Abstract

The utility model relates to a mechanical radiating device, in particular to a high-power LED street lamp with a liquid circulating radiating function. The high-power LED street lamp comprises a first connecting pipe, a second connecting pipe, a lamp panel, a silent water pump, a radiator and a cooling plate. A cooling pipe is arranged inside the radiator, and another cooling pipe is arranged inside the cooling plate. The high-power LED street lamp has the advantages that water is used as a cooling medium, the specific heat capacity of the water is about triple the specific heat capacity of air, and accordingly a large quantity of heat can be absorbed in a water cooling mode while identical temperatures are dropped in the water cooling mode as compared with the air; the cooling plate is in close contact with an LED lamp, so that the heat can be absorbed by the water in the corresponding cooling pipe to a great extent, the water with the high heat content is pushed to radiating fins by the silent water pump to be dissipated, the high-power LED street lamp can keep in a stable temperature range as cycle repeats, and the service life of the lamp can be effectively prolonged.

Description

A kind of liquid circulation cooling high-power LED street lamp

Technical field

The utility model relates to a kind of mechanical heat abstractor, is specifically related to a kind of liquid circulation cooling high-power LED street lamp.

Background technology

Great power LED street lamp is that illumination in night is provided convenience, high-power LED street lamp also gives out a large amount of heat when light source is provided, the heat giving out had a significant impact the life-span of high-power LED street lamp, ensured that heat spreads out of fast, was the effective way that extends the life-span of high-power LED street lamp.

Chinese patent discloses " a kind of cool-down method of great power LED street lamp and adopt the LED street lamp of its cooling " (notification number is: CN 103062736A), its shortcoming is as follows: its type of cooling relies on chimney principle, and the degree of the intensity of stack effect and the height of chimney, chimney inside and outside temperature difference and the circulation of chimney inner air and outer air is relevant; Generally the circulation of street lamp ambient air is slower, although street lamp is hollow design but there is a big difference with the vertical chimney of reality, because specific heats of gases appearance is relatively little, the degree that while taking away heat, temperature reduces not is very large again, therefore cooling effect is also not obvious in actual applications.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of simple in structure, heat radiation liquid circulation cooling high-power LED street lamp quickly.

For solving above technical problem, the utility model adopts following technical scheme: the utility model comprises that radiator and inside that the first adapter, the second adapter, lamp plate, silencing water pump, inside are provided with cooling tube are provided with cooling tube coldplate; Described radiator tail end is provided with first interface and the second interface, and described coldplate tail end is provided with the 3rd interface and the 4th interface; Described coldplate is arranged on lamp plate, described first takes over two ends is communicated with the first interface of radiator tail end, the 3rd interface of coldplate tail end respectively, and described silencing water pump is communicated with the second interface of radiator tail end, the 4th interface of coldplate tail end respectively through the second adapter.

Described cooling tube is all wheel loop-wire and arranges in coldplate and radiator.

The model of described silencing water pump is the woods Multifunctional submersible pump BL-007 of Bldxbly Derby.

Good effect of the present utility model is as follows: the utility model utilizes water for cooling medium, compares air specific heat of water and holds and be about three times of air, and in the time reducing identical temperature, the heat that adopts the mode of water-cooled to absorb is more; Due to coldplate and LED lamp close contact, this just makes the water that heat can greatly be cooled in pipe absorb, by silencing water pump, water higher heat content being pushed to fin place dispels the heat, so circulation can make high-power LED street lamp maintain in a stable temperature range, has effectively extended the life-span of lamp; The utility model is simple in structure, and area of dissipation is larger, and radiating effect is remarkable, when installation without particular/special requirement, convenient operation.

Brief description of the drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model heat spreader structures schematic diagram;

Fig. 3 is the utility model plate structure of cooling schematic diagram;

In the drawings: 1 radiator, 1-1 first interface, 1-2 the second interface, 2-1 first take over, 2-2 second takes over, 3 silencing water pumps, 4 lamp plates, 5 coldplates, 5-1 the 3rd interface, 5-2 the 4th interface, 6 cooling tubes.

Detailed description of the invention

As shown in Figure 1, 2, 3, the utility model comprises that the first adapter 2-1, second takes over radiator 1 and the inside that 2-2, lamp plate 4, silencing water pump 3, inside be provided with cooling tube 6 and is provided with cooling tube 6 coldplates 5; Described radiator 1 tail end is provided with first interface 1-1 and the second interface 1-2, and described coldplate 5 tail ends are provided with the 3rd interface 5-1 and the 4th interface 5-2; Described coldplate 5 is arranged on lamp plate 4, described first takes over 2-1 two ends is communicated with the first interface 1-1 of radiator 1 tail end, the 3rd interface 5-1 of coldplate 5 tail ends respectively, and described silencing water pump 3 is communicated with the second interface 1-2 of radiator 1 tail end, the 4th interface 5-2 of coldplate 5 tail ends respectively through the second adapter 2-2.Described cooling tube 6 is arranged at the interior wheel loop-wire that is all of coldplate 5 and radiator 1.The model of described silencing water pump 3 is the woods Multifunctional submersible pump BL-007 of Bldxbly Derby.

The utility model lamp plate 4 adopts aluminum base plate to make.

While using the utility model, when the lamp plate 4 of high-power LED street lamp is luminous, produce amount of heat, because coldplate 5 is closely connected with lamp plate 4, the cooling tube 6 that the heat overwhelming majority that lamp plate 4 produces can be cooled in plate 5 absorbs, in cooling tube 6, contain water, water is taken over 2-2 through the first adapter 2-1 and second and is circulated in radiator 1 and coldplate 5 under the drive of silencing water pump 3; Heat in radiator 1 is taken away through circulation of air, causes water temperature in radiator 1 to decline, and then gets back to again in coldplate 5 heat that the lamp plate 4 of continuation absorption high-power LED street lamp distributes.

The utility model cooling tube 6, coldplate 5, radiator 1 sealing strictly, can not produce leakage.

The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the utility model principle and spirit, it having been done, within all should being contemplated as falling with claim protection domain of the present utility model.
