Abstract

本实用新型是一种扩散吸收式制冷机芯的无焊接锥度缩管一体成型提升管，其内管采用无需焊接的锥度缩管一体成型技术，有效提高提升效率，延长制冷机芯的使用寿命。

Description

一种扩散吸收式制冷机芯无焊接锥度缩管一体成型的提升管
技术领域
本实用新型涉及一种扩散吸收式制冷机芯无焊接锥度缩管一体成型的提升管，尤其是内管采用无焊接、锥度缩管一体成型技术的提升管。
背景技术
目前，公知的扩散吸收式制冷机芯的提升管由三根铁管组成，外管是一根完整的铁管，内管由两根直径不同的铁管焊接而成。这样制成的提升管因内管大管与小管的连接是焊接而成的，所以内管表面不光滑、焊接处凹凸不平，在使用时影响提升管提升效率，并且内管焊接处附着有焊渣，提升管长期使用后容易堵塞，减少制冷机芯的使用寿命。
发明内容
为了提高提升管提升效率，延长制冷机芯使用寿命，本实用新型在制作提升管内管(2)时采用锥度缩管一体成型技术。提升管内管(2)由一根铁管经过锥度缩管一体成型后，提升管的内管下端(5)尺寸不变，内管上端(4)缩成小管，内管上端(4)与内管下端(5)连接处形成一个无焊缝的锥度连接区(3)。锥度连接区(3)表面光滑，提高提升管提升效率，避免提升管堵塞，有效延长制冷机芯使用寿命。
附图说明
图1为本实用新型的实施范例图，图2为公知的扩散吸收式制冷机芯的提升管制作图，图3为扩散吸收式制冷机芯图。
1-提升管外管
2-提升管内管
3-锥度连接区
4-内管上端
5-内管下端
6-焊接处
具体实施方式
本实用新型在制作提升管内管(2)时采用锥度缩管一体成型技术。提升管内管(2)由一根铁管经过锥度缩管一体成型后，提升管的内管下端(5)尺寸不变，内管上端(4)缩成小管，内管上端(4)与内管下端(5)连接处形成一个无焊缝的锥度连接区(3)。锥度连接区(3)表面光滑，提高提升管提升效率，避免提升管堵塞，有效延长制冷机芯使用寿命。
