Active heat pipe flat solar water heater

Abstract

The invention discloses an active heat pipe flat solar water heater which comprises a hot water tank, a condensation heating coil arranged in the hot water tank, a liquid storage tank, a working medium pump, a bearing-type flat heat collector and a gas-liquid separator, wherein an outlet of the liquid storage tank is connected with an inlet of the working medium pump; an outlet of the working medium pump is connected with an inlet of the bearing-type flat heat collector; an outlet of the bearing-type flat heat collector is connected with an inlet of the gas-liquid separator; the gas-liquid separator comprises a first outlet and a second outlet; the first outlet is a gas outlet, and the second outlet is a liquid outlet; the gas outlet is connected with an inlet of the condensation heating coil; and the liquid outlet and an outlet of the condensation heating coil are respectively connected with an inlet of the liquid storage tank. The working medium pump is adopted to provide transmission power, the bearing-type flat heat collector is adopted, and the low-temperature environment-friendly working medium is used as the heat carrying medium when in use, thereby solving the problem of limited power in the heat pipe solar water heater, enhancing the solar heat collection efficiency and widening the applicability of the solar water heater.

Description

technical field [0001] The invention relates to a solar water heater, in particular to an active heat pipe flat plate solar water heater. Background technique [0002] Solar energy is an inexhaustible green energy source. As a representative of direct and effective utilization of solar energy, solar water heating system is widely used all over the world. At present, solar water heating systems on the market are mainly divided into all-glass vacuum tube solar water heaters, flat plate solar water heaters and heat pipe solar water heaters. [0003] The all-glass vacuum tube solar water heater has become the most popular solar water heating system in China due to its simple structure, low cost, and mature production technology. Its main structure is composed of inner and outer glass tubes, the vacuum treatment is carried out between the inner and outer glass tubes, and the vacuum side of the inner tube is coated with selective absorption coating. When working, the inner pipe...

Problems solved by technology

The disadvantages of flat-panel solar water heaters are: low heat collection temperature, easy to freeze and crack in low temperature environments, and poor adaptability at low temperatures

However, this kind of water heater only relies on natural circulation, with limited power, limited condensing end area, and narrow application range.
