Energy accumulation and heat exchange device and water heater comprising same

Abstract

The invention discloses an energy accumulation and heat exchange device. The energy accumulation and heat exchange device comprises a shell body, a heat preservation separation layer, a heat exchange pipe and a heating part, wherein the heat preservation separation layer is fitted on the inner side of the shell body; the heat exchange pipe and the heating part are arranged in the heat preservation separation layer respectively; the energy accumulation and heat exchange device further comprises an energy accumulation material and a plurality of common fins, wherein the energy accumulation material is filled into the heat preservation separation layer and is used for storing heat of the heating part; a water inlet is connected with one end part of the heat exchange pipe and a water outlet is connected with the other end part of the heat exchange pipe; and all the common fins are immersed into the energy accumulation material and are used for connecting the heat exchange pipe and the heating part. The invention further discloses a water heater comprising the energy accumulation and heat exchange device. The energy accumulation and heat exchange device and the water heater, provided by the invention, are simple in structure, great in energy accumulation amount, high in heat exchange efficiency and easy to produce in a large batch.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an energy storage heat exchange device for phase change energy storage, a water heater and energy storage water heater technology. Background technique [0002] At present, water heaters used in households and industries can be divided into electric heating, gas-fired water heaters and solar water heaters. Among them, electric heating water heaters are the mainstream products in the market, with a market share of more than 60%. Electric water heaters are divided into two types: water storage type and instant heating type, and the use of electric water heaters has the following problems: [0003] (1) Scaling problem. Because the electric heating tube is in contact with water, the temperature difference will cause scaling, and even in some cases, the scaling of the water heater is very serious, which affects the heating efficiency. The existence of scale not only wastes ene...

AI Technical Summary

Problems solved by technology

Since the electric heating tube is in contact with water, the temperature difference will lead to scaling, and even in some cases, the scaling of the water heater is very serious, which affects the heating efficiency

The presence of scale not only wastes energy, but also affects the health of users

[0004] (2) Safety issues

At present, electric water heaters are not separated from water and electricity, and there is a risk of leakage

[0005] (3) Lack of personalized design

However, due to its structural limitations, it is difficult to design the water heater into other shapes

Moreover, light, thin and short design is the development trend of home appliances, but in principle, the current design of water heaters cannot do this

[0006] Recently, energy storage devices that use phase change materials to store solar energy or electric energy for heat storage and then use have appeared one after another. However, these devices generally have complex structures, low heat transfer efficiency, and are difficult to produce in large quantities. In practical applications, there are problems of poor use effect
