[0038] See also Figures 1 to 3 , shown is a display screen heat dissipation system in an embodiment of the present invention, including a cylinder 10, an air guide assembly 20, a drive assembly 30, an air outlet assembly 40, a heat dissipation assembly 50 and a circulating cooling assembly 60.

[0039] The cylinder 10 is symmetrically provided with openings 11 on both sides, the air guide assembly 20 is arranged in the cylinder 10, the driving assembly 30 is arranged at the bottom of the cylinder 10, the output end of the driving assembly 30 is connected to the air guide assembly 20, the air outlet assembly 40 is arranged on one side of the driving assembly 30, and the output end of the air outlet assembly 40 is connected to the cylinder 10 via the driving assembly 30, the heat dissipation assembly 50 is provided with two groups, the two heat dissipation assemblies 50 are arranged on both sides of the cylinder 10 and correspond to the positions of the openings 11, and the two heat dissipation assemblies 50 include a heat absorption portion 51 and The heat conducting part 52 is arranged on the heat absorbing part 51, and the circulating cooling component 60 is provided with two groups, and the two circulating cooling components 60 are respectively connected to the two heat conducting parts 52, wherein the driving component 30 drives the air guide component 20 to rotate so that the wind blown out by the air outlet component 40 passes through the air guide component 20 and is guided to the two heat dissipation components 50 through the opening 11 on the cylinder 10, and the multi-screen is cooled by the heat absorbing part 51 and the heat conducting part 52, and the fluid cold source in the circulating cooling component 60 cools the heat conducting part 52 and the heat absorbing part 51.

[0040] It can be understood that the wind blown out by the air outlet component 40 reaches the cylinder 10 through the driving component 30. At this time, the air guide component 20 is driven to rotate by the driving component 30, so that the air guide component 20 can introduce the wind blown out by the air outlet component 40 into the two heat dissipation components 50 through the opening 11. Since the system is arranged at the bottom of the multi-screen, the heat absorption part 51 and the heat conduction part 52 on the heat dissipation component 50 can dissipate heat for the multi-screen. In addition, the fluid cold source is introduced into the heat conduction part 52 through the circulating cooling component 60, so as to cool the heat conduction part 52. Since the heat absorption part 51 is arranged on the heat conduction part 52, the heat conduction part 52 can further cool the heat absorption part 51. In this embodiment, the fluid cold source is a coolant or a fluid refrigerant. It is worth noting that the circulating cooling component 60 can be connected to the coolant circuit of the vehicle air conditioner to extract part of the cold source in the cooling state therefrom.

[0041] It is worth noting that the heat absorbing part 51 includes a plurality of heat-conducting metal strips 510, and the plurality of heat-conducting metal strips 510 are radially arranged. The heat-conducting part 52 includes a plurality of channels 520, and the plurality of channels 520 are bent and interconnected. The plurality of channels 520 are in contact with and cover the heat absorbing part 51, and the arrangement density of the plurality of channels 520 on the heat absorbing part 51 along the radial direction of the heat absorbing part 51 is from large to small.

[0042] It should be explained that the heat-conducting metal strips 510 are made of a material with a large heat absorption coefficient, and a plurality of heat-conducting metal strips 510 are radially arranged toward the center of the multi-screen on both sides, and the heat-conducting metal strips 510 have a certain direction, so that they can occupy more internal space of the display screen, and secondly, the absorbed heat can be directed along its own axial direction to a certain place, so that the heat can be released in a directionally manner;

[0043] The channel 520 is connected to the circulating cooling component 60, so that the fluid cold source in the circulating cooling component 60 enters the channel 520, so that the channel 520 is cooled down and the temperature of the heat-conducting metal strip 510 is reduced to further improve the heat dissipation effect. In addition, the circulating cooling component 60 can be connected to the coolant circuit of the vehicle air conditioner to extract part of the cold source in the cooling state.

[0044] It is worth mentioning that the radially arranged heat-conducting metal strips 510 are adapted to the positional relationship between the cooling source and the heat source, which is conducive to establishing a heat dissipation channel. The radial arrangement is conducive to covering various heat-generating components in the center of the display screen and improving the heat dissipation effect. Secondly, the radial arrangement is conducive to the diversion of heat dissipation wind. When the wind passes through the radial channel formed by the heat-conducting metal strips 510, the flow rate and pressure of the wind are increased, which is conducive to improving the heat dissipation effect. The gathered air inlet position is also conducive to the gathering of cold sources to avoid meaningless dissipation.

[0045] In addition, the arrangement density of the channels 520 changes from sparse to gradually dense as the radial metal heat-conducting strips 510 move from the dense end to the radial end.

[0046] In other optional embodiments, the heat-conducting metal strip 510 is wavy or string-shaped, which can increase the suction area according to the shape of the display screen.

[0047] Specifically, in the present embodiment, the air guide assembly 20 includes a rotating shaft 21, a plurality of scrapers 22 and a plurality of fixed plates 23. The rotating shaft 21 is arranged in the cylinder 10, one end of the rotating shaft 21 is connected to the output end of the driving assembly 30, a plurality of scrapers 22 are evenly fixed on the side wall of the rotating shaft 21, a plurality of fixed plates 23 are evenly fixed on the side wall of the rotating shaft 21, the side wall of the fixed plate 23 is connected to a compression plate 25 through a spring 24, the spring 24 is arranged at the four corners of the compression plate 25, and a sealing strip 26 is provided at the contact portion between the compression plate 25 and the inner wall of the cylinder 10.

[0048] It can be understood that the scraper 22 can drive the wind in the cylinder 10, that is, the wind generated by the air outlet component 40, so that the wind generated by the air outlet component 40 enters the heat dissipation component through the opening 11 on the cylinder 10, and the contact portion between the compression plate 25 and the inner wall of the cylinder 10 is provided with a sealing strip 26, and the compression plate 25 is connected to the fixing plate 23 through the spring 24, so that the wind in the cylinder 10 can be fully utilized.

[0049] It is worth mentioning that the scraper 22 can also discharge air when rotating to achieve the effect of air cooling. The compression plate 25 rubs against the inner wall of the cylinder 10 during rotation to compress the air space. When it rotates to the opening 11, the compressed air is released to form a larger momentum of air volume, making the heat dissipation effect more outstanding.

[0050] Specifically, in this embodiment, the driving assembly 30 includes a connecting part 31 and a rotating motor 32. The connecting part 31 is arranged at the bottom of the cylinder 10, and the connecting part 31 is communicated with the cylinder 10. The rotating motor 32 is arranged on the connecting part 31. The rotating motor 32 is used to drive the connecting part 31 to rotate. The wind guide assembly 20 is provided on the top of the connecting part 31.

[0051] It can be understood that the rotating motor 32 drives the connecting part 31 to rotate, and the top of the connecting part 31 is provided with a rotating shaft 21 of the wind guide assembly 20, so that the rotating shaft 21 can rotate, and then the rotating shaft 21 drives the scraper 22, the fixed plate 23 and the compression plate 25 to rotate, so that the wind in the cylinder 10 is introduced into the heat dissipation assembly 50 through the opening 11.

[0052] Specifically, in this embodiment, the air outlet component 40 includes a fan 41 and an air inlet pipe 42, one end of the air inlet pipe 41 is connected to the air outlet end of the fan 40, and the other end of the air inlet pipe 42 is connected to the side wall of the drive component 30 and communicates with the drive component 30.

[0053] It should be explained that one end of the air inlet pipe 42 passes through the bottom side wall of the connecting portion 31, and the connecting portion 31 is connected to the cylinder 10, so when the wind generated by the fan 40 enters the connecting portion 31 through the air inlet pipe 42, it enters the cylinder 10 through the connecting portion 31;

[0054] It is worth noting that the connecting portion 31 is divided into two parts. The part with the rotating shaft 21 on the top will be driven by the rotating motor 32, while the bottom is fixed, and the top of the connecting portion 31 is rotatably arranged on the bottom.

[0055] In other embodiments, the air inlet end of the air inlet pipe 42 can be connected to the air-conditioning outlet duct in the vehicle center console so that the refrigerated air-conditioning air can be used to dissipate heat and cool the display screen.

[0056] Specifically, in the present embodiment, the two circulating cooling components 60 each include a cold source container 61 and an injection cavity 62, the cold source container 61 is disposed below the heat dissipation component 50, the outlet of the heat conducting portion 52 is connected to the cold source container 61, the injection cavity 62 is disposed above the cold source container 61, and the top and bottom of the injection cavity 62 are both provided with a one-way valve 621, the one-way valve 621 at the top is connected to the heat conducting portion 52, and the one-way valve 621 at the bottom is connected to the cold source container 61, the injection cavity 62 is a flexible variable cavity, and a plurality of protrusions 310 are provided on the outer wall of the driving component 30 at even intervals, and a plurality of the protrusions 310 are provided in contact with the injection cavity 62.

[0057] It should be explained that the cold source container 61 is arranged below the heat absorbing part 51 and the heat conducting part 52, and a plurality of protrusions 310 are evenly spaced and arranged on the side wall of the top of the connecting part 31, that is, the rotatable part of the connecting part 31.

[0058] It can be understood that when the connecting portion 31 rotates, the connecting portion 31 drives the plurality of protrusions 310 to rotate, so that the protrusions 310 arranged at intervals contact the outer wall of the flexible and variable injection cavity 62, and squeeze the injection cavity 62, resulting in a change in the volume of the injection cavity 62, so that the refrigerant stored inside is discharged or inhaled, wherein the refrigerant is injected into the channel 520 through the one-way valve 621 at the top, thereby achieving a further heat dissipation effect, and the refrigerant in the cold source container 61 can only enter the injection cavity 62 through the one-way valve 621 at the bottom, and the refrigerant in the injection cavity 62 cannot be discharged from the cold source container at the bottom;

[0059] It should be explained that the protrusions 310 are arranged at intervals so that when one protrusion 310 contacts the injection cavity 62, the injection cavity 62 on the other side does not contact the protrusion 310, that is, it is located between the two protrusions 310, so as to achieve asynchronous driving of the left and right refrigerants, ensure sufficient refrigerant for alternating heat dissipation of the single-sided display screen, and achieve better heat dissipation effect. The outlet 520 is connected to the cold source container 61, and the refrigerant that has undergone heat exchange can be returned to the cold source container 61 for re-cooling.

[0060] In summary, the display screen heat dissipation system in the above-mentioned embodiment of the present invention guides the wind generated by the blowing component 40 to the heat dissipation component 50 through the wind guide component 20, so as to improve the heat dissipation effect of the heat dissipation component 50 on the display screen, and because the system is arranged at the bottom of the multi-screen, the space of the multi-screen can be effectively utilized, and the heat dissipation component is cooled by the fluid cold source of the circulating cooling component 60, so as to further improve the heat dissipation effect of the display screen.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
