Title
(EN) Vapor chamber
(ZH) 均温板
Abstract
(EN) The utility model provides a vapor chamber which is internally provided with a closed space filled with working liquid, the vapor chamber comprises a first cover plate, a second cover plate and a supporting middle frame, the first cover plate and the second cover plate are oppositely arranged, the supporting middle frame is clamped between the first cover plate and the second cover plate, and a plurality of through holes are formed in the supporting middle frame in a penetrating mode; the vapor chamber further comprises a capillary structure, and the capillary structure at least partially covers the through hole. Working liquid at the end, making contact with the heating area, of the vapor chamber is vaporized to absorb heat, heat of the heating area is taken away, the vaporized working liquid flows to the low-temperature end of the vapor chamber through the through holes, and the working liquid is liquefied at the end, making contact with the low-temperature structure, of the vapor chamber to release heat. And then the working liquid flows from one end in contact with the lower-temperature structure to one end in contact with the heating area from the capillary structure again, and the heat dissipation effect is achieved through the reciprocating circulation. And the supporting middle frame is arranged between the first cover plate and the second cover plate, and the strength of the vapor chamber can be enhanced through the supporting effect of the supporting middle frame.
(ZH) 本实用新型提供了均温板,均温板内部具有填充有工作液体的封闭空间,均温板包括相对设置的第一盖板、第二盖板以及夹设在第一盖板和第二盖板之间的支撑中框,支撑中框上贯穿开设有若干通孔;均温板还包括毛细结构,且毛细结构至少部分覆盖所述通孔。均温板与发热区接触的一端的工作液体汽化吸热,带走发热区域的热量,汽化后的工作液体通过通孔流向均温板的较低温度的一端,并且工作液体在均温板与较低温度的结构接触的一端液化放热,之后工作液体自毛细结构再次从与较低温度的结构接触的一端流向与发热区接触的一端,如此往复循环,实现散热作用。而且第一盖板与第二盖板之间设置有支撑中框,支撑中框的支撑作用,能够增强均温板强度。
