Description

Technical Field

[0001] The present invention relates to the technical field of laser devices, and in particular, to a pump source. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The semiconductor laser pump source has been developing towards high brightness and high power. Since the pump source continuously generates heat during operation, a corresponding heat dissipation device is required to dissipate the heat. The heat dissipation device is generally divided into a water-cooled type and an air-cooled type. Due to the large volume, many structures and possible water leakage of the water-cooled radiator, the air-cooled radiator is more preferably used for heat dissipation. However, the air-cooled radiator has the following deficiencies when in use: 1. The traditional semiconductor pump source is installed on the metal tube shell base, and the heat exchange end of the radiator contacts the metal tube shell, so that the heat generating end does not directly contact the radiator, thus affecting the heat dissipation efficiency; 2. When the air-cooled radiator is in use, the air flow blown by the fan passes through each heat conduction tube and fin. When the air flow blows to the first half of the heat conduction tube and fin, it will carry the heat at that place through the second half, which will affect the heat dissipation efficiency of the second half; 3. The air flow direction is fixed. When the air flow blows to the second half of each heat conduction tube and fin, since it is blocked by the heat conduction tubes and fins in the first half, the heat dissipation efficiency is also affected. Therefore, a pump source with a corresponding heat dissipation structure is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a pump source aiming at the above deficiencies at present, so as to achieve comprehensive and efficient heat dissipation for the heat generating part of the pump source.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: A pump source, comprising:

[0006] A pump source component, which includes a module assembly and a tail fiber. The module assembly is used to generate laser and emit the laser to the tail fiber;

[0007] An encapsulation component, which includes a housing and a radiator. The pump source component is arranged at the heat exchange end of the radiator. The radiator is used to dissipate heat from the pump source component. The housing cooperates with the radiator to form an encapsulation shell for encapsulating the pump source component;

[0008] An air guiding component, which is arranged on the encapsulation component and is used to guide the air flow generated by the radiator to the heat dissipation end of the radiator in an inclined direction.

[0009] Further, the radiator is an air-cooled radiator, which includes a mounting plate, heat conduction tubes and fins arranged on one side of the mounting plate, and a cooling fan with an output end facing the heat conduction tubes and fins;

[0010] The pump source component is arranged on the side of the mounting plate away from the heat conduction pipe, and the heat generated by the pump source component will be transferred to the mounting plate.

[0011] The heat conduction pipe is used to transfer the heat at the mounting plate to the fin.

[0012] The fin is used to diffuse the heat at the heat conduction pipe.

[0013] The cooling fan is used to blow away the heat at the heat conduction pipe and the fin.

[0014] Further, the air guiding assembly is arranged at the bottom of the radiator, and its air inlet end is on the same side as the air inlet end of the corresponding fin of the radiator. When the cooling fan is working, the air flow can pass through the fin and the air inlet end of the air guiding assembly at the same time.

[0015] Further, the air guiding assembly includes a housing arranged at the bottom of the fin. A flow dividing part is arranged on the housing. The flow dividing part can guide the air flow entering the housing into multiple strands and make them blow to the side of the fin away from the cooling fan at different inclination angles.

[0016] Further, the flow dividing part includes a flow dividing plate. At least two inclined diversion grooves are formed on the flow dividing plate. One side of each diversion groove is communicated with the outside of the housing and is used to guide the air flow blown out by the cooling fan to enter.

[0017] The housing includes a first assembly plate and a second assembly plate. The flow dividing plate is arranged between the first assembly plate and the second assembly plate. At least two air outlet openings are formed on the first assembly plate. Each air outlet opening is located at the top of the side of the fin away from the cooling fan and is communicated with the side of the corresponding diversion groove away from the cooling fan. The diversion groove can guide the air flow entering it to blow upward to the side of the fin away from the cooling fan.

[0018] Further, a diversion sleeve is arranged in each corresponding diversion groove of the flow dividing plate. The diversion sleeve is in a pyramid shape, is hollow inside, and both sides of the diversion sleeve are open. The side with a larger diameter faces the air outlet opening.

[0019] Further, the diversion sleeve is detachably arranged on the second assembly plate.

[0020] The beneficial effects of the present invention are embodied in:

[0021] In the present invention, the pump source component is directly in contact with the heat exchange end of the radiator, and the housing and the radiator directly form a packaging shell to package the pump source component. Therefore, the heat generated by the pump source component during operation will be directly transferred to the radiator and dissipated by it. This method eliminates the metal shell, which can improve its heat dissipation performance on the basis of cost savings for practical use.

[0022] In the present invention, through the arrangement of the air guiding component, it can guide the cooling air flow to directly cool the pump source component while allowing part of the air flow to enter the air guiding component. The air guiding component will divide it into multiple strands, and make the multiple strands of air flow blow to the side of the radiator away from the air source at different inclined angles. Thus, when the radiator draws out the heat of the pump source component, it can comprehensively and evenly guide it outside the radiator, thereby further improving the heat dissipation efficiency.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-4 , the present invention discloses a pump source, which includes a pump source component 1. The pump source component 1 includes a module assembly 11 and an optical fiber pigtail 12. Among them, the module assembly 11 includes two rows of staggered COSs, large and small reflectors, a polarization beam combiner, a red light module, a beam expander and collimator lens group, and a SAC. When in use, it can generate laser light and emit the laser light to the optical fiber pigtail 12. And this pump source component 1 belongs to the common knowledge in the art, so the specific structural composition and working principle thereof will not be described in detail herein.

[0039] In one embodiment, the device further includes a packaging component 2. The packaging component 2 includes a housing 21 and a radiator 22. Among them, the pump source component 1 is arranged at the heat exchange end of the radiator 22. The radiator 22 is used to dissipate heat from the pump source component 1. At the same time, the housing 21 cooperates with the radiator 22 to form a packaging shell for packaging the pump source component 1. A gas guiding component 3 is also arranged on the packaging component 2, which is used to guide the airflow generated by the radiator 22 to the heat dissipation end of the radiator 22 in an inclined direction.

[0040] In specific implementation, the pump source component 1 is directly in contact with the heat exchange end of the radiator 22, and the housing 21 and the radiator 22 directly form a packaging shell to package the pump source component 1. Therefore, the heat generated by the pump source component 1 during operation will be directly transferred to the radiator 22 and dissipated by it. This method eliminates the metal tube shell, can improve its heat dissipation performance on the basis of cost savings, and is convenient for actual use.

[0041] In addition, through the setting of the gas guiding component 3, it can guide the cooling airflow to directly dissipate heat from the pump source component 1, and at the same time, part of the airflow enters the gas guiding component 3. The gas guiding component 3 will divide it into multiple strands, and make the multiple strands of airflow blow to the side of the radiator 22 away from the air source at different inclined angles. Thus, when the radiator 22 draws out the heat of the pump source component 1, it can comprehensively and evenly guide it out of the radiator 22, thereby further improving the heat dissipation efficiency.

[0042] In one embodiment, the radiator 22 is an air-cooled radiator, which includes a mounting plate 221, heat pipes 222 and fins 223 mounted on one side of the mounting plate 221, and a cooling fan (not shown in the figure) with an output end facing the heat pipes 222 and the fins 223. After the cooling fan is powered on, it immediately starts working and guides the air flow to blow to the fins 223.

[0043] In a specific implementation, the pump source component 1 is mounted on the side of the mounting plate 221 away from the heat pipes 222. When the pump source component 1 is working, the heat generated will be directly transferred to the mounting plate 221. At this time, the heat pipes 222 will transfer the heat at the mounting plate 221 to the fins 223. The fins 223 will then dissipate the heat at the heat pipes 222 and cooperate with the cooling fan to blow away the heat at the heat pipes 222 and the fins 223.

[0044] In one embodiment, the air guide assembly 3 is arranged at the bottom of the radiator 22, and its air inlet end is on the same side as the air inlet end of the corresponding fins 223 of the radiator 22.

[0045] In a specific implementation, when the cooling fan is working, the air flow can pass through the fins 223 and the air inlet end of the air guide assembly 3 at the same time, so that a part of the air flow passes through the fins 223 and takes away the heat, and at the same time, another part of the air flow enters the air guide assembly 3 and is guided by the air guide assembly 3 to be divided into multiple strands and blown obliquely to the side of the fins 223 away from the cooling fan.

[0046] In one embodiment, the air guide assembly 3 includes a housing 31 mounted at the bottom of the fins 223, and a flow splitting part 32 is arranged on the housing 31.

[0047] In a specific implementation, the flow splitting part 32 can guide the air flow entering the housing 31 into multiple strands and make them blow to the side of the fins 223 away from the cooling fan at different inclination angles.

[0048] In one embodiment, the flow splitting part 32 includes a flow splitting plate 321, and at least two inclined diversion grooves 322 are formed on the flow splitting plate 321. One side of each diversion groove 322 is communicated with the outside of the housing 31 and is used to guide the air flow blown out by the cooling fan to enter; the housing 31 includes a first assembly plate 311 and a second assembly plate 312, and the flow splitting plate 321 is mounted between the first assembly plate 311 and the second assembly plate 312. At least two air outlet openings 313 are formed on the first assembly plate 311. Each air outlet opening 313 is located at the top of the side of the fins 223 away from the cooling fan, and each of them is communicated with the side of the corresponding diversion groove 322 away from the cooling fan. The diversion grooves 322 can guide the air flow entering them to blow upward to the side of the fins 223 away from the cooling fan.

[0049] In specific implementation, when the cooling fan is working, part of the air flow enters the corresponding diversion grooves 322 of the diversion plate 321. Each diversion groove 322 divides the air flow into multiple strands, and makes them blow towards the air outlet 313 at different inclination angles. Finally, it passes through each air outlet 313 and blows upwards towards the side of the fin 223 away from the cooling fan, so that the heat at each part of the fin 223 can be blown away.

[0050] In one embodiment, a diversion sleeve 33 is provided in each corresponding diversion groove 322 of the diversion plate 321. The diversion sleeve 33 is in a pyramid shape, with a hollow interior, and both sides of the diversion sleeve 33 are open, and the side with a larger diameter faces the air outlet 313.

[0051] With such a design, when the air flow passes through the diversion sleeve 33, it can expand the passing range, so as to further increase the flow range of the side of the fin 223 away from the cooling fan, which is convenient for actual use.

[0052] In one embodiment, the diversion sleeve 33 is detachably installed on the second assembly plate 312, and this installation method can adopt the way of bolt fixation.

[0053] With such a design, after the staff removes the second assembly plate 312, the dust on the diversion sleeve 33 can be effectively replaced or cleaned, and at the same time, it is also convenient to clean the inside of the diversion plate 321.

[0054] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then the directional indications are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0055] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then the descriptions of "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0056] In addition, "a plurality of" means two or more.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
