Description

Tankless solar heat storage rod

technical field

The utility model relates to a solar water heater assembly, in particular to a tankless solar heat storage rod, and belongs to the technical field of solar water heaters.

Background technique

Most of the existing solar water heaters integrated with buildings use balcony wall-mounted split-type solar energy; however, this product has inherent defects: 1. It has a water tank, which takes up space and is rejected; 2. Secondary and four-stage heat exchange, heat absorption The effect is poor and the water temperature is low; 3. The installation has angle requirements, which affects the facade; 4. The life of the water tank is short and easy to leak; 5. The medium must be replaced every two years, otherwise the system will be paralyzed; ; With the continuous development of science and technology, tankless solar products use high-performance PCM phase change energy storage materials, and put the energy storage materials into the solar heat collector tubes through the concentric sleeve parallel structure, so as to realize the after-heat collection of the solar heat collector tubes. It is an instant thermal pressurized solar collector; among them, its heat storage rod is the key component, while the existing heat storage rod Its heat transfer effect is not good enough, especially in the case of low sunlight, it is difficult to store heat well.
