[0041] like Figures 1 to 9 As shown, the present invention proposes a high-efficiency heat dissipation management method for a lath crystal, comprising a base 1 and a cover plate 2 covered on the base 1, the base 1 comprising a shell 11, the shell 11 is divided into heat dissipation chambers 1, 2 and 3 in sequence, a temperature alarm 114 is installed in the heat dissipation chamber 2, the heat dissipation chambers 1 and 3 are respectively arranged on both sides of the heat dissipation chamber 2 and are connected to each other, a circulation component 1 and a circulation component 2 are installed on the outside of the base 1, the circulation component 1 is connected to the heat dissipation chambers 1 and 3, and the circulation component 2 is connected to the heat dissipation chamber 2;

[0042] Circulation components 1 and 2 generate airflow, the temperature of the airflow generated by circulation component 2 is lower than the temperature of the airflow generated by circulation component 1, and the airflows generated by circulation components 1 and 2 flow in opposite directions. Both circulation components 1 and 2 form a signal connection with the temperature alarm 114, and the temperature in the base 1 is continuously monitored through the temperature alarm 114, and a temperature threshold is preset;

[0043] When the temperature in the base 1 does not exceed the temperature threshold, the circulation component 1 controls the airflow to circulate;

[0044] When the temperature in the base 1 exceeds the temperature threshold, the circulation components 1 and 2 simultaneously control the circulation of the airflow;

[0045] The present invention continuously monitors the temperature in the area by setting a temperature alarm in the heat dissipation chamber 2. When the temperature reaches or exceeds a preset threshold, the temperature alarm will send a signal. The signal sent by the temperature alarm will be directly associated with the circulation components 1 and 2, and the circulation components 1 and 2 will be directly controlled. When the circulation components 1 and 2 receive the signal, the corresponding cooling mechanism will be triggered.

[0046] The design in the present invention includes a base structure of heat dissipation chambers one, two, and three, and circulation components one and two connected thereto, thereby realizing the diversification of heat dissipation paths. This design not only improves the heat dissipation efficiency, but also makes the heat dissipation structure more flexible and can be adaptively adjusted according to different working conditions. By optimizing the heat dissipation structure, the present invention solves the heat dissipation limitation problem caused by the fixed structure in the background technology, so that heat can be discharged from the gain medium in a timely and effective manner.

[0047] Further, the circulation component 1 includes heat dissipation tube groups 15 symmetrically arranged on the left and right sides of the shell 11, and the two heat dissipation tube groups 15 are both supplied with gas through an external air compressor, and the gas flows from one heat dissipation tube group 15 to the other heat dissipation tube group 15, wherein the heat dissipation tube group 15 includes a connecting shaft 151, a branch pipe 152, and a conduit 153, and the connecting shaft 151 is respectively connected to the heat dissipation chambers 1 and 3 through the branch pipes 152 arranged on both sides, and the connecting shaft 151 is externally connected to the air compressor through the conduit 153;

[0048] The cooling gas enters the heat dissipation cavity 1 through the branch pipe 152 from the connecting shaft 151 of one of the heat dissipation tube groups 15. After the gas exchanges heat with the laser amplifier or other heat sources in the heat dissipation cavity 1, it enters another heat dissipation tube group 15 through the gas outlet 113 and the adjacent branch pipe 152. In the other heat dissipation tube group 15, the gas can be cooled again by the air compressor connected thereto, and then returned to the air compressor through the conduit 153 for recycling, or discharged to the external environment.

[0049] An air inlet 112 and an air outlet 113 are provided on both sides of the inner ends of the first and third heat dissipation chambers. The air inlet 112 and the air outlet 113 are respectively connected to the adjacent branch pipes 152. The air inlet 112 is connected to the inside of the base 1 through a strip-shaped gap provided on its surface, and the air outlet 113 is connected to the inside of the base 1 through a strip-shaped opening provided on its surface. When the airflow circulates, the airflow speed at the air inlet 112 is faster than the airflow speed at the air outlet 113.

[0050] The housing 11 is divided into heat dissipation chambers 1, 2 and 3 by a lens 12 arranged on the inner side thereof. A card slot 1 111 is arranged on the surface of the housing 11. A card slot 21 is arranged at the lower end of the cover plate 2. The lens 12 is embedded in the card slot 21 and the card slot 1 111 for fixing. A dust-proof assembly 13 is arranged in the heat dissipation chambers 1 and 3. A light-transmitting panel 14 is arranged in the heat dissipation chamber 2. The light-transmitting panel 14 is fixed in the heat dissipation chamber 2 by a support member 141 arranged at the lower end thereof. There is a gap between the lower end of the light-transmitting panel 14 and the surface of the heat dissipation chamber 2. The laser passes through the lens 12 and the light-transmitting panel 14 in sequence.

[0051] It should be explained that the dust isolation assembly 13 is used to prevent dust and other impurities from entering the heat dissipation system, thereby keeping the system clean and running efficiently. The dust isolation assembly can also reduce the resistance of gas flow and improve the heat dissipation efficiency.

[0052] The heat dissipation chamber 2 is connected to the outside through the oblique hole 115 arranged on the lower side thereof, and the oblique holes 115 are arranged symmetrically. The circulation component 2 includes a pressure-stabilizing low-temperature pipe 16 symmetrically arranged on the left and right sides of the shell 11. Both pressure-stabilizing low-temperature pipes 16 are supplied with air through an external air compressor. The pressure-stabilizing low-temperature pipe 16 is connected to each oblique hole 115 through a connecting auxiliary pipe 161 arranged on the side thereof, and the pressure-stabilizing low-temperature pipe 16 is provided with a pressure relief and dust discharge port 162 connected to the outside near each connecting auxiliary pipe 161.

[0053] The airflow temperature produced by the air compressor connected to the pressure-stabilizing low-temperature tube 16 is lower than the airflow temperature produced by the air compressor connected to the heat dissipation tube group 15;

[0054] It should be explained that the pressure relief dust exhaust port 162 is suitable for relieving pressure when the pressure-stabilizing low-temperature pipe 16 provides a flow path for the gas, and blows dust out of the pressure relief dust exhaust port 162 during the pressure relief transfer. Figure 5 As shown in , it is 90°, and the oblique hole 115 also penetrates outward in an inclined shape, so the light will not irradiate into the heat dissipation chamber 2 to affect the irradiation and transmission of the laser. In order to further avoid letting dust enter the heat dissipation chamber 2 while cooling by accelerating the gas flow rate, a dust isolation component 13 is provided in the present invention, and the dust isolation component 13 includes a filter plate 1 131 and a filter plate 2 132. The filter plate 1 131 is arranged horizontally, and the filter plate 2 132 is arranged vertically. The filter plate 1 131 is arranged symmetrically, and the filter plate 2 132 is provided with three, and gaps are provided between two adjacent filter plates 1 131 and two adjacent filter plates 2 132;

[0055] The angle between the filter plate 1 131 and the filter plate 2 132 is 90°, and a dust isolation assembly 13 is provided between two adjacent lenses 12 provided in the heat dissipation chambers 1 and 3, and the dust isolation assembly is used to intercept dust and ensure the flow of gas in the heat dissipation chambers 1 and 3 and the cooling effect;

[0056] Since a temperature alarm is provided in the heat dissipation chamber 2, the temperature of the area will be continuously monitored. When the temperature alarm detects that the temperature in the heat dissipation chamber 2 exceeds the preset temperature threshold, a signal will be immediately sent to the circulation components 1 and 2. After receiving the signal from the temperature alarm, the circulation components 1 and 2 will immediately start the cooling mechanism. If the temperature does not exceed the threshold but is close to the upper limit, the control system may pre-adjust the parameters of the heat dissipation system to prevent the temperature from further rising.

[0057] Different from the heat dissipation pipe group, the air flow temperature produced by the air compressor connected to the voltage-stabilizing low-temperature pipe 16 is relatively low, which is used to provide additional cooling effect for the heat dissipation chamber 2. When the control system starts the cooling mechanism, the voltage-stabilizing low-temperature pipe starts to work, and transmits the low-temperature air flow to the oblique hole 115 in the heat dissipation chamber 2 through the connecting auxiliary pipe 161. In addition, the oblique holes 115 are symmetrically arranged, which helps to evenly distribute the low-temperature air flow in the heat dissipation chamber 2. The connecting design of the connecting auxiliary pipe 161 and the oblique hole 115 ensures that the low-temperature air flow can smoothly enter the heat dissipation chamber 2. The cooling process is described in detail below:

[0058] After receiving the signal from the temperature alarm, the control system will start the air compressor connected to the voltage-stabilizing low-temperature tube 16. The air compressor starts to produce low-temperature airflow and transports the low-temperature airflow to the voltage-stabilizing low-temperature tube 16 through a conduit. The low-temperature airflow enters from the connecting sub-tube 161 arranged on the side of the voltage-stabilizing low-temperature tube 16. After the airflow passes through the connecting sub-tube 161, it enters the heat dissipation chamber 2 along the direction of the oblique hole 115. The inclined design of the oblique hole 115 helps to evenly distribute the airflow in the heat dissipation chamber 2. The low-temperature airflow exchanges heat with heat dissipation elements such as lenses, laser amplifiers, etc. in the heat dissipation chamber 2, absorbs heat from the heat dissipation elements, and as the heat exchange proceeds, the temperature in the heat dissipation chamber 2 gradually decreases.

[0059] Furthermore, in order to further improve the heat dissipation effect, the surfaces of the lenses 12 disposed near the ends of the light-transmitting panel 14 in the heat dissipation cavities 1 and 3 of the present invention are provided with communication openings 121, and the heat dissipation cavities 1 and 3 are respectively connected to the heat dissipation cavity 2 through the adjacent communication openings 121;

[0060] When the temperature in the heat dissipation chamber 2 exceeds the temperature threshold, the air compressor connected to the voltage-stabilizing low-temperature tube 16 controls the airflow to flow into the heat dissipation chamber 2, and flows to the heat dissipation chambers 1 and 3 respectively through the connecting ports 121 provided on the surfaces of the lenses 12 on both sides, and finally flows out through the adjacent air outlets 113;

[0061] When the temperature in the heat dissipation chamber 2 does not exceed the temperature threshold, the airflow flows into the heat dissipation chamber 2 through the heat dissipation chambers 1 and 3 connected to the heat dissipation tube group 15, and flows to the circulation component 2 through the oblique hole 115 and is discharged.

[0062] The following describes in detail the cooling management method when the temperature in the heat dissipation cavity 2 exceeds or does not exceed the temperature threshold:

[0063] When the temperature in the heat dissipation chamber 2 does not exceed the temperature threshold:

[0064] When the temperature in the heat dissipation chamber 2 is kept below the preset threshold, the control system will adjust the operating state of the heat dissipation system to reduce unnecessary energy consumption. At this time, the air compressor connected to the heat dissipation pipe group 15 starts to work to provide cooling airflow for the heat dissipation chamber 1 and the heat dissipation chamber 3.

[0065] The airflow first enters heat dissipation chamber 1 and heat dissipation chamber 3, exchanges heat with heat dissipation elements such as lens 12, and then flows into heat dissipation chamber 2. In heat dissipation chamber 2, the airflow flows to circulation component 2, that is, voltage-stabilizing low-temperature tube 16, through oblique holes 115.

[0066] In the circulation component 2, the airflow may be further cooled and then discharged through the pressure relief dust discharge port 162, or directly returned to the air compressor connected thereto for recycling. This process not only helps to maintain the temperature in the heat dissipation chamber 2 stable, but also effectively prevents dust and other pollutants from entering the heat dissipation system.

[0067] In summary, the heat dissipation system of the present invention achieves effective control of the temperature in heat dissipation chambers one, two, and three by flexibly adjusting the flow direction of the airflow and the heat dissipation mechanism, thereby ensuring the stability and efficient operation of optical components such as laser amplifiers.

[0068] When the temperature in the heat dissipation cavity 2 exceeds the temperature threshold:

[0069] When the temperature monitor in the heat dissipation chamber 2 detects that the temperature exceeds the preset threshold, the control system automatically starts the air compressor connected to the pressure-stabilizing low-temperature pipe 16. At this time, the air compressor starts to produce low-temperature airflow and transports this low-temperature airflow to the pressure-stabilizing low-temperature pipe 16 through a series of pipes.

[0070] As the low-temperature airflow continues to be input, the pressure in the heat dissipation cavity 2 gradually increases. This increased cold air pressure not only helps to dissipate the heat in the heat dissipation cavity 2, but also promotes the gas flow in the heat dissipation cavity.

[0071] In the heat dissipation chamber 2, the gas originally entering through the inlet 112 begins to flow toward the outlet 113 under the action of the cold air. At the same time, since the cold air produced by the voltage-stabilizing low-temperature tube 16 increases the pressure in the heat dissipation chamber 2, it also flows into the heat dissipation chamber 1 and the heat dissipation chamber 3 through the connecting port 121 provided on the surface of the lens 12.

[0072] After being pushed by the cold air from the heat dissipation chamber 2, the gas in the heat dissipation chamber 1 and the heat dissipation chamber 3 also begins to flow toward their respective outlets 113. In this way, the gas in the heat dissipation chambers 1, 2, and 3 forms an integral flow cycle.

[0073] Finally, after heat exchange in heat dissipation chambers 1, 2, and 3, the airflow mixed with the original gas and the cold air will flow out from the adjacent outlet 113, completing the entire heat dissipation cycle. In this process, the temperature in heat dissipation chamber 2 is effectively reduced, thereby ensuring the stable operation of optical components such as laser amplifiers.

[0074] Summary of gas flow characteristics:

[0075] Cold air push: The cold air produced by the pressure-stabilizing low-temperature tube 16 not only directly cools the heat dissipation cavity 2, but also pushes the gas flow in the heat dissipation cavity by increasing the pressure.

[0076] Communication port design: The communication port 121 provided on the surface of the lens 12 enables the gases in the first, second and third heat dissipation chambers to circulate with each other, thereby achieving a balanced distribution of heat.

[0077] Overall circulation: The gases in heat dissipation chambers 1, 2, and 3 form an overall flow cycle, which helps to effectively dissipate heat and ensure stable operation of the system.

[0078] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
