Efficient solar heat collector

Abstract

The invention discloses an efficient solar heat collector. The efficient solar heat collector comprises a heat collection pipe cluster, a reflection plate and a controller. The heat collection pipe cluster comprises a plurality of heat collection pipes arranged side by side. A sunshade pipe is arranged outside each heat collection pipe. Each heat collection pipe is formed by splicing a plurality of first arc plates concentric with the corresponding heat collection pipe. One sides of the first arc plates are hinged to the heat collection pipes through fasteners so that the first arc plates can rotate relative to the heat collection plates. The reflection plate is formed by sequentially splicing a plurality of second arc plates arranged side by side and connecting plates, and the upper portion of each connecting plate is in sliding connection with a corresponding sliding plate. The controller is arranged to control the first arc plates to rotate and control the sliding plates to slide on the connecting plates. According to the efficient solar heat collector, solar energy can be converted into heat energy and can also be converted into electric energy to be stored, and the utilization rate of solar energy is increased. The function of shielding the heat collecting pipes and the reflection base plate is achieved, and the service life of the solar water heater is prolonged.

Description

technical field [0001] The invention relates to the field of solar heat collection, in particular to a high-efficiency solar heat collector. Background technique [0002] The use of solar energy is mainly divided into two types, photothermal and photovoltaic, among which solar water heaters are typical of photothermal conversion and utilization. The heat collector of a solar water heater is usually composed of a heat collecting tube and a reflective substrate. The heat collecting tube is provided with a black or dark heat absorbing layer, which absorbs the heat of sunlight and is used to heat the water in the heat collecting tube. The reflective substrate is located under the heat collecting tubes, and reflects the sunlight from the space between the heat collecting tubes back to the heat absorbing layer to improve the heat collecting efficiency. [0003] However, in existing solar heat collectors, its heat collecting tubes, reflective substrates and other components are al...

Problems solved by technology

[0003] However, in existing solar heat collectors, its heat collecting tubes, reflective substrates and other components are always exposed, even when they are not required to work, the heat absorbing layer in the heat collecting tubes and the reflective substrate under the heat collecting tubes are always in working condition. , There is work loss, which reduces the service life

Furthermore, the function of the solar heat collector in the prior art is relatively single, and can only realize light-to-heat conversion, that is, it only has the function of using solar energy to heat water instantly

In this way, when the solar collector does not need to heat the water, the solar energy it collects cannot be used elsewhere, or it can only repeatedly heat the water in the collector pipe meaninglessly, resulting in energy waste
