Description

Technical Field

[0001] This utility model belongs to the field of vehicle lighting technology, specifically the lighting for Sinotruk New Energy light trucks. Background Technology

[0002] Vehicle lights are tools for illuminating roads at night and for issuing various vehicle driving signals. New energy light trucks have power supply systems that support higher-power headlights, resulting in higher brightness. This design allows new energy light trucks to provide a longer lighting distance and a wider field of vision when driving at night, making driving safer for drivers. However, the higher power often leads to a large amount of heat generated when the headlights are working, causing the LED chip temperature to rise, which in turn affects its photoelectric conversion efficiency and lifespan. Therefore, it is necessary to improve the heat dissipation effect while making the headlights brighter in order to extend their lifespan and maintain their high-performance operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a Sinotruk New Energy light truck lamp that, while making the lamp brighter, improves its heat dissipation effect, maintains high-performance operation, and extends its service life.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A Sinotruk New Energy light truck lamp includes an LED lamp housing and a lamp body disposed on the LED lamp housing. A first heat-conducting column is disposed at the bottom of the lamp housing. A heat dissipation base is disposed at the bottom of the first heat-conducting column. Second and third heat-conducting columns are arranged at intervals on both sides of the bottom of the heat dissipation base. The second and third heat-conducting columns are arranged vertically downwards. Heat dissipation fins are evenly arranged from top to bottom on the outer surface of the second and third heat-conducting columns, with a gap between adjacent heat dissipation fins. The heat dissipation fins on the second and third heat-conducting columns are arranged at intervals. A first heat dissipation pipe is disposed at the bottom of the outer surface of the second and third heat-conducting columns, dividing the circumference equally. A second heat dissipation pipe is disposed at the end of the first heat dissipation pipe away from the second and third heat-conducting columns, arranged vertically downwards. The bottom end of the second heat dissipation pipe penetrates multiple layers of heat dissipation fins and connects to the upper surface of the lowest heat dissipation fin. The outer surface of the second heat dissipation pipe abuts against the heat dissipation fins. A cooling fan assembly is disposed on the outer side of multiple heat dissipation fins.

[0005] Furthermore, the outer surfaces of the second and third heat-conducting pillars are provided with multiple connecting plates that are equally divided into circumferences, and right angles are formed between adjacent connecting plates. Each layer of heat sink is equally divided into circumferences on the outer surfaces of the second and third heat-conducting pillars and is located between adjacent connecting plates. The heat sink is connected to the connecting plates.

[0006] Furthermore, the cooling fan assembly includes a fixing block, a housing, mounting holes, a central connector, a radiating connector, and a cooling fan. The fixing block is symmetrically arranged at the top of the outermost heat sink and the bottom of the outermost heat sink. The housing has connection holes at its four corners and is fixedly connected by bolt fixing blocks. The mounting hole is located in the middle of the housing. The central connector has the center of the mounting hole. The radiating connector is arranged in a ring on the outer surface of the central connector. The end of the radiating connector away from the central connector is fixedly connected to the inner wall of the mounting hole. The cooling fan is fixed on the central connector.

[0007] The beneficial effects of this utility model are:

[0008] This invention utilizes a combination of a first heat-conducting pillar, a heat dissipation base, a second heat-conducting pillar, a third heat-conducting pillar, a heat sink, a first heat dissipation pipe, a second heat dissipation pipe, and a cooling fan assembly. Heat from the vehicle headlight is conducted through the first heat-conducting pillar to the heat dissipation base, and then transferred through the second and third heat-conducting pillars, as well as the first and second heat dissipation pipes, to the heat sink for heat dissipation. With the same projected area, this effectively increases the heat dissipation area, improving heat dissipation efficiency and effect. Furthermore, forced heat dissipation through the cooling fan assemblies on both sides further enhances the heat dissipation effect, resulting in a brighter headlight with better heat dissipation and higher efficiency, maintaining high-performance operation and extending service life.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Reference Figure 1-3 As shown, the Sinotruk New Energy light truck lamp includes an LED lamp housing 1 and a lamp body 2 mounted on the LED lamp housing 1. A first heat-conducting column 3 is located at the bottom of the lamp housing 1, and a heat dissipation base 4 is located at the bottom of the first heat-conducting column 3. Second heat-conducting columns 5 and third heat-conducting columns 6 are arranged at intervals on both sides of the bottom of the heat dissipation base 4, with the second and third heat-conducting columns 5 and 6 arranged vertically downwards. The first heat-conducting column 3, the second heat-conducting column 5, the third heat-conducting column 6, and the heat dissipation base 4 are all made of materials with excellent thermal conductivity, such as copper and aluminum. The first heat-conducting column 3 absorbs and conducts the heat emitted by the lamp body 2 during operation to the heat dissipation base 4, and dissipates the heat through heat dissipation. Heat is transferred from the base 4 to the second heat-conducting pillar 5 and the third heat-conducting pillar 6 to increase the heat dissipation area and improve heat dissipation performance and efficiency. Heat sinks 7, made of aluminum, are evenly arranged from top to bottom on the outer surfaces of the second and third heat-conducting pillars 5 and 6. Spacing between adjacent heat sinks 7 increases the contact area between the heat sinks 7 and the outside environment, resulting in a larger heat dissipation area under the same projection. The heat sinks on the second and third heat-conducting pillars 5 and 6 are spaced apart, allowing heat to be transferred layer by layer from the second and third heat-conducting pillars 5 and 6 to the heat sinks 7 for heat dissipation, further increasing the heat dissipation area. This design improves heat dissipation effect and efficiency. First heat dissipation pipes 8 are evenly spaced circumferentially at the bottom of the outer surfaces of the second and third heat-conducting pillars 5 and 6. A second heat dissipation pipe 9, arranged vertically downwards, is located at the end of the first heat dissipation pipe 8 away from the second and third heat-conducting pillars 5 and 6. Both the first and second heat dissipation pipes 8 and 9 are made of copper. The bottom end of the second heat dissipation pipe 9 penetrates multiple layers of heat sink 7 and connects to the upper surface of the lowest heat sink 7. The outer surface of the second heat dissipation pipe 9 abuts against the heat sink 7. The first and second heat dissipation pipes 8 and 9 are evenly spaced circumferentially, allowing material on the second and third heat-conducting pillars 5 and 6 to pass through multiple first heat dissipation pipes. 8. The second heat pipe 9 quickly transfers heat to the heat sink 7, further increasing the heat dissipation area and improving its heat dissipation effect and efficiency. Multiple heat sinks 7 are equipped with heat dissipation fan assemblies 10 on their outer sides. The heat dissipation fan assemblies 10 on both sides cooperate with each other to force air cooling. The airflow passes between the spaced heat sinks 7 and contacts the second heat conduction column 5, the third heat conduction column 6 and the outer surface of the second heat pipe 9, increasing the contact area of ​​the airflow and making its cooling effect better. Their cooperation further improves the heat dissipation effect of the headlight, making the headlight brighter while having a better heat dissipation effect and higher heat dissipation efficiency, maintaining high-performance operation and extending service life.

[0016] Multiple connecting plates 11 are evenly distributed around the outer surface of the second heat-conducting pillar 5 and the third heat-conducting pillar 6, forming right angles between adjacent connecting plates 11. Each heat sink 7 is evenly distributed around the outer surface of the second heat-conducting pillar 5 and the third heat-conducting pillar 6, and is located between adjacent connecting plates 11. The heat sink 7 is connected to the connecting plates 11, which are made of aluminum. The heat sink 7 and the adjacent connecting plates 11 form a stable triangular structure. The connection plates 11 make the structure of the heat sink 7 and the second heat-conducting pillar 5 and the third heat-conducting pillar 6 more stable, with higher structural strength, less prone to deformation and damage due to external forces, and improve its service life.

[0017] The cooling fan assembly 10 includes a fixing block 1001, a housing 1002, mounting holes 1003, a central connector 1004, a radiating connector 1005, and a cooling fan 1006. The fixing blocks 1001 are symmetrically arranged at the top of the outermost heat sink 7 and the bottom of the outermost heat sink 7. The housing 1002 has connecting holes 1007 at its four corners, which are fixedly connected by bolts to the fixing blocks 1001. The fixing blocks 1001 have positioning holes that match the connecting holes 1007. Bolts pass through the connecting holes 1007 and are threaded into the positioning holes. The mounting holes 1003 are formed in the housing. At the center of 1002, the central connector 1004 is provided with the center of the mounting hole 1003. The divergent connector 1005 is arranged in a ring on the outer surface of the central connector 1004. The end of the divergent connector 1005 away from the central connector 1004 is fixedly connected to the inner wall of the mounting hole 1003. The cooling fan 1006 is fixed on the central connector 1004. The drive motor of the cooling fan 1006 is fixed on the central connector 1004. The airflow driven by the cooling fan 1004 is parallel to the heat sink 7 and contacts the heat sink 7, the second heat conduction column 5, the third heat conduction column 6 and the second heat dissipation pipe 9 for cooling.
