For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] A thermal management module 100 , a thermal management system 1000 , and a vehicle 10000 according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0038] According to the thermal management module 100 of the first embodiment of the utility model, refer to Figure 1 , including: a refrigerant side component 20, a water side component 30 and a fire protection device 50, and the water side component 30 is connected to the refrigerant side component 20.

[0039] The refrigerant side component 20 belongs to the main structure of the thermal management module 100. The refrigerant side component 20 is used to construct the refrigerant circulation system of the thermal management module 100. The refrigerant side component 20 includes a compressor, a heat exchanger component and a throttling element that form a refrigerant circulation loop. The main structure of the thermal management module 100 may also include a water side component 30. The water side component 30 is used to construct the water circulation system of the thermal management module 100. The water side component 30 includes a water circuit heat exchanger. The water side component 30 may also include a water pump, a water tank, etc. The specific structure of the water side component 30 is not limited here. A part of the water circuit of the water side component 30 is in contact with the refrigerant heat exchanger component, which is used to absorb the cold or heat of the heat exchanger component. Another part of the water circuit of the water side component 30 is used for output, which can be arranged at a location where cooling or heating is required, and is used for heat dissipation and cooling or heating and temperature adjustment.

[0040] Specifically, the thermal management module 100 also includes a vibration isolation support assembly for supporting the main body structure and reducing vibration and noise transmitted outward. In some specific embodiments, the thermal management module 100 is a non-compact structure, that is, the refrigerant side assembly 20 and the water side assembly 30 are separately arranged. At this time, a vibration isolation support assembly is connected to the refrigerant side assembly 20 to reduce the outward vibration propagation of components such as the compressor. A vibration isolation support assembly may also be connected to the water side assembly 30 to reduce the outward vibration propagation of components such as the water pump. In other specific embodiments, the thermal management module 100 is a compact structure, and the refrigerant side assembly 20 and the water side assembly 30 are connected to form a whole. At this time, a vibration isolation support assembly is connected to at least one of the refrigerant side assembly 20 and the water side assembly 30.

[0041] It is understandable that the refrigerant in the refrigerant circulation system has a risk of leakage. When the leakage is small, the leaked refrigerant can usually be diluted and taken out by air flow, but in the event of an accident such as a collision, the refrigerant is discharged rapidly and the leakage is large, which will bring unnecessary safety risks. For example, the refrigerant used in some thermal management modules 100 is a flammable substance (such as propane R290 refrigerant). If an accident causes the flammable refrigerant to leak and encounter a fire source, the thermal management module 100 is likely to ignite quickly or even explode.

[0042] Since the refrigerant circulation system in the thermal management module 100 is mainly constructed by the refrigerant side component 20, the probability of refrigerant leakage from the refrigerant side component 20 is the highest in the event of an accident. Therefore, the fire protection device 50 provided in the present invention is mainly aimed at the refrigerant leakage problem of the refrigerant side component 20.

[0043] Reference Figure 1The fire prevention device 50 includes a fire extinguishing agent container 51 and a control switch 53. The fire extinguishing agent container 51 has a nozzle 511. The control switch 53 is used to control the opening and closing of the nozzle 511. The nozzle 511 is adjacent to the refrigerant side component 20 or is arranged on the refrigerant side component 20. The nozzle 511 is used to spray the fire extinguishing agent. The nozzle 511 can cover the fire extinguishing agent on the refrigerant side component 20, that is, after the surface of the refrigerant side component 20 is sprayed with the fire extinguishing agent, the leakage of the refrigerant can be reduced, which is conducive to isolating the refrigerant from the external air (mainly the fire source). Or the nozzle 511 can surround the fire extinguishing agent around the refrigerant side component 20, which is also conducive to isolating the refrigerant from the external air (mainly the fire source). Or the fire extinguishing agent sprayed from the nozzle 511 is partially covered on the surface of the refrigerant side component 20 and partially surrounded around the refrigerant side component 20, which not only reduces the leakage of the refrigerant, but also helps to isolate the refrigerant from the external air (mainly the fire source). The sprayed fire extinguishing agent can cover the leakage point to block the flow of refrigerant, or cover the flammable point to block contact with the air, or it can quickly fill around the refrigerant side component 20 to achieve the purpose of compressing the combustion space.

[0044] It should be noted that the thermal management module 100 provided with the fire prevention device 50 of the present invention is not limited to the use of flammable refrigerants, and the thermal management modules 100 of other types of refrigerants can also be provided with the fire prevention device 50. For example, when the refrigerant uses R744 refrigerant, the volume expands rapidly after leakage and easily forms a shock wave. At this time, a fire prevention device 50 can be provided to cover the surface of the refrigerant side component 20 with a fire extinguishing agent to block the leakage of the R744 refrigerant and reduce the generation of shock waves. The present invention adopts a fire prevention device 50 to use a fire extinguishing agent to protect the refrigerant side component 20. The fire prevention device 50 itself is non-flammable and can react quickly, so that the thermal management module 100 can cover or surround the refrigerant side component 20 with a fire extinguishing agent in time when encountering dangerous situations or unexpected situations. In this way, the combustion risk or impact risk of the thermal management module 100 can be reduced to protect the safety of personnel.

[0045] The protection scheme using the fire protection device 50 of the utility model is not only simple in structure and easy to implement, but also does not increase the cost and complexity of the thermal management module 100. The fire extinguishing agent can cover the entire refrigerant side component 20 as much as possible, so no matter where the fire occurs, the fire source can be effectively extinguished, which has strong adaptability.

[0046] In the solution of the present utility model, the fire extinguishing agent container 51 has a wide range of options for the types of fire extinguishing agents stored therein.

[0047] Optionally, the fire extinguishing agent may be a non-flammable gas fire extinguishing agent, which may specifically include but is not limited to: carbon dioxide, nitrogen, or inert gas, etc. The use of a gas fire extinguishing agent can quickly fill the surrounding air after being released, dilute the refrigerant concentration in the air within a certain period of time, and also play a role in isolating the fire source from the refrigerant.

[0048] Optionally, the fire extinguishing agent can be a non-combustible foam fire extinguishing agent. Optionally, the fire extinguishing agent can be a non-combustible solid fire extinguishing agent, such as powder or the like.

[0049] Specifically, the fire extinguishing agent can be one of the above types, or two or more of the above types. For example, multiple storage chambers are formed in the fire extinguishing agent container 51, and different types of fire extinguishing agents are stored in different storage chambers. Combined fire extinguishing agents are used to realize combined means to extinguish fires and flame retardant.

[0050] More specifically, whether using gas, foam or solid fire extinguishing agents, the fire extinguishing agents should preferably be environmentally friendly, non-toxic, non-flammable and non-conductive, so as to effectively extinguish the fire source while avoiding affecting the use of other external electrical appliances and avoiding harm to the environment and human body.

[0051] Of course, in order to suit the type of fire extinguishing agent, in some embodiments, the thermal management module 100 may be designed with an avoidance structure so as not to block the release of the fire extinguishing gas or fire extinguishing agent, thereby facilitating covering possible leakage points or flammable points on the refrigerant side component 20 .

[0052] The position of the nozzle 511 of the fire extinguishing agent container 51 should also ensure that when the fire extinguishing agent is sprayed, the fire extinguishing agent can cover the entire refrigerant side component 20. The release channel of the fire extinguishing agent container 51 can smoothly release compressed gas, foam or powdered fire extinguishing agent to ensure that any possible fire point above the refrigerant side component 20 can be effectively extinguished.

[0053] In some embodiments, the internal air pressure of the fire extinguishing agent container 51 is greater than the external air pressure of the refrigerant side assembly 20. Thus, when the control switch 53 is turned on, the fire extinguishing agent container 51 sprays the fire extinguishing agent through the pressure difference, thereby achieving rapid spraying of the fire extinguishing agent and improving the reaction sensitivity.

[0054] Of course, the solution of the present invention is not limited thereto, and in some embodiments, a driving pump may be used to spray the fire extinguishing agent in the fire extinguishing agent container 51 .

[0055] In the solution of the utility model, the specific structure of the control switch 53 can be selected according to the actual application scenario. For example, the control switch 53 can be a solenoid valve, which controls the switch by receiving an electrical signal. When using a solenoid valve, it opens quickly after receiving a signal, and the delay time is short. In particular, after receiving a collision signal or a fire signal, the solenoid valve opens quickly, and the fire extinguishing agent can be sprayed out in the first time to isolate the refrigerant that may leak. Even if the refrigerant catches fire, it can be extinguished in the first time, avoiding delaying the best time for fire extinguishing.

[0056] Optionally, the control switch 53 is a solenoid valve, and the response time is less than 0.1 seconds, so as to release the fire extinguishing agent in time. The solenoid valve has high sensitivity and fast response characteristics, and can be quickly opened after receiving an opening signal (such as a collision signal or high temperature information).

[0057] The opening time of the solenoid valve is a quick response, but it can also be adjusted according to actual needs to ensure that the fire extinguishing agent is released at the most appropriate time, thereby extinguishing the fire more effectively.

[0058] The solenoid valve can be replaced by a temperature control switch, which can be directly activated after detecting high temperature without going through the body controller or other safety systems.

[0059] In some embodiments, the thermal management module 100 further includes a detection sensor 55 electrically connected to the control switch 53, and the control switch 53 is controlled to open or close according to the detection result of the detection sensor 55. That is, the detection sensor 55 detects specific parameters and controls the control switch 53 to open or close when it determines danger according to the detection result.

[0060] That is to say, the thermal management module 100 has the ability to detect crises by setting up the detection sensor 55, and then quickly controls the fire prevention device 50 to start. In this way, not only the reaction sensitivity can be guaranteed, but also the position of the detection sensor 55 can be reasonably set according to the characteristics of the thermal management module 100 itself, such as being set at the point where the refrigerant is most likely to leak, or at the point where it is most likely to ignite, so that the safety and reliability are higher.

[0061] Optionally, the detection sensor 55 may be a temperature sensor, a concentration detection element, or other types of sensors.

[0062] Further optionally, the detection sensor 55 may be at least two sensors for detecting the danger level at different positions. In some schemes, the fire extinguishing agent container 51 has at least two nozzles 511, and the injection flow rates of different nozzles 511 are different. The injection flow rate ratio of different nozzles 511 can be adjusted according to the detection results of different sensors.

[0063] Of course, the thermal management module 100 may not be provided with the detection sensor 55, and the effect of predicting a crisis and activating the fire extinguishing device 50 in time can be achieved by using an external signal.

[0064] In the vehicle application scenario, the detection source of the thermal management module 100 can come from the original detection system of the vehicle, or from the detection sensor 55 of the thermal management module 100 itself. For example, the vehicle is originally equipped with an acceleration sensor 2300, a collision sensor 2400, etc. The control switch 53 is a solenoid valve, and the opening and closing of the solenoid valve is controlled by the vehicle control system. There may be two situations: when the vehicle collides, the control system detects the collision through the acceleration sensor 2300, automatically issues a command to open the solenoid valve, and cuts off the power supply at the same time to prevent electric sparks from causing secondary fires; when the vehicle collision sensor 2400 does not give the control system collision information, but the upper temperature sensor of the refrigerant side component 20 detects a temperature that may cause fire, and the temperature value exceeds the threshold set by the system, the solenoid valve is automatically opened to release the fire extinguishing agent for fire extinguishing.

[0065] In some embodiments, Figure 1 As shown, the thermal management module 100 further includes: a protective cover 10 , a refrigerant side component 20 disposed in the protective cover 10 , and at least a nozzle 511 on the fire protection device 50 disposed in the protective cover 10 .

[0066] The protective cover 10 can provide protection for the refrigerant side component 20. When the thermal management module 100 is impacted, the protective cover 10 can absorb the impact force, so that the protective cover 10 can provide anti-collision protection for the refrigerant side component 20, reducing or avoiding refrigerant leakage caused by the impact of the refrigerant side component 20.

[0067] In some schemes, the detection sensor 55 is a refrigerant concentration sensor, which can timely feedback the refrigerant concentration in the accommodating cavity 110 of the protective cover 10, so that it can timely detect whether the refrigerant concentration in the accommodating cavity 110 is too high, and whether there is a refrigerant leakage problem in the refrigerant side component 20, so as to facilitate timely handling of the situation of excessive refrigerant concentration or refrigerant leakage, thereby improving the safety of the thermal management module 100.

[0068] It is understandable that when the refrigerant concentration sensor detects a refrigerant leak, there is no limitation on how to deal with this problem. For example, a prompt may be given to the user, and the user may check or manually open the protective cover 10 to allow the leaked refrigerant to be discharged from the protective cover 10. Another example is to provide an exhaust device (not shown) to exhaust the gas in the protective cover 10.

[0069] In addition, when the refrigerant concentration sensor detects a refrigerant leakage and the leakage accumulates to a certain amount, there will be a shortage of refrigerant in the thermal management module 100. The user can replenish the refrigerant in time according to this information, thereby ensuring the performance of the thermal management module 100 by replenishing the refrigerant. For example, the cooling or heating energy efficiency of the thermal management module 100 will not decrease.

[0070] In addition, when a refrigerant leakage problem is detected and there are certain danger sources in the external environment, the control switch 53 can be controlled in time to open the nozzle 511 so that the fire extinguishing agent can be sprayed out in time to prevent leakage or block the danger source.

[0071] Specifically, the protective cover 10 is a closed cavity. It is understandable that the refrigerant side component 20 and the fire protection device 50 are preferably located in a relatively closed or partially closed space, and the volume of the space can be as small as possible, so that on the one hand, the scope of the fire can be reduced, and at the same time, the fire extinguishing agent can be effectively guided during the release process of the fire extinguishing agent to extinguish the fire more effectively, so as not to cause a waste of part of the fire extinguishing agent.

[0072] Of course, the utility model solution may not be limited thereto, for example, a vent is provided on the protective cover 10. At this time, the vent and the fire protection device 50 are arranged with certain care, that is, the nozzle 511 should not face the vent, so as to reduce the waste of fire extinguishing agent as much as possible.

[0073] In addition, the initial amount of fire extinguishing medium is calculated based on the amount of refrigerant on fire, and has a sufficient safety factor to ensure complete fire extinguishing in various extreme situations and prevent the fire from spreading to other locations.

[0074] Specifically, the fire prevention device 50 is installed in the protective cover 10 and can be protected by the protective cover 10. The specific position of the fire prevention device 50 in the protective cover 10 is not limited, for example, it can be set above the refrigerant side component 20, or on the side of the refrigerant side component 20. The protective cover 10 can be installed on the refrigerant side component 20, or on the protective cover 10 or the water side component 30.

[0075] In some embodiments, the nozzle 511 is spaced apart from the refrigerant side component 20 to provide the nozzle 511 with a certain spraying space to prevent the nozzle 511 from being blocked and causing failure.

[0076] Specifically, Figure 1 As shown, the water side component 30 is arranged in the protective cover 10 and is located above the refrigerant side component 20, and the fire protection device 50 is installed at the bottom of the water side component 30, so that the fire retardant sprayed by the fire protection device 50 can sink under the action of gravity and better cover the refrigerant side component 20, thereby reducing the time required for covering and the amount of fire extinguishing agent used.

[0077] Among them, the water side component 30 is located above the refrigerant side component 20. It can be understood that such a structure can realize the water side component 30 and the refrigerant side component 20 being arranged up and down, and can realize the integration of the water side component 30 and the refrigerant side component 20; on the other hand, because the refrigerant side component 20 is provided with a compressor, the weight of the compressor is heavy, and after the water side component 30 is placed above the refrigerant side component 20, the overall center of gravity of the thermal management module 100 can be close to the bottom, ensuring the structural stability of the thermal management module 100, thereby ensuring the working performance of the thermal management module 100; in addition, it is also convenient to add coolant to the water tank of the water side component 30, reducing the difficulty of adding coolant.

[0078] In addition, after the water side component 30 and the refrigerant side component 20 are integrated, when the water side component 30 and the refrigerant side component 20 are connected in cooperation, the extension length of the connection component can be reduced, which is conducive to reducing the weight of the thermal management module 100 and reducing the cost of the thermal management module 100, thereby realizing a compact and low-cost setting of the thermal management module 100. When the thermal management module 100 is assembled in the vehicle 10000, it can not only realize the reasonable use of the space inside the vehicle and facilitate the layout of the entire vehicle, but also realize the reduction of the burden and improvement of the efficiency of the vehicle 10000.

[0079] Therefore, by setting the relative position of the water side component 30 and the refrigerant side component 20, and placing the water side component 30 above the refrigerant side component 20, while reducing the difficulty of adding coolant to the water side component 30, the position stability of the thermal management module 100 can also be improved, and the miniaturization, modularization and compact setting of the thermal management module 100 can be achieved, thereby reducing the space occupied by the thermal management module 100 and reducing the difficulty of installing the thermal management module 100.

[0080] Furthermore, the water side component 30 and the refrigerant side component 20 are spaced apart, that is, the water side component 30 is placed above the refrigerant side component 20 and spaced apart from the refrigerant side component 20. This can avoid resonance between the water side component 30 and the refrigerant side component 20 to a certain extent, improve the structural stability of the thermal management module 100, ensure the improvement of the working performance of the thermal management module 100, and help to extend the service life of the thermal management module 100.

[0081] Preferably, the minimum distance between the water side component 30 and the refrigerant side component 20 is set to 10mm-50mm. This can avoid resonance between the water side component 30 and the refrigerant side component 20 to a certain extent, while also reducing the space occupied by the thermal management module 100 in the up and down directions, thereby facilitating the miniaturization and compactness of the thermal management module 100.

[0082] Further, the nozzle 511 is located at the bottom of the fire protection device 50 and is arranged at intervals above the refrigerant side component 20. In this way, the fire extinguishing agent is sprayed onto the water side component 30 as little as possible, the nozzle 511 will not be blocked, and the waste of the fire extinguishing agent is reduced.

[0083] According to the thermal management system 1000 of the second embodiment of the utility model, Figure 2 As shown, it includes: the thermal management module 100 of the first aspect embodiment mentioned above, and the thermal management module 100 is not described in detail here.

[0084] The thermal management system 1000 of the present invention adopts the thermal management module 100 of the above embodiment and utilizes the fire prevention device 50 to improve the fire resistance and safety of the thermal management module 100 .

[0085] According to the vehicle 10000 of the embodiment of the utility model, Figure 2 As shown, a thermal management system 1000 including the above-mentioned embodiment is provided.

[0086] The vehicle 10000 of the present invention adopts the thermal management system 1000 of the above embodiment and utilizes the fire prevention device 50 to improve the fire resistance and safety of the thermal management module 100, thereby improving the fire safety of the entire vehicle.

[0087] Specifically, Figure 3 As shown, the vehicle 10000 has an on-board control system 2000, which is electrically connected to the control switch 53 to control the opening and closing of the nozzle 511. That is to say, even if the thermal management system 1000 does not have its own detection sensor 55, the vehicle 10000 can control the timely operation of the fire prevention device 50 through its own original detection function, which can reduce the number of sensors set and reduce costs. In addition, the on-board control system 2000 has most of the information data of the vehicle 10000, the detection data obtained is more comprehensive, the detection reliability is higher, the control of the fire prevention device 50 is more accurate, and the waste of fire extinguishing agent and the trouble of cleaning after improper use are avoided.
