Phase change heat collecting and energy storage integrated solar water heater

Abstract

The invention relates to a solar water heater, in particular to a phase change heat collecting and energy storage integrated solar water heater. An inner container coaxial with a casing is disposed inthe casing, a heat exchange coil pipe is disposed in the inner container, a phase change material storage portion is also disposed in the inner container, a cavity is formed between the casing and the inner container, a portion of the cavity is filled with a heat insulation layer, and another portion of the cavity is a greenhouse. One side of the casing is provided with a window, a light-transmitting cover plate is mounted on the window, and the light-transmitting cover plate and the greenhouse are located on the same side. A hot water outlet pipe is mounted on the upper portion of one side of the casing, a cold water inlet pipe is mounted on the lower portion of the same side, one end of the heat exchange coil pipe is communicated with the hot water outlet pipe, and the other end of theheat exchange coil pipe is communicated with the cold water inlet pipe. The phase change heat collecting and energy storage integrated solar water heater is simple and compact in structure, combines solar energy with a phase change material, and uses the phase change material to store the heat collected by the solar energy, is small and exquisite and has good popularization value.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a phase change solar water heater integrating heat collection and energy storage. Background technique [0002] Solar energy is an inexhaustible and inexhaustible renewable clean energy. At present, solar energy has been used in electricity, heating, etc. The use of solar energy can save a lot of fossil energy and reduce environmental pollution caused by energy use. . The technology of using solar energy to obtain medium and high temperature hot water required for life and heating has matured, but solar energy has a fatal weakness in life and heating utilization, that is, it is an intermittent energy source, and solar radiation is affected by day and night, seasons and The influence of rain and snow weather factors is manifested as discontinuity and instability. [0003] In addition, traditional solar water heaters include heat collectors, water storage tanks and various components to fo...

Problems solved by technology

This heating method must use a water storage tank and a medium circulation pipe, and for users who use this type of water heater, the installation of the water storage tank will occupy a certain amount of indoor space; in addition, the heat collector is installed outdoors through a fixed bracket, and the water storage tank Installed indoors, the two are connected by circulating pipes, which is easy to cause heat loss and low thermal efficiency
