Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and specifically relates to a novel display screen fan heat dissipation structure. Background Art

[0002] The current development trend of vehicle-mounted displays is towards larger screens and higher brightness. In addition, vehicles are easily exposed to direct sunlight. In the summer, due to the high ambient temperature and high display brightness, the display itself generates a lot of heat. After turning on the display, the touch temperature of the display is very high, resulting in a poor user experience.

[0003] The patent number is 201822158140.8, and a public specification published on July 5, 2019 discloses a heat dissipation structure for a vehicle-mounted touch display screen, including a touch display module, a plastic panel, a PCBA board and a hardware bracket connected in sequence, and also includes a first heat conductor and a second heat conductor. The first heat conductor connects the touch display module and the PCBA board, and the second heat conductor connects the PCBA board and the hardware bracket. The utility model sets a first heat conductor to connect the touch display module and the PCBA board, and sets a second heat conductor to connect the PCBA board and the hardware bracket, without increasing the weight and cost of the whole machine, thereby solving the problems of poor heat dissipation and high cost of the existing vehicle-mounted touch display screen.

[0004] There are two main ways to lower the temperature: 1. Turn on the air conditioner in the car to lower the ambient temperature. By lowering the ambient temperature, the surface temperature of the display screen can be indirectly lowered. However, this method is inefficient and takes a long time to lower the surface temperature of the touch screen. 2. Lower the brightness of the display screen to reduce heat generation. This method will affect the visual effect of the display content and easily result in poor screen visibility under direct sunlight. Utility Model Content

[0005] The utility model aims to provide a novel display screen fan heat dissipation structure with good heat dissipation effect.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new display fan heat dissipation structure, including a mounting bracket, the display screen is mounted on the mounting bracket, a fan is arranged between the mounting bracket and the display screen, an air inlet is arranged at one end of the mounting bracket, and an air outlet is arranged at the other end of the mounting bracket, and the mounting bracket and the display screen are tightly fitted.

[0007] A mounting pad is provided between the display screen and the mounting bracket.

[0008] The fan is installed at the air inlet.

[0009] The air outlets are arranged in a row at the end of the mounting bracket.

[0010] The mounting bracket is provided with a PCBA connected to the display screen and the fan signal.

[0011] A closed cavity is formed between the mounting bracket and the display screen.

[0012] The mounting bracket is in a basin shape, and the air outlet is arranged on the side of the mounting bracket.

[0013] The technical effect of the utility model is as follows: a fan blowing toward the display screen is provided on the mounting bracket, and because the fan is arranged at one end of the mounting bracket, the air outlet and the air inlet are respectively arranged at the two ends of the mounting bracket, so that when the fan blows air, the wind will blow from one end of the display screen to the other end, which can completely cover the back of the entire display screen, and better cool the display screen.
