Solar thermal collector and heating system applying same

Abstract

The invention relates to a solar thermal collector and a heating system applying the thermal collector. The solar thermal collector can be used for drying clothes or heating water and comprises a solar thermal collecting tube, a unifying device and a heating system; wherein the solar thermal collecting tube is a duplicature vacuum tube, the two ends of the solar thermal collecting tube are all connected with the unifying device and are communicated with a semi-ring channel, thus forming a solar thermal collector; the heating system can be a clothes-drying system composed of a clothes-drying case, a condenser, a hanger, a fan and an air pipe and also can be a water heating system composed of a thermal storage tank, a steam outlet, a heating coil tube, a water tube, a tap and a superconductive liquid tube. The invention overcomes the defects of the existing solar thermal collector and provides a solar thermal collector capable of drying cloths or heating water as well as a heating system applying the solar thermal collector, manufacturing process is simple, starting is fast, cost is lower, use is reliable, thermal absorption area is wide, thermal utilization factor is high, and corrosion resistance can be achieved.

Description

1. Technical field [0001] The invention relates to a solar heat collector and a heat supply system using the heat collector, in particular to a solar heat collector capable of drying clothes or heating water supply and a heat supply system using the heat collector. 2. Background technology [0002] The use of solar energy is of great significance for taking the road of sustainable development, protecting the ecological environment on which human beings depend, and solving the energy supply problem of those without electricity. The efficient and pollution-free use of solar energy is even more important for saving energy and protecting the natural environment. It is meaningful. In the solar thermal utilization system, the key is how to efficiently collect sunlight and convert it into heat energy. At present, heat utilization is a comprehensive project in solar energy utilization technology. [0003] At present, solar collector tubes are generally open at one end and closed a...

Problems solved by technology

The natural circulation hot water system composed of them often relies on the density difference generated by the difference in water temperature between the collector and the water storage tank for temperature difference circulation (thermosiphon circulation), and its water circulation speed is high, and the heat utilization rate is not high.

At present, the inner and outer tubes and joints of vacuum solar collector tubes commonly used are rigid connections of glass inner and outer tubes. The surface of the inner tube is coated to improve the absorption rate of solar radiation. Like a very slender thermos bottle, this kind of heat collecting tube needs to be made of heat-resistant glass with a small thermal expansion coefficient, and the process is complicated and the cost is high. During the use process, due to hail, flying stones and other reasons, Once the outer tube breaks, the whole tube will be scrapped, and the heat absorption area is small, and the heat utilization rate is not high
