Abstract
Description
Technical Field
[0001] The utility model relates to an HDMI extender, in particular to an HDMI extender with optimized heat dissipation, and belongs to the technical field of HDMI extenders. Background Art
[0002] An HDMI extender is a highly effective solution for long-distance HDMI signal transmission. It consists of a transmitter and receiver connected via a network cable or optical fiber, ensuring that audio and video signals are transmitted without distortion or degradation over long distances. Whether in conference rooms, surveillance centers, or large-screen outdoor advertising, an HDMI extender provides stable and reliable signal transmission, meeting the needs of diverse applications.
[0003] During use, the internal temperature of an HDMI extender will continue to rise, affecting its performance and service life. Conventional natural cooling cannot effectively meet the heat dissipation requirements of the HDMI extender, resulting in excessively high internal temperature when the HDMI extender works for a long time. Therefore, an HDMI extender with optimized heat dissipation is proposed. Utility Model Content
[0004] In view of this, the present invention provides an HDMI extender with optimized heat dissipation to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.
[0005] The technical solution of the embodiment of the utility model is achieved as follows: a heat dissipation optimized HDMI extender includes a housing assembly, the housing assembly includes a protective shell, a heat dissipation fan, a temperature sensor, a controller, threaded holes, a dust screen and heat dissipation holes;
[0006] Cooling fans are symmetrically mounted on both sides of the protective shell. A temperature sensor and a controller are mounted on the inner sidewall of the protective shell. A signal output terminal of the temperature sensor is connected to a signal input terminal of the controller. Four threaded holes are symmetrically formed on the lower surface of the protective shell. A dust screen is detachably and fixedly mounted on the upper surface of the protective shell. Heat dissipation holes are evenly formed on the inner sidewall of the protective shell. The dust screen is positioned on top of the heat dissipation holes. During operation, the temperature of the circuit components within the HDMI extender continuously rises. Heat from the components is absorbed by the heat conducting plate and dissipated into the interior of the HDMI extender through the heat dissipation fins. When the temperature sensor detects that the internal temperature of the HDMI extender exceeds a preset threshold, it sends a signal to the controller, which controls the cooling fan to operate, driving external air to pass through the dust screen, filter, enter the interior of the HDMI extender through the heat dissipation holes, and transfer the heat to the outside of the extender.
[0007] A base plate assembly is provided at the bottom of the housing assembly.
[0008] Further preferably: the base plate assembly includes a heat dissipation base plate and fixing bolts;
[0009] The heat dissipation base plate is fixedly connected to the protective shell through fixing bolts, and the fixing bolts are threadedly connected to the inside of the threaded holes.

[0017] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:
[0018] 1. This utility model uses a temperature sensor to detect the internal temperature of the HDMI extender. When the internal temperature of the HDMI extender exceeds a preset threshold, a signal is sent to the controller, which controls the fan to operate, thereby improving the heat dissipation effect of the HDMI extender, thereby preventing the internal temperature of the HDMI extender from being too high, extending the service life of the HDMI extender, and improving the performance of the HDMI extender.

[0030] Cooling fans 12 are symmetrically mounted on both sides of the protective housing 11. A temperature sensor 17 and a controller 18 are mounted on the inner wall of the protective housing 11. The signal output of the temperature sensor 17 is connected to the signal input of the controller 18. Four threaded holes 19 are symmetrically formed on the lower surface of the protective housing 11. A dust screen 110 is detachably and fixedly attached to the upper surface of the protective housing 11. Heat dissipation holes 111 are evenly distributed on the inner wall of the protective housing 11. The dust screen 110 is positioned on top of the heat dissipation holes 111. During operation, the temperature of the circuit components within the HDMI extender continuously rises. Heat from the components is absorbed by the heat conducting plate 24 and dissipated into the interior of the HDMI extender through the heat dissipation fins 25. When the temperature sensor 17 detects that the internal temperature of the HDMI extender exceeds a preset threshold, it sends a signal to the controller 18. The controller 18 activates the cooling fan 12, driving external air through the dust screen 110, filtered, and then into the interior of the HDMI extender through the heat dissipation holes 111, transferring the heat to the exterior of the extender.

[0032] In this embodiment, specifically: the base plate assembly 20 includes a heat dissipation base plate 21 and fixing bolts 22;
[0033] The heat dissipation base plate 21 is fixedly connected to the protective shell 11 by fixing bolts 22. The fixing bolts 22 are threadedly connected to the inside of the threaded hole 19. The heat dissipation base plate 21 and the protective shell 11 are fixed by the fixing bolts 22, which facilitates the disassembly and maintenance of the HDMI extender.
[0034] In this embodiment, specifically: a PCB board 23 is mounted on the upper surface of the heat dissipation base plate 21 , and the PCB board 23 supplies power to the internal circuit components of the HDMI extender.

The heat conducting plate 24 and the heat dissipation fins 25 are used to dissipate heat from the internal chip and other heating components of the HDMI extender, thereby improving heat dissipation efficiency.
[0036] In this embodiment, specifically, the heat dissipating fins 25 are disposed below the heat dissipating holes 111 , and after the external low-temperature air enters the protective shell 11 through the heat dissipating holes 111 , it absorbs the heat dissipated by the heat dissipating fins 25 .
[0037] In this embodiment, specifically: the housing assembly 10 further includes a power port 13 and a reset button 14;
