Background

The solar water heater is a heating device for converting solar energy into heat energy, and heats water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. With the improvement of awareness of environmental protection, the use of solar energy, which is a green energy source, is increasing, and the most widely used solar water heater is embodied, and a water tank in the solar water heater is an important component of the solar water heater. The water tank is used for storing heated hot water, and is convenient for people to use at any time. However, the temperature difference between day and night is large in the autumn and winter, if the heat preservation performance of the water tank is not good enough, the hot water in the water tank is difficult to keep at a high temperature for a long time, and if people need to use the hot water at night, the water temperature at the moment can not meet the requirement.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the thermal insulation water tank comprises a shell 1, an inner container 2 and a thermal insulation layer 3 arranged between the shell 1 and the inner container 2, wherein a heat collection plate 4 is arranged at the top of the shell 1, and the heat collection plate 4 is mounted on the shell 1 through a fixing support 5. The heat collecting plate 4 lower part cavity forms a heat conduction chamber 6, heat conduction chamber 6 bottom is equipped with a plurality of annular heat pipes 7 rather than the intercommunication, heat pipe 7 runs through shell 1 and surrounds on the outer wall of inner bag 2, and two ports of heat pipe 7 all communicate with heat conduction chamber 6, fill phase change heat storage material in heat conduction chamber 6 and the heat pipe 7, phase change heat storage material can be in heat conduction chamber 6 and the heat pipe 7 mesocycle flow. The two ends of the inner container 2 are respectively provided with a water inlet 8 and a water outlet 9, wherein the water inlet 8 is arranged at the lower part of one end of the inner container 2, cold water enters the inner container 2 from the lower part, the water outlet 9 is arranged at the higher part of the other end of the inner container 2, and hot water flows out from the higher part. The phase change heat storage material is a solid-liquid phase change heat storage material, when the phase change heat storage material absorbs heat, the phase change heat storage material is changed from a solid state to a liquid state and can freely flow in the heat conduction cavity and the heat conduction pipe, and when the liquid phase change heat storage material releases heat, the temperature of the liquid phase change heat storage material is reduced and is condensed into a solid state again. An electric heating wire 10 is arranged in the heat conduction cavity 6, and the electric heating wire 10 is used for heating the phase change heat storage material in the heat conduction cavity 6. The utility model discloses holding water box, the installation of its thermal-collecting tube is the same with the mounting means of current solar water heater thermal-collecting tube, all installs the thermal-collecting tube in the lower part of water tank and makes it be linked together with the inner bag, and this is prior art, no longer gives unnecessary details.

The utility model discloses during the use, daytime, solar illumination is strong, a large amount of heats are absorbed to thermal-arrest board 4, and transmit to in the heat conduction chamber 6, make the phase change thermal storage material temperature in the heat conduction chamber 6 rise and form liquid, absorptive heat continues toward the transmission of heat pipe 7 department, also heat the phase change thermal storage material in the heat pipe 7 and make it form liquid, at this moment, the heat is saved in the phase change thermal storage material, evening has arrived, ambient temperature descends, phase change thermal storage material release heat, and these heats will play fine heat preservation effect to the hot water in inner bag 2, the heat loss of hot water in the inner bag has been avoided. When the external temperature is too low and the heat collecting plate 4 cannot collect enough heat, the phase change heat storage material in the heat conducting cavity 6 can be heated through the heating wire 10, and the heat is transferred to the heat conducting pipe 7, so that the water in the inner container 2 is heated, and the requirement of people on using hot water is met.

Finally, it should be noted that: these embodiments are merely illustrative of the present invention and do not limit the scope of the invention. In addition, other variations and modifications will be apparent to persons skilled in the art based on the foregoing description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
