technical field

The utility model belongs to the technical field of solar heat collectors and relates to a novel solar heat collector header.

Background technique

In the face of increasingly intensified resource and environmental constraints and energy supply pressure, it is the current and future development trend of the energy industry to develop renewable energy, realize the replacement of old and new energy, and take the road of sustainable development. Because solar energy is clean, non-polluting, and inexhaustible, it fully meets the selection criteria for new energy under the current global energy crisis, and has become an important development strategy for global sustainable energy development. Most of China is located south of 45 degrees north latitude and has abundant solar energy resources. It is estimated that the annual solar radiation energy is 3340-8400MJ/m2, and the total solar radiation energy received by the land surface area of the country is equivalent to 1.7 trillion standard coal. In our country, solar water heaters are better promoted, which have a production and application history of more than 20 years in our country. With the continuous improvement of people's living standards, the surge in demand for domestic hot water has promoted the rapid development of the solar water heater market.

A solar collector is a device that converts the sun's radiant energy into heat energy. Although the solar collector is not a terminal product directly facing consumers, the solar collector is a key component of various solar heat utilization systems. A solar heat collector generally includes a header and a vacuum tube connected to the header, and an inner tank is arranged inside the header. There is a certain angle difference between the existing vacuum tube socket and the end box, that is, the vacuum tube is arranged obliquely. However, the cross-section of the existing liner is generally rectangular. When the socket of the vacuum tube is connected to the liner, the angle difference of the vacuum line needs to be changed by the elasticity of the sealing ring. Therefore, the vacuum tube will cause abnormal pressure on the sealing ring, which will cause uneven force on the sealing ring. After a certain period of time, the sealing ring will easily lose its elasticity, which will lead to water leakage.
