Problems solved by technology
Passive heat dissipation means that the heat generated by the display screen is diffused by means of thermal diffusion. The existing display screens have a compact structure and a small space for heat dissipation, and in order to prevent foreign matter from entering the display screen, the appearance of the display screen is relatively airtight. Well, it is also not conducive to heat dissipation, so this heat dissipation method not only has low heat dissipation efficiency, but also has poor flexibility, and cannot perform individual heat dissipation optimization for a certain area

The invention discloses a heat dissipation mechanism and display equipment, and belongs to the technical field of heat dissipation devices. The heat dissipation mechanism comprises a heat dissipation module, wherein the heat conduction piece of the heat dissipation module is provided with a containing cavity, a columnar heat conduction part and a ventilation opening communicated with the containing cavity, the columnar heat conduction part is arranged in the containing cavity, a cap movably sleeves the columnar heat conduction part, a volume-variable sealing cavity is formed between the cap and the columnar heat conduction part, the heat conduction piece can guide heat of to-be-cooled equipment into the sealing cavity so as to push the cap to move along the columnar heat conduction part to switch the cap from a first state of blocking the ventilation opening to a second state of opening the ventilation opening, and after the ventilation opening is opened, cold air enters the containing cavity through the ventilation opening, and then heat dissipation of the equipment to be cooled can be accelerated. The heat dissipation mechanism not only is high in heat dissipation efficiency and good in heat dissipation effect, but also can be provided with a plurality of heat dissipation modules according to requirements, is high in flexibility, and can perform independent heat dissipation optimization on a specific area. The display equipment is good in heat dissipation performance.
Description
technical field [0001] The invention relates to the technical field of heat dissipation devices, in particular to a heat dissipation mechanism and a display device. Background technique [0002] Display devices such as display screens will generate a lot of heat during the working process, and dissipating the heat in time is of great significance to the performance and service life of the components in the display screen. The heat dissipation performance of a display screen is an important factor determining its quality, and most existing display screens use traditional passive heat dissipation methods. Passive heat dissipation means that the heat generated by the display screen is diffused by means of thermal diffusion. The existing display screens have a compact structure and a small space for heat dissipation, and in order to prevent foreign matter from entering the display screen, the appearance of the display screen is relatively airtight. Well, it is also not conduciv...
