Wherein the metal foam body 11 has a first end and a second end opposite to each other, and the metal foam body 11 has a through-going hole passing through the first end and the second end. The metal foam body 11 has good heat dissipation effect because of foam pores.
Illustratively, the metal foam body 11 can be obtained by 3D printing, or by powder metallurgy (adding a foaming agent to the metal powder). Optionally, the metal foam body 11 comprises a metal mono-layer or metal alloy layer, for example, the metal foam body 11 is an aluminum foam body or a copper foam body.
The phase change tube 12 is U-shaped, the phase change tube 12 includes a first tube segment 121, a second tube segment 122 and a third tube segment 123 connected to each other, at least a portion of the first tube segment 121 and the third tube segment 123 is disposed in the through hole and contacts with the hole wall, the light source 13 is disposed on one side of the first end and connected to the second tube segment 122, and the light source 13 is enabled to transfer heat to the second tube segment 122.
Since the light source 13 is connected to the second pipe section 122, heat emitted from the light source 13 can be transferred to the second pipe section 122, and since the first pipe section 121 and the third pipe section 123 are both connected to the second pipe section 122, heat can be transferred from the second pipe section 122 to the first pipe section 121 and the third pipe section 123, and then the heat can be transferred to the metal foam body 11 through the first pipe section 121 and the third pipe section 123 to be dissipated. Since the first pipe section 121 and the third pipe section 123 can transfer heat of the second pipe section 122, the heat dissipation effect is good.
In addition, at least part of the first pipe section 121 and the third pipe section 123 is arranged in the through hole and is in contact with the hole wall, which means that the outer wall of the part of the first pipe section 121 and the part of the third pipe section 123 in the through hole are surrounded by the metal foam body 11, and the first pipe section 121 and the third pipe section 123 are in seamless connection, so that the interface thermal resistance is low, and the heat conduction effect can be improved.
Illustratively, the first pipe segment 121 and the third pipe segment 123 are both straight pipes, and when assembling, the metal foam body 11 is first formed into through holes extending along a straight line, the outer diameters of the first pipe segment 121 and the third pipe segment 123 are respectively the same as the hole diameters of the corresponding through holes, and then the first pipe segment 121 and the third pipe segment 123 are inserted into the corresponding through holes, so that the outer wall of the first pipe segment 121 and the outer wall of the third pipe segment 123 are respectively in contact with the hole walls of the corresponding through holes.
In other embodiments, the first segment 121 and the third segment 123 may be bent pipes, and the foaming agent is added into the metal melt to be sintered together with the phase change pipe 12 in the mold, so as to obtain an integral structure of the metal foam body 11 and the phase change pipe 12.
At least a portion of the first tube segment 121 and the third tube segment 123 is disposed in the through hole and contacts the hole wall, that is, all of the first tube segment 121 and the third tube segment 123 may be disposed in the through hole and contact the hole wall, or a portion of the first tube segment 121 and the third tube segment 123 may be disposed in the through hole and contact the hole wall.
Illustratively, the first tube segment 121 and/or the third tube segment 123 extend through the hole and protrude from the second end of the metal foam body 11. That is, the first pipe segment 121 may extend out of the through hole alone, and the third pipe segment 123 may extend out of the through hole alone, or both the first pipe segment 121 and the third pipe segment 123 may extend out of the through hole.
Since the first tube segment 121 and/or the third tube segment 123 extend out of the through hole, the portion extending out of the through hole can directly transfer heat to the air for heat dissipation.
Illustratively, the first tube segment 121 and/or the third tube segment 123 extend out of the through hole by 1/10-1/3 of the length of the through hole, such as 1/10, 1/9, 1/8, 1/7, 1/6, 1/5, 1/4, or 1/3.
Optionally, the phase change pipe 12 has a plurality of phase change pipes, a first section of two adjacent phase change pipes 12 contacts or connects, a second section of two adjacent phase change pipes 12 contacts or connects, and a third section of two adjacent phase change pipes 12 contacts or connects.
The heat of the light source 13 is transferred to the metal foam body 11 through the phase change tubes to be dissipated, so that the heat dissipation efficiency is higher, and the heat dissipation effect is better. And the first sections of the two adjacent phase change tubes 12 are contacted or connected, the second sections of the two adjacent phase change tubes 12 are contacted or connected, and the third sections of the two adjacent phase change tubes 12 are contacted or connected, so that the phase change tubes 12 and the foam metal body can be more conveniently assembled.
In some embodiments, the second pipe segment is in contact with or connected to the metal foam body 11.
Because the second pipe section contacts or is connected with the metal foam body 11, the second pipe section not only can radiate heat by transferring the heat to the first pipe section 121 and the third pipe section 123, but also can radiate heat by directly transferring the heat to the metal foam body 11 through the first pipe section 121 and the third pipe section 123, and thus the radiating effect can be improved.
Illustratively, the first end of the metal foam body 11 has a recess, and the second tube section is provided in the recess. The second pipe section is provided in the recess of the metal foam body 11, and the phase change pipe 12 can be fixed to the metal foam body 11 more stably.
Further, in some embodiments, the light source 13 is in contact with a first end of the metal foam body 11.
Alternatively, the projection of the light source 13 at the second end of the metal foam body 11 is entirely located on the surface of the metal foam body 11. That is, the entire surface of the light source 13 in contact with or connected to the metal foam body 11 can transfer heat to the metal foam body 11, further improving the heat dissipation effect.
In summary, in the lighting device 10 according to the embodiment of the present application, the heat emitted from the light source 13 can be transferred to the second pipe segment 122, and transferred from the second pipe segment 122 to the first pipe segment 121 and the third pipe segment 123, and then transferred to the metal foam body 11 for heat dissipation, so that the heat dissipation effect is good.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
