Description

Technical Field

[0001] This application relates to the field of equipment technology for automobiles, and more particularly to radiators and automobiles. Background Technology

[0002] As vehicle emission standards become increasingly stringent or vehicle load requirements increase, the need for engine radiators to remove more and more heat has increased. As a result, current radiators have become taller and thicker, or wider and taller.

[0003] When firing the core assembly of the radiator, it is necessary to divide it into two parts due to its large size, and then fire them separately in the furnace.

[0004] However, the following problems often occur after the two parts are baked: (1) the edge of the core assembly will be deformed due to baking; (2) the two parts cannot be assembled and welded to form the whole core assembly after baking.

[0005] Therefore, there is an urgent need for a radiator and a car that can, to some extent, solve the technical problems existing in the current technology. Utility Model Content

[0014] The snap-fit ​​plate and the supporting flange are arranged at intervals along the third direction;

[0015] The snap-fit ​​plate is positioned corresponding to the limiting groove and the two are the same size, so that the snap-fit ​​plate can snap into the limiting groove;

[0016] The snap-fit ​​plate protrudes from the support flange in the first direction, and the snap-fit ​​plate and the support flange are at a 90° angle. The support flange extends toward the interior of the sub-core, such that when the snap-fit ​​plate is snapped into the limiting groove, the support flange supports the side wall of the main piece toward the sub-core.

[0017] In the above technical solution, the radiator further includes a housing;

[0018] The housing is fastened to the main plate and forms a water chamber;

[0023] The reinforcing plate has a reinforcing part and a side clamping part; the side clamping parts are respectively disposed at both ends of the reinforcing plate along the first direction, and are respectively inserted into the flow port of the adjacent cooling pipe.

[0024] In the above technical solution, the reinforcing plate further includes reinforcing pieces and clamping pieces;

[0025] The clips are provided in multiple sets;

[0026] Multiple sets of the clamping pieces are arranged at intervals along the third direction on the reinforcing piece.

[0028] The support plates are respectively disposed at the ends of the core assembly along the first direction;

[0029] The support plate extends along the second direction and its ends along the second direction are respectively connected to the main plate.

[0030] In the above technical solution, the main piece is further bent with a snap-fit ​​ear at one end along the first direction and away from the partition.

[0031] The support plate has a snap-fit ​​groove corresponding to the snap-fit ​​ear, and the snap-fit ​​ear can snap into the snap-fit ​​groove, so that the support plate and the main piece are fixed together.

[0032] In the above technical solution, the support plate further includes a support main board and a support connecting plate;

[0033] The support connecting plate is disposed at both ends of the support main board along the second direction and is bent and connected at the side wall of the main piece facing the sub-core, so that a receiving part capable of supporting the side wall of the main piece facing the sub-core is formed between the support main board and the support connecting plate.

[0034] This application also provides an automobile that includes the aforementioned radiator.

The snap-fit ​​portion can snap onto the limiting portion, and when the snap-fit ​​portion snaps onto the limiting portion, the support portion can support the side wall of the main piece facing the sub-core.

[0040] In summary, this application utilizes a partition to seal the exposed heat sink fins caused by the separated core assembly, protecting them and isolating them from the external environment. This prevents deformation of the heat sink fins during firing, thus ensuring their integrity. Furthermore, the snap-fit ​​part engages with the limiting part, and the supporting part supports the side wall of the main plate facing the sub-core, enabling the first and second sub-cores to be assembled into a core assembly.

[0071] Example 1

[0072] This application provides a heat sink structure that ensures the two-part core assembly 1 remains intact and undeformed after firing, and also ensures that the two-part core assembly 1 can still form a complete whole after firing. The specific structure of the heat sink is described below in conjunction with... Figures 1-18 Detailed description.

[0073] Combination Figure 1 As shown, the heat sink includes a core assembly 1, a main plate 2, and a partition 3.

[0074] Specifically, the core assembly 1 is divided into multiple sub-cores along the first direction 4, according to... Figure 1Taking the arrangement of the components as an example, the first direction 4 refers to the left and right direction, and the second direction 7 (described below) refers to the vertical direction. In addition, in this embodiment, the core assembly 1 is divided into two sub-cores for detailed explanation. The two sub-cores are the first sub-core 5 and the second sub-core 6.

[0075] Furthermore, combined Figure 1 As shown, the radiator also includes a housing 20; the housing 20 is fastened to the main plate 2 and forms a water chamber; combined with Figure 8 and Figure 9 As shown, the first sub-core 5 (second sub-core 6) includes a plurality of cooling pipes 21 arranged at intervals along the first direction 4, and heat sinks 22 are provided between adjacent cooling pipes 21; combined with Figure 15 As shown, the main plate 2 has a mounting hole 23 at the position corresponding to the cooling pipe 21, and the cooling pipe 21 passes through the mounting hole 23 and is connected to the water chamber.

[0076] Specifically, adjacent sidewalls of adjacent sub-cores are each provided with a partition 3 extending along the second direction 7, i.e., combined with Figure 1 As shown, partitions 3 are provided on the sidewall of the first sub-core 5 facing the second sub-core 6 and on the sidewall of the second sub-core 6 facing the first sub-core 5. The partitions 3 can seal the heat sink 22 exposed by the separated core assembly 1, and protect the exposed heat sink 22, so that it is isolated from the external environment. In this way, the heat sink 22 will not deform during firing, thus ensuring the integrity of the heat sink 22.

[0077] Specifically, the main sheet 2 is respectively disposed at both ends of the sub-core along the second direction 7, and the end of the main sheet 2 along the first direction 4 and near the partition 3 is provided with a limiting part 9; the two ends of the partition 3 along the second direction 7 are provided with a snap-fit ​​part 10 extending along the second direction 7 and a supporting part 11 at a preset angle to the snap-fit ​​part 10. The snap-fit ​​part 10 can snap onto the limiting part 9, and when the snap-fit ​​part 10 snaps onto the limiting part 9, the supporting part 11 can support the side wall of the main sheet 2 facing the sub-core. Specifically, after the first sub-core 5 and the second sub-core 6 are fired, the snap-fit ​​part 10 of the partition 3 is first snapped onto the limiting part 9, and the supporting part 11 is supported on the side wall of the main sheet 2 facing the sub-core; then the gap between the partition 3 and the main sheet 2 is welded together by welding, so that the first sub-core 5 and the second sub-core 6 are assembled into the core assembly 1.

[0078] In summary, this application utilizes the partition 3 to seal the exposed heat sink 22 caused by the separation of the core assembly 1, protecting the exposed heat sink 22 and isolating it from the external environment. This prevents deformation of the heat sink 22 during firing, thus ensuring its integrity. Furthermore, the snap-fit ​​part 10 engages with the limiting part 9, and the supporting part 11 supports the side wall of the main plate 2 facing the sub-core, enabling the first sub-core 5 and the second sub-core 6 to be assembled into the core assembly 1.

[0079] In this embodiment, further, combined with Figure 6 , Figure 8 as well as Figure 15 As shown, the main piece 2 has a first flange 14, a second flange 15 and a third flange 16 formed sequentially along the third direction 12 along the first direction 4 and the end near the partition 3;

[0081] Specifically, in combination Figure 15 As shown, the first flange 14 and the third flange 16 both protrude from the second flange 15 in the first direction 4, so that the first flange 14, the second flange 15 and the third flange 16 are surrounded by a limiting groove 17 that can serve as a limiting part 9.

[0082] In this embodiment, further, combined with Figure 10 As shown, the snap-fit ​​part 10 is a snap-fit ​​plate 18, and the support part 11 is a support flange 19; the snap-fit ​​plate 18 and the support flange 19 are arranged at intervals along the third direction 12.

[0083] Specifically, the snap-fit ​​plate 18 and the limiting groove 17 are positioned correspondingly and have the same dimensions, and are combined Figure 15 As shown, the limiting groove 17 is elongated, combined with... Figure 10 As shown, the snap-fit ​​plate 18 is long and narrow. The fact that the two have the same size means that the length and width of the limiting groove 17 and the snap-fit ​​plate 18 are the same. In this way, the snap-fit ​​plate 18 can be snapped into the limiting groove 17. That is, after the first sub-core 5 and the second sub-core 6 are fired, the snap-fit ​​plate 18 can be snapped into the limiting groove 17 on the main plate 2, thereby fixing the partition plate 3 on the main plate 2.

[0084] Specifically, in combination Figure 10 As shown, the snap-fit ​​plate 18 protrudes from the support flange 19 in the first direction 4, the snap-fit ​​plate 18 and the support flange 19 are at a 90° angle, and the support flange 19 extends towards the interior of the sub-core, thus connecting... Figure 5 As shown, when the snap-fit ​​plate 18 is snapped into the limiting groove 17, the supporting flange 19 supports the side wall of the main piece 2 facing the sub-core.

[0085] In this embodiment, combined with Figure 9 As shown, the radiator also includes a reinforcing plate 24; the reinforcing plate 24 is disposed at the end of the cooling pipe 21 inside the sub-core along the first direction 4.

[0086] Specifically, in combination Figure 13 As shown, the reinforcing plate 24 has a reinforcing part 25 and a side clamping part 26; the side clamping parts 26 are respectively disposed at both ends of the reinforcing plate 24 along the first direction 4, and can be respectively inserted into the flow port 27 of the adjacent cooling pipe 21.

[0087] Furthermore, the reinforcing plate 24 includes reinforcing pieces 28 and clamping pieces 29; multiple sets of clamping pieces 29 are provided, and each set of clamping pieces 29 refers to one clamping piece 29 located at each end of the reinforcing piece 28 along the first direction 4. Figure 13 As shown, preferably, the clips 29 are provided in two sets, and the two sets of clips 29 are arranged at intervals along the third direction 12 on the reinforcing plate 28.

[0088] In this embodiment, combined with Figure 2 , Figure 3 As shown, the radiator also includes a support plate 30.

[0089] Specifically, the support plates 30 are respectively disposed at the ends of the core assembly 1 along the first direction 4; the support plates 30 extend along the second direction 7 and are respectively connected to the main piece 2 at their ends along the second direction 7.

[0090] Specifically, in combination Figure 14 As shown, the main piece 2 is bent along the first direction 4 and the end facing away from the partition 3 has a snap-fit ​​ear 31; the support plate 30 has a snap-fit ​​groove at the position corresponding to the snap-fit ​​ear 31, and the snap-fit ​​ear 31 can snap into the snap-fit ​​groove, so that the support plate 30 and the main piece 2 are fixed together.

[0091] Specifically, the support plate 30 includes a support main plate 32 and a support connecting plate 33; the support connecting plate 33 is disposed at both ends of the support main plate 32 along the second direction 7 and is bent and connected at the side wall of the main piece 2 facing the sub-core, so that a receiving part 34 is formed between the support main plate 32 and the support connecting plate 33, which can support the side wall of the main piece 2 facing the sub-core.

[0092] Furthermore, combined Figure 16 and Figure 17 As shown, the support plate 30 has a snap-fit ​​groove at the position corresponding to the snap-fit ​​ear 31. The snap-fit ​​groove includes a first L-shaped groove 36, a groove 38 and a second L-shaped groove 37 connected in sequence. The first L-shaped groove 36 and the second L-shaped groove 37 are symmetrically arranged about the axis of the support plate 30. The first L-shaped groove 36 and the second L-shaped groove 37 are respectively corresponding to the snap-fit ​​ear 31.

[0093] Furthermore, the main piece 2 has a protrusion formed along the first direction 4 and at one end away from the partition plate 3 and in the middle of the two snap-fit ​​ears 31, and the groove 38 corresponds to the position of the protrusion, so that the support plate 30 is firmly fixed to the main piece 2.
