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 "the

Embodiment 1

[0009] This embodiment adopts water-passing vacuum heat collecting pipes, the appearance of the existing widely used solar water heaters, the arrangement of the water pipe array and the bracket are unchanged, the water tank is equipped with power generation components inside and outside, and the maintenance-free battery is placed under the bracket, as attached figure 1 Shown. According to the local climate, sunshine conditions, number of vacuum collector tubes and power demand, the battery voltage can be 6-12 volts, with a capacity of 100-200 AH. An electric heating wire is installed in the water tank, and the battery voltage is turned on by a switch to heat water, which provides a large amount of water. , When the temperature is not enough or there is no sun at night, as a fixed family member, the water time can be selected reasonably. The inside of the water tank is made of insulation material such as polyurethane, and the water tank is divided into two parts. The upper end of ...

Embodiment 2

[0011]In this embodiment, the vacuum heat collection tube has a water-impervious structure, and each vacuum heat collection tube has a heat superconductor. Because the vacuum heat collection tube is separated from water, there is no dead water in the tube, and it will not be corroded by scale. It transfers heat in one direction with small heat capacity and heat transfer. Fast speed, fast heating, good low-temperature resistance, and will not freeze and crack at a low temperature of -50 ℃. The medium in the tube is made of inorganic elements and the operating pressure is low. The tube wall is high temperature to 200℃, and there is no danger. After the thermal superconductor is extended from the collector tube, it is connected to the hot end of each semiconductor thermoelectric power generation module located at the lower part of the water tank through a copper joint. The corresponding cold end is connected to the radiator and each power generation module The hot end is formed into ...

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...
