Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a cooling system and a vehicle. Background Technology

[0002] During vehicle operation, many components generate heat. For example, the engine produces a significant amount of heat during operation, requiring a cooling system to keep it cool and ensure it operates within a suitable temperature range. Similarly, with the increasing prevalence of electric vehicles, the battery generates substantial heat during driving and charging, especially in high summer temperatures and prolonged use. This excessive heat can degrade battery performance, affecting its lifespan and even impacting vehicle safety. Therefore, a cooling system is essential to prevent overheating risks. Thus, the cooling system plays a crucial role in vehicle safety. Utility Model Content

[0003] The purpose of this disclosure is to provide a cooling system and vehicle that can improve the accuracy of detecting the number of impurity particles in the coolant.

[0004] To achieve the above objectives, in a first aspect, this disclosure provides a cooling system, comprising:

[0005] A circulation loop is used to supply coolant flow to cool the first component;

[0006] A detection device is installed on the circulation loop to detect the number of impurity particles in the coolant. The inlet of the detection device is lower than the outlet of the detection device.

[0007] A filtration device is installed in the circulation loop to filter impurity particles in the coolant.

[0008] Optionally, the distance between the detection element and the outlet of the detection device is less than the distance between the detection element and the inlet of the detection device, wherein the detection element is used to detect the number of impurity particles in the coolant.

[0009] Optionally, the inlet of the filter device faces downwards.

[0010] Optionally, the filter device is disposed on the circulation loop outside the housing, the housing being a housing for accommodating the first component.

[0011] Optionally, the system further includes:

[0012] A control device is connected to the detection device;

[0013] The detection device is used to detect the number of impurity particles in the coolant upon receiving a detection command from the control device, and to send the detection result to the control device.

[0014] The control device is used to generate a prompt message based on the detection result, the prompt message being used to indicate whether the coolant needs to be replaced.

[0015] Optionally, the system further includes:

[0016] A pump, installed on the circulation loop and connected to the control device, is used to drive the flow of coolant in the circulation loop upon receiving a start command from the control device.

[0017] Optionally, the control device is configured to send the detection command to the detection device again when the first duration reaches a preset duration, wherein the first duration is the duration from the sending of the start command.

[0018] Optionally, the system further includes:

[0019] A prompting device, connected to the control device, is used to output the prompting information.

[0020] Optionally, the first component is a vehicle battery.

[0021] In a second aspect, this disclosure provides a vehicle including the cooling system provided in the first aspect of this disclosure.

[0022] Through the above technical solution, the detection device is set in the circulation loop to detect the number of impurity particles in the coolant, and the filtration device is set in the circulation loop to filter the impurity particles in the coolant. By simultaneously setting up the detection and filtration devices in the circulation loop, the filtration device can filter out as many impurity particles as possible that have already been counted by the detection device. When the coolant flowing out of the filtration device recirculates back to the detection device, it avoids the detection device from repeatedly counting the already counted impurity particles. Furthermore, the inlet of the detection device is lower than its outlet, meaning the coolant flows from bottom to top within the detection device. This prevents excessively fast coolant flow rates that could lead to missed detection of impurity particles, ensuring that all impurity particles are adequately detected. Moreover, as the coolant flows from bottom to top within the detection device, the shear force can suspend the impurity particles, causing them to float upwards and be discharged from the outlet with the flow of coolant. This prevents impurity particles from accumulating inside the detection device, avoiding the problem of detecting an excessive number of impurity particles and improving the accuracy of the detected number of impurity particles in the coolant.

[0023] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, the terms "first," "second," etc., are used to distinguish one element from another and are not of sequential or material importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The foregoing definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0031] Figure 1 This is a schematic diagram of a cooling system according to an exemplary embodiment, such as... Figure 1 As shown, the cooling system may include a circulation loop 11, a detection device 13, and a filter device 14.

[0032] The circulation loop 11 is used to supply coolant flow to cool the first component 12. For example, the first component 12 can be a vehicle battery or a vehicle engine, and this disclosure does not limit it. Figure 1 The direction indicated by the middle arrow is the direction of coolant flow. Figure 1The coolant flow direction shown is merely an example. The coolant composition is, for example, water and ethylene glycol. To ensure corrosion resistance and high temperature resistance, the circulation loop 11 can be made of aluminum or copper pipes, and the coolant can circulate in the circulation loop 11 to cool the first component 12.

[0033] The detection device 13 is installed on the circulation loop 11 and is used to detect the number of impurity particles in the coolant.

[0034] The detection device 13 is installed on the circulation loop 11, meaning that the detection device 13 is connected to the circulation loop 11. During use, the cooling system may experience impurity particles falling into the coolant due to reasons such as pipe aging and corrosion. These impurity particles may include, for example, metal impurity particles or iron filings. The detection device 13 can sense the impurity particles in the coolant through electromagnetic induction and detect the number of impurity particles.

[0035] In one embodiment, the inlet 131 of the detection device 13 is lower than the outlet 132 of the detection device 13.

[0036] Among them, such as Figure 1 As shown, the detection device 13 has a pipe 133 for supplying coolant flow. The pipe 133 can be connected to the pipe of the circulation loop 11, for example, by a threaded connection. One end of the pipe 133 can be used as the inlet 131 of the detection device 13, and the other end of the pipe 133 can be used as the outlet 132 of the detection device 13. The coolant flows from bottom to top in the pipe 133.

[0037] In this design, the inlet 131 of the detection device 13 is lower than the outlet 132. Compared to the case where the inlet 131 and outlet 132 are at the same height (i.e., the coolant flows horizontally) and the case where the inlet 131 is higher than the outlet 132 (i.e., the coolant flows from top to bottom), the upward flow of coolant within the detection device 13 can slow down the flow rate to some extent. This prevents the coolant from flowing too fast and thus avoiding the missed detection of impurity particles, ensuring that impurity particles are fully detected. Secondly, since air bubbles are less dense than liquids, they will naturally rise. With the outlet 132 higher than the inlet 131, if air bubbles exist in the pipe 133, the outlet 132's position allows the bubbles to escape smoothly. The bubbles can rise with the flow of coolant and exit from the outlet 132. Furthermore, when the coolant flows from bottom to top within the detection device 13, the shear force can cause impurity particles to suspend, causing them to float upwards and be discharged from the outlet 132 along with the flow of the coolant. This prevents impurity particles from accumulating inside the detection device 13 and avoids the problem of an excessively large number of impurity particles detected due to their accumulation inside the detection device 13, resulting in inaccurate detection results.

[0038] In one embodiment, the distance between the detection element 134 in the detection device 13 and the liquid outlet 132 of the detection device 13 is less than the distance between the detection element 134 and the liquid inlet 131 of the detection device 13, wherein the detection element 134 is used to detect the number of impurity particles in the coolant.

[0039] The distance between the detection element 134 and the outlet 132 can refer to the distance between the center of the detection element 134 and the outlet 132, and the distance between the detection element 134 and the inlet 131 can refer to the distance between the center of the detection element 134 and the inlet 131. For example... Figure 1 As shown, the distance between the detection element 134 and the outlet 132 is less than the distance between the detection element 134 and the inlet 131, meaning the detection element 134 is positioned closer to the outlet 132. If the detection element 134 is relatively small, it can be placed inside the pipe 133. In this case, the detection element 134 will not affect or obstruct the flow of coolant within the pipe 133, and it will not be washed away by the flow of coolant. The detection element 134 can also be connected within the pipe 133. Figure 1 The dimensions of the detection element 134 shown are for illustrative purposes only and can be adjusted according to actual needs.

[0040] For example, the detection element 134 can be a metal particle sensor, which uses the principle of electromagnetic induction to detect the number of metal particles in the coolant. Alternatively, the detection element 134 can be a high-precision laser sensor, which can detect the number and size distribution of impurity particles in the coolant. During coolant flow, suspended impurity particles in the coolant can block the laser beam or light source, causing changes in light intensity. The laser sensor can detect these changes in light intensity, thereby detecting the number of impurity particles in the coolant.

[0041] The detection element 134 is positioned near the outlet 132. As the coolant flows upward within the detection device 13, the shear force can suspend impurity particles, causing them to float upward and not accumulate at the bottom of the pipe 133. Therefore, positioning the detection element 134 near the outlet 132 allows it to fully detect the suspended impurity particles. Furthermore, the relatively slow flow velocity near the outlet 132 also allows the detection element 134 to fully detect the impurity particles, avoiding missed detections due to excessively high flow rates. This improves the accuracy of the detected number of impurity particles in the coolant.

[0042] The filter device 14 is installed on the circulation loop 11 and is used to filter impurity particles in the coolant.

[0043] The filter device 14 is installed on the circulation loop 11, meaning that the filter device 14 is connected to the circulation loop 11. When the detection device 13 detects the number of impurity particles in the coolant, it accumulates the results of multiple detections. For example, if the number of impurity particles detected in the coolant is n in the first detection and m in the second detection, then the detection result is considered to be the number of impurity particles in the coolant as n+m.

[0044] To avoid the detection device 13 repeatedly counting impurity particles, a filter device 14 can be installed in the circulation loop 11. The filter device 14 can be used to filter impurity particles in the coolant. Thus, as... Figure 1 As shown, the coolant flows through the detection device 13, which detects the number of impurity particles in the coolant. Then, when the coolant flows through the filter device 14, the filter device 14 can filter out as many impurity particles as possible that have already been counted by the detection device 13. In this way, when the coolant flowing out of the filter device 14 recirculates back to the detection device 13, it can avoid the detection device 13 from repeatedly counting the already counted impurity particles. To a certain extent, this can avoid the problem of the detection device 13 outputting an excessive number of impurity particles, thus improving the accuracy of the detection results.

[0045] This disclosure does not limit the filtration method. For example, the filtration device 14 may be equipped with a sintered filter element, which can filter impurity particles with a diameter greater than 250 μm.

[0046] Through the above technical solution, the detection device is set in the circulation loop to detect the number of impurity particles in the coolant, and the filtration device is set in the circulation loop to filter the impurity particles in the coolant. By simultaneously setting up the detection and filtration devices in the circulation loop, the filtration device can filter out as many impurity particles as possible that have already been counted by the detection device. When the coolant flowing out of the filtration device recirculates back to the detection device, it avoids the detection device from repeatedly counting the already counted impurity particles. Furthermore, the inlet of the detection device is lower than its outlet, meaning the coolant flows from bottom to top within the detection device. This prevents excessively fast coolant flow rates that could lead to missed detection of impurity particles, ensuring that all impurity particles are adequately detected. Moreover, as the coolant flows from bottom to top within the detection device, the shear force can suspend the impurity particles, causing them to float upwards and be discharged from the outlet with the flow of coolant. This prevents impurity particles from accumulating inside the detection device, avoiding the problem of detecting an excessive number of impurity particles and improving the accuracy of the detected number of impurity particles in the coolant.

[0047] In one embodiment, the inlet 141 of the filter device 14 faces downwards, which can be understood as vertically downwards. For example... Figure 1 As shown in the diagram, the dashed lines in the filter device 14 represent the piping used for supplying coolant flow within the filter device 14. Figure 1 The configuration of the pipeline shown is merely an example. For example, a filter element can be installed in the pipeline. The pipeline of the circulation loop 11 can be connected to the pipeline, for example, by a threaded connection. One end of the pipeline can serve as the inlet 141 of the filter device 14, and the other end of the pipeline can serve as the outlet 142 of the filter device 14.

[0048] The inlet 141 of the filter device 14 faces downwards, allowing impurities in the coolant to be deposited in the filter element under gravity and thus filtered out by the filter device 14. This prevents impurities from falling back into the circulation loop 11, causing the detection device 13 to repeatedly count impurities, improving the filtration effect and the accuracy of impurity detection results. The opening direction of the outlet 142 of the filter device 14 is not restricted; the outlet 142 simply needs to be connected to the circulation loop 11 to allow the coolant to flow smoothly into the circulation loop 11. Figure 1 The opening direction of the liquid outlet 142 shown is horizontal to the right, which is only an example and is not intended to limit the embodiments of this disclosure. The opening direction of the liquid outlet 142 of the filter device 14 can vary depending on the position of the filter device 14 in the circulation loop 11, to ensure that the opening direction of the liquid inlet 141 is downward, so as to avoid impurity particles falling back into the circulation loop 11 as much as possible.

[0049] In one embodiment, the filter device 14 is disposed on the circulation loop 11 outside the housing 15, which is a housing for accommodating the first component 12.

[0050] Figure 2 This is a schematic diagram of a cooling system according to another exemplary embodiment, such as... Figure 2 As shown, the circulation loop 11 may include a first coolant pipe 111 and a second coolant pipe 112. The first coolant pipe 111 is disposed inside the housing 15, and the second coolant pipe 112 is disposed outside the housing 15. The first coolant pipe 111 shown in the figure has a curved shape, which is only a preferred example. This can increase the contact area with the first component 12, thereby removing more heat generated by the first component 12 and improving the cooling effect. However, this disclosure does not limit the shape of the first coolant pipe 111 and the second coolant pipe 112.

[0051] To facilitate the replacement of the filter device 14, the filter device 14 can be installed on the circulation loop 11 outside the housing 15, so that the filter device 14 can be replaced without opening the housing 15. The circulation loop 11 outside the housing 15 is also the second coolant line 112.

[0052] like Figure 2 As shown, a detection device 13 is installed on the first coolant pipe 111. Following the coolant flow direction, a filter device 14, a pump 17, and a coolant reservoir 19 are sequentially installed on the second coolant pipe 112. The coolant reservoir 19 serves as a coolant storage device. Since the coolant expands when the temperature rises, the reservoir 19 can accommodate the expanded coolant and also helps relieve pressure in the circulation loop 11. The pump 17 can be a water pump, used to drive the coolant flow in the circulation loop 11, providing power for the coolant flow. The detection device 13 is installed on the circulation loop 11 inside the housing 15. This is merely an example; taking the first component 12 as a vehicle battery as an example, in this example, the detection device 13 can be integrated with the vehicle battery pack, thus eliminating the need for the user to install an additional detection device 13. However, this disclosure does not limit the placement of the detection device 13; for example, the detection device 13 can also be installed on the circulation loop 11 outside the housing 15.

[0053] The housing 15 has a first boss 20 and a second boss 21, which can be integrally cast with the housing 15. The inner wall of the first boss 20 may be threaded, allowing a water nozzle to be connected to it. The first end of the first coolant pipe 111 and the first end of the second coolant pipe 112 can be connected to the water nozzle, thus connecting the first ends of the first coolant pipe 111 and the second coolant pipe 112. Similarly, the inner wall of the second boss 21 may be threaded, allowing a water nozzle to be connected to it. The second end of the first coolant pipe 111 and the second end of the second coolant pipe 112 can be connected to the water nozzle, thus connecting the second ends of the first coolant pipe 111 and the second coolant pipe 112. This integrates the circulation loop 11 with the housing 15 and ensures the continuity of the circulation loop 11.

[0054] In one embodiment, the cooling system may further include a control device 16, which is connected to the detection device 13 and the pump 17. For example, the control device 16 may be a vehicle controller or a cooling system controller.

[0055] In one embodiment, the cooling system may further include:

[0056] Pump 17 is installed on the circulation loop 11 and connected to the control device 16. Pump 17 is used to drive the flow of coolant in the circulation loop 11 when a start command is sent by the control device 16.

[0057] For example, pump 17, as a power unit in circulation loop 11, can be a water pump or a gear pump with an internal motor. Pump 17 is powered by an on-board 12V / 24V DC power supply. Control device 16 can send a start command to pump 17, such as a command to close the relay of pump 17. Upon receiving the start command, pump 17 begins to operate, pumping coolant into circulation loop 11 and driving the flow of coolant in circulation loop 11. Control device 16 can send a stop command to pump 17. Upon receiving the stop command, pump 17 stops operating and stops driving the flow of coolant in circulation loop 11.

[0058] The control device 16 can send a detection command to the detection device 13. Upon receiving the detection command from the control device 16, the detection device 13 detects the number of impurity particles in the coolant and sends the detection result back to the control device 16. This detection result is the number of impurity particles in the portion of coolant currently flowing through the detection device 13, detected by the detection device 13 when it receives the detection command. The detection element 134 can transmit the detected number of impurity particles in the coolant to the signal transmission module of the detection device 13, which then sends the detection result to the control device 16.

[0059] As an example, a button for detecting coolant cleanliness can be installed in the vehicle. When the user triggers the button, the control device 16 can receive the detection request input by the user. The control device 16 can first send a clearing command to the detection device 13. The clearing command is used to instruct the detection device 13 to clear the historical detection data of impurity particles currently stored, that is, to clear the data to zero.

[0060] Subsequently, after the control device 16 sends a clearing command to the detection device 13, if the control device 16 does not receive a response message from the detection device 13 within a certain period of time, it can be determined that the current working state of the detection device 13 is abnormal. In this case, on the one hand, the control device 16 can send information indicating that the detection device 13 is abnormal to the prompting device 18, and the prompting device 18 can output this information, so that the user is aware that the detection device 13 is currently unable to work normally. On the other hand, the control device 16 can send a start command to the pump 17, and the pump 17 drives the coolant to circulate, and the cooling system plays the role of cooling the first component 12 and filtering the coolant.

[0061] If the control device 16 receives a response message from the detection device 13 within a certain time period, it can determine that the current working state of the detection device 13 is normal. The control device 16 can send a start command to the pump 17. The control device 16 is used to send a detection command to the detection device 13 after the first time period has reached a preset time period. The first time period is the time from sending the start command. The preset time period is, for example, 2 minutes. In this way, after the first time period reaches the preset time period, the distribution of impurity particles in the coolant in the circulation loop 11 is more uniform, which can make the number of detected impurity particles more accurate.

[0062] The control device 16 is used to generate a prompt message based on the detection results, which indicates whether the coolant needs to be replaced.

[0063] For example, if the control device 16 sends a detection command to the detection device 13, the control device 16 can receive the detection result sent by the detection device 13. The control device 16 can pre-store a quantity threshold. If the detection result is greater than the quantity threshold, a prompt message indicating that the coolant needs to be replaced can be generated. This prompt message can also prompt the user to replace the filter device 14. If the detection result is less than or equal to the quantity threshold, a prompt message indicating that the coolant does not need to be replaced can be generated.

[0064] For example, the control device 16 can send detection commands to the detection device 13 multiple times and receive the detection results sent by the detection device 13 each time. The control device 16 can, for example, fuse the multiple detection results, such as by averaging, to obtain the target detection result and compare the target detection result with the quantity threshold.

[0065] In one embodiment, the cooling system may further include:

[0066] The prompting device 18 is connected to the control device 16 and is used to output prompting information.

[0067] For example, the prompting device 18 may be a display screen installed in the vehicle, on which the prompting information can be displayed. The prompting device 18 may also be a voice playback device installed in the vehicle, on which the prompting information can be played. The prompting device 18 may also include a display screen and a voice playback device, and the prompting information can be output by displaying on the display screen and playing on the voice playback device at the same time.

[0068] For example, the control device 16 and the detection device 13, the control device 16 and the pump 17, and the control device 16 and the prompting device 18 can transmit signals through in-vehicle communication technology, such as through the vehicle CAN (Controller Area Network) bus or through a differential signal conversion module.

[0069] If the coolant contains a large number of impurities, it will affect the cooling effect on the first component 12, thus requiring coolant replacement at the appropriate time. If the user is left to determine when to replace the coolant, it often leads to indiscriminate replacement. For example, replacing the coolant when its cleanliness meets the standard increases costs, while failing to replace it when its cleanliness is insufficient will affect the heat dissipation efficiency of vehicle components. The above technical solution uses a detection device 13 to detect the number of impurities in the coolant. The control device 16 can determine whether the coolant needs to be replaced based on the detection results and output a prompt message through a prompt device 18, informing the user whether coolant replacement is necessary and avoiding premature replacement that leads to waste or delayed replacement that could pose safety hazards.

[0070] For example, the first component 12 can be a vehicle battery. (e.g.) Figure 1 and Figure 2 As shown, the housing 15 can be the battery pack housing of the vehicle battery. The first coolant pipe 111 can be laid flat inside the battery pack, and its laying height can be adaptively adjusted according to the inlet 131 and outlet 132 of the detection device 13. For example, the plane where the pipe of the circulation loop 11 connected to the inlet 131 is located is lower than the plane where the pipe of the circulation loop 11 connected to the outlet 132 is located. The second coolant pipe 112, which is located outside the housing 15, can also be laid flat inside the vehicle.

[0071] This disclosure also provides a vehicle that includes the cooling system provided in any of the above embodiments.

[0072] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0073] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0074] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
