Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation, and in particular to a lamp with a water-cooling heat dissipation structure. Background Art

[0002] Some improved LED light sources with heat sinks have also been developed on the market. For example, according to the patent document of Chinese patent application number "201610083454.9", the light-emitting semiconductor LED device is water-cooled, etc. However, there are still many problems. For example, when water is injected into the hollow shell, bubbles are easily generated, which affects the heat dissipation effect. Conventional water cooling is only non-flowing water to cool the heat-generating LED device, but this effect is not good. Therefore, flowing water is used to improve the heat dissipation, but there are also corresponding problems:

[0003] Conventional water cooling does not regulate the water flow rate according to the amount of heat dissipation. It only uses conventional means to directly flow water to dissipate heat, that is, using a closed circulating water flow to cool the heat-generating LED devices. This is not conducive to heat dissipation. However, when the heat generated by the light-emitting semiconductor LED device increases, conventional water circulation cooling is difficult to achieve a good heat dissipation effect. For example, some bent LED lamps are prone to heat accumulation at the bent parts, and this part of the heat is difficult to dissipate. Therefore, if it is not removed in time, it will affect the service life of the LED lamp.

[0004] For this purpose, we designed a lamp with a water-cooling structure. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that some bent LED lamps easily accumulate heat at the bent parts, and this heat is difficult to dissipate. Therefore, if it is not removed in time, it will affect the service life of the LED lamp. A lamp with a water-cooling heat dissipation structure is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] Preferably, the connecting water pipe connects the two ends of the lamp tube clip frame, the micro pump is used to drive the flow of water in the connecting water pipe, the trigger adjustment device is connected to the micro pump, the two ends of the connecting water pipe are connected to the first cavity, the first cavity is connected to the water body of the connecting water pipe, and the connecting water pipe is also provided with a water replenishing tank for replenishing the water body, and a one-way valve is provided in the water replenishing tank.

[0009] Preferably, a lifting trigger rod inserted into the micro pump is slidably disposed on the second cavity, and the lifting trigger rod is retracted and reset by a compression spring.

[0010] Preferably, a water vapor evaporation portion is provided between the bending regions of the lamp tube clip frame, and a metal heat conducting rod for heat conduction passes through the lamp tube clip frame, and the water vapor evaporation portion is connected to the metal heat conducting rod.

[0011] Preferably, the water vapor evaporation portion comprises a water absorption rope for conducting water out of the second cavity.

[0012] Preferably, the water vapor evaporation part also includes a water infiltration bracket arranged in the bending area of ​​the lamp tube clip frame, and the water infiltration bracket is connected to the metal thermally conductive rod, and a hanging bracket is also provided on the water infiltration bracket, and the water absorption rope is located at the metal thermally conductive rod, the water infiltration bracket and the hanging bracket, and hangs at the bottom of the hanging bracket, and the water absorption rope is fixed in the metal thermally conductive rod through a rubber plug.

[0013] Preferably, a telescopic rod passes through the insulating arc plate, and a water retaining ring is provided at the end of the telescopic rod, which is sleeved on the metal thermally conductive rod and slides along the axis. A water conducting hole is opened on the metal thermally conductive rod, and a limiting ring is also fixed on the metal thermally conductive rod for limiting the water retaining ring.

[0014] Preferably, a plurality of elastic buckles for limiting the position of the bent LED lamp tubes are provided at the bottom of the lamp tube buckle frame.

[0015] The beneficial effects of the present invention are:

[0016] 1. In the present invention, the lamp tube clip frame is in direct contact with the heated LED bent lamp tube, so that the heat of the heated LED bent lamp tube can be directly transferred to the first cavity containing water in the lamp tube clip frame, thereby completing the initial cooling of the heated LED bent lamp tube, and then the water that has absorbed the heat will be taken away by the water circulation.

[0017] 2. The water in the water-absorbing rope of the present invention is located at the bending part of the LED curved lamp tube. This part emits more heat and has a poor heat dissipation effect. Therefore, the water is introduced into this area. The heat emitted by the LED curved lamp tube will heat this part of the water and slowly vaporize it.

DETAILED DESCRIPTION

[0026] Reference Figure 1-Figure 7 The lamp with a water-cooling and heat dissipation structure includes an outer frame 1 of the lamp and a micro pump 5 installed on the top of the outer frame 1 of the lamp. The micro pump 5 is used to drive the flow of water in the connecting water pipe 4. The micro pump 5 is used to circulate the water body, so as to transfer the heat emitted by the LED curved lamp tube 3 to the corresponding water body for flow heat dissipation, and timely flow the cold water body to the heating part to complete the flow replacement of the hot water body.

[0027] A lamp tube clip frame 2 is installed on the outer frame 1 of the lamp, and an LED bent lamp tube 3 is installed in the lamp tube clip frame 2, wherein a plurality of elastic clips 12 for limiting the LED bent lamp tube 3 are provided at the bottom of the lamp tube clip frame 2, so that the LED bent lamp tube 3 can be easily clipped into the lamp tube clip frame 2 through the elastic clips 12, thereby avoiding the LED bent lamp tube 3 from falling off, and at the same time ensuring that the groove of the lamp tube clip frame 2 can completely cover the upper half of the LED bent lamp tube 3, so that the heat emitted from the LED bent lamp tube 3 can be transferred to the lamp tube clip frame 2, that is, the water flowing in the lamp tube clip frame 2 is used to cool down the heat-absorbing lamp tube clip frame 2.

[0028] A connecting water pipe 4 for water circulation is installed on the outer frame 1 of the lamp. The connecting water pipe 4 connects the two ends of the lamp tube clip frame 2. A chamber is provided in the lamp tube clip frame 2, and an isolation arc plate 11 is provided in the chamber. The isolation arc plate 11 is used to divide the chamber into a first chamber 13 and a second chamber 14. This can ensure that the water in the first chamber 13 and the ethanol in the second chamber 14 do not flow between each other, and only serve as heat conduction.

[0029] Primary heat dissipation: both ends of the connecting water pipe 4 are connected to the first cavity 13 , and the first cavity 13 is connected to the water body of the connecting water pipe 4 , wherein the first cavity 13 and the connecting water pipe 4 form a complete water flow cycle.

[0030] It should be noted that the lamp tube clip frame 2 is in direct contact with the heated LED bent lamp tube 3, so that the heat of the heated LED bent lamp tube 3 can be directly transferred to the first cavity 13 containing water in the lamp tube clip frame 2, thereby completing the initial cooling of the heated LED bent lamp tube 3, and then this part of the water that has absorbed the heat will be taken away by the action of the water circulation. The second cavity 14 is filled with ethanol, and the water in the first cavity 13 heats up, which will transfer this part of the heat to the ethanol in the second cavity 14, completing the feedback of the heat of the water in the first cavity 13. The higher the water temperature in the first cavity 13, the more ethanol will be vaporized, and the greater the pressure in the second cavity 14.

[0031] A lifting trigger rod 7 inserted into the micro water pump 5 is slidably arranged on the second chamber 14, and the lifting trigger rod 7 is reset and retracted by the compression spring 16. When the pressure is greater, the lifting trigger rod 7 in the second chamber 14 will be lifted higher, and the size of the lifting trigger rod 7 inserted into the trigger adjustment device will be larger. The trigger adjustment device will be adjusted according to the inserted size and fed back to the micro water pump 5, thereby changing the first chamber 13 and the connecting water pipe 4 to form a complete water flow circulation flow rate, that is, the higher the temperature, the greater the water flow rate, and the faster the heat is taken away. A plurality of heat sinks are inserted on the connecting water pipe 4 to dissipate the heat of the hot water in the water pipe 4, to ensure that the water re-entering the first chamber 13 is in a cooled state.

[0032] Among them, a trigger adjustment device for triggering and changing the power of the micro-pump 5 is provided in the second chamber 14. The trigger adjustment device is connected to the micro-pump 5. The trigger adjustment device is a combination of a sliding rheostat and a current feedback unit. The lifting trigger rod 7 is used to adjust the slider position of the sliding rheostat, thereby adjusting the current size. Then the current feedback unit feeds back the current size to the micro-pump 5 to complete the power adjustment of the micro-pump 5. The trigger adjustment device is a prior art and will not be elaborated on here.

[0033] It should be noted that the heating of the LED curved lamp tube 3 is usually continuous, and conventional water cooling is not enough to complete the heat dissipation of the LED curved lamp tube 3. Therefore, it is necessary to use the evaporation heat absorption of water to complete the secondary heat dissipation of the heated LED curved lamp tube 3.

[0034] Secondary heat dissipation: When the water temperature in the first chamber 13 is not high, only the first chamber 13 and the connecting water pipe 4 form a complete water circulation flow to complete the heat dissipation of the heated LED curved lamp tube 3. When the temperature is too high, only relying on water circulation heat dissipation cannot meet the requirements, so water vapor evaporation will be used to absorb heat and cool down.

[0035] The LED curved lamp tube 3 itself can work at a low temperature, and some high-power LED curved lamp tubes 3 can often reach above 100 degrees Celsius when working. For example, the LED landscape lamp has a rated power of 22W and is used outdoors. The LED curved lamp tube 3 of the landscape lamp will emit a high temperature of more than 100 degrees Celsius during use. This high temperature above 100 degrees Celsius has an impact on the life of the LED curved lamp tube 3. Therefore, it is necessary to perform secondary heat dissipation and cooling on this part of the high-power LED curved lamp tube 3.

[0036] Reference Figure 4 State, a water vapor evaporation portion is arranged between the bending areas of the lamp tube clip frame 2, and a metal heat conducting rod 15 for heat conduction is penetrated through the lamp tube clip frame 2, the water vapor evaporation portion is connected to the metal heat conducting rod 15, the water vapor evaporation portion is arranged to guide out a part of the water in the first cavity 13, so that this part of the water is located at the bending part of the LED curved lamp tube 3, this part distributes more heat and has a poor heat dissipation effect, therefore, the water is introduced into this part of the area, the heat emitted by the LED curved lamp tube 3 will heat this part of the water and slowly vaporize, and the vaporization of water vapor absorbs heat, which can also reduce the temperature of the bending part of the LED curved lamp tube 3, thereby achieving a cooling effect on the LED curved lamp tube 3.

[0037] A telescopic rod 19 passes through the isolation arc plate 11, and a water retaining ring 18 is provided at the end of the telescopic rod 19, which is sleeved on the metal heat conducting rod 15 and slides along the axis. A water conducting hole 20 is opened on the metal heat conducting rod 15, and a limiting ring 17 for limiting the water retaining ring 18 is fixed on the metal heat conducting rod 15. The water absorption rope 10 is fixed in the metal heat conducting rod 15 through a rubber plug 21. When the temperature rises, the ethanol evaporation pressure in the second cavity 14 increases, which will push the telescopic rod 19 to slide and drive the water retaining ring 18 to slide, so that the originally blocked water conducting hole 20 leaks out. One end of the water absorption rope 10 is located in the water conducting hole 20, so that the water in the first cavity 13 will enter the water absorption rope 10 of the water conducting hole 20, allowing the water absorption rope 10 to complete the water absorption function.

[0038] The water vapor evaporation part includes a water absorption rope 10 for draining water out of the first cavity 13. The function of the water absorption rope 10 is to be used for the water in the first cavity 13 to wet the water absorption rope 10. The water vapor evaporation part also includes a water infiltration bracket 8 arranged in the bending area of ​​the lamp tube clip frame 2, and the water infiltration bracket 8 is connected to the metal thermal conductive rod 15. A hanging bracket 9 is also provided on the water infiltration bracket 8. The water absorption rope 10 is located on the metal thermal conductive rod 15, the water infiltration bracket 8 and the hanging bracket 9, and hangs down at the bottom of the hanging bracket 9. In this way, the wetted water absorption rope 10 will be in a vertical state, so the water vapor evaporation and heat absorption of the wet water absorption rope 10 can be completed, thereby achieving a cooling effect on the LED curved lamp tube 3.

[0039] A water replenishment tank 6 for replenishing the water body is also provided on the connecting water pipe 4, and a one-way valve is provided in the water replenishment tank 6. The one-way valve is used to allow the water in the water replenishment tank 6 to flow into the connecting water pipe 4, while the water in the connecting water pipe 4 cannot flow into the water replenishment tank 6, that is, after the water in the first chamber 13 is discharged, a negative pressure will be formed in the first chamber 13 and the connecting water pipe 4, so the water in the water replenishment tank 6 will flow from the one-way valve into the connecting water pipe 4 to complete the water replenishment effect.

[0040] The working principle of the present invention is as follows:

[0041] The micro pump 5 is used to circulate the water body, so as to transfer the heat emitted by the LED curved lamp tube 3 to the corresponding water body for flow heat dissipation, and timely flow the cold water body to the heating part to complete the flow replacement of the hot water body. This method is a one-time heat dissipation. The first cavity 13 is connected with the water body connected to the water pipe 4, wherein the first cavity 13 and the connected water pipe 4 form a complete water flow cycle, and the lamp tube clip frame 2 is in direct contact with the heated LED curved lamp tube 3, so that the heat of the heated LED curved lamp tube 3 can be directly transferred to the first cavity 13 containing water in the lamp tube clip frame 2, so that the heated LED curved lamp tube 3 can be initially cooled, and then this part The water body that has absorbed the heat will be taken away under the action of water circulation. The second chamber 14 is filled with ethanol. The water body in the first chamber 13 heats up, and this part of the heat will be transferred to the ethanol in the second chamber 14, completing the feedback of the heat of the water body in the first chamber 13. At the same time, the triggering regulating device will be adjusted according to the inserted size and fed back to the micro pump 5, thereby changing the flow rate of a complete water flow circulation formed by the first chamber 13 and the connecting water pipe 4, that is, the higher the temperature, the greater the water flow rate, and the faster the speed of taking away the heat. The connecting water pipe 4 is provided with a plurality of heat sinks for dissipating the heat of the hot water in the water pipe 4, ensuring that the water body re-entering the first chamber 13 is already in a cooled state;

[0042] Then secondary heat dissipation will be generated. A water vapor evaporation portion is arranged between the bending areas of the lamp tube clip frame 2, and a metal heat conducting rod 15 for heat conduction is penetrated through the lamp tube clip frame 2. The water vapor evaporation portion is connected to the metal heat conducting rod 15. The water vapor evaporation portion is arranged to guide out a part of the water in the first cavity 13, so that this part of the water is located at the bending part of the LED curved lamp tube 3. This part distributes more heat and has a poor heat dissipation effect. Therefore, the water is introduced into this part of the area. The heat emitted by the LED curved lamp tube 3 will heat this part of the water and slowly vaporize it. The vaporization of water vapor absorbs heat, which can also reduce the temperature of the bending part of the LED curved lamp tube 3, thereby achieving a cooling effect on the LED curved lamp tube 3.

[0043] Finally, the one-way valve is used to allow the water in the water replenishment tank 6 to flow into the connecting water pipe 4, while the water in the connecting water pipe 4 cannot flow into the water replenishment tank 6, that is, after the water in the first chamber 13 is discharged, a negative pressure will be formed in the first chamber 13 and the connecting water pipe 4, so the water in the water replenishment tank 6 will flow from the one-way valve into the connecting water pipe 4 to complete the water replenishment function.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
