Description

Technical Field

[0001] The utility model relates to a buckled type liquid cooling radiator for a vehicle lamp, belonging to the technical field of liquid cooling radiators. Background Art

[0002] With the rapid development of automobile technology, the functions of smart car lights are becoming increasingly enhanced, integrating multiple functions such as screen projection, indication, and interaction. However, if the high temperature and heat dissipation problems caused by high-load work are not effectively solved, their performance and life will be affected. At present, there are mainly two types of car light radiators: air cooling and liquid cooling. Air cooling uses the airflow of a fan or air duct to dissipate heat, and the heat dissipation efficiency is relatively low; liquid cooling uses liquid (such as water, oil or other coolants) to absorb and take away heat, which is suitable for high-performance equipment and high-load environments. However, liquid cooling is prone to leakage, causing equipment failure. The prior art mainly uses high-temperature welding technology to seal the liquid-cooled radiator, and its disadvantages and shortcomings are:

[0003] First, the high-temperature welding process causes uneven release of thermal stress, which leads to deformation of the material after welding. For lamp holders with high dimensional accuracy requirements, post-welding machining is usually required, which is costly and has low production efficiency.

[0004] Secondly, welding has high requirements on the weldability of materials and the material selection is limited. For example, the die-cast materials suitable for lamp holders usually have failure modes such as bulging and inner cavity blockage after brazing, and the product yield is low.

[0005] Third, the welding process consumes a lot of energy, which will produce welding slag and lead to poor cleanliness of the inner cavity. Summary of the invention

[0006] The utility model aims to provide a buckle-type liquid-cooled radiator for a vehicle lamp, which can reliably realize the sealing of the coolant and has the advantages of efficient heat dissipation performance, excellent inner cavity cleanliness, wide material selection and low cost.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Buckle type car light liquid cooling radiator, including:

[0009] A base, the base including a lamp holder, and an open shell extending outwardly from one end surface of the lamp holder, the interior of the shell forming a cavity for filling with coolant, ribs arranged in the cavity, a buckling protrusion arranged along the circumference of the opening of the shell, and a sealing ring groove arranged between the buckling protrusion and the cavity;

[0011] An upper cover, the upper cover comprising a cover plate, the cover plate is placed above the cavity and the sealing ring is pressed into the sealing ring groove through the first end surface of the cover plate, a nozzle is arranged on the second end surface of the cover plate, the nozzle passes through the first end surface and the second end surface of the cover plate and is connected with the cavity;

[0012] The buckled sheet metal is a shell with a through hole, a multi-tooth structure is processed at the hole opening at one end of the through hole, and a flange extending toward the center of the through hole is provided at the hole opening at the other end of the through hole (it can also be understood as an inward flange of the through hole hole opening), the buckling protrusion and the cover plate are located on the inner side of the through hole wall of the buckled sheet metal, and the multi-tooth structure is pressed against the surface of the buckling protrusion after being bent and deformed, and the flange is pressed against the second end face of the cover plate.

[0013] Furthermore, the ribs are multiple sheet-like structures that are perpendicular to the end surface of the lamp holder and distributed in parallel in the cavity.

[0014] Furthermore, the nozzle includes a coolant inlet nozzle and a coolant outlet nozzle.

[0015] Furthermore, a reinforcing rib is provided on the second end surface of the cover plate.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above-mentioned technical ideas of the present invention, various modifications, substitutions and changes made according to the common technical knowledge and customary means in the field are included in the scope of the present invention.

[0029] The clamping type liquid-cooled radiator for the headlight provided in this embodiment optimizes the design of the clamping sheet metal 1 with a multi-tooth structure 11, and mechanically clamps the sealing ring 3 through the clamping sheet metal 1 to ensure the sealing of the liquid-cooled radiator. The liquid-cooled radiator for the headlight has the advantages of low production energy consumption, excellent cleanliness, a wide range of material selection, high assembly efficiency and low cost.

[0030] like Figures 1 to 7 As shown, the design scheme of the buckled type vehicle lamp liquid cooling radiator includes a buckled sheet metal 1, an upper cover 2, a sealing ring 3 and a base 4.

[0031] like Figure 5 , one end of the buckled sheet metal 1 is a multi-tooth structure 11 along the circumferential direction (it should be noted that, Figure 5 The multi-tooth structure 11 in the buckled sheet metal 1 has been bent and deformed), and the liquid cooling radiator can be sealed by mechanical buckling of the buckled sheet metal 1, such as Figure 4 That is, the upper cover 2 and the pressing protrusion 43 are pressed tightly by the multi-tooth structure 11 and the flange 12 of the pressing sheet metal 1, thereby ensuring that the sealing ring 3 is firmly confined between the upper cover 2 and the base 4, thereby achieving sealing of the coolant in the cavity 42.

[0032] like Figure 7 Through optimized design, the base 4 integrates the cavity 42 for liquid cooling, the fins 41 and the lamp holder 44 into one body, thereby realizing one-piece die-casting. Figure 6 The upper cover 2 integrates the nozzle 21 and the cover plate 22 into one body, realizing one-piece injection molding.

[0033] like Figure 5A multi-tooth structure 11 is designed on the buckled sheet metal 1, and the sealing of the base 4 and the cover 2 is achieved by mechanically buckling the sealing ring 3, which can solve the sealing problem of the liquid cooling radiator and has the advantages of low production energy consumption, wide material selection, and easy rework.

[0034] The structural design of the base 4: Figure 7 A cavity 42 is provided above the base 4 as a flow channel for the coolant. The groove space formed by the cavity 42 is provided with ribs 41, which can efficiently conduct heat to the fluid side, while increasing the contact area of ​​the coolant and enhancing heat exchange. A sealing ring groove is provided along the circumferential direction on the outer side of the groove for placing the sealing ring 3. A pressing protrusion 43 is provided along the circumferential direction on the outer side of the groove as a surface for the multi-tooth structure 11 on the sheet metal 1 to fit when the teeth are closed, that is, the multi-tooth structure 11 is pressed against the surface of the pressing protrusion 43 after bending and deforming, as shown in FIG. Figure 4 shown.

[0035] Design of the buckled sheet metal 1 structure: Figure 4 and Figure 5 The buckled sheet metal 1 has a through hole, and a groove is formed on the inner wall of the through hole along the circumferential direction. One end of the groove (corresponding to a hole position of the through hole) is provided with a circle of multi-tooth structure 11, and the teeth are rectangular teeth, and the teeth are arranged at equal intervals to ensure that the sealing ring 3 can be evenly stressed during compression. The other end of the groove is a flange 12 (corresponding to another hole position of the through hole, forming a circle of inward flange structure). The multi-tooth structure 11 and the flange 12 after bending and deformation are in Figure 4 A C-shaped structure is formed on the cross section of the middle buckling sheet metal 1, thereby pressing the upper end surface of the cover plate 22 and the lower end surface of the buckling protrusion 43 tightly between the two. During assembly, the base 4 and the upper cover 2 are tightly pressed together by mechanical buckling, so that the sealing ring 3 is subjected to sufficient compression force to ensure that the liquid in the sealing cavity 42 is sealed. The structural design of the buckling sheet metal 1 is simple and clear. When the sealing ring 3 needs to be replaced or repaired, the multi-tooth structure 11 is bent and deformed again to separate it from the end surface of the buckling protrusion 43, and it can be easily disassembled or installed.

[0036] Structural design of the upper cover 2: The upper cover 2 integrates the nozzle 21 and the cover plate 22 into one body. The integrated design of the cover plate 22 and the nozzle 21 can simplify the assembly process, improve production efficiency, and reduce production costs. Figure 6 Reinforcing ribs are provided on the cover plate 22 to increase the strength and rigidity of the upper cover 2 without increasing the wall thickness, thereby preventing deformation and warping.

[0037] The above is the main concept of the present utility model, and all buckle-type liquid-cooled radiators for vehicle lights designed based on the concept of the present utility model fall within the protection scope of the present utility model.
