[0027] Example:
[0028] like Figure 1-5 As shown, this embodiment proposes a dual-heat-source heating device, including a sealed chamber 1. A mounting frame 2 and an electric auxiliary hot water tank 3 are fixedly installed on one side surface of the sealed chamber 1. An electric heating tube 4 is installed inside the electric auxiliary hot water tank 3, and an inlet pipe 5 is fixedly installed on the electric heating tube 4. Low-temperature resistant coolant is injected into the electric auxiliary hot water tank 3 through the inlet pipe 5, and the electric heating tube 4 is energized to heat the coolant inside the electric auxiliary hot water tank 3. Two water pumps 6 and two fuel oil water heaters 7 are fixedly installed on the outer surface of the mounting frame 2. A first connecting pipe 8 is fixedly connected between the inlet ports of the two electric auxiliary hot water tanks 3 and the two water pumps 6. The two water pumps 6 and the two fuel oil water heaters 7 are started by the control system. When the two water pumps 6 are running, the heated coolant is drawn out from the electric auxiliary hot water tank 3 through the two first connecting pipes 8.
[0029] A second connecting pipe 9 is fixedly connected between the outlet port of the water pump 6 and the inlet port of the fuel-fired water heater 7. A first heat exchanger 10, a second heat exchanger 11, and a third heat exchanger 12 are installed on the bottom wall of the sealed chamber 1. A third connecting pipe 13 is fixedly installed at each of the two inlet ports of the first heat exchanger 10. The ends of the two third connecting pipes 13 furthest from the first heat exchanger 10 are respectively connected to the outlet ports of the two fuel-fired water heaters 7. After being transported through the two second connecting pipes 9 and the two fuel-fired water heaters 7, the coolant is transported to the first heat exchanger 10 through the two third connecting pipes 13. A fourth connecting pipe 14 is fixedly connected between the outlet port of the first heat exchanger 10 and the inlet port of the second heat exchanger 11. Connecting pipe 14 delivers coolant to the second heat exchanger 11. A fifth connecting pipe 15 is fixedly connected between the outlet port of the second heat exchanger 11 and the inlet port of the third heat exchanger 12. Coolant is then delivered to the third heat exchanger 12 through two fifth connecting pipes 15. Two return pipes 16 are fixedly connected between the outlet port of the third heat exchanger 12 and the electric auxiliary hot water tank 3. Finally, the heated coolant is reinjected into the electric auxiliary hot water tank 3 through the two return pipes 16, realizing a closed-loop circulation of the heated coolant. A water level sensor 17 is installed on the top wall of the electric auxiliary hot water tank 3, and a temperature controller 18 is installed on the inner wall of the electric auxiliary hot water tank 3. The temperature controller 18 can send a feedback signal to the control system regarding the temperature of the coolant inside the electric auxiliary hot water tank 3.
[0030] like Figure 1 , Figure 3 and Figure 4As shown, a protective shell 19 is fixedly installed on the outer surface of the mounting bracket 2. The two water pumps 6 and the two fuel water heaters 7 are located inside the protective shell 19. The protective shell 19 can provide external protection for the water pumps 6 and the fuel water heaters 7. An opening is provided on the lower end face of the protective shell 19. The opening can ensure ventilation and heat dissipation for the water pumps 6 and the fuel water heaters 7.
[0031] like Figure 2 As shown, the first heat exchanger 10, the second heat exchanger 11, and the third heat exchanger 12 have the same specifications, and the fourth connecting pipe 14, the fifth connecting pipe 15, and the return pipe 16 are all in pairs.
[0032] like Figure 3 As shown, the thermostat 18 is electrically connected to the water level sensor 17. The thermostat 18 can comprehensively judge the working status of the electric auxiliary hot water tank 3 based on the temperature it monitors and the liquid level information transmitted by the water level sensor 17.
[0033] The working principle of the above embodiment is as follows: First, the electric heating element 4, water pump 6, fuel water heater 7, first heat exchanger 10, second heat exchanger 11, third heat exchanger 12, water level sensor 17, and thermostat 18 are all electrically connected to the external control system. Low-temperature resistant coolant is injected into the electric auxiliary hot water tank 3 through the inlet pipe 5. Then, the electric heating element 4 is energized, which heats the coolant inside the electric auxiliary hot water tank 3. When the temperature of the coolant inside the electric auxiliary hot water tank 3 reaches 80 degrees Celsius, the thermostat 18 sends a feedback signal. Then, the control system starts the two water pumps 6 and the two fuel water heaters 7. When the two water pumps 6 are running, the heated coolant is drawn from the electric auxiliary hot water tank 3 through the two first connecting pipes 8. After being transported through the two second connecting pipes 9 and the two fuel water heaters 7, the coolant is transported to the first heat exchanger 10 through the two third connecting pipes 13, to the second heat exchanger 11 through the two fourth connecting pipes 14, and then to the third heat exchanger 11 through the two fifth connecting pipes 15. In the third heat exchanger 12, the heated coolant is finally reinjected into the electric auxiliary hot water tank 3 through two return pipes 16. With the continuous operation of the electric heating tube 4, water pump 6, oil water heater 7, first heat exchanger 10, second heat exchanger 11, third heat exchanger 12 and thermostat 18, the heated coolant can be circulated in a closed loop, thereby heating the internal environment of the sealed chamber 1 and effectively preventing the external environment from convectively contacting the inside of the sealed chamber 1. At the same time, if the temperature difference between the inside and outside is large and the environment is cold, and the coolant temperature is below 60 degrees Celsius, the electric heating tube 4 alone cannot meet the heating requirements. The two oil water heaters 7 start combustion and supply 10kW of heating power to heat the circulating coolant through fuel oil, thereby ensuring the heating requirements of the internal environment of the sealed chamber 1. When the coolant temperature is above 80 degrees Celsius, the oil water heater 7 stops igniting and continues to circulate the coolant. This application can automatically select electric heating, fuel oil heating or full power heating modes according to the ambient temperature, which is more flexible overall.
[0034] In this application, the water level sensor 17 is model number SCJ-LD07, and the temperature controller 18 is model number KSD305. Both the water level sensor 17 and the temperature controller 18 are known prior art, and their working principles and usage methods will not be described in detail here.
[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
