Abstract

The invention discloses a multi-spiral-pipe type full-plastic pressure-bearing dual cycle inner container, which mainly comprises an inner container and a heat exchanger, wherein the heat exchanger is formed into a circulation channel by a plurality of spiral tubes in a parallel state; and the total section value of the circulation channel is extremely large and flow resistance of a circulation medium is rather low, so the circulation channel can work in a natural circulation heating working state. The heat exchange area of the multi-spiral-pipe type full-plastic pressure-bearing dual cycle inner container is large enough, so the heat resistance and the heat exchange temperature are low; furthermore, a heat exchange surface is difficult to scale and higher heat exchange efficiency can be always kept. The multi-spiral-pipe type full-plastic pressure-bearing dual cycle inner container is mainly made from polymer, modified polymer or enhanced polymer, so a large quantity of metal raw materials can be saved and the manufacturing cost of a system can be reduced greatly; furthermore, the multi-spiral-pipe type full-plastic pressure-bearing dual cycle inner container has long service life, high reliability and a wide marketing prospect and can be industrially produced on a large scale; and the production technology for the multi-spiral-pipe type full-plastic pressure-bearing dual cycle inner container is simple.

Description

Technical field [0001] The invention relates to a water tank liner, in particular to a multi-spiral tube type all-plastic pressurized double-circulation 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...
