熱管散熱技術原理及有優點

一.熱管散熱技術原理
  典型的熱管由管殼、吸液芯和端蓋組成,將管內抽成一定的負壓后充以適量的工作液體,使緊貼管內壁的吸液芯毛細多孔材料中充滿液體后加以密封。
  管的一端為蒸發段(加熱段),另一端為冷凝段(冷卻段),當熱管的一端受熱時吸液芯中的液體蒸發汽化,蒸汽在微小的壓差下流向另一端放出熱量凝結成液體,液體再沿多孔材料靠毛細力的作用流回蒸發段。
  如此循環不己,熱量由熱管的一端傳至另—端。
Typical heat pipe is composed of shell, suck liquid core and end cover, after pulling the tube into a negative pressure filling with just the right amount of working fluid, make the pipe close to the wall of capillary suction liquid core to be sealed after filled with liquid in porous materials.
One end of the tube for evaporation (heating), on the other side of condenser (cooling), when one end of the heat pipe heat absorption liquid evaporation vaporization of the liquid core, steam under tiny differential pressure gives off heat flow to the other end condense into liquid, liquid along the porous material by the effect of capillary force flow back to the evaporator.
So not himself, and the heat from one end of the heat pipe to the other side.
二.熱管散熱技術優點
1.與同樣體積型材散熱器相比散熱能力提升30%-50%,散熱效率高,產品單位面積輸出功率大,產品性價比高;
2.熱管散熱技術先進、生產工藝成熟、沒有特殊材料,產品性能穩定、產品可靠性高;
3.熱管散熱原理依靠物質自然相變過程,無需外部動力,因此系統構成簡單,較水冷、液冷等散熱系統無需強迫循環系統、甚至熱交換系統,應用領域更加廣泛;
4.產品維護等同于型材散熱器,維護簡單,減少后期成本。
1. Compared with the same volume profiles radiator cooling capacity increase of 30% - 30%, thermal efficiency is high, the product output per unit area is big, product cost-effective;
2. Heat pipe cooling technique, advanced production technology mature, no special materials, product stable performance, high reliability;
3. The principle of heat pipe radiator phase change process depend on the material nature, without external power, so the system is easy, the water cooling and surface cooling system without forced circulation system, and even heat exchange system, application field more widely;
4. Product maintenance is equal to profile radiator, simple maintenance, reduce the cost later.
