Tubular heat-collection evaporator and solar water heater with same

Abstract

The invention provides a tubular heat-collection evaporator. The tubular heat-collection evaporator comprises a thermal insulation case, a solar heat-collection plate, multiple evaporation tubes and a glass cover plate. The evaporation tubes are arranged between the glass cover plate and the solar heat-collection plate, capillary structure layers are laid at the bottoms inside the evaporation tubes, steam flowing channels are formed in the upper layers inside the evaporation tubes, and a steam pipeline and a working medium returning pipeline are arranged on the two sides of the thermal insulation case respectively. The solar heat-collection plate absorbs heat, then working media inside the evaporation tubes are evaporated, and therefore the heat is provided. The invention further provides a solar water heater with the heat-collection evaporator. The heat-collection evaporator is communicated with a water storage tank through a loop pipeline so that the requirement for overall attractiveness of mid-rise and high-rise buildings can be met; meanwhile, under the capillary action of the capillary structures, the working media circulate in a non-power mode, and the whole solar water heater is easy to install and capable of meeting daily requirements of people without other power for driving the working media.

Description

technical field [0001] The invention relates to a heat collecting evaporator and a solar water heater, in particular to a tube type 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
