Brief introduction of company:

Our company specializes in the production of all glass vacuum collector tubes of large enterprises. The company has more than the most advanced high-vacuum exhaust automatic vacuum coating stations and fully automatic production lines, advanced laser marking anti-counterfeiting technology, micro-computer controlled plating technology, leading suction / exhaust technology, the company set annual production and sales of vacuum heat pipe. 

About Solar Collector:

The solar collector  consists of the collector, working stationand the water tank. The collector applied solar copper heat pipe and can quikely transfer solar energy into the superconducting liquid and  heat the water through the exchanger. The solar copper heat pipe is a perfect conbination of  vacuum tube and heat pipe. Advanced heat transferring style of the heat pipe, excellent selective absorbent coating and perfect combination with high vacuum heat preservation make the solar collector high absorbing efficiency.

Specifications:

1. Vacuum tube: 58/1800 heat pipe solar vacuum tube

2. Copper header inside: 0.8mm thick red copper header inside

3. Outer shell: 1.6mm thick aluminum alloy outer shell

4. Insulation: 35mm thick polyurethane foam insulation

5. Bracket: 45 degree 1.5mm thick galvanized sheel steel

6. Size:120mm*115mm

7. Application:split solar water heating system

Work Principles:

1.  When the temperature difference between the solar collector and tank is exceededthe set value temperature difference, the controller shall start the circulationpump automatically, transfer heat from collector to tank;

2.  When the temperature difference between the solar collector and tank drops belowthe set value temperature difference, then circulation pump stop;

3. The circulation pump makes heat-conducting liquid circulate automatically;

4. The heat-conducting liquid transfers heat to water by heat exchanger in the watertank;

5. In case the temperature of the water tank does not reach the max., then startthe auxiliary heating device.
