Description

Technical Field

[0001] The present invention relates to the field of laser technology, and in particular to a strip-shaped portable air-cooled laser. Background Art

[0002] Most traditional air-cooled lasers use a configuration design with a middle fin cold plate, air-cooling fans at the front / rear ends, and optoelectronic devices arranged on the upper and lower surfaces. However, in air-cooled lasers with this layout, the thermal power consumption and heating area of ​​each optoelectronic device are different, and their heat flux densities are very different, so their heat dissipation requirements are also different. This results in the traditional design only being able to provide heat dissipation according to the device with the highest heat dissipation requirement, resulting in a large waste of heat dissipation capacity and power consumption.

[0003] Moreover, in order to reduce the wind resistance of ventilation in traditional designs, the cold plate fins are designed to have the same gap and area, and cannot be optimized according to the actual heat dissipation requirements, resulting in a large weight redundancy. In addition, in order to maximize the use of fan air volume, the traditional design designs the fin cold plate to be as thick as the fan height. Since the left and right sides of the fin cold plate are not effectively used, the traditional design has a large size and weight redundancy, which is not conducive to transportation and carrying.

[0027] Many specific details are described in the following description to facilitate a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of this specification, so this specification is not limited to the specific implementation disclosed below.

[0029] It should be understood that although the terms first, second, etc. may be used to describe various information in one or more embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0030] First, the terms involved in one or more embodiments of this specification are explained.

[0031] Pump source: Excites the laser working material and pumps the activated particles from the ground state to a high energy level to achieve particle number inversion.

[0032] QBH: Fiber output device, which is a device that combines fiber fusion with quartz column and mechanical packaging to expand the fiber spot output and reduce the power density. It is commonly used for medium and high power continuous light, beam divergence output. It is used for metal cutting or welding processing.

[0033] In this specification, a strip-shaped portable air-cooled laser is provided, which is described in detail one by one in the following embodiments.

[0034] In actual usage scenarios, the two bottom surfaces of the cylindrical cold plate and the optical module cold plate can be any regular polygon or a circle. When the bottom surface shape is a regular polygon, the pump module is installed on each side of the regular polygon, and the shape of the fan is selected from the shape of the corresponding regular polygon bottom surface to achieve a compact arrangement of the various components of the long portable air-cooled laser; and when the bottom surface shape of the cylindrical cold plate and the optical module cold plate is circular, the pump module is connected to one side of the arc-shaped gasket, and the arc surface of the other side of the arc-shaped gasket is connected to the side of the cylindrical cold plate, and the arc surface of the arc-shaped gasket fits the arc of the side of the cylindrical cold plate, and the shape of the fan also fits the circular bottom surface of the cylindrical cold plate and the cylindrical cold plate. Similarly, the optical module cold plate also has a gasket to achieve fit with the optical module, and the shape of the fan also matches the ground of the optical module cold plate.

[0035] In conjunction with the accompanying drawings of the specification, the embodiment is described by using a regular quadrilateral columnar main cold plate, a regular quadrilateral columnar cold plate and an optical module cold plate, see Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of a strip-shaped portable air-cooled laser according to an embodiment of the present specification, wherein a fan 5 provides an air source in the air duct, except Figure 1 The fan 5 shown is directly connected to the cylindrical cold plate 1. In addition to being arranged in the front section of the air duct, the fan 5 can also be arranged in the middle section and the rear section of the air duct. Specifically, the arrangement in the middle section can be achieved by connecting one end of the fan 5 to the cylindrical cold plate 1 and the other end to the optical module cold plate, and the arrangement in the rear section can be achieved by connecting the fan 5 to the rear end of the optical module cold plate.

[0036] In addition, in addition to arranging a fan to provide an air source for the air duct, multiple fans can also be arranged in the air duct, and the positions of the multiple fans are the front section, middle section and rear section of the air duct mentioned above. However, in actual usage scenarios, the air source provided by the fan to the air duct will decrease as the wind propagation distance increases, thereby causing the heat dissipation capacity to decline. However, for the pump module 2 with higher heat dissipation requirements, the required wind flow intensity is higher. Therefore, arranging the fan 5 in the front section of the air duct is the best choice, and according to the actual heat dissipation situation, new fans are additionally installed in the middle section and the rear section of the air duct.

[0037] In the laser working scenario, the cylindrical cold plate 1 provides heat dissipation for the pump module 2, and the optical module cold plate provides heat dissipation for the optical module 3. The pump module 2 realizes the excitation of the laser working material, that is, generates laser. The optical module 3 amplifies the generated laser. The optical fiber output module 4 uses QBH to output the amplified laser, and the flexible optical fiber enables the optical fiber output module 4 to be movable, thereby improving the flexibility of use.

[0038] Specifically, the strip-shaped portable air-cooled laser comprises: a fan 5, a cylindrical cold plate 1, a pump module 2, an optical module 3, an optical module cold plate and an optical fiber output module 4;

[0039] The cylindrical cold plate 1 and the optical module cold plate constitute an air duct of a long strip portable air-cooled laser, the pump module 2 is arranged on the side of the cylindrical cold plate 1, the optical module 3 is arranged on any side of the optical module cold plate, and the fan 5 provides an air source for the air duct;

[0040] The pump module 2 generates pump light, which is amplified by the optical module 3 to obtain target laser light. The target laser light is transmitted to the optical fiber output module 4 through a flexible optical fiber for output.

[0041] like Figure 1As shown, the cylindrical cold plate 1 contains fins and is arranged at the front end of the air duct of the long strip portable air-cooled laser. The pump module 2 is arranged on the four sides of the cylindrical cold plate 1. The fan 5 is connected to one end of the cylindrical cold plate 1, and the other end of the cylindrical cold plate 1 is connected to the optical module cold plate.

[0042] Specifically, the fins disposed in the columnar cold plate 1 are made of different materials, so that the heat dissipation capacity of the columnar cold plate 1 is different. It should be noted that the material selection of the fins is determined by the actual use scenario and is not limited in this embodiment.

[0043] In addition, the columnar cold plate 1 and the optical module cold plate together form an air duct, that is, the wind generated by the fan 5 passes between the columnar cold plate 1 and the optical module cold plate, wherein the air supply direction of the fan 5 is consistent, such as Figure 1 As shown, the air supply direction A is from the cylindrical cold plate 1 to the optical module cold plate.

[0044] Based on this, the heat dissipation wind flow provided by the fan 5 is used to dissipate heat for the pump module 2 arranged on the four sides of the columnar cold plate 1. According to the above, as the distance traveled by the heat dissipation wind flow provided by the fan 5 in the air duct becomes longer, its wind flow density will decrease. In the actual use scenario, the heat flux density of the pump module 2 when working is much greater than the heat flux density of the optical module 3 when working. The attenuated wind flow in the air duct can meet the heat dissipation requirements of the optical module 3. In addition, for a laser equipped with multiple fans, except for the fan 5 arranged in the front section of the air duct, the output power of the remaining fans can be adjusted. For example, if a fan is installed in the middle section of the air duct, the output power of the fan in the middle section of the air duct can be 50% of that of the fan 5. The output power of the newly installed fan is adjusted to reduce the heat dissipation wind flow intensity provided by the newly installed fan. While ensuring that the heat dissipation requirements of the optical module can be met, the output power of the newly installed fan can also be avoided. Waste, thus achieving energy saving.

[0045] It should be noted that the fan 5, the cylindrical cold plate 1, the pump module 2, the optical module 3, the optical module cold plate and the optical fiber output module 4 can be connected by means of an outer frame, grooves, buckles, bolts, etc., while the cylindrical cold plate 1 and the optical module cold plate can be connected in sections or in an integral casting manner. The specific connection method is determined by the actual usage scenario and is not limited in this embodiment.

[0046] In summary, the present embodiment provides a strip-shaped portable air-cooled laser, in which the pump module 2 with the highest heat flux density is centrally arranged in the front section of the air duct, and the optical module 3 with low overall heat dissipation requirement is arranged in the rear section of the air duct, so that the thermal control capability of the fan is maximized, and the overall energy consumption requirement is reduced. Fins are arranged in the cylindrical cold plate 1 to meet the heat dissipation requirements. Since the size of the fin is similar to that of the fan, the fan air volume can be maximized, the overall design of the machine is the most compact, and the generation of excess weight is avoided, thereby improving the portability of the strip-shaped portable air-cooled laser.

[0047] In a specific implementation, the fins contained in the columnar cold plate 1 are evenly arranged along the four sides of the columnar cold plate 1 .

[0048] Among them, Figure 2 As shown in the schematic diagram of a cylindrical cold plate of a long strip portable air-cooled laser, the cylindrical cold plate 1 includes fins, and there are mounting points on the four sides of the shell of the cylindrical cold plate 1 for mounting the pump module 2. The mounting point can be a screw hole, and the pump module 2 is fixed to the cylindrical cold plate 1 by bolts, and the mounting point can also be a welding point, and the pump module 2 is connected to the cylindrical cold plate 1 by welding. The specific connection method is determined by the actual use scenario and is not limited in this embodiment.

[0049] In addition, if Figure 2 As shown, the end of the columnar cold plate 1 can be set to an irregular shape to facilitate the installation of the pump module 2. The specific shape of the end is determined by the actual use scenario and is not limited in this embodiment.

[0050] Based on this, for the consideration of maximizing heat dissipation efficiency, the pump module 2 is installed on the four sides of the cylindrical cold plate 1. At the same time, it is necessary to ensure that the pump modules 2 on each side have the same heat dissipation efficiency to achieve maximum heat dissipation and avoid excessive heat density at some points. Therefore, the fins are evenly arranged along the four sides of the cylindrical cold plate 1, such as Figure 3 A cross-sectional schematic diagram of a cylindrical cold plate of a long portable air-cooled laser is provided, and it is specified that the fins arranged in the cylindrical cold plate 1 do not have to cover the entire space. Since the center position is far away from the device that needs to dissipate heat, the center position has little effect on the heat dissipation of the device. In order to reduce the overall weight of the equipment, the fins are not arranged at the center position. It should be noted that the blank area left without fins at the center position can be square, circular, etc. The specific shape is determined by the actual usage scenario and is not limited in this embodiment.

[0051] In summary, by evenly arranging the fins along the four sides of the cylindrical cold plate 1, it is ensured that the pump modules 2 arranged on each side of the cylindrical cold plate 1 obtain the maximum heat dissipation effect, without having to design the output power of the fan 5 according to the pump module 2 in the area with the worst heat dissipation effect, thereby avoiding waste of heat dissipation capacity and power consumption.

[0052] In a specific implementation, fins are provided inside the optical module cold plate on the side adjacent to the optical module 3 .

[0053] Among them, Figure 4 As shown in the internal schematic diagram of an optical module cold plate of a long strip portable air-cooled laser, fins are arranged inside the side of the optical module cold plate adjacent to the optical module 3.

[0054] Based on this, by arranging fins inside the side of the square columnar cold plate adjacent to the optical module 3, the heat dissipation effect of the optical module 3 is improved, and the output power of the fan 5 is reduced to achieve heat dissipation of the optical module 3. In addition, the cold plate is only arranged on this side, which saves costs on the one hand and reduces the weight of the laser on the other hand, making it easier to carry, transport and use the laser.

[0055] In a specific implementation, the pump module 2 includes a pump source and a driving block, wherein the pump source is electrically connected to the driving block, and the driving block drives the pump source to excite the laser working material.

[0056] The driver block is a circuit device that drives the pump source through its internal circuit and controls the output power of the pump source, ensuring that the laser power output of the laser is controllable, and integrating the driver block with the pump source improves the electrical control effect and layout stability. In addition, in actual use scenarios, the heat flux density of the driver block is also high when it is working, and it is configured on the cylindrical cold plate 1, which is conducive to meeting the heat dissipation requirements of the driver block.

[0057] In a specific implementation, the long strip portable air-cooled laser includes a power-on module, and the power-on module is provided with a power-on button, through which the switching state of the circuit components contained in the long strip portable air-cooled laser is controlled, wherein the circuit components include the fan 5, the pump module 2, the optical module 3 and the optical fiber output module 4.

[0058] The power-on module can also be provided with a power-on button to control the long strip portable air-cooled laser, and the control range is the circuit components on the long strip portable air-cooled laser, that is, the components driven by the power supply, such as the fan 5, the pump module 2, the optical module 3, and the optical fiber output module 4, etc., which improves the controllability and practicality of the long strip portable air-cooled laser.

[0059] In a specific implementation, the power-on module includes a fan power control circuit. In response to a received fan power adjustment instruction, the fan power control circuit adjusts the voltage and current input of the fan 5 to achieve output power control of the fan 5 .

[0060] Among them, the fan power adjustment instruction can be generated by the user's operation on related controls, such as buttons, knobs, touch screens, etc. The specific control type is determined by the actual usage scenario and is not limited in this embodiment.

[0061] In addition, the fan power adjustment instruction can be generated based on the temperature sensor set at the preset point of the long strip portable air-cooled laser. For example, the temperature sensor collects the temperature data of the pump module 2. When the temperature is higher than the high temperature threshold, a fan power adjustment instruction for increasing the output power of the fan 5 is generated to avoid damage to the pump module 2 due to high temperature; when the temperature is lower than the low temperature threshold, a fan power adjustment instruction for reducing the output power of the fan 5 is generated to save power resources. If the temperature sensor collects the temperature data of the optical module 3, a fan power adjustment instruction for adjusting the fan 5 will also be generated based on the temperature data. It should be noted that the setting position of the temperature sensor generates different fan power types based on different temperature data, which is determined according to the actual usage scenario and is not limited in this embodiment.

[0062] In summary, the output power of the fan 5 is controlled by the fan power control circuit, which ensures the heat dissipation effect and prevents excessive power consumption. In addition, the heat dissipation effect can be controlled according to the actual needs of the user, ensuring flexibility of use.

[0063] In a specific implementation, the fan 5 can be replaced by a fan array consisting of n fans.

[0064] To ensure uniform heat dissipation of the pump module 2 , the cylindrical cold plate 1 is configured to be in the same square shape as the fan 5 . To ensure effective use of space, the size of the fan 5 should fit the cylindrical cold plate 1 as closely as possible.

[0065] Based on this, the fan array composed of n fans has a length and width dimension approximately 1:1, and the specific number of fans selected can be 4, 9, ..., m. 2 , where m is a positive integer and n=m 2 , meeting the requirement of fitting with the columnar cold plate 1, and the fan array can be configured with each fan having different output powers, so that the heat dissipation airflow in the air duct is not uniformly distributed in space. At this time, the direction and distribution of the fins inside the columnar cold plate 1 can be set according to the distribution of the heat dissipation airflow to ensure that the heat dissipation efficiency of the four sides of the columnar cold plate 1 is consistent.

[0066] Based on this, by replacing fan 5 with a fan array consisting of n fans, the heat dissipation controllability of the long strip portable air-cooled laser is improved, and the production and manufacturing of the long strip portable air-cooled laser is made more flexible, meeting more different usage requirements. In addition, if the bottom surface shapes of the columnar main cold plate and the columnar secondary cold plate are other regular polygons, such as regular triangles, a fan array with an outer contour shape that is the same as the bottom surface shape of the columnar main cold plate and the columnar secondary cold plate can be formed by 4 fans with regular triangle shapes.

[0067] In a specific implementation, the elongated portable air-cooled laser includes a DC conversion module, which adjusts the power supply voltage of the elongated portable air-cooled laser and supplies power to the circuit devices included in the elongated portable air-cooled laser according to the adjusted power supply voltage, wherein the circuit devices include the fan 5, the pump module 2, the optical module 3 and the optical fiber output module 4.

[0068] Based on this, the voltage of the power supply is adjusted through the DC conversion module so that the adjusted voltage meets the rated voltage of each circuit component, thereby providing power to each circuit component.

[0069] In summary, the heat dissipation effect of a strip-shaped portable air-cooled laser provided by the present application in an actual working scenario has been tested. Under the same air volume and heat generation conditions, the maximum temperature of the design scheme of the present application is 2°C-10°C lower than that of the traditional design scheme, and it has good heat dissipation. In addition, through the overall thermal control configuration layout design and the cylindrical cold plate 1 design related to the laser pump module 2, the heat dissipation capacity is improved while the power loss is reduced, and the overall volume and weight of the equipment are reduced, which is convenient for the use and movement of the equipment.

[0070] In addition, in addition to the above-mentioned long strip portable air-cooled laser, the bottom surfaces of the cylindrical cold plate and the optical module cold plate are set in the form of regular polygons, the bottom surfaces of the cylindrical cold plate and the optical module cold plate can also be set in the form of circles, such as Figure 5 As shown in the cylindrical structure diagram of a long strip portable air-cooled laser, it is also composed of a cylindrical cold plate, a pump module, an optical module, an optical module cold plate, an optical fiber output module, a fan, etc. In order to maximize the heat dissipation of the pump module by the cylindrical cold plate, the pump modules should be arranged at the same spacing on the side of the cylindrical cold plate to avoid heat enrichment caused by different spacing between pump modules and excessive heat at some points. It should be noted that Figure 5 It is a schematic diagram, and the number of pump modules is not limited to 4, and can be arranged according to actual usage. This embodiment does not limit the number of arranged pump modules.

[0071] Furthermore, for a long portable air-cooled laser with a circular cylindrical cold plate, the fins in the cylindrical cold plate are arranged as follows: Figure 6 As shown in the cross-sectional diagram of a cylindrical cold plate of a long strip portable air-cooled laser, the heat dissipation fins should be arranged evenly to avoid uneven heat dissipation and heat enrichment. In addition, for the long strip portable air-cooled laser with a circular cylindrical cold plate, the form of the optical module cold plate is as follows: Figure 7 As shown in the schematic diagram of a cylindrical structure cold plate of an optical module of a long portable air-cooled laser, fins are arranged adjacent to the optical module, which does not affect the actual heat dissipation effect while saving costs and reducing weight.
