Abstract

The invention discloses a vertical pressure-bearing double-cycle all-plastic water tank liner, comprising an end cover and a water tank. An annular groove on the end cover is connected with the water tank to form an annular hole, and the annular hole is communicated with the holes in the water tank wall and is communicated with the outside via a pipe of the annular groove. Multiple holes in the water tank wall are connected in parallel to form a circular channel, the circular channel has a large total cross section, and the circular medium has very low flow resistance, thus laying a foundation for realizing the working state of heating by natural circulation. In the invention, the heat exchange surface is big enough, thus the heat resistance is small, the heat exchange temperature is low, the heat exchange surface is prevented from scaling, and higher heat transfer efficiency can be maintained forever. The liner in the invention is mainly made from a polymer material and has the advantages of long service life, high reliability, simple production process, capability of large-scale industrialized production and wide market prospect, a great quantity of metal raw materials are saved, and the system manufacturing cost is greatly lowered.

Description

Technical field [0001] The invention relates to an inner liner of an insulated water tank, in particular to an inner liner of a vertical pressure-bearing double-circulation all-plastic water tank. Background technique [0002] At present, most of the heat preservation water tanks used for solar water heaters and electric water heaters are made of stainless steel inner tanks. Due to the intergranular corrosion problem in the welds of stainless steel inner tanks, the short service life is an unsolved global problem. Although steel plate enamel inner tanks have been used in recent years at home and abroad However, the processing technology of the enamel liner is high, and air bubbles or pinholes are likely to occur during the production process. At the same time, the enamel is relatively brittle, and vibration and collision are prone to scale explosions. In addition, the enamel will gradually dissolve and peel off in hot water. Technically It is called "boiling water weightless...
