[0037] Figure 1 is a schematic block diagram of a cooling system according to an embodiment of the present utility model, such as Figure 1 As shown, and refer to Figures 2 to 4The embodiment of the utility model provides a cooling system for a vehicle, including a first refrigerant flow path 110, a second refrigerant flow path 120 and a third refrigerant flow path 130. The first refrigerant flow path 110 includes a pump group 111 and a heat exchanger 112 connected in series, and a first outlet 113 and a first inlet 114 are formed at both ends of the first refrigerant flow path 110. The second refrigerant flow path 120 includes a brake control device radiator 121, and a second inlet 122 connected to the first outlet 113 and a second outlet 123 connected to the first inlet 114 are formed at both ends of the second refrigerant flow path 120. The third refrigerant flow path 130 includes a vehicle entertainment host radiator 131, and a third inlet 132 connected to the first outlet 113 and a third outlet 133 connected to the first inlet 114 are formed at both ends of the third refrigerant flow path 130. After the liquid refrigerant flows out from the first outlet 113 , at least a portion flows into the second refrigerant flow path 120 , and at least another portion flows into the third refrigerant flow path 130 . After flowing out from the second refrigerant flow path 120 and the third refrigerant flow path 130 , both directly flow into the first inlet 114 .

[0038] In this embodiment, the cooling system is a liquid cooling system, that is, the cooling of the heat generating parts is achieved by circulating liquid refrigerant. The liquid refrigerant can be water, mineral oil, electronic fluorinated liquid, etc.

[0039] The cooling system of this embodiment can be a whole vehicle cooling system. A liquid-cooled in-vehicle entertainment host radiator 131 is set on the in-vehicle entertainment host 150, and the in-vehicle entertainment host radiator 131 is connected to the whole vehicle cooling system, and the whole vehicle cooling system is used to dissipate heat from the in-vehicle entertainment host 150. Specifically, the cooling system is provided with a first refrigerant flow path 110, a second refrigerant flow path 120 and a third refrigerant flow path 130, and the first refrigerant flow path 110 is provided with a pump group 111 and a heat exchanger 112 connected in series. The pump group 111 can be provided with one or more pumps for driving the liquid refrigerant to circulate in a refrigerant circuit composed of at least the first refrigerant flow path 110, the second refrigerant flow path 120 and the third refrigerant flow path 130. The heat exchanger 112 can be an air-cooled radiator, which is arranged upstream of the pump group 111, and is used to dissipate heat and cool the liquid refrigerant.

[0040] After the liquid refrigerant flows out of the pump group 111, it enters the second refrigerant flow path 120 and the third refrigerant flow path 130 which are arranged in parallel through the first outlet 113. Specifically, part of the liquid refrigerant enters the second refrigerant flow path 120 from the second inlet 122, flows through the brake control device radiator 121, dissipates heat for the brake control device 160, flows out through the second outlet 123, and then flows into the first refrigerant flow path 110 through the first inlet 114. Part of the liquid refrigerant enters the third refrigerant flow path 130 from the third inlet 132, flows through the in-vehicle entertainment host radiator 131, dissipates heat for the in-vehicle entertainment host 150, flows out through the third outlet 133, and then flows into the first refrigerant flow path 110 through the first inlet 114.

[0041] Compared with the prior art of air cooling or convection cooling of the vehicle entertainment host 150, the liquid refrigerant cooling system of the utility model has a higher heat dissipation efficiency and can more efficiently dissipate heat for the vehicle entertainment host 150. In particular, under the condition of high ambient temperature, the cooling system can dissipate heat and cool the vehicle entertainment host 150 more effectively.

[0042] Furthermore, the cooling system of the present invention can reduce the manufacturing cost of the in-vehicle entertainment host 150 and reduce the heat dissipation energy consumption of the in-vehicle entertainment host 150 because it does not need to additionally set a cooling fan on the in-vehicle entertainment host 150 .

[0043] On the other hand, the brake control device 160 has irregular heat dissipation during operation, and is prone to generate a large amount of heat in a very short time, resulting in a high load on the refrigerant flow path where it is located. In the cooling system of this embodiment, the second refrigerant flow path 120 and the third refrigerant flow path 130 are arranged in parallel, so that the brake control device radiator 121 and the vehicle entertainment host radiator 131 can work relatively independently, avoiding mutual interference between the brake control device radiator 121 and the vehicle entertainment host radiator 131 when they are working at high load at the same time, and realizing efficient heat dissipation of the brake control device 160 and the vehicle entertainment host 150 at the same time.

[0044] In some embodiments of the cooling system of the present invention, Figure 1 As shown, the cooling system further includes a detection device 140 and an in-vehicle entertainment host 150. The detection device 140 is configured to obtain at least one of a temperature parameter, a flow rate parameter, and a pressure parameter of the liquid refrigerant. The in-vehicle entertainment host 150 is electrically connected to the detection device 140 and the pump group 111 to control the operating state of the pump group 111 based on the parameters obtained by the detection device 140.

[0045] The detection device 140 can be one or more of a temperature sensor, a flow rate sensor, and a pressure sensor, which are used to detect the temperature parameter, flow rate parameter, and pressure parameter of the liquid refrigerant, respectively. The vehicle-mounted entertainment host 150 is provided with a thermal management system of the vehicle. The vehicle-mounted entertainment host 150 is electrically connected to the detection device 140 and the pump group 111 to obtain the detection result of the detection device 140 and control the operating state of the pump group 111. For example, when the temperature parameter of the liquid refrigerant is high, the operating power of the pump group 111 can be controlled to increase, the circulation speed of the liquid refrigerant can be increased, and thus the cooling capacity can be improved.

[0046] In particular, the in-vehicle entertainment host 150 can be provided with intelligent control technology to monitor and control the cooling system in real time, thereby improving the stability and reliability of the cooling system, ensuring the normal operation of the cooling system and increasing its service life.

[0047] In some embodiments of the cooling system of the present invention, Figure 1 As shown, the second refrigerant flow path 120 is also provided with a first refrigerant flow path heat exchanger 124, which is located downstream of the brake control device radiator 121 and can perform preliminary heat dissipation and cooling on the liquid refrigerant flowing through the brake control device radiator 121.

[0048] In some embodiments of the cooling system of the present invention, Figure 1 As shown, a three-way regulating valve 190 is also provided upstream of the first inlet 114. The three-way regulating valve 190 is used to merge the liquid refrigerant in the second refrigerant flow path 120 and the third refrigerant flow path 130, and can adjust the flow rate of the liquid refrigerant in the second refrigerant flow path 120 and the third refrigerant flow path 130 according to preset working conditions or according to the load, thereby further improving the cooling efficiency of the cooling system.

[0049] In some embodiments of the cooling system of the present invention, Figure 1 As shown, the third refrigerant flow path 130 is also provided with a motor radiator 134, and the motor radiator 134 is located upstream of the vehicle entertainment host radiator 131. Compared with the brake control device 160 and the motor, the vehicle entertainment host 150 generates less heat. If a refrigerant flow path is provided in the vehicle entertainment host 150 alone, it will cause a waste of parts and a waste of liquid refrigerant flow. Connecting the motor radiator 134 and the vehicle entertainment host radiator 131 in series on a refrigerant flow path can reduce the manufacturing cost without affecting the cooling needs of the motor and the vehicle entertainment host 150.

[0050] In some embodiments of the cooling system of the present invention, Figure 1As shown, the cooling system is also provided with a rectifying device 170, which is located downstream of the pump group 111 and can rectify the liquid refrigerant in the refrigerant flow path to reduce turbulence, thereby reducing bubbles. Preferably, a filter can also be provided in the rectifying device 170 to filter the liquid refrigerant in the refrigerant flow path and remove impurities to reduce or avoid pipeline blockage and improve cooling efficiency.

[0051] In some embodiments of the cooling system of the present invention, Figure 1 As shown, the cooling system is further provided with a pressure retaining tank device 180, which is located upstream of the second inlet 122 and the third inlet 132, and can stabilize the pressure of the liquid refrigerant in the refrigerant flow path, stabilize or increase the flow rate, thereby improving the cooling efficiency.

[0052] In some embodiments of the cooling system of the present invention, Figure 2-3 As shown, the vehicle entertainment host radiator 131 includes a liquid cooling head 500 , and a liquid cavity 530 is arranged inside the liquid cooling head 500 .

[0053] The liquid passage cavity 530 is in communication with the third inlet 132 through the liquid inlet channel 510 , and the liquid passage cavity 530 is in communication with the third outlet 133 through the liquid outlet channel 520 .

[0054] In this embodiment, the liquid cooling head 500 may include a shell 550, and the shell 550 may be a metal with good thermal conductivity. One or more surfaces of the shell 550 are in contact with the processor of the vehicle entertainment host 150, or in contact with the heat conductive part of the processor of the vehicle entertainment host 150, so that the heat generated by the processor when working is quickly transferred to the shell 550. The liquid cavity 530 is connected in series to the third refrigerant flow path 130. When the liquid refrigerant flows through the liquid cavity 530, it can absorb the heat of the shell 550, thereby achieving heat dissipation and cooling of the shell 550 and the processor of the vehicle entertainment host 150.

[0055] In this embodiment, the shell 550 may be in the shape of a plate as a whole, or the shell 550 may be formed by merging and splicing two front and rear metal plates with grooves on opposite surfaces. Accordingly, the front and rear side walls of the liquid cavity 530 have a larger area, that is, the liquid refrigerant in the liquid cavity 530 has a larger contact surface with the shell 550, so that the liquid refrigerant can fully absorb and transfer the heat of the shell 550.

[0056] In some embodiments of the cooling system of the present invention, Figure 2-3As shown, the liquid outlet channel 520 is located on the upper side of the liquid inlet channel 510. With such a configuration, on the one hand, the bubbles that may be in the liquid cavity 530 can rise under buoyancy and flow out from the liquid outlet channel 520, thereby improving the cooling efficiency of the liquid cooling head 500. On the other hand, the existing liquid refrigerant usually forms temperature stratification. After the liquid refrigerant absorbs the heat of the shell 550 in the liquid cavity 530, it rises under the action of buoyancy, which can reduce the flow resistance, that is, reduce the power consumption of the pump group 111.

[0057] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid passage cavity 530 extends along a U-shaped curve, and the liquid inlet channel 510 and the liquid outlet channel 520 are respectively located at two ends of the liquid passage cavity 530 .

[0058] The processor of the vehicle entertainment host 150 is usually small in size. Setting the liquid cavity 530 as a U-shaped curve can increase the length of the path of the liquid cavity 530 under the same volume, so that the liquid refrigerant in the liquid cavity 530 can fully contact the shell 550, take away the heat of the shell 550, and improve the cooling efficiency.

[0059] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid passage cavity 530 includes a first flow channel cavity 531, a second flow channel cavity 532 and a third flow channel cavity 533. One end of the first flow channel cavity 531 is connected to the liquid inlet channel 510. The second flow channel cavity 532 is arranged in parallel and spaced apart from the first flow channel cavity 531, and one end of the second flow channel cavity 532 is directly or indirectly connected to the liquid outlet channel 520. The third flow channel cavity 533 is arc-shaped, and one end of the third flow channel cavity 533 is connected to one end of the first flow channel cavity 531 away from the liquid inlet channel 510, and the other end of the third flow channel cavity 533 is connected to one end of the second flow channel cavity 532 away from the liquid outlet channel 520.

[0060] In this embodiment, the first flow channel cavity 531 and the second flow channel cavity 532 are arranged in parallel and spaced apart, and the liquid refrigerant flows in opposite directions in the first flow channel cavity 531 and the second flow channel cavity 532. The third flow channel cavity 533 is arc-shaped, which, on the one hand, guides the liquid refrigerant to turn here, and on the other hand, can smooth the flow rate of the liquid refrigerant when turning, avoiding excessive flow rate stratification in the lateral direction, resulting in turbulence and bubbles.

[0061] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the cross section of the third flow channel cavity 533 is larger than the cross section of the first flow channel cavity 531. When the liquid refrigerant turns in the third flow channel cavity 533, the flow velocity will decrease. By increasing the cross section of the third flow channel cavity 533 accordingly, the liquid refrigerant can flow through the third flow channel cavity 533 at a slower flow velocity under the same flow rate, thereby reducing the generation of turbulence and bubbles.

[0062] In some embodiments of the cooling system of the present invention, Figure 2-3 As shown, the liquid inlet channel 510 is parallel to the liquid outlet channel 520. The included angle b between the extension direction of the first flow channel cavity 531 and the liquid inlet channel 510 is 90 degrees to 145 degrees.

[0063] In this embodiment, the liquid inlet channel 510 and the liquid outlet channel 520 are arranged in parallel, which is convenient for opening the mold, manufacturing the liquid inlet and the liquid outlet, and also convenient for installing the quick-connect plugs of the refrigerant pipe at the liquid inlet and the liquid outlet.

[0064] Under vehicle-mounted conditions, the liquid cooling head 500 may have more and larger vibrations or shakes, which may easily cause irregular shaking and reflux of the liquid refrigerant in the liquid passage cavity 530, thereby affecting the cooling efficiency. In this embodiment, the angle is set to 90 degrees to 145 degrees, so that after the liquid refrigerant flows into the liquid inlet channel 510, it quickly turns and enters the first flow channel cavity 531, avoiding the accumulation of liquid refrigerant in the liquid inlet channel 510, thereby reducing the reflux into the liquid inlet channel 510 during vibration or shaking.

[0065] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid passage cavity 530 further includes a fourth flow channel cavity 534 , and two ends of the fourth flow channel cavity 534 are respectively connected to the second flow channel cavity 532 and the liquid outlet channel 520 .

[0066] In this embodiment, the fourth flow channel cavity 534 may have an arc-shaped flow channel, which can redirect and guide the liquid refrigerant flowing out of the second flow channel cavity 532 to enter the liquid outlet channel 520 .

[0067] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid outlet channel 520 is located at the upper end of the corresponding end of the fourth flow channel cavity 534. In this way, the liquid refrigerant with a relatively high temperature in the upper part of the fourth flow channel cavity 534 can flow out from the liquid outlet channel 520 first, so that the liquid refrigerant with a relatively low temperature in the lower part of the fourth flow channel cavity 534 has sufficient time to continue to absorb the heat of the shell 550, rise to the upper part of the fourth flow channel cavity 534 after heating, and then flow out from the liquid outlet channel 520. The cooling efficiency of the liquid cooling head 500 can be further improved.

[0068] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid cooling head 500 further includes a first guide rib 541, which is located in the first flow channel cavity 531 and parallel to the extension direction of the first flow channel cavity 531. There are at least two first guide ribs 541 spaced apart in a vertical direction along the extension direction of the first flow channel cavity 531, and are located along one side of the first flow channel cavity 531 close to the second flow channel cavity 532 and the third flow channel cavity 533.

[0069] In this embodiment, the first guide rib 541 guides the liquid refrigerant in the first flow channel cavity 531. Figure 3 As shown, the first guide rib 541 is located at Figure 3 The first guide rib 541 can guide the liquid refrigerant of the first flow channel cavity 531 that is about to enter the third flow channel cavity 533 and is close to the arc center of the third flow channel cavity 533. On the one hand, the amount of liquid refrigerant entering the third flow channel cavity 533 close to the arc center can be reduced, thereby reducing the flow rate of the liquid refrigerant close to the arc center of the third flow channel cavity 533. On the other hand, the amount of liquid refrigerant entering the third flow channel cavity 533 away from the arc center can be increased, thereby increasing the flow rate of the liquid refrigerant away from the arc center of the third flow channel cavity 533. In other words, the liquid refrigerant at various locations of the third flow channel cavity 533 forms a flow rate and centrifugal force that is adapted to its position, reducing or avoiding the lateral flow of the liquid refrigerant in the third flow channel cavity 533, thereby reducing or avoiding the generation of turbulence and bubbles, which affects the cooling efficiency of the liquid cooling head 500.

[0070] The first guide rib 541 can also increase the total area of ​​the inner wall of the liquid cavity 530 , so that the liquid refrigerant is fully in contact with the shell 550 , thereby improving the cooling efficiency of the liquid cooling head 500 .

[0071] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid cooling head 500 further includes a second guiding rib 542, and the second guiding rib 542 is parallel to the extension direction of the second flow channel cavity 532. There are multiple second guiding ribs 542, and they are arranged in the second flow channel cavity 532 in an array along the extension direction of the second flow channel cavity 532 and in a vertical direction along the extension direction of the first flow channel cavity 531.

[0072] In this embodiment, the second guide ribs 542 can be arranged in an array throughout the second flow channel cavity 532 to guide the liquid refrigerant in the second flow channel cavity 532, thereby improving the flow uniformity of the liquid refrigerant, reducing or avoiding the lateral flow of the liquid refrigerant in the third flow channel cavity 533, and thereby reducing or avoiding the generation of turbulence and bubbles that affect the cooling efficiency of the liquid cooling head 500.

[0073] The second guide ribs 542 can also increase the total area of ​​the inner wall of the liquid cavity 530 , so that the liquid refrigerant is fully in contact with the shell 550 , thereby improving the cooling efficiency of the liquid cooling head 500 .

[0074] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the liquid cooling head 500 further includes a third guiding rib 543, which is arc-shaped. There are multiple third guiding ribs 543, which are co-centered and radially spaced in the third flow channel cavity 533.

[0075] In this embodiment, the second guide rib 542 can guide the liquid refrigerant in the third flow channel cavity 533, improve the flow uniformity of the liquid refrigerant, reduce or avoid the lateral flow of the liquid refrigerant in the third flow channel cavity 533, and further reduce or avoid the generation of turbulence and bubbles, which affect the cooling efficiency of the liquid cooling head 500. On the other hand, it can provide centripetal force to the liquid refrigerant turning at the third flow channel cavity 533, so as to promote its turning.

[0076] The third guide rib 543 can also increase the total area of ​​the inner wall of the liquid cavity 530 , so that the liquid refrigerant is fully in contact with the shell 550 , thereby improving the cooling efficiency of the liquid cooling head 500 .

[0077] In some embodiments of the cooling system of the present invention, Figure 3 As shown, a plurality of third guide ribs 543 are evenly spaced radially in the third flow channel cavity 533. There are N third guide ribs 543, of which at least the inner M third guide ribs 543 have the same central angle a and are all in a sector area with the central angle a.

[0078] In this embodiment, N=5, M=4, and the central angle a is about 75 degrees. Five third guide ribs 543 are evenly spaced radially in the third flow channel cavity 533, wherein the four third guide ribs 543 near the center of the circle have the same central angle of 75 degrees, and are all in the fan-shaped area with a central angle of 75 degrees. In this way, the guiding effect of the third guide rib 543 on the liquid refrigerant can be further improved, the flow rate and direction of the liquid refrigerant can be guided, and turbulence and bubbles generated by the liquid refrigerant when turning can be further reduced or avoided.

[0079] In some embodiments of the cooling system of the present invention, Figure 3 As shown, a plurality of third guide ribs 543 are evenly spaced radially in the third flow channel cavity 533. The connecting line of one end of all the third guide ribs 543 facing the liquid inlet channel 510 is a straight line passing through the center of the third guide ribs 543. In this way, the guiding effect of the third guide ribs 543 on the liquid refrigerant can be further improved, the flow rate and flow direction of the liquid refrigerant can be guided, and turbulence and bubbles generated by the liquid refrigerant when turning can be further reduced or avoided.

[0080] In some embodiments of the cooling system of the present invention, Figure 3As shown, the liquid cooling head 500 further includes a fourth guide rib 544, which is located at the junction of the third flow channel cavity 533 and the second flow channel cavity 532. There are multiple fourth guide ribs 544, which are arranged at intervals. The extension direction of the fourth guide rib 544 is the flow direction of the liquid refrigerant at this location, which can guide the liquid refrigerant at this location, improve the flow uniformity of the liquid refrigerant, reduce or avoid the lateral flow of the liquid refrigerant at this location, and further reduce or avoid the generation of turbulence and bubbles, which affect the cooling efficiency of the liquid cooling head 500.

[0081] In some embodiments of the cooling system of the present invention, Figure 3 As shown, the first guide rib 541, the third guide rib 543 and the fourth guide rib 544 are through-hole structures. Specifically, the through-holes penetrate the shell 550 from the front and rear side walls of the shell 550, and the hole walls of the through-holes form the first guide rib 541, the third guide rib 543 and the fourth guide rib 544. Such a design, on the one hand, facilitates the production and processing of the shell 550, and on the other hand, can further increase the wall area of ​​the first guide rib 541 and the third guide rib 543, that is, increase the contact area between the liquid coolant and the inner wall of the shell 550, and improve the cooling efficiency of the liquid cooling head 500.

[0082] In some embodiments of the cooling system of the present invention, Figure 2-3 As shown, the liquid cooling head 500 also includes a shell 550 and an exhaust structure (not shown in the figure), the liquid cavity 530 is located in the shell 550, one end of the exhaust structure is connected to the liquid cavity 530, and the other end of the exhaust structure passes through the shell 550 to discharge the gas in the liquid cavity 530.

[0083] The exhaust structure can make the gas in the liquid cavity 530 escape more easily, thereby reducing the generation of bubbles. The number and position of the exhaust structure should be designed according to actual conditions to ensure the ventilation effect without affecting the overall structure of the liquid cavity 530.

[0084] In some embodiments of the cooling system of the present invention, the liquid refrigerant is composed of water and a surfactant, etc. The surfactant can reduce the surface tension of the liquid refrigerant and allow the gas to escape more easily, thereby reducing the generation of bubbles.

[0085] In some embodiments of the cooling system of the present invention, the vehicle entertainment host 150 is sprayed with a three-proof paint to prevent the liquid cooling head 500 from leaking, or even if it leaks, it will not contact the circuits and wires of the vehicle entertainment host 150.

[0086] On the other hand, the utility model provides a vehicle, such as Figure 4 As shown, the vehicle includes a vehicle body 200 and the above-mentioned cooling system.

[0087] Exemplarily, the vehicle body 200 includes a front interior metal frame, the vehicle entertainment host 150 is fixedly connected to the front interior metal frame, and the vehicle entertainment host radiator 131 is located inside the vehicle entertainment host 150. The liquid inlet and the liquid outlet are formed at the liquid inlet channel 510 and the liquid outlet channel 520, respectively, and are connected to the pipeline of the cooling system through a quick plug connector. The quick plug connector is convenient for installation and removal, and even if it is damaged, it is easy to quickly plug and unplug.
