The present embodiment provides a heat dissipation mechanism, which includes a heat pipe module 100 and a heat dissipation module 200, wherein the heat pipe module 100 is disposed near a heat source for absorbing heat, the heat pipe module 100 is disposed on the heat dissipation module 200, and the heat on the heat pipe module 100 is conducted to the heat dissipation module 200 and dissipated through the heat dissipation module 200.

The heat source in this example is a lamp, and may be any type of heat source such as stage lamps, LED lamps, advertisement lamps, and the like. Because the light-emitting area of the lamp is small, but the heat generated in unit area is high, obvious high temperature can be generated, and the heat dissipation power requirement on the heat dissipation mechanism is higher.

As shown in fig. 1 to 3, in the embodiment, the heat pipe module 100 includes a first heat pipe 110 and a second heat pipe 120, the first heat pipe 110 and the second heat pipe 120 are in a U-shaped structure, the first heat pipe 110 and the second heat pipe 120 are respectively in two groups, the openings 130 of the two groups of the first heat pipe 110 and the second heat pipe 120 are oppositely arranged, the size of the opening 130 of the first heat pipe 110 is larger than the size of the opening 130 of the second heat pipe 120 along the first direction, so that the second heat pipe 120 is arranged in the first heat pipe 110, the first heat pipe 110 includes a first heat absorbing portion 111 and two first heat conducting portions 112, the two first heat conducting portions 112 are respectively arranged at two sides of the first heat absorbing portion 111, the second heat pipe 120 includes a second heat absorbing portion 121 and two second heat conducting portions 122, the two second heat conducting portions 122 are respectively arranged at two sides of the second heat absorbing portion 121, the adjacent first heat absorbing portion 111 and the second heat absorbing portion 121 and the adjacent two first heat absorbing portions 111 are mutually contacted and arranged, the first heat absorbing portion 111 and the second heat absorbing portion 121 are simultaneously near the first heat absorbing portion and the second heat source 121, thereby the heat absorbing efficiency is increased.

Compared with the U-shaped heat pipe which is arranged in an opposite-inserting mode in the prior art, the heat radiation mechanism has the advantages that the contact area between the heat pipe module 100 and the stage lamp is increased, heat can be quickly absorbed from the most concentrated position of the heat of the stage lamp, and the heat radiation effect is guaranteed.

The embodiment also provides a lamp, which comprises the illuminating piece and the heat dissipation mechanism, wherein the illuminating piece is arranged on the heat dissipation mechanism, and the illuminating piece is a heating piece. The lamp can realize self heat dissipation, and is favorable for guaranteeing the service life of the lighting part.

Specifically, since the size of the opening 130 of the first heat pipe 110 is larger than the size of the opening 130 of the second heat pipe 120 in the present embodiment, in order to enable the first heat absorbing portion 111 and the second heat absorbing portion 121 to be disposed in contact, the order of mounting the two sets of first heat absorbing portions 111 and the two sets of second heat absorbing portions 121 along the first direction is as follows: the second heat absorbing portion 121, the first heat absorbing portion 111, and the second heat absorbing portion 121.

Further, the cross-sectional shapes of the first heat absorbing portion 111 and the second heat absorbing portion 121 are square. At this time, the contact area between the second heat absorbing portion 121, the first heat absorbing portion 111 and the second heat absorbing portion 121, which are in contact with each other, is increased, and since the heat of the stage lamp is gradually weakened from inside to outside, the heat at different positions is not uniform, in this embodiment, by increasing the contact area between the two adjacent first heat absorbing portions 111 and the second heat absorbing portion 121, the heat conduction between the two adjacent first heat absorbing portions 111 and the second heat absorbing portion 121 or between the two first heat absorbing portions 111 can be performed, which is favorable for balancing the heat, so as to ensure the rapid conduction and heat dissipation of the heat. Specifically, the two first heat absorbing portions 111 and the second heat absorbing portion 121 located in the middle are close to the center of the stage lamp, the heat quantity at the corresponding positions is higher, and in the working process of the heat dissipation mechanism, the first heat absorbing portion 111 can conduct the heat quantity to the second heat absorbing portion 121 in contact with the first heat absorbing portion, so that heat balance is achieved, and the heat conduction power is improved.

For example, the light source light emitting surface of the stage lamp is small, the diameter range of 8 mm will generate heat exceeding 200W, the light emitting surface of 8 mm can only correspond to two first heat absorbing portions 111 or two second heat absorbing portions 121, in this embodiment, two first heat absorbing portions 111 corresponding to the heat source, and the side surfaces of the two first heat absorbing portions 111 need to be conducted to the two second heat absorbing portions 121 at the periphery, so that the heat of the light source can be taken away by the power of the heat pipe module 100.

The cross-sectional shapes of the first and second heat conductive portions 112 and 122 may be circular or square, which is not limited in this embodiment.

The heat dissipation mechanism further comprises a heat dissipation module 200, a first accommodating groove 211 is formed in the heat dissipation module 200, and the heat pipe module 100 is at least partially located in the first accommodating groove 211, so that the heat conduction distance of the heat pipe module 100 is reduced, and the heat dissipation efficiency is improved.

The bottom plate 300 is provided with the second accommodating groove 310, part of the heat pipe module 100 is in the second accommodating groove 310, and the bottom plate 300 is abutted against the heat radiation module 200, so that the distance between the heat pipe module 100 and the lamp is shortened, quick heat taking is facilitated, and the heat absorption effect is improved. At this time, the heat pipe module 100 is partially located on the bottom plate 300 and partially located on the heat dissipation module 200, so that the bottom plate 300 and the heat dissipation module 200 are abutted to each other, so that the heat pipe module 100 contacts the heat dissipation module 200 as many areas as possible, which is beneficial to improving the heat conduction effect.

Meanwhile, the radiating fins of the traditional radiator of part of the existing stage lamps adopt punched aluminum flakes, holes are formed in the aluminum flakes, the heights of the holes are limited, the contact area of the heat pipe is limited, the heat conduction power is influenced, the contact area of the heat pipe and the radiating fins is small, and the radiating efficiency is low. In this embodiment, the heat pipes are disposed on the heat dissipation assembly, so that the heat pipe modules 100 can contact the heat dissipation module 200 in a larger area, and the heat conduction and heat dissipation effects are improved by increasing the contact surface.

The bottom plate 300 and the heat radiation module 200 and/or the bottom plate 300 and the heat pipe module 100 are/is fixed by solder paste, so that the heat pipe module 100 and the bottom plate 300 or the heat radiation module 200 are fixed, separation is avoided when the lamp vibrates at high frequency, and meanwhile, the solder paste has a good heat conduction effect, so that heat conduction between the heat pipe module 100 and the bottom plate 300 and heat radiation module 200 is guaranteed.
