Embodiment Construction

[0021] The accompanying drawings describe the structural form of an all-plastic pressurized double-circulation spiral tube split solar water heater. The reinforcing layer in the inner tank wall is a spiral, or tubular, or mesh, or fiber dispersed structure; the reinforcing layer in the inner tank wall is made of metal material, or glass fiber, or carbon fiber, or chemical fiber, or steel fiber , or ceramic fiber material, or natural fiber material, or plant fiber, or fiber composite material; the reinforcing layer in the inner tank wall can also be outside the inner tank wall; The spiral network reinforced layer 10 and all pipe joints on the inner tank wall together constitute the inner tank; the thermal insulation layer 28 fixes the inner tank in the middle of the water tank shell 27; the inner tank adopts polymer materials, or modified polymer materials, or reinforced high polymer materials Made of molecular materials or composite polymer materials; inner tank wall 8, inner ...

Abstract

The invention discloses a full-plastic pressure-bearing dual cycle spiral tube type split solar water heater, which mainly comprises a heat preservation water tank, a heat exchanger and a heat collector, 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 natural circulation heating can be realized. The heat exchange area of the full-plastic pressure-bearing dual cycle spiral tube type split solar water heater 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. By a curved-surface shell-type light transmitting plate of the full-plastic pressure-bearing dual cycle spiral tube type split solar water heater, the solar heat collector in a horizontally arranged state or a vertically arranged state has a higher daylighting rate. The split solar water heater 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 split solar water heater 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 split solar water heater is simple.

Description

Technical field [0001] The invention relates to a solar heat utilization device, in particular to an all-plastic pressure-bearing double-circulation spiral tube split solar water heater. 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" phen...
