[0002] With the rapid development of the laser industry, laser technology has become widely used in industries such as industry, communications, healthcare, and military. A laser is a device that emits laser light. It typically consists of a housing and an optoelectronic module, which is housed within the housing. During operation, the optoelectronic module generates significant heat, which can affect the laser's performance.

[0003] As a type of laser, fiber laser has the advantages of low cost, low threshold, good stability, easy operation, high light conversion efficiency, and compact structure, and is therefore widely used. The seed source of the fiber laser is usually provided with a nonlinear polarization rotation mode-locking module. This module integrates a variety of optical functional components, including a PDI polarization-dependent isolator, a PBS polarization splitter, a WDM wavelength division multiplexer, a monitoring port, and a polarization controller. In order to improve production costs and operating efficiency, the seed source of the existing ultrafast fiber laser further reduces the volume of the above-mentioned integrated module, achieving a highly integrated device. However, for the highly integrated module structure, the traditional heat dissipation method cannot achieve a balance between improving heat dissipation capacity and saving space, and the heat dissipation effect is not ideal. Utility Model Content

[0004] In response to the deficiencies in the above-mentioned prior art, the utility model provides a seed source heat dissipation housing and a seed source for a fiber laser. By optimizing the seed source housing structure, the heat dissipation capacity of the fiber laser seed source is effectively improved, while taking up almost no additional space, which is conducive to reducing the overall volume of the seed source and realizing equipment integration.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] As a further implementation method, a BUMP heat dissipation convex point is provided on the bottom surface of the shell, and the BUMP heat dissipation convex point is in contact with the mesh boss, further increasing the contact area between the shell and the air and promoting heat dissipation.

[0010] As a further implementation, the turbofan hole corresponds to the position and shape of the internal cooling fan, and a plurality of turbofan holes are provided to improve the heat dissipation capacity.

[0011] As a further implementation, a plurality of first U-shaped heat dissipation holes are provided, and the plurality of first U-shaped heat dissipation holes are evenly distributed on the top surface and side walls of the shell, effectively increasing convection between the shell and the outside air and accelerating heat dissipation.

[0012] As a further implementation, the depth of the turbofan hole does not exceed 1 / 4 of the width of the shell, which does not affect the structural strength of the seed source.

[0013] As a further implementation, the top surface and side surfaces of the cover plate are provided with second U-shaped heat dissipation holes corresponding to the first U-shaped heat dissipation holes, so as to further improve the heat dissipation capacity.

[0014] As a further implementation, the width of the cover plate is smaller than the width of the shell, and the cover plate is arranged on a side of the shell away from the mesh-shaped boss.

[0015] As a further implementation method, the shell and cover are made of aluminum alloy, which has the advantages of low density, high structural strength, good thermal conductivity, and is conducive to heat dissipation.

[0016] As a further implementation method, the shell and the cover plate are processed with rounded corners on their circumferences, which not only increases the contact area with the air and is beneficial to heat dissipation, but also makes it easier to process the hole seat for installation.

[0017] A seed source for an optical fiber laser comprises a housing, wherein the housing adopts any one of the above-mentioned heat dissipation housings for a seed source for an optical fiber laser.

[0018] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0019] 1. The utility model realizes active heat dissipation and accelerates air convection through the turbofan hole on the back of the shell, which corresponds to the cooling fan installed in the shell. At the same time, multiple first U-shaped heat dissipation holes are arranged around to further increase convection, effectively improving the heat dissipation performance of the seed source shell structure and ensuring the stability of the seed source and its internal optical module.

[0020] 2. The utility model sets a second U-shaped heat dissipation hole on the cover plate, which can realize automatic convection heat dissipation with the outside air, realizes the combination of active heat dissipation and automatic heat dissipation, and further improves the heat dissipation efficiency and effect.

[0033] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Example 1

[0036] In a typical embodiment of the present application, a heat dissipation housing for a seed source of a fiber laser is provided, such as Figure 1-10 As shown, the device comprises a housing 1 and a cover plate 2, which is mounted on the outside of the housing from one side. A turbofan hole 3 is provided on the back of the housing 1. First U-shaped heat dissipation holes 4 are provided on the top and side surfaces of the housing 1 to increase convection with the outside air and improve heat dissipation performance. Specifically, the first U-shaped heat dissipation holes are strip-shaped and distributed around the circumference of the housing to promote air circulation and achieve efficient heat dissipation.

[0037] like Figure 1 、 2 As shown, the cover plate 2 covers the front side of the housing 1 and surrounds the housing. A turbofan hole 3 is provided on the back of the housing 1, recessed into the wall to a certain depth, corresponding to the installation position of the internal cooling fan, to accelerate convection during fan heat dissipation and improve heat dissipation efficiency. In addition, the shape of the turbofan hole 3 is adapted to the shape of the cooling fan, and multiple turbofan holes can be provided to improve heat dissipation capacity. Specifically, as shown in FIG. Figure 2 、 5 As shown, in this embodiment, two turbofan holes are opened in parallel on the back of the shell, which cooperate with the heat dissipation fan to effectively improve the heat dissipation efficiency.

[0038] In order to achieve effective heat dissipation of the optical elements inside the seed source, a plurality of penetrating first U-shaped heat dissipation holes 4 are provided on the top and side surfaces of the housing 1. Figure 4 As shown, the first U-shaped heat dissipation hole 4 is a mesh design, which can increase convection with the outside air. When the heat dissipation fan is powered on, the hot air can be discharged to the outside of the seed source through the first U-shaped heat dissipation hole 4 around the shell 1 to achieve active heat dissipation.

[0039] In this embodiment, Figure 1-4 As shown in Figures 6-7, a plurality of mesh-shaped bosses 5 are provided outwardly on the back of the shell 1.

[0041] In this embodiment, the depth of the turbofan hole does not exceed 1 / 4 of the width of the shell, which does not affect the structural strength of the seed source. In a preferred embodiment, a similar turbofan hole 3 is opened on the front surface of the shell at a position corresponding to the cooling fan, such as Figure 5 As shown, further accelerating heat dissipation.

[0042] like Figure 6-7 As shown, there are multiple first U-shaped heat dissipation holes 4 on the shell, and the multiple first U-shaped heat dissipation holes 4 are arranged side by side in a row and evenly distributed on the top surface and side walls of the shell 1, which effectively increases the convection between the shell and the outside air and accelerates heat dissipation.

[0043] To further improve the heat dissipation performance, such as Figure 9-10 As shown, the top and side surfaces of the cover plate 2 are provided with second U-shaped heat dissipation holes 6 corresponding to the first U-shaped heat dissipation holes. A plurality of second heat dissipation holes 6 are evenly distributed side by side, which can realize automatic convection heat dissipation with the outside air and cooperate with the shell 1 to maximize the heat dissipation of the seed source.

[0044] like Figure 1 、 3 As shown in FIG. 4 , in this embodiment, the width of the cover plate 2 is smaller than the width of the housing 1 , and the cover plate 2 is arranged on a side of the housing 1 away from the mesh-shaped boss 5 .

[0045] In this embodiment 1, Figure 1 As shown, the rounded corners on the sides of the shell and cover plate increase the contact area with the air, which is beneficial to heat dissipation, and also makes it easier to process the hole seat for installation.

[0046] In this embodiment, the shell and cover are made of aluminum alloy 7075, which has the advantages of low density, high structural strength, good thermal conductivity, and is conducive to heat dissipation.

[0049] It should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations.
