Problems solved by technology

At the same time, due to the large volume of the vacuum heat collecting tube, the thermal inertia is large, the water temperature rises slowly, and the heat loss is large, so the efficiency of the solar water heater is low.
Due to the large circulation area of ​​the vacuum heat collecting tube, the cold and hot water flow in the same direction in the opposite direction, and the rising speed of the hot water flow is slower. Heat Exchange Efficiency of Vacuum Heat Collector Tube

Abstract

The invention relates to a solar vacuum collector siphon cycle guider, which comprises a sealed guider, an upper support positioning device, a lower support positioning device, and a flow guider. It fills the tube chamber of solar vacuum heat collecting tube to form the solar energy water heater bank, the thermal-insulated falling water tube, the bottom coupled chamber, the heating ascending water tube and the water bank which form the closed cycle system. Wherein, the flow guider can guide the cold and hot water in or out of the tube, the coupled bank and the closed flow guider, to separate the descending cold water and ascending hot water; said closed flow guider is inside the heat collecting tube; and said invention at least comprises the upper and lower support positioning device, to support and position the closed flow guider inside the heat collecting tube.

Description

Technical field [0001] The invention relates to a thermal siphon circulation deflector for solar vacuum heat collecting tubes, which is mainly used in solar water heaters with all glass vacuum heat collecting tubes. Background technique [0002] At present, the vacuum heat collecting tubes of solar water heaters have the problems of being easily cracked by freezing in winter and that cold and hot water affect each other and interfere with each other during convective exchange. Especially for solar water heaters with reflection devices, after the water is heated, the rising hot water and falling cold water interfere with each other, affecting convective heat transfer and reducing the heat transfer efficiency of the vacuum heat collecting tube. Therefore, it is particularly important to improve the heat exchange efficiency of the vacuum heat collecting tubes to solve the problems of freezing and cracking of the vacuum heat collecting tubes in winter and mutual interference bet...
