DETAILED DESCRIPTION

[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] In order to solve the technical problem that the existing vehicle cooling module cannot meet the heat dissipation requirements under different working conditions, firstly, Figure 2 As shown, the present application provides a vehicle cooling module 100 , which mainly includes a condenser 10 , a radiator 20 , a first sensor 30 and a controller 40 .

[0059] Among them, the condenser 10 is used to be connected to the compressor (not shown) on the vehicle 200. Specifically, the condenser 10 and the compressor are important components of the air-conditioning system of the vehicle 200. The compressor is used to compress the refrigerant (or refrigerant) into a high temperature and high pressure state. The condenser 10 serves as a high-pressure heat dissipation component in the air-conditioning system. When the refrigerant flows through the condenser 10, the refrigerant releases heat and transfers the heat to the condenser 10. When the air flow flows through the condenser 10, the air flow can take away the heat on the condenser 10, thereby realizing the heat dissipation of the air-conditioning system.

[0060] Of course, the refrigerant circulation loop formed by the connection between the condenser 10 and the compressor can be used for cooling the battery system in addition to air conditioning. For example, a branch passing through the battery pack can be set up so that the refrigerant flows through the battery pack and takes away the heat generated by the battery pack, thereby preventing the battery pack from overheating.

[0061] You can refer to Figure 6The vehicle 200 is generally provided with a heat dissipation channel 210, and the heat dissipation channel 210 forms a vehicle air inlet 211 at the front end of the vehicle 200. The condenser 10 is arranged in the heat dissipation channel 210. A heat dissipation fan 70 is also provided on the side of the condenser 10 away from the vehicle air inlet 211. When the heat dissipation fan 70 rotates, the air outside the vehicle can be sucked into the heat dissipation channel 210 and flow through the condenser 10, thereby taking away the heat on the condenser 10 to achieve heat dissipation.

[0062] Because the vehicle 200 is also equipped with heat dissipation devices such as motors and electronic controls that generate a lot of heat when working, in order to avoid the temperature of these heat dissipation devices being too high, please combine Figure 2 and Figure 6 To understand, the vehicle cooling module 100 also includes a radiator 20, which is arranged on the side of the condenser 10 close to the vehicle air inlet 211 and is used to dissipate heat from the heat-dissipating equipment on the vehicle 200. Specifically, in this embodiment, the radiator 20 mainly includes a heat pipe and heat dissipating fins arranged outside the heat pipe. The heat pipe is used to transmit coolant. After the coolant absorbs heat in heat dissipating equipment such as motors and electronic controls, it flows into the heat dissipating pipe of the radiator 20. When the airflow flows through the radiator 20, the airflow can take away the heat on the radiator 20, thereby realizing the heat dissipation of heat-dissipating equipment such as motors and electronic controls. The heat dissipating fins arranged outside the heat pipe can increase the heat dissipation area of ​​the radiator 20, thereby improving the heat dissipation efficiency.

[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the overall size of the radiator 20 is smaller than the overall size of the condenser 10, so the radiator 20 is arranged on the side of the condenser 10 close to the vehicle air inlet 211, and the projection of the radiator 20 on the condenser 10 covers a part of the condenser 10. It can be understood that because the radiator 20 is located on the side of the condenser 10 close to the vehicle air inlet 211, the excess air volume of the radiator 20 can be guaranteed, thereby ensuring the heat dissipation efficiency of the radiator 20, but this will also reduce the excess air volume of the condenser 10, thereby causing the condenser 10 to be unable to meet the heat dissipation requirements under some working conditions (such as when the heat dissipation requirements of the air conditioner or battery pack are large).

[0064] Therefore, in the present application, one of the radiator 20 and the condenser 10 can move relative to the other to form ventilation gaps 60 of different sizes between the radiator 20 and the condenser 10. For example, Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the condenser 10 is fixedly arranged, and the radiator 20 is configured to be rotatable relative to the condenser 10, and when the radiator 20 is rotated to different positions, the angle between the radiator 20 and the condenser 10 is different. The angle space between the radiator 20 and the condenser 10 is the ventilation gap 60, that is, the larger the angle between the radiator 20 and the condenser 10, the larger the ventilation gap 60, and the ventilation gaps 60 of different sizes enable the condenser 10 to have different airflows.

[0065] Specifically, if Figure 6 As shown, when the airflow flowing into the heat dissipation channel 210 from the vehicle air inlet 211 flows to the position of the radiator 20, the airflow will be divided into two parts, one part directly passes through the radiator 20 and takes away the heat on the radiator 20, and the other part bypasses the radiator 20 from above the radiator 20. The part of the airflow bypassing the radiator 20 is further divided into two parts, one part directly flows forward through the condenser 10, and the other part first flows to the ventilation gap 60 between the radiator 20 and the condenser 10, and then flows forward through the condenser 10, thereby taking away the heat on the condenser 10. It can be understood that by controlling the size of the ventilation gap 60, the airflow of the condenser 10 can be controlled, so that the condenser 10 can meet different heat dissipation requirements.

[0066] Of course, in other embodiments, the radiator 20 may be fixed and the condenser 10 may rotate relative to the radiator 20; or, both the radiator 20 and the condenser 10 may be rotatably installed, and either one may rotate relative to the other; or, either the radiator 20 or the condenser 10 may be moved closer to or away from the other by translation, so that ventilation gaps 60 of different sizes may be formed between the radiator 20 and the condenser 10.

[0067] In order to adjust the size of the ventilation gap 60 according to the heat dissipation requirements, as shown in FIG. Figure 2 As shown, the vehicle cooling module 100 of the present application also includes a first sensor 30 and a controller 40. The first sensor 30 is used to monitor the exhaust pressure or exhaust temperature of the compressor, and the controller 40 is used to control the movement of one of the condenser 10 and the radiator 20 relative to the other according to the exhaust pressure or exhaust temperature to adjust the size of the ventilation gap 60.

[0068] Specifically, the exhaust pressure or exhaust temperature of the compressor can reflect the heat dissipation effect of the condenser 10. When the exhaust pressure or exhaust temperature of the compressor is too high, it means that the heat dissipation effect of the condenser 10 is not good. At this time, it is necessary to improve the heat dissipation efficiency of the condenser 10, that is, the condenser 10 has a greater heat dissipation demand. Therefore, by monitoring the exhaust pressure and exhaust temperature of the compressor through the first sensor 30, the heat dissipation demand under the current working condition can be better clarified, and then the size of the ventilation gap 60 can be adjusted according to the heat dissipation demand.

[0069] It should be noted here that when it is necessary to monitor the exhaust pressure of the compressor, the specific type of the first sensor 30 may be a pressure sensor, and when it is necessary to monitor the exhaust temperature of the compressor, the specific type of the first sensor 30 may be a temperature sensor.

[0070] Please combine Figures 3 to 5 After determining the heat dissipation demand of the condenser 10, the controller 40 is used to control the radiator 20 to rotate relative to the condenser 10 according to the exhaust pressure or the exhaust temperature, so that a ventilation gap 60 of a preset size is formed between the radiator 20 and the condenser 10. For example, when the heat dissipation demand of the condenser 10 is large, the angle between the radiator 20 and the condenser 10 can be made larger, thereby forming a larger ventilation gap 60 and increasing the excess air volume of the condenser 10; on the contrary, when the heat dissipation demand of the condenser 10 is small, the angle between the radiator 20 and the condenser 10 can be made smaller, thereby forming a smaller ventilation gap 60 and reducing the excess air volume of the condenser 10.

[0071] It should be noted that the radiator 20 can be connected to a driving member 80 (such as a motor), and then the controller 40 is connected to the driving member 80, and then the activity of the radiator 20 is controlled by controlling the driving member 80. In addition, the controller 40 and the first sensor 30 can directly transmit signals through the connection of electrical wires, or through wireless communication technology.

[0072] In summary, it can be understood that in the vehicle cooling module 100 of the embodiment of the present application, by enabling one of the condenser 10 and the radiator 20 to move relative to the other, ventilation gaps 60 of different sizes can be formed between the radiator 20 and the condenser 10. The ventilation gaps 60 of different sizes enable the condenser 10 to have different excess air volumes. Then, the exhaust pressure or exhaust temperature of the compressor is monitored by the first sensor 30 to determine the heat dissipation requirement. Then, the controller 40 is used to control one of the condenser 10 and the radiator 20 to move relative to the other, so that the ventilation gap 60 between the radiator 20 and the condenser 10 matches the heat dissipation requirement, that is, the excess air volume of the condenser 10 matches the heat dissipation requirement, thereby being able to meet the heat dissipation requirements under different working conditions. This not only effectively solves the technical problem that the existing vehicle cooling module 100 cannot meet the heat dissipation requirements under different working conditions, but also has low energy consumption and is easy to control.

[0073] Optionally, in one embodiment, please combine Figures 2 to 5, the radiator 20 is configured to be able to rotate and switch between the first position L1, the second position L2 and the third position L3, and when the radiator 20 is in the first position L1, the second position L2 and the third position L3 respectively, the angle between the radiator 20 and the condenser 10 increases successively, and the air flow of the condenser 10 also increases successively. Therefore, when the heat dissipation demand of the condenser 10 is small, the radiator 20 can be controlled to rotate to the first position L1, when the heat dissipation demand of the condenser 10 is medium, the radiator 20 can be controlled to rotate to the second position L2, and when the heat dissipation demand of the condenser 10 is large, the radiator 20 can be controlled to rotate to the third position L3.

[0074] It can be understood that by presetting the first position L1, the second position L2 and the third position L3, this embodiment can directly control the radiator 20 to rotate to the corresponding position under different working conditions. This can simplify the control program in the controller 40, thereby making the controller 40's control of the radiator 20 simpler and more convenient.

[0075] It should be noted here that in order to facilitate the control of the radiator 20 to rotate and switch between the first position L1, the second position L2 and the third position L3 according to the exhaust pressure or exhaust temperature of the compressor, a reference pressure or a reference temperature can be set, and then the rotation of the radiator 20 can be controlled according to the relationship between the exhaust pressure and the reference pressure, or the rotation of the radiator 20 can be controlled according to the relationship between the exhaust temperature and the reference temperature.

[0076] For example, optionally, in one embodiment, the controller 40 is used to control the radiator 20 to rotate relative to the condenser 10 according to the exhaust pressure. Figure 2 As shown, when the exhaust pressure is less than or equal to the first reference pressure, the controller 40 controls the radiator 20 to switch to one of the first position L1, the second position L2 and the third position L3. Specifically, because the exhaust pressure is less than the first reference pressure, it means that the heat dissipation demand of the condenser 10 is small. At this time, no matter which of the first position L1, the second position L2 and the third position L3 the radiator 20 is in, the air flow of the condenser 10 can meet the heat dissipation demand. At this time, the controller 40 can further determine the target position of the radiator 20 according to other conditions (such as the heat dissipation demand of the radiator 20, the wind resistance of the vehicle 200, etc.) to make the vehicle 200 have a better working state.

[0077] like Figure 4As shown, when the exhaust pressure is greater than the first reference pressure and less than the second reference pressure, the controller 40 controls the radiator 20 to switch to the second position L2. Specifically, when the exhaust pressure is greater than the first reference pressure and less than the second reference pressure, it means that the heat dissipation demand of the condenser 10 is relatively medium. At this time, the radiator 20 can be controlled to rotate to the second position L2, so that the condenser 10 has a relatively medium excess air volume, thereby adapting to the heat dissipation demand under the current working conditions.

[0078] like Figure 5 As shown, when the exhaust pressure is greater than or equal to the second reference pressure, the controller 40 controls the radiator 20 to switch to the third position L3. Specifically, when the exhaust pressure is greater than the second reference pressure, it means that the heat dissipation demand of the condenser 10 is large. At this time, the radiator 20 can be controlled to rotate to the second position L2, so that the condenser 10 has a relatively medium excess air volume, thereby adapting to the heat dissipation demand under the current working conditions.

[0079] It should be noted here that because different vehicles 200 require the condenser 10 to dissipate different amounts of heat, the first reference pressure and the second reference pressure can be flexibly set according to actual conditions, as long as the condenser 10 can have a good heat dissipation effect under different working conditions.

[0080] For another example, optionally, in one embodiment, the controller 40 is used to control the radiator 20 to rotate relative to the condenser 10 according to the exhaust temperature. When the exhaust temperature is less than or equal to the first reference temperature, the controller 40 controls the radiator 20 to switch to one of the first position L1, the second position L2 and the third position L3. Specifically, because the exhaust temperature is less than the first reference temperature, it means that the heat dissipation demand of the condenser 10 is small. At this time, no matter which of the first position L1, the second position L2 and the third position L3 the radiator 20 is in, the excess air volume of the condenser 10 can meet the heat dissipation demand. At this time, the controller 40 can further determine the target position of the radiator 20 according to other conditions (such as the heat dissipation demand of the radiator 20, the wind resistance of the vehicle 200, etc.) to make the vehicle 200 have a better working state.

[0081] Specifically, Figure 4 As shown, when the exhaust temperature is greater than the first reference temperature and less than the second reference temperature, the controller 40 controls the radiator 20 to switch to the second position L2. Specifically, when the exhaust temperature is greater than the first reference temperature and less than the second reference temperature, it means that the heat dissipation demand of the condenser 10 is relatively medium. At this time, the radiator 20 can be controlled to rotate to the second position L2, so that the condenser 10 has a relatively medium excess air volume, thereby adapting to the heat dissipation demand under the current working conditions.

[0082] like Figure 5As shown, when the exhaust temperature is greater than or equal to the second reference temperature, the controller 40 controls the radiator 20 to switch to the third position L3. Specifically, when the exhaust temperature is greater than the second reference temperature, it means that the heat dissipation demand of the condenser 10 is large. At this time, the radiator 20 can be controlled to rotate to the second position L2, so that the condenser 10 has a relatively medium excess air volume, thereby adapting to the heat dissipation demand under the current working conditions.

[0083] It should be noted here that because different vehicles 200 require different amounts of heat to be dissipated by the condenser 10, the first reference temperature and the second reference temperature can be flexibly set according to actual conditions, as long as the condenser 10 can have a good heat dissipation effect under different working conditions.

[0084] As described above, when the exhaust pressure is less than or equal to the first reference pressure, or the exhaust temperature is less than or equal to the first reference temperature, because the excess air volume of the condenser 10 can meet the heat dissipation demand of the condenser 10 under the current operating conditions regardless of whether the radiator 20 is in the first position L1, the second position L2, and the third position L3, the controller 40 can further determine the target position of the radiator 20 based on other information.

[0085] For example, optionally, in one embodiment, Figure 2 As shown, the radiator 20 dissipates heat from the heat release device through the coolant, and the vehicle cooling module 100 further includes a second sensor 50, which is used to monitor the outlet water temperature of the coolant when it flows out of the heat release device. When the exhaust pressure is less than the first reference pressure or the exhaust temperature is less than the first reference temperature, the controller 40 also controls the radiator 20 to switch to one of the first position L1, the second position L2 and the third position L3 according to the outlet water temperature.

[0086] For details, please combine Figure 2 and Figure 6 To understand, in order to reduce the wind resistance of the whole vehicle, the air outlet of the vehicle 200 is generally set to be smaller. At this time, in order to ensure the excess air volume of the condenser 10, the condenser 10 is tilted in the heat dissipation channel 210. When the radiator 20 is in the first position L1, the second position L2 and the third position L3, respectively, the excess air volume of the radiator 20 decreases successively, that is, when the radiator 20 is in the first position L1, the excess air volume is large and the heat dissipation efficiency is high, when it is in the second position L2, the excess air volume is medium and the heat dissipation efficiency is medium, and when it is in the third position L3, the excess air volume is small and the heat dissipation efficiency is low.

[0087] Because the radiator 20 dissipates heat to heat-releasing devices such as motors and electronic controls through coolant, this embodiment monitors the outlet water temperature of the coolant when it flows out of the heat-releasing devices, and the controller 40 further determines the target position of the radiator 20 based on the outlet water temperature to improve the heat dissipation efficiency of the entire vehicle cooling module 100.

[0088] Specifically, when the outlet water temperature of the coolant flowing out of the heat release device is high, it means that the heat dissipation effect of the radiator 20 is not good, and the heat dissipation efficiency of the radiator 20 needs to be improved. At this time, the radiator 20 can be controlled to rotate and switch to the first position L1 to increase the excess air volume of the radiator 20, thereby improving the heat dissipation efficiency of the radiator 20. When the outlet water temperature of the coolant flowing out of the heat release device is medium, the radiator 20 can be controlled to rotate and switch to the second position L2, so that the excess air volume of the radiator 20 matches the heat dissipation requirements of the current working conditions. When the coolant flows out of the heat release device so that the outlet water temperature is low, the radiator 20 can be controlled to rotate and switch to the third position L3 to reduce the excess air volume of the radiator 20, so as to avoid the temperature of the coolant being too low after the heat is dissipated at the radiator 20, thereby affecting the heat recovery function at other positions on the vehicle 200.

[0089] It should be noted here that in order to facilitate the controller 40 to determine the target position of the radiator 20 according to the outlet water temperature when the coolant flows out of the heat release device, a reference water temperature can be set, and then the heat dissipation requirements of the radiator 20 can be determined based on the relationship between the outlet water temperature and the reference water temperature.

[0090] For example, optionally, in one embodiment, a first reference water temperature and a second reference water temperature are set, such as Figure 5 As shown, when the outlet water temperature is less than or equal to the first reference water temperature, it indicates that the heat dissipation demand of the radiator 20 is relatively low. At this time, the controller 40 can control the radiator 20 to switch to the third position L3 to reduce the excess air volume of the radiator 20 .

[0091] like Figure 4 As shown, when the outlet water temperature is greater than the first reference water temperature and less than the second reference water temperature, it indicates that the heat dissipation demand of the radiator 20 is medium. At this time, the controller 40 can control the radiator 20 to switch to the second position L2 so that the excess air volume of the radiator 20 matches the heat dissipation demand under the current working conditions.

[0092] like Figure 2 As shown, when the outlet water temperature is greater than or equal to the second reference water temperature, it indicates that the heat dissipation demand of the radiator 20 is relatively high. At this time, the controller 40 can control the radiator 20 to switch to the first position L1 to increase the air flow of the radiator 20 .

[0093] It should be noted here that because different vehicles 200 require different amounts of heat to be dissipated by the radiator 20, the first reference water temperature and the second reference water temperature can be flexibly set according to actual conditions, as long as the condenser 10 can have a good heat dissipation effect under different working conditions.

[0094] Optionally, in one embodiment, as Figure 2As shown, when the radiator 20 is at the first position L1 , the radiator 20 is parallel to the condenser 10 , which can make the structure of the vehicle cooling module 100 more compact.

[0095] Optionally, in one embodiment, as Figure 5 and Figure 6 As shown, the condenser 10 is tilted relative to the axis 2111 of the vehicle air inlet 211, which can reduce the wind resistance of the whole vehicle and increase the air flow through the condenser 10. When the radiator 20 is in the third position L3, the radiator 20 extends perpendicular to the axis 2111 of the vehicle air inlet 211, which can ensure that there is a sufficient ventilation gap 60 between the radiator 20 and the condenser 10, and avoid the size of the gap between the radiator 20 and the upper guide wall 212, thereby ensuring the air flow bypassing the radiator 20 from above the radiator 20.

[0096] Optionally, in one embodiment, as Figure 2 As shown, the radiator 20 has a relative connecting end 21 and a sliding end 22, the connecting end 21 is used for rotational installation on the vehicle 200, specifically, the connecting end 21 can be rotatably connected to the lower guide wall 213, and can also be rotatably installed on the mounting frame 90 (the mounting frame 90 is a component for mounting the condenser 10, the cooling fan 70 and the radiator 20), the sliding end 22 can rotate around the connecting end 21, and the vehicle cooling module 100 also includes a slide rail 91, the slide rail 91 extends in a curve with the connecting end 21 as the center, and the sliding end 22 is slidably installed on the slide rail 91. It can be understood that by providing the slide rail 91 to support the sliding end 22 of the radiator 20, the rotation of the radiator 20 can be made more stable.

[0097] like Figure 6 As shown, according to the second aspect of the present application, a vehicle 200 is provided, and the vehicle 200 includes a vehicle cooling module 100 according to any one of the above embodiments, so the vehicle 200 has all the beneficial effects of the above vehicle cooling module 100, which will not be repeated in this disclosure.

[0098] It should be noted that the vehicle 200 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and the present disclosure does not make any specific limitation on this.

[0099] Optionally, in one embodiment, as Figure 6As shown, the vehicle 200 is provided with a heat dissipation channel 210, which can be formed by enclosing an air guide cover, or by enclosing an air guide cover and part of the inner wall of the vehicle 200. The heat dissipation channel 210 forms a vehicle air inlet 211 on the surface of the vehicle 200, and the heat dissipation channel 210 has an upper guide wall 212 and a lower guide wall 213 that are spaced and opposite to each other. The condenser 10 extends from the lower guide wall 213 to the upper guide wall 212, and the radiator 20 extends from the lower guide wall 213 to the upper guide wall 212, and the radiator 20 is spaced from the upper guide wall 212. While the upper guide wall 212 extends away from the vehicle air inlet 211, it also at least partially extends in a direction away from the lower guide wall 213, so that a part of the airflow can bypass the radiator 20 under the guidance of the upper guide wall 212 and flow directly to the condenser 10, thereby improving the heat dissipation efficiency.

[0100] Thirdly, Figure 7 and Figure 8 As shown, the present application also provides a control method of a vehicle cooling module 100, the vehicle cooling module 100 includes a condenser 10 and a radiator 20 that can move relatively, and the control method includes:

[0101] Step S1: Obtaining the exhaust pressure P or exhaust temperature K of the compressor;

[0102] Step S2 : controlling the radiator 20 to move to a target position according to the exhaust pressure P or the exhaust temperature K, so as to increase or decrease the ventilation gap 60 between the radiator 20 and the condenser 10 .

[0103] In step S1, the exhaust pressure P or exhaust temperature K of the compressor can be monitored and obtained by the first sensor 30. When the exhaust pressure P needs to be obtained, the first sensor 30 can be a pressure sensor, and when the exhaust temperature K needs to be obtained, the first sensor 30 can be a temperature sensor.

[0104] Optionally, in one embodiment, the radiator 20 is rotatable relative to the condenser 10, and step S2 includes:

[0105] Step S21: comparing the exhaust pressure P, the first reference pressure P1 and the second reference pressure P2, or comparing the exhaust temperature K, the first reference temperature K1 and the second reference temperature K2;

[0106] Step S221: when the exhaust pressure P is less than or equal to the first reference pressure P1, or the exhaust temperature K is less than the first reference temperature K1, the radiator 20 is controlled to switch to one of the first position L1, the second position L2 and the third position L3;

[0107] Step S222: when the exhaust pressure P is greater than the first reference pressure P1 and less than the second reference pressure P2, or the exhaust temperature K is greater than the first reference temperature K1 and less than the second reference temperature K2, the radiator 20 is controlled to switch to the second position L2;

[0108] Step S223: when the exhaust pressure P is greater than or equal to the second reference pressure P2, or the exhaust temperature K is greater than the second reference temperature K2, the radiator 20 is controlled to switch to the third position L3;

[0109] When the radiator 20 is at the first position L1, the second position L2 and the third position L3 respectively, the angle between the radiator 20 and the condenser 10 increases successively.

[0110] Optionally, in one embodiment, the radiator 20 dissipates heat from the heat-dissipating device on the vehicle 200 through a coolant, and step S221 includes:

[0111] Step S3: obtaining the outlet water temperature T of the coolant when it flows out of the heat release device;

[0112] Step S4: comparing the outlet water temperature T, the first reference water temperature T1 and the second reference water temperature T2;

[0113] Step S51: when the outlet water temperature T is less than or equal to the first reference water temperature T1, the radiator 20 is controlled to switch to the third position L3;

[0114] Step S52: when the outlet water temperature T is greater than the first reference water temperature T1 and less than the second reference water temperature T2, the radiator 20 is controlled to switch to the second position L2;

[0115] Step S53: when the outlet water temperature T is greater than or equal to the second reference water temperature T2, the radiator 20 is controlled to switch to the first position L1.
