Description

Technical Field

[0001] This invention belongs to the field of vehicle cooling system technology, and more specifically, relates to a heat dissipation device and a vehicle. Background Technology

[0002] The car water tank, also known as the radiator, is a major component of the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the engine's water jacket, flows to the radiator where the heat is dissipated, and then flows back into the water jacket to circulate, thus preventing the engine from overheating.

[0003] Traditional radiators are exposed to the elements and require airflow for physical cooling. Under harsh conditions, radiators are prone to damage or blockage. If a radiator is damaged, coolant will leak, the cooling system will lose its cooling capacity, the entire vehicle's powertrain will overheat rapidly, and the vehicle will become unusable. If a radiator is blocked, the cooling capacity will be insufficient, the engine coolant temperature will exceed the limit, the engine's self-protection function will activate, the entire vehicle will lose power, seriously affecting driving safety and driving experience. Summary of the Invention

[0004] The purpose of this invention is to provide a heat dissipation device and vehicle, which aims to solve the technical problem that radiators in the prior art are prone to damage or blockage.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a heat dissipation device, comprising:

[0006] The heat dissipation housing has an inner cavity that forms a heat dissipation air duct extending in the vertical direction; the bottom of the heat dissipation housing is provided with an air inlet and the top is provided with an air outlet, and the air inlet and the air outlet are both connected to the heat dissipation air duct.

[0007] A filter assembly is disposed at the air inlet and covers the air inlet;

[0008] A fan is disposed at the air outlet and covers the air outlet; and

[0009] The radiator body is disposed within the heat dissipation duct; the radiator body has a water inlet and a water outlet, both of which extend to the heat dissipation housing.

[0010] The beneficial effects of the heat dissipation device provided by the present invention are as follows: Compared with the prior art, the heat dissipation device of the present invention forms a heat dissipation air duct in the inner cavity of the heat dissipation shell, and the filter component covers the air inlet of the heat dissipation air duct, which can filter out impurities such as willow catkins, insects, and sand, so that the air entering the heat dissipation air duct is clean air, and avoids the heat dissipation body located in the heat dissipation air duct from being blocked or damaged by collision, thereby ensuring the normal operation of the heat dissipation device and improving the service life of the heat dissipation device.

[0011] The fan covers the air outlet of the heat dissipation duct. The heat dissipation shell, filter components and fan combination can form a relatively closed space for the heat dissipation duct, so as to increase the wind speed and air volume passing through the heat dissipation duct and improve the heat dissipation efficiency.

[0012] Since the air intake is located at the bottom of the heat sink housing, it does not need to cover the entire heat sink housing. Therefore, the requirement for the opening area of ​​the front bumper is not high. In addition, the opening position of the front bumper can be reduced, thereby reducing the overall wind resistance of the vehicle and saving fuel consumption.

[0013] In one possible implementation, the heat sink body includes:

[0014] Multiple heat sinks are arranged sequentially in a vertical direction; each heat sink is provided with a serpentine flow channel; the four periphery edges of each heat sink are connected to the inner peripheral wall of the heat dissipation channel.

[0015] Each heat sink is horizontally filled within the heat dissipation duct to fully utilize the space of the duct, increase the heat dissipation area of ​​the heat sink, and prevent cool air from being lost without passing through the heat sink.

[0016] In some embodiments, each of the heat sinks is inclined in the vertical direction.

[0017] By tilting multiple heat sinks, compared to arranging them vertically, the area of ​​the heat sinks can be increased, which increases the area for coolant flow and improves heat dissipation efficiency. At the same time, the width of the heat sink housing can be reduced, thus reducing the space occupied by the heat dissipation device.

[0018] In some embodiments, the heat dissipation housing has a first side plate and a second side plate that are arranged opposite to each other and parallel to the vertical direction; the air inlet is located at the bottom of the first side plate, and the air outlet is located at the top of the second side plate; the water inlet and the water outlet are both located on the second side plate.

[0019] The air intake is located at the bottom of the first side panel, so it does not need to cover the entire first side panel. Therefore, the requirement for the opening area of ​​the front bumper is not high. In addition, the opening position can be lowered, reducing the wind resistance of the whole vehicle and saving fuel consumption.

[0020] The air vents are located at the top of the second side panel, which increases the airflow path of the heat dissipation duct and prevents the rear airflow from being blocked by the engine compartment cover.

[0021] Both the inlet and outlet are located on the second side plate for easy connection with the engine water jacket.

[0022] In some embodiments, the heat sink near the air inlet is defined as a primary heat sink, the lower end of the primary heat sink is connected to the first side plate and located above the air inlet, and the upper end of the primary heat sink extends upward at an angle and is connected to the second side plate.

[0023] The primary heat sink is not opposite to the air inlet. The primary heat sink can bypass the filter components and allow air to enter the heat dissipation duct without blocking the wind or changing the airflow direction.

[0024] In some embodiments, the heat sink located above the primary heat sink is defined as the secondary heat sink, the lower end of the secondary heat sink is connected to the first side plate, and the upper end of the secondary heat sink extends obliquely upward and is connected to the second side plate.

[0025] The liquid inlet of the secondary heat sink is connected to the liquid outlet of the primary heat sink via a water supply pipeline.

[0026] The arrangement of the secondary heat sink reduces the space occupied by the primary and secondary heat sinks in the lower part of the heat dissipation duct. Moreover, after the airflow passes through the primary heat sink, it travels a certain distance before entering the secondary heat sink. During the flow, the airflow can also radiate heat outward through the heat sink shell, thereby reducing the temperature of the airflow passing through the secondary heat sink.

[0027] In some embodiments, the number of heat sinks is four, and the heat sink located above the secondary heat sink is defined as the tertiary heat sink, and the heat sink located above the tertiary heat sink is defined as the quaternary heat sink.

[0028] The lower end of the third-stage heat dissipation plate is connected to the upper end of the second-stage heat dissipation plate and is located below the air outlet. The upper end of the third-stage heat dissipation plate extends upward at an angle and is connected to the first side plate.

[0029] The lower end of the fourth-stage heat dissipation plate is connected to the first side plate and is located above the upper end of the third-stage heat dissipation plate. The upper end of the fourth-stage heat dissipation plate extends upward at an angle and is connected to the second side plate and is located above the air outlet.

[0030] The third and fourth heat sinks are located in the upper part of the heat dissipation duct. By making full use of the space in the heat dissipation duct, the number of heat sinks is optimized, ensuring the heat exchange efficiency of the coolant while reducing the cost of the heat exchange device.

[0031] In some embodiments, a first heat sink assembly is provided on the outer wall of the first side plate, and the first heat sink assembly is located between the upper end of the primary heat sink and the lower end of the secondary heat sink.

[0032] The first heat sink assembly can absorb heat from the heat dissipation duct, especially the heat from the airflow after passing through the first heat sink, so as to reduce the airflow temperature after passing through the second heat sink and increase the heat exchange performance of the second heat sink.

[0033] In some embodiments, a second heat sink assembly is provided on the outer wall of the second side plate, and the second heat sink assembly is located below the air outlet.

[0034] The second heat sink assembly is used to absorb heat from the heat dissipation duct, reduce the ambient temperature of the heat dissipation duct, and thus improve the heat exchange efficiency of the primary and secondary heat sinks.

[0035] In some embodiments, a third heat sink assembly is provided on the outer wall of the first side plate. The third heat sink assembly is located between the upper end of the third-level heat sink and the lower end of the fourth-level heat sink, and the third heat sink assembly corresponds directly to the air inlet of the fan.

[0036] The third heat sink group can absorb heat in the heat dissipation duct. The third heat sink group is located between the third and fourth heat sinks. In particular, it can absorb the heat of the airflow after passing through the third heat sink, so as to reduce the ambient temperature in the upper part of the heat dissipation duct and improve the heat exchange efficiency of the third and fourth heat sinks.

[0037] In one possible implementation, a through hole is provided on the bottom plate of the heat dissipation housing, and a plug is provided inside the through hole.

[0038] The sealing plug functions similarly to a one-way valve. Opening the sealing plug allows impurities accumulated on the bottom plate of the heat sink housing to be removed through the through-hole, ensuring a clean heat dissipation duct and extending the service life of the heat dissipation device.

[0039] The present invention also provides a vehicle including the above-described heat dissipation device.

[0040] The vehicle provided by this invention, by employing the aforementioned cooling device, can improve cooling efficiency, extend service life, reduce overall vehicle wind resistance, and save fuel consumption. Attached Figure Description

[0052] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0053] The automotive cooling system is an indispensable part of the normal operation of the car engine and related components. Its main function is to control the temperature of the engine and its related components (such as the transmission and battery) to prevent performance degradation or malfunction due to overheating.

[0054] The automotive cooling system consists of a water pump, radiator, cooling fan, thermostat, coolant tank, water jackets in the engine block and cylinder head, and other auxiliary devices. The cooling system works by circulating coolant through pipes and passages within the engine. After flowing through the engine, the coolant flows to the radiator, where the heat in the coolant is dissipated into the air.

[0055] The radiator is typically located at the front of the car and is in contact with the outside air. After the coolant flows out of the engine, it is pumped into the radiator, where it releases heat into the outside air through a fan or natural convection before returning to the engine to continue the cycle.

[0056] A radiator consists of an inlet chamber, an outlet chamber, and a radiator core. The radiator core is composed of numerous fine cooling tubes and fins. The cooling tubes mostly have a flat, round cross-section to reduce air resistance and increase the heat transfer area. The cooling tubes and fins are mostly made of aluminum and are installed perpendicular to the direction of airflow. Coolant flows inside the radiator core, while air passes outside. The hot coolant cools as it dissipates heat to the air, while the cool air warms up by absorbing the heat released by the coolant; therefore, a radiator is a heat exchanger.

[0057] Traditional radiators are located behind the fan and exposed to the outside, requiring airflow for physical cooling. Under harsh operating conditions, radiators are prone to damage or blockage.

[0058] For example, because the gap between the flat tubes and fins of the radiator is small, impurities such as willow catkins and insects can easily clog the radiator. If it is not disassembled and cleaned in time, it will affect the vehicle's heat dissipation capacity, the engine water temperature will exceed the limit, the engine's self-protection function will be activated, the vehicle will lose power, and seriously affect driving safety and driving experience.

[0059] For example, since the flat tubes and fins of the radiator are made of aluminum, the tube walls are relatively thin in order to improve heat dissipation capacity. They are easily damaged by external impacts. Once damaged, the coolant will leak out, the cooling system will lose the heat conduction of the coolant, the entire vehicle's powertrain will rapidly overheat, and the entire vehicle will become unusable.

[0060] Please refer to the following: Figures 1 to 4 The heat dissipation device provided by the present invention will now be described. The heat dissipation device includes a heat dissipation shell 1, a filter assembly 2, a fan 3, and a radiator body 4. The heat dissipation shell 1 forms a heat dissipation air duct 10 extending in the vertical direction within its inner cavity; the heat dissipation shell 1 has an air inlet 111 at its bottom and an air outlet 121 at its top, both of which are connected to the heat dissipation air duct 10; the filter assembly 2 is disposed at the air inlet 111 and covers the air inlet 111; the fan 3 is disposed at the air outlet 121 and covers the air outlet 121; the radiator body 4 is disposed within the heat dissipation air duct 10; the radiator body 4 has a water inlet 122 and a water outlet 123, both of which extend to the heat dissipation shell 1.

[0061] It should be noted that the up-down direction defined in the embodiments of the present invention refers to the vertical direction of the vehicle body, not the vertical direction. Positioning the air inlet 111 at the bottom and the air outlet 121 at the top conforms to the natural upward flow trend of cold air.

[0062] The heat sink 1 is mounted at the front of the engine. The heat sink 1 is preferably a hexahedral structure, with its inner cavity being a heat dissipation duct 10. The height of the heat dissipation duct 10 is greater than its length and width, which increases the ventilation path and improves the air intake speed and volume.

[0063] The air inlet 111 is located at the bottom of the heat sink 1, and the air outlet 121 is located at the top of the heat sink 1. This can be understood as the air inlet 111 being located on the bottom plate of the heat sink 1 and the air outlet 121 being located on the top plate of the heat sink 1. Alternatively, the air inlet 111 being located at the bottom of one of the side plates of the heat sink 1 and the air outlet 121 being located at the top of one of the side plates of the heat sink 1. In this embodiment, the specific directions of the air inlet 111 and the air outlet 121 are not limited, as long as they conform to the airflow pattern of bottom air intake and top air exhaust.

[0064] It should be noted that the air intake 111 must be connected to the opening on the front bumper. In other words, an opening needs to be made on the front bumper, and the opening corresponds to the air intake 111. Outside air enters the air intake 111 through the opening and passes through the cooling duct 10. Since the air intake 111 is located at the bottom of the cooling housing 1, it does not need to cover the entire cooling housing 1. Therefore, the opening area requirement of the front bumper is not high, and the opening position can be lowered, thereby reducing the overall wind resistance of the vehicle and saving fuel consumption.

[0065] The filter assembly 2 is located at and covers the air inlet 111. The filter assembly 2 can employ an active filtration structure with motor-driven centrifugal blades or a fixed cyclone blade structure. The motor-driven centrifugal blade structure reduces the workload of the fan 3 and improves filtration efficiency; the fixed cyclone blade structure reduces the overall vehicle cost. Of course, the filter assembly 2 can also use a bladed filter structure commonly found in existing technologies. This embodiment does not limit the specific structure of the filter assembly 2, as long as it can coarsely filter the airflow entering the cooling duct 10, removing impurities such as willow catkins and insects.

[0066] Fan 3 is positioned at and covers air outlet 121. Fan 3 increases the airflow speed and volume through the cooling duct 10, allowing cool air to pass quickly and in large quantities through the cooling channel for heat exchange with the radiator body 4. Specifically, fan 3 is an electric motor fan 3, which is electrically connected to the vehicle's electronic control unit (ECU). The ECU controls the duty cycle of fan 3. Preferably, at least two fans 3 are provided in this embodiment. On the one hand, multiple fans 3 can make the ventilation of the cooling duct 10 more uniform; on the other hand, if one fan 3 fails, it will not affect the ventilation of the cooling duct 10.

[0067] In environments with high ambient temperatures, fan 3 is turned on to accelerate the flow rate and volume of cold air through the cooling duct 10, thereby improving the heat dissipation efficiency of the radiator body 4. In environments with low ambient temperatures, fan 3 is turned off, and the ventilation volume of the cooling duct 10 drops sharply, which can reduce the heat dissipation capacity and increase the cabin temperature.

[0068] The radiator body 4 is used for the flow of coolant. The inlet 122 and outlet 123 of the radiator body 4 are connected to the engine water jacket. After flowing out of the engine water jacket, the coolant is pumped into the inlet 122, flows through the radiator body 4, and then re-enters the engine water jacket through the outlet 123. During the flow of coolant through the radiator body 4, cold air from the cooling duct 10 also passes through the radiator body 4. The hot coolant dissipates heat into the cooling duct 10 and becomes cooler, while the cold air absorbs the heat dissipated by the coolant and becomes warmer. The cold air carries away the heat from the coolant, thus dissipating its heat.

[0069] Since the radiator body 4 is located inside the heat dissipation duct 10 and is wrapped by the heat dissipation shell 1, the service life and application scenarios of the radiator body 4 can be improved.

[0070] Compared with the prior art, the heat dissipation device provided by the present invention has a heat dissipation air duct 10 formed in the inner cavity of the heat dissipation shell 1. The filter component 2 covers the air inlet 111 of the heat dissipation air duct 10, which can filter out impurities such as willow catkins, insects, and sand, so that the air entering the heat dissipation air duct 10 is clean air. This avoids the radiator body 4 located in the heat dissipation air duct 10 from being blocked or damaged by collision, thereby ensuring the normal operation of the heat dissipation device and improving the service life of the heat dissipation device.

[0071] The fan 3 covers the air outlet 121 of the heat dissipation duct 10. The combination of the heat dissipation housing 1, the filter component 2 and the fan 3 can make the heat dissipation duct 10 form a relatively closed space, so as to increase the wind speed and air volume passing through the heat dissipation duct 10 and improve the heat dissipation efficiency.

[0072] Since the air inlet 111 is located at the bottom of the heat dissipation housing 1, it does not need to cover the entire heat dissipation housing 1. Therefore, the requirement for the opening area of ​​the front bumper is not high, and the opening position can be lowered, thereby reducing the wind resistance of the whole vehicle and saving fuel consumption.

[0073] In some embodiments, the heat sink body 4 may be adopted as follows: Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 The radiator body 4 includes multiple heat dissipation plates. The multiple heat dissipation plates are distributed sequentially in the vertical direction; each heat dissipation plate is provided with a serpentine flow channel; the four periphery edges of each heat dissipation plate are connected to the inner peripheral wall of the heat dissipation duct 10.

[0074] Since the heat dissipation duct 10 extends vertically, its height is greater than its length and width. To increase the heat dissipation area of ​​the radiator body 4 and improve the utilization rate of cold air, multiple heat dissipation plates are installed and distributed sequentially along the vertical direction. It should be noted that a liquid infusion pipeline is connected between every two adjacent heat dissipation plates.

[0075] The heat sink can be viewed as being formed by flat tubes arranged in a serpentine pattern. The inner cavity of the serpentine tubes is a serpentine flow channel, and fins are distributed on the outer wall of the tubes. Coolant passes through the tubes and dissipates heat outward through the fins. The serpentine tubes also have ventilation gaps through which air passes to carry away the heat dissipated by the fins.

[0076] The heat sink can also be viewed as a flat plate structure with serpentine flow channels distributed within it. As the coolant flows through these channels, it dissipates heat outwards through the flat plate structure. The flat plate structure also has strip-shaped air vents through which air passes, carrying away the heat from the heat sink.

[0077] It should be noted that both the serpentine flat tube and the flat plate structure are conventional technologies for cooling the coolant. Therefore, this embodiment does not elaborate on the structure of the heat sink, as long as it allows the coolant to flow in a serpentine pattern within it. The serpentine flow channel can increase the flow path of the coolant, thereby improving its heat dissipation efficiency.

[0078] Although this embodiment does not limit the specific structure of the heat sink, it limits the specific position of the heat sink. It requires that the four edges of the heat sink be connected to the inner peripheral wall of the heat dissipation duct 10. In other words, in the direction of airflow, each heat sink is horizontally filled in the heat dissipation duct 10 to make full use of the space of the heat dissipation duct 10, increase the heat dissipation area of ​​the heat sink, and prevent cold air from being lost without passing through the heat sink.

[0079] In some embodiments, the plurality of heat sinks described above may employ, for example... Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 Each heat sink is tilted in the vertical direction.

[0080] It should be noted that the tilt direction of each heat sink can be exactly the same or different, and similarly, the tilt angle can be exactly the same or different. The tilt direction and tilt angle of each heat sink depend on the height of the heat dissipation duct 10 and the positions of the air inlet 111 and the air outlet 121.

[0081] By tilting multiple heat sinks, compared to arranging them vertically, the area of ​​the heat sinks can be increased, which increases the area for coolant flow and improves heat dissipation efficiency. At the same time, the width of the heat sink housing 1 can be reduced, thus reducing the space occupied by the heat dissipation device.

[0082] In some embodiments, the heat sink 1 may be as follows: Figure 1 , Figure 2 and Figure 3 The structure shown is described in the following document. Figure 1 , Figure 2 and Figure 3 The heat dissipation housing 1 has a first side plate 11 and a second side plate 12 that are arranged opposite to each other and parallel to the vertical direction; the air inlet 111 is located at the bottom of the first side plate 11, and the air outlet 121 is located at the top of the second side plate 12; the water inlet 122 and the water outlet 123 are both located on the second side plate 12.

[0083] In the longitudinal direction of the vehicle body, the first side panel 11 is located in front of the second side panel 12, with the first side panel 11 facing the front bumper and the second side panel 12 facing the engine.

[0084] The air intake 111 is located at the bottom of the first side panel 11, meaning that the air intake direction of the air intake 111 is the front-to-back direction of the vehicle body, corresponding to the front-to-back opening on the front bumper. Since the air intake 111 is located at the bottom of the first side panel 11, it does not need to cover the entire first side panel 11, so the requirement for the opening area of ​​the front bumper is not high. Moreover, the opening position can be lowered to increase the design diversity of the front bumper, and it can also reduce the overall wind resistance of the vehicle and save fuel consumption.

[0085] The air vent 121 is located at the top of the second side panel 12 and is also arranged along the front and rear direction of the vehicle body. On the one hand, it is convenient to integrate and install the fan 3. On the other hand, it can increase the airflow path of the heat dissipation duct 10, and the rear air outlet will not be blocked by the engine compartment cover, thus preventing the air outlet from being obstructed.

[0086] Both the inlet 122 and the outlet 123 are located on the second side plate 12, facing the engine, to facilitate communication with the engine water jacket and optimize the distribution path of the pipes connecting the engine water jacket and the cooling device.

[0087] In some embodiments, the plurality of heat sinks described above may employ, for example... Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 The heat sink near the air inlet 111 is defined as the primary heat sink 41. The lower end of the primary heat sink 41 is connected to the first side plate 11 and located above the air inlet 111. The upper end of the primary heat sink 41 extends upward at an angle and is connected to the second side plate 12.

[0088] If the first side plate 11 is positioned in front of the second side plate 12, then the primary heat sink 41 is inclined upwards from front to back, and the lower end of the primary heat sink 41 is positioned above the air inlet 111. In the air inlet direction of the air inlet 111, the primary heat sink 41 is not opposite to the air inlet 111. In this way, the primary heat sink 41 can avoid the filter assembly 2 and allow air to enter the heat dissipation duct 10 without blocking the wind or changing the airflow direction.

[0089] Specifically, outside cold air enters the heat dissipation duct 10 after passing through the filter component 2. Since there is no obstruction behind the air inlet 111, only the second side plate 12, the cold air flows upward under the action of the fan 3. Even if some of the cold air reverses after hitting the second side plate 12, it will still flow upward under the action of the fan 3.

[0090] Since there is no heat sink behind the air inlet 111, a large amount of cold air can quickly enter the heat dissipation duct 10, and the cold air flows upward and will not change direction and flow back. On the one hand, this avoids impacting the filter component 2, and on the other hand, it can also avoid the airflow direction from becoming chaotic and turbulent.

[0091] It should be noted that the water inlet 122 is connected to the primary heat sink 41. Specifically, a water supply pipe is provided on the inner wall of the enclosed housing, connecting the water inlet 122 and the upper corner of the primary heat sink 41. Since the water inlet 122 is located on the second side plate 12, and the upper end of the primary heat sink 41 is connected to the second side plate 12, the coolant enters first from the upper corner of the primary heat sink 41. The coolant can exit from either the other upper corner or the lower corner of the primary heat sink 41.

[0092] In some embodiments, the plurality of heat sinks described above may employ, for example... Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 The heat sink located above the primary heat sink 41 is defined as the secondary heat sink 42. The lower end of the secondary heat sink 42 is connected to the first side plate 11, and the upper end of the secondary heat sink 42 extends upward at an angle and is connected to the second side plate 12. The liquid inlet end of the secondary heat sink 42 and the liquid outlet end of the primary heat sink 41 are connected by a water supply pipeline.

[0093] The primary heat sink 41 is inclined upward from front to back, and its upper end is connected to the water inlet 122. In order to ensure that the secondary heat sink 42 is connected to the primary heat sink 41, the secondary heat sink 42 has two distribution methods: one is inclined upward from back to front, and the other is inclined upward from front to back. In the first method, since the inclination direction of the primary heat sink 41 and the secondary heat sink 42 is opposite, the angle between them is large, resulting in a large space occupied by them. This requires reducing the number of heat sinks, that is, reducing the heat dissipation area, thereby reducing the heat dissipation efficiency.

[0094] Therefore, this embodiment adopts the second distribution method, that is, the secondary heat sink 42 is inclined upward from front to back, which is the same as the inclination direction of the primary heat sink 41. Preferably, the angle between the two and the vertical direction is also the same.

[0095] The arrangement of the secondary heat sink 42 as described above reduces the space occupied by the primary heat sink 41 and the secondary heat sink 42 in the lower part of the heat dissipation duct 10, thus providing space for multiple heat sinks to be arranged above the secondary heat sink 42, making full use of the internal cavity structure of the heat sink housing 1; moreover, after the airflow passes through the primary heat sink 41, it flows a certain distance before entering the secondary heat sink 42, and during the flow, it can also radiate heat outward through the heat sink housing 1, thereby reducing the airflow temperature passing through the secondary heat sink 42.

[0096] It should be noted that, in order to optimize the distribution of the water supply pipeline, the water inlet of the secondary heat dissipation plate 42 and the water outlet of the primary heat dissipation plate 41 are distributed vertically in correspondence. If the water outlet of the primary heat dissipation plate 41 is the upper end, then the water inlet of the secondary heat dissipation plate 42 is also the upper end; if the water outlet of the primary heat dissipation plate 41 is the lower end, then the water inlet of the secondary heat dissipation plate 42 is also the lower end.

[0097] Since the secondary heat sink 42 and the primary heat sink 41 are tilted in the same direction, in order to improve the heat dissipation effect of the space between the secondary heat sink 42 and the primary heat sink 41, in some embodiments, the first side plate 11 may also adopt the following... Figure 2 and Figure 4 The structure shown is described in the following document. Figure 2 and Figure 4 The outer wall of the first side plate 11 is provided with a first heat sink group 51, which is located between the lower end of the first heat sink 41 and the lower end of the second heat sink 42.

[0098] The first heat sink assembly 51 includes multiple heat dissipation teeth. One end of each heat dissipation tooth is connected to the outer wall of the first side plate 11, and the other end extends outward from the first side plate 11. There is a heat dissipation gap between each pair of adjacent heat dissipation teeth. Preferably, the multiple heat dissipation teeth are distributed in parallel, and each heat dissipation tooth extends in the vertical direction.

[0099] The heat in the heat dissipation duct 10 is transferred to each heat dissipation tooth through the first side plate 11, and the heat is dissipated to the outside through each heat dissipation tooth to reduce the airflow temperature in the heat dissipation duct 10.

[0100] The first heat sink group 51 can absorb the heat in the heat dissipation duct 10. The first heat sink group 51 is located between the first-stage heat sink and the second-stage heat sink. In particular, it can absorb the heat of the airflow after passing through the first-stage heat sink 41, so as to reduce the airflow temperature after passing through the second-stage heat sink 42 and increase the heat exchange performance of the second-stage heat sink 42.

[0101] In addition, a second heat sink assembly 52 is provided on the outer wall of the second side plate 12, and the second heat sink assembly 52 is located below the air outlet 121.

[0102] The structure of the second heat sink group 52 is the same as that of the first heat sink group 51, and it also includes multiple spaced and parallel heat dissipation teeth. However, the height of the heat dissipation teeth in the second heat sink group 52 is greater than the height of the heat dissipation teeth in the first heat sink group 51.

[0103] The second heat sink group 52 has the same function as the first heat sink group 51, which is to absorb the heat in the heat dissipation duct 10, reduce the ambient temperature of the heat dissipation duct 10, and thus improve the heat exchange efficiency of the primary heat sink 41 and the secondary heat sink 42.

[0104] Since the cooling device is installed in the engine compartment, the height of the cooling housing 1 cannot be too high due to the installation location and the need to adapt to the engine water jacket. Therefore, within the limited height of the cooling duct 10, the number of cooling plates needs to be arranged reasonably. If there are too many cooling plates, the overall cost of the cooling device will be high, and the coolant flow will be large; if there are too few cooling plates, the space of the cooling duct 10 cannot be fully utilized, and the heat exchange efficiency will be low.

[0105] To address the aforementioned issues, in some embodiments, the plurality of heat sinks may also employ, for example... Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 There are four heat sinks. The heat sink above the secondary heat sink 42 is defined as the tertiary heat sink 43, and the heat sink above the tertiary heat sink 43 is defined as the quaternary heat sink 44.

[0106] The lower end of the third-stage heat sink 43 is connected to the upper end of the second-stage heat sink 42 and is located below the air outlet 121. The upper end of the third-stage heat sink 43 extends upward at an angle and is connected to the first side plate 11. The lower end of the fourth-stage heat sink 44 is connected to the first side plate 11 and is located above the upper end of the third-stage heat sink 43. The upper end of the fourth-stage heat sink 44 extends upward at an angle and is connected to the second side plate 12 and is located above the air outlet 121.

[0107] Four heat sinks are provided. The first-level heat sink 41 and the second-level heat sink 42 are located in the lower half of the heat dissipation duct 10, while the third-level heat sink 43 and the fourth-level heat sink 44 are located in the upper half of the heat dissipation duct 10. By making full use of the space of the heat dissipation duct 10, the number of heat sinks is optimized, ensuring the heat exchange efficiency of the coolant while reducing the cost of the heat exchange device.

[0108] In addition, the three-stage heat sink 43 and the four-stage heat sink 44 surround and surround the air outlet 121 above and below, avoiding the position of the air outlet 121. This will not affect the air extraction of the fan 3, nor will it obstruct the airflow and cause turbulence.

[0109] Specifically, the third-stage heat sink 43 is inclined upwards from back to front, and its inclination direction is opposite to that of the second-stage heat sink 42, with the two arranged at an angle. With this arrangement, firstly, the lower end of the third-stage heat sink 43 can be directly connected to the upper end of the second-stage heat sink 42, eliminating the need for a water supply pipe, or if a water supply pipe is present, its path and length are short; secondly, while avoiding the air outlet 121, compared to being parallel to the second-stage heat sink 42, it increases the distance between the third-stage heat sink 43 and the second-stage heat sink 44, and optimizes the distance between the third-stage heat sink 43 and the fourth-stage heat sink 44.

[0110] The fourth-level heat sink 44 is inclined upwards from front to back, opposite to the inclination direction of the third-level heat sink 43. The two are set at an angle and are arranged in a diffused manner around the air outlet 121 above and below to increase the air outlet space, so that hot air can be quickly drawn out by the fan 3 and avoid the accumulation of hot air.

[0111] Preferably, please refer to Figure 2 and Figure 4 Based on the above implementation, a third heat sink group 53 is provided on the outer wall of the first side plate 11. The third heat sink group 53 is located between the upper end of the third-level heat sink 43 and the lower end of the fourth-level heat sink 44, and the third heat sink group 53 corresponds to the air inlet end of the fan 3.

[0112] The structure of the third heat sink group 53 is the same as that of the first heat sink group 51, and it also includes multiple spaced and parallel heat dissipation teeth. The heat in the heat dissipation duct 10 is transferred to each heat dissipation tooth through the first side plate 11, and the heat is dissipated to the outside through each heat dissipation tooth to reduce the airflow temperature in the heat dissipation duct 10.

[0113] The third heat sink group 53 can absorb the heat in the heat dissipation duct 10. The third heat sink group 53 is located between the third-stage heat sink and the fourth-stage heat sink. In particular, it can absorb the heat of the airflow after passing through the third-stage heat sink 43, so as to reduce the ambient temperature of the upper part of the heat dissipation duct 10 and improve the heat exchange efficiency of the third-stage heat sink 43 and the fourth-stage heat sink 44.

[0114] In some embodiments, the above-mentioned heat dissipation device may also employ, for example... Figure 2 The structure shown is described in the following document. Figure 2 A through hole is provided on the bottom plate of the heat dissipation housing 1, and a sealing plug 13 is provided in the through hole.

[0115] It should be noted that even though the air inlet 111 is equipped with a filter component 2, some fine particles and water droplets will still enter the heat dissipation duct 10 through the filter component 2 and accumulate on the bottom plate of the heat dissipation shell 1 under the action of gravity.

[0116] The sealing plug 13 functions similarly to a one-way valve. Opening the sealing plug 13 allows impurities accumulated on the bottom plate of the heat sink housing 1 to be removed through the through hole, ensuring the heat dissipation air duct 10 is clean and extending the service life of the heat dissipation device.

[0117] Based on the same inventive concept, this application also provides a vehicle including the above-described heat dissipation device.

[0118] The vehicle provided by this invention, by employing the aforementioned cooling device, can improve cooling efficiency, extend service life, reduce overall vehicle wind resistance, and save fuel consumption.

[0119] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
