Technical Field

[0001] This utility model relates to the field of automotive LED lighting technology, and in particular to a heat dissipation module for automotive LED lighting with a heat pipe and a circular continuous snap-fit ​​sheet. Background Technology

[0002] Automotive LED heat pipes are components used for efficient heat dissipation, primarily in LED automotive lights, to address the heat generated by LED light sources during operation. Through their unique structural design, heat pipes can rapidly conduct and disperse the heat generated by the LEDs, thereby maintaining the normal operating temperature of the automotive lights.

[0003] To facilitate heat conduction, the heat dissipation substrate and the heat sink holder are usually welded together. However, the welding process requires a high level of skill, and after welding, the contact area between the heat dissipation substrate and the heat sink holder is small, which affects the heat dissipation effect. To address this, a heat dissipation module for automotive LED lights with a heat pipe and a circular continuous snap-fit ​​sheet is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the small contact area between the heat dissipation substrate and the heat sink holder, which affects the heat dissipation effect. The invention proposes a heat dissipation module for automotive LED lights with a heat pipe and a circular continuous snap-fit ​​sheet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat dissipation module for automotive LED lights with heat pipes and circular continuous snap-fit ​​sheets includes a heat dissipation substrate. An LED bead is fixedly mounted on one side of the heat dissipation substrate, and the same U-shaped heat pipe is provided on both sides and the bottom of the heat dissipation substrate. The heat pipe is fixed to the heat dissipation substrate.

[0007] It also includes a continuously snap-fit ​​stamped heat sink holder, which is located at the bottom of the heat pipe for heat dissipation.

[0008] As a further embodiment of this utility model, the heat sink holder includes multiple heat sinks, a U-shaped groove is provided in the middle of the heat sink, a U-shaped partition is integrally formed on one side of the heat sink, a card is integrally formed on one side of the heat sink, a through slot is provided on the surface of the card, and a positioning block is integrally formed on the bottom of the heat sink.

[0009] As a further improvement of this utility model, two adjacent heat sinks are abutted by a partition, and adjacent cards are inserted into the card slot and secured by a positioning block.

[0010] As a further embodiment of this invention, the bottom of the heat pipe is located inside a U-shaped groove and is soldered with high-temperature solder paste.

[0011] As a further improvement of this invention, the heat pipe is made of copper.

[0012] As a further improvement of this invention, the heat pipe is soldered to the heat dissipation substrate using high-temperature solder paste.

[0013] In this application, the heat dissipation substrate and the heat pipe are connected and then soldered with high-temperature solder paste. The assembled heat dissipation substrate and heat pipe are then inserted into the U-shaped groove of the heat sink holder and connected again with high-temperature solder paste, thereby achieving an integrated heat dissipation module. This reduces thermal resistance, improves heat dissipation, and makes the heat dissipation substrate and heat sink holder more firmly connected, improving the mechanical strength of the overall structure. The integrated design can also better resist vibration and impact, making it suitable for high-vibration environments.

[0014] Beneficial effects: In this utility model, the heat dissipation module of automotive LED light heat pipe plus circular continuous snap-fit ​​sheet, through the cooperation between heat dissipation substrate, heat pipe and heat sink seat, the heat pipe can increase the heat conduction effect between heat dissipation substrate and heat sink seat, and improve the heat dissipation effect.

[0015] In this utility model, the heat dissipation module of automotive LED lamp heat pipe with circular continuous snap-fit ​​sheet is designed to weld the heat dissipation substrate and the heat dissipation fin seat together, so that the heat dissipation substrate and the heat dissipation fin seat are more firmly connected, improving the mechanical strength of the overall structure. The integrated design can also better resist vibration and impact, making it suitable for high vibration environments.

[0016] In this invention, the heat dissipation substrate, heat pipe and heat sink holder are used in combination to increase the heat conduction between the heat dissipation substrate and the heat sink holder, thereby improving the heat dissipation effect. At the same time, welding makes the heat dissipation substrate and heat sink holder more firmly connected, improving the mechanical strength of the overall structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1-3 A heat dissipation module with a heat pipe and a circular continuous snap-fit ​​sheet includes: a heat dissipation substrate 1, on one side of the heat dissipation substrate 1, an LED bead 3 is fixedly installed using a solder paste welding process, the LED bead 3 is a light source for emitting light, and the same U-shaped heat pipe 2 is provided on both sides and the bottom of the heat dissipation substrate 1, and the heat pipe 2 is fixed to the heat dissipation substrate 1.

[0023] It also includes a heat sink seat 4 that is continuously snapped together and stamped. The heat sink seat 4 is set at the bottom of the heat pipe 2 for heat dissipation. Through the cooperation between the heat dissipation substrate 1, the heat pipe 2 and the heat sink seat 4, the heat pipe 2 can increase the heat conduction effect between the heat dissipation substrate 1 and the heat sink seat 4, thereby improving the heat dissipation effect.

[0024] This application can be used in the field of automotive LED lights, or in other fields applicable to this application.

[0025] Example 2, Reference Figures 1-3 Based on Example 1, an improved automotive LED lamp heat pipe with circular continuous snap-fit ​​heat dissipation module is applied to the automotive LED lamp field. The heat sink base 4 includes multiple heat sinks 5. A U-shaped groove is provided in the middle of the heat sink 5. A U-shaped partition 6 is integrally formed on one side of the heat sink 5. A card 7 is integrally formed on one side of the heat sink 5. A through slot 8 is provided on the surface of the card 7. A positioning block 9 is integrally formed on the bottom of the heat sink 5. The heat sink 5 is made by continuous stamping and snap-fit ​​process. The continuous stamping and snap-fit ​​process can manufacture heat sinks 5 with complex shapes and fine structures, and has a higher degree of design freedom. In contrast, the extrusion cutting process is limited by the mold and it is difficult to realize complex designs. The continuous snap-fit ​​stamping fins are thinner and denser, increasing the surface area and convection efficiency.

[0026] In this utility model, two adjacent heat sinks 5 are in contact with each other by a partition 6, and adjacent cards 7 are inserted into the card slots 8 and locked by positioning blocks 9.

[0027] In particular, the bottom of the heat pipe 2 is located inside a U-shaped groove and is soldered with high-temperature solder paste.

[0028] It should be noted that heat pipe 2 is made of copper, which has good thermal conductivity and facilitates heat dissipation.

[0029] In this invention, the heat pipe 2 and the heat dissipation substrate 1 are soldered together by high-temperature solder paste, thereby achieving an integrated heat dissipation module, reducing thermal resistance, improving heat dissipation effect, and making the heat dissipation substrate 1 and the heat sink 4 more firmly connected, improving the mechanical strength of the overall structure. The integrated design can also better resist vibration and impact, making it suitable for high vibration environments.

[0030] However, as is well known to those skilled in the art, the working principle and wiring method of LED 3 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
