External channel heat collecting evaporator and solar water heater with the heat collecting evaporator

Abstract

The invention provides a heat collection evaporator with an external channel, which comprises a heat insulation casing and a closed shell, wherein a capillary structure layer is arranged in the closed shell; a solar panel is arranged on the upper part of the closed shell; a glass cover board covers the upper part of the solar panel; a plurality of steam collection channels are pressed at the bottom of the solar panel; a plurality of steam collection channels cover the capillary structure layer; the conventional solid steam channel is replaced by the pressed steam collection channels, and a working substance entering the capillary structure layer is evaporated after the solar panel absorbs heat, so that the heat is provided. The invention also provides a solar water heater provided with the heat collection evaporator; the heat collection evaporator is communicated with a water storage tank through a loop pipeline, so that requirements on integral beautification of middle-high buildings are met, meanwhile, unpowered cycle of the working substance is achieved by utilizing the capillary action of the capillary structure, the whole solar water heater is simple to install, and does not need other power to drive the working substance, so that daily requirements of people can be met.

Description

technical field [0001] The invention relates to a heat collecting evaporator and a solar water heater, in particular to a heat collecting evaporator with an external channel 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-...

AI Technical Summary

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
