The plurality of heat conducting pipes 10 are arranged on the fixing plate 1. One end of the heat conducting pipe 10 passes through the first fin group 2, and the other end passes through the second fin group 3, so that the fixing plate 1 is fixedly connected with the first fin group 2 and the second fin group 3 respectively through the heat conducting pipe 10. The first fin group 2 is provided with a first receiving groove 21 for installing a light source 7. The second fin group 3 A second accommodating groove 31 is provided, and an air guide member 4 and an air expelling member 5 are installed in the second accommodating groove 31 from the inside to the outside. The air guide member 4 is used to guide the airflow driven by the air expelling member 5 to diffuse around; specifically, the air expelling member 5 drives the external cold air flow to enter from the end of the heat dissipation structure, and then diffuses to the surroundings of the second fin group 3 under the guidance of the air guide member 4. Therefore, the heat dissipation structure not only has high heat dissipation efficiency, but also uniform heat dissipation; in addition, it does not need to install a cooling fan on the outside of the fin group, so it can effectively reduce the volume of the heat dissipation structure while improving the heat dissipation efficiency.

[0028] As attached Figure 2 and attached Figure 5 As shown, the air guide member 4 is mainly composed of a plurality of annular portions 41 with inconsistent diameters, which are integrally formed. The diameters of the plurality of annular portions 41 gradually increase along their axial direction, so that a step 42 is formed at the connection between adjacent annular portions 41. The air guide member 4 is in the shape of a trumpet with "one end small and the other end large", thereby guiding the wind drive member to drive the air volume to diffuse to the surroundings to each fin.

[0029] As attached Figure 3 , Attachment Figure 4 , Attachment Figure 6 and attached Figure 7 As shown, a seat body 6 is fixedly mounted on the fixing plate 1, and a mounting hole 11 is penetrated on the fixing plate 1 for part of the seat body 6 to pass through. After the seat body 6 passes through the mounting hole 11, one end portion thereof is accommodated in the first accommodating groove 21 and fixedly connected to the light source 7, specifically, the end portion is the second heat sink group 63 below.

[0030] In this embodiment, the other end of the seat body 6 is accommodated in the second accommodating groove 31 and is fixedly connected to the wind guide member 4 and the wind expelling member 5. Specifically, this end is the first heat sink group 62 below; the seat body 6 is mainly used to fix the light source 7, the wind guide member 4 and the wind expelling member 5, so that the heat dissipation structure is more compact.

[0031] As attached Figure 6As shown, the seat body 6 includes a base plate 61 fixedly connected to the fixed plate 1 and completely shielded by the mounting hole 11, and a first heat sink group 62 fixedly arranged at one end of the base plate 61. The fixed plate 1 and the base plate 61 are sealed and connected by a sealing ring to play a sealing and isolation role to prevent air mixing on both sides; the first heat sink group 62 is formed by a plurality of first heat sinks distributed in a ring shape, and the middle part of the first heat sink group 62 protrudes upward to form a protrusion 621, and the protrusion 621 is formed by the end of each first heat sink close to the center protruding upward, and the air guide member 4 is penetrated by a through opening 43 along its axial direction, and the air guide member 4 is adapted to the protrusion 621 through the through opening 43. Specifically, the through opening 43 is also in the shape of a trumpet with "one end small and the other end large", and the through opening 43 with the smallest diameter is adapted to the protrusion 621.

[0032] As attached Figure 7 As shown, a second heat sink group 63 is fixedly provided at the other end of the substrate 61. The second heat sink group 63 is composed of a plurality of second heat sinks arranged in parallel at intervals. The second heat sink group 63 is provided with a receiving space 630. The light source 7 is fixedly provided on the substrate 61 and is located in the receiving space 630 so that the light source 7 can be installed and fixed.

[0033] In this embodiment, the wind-repelling member 5 can also drive the cold air flow to enter from the opening 43 and flow to the channel formed between adjacent first heat sinks. The cold air exchanges heat with the first heat sink. The air after heat exchange diffuses through the channel to the surrounding heat sink fins, thereby accelerating the heat dissipation efficiency of the heat source.

[0034] As attached Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, a avoidance notch 45 is relatively arranged on the top of the wind guide member 4, a fixing column 64 is relatively arranged on the seat body 6, and the wind deflector 5 is provided with a cross beam 51. After the cross beam 51 crosses through the avoidance notch 45, its two ends are respectively fixedly connected with the fixing column 64, so as to facilitate the quick installation and fixation of the wind deflector 5.

The wind blown out of the air outlet of the blower sweeps the light source and takes away the heat of the light source, the wind with heat reaches the diffusion fan, the diffusion fan rotates and diffuses the wind with heat to the first fin group, so as to achieve the effect of cooling the light source, thereby ensuring the normal operation of the light source, reducing the risk of burning of the light source due to overheating, and thus extending the service life of the light source.

[0037] As attached Figure 1 and attached Figure 2 As shown, the wind driving member 5 is a frameless fan, so that the wind driving member 5 can achieve the maximum driving air volume within a limited installation space, further improving the heat dissipation efficiency of the heat dissipation structure.
