Description

Technical Field

[0001] This utility model relates to the field of solar energy protection technology, and in particular to an overheat protection device for a solar heating collector system. Background Technology

[0002] Solar heating systems collect solar energy and convert it into heat to provide warmth to buildings. However, using overheated water for heating can result in water that is too hot to meet indoor heating needs, wasting energy and affecting heating comfort. To address these adverse effects caused by overheating and ensure the safe, stable, and efficient operation of solar heating systems, overheat protection devices for solar heating systems have been developed.

[0003] However, in actual operation, the system has a significant problem: when there is sufficient sunlight for a long period of time, the solar collector continuously absorbs solar energy and converts it into heat energy, causing the water temperature in the system to rise continuously. If the water temperature is too high, on the one hand, it will accelerate the aging and damage of components such as pipes and valves in the system, reduce the service life of the system, and increase maintenance costs; on the other hand, high temperature may cause water in the pipes to vaporize and generate high pressure, posing a safety hazard of pipe bursting and threatening the safety of buildings and personnel.

[0004] Therefore, we provide an overheat protection device for solar heating collector systems to solve the above problems. Utility Model Content
