Empty-shining-resistant solar energy heat collection pipe

Abstract

The invention discloses an energy-shining-resistant solar energy heat collection pipe. The energy-shining-resistant solar energy heat collection pipe comprises a pipe body; a groove is formed in the lower end of the pipe body; a sliding block is slidably connected into the groove; the outer part of the pipe body is further coaxially sleeved with a rotary sleeve which is manufactured by adopting atransparent material; the rotary sleeve can freely rotate around the axis of the rotary sleeve; the lower end of the sliding block is fixedly connected to the inner bottom of the rotary sleeve througha memory metal sheet; besides, the memory metal sheet coincides with the axis of the rotary sleeve; the memory metal sheet is twisted into a twisted shape at room temperature, and is of a sheet shapewhen the temperature exceeds the transformation temperature; and the end, which is located in the groove, of the sliding block is provided with a heat conductive sheet through welding. The energy-shining-resistant solar energy heat collection pipe is exquisite in structure and low in production cost; electric monitoring equipment is not needed; cost and manufacturing difficulty are effectively lowered; meanwhile, functions of self-protection, empty-shining-resistance and the like of a water heater are realized more accurately and scientifically; and the energy-shining-resistant solar energy heat collection pipe has obvious advantages.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to an anti-air solar heat collection tube. Background technique [0002] A water heater is a tool that provides hot water for a limited range. After years of development, water heaters are divided into the following categories: storage electric water heaters, instant electric water heaters, instant electric water heaters, gas water heaters, solar electric water heaters and air Source water heaters; Among them, solar water heaters are favored by users for their advantages of environmental protection, energy saving, and convenience. [0003] The traditional solar water heater heats the water body through the heating tube, uses the thermosiphon effect to heat the water body and sends it to the water storage tank; in daily use, the water storage tank needs to be replenished regularly to meet the daily use; but when the user forgets to fetch water, the heating tube will In a hollow...

Problems solved by technology

[0003] The traditional solar water heater heats the water body through the heating tube, uses the thermosiphon effect to heat the water body and sends it to the water storage tank; in daily use, the water storage tank needs to be replenished regularly to meet the daily use; but when the user forgets to fetch water, the heating tube will In a hollow state, as the light continues and strengthens, the heating tube will continue to heat up. Since there is no heat absorption by the water body, the heating tube is prone to aging and damage due to air drying, and the coating on the heating tube will also fall off, which will greatly shorten the temperature. The service life of the water heater may even cause safety accidents
