The first housing 30 includes an inner housing 31, a base 32, and an antenna mount 33. The inner housing 31 is assembled to the base 32 to form a mounting cavity 34, and an antenna holder 33 disposed outside the mounting cavity 34 is connected to the top of the inner housing 31. The bottom and/or the side of the first casing 30 is provided with an air inlet 35, the top is provided with an air outlet 36, specifically, the air outlet 36 is provided at the top of the inner casing 31, the air inlet 35 can be opened on the base 32, or can be opened at the periphery of the inner casing 31, or can be opened at the outer peripheries of the base 32 and the inner casing 31 with the air inlet 35, in fig. 2, the air inlet 35 is opened on the base 32 as an example. The external air introduced into the installation cavity 34 through the air inlet holes 35 can flow out through the air outlet holes 36.

Because the first shell 30 is accommodated in the accommodating cavity 45 of the second shell 40, a user cannot directly touch the first shell 30 with relatively high temperature, and the user experience is improved.

The second housing 40 can be made of plastic, metal or a combination of plastic and metal.

In one embodiment, the longitudinal direction of the cylindrical airflow channel 44 may be perpendicular to the plane of the air outlet 36 of the first housing 30, so that the air in the data terminal device 100 may rise along the cylindrical airflow channel 44 with a vertical slope to reduce the resistance of the cylindrical airflow channel 44 to the air flowing through.

The temperature of the air increases after passing through the heat source 10 in the installation cavity 34, so that the temperature of the air inside the data terminal device 100 is higher than the temperature of the air outside the data terminal device 100, and the temperature difference generates a difference in air density, thus creating a pressure difference to drive the flow of the air inside and outside the data terminal device 100. The air with high internal temperature of the data terminal device 100 rises due to low density and is discharged from the cylindrical airflow channel 44, and at this time, a negative pressure region is formed in the original place of the low density air, so that the air with relatively low external temperature and relatively high density of the data terminal device 100 is sucked from the air inlet hole 35, and the air inside and outside the data terminal device 100 is pushed to flow, and a chimney effect is formed.

The strength of the chimney effect is related to the height difference between the air inlet 47 and the air outlet 48, and the larger the height difference between the air inlet 47 and the air outlet 48 is, the more obvious the hot-pressing effect is. As shown in fig. 3, in an embodiment, the distance d between the air outlet 48 and the air inlet 47 in the longitudinal direction of the cylindrical airflow channel 44 is greater than 50mm, so as to enhance the convection of air inside and outside the data terminal device 100.
