Abstract

The invention provides a pressure-bearing dual-cycle water tank liner, which is composed of an end cover, a liner pipe and a heat exchanger. Two ends of multiple heat exchange tubes of the heat exchanger are communicated with two hollow spheres, and each hollow sphere is provided with an exhaust pipe and a circulating pipe which are communicated with the outside of the liner. In the invention, the heat exchanger is made from a high polymer material, and as the expansion and shrinkage coefficient of the high polymer material greatly differs from that of scale, scale is incapable of attaching on the heat exchange tubes and heat exchange spheres forever in a cold heat frequent alternation environment, thus higher heat transfer efficiency can be maintained by the heat exchanger. The multiple heat exchange tubes of the heat exchanger in the invention have big area surface, thus having small heat resistance, low heat exchange temperature, high heat exchange efficiency and small heat loss. In the invention, the liner is mainly made from a high polymer material and has the advantages of long service life, high reliability, simple production process, capability of large-scale industrialized production and wide market prospect, a large quantity of metal raw materials can be saved, and the system production cost can be greatly reduced.

Description

Technical field [0001] The invention relates to an inner liner of an insulated water tank, in particular to an inner liner of a pressure-bearing double-circulation water tank. Background technique [0002] At present, most of the thermal insulation water tanks for solar water heaters and electric water heaters are made of stainless steel inner tank, or steel plate enamel inner tank. It has the disadvantages of large circulation resistance and high cost, and some people make the above two inner tanks into a large inner tank with a small inner tank structure, and replace the traditional spiral tube heat exchanger with a sandwich structure between the two inner tanks. It solves the problem of high circulation resistance, but the disadvantages of high cost and complicated process are more prominent. Moreover, compared with the spiral tube heat exchanger, this sandwich structure turns the internal heating of the spiral tube heat exchanger into the one between two inner tanks. Th...
