The difference between solar tubes 58 and 47
The difference between solar tubes 58 and 47 lies in the inner diameter; the difference between long and short tubes is only in the contents of the tube;
The winter temperature in the northeast is very low, so you need to choose good quality, which basically has nothing to do with 58, 47 or length. It is more suitable to use solar energy from heat pipes. It has strong heat absorption capacity, high thermal efficiency and better airtightness than ordinary all-glass vacuum heat absorption tubes, but the price is much higher. »
Solar vacuum tubes are the essential components of solar water heaters and are known as the “heart” of solar water heaters. The quality of vacuum tubes directly affects the lifespan and performance of solar water heaters. The rapid development of the industrytrie solar is also behind the development of vacuum tube companies:
On the one hand, the patented technology surrounding vacuum tubes is constantly innovating.
On the other hand leaves, the void. tube companies and production lines have increased in recent years
Solar water heaters generally have several tubes, and most of them are market tubes
The diameters of solar vacuum tubes. are 47, 58, 70, 125, 250, etc., and the length is 1200,1500.1600.1660.1800.2100, etc. The main ones in the market are 47.58 and the main lengths are 1500.1800. when the volume of the water tank remains unchanged, it is better to buy a conventional solar tube, it is easy to buy vacuum tubes in the market during maintenance.
Nowadays, solar tubes are generally 18, 20, 24, 30 and 36 tubes on the market. If you want more, you can choose to makethe project. Some brands have 15, 19 and 21. But as all solar professionals know, the big brands don't have them. Most current solar panels are photovoltaic. They are equipped with electric heating, but it always depends on the region you are in. If you are in the north or the Sichuan and Chongqing regions, you must have electric heating. , but other places may not need it.
