Energy-saving and environment-friendly water heating equipment

Abstract

The invention discloses energy-saving and environment-friendly water heating equipment. The equipment comprises a water heater shell and a plurality of light wave heating pipes arranged in the water heater shell, wherein at least one heat absorption plate is arranged in the water heater shell; a heat exchange device for heat exchange with the heat absorption plate is fixedly arranged on the heat absorption plate; the heat exchange device is provided with a water inlet extending from the lower part of the water heater shell and a water outlet extending from the upper part of the water heater shell; and the surface of the heat absorption plate is coated with a selective heat absorption coating. After the selective heat absorption coating absorbs the energy of the light emitted by the light wave heating pipes, heat is conducted to the heat exchange device through the heat absorption plate to heat the water in the heat exchange device, the heat efficiency is high, electric heating can be replaced, the safety and reliability are high, and the service life is long. The water heater has the advantages that the size is small, the space of installation is saved, the water heater shell can be machined into a flat shape for easy and flat installation with a wall body, and the water heater can be used as a water heater as well as as an auxiliary heating device of a solar water heater.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly hot water equipment. Background technique [0002] Traditional water heaters are electric water heaters or gas water heaters. Electric water heaters use electricity to directly heat, which is prone to electric leakage and injury accidents, and has poor safety and reliability. Gas water heaters use coal gas, natural gas or liquefied petroleum gas as fuel for heating, and are also prone to gas poisoning, with poor safety and reliability. Moreover, the electric water heater or the gas water heater has a large volume, needs to occupy a large space during installation, and has low thermal efficiency. [0003] In addition, solar water heaters mainly use solar energy to produce hot water, but at night or when the sun is not good, the hot water produced by solar water heaters may not be able to meet the needs of production and life. Connected to heat the water in the circulation pipeline to m...

Problems solved by technology

[0002] Traditional water heaters are electric water heaters or gas water heaters. Electric water heaters use electricity to directly heat, which is prone to electric leakage and injury accidents, and has poor safety and reliability.

Gas water heaters use coal gas, natural gas or liquefied petroleum gas as fuel for heating, and are also prone to gas poisoning, with poor safety and reliability

In addition, electric water heaters or gas water heaters are large in size, need to occupy a large space during installation, and have low thermal efficiency.

[0003] In addition, solar water heaters mainly use solar energy to produce hot water, but at night or when the sun is not good, the hot water produced by solar water heaters may not be able to meet the needs of production and life. connection, to heat the water in the circulation pipeline to meet the needs of production and life, but the traditional auxiliary heating device has low thermal efficiency, cannot achieve water and electricity isolation, has poor safety and reliability, is easy to scale, and has a short service life
