Definitions

  • the present invention relates to a brass alloy, and more particularly to a brass alloy for use in the manufacture of air conditioning dispensers. Background technique
  • the dispenser is the component used in the air conditioning system to distribute the circulating medium.
  • the brass distributor structure for air conditioning has a large number of capillary holes arranged in the body, and the capillary has a small aperture, and some of the small holes have a diameter of only ⁇ 3 mm. A large number of such capillary holes are often arranged on a small end face, and these capillary holes are capillary tubes by welding a thin copper tube. If the brass alloy does not have good brazing properties, it is easy to cause problems such as soldering. For brass alloys to have good brazing properties, brass alloys are required to have good wettability. When the brazing temperature is reached, the brass alloy can automatically adsorb the intermediate materials.
  • the existing brass alloys are made of high temperature mixed surfaces of copper, zinc and lead. The disadvantages of this alloy are: poor wettability, and easy soldering during welding, which affects the yield of the product. Summary of the invention
  • the invention solves the problems that the existing brass alloy distributor has poor wettability when welding the capillary tube, is easy to produce virtual welding, and affects the product qualification rate.
  • the technical solution adopted by the invention is: a brass alloy for manufacturing an air conditioner dispenser, which is melted and mixed according to the following mass ratio: copper 55% - 65%, zinc 32% - 40%, tin 1.5% - 2%.
  • the brass alloy obtained by the above technical solution has no wet soldering because of its good wettability.
  • the advantageous effects of the present invention are as follows: Since the brass alloy of the present invention has good wettability, there is little occurrence of a virtual soldering phenomenon when the capillary is welded, and thus the yield of the product is high. detailed description
  • the invention relates to a brass alloy for manufacturing an air conditioner distributor, which is mixed with copper 60%, zinc 38% and tin 2% at a high temperature and then cooled to obtain a brass alloy.

Description

说明书
一种制造空调分配器用的黄铜合金 技术领域
本发明涉及一种黄铜合金， 尤其是一种制造空调分配器用的黄铜合金。 背景技术
分配器是空调系统中用来对循环介质进行分配的部件。空调用黄铜分配器结构是在实 体上排列着众多的毛细孔， 毛细管的孔径很小， 有的小孔仅有 Φ 3毫米的径。 在一个很小 的端面上往往排列着众多这样的毛细孔， 这些毛细孔都是通过焊接上细铜管成为毛细管 的。如果黄铜合金不具备良好的钎焊性能， 那么极易造成虚焊等现象。黄铜合金要具备良 好的钎焊性能， 就要求黄铜合金具有良好的浸润性， 当钎焊的温度达到后， 黄铜合金即可 自动吸附焊接中间物质。现有的黄铜合金都是由铜、锌和铅高温混合面成。这种合金的缺 点是： 浸润性不好， 焊接时易产生虚焊， 影响产品的合格率。 发明内容
本发明就是解决现有黄铜合金分配器在焊接毛细管时由于浸润性不好，易产生虚焊， 影响产品合格率的问题。
本发明采用的技术方案是：一种制造空调分配器用的黄铜合金，它按如下质量比高温 熔化混合构成： 铜 55%— 65%、 锌 32%— 40%、 锡 1.5%— 2%。
采用上述技术方案所得的黄铜合金， 由于浸润性好， 因此不会产生虚焊。
本发明的有益效果是： 由于本发明所的黄铜合金， 浸润性好， 在焊接毛细管时， 产 生虚焊现象很少， 因此产品的合格率高。 具体实施方式
本发明一种制造空调分配器用的黄铜合金， 按铜 60%、 锌 38%、 锡 2%高温混合后冷 却制得黄铜合金。
