Abstract

The invention discloses a special-purpose display, relates to the technical field of displays, and solves the problem of high heat dissipation cost due to the airtight structure. It includes a closed box, a display device installed on the front side of the closed box, a heat exchanger installed on the back side of the closed box, and a heat source and a heat conduction part arranged inside the closed box, the heat source It includes a power device integrated on a printed circuit board, the heat conduction part is connected to the rear shell of the closed box, the rear shell is bonded to the bottom plate of the heat exchanger, and the bottom plate of the heat exchanger There are a plurality of air channels arranged in parallel, and the air channels are in a cylindrical structure. The invention is suitable for displays with a closed box structure.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a special-purpose display. Background technique [0002] Video display devices used in some special climate environments often need to have corresponding special structures. For example, in the wild, south or coastal areas, in order to prevent the harmful effects of factors such as moisture, salt spray and mold on electronic components, it is necessary to design the video display device as an airtight structure. However, after the video display device is designed as an airtight structure, the heat generated when the display device is working cannot be dissipated in time, and the increase in the internal temperature of the display device will affect the performance and service life of electronic components. [0003] In order to solve the heat dissipation problem of a display device with a closed structure, in the prior art, the heat is exported to a semiconductor cooling chip th...
