Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, and in particular to a car radiator strip. Background Technology

[0002] For current automotive radiators, there is a 2-3mm gap between the water chamber and the main fin, which is sealed using a rubber strip. These sealing rubber strips are generally classified into two types based on their basic cross-sectional shape: "D" type and "O" type, with the outer edge of the cross-section near the corner of the main fin. "D" type sealing rubber strips are commonly used in the assembly of the water chamber and the main fin in automotive radiators. In addition, ordinary "O" type sealing rubber strips have also been widely used in recent years. Experience shows that due to the rounded corners and uneven bottom plane of the main fin, "D" type and ordinary "O" type sealing rubber strips are prone to twisting and shrinkage at the corners during assembly, resulting in poor sealing and affecting the overall sealing performance.

[0003] For example, an embedded automotive radiator sealing strip, disclosed in CN210196441U, includes a sealing strip body. The sealing strip body comprises an outer rolled piece and a locking piece. The outer rolled piece is fixedly disposed at one end of the sealing strip body and is integrally formed with the sealing strip body by injection molding. The locking piece is fixedly disposed on the other side surface of the outer rolled piece and is integrally formed with the sealing strip body by injection molding. A fixing ring is fixedly disposed on one side surface of the sealing strip body, and a fixing chamfer is fixedly disposed on the lower surface of the fixing ring. The redesigned structure of the sealing strip prevents the bolt from damaging the sealing strip body when it is fixed with bolts. At the same time, the elastic structure inside the sealing strip body provides a certain tightening effect during bolt tightening, improving the sealing performance and extending the service life of the sealing strip.

[0004] In practical applications, the above-mentioned technical solutions are prone to problems such as deformation affecting sealing performance.

[0005] Therefore, it is necessary to invent a car radiator strip to solve the above problems. Utility Model Content

[0012] Preferably, there are multiple strip grooves, and the multiple strip grooves are arranged at equal intervals from top to bottom.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model features a rubber strip body with an arc-shaped surface at the top. This arc-shaped surface ensures that the rubber strip body can have the variability of a "D"-shaped sealing strip. By providing deformable parts on both sides of the rubber strip body, when the top of the rubber strip body is squeezed and deformed, the deformable parts deform in the direction of the rubber strip body, thereby achieving a seal at the connection between the rubber strip body and the radiator. This effectively solves the problem of gaps between the rubber strip body and the radiator caused by twisting, which affects the sealing performance.

[0015] 2. This utility model provides a first guide groove on the outer side of the adhesive strip body and a second guide groove on the inner side of the adhesive strip body. Both the first and second guide grooves are designed with a "<" shape, and the groove area of ​​the second guide groove is larger than that of the first guide groove. This ensures that the adhesive strip body can collapse and deform inward when squeezed, thereby limiting the deformation range of the adhesive strip body and controlling its deformation range to ensure its sealing effect.

[0020] 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.

[0021] This utility model provides, for example Figure 1-3 The illustrated automotive radiator strip includes a strip body 1, which is a hollow structure. The top of the strip body 1 is provided with an arc-shaped surface 2, and both sides of the strip body 1 are provided with deformable parts 3. The deformable parts 3 are provided with an inclined structure, and the bottom end of the deformable parts 3 is provided with a rounded corner 12. The inner sidewall of the deformable parts 3 is provided with an arc-shaped structure. The arc-shaped structure design avoids cracking and damage at the end of the deformable parts 3 during transportation or installation.

[0022] Specifically, a deformation groove 4 is provided at the connection of the deformation parts 3 on both sides of the arc surface 2, and the deformation groove 4 is set as a "√" shaped structure. A fitting plane 5 is provided at the top of the deformation part 3. The fitting plane 5 can ensure stable contact between the top of the adhesive strip body 1 and the heat sink.

[0023] More specifically, a first guide groove 6 is provided in the middle of both sides of the adhesive strip body 1. The first guide groove 6 is configured with a "<" shaped structure. A second guide groove 7 is provided in the middle of the inner wall of both sides of the adhesive strip body 1. The second guide groove 7 is configured with a "<" shaped structure. The groove width of the second guide groove 7 is greater than that of the first guide groove 6. The second guide groove 7 cooperates with the first guide groove 6 to guide the adhesive strip body 1 to deform inward.

[0024] Furthermore, strip grooves 8 are fixedly provided on both bottom sides of the rubber strip body 1. There are multiple strip grooves 8, and the multiple strip grooves 8 are arranged at equal intervals from top to bottom. The arrangement of the strip grooves 8 allows the rubber strip body 1 to deform to a certain extent when subjected to a force in the tilting direction, so as to achieve the effect of relieving force.

[0025] Furthermore, the lower surface of the adhesive strip body 1 is provided with multiple grooves 9, which are equally spaced and are all square in structure. The bottom of each groove 9 is provided with a transverse deformation groove 10, which is diamond in structure. The transverse deformation groove 10 causes the adhesive strip body 1 to deform inward when subjected to a transverse force. After deformation, the inner wall of the transverse deformation groove 10 forms wrinkles, which contact the radiator to increase the friction between them, thereby preventing the adhesive strip from loosening. The lower surface of the adhesive strip body 1 is provided with multiple tear grooves 11, which are strip-shaped and are staggered with the grooves 9. The tear grooves 11 allow users to adjust the length of the adhesive strip body 1 according to their needs.

[0026] Working principle of this utility model:

[0027] This invention features a rubber strip body 1 with an arc-shaped surface 2 at its top. This arc-shaped surface 2 ensures the rubber strip body 1 possesses the variability characteristic of a "D"-shaped sealing strip. Deformable portions 3 are provided on both sides of the rubber strip body 1. When the top of the rubber strip body 1 is compressed and deformed, the deformable portions 3 deform in the direction of the rubber strip body 1, thus sealing the connection between the rubber strip body 1 and the radiator. This effectively solves the problem of gaps between the rubber strip body 1 and the radiator caused by twisting, affecting sealing performance. A first guide groove 6 is provided on the outer side of the rubber strip body 1, and a second guide groove 7 is provided on the inner side. Both the first and second guide grooves are "<" shaped, and the opening area of ​​the second guide groove 7 is larger than that of the first guide groove 6. This ensures that the rubber strip body 1 can collapse inwards when compressed, thereby limiting the deformation range of the rubber strip body 1 and controlling its deformation range to guarantee its sealing effect.
