the 3rd embodiment exploded view of the shared radiating module of variable bearing pressure is provided for the utility model, the main difference of itself and a last embodiment is that this example is not included in to adjust element and flexible member.Heat conductive rod 40 stage casings are that hexagonal cylinder, two ends have screw thread 41, and first cylinder 22 in first heat-sink unit 20 and second cylinder 32 in second heat-sink unit 30 also have screw thread access slot (324, another does not indicate) and heat conductive rod 40 cooperatively interacts; An amount of heat-conducting cream can be coated aforementioned each screw thread position to promote heat-conducting effect.Above-mentioned member have a specific hand of spiral, when heat conductive rod 40 to direction rotation, its two ends will screw in first cylinder 22 and second cylinder 32 simultaneously, when heat conductive rod 40 rotates to other direction, its two ends will screw out first cylinder 22 and second cylinder 32 simultaneously.So, by the relative rotation of heat conductive rod 40 with first (two) heat-sink unit 20 (30), the spacing of first and second heat- sink unit 20,30 can be adjusted, that is the integral width of shared radiating module can be changed a little.Be the rotary manipulation of convenient heat conductive rod, its stage casing also can be the polygonal cylinder beyond the hexagonal cylinder.
In this example, first (two) cylinder is not an imperative, as long as first, second heat-sink unit has the structure of other corresponding heat conductive rod screw thread, for example screw etc. can reach same effect.Secondly, heat conductive rod is to be connected between first, second heat-sink unit in the mode of being coupling basically, only needs an end to connect in the mode of being spirally connected, and can change the spacing of first, second heat-sink unit a little when heat conductive rod rotates.
On the other hand; among aforementioned all embodiment; the concavo-convex embedded structure of various member correspondences can be opposite convex-concave structure replace, size and the position of flexible member can change accordingly simultaneously, this class formation is alternative also should to be covered by in technological thought of the present utility model and the protection range.
For example, first cylinder 22 and second cylinder 32 also can be solid cylinder, heat conductive rod 40 two ends have the groove that cooperates first cylinder 22 and second cylinder 32 under this situation, and coupling has other existing binding mechanism to make heat conductive rod 40 two ends can distinguish fluid-tight engagement first cylinder 22 and second cylinder 32, and is unlikely to come off.
The first above-mentioned joint portion 24, second joint portion 34 can be exchanged mutually with first conjunction 72, second conjunction 82 and form opposite chimeric slide mechanism, first (two) binding site that is the evagination long plate shape is on first (two) radiating bottom plate, and first (two) conjunction of U-shaped frame shaped then is positioned at first (two) the heat-sink unit body dorsal part.So with first heat-sink unit 20, when second heat-sink unit 30 is assembled in first radiating bottom plate 70, second radiating bottom plate 80, can cooperate, adopt the convenience of the mode of slip, and then significantly reduce the required time of assembling with the lifting assembling by it.
At last, though previous embodiment is an example with two flexible members all, in practical application, the unitary elasticity element enough reaches and changes the effect of sharing the radiating module width; And being connected of heat conductive rod and the first/the second cylinder, the effect that make at least, second heat-sink unit has relative displacement gets final product, and another can be fixed connection.Certainly, many groups is adjusted element and flexible member should belong to simple variation of the present utility model.
