Energy storage sleeve and energy storage electric water heater

Abstract

An energy storage sleeve comprises an outer pipe, an inner pipe, sealing covers, phase change energy storage materials and fins arranged on the outer wall of the inner pipe; the inner pipe is sleeved with the outer pipe in a concentric mode, and the two end openings of the outer pipe are sealed through the sealing covers; the two end openings of the inner pipe penetrate through the sealing covers respectively, so that a closed containing cavity is formed between the inner wall of the outer pipe and the outer wall of the inner pipe; the phase change energy storage materials are arranged inside the containing cavity; the disc-shaped fins are arranged on the outer wall of the inner pipe. The energy storage electric water heater is composed of a heat preservation shell, an electric energy storage heat exchange body and a temperature control device; the electric energy storage heat exchange body comprises the energy storage sleeves, inner pipe connecting bends and an electrical heating element; a cold water port and a hot water port are formed in one side edge of the heat preservation shell; the two end openings of every two adjacent energy storage sleeves are connected through the corresponding inner pipe connecting bend, and an S-shaped heat exchange body channel is formed; one end of the heat exchange body channel is connected with the cold water port, and the other end of the heat exchange body channel is connected with the hot water port; the electrical heating element is arranged at the end of the electric energy storage heat exchange body or on the outer wall of the corresponding energy storage sleeve.

Description

technical field [0001] The invention belongs to the technical field of water heaters, bathroom products, energy storage and energy saving, and in particular relates to the technology of an energy storage casing and an energy storage electric water heater. Background technique [0002] With the improvement of people's living standards and the comfort requirements for working and living environments, the consumption of electric energy has increased significantly, resulting in excessive energy consumption, increased environmental pollution, excessive peak and valley loads on the power grid, and serious shortage of power supply during peak loads. Such as the increase of building energy consumption. At present, the building energy consumption in developed countries in Europe and the United States has reached 40% of the total energy consumption of the whole society. In my country, building energy consumption accounts for about 30% of the total energy consumption in the country. With...

Problems solved by technology

[0005] In the existing market, there are very few civil electric energy storage water heaters, and the traditional water storage water heaters are too bulky, especially large-capacity water heaters; while air energy water heaters are energy-saving, but they are expensive, noisy, troublesome to install, Disadvantages such as large volume, especially when the external ambient temperature is too low, the operation situation will be very difficult
