[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1-5As shown, this embodiment provides a heat dissipation platform, which includes a mounting frame 100, a mounting platform 200, a shock absorber 300, and a cooling fan 400. The mounting frame 100 has a support arm 131 on each of its opposite sides along a first direction, extending towards each other. The mounting platform 200 includes a first panel 210 and a second panel 220 arranged vertically at intervals along a second direction. The first panel 210 and the second panel 220 are detachably connected, forming an integral structure after connection. A heat dissipation channel is formed between the adjacent end faces of the first panel 210 and the second panel 220, and both the heat dissipation channel and the support arms 131 extend along a third direction. The opposing end faces of the first panel 210 and the second panel 220 are used to mount optoelectronic components. In this embodiment, both the first panel 210 and the second panel 220 have mounting surfaces for mounting optoelectronic components (i.e., the opposing end faces of the first panel 210 and the second panel 220), which is beneficial for improving integration. The aforementioned first direction is... Figure 1 The X-axis direction shown is the second direction. Figure 1 The Z-axis direction shown is the third direction. Figure 1 The Y-axis direction is shown in the figure.

[0047] One end of the shock absorber 300 is mounted on the support arm 131, and the other end is connected to the first panel 210. For example, the shock absorber 300 can be a rubber column. A cooling fan 400 is mounted on the mounting bracket 100 and located on the adjacent side of the support arm 131. The cooling fan 400 and the heat dissipation channel are directly opposite each other along a third direction. When the optoelectronic components mounted on the first panel 210 and / or the second panel 220 require rapid heat dissipation, the cooling fan 400 can be turned on to force-cool the heat dissipation channel. The airflow carries away the heat from the first panel 210 and the second panel 220, thereby rapidly cooling the optoelectronic components and achieving good temperature control. Simultaneously, the shock absorber 300 between the support arm 131 and the first panel 210 absorbs the vibration generated by the rotation of the cooling fan 400, preventing interference with the optoelectronic components and resulting in superior performance.

[0048] As an alternative solution, see Figure 3In this embodiment, the mounting bracket 100 includes a front panel 110, a rear panel 120, and two side panels 130. The front panel 110 and the rear panel 120 are opposite each other along a third direction, and the two side panels 130 are opposite each other along a first direction. A support arm 131 is provided on each side of the two side panels 130 that are close to each other, and the two support arms 131 are close to each other along the first direction. The length direction of both the side panels 130 and the support arms 131 is along the third direction. A cooling fan 400 is disposed on the rear panel 120. Exemplarily, to accelerate air turbulence, multiple cooling fans 400 can be provided on the rear panel 120. This embodiment uses three cooling fans 400 as an example. In other embodiments, depending on the dimensions of the mounting bracket 100 along the first direction, other numbers of cooling fans 400 can be provided, arranged as needed.

[0049] Furthermore, two support arms 131 spaced apart along the first direction are used to support the two ends of the first panel 210 along the first direction, so that the force on the first panel 210 along the first direction is more balanced. Each support arm 131 may also be provided with multiple shock absorbers 300, which are spaced apart along three directions on the support arm 131, so that the force on the first panel 210 along the third direction is more balanced.

[0050] See section 2 for further details. Figures 6-8In this embodiment, the heat dissipation platform includes a first connector 510, a first through hole 1311 on the support arm 131, and a first threaded hole 310 at one end of the shock absorber 300. The first connector 510 passes through the first through hole 1311 and is threaded into the first threaded hole 310, thereby fixing the shock absorber 300 to the support arm 131. Further, the heat dissipation platform includes a second connector 520, a second through hole 211 on the first panel 210, and a second threaded hole 320 at the other end of the shock absorber 300. The second connector 520 passes through the second through hole 211 and is threaded into the second threaded hole 320, thereby fixing the shock absorber 300 to the first panel 210. By adopting the above assembly method, the heat dissipation platform is easy to assemble and disassemble, and the assembly efficiency is high. In addition, the mounting bracket 100 and the mounting platform 200 are connected only through the shock absorber 300. After the shock absorber 300 is assembled with the first panel 210 and the support arm 131, there is a first assembly gap between the end of the first panel 210 along the first direction and the end face of the side panel 130 facing the first panel 210, and there is a second assembly gap between the end of the second panel 220 along the first direction and the end face of the side panel 130 facing the second panel 220. This avoids interference between the first panel 210, the second panel 220 and the side panel 130, effectively alleviating the problem of vibration generated when the cooling fan 400 rotates being transmitted to the mounting platform 200 (including the first panel 210 and the second panel 220). The shock absorption effect is good, which helps to ensure that the optoelectronic components installed on the first panel 210 and the second panel 220 remain stable during operation and have excellent performance.

[0051] Optionally, the end face of the support arm 131 facing the first panel 210 is provided with a plurality of limiting grooves 1312, each corresponding to a shock absorber 300, and the first through hole 1311 is located at the bottom of the limiting groove 1312. The end of the shock absorber 300 near the support arm 131 is embedded in the limiting groove 1312. This facilitates the installation and positioning of the shock absorber 300 and the support arm 131, making assembly easy and achieving high assembly accuracy.

[0052] Furthermore, in some alternative solutions, a limiting structure can be provided on the support arm 131 and / or the first panel 210. The limiting structure can be a support rib, a protrusion, etc., to prevent excessive displacement of the installation platform 200 during transportation, which could damage or break the shock absorber 300. Of course, the limiting structure can also be provided on the side panel 130 and / or the second panel 220, which will not be described in detail here.

[0053] See also Figure 6 , Figure 9 and Figure 10The heat dissipation platform includes a third connector 530. One of the first panel 210 and the second panel 220 has a third through hole 221, and the other of the first panel 210 and the second panel 220 has a third threaded hole 212. The third connector 530 passes through the third through hole 221 and is threaded into the third threaded hole 212, thereby fixing the first panel 210 and the second panel 220 together. After the third connector 530 is assembled with the first panel 210 and the second panel 220, the mounting platform 200 forms a whole. The mounting platform 200 can be assembled with the shock absorber 300 on the mounting bracket 100 after assembly. In this embodiment, the first panel 210 has a third threaded hole 212, and the second panel 220 has a third through hole 221. By adopting the above assembly method, the first panel 210 and the second panel 220 are easy to process and convenient to assemble and disassemble.

[0054] Furthermore, one of the first panel 210 and the second panel 220 is provided with a plurality of heat dissipation fins 213 arranged at intervals along a first direction. All the heat dissipation fins 213 extend towards the other of the first panel 210 and the second panel 220, dividing the heat dissipation channel into multiple sub-channels 230. The arrangement of the heat dissipation fins 213 facilitates faster heat dissipation and improves heat dissipation efficiency. In this embodiment, the example given is that the first panel 210 is provided with a plurality of heat dissipation fins 213 arranged at intervals along the first direction, and all the heat dissipation fins 213 extend towards the second panel 220.

[0055] See also Figure 1 and Figure 3 Each of the two side panels 130 has a raised rib 132 on one side facing away from each other. The raised rib 132 can improve the structural strength of the side panel 130, and the rigidity of the side panel 130 after assembly with the front panel 110 and the rear panel 120 is higher, and the mounting bracket 100 is more secure and less prone to deformation.

[0056] Furthermore, the front panel 110 is provided with an interface fixing hole 111 and a ventilation hole 112. The interface fixing hole 111 facilitates the lead-out of the connector of the optoelectronic component, and the ventilation hole 112 is directly opposite to the heat dissipation channel in the third direction. The rear panel 120 is provided with a mounting hole 121, and the cooling fan 400 is directly opposite to the mounting hole 121 in the third direction. Thus, the airflow generated by the cooling fan 400 when it is working can flow through the mounting hole 121, the heat dissipation channel and the ventilation hole 112 in sequence, thereby quickly removing the heat from the first panel 210 and the second panel 220.

[0057] This embodiment also provides a semiconductor laser, see [link / reference] Figure 11The semiconductor laser includes optoelectronic components and the aforementioned heat dissipation platform. The optoelectronic components are arranged on the first panel 210 and / or the second panel 220 of the heat dissipation platform. By employing this heat dissipation platform, the cooling fan 400 on the mounting bracket 100 can promptly dissipate the heat conducted by the optoelectronic components to the first panel 210 and / or the second panel 220, resulting in excellent heat dissipation. Simultaneously, the cooling fan 400 is connected to the mounting bracket 100, while the optoelectronic components are connected to the mounting platform 200. The mounting bracket 100 and the mounting platform 200 are connected by a vibration damping component 300, effectively isolating the cooling fan 400 from vibrations from the external environment. This heat dissipation platform is suitable for optoelectronic components that require vibration damping and heat dissipation. For example, this heat dissipation platform can also be applied to other types of fiber lasers.

[0058] Furthermore, the semiconductor laser also includes an upper shell 600 and a lower shell 700. Both the upper shell 600 and the lower shell 700 are connected to the mounting bracket 100 of the heat dissipation platform. The upper shell 600, the lower shell 700, and the mounting bracket 100 together form an accommodating space, which is used to place the mounting platform 200 of the heat dissipation platform.

[0059] Optionally, the semiconductor laser includes a fourth connector (not shown in the figure). A fourth through hole 1301 is provided at one end of the side panel 130 along a third direction. The fourth through hole 1301 is located on the side of the rib 132 along a second direction. A corresponding fourth threaded hole 113 is provided on the front panel 110. The fourth connector passes through the fourth through hole 1301 and is threaded into the fourth threaded hole 113, thus fixing the side panel 130 to the front panel 110. Alternatively, the semiconductor laser includes a fifth connector (not shown in the figure). A fourth through hole 1301 is also provided at the other end of the side panel 130 along a third direction. The fourth through hole 1301 is located on the side of the rib 132 along a second direction. A corresponding fifth threaded hole 122 is provided on the rear panel 120. The fifth connector passes through the fourth through hole 1301 and is threaded into the fifth threaded hole 122, thus fixing the side panel 130 to the rear panel 120.

[0060] Furthermore, the semiconductor laser includes a sixth connector (not shown in the figure). Both the upper shell 600 and the lower shell 700 are U-shaped. The upper shell 600 has a first fixing hole 610 on its opposite wall surface along a first direction. The side panel 130 has a fifth through hole 1302 corresponding to the first fixing hole 610. The front panel 110 has a sixth threaded hole 114 corresponding to the fifth through hole 1302. The sixth connector passes through the first fixing hole 610 and the fifth through hole 1302 and then threadedly engages with the sixth threaded hole 114, thus fixing the upper shell 600, side panel 130, and front panel 110. The semiconductor laser includes a seventh connector (not shown in the figure). The upper shell 600 has a second fixing hole 620 on its opposite wall surface along a second direction. The front panel 110 has a seventh threaded hole 115 corresponding to the second fixing hole 620. The seventh connector passes through the second fixing hole 620 and then threadedly engages with the seventh threaded hole 115, thus fixing the upper shell 600 and the front panel 110. The first connector 510, the second connector 520, the third connector 530, the fourth connector, the fifth connector, the sixth connector, and the seventh connector mentioned above can be bolts. The assembly method between the rear panel 120, the side panel 130, and the upper shell 600 is the same as the assembly method between the front panel 110, the side panel 130, and the upper shell 600, and will not be described again here.

[0061] Furthermore, the lower shell 700 has a third fixing hole 710 on the wall surface opposite to it in the first direction, and a fourth fixing hole 720 on the wall surface opposite to the second panel 220 in the second direction. The assembly method between the front panel 110, the rear panel 120, the side panel 130, and the lower shell 700 is the same as the assembly method between the front panel 110, the rear panel 120, the side panel 130, and the upper shell 600, and will not be described again here.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
