A water heating apparatus unified with solar heat collector using vaccum pipe

Abstract

A solar heat boiler integrated into a solar collector using a vacuum pipe comprises a heat storage tank, a vacuum pipe, a water supply pipe, one or more heat pipes, a heat exchange pipe and a water outlet pipe. The heat storage tank holds the heat medium in a space. The vacuum pip is communicated with the space of the heat storage tank and holds the heat medium. The water supply pipe passes through the space of the heat storage tank and the water flows into the water supply pipe from outside. The heat pipes are connected with one end of the water supply pipe. After the water incoming through the water supply pipe flows into the vacuum pipe and then is first-heated, one or more heat pipes discharge the water to the outside of the vacuum pipe for forming a loop. The heat exchange pipe passes through the accommodation space of the heat storage tank. The heat exchange pipe secondly heats the water discharged from the vacuum pipe. One end of the heat exchange pipe is connected with the other end of the heat pipe. One end of the water outlet pipe is connected with the other end of the heat exchange pipe for supplying the hot water as a target object.

Description

technical field [0001] The invention relates to a solar water heater integrated with a solar heat collector using a vacuum tube, in particular to a double vacuum tube type solar heat collector and a heat storage tank that are integrated into one body, without additional pipes connecting the heat collector and the heat storage tank. A device that sends water supplied as an object directly to a collector for heating. Background technique [0002] The solar energy application system is a technology that utilizes the fluctuating nature and photothermal properties of the sun's rays, absorbs, stores, and converts solar energy to the cooling and heating facilities of buildings and the technology of hot water supply. It is roughly divided into heat collection, heat storage, and application. . [0003] The heat collector is a device that absorbs the sun's radiant energy and transforms it into renewable thermal energy, which plays an important role. Usually, solar collectors have con...

Problems solved by technology

[0006] The general solar collector used in this kind of solar hot water supply system is not only cheap but also the thermal medium can circulate naturally. It is a collector with the highest efficiency, but the temperature of the heat absorbed by the thermal medium is relatively low, which is 80 ℃ below, so the use is limited

[0007] Existing evacuated tube solar collectors, such as figure 2 As shown, a heat conduction plate and a U-shaped heating pipe (220) are arranged in the vacuum glass tube (210) sealed at the bottom, and the heat temperature absorbed by the heat medium is 80°C to 200°C, which is higher than
