Description
Technical field
It the utility model is related to great power LED light path technical field of heat dissipation, and in particular to a kind of great power LED light path dissipates
Hot combined system, more particularly to a kind of great power LED light path and the cold heat radiation combination system of liquid cold wind.
Background technology
LED has small volume, long lifespan, luminous efficiency is high, and energy-conserving and environment-protective etc. are excellent as a kind of new solid-state cold light source
Point.Great power LED is to study one of focus of application in recent years, high-power after especially great power LED chip occurs
LED, which is applied to lighting field, greatly the trend for substituting traditional lighting.But current LED still suffers from driving power design, light path is set
The problem of in terms of meter and heat dissipation design.
In terms of radiating, the heat transfer of high-power LED light source is the heat transfer process that material is occurred under temperature difference effect,
No matter between an interior of articles or some objects, simply by the presence of the temperature difference, heat just will be with a certain or certain several ways
Spontaneously it is transmitted at high temperature at low temperature.Heat transfer has three kinds of basic modes：Heat transfer (heat conduction), thermal convection current, heat radiation.With
Conventional light source is compared, and LED outstanding feature is small volume, compact-sized, convenient embedded various light fixtures, as the carrier of light source,
It is most important that the heat dissipation design of light fixture plays LED its advantage.If the radiating efficiency design of light fixture is higher, can not only extend
LED service life, the weight of light fixture can also be mitigated, expand its application.Conversely, the performance of LED advantages can be then influenceed,
Even as the bottleneck of its application.
The radiating mode that we know at present generally has two kinds：The first is active radiating, that is, passes through additional fans, water
Methods of Forced refrigerating such as cold or heat pipe circuit, microchannel refrigeration, conductor refrigeration etc. are radiated, and are characterized in radiating
Efficiency high, radiator small volume are compact-sized；Shortcoming is to increase extra power consumption, and has degree of protection in view of light fixture
Deng requiring, it can also increase the difficulty of Design of Luminaires, it is existing how more normal in the method for air-cooled (additional fans) in this kind of radiating mode
See, the mode of water-cooling is because the limitation of light fixture volume and structure is using less.Second is passive heat radiation, is relied primarily on
The free convection of air, heat caused by thermal source is dispersed into air naturally by fin, its effect to radiate and radiating
Piece size is related；This mode is simple in construction, but radiating efficiency is than relatively low, but for illuminator, is dissipated due to this kind
Hot mode is easily combined with fitting structure, and structure is relatively simple, and does not need extra power consumption, while for adding
Work, material cost, maintenance factor etc. consider, thus it is using the holistic cost passively to radiate relatively low, therefore
Main flow direction still takes the second way at present, meets dissipating for illuminator to greatest extent by rationally designing radiator
Heat request, at the same it is cost-effective to greatest extent.
At present, light trade is radiated using heat-pipe radiator to LED light source (including integrated optical source and die set light source)
Mode it is very universal, however, with the continuous lifting of LED light source power, heat-pipe radiator technology is as that need to meet super large
Just only increase heat pipe quantity and fin area meet for power LED light source radiating, promote the length and width of heat-pipe radiator,
High and weight degree all accordingly increases, and further has influence on all many-sides such as volume and the holistic cost of light fixture.Therefore need grind
A kind of brand-new radiating mode is studied carefully to adapt to the needs of high-power LED light source development.
