Abstract

The invention discloses a solar water heater which comprises a solar heat collector and a heat storage water tank. A condenser is arranged in the heat storage water tank and communicated with the solar heat collector through a pipe, a heat collecting panel is arranged on the solar heat collector, a plurality of backflow branch pipes are arranged on the heat collecting panel at intervals, the upper ends of the backflow branch pipes are communicated through an upper collecting pipe, the lower ends of the backflow branch pipes are communicated through a lower collecting pipe, an air inlet of the condenser is communicated with the upper collecting pipe through a connecting pipe, a backflow opening of the condenser is communicated with the lower collecting pipe through a backflow pipe, an air discharging and liquid charging valve is arranged on the connecting pipe, and a heat preservation layer is arranged on the outer wall of the heat storage water tank. According to the solar water heater, phase change heat transferring is adopted, the heat transferring efficiency is greatly improved, and the aim that the solar water heater is resistant to freezing in winter is effectively achieved.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater adopting liquid medium phase change heat transfer. Background technique [0002] A solar water heater is a solar energy utilization device that uses solar energy as an energy source to heat water or a heat transfer medium. [0003] The traditional flat-panel solar water heater is composed of a hot water storage tank, a heat collector, connecting pipes and supports. The water inlet and outlet of the hot water storage tank are respectively connected with the water outlet and the water inlet of the heat collector through connecting pipes to form a circulation channel. The temperature of the collector rises after being irradiated by sunlight, and the water is heated after flowing through the collector. The water in the hot water storage tank flows through the collector through the connecting pipes and circulates continuously, and the water in the hot water storage tank i...
