Description

平板式热管
技术领域
本发明涉及一种热管，特别是指一种平板式热管。
背景技术
随着电子信息业不断发展，电子产品的集成度越来越高，其内的电子元件散发的热量也越来越多。业界通常将平板式热管用于电子元件散热。这种平板式热管通常包括一金属壳体、贴设于金属壳体内表面的毛细结构及注入金属壳体内的适量工作介质。因电子产品内部空间较小，平板式热管往往厚度较小。当这些平板式热管内部发生相变化时，其内部的液态工作介质与气态工作介质之间相互冲击导致飞散限制，影响液态工作介质的回流速度，从而影响平板式热管的散热性能。
发明内容
有鉴于此，有必要提供一种具有高散热效率且性能稳定的平板式热管。
一种平板式热管，包括一壳体、设置于壳体内壁的一毛细结构、容设于壳体内的工作液体，还包括抵顶壳体相对的二侧壁的若干隔板，每一隔板包括一连接板及自所述连接板凸设的若干间隔的凸起，每一凸起的一侧开设有一贯穿的通孔；所述若干隔板堆叠在一起，相邻隔板的通孔彼此连通，形成连通所述相对的侧壁的蒸汽通道。
本发明中堆叠设置的隔板，在不增加平板式热管体积的情况下，增长了蒸汽穿行路径的长度，从而降低了蒸汽流速，避免因蒸汽流速过快而冲击液态工作介质而导致的飞散限制，保障了平板式热管的稳定性。

具体实施方式
如图1及图2所示，本发明的平板式热管包括一底盖11、与该底盖11密封连接的一顶盖13、设置于底盖11及顶盖13内表面的、连续的一毛细结构15及夹设于底盖11及顶盖13间的若干隔板17。该底盖11呈碗状设置，其具有二相对设置的侧壁112及连接二侧壁112最下端的一底板114。该顶盖13为一纵长板体。隔板17夹设于顶盖13及底板114之间，且分别抵顶底板114及顶盖13的内表面的毛细结构15。
所述每一隔板17包括一连接板171及自连接板171一侧朝向同一方向凸设的若干凸起173。这些凸起173为内空的立方体且等距离间隔设置，其横截面呈梯形。可以理解的，这些凸起173的横截面可呈方形、三角形或其他几何形状。每一凸起173沿连接板171长度方向开设有一通槽175。连接板171位于每一凸起173正下方处开设有一通孔177。这些通孔177与通槽175共同形成一蒸汽流道，供平板式热管内的蒸汽流通。一隔板17沿连接板171宽度方向的一列凸起173抵顶相邻另一隔板17沿连接板171宽度方向的相邻两列凸起173之间的连接板171，从而使相邻二隔板17间的蒸汽流道交错设置，以增加蒸汽与隔板17的接触面积，加速蒸汽的冷却。可以理解的，一隔板17沿连接板171长度方向的一行凸起173抵顶相邻另一隔板17沿连接板171长度方向的相邻两行凸起173之间的连接板171或一隔板17相对相邻的另一隔板17转动一定角度的情况下，同样可以使相邻二隔板17间的蒸汽流道交错设置。
请再次参阅图1，使用时，平板式热管的底盖11的底板114吸收热量，并将这些热量传到至底板114内表面的毛细结构15，从而使毛细结构15内的工作介质发生相变化而形成蒸汽。这些蒸汽沿隔板17的通孔177向上运行，同时，自每一隔板17的通槽175流出并在相邻二连接板171形成的区域绕行，以与隔板17充分接触、交换热量，然后自通孔177向上运动，并最终液化而通过毛细结构15回流。本发明中堆叠设置的隔板17，在不增加平板式热管10体积的情况下，增长了蒸汽穿行路径的长度，使蒸汽与隔板17充分热交换，从而加速蒸汽液化并降低蒸汽流速，避免因蒸汽流速过快而冲击液态工作介质而导致的飞散限制，保障了平板式热管10的稳定性。
图3及图4所示，为本发明第二实施例平板式热管的隔板27。本实施例中隔板27的结构及排布均与第一实施例中隔板17相似，其区别仅在于：本实施例中的隔板27的凸起为内空的拱形，其横截面呈弧形。
图5及图6所示，为本发明第三实施例平板式热管的隔板37。每一隔板37包括一连接板371及自连接板371上下相对两侧朝向相反方向垂直凸设的若干对第一凸起373及第二凸起375。这些第一、第二凸起373、375间隔设置且均为方形片体。可以理解的，这些第一、第二凸起373、375可以为梯形、三角形或其他形状。第一、第二凸起373、375沿连接板的宽度方向间隔设置。每一对第一凸起373及第二凸起375之间形成有一方形的通孔377，以供蒸汽穿行。相邻二隔板37上下重叠设置，即每一第一凸起373的顶端抵顶相邻另一隔板37的第一凸起373的底端，每一第二凸起375的底端抵顶对应隔板37的第二凸起375的顶端，二隔板37的通孔377对应设置，从而使这些隔板37形成若干上下贯穿的蒸汽流道，从而使平板式热管内产生的蒸汽自下往上运动，增加与隔板37的接触面积，从而加速蒸汽的冷却。
可以理解的，一隔板37的第一凸起373及第二凸起375抵顶相邻一隔板37第一、第二凸起373、375之间的连接板371或一隔板37相对相邻的另一隔板37转动一定角度的情况下，同样可以使平板式热管内的蒸汽自下往上运动。
图7及图8所示，为本发明第四实施例平板式热管的隔板47。本实施例中的隔板47包括一连接板471及自连接板471一侧垂直凸设的若干对间隔的凸起473。隔板47的结构与排部方式均与第三实施例相似，其区别仅在于凸起473朝向同一方向设置。
图9及图10所示，为本发明第五实施例平板式热管的隔板57。本实施例中的隔板57包括一连接板571及自连接板571相对两侧朝向相反方向垂直凸设的若干间隔的凸起573。隔板57的结构与第三实施例相似，其区别仅在于凸起573为内空的拱形立方体，且其横截面呈弧形。本实施例中，相邻二隔板57中，一隔板57向上凸设的凸起573及另一隔板57向下凸设的凸起573沿连接板571的长度间隔设置，且分别抵顶另一隔板57沿连接板571宽度方向二凸起573之间的连接板571。
图11及图12所示，为本发明第六实施例平板式热管的隔板67。本实施例中的隔板67包括一连接板671及自连接板671相对两侧朝向相反方向垂直凸设的若干间隔的凸起673。隔板67的结构与排部方式均与第五实施例相似，其区别仅在于凸起673为内空的立方体，且其横截面呈梯形。
