Vertical solar water heater

Abstract

The invention discloses a vertical solar water heater, comprising a water storage tank and a glass tube unit composed of a plurality of communicated glass tube units, each glass tube unit is coated with a heat transfer coating; each glass tube unit comprises an incoming water pipe and an incoming water pipe and an outgoing water pipe; the water storage tank is provided with a cold water pipe and ahot water pipe; the glass tubes are mounted in a square frame in parallel manner; both the top and bottom of the square frame are of open structure; the square frame is obliquely mounted on a support; the water storage tank is mounted below the square frame; a reflecting plate is arranged at each end of the top of the water storage tank; the reflecting face of each reflecting plate faces the glass tube units; the height of the reflecting plates is not less than 1 / 2 of the height of the top end of the glass tube units. The vertical solar water heater has the advantages that it can be ensured that all sides of the glass tubes can receive sunlight, heat production efficiency is high, and effectively utilization rate of solar energy can be increased.

Description

technical field [0001] The invention relates to a solar energy device, in particular to a vertical solar water heater. Background technique [0002] A solar water heater is a device that converts sunlight into heat energy, which can heat water from a lower temperature to a higher temperature to meet the needs of people in daily life. The various solar water heaters that install and use now all are a plurality of vacuum glass tubes arranged in parallel on one side of the horizontally placed water tank. This traditional installation structure can only receive sunlight on one side, and its thermal energy efficiency is low, which is not conducive to the effective use of solar energy. [0003] CN105698407A discloses a vertical solar water heater, which is distributed with heat-absorbing glass tubes arranged around the periphery of a vertical water tank. Through the above-mentioned settings, the glass tubes can receive sunlight at any angle. In order to improve the thermal effic...

[0003] CN105698407A discloses a vertical solar water heater, which is distributed with heat-absorbing glass tubes arranged around the periphery of a vertical water tank. Through the above-mentioned settings, the glass tubes can receive sunlight at any angle. In order to improve the thermal efficiency of solar water heaters, but this kind of setting has the same problem as other existing water heaters: only a part of the surface of the glass tube can receive sunlight, and there is always a backlight side of the glass tube. Because one side of the glass tube cannot receive sunlight, it cannot heat the cold water well, so that the temperature of the hot water in the glass tube is uneven, which affects the total temperature of the hot water in the glass tube. The most important thing is that this phenomenon is still not good. Conducive to the effective use of solar energy, causing waste of solar energy
