Solar water heater

Abstract

The invention relates to a plastic inner liner of a water heater, comprising a liner body provided with a cold water inlet and a hot water outlet. The invention is characterized in that the liner body comprises a plurality of parallel horizontal pipes and a plurality of parallel longitudinal pipes; and the horizontal pipes and the longitudinal pipes are positioned on the same plane and are connected with each other by interpenetration. The plastic inner liner of the water heater adopts pipe network type plate structure, has strong pressure bearing capacity, secure structure and good water mobility, can be manufactured by plastic materials, does not produce scale, resists corrosion, occupies less space and is convenient to design and install.

Description

technical field [0001] The invention relates to a solar water heater. Background technique [0002] Ordinary solar water heaters mostly absorb heat through glass heat collecting tubes, and store hot water in drum-shaped water tanks. This water heater produces high water temperature and high thermal efficiency, but it also has the problems of large volume, complex structure and high cost. High prices restrict the popularization of solar water heaters, especially in tropical or subtropical regions with long sunshine hours and high average temperatures. It is acceptable to have a slightly lower thermal efficiency. People are more concerned about reducing production costs, thereby reducing sales prices, in order to benefit solar energy. Popularization of water heaters. Contents of the invention [0003] The object of the present invention is to provide a solar water heater with simple structure, less space occupation and low cost. [0004] To achieve the above object, the p...
