Solar water heater

Abstract

The invention discloses a solar water heater. The solar water heater comprises a water tank, a collector tube, a condensation plate, a support, a stop valve, an electric pump and a pipeline. The collector tube is arranged on the condensation plate sinuously. The two ends of the collector tube are provided with same pipeline joints correspondingly. The water tank is arranged on the ground below thecollector tube. The electric pump is arranged on the part, between the water tank and the collector tube, of the pipeline. The stop valve is arranged on the part, between the water tank and the collector tube, of the other side of the pipeline. The electric pump, the collector tube, the stop valve and the water tank are sequentially connected into a circulation loop through the pipeline in an endto end mode. The solar water heater is simple in structure, good in heat circulation performance and capable of heating water rapidly, and thus daily hot water supply of users is facilitated.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a solar water heater. Background technique [0002] With the development of Chinese society and the rapid development of industry, the natural fossil energy is becoming increasingly scarce, and environmental pollution is becoming more and more serious. Under this background, the photovoltaic industry is growing vigorously, alleviating the energy shortage and environmental pollution. develop. [0003] Solar energy is a renewable energy source. At present, the utilization methods of solar energy include: photothermal utilization, solar power generation, photochemical utilization, photobiological utilization, etc. Among them, the utilization of light and heat is to collect solar radiation energy and convert it into heat energy through the interaction with matter for utilization. At present, the most used solar energy collection devices mainly include three types: flat plate collectors...

AI Technical Summary

Problems solved by technology

However, existing solar water heaters have deficiencies in the design of their heat collecting tubes, water fetchers, and water supply devices, resulting in poor thermal cycle performance, poor effect of quickly obtaining hot water, poor antifreeze performance, and difficulty in descaling. Disadvantages such as inconvenient maintenance have greatly restricted its promotion and application

For example, solar vacuum heat collectors, due to the high temperature of hot water and serious scaling, are easy to be frozen and cracked in winter, and there are problems of mutual influence and interference between cold and hot water during convective exchange.
