Obviously, the implementation of the embodiments of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the utility model are described in detail below, but in addition to these detailed descriptions, the utility model may also have other embodiments.

[0105] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of the "second component", and the term "second component" itself does not imply the existence of the "first component".

[0106] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in the present invention are for illustrative purposes only and are not restrictive.

[0107] The utility model discloses a cooling system and a vehicle.

[0108] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0109] like Figure 1 , Figure 2As shown, in a preferred embodiment, a cooling system can circulate a coolant. When the cooling system is working, the flowing coolant takes away the heat of the electronic device in time, thereby cooling the electronic device. The coolant can be pure water or a propylene glycol aqueous solution, which is free of harmful substances and non-corrosive, and is suitable for use as a coolant in the cooling system.

[0110] The cooling system in this embodiment includes: a liquid supply tank 15 and a first cooling tank 16;

[0111] The liquid supply tank 15 is arranged upstream of the electronic device to be cooled along the flow of the cooling liquid, that is, the cooling liquid flows from the liquid supply tank 15 to the electronic device to be cooled, and the liquid supply tank 15 is connected to multiple electronic devices through liquid cooling pipes, and can deliver cooling liquid to the electronic devices;

[0112] The first cooling box 16 is arranged downstream of the electronic device along the flow of the cooling liquid, that is, the cooling liquid flows from the electronic device to the first cooling box 16, and the first cooling box 16 is connected to a plurality of electronic devices through a liquid cooling pipeline, and can cool the cooling liquid;

[0113] A balancing pipe 30 is connected between the liquid supply tank 15 and the first cooling tank 16 , and the balancing pipe 30 is used to balance the internal pressure of the cooling system.

[0114] The balance pipe 30 includes more than two pipes, and the coolant flows in different directions in the balance pipe 30, and can flow from the first cooling box 16 to the liquid supply box 15, or from the liquid supply box 15 to the first cooling box 16. By setting the balance pipe 30, bidirectional liquid flow is achieved between the first cooling box 16 and the liquid supply box 15, thereby ensuring the internal pressure balance of the entire liquid cooling pipeline of the cooling system.

[0115] The first cooling box 16 is connected to the liquid supply box 15 through a balancing pipe 30 to form a two-way circulation function. The main effects are: first, increasing the coolant circulation pipe has a further cooling effect on the returning coolant; second, due to the coolant in the entire liquid cooling pipeline of the cooling system, part of the liquid is vaporized by evaporation and boiling during the circulation process, resulting in a very high local pressure in the closed pipeline. This condition will cause pipeline damage for a long time. By setting the balancing pipe 30, the internal air pressure of the entire liquid cooling pipeline in the closed state can be balanced to avoid excessive local air pressure.

[0116] The cooling system in this embodiment is used for liquid cooling of vehicle-mounted electronic devices with high heat flux density, and can cool multiple electronic devices of the vehicle, with high integration and high heat dissipation efficiency. The cooling system has an internal pressure balance function, which can ensure the internal pressure balance of the entire liquid cooling pipeline and ensure the safe and stable operation of the cooling system.

[0117] In one embodiment, if Figure 1 As shown, it also includes:

[0118] The second cooling box 1 is arranged downstream of the electronic device and upstream of the first cooling box 16 along the coolant flow, that is, the coolant flows from the electronic device to the second cooling box 1, and then flows from the second cooling box 1 to the first cooling box 16. The second cooling box 1 is used to cool the coolant and balance the internal pressure of the cooling system.

[0119] The main purpose of setting the second cooling box 1 downstream of the electronic device is that the heat accumulation caused by the front part of the whole system is relatively high, especially the whole machine heat of the chassis controller 5 is high, and the first cooling box 16 cannot meet the cooling demand of the coolant in the loop. The second cooling box 1 can assist in heat dissipation and accelerate the reduction of the temperature of the coolant. Since the internal space of the second cooling box 1 is larger than the internal space of the liquid cooling pipeline, it can also form a release space for the gas in the entire liquid cooling pipeline to balance the internal pressure of the cooling system.

[0120] The second cooling box 1 is relatively large in size and can be placed at the rear of the vehicle.

[0121] In one embodiment, the first cooling box 16 has the same structure as the second cooling box 1 , and the second cooling box 1 is connected to the first cooling box 16 via a liquid cooling pipe.

[0122] The main functions of the first cooling box 16 and the second cooling box 1 are basically the same. Using the same structure can improve the versatility of parts and reduce design and manufacturing costs. The first cooling box 16 is used as an example for detailed structural description. The structure of the second cooling box 1 can refer to the first cooling box 16.

[0123] In one embodiment, if Figure 2 , Figure 3 As shown, the first cooling box 16 includes:

[0124] First box 161;

[0125] The external heat dissipation fins 162 are disposed on the outside of the first box body 161 and are fixedly connected to the first box body 161;

[0126] The inner heat dissipation fins 163 are disposed inside the first box body 161 and fixedly connected to the first box body 161 .

[0127] The first box body 161 , the outer heat dissipation fins 162 , and the inner heat dissipation fins 163 may be made of metal materials, such as stainless steel, which is corrosion-resistant.

[0128] The shape of the first box 161 is not limited to the cubic shape in the figure, and can also be cylindrical, spherical, L-shaped, etc. The shape of the external heat dissipation fins 162 is not limited to the rectangular plate fins in the figure, and can be other shapes such as circular collinear, circular staggered, rectangular collinear, and rectangular staggered, etc. The shape of the internal heat dissipation fins 163 is not limited to the plate fin type, and can be a hemispherical boss protruding inward, a concave groove, etc.

[0129] The outer heat dissipation fins 162 are mainly used to increase the contact area between the first box 161 and the outside air, and enhance the heat exchange capacity. The inner heat dissipation fins 163 are mainly used to increase the contact area between the first box 161 and the coolant to be cooled inside, so as to increase the heat exchange area, so that the coolant inside the first cooling box 16 can be quickly cooled. The outer heat dissipation fins 162 and the inner heat dissipation fins 163 can be connected one by one, or made in one piece, or can be not connected.

[0130] The height and density of the outer heat dissipation fins 162 and the inner heat dissipation fins 163 can be designed differently, depending on the total heat power of the cooling system. If the total heat power of the cooling system is high, the height and density of the outer heat dissipation fins 162 and the inner heat dissipation fins 163 can be larger; if the total heat power of the cooling system is low, the height and density of the outer heat dissipation fins 162 and the inner heat dissipation fins 163 can be smaller.

[0131] In one embodiment, if Figure 2 As shown, the first cooling box 16 also includes:

[0132] A plurality of water inlets, the water inlets being arranged at the lower part and / or the bottom of the first cooling box 16;

[0133] A plurality of water outlets, the water outlets being arranged at the upper part and / or the top of the first cooling box 16;

[0134] At least one water inlet and one water outlet are used to connect to the balancing pipe 30, so the balancing pipe 30 includes at least two pipes.

[0135] Figure 2 The lower part of the first cooling box 16 is provided with water inlet 164 and water inlet 165, and the top of the first cooling box 16 is provided with water outlet 166 and water outlet 167. For example, the water inlet 164 can be selected to connect to the first pipe in the balancing pipe 30 (the first pipe is also connected to the liquid supply box 15), and the water outlet 167 can be selected to connect to the second pipe in the balancing pipe 30 (the second pipe is also connected to the liquid supply box 15).

[0136] like Figure 3As shown, the water inlet 164 and the water inlet 165 of the first cooling box 16 are respectively arranged on the diagonal sides of the first box body 161, and the water outlet 166 and the water outlet 167 are arranged on the top of the first cooling box 16. The main purpose is to allow the coolant to be cooled inside to be fully mixed and the heat can be dissipated faster.

[0141] The liquid cooling pipe 221 in the figure is not limited to this kind of direct current pipe, and liquid cooling can also be performed by designing a flow channel inside the outer shell bracket of the central control panel 22.

[0142] In one embodiment, the heat conducting sheet 222 is made of graphene. Graphene has excellent thermal conductivity and can be made into a thin sheet structure with a small thickness. The heat conducting sheet 222 made of graphene is easy to fit the electronic components and the liquid cooling pipe 221.

[0161] The water cooling device 26 is connected to the pressure-stabilizing water tank 168 and is used to cool the coolant.

Under the heat dissipation effect of the heat dissipation fins 264, the coolant is effectively cooled in the multiple transverse water cooling channels 261, and then converges into the second longitudinal water cooling channel 263, and finally outputs the water cooling device 26 from the water outlet 266.

[0192] According to design requirements, adjustable flow water pumps can also be set at other locations in the cooling system, such as the outlet of the shift panel 9, the inlet of the second cooling box 1, etc., to overcome the high pressure loss of cooling liquid in the pipeline and promote the circulation of coolant in the pipeline.

[0193] In summary, the coolant in the cooling system has the following circuits and liquid flow directions:

[0194] Circuit 1: liquid supply tank 15 → power steering system 18 → first cooling tank 16 → liquid supply tank 15;

[0195] Loop 2: liquid supply tank 15 → auxiliary driving controller 19 → electronic rearview mirror 12 → electronic rearview mirror 20 → first cooling tank 16 → liquid supply tank 15;

[0196] Circuit three: liquid supply tank 15 → co-pilot screen 23 → central control screen 22 → instrument screen 21 → first cooling tank 16 → liquid supply tank 15;

[0197] Circuit 4: liquid supply tank 15 → shift panel 9 → first cooling tank 16 → liquid supply tank 15;

[0198] Circuit 5: liquid supply tank 15 → shift panel 9 → chassis controller 5 → second cooling tank 1 → first cooling tank 16 → liquid supply tank 15;

[0199] Circuit six: liquid supply tank 15 → shift panel 9 → media screen 7, media screen 25 → armrest screen 3, armrest screen 4 → second cooling tank 1 → first cooling tank 16 → liquid supply tank 15.

[0200] The above liquid cooling circuit is as follows Figure 1 The advantages of layout are:

[0201] First, multi-channel pipelines are connected in parallel through diverter connectors, thus avoiding the excessive front-end liquid flow pressure caused by the series connection of all electronic devices without corresponding water pump matching.

[0202] Secondly, the parallel connection of multiple pipes can effectively avoid the excessively high liquid inlet temperature of the electronic device at the rear part caused by heat accumulation, which makes the temperature of the chip inside the electronic device too high to meet the heat dissipation requirements, or the chip runs at high temperature for a long time, greatly reducing its service life.

[0203] The third is, for example: in loop one, since the power steering system 18 (EPS) has a high thermal power and a large heat dissipation demand, a separate loop is set for it, and while controlling to meet its heat dissipation conditions, it also avoids affecting the rear part of the heat dissipation unit. In loop two, since the auxiliary driving controller 19 (ADAS) and the left and right electronic rearview mirrors are all located in the front part of the vehicle, they are relatively in the same straight line, and the heat dissipation demand of the auxiliary driving controller 19 is higher than that of the left and right electronic rearview mirrors, the auxiliary driving controller 19 needs to be placed in the front part to ensure that it has a lower inlet liquid temperature. In loop three, since the front central control screen 22, the instrument screen 21 and the co-pilot screen 23 are in the same straight line and the user needs to touch the central control and the co-pilot when using them, the temperature of the central control and the co-pilot is controlled first. In loop four, there is a large space in the lower part of the shift panel 9, and a liquid cooling pipe can be set for it, and the rear part of the electronic device to be cooled can also be shunted, and a shunt connector 8 is set. In loop 5, the purpose of setting the second cooling box 1 at the rear part of the chassis controller 5 is that the chassis controller 5 has a high heat and the heat accumulation caused by the front part of the entire system is relatively high. The first cooling box 16 cannot meet the liquid cooling requirements in the loop, so the second cooling box 1 is set to assist in heat dissipation. In loop 6, the rear media screen 7, media screen 25 and armrest screen 3, armrest screen 4 need to be directly contacted by the user. In order to control the surface temperature of the screen, the two are set in series and the loop is no longer connected in series with other units.

[0205] The inlet and / or outlet ends of various vehicle-mounted electronic devices can be equipped with solenoid valves to control opening and closing, and a flow meter can also be provided to monitor the flow rate of the coolant flowing through. The shift panel 9 can add function buttons for speed regulation of each water pump in the cooling system and opening and closing of the solenoid valves.

[0206] The flow rate of each branch can also be controlled by the central control screen 22 or the rear armrest screen 3, armrest screen 4, or the temperature sensor can be used to feed back to the central controller for intelligent control by the central controller.

[0207] The number and layout of the second cooling box 1, the first cooling box 16 and the liquid supply box 15 can be changed.

[0208] Figure 1 The liquid cooling pipe shown can be made of high temperature resistant composite material, and the connection method between the liquid cooling pipe and the water cooling component of each electronic device is not limited to the quick connector 28 or the pagoda connector 29.
