[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] Figure 1 It is a schematic structural diagram of a vehicle provided in some embodiments of the present application.

[0033] like Figure 1 As shown, the first aspect of an embodiment of the present application provides a vehicle auxiliary cooling system, including a pipe assembly 10 and a conveying assembly (not shown in the figure), the pipe assembly 10 includes a pipe 11 and a plurality of nozzles 12 arranged on the pipe 11, the pipe 11 is used to be arranged on the top of the vehicle body 200, and the plurality of nozzles 12 are arranged at intervals along the length direction of the pipe 11; the conveying assembly is connected to the pipe 11, and the conveying assembly is used to convey coolant to the pipe 11.

[0034] It should be noted that the auxiliary cooling system for vehicles according to the embodiments of the present application is particularly suitable for use as an auxiliary cooling system for passenger vehicles, but is not limited to such use. If the auxiliary cooling system provided by the present application is used on other types of vehicles, it should also fall within the scope of protection of the present application. For example, the auxiliary cooling system for vehicles according to the embodiments of the present application can also be used on electric vehicles, ships, spacecraft, and the like.

[0035] The coolant can be water or other volatile liquids. A delivery assembly can be provided inside the vehicle body 200 and can be used to store the coolant and deliver the coolant to the pipe 11. The coolant is then sprayed onto the top of the vehicle body 200 through the nozzle 12. The top of the vehicle body 200 refers to the front bonnet 210, the roof 220, etc. The pipe 11 can be fixed to the top of the vehicle body 200 by means of snaps, bolts, or bonding. The pipe 11 can be directly exposed to the top of the vehicle body 200 or shielded by a cover. The nozzles 12 can be evenly spaced along the length of the pipe 11 or unevenly spaced.

[0036] The vehicle auxiliary cooling system can be used alone or in conjunction with the vehicle's air conditioning system. For example, the air conditioning system can be turned on while the nozzle 12 sprays coolant onto the top of the vehicle body 200. Alternatively, the vehicle auxiliary cooling system can be turned on first, and then the air conditioning system can be turned on if the temperature inside the vehicle is still high.

[0037] In the embodiment of the present application, the coolant is delivered to the pipe 11 through the delivery assembly, and the coolant is then ejected from the nozzle 12, so that the main heating surface of the vehicle (the top of the vehicle body 200) remains moist. The evaporation of the coolant absorbs heat, which effectively reduces the temperature of the top heating surface of the vehicle body 200 and effectively reduces the temperature rise of the vehicle body 200 caused by the transfer of ambient heat, thereby effectively reducing the cooling load of the vehicle air conditioning compressor system, thereby effectively reducing the energy consumption of the air conditioning system, improving fuel economy, and increasing the cruising range. At the same time, it can reduce the performance requirements of the vehicle air conditioning compressor system to a certain extent, saving costs.

[0038] In order to facilitate the cooling effect of the vehicle auxiliary cooling system of the embodiment of the present application, taking an ordinary small car as an example, if the area of ​​the front hood 210 and the roof 220 of the vehicle is about 6 square meters, according to the total solar radiation in Shanghai from June to August and the average number of sunshine hours in the corresponding months, the average solar radiation in Shanghai in the above months can be obtained as a = 2.61MJ / HM 2 =2.61×10 3 KJ / HM 2 The total amount of solar radiation energy on the heated surface of the vehicle per hour is N = F × a = 6 × 2.61 × 10 3 =15.66×10 3 KJ. The specific heat capacity of steel is c = 450 J / (kg·K). Assuming that the top of the vehicle body 200 weighs 100 kg, under the above conditions, if the radiation heat dissipation of the vehicle body 200 is not considered and assuming that 20% of the solar radiation energy is absorbed by the vehicle body 200, then one hour of sunlight can cause the top of the vehicle body 200 to heat up by T = N / (c×m) = 15.66×10 3× 20% / (0.45 × 100) = 70 ° C. The heat of vaporization of water is 2330 kJ / kg. Therefore, the complete evaporation of 1 kg of water absorbs 2330 kJ, which can reduce the temperature of the heated surface by t = 2330 ÷ (0.45 × 100) = 52 ° C. It can be seen that the cooling effect is significant.

[0039] In some embodiments, the delivery component includes a liquid storage tank and a pressure pump connected to each other, the pressure pump is connected to the pipeline 11, the liquid storage tank is used to store the coolant, and the pressure pump is used to deliver the coolant to the pipeline 11.

[0040] The liquid reservoir and the booster pump can be located within the engine compartment of the vehicle body 200. The booster pump can be a water pump that pressurizes the coolant in the reservoir and delivers it to the pipe 11 located on top of the vehicle body 200. The water level in the reservoir can also be detected using a float-type water level gauge, a pressure sensor, an ultrasonic sensor, a conductive liquid level sensor, or the like. If the water level in the reservoir is detected to be below a lower limit, an alarm can be activated to remind the user to add coolant. The aforementioned water level gauge or sensor can also be electrically or communicatively connected to the vehicle's body control module (BCM). During use, coolant is first added to the reservoir. If the water level in the reservoir is detected to be above the lower limit, the BCM is in a ready state.

[0041] It should be noted that the body control module (BCM) is a vehicle electronic control unit responsible for managing and controlling the electrical and electronic systems associated with the vehicle body 200. The BCM's primary function is to coordinate and monitor various electronic and electrical devices within the vehicle to ensure proper operation, comfort, and safety. For example, the BCM manages the vehicle's lighting system, power windows, and power door locks, as well as controlling the speed and interval of the windshield wipers, as well as their start and stop functions and the spraying of the washers. The BCM also coordinates the vehicle's climate control system, including the air conditioning, heating, and ventilation systems, and manages the vehicle's anti-theft and alarm systems, including security alarms, remote start, and remote locking.

[0042] The embodiment of the present application can realize the automatic transportation of coolant from a low place to a high place through the provision of a liquid storage tank and a pressure pump, thereby improving the transportation efficiency.

[0043] In some embodiments, the vehicle auxiliary cooling system further includes a first temperature sensor 30 disposed on the top of the vehicle body 200 , and the first temperature sensor 30 is configured to be electrically connected to a vehicle body control module.

[0044] There can be multiple first temperature sensors 30, each of which can be installed on the front hood 210, the roof 220, or the like. For example, four first temperature sensors 30 can be installed on the front hood 210, with two located on the left side of the front hood 210 and the other two located on the right side. Alternatively, one first temperature sensor 30 can be installed on each of the left and right sides of the skylight 230 on the roof 220. The body control module receives the temperatures measured by each of the first temperature sensors 30 and, if there are any differences in the temperatures measured by the first temperature sensors 30, calculates an average temperature value.

[0045] If the body control module detects that the temperature of the top of the vehicle body 200 has a rapid rising trend, for example, if the rising speed of the temperature of the top of the vehicle body 200 exceeds a first threshold, the body control module controls the liquid storage tank and the booster pump to start, and the nozzle 12 sprays coolant to the top of the vehicle body 200 to reduce the vehicle temperature.

[0046] A second aspect of the present application provides a vehicle, comprising a vehicle body 200, an air conditioning system, and a vehicle auxiliary cooling system according to any of the aforementioned embodiments; the air conditioning system is located within the vehicle body 200. Because the vehicle utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be detailed here.

[0047] In some embodiments, the duct 11 is arranged to extend along the transverse direction X of the vehicle body 200 .

[0048] The vehicle body 200 has a transverse direction X and a longitudinal direction Y. The pipe 11 is extended along the transverse direction X. The plurality of nozzles 12 are also arranged at intervals along the transverse direction X. The nozzles 12 can spray to multiple locations on the top of the vehicle body 200, thereby increasing the spraying area of ​​the coolant.

[0049] Optionally, the nozzle 12 is directed toward the rear end of the vehicle body 200 , so that the coolant can be sprayed backward onto the surface of the top of the vehicle body 200 in accordance with the airflow when the vehicle is moving.

[0050] In some embodiments, there are multiple duct assemblies 10 , and the vehicle body 200 includes at least a front bonnet 210 and a top cover 220 . The top of the front bonnet 210 and the top of the top cover 220 are both provided with duct assemblies 10 .

[0051] The hood 210, also known as the hood or engine cover, is one of the front components of a vehicle. It is located at the front of the vehicle and covers and protects the vehicle's engine and related mechanical components. The hood 210 primarily protects the vehicle's engine from the external environment and collisions. The roof 220 is the upper outer shell of the vehicle, covering the passenger compartment and providing shade, protecting occupants from weather and other external elements.

[0052] In the embodiment of the present application, pipes 11 are provided on the top of the front bonnet 210 and the top cover 220, which can cool the front bonnet 210 and the top cover 220 that are exposed to more sunlight and have the largest heating area, so that the internal temperature of the vehicle can also be reduced, thereby improving the cooling efficiency.

[0053] In some embodiments, one of the duct assemblies 10 is disposed at a leading edge of the front bonnet 210 .

[0054] The first temperature sensor 30 may be provided at the rear side of the duct assembly 10 to detect a temperature change of the front bonnet 210 .

[0055] In the embodiment of the present application, the pipe assembly 10 is arranged at the front edge of the front bonnet 210 to follow the airflow when the vehicle is started. The coolant can be sprayed backward to the surface of the front bonnet 210, thereby increasing the spraying area of ​​the coolant.

[0056] In some embodiments, the leading edge of the front engine cover 210 , the leading edge of the top cover 220 , and the middle area of ​​the top cover 220 are respectively provided with the duct assembly 10 .

[0057] Illustratively, two duct assemblies 10 are provided on the top of the top cover 220, one of which is located at the front edge of the top cover 220, and the other is located in the middle region of the top cover 220. Specifically, the top cover 220 is provided with a skylight 230, which is located in the front half of the top cover 220. One of the duct assemblies 10 is located in front of the skylight 230, i.e., at the front edge of the top cover 220, and can spray coolant to the front half of the top cover 220, including the skylight 230. The other duct assembly 10 is located in the back of the skylight 230, i.e., in the middle region of the top cover 220, and can spray coolant to the back half of the top cover 220.

[0058] The embodiment of the present application arranges two pipe assemblies 10 at the front edge of the top cover 220 and the middle area of ​​the top cover 220 respectively, so that the coolant can follow the airflow when the vehicle is started, and the coolant can be sprayed backward to the entire surface of the top cover 220, thereby increasing the spraying area of ​​the coolant.

[0059] Figure 2 It is a flow chart of the vehicle auxiliary cooling method provided in some embodiments of the present application.

[0060] like Figure 2 As shown, a third aspect of the embodiment of the present application further provides a vehicle auxiliary cooling method, which uses the vehicle auxiliary cooling system of any of the above embodiments, or is applied to a vehicle of any of the above embodiments, and the vehicle auxiliary cooling method includes the following steps:

[0061] S10, receiving a signal for starting the integrated cooling function.

[0062] First, the body control module and various sensors can be initialized, and then the liquid level of the liquid storage tank of the delivery component can be monitored. The water level of the liquid storage tank can be detected by a float-type water level gauge, a pressure sensor, an ultrasonic sensor, a conductive liquid level sensor, etc. If the liquid level in the liquid storage tank is detected to be lower than the lower limit value, an alarm can be sounded through the alarm device to remind the user to add coolant.

[0063] If the liquid level in the reservoir exceeds the lower limit, the system monitors the status of the integrated cooling function button. If the user presses the integrated cooling function button, the body control module receives a signal to activate the integrated cooling function. The integrated cooling function can also be activated through voice control, Bluetooth, or other modes. The integrated cooling function coordinates with the vehicle's auxiliary cooling system and the air conditioning system.

[0064] S20: Monitor the vehicle temperature and determine whether the vehicle auxiliary cooling conditions are met.

[0065] Multiple first temperature sensors 30 can be installed in locations with the largest heat-exposed surfaces, such as the front hood 210 and the roof 220. For example, four first temperature sensors 30 can be installed on the front hood 210, with two located on the left side and two located on the right side. Alternatively, one first temperature sensor 30 can be installed on each side of the sunroof 230 on the roof 220. The body control module receives the temperatures measured by each first temperature sensor 30. If there are differences in the temperatures measured by the first temperature sensors 30, the body control module calculates an average temperature. Based on this calculated average temperature, the body control module determines whether to activate auxiliary vehicle cooling. For example, if the average temperature or the rate of temperature increase exceeds a preset value, the body control module can activate the booster pump of the conveying assembly.

[0066] S30: If yes, control the delivery component to deliver the coolant to the pipeline 11.

[0067] Exemplarily, the delivery assembly includes a fluid reservoir and a pressure pump. The body control module activates the pressure pump, which draws coolant from the reservoir and pressurizes it to pipe 11 located on top of vehicle body 200. Nozzle 12 sprays the coolant onto the surface of the top of vehicle body 200. The amount of coolant sprayed per shot can be calibrated based on the vehicle model and is not specifically limited here.

[0068] S40: If not, continue to monitor the vehicle temperature.

[0069] The body control module can obtain the temperature measured by the first temperature sensor 30. If there are multiple first temperature sensors 30, the body control module can calculate the temperature average. If the temperature average or the temperature rising rate is lower than the preset value, it returns to step S20.

[0070] The embodiment of the present application uses a vehicle auxiliary cooling method to keep the vehicle's primary heating surface (the top of the vehicle body 200) moist. The evaporation of the coolant absorbs heat, effectively reducing the temperature of the top heating surface of the vehicle body 200 and the temperature rise of the vehicle body 200 caused by ambient heat transfer. This effectively reduces the cooling load of the vehicle's air conditioning compressor system, thereby effectively reducing the energy consumption of the air conditioning system, improving fuel economy, and increasing driving range. At the same time, it can reduce the performance requirements of the vehicle's air conditioning compressor system to a certain extent, saving costs.

[0071] Figure 3 This is another flow chart of the vehicle auxiliary cooling method provided in some embodiments of the present application.

[0072] like Figure 3 As shown, in some embodiments, step S20 of monitoring the vehicle temperature and determining whether the vehicle auxiliary cooling conditions are met includes:

[0073] S21 : Receive a signal of the external temperature of the top of the vehicle body 200 detected by the first temperature sensor 30 .

[0074] S22: Determine whether the rising speed of the external temperature exceeds a first threshold.

[0075] If the temperature value detected by the first temperature sensor 30 at time t1 is T1, and the temperature value detected by the first temperature sensor 30 at time t2 is T2, the temperature rise rate S is (T2-T1) / (t2-t1). If the temperature rise rate S is greater than the first threshold, the body control module controls the delivery component to deliver coolant to the pipeline 11.

[0076] The embodiment of the present application determines whether the temperature rise rate exceeds a first threshold value to obtain whether the temperature rises rapidly, thereby being able to more accurately determine whether the conditions for auxiliary cooling of the vehicle are met.

[0077] Figure 4This is another flow chart of the vehicle auxiliary cooling method provided in some embodiments of the present application.

[0078] like Figure 4 As shown, in some embodiments, if yes, then after step S40 of controlling the delivery component to deliver the coolant to the pipeline 11, the following steps are further included:

[0079] S50 : Receive a signal of the internal temperature of the vehicle body 200 detected by the second temperature sensor.

[0080] A second temperature sensor is disposed within vehicle body 200 and is configured to detect the temperature within vehicle body 200. The second temperature sensor is electrically connected to the vehicle body control module, which can obtain the temperature within vehicle body 200 detected by the second temperature sensor. Of course, there may be multiple second temperature sensors, each of which may be located at various locations within vehicle body 200. The vehicle body control module can then calculate the average temperature detected by each of the second temperature sensors.

[0081] S60: If the internal temperature exceeds a second threshold, the air conditioning system is controlled to start.

[0082] After the vehicle auxiliary cooling function is turned on, the temperature inside the vehicle body 200 will drop. However, when the external ambient temperature is very high in summer, if the temperature inside the vehicle body 200 still exceeds the second threshold, the body control module controls the air conditioning system to start and cool down together with the vehicle auxiliary cooling system.

[0083] In the embodiment of the present application, the vehicle auxiliary cooling system is first turned on to avoid using the energy-intensive air-conditioning system first. If the temperature inside the vehicle is still high, the air-conditioning system is turned on again, which can further reduce the energy consumption of the air-conditioning system, improve fuel economy, increase cruising range, and save costs.

[0084] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.
