DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 4A heat dissipation housing 100 , a radiator 1000 and a vehicle according to an embodiment of the present invention are described.

[0030] like Figure 1-Figure 4 As shown, the heat dissipation housing 100 according to the embodiment of the utility model includes: a shell 10 and a heat dissipation part 20, the shell 10 has a first shell 11 and a second shell 12, and a plurality of heat dissipation zones are formed on a side of the first shell 11 away from the second shell 12; the heat dissipation part 20 is arranged in the plurality of heat dissipation zones, and the extension direction of the heat dissipation part 20 in each heat dissipation zone is different, so as to increase the air intake amount by taking in air from multiple directions.

[0031] Specifically, the first shell 11 and the second shell 12 are arranged opposite to each other, and a side of the first shell 11 away from the second shell 12 is divided into different heat dissipation zones, each heat dissipation zone corresponds to a side of the first shell 11, and a heat dissipation portion 20 is arranged on the first shell 11, one end of the heat dissipation portion 20 is connected to the side of the first shell 11 away from the second shell 12, and the other end of the heat dissipation portion 20 extends in a direction away from the second shell 12. A heat dissipation portion 20 is arranged in each heat dissipation zone, but the extension direction of the heat dissipation portion 20 in each heat dissipation zone is different. The present application sets a plurality of heat dissipation zones and sets heat dissipation portions 20 with different extension directions in the plurality of heat dissipation zones. Compared with the heat dissipation method in the prior art, the heat dissipation portion 20 is divided into zones and turned, so that airflow can enter the heat dissipation portion 20 from multiple different directions, and the air intake is increased compared with the prior art, and the length of the heat dissipation portion 20 is shortened, so as to avoid the airflow flowing in the heat dissipation portion 20 from being too long, thereby improving the exchange efficiency of the airflow and effectively improving the heat dissipation efficiency.

[0032] According to the heat dissipation shell 100 of the embodiment of the utility model, by arranging multiple heat dissipation zones on the shell body 10 and arranging heat dissipation parts 20 with different extension directions in the multiple heat dissipation zones, the partitioning and steering of the heat dissipation part 20 can be realized. Compared with the prior art, the present application increases the entry direction of the airflow, and enables the airflow to enter the heat dissipation part 20 from all sides of the first shell 11, thereby avoiding the situation where the airflow is blocked and the side airflow is wasted, increasing the air intake volume, and shortening the length of the heat dissipation part 20 by partitioning the heat dissipation part 20, shortening the distance that the airflow flows between the heat dissipation parts 20, improving the exchange efficiency of the airflow, and thus improving the heat dissipation effect of the heat dissipation shell 100.

[0033] like Figure 1-Figure 4 As shown, in some embodiments, multiple heat dissipation zones extend from multiple sides of the first shell 11 toward the center of the first shell 11 to form a first heat dissipation zone, a second heat dissipation zone, a third heat dissipation zone and a fourth heat dissipation zone; the first heat dissipation zone is arranged opposite to the second heat dissipation zone, and the third heat dissipation zone is arranged opposite to the fourth heat dissipation zone.

[0034] It should be noted that each heat dissipation zone corresponds to a side of the first shell 11, and the first shell 11 has a first side 111, a second side 112, a third side 113 and a fourth side 114, wherein the first side 111 is opposite to the second side 112, and the third side 113 is opposite to the fourth side 114. The first heat dissipation zone extends from the first side 111 toward the center of the first shell 11, and the second heat dissipation zone extends from the second side 112 toward the center of the first shell 11, and the first heat dissipation zone is opposite to the second heat dissipation zone; the third heat dissipation zone extends from the third side 113 toward the center of the first shell 11, and the fourth heat dissipation zone extends from the fourth side 114 toward the center of the first shell 11, and the third heat dissipation zone is opposite to the fourth heat dissipation zone.

[0035] In this way, the side of the first shell 11 away from the second shell 12 can be evenly divided to improve the uniformity of heat dissipation, and by dividing the first shell 11 into different zones, the heat dissipation portion 20 can be divided into different zones.

[0036] like Figure 1-Figure 4 As shown, specifically, the heat dissipation portion 20 has a plurality of heat dissipation fins 21, and the heat dissipation fins 21 include a first heat dissipation fin 211, a second heat dissipation fin 212, a third heat dissipation fin 213 and a fourth heat dissipation fin 214 having different extension directions; the first heat dissipation fin 211 is arranged in the first heat dissipation zone, and the plurality of first heat dissipation fins 211 extend from the first side 111 of the first shell 11 toward the center of the first shell 11; the second heat dissipation fin 212 is arranged in the second heat dissipation zone, and the plurality of second heat dissipation fins 212 extend from the second side 112 of the first shell 11 toward the center of the first shell 11; the third heat dissipation fin 213 is arranged in the third heat dissipation zone, and the plurality of third heat dissipation fins 213 extend from the third side 113 of the first shell 11 toward the center of the first shell 11; the fourth heat dissipation fin 214 is arranged in the fourth heat dissipation zone, and the plurality of fourth heat dissipation fins 214 extend from the fourth side 114 of the first shell 11 toward the center of the first shell 11.

[0037] Specifically, the heat dissipation portion 20 is composed of a plurality of heat dissipation fins 21 arranged at intervals, and the plurality of heat dissipation fins 21 are divided into a first heat dissipation fin 211 arranged in a first heat dissipation zone, a second heat dissipation fin 212 arranged in a second heat dissipation zone, a third heat dissipation fin 213 arranged in a third heat dissipation zone, and a fourth heat dissipation fin 214 arranged in a fourth heat dissipation zone. The heat dissipation fins 21 in different heat dissipation zones have different setting directions, and the extension direction of the heat dissipation fins 21 is the same as the extension direction of the heat dissipation zone.

[0038] It should be noted that the first heat dissipation fin 211, the second heat dissipation fin 212, the third heat dissipation fin 213 and the fourth heat dissipation fin 214 all extend from the side of the first shell 11 toward the interior of the first shell 11, and the heat dissipation fins 21 are arranged in a tapered manner from the side of the first shell 11 to the interior of the first shell 11. The multiple heat dissipation fins 21 in each heat dissipation zone can be arranged in a triangular structure, a trapezoidal structure, etc., and are spaced apart between adjacent heat dissipation zones, and the heat dissipation fins 21 at the edges of adjacent heat dissipation zones are also spaced apart.

[0039] In this way, setting the heat dissipation part 20 with heat dissipation fins 21 with different extension directions can enable airflow to enter from different directions to increase the airflow volume, and the heat dissipation fins 21 with multiple extension directions are laid together on the side of the first shell 11 away from the second shell 12, which can shorten the flow path of the airflow and make the incoming airflow flow out quickly, thereby improving the heat exchange efficiency.

[0040] like Figure 2 As shown, in some embodiments, the length of multiple first heat dissipation fins 211 gradually decreases from the center of the first side 111 toward its two ends; the length of multiple second heat dissipation fins 212 gradually decreases from the center of the second side 112 toward its two ends; the length of multiple third heat dissipation fins 213 gradually decreases from the center of the third side 113 toward its two ends; the length of multiple fourth heat dissipation fins 214 gradually decreases from the center of the fourth side 114 toward its two ends.

[0041] It should be noted that the projection contours of the multiple heat dissipation zones gradually shrink from the side of the first shell 11 toward the center of the first shell 11. Exemplarily, the multiple heat dissipation zones can be constructed as triangular areas, and the heat dissipation fins 21 in the multiple heat dissipation zones all extend from the side of the first shell 11 adjacent to each other toward the interior of the first shell 11. The heat dissipation fin 21 located at the center position in each heat dissipation zone, that is, the heat dissipation fin 21 corresponding to the center of the side has the longest length, and the multiple heat dissipation fins 21 corresponding to the longest heat dissipation fin 21 on both sides of the longest heat dissipation fin 21 gradually shorten in the direction toward the side end.

[0042] This arrangement makes it easy to set up heat dissipation fins 21 with different air intake directions to achieve the purpose of air intake in four directions. The lengths of the multiple heat dissipation fins 21 in each heat dissipation area are different. The airflow at the heat dissipation fins 21 with shorter lengths can flow out more quickly, which can evenly dissipate heat in each area and improve the heat dissipation effect.

[0043] like Figure 4 As shown, in other embodiments, each heat dissipation zone has a middle section and edge sections located on both sides of the middle section, and the length of the plurality of heat dissipation fins 21 located in the middle section is greater than the length of the plurality of heat dissipation fins 21 located in the edge sections.

[0044] For example, Figure 4As shown, the lengths of the first heat dissipation fins 211 arranged in the middle section of the first heat dissipation zone are approximately equal, and the lengths of the multiple first heat dissipation fins 211 from the edge of the middle section to the end of the first side 111 are gradually shortened; the lengths of the second heat dissipation fins 212 arranged in the middle section of the second heat dissipation zone are approximately equal, and the lengths of the multiple second heat dissipation fins 212 from the edge of the middle section to the end of the second side 112 are gradually shortened; the lengths of the third heat dissipation fins 213 arranged in the middle section of the third heat dissipation zone are approximately equal, and the lengths of the multiple third heat dissipation fins 213 from the edge of the middle section to the end of the third side 113 are gradually shortened; the lengths of the fourth heat dissipation fins 214 arranged in the middle section of the fourth heat dissipation zone are approximately equal, and the lengths of the multiple fourth heat dissipation fins 214 from the edge of the middle section to the end of the fourth side 114 are gradually shortened. Among them, the length of the middle section of the heat dissipation fins 21 in the third heat dissipation zone and the fourth heat dissipation zone is greater than the length of the middle section of the heat dissipation fins 21 in the first heat dissipation zone and the second heat dissipation zone; or, the length of the middle section of the heat dissipation fins 21 in the first heat dissipation zone and the second heat dissipation zone is greater than the length of the middle section of the heat dissipation fins 21 in the third heat dissipation zone and the fourth heat dissipation zone.

[0045] In addition to the above embodiments, there are many other embodiments, for example, Figure 3 As shown, the lengths of the plurality of first heat dissipation fins 211 gradually decrease from the center of the first side 111 toward its two ends; the lengths of the plurality of second heat dissipation fins 212 gradually decrease from the center of the second side 112 toward its two ends; the lengths of the third heat dissipation fins 213 disposed in the middle section of the third heat dissipation zone are substantially equal, and the lengths of the plurality of third heat dissipation fins 213 gradually decrease from the edge of the middle section to the end of the third side 113; the lengths of the fourth heat dissipation fins 214 disposed in the middle section of the fourth heat dissipation zone are substantially equal, and the lengths of the plurality of fourth heat dissipation fins 214 gradually decrease from the edge of the middle section to the end of the fourth side 114.

[0046] Alternatively, the lengths of the plurality of third heat dissipation fins 213 gradually decrease from the center of the third side 113 toward its two ends; the lengths of the plurality of fourth heat dissipation fins 214 gradually decrease from the center of the fourth side 114 toward its two ends; the lengths of the first heat dissipation fins 211 disposed in the middle section of the first heat dissipation area are substantially equal, and the lengths of the plurality of first heat dissipation fins 211 from the edge of the middle section to the end of the first side 111 gradually decrease; the lengths of the second heat dissipation fins 212 disposed in the middle section of the second heat dissipation area are substantially equal, and the lengths of the plurality of second heat dissipation fins 212 from the edge of the middle section to the end of the second side 112 gradually decrease.

[0047] It should be noted that, in the first two embodiments, multiple first heat dissipation fins 211 and multiple second heat dissipation fins 212 form a trapezoidal structure, and multiple third heat dissipation fins 213 and multiple fourth heat dissipation fins 214 form a combination of a trapezoidal structure and a rectangular structure, wherein the rectangular structure corresponds to the middle section; or, multiple third heat dissipation fins 213 and multiple fourth heat dissipation fins 214 form a trapezoidal structure, and multiple first heat dissipation fins 211 and multiple second heat dissipation fins 212 form a combination of a trapezoidal structure and a rectangular structure, wherein the rectangular structure corresponds to the middle section; in the latter two embodiments, multiple first heat dissipation fins 211 and multiple second heat dissipation fins 212 form a triangular structure, and multiple third heat dissipation fins 213 and multiple fourth heat dissipation fins 214 form a trapezoidal structure; or, multiple third heat dissipation fins 213 and multiple fourth heat dissipation fins 214 form a triangular structure, and multiple first heat dissipation fins 211 and multiple second heat dissipation fins 212 form a trapezoidal structure.

[0048] In this way, as many cooling fins 21 as possible can be arranged on the first shell 11, so that the cooling fins 21 cover as much area of ​​the first shell 11 as possible on the side away from the second shell 12, and can let in air from four directions, and can ensure that the air intake amounts in the four directions are roughly the same, so that the setting form of the cooling fins 21 is diversified, and can be specifically set according to needs and convenience of setting, which can effectively improve the heat dissipation effect.

[0049] like Figure 1-Figure 4 As shown, in some embodiments, a plurality of heat-exchanging fins 21 are arranged at intervals in each heat-exchanging zone, and a heat-exchanging air duct 22 is formed between adjacent heat-exchanging fins 21. The heat-exchanging air ducts 22 in the plurality of heat-exchanging zones are used to provide heat-exchanging airflows in a plurality of air inlet directions to the first shell 11. The heat-exchanging air duct 22 has an air inlet 221 and an air outlet 222. The air inlet 221 of the heat-exchanging air duct 22 in each heat-exchanging zone is respectively oriented toward the side of the first shell 11 body 10 adjacent thereto, and the air outlet 222 of the heat-exchanging air duct 22 in each heat-exchanging zone is at an end of the heat-exchanging fin 21 away from the first shell 11.

[0050] Specifically, adjacent heat-exchange air ducts 21 are formed with heat-exchange air ducts 22, the air inlet 221 of the heat-exchange air duct 22 of the first heat-exchange zone is located at the first side 111, the air inlet 221 of the heat-exchange air duct 22 of the second heat-exchange zone is located at the second side 112, the air inlet 221 of the heat-exchange air duct 22 of the third heat-exchange zone is located at the third side 113, and the air inlet 221 of the heat-exchange air duct 22 of the fourth heat-exchange zone is located at the fourth side 114, so that air can be respectively taken in from all around the first shell 11, the outlets of the heat-exchange air duct 22 in each heat-exchange zone are consistent, and the airflow flows out from the end of the heat-exchange fins 21 away from the second shell 12. This arrangement enables the airflow around the first shell 11 to enter the heat-exchange air duct 22, increases the airflow for heat dissipation of the first shell 11, improves the exchange efficiency of the airflow, and improves the heat dissipation effect.

[0051] like Figure 1 As shown, the heat sink 1000 according to the embodiment of the utility model comprises: a chip 200 and a heat dissipation housing 100 of any one of the above embodiments, the first housing 11 having a receiving space, and the chip 200 is placed in the receiving space. The heat sink 1000 also comprises: a mainboard 300, the mainboard 300 is arranged in the receiving space, the chip 200 is mounted on a side of the mainboard 300 close to the first housing 11, and the chip 200 is connected to the first housing 11 through a heat conducting member 400.

[0052] Specifically, the chip 200 can be fixed on the mainboard 300 by reflow soldering, and of course it can also be fixed by other methods. After fixing the chip 200, a heat conductive member 400 is set on the chip 200, wherein the heat conductive member 400 can be a heat conductive gel, which can be applied on the chip 200. Of course, the heat conductive member 400 can also be other materials with heat conductive function. After the heat conductive member 400 is set, the mainboard 300 is installed in the accommodation space, and the second shell 12 is fixed to the first shell 11 by the fastener 500. The heat dissipation housing 100 and the chip 200 are connected by the heat conductive member 400. When the chip 200 is working, a large amount of heat will be generated. The heat is transferred to the heat dissipation housing 100 through the heat conductive member 400, and finally the heat is dissipated into the air through the heat dissipation housing 100, thereby ensuring that the chip 200 will not be damaged due to excessive temperature.

[0053] This arrangement can effectively transfer the heat generated by the mainboard 300 and the chip 200 to the heat dissipation housing 100 and quickly conduct the heat through the heat dissipation part 20 arranged in the heat dissipation housing 100, thereby improving the heat dissipation effect of the radiator 1000 and achieving rapid heat dissipation.

[0054] The vehicle according to the embodiment of the utility model comprises the radiator 1000 of any one of the above embodiments. The vehicle of the present application can improve the heat dissipation effect and achieve the purpose of rapid heat dissipation by adopting the above radiator 1000, which is beneficial to the safety of the vehicle.
