Description

Technical Field

[0001] The utility model relates to the technical field of dimming cabinets, and more specifically, to a heat dissipation system for dimming cabinets. Background Art

[0002] Among the various controls of stage lighting, the brightness control of the light is the most basic control. The brightness changes of stage lighting can be attributed to sudden brightness and sudden dimming, gradual brightness and gradual dimming. At present, the control of stage LED lighting is basically adjusted by dimmer cabinets. Dimmer cabinets are mainly used in performance venues. Various electrical components in the dimmer cabinet work together to adjust the LED lights, which can transform the stage into various scenes.

[0003] Nowadays, the control of stage LED lights is basically adjusted by dimmer cabinets. Dimmer cabinets are mainly used in performance venues. Various electrical components in the dimmer cabinets work together to adjust the LED lights, which can transform the stage into various scenes. However, the current dimmer cabinets lack shielding structures, making it difficult to shield signal interference, and the heat dissipation effect is poor.

[0004] After searching, a Chinese patent with publication number CN216566035U discloses a high heat dissipation dimming cabinet that can shield signal interference. The shielding effect of the signal can be enhanced by placing a shielding body in the first slot. When the heat dissipation fan is turned on, the hot air in the cabinet can be blown away from the cabinet through the shielding body from the bottom of the cabinet, thereby improving the heat dissipation effect of the device. When the motor is turned on to drive the roller to rotate, multiple fixed plates can be rotated to achieve large-area fanning, and the hot air in the cabinet can be quickly discharged through the second slot and the third slot.

[0005] When the above-mentioned high-heat dissipation dimming cabinet that can shield signal interference is actually used, the internal electrical components of the dimming cabinet will generate a large amount of heat during long-term operation. The increase in temperature will cause the working efficiency of the electronic components to decrease, which may cause accelerated aging of the components and shorten the service life of the dimming cabinet.

[0044] Reference Figure 2 As shown, two air inlets 17 are provided at both ends of the cabinet 1, and a plurality of hanging ears 18 are fixedly connected to the top of the cabinet 1.

[0046] Working principle of the utility model: The utility model designs a heat dissipation system for dimming cabinets. The specific structure is as shown in the attached manual. Figure 1-6As shown, in the technical solution, through the mutual cooperation between various structures, when the dimming box body 2 generates heat during operation, the refrigeration plate 3 is started first, and the refrigerant in the refrigeration plate 3 is transported to the inside of the thermostat 5 through the first delivery pipe 4, and the temperature of the refrigerant is judged by the inside of the thermostat 5. When the temperature of the refrigerant decreases, the thermostat 5 transports the refrigerant to the inside of the water pump 7 through the second delivery pipe 6, and then the water pump 7 re-transports the refrigerant to the inside of the refrigeration plate 3 through the third delivery pipe 8, so that the refrigeration plate 3 can continue to absorb heat and produce a cooling effect. When the temperature of the refrigerant in the refrigeration plate 3 is high, the refrigerant is transported to the inside of the fourth delivery pipe 24 through the thermostat 5, and the fourth delivery pipe 24 transports the refrigerant to the inside of the heat sink 10 through the input end at the top of the heat sink 10, and then the first cooling fan 11 is started, and the surface temperature of the heat sink 10 is reduced by the first cooling fan 11, and then the heat is quickly dissipated to the outside air through the first heat dissipation window 12, so that The temperature of the refrigerant in the heat sink 10 is lowered, and then the water pump 7 extracts the cooled refrigerant through the extraction pipe 9 and transports it to the inside of the refrigeration plate 3 through the third delivery pipe 8, so that the refrigeration plate 3 can continuously reduce the heat generated by the operation of the dimming box body 2, and at the same time, multiple second cooling fans 23 are started, and the heat on both sides of the dimming box body 2 can be absorbed by two heat-absorbing plates 14. Multiple second cooling fans 23 can dissipate the heat to the outside air through the second heat dissipation window 15, and the air inside the cabinet 1 can be convected with the outside air, so that the temperature inside the cabinet 1 can be kept stable at will. When the dimming box body 2 shakes during operation, the dimming box body 2 will drive the cabinet 1 to shake, so that the cabinet 1 drives the support plate 20 to move up and down. Multiple rubber buffer columns 22 are used to buffer the four corners of the sound-absorbing cotton 21, which can effectively slow down the shaking of the cabinet 1. At the same time, the sound-absorbing cotton 21 can absorb the noise generated by the shaking of the cabinet 1, so that the cabinet 1 can run stably.

In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
