Abstract

一种热管，包括一密封的壳体，该壳体包括一管体及连接于该管体一端的封口部，该管体由钛制成，该封口部由铜、铝、不锈钢、低碳钢、铁、镍、钨、钽、钼、铼或铌中的一种制成，既能使热管整体重量较轻，又能防止封口部在进行封口加工时产生裂纹，从而影响热管的导热性能。

Description

热管
技术领域
本发明涉及一种热管，特别是涉及一种质量轻且具有较好封口效果的热管。
背景技术
目前，由于热管具有较快的传热速度，而广泛应用于具较大发热量的电子元件的散热。现有的热管通常采用具有较高导热性的铜作为壳体，但随着多功能而又超薄型电子产品的出现，对散热装置的性能及轻量化的要求也越发提高，采用具有较高导热性且质量较轻的钛作为热管的壳体成为人们所追求的目标。然而，由于钛的硬度较高，使用该种材质作为壳体的热管在封口时容易产生裂纹，从而导致管体内的真空度及工作流体的泄漏，影响热管的导热性能。
发明内容
有鉴于此，有必要提供一种质量较轻且具有较好封合效果的热管。
一种热管，包括一密封的壳体，该壳体包括一管体及连接于该管体一端的封口部，该管体由钛制成，该封口部由铜、铝、不锈钢、低碳钢、铁、镍、钨、钽、钼、铼或铌中的一种制成。
所述热管的管体由质量较轻的钛制成，使热管整体重量较轻。同时，封口部由材质硬度较小，且延展性较好的材料铜、铝、不锈钢、低碳钢、铁、镍、钨、钽、钼、铼或铌制成，可以防止封口部在进行封口加工时产生裂纹，从而影响热管的导热性能。
附图说明
图1为本发明热管一实施例的立体图。
图2为图1所示的热管的纵向截面的示意图。
具体实施方式
下面参照附图结合实施例对本发明作进一步说明。
如图1及图2所示，该热管10包括一密闭的壳体11，该壳体11内封装有适量的工作流体(图未示)并于壳体11内壁或空腔内设有毛细结构12。
该壳体11包括一管体110及形成于该管体110一端的封口部112。
该管体110为由质量较轻的钛制成。该管体110的横截面为圆形。该管体110于靠近该封口部112的一端形成一缩管部115。该缩管部115包括靠近该管体110的一锥形部116及靠近该封口部112的一收容部117。该锥形部116的外径由该管体110的一端向靠近封口部112的方向逐渐减小，以使封口部112的横截面最小，而方便热管10的封口加工。该收容部117由该锥形部116的末端向该封口部112的方向延伸，且其外径不变。
该封口部112形成于该缩管部115远离该管体110的末端。该封口部112与该管体110是由相互分离的两个元件结合而成。该封口部112包括收容于该缩管部114的收容部117内的一连接部113及位于该收容部117外部的一密封部114。该连接部113的外壁与收容部117的内壁紧密接触，并于该收容部117的末端通过焊接与该连接部113相固定。该密封部114呈一压扁状，包括相互贴合的上、下管壁。该封口部112由硬度较低，且延展性好的材料，如铜、铝、不锈钢、低碳钢、铁、镍、钨、钽、钼、铼或铌制成，在热管10封口时，对封口部112进行夹扁封合操作，封口部112的材质硬度较小，且延展性较好，方便进行夹扁封口操作，避免了直接对钛管体进行夹扁封合操作。由于钛的加工性能不佳，与现有技术的整个壳体均由钛一体制造的热管相比，可以防止直接对钛管体进行夹扁封口加工时产生裂纹，从而导致壳体内的真空度及工作流体的泄漏，影响热管的导热性能。
