[0051] The embodiments of the first aspect of the present application propose a lamp heat sink for dissipating heat from a light source module. Please refer to Figure 1 and Figure 2 The lamp heat sink 10 includes a heat dissipation module 11, a heat dissipation fan 12 and a mounting seat 13.
[0052] Please refer to Figure 4 and Figure 5 The heat dissipation module 11 includes a center body 111 and a first fin group 112 arranged on the center body 111, the first fin group 112 includes a plurality of first heat dissipation fins 1121 arranged along the circumference of the center body 111, and adjacent two first heat dissipation fins 1121 form a first heat dissipation channel 1122 extending through the center body 111 in the axial direction.
[0053] The center body 111 supports the first fin group 112. The center body 111 can be made of a heat-conductive material or a non-heat-conductive material. When the center body 111 is made of a heat-conductive material, the center body 111 also evenly heats the first fin group 112, so that the heat at different positions of the first fin group 112 is less different, which is beneficial to the wind to take out the heat.
[0054] The first fin group 112 has a ring structure. A plurality of first heat dissipation fins 1121 are fixed on the outer wall surface of the center body 111. For example, the first heat dissipation fins 1121 can be fixed on the outer wall surface of the center body 111 by welding, fastening, clamping or the like. The first heat dissipation fins 1121 are made of a heat-conductive material, which can be a metal material such as aluminum or copper.
[0055] Optionally, the plurality of first heat dissipation fins 1121 are uniformly and spacedly arranged along the circumference of the center body 111, i.e., the plurality of first heat dissipation channels 1122 have the same size, which is beneficial to uniform heat dissipation.
[0056] Optionally, in the radial direction of the center body 111, the width of the first heat dissipation channel 1122 gradually increases from the inside to the outside.
[0057] Please refer to Figure 2 to Figure 4 The heat dissipation fan 12 is connected to the heat dissipation module 11 at one end of the center body 111 in the axial direction, and is used to send air into the first heat dissipation channel 1122.
[0058] Optionally, the central axis of the heat dissipation fan 12 corresponds to the center body 111 of the heat dissipation module 11, and the blades of the heat dissipation fan 12 correspond to the first fin group 112 of the heat dissipation module 11.
[0059] Since the heat dissipation fan 12 is connected to the heat dissipation module 11 at one end of the center body 111 in the axial direction, and the first heat dissipation channel 1122 extends along the axial direction of the center body 111, when the heat dissipation fan 12 works, the air enters the first heat dissipation channel 1122 from one end of the first heat dissipation channel 1122, and flows out from the other end of the first heat dissipation channel 1122, so as to take away the heat on the first heat dissipation fins 1121.
[0060] Please refer to Figure 1 and Figure 2 The mounting seat 13 is connected to the heat dissipation module 11 at the outer circumferential side of the center body 111 in the radial direction, and is used to mount the light source module 20.
[0061] Optionally, the light source module 20 is mounted on the side surface of the mounting seat 13 away from the heat dissipation module 11. The side surface of the mounting seat 13 away from the heat dissipation module 11 can be a rectangular side surface, a circular side surface or other shaped side surface.
[0062] After the light source module 20 is installed on the mounting seat 13, heat generated by the light source module 20 during operation is conducted to the heat dissipation module 11 via the mounting seat 13, and the heat dissipation fan 12 is used to blow away the heat of the heat dissipation module 11, so as to achieve heat dissipation of the light source module 20.
[0063] The mounting seat 13 is made of a heat-conducting material, which is optionally a metal material, such as aluminum, copper, or the like.
[0064] The lamp radiator 10 provided by the embodiment has the following beneficial effects: the plurality of first heat dissipation fins 1121 are arranged along the circumference of the central body 111, and the two adjacent first heat dissipation fins 1121 form a first heat dissipation channel 1122 extending through the central body 111 in the axial direction, so that the plurality of first heat dissipation channels 1122 are arranged along the circumference of the central body 111; in this way, the arrangement direction of the plurality of first heat dissipation channels 1122 is close to the wind flow direction, which is beneficial to solve the problem of wind flow disorder at the air inlet of the heat dissipation fins, reduce wind resistance, and improve wind flow to meet the heat dissipation requirement, while reducing the noise generated by wind cutting.
[0065] Moreover, the heat dissipation fan 12 is connected to the heat dissipation module 11 at one end of the central body 111 in the axial direction, and the mounting seat 13 is connected to the heat dissipation module 11 at the outer circumferential side of the central body 111 in the radial direction; in this way, when the heat dissipation fan 12 sends air into the first heat dissipation channel 1122, the mounting seat 13 will not block the first heat dissipation channel 1122, which is beneficial to the outflow of air from the first heat dissipation channel 1122, thereby improving the heat dissipation efficiency.
[0066] Please refer to Figure 2 to Figure 4 In some embodiments, the lamp radiator 10 further comprises a heat pipe 114 extending along the circumference of the central body 111, and the heat pipe 114 is arranged on the first fin group 112 and in contact with the mounting seat 13.
[0067] It can be understood that the heat pipe 114 can extend along the circumference of the central body 111 for one turn, that is, the heat pipe 114 is a ring-shaped heat pipe; or the heat pipe 114 comprises two pipe segments, each pipe segment extending along the circumference of the central body 111 for half a turn, and the two pipe segments are spliced for one turn.
[0068] By arranging the heat pipe 114 on the first fin group 112, the heat pipe 114 can conduct the heat of the mounting seat 13, which is beneficial to quickly and uniformly conducting the heat on the mounting seat 13 to the first fin group 112, thereby improving the heat dissipation efficiency, and is particularly suitable for heat dissipation of the high-power light source module 20.
[0069] In other embodiments, for the low-power light source module 20, the heat pipe 114 can not be arranged on the first fin group 112, and only the first fin group 112 is used for heat dissipation, which can meet the heat dissipation requirement.
[0070] Please refer to Figure 3 to Figure 5 In some embodiments, the heat dissipation module 11 further comprises a second fin group 113 arranged on the first fin group 112, the second fin group 113 comprises a plurality of second heat dissipation fins 1131 arranged at intervals along the circumference of the center body 111, and adjacent two second heat dissipation fins 1131 form a second heat dissipation channel 1132 extending through the center body 111 in the axial direction.
[0071] The first fin group 112 supports the second fin group 113; wherein the second fin group 113 is in the form of a ring structure.
[0072] The plurality of second heat dissipation fins 1131 are respectively fixed on the first heat dissipation fins 1121, for example, the second heat dissipation fins 1131 can be fixed on the first heat dissipation fins 1121 by welding, fastener connection, clamping, etc. Wherein the second heat dissipation fins 1131 are made of heat-conducting material, which can be metal material, such as aluminum, copper, etc.
[0073] Optionally, the plurality of second heat dissipation fins 1131 are arranged at uniform intervals along the circumference of the center body 111, that is, the plurality of second heat dissipation channels 1132 are of the same size, which is conducive to uniform heat dissipation.
[0074] Optionally, in the radial direction of the center body 111, the width of the second heat dissipation channel 1132 gradually increases from inside to outside.
[0075] Please refer to Figure 2 and Figure 3 The heat pipe 114 is between the first fin group 112 and the second fin group 113, and the second fin group 113 is provided with a first notch 115 corresponding to the position of the mounting seat 13 for exposing the heat pipe 114.
[0076] Optionally, the heat pipe 114 is wound on the first fin group 112 and covered by the second fin group 113. Wherein the first fin group 112 and the second fin group 113 are arranged corresponding to the blades of the heat dissipation fan 12.
[0077] By providing the first notch 115 on the second fin group 113, the heat pipe 114 is exposed, thereby realizing the contact between the heat pipe 114 and the mounting seat 13. Wherein the size of the first notch 115 can be set according to the size of the mounting seat 13.
[0078] By arranging the second fin group 113 on the first fin group 112, the heat dissipation area can be increased, and the heat dissipation efficiency can be further improved; and by arranging the heat pipe 114 between the first fin group 112 and the second fin group 113, the heat on the first fin group 112 and the second fin group 113 can be balanced, and the arrangement of the heat pipe 114 is facilitated.
[0079] Please refer toFigure 3 and Figure 4 In some embodiments, the first heat dissipation fin 1121 comprises a first heat dissipation body 11211 and a first folded edge 11212, and the first heat dissipation body 11211 is provided with the first folded edge 11212 at at least one end in the radial direction of the center body 111.

It can be understood that the inner end and the outer end of the first heat dissipation body 11211 are both provided with the first folded edge 11212 in the radial direction of the center body 111, or only the inner end of the first heat dissipation body 11211 is provided with the first folded edge 11212, or only the outer end of the first heat dissipation body 11211 is provided with the first folded edge 11212.
[0082] When the inner end and the outer end of the first heat dissipation body 11211 are both provided with the first folded edge 11212, the first folded edge 11212 of the inner end of the first heat dissipation body 11211 is smaller than the first folded edge 11212 of the outer end of the first heat dissipation body 11211, so that the width of the first heat dissipation channel 1122 gradually increases from inside to outside. Among them,

[0088] The second heat dissipation body 11311 is provided with the second folded edge 11312 at at least one end in the radial direction of the center body 111, which can be understood as that the inner end and the outer end of the second heat dissipation body 11311 are both provided with the second folded edge 11312 in the radial direction of the center body 111, or only the inner end of the second heat dissipation body 11311 is provided with the second folded edge 11312, or only the outer end of the second heat dissipation body 11311 is provided with the second folded edge 11312.
[0089] When the inner end and the outer end of the second heat dissipation body 11311 are both provided with the second folded edge 11312, the second folded edge 11312 of the inner end of the second heat dissipation body 11311 is smaller than the second folded edge 11312 of the outer end of the second heat dissipation body 11311, so that the width of the second heat dissipation channel 1132 gradually increases from the inside to the outside. Among them, the two second folded edges 11312 of the inner end and the outer end of the second heat dissipation body 11311 can be folded towards the same side of the second heat dissipation body 11311, at this time, the second heat dissipation fin 1131 is U-shaped as a whole; the two second folded edges 11312 of the inner end and the outer end of the second heat dissipation body 11311 can also be folded towards different sides of the second heat dissipation body 11311, at this time, the second heat dissipation fin 1131 is Z-shaped as a whole.
[0090] Among them, the second folded edge 11312 provided at the inner end of the second heat dissipation body 11311 can increase the contact area of the second heat dissipation fin 1131 and the heat pipe 114, which is conducive to the stability of the connection between the second heat dissipation fin 1131 and the heat pipe 114; the second folded edge 11312 provided at the outer end of the second heat dissipation body 11311 makes the wind flow only in the axial direction of the center body 111 in the second heat dissipation channel 1132, which can improve the utilization rate of the wind and further improve the heat dissipation efficiency.
