[0002] The radiator is a crucial component in the engine's cooling cycle. Engines generate a significant amount of heat during operation; if this heat cannot be dissipated effectively, it can lead to overheating and damage to internal parts. The coolant in the radiator circulates through the engine's cooling channels, absorbing and carrying away the heat generated by the engine, thus ensuring that the engine operates within its normal temperature range.

[0003] However, the water in the water tank is prone to freezing in extremely cold weather. Existing technology usually uses an additional electric heating device to defrost the water tank. However, the electric heating device consumes a lot of electricity when used for a long time or when defrosting frequently, which increases the vehicle's energy consumption and results in high operating costs.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is understood that the present application may be implemented in various forms and should not be limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art. It should also be noted that, for ease of description, only the parts relevant to the present application are shown in the accompanying drawings.

[0035] It should be noted that, where there is no conflict, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Embodiments of this application provide a heat dissipation device and a vehicle.

[0037] Vehicles can be gasoline, diesel, or hybrid. The engine is the heart of the vehicle, providing power for its operation. When the engine runs, it generates a significant amount of heat. If this heat is not dissipated promptly, the engine will overheat, affecting its normal operation and lifespan. Vehicles are equipped with a cooling system (usually a radiator), which stores a cooling medium. Through the circulation of this medium, the heat generated by the engine is carried away, maintaining the engine within a suitable temperature range. In extremely cold weather, current technology typically uses an electric heater inside the radiator to prevent the cooling medium from freezing or to defrost it. However, this method consumes a large amount of electricity, increasing vehicle energy consumption and operating costs. Furthermore, improper temperature control or excessive heating time of the electric heater can cause deformation, aging, or even cracking of the internal materials of the radiator, damaging the radiator and affecting the engine's normal operation.

[0038] In view of this, a first aspect of this application provides a heat dissipation device, including a housing 10 and a heat exchanger 20. The housing 10 is used to contain a cooling medium 11. The heat exchanger 20 is disposed inside the housing 10. An airflow channel 40 is provided inside the heat exchanger 20. The airflow channel 40 is used to supply exhaust gas from the engine. The exhaust gas can exchange heat with the cooling medium 11 inside the housing 10 through the heat exchanger 20.

[0039] The exhaust gas can exchange heat with the cooling medium 11 inside the housing 10 through the heat exchanger 20. This can be achieved by directly setting the wall of the airflow channel 40 inside the housing 10 and contacting the cooling medium 11 for heat exchange, or by setting a cooling medium channel 50 in the heat exchanger 20 to allow the cooling medium 11 inside the housing 10 to enter and contact the wall of the airflow channel 40 in the heat exchanger 20 for heat exchange.

[0040] This application provides a heat exchanger 20 inside a housing 10 containing cooling medium 11, and an airflow channel 40 inside the heat exchanger 20 for the flow of engine exhaust gas. This allows the engine exhaust gas to exchange heat with the cooling medium 11 inside the housing 10. Thus, when extremely cold weather occurs, there is no need to install an additional electric heating device. The heat in the engine exhaust gas can be transferred to the cooling medium 11 through the heat exchanger 20, thereby preventing the cooling medium 11 from freezing or de-icing it after it has frozen. This saves vehicle energy consumption and reduces operating costs.

[0041] As an feasible approach, such as Figures 1-3 As shown, the heat exchanger 20 includes a heat exchange tube wall 21, and an airflow channel 40 is formed inside the heat exchange tube wall 21. The exhaust gas of the engine enters the heat exchange tube wall 21 through the airflow channel 40. The outside of the heat exchange tube wall 21 is in contact with the cooling medium 11 inside the housing 10. The heat in the engine exhaust gas is transferred to the cooling medium 11 through the heat exchange tube wall 21, thereby realizing heat exchange.

[0042] As one feasible approach, the heat dissipation device also includes a water collection component 30 disposed within the housing 10. The water collection component 30 has a water collection chamber 31 internally, which is connected to the airflow channel 40 to receive condensate adhering to the inner wall of the airflow channel 40. Figure 2 As shown, the water collection element 30 is located at the lower part of the heat exchange tube wall 21. The airflow channel 40 inside the heat exchange tube wall 21 carries the engine exhaust gas at a higher temperature, while the outside of the heat exchange tube wall 21 carries the cooling medium 11 at a lower temperature. During heat exchange, condensate forms on the inner wall of the airflow channel 40, which is at a higher temperature. The condensate drips downwards under the influence of gravity and is collected in the water collection chamber 31, which is connected to the airflow channel 40, and participates in the new cooling cycle. Preferably, the heat exchanger 20 and the water collection element 30 are integrated into one structure, that is, they are installed inside the housing 10 as a water vapor separator. This water vapor separator can separate the water vapor in the engine exhaust gas from the gas through condensation while achieving heat exchange with the cooling medium 11 inside the housing 10.

[0043] As one feasible approach, the heat exchange tube wall 21 is spiral and extends radially from the outside to the inside, the airflow channel 40 extends along the heat exchange tube wall 21 and is spiral, and the heat exchanger 20 is also provided with a cooling medium channel 50 for the cooling medium 11 to flow through. The cooling medium channel 50 is spiral and is formed between multiple layers of heat exchange tube walls 21 arranged radially in sequence.

[0044] The radial direction of the heat exchanger tube wall 21 refers to the direction perpendicular to the central axis of the heat exchanger tube wall 21, such as... Figure 2As shown, the heat exchange tube wall 21 extends spirally from the outside to the inside, thus forming a radially multi-layered heat exchange tube wall 21. Gaps are formed between adjacent layers of heat exchange tube wall 21, and these gaps are sequentially connected, forming a spiral channel. This configuration allows the heat exchange tube wall 21 to form a "double spiral channel." The first spiral channel is an airflow spiral channel extending spirally along the heat exchange tube wall 21, used for the flow of engine exhaust gas. The second spiral channel is a cooling medium channel 50 formed between the multiple layers of heat exchange tube walls 21, allowing the cooling medium 11 to enter. The airflow channel 40 exchanges heat with the cooling medium 11 through the wall surface of the heat exchange tube wall 21, transferring the heat from the engine exhaust gas to the cooling medium 11 inside the housing 10.

[0045] The spiral design allows the heat exchange tube wall 21 to coil more times within a limited space, significantly increasing the heat exchange area. It also lengthens the fluid flow path within the tube, thus extending the fluid's residence time and facilitating more efficient heat exchange. When the exhaust gas enters the separator, guided by the spiral heat exchange tube wall 21, it is forced to generate a high-speed rotating cyclone. Water vapor in the exhaust gas condenses into small water droplets upon cooling. This rotational motion subjects the gas and liquid components in the exhaust gas to different centrifugal forces. Within the cyclone, the gas, due to its lower density and inertia, moves towards the center of the cyclone. The liquid, due to its higher density and inertia, is pushed towards the periphery of the cyclone. As the cyclone continues to act, the liquid pushed towards the periphery will gradually accumulate and increase in size. When the water droplets reach a certain size, they will break free from the cyclone's restraint due to gravity and drip down along the heat exchange tube wall 21. In one embodiment, a water collection component 30 is provided below the heat exchange tube wall 21. The water collection component 30 has a water collection cavity 31 inside, which is connected to the airflow channel 40. The water collection component 30 is used to collect condensate and enter it into the subsequent cooling cycle.

[0046] In one embodiment, the heat dissipation device further includes a first pipe 60. The heat exchanger 20 has a cooling medium channel 50 for the flow of cooling medium 11. The cooling medium channel 50 has an inlet and an outlet, with the outlet connected to the housing 10. The first pipe 60 connects the housing 10 and the inlet, and a first flow valve 61 is installed on the first pipe 60. The first pipe 60 is used to transport the cooling medium 11 from the housing 10 into the cooling medium channel 50. The cooling medium 11 enters the cooling medium channel 50 through the inlet, exchanges heat with the engine exhaust gas, and then exits from the cooling medium channel 50 back to the housing 10 through the outlet, thus achieving the circulation of the cooling medium 11 within the housing 10. The first flow valve 61 is used to regulate the flow rate of the cooling medium 11 in the first pipe 60. When the exhaust gas temperature is high, the first flow valve 61 is opened, accelerating the flow of the cooling medium 11 from the housing 10 through the first pipe 60 into the cooling medium channel 50, thereby improving the heat exchange efficiency.

[0047] In one embodiment, a first temperature sensor 63 is provided at the airflow channel 40. The ECU (electronic control unit) controls the opening degree of the first flow valve 61 by monitoring the temperature of the first temperature sensor 63. The higher the exhaust gas temperature, the greater the opening degree of the first flow valve 61.

[0048] In one implementation, such as Figure 1 As shown, the heat exchange tube wall 21 extends radially from the outside to the inside in a spiral shape. The spiral cooling medium channel 50 is formed between the multiple layers of heat exchange tube walls 21 arranged radially. The inlet is formed between the axial edges of two adjacent layers of heat exchange tube walls 21. The inlet can be any one of the first inlet 511, the second inlet 512, and the third inlet 513, or it can be a combination of the first inlet 511, the second inlet 512, and the third inlet 513, or the first inlet 511, the second inlet 512, and the third inlet 513 can be set at the same time. The specific setting method can be determined according to the temperature of the exhaust gas. If the exhaust gas temperature is high, multiple cooling medium 11 inlets can be set to increase the flow rate of the cooling medium 11, thereby improving the heat exchange efficiency. The outlet is located between the end of the outermost radial heat exchange tube wall 21 and the second outermost radial heat exchange tube wall 21. The cooling medium 11 enters the spiral cooling medium channel 50 through the first inlet 511, the second inlet 512 or the third inlet 513, and fully exchanges heat with the exhaust gas in the multi-layer heat exchange tube wall 21. It then flows out from the gap between the end of the outermost heat exchange tube wall 21 and the second outermost heat exchange tube wall 21.

[0049] In one embodiment, a first water level gauge 70 is installed inside the water collecting chamber 31. The first water level gauge 70 is used to measure the liquid level in the water collecting chamber 31. The more water in the water collecting chamber 31, the higher the liquid level. When the liquid level reaches a certain predetermined value, the water in the chamber needs to be drained. In another embodiment, a first water outlet valve 71 is also installed on the water collecting component 30. The first water outlet valve 71 is used to drain the condensate in the water collecting chamber 31 into the housing 10. In another embodiment, the first water level gauge 70 may not be installed, and only the first water outlet valve 71 is installed to drain the condensate in the water collecting chamber 31 at regular intervals.

[0050] In one embodiment, the commonly used cooling medium 11 inside the housing 10 is water. A second water level gauge 72 is installed inside the housing 10 to measure the liquid level. When the liquid level reaches a predetermined value, the water inside the housing 10 needs to be drained. In another embodiment, a second outlet valve 73 is installed inside the housing 10 to drain the coolant from the housing 10. In another embodiment, the second water level gauge 72 may be omitted, and a second outlet valve 73 may be installed alone to drain the water from the housing 10 periodically.

[0051] A second aspect of this application provides a vehicle that includes the cooling device of the first aspect. By using this cooling device, the vehicle does not need to be equipped with an additional electric heating device when operating in extremely cold weather, thus reducing vehicle energy consumption and lowering vehicle production costs.

[0052] In one embodiment, the vehicle further includes a second pipe 80, a water processor, and a water pump 81. The inlet and outlet of the second pipe 80 are both connected to the housing 10. The water pump 81 and the water processor are located on the second pipe 80 between the inlet and outlet. A second flow path valve is installed on the second pipe 80. The water processor includes a filter 82 and a cooler 83. The water pump 81 pumps water out of the housing 10, allowing water to circulate in the second pipe 80. In one embodiment, a filter 82 is installed on the second pipe 80. Because the water in the housing 10 circulates continuously, impurities present in various components requiring cooling may enter the housing 10. Additionally, due to incomplete combustion of fuel and evaporation of engine oil, engine exhaust typically contains impurities such as oil mist, soot, and molten aluminates. These impurities adhere to the condensate and enter the water collection unit 30, then enter the housing 10 through the first outlet valve 71. Therefore, the filter 82 is needed to purify the water, filtering out the impurities and ensuring the water quality within the housing 10. In another embodiment, a cooler 83 is installed on the second pipe 80, and the water with a higher temperature inside the tank 10 exchanges heat with the cooler 83 to lower the water temperature inside the tank 10. Preferably, a cooler 83 and a filter 82 are installed on the second pipe 80 at the same time, so that it can exchange heat with the water inside the tank 10 and also filter out impurities in the water.

[0053] In one embodiment, a second flow valve 62 is also provided on the second pipe 80, and a second temperature sensor 84 is provided inside the housing 10. The ECU (electronic control unit) controls the opening degree of the second flow valve 62 by monitoring the temperature of the second temperature sensor 84. The higher the temperature of the second temperature sensor 84, the greater the opening degree of the second flow valve 62.

[0054] In one embodiment, the vehicle further includes an engine and an exhaust gas treatment system. The engine includes an exhaust passage 90, a first sub-passage 91, and a second sub-passage 92. One end of the exhaust passage 90 is connected to the engine cylinder block, and the other end of the exhaust passage 90 is connected to the first sub-passage 91 and the second sub-passage 92. The first sub-passage 91 is connected to an airflow passage 40, and the second sub-passage 92 is connected to the exhaust gas treatment system. Figure 3 As shown, when the engine is running, gasoline and air mix and burn in the cylinder. The exhaust gas after combustion is discharged through exhaust passage 90, which is connected to first sub-passage 91. First sub-passage 91 is connected to airflow passage 40 to guide the exhaust gas discharged from the cylinder into housing 10. Exhaust passage 90 is connected to second sub-passage 92, which is connected to exhaust gas treatment system to after-treat the remaining exhaust gas to reduce emissions and environmental pollution.

[0055] In one embodiment, a first pressure sensor 93 is provided on the first sub-channel 91, and an exhaust bypass valve 95 and a second pressure sensor 94 are provided on the second sub-channel 92, thereby enabling the regulation of the water level inside the housing 10. When the engine ECU (Electronic Control Unit) detects that the water level inside the engine housing 10 is too high, it appropriately increases the opening of the exhaust bypass valve 95 based on the signals from the first pressure sensor 93 and the second pressure sensor 94, allowing the exhaust gas to bypass the housing 10 and directly enter the exhaust gas treatment system before being discharged into the atmosphere. When the engine ECU detects that the water level inside the engine housing 10 is too low, it appropriately decreases the opening of the exhaust bypass valve 95 based on the signals from the first pressure sensor 93 and the second pressure sensor 94, increasing the amount of exhaust gas passing through the housing 10, thereby restoring the engine water level to its normal value. Preferably, a one-way valve 96 is also provided on the second sub-channel 92 to prevent backflow of air from damaging the exhaust bypass valve 95.

[0056] In one embodiment, the engine further includes a turbocharger for increasing intake air density. The turbocharger includes a compressor 98 and a turbine 97. The turbine 97 is disposed on a first sub-channel 91 or a second sub-channel 92. Exhaust gas enters the turbine 97 through the first sub-channel 91 or the second sub-channel 92, impacting the turbine 97 blades and causing the turbine 97 to rotate at high speed, thereby driving the compressor 98 to compress the engine intake air.
