1. Product Introduction
Sunflower's heat pipe(copper) is made of high-purity hollow copper tubes，at one end of the tube is a heat pipe bulb with larger diameter.First seal one end of the copper tube and inject a proper amount of high purity water into the tube.The copper tube is heated at a high temperature, and the air in the copper tube is discharged and sealed, and a vacuum is formed inside the copper tube.The purpose of creating a vacuum in the heat pipe(copper) is to lower the boiling point of the water.At standard atmospheric pressure, the boiling point of water is 100 ° C,but inside the heat pipe(copper) that has been drained, the boiling point of the water will drop to 30 °C.The starting temperature of the heat pipe(copper) is greatly reduced.
SFVB consists of a heat pipe(copper), a vacuum tube, an aluminum fin and a silicone plug.
1.3 Working Principle
2. Features and Specifications
High speed and high efficiency on heat transfer.
Low start-up temperature on heat energy and better resistance against lower temperature ,obvious advantages on performance in low temperature and cold regions.
The round structure automatically tracks the sunlight, maintains high efficiency throughout the day with stable heat supply.
No water inside, no scale, which maintains efficient heat exchange for a long time.
Pressurized type, independent design,the disassembly and assembly does not affect the system operation.
3. Quality Reliability
Excellent welding and sealing process to maintain long-term high vacuum.
High-purity water can prevent the decomposition of impurities and produces non-condensable gases.
The installation angle and efficiency of the heat pipe are shown in the figure below. The best installation angle is 30°-60°.
4. Warranty and Certificate
5. Package and Transportation
The package design can be stacked and stored, but the base layer should be flat and evenly stressed. The maximum stacking level of the solar vacuum tube is 17 levels.
