Abstract: The present invention relates to a display device with a heat exchange module and a heat exchange method thereof. The display device comprises a casing, a display unit and a heat exchange module, wherein a sealed space is formed inside the casing; the display unit is arranged in the sealed space; and the heat exchange module is arranged on the casing. The heat exchange module is provided with first heat exchange holes positioned inside the sealed space and second heat exchange holes positioned outside the sealed space; a first circulation airflow is formed between the first heat exchange holes and the sealed space; and the second heat exchange holes communicate with outside to form a second circulation airflow for performing heat exchange with the first circulation airflow. The present invention realizes heat exchange on the first circulation airflow by the second circulation airflow by using the second heat exchange holes and the first heat exchange holes formed in the heat exchange module of an integral structure. Compared with an existing heat dissipation fin, the present invention can improve the heat exchange efficiency to achieve a fast temperature lowering effect, so that a good heat dissipation effect is achieved on the display unit.

Abstract: The present invention relates to an outdoor television with a waterproof structure, comprising: a display module, a control component of the display module and a cover body covering outside the display module and the control component, the control component being located in an upper position of the outdoor television, and the top of the cover body covering the top of the display module. According to the present invention, the top of the cover body covers the top of the display module, so that a seam is not left in the top of the outdoor television, and rainwater is prevented from permeating from the top of the outdoor television, effectively playing a role of waterproofing. Compared with existing televisions that a control component is disposed at a lower portion of a television, a mode that a control component is disposed in an upper position of an outdoor television can avoid a situation that the control component is soaked in stagnant water when the stagnant water exists in a television, so as to avoid influence of invading rainwater to functions of the control component, and ensure the service life of the outdoor television.

Abstract: An outdoor display module includes a housing defined therein a closed space and a recessed room formed in the closed space and a display device securely received inside the closed space. A glass panel is received in the recessed room and sealingly attached to a periphery defining the recessed room. The glass panel is securely and directly attached to a side face of the display device to reflect a large portion of radiation heat from the sun. A heat exchanger is received in the closed space and located at a rear side of the display device to dissipate heat from electronic devices and the backlight assembly inside the housing.

Abstract: A high-brightness liquid crystal display device includes a display module; a temperature controller abutting a back surface of the display module, a first ventilation channel being formed in the temperature controller; and fans disposed on the display module in correspondence to the first ventilation channel of the temperature controller. The fans form an airflow that flows through the first ventilation channel, to adjust the temperature of the display module. According to the present invention, the temperature controller abuts the back surface of the display module to implement temperature control on the back surface of the display module. The back surface of the display module is a lamp panel, and the temperature controller abuts the lamp panel. The airflow formed by the fans quickly reduces and increases the temperature of the lamp panel, thereby ensuring that the lamp panel works at an appropriate environmental temperature.
