Solar water box with steady flow big heat-exchange surface porcelain enamel heat-exchanging liner

Abstract

The invention discloses a solar energy water tank with a steady flow large heat-transfer surface enamel heat exchanging liner, comprising medium circulating interfaces (1, 2), a heat exchanger (3) and a liner main body (4). The heat exchanger (3) is long and narrow dolioform structure, a section (5) of which is dolioform. A stiffener (6) which is distributed in an up and down staggered way can be arranged in the heat exchanger (3). With the structure adopted, the long and narrow dolioform heat exchanger reduces the volume occupied in the water tank, enlarges the relative heat exchanging surface area and can ensure the heat exchanging effect. The stiffener which is distributed in the heat exchanger in the up and down staggered way improves the pressure bearing capacity and can control the flowing of water to be stable.

Description

technical field [0001] The invention relates to a solar water tank, in particular to a solar water tank with an enamel heat exchange inner tank with a steady flow and a large heat exchange surface. Background technique [0002] With the popularity of solar water heaters, users have higher and higher requirements for the functions of water heaters. The structure of the solar water tank of the prior art generally includes a shell, water inlet and outlet pipes, a heat exchanger and an inner container. In addition to electric heating, this kind of water tank can also carry out medium circulation through the heat exchanger in the water tank, thereby improving the heat exchange effect of the water tank. However, most of the current heat exchangers are circular. Due to the structure, the volume occupied in the water tank is relatively large, and the relative heat exchange surface area is small, so the heat exchange effect is not satisfactory. In addition, the pressure of the circu...

However, most of the current heat exchangers are circular. Due to the structure, the volume occupied in the water tank is relatively large, and the relative heat exchange surface area is small, so the heat exchange effect is not satisfactory. In addition, the pressure of the circular structure heat exchanger The capacity is not enough, once the heat exchanger is deformed due to pressure, the enamel on its outer surface will peel off, affecting the service life
