Description

Solar water heater with protection function

Technical Field

The utility model relates to a solar energy field specifically is a solar water heater with safeguard function.

Background

The solar water heater is a heating device for converting solar energy into heat energy, and heats water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. The solar water heater is divided into a vacuum tube type solar water heater and a flat plate type solar water heater according to the structural form, mainly uses the vacuum tube type solar water heater as a main part, and occupies 95 percent of domestic market share. The vacuum tube type domestic solar water heater is composed of heat collecting tube, water storage tank and support, and can convert solar energy into heat energy, and mainly depends on the vacuum heat collecting tube, and the vacuum heat collecting tube can utilize the principle of that hot water floats upwards and cold water sinks to make water produce microcirculation to obtain the required hot water.

As the solar water heater is generally arranged in an open-air area capable of directly irradiating the sun, and a plurality of areas are just hail-prone areas, once hail occurs, the vacuum tube on the surface of the solar panel is directly impacted, and the solar panel is easy to damage; the solar water heater has high efficiency, the water temperature can reach the boiling point in less than two days under the condition of fine days in summer, if water is not used for a long time, such as during business trips and travels, the aging of a sealing ring can be promoted, the aging and the atrophy of polyurethane can be accelerated, sometimes, the air exhaust is not smooth, the water tank can be expanded and damaged due to too high pressure, water scale can be formed, and the service life of the water tank can be shortened. Therefore, when the sunlight is strong, a covering object is placed on the vacuum tube to block the sunlight.

The patent with the application number of CN200620020657.5 and the publication number of 2007.03.14 discloses a covered hail-proof solar water heater, which is characterized in that: the hail-suppression water heater is composed of a water bucket, an upper frame, a hail-suppression cover plate, a water heater support, a hail-suppression cover plate support, a photothermal conversion glass tube, screws and a bottom frame. Hail-suppression cover plate supports are installed on the two sides of the water heater support, hail-suppression cover plates are installed on the hail-suppression cover plate supports, the upper ends of the hail-suppression cover plates are welded to the upper frame, the lower ends of the hail-suppression cover plates are embedded to the bottom frame, photo-thermal conversion glass tubes are installed below the hail-suppression cover plates, and buckets are installed at the top of the water heater support. Although this product simple structure has set up protection device on solar water heater's shell, the water heater can not damage light and heat conversion glass pipe because of meetting the wind and raining, hail, has increased solar water heater's life, but the hail-proof apron can't remove, and in use has inconveniently, needs to improve this scheme.
