[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 、 Figure 2 As shown, this embodiment discloses a window-type solar heating device, including a heating device chassis 1 , with wheels installed at the bottom of the heating device chassis 1 , thereby forming a movable trolley-type heating device chassis 1 .

[0020] Mounted on the heater chassis 1 are a copper tube-in-fin heat exchanger 2, a water tank 4, and a water pump 9. The water tank 4 stores clean water for heat transfer. A water inlet is located at the top of the tank, allowing fresh water to be added. A transparent window 4a is located on the rear side of the tank, allowing the liquid level inside to be observed, indicating whether the tank is full. The front of the tank 4 features a water outlet 4b, a water inlet 4c, and an electric heating port. A drain valve is located at the bottom of the tank, allowing unused water to be drained. A solar panel 10 is located on the right side of the tank 4. This panel absorbs sunlight and transfers heat to the water inside, heating it to hot water.

[0021] The water inlet of the water pump 9 is connected to the water outlet port 4b of the water tank 4 via a connecting pipe. The water outlet of the water pump 9 is connected to one port of the copper tube-in-fin heat exchanger 2 via a connecting pipe 7. The other port of the copper tube-in-fin heat exchanger 2 is connected to the water inlet port 4c of the water tank 4 via a connecting pipe. Thus, a water circulation loop is formed by the water tank 4, the water pump 9, and the copper tube-in-fin heat exchanger 2. In this water circulation loop, the water pump 9 draws hot water from the water tank 4 and then transfers the hot water to the copper tube-in-fin heat exchanger 2 via a connecting pipe. After being cooled by the copper tube-in-fin heat exchanger 2, the water returns to the water tank 4 via a connecting pipe. In this way, water is continuously circulated in the water circulation loop under the water pump's supply.

[0022] An axial flow fan 3 is integrated on the left side of the copper tube sleeve fin heat exchanger 2. When the axial flow fan 3 rotates, it can extract air. When the indoor air flows through the copper tube sleeve fin heat exchanger 2, it returns to the room under the action of the axial flow fan 3. When the air flows through the copper tube sleeve fin heat exchanger 2, it can exchange heat with the water flowing in the copper tube sleeve fin heat exchanger 2, thereby heating the space where the heater is located. The heating principle of the heater is shown in Figure 3 .

[0023] The electric heating interface of the water tank 4 is installed with an electric heating pipe 8. When the water temperature in the water tank 4 is too low, the electric heating pipe 8 can reheat the water in the water tank 4 to raise it to the required temperature.

[0024] A heater housing 5 is also mounted on the heater chassis 1. This housing encloses the water tank 4, water pump 9, and copper-tube-and-fin heat exchanger 2, protecting all components. The front and rear sides of the heater housing 5 have openings serving as the heater air inlet 5a. The left side of the housing 5 has an opening serving as the heater air outlet 5b. The heater air inlet 5a corresponds to the copper-tube-and-fin heat exchanger 2, while the heater air outlet 5b corresponds to the outlet side of the axial fan 3.

[0025] A controller 6 is mounted on the heater housing 5 . The controller 6 is electrically connected to a return air temperature sensor and a water tank temperature sensor for signal transmission. These sensors sense the indoor return air temperature at the heater's air inlet and the water temperature in the water tank 4 , respectively, and transmit their collected signals to the controller 6 . The controller 6 is also electrically connected to a water pump 9 , an axial flow fan 3 , and an electric heating tube 8 . The controller 6 controls the operation or deactivation of these three elements, thereby controlling the heater's heating operation.

[0026] Before using this embodiment, the water tank 4 should be filled with clean water, and the heater should be placed on the windowsill where sunlight can directly reach it. In this way, the solar heat absorbing plate 10 of the heater absorbs the energy of sunlight, heating the clean water in the water tank 4 and storing heat.

[0027] During operation, the axial flow fan 3 rotates to extract indoor air, and the return air temperature sensor senses the indoor return air temperature. When the indoor temperature (the temperature at the return air outlet of the heater) is lower than the return air temperature set value of the controller 6, the controller 6 controls the water pump 9 and the axial flow fan 3 to work. The water pump 9 extracts hot water from the water outlet interface of the water storage tank 4 through the connecting pipe, and then inputs the hot water from an interface of the copper tube sleeve fin type heat exchanger 2 into the copper tube sleeve fin type coil heat exchanger 2 through the connecting pipe 7. The indoor air enters the heater from the heater air inlets 5a on the front and rear sides of the heater, flows through the outer surface of the fins 2 of the copper tube sleeve fin type heat exchanger to exchange heat with the hot water, and then blows out from the heater air outlet 5b of the heater. The heater air outlet 5b transmits high-temperature air that has absorbed the heat of the hot water to the outside, thereby heating the space where the heater is located. Finally, the hot water that has passed through the copper tube sleeve fin type heat exchanger 2 and undergone heat exchange is transported back to the water storage tank 4 from the water inlet interface through the pipeline.

[0028] The water tank temperature sensor in controller 6 senses the temperature of the hot water in water tank 4. When the water temperature in water tank 4 falls below the set point, controller 6 activates electric heating pipe 8 to reheat the cooled water in water tank 4, raising it to the desired temperature before deactivating. When the indoor temperature reaches the return air temperature set by controller 6, controller 6 deactivates water pump 9 and axial fan 3. Solar panels 10 continuously absorb sunlight, heating the water in water tank 4 and storing the heat for later use.

[0029] This embodiment can heat the entire enclosed room, and can also close the door of a separate room and place it in the separate room to heat the separate enclosed room independently.
