Heat absorption and heat storage integrated water heater with square inner container

Abstract

The invention discloses a heat absorption and heat storage integrated water heater with a square inner container. The heat absorption and heat storage integrated water heater comprises a box, a water inlet pipe and a water outlet pipe and is characterized in that double-layer tempered film-coated vacuum plate glass is fixedly arranged on the open edge of the box, the heat storage inner container is arranged in a cavity of the box, and the water inlet pipe and the water outlet pipe are arranged on the side walls of the heat storage inner container and communicated with an inner cavity of the heat storage inner container; the heat storage inner container is formed by oppositely buckling an inner half shell and an outer half shell together and fixing the inner half shell and the outer half shell through bolts, and a heat absorption layer is arranged on the outer wall of the outer half shell. The heat absorption and heat storage integrated water heater has the good heat preservation performance and heat collecting performance, and can run in a pressure-bearing manner and a non-pressure-bearing manner, and the water heater can be used in a full-weather and all-terrain manner without limitations. Simple and reliable industrial production can be achieved, and marketization and industrialization high-temperature heat utilization and popularization can be achieved.

Description

technical field [0001] The invention relates to the improvement of a solar water heater, and belongs to the field of solar heat utilization, in particular to a water heater integrated with a square inner tank for heat absorption and heat storage. Background technique [0002] Before the mid-1990s, solar water heaters were only in the scientific research stage, and a small number of sun-dried solar water heaters and flat-plate solar collectors appeared. However, due to poor insulation and large heat loss, the heat collection performance is poor and the thermal efficiency is not high, especially in winter, it is easy to freeze. Therefore, a mainstream market has not been formed. At the end of the 1980s, Professor Yin Zhiqiang of Tsinghua University invented the aluminum-nitride-aluminum coating and the all-glass vacuum solar collector tube, which solved the problems of poor thermal performance, poor heat preservation, and freezing in winter in the early sweltering solar water...

AI Technical Summary

Problems solved by technology

For the all-glass vacuum heat collector tube solar water heater or heat collector, its disadvantages are: 1. It cannot be used in medium and high-rise buildings; 2. There are gaps between the heat collector tubes, which seriously limit the outline of the solar water heating system. 3. The vacuum tube cannot continue to be used after it bursts; 4. Ordinary all-glass vacuum solar collector tubes cannot operate under pressure and require a separate water tank, which increases the cost of installation and maintenance

However, the deficiencies of the flat solar water heaters currently used in middle and high-rise buildings are: 1. The thermal efficiency is extremely low; short life
