Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The invention provides an outdoor electronic device, which provides a new type of heat dissipation method for the electronic device, which includes both closed type conduction heat dissipation through heat exchange and heat dissipation through the shell, and open type ventilation heat dissipation through the back of the shell The upper cover is provided with an outer cover body, and a heat dissipation space is formed between the outer cover body and the back of the casing. The heat dissipation effect of the device. The outdoor electronic equipment of the present invention ensures the cleanliness of the internal air through the airtight casing, thereby ensuring the display effect and service life of the display module. By setting the heat dissipation module, the low-temperature external air is used to quickly cool down the back of the cas...

Abstract

The invention relates to outdoor electronic equipment comprising an enclosed shell and a display module arranged in the shell. The outdoor electronic equipment is characterized in that a cooling module is detachably arranged on the back of the shell in a covering manner and comprises an outer cover body communicated with the outside and a cooling fan mounted to the outer cover body. The enclosed shell is used for mounting the display module, cleanliness of air inside the shell can be ensured, influence on display effect of the display module due to dust is avoided, and service life of the display module is ensured. Cooling is realized by heat exchange through the shell, the cooling module is further arranged on the back of the shell and can cool the back of the shell by forming cooling airflow with the aid of outside air, cooling effect of the back of the shell is improved, and cooling effect of the display module is further improved.

Description

technical field [0001] The invention relates to the field of heat dissipation devices, in particular to outdoor electronic equipment. Background technique [0002] At present, outdoor electronic equipment such as outdoor advertising machines generate heat due to their electronic components. After running for a period of time, the temperature of the advertising machine is relatively high. If heat dissipation is not carried out, it is easy to cause damage to the electronic components. [0003] Existing advertising machines are generally equipped with cooling devices for cooling the advertising machine to ensure the service life of the advertising machine. The existing heat dissipation devices can be divided into two types. One is to install a fan in the airtight outdoor advertising machine to form an internal circulating air for heat dissipation. The advantage of this cooling method is that it can ensure the cleanliness of the air in the outdoor advertising machine. Avoid the...
