100mm evacuated tube

Understanding the 100mm Evacuated Tube

The 100mm evacuated tube is a pivotal component in solar thermal technology, playing a crucial role in harnessing solar energy. These tubes are designed to minimize heat loss while maximizing energy absorption, making them an essential part of solar collectors.

Types and Applications

Evacuated tubes come in various types, each suited to different climatic conditions and applications. The heat pipe design is commonly used in residential solar water heaters, while the U-tube model is favored for industrial solar thermal systems due to its high-pressure resistance. Their applications span from domestic hot water supply to large-scale solar thermal projects.

Features and Materials

A 100mm evacuated tube is characterized by its cylindrical shape, with a vacuum layer acting as an insulator. The materials used, such as borosilicate glass and weather-resistant metals, are selected for their durability and thermal conductivity. These materials ensure the tube's ability to withstand environmental stress while efficiently converting solar radiation into heat.

Advantages of Using Evacuated Tubes

The advantages of using 100mm evacuated tubes in solar collectors are numerous. Their vacuum insulation reduces heat loss, which is especially beneficial in colder climates. Additionally, their round shape allows for a higher degree of solar absorption as they can capture sunlight from various angles throughout the day.

Selection Criteria for Evacuated Tubes

When selecting a 100mm evacuated tube, it is important to consider factors such as thermal efficiency, which dictates the speed at which the tube heats water, and durability, which affects the longevity of the system. The construction quality of the tube also influences its performance and maintenance requirements.
