Heat collecting evaporator of steam box and solar water heater with the heat collecting evaporator

Abstract

The invention provides a steam box heat-collecting evaporator. The steam box heat-collecting evaporator comprises a thermal insulation shell and a sealed shell disposed in the thermal insulation shell. A thermal insulation layer is disposed between the bottom of the sealed shell and the thermal insulation shell. A glass cover plate covers the upper portion of the sealed shell. Steam collecting boxes are disposed on two sides of the sealed shell. A working medium collecting box with a top opening is disposed at the bottom of the sealed shell. A capillary structural layer is disposed on the working medium collecting box. A solar heat collector absorbs heat to evaporate working media entering the capillary structural layer so as to supply heat. The invention further provides a solar water heater with the heat-collecting evaporator, the heat-collecting evaporator is communicated with a water storage tank through a loop pipeline, the overall attractiveness requirements of high-rise buildings are satisfied, and power-free circulation of the working media is achieved by the capillary action of the capillary structure. The whole solar water heater has the advantages that the solar water heat is simple to mount, other power drive working media are not needed, and the daily requirements of people can be satisfied.

Description

technical field [0001] The invention relates to a heat collecting evaporator and a solar water heater, in particular to a steam box heat collecting evaporator and a solar water heater with the heat collecting evaporator. Background technique [0002] Today, when traditional energy sources such as oil, coal, and natural gas are increasingly tense, in order to protect the environment and achieve sustainable development, it has become a trend to develop new energy and renewable resources. Solar energy has become an important new energy due to its advantages of abundant resources, renewable, no need for mining, transportation, and no pollution. At present, solar water heater technology is the most mature technology and the most widely used solar energy utilization technology in solar heat utilization. [0003] Traditional integrated solar water heaters can meet the needs of low-rise buildings. However, the roofs of medium and high-rise buildings, especially high-rise buildings,...

Problems solved by technology

[0003] Traditional integrated solar water heaters can meet the needs of low-rise buildings. However, the roofs of medium and high-rise buildings, especially high-rise buildings, are not suitable for installing traditional solar water heaters. They cannot meet the requirements of integration with medium and high-rise buildings and affect the aesthetics of buildings. Security risks

In order to solve the above problems, people are working hard to study split solar water heaters. The heat collecting evaporator and the water storage tank are connected by pipes, but the water storage tank still needs to be installed outdoors. Internal and external transportation, there are problems such as large heat loss and low solar energy conversion efficiency, and it needs to rely on gravity to provide the power of the system cycle. The power to provide the system cycle needs to consume electric energy, which is not conducive to saving energy
