Working Principle
U type solar collector bends a straight copper pipe to U-shape at a certainposition, and two ends of the copper pipe are parallel with one end higher thanthe other. The collector consists of waterchannel for U-shape pipe, insulation layer, vacuum tube and frame, and it alsocontains U-shape copper pipe and metal sheet. When the collector is working,sunshine passes through the outer tube, and the inner tube is exposed to thesunlight. The aluminum fin is connected closely to the inner tube, and ittransfers the heat absorbed by the vacuum tube to the U-shape copper pipe, andthen the heat is transferred to the working medium by the copper pipe. As aresult, the temperature of the working medium is becoming higher and higher,and then water in the tank is heated by absorbing heat transferred by themedium.

Features
1. Rigid connection methodis adopted by our U type solar collector, so the ageing and leakage phenomenacaused by the silicone seal are avoided
2. The water doesn’t flow through the vacuum tube, thus scaling problem isprevented. Furthermore, the heat collecting efficiency won’t be reduced afterlong-time service.
3. The installation angle won’t affect the mounting method, and this machine can be fixed horizontally or vertically which meansthat it can be hanged on the balcony as well.
4. Our product can be used as the non pressure type or pressurized type and thewhole system is still able to work even if one vacuum tube is broken.
5. Forced heat transfer via liquid is achieved by the circulating pump, and theheat transfer efficiency is very high.
6. The solar collectors can be assembled together by series and parallelconnections to form big scale heat collecting project.

Five models of U type solar collector are availablenow, and they have the same length and height whose specific values are 1970mmand 136mm, respectively. On the other hand, the width is different, and thenumbers are 88mm, 103mm, 1268mm, 1493mm and 1643mm. Among these models, thesmallest aperture area is 0.87m2 while the number of the biggest onecan reach up to 1.73m2. JNSC-58-1800-10Utakes up a volume of 0.273m3, and a 40'HG container can load 249 sets of this model while itcan only load 136 sets of JNSC-58-1800-20Uunder the same condition.
