Description
Technical Field
[0001] The utility model relates to the technical field of industrial equipment, in particular to a display screen with a heat dissipation device. Background Art
[0002] A flexible display screen is an ideal public information display medium for displaying text, images, two-dimensional or three-dimensional animations, and video signals such as television, video, and VCD. Existing display screens only rely on heat dissipation holes on both sides of the display screen to dissipate heat, and industrial display screens generally work for a long time. Therefore, the heat dissipation effect of the heat dissipation holes alone is not good. In the long run, the service life of the display screen is greatly reduced and the industrial cost is increased. Therefore, a display screen with a heat dissipation device is urgently needed. Application No. 2018108359241 discloses a heat dissipation device for an ELO industrial touch display. The utility model increases the heat dissipation area and greatly improves the heat dissipation effect by providing a rotating heat dissipation fan inside the heat dissipation frame. A cooling pipe that fits closely to the back of the display is provided to increase the heat exchange area between the display and the cooling pipe, and accelerates the heat dissipation speed of the display. The combination of the two heat dissipation devices achieves a double heat dissipation effect without affecting the heat dissipation of the display body, so that the heat dissipation effect is maximized and the labor intensity of personnel is minimized. However, the following problems still exist: First, the heat dissipation efficiency is low, and only the heat dissipation is performed on the surface of the display screen. If the display components are separated for heat dissipation, the heat dissipation effect will be better; Second, water-cooled heat dissipation is prone to produce condensed water, which will damage the circuit.
