Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, and in particular to an automotive radiator core. Background Technology

[0002] The radiator core is the core of the radiator, which is usually composed of a series of fins and cooling pipes. The fins are mostly made of aluminum or copper, which have good thermal conductivity. The cooling pipes are responsible for guiding the engine coolant to the fins and reducing the coolant temperature through heat exchange with the outside air. The cooling pipes mostly have a flat circular cross-section to reduce air resistance and increase the heat transfer area.

[0003] The heat sinks in existing automotive radiator cores mostly adopt a V-shaped corrugated structure, which is sandwiched between two cooling pipes. The V-shaped protrusions of the heat sink contact the cooling pipes and are welded at the contact point to achieve a stable installation and contact heat conduction. However, when the heat sink and cooling pipes adopt this connection structure, the contact area is small, the heat conduction efficiency is slow, and the connection fixed by welding is more troublesome to install, affecting the assembly efficiency during production.

[0004] Therefore, we propose a new type of automotive radiator core to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automotive radiator core to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A car radiator core includes several cooling pipes and heat dissipation fins distributed between adjacent cooling pipes. The upper and lower surfaces of the cooling pipes are uniformly provided with several outer ribs along the length direction, and the outer ribs are provided with slots. The heat dissipation fins adopt a V-shaped corrugated structure, and each corrugation peak forms a V-curve. The V-curve is matched and engaged with the slot. The upper and lower surfaces of the cooling pipes are also uniformly provided with several fins along the length direction, and the fins are used to press against the V-curve of the heat dissipation fin.

[0008] In a further embodiment, the outer ribs on the upper and lower surfaces of the cooling pipe are staggered, and the outer ribs on the opposite surfaces of adjacent cooling pipes are also staggered.

[0009] In a further embodiment, the length of the slot is equal to the width of the heat sink, and the outer circumference of the V-arc portion is in close contact with the inner wall of the slot.

[0010] In a further embodiment, the fins on the upper and lower surfaces of the cooling pipe are staggered, and the fins on the opposite surfaces of adjacent cooling pipes are also staggered.

[0011] In a further embodiment, the end of the fin away from the cooling pipe is provided with an arc-shaped end head, and the end head is in close contact with the inner circle side of the V-shaped arc portion.

[0012] In a further embodiment, the card slot has protrusions at both ends along its length, and the side of the protrusions closest to the card slot is rounded.

[0013] In a further embodiment, the card slot is provided with symmetrical convex arc portions on both sides.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a design where, when the heat sink is connected to the cooling pipe, each V-shaped arc of the heat sink can be engaged in a corresponding slot on the outer rib, thus limiting the heat sink's position. Simultaneously, when the two cooling pipes clamp the heat sink, the fins further tighten and limit its position, effectively preventing the heat sink from shifting within the cooling pipes. This not only facilitates assembly and connection, improving production efficiency, but also increases the contact area between the heat sink and the cooling pipes, thereby enhancing heat dissipation.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 A type of automotive radiator core includes several cooling pipes 1 and heat sinks 2 distributed between adjacent cooling pipes 1. The upper and lower surfaces of the cooling pipes 1 are uniformly provided with several outer ribs 11 along the length direction, and the outer ribs 11 are provided with slots 111. The heat sinks 2 adopt a V-shaped corrugated structure, and each protruding crest forms a V-arc portion 21. The V-arc portion 21 is matched and engaged with the slots 111. The outer ribs 11 on the upper and lower surfaces of the cooling pipes 1 are staggered, and the outer ribs 11 on the opposite sides of adjacent cooling pipes 1 are also staggered. The staggered spacing is equal to the spacing of the V-arc portions 21 of the heat sinks 2. Thus, when the two layers of cooling pipes 1 clamp the heat sinks 2, the V-arc portions 21 of the heat sinks 2 are correspondingly engaged in the slots 111 of the outer ribs 11, thereby restricting the heat sinks 2 and preventing them from swaying or shifting from side to side, eliminating the trouble of welding fixation.

[0027] For further details, please refer to Figure 5-6The length of the slot 111 is equal to the width of the heat sink 2, and the outer circle of the V-arc portion 21 is in close contact with the inner wall of the slot 111. The two sides of the slot 111 are symmetrically provided with convex arc portions 113. The convex arc portions 113 and the outer ribs 11 are in close contact with the V-arc portion 21, which helps to expand the contact area and thus improve the heat conduction efficiency.

[0028] Please see Figure 5-6 The card slot 111 has protrusions 112 at both ends along its length. The protrusions 112 limit the heat sink 2 to prevent it from shifting back and forth. The side of the protrusions 112 near the card slot 111 is rounded, which makes the open end of the card slot 111 larger and makes it easier for the V-arc part 21 to be inserted.

[0029] Please see Figure 1-4 Furthermore, the upper and lower surfaces of the cooling pipe 1 are uniformly provided with a number of fins 12 along the length direction, and the fins 12 are used to abut against the V-arc portion 21 of the heat sink 2. The fins 12 on the upper and lower surfaces of the cooling pipe 1 are staggered, and the fins 12 on the opposite sides of adjacent cooling pipes 1 are also staggered. The staggered spacing is equal to the spacing of the V-arc portion 21 of the heat sink 2, so that when the two layers of cooling pipes 1 clamp the heat sink 2, each fin 12 can abut against each V-arc portion 21 of the heat sink 2, thereby improving the limiting effect on the heat sink 2. In addition, the fins 12 divide the V-shaped area of ​​each heat sink 2 into two right-angled triangular areas, which helps to increase the contact rate between the entire core and the outside air, and further enhances the heat conduction effect.

[0030] Please also see Figure 5-6 The end of the fin 12 away from the cooling pipe 1 is provided with an arc-shaped end head 121, and the end head 121 is closely fitted with the inner circle side of the V-arc portion 21, which is conducive to increasing the contact area between the fin 12 and the heat sink 2, thereby improving the heat conduction efficiency.
