[0036] When a vehicle is operating under high temperature conditions, the oil temperature in the fuel tank that supplies the engine is too high, which brings many potential safety hazards to the entire vehicle. Therefore, it is inevitable to set up a cooling component to cool the oil in the vehicle's fuel tank to ensure that the oil supplied to the engine does not exceed the safe temperature range, thereby ensuring the safety and reliability of the vehicle's high-temperature operation.

[0037] A common measure is to use a radiator to cool the oil in the fuel tank. However, the radiator in the related art has a simple structure and low heat dissipation effect, which cannot meet the engine's oil temperature requirements. To address the problem of low cooling effect of the radiator on the fuel tank in the related art, the present application provides a fuel tank cooling system and vehicle.

[0038] See Figure 1 As shown, Figure 1 This is a structural schematic diagram of a fuel tank cooling system 100 of the present application. The fuel tank cooling system 100 provided in the present application includes a fuel tank 3, a first cooling assembly 1 and a second cooling assembly 2, wherein the fuel tank 3 has an oil supply port 32 for supplying oil to the engine 4, that is, the oil in the fuel tank 3 flows to the engine 4 via the oil supply port 32 to supply oil to the engine 4, the first cooling assembly 1 includes a plurality of cooling elements 10, each cooling element 10 is provided on the fuel tank 3, and is used to dissipate heat from the fuel tank 3. Specifically, the plurality of cooling elements 10 absorb heat emitted from the fuel tank 3 so that the fuel tank 3 can dissipate heat, the second cooling assembly 2 includes a heat exchanger 22, one end of the heat exchanger 22 is connected to the oil supply port 32, and the other end is connected to the engine 4 to exchange heat for the oil flowing from the oil supply port 32 to the engine 4, that is, the oil in the fuel tank 3 flows out from the oil supply port 32, passes through the second cooling assembly 2 to dissipate heat, and then flows into the engine 4, so that the temperature of the oil flowing into the engine 4 does not exceed the safe temperature range.

[0039] The fuel tank cooling system 100 provided in the present application cools down the oil in the fuel tank 3 and the oil flowing from the fuel tank 3 to the engine 4 to ensure that the temperature of the oil flowing into the engine 4 does not exceed the safe temperature range. Specifically, the first cooling component 1 absorbs the heat of the oil in the fuel tank 3 through a plurality of cooling members 10 provided on the fuel tank 3, so that the fuel tank 3 is in a low-temperature working condition, thereby ensuring that the oil in the fuel tank 3 is cooled. The heat exchanger 22 of the second cooling component 2 is connected to the oil supply port 32 of the fuel tank 3 to cool the oil flowing from the fuel tank 3 to the engine 4, thereby ensuring that the temperature of the oil flowing into the vehicle engine 4 does not exceed the safe temperature range and meets the temperature requirement of the engine 4 for the oil.

[0040] Figure 3 This is a schematic diagram of the structure of the heat sink 10 in this application, see Figure 1 and Figure 3As shown, the heat sink 10 includes a plurality of heat dissipation nodes 11 arranged in sequence along the longitudinal direction of the oil tank 3, and each heat dissipation node 11 is provided with a heat dissipation channel for circulating circulating fluid, and the circulating fluid in the heat dissipation channel is used to exchange heat with the oil in the oil tank 3. It can be understood that the heat dissipation channels of the plurality of heat dissipation nodes 11 are connected in sequence along the longitudinal direction of the oil tank 3, and the circulating fluid flowing therein flows from the heat dissipation channel of the heat dissipation node 11 at one end along the longitudinal direction of the oil tank 3 to the heat dissipation channel of the heat dissipation node 11 at the other end. During the circulation of the circulating fluid in the heat dissipation channel, the circulating fluid absorbs the heat emitted by the oil tank 3, keeps the oil tank 3 in a low-temperature working state, and realizes cooling of the oil tank 3 and the oil in the oil tank 3.

[0041] Figure 4 This is a main view of the heat dissipation node 11 in the present application. Each heat dissipation node 11 includes multiple cooling tubes 111 and two collecting tubes 112 extending along the longitudinal direction of the oil tank 3. One end of the multiple cooling tubes 111 is connected in parallel to one of the collecting tubes 112, and the other end of the multiple cooling tubes 111 is connected in parallel to the other collecting tube 112. In this way, the cooling tubes 111 are connected to form a heat dissipation channel. It can be understood that the heat dissipation node 11 is composed of a modular structure through the layout of multiple parallel cooling tubes 111 and two collecting tubes 112 arranged at both ends of the cooling tubes 111. The parallel arrangement of multiple cooling tubes 111 expands the lateral extension area of ​​the heat dissipation node 11, thereby increasing the covering area of ​​the heat dissipation node 11 on the oil tank 3, so that the heat dissipation node 11 can more fully absorb the heat emitted by the oil tank 3 and cool the oil tank 3. The collecting tubes 112 at both ends of the cooling tube 111 have a larger diameter. The arrangement of the collecting tubes at both ends of the multiple cooling tubes 111 in the middle causes the circulating fluid in the heat dissipation node 11 to form diversion, collection and turbulence, so that the heat exchange between the internal circulating fluid and the external oil is more sufficient, thereby further ensuring that the circulating fluid more fully absorbs the heat emitted by the oil tank 3 and improves the cooling efficiency.

[0042] In some embodiments, multiple heat dissipation nodes 11 are detachably connected to each other. Specifically, two mutually connected converging pipes 112 on adjacent heat dissipation nodes 11 are detachably connected. When one of the multiple heat dissipation nodes 11 of the heat dissipation element 10 is damaged, the heat dissipation node 11 can be replaced with a new heat dissipation node 11 through the detachable setting of the two adjacent converging pipes 112, thereby avoiding the need to replace the entire heat dissipation element 10, thereby reducing losses and saving costs.

[0043] In some embodiments, the concentrating tube 112 can be configured as a straight or curved tube. Specifically, different concentrating tubes 112 can be selected based on the shape and structure of the fuel tank 3 to assemble two adjacent heat dissipation nodes 11, thereby meeting the cooling requirements of fuel tanks 3 of different shapes and structures. Optionally, the multiple heat dissipation nodes 11 are not limited to being welded together to form an integrated assembly.

[0044] Each cooling tube 111 includes a first tube 1111 connected to one of the focusing tubes 112, and a second tube 1112 connected to the first tube 1111 and the other focusing tube 112 respectively. The first tube 1111 and the second tube 1112 are arranged at an angle, and the opening direction of the angle formed is toward the longitudinal axis of the heat sink 10, and the connection between the first tube 1111 and the second tube 1112 is arranged in an arc shape. While increasing the lateral extension area of ​​the heat dissipation node 11, it reduces the impact of the circulating fluid on the connection between the first tube 1111 and the second tube 1112 when flowing in the cooling tube 111, thereby improving the practicality of the cooling tube 111.

[0045] See Figure 4 As shown, in some embodiments, the acute angle formed by the angle between the first pipe 1111 and the axis of the longitudinal direction of the heat sink 10 is 45°. While expanding the lateral expansion area of ​​the first pipe 1111 relative to the longitudinal direction of the heat sink 10, it is ensured that the connection curvature between the first pipe 1111 and the collecting pipe 112 connected thereto is gentle, that is, the first pipe 1111 and the collecting pipe 112 connected thereto are smoothly connected, avoiding impact damage to the first pipe 1111 and the collecting pipe 112 due to excessive curvature between the two when the circulating liquid flows through the first pipe 1111 and the collecting pipe 112. On the other hand, the angle formed by the first pipe 1111 and the second pipe 1112 can be set to 120°. At this time, the acute angle formed by the angle between the second pipe 1112 and the axis of the longitudinal direction of the heat sink 10 is 15°. It can be understood that the first pipe 1111 and the second pipe 1112 are relatively flat, while the second pipe 1112 and the flow-collecting pipe 112 connected thereto are relatively flat, so as to avoid damage to the pipe connection when the circulating liquid flows through the first pipe 1111, the second pipe 1112 and the flow-collecting pipe 112, or the pipe connection angle is not suitable to affect the circulation of the circulating liquid in the pipe, thereby reducing the heat dissipation efficiency.

[0046] Figure 5 This is a side view of the heat dissipation node 11 in the present application. In some embodiments, six cooling tubes 111 are provided, and the angle between two adjacent cooling tubes 111 is 60°, which relatively improves the connection strength of the cooling tubes 111 provided in parallel.

[0047] In some embodiments, see Figure 6 As shown, Figure 6This is a side view of multiple heat sinks 10 of the first heat sink assembly 1 in the present application, wherein nine heat sinks 10 are provided, and each three heat sinks 10 form a row, forming a total of three rows of spaced-apart heat sinks 10. Multiple layers of heat sinks 10 are provided on one side of the fuel tank 3 to ensure that a low-temperature working environment is provided for the fuel tank 3. It can be understood that different numbers and arrangements of heat sinks 10 can be provided according to the heat dissipation requirements of the fuel tank 3 to suit the heat dissipation requirements of the fuel tank 3 with different structures.

[0048] Continue reading Figure 1 As shown, the first heat dissipation component 1 includes a cooling component 12, and the cooling components 12 are respectively connected to the two ends of multiple heat dissipation elements 10, so that the circulating fluid flowing through the heat dissipation elements 10 can be cooled by the cooling component 12. The cooled circulating fluid flows to the heat dissipation element 10 located on one side of the oil tank 3 again, absorbs the heat emitted by the oil tank 3 and the oil in the oil tank 3, and cools the oil tank 3 and the oil in the oil tank 3. The circulating fluid after absorbing the heat flows to the cooling component 12 again and is cooled by the cooling component 12, thereby circulating.

[0049] The cooling assembly 12 includes a heat sink and a first refrigeration element. The heat sink has a heat dissipation cavity connected to the heat dissipation channel. The first refrigeration element is disposed on one side of the heat sink to dissipate heat from the circulating fluid flowing in the heat dissipation cavity, thereby cooling the circulating fluid and facilitating its reflow to the heat sink 10 to provide low-temperature circulating fluid to the oil tank 3, thereby cooling the oil in the oil tank 3. Optionally, the specific structure of the cooling assembly 12 may be the same as that of the second heat dissipation assembly 2.

[0050] In some embodiments, two liquid inlet pipes 7 are provided at both ends of multiple heat sinks 10 in parallel, and the liquid inlet pipes 7 form a liquid inlet cavity connected to the multiple heat sinks 10. It can be understood that the cooling component 12 is respectively connected to the liquid inlet cavities of the two liquid inlet pipes 7. The circulating liquid after cooling by the cooling component 12 flows to one of the two liquid inlet pipes 7, and flows to the multiple heat sinks 10 through the liquid inlet pipe 7. The circulating liquid flowing through the multiple heat sinks 10 flows into the other of the two liquid inlet pipes 7, and flows from the liquid inlet pipe 7 to the cooling component 12.

[0051] In some embodiments, the oil tank cooling system 100 further includes a positioning assembly 6 provided on the oil tank 3, the positioning assembly 6 including two positioning flanges 61 and two positioning baffles 62, wherein the two positioning flanges 61 are provided at both ends of the oil tank 3 in the longitudinal direction and are respectively connected to the two liquid inlet pipes 7 and the two ends of the oil tank 3, so as to fix one of the two liquid inlet pipes 7 to one end of the oil tank 3 and the other of the two liquid inlet pipes 7 to the other end of the oil tank 3. The two positioning baffles 62 are provided on the side wall of the oil tank 3 at intervals along the longitudinal direction of the oil tank 3, and the positioning baffles 62 are provided with through holes at intervals, through which a plurality of heat sinks 10 are fixed to the side wall of the oil tank 3 using bolt assemblies. The present application uses the positioning flanges 61 and the positioning baffles 62 to strengthen the connection between the heat sink 10 and the side wall of the oil tank 3, thereby preventing the heat sink 10 from being separated from the oil tank 3.

[0052] Figure 2 This is a schematic diagram of the structure of the heat exchanger 22 in this application, and is combined with reference to Figure 2 As shown, the second heat dissipation assembly 2 includes a second refrigeration component 21, which has a delivery channel for circulating refrigerant and a refrigerator for generating refrigerant. The output end of the refrigerator is connected to the delivery channel to deliver the generated refrigerant to the heat exchanger 22 through the delivery channel.

[0053] The heat exchanger 22 has a first heat exchange channel connected to the oil supply port 32, and a second heat exchange channel connected to the delivery channel. It can be understood that the oil flowing out of the oil supply port 32 flows through the first heat exchange channel, and the output end of the refrigerator is connected to the second heat exchange channel through the delivery channel, and the refrigerant generated in the refrigerator is transferred to the second heat exchange channel, so that the refrigerant flows through the second heat exchange channel. That is to say, the first heat exchange channel and the second heat exchange channel are used to cooperate to enable the oil flowing through the first heat exchange channel to exchange heat with the refrigerant flowing through the second heat exchange channel, thereby cooling the oil flowing through the first heat exchange channel.

[0054] In some embodiments, the refrigerator is configured as an air conditioning component, and the refrigerant is cold air generated by the air conditioning component. The cold air is transmitted to the second heat exchange channel through the delivery channel to cool the oil flowing in the first heat exchange channel.

[0055] In some embodiments, the second heat dissipation assembly 2 also includes an exhaust pipe provided at one end of the second heat exchange channel away from the second refrigeration component 21. The exhaust pipe is connected to the air in one direction. The cold air in the second heat exchange channel and the oil flowing out of the oil supply port 32 are heat exchanged in the heat exchanger 22 and then discharged into the air through the exhaust pipe.

[0056] See Figure 2As shown, the heat exchanger 22 includes a plurality of heat exchange elements 222 arranged in parallel, each heat exchange element 222 is provided with a first heat exchange channel, and a accommodating cavity 221 is formed inside the second heat exchange channel, wherein the plurality of heat exchange elements 222 are arranged in the accommodating cavity 221, that is, the plurality of first heat exchange channels are arranged in the accommodating cavity 221, and the cold air flowing through the second heat exchange channels flows through the accommodating cavity 221, providing a low-temperature environment for the plurality of first heat exchange channels, thereby cooling the oil flowing in the first heat exchange channels.

[0057] Specifically, the heat exchange element 222 is formed by a plurality of heat exchange sections arranged in sequence along the longitudinal direction of the accommodating cavity 221. It can be understood that the first heat exchange channel is composed of a plurality of cooling tubes 111 and a flow collecting tube 112 of the heat exchange section. The plurality of cooling tubes 111 are arranged in parallel at corresponding angles to each other, which increases the contact area between the first heat exchange channel and the cold air in the accommodating cavity 221, so that the oil circulating in the plurality of cooling tubes 111 is in more sufficient contact with the cold air, thereby improving the cooling effect. At the same time, combined with the cooling The acute angle formed by the first pipe 1111 of the temperature pipe 111 and the axis of the longitudinal direction of the heat sink 10 is 45°, and the angle formed by the first pipe 1111 and the second pipe 1112 of the cooling pipe 111 is 120°. It can be understood that this structural setting makes the corners between the focusing pipe 112, the first pipe 1111 and the second pipe 1112 relatively smooth, and the communication is smooth, avoiding the accumulation of oil and dirt after long-term use, which causes blockage of the first heat exchange channel.

[0058] See Figure 1 As shown, the oil tank cooling system 100 includes a sensor control component 5, which is respectively connected to the first refrigeration component and the second refrigeration component 21. On the one hand, it controls the operation of the first refrigeration component to dissipate heat for the circulating fluid flowing in the cooling cavity, and on the other hand, it controls the second refrigeration component 21 to output refrigerant to the second heat exchange channel.

[0059] Specifically, the sensing control assembly 5 includes a controller 51 and multiple temperature monitors 52 connected to the first refrigeration element and the second refrigeration element 21, respectively. One of the multiple temperature monitors 52 is located on the outer wall of the fuel tank 3 to monitor the temperature of the fuel tank 3. Another of the multiple temperature monitors 52 is located near one end of the pipeline connecting the engine 4 and the second radiator 2 to measure the temperature of the oil entering the engine 4. Another of the multiple temperature monitors 52 is located outside the vehicle's cab to detect the ambient temperature. When the controller 51 receives information that the temperature of the fuel tank 3, the temperature of the pipeline connecting the engine 4 and the second radiator 2, and the ambient temperature (specifically, the liquid or gas temperature detected by the above temperature monitors 52) are all higher than a preset value, the controller 51 controls the first and second refrigeration elements 21 to operate, thereby cooling the fuel tank 3, the oil in the fuel tank 3, and the oil flowing out of the outlet of the fuel tank 3.

[0060] In some embodiments, the preset value of the temperature can be set to 43°C. When the temperature detected by multiple temperature monitors 52 is higher than 43°C, the controller 51 controls the first refrigeration component and the second refrigeration component 21 to work. When the temperature detected by multiple temperature monitors 52 is lower than 43°C, the first refrigeration component and the second refrigeration component 21 do not work. The temperature monitors 52 at the temperature of the fuel tank 3, the pipes connecting the engine 4 and the second heat dissipation component 2, and the ambient temperature can also be set to have different temperature preset values, and the controller 51 can be set to control the first refrigeration component and the second refrigeration component 21 to work separately or simultaneously according to different temperature preset values ​​to meet the working requirements of the vehicle under different high temperature working conditions.

[0061] In some embodiments, the engine 4 includes an oil outlet pipe 41 connected to the inner cavity of the engine 4, and the other end of the oil outlet pipe 41 is connected to the oil supply port 32 of the fuel tank 3. After the engine 4 finishes working, excess oil flows back to the fuel tank 3 through the oil outlet pipe 41.

[0062] In some embodiments, an oil level sensor 31 is provided at the oil supply port 32 of the oil tank 3 for detecting whether the oil stored in the oil tank 3 is sufficient.

[0063] The present application also provides a vehicle, including the above-mentioned fuel tank cooling system 100. When the vehicle is running under high-temperature conditions, when the temperature detected by multiple temperature monitors 52 is higher than 43°C, the controller 51 controls the first refrigeration element and the second refrigeration element 21 to operate. At this time, the first refrigeration element dissipates heat for the circulating fluid circulating in the cooling box, and the cooled circulating fluid flows through the multiple heat sinks 10 of the first heat sink assembly 1 to cool the fuel tank 3 and the oil in the fuel tank 3. The second refrigeration element 21 transports refrigerant to the heat exchanger 22 through the delivery channel. The low-temperature refrigerant and the oil flowing from the fuel supply port 32 of the fuel tank 3 through the heat exchanger 22 and finally into the engine 4 are heat exchanged in the heat exchanger 22, thereby reducing the temperature of the oil flowing from the fuel supply port 32 of the fuel tank 3 to the engine 4, so that the oil in the vehicle fuel tank 3 and the engine 4 can be maintained at a normal operating temperature.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
