 散熱是影響LED燈具照明強度的一個主要要素。led燈具比傳統的白熾燈能效高80%，但是其LED組件和驅動器電路散熱量很大。假如這些熱量沒有恰當的排放進來，LED燈具的發光度和壽命將會急劇降落。
Heat dissipation is one of the main factors that affect the lighting intensity of LED lamps. LED lamps are 80% more efficient than traditional incandescent lamps, but their LED components and drive circuits have a large amount of heat dissipation. If the heat is not properly discharged, the lighting and life of the LED lamp will drop sharply.
散熱片能處理低照明度LED燈具的散熱問題。燈具廠商能消費40W LED替代燈以及60W LED替代燈。高照明度LED燈具就會遇到散熱問題。一個散熱片是無法處理75W或者100W LED燈具的散熱問題的。
Heat sink can deal with the problem of low brightness LED lamp cooling. Lamp manufacturers can consume 40W LED replacement lamps as well as 60W LED replacement lamps. High brightness LED lamp can meet the heat problem. A heat sink is not able to deal with 75W or 100W LED lamp cooling problem.
對高亮度燈泡的需求顯而易見，75W和100W燈泡占領了照明市場很大份額。市場都盼望應用LED燈具固有的節能和維修優勢。2007年的美國能源獨立和平安法案請求從2012年起運用更高效率的照明燈具。這些新請求促使消費者們尋覓照明質量好、壽命高并且照明度強的燈具來替代現有的白熾燈。
The need for high brightness bulbs is obvious, 75W and 100W bulbs occupy a large share of the lighting market. The market is looking forward to the application of LED lamps inherent energy saving and maintenance advantages. The energy independence and security act of 2007 requires the use of more efficient lighting fixtures from the year of 2012. These new demands prompt consumers to look for better lighting, high quality and high lighting to replace the existing incandescent lamps.
為了到達理想的照明強度，必需運用主動冷卻技術來處理LED 燈具組件釋放的熱量。一些主動冷卻處理計劃例如風扇的壽命沒有LED燈具高。為了給高亮度LED燈具提供一個適用的主動冷卻處理計劃，散熱技術必需是低能耗的；并且能適用于小型燈具；其壽命要與燈源類似或高于燈源。
In order to achieve the desired lighting intensity, active cooling technology must be used to deal with the heat release of the LED lamp assembly. Some active cooling treatments such as fan life are not LED high. In order to provide a suitable active cooling treatment plan for high brightness LED lamps, the heat dissipation technology must be low energy consumption, and can be applied to small lamps.
散熱方式
Cooling mode
普通說來，按照從散熱器帶走熱量的方式，能夠將散熱器分為主動式散熱和被動式散熱。所謂的被動式散熱，是指經過散熱片將熱源LED光源熱量自然分發到空氣中，其散熱的效果與散熱片大小成正比，但由于是自然分發熱量，效果當然大打折扣，常常用在那些對空間沒有請求的設備中，或者用于為發熱量不大的部件散熱，如局部提高型主板在北橋上也采取被動式散熱，絕大多數采取主動式散熱式，主動式散熱就是經過風扇等散熱設備強迫性地將散熱片發出的熱量帶走，其特性是散熱效率高，而且設備體積小。
Generally speaking, in accordance with the way to remove heat from the radiator, the radiator can be divided into active and passive heat dissipation. The so-called passive cooling, is a heat sink heat source LED natural light source heat distribution into the air, the cooling effect and the heat sink is proportional to size, but because it is natural to distribute heat, greatly reduced the effect of course, often with no request in those of space equipment, or for small heat radiating parts, such as local improvement board also take passive cooling in Beiqiao, most take active cooling type, active cooling fan cooling device is through forced to take the heat from the heat sink, its characteristic is the high thermal efficiency, small volume and equipment.
主動式散熱，從散熱方式上細分，能夠分為風冷散熱、液冷散熱、熱管散熱、半導體制冷、化學制冷等等。
Active cooling, heat dissipation from the way of segmentation can be divided into air cooling and liquid cooling, heat pipe cooling, semiconductor refrigeration, refrigeration and chemical etc..
風冷風冷散熱是最常見的散熱方式，相比擬而言，也是較低價的方式。風冷散熱從本質上講就是運用風扇帶走散熱器所吸收的熱量。具有價錢相對較低，裝置便當等優點。但對環境依賴比擬高，例如氣溫升高以及超頻時其散熱性能就會大受影響。
Cold air cooling is the most common way of heat dissipation, compared to the intended, but also cheaper way. Air cooling is essentially the use of fans to take away the heat absorbed by the radiator. It has the advantages of relatively low price and convenience. However, the high dependence on the environment, such as the temperature rise and the heat dissipation performance of overclocking will be greatly affected.
液冷
Liquid cooling
液冷散熱是經過液體在泵的帶動下強迫循環帶走散熱器的熱量，與風冷相比，具有安靜、降溫穩定、對環境依賴小等等優點。液冷的價錢相對較高，而且裝置也相對費事一些。同時裝置時盡量依照闡明書指導的辦法裝置才干取得最佳的散熱效果。出于本錢及易用性的思索，液冷散熱通常采用水做為導熱液體，因而液冷散熱器也常常被稱為水冷散熱器。
Liquid cooling is through the liquid in the pump driven by forced circulation away the heat of the radiator, and compared with air cooling, cooling, quiet and stable advantages of less dependence on the environment and so on. Liquid cooling price is relatively high, and the device is relatively some trouble. At the same time, the device as far as possible in accordance with the instructions of the book to guide the device to achieve the best cooling effect. For cost and ease of thinking, liquid cooling usually adopts water as the heat transfer liquid, and the liquid cooling radiator is also often called a water-cooled radiator.
熱管
heat pipe
熱管屬于一種傳熱元件，它充沛應用了熱傳導原理與致冷介質的快速熱傳送性質，經過在全封鎖真空管內的液體的蒸發與凝結來傳送熱量，具有極高的導熱性、良好的等溫性、冷熱兩側的傳熱面積可恣意改動、可遠間隔傳熱、可控制溫度等一系列優點，并且由熱管組成的換熱用具有傳熱效率高、構造緊湊、流體阻損小等優點。其導熱才能已遠遠超越任何已知金屬的導熱才能。
Heat pipe is a heat transfer element, it makes full use of rapid thermal heat conduction principle and cooling medium transmission properties, after full blockade in the vacuum tube of the liquid evaporation and condensation heat transfer, heat transfer surface has high thermal conductivity, good thermal and isothermal on both sides of the product can be arbitrary changes and far the interval of heat transfer, a series of advantages can control temperature, and heat transfer in tube has the advantages of high heat transfer efficiency, compact structure, small fluid resistance loss is composed of heat. Its thermal conductivity is far beyond any known metal thermal conductivity.
半導體制冷
Semiconductor refrigeration
半導體制冷就是應用一種特制的半導體制冷片在通電時產生溫差來制冷，只需高溫端的熱量能有效的分發掉，則低溫端就不時的被冷卻。在每個半導體顆粒上都產生溫差，一個制冷片由幾十個這樣的顆粒串聯而成，從而在制冷片的兩個外表構成一個溫差。應用這種溫差現象，配合風冷/水冷對高溫端停止降溫，能得到優秀的散熱效果。半導體制冷具有制冷溫度低、牢靠性高等優點，冷面溫度能夠到達零下10℃以下，但是本錢太高，而且可能會因溫渡過低招致形成短路，而且如今半導體制冷片的工藝也不成熟，不夠適用。
Semiconductor refrigeration is the use of a special semiconductor cooling chip in the power to produce a temperature difference to cool, just the high temperature side of the heat can be effectively distributed out, then the low temperature side of the cooling from time to time. A temperature difference is generated on each of the semiconductor particles, and a refrigeration sheet is formed in series by a plurality of such particles, thereby forming a temperature difference between the two surfaces of the refrigerator. The application of this temperature difference phenomenon, with the air / water cooling to stop the high temperature side, can get excellent cooling effect. Semiconductor refrigeration with refrigeration temperature is low, the reliability is high, the surface temperature can reach 10 degrees below zero, but the cost is too high, and may be formed through the low temperature lead to short-circuit, and now the technology of the semiconductor refrigeration piece is not mature, not applicable.
化學制冷
Chemical refrigeration
所謂化學制冷，就是運用一些超低溫化學物質，應用它們在消融的時分吸收大量的熱量來降低溫度。這方面以運用干冰和液氮較為常見。比方運用干冰能夠將溫度降低到零下20℃以下，還有一些更“變態”的玩家應用液氮將CPU溫度降到零下100℃以下(理論上)，當然由于價錢昂貴和持續時間太短，這個辦法多見于實驗室或極端的超頻喜好者。
The so-called chemical refrigeration, is the use of some ultra-low temperature chemical substances, the use of them in the ablation of the absorption of large amounts of heat to reduce the temperature. In this regard, the use of dry ice and liquid nitrogen is more common. For example, using dry ice temperature can be reduced to below 20 DEG C, there are some more "abnormal" game player will CPU the application of liquid nitrogen temperature dropped to minus 100 degrees Celsius (in theory), of course, because of the cost and duration is too short, this way in the laboratory or extreme overclocking enthusiasts.
