Description

Technical Field

[0001] The utility model relates to the field of stage lights, in particular to a heat dissipation module for stage lights. Background Art

[0002] In the prior art, a plurality of parallel and spaced heat dissipation fins are provided at the bottom of the mounting plane of the stage light radiator, and a heat dissipation fan is installed at the bottom of the heat dissipation fins to achieve heat dissipation. For example, the radiator disclosed in patent publication number CN221648411U has a plurality of parallel and densely arranged heat dissipation fins at the bottom of the mounting plate. This arrangement of heat dissipation fins is a relatively typical structure. Although this structure can maximize the contact area between the heat dissipation fins and the air, the air ducts between adjacent heat dissipation fins are not connected to each other. When the wind from the heat dissipation fan blows towards the heat dissipation fins, the fast-flowing airflow cannot be distributed throughout the entire radiator, resulting in uneven heat dissipation effect. The heat dissipation effect in the middle is significantly stronger than that at the edges and corners. In addition, since the bottoms of the heat dissipation fins are all located on the same plane, the heat dissipation fan will take up extra space when installed, which is not conducive to optimal use of space.

[0024] For example, please refer to Figure 1-4 As shown:

[0025] A stage light heat dissipation module includes a heat dissipation base 100; the heat dissipation base 100 includes a connecting plate 110 and a plurality of heat dissipation fins 120 arranged at intervals at the bottom of the connecting plate 110; the connecting plate 110 is generally flat, the upper surface is a mounting surface, and the lower surface is used to mount the heat dissipation fins 120. When the mounting surface provides a complete flat surface, it can ensure better contact with the heat generating part, ensure rapid heat transfer, and facilitate installation; in one embodiment, the top of the connecting plate 110 is provided with a plurality of first grooves 111, and the first grooves 111 can be used to mount a lifting motor and the like to provide an accommodation space for them; in one embodiment, a sealing ring mounting groove 112 is provided on the circumference of the connecting plate 110, and a sealing ring is disposed in the sealing ring mounting groove 112. The sealing ring mounting groove 112 can limit the position of the sealing ring and improve the sealing effect;

[0026] A main air duct 130 is formed in the middle of the bottom of the connecting plate 110; the heat dissipation fins 120 are arranged on both sides of the main air duct 130; a first air duct 123 is formed between two adjacent heat dissipation fins 120; the first air duct 123 is connected to the main air duct 130; the extension direction of the main air duct 130 is preferably consistent with the length direction of the connecting plate 110, so that the length of the heat dissipation fins 120 on both sides of the main air duct 130 can be shortened, and the length of the first air duct 123 is shortened. Figure 4 As shown, the length of the heat dissipation fin 120 is Figure 4 The left-right dimensions in the figure enable the air blown by the cooling fan 200 to pass through the first air duct 123 more quickly, thereby improving the heat dissipation effect. At the same time, the connecting structure of the main air duct 130 and the first air duct 123 enables the first air ducts 123 between the heat dissipation fins 120 to be connected. The air blown by the cooling fan 200 can cover the entire bottom of the connecting plate 110 as much as possible, reducing the existence of blind spots and effectively improving the heat dissipation uniformity.

[0027] In one embodiment, the heat dissipation fin 120 includes a first heat dissipation portion 121 and a second heat dissipation portion 122; the first heat dissipation portion 121 is arranged near the edge of the connecting plate 110; the second heat dissipation portion 122 is arranged near the main air duct 130; the height of the second heat dissipation portion 122 is less than the height of the first heat dissipation portion 121 to form a fan mounting slot; by lowering the height of the second heat dissipation portion 122 to form an installation space for accommodating the heat dissipation fan 200, the space of the radiator can be effectively utilized and the occupation of the external space can be reduced. Although lowering the height of the second heat dissipation portion 122 will reduce the contact area between the heat dissipation fin 120 and the air, due to the main air duct 1 The connecting structure between the second heat dissipation portion 122 and the first air duct 123 improves the fluidity of the air flow, increases the heat exchange rate, and ensures that the radiator has a good heat dissipation effect. At the same time, since the second heat dissipation portion 122 is closest to the heat dissipation fan 200, the wind blown by the heat dissipation fan 200 has the highest wind speed at the second heat dissipation portion 122, and the wind speed at the first heat dissipation portion 121 decreases. The higher the wind speed, the better the heat dissipation effect. Correspondingly, reducing the height of the second heat dissipation portion 122 can ensure that the heat dissipation effects of the first heat dissipation portion 121 and the second heat dissipation portion 122 are closer, thereby achieving consistent heat dissipation at all locations of the heat dissipation fins 120.

[0028] In one embodiment, a cooling fan 200 is fixedly connected to the fan mounting slot; multiple cooling fans 200 are provided and fixedly connected to the fan mounting slot via a fan bracket 210; the cooling fan 200 is arranged opposite the main air duct 130; three cooling fans 200 are provided and arranged in sequence along the length direction of the main air duct 130, covering the main air duct 130 as much as possible to ensure efficient heat dissipation; a fan protection cover 220 is provided on the outside of the cooling fan 200 and fixedly connected to the heat dissipation fins 120 to prevent debris from entering the cooling fan 200 and improve safety;

[0029] In one embodiment, the angle between the first heat dissipation portion 121 and the second heat dissipation portion 122 is α, wherein 120°≤α<180°. In one embodiment, α=150°. A large angle helps guide the wind, and the wind blown by the cooling fan 200 is more easily guided to flow into the first air duct 123. In one embodiment, the second heat dissipation portion 122 is tilted toward the center of the main air duct 130. Figure 4 As shown, the second heat dissipation parts 122 are all inclined toward the center; the inclined setting of the second heat dissipation parts 122 can not only increase the available length, thereby increasing the contact area with the air, but also can be used to guide the wind; in one embodiment, the heat dissipation fan 200 is provided, which is arranged in the middle of the main air duct 130, and can fully utilize the guide structure formed by the second heat dissipation part 122 inclined toward the center of the main air duct 130 to maximize the air outlet utilization of the heat dissipation fan 200.
