[0061] Example 1

[0062] This application provides a heat sink that allows all the cool air blown out by the fan to pass through the heat sink core assembly 1, thereby improving the heat sink's heat dissipation efficiency. A detailed description of this heat sink is provided in conjunction with... Figures 1-17 As shown, the explanation is as follows.

[0063] The heat sink provided in this application includes a core assembly 1, a main plate 2, and a support plate 5; wherein the core assembly 1 is connected to the main plate 2 at both ends along a first direction 7; the support plate 5 is respectively disposed on the end face of the core assembly 1 along a second direction 9 and its two ends along the first direction 7 are respectively connected to the main plate 2. Specifically, in conjunction with Figure 1 As shown, and with Figure 1 Taking the placement angle as an example, the first direction 7 refers to the vertical direction, the second direction 9 refers to the left-right direction, and the third direction 12 (described below) refers to the inward-outward direction. The core assembly 1 has main plates 2 at its upper and lower ends, and support plates 5 at its left and right ends. Furthermore, the core assembly 1 includes cooling pipes and heat sinks. Multiple cooling pipes are arranged at intervals along the second direction 9, and heat sinks are disposed within adjacent cooling pipes. It is worth noting that the cooling pipes and heat sinks are not labeled in the figures; their structure is the basic structure of a heat sink and is understandable to those skilled in the art.

[0064] The radiator of this application also includes a first seal 10, a wind shield 3, and a second seal 11.

[0065] Specifically, the core assembly 1 has an air intake surface 14 and an air outlet surface along the third direction 12; the wind shield 3 is fastened to the air intake surface 14 of the core assembly 1, and the edges of the wind shield 3 along the first direction 7 are respectively connected to the main plate 2, and a first sealing element 10 is provided between the wind shield 3 and the main plate 2; preferably, the first sealing element 10 is a sponge strip, which seals the edges of the main plate 2 and the wind shield 3 along the first direction 7 to prevent air from leaking out through the gap between the main plate 2 and the edges of the wind shield 3 along the first direction 7. In other words, it can collect the air that leaks out from the gap in the prior art and use it all for heat dissipation of the radiator, thereby improving the heat dissipation efficiency of the radiator to a certain extent.

[0066] Specifically, in combination Figure 8 and Figure 9 As shown, since the size of the support plate 5 in the third direction 12 is smaller than the size of the main plate 2 in the third direction 12, a gap will also be formed between the support plate 5 and the core assembly 1 when the support plate 5 is connected to the main plate 2. This application provides a second sealing member 11 on the side of the support plate 5 away from the core assembly 1, which can seal the gap formed between the support plate 5 and the core assembly 1. Preferably, the second sealing member 11 is a sponge strip. The sponge strip is used to seal the gap formed between the support plate 5 and the core assembly 1 to prevent air from leaking out through the gap formed between the support plate 5 and the core assembly 1. In other words, the air that leaks out from the gap in the prior art can be collected and used entirely for heat dissipation of the radiator, thereby improving the heat dissipation efficiency of the radiator to a certain extent.

[0067] Furthermore, the second seal 11 extends along the first direction 7 and connects with the first seal 10, so that the first seal 10, the second seal 11 and the wind shield 3 surround a sealing cavity on the air intake surface 14; that is, a sealing cavity is formed between the air intake surface 14 of the core assembly 1 and the fan, so that the air blown out by the fan can be fully applied to the core assembly 1 and fully dissipate heat from the heat sink, thus improving the heat dissipation efficiency of the heat sink to a certain extent.

[0068] In this embodiment, further, combined with Figure 2 and Figure 3 As shown, the radiator also includes a side plate 4.

[0069] Specifically, the side plate 4 is located on the side of the second seal 11 away from the core assembly 1, and wraps the second seal 11 around the support plate 5.

[0070] Specifically, the side plate 4 is fixedly connected to the edge of the wind shield 3 along the third direction 12 and near the edge of the wind shield 3 along the second direction 9.

[0071] Preferably, the edge of the side plate 4 along the third direction 12 and close to the edge of the wind shield 3 along the second direction 9 is connected to the edge of the wind shield 3 by bolts.

[0072] In this embodiment, further, combined with Figure 10 and Figure 11 As shown, the wind shield 3 also includes a first fixing edge 16.

[0073] Specifically, the first fixing edge 16 is set at a preset angle on the sealing edge 36 of the wind shield 3 along the first direction 7, and the first fixing edge 16 extends toward the main piece 2, so that the first fixing edge 16 and the sealing edge 36 of the wind shield 3 along the first direction 7 form a bent wrapping part 17; the bent wrapping part 17 can wrap the first sealing member 10 around the main piece 2.

[0074] Furthermore, the preset angle is 90 degrees, meaning the first fixing edge 16 and the sealing edge 36 are perpendicularly connected to form a bent wrapping portion 17. The first fixing edge in this bent wrapping portion 17 can fix the side wall of the first seal 10 away from the core assembly 1, and the sealing edge 36 in this bent wrapping portion 17 can fix the side wall of the first seal 10 away from the main plate 2. In this way, even if all the air blown by the fan acts on the core assembly 1 (when all the air acts on the core assembly 1, the wind force will be relatively large), the first seal 10 will not fall off the main plate 2 due to excessive wind force.

[0075] In this embodiment, further, combined with Figure 10 and Figure 11 As shown, the wind shield 3 has a groove 19 along the edge of the first direction 7 and on the side near the side plate 4.

[0076] Combination Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 12 As shown, the radiator also includes an auxiliary mounting plate 20 disposed in the slot 19. The auxiliary mounting plate 20 includes a first main body 21, a second main body 22, and a third main body 23. The first main body 21 and the second main body 22 are connected at a preset angle. Preferably, the first main body 21 and the second main body 22 are connected perpendicularly. The first main body 21 extends along the second direction 9 and is connected to the first fixed edge 16. The second main body 22 extends along the second direction 9 and is connected to the edge of the wind shield 3 along the first direction 7. The third main body 23 is connected to the second main body 22 at a preset angle and is connected to the wind shield 3 through a connector.

[0077] Furthermore, the side plate 4 extends along both ends of the first direction 7 toward the main plate 2 with a fastening plate 18; the fastening plate 18 fastens at least part of the second main body 22.

[0078] In summary, a groove 19 is provided on the edge of the wind shield 3 along the first direction 7 and on the side near the side plate 4. The setting of this groove 19 makes it possible to install the fastening plate 18. However, since the groove 19 is provided on the wind shield 3, the first sealing member 10 corresponding to the groove 19 is not fixed by a fastener 30. In order to solve this problem, this application provides an auxiliary fastening plate 20 in this embodiment. The auxiliary fastening plate 20 is used to fix the first sealing member 10 corresponding to the groove 19. Furthermore, the first body 21 fixes the end of the sealing member away from the core assembly 1, and the second body 22 fixes the end of the sealing member away from the main plate 2.

[0079] In this embodiment, further, combined with Figure 11 and Figure 12 As shown, the connector includes a connecting pin 24, and the wind shield 3 has a connecting hole 25 at the position corresponding to the connecting pin 24; the connecting pin 24 and the connecting hole 25 are interference-fitted to fix the auxiliary buckle plate 20 and the wind shield 3 together.

[0080] Specifically, the connecting pin 24 is located on the side of the third body 23 facing the wind shield, and the wind shield 3 has a connecting hole 25 at the position corresponding to the connecting pin 24. By inserting the connecting pin 24 into the connecting hole 25, the auxiliary buckle plate 20 and the wind shield 3 can be fixed together.

[0081] In this embodiment, further, combined with Figure 1 , Figure 13 , Figure 14 , Figure 17 As shown, the radiator also includes an upper water chamber 32 and a lower water chamber 33, which are respectively attached to both ends of the main plate 2 along the first direction 7, and the upper water chamber 32 and the lower water chamber 33 respectively form water-containing cavities on the main plate 2.

[0082] Specifically, the cooling pipes of the water-containing cavity are connected.

[0083] Furthermore, the upper water chamber 32 has a water inlet hole 34; the lower water chamber 33 has a water outlet hole 35.

[0084] In this embodiment, further, combined with Figures 14-16 As shown, the radiator also includes a sign 26; the water chamber 32 has a mounting position 27 on the air intake side 14; the sign 26 is located at the mounting position 27.

[0085] Specifically, the side wall of the water chamber 32 is provided with ribs, and the installation position 27 is actually an installation groove formed on the water chamber 32; that is, an installation groove is cut out on the water chamber 32 by cutting (cutting the ribs).

[0086] More specifically, the radiator also includes a cover plate 28; a connecting seat 29 is provided on the mounting position 27, and a fastener 30 is provided on the side of the cover plate 28 facing the main plate 2 and corresponding to the position of the connecting seat 29.

[0087] Furthermore, the cover plate 28 covers the side of the sign 26 away from the main piece 2, and the cover plate 28 has a through hole 31 that can expose the sign 26; the sign 26 can be fixed to the water chamber 32 by the fastener 30.

[0088] Furthermore, the sign 26 is made of extremely thin aluminum, making it very lightweight and unlikely to damage the water chamber. Additionally, the mounting groove is cut from the water chamber, and the connecting seat 29 does not protrude from it, thus allowing the sign 26 to be concealed within the water chamber. This design facilitates production and transportation. The cover plate 28 is a different color from the sign 26, making it easy to identify the position of the sign 26. The fastener 30 is interference-fitted with the through hole 31, and the fastener 30 is a fixing screw.

[0089] Preferably, the label 26 displays the manufacturer's markings, supplier code, production date, serial number, verification code, part number, reserved code space, QR code information, etc.

[0090] Example 2

[0091] In this embodiment, further, combined with Figures 2-5 As shown, the side plate 4 has fastening plates 18 extending from both ends of the side plate 4 along the first direction 7 toward the main plate 2, and the fastening plates 18 are fastened to the edge of the wind shield 3 along the first direction 7.

[0092] Specifically, combined Figure 3 As shown, since the fastening plate 18 extends along the second direction 9 and is located at both ends of the side plate 4 along the first direction 7, the fastening plate 18 can, to a certain extent, stably fix the side plate 4 to the main plate 2 and prevent the side plate 4 from falling off the main plate 2; and since the side plate 4 facing the core assembly 1 is fixed with the second sealing element 11, the fastening plate 18 can stably fix the second sealing element 11 to the support plate 5 and the windproof cover.

[0093] Example 3

[0094] This application also provides an automobile that includes the aforementioned radiator. Therefore, it possesses all the beneficial effects of the aforementioned radiator, which will not be specifically elaborated upon here.

[0095] Combination Figure 1 As shown, an intercooler 8 is installed on the air outlet surface of the core assembly.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
