Detailed Description
Example one
For convenience of description, a coordinate system is now defined for the heat sink as shown in fig. 2.
As shown in fig. 2 and 4, the heat dissipation device for the pipeline of the steering power-assisted system of the light truck comprises a mounting sheet 1, wherein the mounting sheet 1 comprises a wrapping part 11 with a circular section, and as shown in fig. 1, the wrapping part 11 is wrapped on a steering pipeline 7. The wrapping part 11 is provided with a notch which axially penetrates through the wrapping part 11, and the central angle corresponding to the notch is smaller than 30 degrees. The wrapping portion 11 is provided with a first connecting portion 12 and a second connecting portion 13 which extend outwards and are located on two sides of the notch respectively, the first connecting portion 12 and the second connecting portion 13 are parallel to each other, and the first connecting portion 12 and the second connecting portion 13 are symmetrically arranged on a symmetrical plane of the wrapping portion 11.
The first connecting portion 12 and the second connecting portion 13 are fixedly connected through the screw 3 and the lock nut 4, and the wrapping portion 11 is tightly hooped on the steering pipeline 7 under the locking action of the screw 3 and the lock nut 4. That is, when the first connecting portion 12 and the second connecting portion 13 are brought into contact with each other by the pressing action of the screw 3 and the lock nut 4, the inner diameter of the wrapping portion 11 is smaller than the outer diameter of the steering pipe 7. The first connecting portion 12 and the second connecting portion 13 are respectively provided with a through hole for accommodating the screw 3.
The wrapping part 11 of the mounting piece 1 is provided with a plurality of radiating fins 2 extending along the axial direction, and the plurality of radiating fins 2 are arranged in a radial shape. As a specific embodiment, nine cooling fins 2 are provided on the wrapping portion 11 described in the present embodiment.
Further, in order to increase the surface area of the fins 21 and thus increase the heat dissipation area, as shown in fig. 4, the free end of the heat sink 2 is provided with the fins 21, the cross section of the fins 21 is circular-arc-shaped, and the fins 21 are symmetrically arranged with respect to the heat sink 2. Preferably, the fins 21 have the same diameter and the same arc length.
Further, for convenience of installation, as shown in fig. 5, the heat sink 2 is disposed in the middle of the wrapping portion 11 in the left-right direction, and the length of the heat sink 2 is smaller than that of the wrapping portion 11. Two screws 3 are arranged between the first connecting part 12 and the second connecting part 13, and the two screws 3 are respectively positioned at the left side and the right side of the radiating fin 2.
Further, as shown in fig. 3 and 6, the first clamping plate 5 and the second clamping plate 6 are respectively arranged on the outer sides of the first connecting portion 12 and the second connecting portion 13 (the side opposite to the first connecting portion 12 and the second connecting portion 13 is taken as the inner side), and the through holes for accommodating the screws 3 are respectively arranged on the first clamping plate 5 and the second clamping plate 6.
The reason for this is that to ensure good heat dissipation, good contact between the wrapping portion 11 and the steering pipe 7 is ensured, and due to machining errors, there is necessarily a certain error between the actual outer diameter and the design size of the steering pipe 7. In this case, if the wrapping portion 11 of the attachment piece 1 is of a rigid structure, it is difficult to ensure close contact between the wrapping portion 11 and the steering pipe 7. This scheme, fin 2 arranges along the axial on the one hand, can guarantee that parcel portion 11 has certain elasticity. On the other hand, by arranging the first clamping plate 5 and the second clamping plate 6 and enabling the inner ends of the first clamping plate 5 and the second clamping plate 6 to abut against the outer side surface of the wrapping part 11, when the first clamping plate 5 and the second clamping plate 6 approach each other under the locking action of the screw 3 and the locking nut 4, the diameter of the wrapping part 11 can be reduced along with the inner ends until the wrapping part 11 is tightly attached to the outer diameter of the steering pipeline 7. This design not only ensures close contact between the wrapping portion 11 and the steering pipe 7, but also ensures uniformity of contact between the wrapping portion 11 and the steering pipe 7 in the longitudinal direction by the design of the first clamp 5 and the second clamp 6.
Further, as shown in fig. 3 and 6, inner end surfaces (an end close to the wrapping portion 11 is an inner end) of the first splint 5 and the second splint 6 are arc surfaces having a semicircular cross section. The diameter of the arc surface is equal to the diameter of a transition fillet at the joint of the wrapping part and the first connecting part and the second connecting part.
Further, a layer of heat-conducting silica gel (not shown in the figure) is fixedly disposed on the inner side surface of the wrapping portion 11, and as a specific implementation manner, the heat-conducting silica gel in this embodiment is fixedly connected with the wrapping portion 11 in a sticking manner.
Example two
The fin 21 is arranged at the suspended end of the radiating fin 2, the fin 21 is a flat plate, the radiating fin 2 and the fin 21 form a T-shaped structure together, and the rest of the structure is the same as that of the first embodiment.
