[0001] The invention relates to an air-conditioning aluminum sheet, and in particular to an automobile air-conditioning aluminum sheet with self-regulating thermal interaction performance, which is applied in the field of air-conditioning aluminum sheets. Background Art

[0002] Microchannel aluminum flat tube is a thin-walled porous flat tubular material made of refined aluminum rods through hot extrusion and surface zinc spraying for corrosion protection. It is mainly used in air-conditioning systems of various refrigerants, such as the refrigeration system of new energy vehicles. There are through holes inside the aluminum flat tube, and the air-conditioning liquid dissipates heat through the through holes.

[0003] After searching, the Chinese invention patent with publication number CN116358336A discloses a porous microchannel aluminum flat tube for new energy vehicles, including a tube body, in which a plurality of groups of partitions are fixedly provided, and a channel is formed between two adjacent partitions, and a plurality of groups of heat dissipation connecting sheets and heat dissipation connecting plates are fixedly provided on the top and bottom of the tube body respectively.

[0004] Based on the above search, combined with the prior art, it is found that the above patent still has the following deficiencies: in the process of heat dissipation and heat exchange of the aluminum flat tube, it does not have the function of automatically adjusting the heat dissipation of the aluminum flat tube, and the entire aluminum flat tube has poor structural strength and is prone to damage and leakage. Therefore, a thermal interaction performance self-adjusting automobile air conditioning aluminum sheet is proposed to improve the above problems. Summary of the invention

[0006] In order to solve the above problems, the present invention provides an automobile air-conditioning aluminum sheet with self-adjusting thermal interaction performance, comprising:

[0007] An aluminum plate, wherein a microporous channel component is disposed inside the aluminum plate;

[0008] The microporous channel assembly includes a main channel, a first semicircular channel, a second semicircular channel, a third semicircular channel and an adjustment channel arranged inside the aluminum plate, the main channels are staggered up and down inside the aluminum plate, and the cross section of the main channels is a regular hexagon;

[0009] The inner diameter of the first semicircular channel is larger than that of the second semicircular channel. A first baffle is fixedly connected inside the first semicircular channel. The number of the first baffles is two groups. The two groups of the first baffles and the first semicircular channel and the second semicircular channel form a first concentration area.

[0010] A second partition is disposed inside the third semicircular channel, and the second partition and the third semicircular channel form a second concentration area;

[0011] A positioning groove is provided at one end of the adjustment channel, and an adjustment component is arranged inside the positioning groove;

[0012] A reset component is arranged inside the regulating component. The aluminum plate ensures the flow rate of coolant in the entire aluminum plate through the microporous channel component arranged inside the aluminum plate. At the same time, the main channel cross-section in the microporous channel component is a regular hexagon and is staggered, so that the interior of the entire aluminum plate has a honeycomb structure, which not only avoids the blockage of the microporous channel component, but also ensures the strength of the entire aluminum plate, and does not cause damage and leakage due to poor structural strength.

[0013] In the above, the outer wall of the aluminum plate is fixedly connected with an extension part, a thin plate is arranged on the side of the extension part away from the aluminum plate, one end of the thin plate away from the extension part is fixedly connected to the other extension part, two groups of the aluminum plates are fixedly connected through the extension part and the thin plate, and the outer walls on both sides of the thin plate are fixedly connected with equidistantly distributed heat dissipating fins, and the cross-section of the heat dissipating fins is V-shaped.

[0014] As a further supplement to the present application, the heat absorbed by the first concentrated area and the second concentrated area 4 can be quickly discharged through heat exchange through the extension part. At the same time, the outer wall of the thin plate on one side of the extension part is fixed with equidistantly distributed heat dissipation fins, which can accelerate the heat exchange between the first concentrated area and the second concentrated area.

[0015] As another improvement of the present application, the adjusting assembly includes an outer ring plate fixedly connected to the inside of the positioning groove, an outer wall of one side of the outer ring plate is fixedly connected to an inner tube, the inner tube is arranged in the inside of the adjusting channel, a movable tube is arranged inside the inner tube, the circumferential outer wall of the movable tube is provided with through grooves distributed in a circular shape with equal distances, the width of the through grooves gradually decreases in the direction away from the outer ring plate, a ramp end is provided at one end of the movable tube, the through groove extends to the end of the ramp end, an extension rod distributed in a circular shape with equal distances is fixedly connected to the circumferential inner wall of one end of the movable tube away from the ramp end, an end of the extension rod away from the inner wall of the movable tube is fixedly connected to a circular plate, one end of the inner tube is fixedly connected to a convex plate, a guide column is fixedly connected to an outer wall of one side of the convex plate, one end of the guide column passes through one side of the extension rod, one end of the guide column is fixedly connected to a limiting cap, and guide grooves are provided on the outer walls of both sides of the extension rod, and the cross-section of the guide groove is wavy.

[0016] As another improvement supplement of the present application, it is possible to automatically adjust the coolant flow rate of the microporous channel assembly inside the aluminum plate. When the heat dissipation demand is large, the coolant flow rate can be increased. At this time, the coolant hydraulic pressure flowing into the inner tube will also increase relatively. When the hydraulic pressure inside the inner tube increases, it can continuously provide horizontal thrust to the circular plate. When the circular plate is subjected to the horizontal thrust, it will drive the entire movable tube to move out from one end of the inner tube. During the process of the inner tube moving out, the exposed through groove length will also become longer, thereby increasing the coolant flow rate in the entire adjustment channel, enhancing the heat dissipation performance of the entire aluminum plate, and realizing self-regulation of the heat dissipation of the aluminum plate. The width of the entire through groove gradually decreases in the direction away from the outer ring plate, thereby further increasing the coolant flow rate in the adjustment channel.

[0017] As another improvement of the present application, the reset assembly includes a bent rod portion fixedly connected to the circumferential inner wall of the inner tube, an end of the bent rod portion away from the inner tube is fixedly connected to a straight rod portion, one end of the straight rod portion is fixedly connected to a positioning plate, one side outer wall of the positioning plate is fixedly connected to a spring, one end of the spring away from the positioning plate is fixedly connected to one side outer wall of the slope end, and the circumferential outer wall of the bent rod portion is provided with drainage grooves distributed in a circular shape and at equal distances.

[0018] As another improvement supplement to the present application, the flow rate of the coolant can be reduced when the staff's demand for cooling decreases. At this time, the spring in a compressed state on one side of the positioning plate will immediately reset, thereby applying a reverse thrust to the movable tube, so that the movable tube can quickly reset to reduce the flow rate of the coolant inside the adjustment channel. The entire adjustment process can be achieved by adding or subtracting the flow rate of the coolant inside the aluminum plate, thereby meeting people's usage needs.

[0019] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0020] 1. The above-mentioned microporous channel assembly is used to ensure the flow of coolant in the entire aluminum plate. At the same time, the main channel cross-section in the microporous channel assembly is a regular hexagon and is staggered, so that the entire aluminum plate has a honeycomb structure inside, which not only avoids the blockage of the microporous channel assembly, but also ensures the strength of the entire aluminum plate, and will not cause damage and leakage due to poor structural strength.

[0021] 2. By adopting the above-mentioned adjustment component, the coolant flow rate of the microporous channel component inside the aluminum plate can be automatically adjusted. When the heat dissipation demand is large, the coolant flow rate can be increased. At this time, the coolant hydraulic pressure flowing into the inner tube will also increase relatively. When the hydraulic pressure inside the inner tube increases, it can continuously provide horizontal thrust to the circular plate. When the circular plate is subjected to horizontal thrust, it will drive the entire movable tube to move out from one end of the inner tube. In the process of the inner tube moving out, the exposed through groove length will also be longer, thereby increasing the coolant flow rate in the entire adjustment channel, enhancing the heat dissipation performance of the entire aluminum plate, and realizing self-regulation of heat dissipation of the aluminum plate. The width of the entire through groove gradually decreases in the direction away from the outer ring plate, thereby further increasing the coolant flow rate in the adjustment channel.

[0022] 3. By adopting the above-mentioned reset component, the flow rate of the coolant can be reduced when the staff's demand for cooling decreases. At this time, the spring in a compressed state on one side of the positioning plate will be reset immediately, thereby applying a reverse thrust to the movable tube, so that the movable tube can be quickly reset to reduce the flow rate of the coolant inside the adjustment channel. The entire adjustment process can be achieved by adding or subtracting the coolant flow rate inside the aluminum plate, which meets people's usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0043] A reset component 8 is provided inside the adjustment component 7. Figure 5 As shown, the aluminum plate 1 ensures the flow rate of the coolant in the entire aluminum plate 1 by means of the microporous channel assembly 4 arranged inside it. At the same time, the main channel 4004 in the microporous channel assembly 4 has a regular hexagonal cross-section and is staggered, so that the entire aluminum plate 1 has a honeycomb structure inside, which not only avoids the blockage of the microporous channel assembly 4, but also ensures the strength of the entire aluminum plate 1, and does not cause damage or leakage due to poor structural strength.

[0044] In the present invention, the outer wall of the aluminum plate 1 is fixedly connected with an extension 2, a thin plate 5 is arranged on the side of the extension 2 away from the aluminum plate 1, and one end of the thin plate 5 away from the extension 2 is fixedly connected to the other extension 2, and two groups of aluminum plates 1 are fixedly connected through the extension 2 and the thin plate 5, and the outer walls on both sides of the thin plate 5 are fixedly connected with equidistantly distributed heat dissipation fins 6, and the cross section of the heat dissipation fins 6 is V-shaped, such as Figure 1-Figure 2 As shown, the heat absorbed by the first concentrated area 4009 and the second concentrated area 4010 can be quickly discharged through heat exchange through the extension portion 2. At the same time, the outer wall of the thin plate 5 on one side of the extension portion 2 is fixed with equidistantly distributed heat dissipating fins 6, which can accelerate the heat exchange between the first concentrated area 4009 and the second concentrated area 4010.

[0045] In the present invention, the adjustment component 7 includes an outer ring plate 7002 fixedly connected to the inside of the positioning groove 4007, an inner tube 7001 is fixedly connected to the outer wall of one side of the outer ring plate 7002, the inner tube 7001 is arranged inside the adjustment channel 4008, a movable tube 7005 is arranged inside the inner tube 7001, and the circumferential outer wall of the movable tube 7005 is provided with through grooves 7007 distributed in a circular shape at equal distances, the width of the through grooves 7007 gradually decreases in the direction away from the outer ring plate 7002, one end of the movable tube 7005 is provided with a slope end 7006, the through groove 7007 extends to the end of the slope end 7006, and the movable tube 7005 is provided with a slope end 7006. The inner wall of the circumference of one end away from the slope end 7006 is fixedly connected with extension rods 7009 distributed in a circle at equal distances. The end of the extension rod 7009 away from the inner wall of the movable tube 7005 is fixedly connected with a circular plate 7008. One end of the inner tube 7001 is fixedly connected with a convex plate 7003. One side outer wall of the convex plate 7003 is fixedly connected with a guide column 7004. One end of the guide column 7004 passes through one side of the extension rod 7009. One end of the guide column 7004 is fixedly connected with a limiting cap 7011. The outer walls of both sides of the extension rod 7009 are provided with guide grooves 7010. The cross section of the guide groove 7010 is wavy, as shown in FIG. Figure 6-Figure 8 As shown, when the heat dissipation demand is large, the flow rate of the coolant can be increased. At this time, the hydraulic pressure of the coolant flowing into the inner tube 7001 will also increase relatively. When the hydraulic pressure inside the inner tube 7001 increases, it can continuously provide horizontal thrust to the circular plate 7008. When the circular plate 7008 is subjected to the horizontal thrust, it will drive the entire movable tube 7005 to move out from one end of the inner tube 7001. In the process of the inner tube 7001 moving out, the length of the exposed through groove 7007 will also become longer, thereby increasing the flow rate of the coolant in the entire adjustment channel 4008, enhancing the heat dissipation performance of the entire aluminum plate 1, and realizing the self-regulation of the heat dissipation of the aluminum plate 1. The width of the entire through groove 7007 gradually decreases in the direction away from the outer ring plate 7002, thereby further increasing the flow rate of the coolant in the adjustment channel 4008.

[0046] In summary, the working principle of the first embodiment is as follows: the aluminum plate 1 ensures the flow of coolant in the entire aluminum plate 1 by means of the microporous channel assembly 4 arranged inside the aluminum plate 1. At the same time, the main channel 4004 in the microporous channel assembly 4 is in a regular hexagonal cross section and is staggered, so that the entire aluminum plate 1 has a honeycomb structure inside, which not only avoids the blockage of the microporous channel assembly 4, but also ensures the strength of the entire aluminum plate 1, and does not cause damage and leakage due to poor structural strength. At the same time, the staff can automatically adjust the coolant flow rate of the microporous channel assembly 4 inside the aluminum plate 1. When the heat dissipation demand is large, the coolant flow rate can be increased. At this time, the coolant flowing into the inner tube 700 1, the hydraulic pressure of the coolant inside will also increase relatively. When the hydraulic pressure inside the inner tube 7001 increases, it can continuously provide horizontal thrust to the circular plate 7008. When the circular plate 7008 is subjected to the horizontal thrust, it will drive the entire movable tube 7005 to move out from one end of the inner tube 7001. In the process of the inner tube 7001 moving out, the length of the exposed through groove 7007 will also be longer, thereby increasing the flow rate of the coolant in the entire regulating channel 4008, enhancing the heat dissipation performance of the entire aluminum plate 1, and realizing the self-regulation of the heat dissipation of the aluminum plate 1. The width of the entire through groove 7007 gradually decreases in the direction away from the outer ring plate 7002, thereby further increasing the flow rate of the coolant in the regulating channel 4008.

At this time, the spring 8004 in a compressed state on one side of the positioning plate 8002 will immediately reset, thereby applying a reverse thrust to the movable tube 7005, so that the movable tube 7005 can quickly reset to reduce the flow rate of the coolant inside the adjustment channel 4008. The entire adjustment process can be achieved by adding or subtracting the coolant flow rate inside the aluminum plate 1, meeting people's usage needs.
