Solar heater

Abstract

The invention relates to a heating device, in particular to a solar heater which comprises solar pipes. Each solar pipe comprises an outer pipe and an inner pipe, vacuum is formed between each outer pipe and the corresponding inner pipe, the solar pipes are parallel to one another, a blocking and diversion piece is arranged in the inner pipe of each solar pipe and inserted along the radius direction of the inner pipe, a gap is reserved between the tail end of each blocking and diversion piece and the bottom wall of the inner pipe of the corresponding solar pipe, a lateral side, along the height direction of the corresponding inner pipe, of each blocking and diversion piece and the wall of the inner pipe are in interference fit, the top end of each blocking and diversion piece is bent and higher than a pipe orifice of the corresponding inner pipe, a sealed box is arranged on the upper portions of the solar pipes, the solar pipes which are parallel to one another and the sealed box are in closed connection, a gap is formed between the top end of an aluminum piece and the wall of the sealed box, an inlet and an outlet are arranged at the left end and the right end of the sealing box, and a medium circulating device is arranged at the inlet and / or the outlet. The solar heater does not need a water tank and is small in occupied space and convenient to use and mount, and heat of sunlight is fully utilized, so that energy resources are saved.

Description

technical field [0001] The invention relates to a heating device, especially a solar heater. Background technique [0002] Existing solar heaters are generally called "solar water heaters", which use liquid, namely water, as the heat-conducting medium. The working principle is to use solar tubes to absorb the heat of sunlight, and conduct the heat to the water in the tubes to heat the water. , when the water reaches a certain temperature, it can meet the needs of people's daily life, and it can also be used as a heating system in winter to increase the indoor temperature. However, in order to increase its heating temperature and ensure the normal circulation of water flow, a large amount of water generally needs to be used, so solar water heaters usually have a water tank. However, the solar energy equipped with a water tank has a large volume and takes up a lot of space, which brings inconvenience to the installation and use of the solar energy, and increases the manufactu...
