[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] This utility model provides a solar-to-electricity-to-heat device for use in heating systems. It converts electrical energy generated by a solar power generator into heat energy for heating. The device includes: a heater 102 for connecting to the solar power generator; and a heat transfer pipe 101, which includes a heating section, a water storage section, and a heat dissipation section. The heating section connects to the heater 102, the water storage section connects to an insulated water tank (not shown in the figure), and the heat dissipation section connects to a heat dissipation device. The heat transfer medium is the medium for transferring heat energy, and this medium is typically water.

[0028] In implementation, a water pump set is installed on the heat medium conveying pipeline 101. A heater 102 is connected to the heating section of the heat medium conveying pipeline 101. The heater 102 is connected to an external solar power generation device. The water storage section of the heat medium conveying pipeline is connected to an external water storage tank, and the heat dissipation section is connected to a heat dissipation device. After the heat medium conveying pipeline is filled with water, the heater 102 heats the water in the pipeline during the day. Driven by the water pump set, the water flows through the water storage section into the water storage tank. The heated water is stored in the water storage tank, and the water in the water storage tank also flows back into the heat medium conveying pipeline under the drive of the water pump set, forming a circulation. Driven by the water pump set, the heated water also flows through the heat dissipation section into the heat dissipation device, and simultaneously, the water is dissipated... Water in the heating equipment also flows back into the heat transfer pipe to form a cycle. The heat transfer pipe is the main component for water heating and also the intermediate component for water circulation. At night, the heater 102 is no longer powered, and the water in the heat transfer pipe is no longer heated. At this time, the water pump set can pump the hot water in the storage tank back into the heat transfer pipe through the storage section. The water pump set then pumps the hot water pumped back from the storage tank into the heat dissipation equipment through the heat dissipation section of the heat transfer pipe. The hot water heated during the day is stored in the storage tank, and the hot water flows back into the heat dissipation equipment through the storage section of the heat transfer pipe 101. This allows the heat transfer pipe to connect to the storage tank to allow hot water circulation even when there is no solar power to supply electricity to the heater 102 at night, ensuring heating at night.

[0029] Furthermore, the heat medium conveying pipeline 101 is composed of multiple short pipes spliced ​​together. The multiple short pipes are connected to form the heat medium conveying pipeline 101. The heat medium conveying pipeline 101 as a whole includes a drain pipe and a return pipe. The heating part includes a section of drain pipe and a section of return pipe. The water storage part includes a section of drain pipe and a section of return pipe. The heat dissipation part includes a section of drain pipe and a section of return pipe. The heating part, heat dissipation part, and water storage part are spliced ​​together to form the complete heat medium conveying pipeline 101. The drain pipe is used for water outflow, and the return pipe is used for water return. The drain pipe and the return pipe work together to realize water circulation. There are two water storage tanks. The corresponding heat medium conveying pipeline 101 has two water storage parts. One water storage tank is connected to one water storage part. By setting two water storage tanks, the storage capacity of hot water is increased to ensure sufficient hot water supply at night. In some cases, more than three water storage tanks can also be set.

[0030] Furthermore, the heater 102 can be one of an electromagnetic heater 102, an electric heating wire heater 102, or a thermal oil heater 102.

[0031] In some embodiments, the electro-heating device 1 is provided with a temperature control component, which includes a controller 103 and a touch screen 104. The controller 103 is electrically connected to the touch screen 104 and is also electrically connected to the heater 102.

[0032] In practice, the controller 103 is electrically connected to the touch screen 104 and the heater 102. A preset temperature is set on the touch screen 104, and the heating power of the heater 102 is controlled by the controller 103 to keep the heating temperature at the preset temperature value.

[0033] In some embodiments, the water storage section is provided with a first solenoid valve 105, the heat dissipation section is provided with a second solenoid valve 106, and the water pump group includes a first water pump 107 and a second water pump 108. The first water pump 107 is provided on the water storage section, and the second water pump 108 is provided on the heat dissipation section.

[0034] In implementation, the heater 102 is connected to the heating pipe, and a first solenoid valve 105 is installed on the water storage section.

A second solenoid valve 106 is installed on the heat dissipation section. The second solenoid valve 106 is used to control the water flow between the heat medium conveying pipe 101 and the external radiator. A first water pump 107 is installed on the water storage section. The first water pump 107 is used to pump in or out the water flow between the heat medium conveying pipe 101 and the water storage tank. A second water pump 108 is installed on the heat dissipation section. The second water pump 108 is used to pump in or out the water flow between the heat medium conveying pipe 101 and the heat dissipation water pipe 201.

[0035] Furthermore, the heat transfer pipeline 101 includes a drain pipe and a return pipe. A first solenoid valve 105 is provided on both the drain pipe and the return pipe of the water storage section. Similarly, the heat dissipation section includes a drain pipe and a return pipe. A second solenoid valve 106 is provided on both the drain pipe and the return pipe of the heat dissipation section.

[0036] In some embodiments, a temperature sensor is installed on the heat transfer pipeline, and the temperature sensor is connected to the controller.

[0037] In practice, the temperature sensor is used to measure the water temperature inside the heat medium conveying pipeline. The temperature sensor is connected to the controller 103 to control the heating temperature of the heater 102. If the temperature inside the heat medium conveying pipeline is higher than the predetermined value, the temperature sensor will detect an abnormal signal and transmit the abnormal signal to the controller 103. The controller 103 will then lower the heating temperature of the heater 102, thereby reducing the water temperature inside the heat medium conveying pipeline 101.

[0038] In some embodiments, the solar electrothermal conversion device includes a housing, and the heater and heat transfer pipe are disposed within the housing.
