The present invention relates to the technical field of display devices, and in particular to a display device with a heat exchange module and a heat exchange method thereof.

Generally, the heat dissipation structure uses a fan or an air conditioner, wherein the heat dissipation effect of the air conditioner is better, but the air conditioner also has a greater size, higher noise, higher power consumption and poorer environment-friendly benefits. Therefore, the fan is commonly used in the heat dissipation of the display device. A prior patent (with the patient application number of 201620556677.8 and the tile of Sealed Display Terminal) of the inventor discloses a sealed display terminal, a sealed space is formed inside the display terminal, a display module is arranged in the sealed space, and a circulation airflow is formed in the sealed space to perform heat dissipation on the display module. Further, in the technical solution, heat dissipation fins are also arranged on a casing so as to perform an inside and outside heat exchange effect for lowering the temperature inside the sealed space. However, the heat dissipation capability of the heat dissipation fins can only meet general display function modules, and the heat dissipation effect on high-power component expansion (such as PC and cameras) is limited.
