Problems solved by technology

However, if it is used in small heat exchange equipment, such as a small electric water heater for household use, the heat exchange effect is not very ideal because the heat exchange pipeline is too short, especially when it is necessary to control the temperature and water flow, it cannot be controlled arbitrarily. And the energy saving effect is not good
In addition, the electric water heaters in the prior art generally have unsatisfactory heat preservation effects, large heat loss, and no energy storage function and heat-assisting function.

Abstract

The invention provides a phase change energy storage electric water heater, which comprises a water tank and a heat exchange coil and electric heating rods arranged in the water tank. The heat exchange coil is a multilayer horizontal spring coil, and the electric heating rods are arranged in a layering manner corresponding to the multilayer horizontal spring coil. The water tank comprises a shell and a liner, a heat preservation layer and a phase change material energy storage layer are arranged between the shell and the liner sequentially from outside to inside, the heat exchange coil is arranged in the liner, and the liner is filled with a heat aid. The phase change energy storage electric water heater is good in heat exchanging effect, high in heat exchanging speed, slow in water cooling, capable of saving energy and water, capable of realizing heating in a layering manner, and capable of making into water heaters in different sizes and with different usages.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a phase change energy storage electric water heater. Background technique [0002] Heat exchange equipment is widely used in all aspects of industry and life, and heat exchange tubes are the most commonly used components in heat exchange equipment. The heat exchange tubes in the prior art generally adopt serpentine coils, row tubes, or spiral (also called single-layer spring type) coils. When the above-mentioned heat exchange tubes are used in large heat exchange equipment, there is no big problem. However, if it is used in small heat exchange equipment, such as small household electric water heaters, the heat exchange effect is not very ideal because the heat exchange pipeline is too short, especially when it is necessary to control the temperature and water flow, it cannot be controlled at will. And the energy saving effect is not good. In addition, the electric water heaters in t...
