[0032] Example
[0033] This embodiment provides a heating device that integrates fuel heating and pure electric heating, such as... Figure 1 As shown, it includes: a pure electric heater control head 200, a fuel oil heating control head 300, and a heat exchanger 100 shared by both.
[0034] like Figure 2 As shown, the heat exchanger 100 includes a combustion chamber 8 and an antifreeze delivery layer 9; the heat in the combustion chamber 8 can be transferred to the antifreeze delivery layer 9. The combustion chamber 8 is a chamber for fuel to enter and burn, and the antifreeze delivery layer 9 circulates antifreeze, which absorbs heat and carries the heat outside the heat exchanger 100 for heat exchange.
[0035] The pure electric heater control head 200 is connected to one end of the heat exchanger 100 and is used to supply electricity to heat the antifreeze, thereby raising the temperature of the antifreeze.
[0036] The fuel heating control head 300 is connected to the other end of the heat exchanger 100 and is used to introduce fuel into the combustion chamber 8 and ignite it.
[0037] The integrated fuel heating and pure electric heating device provided in this embodiment connects the pure electric heater control head 200 and the fuel heating control head 300 to the same heat exchanger 100, resulting in a compact structure. Both share the antifreeze delivery layer 9 of the heat exchanger 100, reducing the total number of parts. The pure electric heater control head 200 heats the antifreeze delivery layer 9, while the fuel heating control head 300 transfers heat to the antifreeze delivery layer 9 through the combustion chamber 8. This allows the antifreeze to be selectively heated by either fuel or pure electric means, integrating two heating methods and reducing component costs and subsequent maintenance expenses.
[0038] The reason why the integrated heating device for fuel heating and pure electric heating in this embodiment achieves a compact structure is that the pure electric heater control head 200 and the fuel heating control head 300 are respectively connected from both ends of the heat exchanger 100, making full use of the space at both ends of the heat exchanger 100, resulting in a compact overall structure without affecting the function.
[0039] The integrated heating device combining fuel heating and pure electric heating provided in this embodiment can be used in scenarios including but not limited to the following:
[0040] 1. Before driving in cold winter, the fuel heating control head 300 can be used to preheat the battery;
[0041] 2. When the vehicle's battery is low, the fuel heating control head 300 can be used to heat the entire vehicle, which also increases the battery's range.
[0042] In an alternative embodiment, such as Figure 2 As shown, the heat exchanger 100 also includes a heat dissipation layer 5 and a heating rod 7; the heat dissipation layer 5 is located outside the combustion chamber 8, and the antifreeze delivery layer 9 is located outside the heat dissipation layer 5, so that the heat in the combustion chamber 8 can be transferred to the antifreeze delivery layer 9 through the heat dissipation layer 5; the heating rod 7 is located inside the antifreeze delivery layer 9; the pure electric heater control head 200 is used to energize and heat the heating rod 7.
[0043] The heat dissipation layer 5 is located outside the combustion chamber 8, surrounding the outer wall of the combustion chamber 8. It can conduct the heat generated by combustion. The heat generated by combustion in the combustion chamber 8 is transferred to the antifreeze delivery layer 9 through the heat dissipation layer 5, resulting in high thermal conductivity. Furthermore, arranging the antifreeze delivery layer 9 and the heat dissipation layer 5 around the combustion chamber 8 does not significantly increase the size of the equipment.
[0044] In an alternative embodiment, such as Figure 2 As shown, the heat exchanger 100 also includes a first temperature sensor 12 and a second temperature sensor 14. Both the first temperature sensor 12 and the second temperature sensor 14 are connected to the antifreeze delivery layer 9 to monitor the temperature of the antifreeze delivery layer 9. The first temperature sensor 12 is electrically connected to the pure electric heater control head 200, and the second temperature sensor 14 is electrically connected to the fuel heating control head 300. In this embodiment, the pure electric heater control head 200 and the fuel heating control head 300 each use two temperature sensors, enabling independent control under different heating methods for the antifreeze.
[0045] In an optional embodiment, the integrated heating device for fuel heating and pure electric heating of this embodiment, such as... Figure 2 As shown, the heat exchanger 100 also includes a housing 1, which has an inlet pipe 3 for antifreeze to enter and an outlet pipe 11 for antifreeze to exit. In this embodiment, the antifreeze delivery layer 9 is disposed inside the housing 1, and the housing 1 is also the outer wall of the antifreeze delivery layer 9. The inner wall of the antifreeze delivery layer 9 is the outer wall 15 of the heat dissipation layer. In this way, antifreeze can flow within the antifreeze delivery layer 9 through the inlet pipe 3 and the outlet pipe 11.
[0046] In an alternative embodiment, such as Figure 2 As shown, the heat exchanger 100 also includes an exhaust screw 2, which is connected to the side wall of the water inlet pipe 3 and is used to allow air to escape from inside the water inlet pipe 3. In this embodiment, the exhaust screw 2 is usually closed to the side wall of the water inlet pipe 3. When it is necessary to release gas from the water inlet pipe 3, the exhaust screw 2 can be unscrewed to release the gas, making the venting operation more convenient.
[0047] In an alternative embodiment, such as Figure 2As shown, the heat exchanger 100 also includes an exhaust pipe 6, one end of which is connected to the combustion chamber 8, and the other end extends to the outside of the antifreeze delivery layer 9, i.e., the outside of the outer shell 1. In this embodiment, by designing the exhaust pipe 6 to pass through the heat dissipation layer 5 and the antifreeze delivery layer 9, the combustion exhaust gas in the combustion chamber 8 can be discharged to the outside.
[0048] In an alternative embodiment, such as Figure 2 As shown, the heat exchanger 100 also includes a temperature limiter 13, which monitors the temperature within the antifreeze delivery layer 9 and cuts off the power supply from the pure electric heater control head 200 to the heating rod 7 when the temperature exceeds the limit. In this embodiment, the temperature limiter 13 serves as a safety redundancy; when the parameters or control of the temperature sensor are abnormal, the temperature limiter 13 cuts off the power supply, thereby improving the safety of the device.
[0049] In an alternative embodiment, such as Figure 2 As shown, the heat exchanger 100 has an end cap at its end for sealing the combustion chamber 8 and the antifreeze delivery layer 9. The end cap has an opening corresponding to the position of the antifreeze delivery layer 9, and the opening is sealed by a blind plug 10. In this embodiment, the end cap is used to seal the combustion chamber 8 and the antifreeze delivery layer 9, and the reserved opening in the end cap is then sealed by the blind plug 10, increasing the expandability of the device for later addition of parts.
[0050] In an alternative embodiment, such as Figure 2 As shown, the heating rod 7 includes a main body and an electrode part 71, which is fixed to the outside of the end cap. In this embodiment, the electrode part 71 is designed to be on the outside of the end cap to avoid contact with antifreeze, ensure stable power transmission, and facilitate docking with the pure electric heater control head 200.
[0051] In an alternative embodiment, such as Figure 2 As shown, the heat exchanger 100 also includes a mounting bracket 4 fixed to the housing 1. The mounting bracket 4 is used for fastening components so that the device can be fixed to a vehicle.
[0052] In an alternative embodiment, such as Figure 2 As shown, 4 to 8 heating rods 7 are arranged around the antifreeze delivery layer 9. Preferably, there are 6 heating rods to make the heating of the antifreeze more uniform.
[0053] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
