Problems solved by technology

This kind of 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

Embodiment Construction

[0018] Such as Figure 1-4 As shown, a solar water heater according to the present invention includes a shell 1 and a heat absorbing tank 2 fixedly installed in the shell 1 , and the heat absorbing tank 2 is provided with a water inlet 3 and a water outlet 4 . A thermal insulation layer 5 is filled between the bottom of the heat absorption tank 2 and the shell 1 , and a transparent thermal insulation board 6 is covered on the top of the heat absorption tank 2 . In order to reduce the cost, the heat-absorbing tank 2 and the shell 1 are made of plastic materials. Of course, in order to take into account the thermal efficiency at the same time, the material of the heat-absorbing tank 2 should be a plastic material with good heat-absorbing performance. The transparent heat preservation board 6 can adopt the glass plate or the interlayer, the hollow glass plate with strong light transmittance and heat preservation effect. This can not only ensure that light is irradiated on the he...

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...
