Description

Technical Field

[0001] The utility model relates to the technical field of stage lighting lamps, in particular to a heat dissipation module for a driving power supply of a stage lighting lamp. Background Technique

[0002] The driving power supply of a stage lighting lamp is a crucial component in a stage lighting system. Its functions are mainly reflected in aspects such as power supply, current regulation, and lamp protection. Its structure includes a transformer, a rectification circuit, a current regulation circuit, and a protection circuit. Through collaborative work, it realizes stable power supply to the lamp and provides a protection mechanism. The principle of the driving power supply involves power conversion and control technologies. Through advanced digital technologies, it realizes communication with the control system, thereby achieving fine regulation of the lamp to meet the needs of different stage performances. At present, the driving power supply of stage lighting lamps is mainly installed in a housing, and several heat dissipation ribs on the inner wall of the housing are used for heat conduction to reduce the working heat of the driving power supply and the lamp body. Some stage lighting lamps also add heat dissipation fans to increase air circulation. However, the heat generated by the components contained in these driving power supplies is relatively concentrated, and the layout of the heat dissipation ribs often fails to fully cover the entire circuit board, resulting in poor heat dissipation effect in the high-density area, causing local overheating and affecting the working performance and service life of the electronic components inside the driving power supply. Content of the Utility Model

[0003] The purpose of the utility model is to provide a heat dissipation module for a driving power supply of a stage lighting lamp to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A heat dissipation module for a driving power supply of a stage lighting lamp includes a columnar heat dissipation sleeve and an upper heat dissipation end cover bolted and installed at the top end of the columnar heat dissipation sleeve. A support tube is installed at the central position of the bottom end of the columnar heat dissipation sleeve. A number of vertical ribs are installed on the outer wall of the columnar heat dissipation sleeve. A lower tray and a cross-shaped ventilation disc are respectively fixed at both ends inside the columnar heat dissipation sleeve. A drum fan is installed at the top end of the lower tray. An outer shaft sleeve is fixed at the central position of the bottom end of the upper heat dissipation end cover, and a double-layer air supply fan blade structure is rotatably installed at the bottom end of the outer shaft sleeve.

[0005] Preferably, internal threaded holes are opened at the edge position of the top end of the upper heat dissipation end cover.

[0006] Preferably, a number of equidistant horizontal ribs are annularly distributed at the top end of the upper heat dissipation end cover.

[0007] Preferably, the columnar heat dissipation sleeve and the upper heat dissipation end cover are both made of components of aluminum alloy material, and a number of ventilation holes are arranged on the upper surface of the cross-shaped ventilation disc.

[0008] Preferably, a shaft disc is rotatably installed inside the outer shaft sleeve, and a short shaft is installed at the center position of the bottom end of the shaft disc.

[0009] Preferably, the double-layer air supply fan blade structure includes a plurality of upper guide fan blades fixed on the outer peripheral surface of the short shaft, and a plurality of lower guide fan blades are installed on the outer peripheral surface of the short shaft below the upper guide fan blades.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The heat dissipation module of the driving power supply of the stage lighting lamp positions the driving power supply between the drum fan and the double-layer air supply fan blade structure. The drum fan actively blows a large amount of air to the heat dissipation module, accelerating the conduction and dissipation of heat, making the heat dissipation speed faster. Moreover, the double-layer air supply fan blade structure assists in sending out hot air, and the vertical ribs effectively increase the heat dissipation surface area of the columnar heat dissipation sleeve, improving the heat dissipation efficiency. The upper heat dissipation end cover and the horizontal ribs play an auxiliary heat conduction role at the top of the columnar heat dissipation sleeve, forming a heat channel, enabling heat to be discharged from the inside of the columnar heat dissipation sleeve more quickly and effectively.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4The utility model provides an embodiment: a heat dissipation module of a stage lighting lamp driving power supply, comprising a columnar heat dissipation sleeve 1 and an upper heat dissipation end cover 6 bolted and installed at the top of the columnar heat dissipation sleeve 1, an internal threaded hole is opened at the edge position of the top of the upper heat dissipation end cover 6, the upper heat dissipation end cover 6 is buckled on the top of the columnar heat dissipation sleeve 1 and the two are fixed by bolts;

[0018] A support tube 3 is installed at the center of the bottom end of the columnar heat dissipation sleeve 1, and a plurality of vertical ribs 2 are installed on the outer wall of the columnar heat dissipation sleeve 1. The vertical ribs 2, as a part of the columnar heat dissipation sleeve 1, not only play a role in heat dissipation, but also can enhance the stability of the overall structure. The distribution of the vertical ribs 2 forms a uniform support structure, which improves the vibration resistance and bearing capacity of the columnar heat dissipation sleeve 1.

[0019] A lower tray 4 and a cross-shaped ventilation disk 8 are fixed at both ends of the columnar heat dissipation sleeve 1, and the power box is bolted to the top of the cross-shaped ventilation disk 8. The upper surface of the cross-shaped ventilation disk 8 is provided with a plurality of ventilation holes 801, and the ventilation holes 801 are used for the purpose of air circulation. A blower fan 5 is installed at the top of the lower tray 4, and an outer sleeve 9 is fixed at the center of the bottom end of the upper heat dissipation end cover 6, and a double-layer fan blade structure 10 is rotatably installed at the bottom end of the outer sleeve 9;

[0020] Part of the wind force generated by the blower fan 5 will synchronously drive the double-layer fan blade structure 10 to rotate. The double-layer fan blade structure 10 allows the hot air to flow more evenly inside the heat dissipation module, avoiding local dead corners and improving the flow speed and uniformity of the hot air.

[0021] The columnar heat dissipation sleeve 1 and the upper heat dissipation end cover 6 are both made of aluminum alloy. A plurality of equally spaced horizontal ribs 7 are distributed in a ring shape on the top of the upper heat dissipation end cover 6. The upper heat dissipation end cover 6 and the horizontal ribs 7 play an auxiliary heat conduction role at the top of the columnar heat dissipation sleeve 1.

[0022] A shaft disk 901 is rotatably installed inside the outer shaft sleeve 9, and a short shaft 902 is installed at the center position of the bottom end of the shaft disk 901. The double-layer fan blade structure 10 includes a plurality of upper guide blades 1001 fixed on the outer peripheral surface of the short shaft 902, and a plurality of lower guide blades 1002 are installed on the outer peripheral surface of the short shaft 902 below the upper guide blades 1001. When the blower fan 5 actively blows air, part of the wind force generated in the process covers the double-layer fan blade structure 10, and the upper guide blades 1001 and the lower guide blades 1002 are driven to rotate, thereby effectively taking away heat, avoiding heat retention in local areas, and improving the overall heat dissipation effect of the heat dissipation module.

[0023] When the embodiment of the present application is in use, first, the staff takes out the driving power supply of the stage lighting lamp to be assembled, and installs the power supply box on the top of the cross-shaped ventilation disc 8 in a bolted manner. Subsequently, the upper heat dissipation end cover 6 is taken out, and the upper heat dissipation end cover 6 is buckled on the top of the columnar heat dissipation sleeve 1 and fixed to each other by bolts. At this time, the driving power supply of the stage lighting lamp and the heat dissipation module are assembled together. Then, the assembled accessories are assembled into the housing of the stage lighting lamp. When the stage lighting lamp is working and heat is generated by the housing and the power supply, the driving power supply supplies power to the drum fan 5 synchronously, so that the heat generated by the electrical components in the columnar heat dissipation sleeve 1 is blown by the drum fan 5 to the upper heat dissipation end cover 6. In this process, the ventilation holes 801 serve the purpose of allowing air to circulate. And part of the wind generated by the drum fan 5 will synchronously drive the double-layer air supply fan blade structure 10 to rotate. The double-layer air supply fan blade structure 10 makes the hot air flow more evenly inside the heat dissipation module, avoiding local dead corners, and improving the flow speed and uniformity of the hot air. The heat dissipation module places the driving power supply between the drum fan 5 and the double-layer air supply fan blade structure 10. The drum fan 5 actively blows a large amount of air into the heat dissipation module to accelerate the conduction and dissipation of heat, making the heat dissipation faster. And the double-layer air supply fan blade structure 10 assists in sending out the hot air. The vertical ribs 2 effectively increase the heat dissipation surface area of the columnar heat dissipation sleeve 1, improving the heat dissipation efficiency. The upper heat dissipation end cover 6 and the horizontal ribs 7 play an auxiliary heat conduction role at the top of the columnar heat dissipation sleeve 1, forming a heat channel, so that the heat can be discharged more quickly and effectively from the inside of the columnar heat dissipation sleeve 1.
