Description

Technical Field

[0001] The embodiments of the present invention relate to vehicle engineering technologies, and in particular, to an exhaust gas interception heat transfer and reuse device and a hybrid vehicle. Background Art

[0002] In order to effectively save energy and reduce environmental pollution, currently, automobiles are beginning to transform from pure fuel vehicles to hybrid vehicles, thereby reducing the consumption of fossil energy. Currently, there is an engine using fossil fuel and an electric motor driven by electricity inside a hybrid electric vehicle. These two power sources work separately or together under different driving states of the vehicle (such as starting, low and medium speeds, uniform speed, acceleration, high speed, deceleration or braking, etc.), and through this combination, the least fuel consumption and exhaust emissions are achieved, so as to achieve the purpose of fuel saving and environmental protection. Only about one-third of the energy released by the combustion of existing automobile fuels can be effectively utilized, and the rest of the energy is mostly dissipated or emitted into the atmosphere in the form of gas, resulting in a great waste of energy and also bringing adverse environmental impacts. In order to further improve the energy utilization rate of hybrid vehicles while reducing the consumption of fossil energy, an interception heat transfer and reuse device capable of effectively utilizing the waste heat in the exhaust gas is needed to improve the energy utilization rate, and the heat in the exhaust gas is exchanged with the coolant and gas inside the vehicle through the interception heat transfer and reuse device to improve the energy utilization rate of the hybrid vehicle.

[0003] In the cold season, the traditional exhaust gas interception heat transfer and reuse device of a hybrid electric vehicle uses the heat energy in the exhaust gas discharged from the vehicle engine to heat the coolant inside the vehicle's water tank and the air entering the vehicle interior. After the coolant temperature rises, it flows into the electric motor driven by the battery inside the vehicle through a preset circulation pipeline inside the vehicle to heat the electric motor, thereby improving the operating environment of the electric motor in cold weather, improving the operating efficiency of the electric motor, and thus improving the warm-up efficiency of the hybrid electric vehicle in cold weather, enabling the hybrid electric vehicle to start and run faster in cold weather, and at the same time effectively utilizing the heat energy in the exhaust gas to improve the energy utilization rate. However, the traditional automobile exhaust gas interception heat transfer and reuse device is relatively large in volume, and a circulation pump is required to pump out the liquid in the water tank and perform circulating heat exchange with the high-temperature exhaust gas inside the interception heat transfer and reuse device, so the manufacturing cost and occupied space of the heat transfer and reuse device will be increased. Summary of the Invention

[0004] The present invention provides an exhaust gas interception heat transfer and reuse device and a hybrid vehicle to achieve the purpose of reducing the cost and volume of the exhaust gas interception heat transfer and reuse device. [[ID=1,8]]

[0056] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that only parts related to the present invention are shown in the drawings for the convenience of description, rather than all the structures.

[0057] Embodiment 1

[0058] Figure 1It is a structural block diagram of the waste gas intercepting heat transfer and reuse device in the embodiment. Refer to Figure 1 The waste gas intercepting heat transfer and reuse device includes:

[0059] A waste gas intercepting unit 100. In this embodiment, the waste gas intercepting unit 100 is arranged to be connected to the waste gas exhaust pipe 1, and the waste gas intercepting unit 100 is used to extract a part of (high-temperature) waste gas from the waste gas exhaust pipe 1.

[0060] Exemplarily, in this embodiment, the manner in which the waste gas intercepting unit 100 extracts waste gas from the waste gas exhaust pipe 1 is not limited. For example, the waste gas intercepting unit 100 can be configured to actively extract waste gas from the waste gas exhaust pipe 1, or the pressure of the waste gas exhaust pipe 1 can be used to make the waste gas enter the waste gas intercepting unit 100 by itself.

[0061] It further includes a first heat exchange box 201, a first liquid storage tank 202, and a first heat exchange circulation pipeline 203.

[0062] In this embodiment, the first heat exchange box 201 is configured with a first controllable air inlet 2011 and a first controllable air outlet 2012, and the waste gas intercepting unit 100 is connected to the first heat exchange box 201 through the first controllable air inlet 2011.

[0063] In this embodiment, the first heat exchange box 201 is used to store the waste gas input by the waste gas intercepting unit 100 into the first heat exchange box 201. Specifically, when the first controllable air inlet 2011 is controlled to be opened, the waste gas can enter the first heat exchange box 201 from the waste gas intercepting unit 100;

[0064] In this embodiment, when the first controllable air outlet 2012 is controlled to be opened, the waste gas can be discharged from the first heat exchange box 201.

[0065] In this embodiment, the first liquid storage tank 202 is configured with a first controllable liquid inlet 2021 and a first controllable liquid outlet 2022. The two ends of the first heat exchange circulation pipeline 203 are respectively connected to the first controllable liquid inlet 2021 and the first controllable liquid outlet 2022, and the main body of the first heat exchange circulation pipeline 203 surrounds the outer wall of the first heat exchange box 201.

[0066] Exemplarily, in this embodiment, the first liquid storage tank 202 stores coolant. When the first controllable liquid inlet 2021 is controlled to be opened, the coolant in the first liquid storage tank 202 can enter the first heat exchange circulation pipeline 203;

[0067] When the first controllable liquid outlet 202 is controlled to be opened, the coolant in the first heat exchange circulation pipeline 203 can flow back into the first liquid storage tank 202.

[0068] Exemplarily, in this solution, when there is coolant in the first heat circulation pipeline 203 and there is high-temperature waste gas in the first heat exchange box 201, the coolant can exchange heat with the high-temperature waste gas, thereby increasing the temperature of the coolant;

[0069] After the coolant and the high-temperature waste gas complete the heat exchange process, the waste gas in the first heat exchange box 201 can be discharged.

[0070] In this embodiment, a first plate is arranged in the first heat exchange box 201, a second plate is arranged in the first liquid storage tank 202, and the first plate is connected to the second plate through a first connecting rod;

[0071] The first connecting rod passes through the outer walls of the first heat exchange box 201 and the first liquid storage tank 202 and is slidably and sealingly connected to the first heat exchange box 201 and the first liquid storage tank 202.

[0072] Exemplarily, in this embodiment, when it is set to transport waste gas from the waste gas interface unit 100 into the first heat exchange box 201, the first controllable air inlet 2011 is controlled to open, the first controllable exhaust port 2012 is closed, the first controllable liquid inlet 2021 is controlled to open, and the first controllable liquid outlet 2022 is closed;

[0073] At this time, when the waste gas enters the first heat exchange box 201, the pressure in the first heat exchange box 201 increases, the first plate moves, and correspondingly, the movement of the first plate drives the movement of the second plate;

[0074] When the second plate moves, the pressure in the first liquid storage tank 202 changes, causing the cooler in the first liquid storage tank 202 to enter the first heat exchange circulation pipeline 203 by itself under the action of pressure.

[0075] It further includes a second heat exchange box 204, a second liquid storage tank 205, and a second heat exchange circulation pipeline 206.

[0076] The second heat exchange box 204 is provided with a second controllable air inlet 2041 and a second controllable exhaust port 2042, and the waste gas interception unit 100 is connected to the second heat exchange box 204 through the second controllable air inlet 2041.

[0077] In this embodiment, the second heat exchange box 204 is used to store the waste gas input by the waste gas interception unit 100 into the second heat exchange box 204. Specifically, when the second controllable air inlet 2041 is controlled to open, the waste gas can enter the second heat exchange box 204 from the waste gas interception unit 100;

[0078] In this embodiment, when the second controllable exhaust port 2042 is controlled to open, the waste gas can be discharged from the second heat exchange box 204.

[0079] The second liquid storage tank 205 is provided with a second controllable liquid inlet 2051 and a second controllable liquid outlet 2052. The two ends of the second heat exchange circulation pipeline 206 are respectively connected to the second controllable liquid inlet 2051 and the second controllable liquid outlet 2052, and the main body of the second heat exchange circulation pipeline 206 surrounds the outer wall of the second heat exchange tank 204.

[0080] Exemplarily, in this embodiment, the second liquid storage tank 205 stores coolant. When the second controllable liquid inlet 2051 is controlled to open, the coolant in the second liquid storage tank 205 can enter the second heat exchange circulation pipeline 206.

[0081] When the second controllable liquid outlet 2052 is controlled to open, the coolant in the second heat exchange circulation pipeline 206 can flow back into the second liquid storage tank 205.

[0082] Exemplarily, in this solution, when there is coolant in the second heat exchange circulation pipeline 206 and there is high-temperature waste gas in the second heat exchange tank 204, the coolant can exchange heat with the high-temperature waste gas, thereby increasing the temperature of the coolant.

[0083] After the coolant completes the heat exchange process with the high-temperature waste gas, the waste gas in the second heat exchange tank 204 can be discharged.

[0084] A third plate is arranged in the second heat exchange tank 204, and a fourth plate is arranged in the second liquid storage tank 205. The third plate is connected to the fourth plate through a second connecting rod.

[0085] The second connecting rod passes through the outer walls of the second heat exchange tank 204 and the second liquid storage tank 205 and is slidably and sealingly connected to the second heat exchange tank 204 and the second liquid storage tank 205.

[0086] Exemplarily, in this embodiment, when it is set to transport waste gas from the waste gas interface unit 100 into the second heat exchange tank 204, the second controllable air inlet 2041 is controlled to open, the second controllable exhaust port 2042 is closed, the second controllable liquid inlet 2051 is controlled to open, and the second controllable liquid outlet 2052 is closed.

[0087] At this time, when the waste gas enters the second heat exchange tank 204, the pressure in the second heat exchange tank 204 increases, the third plate moves, and correspondingly, the movement of the third plate drives the fourth plate to move.

[0088] When the fourth plate moves, the pressure in the second liquid storage tank 205 changes, causing the cooler in the second liquid storage tank 205 to enter the second heat exchange circulation pipeline 206 by itself under the action of the pressure.

[0089] It further includes a gear transmission unit 300.

[0090] The gear transmission unit 300 is respectively connected to the second plate and the fourth plate. When the second plate moves, the gear transmission unit is used to make the fourth plate move in the direction opposite to the movement direction of the second plate.

[0091] In this embodiment, the gear transmission unit 300 is set as a mechanical component. When the second plate moves based on the mechanical structure, the fourth plate is made to move in the direction opposite to the movement direction of the second plate.

[0092] In this embodiment, the specific structure of the gear transmission unit 300 is not limited. The gear transmission unit 300 may include a gear set. Specifically, when the second plate moves, the fourth plate is made to move in the direction opposite to the movement direction of the second plate through the gear set.

[0093] In this embodiment, the purpose of setting the gear transmission unit 300 to make the fourth plate move in the direction opposite to the movement direction of the second plate when the second plate moves is as follows:

[0094] Without the aid of an additional water pump, the coolant in a liquid storage tank can enter the heat exchange circulation pipeline from the liquid storage tank by itself, and then flow back to the liquid storage tank from the heat exchange circulation pipeline by itself, thereby realizing the circulation of the coolant;

[0095] For example, when the first controllable air inlet 2011 is controlled to open, the second controllable exhaust port 2012 is controlled to close, the first controllable liquid inlet 2021 is controlled to open, and the first controllable liquid outlet 2022 is controlled to close, when the first plate (second plate) runs to the maximum stroke position, the first heat exchange circulation pipeline 203 is filled with the coolant entering from the first liquid storage tank 202. At this time, the coolant in the first heat exchange circulation pipeline 203 exchanges heat with the exhaust gas in the first heat exchange box 201;

[0096] When the first controllable air inlet 2011 is controlled to open, the second controllable exhaust port 2012 is controlled to close, the first controllable liquid inlet 2021 is controlled to open, and the first controllable liquid outlet 2022 is controlled to close, the second controllable air inlet 2041 is controlled to close, the second controllable exhaust port 2042 is controlled to open, the second controllable liquid inlet 2051 is controlled to close, and the second controllable liquid outlet 2052 is controlled to open;

[0097] Correspondingly, when the first plate runs to the maximum stroke position, the third plate (fourth plate) runs to the minimum stroke position, all the cold in the second heat exchange circulation pipeline 206 flows back to the second liquid storage tank 205, and there is no exhaust gas in the second heat exchange box 204;

[0098] During the process of the first plate running to the minimum stroke position and the third plate correspondingly running to the maximum stroke position, the control / working mode of each part is opposite to the above process, and the specific content will not be elaborated here.

[0099] It also includes a controller (not shown in the figure);

[0100] The controller is respectively connected to a first controllable air inlet 2011, a first controllable air outlet 2012, a first controllable liquid inlet 2021, a first controllable liquid outlet 2022, a second controllable air inlet 2041, a second controllable air outlet 2042, a second controllable liquid inlet 2051, a second controllable liquid outlet 2052, and a gear transmission unit 300.

[0101] Exemplarily, in this embodiment, the software control method configured in the controller is not specifically limited. For example, the controller can be configured to specifically:

[0102] Obtain the operating position of the gear transmission unit 300, and determine whether the second plate (or the fourth plate) reaches the maximum / minimum stroke position according to the gear transmission unit 300;

[0103] When the second plate reaches the maximum stroke position, control the first controllable air inlet 2011 to close, the second controllable air outlet 2012 to open, the first controllable liquid inlet 2021 to close, and the first controllable liquid outlet 2022 to open;

[0104] Control the second controllable air inlet 2041 to open, the second controllable air outlet 2042 to close, the second controllable liquid inlet 2051 to open, and the second controllable liquid outlet 2052 to close;

[0105] When the second plate reaches the minimum stroke position, control the first controllable air inlet 2011 to open, the second controllable air outlet 2012 to close, the first controllable liquid inlet 2021 to open, and the first controllable liquid outlet 2022 to close;

[0106] Control the second controllable air inlet 2041 to close, the second controllable air outlet 2042 to open, the second controllable liquid inlet 2051 to close, and the second controllable liquid outlet 2052 to open.

[0107] This embodiment provides an exhaust gas interception heat transfer and reuse device. By continuously switching the first controllable air inlet, the second controllable air inlet, the first controllable air outlet, the second controllable air outlet, the first controllable liquid inlet, the second controllable liquid inlet, the first controllable liquid outlet, and the second controllable liquid outlet between opening and closing according to a rule, the coolant inside the liquid storage tank can continuously circulate and exchange heat with the corresponding heat exchange tank through the corresponding heat exchange circulation pipeline;

[0108] In addition, based on the gear transmission unit, the device can move the plate inside the liquid storage tank back and forth in the liquid storage tank in the reverse direction without using a circulation pump, thereby providing stable power for the circulation of the coolant inside the liquid storage tank, improving the working efficiency of the exhaust gas interception heat transfer and reuse device, saving the manufacturing cost, and reducing the overall space required for the device at the same time.

[0109] Figure 2 It is the structural block diagram of the exhaust gas interception unit in the embodiment. Refer toFigure 2 , on the basis of the solution shown in Figure 1 , the exhaust gas interception unit includes: an air guide box 101, an air pump 102, and an exhaust gas extraction valve 103;

[0110] The air guide box 101 is respectively connected to the first controllable air inlet 2011, the second controllable air inlet 2041, and the air pump 102. The air pump 102 is also connected to the exhaust gas pipe 1 through the exhaust gas extraction valve 103. The controller is also respectively connected to the air pump 102 and the exhaust gas extraction valve 103.

[0111] In this solution, the air guide box 101 is used for temporarily storing the exhaust gas extracted from the exhaust gas pipe 1 to ensure that the exhaust gas can stably enter the first heat exchange box 201 and the second heat exchange box 204.

[0112] In this solution, by controlling the air pump 102 and the exhaust gas extraction valve 103, it is possible to stop or start extracting exhaust gas from the exhaust gas pipe 1;

[0113] Specifically, when the air pump 102 works and the exhaust gas extraction valve 103 is opened, the air pump 102 extracts exhaust gas from the exhaust gas pipe 1. Then, when the first controllable air inlet 2011 or the second controllable air inlet 2041 is controlled to open, the exhaust gas can enter the corresponding heat exchange box;

[0114] When the air pump 102 stops working and / or the exhaust gas extraction valve 103 is closed, the air pump 102 no longer extracts exhaust gas from the exhaust gas pipe 1. At this time, the exhaust gas interception heat transfer reuse device temporarily does not have the heat exchange function.

[0115] Figure 3 is the structural block diagram of another exhaust gas interception heat transfer reuse device in the embodiment. Refer to Figure 3 , on the basis of the solution shown in Figure 2 , the exhaust gas interception heat transfer reuse device further includes an electronically controlled suction valve 104 and an air duct 105;

[0116] The electronically controlled suction valve 104 is connected to the air duct 105, and the air duct 105 is also connected to the air pump 102.

[0117] Exemplarily, in this solution, the electronically controlled suction valve 104 is installed on the vehicle body surface, and the air duct 105 is used to connect the electronically controlled suction valve 104 and the air pump 102.

[0118] In this solution, it is set that either the electronically controlled air intake valve 104 or the exhaust gas extraction valve 103 is opened. When it is set that the electronically controlled air intake valve 104 is opened and the air pump 102 is operating, the air pump 102 extracts air from the environment through the electronically controlled air intake valve 104. At this time, the air replaces the exhaust gas extracted when the exhaust gas extraction valve 103 is opened and enters the air guide box 101. After the air enters the first heat exchange box 201 or the second heat exchange box 204, it exchanges heat with the coolant in the corresponding heat exchange circulation pipeline.

[0119] Specifically, when the vehicle is running, a large airflow will be formed on the surface. These airflows will enter the interior of the air guide pipe 105 through the electronically controlled air intake valve 104. Under the suction of the air pump 102, the air will enter the air guide box 101 and then enter the first heat exchange box 201 or the second heat exchange box 204.

[0120] In hot weather, the coolant inside the liquid storage tank has already reached a very high temperature after exchanging heat with the equipment inside the vehicle. The temperature of the motor driven by the battery inside the vehicle will also be very high during operation. At this time, there is no need to heat the coolant by exchanging heat with the high-temperature exhaust gas anymore.

[0121] In this solution, an electronically controlled air intake valve is configured for the exhaust gas interception heat transfer and reuse device. When the weather is hot, ambient air is used to replace the high-temperature exhaust gas to exchange heat with the coolant in the liquid storage tank, which increases the functionality of the exhaust gas interception heat transfer and reuse device and improves the flexibility of use of the exhaust gas interception heat transfer and reuse device.

[0122] In this solution, in hot weather, when the temperature of the coolant inside the liquid storage tank reaches the specified temperature, the controller will control the exhaust gas extraction valve to close and simultaneously open the electronically controlled air intake valve. The external natural wind will enter the interior of the air guide pipe through the electronically controlled air intake valve and enter the heat exchange box under the suction of the air pump, replacing the previous high-temperature exhaust gas. At this time, the relatively high-temperature coolant inside the liquid storage tank will transfer heat to the relatively low-temperature natural wind inside the heat exchange box through the heat exchange circulation pipeline, thereby reducing the temperature of the coolant inside the liquid storage tank and enabling the coolant inside the liquid storage tank to better exchange heat and cool down the engine and the motor, improving the operation effect of the hybrid electric vehicle in hot weather.

[0123] Figure 4 It is another structural block diagram of the exhaust gas interception heat transfer and reuse device in the embodiment. Refer to Figure 4 , on the basis of the solution shown in Figure 2 , the exhaust gas interception heat transfer and reuse device further includes a porous connecting pipe 106;

[0124] The porous connecting pipe 106 is respectively connected to the first controllable exhaust port 2012, the second controllable exhaust port 2042, and the exhaust gas discharge pipe 1.

[0125] In this solution, the porous connecting pipe 106 is used for guiding the exhaust gas discharged from the first controllable exhaust port 2012, the second controllable exhaust port 2042, and / or the porous connecting pipe 106, thereby standardizing the layout of the exhaust gas discharge pipeline part of the exhaust gas interception heat transfer and reuse device.

[0126] Based on the Figure 1 solution shown, in an implementable solution, the gear transmission unit includes: an L-shaped mounting plate, a first movable plate, a second movable plate, and a gear assembly;

[0127] The gear assembly is fixedly connected to the outer wall of the first liquid storage tank 202 and / or the second liquid storage tank 205 through the L-shaped mounting plate;

[0128] The first movable plate is fixedly connected to the second plate, and the second movable plate is fixedly connected to the fourth plate;

[0129] The first movable plate and the second movable plate are respectively provided with racks, and the first movable plate and the second movable plate are respectively connected to the gear assembly through the racks;

[0130] When the gear assembly is used for the movement of the second plate, the fourth plate moves in the direction opposite to the movement direction of the second plate.

[0131] Exemplarily, in this solution, the rack is used to mesh with the gear in the gear assembly, and it is set that the length of the rack is shorter than that of the movable plate by a certain length;

[0132] Taking the second plate as an example, when the second plate leans against one side of the first liquid storage tank 202, that is, in the minimum stroke position, the length of the first movable plate protruding from one side of the first liquid storage tank 202 is the maximum length;

[0133] Since the rack provided on the first movable plate does not cover the entire first movable plate, at this time, the rack on one side of the first movable plate cannot contact the gear at the bottom of the L-shaped mounting plate;

[0134] When the first movable plate on one side of the first liquid storage tank 202 moves forward first following the second plate, the second movable plate on one side of the second liquid storage tank 205 will not be affected by the gear rotating at the bottom of the L-shaped mounting plate;

[0135] When the second plate inside the first liquid storage tank 202 is pushed by the first plate to move to the front end of the first liquid storage tank 202, the second plate has been pushed forward the maximum distance, that is, in the maximum stroke position;

[0136] At this time, when the fourth plate inside the first liquid storage tank 202 moves under the push of the third plate (the initial position of the third plate is the minimum stroke position), the second movable plate moves forward with the fourth plate;

[0137] The rack provided on the second movable plate drives the first movable plate to move in the opposite direction through the gear at the bottom of the L-shaped mounting plate, thereby driving the second plate and the first plate to reset, thus completing a cycle process in which the coolant enters the first heat exchange circulation pipeline 203 and then returns to the first liquid storage tank 202 from the first heat exchange circulation pipeline 203;

[0138] In this solution, under the action of the gear assembly, the first movable plate and the second movable plate can alternately move to their respective maximum stroke positions and minimum stroke positions, and then can drive the plates in the corresponding liquid storage tank to move back and forth cyclically, so as to realize that without an additional water pump, the coolant in the corresponding liquid storage tank can enter the heat exchange circulation pipeline cyclically and be discharged from the heat exchange circulation pipeline, and the cycle completes the heat exchange process between the coolant and the waste gas.

[0139] When the gear transmission unit includes an L-shaped mounting plate, a first movable plate, a second movable plate and a gear assembly, in an implementable solution, the gear transmission unit further includes a first collision switch and a second collision switch;

[0140] The first collision switch is arranged in the first heat exchange box, and the first collision switch is used to determine whether the first plate moves in place;

[0141] The second collision switch is arranged in the second heat exchange box, and the second collision switch is used to determine whether the third plate moves in place;

[0142] The first collision switch and the second collision switch are also connected to the controller, and the controller is configured to control the actions of a controllable air inlet, a first controllable exhaust port, a first controllable liquid inlet, a first controllable liquid outlet, a second controllable air inlet, a second controllable exhaust port, a second controllable liquid inlet and a second controllable liquid outlet according to the signals of the first collision switch and the second collision switch.

[0143] Exemplarily, in this solution, the first collision switch is used to determine whether the first plate moves to the maximum stroke position, and the second collision switch is used to determine whether the second plate moves to the maximum stroke position.

[0144] Exemplarily, in this solution, when the first plate touches the first collision switch, the first plate moves to the maximum stroke position, and the first collision switch outputs a first signal. At this time, control the first controllable air inlet 2011 to close, the second controllable exhaust port 2012 to open, the first controllable liquid inlet 202 to close, and the first controllable liquid outlet 2022 to open;

[0145] Control the second controllable air inlet 2041 to open, the second controllable exhaust port 2042 to close, the second controllable liquid inlet 2051 to open, and the second controllable liquid outlet 2052 to close;

[0146] When the third plate touches the second collision switch, the third plate moves to the maximum stroke position, and the second collision switch outputs a second signal. At this time, control the first controllable air inlet 2011 to open, the second controllable air outlet 2012 to close, the first controllable liquid inlet 2021 to open, and the first controllable liquid outlet 2022 to close;

[0147] Control the second controllable air inlet 2041 to close, the second controllable air outlet 2042 to open, the second controllable liquid inlet 2051 to close, and the second controllable liquid outlet 2052 to open.

[0149] A second liquid collecting tank is further provided in the second liquid storage tank 205, and the second controllable liquid outlet 2052 is provided at the second liquid collecting tank.

[0150] In this scheme, the liquid collecting tank is used to guide and gather the liquid inside the liquid storage tank, so that the liquid inside the liquid storage tank can quickly enter the controllable liquid inlet through the liquid collecting tank when being squeezed by the plate, thereby appropriately reducing the resistance suffered by the plate when moving forward and improving the stability of the plate when moving forward.

[0151] In Figure 1 Based on the scheme shown, in an implementable scheme, a first guiding frame is further provided inside the first liquid storage tank 202, and the first guiding frame is used for guiding the first connecting rod;

[0152] A second guiding frame is further provided in the second liquid storage tank 205, and the second guiding frame is used for guiding the second connecting rod.

[0153] Exemplarily, in this scheme, the guiding frame is provided to keep the connecting rod running stably in a fixed direction when moving.

[0154] In Figure 1 Based on the scheme shown, in an implementable scheme, the first liquid storage tank and the second liquid storage tank are connected by a sealing partition board, and a diversion hole is provided on the sealing partition board, and the diversion hole is used to connect the first liquid storage tank and the second liquid storage tank;

[0155] A liquid filling port and a liquid discharging port are further provided on the first liquid storage tank and / or the second liquid storage tank.

[0156] Exemplarily, in this scheme, the diversion hole connects the first liquid storage tank and the second liquid storage tank, and the staff only needs to fill the inside of the first liquid storage tank 202 and the second liquid storage tank 205 with coolant through one liquid filling port;

[0157] Meanwhile, connect the liquid drain port to one end of the main liquid outlet pipeline, and the coolant inside the liquid storage tank can be sent into the engine and the motor inside the hybrid vehicle through this main liquid outlet pipe, so as to carry out circulating heat dissipation or heating work.

A second guiding frame is further arranged inside the second liquid storage tank 205, and the second connecting rod passes through the second guiding frame;

[0174] The gear assembly is fixedly connected to the outer wall of the first liquid storage tank 202 and / or the second liquid storage tank 205 through the L-shaped mounting plate 601;

[0175] The first movable plate 602 is fixedly connected to the second plate 2023, and the second movable plate 603 is fixedly connected to the fourth plate 2053;

[0176] The first movable plate 602 and the second movable plate 603 are respectively provided with racks, and the first movable plate 602 and the second movable plate 603 are respectively connected to the gear assembly through the racks;

[0177] The gear transmission unit further includes a first collision switch and a second collision switch;

[0178] The first collision switch is arranged in the first heat exchange tank, and the first collision switch is used to determine whether the first plate moves in place;

[0179] The second collision switch is arranged inside the second heat exchange tank, and the second collision switch is used to determine whether the third plate has moved in place;

[0180] A first liquid collecting tank 801 is further arranged inside the first liquid storage tank 202, and the first controllable liquid outlet 2022 and the first controllable liquid inlet 2021 are arranged at the first liquid collecting tank;

[0181] A second liquid collecting tank 802 is further arranged inside the second liquid storage tank 205, and the second controllable liquid outlet 2052 and the second controllable liquid inlet 2051 are arranged at the second liquid collecting tank;

[0182] The first liquid storage tank and the second liquid storage tank are connected through a sealing partition plate 700, and a diversion hole 702 and a temperature sensor 703 are arranged on the sealing partition plate 700. The diversion hole 702 is used to connect the first liquid storage tank 202 and the second liquid storage tank 205;

[0183] A liquid filling port 500 and a liquid discharge port 701 are further arranged on the first liquid storage tank and / or the second liquid storage tank;

[0184] It further includes a controller 400, and the controller 400 is arranged on the surface of the air guide box 101;

[0185] The controller 400 is connected to the first controllable air inlet 2011, the first controllable air outlet 2012, the first controllable liquid inlet 2021, the first controllable liquid outlet 2022, the second controllable air inlet 2041, the second controllable air outlet 2042, the second controllable liquid inlet 2051, and the second controllable liquid outlet 2052;

[0186] The controller 400 is further connected to the air pump 102, the waste gas extraction valve 103, the electronically controlled suction valve 104, the first collision switch, and the second collision switch.

[0187] Exemplarily, in this solution, the use and working mode of the waste gas interception heat transfer and reuse device include:

[0188] The controller 400 controls the waste gas extraction valve 103 to open and the air pump 102 to operate. The air pump 102 will suck the high-temperature waste gas discharged through the waste gas exhaust pipe 1 into the interior of the air guide box 101 through the waste gas extraction valve 103;

[0189] The temperature sensor 703 monitors the liquid temperature inside the liquid storage tank in real time. In hot weather, when the liquid temperature inside the liquid storage tank reaches the specified temperature, the controller 400 will control the waste gas extraction valve 103 to close, so that the high-temperature waste gas inside the waste gas exhaust pipe 1 directly enters the porous connecting pipe 106 and then is discharged;

[0190] Meanwhile, the controller 400 opens the electronically controlled suction valve 104, and air enters the inside of the air guide pipe 105 through the electronically controlled suction valve 104. The air pump 102 sucks the air inside the air guide pipe 105 into the inside of the air guide box 101, thereby replacing the previous high-temperature waste gas (which exchanges heat with the coolant in the heat exchange circulation pipeline);

[0191] The diversion hole 702 connects the first liquid storage tank 202 and the second liquid storage tank 205, and the staff can fill the inside of the liquid storage tank with liquid only through one liquid filling port 500;

[0192] The liquid filling port 500 is arranged at the top of the first liquid storage tank 202 and above the first liquid collecting tank 801. When the staff adds liquid into the first liquid storage tank 202 through the liquid filling port 500, first, the controller 400 controls the first controllable exhaust port 2012 and the second controllable exhaust port 2042 to open, so that the gas inside the first heat exchange box 201 and the second heat exchange box 204 can be discharged to the outside through the first controllable exhaust port 2012 and the second controllable exhaust port 2042 respectively;

[0193] During the process of filling the coolant into the first liquid storage tank 202 through the liquid filling port 500, the first movable plate 602 and the second movable plate 603 are successively pulled, so that the second plate and the fourth plate on both sides of the sealing partition 700 are respectively closely attached to the inner wall of one side of the water tank 2, thereby successfully filling the liquid storage tank;

[0194] The liquid discharge port 701 is connected to one end of the main liquid discharge pipeline, and the coolant inside the liquid storage tank can be sent into the engine and the motor inside the hybrid vehicle through the liquid discharge port 701 for circulating heat dissipation or heating work, so as to ensure that only one liquid filling port 500 and one liquid discharge port 701 of the two liquid storage tanks can stably supply coolant to the outside.

[0195] When the piston plate 24 moves to one side of the guide frame 33 under the push of the gas, it will collide with the collision switch 32 on one side of the guide frame 33. At this time, the collision switch 32 will send an electrical signal to the controller 400, so that the controller 400 controls the corresponding first controllable intake port 2011, second controllable intake port 2041, first electronically controlled water suction valve 20, second controllable liquid outlet 2052, first electronically controlled drain valve 29 and second controllable liquid inlet 2051 to close, improving the accuracy during the operation of the device.

[0196] In this solution, the heat exchange circulation process includes:

[0197] The controller 400 first controls the first controllable intake port 2011 to close and the second controllable intake port 2041 to open. When the first controllable intake port 2011 is closed, all the waste gas inside the air guide box 101 is filled into the second heat exchange box 204 through the second controllable intake port 2041;

[0198] The controller 400 controls the second controllable liquid outlet 2052 to close and the second controllable liquid inlet 2051 to open. The third plate moves forward under the push of gas pressure, thereby pushing the fourth plate 2053 forward through the second connecting rod, allowing the coolant in the second liquid storage tank 205 to enter the second heat exchange circulation pipeline 206 through the second controllable liquid inlet 2051;

[0199] The coolant in the second heat exchange circulation pipeline 206 exchanges heat with the superheated exhaust gas filled inside the second heat exchange tank 204, thereby increasing the temperature of the coolant stored inside the liquid storage tank. In cold weather, it ensures that the coolant inside the liquid storage tank always remains at a relatively high temperature, improving the vehicle's warm-up efficiency;

[0200] When the third plate inside the second heat exchange tank 204 moves to collide with the second collision switch under the push of the exhaust gas, it indicates that the fourth plate 2053 has been pushed forward the maximum distance;

[0201] At this time, the controller 400 controls the second controllable air inlet 2041 to close and opens the first controllable air inlet 2011. The pressurized gas inside the air guide box 101 will enter the first heat exchange tank 201 through the first controllable air inlet 2011;

[0202] The controller 400 controls the second controllable liquid inlet 2051 and the first electric control water suction valve 20 to close, and the first electric control drain valve 29 and the second controllable liquid outlet 2052 to open;

[0203] When the first plate 2013 inside the first heat exchange tank 201 moves forward under the action of gas thrust, the second plate 2023 allows the coolant in the first liquid storage tank 202 to enter the first heat exchange circulation pipeline 203 through the first controllable liquid inlet 2021;

[0204] When the second plate 2023 moves, the gear assembly at the bottom of the L-shaped mounting plate 601 drives the fourth plate 2053 to move in the opposite direction, resetting the fourth plate 2053. During the resetting process of the fourth plate 2053, the negative pressure in the second liquid storage tank 205 sucks the second heat exchange circulation pipeline 206 back into the second liquid storage tank 205, thus completing a cycle in which the coolant enters the second heat exchange circulation pipeline 206 and then returns to the inside of the second liquid storage tank 205;

[0205] When the fourth plate 2053 resets, the controller 400 will simultaneously control the second controllable exhaust port 2042 to open. The exhaust gas after heat exchange inside the second heat exchange tank 204 is sent to the exhaust gas emission mechanism through the second controllable exhaust port 2042 and then discharged outside the device.

[0206] When the second plate 2023 and the fourth plate 2053 run alternately back and forth, it is possible to achieve the circulation heat exchange between the coolant inside the first liquid storage tank 202 and the waste gas (or air) inside the first heat exchange tank 201, and between the coolant inside the second liquid storage tank 205 and the waste gas (or air) inside the second heat exchange tank 204 without using a circulation pump.

[0207] Exemplarily, in this solution, the relative lengths between the connecting rod, the liquid storage tank, and the heat exchange tank can be determined in the following manner:

[0208] Taking the second connecting rod as an example, when the fourth plate 2053 moves forward to the maximum position, the fourth plate 2053 moves forward by a distance of about two-thirds of the length of the second liquid storage tank 205, and the bottom of the fourth plate 2053 just abuts against the edge of the second liquid collecting tank 802 (close to the second heat exchange tank 204);

[0209] If the fourth plate 2053 moves to the top of the second liquid collecting tank 802, the coolant is likely to flow back into the second liquid storage tank 205 in large quantities through the gap between the second liquid collecting tank 802 and the fourth plate 2053, on the other side of the fourth plate 2053, resulting in the destruction of the water circulation flow between the second liquid storage tank 205 and the second heat exchange circulation pipeline 206, and causing the entire heat transfer and reuse device to malfunction.

[0210] Exemplarily, in this solution, the setting plate slides and is hermetically connected to the four - week inner wall of the liquid storage tank. By doing so, when the plate pushes the coolant, it is very difficult for the coolant to seep into the liquid storage tank, on the other side of the plate, thus effectively avoiding the leakage of the coolant inside the liquid storage tank through the connection part between the guiding frame and the movable plate and the liquid storage tank, and improving the overall sealing performance of the device.
