[0034] The present application provides three embodiments of heat sinks as examples. Structures equivalent to the embodiments are also within the protection scope of the present application and are not limited here.

[0035] Embodiment 1:

[0036] like Figure 1-2As shown, the second heat dissipation component is a first triangular prism 2, and the second heat dissipation component includes a second triangular prism 11 and a third triangular prism 12. One of the quadrilateral sides of the first triangular prism 2 is the lower end face, and the other two quadrilateral sides are arranged upward, one quadrilateral side of the second triangular prism is in contact with one of the quadrilateral sides of the first triangular prism arranged upward, and one quadrilateral side of the third triangular prism 12 is in contact with one of the quadrilateral sides of the first triangular prism 2 arranged upward. The upper end faces of the second triangular prism and the third triangular prism together form the upper end face of the first heat sink. The width of the quadrilateral side of the first triangular prism as the lower end face = the width of the upper end face of the second triangular prism + the width of the upper end face of the third triangular prism. The side triangle of the first triangular prism is an isosceles triangle, and the corresponding second triangular prism has the same shape and size as the third triangular prism. When the three triangular prisms are placed in the specified positions, a cube is formed.

[0037] The radiator is height-adjusted by the following height-adjusting component. The height-adjusting component includes a fixing portion 21 and a spring 3. The fixing portion is disposed in the middle of the triangular side surface of the first triangular prism, and mounting holes are provided on the triangular side surface of the second triangular prism and the triangular side surface of the third triangular prism on the same side as the triangular side surface of the first triangular prism. The spring includes two mounting branches and a fixing portion in the middle. The mounting branches are disposed in the mounting holes, and the fixing portion is fixed to the fixing portion. The middle portion here refers to the middle portion of the spring, which is not necessarily the exact middle, as long as it is the middle section. There are two height-adjusting components, which are disposed at corresponding positions of the two triangular sides of the first triangular prism.

[0038] As an example of a fixing part, it includes a cylinder extending outward and a protrusion arranged outside the cylinder. There is a gap between the edge of the cylinder and the protrusion, and the gap is used to fix the fixing part of the spring. The fixing part here can be consistent with the shape of the gap surrounded by the edge of the cylinder and the protrusion.

[0039] Embodiment 2:

[0040] like Figure 3-4 As shown, the first heat dissipation component and the second heat dissipation component are two triangular prisms of the same shape and size, and the triangular side of the triangular prism is a right triangle, that is, a right triangular prism 4. The quadrilaterals on one side of the inclined surface of the two triangular prisms are fitted together, and the hypotenuses of the two right triangles after fitting coincide, and the right triangles of the two triangular prisms are spliced ​​into a rectangle after being combined.

[0041] The height adjustment component includes a spring and mounting holes provided on the first heat dissipation component and the second heat dissipation component. There is a mounting hole on the right-angled triangle side of the first heat dissipation component, and there is also a mounting hole on the right-angled triangle side of the second heat dissipation component. The spring 3 includes two mounting branches, the first mounting branch is mounted on the mounting hole of the second heat dissipation component, and the second mounting branch is mounted on the mounting hole of the first heat dissipation component. In order to increase the height of adjustment, it can be achieved by stacking a plurality of right-angled triangular prisms in series in the aforementioned manner.

[0042] Embodiment three:

[0043] like Figure 5-6 As shown, the first heat dissipation component and the second heat dissipation component are both plate-shaped, and meshing serrated structures are provided on two corresponding edges of oppositely arranged surfaces, that is, the plate body 5 has a serrated structure.

[0044] In order to achieve height adjustment, the height adjustment component is an elastic member with an arc-shaped portion. A groove is provided on the inner side of the sawtooth structure of a heat dissipation component, and the elastic member is arranged in the groove, and the arc-shaped portion of the elastic member is arranged toward the direction of the other heat dissipation component. The elastic member can be a spring or an elastic plastic member.

[0045] On the other hand, the embodiment of the present application provides an optical module installation structure, such as Figure 7 As shown, it includes an optical module socket 8, a heat sink 1, a PCB board and a cold plate 6. The optical module socket 8 is arranged on the PCB board and is powered by the PCB board. A row of optical module sockets are respectively arranged on the upper and lower end surfaces of the cold plate, and the optical module sockets 8 are used to insert the optical modules 7. A heat sink whose height changes with the force is arranged between each row of optical module sockets 8 and an end surface of the cold plate 6. Located on one side of the cold plate, a first gap is provided between the upper end surface of one of the heat sinks and the lower end surface of the cold plate; located on the other side of the cold plate, a second gap is provided between the lower end surface of another heat sink and the upper end surface of the cold plate.

[0046] If the heat sink whose height changes with the force in Example 1 is used, then when any optical module is inserted into any one or two rows of optical module sockets, the corresponding optical module socket will be lifted up, and the second triangular prism and the third triangular prism of the corresponding heat sink will slide down toward the first triangular prism, and the gap will become smaller; when the optical module is pulled out, the second triangular prism and the third triangular prism will return to their original positions under the restoring force of the spring.

[0047] If the heat sink whose height changes with the force in the second embodiment is used, insert the second branch of the spring into the mounting hole on the first heat dissipation component before insertion. Because there is a mounting hole on the first heat dissipation component, the second heat dissipation component also has a mounting hole. If any optical module is inserted into any row or two rows of optical module sockets, the corresponding optical module socket will be lifted up, and the first heat dissipation component will slide down; when the optical module is pulled out, the first heat dissipation component will be reset under the restoring force of the spring. If you want to increase the adjustment height, you can set another mounting hole on the first heat dissipation component to connect another right-angled triangular prism in series, and so on to stack and connect multiple components in series. The specific number is subject to the actual height that needs to be adjusted.

[0048] If the heat sink whose height changes with the force in the third embodiment is used, in the natural state, the first heat dissipation component and the second heat dissipation component are stretched apart because of the elastic member with the arc-shaped portion. When any optical module is inserted into any row or two rows of optical module sockets, the corresponding optical module socket will be lifted up, and the gap will become smaller; when the optical module is pulled out, the first heat dissipation component will be reset under the restoring force of the spring.
