Abstract

The invention discloses a full-plastic plate pressure-bearing double-loop water tank liner. The full-plastic plate pressure-bearing double-loop water tank liner consists of an end cover and a water tank, wherein an annular groove on the end cover is connected with the water tank to form an annular hole; the annular hole is communicated with holes in the wall of the water tank; the annular hole is communicated with the external through a tube on the annular groove; a plurality of holes in the wall of the water tank are connected in parallel to form a circulation channel; the total cross section of the circular channel is very large; and the flow resistance of a circular medium is very low, which paves a way for a working condition of naturally circular heating. The plastic plate pressure-bearing double-loop water tank liner has an enough heat exchanger area, so that thermal resistance is low and a heat exchange temperature is low; a heat exchange surface does not scale; and higher heat exchange efficiency can be maintained forever. The liner of the invention is mainly made of a high molecular material, can save a large number of metal raw materials, greatly reduces the manufacturing cost of a system, is long in service life, high in reliability and simple in production process, is suitable for large-scale industrial production and has a wide market prospect.

Description

Technical field [0001] The invention relates to a water tank liner, in particular to an all-plastic plate pressure-bearing double-circulation water tank liner. 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 weightlessness" phenomenon, which makes it diff...
