Water-tank-free solar energy storage water heater

Abstract

The invention provides a water-tank-free solar energy storage water heater, which comprises an energy storage box, an energy storage box bracket, an energy storage box heat insulation cover, a heat collector framework, a transmission device and a control switch, wherein the transmission device and the control switch are arranged in the heat collector framework, through adopting a sunlight direct braising and burning mode, solar energy is directly stored into a box body provided with phase change energy storage materials, certainly, a solar absorption layer is arranged on the upper surface of the box body, meanwhile, the water-tank-free solar energy storage water heater is directly connected into an urban tap water system through a coil pipe arranged in the energy storage box body, cold water entering the coil pipe is subjected to heat exchange through the phase change materials arranged in the energy storage box, required hot water is directly discharged, assemblies such as an additional water storage water tank, a traditional heat collector and a water pump are not needed, the opening and the closing of the energy storage box heat insulation cover can be realized through an optical control switch, a temperature controller and a temperature sensor, and the high automation and intelligence can be realized. The water heater can be perfectly combined with a balcony railing, and can also be freely placed onto a roof or hung on a wall.

Description

technical field [0001] The invention relates to a solar heat collecting device and belongs to the technical field of solar water heaters, in particular to a technology of a tankless solar energy storage water heater. Background technique [0002] Today, in terms of solar energy utilization, 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. Solar radiation is affected by day and night, seasons, and rainy and snowy weather factors, showing discontinuity and instability. The reason is that the system mainly uses water tanks for heating. Hot water is a sensible heat, and the energy storage is far from enough. , and the water tank still has the following defects in the use process: 1. The water tank is large in volume.

[0002] Today, in terms of solar energy utilization, 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. Solar radiation is affected by day and night, seasons, and rainy and snowy weather factors, showing discontinuity and instability. The reason is that the system mainly uses water tanks for heating. Hot water is a sensible heat, and the energy storage is far from enough. , and the water tank still has the following defects in the use process: 1. The water tank is large in volume. On the one hand, when the water consumption is small, the water circulation is slow, resulting in the inability to exchange heat in time, affecting the use of users, and there is some dead water space, which is easy to breed bacteria. Hygienic; on the other hand, the installation and placement of the bulky water tank is inconvenient, and at the same time, the water tank is filled with water for a long time, and there is a possibility of water leakage; electricity consumption

2. When the water tank is heated to a certain temperature, heat exchange cannot be performed to heat the water in the water tank. If the water tank continues to be heated, the water in the water tank will overheat; if the water tank is not continued to be heated, the heat collector will overheat and damage the heat collector

However, this set of technical processes is complicated, the manufacturing cost is too high, and the temperature in the vacuum heat collecting tube may be overheated and other problems still exist.
