Technical Field
[0001] The present invention relates to the technical field of fish attracting lamps, and in particular to a phase change heat dissipation system of a fish attracting lamp. Background Art
[0002] Currently, in response to national requirements for green environmental protection and sustainable development of the fishery sector, the selection of new LED lamps for installation on fishing vessels as fish-attracting lights has become a trend. Fish-attracting lights are special lighting devices used to attract fish. However, existing fish-attracting lights generally use air-cooling, water-cooling, or natural heat dissipation mechanisms for heat dissipation. These heat dissipation structures emit relatively low amounts of heat per unit time. Therefore, to ensure stable operation, the power density of a single fish-attracting light is relatively low to accommodate the heat dissipation load of the heat dissipation structure. However, to meet the lighting requirements for attracting fish, the total power requirements of existing fish-attracting lights are generally very high. To increase the total power of fish-attracting lights, the method of adding lamps is usually adopted. However, this method increases the number and density of lamps, which not only increases the overall weight of the fishing vessel, but also increases the wind resistance of the fishing vessel due to the reduced spacing between the lamps, thereby affecting the safety of the fishing vessel's navigation and fishing. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a phase change heat dissipation system for a fish attracting lamp, which can improve the heat dissipation efficiency, thereby increasing the power density of the lamp, reducing the weight of the fish attracting lamp, and ensuring the safe operation of fishing boats.

The gaseous heat dissipation medium generated in the accommodating box can enter the cooling box through the air pipe device, and the liquid heat dissipation medium generated in the cooling box can enter the accommodating box through the liquid pipe device.
[0007] As an improvement of the above solution, the cooling box includes a gas accommodating area and a liquid accommodating area, the gas pipe device is connected to the gas accommodating area, and the liquid pipe device is connected to the liquid accommodating area.

The first exhaust valve is connected to the accommodating box, one end of the valve branch pipe is connected to the first exhaust valve, and the other end of the valve branch pipe is connected to the exhaust pipe.
[0011] As an improvement to the above solution, the communication component further includes a pressure sensor, and the pressure sensor is connected to the exhaust pipe.

BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 It is a schematic diagram of the phase change heat dissipation system of the fish attracting lamp of the present invention. DETAILED DESCRIPTION
[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.
[0020] See also Figure 1The embodiment of the present invention discloses a phase change heat dissipation system for a fish attracting lamp, comprising a fish attracting lamp assembly 1, a condensation assembly 2 connected to the fish attracting lamp assembly 1, and a connection assembly 3 connected between the fish attracting lamp assembly 1 and the condensation assembly 2. The fish attracting lamp assembly 1 comprises a containing box 11 and a lamp 12 provided in the containing box 11, the containing box 11 is used to accommodate and fix the lamp 12 and dissipate heat for the lamp 12, the containing box 11 is connected to the heat dissipation structure of the lamp 12, a liquid heat dissipation medium in contact with the lamp 12 is provided in the containing box 11, the heat generated by the lamp 12 can be transferred to the liquid heat dissipation medium, and the liquid heat dissipation medium undergoes a phase change after reaching a certain temperature, changing from liquid to gas to become a gaseous heat dissipation medium, the condensation assembly 2 comprises a cooling box 21. The cooling box 21 is connected to the external cooling system. The cooling box 21 can accommodate gaseous heat dissipation medium and liquid heat dissipation medium. The gaseous heat dissipation medium enters the cooling box 21 through the connecting component 3 and exchanges heat with the external cooling system. The temperature of the gaseous heat dissipation medium drops. After reaching a certain temperature, a phase change occurs, and it changes from gas to liquid, becoming a liquid heat dissipation medium. The liquid heat dissipation medium gathers in the cooling box 21 and returns to the containing box 11 through the connecting component 3, continuing to absorb heat from the lamp 12, thereby forming a cycle.
[0021] The connecting component 3 includes an air pipe device 31 and a liquid pipe device 32, wherein the air pipe device 31 and the liquid pipe device 32 are both connected between the accommodating box 11 and the cooling box 21. The gaseous heat dissipation medium generated in the accommodating box 11 can enter the cooling box 21 through the air pipe device 31, and the liquid heat dissipation medium generated in the cooling box 21 can enter the accommodating box 11 through the liquid pipe device 32, thereby forming a circulating and connected pipeline.
[0022] The beneficial effects of the embodiments of the present invention are as follows:
[0023] The phase change heat dissipation system of the fish collecting lamp in the embodiment of the present invention is provided with a fish collecting lamp assembly 1, a condensation assembly 2 and a connecting assembly 3 connected between the fish collecting lamp assembly 1 and the condensation assembly 2, wherein the fish collecting lamp assembly 1 includes a containing box 11 and a lamp 12 arranged in the containing box 11, and the containing box 11 is provided with a liquid heat dissipation medium in contact with the lamp 12, and the heat emitted by the lamp 12 can cause the liquid heat dissipation medium to undergo a phase change, and the heat dissipation medium is changed from liquid to gas. After absorbing the latent heat to form a gaseous heat dissipation medium, the gaseous heat dissipation medium enters the cooling box 21 of the condensation assembly 2 through the air pipe device 31, and the gaseous heat dissipation medium is cooled by the external cooling system, so that the gaseous heat dissipation medium releases the latent heat and re-condenses into a liquid heat dissipation medium, and then the liquid heat dissipation medium returns to the containing box 11 through the air pipe device 31 to continue to absorb heat from the lamp 12, thereby completing the cycle. In this process, the liquid heat dissipation medium can absorb a large amount of latent heat of phase change. Compared with traditional cooling methods that absorb sensible heat such as air cooling and water cooling, the cooling method that absorbs latent heat is more efficient and can greatly reduce the temperature of the lamp 12. Under this condition, the power of the lamp 12 is improved. When the total power requirement is certain, the installation of fish-attracting lamps can be reduced, thereby reducing the weight of the fish-attracting lamps and the wind resistance of the fishing boat, ensuring the safe driving of the fishing boat.
[0024] The cooling box 21 includes a gas accommodating area 211 and a liquid accommodating area 212. In an embodiment of the present invention, the gas accommodating area 211 is located above the liquid accommodating area 212 to facilitate the gaseous heat dissipation medium to enter the cooling box 21 and facilitate the liquid heat dissipation medium to flow smoothly back into the accommodating box 11 by gravity. The gas pipe device 31 is in communication with the gas accommodating area 211, and the liquid pipe device 32 is in communication with the liquid accommodating area 212. The gaseous heat dissipation medium enters the gas accommodating area 211 through the gas pipe device 31, condenses within the gas accommodating area 211, and is collected in the liquid accommodating area 212 by gravity, and then flows back to the accommodating box 11 through the liquid pipe device 32.
[0025] In order to make the liquid heat dissipation medium easily undergo a phase change to become a gaseous heat dissipation medium, the connecting component 3 also includes a vacuum pump component 33, which is connected to the gas accommodating area 211. The vacuum pump component 33 can be connected to the air pipe device 31 and the accommodating box 11 through the gas accommodating area 211. By vacuuming, the pressure in the air pipe device 31 and the accommodating box 11 can be reduced. After the pressure is reduced, the evaporation temperature of the heat dissipation medium also decreases with the reduction in pressure. In this way, the liquid heat dissipation medium is more likely to undergo a phase change to become a gaseous heat dissipation medium, thereby absorbing more heat from the lamp 12 at room temperature, and the heat dissipation efficiency is higher.
[0026] Specifically, the air pipe device 31 includes an exhaust pipe 311 and a gas conveying member 312. The gas conveying member 312 is provided on the exhaust pipe 311 and is connected to the exhaust pipe 311. The gas conveying member 312 is preferably a fan, which can accelerate the flow of the gaseous heat dissipation medium in the exhaust pipe 311. One end of the exhaust pipe 311 is connected to the containing box 11, and the other end is connected to the gas containing area 211. The air pressure of the gas containing area 211 is equal to that of the containing box 11.
[0027] In addition, the connecting assembly 3 further includes a valve device 34 for controlling the flow direction of the gaseous heat dissipation medium and the liquid heat dissipation medium. The valve device 34 includes a first exhaust valve 341 and a valve branch pipe 342. The first exhaust valve 341 is in communication with the accommodating box 11. One end of the valve branch pipe 342 is in communication with the first exhaust valve 341, and the other end of the valve branch pipe 342 is in communication with the exhaust pipe 311. The first exhaust valve 341 is disposed between the accommodating box 11 and the exhaust pipe 311, allowing only gas to pass through, not liquid. Within the accommodating box 11, heat dissipation medium that has not yet formed a gaseous state cannot pass through the first exhaust valve 341, thereby ensuring that the gaseous heat dissipation medium in the exhaust pipe 311 can circulate normally and that the liquid heat dissipation medium can specifically absorb heat emitted by the lamp 12.
[0028] The communication component 3 further includes a pressure sensor 35, which is connected to the exhaust pipe 311. The pressure sensor 35 can detect the air pressure in the exhaust pipe 311 and the container 11 to control the evaporation temperature of the heat dissipation medium and thus regulate the heat absorption of the heat dissipation medium.
[0029] The valve assembly 34 also includes a drain valve 343 and a drain branch pipe 344. The drain valve 343 is in communication with the storage tank 11. The liquid pipe assembly 32 includes a return pipe 321. One end of the drain branch pipe 344 is in communication with the drain valve 343, and the other end of the drain branch pipe 344 is in communication with the return pipe 321. One end of the return pipe 321 is in communication with the liquid storage area 212. The drain valve 343 is located between the return pipe 321 and the storage tank 11, allowing liquid to pass but not gas to pass, ensuring that the condensed liquid heat dissipation medium returns to the storage tank 11 through the return pipe 321. To achieve an unpowered self-circulating process, a siphon structure is provided in the drain branch pipe 344. Liquid heat dissipation medium that returns to the return pipe 321 by gravity can then be returned to the storage tank 11 through the siphon structure, thus completing liquid circulation without the need for additional power. This method can simplify the structure of the heat dissipation system, reduce costs and lighten the weight of the heat dissipation system, thereby further ensuring the safe and stable navigation of fishing boats.
[0030] In addition, the valve device 34 also includes a second exhaust valve 345, one end of the second exhaust valve 345 is connected to the exhaust pipe 311, and the other end of the second exhaust valve 345 is connected to the return liquid pipe 321. The second exhaust valve 345 can discharge the gas in the return liquid pipe 321 to prevent the gaseous heat dissipation medium from occupying the space of the return liquid pipe 321.
[0031] To replenish the heat dissipation medium within the system, the phase-change heat dissipation system for attracting fish lamps further includes a liquid inlet assembly 4, which includes a liquid inlet valve 41 and a liquid inlet pipe 42. The liquid inlet valve 41 is connected to an external heat dissipation medium source, and one end of the liquid inlet pipe 42 is connected to the liquid inlet valve 41, while the other end of the liquid inlet pipe 42 is connected to the cooling tank 21. The discharged gaseous heat dissipation medium can be replenished through the liquid inlet valve 41 and the liquid inlet pipe 42 to maintain stable cyclic operation of the system.
[0032] In this embodiment of the present invention, there are at least two air pipe devices 31 , which are connected in parallel and communicate with the gas storage area 211 . Multiple air pipe devices 31 can increase the flow rate of the gaseous heat dissipation medium, further improving heat dissipation efficiency. The pressure sensor 35 can be disposed between adjacent air pipe devices 31 .
[0033] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
