Abstract

The utility model discloses a cooling device for an LED (Light-Emitting Diode) street lamp. The cooling device comprises a water cooling tank fixed on an LED light source, wherein a water pump is connected with one end of the water cooling tank through a water pipe; a heat radiator is connected with the other end of the water cooling tank through a water pipe; the heat radiator is connected with the water pump through the water pipe; a cold-heat shrinking buffer device is arranged on any one section of water pipe and comprises an open water storage tank; a shrink film is sealed on the opening of the water storage tank; and the water pipe is respectively connected with two ends of the water storage tank. The cold-heat shrinking buffer device is specially arranged in the cooling device of the LED street lamp, which is disclosed by the utility model; one layer of shrink film is sealed on the water storage tank, so that when the temperature in summer is high, cooling water upwards jacks the shrink film due to the expansion with heat and the shrink film bulges; the excessive volume of the cooling water subjected to expansion with heat can be released without causing burst of the water pipe; and when the temperature in winter is low, the volume of the cooling water is shrank, the shrink film is shrank and the cooling water of the whole cooling device is full.

Description

A kind of LED street lamp cooling device
Technical field
The utility model relates to the LED street lamp, particularly a kind of cooling device of LED street lamp.
Background technology
At present, the LED street lamp is owing to the advantage of its energy-conserving and environment-protective is widely used.But LED uses maximum problem and is temperature, and the temperature of led light source node directly affects the life-span and the luminous efficiency of street lamp, thus take variety of way that led light source is dispelled the heat now, so that its temperature can reduce.The radiating mode of LED street lamp mainly contains Natural Heat Convection, installs fan heat radiation, fin heat radiation etc. additional at present, and these several kinds of radiating mode effects are not fine.Have now and adopt water-cooling pattern to dispel the heat, promptly through the water cooler bin is set on led chip, and through water circle device with the heat radiation of flowing of the water in the water cooler bin.Though this mode is effective; But a bigger defective is arranged; Be exactly the problem of expanding with heat and contract with cold of water,, when injecting cooling water inside, generally fill with because whole water cooling plant seals; Uprise or water temperature raises time time when environment temperature like this, effect will make the water pipe explosion because the heat of water rises; If not filling with, water influences cooling effect.Since street lamp after installing whole led light source and cooling device all be sealed in and carry out waterproof within the lampshade, also can not carry out the increase and decrease of cooling water, so how well to address this problem just very important.
The utility model content
The purpose of the utility model provides a kind of LED street lamp cooling device of good cooling results, can effectively solve the failure problems that cooling water expanding with heat and contract with cold in cooling device causes.
The technical scheme of the utility model: a kind of LED street lamp cooling device, comprise the water cooler bin that is fixed on the led light source, water cooler bin one end connects water pump through water pipe; The other end connects radiator through water pipe; Radiator connects water pump through water pipe again, and a cold and hot contraction buffer unit is set on any one section water pipe, and cold and hot contraction buffer unit comprises uncovered storage tank; Be sealed with shrink film on storage tank is uncovered, the two ends of storage tank join with water pipe respectively.
Described shrink film is an elastic membrane, such as the film of material such as rubber.
Also be fixed with upper end cover above the described shrink film; Play the fixing of shrink film and the further effect of sealing.
Described radiator is provided with radiator fan; Further strengthen radiating effect.
A cold and hot contraction buffer unit is set in the LED street lamp cooling device of the utility model specially, and the storage tank of its bottom is used for storing and mobile cooling water, seals through shrink film above it; Storage tank both sides and water pipe join, and cooling water can circulate in whole cooling device through cold and hot contraction buffer unit like this, simultaneously owing to sealed one deck shrink film above the storage tank; When summer temperature was high, the reason cooling water that rises owing to heat can up push up shrink film, and shrink film can stick out; Additional volume energy accesses release after making cooling water heat rise like this; Can not cause the explosion of water pipe, when winter temperature is low, the cooling water volume-diminished; Shrink film shrinks down, and the cooling water of whole cooling device also is full.So just solved the failure problems that the shrinkage of cooling water heat expansion causes in the cooling device.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the cold and hot contraction buffer unit of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
Embodiment 1
As shown in Figure 1; A kind of LED street lamp cooling device comprises the water cooler bin 2 that is fixed on the led light source 1, and water cooler bin 2 one ends connect water pump 6 through water pipe; The other end connects radiator 3 through water pipe 8; Radiator 3 connects water pump 6 through water pipe 7 again, and cold and hot contraction buffer unit 5 is arranged on any one section water pipe in these water pipes, is that cold and hot contraction buffer unit 5 is set on the water pipe between cooling water tank 2 and the water pump 6 in the present embodiment; Thereby this section water pipe is divided into the water pipe 92 that connects water pump 6 and cold and hot contraction buffer unit 5, and the water pipe 91 that connects water cooler bin 2 and cold and hot contraction buffer unit 5.
As shown in Figure 2; Cold and hot contraction buffer unit 5 comprises uncovered storage tank 51; Be sealed with shrink film 52 on storage tank 51 uncovered; The elastic membrane that shrink film 52 can adopt the rubber elastomeric material to make, the two ends of storage tank 51 join with water pipe 91 and water pipe 92 respectively through pipe joint 511, pipe joint 512.Water cooler bin 2, water pump 6, storage tank 51, radiator 3 and connect the water cycle system that water pipe between them has constituted a sealing like this.Can also be fixed with upper end cover 53 above the shrink film 52, the centre of upper end cover 53 is provided with opening 531, and shrink film 52 can raise up through opening 531 like this.All have through hole on four angles of shrink film 52 and upper end cover 53, the corresponding screwed hole that has is fixed on upper end cover 53 and shrink film 52 on the storage tank 51 through screw like this on four angles of storage tank 51.Radiator 3 is provided with radiator fan 4.
Before using cooling device, the cooling water that adds anti-icing fluid is filled with whole device, the water yield of injection flushes with storage tank with the buffer film on the storage tank and is as the criterion; Water is if inject day cold the time like this, and hydro-thermal rises shrink film is heaved time day heat, if injection when water is day heat; Water-cooled contracts time day cold, and shrink film can shrink down, plays the effect of buffering; Cooling water all is full in cooling device like this, and it is quick-fried also can water pipe not to be risen.Circulate in the cooling device that acts on whole sealing of cooling water through water pump 6, dispel the heat fully, can play led light source is effectively cooled off through radiator 3.
