Abstract
The utility model discloses an internal recycle heat dissipation system for a light-emitting diode (LED) street lamp, which comprises a lamp casing and an LED lamp. A heat dissipation body is fixedly arranged in the lamp casing. The LED lamp is fixed at the position just below the heat dissipation body which is in a hollow shape and formed by a bent evaporating board. A plurality of evaporating pipes communicated with each other are distributed on the whole inner lateral face of the evaporating board. Cooling media are arranged in the evaporating pipes. A circulating circuit is formed among the plurality of evaporating pipes. The heat dissipation body is provided with a circulating evaporating pipe circuit, and the heat absorbed by the cooling media is dissipated through the evaporating pipe circuit, so the LED dissipates the heat more quickly. Simultaneously, a heat dissipation device can be arranged on the lateral face of the heat dissipation body, thereby improving heat dissipation effect. Furthermore, the structure is simple, the cost is low, and the whole appearance is not affected.
Description
Technical field
The utility model relates to a kind of LED cooling system, particularly a kind of LED street lamp cooling system with internal circulation.
Background technology
Because the continuous development of LED technology, so LED is applied to street lighting in a large number.The temperature of the performance of LED and life-span and the working environment relation of being inversely proportional to.The temperature resistant capability of LED own is poor, the heat that produces in the time of the LED luminous tube must being worked effectively is dispersed in the air, could guarantee that led chip is operated under the safe temperature environment, the LED lamp could be real embody long-life advantage, the LED shell is subjected to the restriction of encapsulating material, the LED skin temperature is advisable to be no more than 70 ℃, at this moment the material of LED just can quick aging, light decay is slow, can work steadily in the long term, general LED street lamp is in order to solve heat dissipation problem, and the radiator structure design is complicated, consumptive material is many, the structure heaviness, and its radiating effect is also desirable not to the utmost.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of LED street lamp cooling system with internal circulation, and the cooling system good heat dissipation effect of this LED street lamp is simple in structure, and does not influence the street lamp outward appearance.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of LED street lamp cooling system with internal circulation, comprise lamp housing and LED lamp, be fixed with a radiator in the described lamp housing, the LED lamp is fixed under the radiator, radiator is hollow form, radiator is made of the evaporation plate of bending, and the medial surface of evaporation plate is covered with some evaporation tubes that are connected, be provided with cooling medium in the evaporation tube, form closed circuit between described some evaporation tubes, LED lamp heat is delivered to the cooling medium of radiator below, and cooling medium circulates in evaporation tube and dispels the heat, and reaches the effect of cooling.
As further improvement of the utility model, be provided with radiator between described radiator side and the lamp housing, described radiator is fixed on the radiator side, and the side that described radiator and radiator are connected is the plane, connect radiator in the radiator side, increase radiating effect.
As further improvement of the utility model, the evaporation plate two ends of described bending are connected by heat pipe, and heat pipe communicates with the evaporation tube at evaporation plate two ends, and adding needs heat pipe is vacuumized man-hour, insert cooling medium, the evaporation plate two ends are connected into the closed circuit that communicates by heat pipe again.
As further improvement of the utility model, described radiator is fixed on the lamp housing inboard by screw, and is provided with graphite flake between the stationary plane of radiator and lamp housing.
