Description

Technical Field

[0001] This utility model relates to the field of profile radiator technology, specifically to radiator sealing structure. Background Technology

[0002] The profile heat sink mainly consists of a light source plate 3, a profile heat sink body 1, a profile cover plate 4, and a lampshade 2. The light source plate 3 is located inside the profile heat sink body 1. The lampshade 2 is installed below the profile heat sink body. The profile cover plate 4 is located on both sides of the lampshade 2. The top of the profile heat sink body 1 has a regular heat dissipation fin structure to increase the heat dissipation area, such as... Figure 6 and Figure 7 As shown, it is commonly found in lighting fixtures or electronic devices;

[0003] Currently, there are two main types of sealing methods for profile radiators on the market: the first type of radiator does not have a waterproof structure, such as... Figure 5 As shown, liquid waterproof sealant is generally used to coat all the components. The operation of coating all the components with liquid waterproof sealant requires a special dispensing machine. The cost of cutting the waterproof sealant is higher than that of the sealant strip 5.

[0004] The second method is to use a sealing strip 5 for sealing, such as Figure 6 As shown, the sealing strip 5 is placed at the connection between the lampshade 2 and the profile heat sink body 1, and then the screw 9 is installed on the surface of the lampshade 2 for fastening. This method requires the screw holes (threaded holes) to be machined on the profile heat sink body 1 and the screw through holes to be machined on the profile cover plate 4 for installation.

[0005] However, the first sealing method requires a special dispensing machine to apply the adhesive evenly. If the equipment is not precise or the operation is improper, the adhesive layer is prone to uneven thickness, forming tiny leakage channels, which affects the sealing effect. The second sealing method has insufficient machining precision of the screw holes or inconsistent torque, which leads to uneven pressure on the adhesive strip (such as some areas being over-compressed while others are not in full contact), forming leakage channels, which affects the sealing performance.

[0006] To address the aforementioned shortcomings, we need to propose a radiator sealing structure. Utility Model Content

[0007] The purpose of this utility model is to provide a radiator sealing structure, which achieves a double seal between the lampshade and the radiator body through the cooperation of sealing strips, snap-fit ​​parts and profile cover plate, and is easy to install, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a radiator sealing structure, including a sealing structure body installed on both sides of the profile radiator body, the sealing structure body including a sealing strip installed between the profile radiator body and the lamp cover and a snap-fit ​​component located inside the profile radiator body, and the sealing strip and the snap-fit ​​component are both connected to the profile radiator body through a profile cover plate, and the snap-fit ​​component is fastened to the profile cover plate.

[0009] Preferably, the sealing strip is cylindrical, and the two sides of the profile radiator body are provided with grooves for installing the sealing strip.

[0010] Preferably, the snap-fit ​​component is a T-shaped structure composed of a horizontal part and a vertical part of the adhesive strip, and the lower end of the vertical part of the adhesive strip is integrally formed with a snap-fit ​​protrusion.

[0011] Preferably, the profile cover plate includes a horizontal cover plate portion and a vertical cover plate portion, the horizontal cover plate portion and the vertical cover plate portion forming a T-shaped structure, and a cover plate protrusion is integrally formed on one side of the vertical cover plate portion.

[0012] Preferably, the main body of the profile radiator has an installation cavity for installing the snap-on rubber parts and the vertical part of the cover plate, and the protrusion of the cover plate and the protrusion of the rubber strip are fastened together in the installation cavity.

[0013] Preferably, the mounting cavity is provided with a clearance recess on one side of the cover plate protrusion for the cover plate protrusion to avoid obstruction when it moves, and the clearance recess is arc-shaped.

[0014] Preferably, the lower surface of the end of the cover plate that contacts the lampshade is provided with an inclined surface, and the cover plates and buckle parts on both sides of the main body of the profile heat sink are symmetrically arranged.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a radiator sealing structure, including a sealing structure body installed on both sides of the profile radiator body 1. The sealing structure body includes a sealing strip 5 installed between the profile radiator body 1 and the lamp cover 2, and a snap-fit ​​component 6 located inside the profile radiator body 1. Both the sealing strip 5 and the snap-fit ​​component 6 are connected to the profile radiator body 1 through a profile cover plate 4, and the snap-fit ​​component 6 is fastened to the profile cover plate 4.

[0028] The sealing structure on both sides of the radiator body 1 is mainly composed of sealing strips 5 and snap-fit ​​parts 6, which are combined with the radiator cover plate 4. The snap-fit ​​parts 6 are fastened to the radiator cover plate 4, so that the pressure applied by the radiator cover plate 4 to the snap-fit ​​parts 6 and the sealing strips 5 is uniform. The double sealing of the snap-fit ​​parts 6 and the sealing strips 5 effectively increases the sealing effect of the radiator body 1.

[0029] The sealing strip 5 is cylindrical, and the two sides of the profile radiator body 1 are provided with grooves for installing the sealing strip 5, such as... Figure 3 As shown, after the sealing strip 5 is installed in the groove, at least one-fifth of the diameter of the sealing strip 5 is exposed outside the groove. When the lampshade 2 is combined with the profile heat sink body 1, the lampshade 2 squeezes the sealing strip 5, and the toughness of the sealing strip 5 is used to increase the sealing between the lampshade 2 and the profile heat sink body 1.

[0030] The snap-fit ​​component 6 is a T-shaped structure composed of a horizontal adhesive strip portion 61 and a vertical adhesive strip portion 62. A snap-fit ​​protrusion 63 is integrally formed at the lower end of the vertical adhesive strip portion 62. The profile cover plate 4 includes a horizontal cover plate portion 41 and a vertical cover plate portion 42, which form a T-shaped structure. A cover plate protrusion 43 is integrally formed on one side of the vertical cover plate portion 42. Figure 3 As shown, the T-shaped structure of the snap-fit ​​component 6 is matched with the T-shaped structure of the profile cover plate 4, and the snap-fit ​​protrusion 63 is matched with the protrusion 43 of the cover plate, which facilitates the snap-fit ​​component 6 and the profile cover plate 4 to be snapped together, improves the convenience of installing the profile cover plate 4, and at the same time ensures the uniformity of the force applied between the profile cover plate 4 and the snap-fit ​​component 6.

[0031] The profile radiator body 1 has an installation cavity 7 for mounting the snap-fit ​​adhesive part 6 and the vertical part of the cover plate 42. The cover plate protrusion 43 and the adhesive strip protrusion are engaged within the installation cavity 7. Figure 3 As shown, the upper end of the mounting cavity 7 matches the horizontal part 61 of the adhesive strip, and the lower end of the mounting cavity 7 is set with an opening. The opening position allows the vertical part 62 of the adhesive strip and the vertical part 42 of the cover plate to enter, so that the snap-fit ​​adhesive part 6 can be fastened and fixed in the mounting cavity 7 by utilizing the special shape of the mounting adhesive and will not move. Then, the profile cover plate 4 is fastened to the snap-fit ​​adhesive part 6, so that the profile cover plate 4 can be fixed on the profile heat sink body 1.

[0032] The mounting cavity 7 is provided with a clearance recess 8 on one side of the cover plate protrusion 43 to allow the cover plate protrusion 43 to move and avoid obstruction. The clearance recess 8 is arc-shaped. When disassembling the profile cover plate 4, the clearance recess 8 allows the cover plate protrusion 43 to have a certain amount of room to move by utilizing the movement of the inclined surface 44 between the fastening protrusion 63 and the cover plate protrusion 43, so that the cover plate protrusion 43 can be pulled out from the mounting cavity 7.

[0033] The lower surface of the end of the cover plate horizontal part 41 that contacts the lamp cover 2 is provided with a slope 44. The profile cover plate 4 and the snap-fit ​​rubber parts 6 located on both sides of the profile heat sink body 1 are symmetrically arranged. By setting the slope 44, the lower surface of the profile heat sink body 1 has a smooth slope, avoiding scratches to the equipment or installers during heat sink installation due to sharp corners.

[0034] It should be noted that the sealing structure of this utility model is applicable to profile heat sinks, which are mainly composed of a light source plate 3, a profile heat sink body 1, a profile cover plate 4, and a lampshade 2. The light source plate 3 is located inside the profile heat sink body 1, the lampshade 2 is installed below the profile heat sink body, the profile cover plate 4 is located on both sides of the lampshade 2, and the profile heat sink body 1 has a regular heat dissipation fin structure on its upper part to increase the heat dissipation area.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
