Tube heat exchanger gas-gas heat exchange experimental device

1. The entire device is beautiful and generous, the structure is reasonable, the overall sense is strong, and has a strong engineering atmosphere, which can fully reflect the concept of modern laboratories.

2. The device is a self -propelled frame structure, and the feet are installed, which is convenient for the system's disassembly, m--ntenance and handling, and reflects the perfectness of the entire device.

3. The test device of the heat coefficient measurement is based on the hot and cold --r as the medium. The gas-gas exchange thermal system is used, the data measurement is accurate, the experimental effect is ideal, and the degree of automation is high.

4. The device uses a tube heat exchanger for hot and cold gas to change heat. The cold --r uses --r instead of water, saving water resources. The design of the dual fan owner and deputy circuit design, the switching of the heating process ag--nst the current, is closer to the reality of industrial applications.

5. Use the thyristor pressure regulating module to control the power of heating room. Multiple sets of U -shaped fins heating pipe preheating system, fast and uniform heating speed, platinum heat resistance+thyristor+heating pipe as the m--n control method of thermal flow temperature Essence

6. Device design can be observed at 360 degrees to achieve comprehensive teaching and experiments.
