Self-adaptive heating device of solar water tank

Abstract

The invention discloses an self-adaptive heating device of a solar water tank. The self-adaptive heating device comprises a box body, the interior of the box body is divided into a cold water cavity,a hot water cavity, a mounting cavity and a heating cavity, a three-way pipe is arranged in the mounting cavity, the top end of the three-way pipe communicates with the cold water cavity, the three-way pipe communicates with the hot water cavity through a first pipeline, the three-way pipe communicates with the heating cavity through a second pipeline, and the hot water cavity communicateds with the heating cavity through a third pipeline; the bottom of the hot water cavity communicates with a fifth pipeline, the bottom of the heating cavity communicates with a sixth pipeline, and each pipeline is provided with an electromagnetic valve; and a first electric heating plate and a second electric heating plate are mounted at the bottom of the heating cavity, a first coil pipe and a second coilpipe which are used for transferring heat are arranged on the box body, a heat collecting plate is arranged on the outer side of the first coil pipe, and a first photovoltaic panel is arranged on theouter side of the heat collecting plate. According to the self-adaptive heating device, solar energy and heat energy can be fully utilized for heating, the coordination relation between cold water and hot water in the water tank can be adjusted in time according to the actual use condition, self-adaptive adjustment is achieved, and the use comfort is improved.

Description

technical field [0001] The invention relates to the technical field of solar water tanks, in particular to an adaptive heating device for solar water tanks. Background technique [0002] With the utilization of solar energy, solar heating water tanks can be seen everywhere in cities and rural areas. Solar heating water tanks use solar energy to heat cold water, reducing the power consumed in the heating process of traditional electric water heaters; but this kind of traditional solar water tanks can only pass through Photovoltaic power generation produces hot water, and after photovoltaic cells absorb sunlight, less than 20% of it is converted into electrical energy, and the rest is converted into heat. The heat cannot be utilized and is lost in the air, resulting in a large waste and unable to provide more sufficient heat. use; and the coordination between the internal cold water and hot water cannot be better self-adapted and adjusted to facilitate practical use.
