When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] The laser module is provided with a laser generator, which generates a large amount of heat when in operation. However, the laser module in the related art uses air cooling to dissipate heat from the laser generator, which has a poor heat dissipation effect.

[0058] In order to improve the heat dissipation effect of the laser module 10 , the present invention provides a laser module 10 .

[0059] Please refer to Figures 1 to 5 In one embodiment of the present utility model, the laser module 10 includes a mounting base 100 and a plurality of laser generators 400. The mounting base 100 has a first end and a second end. A first heat dissipation channel 110 is formed in the mounting base 100. The first end is provided with a second heat dissipation channel 120, and the second end is provided with a third heat dissipation channel 130. One end of the first heat dissipation channel 110 is connected to the second heat dissipation channel 120, and the other end of the first heat dissipation channel 110 is connected to the third heat dissipation channel 130; a plurality of laser generators 400 are provided, some of the plurality of laser generators 400 are provided at the first end, and some are provided at the second end; wherein the second heat dissipation channel 120 and the third heat dissipation channel 130 both flow through at least one laser generator 400.

[0060] The mounting base 100 can be a base for mounting a circuit board and a laser optical component. The laser optical component includes a laser generator 400 and other optical elements. The mounting base 100 can be formed with a mounting cavity for mounting the laser optical component. The laser generator 400 will generate a large amount of heat when in operation. By forming a first heat dissipation channel 110 in the mounting base 100, the laser generator 400 arranged on the mounting base 100 can be cooled, thereby preventing the temperature of the laser generator 400 from being too high.

[0061] Specifically, the two ends of the first heat dissipation channel 110 can respectively penetrate the first surface 100a and the second surface 100b of the mounting base 100, which are opposite or adjacent to each other. This facilitates processing of the first heat dissipation channel 110 and facilitates communication between the first heat dissipation channel 110 and other heat dissipation channels. The first heat dissipation channel 110 can be linear, zigzag, or curved. For the convenience of processing, the first heat dissipation channel 110 provided in the mounting base 100 usually includes a plurality of straight-through pipes that are interconnected. For example, the first heat dissipation channel 110 only includes one straight-through sub-channel, and the first heat dissipation channel 110 is linear; or, the first heat dissipation channel 110 includes two straight-through sub-channels that intersect with each other, and at least one end of each of the two straight-through sub-channels that intersect with each other passes through the surface of the mounting base 100, thereby facilitating processing; or, the first heat dissipation channel 110 includes three or more straight-through sub-channels, and these straight-through sub-channels can be connected in sequence, or these straight-through sub-channels can cross to form a network structure, etc. It should be noted that at least one end of each of these straight-through sub-channels also needs to pass through the surface of the mounting base 100, thereby facilitating the processing of each straight-through sub-channel. It is understandable that when the first heat dissipation channel 110 includes more straight sub-channels, or the length or span of the first heat dissipation channel 110 is longer, the area it covers is larger, thereby further improving the heat dissipation effect of the laser device.

[0062] The plurality of laser generators 400 are partially located at the first end and partially located at the second end, thereby making the arrangement of the plurality of laser generators 400 more rational and improving the space utilization on the mounting base 100. The mounting base 100 has a first end and a second end. The first end is provided with at least a portion of the second heat dissipation channel 120, and the second end is provided with at least a portion of the third heat dissipation channel 130. One end of the first heat dissipation channel 110 is connected to the second heat dissipation channel 120, and the other end of the first heat dissipation channel 110 is connected to the third heat dissipation channel 130. This allows the coolant to flow sequentially through the second heat dissipation channel 120 at the first end of the mounting base 100, the first heat dissipation channel 110 located between the first and second ends, and the third heat dissipation channel 130 flowing through the second end, creating a 3D flow path for the coolant. This facilitates heat dissipation of the laser optical assembly disposed within the mounting base 100 from multiple directions within the mounting base 100, thereby improving the heat dissipation effect.

[0063] In addition, the second heat dissipation channel 120 and the third heat dissipation channel 130 both flow through at least one laser generator 400. For example, if both the second heat dissipation channel 120 and the third heat dissipation channel 130 flow through one, two, three, four, or more, or all of the laser generators 400, the second heat dissipation channel 120 and the third heat dissipation channel 130 are both close to the at least one laser generator 400, thereby achieving a better heat dissipation effect for the laser generator 400. Specifically, the second heat dissipation channel 120 can be linear, zigzag, or curved, as long as it can ensure that the second heat dissipation channel 120 can flow through at least one laser generator 400. Similarly, the third heat dissipation channel 130 can be linear, zigzag, or curved, as long as it can ensure that the third heat dissipation channel 130 can flow through at least one laser generator 400. It should be noted that the second heat dissipation channel 120 and the third heat dissipation channel 130 both flow through at least one laser generator 400, which means that the flow path of the second heat dissipation channel 120 and the third heat dissipation channel 130 passes through at least part of the periphery of the laser generator 400, rather than that the flow path passes through the laser generator 400.

[0064] The technical solution of the present invention is to form a first heat dissipation channel 110 in the mounting base 100, and the mounting base 100 has a first end and a second end. The first end is provided with at least a portion of the second heat dissipation channel 120, and the second end is provided with at least a portion of the third heat dissipation channel 130. One end of the first heat dissipation channel 110 is connected to the second heat dissipation channel 120, and the other end of the first heat dissipation channel 110 is connected to the third heat dissipation channel 130. In this way, the coolant can flow from the second heat dissipation channel 120 to the first heat dissipation channel 110, and then flow to the third heat dissipation channel 130 through the first heat dissipation channel 110, or the coolant can flow from the third heat dissipation channel 130 to the first heat dissipation channel 110, and then flow to the second heat dissipation channel 120 through the first heat dissipation channel 110. As a result, the mounting base 100 has heat dissipation channels at the first end, the second end, and between the two ends, so as to form a 3D heat dissipation channel, which greatly improves the heat dissipation effect. In addition, by arranging some of the multiple laser generators 400 at the first end and some at the second end, the second heat dissipation channel 120 and the third heat dissipation channel 130 both flow through at least one laser generator 400, so that the coolant can effectively and quickly dissipate heat for at least one laser generator 400 when flowing through the second heat dissipation channel 120, and the coolant can effectively and quickly dissipate heat for at least another laser generator 400 when flowing through the third heat dissipation channel 130, thereby improving the heat dissipation efficiency of the laser module.

[0065] In some embodiments, the first end and the second end are opposite or adjacent to each other. Figures 1 to 5As shown, the first end portion and the second end portion are opposite to each other in the first direction. Specifically, the laser generator 400 can be mounted on the mounting base 100 .

[0066] In some embodiments of the present invention, the laser module 10 further includes a first cover member 210 and a second cover member 220, the first end portion has a first surface 100a, the second end portion has a second surface 100b, the first cover member 210 and the second cover member 220 are respectively arranged on the first surface 100a and the second surface 100b, the mounting base 100 and the first cover member 210 form a second heat dissipation channel 120, and the mounting base 100 and the second cover member 220 form a third heat dissipation channel 130.

[0067] Specifically, in one example, the first cover 210 and the second cover 220 can be metal covers or corrosion-resistant plastic covers. The entire second heat dissipation channel 120 is disposed on the first surface 100a of the mounting base 100. Alternatively, a portion of the second heat dissipation channel 120 can be disposed on the first cover 210, and a portion can be disposed on the first surface 100a of the mounting base 100. When the first cover 210 is sealed and attached to the first surface 100a of the mounting base 100, half of the second heat dissipation channel 120 on the first cover 210 and half of the second heat dissipation channel 120 on the first surface 100a of the mounting base 100 together form a complete second heat dissipation channel 120. Similarly, the third heat dissipation channel 130 can be arranged on the second surface 100b of the mounting base 100; or half of it can be arranged on the second cover member 220 and the other half on the second surface 100b of the mounting base 100. When the second cover member 220 is sealed and fitted with the second surface 100b of the mounting base 100, half of the third heat dissipation channel 130 on the second cover member 220 and half of the third heat dissipation channel 130 on the second surface 100b of the mounting base 100 together form an integral third heat dissipation channel 130.

[0068] The first cover member 210 and the second cover member 220 are respectively sealed against the first surface 100a and the second surface 100b of the mounting base 100, thereby improving the sealing between the two and reducing the risk of the coolant in the second heat dissipation channel 120 leaking out of the gap between the cover member 200 and the mounting base 100. When the two are sealed against each other, a sealing strip can be used for sealing, or a sealing ring can be clamped between the two. When the first cover member 210 is detachably connected to the mounting base 100, screw connection, clamping or other detachable connection methods can be used. When the second cover member 220 is detachably connected to the mounting base 100, screw connection, clamping or other detachable connection methods can be used, as long as it is easy to remove the first cover member 210 and the second cover member 220 from the mounting base 100.

[0069] Furthermore, the first cover member 210 and the second cover member 220 are detachably connected to the first surface 100a and the second surface 100b of the mounting base 100, respectively. By detachably connecting the first cover member 210 and the second cover member 220 to the first surface 100a and the second surface 100b of the mounting base 100, respectively, it is convenient to remove the first cover member 210 and the second cover member 220 and then machine the first heat dissipation channel 110, the second heat dissipation channel 120, and the third heat dissipation channel 130, thereby achieving the effect of forming 3D heat dissipation channels through machining. This, on the one hand, is more cost-effective and facilitates mass production compared to 3D printing, and on the other hand, it also improves the heat dissipation effect of the laser generator 400.

[0070] In order to facilitate the injection of coolant into the second heat dissipation channel 120, the first cover member 210 may also have a liquid inlet 211 connected to the outside world; in order to facilitate the coolant to flow out of the mounting base 100, the first cover member 210 or the second cover member 220 may have a liquid outlet 212, so that the heat dissipation channel in the mounting base 100 and the external cooling source form a circulation channel to ensure that the coolant in the first heat dissipation channel 110, the second heat dissipation channel 120 and the third heat dissipation channel 130 on the mounting base 100 can always effectively exchange heat with the laser generator 400 set on the mounting base 100, thereby improving the heat dissipation efficiency.

[0071] In one embodiment of the present invention, please refer to Figure 3 、 Figure 4 as well as Figure 10 The second heat dissipation channel 120 flows through the periphery of all the laser generators 400 provided at the first end.

[0072] By having the second heat dissipation channel 120 flow through the periphery of all the laser generators 400 at the first end, all the laser generators 400 disposed at the first end can be effectively cooled, thereby improving the heat dissipation efficiency of the laser generators 400 .

[0073] Specifically, when there are two rows of laser generators 400, to allow the second heat dissipation channels 120 to flow outside the periphery of all laser generators 400 at the first end, the second heat dissipation channels 120 may surround the matrix formed by all laser generators 400; alternatively, the second heat dissipation channels 120 may be S-shaped, or at least two S-shaped channels connected end to end, or E-shaped, or a shape similar to a "concave" character, so that part of the second heat dissipation channels 120 can flow through the area between two adjacent laser generators 400. When there are multiple rows of laser generators 400, the second heat dissipation channels 120 may be S-shaped, or at least two S-shaped channels connected end to end, or other irregular shapes, as long as the second heat dissipation channels 120 can flow outside the periphery of all laser generators 400 at the first end. When the second heat dissipation channel 120 flows outside the periphery of the laser generator 400, it may flow through only one side of the laser generator 400, or may flow through two adjacent sides of the laser generator 400, or may flow through multiple sides of the laser generator 400. For different laser generators 400, a portion of the second heat dissipation channel 120 may flow through one side of some of the laser generators 400, while another portion may flow through at least two sides of some of the laser generators 400.

[0074] In one embodiment of the present invention, please refer to Figure 3 、 Figure 4 as well as Figure 10 The second heat dissipation channel 120 is at least partially located between two adjacent laser generators 400 .

[0075] By locating at least part of the second heat dissipation channel 120 between two adjacent laser generators 400, this part of the second heat dissipation channel 120 can dissipate heat for two adjacent laser generators 400 at the same time, thereby improving the heat dissipation effect for the laser generator 400 at the first end.

[0076] In one embodiment of the present invention, please refer to Figure 3 、 Figure 4 as well as Figure 10 All the laser generators 400 provided at the first end are arranged in a matrix to form a first laser generator matrix, and the inlet 121 and the transfer port 122 of the second heat dissipation channel 120 are provided on the same side of the first laser generator matrix.

[0077] It should be noted that the inlet 121 refers to the port through which the second heat dissipation channel 120 communicates with the outside, and the adapter 122 refers to the port through which the second heat dissipation channel 120 communicates with the first heat dissipation channel 110. By locating the inlet 121 and adapter 122 of the second heat dissipation channel 120 on the same side of the first laser generator matrix, while ensuring that the second heat dissipation channel 120 can flow outside the periphery of all laser generators 400 located at the first end, the second heat dissipation channel 120 needs to extend from the side where the inlet 121 and adapter 122 are located to the side of the first laser generator matrix away from the inlet 121 and adapter 122 of the second heat dissipation channel 120. This can extend the path of the second heat dissipation channel 120 and improve the heat dissipation effect of the second heat dissipation channel 120 on the laser generators 400 located at the first end.

[0078] In one embodiment of the present invention, Figure 9 As shown, the third heat dissipation channel 130 flows through the periphery of all the laser generators 400 disposed at the second end.

[0079] By flowing the third heat dissipation channel 130 through the periphery of all the laser generators 400 at the second end, all the laser generators 400 disposed at the second end can be effectively cooled, thereby improving the heat dissipation efficiency of the laser generators 400.

[0080] Specifically, when there are two rows of laser generators 400, to allow the third heat dissipation channels 130 to flow outside the periphery of all laser generators 400 at the second end, the third heat dissipation channels 130 may surround the matrix formed by all laser generators 400. Alternatively, the third heat dissipation channels 130 may be S-shaped, or at least two S-shaped channels connected end to end, or E-shaped, or a shape similar to a "concave" shape, so that part of the third heat dissipation channels 130 can flow through the area between two adjacent laser generators 400. When there are multiple rows of laser generators 400, the third heat dissipation channels 130 may be S-shaped, or at least two S-shaped channels connected end to end, or E-shaped, or other irregular shapes, as long as the third heat dissipation channels 130 can flow outside the periphery of all laser generators 400 at the second end. When the third heat dissipation channel 130 flows outside the periphery of the laser generator 400, it may flow through only one side of the laser generator 400, or may flow through two adjacent sides of the laser generator 400, or may flow through multiple sides of the laser generator 400. For different laser generators 400, a portion of the third heat dissipation channel 130 may flow through one side of some of the laser generators 400, while another portion may flow through at least two sides of some of the laser generators 400.

[0081] In one embodiment of the present invention, the third heat dissipation channel 130 is at least partially located between two adjacent laser generators 400 .

[0082] By locating at least part of the third heat dissipation channel 130 between two adjacent laser generators 400, this part of the third heat dissipation channel 130 can dissipate heat for two adjacent laser generators 400 at the same time, thereby improving the heat dissipation effect for the laser generator 400 at the first end.

[0083] In one embodiment of the present invention, Figure 9 As shown, the multiple laser generators 400 provided at the second end are arranged in a matrix to form a second laser generator matrix; one end of the third heat dissipation channel 130 is located inside the second laser generator matrix, and the other end is located outside the second laser generator matrix.

[0084] By locating one end of the third heat dissipation channel 130 within the second laser generator matrix and the other end outside the second laser generator matrix, at least a portion of the third heat dissipation channel 130 can flow outside two adjacent laser generators 400. This allows this portion of the third heat dissipation channel 130 to simultaneously dissipate heat for at least two adjacent laser generators 400 located at the second end, thereby improving the heat dissipation effect for the laser generators 400 at the second end. Specifically, the third heat dissipation channel 130 can be E-shaped, S-shaped, G-shaped, or spiral-shaped, etc.

[0085] Please refer to Figure 5 and Figure 6 In one embodiment of the present invention, a first groove portion 121 a is defined on the inner wall surface of the second heat dissipation channel 120 .

[0086] By providing the inner wall surface of the second heat dissipation channel 120 with a first groove portion 121a, the surface area of the inner wall of the second heat dissipation channel 120 can be increased, thereby improving the heat dissipation capacity. Specifically, the first groove portion 121a can extend along the extension path of the second heat dissipation channel 120, and there can be one, two, or more first groove portions 121a.

[0087] Please refer to Figure 5 and Figure 7 In one embodiment of the present invention, a second groove portion 122 a is defined on the inner wall surface of the third heat dissipation channel 130 .

[0088] By providing the inner wall surface of the third heat dissipation channel 130 with a second groove portion 122a, the surface area of the inner wall of the third heat dissipation channel 130 can be increased, thereby improving the heat dissipation capacity. Specifically, the second groove portion 122a can extend along the extension path of the third heat dissipation channel 130, and one, two, or more second groove portions 122a can be provided.

[0089] Please refer to Figures 1 to 3 In some embodiments of the present invention, a first mounting cavity 100A and a second mounting cavity 100B are formed in the mounting base 100, and optical lenses are installed in the first mounting cavity 100A and the second mounting cavity 100B. An isolation portion 150 is provided between the first mounting cavity 100A and the second mounting cavity 100B, and the first heat dissipation channel 110 is provided in the isolation portion 150.

[0090] By separating the optical lens into the first mounting cavity 100A and the second mounting cavity 100B, and providing an isolation portion 150 between the first mounting cavity 100A and the second mounting cavity 100B, a dual-path light output effect can be achieved, thereby reducing the size of the laser module 10 in a single direction, and further reducing the volume of the laser module 10. It is understood that the light emitted by the laser generator 400 is used to direct the optical lens, and the laser is emitted to the laser module 10 through the optical lens. Therefore, some laser generators 400 can be arranged corresponding to the first mounting cavity 100A and direct light toward the optical lens in the first mounting cavity 100A; another portion of the laser generators 400 can be arranged corresponding to the second mounting cavity 100B and direct light toward the optical lens in the second mounting cavity 100B.

[0091] By disposing the first heat dissipation channel 110 in the isolation portion 150 , the first heat dissipation channel 110 can dissipate heat from the optical lenses in the first mounting cavity 100A and the second mounting cavity 100B simultaneously, thereby improving the heat dissipation efficiency of the laser module 10 .

[0092] Please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 10 as well as Figure 11 In one embodiment of the present invention, the first heat dissipation channel 110 includes a plurality of sub-channels, and the plurality of sub-channels include sub-channels extending along a first direction and sub-channels extending along a second direction, wherein the second direction is set at an angle to the first direction.

[0093] By providing multiple sub-channels, including sub-channels extending along the first direction and sub-channels extending along the second direction, the length of the first heat dissipation channel 110 can be longer and the coverage area can be larger, thereby improving the heat dissipation efficiency of the first heat dissipation channel 110.

[0094] Specifically, when the second direction is arranged at an angle to the first direction, the second direction and the first direction can be arranged perpendicularly, at an acute angle, or at an obtuse angle. Among the multiple sub-flow channels, at least one sub-flow channel can be provided that extends along the first direction, and at least one sub-flow channel can be provided that extends along the second direction. The sub-flow channels extending along the first direction and the sub-flow channels extending along the second direction can together form a mesh-like cross structure or a zigzag structure connected end to end.

[0095] Please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 10 as well as Figure 11 In one embodiment of the present invention, the first heat dissipation channel 110 includes a first sub-channel 110a, a second sub-channel 110b and a third sub-channel 110c; the first sub-channel 110a extends along the first direction and has an inlet 111 connected to the second heat dissipation channel 120, and the inlet 111 is close to one end of the mounting base 100 in the second direction; the second sub-channel 110b extends along the first direction and has an outlet 112 connected to the third heat dissipation channel 130; one end of the third sub-channel 110c is connected to the first sub-channel 110a, and the other end is connected to the second sub-channel 110b, and at least a portion of the third sub-channel 110c extends along the second direction, and the second direction is set at an angle to the first direction.

[0096] Since both the first sub-channel 110a and the second sub-channel 110b extend in the first direction, and the inlet of the first sub-channel 110a of the first heat dissipation channel 110 is close to one end of the mounting base 100 in the second direction, and the third sub-channel 110c extends in the second direction, the first heat dissipation channel 110 can not only cover a part of the mounting base 100 in the first direction, but also cover a part of the mounting base 100 in the second direction, thereby maximizing the coverage range of the first heat dissipation channel 110 and improving the heat dissipation efficiency of the first heat dissipation channel 110.

[0097] It should be noted that when one end of the third sub-channel 110c is connected to the first sub-channel 110a, it can mean that one end of the third sub-channel 110c is directly connected to the first sub-channel 110a, or it can mean that one end of the third sub-channel 110c is indirectly connected to the first sub-channel 110a. When the other end of the third sub-channel 110c is connected to the second sub-channel 110b, it can mean that the other end of the third sub-channel 110c is directly connected to the second sub-channel 110b, or it can mean that the other end of the third sub-channel 110c is indirectly connected to the second sub-channel 110b.

[0098] Specifically, the third heat dissipation channel 110c can be curved or straight. When the third heat dissipation channel 110c is curved, it can have two or more bends. It is understood that when the third heat dissipation channel 110c has more bends, the path of the third heat dissipation channel 110c is longer, and its heat dissipation effect is better.

[0099] Furthermore, the first heat dissipation channel 110 further includes a fourth sub-channel 110d and a fifth sub-channel 110e. The fourth sub-channel 110d extends along the second direction and communicates with the second sub-channel 110b. The fifth sub-channel 110e communicates with the third sub-channel 110c and the fourth sub-channel 110d.

[0100] Based on the aforementioned solution of the third sub-channel 110c extending along the second direction, in this embodiment, a fourth sub-channel 110d extending along the second direction is provided, and a fifth sub-channel 110e connects the third sub-channel 110c and the fourth sub-channel 110d. This creates a zigzag flow path between the first sub-channel 110a and the second sub-channel 110b, thereby increasing the flow path between the first sub-channel 110a and the second sub-channel 110b and further enhancing the heat dissipation effect of the first heat dissipation channel 110. The fifth sub-channel 110e can connect the third sub-channel 110c and the fourth sub-channel 110d at the same end or at different ends in the second direction.

[0101] Further, please refer to Figure 4 、 Figure 5 、 Figure 10 as well as Figure 11 The laser module 10 further includes a plug 300 . The first heat dissipation channel 110 has a through-opening 101 penetrating the mounting seat 100 . The plug 300 is installed at the through-opening 101 to seal the through-opening 101 .

[0102] It should be noted that the through-port 101 of the first heat dissipation channel 110 is a port of the first heat dissipation channel 110 that is different from the inlet 111 and the outlet 112 and that can penetrate the mounting base 100. By providing the through-port 101, it is easier to form the first heat dissipation channel 110 into a broken line shape through machining, thereby improving the heat dissipation capacity. By installing a plug 300 at the through-port 101, the risk of coolant in the first heat dissipation channel 110 flowing out of the through-port 101 can be reduced, thereby ensuring that the coolant can remain in the first heat dissipation channel 110 and exchange heat with the heat-generating components provided on the mounting base 100.

[0103] Specifically, based on the above-mentioned solution that the first heat dissipation channel 110 includes the third sub-channel 110c, at least one end of the third sub-channel 110c in the second direction penetrates the mounting seat 100 to form a through-opening 101; based on the above-mentioned solution that the first heat dissipation channel 110 includes the third sub-channel 110c, the fourth sub-channel 110d and the fifth sub-channel 110e, at least one end of the third sub-channel 110c, at least one end of the fourth sub-channel 110d and at least one end of the fifth sub-channel 110e penetrate the mounting seat 100 and form a through-opening 101.

[0104] Please refer to Figure 4 、 Figure 5 、 Figure 8 as well as Figure 9 In one embodiment of the present invention, a fourth heat dissipation channel 140 is further provided in the mounting base 100 . In the first direction, the fourth heat dissipation channel 140 passes through the mounting base 100 , and one end of the fourth heat dissipation channel 140 is connected to the third heat dissipation channel 130 .

[0105] By connecting one end of the fourth heat dissipation channel 140 to the third heat dissipation channel 130, and by extending the fourth heat dissipation channel 140 through the mounting base in the first direction, the cooling channel can be lengthened, thereby improving heat dissipation capacity. Specifically, the fourth heat dissipation channel 140 can extend through the end surface of the first end portion of the mounting base 100, thereby facilitating connection of the cooling source to the cooling channel's liquid inlet 211 and liquid outlet 212. Of course, in other examples, the fourth heat dissipation channel 140 can also extend through the end surface of the second end portion of the mounting base 100.

[0106] Based on the solution that the laser module 10 includes the first cover member 210 and the second cover member 220 , in one embodiment of the present application, the first cover member 210 and the second cover member 220 are circuit boards.

[0107] By configuring the first and second cover members 210 and 220 as circuit boards, the coolant in the second and third heat dissipation channels 120 and 130 can dissipate heat from the circuit boards. Furthermore, the circuit boards on the laser module 10 can be used to cover the second and third heat dissipation channels 120 and 130, eliminating the need for separate components and saving material costs.

[0108] Furthermore, the circuit board includes a substrate, and the substrate is an aluminum substrate or a copper substrate.

[0109] By setting the substrate of the circuit board to an aluminum substrate or a copper substrate, the heat dissipation efficiency of the second heat dissipation channel 120 and the third heat dissipation channel 130 can be further improved through the circuit board, thereby enhancing the heat dissipation effect.

[0110] Specifically, the circuit board also has a circuit. When the circuit board serves as the first cover member 210 , the circuit is arranged on the side of the substrate away from the second heat dissipation channel 120 ; when the circuit board serves as the second cover member 220 , the circuit is arranged on the side of the substrate away from the third heat dissipation channel 130 .

[0111] Further, please refer to Figure 3 、 Figure 6 as well as Figure 7The laser module 10 further includes a first sealing member 510 and a second sealing member 520. The first sealing member 510 is disposed between the first cover member 210 and the first surface 100a to seal the gap between the first cover member 210 and the first surface 100a; the second sealing member 520 is disposed between the second cover member 220 and the second surface 100b to seal the gap between the second cover member 220 and the second surface 100b.

[0112] By disposing the first sealing member 510 between the first cover member 210 and the first surface 100 a , the sealing between the first cover member 210 and the first surface 100 a can be improved, thereby reducing the risk of coolant flowing out of the second heat dissipating channel 120 .

[0113] By disposing the second sealing member 520 between the second cover member 220 and the second surface 100 b , the sealing between the second cover member 220 and the second surface 100 b can be improved, thereby reducing the risk of coolant flowing out of the third heat dissipating channel 130 .

[0114] The utility model also proposes a laser device, such as Figure 12 As shown, the laser device includes a laser module 10. The specific structure of the laser module 10 refers to the above embodiment. Since this laser device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0115] The laser device also includes a frame 20 and a moving component 30. The moving component 30 is mounted on the frame 20, and the laser module 10 is mounted on the moving component 30. The moving component 30 can drive the laser module 10 to achieve mobile processing. The moving component 30 can include one or more interconnected moving subcomponents, and the laser module 10 can be mounted on one of the moving subcomponents.
