Abstract

本发明涉及一种热管制作工艺。其特征在于制作工艺为：首先使用工具将外径 5mm 红铜管内部清除干净，去除毛刺，接着将铜管放到稀硫酸中使用超声波清洗，将一根细钢棍插到铜管里，用工具精确地将钢棍儿固定在铜管的中央，将铜管底部用铜片暂时封闭，把纯铜粉倒入铜管，装填完毕之后拿到烧结炉进行烧结，在烧结过程中，烧结炉峰值温度控制在 800～850 度，烧结完成之后使用一个辅助工具把铜管加紧，使用工具把钢棍抽出即可。本发明提供的铜粉烧结热管制作工艺，其有益效果在于，制作工艺简单，操作方便，容易控制，每个部分的毛细结构渗透率大致相同，铜粉烧结块分布厚度均匀。

Description

一种热管制作工艺
技术领域
本发明涉及一种热管制作工艺。
背景技术
烧结式热管，顾名思义，其毛细结构是通过高温下铜粉烧结制造而成的。目前铜粉烧结热管制作工艺复杂，不易控制，每个部分的毛细结构渗透率不一定相同，铜粉烧结块分布厚度不均匀。
发明内容
针对现有技术中存在的问题，本发明的目的在于提供一种热管制作工艺的技术方案。
所述的一种热管制作工艺，其特征在于制作工艺为：选取 99.5％纯度的铜粉，铜粉单体粒径控制在75～150 微米，首先使用工具将外径 5mm 红铜管内部清除干净，去除毛刺，接着将铜管放到稀硫酸中使用超声波清洗，将一根细钢棍插到铜管里，用工具精确地将钢棍儿固定在铜管的中央，将铜管底部用铜片暂时封闭，把纯铜粉倒入铜管，装填完毕之后拿到烧结炉进行烧结，在烧结过程中，烧结炉峰值温度控制在 800～850 度，烧结完成之后使用一个辅助工具把铜管加紧，使用工具把钢棍抽出即可。
本发明提供的铜粉烧结热管制作工艺，其有益效果在于，制作工艺简单，操作方便，容易控制，每个部分的毛细结构渗透率大致相同，铜粉烧结块分布厚度均匀。
具体实施方式
实施例
