[0033] like Figures 1-6 As shown, this embodiment provides a modular air-cooled laser, including a cabinet 100, with ventilation ducts along a second direction. The first, second, and third directions are arranged at angles to each other. For example, the first direction is the Z-direction, the second direction is the front-back direction (X-direction), and the third direction is the left-right direction (Y-direction). For example, the cabinet 100 is a rectangular cabinet, with openings on both sides and the top along the second direction, allowing the internal space of the cabinet 100 to communicate with the outside. The openings on both sides of the cabinet 100 along the second direction have a first door 130 and a second door 140, and the opening at the top has a top cover 150. The first door 130 and the second door 140 each have ventilation holes 131. For example, the ventilation holes 131 on the first door 130 and the second door 140 may be arranged in a matrix of diamond-shaped holes. The ventilation holes 131 of the two doors and the internal space of the cabinet 100 form a ventilation duct, allowing for smoother airflow and ensuring adequate ventilation.
[0034] The modular air-cooled laser also includes an optical module 200, a pump module 300, and an electrical module 400.

The optical module 200, pump module 300, and electrical module 400 are stacked along a first direction within a cabinet 100. The first power supply 410 powers the pump source 310, which is optically connected to the optical component 210. For example, the optical component 210 includes optical elements, and the optical elements and the pump source 310 are optically connected via optical fibers; this is based on existing technology and will not be elaborated further.
[0035] The installation order of the optical module 200, pump module 300 and electrical module 400 is not limited. For example, the optical module 200, pump module 300 and electrical module 400 are stacked in order from bottom to top.
[0036] Cabinet 100 serves as the carrier, and the optical module 200, pump module 300, and electrical module 400 are stacked as three independent modules within cabinet 100. The optical module 200, pump module 300, and electrical module 400 follow a photoelectric separation design (optical-photoelectric-electric), allowing for quick installation and removal of each module individually. This independent module design improves versatility, maintainability, and reliability.
[0037] For example, the optical module 200, the pump module 300 and the electrical module 400 are all located on the ventilation duct, which is connected to the airflow path of the first heat dissipation component 220, the second heat dissipation component 320 and the third heat dissipation component 420.
[0038] The optical module 200 includes a first heat dissipation component 220 and an optical component 210. The optical module 200 is disposed on a ventilation duct. On the one hand, the ventilation duct is used for direct heat dissipation of the optical component 210; on the other hand, the first heat dissipation component 220 is used for heat dissipation of the optical component 210, and the ventilation duct is used for heat dissipation of the first heat dissipation component 220, thereby improving the heat dissipation effect of the first heat dissipation component 220, and thus improving the heat dissipation effect of the optical component 210. The ventilation duct is used for indirect heat dissipation of the optical component 210.
[0039] Similarly, the pump module 300 includes a pump source 310 and a second heat dissipation component 320. The pump module 300 is disposed on the ventilation duct. On the one hand, the ventilation duct is used for direct heat dissipation of the pump source 310; on the other hand, the second heat dissipation component 320 is used for heat dissipation of the pump source 310, and the ventilation duct is used for heat dissipation of the second heat dissipation component 320, which improves the heat dissipation effect of the second heat dissipation component 320, thereby improving the heat dissipation effect of the pump source 310. The ventilation duct is used for indirect heat dissipation of the pump source 310.
[0040] Similarly, the electrical module 400 includes a first power supply 410 and a third heat dissipation component 420. The first power supply 410 is disposed on the ventilation duct. On the one hand, the ventilation duct is used for direct heat dissipation of the first power supply 410; on the other hand, the third heat dissipation component 420 is used for heat dissipation of the first power supply 410, and the ventilation duct is used for heat dissipation of the third heat dissipation component 420, which improves the heat dissipation effect of the third heat dissipation component 420, thereby improving the heat dissipation effect of the first power supply 410. The ventilation duct is used for indirect heat dissipation of the first power supply 410.
[0041] Through the ventilation ducts on the cabinet 100, the optical module 200, pump module 300, and electrical module 400 are respectively equipped with a first heat dissipation component 220, a second heat dissipation component 320, and a third heat dissipation component 420 to cool the optical component 210, pump source 310, and first power supply 410 on their respective modules. The ventilation ducts can realize air cooling of the optical module 200, pump module 300, and electrical module 400, thereby meeting the heat dissipation requirements of modular air-cooled lasers and achieving the effect of water cooling. Moreover, the structure is simple and the cost is effectively reduced.
[0042] like Figures 2-5 As shown, in one embodiment, the first heat dissipation component 220, the second heat dissipation component 320, and the third heat dissipation component 420 all include a heat dissipation cavity 2. The optical component 210, the pump source 310, and the first power supply 410 are correspondingly installed in the heat dissipation cavities 2 of the first heat dissipation component 220, the second heat dissipation component 320, and the third heat dissipation component 420. Exemplarily, the heat dissipation cavity 2 is made of a thermally conductive metal material, such as aluminum. In the optical module 200, the optical component 210 is installed on the heat dissipation cavity 2 of the first heat dissipation component 220. After the optical component 210 generates heat, the heat is transferred to the heat dissipation cavity 2, achieving heat dissipation of the optical component 210. The ventilation channel is used for heat dissipation of the heat dissipation cavity 2, improving the heat dissipation effect of the heat dissipation cavity 2. In the pump module 300, the pump source 310 is installed on the heat dissipation cavity 2 of the second heat dissipation component 320. After the pump source 310 generates heat, the heat is transferred to the heat dissipation cavity 2, achieving heat dissipation of the pump source 310. In the electrical module 400, the first power supply 410 is installed in the heat dissipation cavity 2 of the third heat dissipation component 420. After the first power supply 410 generates heat, the heat is transferred to the heat dissipation cavity 2, thereby achieving heat dissipation of the first power supply 410.
[0043] Furthermore, the first heat dissipation assembly 220, the second heat dissipation assembly 320, and the third heat dissipation assembly 420 all include a housing 1, with a heat dissipation cavity 2 disposed within the housing 1. The housing 1 includes a first side plate 101 and a second side plate 102 disposed on both sides of the heat dissipation cavity 2 along the second direction (front-back direction). A fan 3 may be provided on one of the first side plate 101 and the second side plate 102, or both side plates 102 may be provided with a fan 3. The airflow direction within the housing 1 can be either from the first side plate 101 to the second side plate 102 or vice versa. The fan 3 can function as either a suction or blowing fan, without limitation. By providing the fan 3, the airflow speed is increased, which improves both the heat dissipation of the pump source 310, the first power supply 410, and the optical component 210 on the heat dissipation cavity 2, and the heat dissipation of the heat dissipation cavity 2 itself, thereby improving the heat dissipation effect on the pump source 310, the first power supply 410, and the optical component 210.
[0044] The housing 1 also includes a top plate 103 and a bottom plate 104 arranged along a first direction, respectively located on the upper and lower sides of the heat dissipation cavity 2. The housing 1 also includes two third side plates 105 arranged along a third direction, i.e., left and right sides, respectively located on the left and right sides of the heat dissipation cavity 2. The first side plate 101, second side plate 102, third side plate 105, top plate 103, and bottom plate 104 are fastened together with bolts for easy assembly and disassembly. The heat dissipation cavity 2, the first power supply 410, the pump source 310, and the optical components 210 are housed within the housing 1, providing protection and preventing structural damage from compression between different modules. Furthermore, the housing 1 is bolted to the cabinet 100, allowing the optical module 200, electrical module 400, and pump module 300 to be fixedly connected to the cabinet 100, preventing mutual interference between different modules during installation or disassembly. Furthermore, handles are provided on both the front and rear sides of the housing 1 in a second direction for gripping.
[0045] The heat dissipation cavity 2 is an extrusion molded cavity, which reduces costs. In one embodiment, the heat dissipation cavity 2 includes a cavity body 201 and heat dissipation fins 202 disposed inside the cavity body 201. The optical component 210, pump source 310 or first power supply 410 are disposed outside the cavity body 201 and dissipate heat through the heat dissipation fins 202, which has a good heat dissipation effect.
[0046] Optionally, the heat dissipation cavity 2 of the first heat dissipation component 220 is provided with a receiving groove, that is, the cavity body 201 is provided with a receiving groove, and the optical component 210 is installed in the receiving groove.
[0047] Optionally, the heat dissipation cavity 2 of the second heat dissipation component 320 is provided with mounting holes, that is, the cavity body 201 is provided with mounting holes, and the pump source 310 is mounted on the mounting holes by fasteners. The pump source 310 can be mounted on both sides of the heat dissipation cavity 2 of the second heat dissipation component 320 along the first direction. Depending on actual needs, the pump source 310 can be mounted on either side of the heat dissipation cavity 2. The pump module 300 includes at least one pump source 310, and the number of pump sources 310 can be expanded according to needs, improving applicability. The number of pump sources 310 is greater than or equal to 1 and less than or equal to 12, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12. For example, six pump sources 310 can be mounted on one side of the heat dissipation cavity 2. When there are no more than six pump sources 310, they are all mounted on the same side of the heat dissipation cavity 2.
[0048] like Figure 4 As shown, furthermore, the heat dissipation cavity 2 of the second heat dissipation component 320 is embedded with a heat-conducting pipe 4 or a heat-conducting plate, especially in areas of high local heat generation within the heat dissipation cavity 2. The heat-conducting pipe 4 or heat-conducting plate is made of a material with high thermal conductivity to quickly dissipate heat and avoid the problem of excessive and concentrated heat. For example, the heat-conducting pipe 4 is embedded in the cavity body 201, or it is embedded between the heat dissipation fins 202 and the cavity body 201. For example, the heat-conducting pipe 4 can be a solid or hollow metal tube or a heat pipe, where a heat pipe refers to a highly efficient heat transfer element that conducts heat using the phase change principle; existing technologies are readily available and will not be elaborated further. For example, the heat-conducting pipe 4 is a copper tube, which has a small heat sink volume and relatively low cost. For example, an 8mm diameter copper tube with a thermal conductivity of Qmax = 80W(mk) is used to resist gravity. The tube layout is combined with the actual processing limits and heat dissipation needs to ensure that the heat from the main heat source area is transferred to the low heat area and can be dissipated by air cooling.
[0049] like Figure 1 and Figure 6 As shown, the internal space of the cabinet 100 is divided into an upper storage compartment 110 and a lower storage compartment 120 along a first direction. The optical module 200, pump module 300, and electrical module 400 are located in the lower storage compartment 120, and the electrical control component 500 is located in the upper storage compartment 110. Exemplarily, the electrical control component 500 includes a circuit board 510, a second power supply 520, a third power supply 530, an air switch 540, and a filter 550, etc. Multiple circuit boards 510 are provided, respectively used for controlling the pump source 310 and the fan 3, etc., exemplarily... Figure 6The leftmost circuit board 510 controls the pump source 310. The three circuit boards 510 located above the middle control the fans 3 applied to the first heat dissipation assembly 220, the second heat dissipation assembly 320, and the third heat dissipation assembly 420, respectively. The second power supply 520 supplies power to the circuit boards 510, and the third power supply 530 supplies power to the fans 3. The electronic control component 500 is located in the upper housing 110, and the EMC design follows a strong and weak current separation design to prevent electromagnetic interference.
[0050] like Figure 1 As shown, the top cover 150, the first door 130, and the second door 140 are all operable and connectable to the cabinet 100. Opening the first door 130 and the second door 140 facilitates the disassembly and installation of the optical module 200, the pump module 300, and the electrical module 400, making maintenance and repair easier. Opening the top cover 150 facilitates the disassembly and installation of the electrical control component 500, making maintenance and repair easier, and providing greater convenience for power range adjustment, debugging, and maintenance.
[0051] Optionally, the top cover 150, the first door 130, and the second door 140 can all be detachably connected to the cabinet 100, such as by bolts. Optionally, the top cover 150, the first door 130, and the second door 140 are all hinged to the cabinet 100 at one end and locked to the cabinet 100 at the other end. When not needed, they are in a locked state, protecting the internal structure of the cabinet 100 and ensuring safety. When needed, they are in an unlocked state, facilitating quick disassembly, maintenance, repair, and debugging of the internal structure.
[0052] The first door body 130 is equipped with switches such as an emergency stop switch 170 and a main switch 160, while the second door body 140 is equipped with a power interface. The top cover 150 has winding posts 151 for winding armored cables, forming an armored cable placement area on the top cover 150. Optionally, the top cover 150 has four C-shaped posts to form the winding posts 151, preventing the armored cables from falling off.
[0053] The corners of the 100 rack are rounded to prevent sharp edges and avoid scratches.
