Description

A high-efficiency new energy vehicle heater Technical Field

[0001] This invention relates to the field of automotive heating equipment technology, specifically to a high-efficiency new energy vehicle heater. Background Technology

[0002] In cold winters (even late autumn and early spring), car heating systems provide warmth to the vehicle's interior, raising the temperature. These systems heat the air inside the car or draw air in from outside, increasing the cabin temperature. With increasing societal demands for energy conservation and environmental protection, electric vehicles have become the future of modern automotive technology, leading to electric heating gradually replacing traditional car heating methods. However, due to the inherent structural limitations of electric heaters, dust or foreign objects are occasionally generated during operation. This means that when airflow enters the vehicle after being heated by the heater, it can bring dust or odors into the cabin as well. Summary of the Invention

[0003] In order to solve the technical problems existing in the background art, the present invention proposes a high-efficiency new energy vehicle heater.

[0004] This invention proposes a high-efficiency heater for new energy vehicles, comprising: a transition device, a pipe connector, and an electric heater, wherein:

[0005] The transition device has a chamber inside and has a first air inlet, a second air inlet, a first air outlet, and a second air outlet. The first air inlet and the first air outlet are respectively connected to the chamber. The chamber is equipped with a coil that connects the second air inlet and the second air outlet.

[0006] The pipe connector has a first pipe interface, a second pipe interface and a third pipe interface. The first pipe interface is connected to the second air outlet. The second pipe interface is provided with a first control valve for controlling the opening and closing of the interface. The third pipe interface is provided with a second control valve for controlling the opening and closing of the interface.

[0007] The electric heater has an air inlet and an air outlet, and the air outlet is connected to the second air inlet through an air concentrator.

[0008] Preferably, the transition device includes a front cover, a rear cover, and a main frame, wherein: the front cover and the rear cover are both funnel-shaped, the maximum end of the front cover is connected to and fixed to one end of the main frame, and the minimum end of the front cover has an opening to form a first air inlet; the maximum end of the rear cover is connected to and fixed to the other end of the main frame, and the minimum end of the rear cover has an opening to form a first air outlet; the coil is located inside the main frame.

[0009] Preferably, the main frame is a square frame, and the front and rear covers are both square funnel-shaped.

[0010] Preferably, both the second air inlet and the second air outlet are located on the main frame.

[0011] Preferably, it further includes an air inlet pipe, a first air outlet pipe, a second air outlet pipe, and a third air outlet pipe, wherein: the air inlet pipe is connected to the first air inlet; the first air outlet pipe is connected to the first air outlet; the second air outlet pipe is connected to the second pipe interface via a first control valve; and the third air outlet pipe is connected to the third pipe interface via a second control valve.

[0012] Preferably, the end of the second air outlet pipe furthest from the first control valve is connected to the first air outlet pipe.

[0013] Preferably, an odor detector is provided between the first pipe interface and the second air outlet; it also includes a controller, which is used to acquire the detection result of the odor detector and control the first control valve or the second control valve to open according to the acquired odor detection result.

[0014] Preferably, a dust detector is also provided between the first pipe interface and the second air outlet; the controller is used to obtain the detection result of the dust detector, and control the first control valve or the second control valve to enter the open state according to the obtained dust detection result.

[0015] In this invention, a first air inlet introduces low-temperature outside air into the chamber of the transition device; a second air inlet introduces high-temperature air discharged from the electric heater into the coil to exchange heat with the low-temperature air in the chamber, raising the temperature of the low-temperature air in the chamber to form warm air, and lowering the temperature of the high-temperature air discharged from the electric heater to form warm air; a first air outlet directs the warm air from the chamber into the vehicle for heating; a second air outlet guides the warm air discharged from the electric heater to a pipe connector, allowing the warm air discharged from the electric heater to be discharged through either the second or third pipe interface by selectively opening either the first or second control valve. This structural design allows air discharged from the second pipe interface to be introduced into the vehicle, while air discharged from the third pipe interface is introduced into the outside. If the driver notices an odor or dust in the heating airflow, they can directly direct the odor-laden airflow to the outside by switching the airflow discharge mode, thus solving the problem of odors or dust generated in the electric heater being introduced into the vehicle.

[0019] Referring to Figure 1, the present invention proposes a high-efficiency new energy vehicle heater, comprising: a transition device 1, a pipe connector 2, and an electric heater 3, wherein: the transition device 1 has a chamber inside, and the transition device 1 has a first air inlet a, a second air inlet b, a first air outlet c, and a second air outlet d; the first air inlet a and the first air outlet c are respectively connected to the chamber; a coil connecting the second air inlet b and the second air outlet d is provided in the chamber.

[0020] The pipe connector 2 has a first pipe interface, a second pipe interface, and a third pipe interface. The first pipe interface is connected to the second air outlet d. The second pipe interface is equipped with a first control valve 4 for controlling the on / off state of the interface, and the third pipe interface is equipped with a second control valve 5 for controlling the on / off state of the interface. The electric heater 3 has an air inlet end and an air outlet end. The air outlet end is connected to the second air inlet b through an air concentrator 6. The specific usage is as follows:

[0021] The first air intake is directly connected to the outside, guiding the airflow from the first air outlet into the vehicle. It also guides the airflow from the second pipe interface into the vehicle, while the airflow from the third pipe interface is directed to the outside. During heating, if the airflow from the electric heater 3 emits an odor, the driver can directly cut off the path of the electric heater 3 into the vehicle by closing the first control valve 4, allowing the function to operate solely from the airflow exiting the first air outlet. Simultaneously, closing the first control valve 4 and opening the second control valve 5 allows the airflow from the electric heater 3 to flow directly to the outside.

[0022] As described above, the first air inlet a of this invention introduces low-temperature air from the outside into the chamber of the transition device 1; the second air inlet b introduces high-temperature air discharged from the electric heater 3 into the coil to exchange heat with the low-temperature air in the chamber, thereby raising the temperature of the low-temperature air in the chamber to form warm air and lowering the temperature of the high-temperature air in the coil to form warm air; the first air outlet c pours the warm air from the chamber into the vehicle for heating; the second air outlet d guides the warm air in the coil to the pipe connector 2, and by selecting to open the first control valve 4 or the second control valve 5, the warm air in the coil is discharged from the second pipe interface or the third pipe interface. This structural design allows the air discharged from the second pipe interface to be introduced into the vehicle, and the airflow discharged from the third pipe interface to be introduced into the outside. When the driver discovers an odor or dust in the heating airflow, they can directly introduce the odorous airflow into the outside by switching the airflow discharge mode, thus solving the problem of odors or dust generated in the electric heater 3 being introduced into the vehicle.

[0023] Referring to Figure 2, the transition device 1 includes a front cover 101, a rear cover 102, and a main frame 103. Both the front cover 101 and the rear cover 102 are funnel-shaped. The largest end of the front cover 101 is connected to and fixed to one end of the main frame 103, and the smallest end of the front cover 101 has an opening to form a first air inlet a. The largest end of the rear cover 102 is connected to and fixed to the other end of the main frame 103, and the smallest end of the rear cover 102 has an opening to form a first air outlet c. The coil is located inside the main frame 103. During operation, the first air inlet guides external airflow to one side of the coil, then through the coil's side to the other side, and finally out through the first air outlet. This structural design provides excellent airflow concentration and dispersion, allowing airflow to pass more evenly through the coil gaps, thereby enhancing heat exchange.

[0024] Specifically: the main frame 103 is a square frame, and the front cover 101 and the rear cover 102 are both square funnel-shaped.

[0025] Specifically: the second air inlet b and the second air outlet d are both located on the main frame 103.

[0026] Referring to Figure 3, the system also includes an air inlet pipe 7, a first air outlet pipe 8, a second air outlet pipe 9, and a third air outlet pipe 10. The air inlet pipe 7 is connected to the first air inlet a; the first air outlet pipe 8 is connected to the first air outlet c; the second air outlet pipe 9 is connected to the second pipe interface via the first control valve 4; and the third air outlet pipe 10 is connected to the third pipe interface via the second control valve 5. During operation, the air inlet pipe 7 is directly connected to the outside environment, allowing outside air to enter the transition chamber 1 through the air inlet pipe 7. Both the first and second air outlet pipes 8 and 9 are connected to the interior of the vehicle, while the third air outlet pipe 10 is connected to the outside environment, allowing airflow within the transition chamber 1 to enter the vehicle interior through the first air outlet pipe 8. When the first control valve 4 is open, airflow within the coil enters the vehicle interior through the second air outlet pipe 9; when the second control valve 5 is open, airflow within the coil is directly discharged to the outside environment through the third air outlet pipe 10.

[0027] Specifically: the end of the second air outlet duct 9 furthest from the first control valve 4 is connected to the first air outlet duct 8. This allows the airflow discharged from the second air outlet duct 9 to mix with the airflow inside the first air outlet duct 8 before entering the vehicle. This ensures that the airflow discharged from the transition device 1 and the airflow discharged from the electric heater 3 are mixed before entering the vehicle, thus maintaining a relatively stable temperature of the airflow entering the vehicle. This prevents airflows of different temperatures from entering the vehicle and improves comfort.

[0028] In this embodiment, an odor detector 11 is provided between the first pipe interface and the second air outlet d; it also includes a controller, which is used to acquire the detection result of the odor detector 11 and control the first control valve 4 or the second control valve 5 to open based on the acquired odor detection result. The specific control method is as follows:

[0029] When the odor detector 11 detects an odor in the air discharged from the electric heater 3, it sends the detection result to the controller. Upon receiving the signal, the controller closes the first control valve 4 and opens the second control valve 5 to direct the airflow discharged from the electric heater 3 to the outside. This structural design allows for automatic switching of airflow direction without driver intervention.

[0030] In this embodiment, a dust detector 12 is also provided between the first pipe interface and the second air outlet d; the controller is used to acquire the detection result of the dust detector 12, and control the first control valve 4 or the second control valve 5 to enter the open state according to the acquired dust detection result. The specific control method is as follows:

[0031] When the dust detector 12 detects dust in the air discharged from the electric heater 3, the dust detector 12 sends the detection result to the controller. After receiving the signal, the controller controls the first control valve 4 to close and the second control valve 5 to open, so as to introduce the airflow discharged from the electric heater 3 into the outside.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
