Brick tile type solar heat collector
Technical Field
The invention relates to the technical field of photovoltaic equipment, in particular to a tile type solar heat collector.
Background
Solar thermal energy systems collect heat from the sun and utilize it to heat space or water. Solar thermal energy systems include components that collect solar heat, store the heat, and transport the heat to where it is needed.
Solar collectors are components of solar thermal systems that collect solar heat. Typically, they are located on the roof of a house where they are readily visible. There are many different types of solar collectors.
The most common type of solar collector is a glazed flat panel collector. This type of collector comprises a weatherproof and thermally insulated housing or framework that houses a metal absorber plate with an internal tube. Typically, it is 2 to 3 inches thick and resembles a skylight. It is also typically mounted directly on or just above the roof of the house, leaving it exposed to sunlight. The tubes built into the absorber carry a heat transfer fluid that is typically water but may be a different fluid such as propylene glycol. The absorber is located within the collector and is typically black or other dark color in order to absorb as much solar energy as possible. The flat panel collector also includes a transparent or translucent cover over the absorber. The cover is typically a solar safety glass that functions to slow down heat loss and capture solar energy into the collector. Insulation at the bottom of the collector, behind the absorber and at the sides reduces conductive heat loss. Solar energy heats the water in the tube causing it to flow through the system and to be delivered to a water holding tank located within the house.
Another type of solar collector is the evacuated tube solar collector consisting of a row of parallel glass tubes. There are many types of vacuum tubes used in this type of collector, such vacuum tubes sometimes being referred to as "solar tubes" or "heat pipes". The first type of vacuum tube consists of two glass tubes fused together at one end. The inner tube is coated with selective surfaces that absorb solar energy well but inhibit radiant heat loss. The space between the two glass tubes is evacuated or "pumped out" of air to form a vacuum, which eliminates conductive and convective heat losses. The second type of vacuum tube consists of a single glass tube with a flat or curved aluminum plate inside the tube, attached to a copper heat pipe or a water flow pipe. The aluminum plate is typically coated with Tinox or similar selective coating. A third type of vacuum tube uses a glass tube that incorporates a water flow channel into itself. In this type of collector, the solar tube or heat pipe acts as a heat absorber within a larger evacuated glass tube. The evacuated glass tube acts like a thermos bottle to contain the absorbed heat. The heat pipe contains a fluid that evaporates at low temperatures and is resistant to freezing. The water vapor rises in each individual heat pipe or solar tube and heats the carrier fluid in the manifold. The vaporized fluid condenses to a liquid after it has been supplied with its heat and then flows back to the bottom of the heat pipe or solar tube. The vacuum tube collector must be properly angled to allow the ongoing process of evaporation and condensation of the fluid.
Another type of solar collector is an unglazed flat panel collector. This type of collector comprises an absorber incorporating a conduit for a water stream. The absorber can be made from a variety of materials including metal or extruded polypropylene plastic. The water flow conduit captures solar energy to heat the water in the conduit. Because unglazed flat panel collectors are lightweight and formed in different sizes, they are installed in many locations such as on roofs, grills or outhouses.
The existing solar collector is exposed outside, so that dust falls into the solar collector, the dust falling into the solar collector not only influences the light conversion efficiency, but also enables the voltage on the photovoltaic panel to be unstable, and the service life of the photovoltaic panel is shortened.
