Description

一种超薄热管
【技术领域】
本发明涉及一种热管。
【背景技术】
热管是具有高导热能力的装置。充填于热管内的液态介质在热区段汽化成蒸气，蒸气沿蒸气通道朝冷端高速移动；接着，在蒸气在冷区段凝结成液态介质，液态介质沿毛细构造在毛细作用下返回热区段。以此方式，可将热从热区段迅速传至冷区段。
随着电子产品的小型化薄型化，而对热管提出更高效的需求，需要有一种热效率更高的热管来满足产品的小型化集成要求。
【发明内容】
本发明目的是克服了现有技术中的不足，提供一种在金属管体内壁上设置沟槽结构的高热效率超薄热管。
本发明是通过以下技术方案实现的：
一种超薄热管，包括扁平的金属管体，其特征在于所述的金属管体的内壁上设有多个沿金属管体轴向延伸的沟槽形成的沟槽部，所述的沟槽部内侧紧贴设置有粉末烧结部，所述的粉末烧结部与光滑管壁之间形成蒸气通道空间。
如上所述的一种超薄热管，其特征在于所述的沟槽部为两个，分别位于金属管体内壁的两侧，两个沟槽部之间为光滑管壁。
如上所述的一种超薄热管，其特征在于所述的金属管体横截面两端为半圆形，所述的沟槽部设置在金属管体的平直侧壁上。
如上所述的一种超薄热管，其特征在于所述的两个沟槽部内侧的粉末烧结部连为一体。
如上所述的一种超薄热管，其特征在于所述的两个沟槽部内侧的粉末烧结部之间间隔开，两个粉末烧结部相正对。
如上所述的一种超薄热管，其特征在于所述的两个沟槽部内侧的粉末烧结部之间间隔开，两个粉末烧结部相交错
如上所述的一种超薄热管，其特征在于所述的沟槽部设置在金属管体截面的弯曲处。
如上所述的一种超薄热管，其特征在于所述的光滑管壁具有比沟槽部薄的厚度。
与现有技术相比，本发明有如下优点：
1、本发明在金属管体内壁上设置沟槽结构，导热性能好，热效率高；
2、本发明在沟槽部内侧设有粉末烧结部，辅助提高热管的导热性能。

【具体实施方式】
下面结合附图对本发明进行详细说明：
实施例1：如图1、图2、图6至图8所示，一种超薄热管，包括扁平的金属管体1，所述的金属管体1的内壁上设有多个沿金属管体1轴向延伸的沟槽2形成的沟槽部3。所述的光滑管壁101具有比沟槽部3薄的厚度。所述的沟槽部3为两个，分别位于金属管体1内壁的两侧，两个沟槽部3之间为光滑管壁101。所述的金属管体1为扁平金属管，金属管体横截面两端为半圆形，所述的沟槽部3设置在金属管体1的平直侧壁102、103上。所述的沟槽部3内侧紧贴设置有粉末烧结部4，所述的粉末烧结部4与光滑管壁101之间形成蒸气通道空间6。
本发明的扁平金属管体1是由圆管压扁，压扁时如正压在沟槽部3中央，压扁后所述的两个沟槽部3内侧的粉末烧结部4可被对正完全压合连为一体，上下对齐。
实施例2：如图1、图3、图6至图8所示，在压扁过程中，如果正压在沟槽部3中央，所述的两个沟槽部3内侧的粉末烧结部4未被完全压合，两个粉末烧结部4之间间隔开，两个粉末烧结部4相正对。
实施例3：如图1、图4、图6、图7所示，在压扁过程中，如压模正压在沟槽部3与光滑管壁101连接处，所述的两个沟槽部3内侧的粉末烧结部4就会被压成间隔错开，两个粉末烧结部4相交错
实施例4：如图1、图5、图6、图7、图9所示，在压扁过程中，如压模正压在光滑管壁101中央，所述的沟槽部3被弯折在金属管体1截面的弯曲处。
本发明的金属管体由铜、铝、不锈钢、钛或镍所制成。粉末烧结部由烧结铜粉、铝粉、镍粉或奈米碳粉而形成。
本发明的制作过程：首先取预留有沟槽部厚度的圆管拉沟槽或取等厚管壁的圆管拉沟槽后再拉去光滑管壁的内部材料；然后布烧结粉末；烧结；压扁。
