In addition, the forms of each structure described in the following embodiments are merely examples, and a solar-based water heat exchange device related to the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0022] Embodiment 1:
[0023] As Figures 1-4As shown in the figure, a solar-based water heat exchange device includes a water storage tank 1 and a solar collector 2. A pipeline medium circulation mechanism 3 is provided between the water storage tank 1 and the solar collector 2. The pipeline medium circulation mechanism 3 includes a first heat-insulating medium conduit 31.

The bottom end of the medium heat dissipation pipe 33 is fixedly installed at one end of the second connector 34.
[0024] In this embodiment, through the setting of the solar collector 2, it is convenient to absorb solar energy, so that
[0025] the temperature of the solar collector 2 rises rapidly. The fluid heat-conducting medium inside it expands due to heat and has a smaller density, so it naturally rises. Through the cooperation of the first water pump 311 and the first heat-insulating medium conduit 31, it is convenient to extract the fluid heat-conducting medium and discharge it into the medium heat dissipation pipe 33 through the first connector 32 to exchange heat with the water in the water storage tank 1, making the water in the tank warm up.

At this time, the fluid heat-conducting medium inside the solar collector 2 expands due to heat in the same way and is extracted through the first water pump 311 and the first heat-insulating medium conduit 31, so that the fluid heat-conducting medium can circulate to operate and exchange heat with the water inside the water storage tank 1.
[0026] Embodiment Two:
[0027] As Figures 1-4As shown in the figure, a uniform heat exchange mechanism 4 is provided on the right side of the water storage tank 1.

The right end of the one-way check valve 431 is a one-way water inlet end, and the left end of the one-way check valve 431 is a one-way water outlet end. An annular conduit 44 is provided above the inner cavity of the water storage tank 1. One end of the second heat-insulated drain pipe 432 is fixedly connected to one side of the annular conduit 44, and one end of the second heat-insulated drain pipe 432 communicates with the inside of the annular conduit 44. Connecting rods 46 are fixedly connected to both sides of the top of the annular conduit 44. The top ends of the connecting rods 46 are fixedly connected to the top of the inner cavity of the water storage tank 1. A plurality of nozzles 45 are fixedly installed at the bottom of the annular conduit 44. A motor 47 is fixedly installed in the middle of the top of the water storage tank 1. The output end of the motor 47 extends into the inner cavity of the water storage tank 1 and is fixedly connected to a rotating shaft 48.

An inlet 11 is provided on the left side of the top of the water storage tank 1. A drain pipe 12 is fixedly installed in the middle of the bottom of the water storage tank 1. A drain valve 13 is installed on the drain pipe 12.
[0028] In this embodiment, through the settings of the heat-insulated water suction pipe 41 and the second water pump 42, it is convenient to extract the cold water at the lower part inside the water storage tank 1, and discharge it into the annular conduit 44 through the first heat-insulated drain pipe 43, the one-way check valve 431 and the second heat-insulated drain pipe 432. At this time, it is sprayed into the hot water above the inside of the water storage tank 1 through a plurality of nozzles 45. Then, through the cooperation of the motor 47, the rotating shaft 48 and the stirring rod 49, the water above the inside of the water storage tank 1 is stirred, so that the cold and hot water is quickly mixed, improving the uniformity of heating the water inside the water storage tank 1. Through the setting of the inlet 11, it is convenient to add water to the inside of the water storage tank 1. Through the settings of the drain pipe 12 and the drain valve 13, when the drain valve 13 is opened, it is convenient to discharge the water inside the water storage tank 1 through the drain pipe 12.
[0029] To sum up, as Figures 1-4As shown, for this solar-based water heat exchange device, during use, when irradiated by the sun, the temperature of the solar collector 2 rises rapidly.

The fluid heat-conducting medium is pumped into the medium heat dissipation tube 33 through the first water pump 311, the first heat-insulating medium conduit 31, and the first connector 32 to exchange heat with the water in the water storage tank 1. At this time, the temperature of the fluid heat-conducting medium decreases, and with a smaller density, it flows back into the interior of the solar collector 2 through the bottom end of the medium heat dissipation tube 33, the second connector 34, and the second heat-insulating medium conduit 35, and the fluid heat-conducting medium circulates in the same way to exchange heat with the water inside the water storage tank 1, raising the temperature of the water inside the water storage tank 1. During the process of the water inside the water storage tank 1 exchanging heat and rising in temperature, the cold water at the lower part inside the water storage tank 1 is pumped out through the heat-insulating water extraction pipe 41 and the second water pump 42, and is discharged into the annular conduit 44 through the first heat-insulating drain pipe 43, the one-way check valve 431, and the second heat-insulating drain pipe 432. At this time, it is sprayed into the hot water above the water storage tank 1 through multiple nozzles 45, and then the output end of the motor 47 drives the rotating shaft 48 and the stirring rod 49 to rotate, stirring the water above the water storage tank 1, so that the cold and hot water are quickly mixed, improving the uniformity of heating the water inside the water storage tank 1.
