Embodiment Construction

[0022] Below in conjunction with accompanying drawing, through embodiment, the present invention will be further described: water tank liner comprises end cover, liner pipe and heat exchanger. The liner of the pressure-bearing double-circulation double-tube water tank is made of polymer materials, or modified polymer materials, or reinforced polymer materials, or composite polymer materials; the material for the end cap and the reinforcement layer in the inner wall of the water tank is metal material , or glass fiber, or carbon fiber, or chemical fiber, or steel fiber, or ceramic fiber, or natural fiber, or plant fiber, or fiber composite material. The end cover 2 has a cold water inlet pipe 1, a water retaining plate 3, a convection hole 16, an electric heater insertion pipe 17, a heat exchanger insertion pipe 19, and a reinforcement layer 4; the end cover 2, the cold water inlet pipe 1, and the electric heater insertion Pipe 17, heat exchanger insertion pipe 19, and reinforc...

Abstract

The invention provides a pressure-bearing dual-cycle double-barrelled water tank liner, which is composed of an end cover, a liner pipe and an auxiliary electric heater. Two ends of multiple heat exchange tubes of a 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 frequent cold heat exchange environment, thus higher heat transfer efficiency of the heat exchanger can be maintained. 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 transfer efficiency and small heat loss. In the invention, the liner is mainly made from the high polymer material and has the advantages of long service life, high reliability, simple production process, capability of realizing 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 tank of an insulated water tank, in particular to an inner tank of a pressure-bearing double-circulation double-tube 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 ...
