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.
