Embodiment Construction

[0021] The accompanying drawings describe the structural form of an inner tank of a pressurized double-circulation metal heat exchanger. The liner 7 is made of a polymer material, or a modified polymer material, or a reinforced polymer material, or a composite polymer material; there is a reinforcement layer 8 in the wall of the liner 7, and a plurality of circular trusses or Pyramid-shaped holes 9; the reinforcing layer is tubular, or spiral, or annular, or reticular, or fiber-dispersed structure; the reinforcing layer 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; reinforced layer or outside the inner tank wall; hot water pipe 11 communicates with the upper part of the inner cavity of the inner tank through hot water pipe interface 6; cold water pipe interface 17 communicates with the lower part of the inner cavity of the inner ta...

Abstract

The invention relates to a pressure-bearing dual-circulation metal heat exchanger liner, which mainly comprises a liner and a heat exchanger. The flowing resistance of a circulating medium of the heat exchanger of the pressure-bearing dual-circulation metal heat exchanger liner is low, thus a naturally-circulating heating working state can be adopted. By adopting the wing bucket-shaped heat exchanger of the pressure-bearing dual-circulation metal heat exchanger liner, the volume of an inner cavity of the heat exchanger can be reduced, higher heat exchange efficiency is obtained, and heat of the system can be increased. The pressure-bearing dual-circulation metal heat exchanger liner is manly made of a high polymer material, a modified high polymer material and an enhanced high polymer material, thus a large quantity of metal raw materials can be saved, manufacture cost of the system is greatly reduced; and the pressure-bearing dual-circulation metal heat exchanger liner has the advantages of long service life, high reliability, simple production process, capability of massive industrialized production, and wide market prospect.

Description

Technical field [0001] The invention relates to a water tank liner, in particular to a pressurized double-circulation metal heat exchanger liner. 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" phenomenon, which makes it difficult to guara...
