Embodiment Construction

[0013] As shown in the figure, a medium tank 2 is built in the water tank 1. The medium tank 2 and the medium source are connected to the expansion tank 3 through the medium pipeline, and the expansion tank 3 is left with an air outlet 8; the upper end of the medium tank 2 is connected to the high temperature The medium pipe 4 is connected to a low-temperature medium pipe 5 at the lower end of the medium box 2, and the high-temperature medium pipe 4 and the low-temperature medium pipe 5 are respectively connected to the heat collector 6 to form a loop.

[0014] The heat collector 6 is a heat collector with a built-in U-shaped metal tube 7, and the specific connection mode of the high temperature medium tube 4 and the low temperature medium tube 5 is: the high temperature medium tube 4 and the low temperature medium tube 5 are respectively connected to the heat collecting tube Both ends of the U-shaped metal pipe 7 are connected to form a sealed medium circuit. This structure not o...

Abstract

The invention provides a medium device used for a solar water heater, comprising a medium box and a heat collector which are communicated with each other; wherein, the medium box is internally arranged in the water tank; the medium inlet is connected with an expansion tank; the heat collecting pipe is a 'U'-shaped heat collecting pipe; and the water tank is communicated with the metal pipeline of the U-shaped heat collecting pipe by a pipeline. The medium device utilizes the characteristic that the medium runs without water and is impossible to generate scale and can keep high heat efficiency permanently; the medium inlet is provided with the expansion tank; and during the natural circulation, if tap water stops for a long time, the expansion tank can realize storing energy, prevent the loss of the medium which is arranged under the high temperature for a long time and ensure the sufficient utilization of the medium. The medium device used for the solar water heater can achieve the self-circulation of the medium and eliminate the leakage phenomenon of the medium.

Description

Technical field [0001] The invention relates to a solar water heater, in particular to a media device of a solar water heater capable of realizing medium self-circulation and eliminating medium leakage. Background technique [0002] At present, the solar water heaters on the market are generally vacuum tube solar water heaters, which use vacuum tubes to collect heat and send hot water to the heat preservation water tank through microcirculation. After long-term use, there will be the possibility of scale formation, and high thermal efficiency cannot be maintained for a long time. At the same time, pipelines exposed outdoors are prone to burst and freeze blockage as the use time increases. Summary of the invention [0003] The main task of the present invention is to provide a medium device of a solar water heater, specifically a medium device of a solar water heater that can realize self-circulation of the medium and eliminate the phenomenon of medium leakage. [0004] In order ...
