In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, an electronic information display device according to the present invention includes a main display panel 1, a heat dissipation back case 2, and a transparent square tube 3; the main display panel 1 is a common electronic display device, and during operation, elements such as an integrated circuit generate a large amount of heat;

the heat dissipation back shell 2 is attached to a heating part on the back side of the main display panel 1, a hollow heat exchange cavity 21 is formed in the heat dissipation back shell, the top end of the outer part of the heat dissipation back shell is sealed, an air inlet 22 is formed in the lower end of the outer part of the heat dissipation back shell, and an air outlet 23 communicated with the heat exchange cavity 21 is formed in the upper end of the outer side surface of the heat dissipation back shell; transparent side's pipe 3 is the slim type structure that link up from top to bottom, and its length is 20 times of its width at least, water conservancy diversion hole 31 has been seted up to the upper end of transparent side's pipe 3 a side, transparent side's pipe 3 is vertical placing, and its fixed mounting is in the outside of heat dissipation dorsal scale 2, and the position is relative between water conservancy diversion hole 31 and the air outlet 23, and both can dock the intercommunication for heat transfer chamber 21 and the inside formation of heat dissipation dorsal scale 2 switch on.

In this embodiment, referring to fig. 2, the transparent square tube 3 is made of colorless transparent glass, and the upper end of the transparent square tube is fixedly connected to the heat dissipation back shell 2 through a clamp 4. The glass has strong light transmission, so that the sun can directly enter the transparent square tube 3, and the air in the transparent square tube is rapidly heated.

In this embodiment, the heat exchange cavity 21 is at least 4/5 of the whole volume of the heat dissipation back shell 2, and the heat exchange cavity 21 can sufficiently exchange heat with the main display panel 1.

In this embodiment, the air inlet 22 is a long strip, and the length of the air inlet is at least half of the width of the heat dissipation back shell 2, so as to ensure that the heat exchange cavity 21 can form a large circulation area with the outside air, the air flow is large, and the air pressure in the heat exchange cavity 21 is consistent with the air pressure in the outside air, so that an obvious pressure difference relationship can be formed between the inside of the heat exchange cavity 21 and the transparent square tube 3.

In this embodiment, referring to fig. 2, an arc plate 5 that is tilted upward and wider than the diversion hole 31 is disposed on the upper side of the diversion hole 31.
