It is best not to usea solar water heaterwhen it is raining or thundering. ?
Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet water usage hot water by people in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy is mainly based on vacuum tubes which use the principle according to whichwhere hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.
Working principle:
Sunlight passes through the first glass layer of the heat absorber tube and shines on the color black. of the second layer of glass. On the heat-absorbing layer, heat from solar energy is absorbed. Since both layers of glass are vacuum insulated, heat transfer will be significantly reduced (radiation heat transfer still exists, but it does exist). no thermal conduction and thermal convection).
Most of the heat can only be transferred to the water in the glass tube, causing the water in the glass tube to warm up. The heated water becomes lighter and moves upward along the heating surface of the glass tube. in the water storage bucket isolé. The temperature in the bucket is relatively high. The bottom water enters the glass tube along the backlight surface of the glass tube for replenishment. This continuous circulation causes the water in the insulated water storage bucket to continually heat. achieve the purpose of hot water.
