Description

A heat dissipation module and display device Technical Field

[0001] This utility model relates to the field of outdoor display technology, and in particular to a heat dissipation module and display device. Background Technology

[0002] Outdoor LED displays are electronic devices specifically designed to display information in outdoor environments. They are typically installed in public areas, commercial zones, or event venues to provide advertising, information displays, or other visual content. Heat dissipation modules are installed inside the mounting brackets of outdoor LED displays to facilitate heat dissipation from the screen.

[0003] After prolonged use, issues such as fan motor damage, fan blade deformation, or blockage by foreign objects can prevent the fan from blowing cool air onto the display screen, leading to localized overheating and affecting display quality. Therefore, a cooling module and display device are needed to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a heat dissipation module and a display device to solve the problem mentioned in the background art, where after long-term use, the fan motor of the heat dissipation module is damaged, the fan blades are deformed, or they are blocked by foreign objects, which prevents the fan from blowing cool air to the display screen, causing the display screen to overheat in some areas and thus affecting the display effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a heat dissipation module, comprising:

[0007] A heat dissipation assembly includes a U-shaped support rod, a cooling plate, heat dissipation fins, and a fan. The cooling plate is fixed to the side of the U-shaped support rod, the heat dissipation fins are fixed to the side of the cooling plate, and the fan is fixed to the side of the heat dissipation fins.

[0008] The warning assembly includes a support plate, a temperature sensor, a control cabinet, and a signal antenna. The support plate is located in front of the fan, the temperature sensor is fixed to the side of the support plate, and the signal antenna is fixed to the top of the control cabinet.

[0009] Furthermore, the warning component also includes a control board, which is fixed inside the control cabinet, and the temperature sensor is connected to the control board via a signal line.

[0010] Furthermore, the warning assembly also includes a transparent observation door, an indicator light, and an alarm. The transparent observation door is hinged to the side of the control cabinet, the indicator light is fixed to the side of the control panel, and the alarm is fixed to the top of the control cabinet.

[0011] Furthermore, the indicator lights are evenly arranged on the control panel, and their number is consistent with that of the temperature sensors.

[0012] A display device includes a frame, an LED display cover plate, and a heat dissipation module, wherein the LED display is fixed to the side of the frame, and the cover plate is fixed to both sides and the top of the frame.

[0013] Furthermore, it also includes a ventilation assembly, which includes an opening, an electric push rod, and a protective cover. The opening is located in the middle of the upper sealing plate, the lower end of the electric push rod is fixed to the upper end of the uppermost U-shaped support rod, and the protective cover is fixed to the top of the electric push rod.

[0014] Furthermore, the ventilation assembly also includes a waterproof platform, with the upper end of the sealing plate at the upper end of the waterproof platform located outside the opening, and the inner dimension of the protective cover being larger than the outer dimension of the waterproof platform.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through the setting of an alarm component, when a fan at a certain location behind the LED display screen fails to work, the temperature sensor at the corresponding position on the support plate senses the temperature rise of the display screen at that location and transmits it to the control board in the control cabinet via a signal line. The control board then transmits the signal to the back-end via a signal antenna. Upon receiving the alarm, the indicator light corresponding to the temperature sensor at that location turns red, and the alarm sounds. Staff can promptly inspect and repair the heat dissipation components. This setting can provide early warning of the heat dissipation function of the LED display screen, avoiding damage to the LED display screen due to poor heat dissipation.

[0017] II. In this utility model, the ventilation component is designed so that when the LED display screen is working, the electric push rod is activated, which drives the protective cover to rise, exposing the opening on the inside of the waterproof platform. This design can increase the ventilation effect inside the frame when the LED display screen is working. Attached Figure Description

The transparent observation door 33 is hinged to the side of the control cabinet 32, the indicator light 35 is fixed to the side of the control board 34, and the alarm 37 is fixed to the top of the control cabinet 32.

[0036] Indicator lights 35 are evenly arranged on the control board 34, and their number is the same as that of temperature sensors 31;

[0037] The support plate 30 provides support, the temperature sensor 31 (model PT100) monitors the temperature, the control cabinet 32 ​​provides support and protection, the transparent observation door 33 provides a closed function to facilitate observation of the indicator light 35 on the internal control board 34, the control board 34 is used to receive, process and transmit signals, the indicator light 35 displays a green light when the temperature is normal, and displays a red light when the temperature exceeds the set value and receives the signal transmitted by the temperature sensor 31, the signal antenna 36 is used to transmit signals, and the alarm 37 can issue an alarm.

[0038] Working principle:

[0039] When a fan 13 at a certain location behind the LED display screen 21 fails to work, the temperature sensor 31 at the corresponding position on the support plate 30 senses the increase in the display screen temperature and transmits it to the control board 34 in the control cabinet 32 ​​via a signal line. The control board 34 transmits the signal to the back-end via the signal antenna 36. Upon receiving the notification, the indicator light 35 corresponding to the temperature sensor 31 turns red, and the alarm 37 sounds an alarm, allowing staff to promptly inspect and repair the heat dissipation components.

[0040] This step can provide an early warning of the heat dissipation function of the LED display screen 21, and prevent the LED display screen 21 from being damaged due to poor heat dissipation.

[0041] Please refer to Figure 3. This embodiment is a display device, including: a frame 20, an LED display screen 21, a sealing plate 22, and the above-mentioned heat dissipation module.

[0045] Working principle:

[0046] When the LED display screen 21 is working, the electric push rod 42 is activated, causing the protective cover 43 to rise, exposing the opening 40 on the inside of the waterproof platform 41. When the LED display screen 21 is not working, the movable end of the electric push rod 42 retracts, causing the protective cover 43 to move down and cover the waterproof platform 41.

[0047] This step can increase the ventilation effect inside the frame 20 when the LED display 21 is working.
