There is a yellow tube in Himin solar vacuum tube. What is this?

That is a copper heat pipe patented by Huang Ming. Vacuum copper tube with copper content as high as 99.99% and filled with specific working medium (copper material is provided by Roton Group, and its products are only supplied to several big companies such as Huang Ming and Siemens, which are hard to buy in the market). It is a thermal superconductor and the most effective heat transfer element that people can master at present. In winter, the starting temperature of heat pipe is low and the heat transfer speed is fast. There is also:

1, heat transfer depends on the heat pipe in the vacuum tube, and there is no water running in the tube when working;

2, the tube does not freeze at -40℃, so the cold-proof performance is more outstanding, and there is no worry about freezing three feet;

3, the accidental damage of a single vacuum tube does not leak, and does not affect the use of the whole machine; No hidden danger of water leakage and icing;

4. There is no water and no scaling in the tube;

5, cold and hot shock resistance, can be filled with water at any time, without tube explosion;

It is most suitable for use in cold areas of Northeast China. You'd better go to official website, Huang Ming to consult the customer service in Huang Ming, and they will choose a solar energy that suits you best.

I hope it helps you, and I wish you a happy life! :)
