Automatic high-efficiency power generation solar water heater

Abstract

The invention provides an automatic high-efficiency power generation solar water heater, and belongs to the field of solar energy utilization. For improving the utilization rate of solar energy and heat energy, a widely used monofunctional solar water heater is improved to first ensure a certain amount of hot water for bathing, then automatically use heat energy for high-efficiency power generation without manual operation, and finally store power in a storage battery for heating the water in a water tank when the temperature of the water is low or at night as well as lighting domestically and supplying power to televisions, computers, and the like. Usually, the solar water heater can generate more than one kilowatt-hour of the power in summer, and is an unexpected gift for the floating herdsmen. An evacuated solar collector tube with or without water can be used; for improving the efficiency of thermo-electric generation, large temperature difference is required; the water tank is divided into a large part and a small part; a temperature memorizing alloy push rod pushes an isolating baffle to open or close a water pass between the two parts to allow the temperature of the small amount of water in the small part to rise quickly; and heat is led out by a Qu inorganic superconduct heating pipe. Given popularization across China, the solar water heater has the power generation potential far more than that of the Three Gorges Dam.

Description

Technical Field: [0001] The invention belongs to the field of solar energy utilization, and is a device that utilizes solar thermal radiation to efficiently generate electricity and heat water. Background technique: [0002] Energy-saving and environmental protection is a major issue that people around the world are generally concerned about. The sustainable development of circular economy mode pays special attention to the use of renewable energy, and the development and research of solar energy everywhere is the first. Nowadays, the development and utilization of solar energy in China is mostly concentrated on solar water heaters. my country is a big producer and application country of solar water heaters. According to statistics at the end of 2006, there are about 5,000 production plants in the country with a total output of 90 million square meters, but most It is installed and used independently by each household and only produces hot water for daily life. Although in the pa...

Problems solved by technology

Although in the past 20 years, the quality of water heater production process has been continuously improved and the cost has been reduced, but the thermal energy utilization rate of solar water heaters and many defects in the promotion have not attracted the attention and improvement of the same industry at home and abroad.

As we all know, the thermal conductivity of silver is the highest among metals, so it is called "thermal superconductivity", which is named after the resistance of "electrical superconductivity" tends to zero. Thermal superconductors are used in the heat conduction and heat dissipation process of thermoelectric power generation It is the perfect combination of the present invention. Of course, it is also possible to use organic heat pipes, such as gravity heat pipes, which are less efficient and inconvenient to install.
