Composite plastic film water cavity type solar flat-board heat collector

Abstract

The invention discloses a composite plastic film water jacket solar panel heat collector. A water jacket component is arranged between a sunlight plate and an insulating course, wherein, the water jacket component consists of a double-layer composite plastic film which is vertically provided with a plurality of intensified scalding sticking lines to ensure that the double-layer composite plastic film form a plurality of vertical water jackets, the upper ends of the water jackets are communicated one another and are communicated to water outlets, the lower ends of the water jackets are communicated one another and are communicated to water inlets. The outer layer of the double-layer composite plastic film is an ultravioresistant black non-luminous plastic film; the inner layer of the double-layer composite plastic film is an edible plastic film. The plastic material has low cost and simple production technique and is easy to reduce the defective rate; the hot water inside the plastic material water jacket is not easy to form scale, the service life is up to ten years; when the heat collector is used in the winter, the water jacket is not easy to frost crack because the plastic film is elastic, thereby bringing convenience to a user; the whole is lighter.

Description

Composite plastic film water cavity solar flat plate collector technical field The invention relates to a solar flat plate heat collector, in particular to a composite plastic film water cavity type solar flat plate heat collector. Background technique In the prior art, the water cavity of the solar flat plate heat collector is mostly made of metal materials, such as copper material, aluminum material, etc. The water cavity of the solar flat plate heat collector with such a structure has many disadvantages: 1. The cost of metal materials is high; The production process is complicated, and defective products are prone to occur; 2. The service life is short, and the scale generated in the water cavity of the metal material is difficult to clean and reduces the heat conduction efficiency when the collector is used for a long time; 3. When used in winter, the water cavity of the metal material is easy to Frost cracking phenomenon occurs, which brings a lot of inconvenience to ...
