Description

Technical Field

[0001] This application relates to the field of vehicle heat dissipation technology, and more particularly to heat dissipation devices, heat exchange devices, heat dissipation systems, and vehicles. Background Technology

[0002] With the improvement of living standards, cars have become the main means of transportation for families. Some components in a car generate heat during operation, forming heat sources. These heat sources are primarily dissipated through heat dissipation modules. However, existing heat dissipation modules are not very efficient and cannot effectively cool the heat sources. Summary of the Invention

[0003] This application provides a heat dissipation device, a heat exchange device, a heat dissipation system, and a vehicle to solve the problem of poor heat dissipation efficiency of existing heat dissipation modules.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] In a first aspect, embodiments of this application provide a heat dissipation device, including a mixing component. A heat exchange channel is formed inside the mixing component. The mixing component is provided with a first inlet and a second inlet. The heat exchange channel communicates with the first and second inlets. The first inlet is used to allow the material to be heat-exchanged to enter the heat exchange channel, and the second inlet is used to introduce cooling gas, so as to achieve direct contact heat exchange between the material to be heat-exchanged and the cooling gas.

[0006] The heat dissipation device provided in this application embodiment allows the material to be heat-exchanged to enter the heat exchange channel through a first inlet, while cooling gas can enter the heat exchange channel through a second inlet to exchange heat with the material, thus removing heat from the material. Because the material directly contacts the cooling gas for heat exchange, the cooling efficiency is higher, ensuring the heat dissipation efficiency of the device.

[0007] In some embodiments, the heat exchange material is in a liquid state or a gas-liquid mixture state.

[0008] In some embodiments, the mixing element is further provided with an outlet, and the heat exchange passage is connected to the outlet. The outlet is used to allow the hot gas after heat exchange and the cooled liquid to flow out.

[0009] In some embodiments, the outlet includes a first outlet and a second outlet. The first outlet is used to allow the hot gas after heat exchange to flow out, and the second outlet is used to allow the cooled liquid to flow out.

[0010] In some embodiments, the heat dissipation device further includes a flow guide. The flow guide is connected to the mixing element and is used to introduce the material to be heat exchanged into the heat exchange channel.

[0011] In some embodiments, a drainage channel is formed inside the drainage element, with one end extending into the heat exchange channel.

[0012] In some embodiments, the end of the draining element that extends into the heat exchange channel has a flow port.

[0013] In some embodiments, the heat dissipation device further includes a spray head. The spray head is disposed at the flow inlet and covers the flow inlet. The spray head is used to spray the material to be exchanged, so that the material to be exchanged becomes a gas-liquid mixture.

[0014] In some embodiments, the spray head has a spray nozzle, which is connected to the first inlet.

[0015] In some embodiments, the drainage channel includes a first drainage channel and a second drainage channel. One end of the first drainage channel is connected to one end of the second drainage channel, and the other end of the second drainage channel forms a flow opening. The extending directions of the first drainage channel and the second drainage channel intersect.

[0016] In some embodiments, a blocking portion is formed within the second drainage channel. The blocking portion extends along the extending direction of the second drainage channel.

[0017] In some embodiments, along the extending direction of the blocking portion, the cross-sectional area of ​​the blocking portion near the flow port is smaller than the cross-sectional area of ​​the blocking portion away from the flow port.

[0018] In some embodiments, the cross-sectional area of ​​the blocking portion gradually decreases from the end of the blocking portion away from the flow port to the end of the blocking portion closer to the flow port.

[0019] In some embodiments, the blocking part has a conical structure.

[0020] In some embodiments, the mixing component includes a first mixing component and a second mixing component. A first heat exchange channel is formed inside the first mixing component. The second mixing component is connected to the first mixing component and has a second heat exchange channel formed inside it, communicating with the first heat exchange channel. The first heat exchange channel and the second heat exchange channel form a heat exchange channel.

[0021] In some embodiments, the first hybrid component and the second hybrid component are detachably connected.

[0022] In some embodiments, the second heat exchange channel includes a first sub-heat exchange channel and a second sub-heat exchange channel. One end of the first sub-heat exchange channel is connected to the first heat exchange channel and extends in the same direction as the first heat exchange channel. The other end of the first sub-heat exchange channel is connected between the two ends of the second sub-heat exchange channel, and the extension direction of the second sub-heat exchange channel intersects with the extension direction of the first sub-heat exchange channel. A first outlet and a second outlet are respectively formed at the two ends.

[0023] Secondly, embodiments of this application provide a heat exchange device, including a heat sink. The heat sink forms an independent main channel and a heat dissipation channel. The main channel and the heat dissipation channel are used for heat exchange.

[0024] The heat exchange device provided in this application embodiment allows a liquid medium for heat exchange with the vehicle's heat source to circulate in the main channel. When the liquid medium flows within the main channel, its heat is transferred to the heat exchange device. At this time, external airflow carries away the heat transferred to the heat exchange device. Simultaneously, a heat exchange medium that exchanges heat with the liquid medium circulates within the heat dissipation channel. Thus, during the flow of the heat exchange medium within the heat dissipation channel, the heat from the liquid medium can be directly transferred to the heat exchange medium through the heat exchange device, allowing direct heat transfer between the two. This further improves the heat exchange efficiency of the heat exchange device, increasing the heat exchange efficiency of the liquid medium at the heat exchange device, and consequently improving the heat exchange efficiency of the heat exchange device for the vehicle's heat-generating components.

The opening of the main channel communicates with one of the first dispensing ports. The opening of the heat dissipation channel communicates with another first dispensing port.

[0038] In some embodiments, the number of heat sinks is multiple. These multiple heat sinks are stacked. The stacking direction of the multiple heat sinks is perpendicular to the extending direction of the heat sinks.

Detailed Implementation

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or relative positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and for simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in practical applications, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0075] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0076] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0077] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0078] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0079] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0080] With the rapid development of vehicle electrification and intelligence, the types of vehicles are gradually increasing. For example, a vehicle can include three types of onboard electrical systems: electric drive system, power battery system, and electronic control system.

[0081] As is known, during vehicle operation, some of the vehicle's components generate heat, forming a heat source. For example, the vehicle's engine and electrical systems all generate heat during operation.

[0082] It is understandable that some components of a vehicle will generate a lot of heat when the vehicle is under certain extreme operating conditions. For example, when a vehicle is engaged in high-power operation such as continuous uphill climbing, off-road driving, or rally driving, the vehicle's engine will generate a large amount of heat.

[0083] To dissipate heat from the devices that generate heat in the vehicle, the vehicle may include a heat dissipation module. The heat dissipation module can carry away the heat generated by these devices, thus achieving a cooling effect.

[0084] In related technologies, a heat dissipation module may include a heat sink. A high-temperature liquid that has exchanged heat with the aforementioned heat source can circulate within the heat sink. For example... Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the heat dissipation principle of a heat dissipation module in related technologies. The liquid 011 inside the heat sink can exchange heat with the peripheral wall 012 of the heat sink, transferring heat to the peripheral wall 012. Then, the heat on the peripheral wall 012 is dissipated through contact with the ambient air.

[0085] Depend on Figure 1 It can be seen that heat exchange occurs between the liquid 011 and the peripheral wall 012 at a liquid-solid interface, resulting in good heat exchange performance due to low thermal resistance. However, heat exchange occurs between the heat sink 010 and the ambient air at a solid-gas interface, resulting in poor heat exchange performance due to high thermal resistance. Heat cannot be effectively transferred from the heat sink 010 to the air in a timely manner, leading to poor overall heat exchange performance of the heat exchange module. Furthermore, as the ambient air velocity increases, the heat exchange efficiency between the outside air and the heat sink 010 does not increase linearly, and the increase in heat exchange effect is not very significant.

[0086] Based on this, embodiments of this application provide a vehicle, the type of which is not specifically limited. For example, the vehicle can be a new energy vehicle or a gasoline-powered vehicle. Furthermore, the specific components of the vehicle are not specifically limited in embodiments of this application. For instance, to achieve vehicle propulsion, the vehicle may also include a drive system. The drive system provides power to the vehicle, enabling it to move.

[0087] In some embodiments, the vehicle may further include a battery system. The battery system provides electrical energy to the vehicle, powering other electrical components. Accordingly, the drive system may include an electric motor, which may be electrically connected to the battery system and operate using the electrical energy provided by the battery, thereby propelling the vehicle.

[0088] During vehicle operation, some components of the vehicle, such as the engine and electric motor, generate heat. Therefore, in order to dissipate heat from these components, the vehicle provided in this application embodiment may further include a cooling system. This cooling system can dissipate heat from the components in the vehicle that generate heat, thereby ensuring the normal operation of the vehicle.

[0089] like Figure 2 As shown, Figure 2 This is a schematic diagram of a heat dissipation system 100 provided in an embodiment of this application. The heat dissipation system 100 may include a heat exchange device 20 and a heat dissipation circuit 50. The two ends of the heat exchange device 20 may be connected to the heat dissipation circuit 50.

[0090] The cooling circuit 50 can carry a cooling medium (such as coolant), which can exchange heat with heat-generating devices in the vehicle. After heat exchange, the cooling medium can flow to the heat exchange device 20, where it exchanges heat with the outside air, thereby cooling the cooling medium and allowing it to be recycled.

[0091] Continue to refer to Figure 2 The heat dissipation system 100 may also include a heat dissipation device 10. The heat dissipation device 10 may also be connected to the heat exchange device 20. The heat dissipation device 10 can perform heat exchange and cooling on the material to be heat exchanged.

[0092] like Figure 2 As shown, in some embodiments, the heat dissipation system 100 may further include a heat exchange cooling circuit 30, and the heat dissipation device 10 may be connected to the circuit formed by the heat exchange cooling circuit 30 and the heat exchange device 20. In this case, two different cooling media may circulate within the heat exchange device 20.

[0093] For example, coolant can flow through the heat dissipation circuit 50, and cooling water can flow through the heat exchange cooling circuit 30. At this time, the cooling water can exchange heat with the coolant through the heat exchange device 20, thereby improving the cooling effect of the coolant. Then, the heat dissipation device 10 can cool the cooling water after the heat exchange, realizing the recycling of the cooling water.

[0094] First, the heat dissipation device 10 provided in the embodiments of this application will be further described, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of a heat dissipation device 10 provided in an embodiment of this application. The heat dissipation device 10 may include a mixing component 11. A heat exchange channel 111 is formed inside the mixing component 11, and the mixing component 11 is provided with a first inlet and a second inlet 112. The heat exchange channel 111 is connected to the first inlet and the second inlet 112. The first inlet is used to allow the material to be heat-exchanged to enter the heat exchange channel 111, and the second inlet 112 is used to introduce cooling gas, so as to achieve direct contact heat exchange between the material to be heat-exchanged and the cooling gas.

[0095] In this way, the material to be heat-exchanged enters the heat exchange channel 111 through the first inlet, and the cooling gas can enter the heat exchange channel 111 through the second inlet 112 to exchange heat with the material to be heat-exchanged in the heat exchange channel 111, thus removing the heat from the material. Since the material to be heat-exchanged directly contacts the cooling gas for heat exchange, the cooling efficiency is higher, ensuring the heat dissipation efficiency of the heat dissipation device 10.

[0096] In some embodiments, the heat exchange medium can be in a liquid state or a gas-liquid mixture state. For example, the heat exchange medium can be cooling water. When the heat exchange medium is in a gas-liquid mixture state, it can fully exchange heat with the cooling gas, resulting in better heat exchange performance.

[0097] Based on the above scheme, in practical applications, the heat exchange material flowing out of the heat exchange device 20 enters the heat exchange channel 111 in a gas-liquid mixed state. The cooling gas entering from the second inlet 112 is used to dissipate heat and cool down the cooling medium. The cooling medium that has cooled down to a liquid state can then be recycled.

[0098] In some embodiments, the mixing element 11 is further provided with an outlet. The heat exchange channel 111 is in communication with the outlet, which can be used to allow the hot gas after heat exchange and the cooled liquid to flow out.

[0099] In some embodiments, the outlet may include a first outlet 113 and a second outlet 114. The first outlet 113 may be used to allow the hot gas after heat exchange to flow out, and the second outlet 114 may be used to allow the cooled liquid to flow out.

[0100] For example, such as Figure 3 As shown, the mixing component 11 may have the aforementioned first outlet 113 and second outlet 114, i.e., the heat exchange channel 111 has the aforementioned first outlet 113 and second outlet 114. Alternatively, the mixing component 11 may also be connected to a pipeline, one end of which is connected to the heat exchange channel 111 of the mixing component 11, and the other end of which forms the aforementioned first outlet 113 and second outlet 114.

[0101] Of course, in some other embodiments, the heat exchange channel 111 may not be connected to the first outlet 113 and the second outlet 114. In this case, the cooled liquid and the hot gas after heat exchange can also flow out through the second inlet 112.

[0102] In some embodiments, such as Figure 4 As shown, Figure 4 for Figure 3The exploded view of the structure shown indicates that the heat dissipation device 10 may further include a flow guide 12. The flow guide 12 is connected to the mixing member 11 and is used to introduce the material to be heat exchanged into the heat exchange channel 111. Thus, the flow guide 12 can introduce external material to be heat exchanged into the heat exchange channel 111. Of course, in some other embodiments, the material to be heat exchanged may also directly enter the heat exchange channel 111 through the mixing member 11.

[0103] In some embodiments, such as Figure 5 As shown, Figure 5 This is a cross-sectional view of the flow guide 12 and the spray head 13 provided in the embodiments of this application. The flow guide 12 has a flow channel 121 inside, with one end extending into the heat exchange channel 111. Thus, the flow channel 121 inside the flow guide 12 can provide a flow channel for the external liquid, facilitating the introduction of the heat exchange medium.

[0104] In some embodiments, such as Figure 6 As shown, Figure 6 for Figure 5 The exploded view of the structure shown shows the flow guide 12 extending into the heat exchange channel 111. Figure 4 One end of the channel 111 has a flow port 122. Since the end of the channel 111 that extends into the heat exchange channel 111 has a flow port 122, the heat exchange material in the channel 121 can flow into the heat exchange channel 111 through the flow port 122.

[0105] In some embodiments, such as Figure 6 As shown, the heat dissipation device 10 also includes a spray head 13. The spray head 13 is disposed at the flow port 122 and covers the flow port 122. The spray head 13 is used to spray the material to be heat exchanged, so that the material to be heat exchanged becomes a gas-liquid mixture. Thus, the material to be heat exchanged in the flow channel 121 can pass through the spray head 13 to form a gas-liquid mixture, thereby enabling better heat exchange with the cooling gas and ensuring the heat exchange effect.

[0106] In some embodiments, such as Figure 6 As shown, the spray head 13 has a spray nozzle 131, which is connected to the first inlet. Thus, the liquid medium can be converted into a gas-liquid mixture to be exchanged through the spray nozzle 131. Of course, in some other embodiments, the first inlet on the mixing element 11 can also be sprayed. In this case, the liquid medium can directly pass through the first inlet on the mixing element 11 to form a gas-liquid mixture to be exchanged.

[0107] In some embodiments, such as Figure 5As shown, the drainage channel 121 includes a first drainage channel 1211 and a second drainage channel 1212. One end of the first drainage channel 1211 is connected to one end of the second drainage channel 1212, and the other end of the second drainage channel 1212 forms a flow opening 122. The extending direction of the first drainage channel 1211 intersects the extending direction of the second drainage channel 1212.

[0108] Thus, as Figure 6 and Figure 7 As shown, Figure 7 This is a schematic diagram of the heat exchange process between the heat exchange material and the cooling gas. When the liquid heat exchange material in the flow channel 121 enters the second flow channel 1212 from the first flow channel 1211, the heat exchange material can collide with the inner wall of the second flow channel 1212 and change direction, thereby forming turbulence. This makes the heat exchange material flow with a certain rotation when passing through the flow port 122, so that the heat exchange material can be more dispersed when it flows out.

[0109] In some embodiments, such as Figure 5 As shown, a blocking portion 1213 is formed within the second flow channel 1212. The blocking portion 1213 extends along the extension direction of the second flow channel 1212. In this way, the blocking portion 1213 can play a certain role in turbulence, making the flow path of the heat exchange material in the spray channel 2162 more complex, and making it more dispersed when entering the spray port 131 for spraying, thus achieving better spraying.

[0110] In some embodiments, along the extending direction of the blocking portion 1213, the cross-sectional area of ​​the blocking portion 1213 near the flow port 122 is smaller than the cross-sectional area of ​​the blocking portion 1213 away from the flow port 122. Thus, because the cross-sectional area of ​​the blocking portion 1213 near the flow port 122 is smaller, the flow velocity of the heat exchange material can be reduced when it flows to the end of the blocking portion 1213 near the flow port 122, thereby increasing the fluid pressure and improving the atomization effect.

[0111] In some embodiments, the cross-sectional area of ​​the blocking portion 1213 gradually decreases from the end of the blocking portion 1213 away from the flow port 122 to the end of the blocking portion 1213 closer to the flow port 122. In this way, when the heat exchange material flows along the periphery of the blocking portion 1213, it can better form turbulent vortices under the action of the blocking portion 1213, thereby achieving better spray flow.

[0112] In some embodiments, the blocking portion 1213 has a conical structure. In this case, the blocking portion 1213 can better serve its function of turbulence. Exemplarily, the blocking portion 1213 can be a conical structure or a pyramidal structure. Of course, the blocking portion 1213 can also be other shapes. For example, the blocking portion 1213 can also be a conical frustum or a pyramidal structure.

[0113] It is understood that the drainage component 12 can be connected to the mixing component 11 in different ways. For example, such as... Figure 3 As shown, the hybrid component 11 may have a protrusion 1152, the interior of which is hollow. For example... Figure 8 As shown, Figure 8 The cross-sectional view shows the mixing component 11 and the draining component 12 after installation. The draining component 12 can be located inside the protrusion 1152 and connected to the protrusion 1152. In this way, the installation between the draining component 12 and the mixing component 11 can be achieved through the protrusion 1152.

[0114] In some embodiments, the protrusion 1152 may be threadedly connected to the drainage member 12 to facilitate adjustment of the position of the drainage member 12. In this way, the position of the drainage member 12 can be adjusted by rotating the drainage member 12, making the position of the drainage member 12 more flexible.

[0115] In some embodiments, such as Figure 4 As shown, the mixing component 11 includes a first mixing component 115 and a second mixing component 116. A first heat exchange channel 1151 is formed inside the first mixing component 115. The second mixing component 116 is connected to the first mixing component 115 and has a second heat exchange channel 1161 formed inside, communicating with the first heat exchange channel 1151. The first heat exchange channel 1151 and the second heat exchange channel 1161 form the heat exchange channel 111.

[0116] In this way, the first heat exchange channel 1151 and the second heat exchange channel 1161 can each have different functions, making the heat exchange between the material to be exchanged and the cooling gas more convenient. For example, the first heat exchange channel 1151 can be used to exchange heat between the material to be exchanged and the cooling gas. The second heat exchange channel 1161 can be used to separate the cooled material to be exchanged from the hot air.

[0117] In some embodiments, the first hybrid component 115 and the second hybrid component 116 are detachably connected. This allows the first hybrid component 115 and the second hybrid component 116 to be manufactured separately, making manufacturing more convenient. Of course, the first hybrid component 115 and the second hybrid component 116 can also be manufactured as a single piece.

[0118] In some embodiments, such as Figure 4As shown, the second heat exchange channel 1161 includes a first sub-heat exchange channel 1162 and a second sub-heat exchange channel 1163. One end of the first sub-heat exchange channel 1162 is connected to the first heat exchange channel 1151 and extends in the same direction as the first heat exchange channel 1151. The other end of the first sub-heat exchange channel 1162 is connected between the two ends of the second sub-heat exchange channel 1163. The extension direction of the second sub-heat exchange channel 1163 intersects the extension direction of the first sub-heat exchange channel 1162, and a first outlet 113 and a second outlet 114 are formed at both ends, respectively. For example, in order to form the above-mentioned first sub-heat exchange channel 1162 and second sub-heat exchange channel 1163, the second mixing member 116 can be a T-shaped structure.

[0119] Therefore, the heat exchanged material and hot air can enter the second sub-heat exchange channel 1163 through the first sub-heat exchange channel 1162, and then flow to both ends of the second sub-heat exchange channel 1163 respectively, and flow out from both ends of the second sub-heat exchange channel 1163.

[0120] The heat exchange device 20 provided in the embodiments of this application will be further described below. Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of a heat exchange device 20 provided in an embodiment of this application. The heat exchange device 20 may include a heat sink 21. Wherein, as... Figure 10 As shown, Figure 10 for Figure 9 The diagram shows a partial structure of the heat exchange device 20. The heat sink 21 forms an independent main channel 211 and a heat dissipation channel 212. The main channel 211 and the heat dissipation channel 212 are used for heat exchange.

[0121] The two ends of the main channel 211 can be connected to the two ends of the heat dissipation circuit 50 respectively. In this way, after the coolant flowing in the heat dissipation circuit 50 exchanges heat with the heat source, it can flow into the main channel 211 of the heat sink 21, transfer the heat to the heat sink 21, and dissipate the heat through the contact between the heat sink 21 and the air.

[0122] The two ends of the heat dissipation channel 212 can be connected to the two ends of the heat exchange cooling circuit 30 respectively. In this way, the cooling water in the heat exchange cooling circuit 30 can flow into the heat dissipation channel 212 of the heat exchange device 20, and exchange heat with the coolant in the main channel 211 in the heat dissipation channel 212 to further cool the coolant and ensure the cooling effect.

[0123] For example, the heat dissipation channel 212 has a first end and a second end. The first end can be connected to the first inlet of the heat dissipation device 10 and then connected to the heat exchange cooling circuit 30 through the heat dissipation device 10. The second end is directly connected to the heat exchange cooling circuit 30. In this way, the cooling water in the heat dissipation channel 212 can enter the heat dissipation device 10 and be cooled down by the heat dissipation device 10.

[0124] Therefore, in the heat exchange device 20 provided in this embodiment, the main channel 211 can be circulated with a liquid medium (e.g., coolant) for exchanging heat with the heat source of the vehicle. When the liquid medium flows in the main channel 211, the heat of the liquid medium can be transferred to the heat exchange device 20. At this time, the external airflow can carry away the heat transferred to the heat exchange device 20. At the same time, the heat exchange channel 212 can circulate with a heat exchange medium (e.g., cooling water) that exchanges heat with the liquid medium. In this way, during the flow of the heat exchange medium in the heat exchange channel 212, the heat of the liquid medium can be directly transferred to the heat exchange medium through the heat exchange device 20, and the two can directly transfer heat, further improving the heat exchange efficiency of the heat exchange device 20, thereby improving the heat exchange efficiency of the liquid medium at the heat exchange device 20, and thus improving the heat exchange efficiency of the heat exchange device 20 for the heat-generating devices in the vehicle.

[0125] In some embodiments, along the arrangement direction of the heat dissipation channel 212 and the main channel 211, the size of the main channel 211 is larger than the size of the heat dissipation channel 212. Because the size of the main channel 211 is relatively larger than that of the heat dissipation channel 212, the flow rate of the coolant can be guaranteed, ensuring that enough coolant can flow through the heat sink 21 for heat exchange. Of course, in other embodiments, the size of the main channel 211 can also be equal to or smaller than the size of the heat dissipation channel 212, depending on the specific design requirements.

[0126] In some embodiments, such as Figure 10 As shown, there are multiple heat dissipation channels 212. Therefore, by setting multiple heat dissipation channels 212, the heat exchange medium in the multiple heat dissipation channels 212 can exchange heat with the heat sink 21, absorb the heat transferred by the liquid medium, and further improve the heat transfer effect of the liquid medium.

[0127] In some embodiments, a plurality of heat dissipation channels 212 are located around the main channel 211 along the extension direction of the main channel 211. In this way, the plurality of heat dissipation channels 212 can exchange heat with the main channel 211 from different positions around the main channel 211, thereby improving the heat exchange effect.

[0128] In some embodiments, such as Figure 10As shown, there are two heat dissipation channels 212, located on opposite sides of the main channel 211 along a first direction. The first direction is perpendicular to the extending direction of the main channel 211. This allows the heat dissipation channels 212 to exchange heat at different locations, ensuring effective heat exchange. Furthermore, the location of the two heat dissipation channels 212 on opposite sides of the main channel 211 reduces the size of the heat sink 21 in the direction perpendicular to the arrangement of the heat dissipation channels 212.

[0129] In some embodiments, such as Figure 10 As shown, the heat sink 21 may include a side plate 213 and a partition 214. The side plate 213 is annular, forming a flow channel. The partition 214 is disposed within the flow channel and connected to the side plate 213. The partition 214 extends along the extension direction of the flow channel, dividing the flow channel into a main channel 211 and a heat dissipation channel 212.

[0130] Therefore, by setting a partition 214 inside the side plate 213, the flow channel formed by the side plate 213 can be separated, forming the main channel 211 and the heat dissipation channel 212, resulting in a simple and convenient structure. For example, as shown... Figure 10 As shown, the side plate 213 can form a flat rectangular space, and the structure of the heat sink 21 is more regular.

[0131] As mentioned above, there can be multiple heat dissipation channels 212. Therefore, in order to form multiple heat dissipation channels 212, in some embodiments, there are multiple partitions 214. Multiple partitions 214 are arranged in parallel and spaced apart in the flow channel, dividing the flow channel into a main channel 211 and multiple heat dissipation channels 212. In this way, multiple heat dissipation channels 212 can be formed by multiple partitions 214.

[0132] In some embodiments, such as Figure 10 As shown, the heat exchange device 20 also includes a first heat dissipation fin 22. The first heat dissipation fin 22 is disposed within the first heat dissipation channel 212. Therefore, by providing the first heat dissipation fin 22, the contact area between the heat exchange medium and the heat exchange device 20 within the heat dissipation channel 212 can be increased, further improving the heat exchange effect of the heat exchange medium.

[0133] In some embodiments, the number of first heat dissipation fins 22 can be multiple. By providing multiple first heat dissipation fins 22, the heat dissipation effect of the heat sink 21 can be further improved.

[0134] In some embodiments, such as Figure 10As shown, the first heat dissipation fin 22 is disposed on the side wall of the heat dissipation channel 212 near the main channel 211. Therefore, the heat of the coolant in the main channel 211 can be better transferred to the first heat dissipation fin 22, thereby better dissipating heat from the coolant in the main channel 211.

[0135] In some embodiments, the first heat dissipation fins 22 extend along the extending direction of the heat dissipation channel 212. In this way, the first heat dissipation fins 22 can better contact the cooling water in the heat dissipation channel 212, and can better exchange heat during the flow of cooling water, thus ensuring the heat exchange effect.

[0136] In some embodiments, such as Figure 10 As shown, the heat exchange device 20 also includes a second heat dissipation fin 23. The second heat dissipation fin 23 is disposed on the outer wall of the heat dissipation component 21. Thus, by providing the second heat dissipation fin 23 on the outside of the heat dissipation component 21, the contact area between the air and the heat exchange device 20 can be increased, allowing the air to carry away more heat during the flow process, thereby improving the heat exchange effect.

[0137] In some embodiments, at least a portion of the second heat dissipation fins 23 are located on the outer wall of the main channel 211. In this way, the heat of the liquid medium inside the main channel 211 can be better transferred to the second heat dissipation fins 23, and the heat can be carried away from the second heat dissipation fins 23 by the flow of air, thereby improving the heat exchange effect between the liquid medium and the heat sink 21.

[0138] In some embodiments, a portion of the second heat dissipation fin 23 is located on the outer wall of the heat dissipation channel 212. In this way, the heat of the liquid medium inside the heat dissipation channel 212 can also be transferred to the second heat dissipation fin 23, and the heat can be carried away from the second heat dissipation fin 23 by the flowing air, thereby improving the heat exchange effect.

[0139] In some embodiments, the second heat dissipation fin 23 is perpendicular to the extending direction of the main channel 211. Thus, as shown in the figure, the second heat dissipation fin 23 can better contact the air flowing through the heat sink 21, ensuring effective heat dissipation.

[0140] In some embodiments, such as Figure 9 and Figure 11 As shown, Figure 11 This is a schematic diagram of the structure of a liquid distribution component 24 provided in an embodiment of this application. The heat exchange device 20 may also include multiple liquid distribution components 24. These components are distributed at both ends of the heat dissipation component 21 along its extension direction and are connected to the heat dissipation component 21. The liquid distribution components 24 are used to divert the medium within the main channel 211 and the heat dissipation channel 212. By providing these diversion components, the liquid medium can be diverted, allowing different liquid media to flow into or out of different locations.

[0141] In some embodiments, the dispensing component 24 has multiple independent dispensing chambers. Each dispensing chamber has a first dispensing port (not shown) and a second dispensing port 241. The opening of the main channel 211 can communicate with one of the first dispensing ports, and the opening of the heat dissipation channel 212 can communicate with the other first dispensing port. The second dispensing port 241 can be connected to a connecting pipe.

[0142] In this way, the liquid distribution component 24 can serve as a connector. The liquid medium and heat exchange medium flowing in the main channel 211 and the heat dissipation channel 212 respectively can flow into one of the liquid distribution chambers of the liquid distribution component 24, and can flow to other components through the second liquid distribution port 241.

[0143] For example, such as Figure 10 and Figure 11 As shown, the openings of the main channel 211 and the heat dissipation channel 212 can be rectangular. The second dispensing port 241 of the dispensing component 24 can be circular. This makes it easier to connect the second dispensing port 241 to the cylindrical pipeline.

[0144] The specific structure of the liquid distribution component 24 can be designed according to actual conditions. For example, such as... Figure 11 As shown, the liquid dispensing component 24 may include a first liquid dispensing section 242, a plurality of second liquid dispensing sections 243 and a plurality of third liquid dispensing sections 244.

[0145] The first dispensing section 242 can form multiple first dispensing ports at one end, and multiple independent chambers inside, and the first dispensing section 242 can be rectangular. In this way, the first dispensing section 242 can be easily connected with... Figure 3 The rectangular opening shown is connected.

[0146] Multiple second dispensing sections 243 are connected to the other end of the first dispensing section 242. Liquid in each independent chamber of the first dispensing section 242 can flow to the second dispensing sections 243. The second dispensing sections 243 can be frustum-shaped, and their bottoms are connected to the first dispensing section 242. Thus, as liquid flows from the first dispensing section 242 to the second dispensing section 243 and gradually flows out of the second dispensing section 243, the flow space decreases, allowing the flow velocity to gradually increase.

[0147] Multiple third dispensing sections 244 are each connected to the other end of a second dispensing section 243. Each third dispensing section 244 can be cylindrical, with one end forming the aforementioned second dispensing port 241. This allows the third dispensing section 244 to form a circular opening, facilitating connection to a cylindrical pipeline.

[0148] In some embodiments, such as Figure 9As shown, there are multiple heat sinks 21. These multiple heat sinks 21 are stacked. The stacking direction of the multiple heat sinks 21 is perpendicular to the extending direction of the heat sinks 21. Therefore, by using multiple heat sinks 21, the overall heat dissipation effect of the heat exchange device 20 can be improved.

[0149] In addition, such as Figure 9 As shown, to facilitate the flow of liquid within the multiple heat sinks 21, in some embodiments, the heat exchange device 20 may further include multiple liquid collectors 26. For example, Figure 12 As shown, Figure 12 This is a schematic diagram of the structure of a liquid collector 26 provided in an embodiment of this application. The liquid collector 26 may include multiple liquid collecting pipes 261 and a liquid collecting head 262. One end of each of the multiple liquid collecting pipes 261 can be connected to the liquid collecting head 262, and the other end can be connected to a second liquid distributing port 241 respectively. Figure 11 )connect.

[0150] Therefore, by using a liquid collector 26, the liquid medium in multiple main channels 211 can be collected together, or the heat exchange medium in multiple heat dissipation channels can be collected together. Then, it is only necessary to connect it to the other end of the liquid collector 262, which makes the connection more convenient.

[0151] In some embodiments, such as Figure 9 As shown, the heat exchange device 20 also includes a connector 25. The connector 25 is connected to multiple heat sinks 21. Thus, multiple heat sinks 21 can be connected together via the connector 25, making them a single unit for easy installation.

[0152] In some embodiments, such as Figure 13 As shown, Figure 13 This is a schematic diagram of the structure of a connector 25 provided in an embodiment of this application. The connector 25 may include a connecting body 251 and a plurality of connecting portions 252. The plurality of connecting portions 252 are spaced apart on the connecting body 251. One connecting portion 252 can connect to one heat sink 21 (…). Figure 9 )connect.

[0153] It is understandable that the connection method between the connecting part 252 and the heat sink 21 can be selected according to the actual situation. For example, the connecting part 252 can be welded to the heat sink 21. Alternatively, the connecting part 252 can also be bonded to the heat sink 21, as long as the connection between the two can be achieved.

[0154] As described above, the heat dissipation system 100 provided in this application embodiment includes a heat exchange cooling circuit 30. One end of the heat exchange cooling circuit 30 can be connected to an outlet, and the other end can be connected to the second end of the heat dissipation channel 212. For example, one end of the heat exchange cooling circuit 30 can be connected to the second outlet 114.

[0155] In this way, the heat exchange medium in the heat exchange cooling circuit 30 can be cooled by the heat dissipation device 10, allowing the heat exchange medium to be recycled. The heat exchange cooling circuit 30 provided in the embodiments of this application will now be described by way of example.

[0156] In some embodiments, such as Figure 2 As shown, the heat exchange cooling circuit 30 includes a first housing 31. The first housing 31 is connected to the second outlet 114 and to the second end of the heat dissipation channel 212. In this way, the first housing 31 can serve to store the heat exchange medium.

[0157] In some embodiments, the heat exchange cooling circuit 30 further includes a first pump body 32. The first pump body 32 is connected between the first housing 31 and the second end of the heat dissipation channel 212. In this way, the heat exchange medium in the first housing 31 can be drawn out by the pumping force of the first pump body 32 and flow into the heat exchange channel.

[0158] In some embodiments, the heat exchange cooling circuit 30 further includes a first control valve 33. One end of the first control valve 33 is connected to the first pump body 32, and the other end is connected to the second end of the heat dissipation channel 212. Thus, the flow of the heat exchange medium within the heat dissipation channel 212 can be controlled by the first control valve 33. When heat exchange is required, the first control valve 33 can be opened. When heat exchange is not required, the first control valve 33 can be closed.

[0159] In some embodiments, the heat exchange cooling circuit 30 further includes a first flow meter 34. The first flow meter 34 is disposed between the other end of the first control valve 33 and the second end of the heat dissipation channel 212. The flow rate can be monitored by the first flow meter 34 to ensure that a suitable flow rate of heat exchange medium flows within the heat dissipation channel 212.

[0160] In some embodiments, the heat exchange cooling circuit 30 further includes an adapter 35. The adapter 35 is used to connect the first flow meter 34 and the other end of the heat dissipation channel 212. The adapter 35 allows for the transfer of liquid media in the heat exchange cooling circuit 30, facilitating installation.

[0161] In some embodiments, the adapter 35 includes a first connector and a plurality of second connectors. The first connector is connected to a first flow meter 34, and one of the second connectors is connected to a second end of a heat dissipation channel 212. In this way, the adapter 35 can be used to split the flow, allowing the liquid medium to flow through the plurality of second connectors into different heat dissipation channels 212.

[0162] In some embodiments, the heat exchange cooling circuit 30 further includes a plurality of second control valves 36. One second control valve 36 is connected between a second connector and a second end of the heat dissipation channel 212. Thus, the flow of the liquid medium within the plurality of heat dissipation channels 212 can be controlled via the second control valves 36. When heat exchange of the liquid medium within the plurality of heat dissipation channels 212 is required, the plurality of second control valves 36 can be opened; when heat exchange of only one heat dissipation channel 212 is required, only one second control valve 36 can be opened.

[0163] In some embodiments, to improve the contact heat transfer effect between the heat exchanger and the air, the heat dissipation system 100 further includes a cooling fan 40. The cooling fan 40 is located on one side of the heat exchange device 20. In this way, the cooling fan 40 can accelerate the airflow near the surface of the heat exchange device 20, thereby improving the contact effect between the heat exchange device 20 and the air.

[0164] The heat dissipation circuit 50 provided in the embodiments of this application will be described in detail below.

[0165] In some embodiments, such as Figure 2 As shown, the heat dissipation circuit 50 includes a second housing 51. The two ends of the main channel 211 of the second housing 51 are connected. In this way, the second housing 51 can serve to store the heat exchange medium.

[0166] In some embodiments, the heat dissipation circuit 50 further includes a second pump body 52. ​​The second pump body 52 is connected between the second housing 51 and one end of the main channel 211. In this way, the heat exchange medium in the second housing 51 can be drawn out by the suction force of the second pump body 52 and flow into the main channel 211.

[0167] In some embodiments, the heat dissipation circuit 50 further includes a third control valve 53. One end of the third control valve 53 is connected to the second pump body 52, and the other end is connected to one end of the heat dissipation channel 212. Thus, the flow of the heat exchange medium in the main channel 211 can be controlled by the third control valve 53. When heat exchange is required, the third control valve 53 can be opened. When heat exchange is not required, the third control valve 53 can be closed.

[0168] In some embodiments, the heat dissipation circuit 50 further includes a second flow meter 54. The second flow meter 54 is disposed between the other end of the third control valve 53 and one end of the main channel 211. The flow rate can be monitored by the second flow meter 54 to ensure that a suitable flow rate of heat exchange medium flows in the main channel 211.

[0169] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
