Advertising machine with hidden heat dissipation mechanism

Abstract

The invention discloses an advertising machine with a hidden heat dissipation mechanism, and relates to the technical field of advertising equipment. The advertising machine comprises a shell, two fixing piles, a playing unit and a heat conducting plate, the two fixing piles are fixedly arranged on the left and right sides of the lower side wall of the shell respectively, the playing unit is fixedon the front side wall of the shell in a penetrating manner, and the heat conducting plate is fixedly arranged in the shell and abuts against the rear side wall of the playing unit; the advertising machine further comprises a passive heat dissipation mechanism and an active heat dissipation mechanism, the passive heat dissipation mechanism is arranged on the shell, the active heat dissipation mechanism is fixedly arranged in the shell, and the active heat dissipation mechanism is communicated with the passive heat dissipation mechanism; and a first chain plate is arranged on the inner side ofan air inlet and can be controlled to be opened and closed, a second chain plate is arranged on the inner side of an air outlet and can be controlled to be opened and closed, the opening and closingsizes of the air inlet and the air outlet can be controlled to make the air exchange speed inside and outside the shell conveniently controlled, and all devices are arranged in the shell to keep the attractive appearance of the shell.

Description

technical field [0001] The invention relates to the technical field of advertising equipment, in particular to an advertising machine with a hidden heat dissipation mechanism. Background technique [0002] Advertising machine is a kind of advertising equipment with audio and video playing function, which is equipped with display screen, audio and other equipment installed in the casing. [0003] In the prior art, after the advertising machine plays the picture for a long time, the electronic equipment in the equipment will generate a lot of heat due to the long-term working of the electronic equipment, which will affect the normal operation of the electronic equipment. Some advertising machines are equipped with vents to speed up the heat exchange speed inside and outside the shell. , but the size of the vent is fixed and cannot adapt to the working environment of different temperatures. When working in an environment with a large temperature difference, the heat exchange sp...

Problems solved by technology

[0003] In the prior art, after the advertising machine plays the picture for a long time, the electronic equipment in the equipment will generate a lot of heat due to the long-term working of the electronic equipment, which will affect the normal operation of the electronic equipment. Some advertising machines are equipped with vents to speed up the heat exchange speed inside and outside the shell. , but the size of the vent is fixed and cannot adapt to the working environment of different temperatures. When working in an environment with a large temperature difference, the heat exchange speed of the vent is the same, which is easy to cause the temperature imbalance in the shell. Some advertising machines have vent size control components, but this type of equipment is installed outside the shell of the advertising machine, which affects the appearance of the equipment and needs to be improved
