Vacuum instant-heating type micro-heat tube solar water heater

Abstract

The invention discloses a vacuum instant-heating type micro-heat tube solar water heater, and relates to the field of solar energy utilization. The vacuum instant type micro-heat tube solar water heater integrates the advantages of a micro-heat tube type heat collector and a vacuum tube type heat collector, the heat collection efficiency is high, the heat preservation performance is good, and thephoto-thermal conversion efficiency can be greatly improved; the vacuum instant-heating type micro-heat tube solar water heater comprises surface coating micro-heat tubes, coating vacuum tubes, a heatexchanger and an energy storage heat exchange water tank, wherein the surface coating micro-heat tubes are inserted into the coating vacuum tubes, the surface coating micro-heat tubes penetrate through the upper end and the lower end of the micro-heat tubes, solar spectrum selective coatings are arranged at the parts, outside the energy storage heat exchange water tank, of the lower ends of the micro-heat tubes, the middles of the micro-heat tubes are connected with the heat exchanger, the connection parts are coated with heat conduction glue and fixed in a buckled mode, the upper ends of themicro-heat tubes are connected with heat transfer metal pipes, and the connection parts are coated with the heat conduction glue and fixed in a buckled mode; the energy storage heat exchange water tank is composed of a heat preservation layer and a shell, the energy storage heat exchange water tank is provided with an opening, the surface coating micro-heat tubes are inserted into the water tank,the heat exchanger and the heat transfer metal pipes are fixed inside the water tank through a buckle, and the heat resistance of the heat transfer metal pipes is smaller than that of heat exchangerfins.

Description

technical field

[0001] The invention mainly relates to the field of solar energy utilization, in particular to a vacuum instant heating micro heat pipe solar water heater. Background technique

[0002] With the rapid development of the world economy, traditional fossil fuels are gradually being exhausted. The energy crisis and environmental pollution make people accelerate the exploration, development and utilization of renewable energy. With unique advantages such as inexhaustible, clean and pollution-free, solar energy has become the preferred energy source among many renewable energy sources.

[0003] As an important field of solar energy utilization, solar collector is a device that converts the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. At present, the solar collectors commonly used in the market are divided into flat-plate collec...
