Description

Technical Field

[0001] This utility model relates to the field of multi-layer flow guiding structures for air-cooled laser devices, and specifically to a multi-layer flow guiding structure for air-cooled laser devices. Background Technology

[0002] With the rapid development of laser technology, the output power of lasers continues to rise, and the breakthrough from kilowatts to megawatts has become a core requirement for industrial applications. As a key component ensuring the stable operation of laser devices, the performance of the heat dissipation system directly determines the power threshold, output stability, and lifespan of the laser.

[0003] In existing technologies, laser devices generate a lot of heat during use. Common DC-type heat dissipation structures rely solely on increasing the power of the fan to improve heat dissipation. However, the heat dissipation effect is significantly reduced during the standby period of the laser device. These different heat dissipation requirements mean that the heat dissipation structure of the laser device can adapt to different heat dissipation needs.

[0004] Therefore, it is necessary to invent a multi-layer flow guiding structure for an air-cooled laser device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer airflow guiding structure for air-cooled laser devices. By setting a stable and closed airflow channel that fits the arc surface of the base, it can ensure efficient heat dissipation during high-power operation, and also meet the low-power heat dissipation requirements and avoid heat accumulation during standby by reverse airflow, and perform dust removal. This can solve the problem in the prior art that the heat dissipation requirements of laser devices are different under different working conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer flow guiding structure for a wind-cooled laser device, comprising... The outer casing has a mounting bracket fixedly connected to its inner wall. A circuit board is mounted on the upper surface of the mounting bracket. A laser generator is fixedly connected to the inner wall of the mounting bracket. A closed air blowing assembly is provided on the inner wall of the outer casing. A multi-layer flow guiding assembly is used to connect and place a mounting bracket. The multi-layer flow guiding assembly includes a base, which is fixedly connected to the inner wall of the outer shell. A placement groove is formed on the upper surface of the base. A heat dissipation plate is fixedly connected to the outer wall of the base. A flow guiding plate is fixedly connected to the lower surface of the base. A partition plate is fixedly connected to the lower surface of the base. A flow guiding block is fixedly connected to the outer wall of the partition plate.

[0007] Preferably, the enclosed air blowing assembly includes a mounting base, which is fixedly connected to the inner wall of the housing. A side baffle is fixedly connected to the upper surface of the mounting base, and a fan is fixedly connected to the outer wall of the side baffle.

[0008] Preferably, the fan is connected through and fixedly to the inner wall of the housing, the side baffle is fixedly connected to the inner wall of the housing, and the side baffle is fixedly connected to the outer wall of the heat sink.

[0009] Preferably, the mounting bracket is disposed on the inner wall of the placement groove, the guide plate is arc-shaped, and the guide plate is fixedly connected to the upper surface of the mounting base.

[0010] Preferably, the side baffle is arc-shaped, and multiple sets of side baffles are provided, with the multiple sets of side baffles arranged symmetrically about the center line of the base as the axis of symmetry.

[0011] Preferably, a dust cover is fixedly connected to the outer wall of the outer casing.

[0012] Preferably, the heat sink is provided in multiple sets, and the multiple sets of heat sink arrays are arranged on the outer wall of the base, and the heat sink is fixedly connected to the inner wall of the side baffle.

[0013] Preferably, the partition plate is cross-shaped, the base is rhomboid in shape, and the outer wall is a concave arc-shaped surface.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model achieves airflow path switching between working and standby states by rotating the fan in the closed air blowing assembly in both directions. When working, it forms a stable closed air duct that fits the arc surface of the base, ensuring efficient heat dissipation during high-power operation. When in standby mode, the reverse airflow can not only meet the heat dissipation requirements of low power consumption and avoid heat accumulation, but also remove internal dust, thus solving the problem that the existing DC-type airflow structure cannot adapt to different heat dissipation requirements.

[0015] 2. This utility model, through the synergistic design of multi-layered airflow guiding components, uses a cross-shaped partition plate to extend the contact time between the airflow and the base, an array-type heat sink to increase the heat exchange area, and an arc-shaped airflow guide plate and guide block to optimize airflow stability and reduce turbulence. Combined with a closed air duct to prevent airflow leakage, it achieves efficient heat dissipation without simply increasing fan power, ensuring the output stability and lifespan of the laser.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figure 1 - Figure 3 The diagram shows a multi-layer flow guiding structure for a wind-cooled laser device, including an outer shell 1; The inner wall of the outer casing 1 is fixedly connected to a mounting bracket 2 for mounting other components. A circuit board 3 is mounted on the upper surface of the mounting bracket 2. A laser generator 4 is fixedly connected to the inner wall of the mounting bracket 2. Both the circuit board 3 and the laser generator 4 are existing structures and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. The inner wall of the outer casing 1 is provided with a closed air blowing assembly 6 for sealing the multi-layer flow guiding assembly 5. The multi-layer flow guide assembly 5 is used to connect and place the mounting bracket 2 to guide airflow and dissipate heat for components such as the laser generator 4. The multi-layer flow guide assembly 5 includes a base 51 for heat conduction. The base 51 is fixedly connected to the inner wall of the outer shell 1 and supported and fixed by the outer shell 1. The upper surface of the base 51 has a placement groove 52 for placing other components such as the circuit board 3. The outer wall of the base 51 is fixedly connected to a heat dissipation plate 53 for guiding airflow and dissipating heat. The lower surface of the base 51 is fixedly connected to a flow guide plate 54. The lower surface of the base 51 is fixedly connected to a partition plate 55 for separating the direction of gas flow. The outer wall of the partition plate 55 is fixedly connected to a flow guide block 56 for making the gas flow more stable.

[0021] like Figure 1 - Figure 3As shown, the enclosed air blowing assembly 6 includes a mounting base 61 for mounting and connecting other components. The mounting base 61 is fixedly connected to the inner wall of the outer shell 1 and is supported and fixed by the outer shell 1. A side baffle 62 is fixedly connected to the upper surface of the mounting base 61. The side baffle 62 blocks the heat sink 53, allowing the airflow to flow along the concave arc surface of the base 51. A fan 63 is fixedly connected to the outer wall of the side baffle 62. The fan 63 passes through and is fixedly connected to the inner wall of the outer shell 1 to supply air to the multi-layer air guiding assembly 5. The side baffle 62 is fixedly connected to the inner wall of the outer shell 1. The side baffle 62 is arc-shaped. When working, the incoming air enters from the side and exits from the front and rear sides. In the standby state, the air can be reversed to enter from the front and rear sides and exit from the left and right sides. Multiple sets of side baffles 62 are provided. The multiple sets of side baffles 62 are symmetrically arranged with the center line of the base 51 as the axis of symmetry, blocking the space between the arc surface of the base 51 and the heat sink 53.

[0022] like Figure 1 - Figure 3 As shown, the mounting bracket 2 is set on the inner wall of the placement slot 52. The guide plate 54 is arc-shaped to disperse and guide the airflow. The guide plate 54 is fixedly connected to the upper surface of the mounting base 61. The mounting base 61 seals the space between the guide plate 54 and the base 51. The outer wall of the outer shell 1 is fixedly connected to a dust cover 7. Multiple sets of heat dissipation plates 53 are arranged in an array on the outer wall of the base 51. The heat dissipation plates 53 dissipate heat and guide airflow from the side wall of the base 51. The heat dissipation plates 53 are fixedly connected to the inner wall of the side baffle 62 and sealed by the side baffle 62. The partition plate 55 is cross-shaped to separate the bottom space and allow the airflow to flow in a J-shape to ensure the heat dissipation effect of the airflow contacting the base 51. The base 51 is rhomboid in shape and the outer wall is a concave arc surface.

[0023] The working principle of this utility model is as follows: Under normal operating conditions, the fan 63 in the enclosed air blowing assembly 6 starts, generating forced airflow. The airflow enters from the side of the outer casing 1, is guided by the arc shape of the side baffle 62, and is constrained and flows against the concave arc surface of the base 51. Because multiple sets of side baffles 62 are symmetrically arranged and enclose the space between the base 51 and the heat sink 53, the airflow is restricted within the preset channel, forming a stable flow path. The airflow first impacts the side wall of the base 51 and undergoes preliminary heat exchange through the array of heat sinks 53. The heat sinks 53 effectively increase the heat dissipation area, dispersing the heat conducted from the circuit board 3 and laser generator 4 from the base 51 into the airflow. Subsequently, the airflow is dispersed under the arc shape of the guide plate 54 and enters the bottom space separated by the partition plate 55. The cross-shaped design of the partition plate 55 divides the airflow path into multiple independent areas, forcing the airflow to flow in a J-shape. This effectively prolongs the contact time between the airflow and the lower surface of the base 51, enhancing the heat conduction efficiency. The airflow guide block 56 further stabilizes the airflow, reduces turbulence, and ensures that the airflow evenly covers the entire heat dissipation surface of the base 51. Finally, the airflow is discharged from the front and rear sides of the outer casing 1, completing the entire heat dissipation process. In standby mode, the fan 63 can run in reverse. At this time, the airflow enters from the front and rear sides of the outer casing 1, and after being guided by the airflow guide plate 54 and the partition plate 55, it is discharged from the left and right sides. This reverse flow mode adapts to the heat dissipation requirements under low power consumption, avoids heat accumulation, and helps to remove dust that may accumulate through reverse airflow. Throughout the process, the mounting base 61 and the side baffle 62 together form a closed air duct to prevent airflow leakage and ensure that all airflow is used for effective heat dissipation. The base 51, as the core of heat conduction, continuously discharges the heat generated by the circuit board 3 and the laser generator 4 carried on the mounting bracket 2 in the placement slot 52, and achieves efficient cooling through heat dissipation plate 53 and airflow exchange. The dust cover 7 provides initial protection against external dust and maintains the long-term stable operation of internal components.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
