A circulating ventilation heat dissipation mechanism for infrared ultrafast laser

Abstract

This utility model discloses a circulating ventilation and heat dissipation mechanism for an infrared ultrafast laser, including a protective component for sealing the laser and guiding airflow for heat dissipation. A transfer component is disposed inside the protective component, and a heat dissipation component for circulating coolant is disposed in the middle of the transfer component. A light-emitting component is disposed on top of the heat dissipation component. This circulating ventilation and heat dissipation mechanism for an infrared ultrafast laser utilizes an exhaust fan to draw air from the chamber, carrying away heat dissipated by the heat sink. Cool air entering from the air inlet flows along the gaps between the heat sinks, accelerating heat dissipation efficiency. The combination of air cooling and circulating coolant provides excellent cooling performance. A pulley system moves the laser element and its heat dissipation component from the center of the mounting bracket out of the chamber along a slide rail, reducing the difficulty of loading and unloading. A heat-conducting cylinder is inserted into the positioning hole, and then a fastening bolt is screwed in to secure the laser element. Different specifications of laser elements can be replaced as needed, expanding the range of applications.

Description

Technical Field

[0001] This utility model belongs to the field of computer hardware, and in particular relates to a circulating ventilation and heat dissipation mechanism for an infrared ultrafast laser. Background Technology

[0002] Infrared ultrafast lasers, as high-precision and high-efficiency light source devices, have wide applications in industrial processing, medical aesthetics, scientific research, and other fields. During operation, infrared ultrafast lasers generate a significant amount of heat, primarily from two sources: first, the quantum defect heating of the laser medium under high-energy pumping; and second, the heat generated by the absorption of laser energy by optical components. If this heat cannot be dissipated effectively and promptly, the internal temperature of the laser will rise, affecting its output performance and potentially damaging laser components.

[0003] In existing technologies, the heat dissipation mechanism for infrared ultrafast lasers does not have air cooling combined with coolant circulation for cooling, resulting in poor cooling effect; the laser components and their heat dissipation components are fixedly installed inside the enclosure, making maintenance difficult; the number of pump sources and beam collector specifications cannot be flexibly adjusted according to the application scenario, increasing energy consumption and limiting the scope of application. Utility Model Content

[0004] The purpose of this invention is to provide a circulating ventilation and heat dissipation mechanism for infrared ultrafast lasers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circulating ventilation and heat dissipation mechanism for an infrared ultrafast laser includes a protective component for sealing the laser and guiding airflow for heat dissipation. Inside the protective component is a transfer component, and in the middle of the transfer component is a heat dissipation component for circulating coolant for cooling. A light-emitting component is located on top of the heat dissipation component. The heat dissipation component includes a heat absorption box, with a water outlet pipe on one side. An impeller is located in the middle section of the water outlet pipe, and a water storage tank is located at the bottom end of the water outlet pipe. A heat dissipation box is located on the side of the water storage tank away from the impeller. Several heat dissipation fins are evenly distributed on the heat dissipation box. A circulating pump is installed on the side of the heat dissipation box away from the water storage tank. The circulating pump is connected to the heat absorption box via a return water pipe. Several positioning holes are evenly distributed on the heat absorption box.

[0007] Preferably, the protective component includes a housing with four symmetrically distributed slide rails on the inner wall of the housing. A cover is rotatably mounted on the front of the housing. A magnet is provided on the bottom of the housing near the cover. Four exhaust fans are symmetrically mounted on the cover. A wiring hole is provided on the side of the housing away from the cover. An air inlet is provided below the wiring hole. Dust covers are provided on both the exhaust fans and the air inlet.

[0008] Preferably, the transfer assembly includes a mounting frame with eight pulley sets symmetrically arranged on both sides, and a handle is installed on the side of the mounting frame near the box cover.

[0009] Preferably, the light-emitting component includes a pump source and a beam combiner, and heat-conducting cylinders are provided at the four bottom corners of the pump source and the beam combiner, with fastening bolts slidably inserted inside the heat-conducting cylinders.

[0010] Preferably, the extension direction of the heat sink is consistent with the flow direction of the coolant in the heat sink box.

[0011] Preferably, the slide rail has a U-shaped cross-section, and the pulley assembly is located inside the slide rail.

[0012] Preferably, the heat absorption box, the water storage tank, the heat dissipation box, and the circulating pump are all bolted to the mounting bracket.

[0013] Preferably, the heat-conducting cylinder is slidably connected to the positioning hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the exhaust fan draws air from the box to remove the heat dissipated by the heat sink, and the cold air entering from the air inlet flows along the gaps between the heat sinks to accelerate the heat dissipation efficiency. The combination of air cooling and coolant circulation provides a good cooling effect.

[0016] 2. In this utility model, the laser element and its heat dissipation assembly in the middle of the mounting frame are moved out of the box along the slide rail by the pulley, which reduces the difficulty of loading and unloading and facilitates the periodic maintenance work.

[0017] 3. In this utility model, the laser element is installed by inserting a heat-conducting cylinder into the positioning hole and then screwing in a fastening bolt. This provides good heat conduction while allowing for the replacement of laser elements of different specifications as needed, reducing energy consumption and expanding the scope of application.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 A circulating ventilation and heat dissipation mechanism for an infrared ultrafast laser includes a protective component 1 for sealing the laser and conducting airflow for heat dissipation, a transfer component 2 is provided inside the protective component 1, a heat dissipation component 3 for circulating coolant cooling is provided in the middle of the transfer component 2, and a light-emitting component 4 is provided on the top of the heat dissipation component 3.

[0026] In this embodiment: the protective component 1 includes a housing 101, with four slide rails 102 symmetrically distributed on the inner wall of the housing 101. A cover 103 is rotatably mounted on the front of the housing 101. A magnet 104 is provided on the bottom of the housing 101 near the cover 103. Four exhaust fans 105 are symmetrically mounted on the cover 103. A wiring hole 106 is provided on the side of the housing 101 away from the cover 103. An air inlet 107 is provided below the wiring hole 106. Dust covers 108 are provided on both the exhaust fans 105 and the air inlet 107. During the coolant circulation process, the cover 103 supports the exhaust fans 105 to draw air from the housing 101 and replenishes cold air from the air inlet 107, so that a unidirectional airflow is formed inside the housing 101. The airflow cools the laser components and flows along the gaps between the heat sinks 306 to carry away heat, thus cooling the coolant in the heat sink 305.

[0027] In this embodiment: the transfer component 2 includes a mounting frame 201, eight pulley groups 202 are symmetrically arranged on both sides of the mounting frame 201, and a handle 203 is installed on the side of the mounting frame 201 near the box cover 103. Pushing the handle 203 causes the mounting frame 201 to support the pulley groups 202 to slide along the slide rail 102, and the transfer component 2, heat dissipation component 3 and light-emitting component 4 enter the box 101.

[0028] In this embodiment: the heat dissipation component 3 includes a heat absorption box 301, a water outlet pipe 302 is provided on one side of the heat absorption box 301, an impeller 303 is provided in the middle section of the water outlet pipe 302, a water storage tank 304 is provided at the bottom end of the water outlet pipe 302, a heat dissipation box 305 is provided on the side of the water storage tank 304 away from the impeller 303, a plurality of heat dissipation fins 306 are evenly distributed on the heat dissipation box 305, a circulation pump 307 is installed on the side of the heat dissipation box 305 away from the water storage tank 304, the circulation pump 307 is connected to the heat absorption box 301 through a return water pipe 308, and a plurality of positioning holes 309 are evenly distributed on the heat absorption box 301. The circulating pump 307 delivers coolant to the heat absorption box 301. The coolant in the heat absorption box 301 absorbs heat from the laser components. The heated coolant flows through the impeller 303. If necessary, the blades of the impeller 303 can be visually inspected through the dust cover 108 to confirm whether the coolant is flowing normally. Then, the coolant collects in the water storage tank 304. The water storage tank 304 is set to hold more coolant to increase the total heat absorption of the heat dissipation component 3 in a short time. After the coolant reaches a uniform temperature, it flows into the heat dissipation box 305. After cooling down, the coolant returns to the circulating pump 307 to complete one heat dissipation cycle.

[0029] In this embodiment: the light-emitting component 4 includes a pump source 401 and a beam combiner 402. Each of the four bottom corners of the pump source 401 and the beam combiner 402 is provided with a heat-conducting cylinder 403. A fastening bolt 404 is slidably inserted into the heat-conducting cylinder 403. The bottom heat-conducting cylinder 403 of the pump source 401 and the beam combiner 402 is inserted into the positioning hole 309. After the fastening bolt 404 passes through the heat-conducting cylinder 403, the nut at the other end is tightened to fix the pump source 401 and the beam combiner 402 on the heat-absorbing box 301.

[0030] Working principle: Insert the bottom heat-conducting cylinder 403 of the pump source 401 and beam combiner 402 into the positioning hole 309. After the fastening bolt 404 passes through the heat-conducting cylinder 403, tighten the nut at the other end to fix the pump source 401 and beam combiner 402 onto the heat-absorbing box 301. Push the handle 203 to make the mounting bracket 201 support pulley group 202 slide along the slide rail 102, transferring the component 2, heat dissipation component 3, and light-emitting component 4 into the box 101. Close the box cover 103, and the magnet 104 fixes the box cover 103 by magnetic force. After the pump source 401 is powered on, the circulating pump 307 delivers coolant to the heat-absorbing box 301. The coolant in the heat-absorbing box 301 absorbs the heat of the laser components. The heated coolant flows through the impeller 303 and needs to be heated. The coolant can be visually inspected through the dust cover 108 to confirm whether the impeller 303 blades are flowing normally. Then the coolant gathers in the water tank 304. The water tank 304 is set to hold more coolant to increase the total heat absorption of the heat dissipation component 3 in a short time. After the coolant reaches a uniform temperature, it flows into the heat dissipation box 305. After cooling down, the coolant returns to the circulation pump 307 to complete a heat dissipation cycle. During the coolant circulation process, the box cover 103 supports the exhaust fan 105 to draw air from the box 101 and replenish cold air from the air inlet 107, so that a unidirectional airflow is formed inside the box 101. The airflow cools the laser components and flows along the gaps between the heat sinks 306 to carry away heat, thus cooling the coolant in the heat dissipation box 305.
