Description

Technical Field

[0001] The present application relates to the field of PDA in the petrochemical industry, and in particular to a 5G explosion-proof PDA. Background Art

[0002] An explosion-proof PDA (explosion-proof handheld terminal) is an industrial-grade mobile device specially designed for safe use in flammable and explosive environments. It is widely used in high-risk industries such as petroleum, chemical, natural gas, mining, and military industries for operations such as data collection, inspection, and warehouse management.

[0003] Although current explosion-proof PDAs have been greatly optimized in terms of safety, durability and functionality, they still have some technical limitations and usage defects. The reinforced shell (metal + rubber) and explosion-proof structure increase the thickness and weight of the device, making it easy to get tired when held in hand for a long time. They are also large in size and inconvenient to carry. Summary of the Invention

[0004] For ease of use, this application provides a 5G explosion-proof PDA.

[0006] By adopting the above technical solution, the upper shell and the lower shell are detachable. When entering the risk area, the main body is sealed in the shell to prevent explosion.

[0008] By adopting the above technical solution, the heat conducting plate quickly transfers the heat of the main body to the paraffin-based phase change material, and the paraffin-based phase change material quickly absorbs heat and liquefies, preventing the temperature of the heat conducting plate from being too high. The heat dissipation plate dissipates heat from the paraffin-based phase change material, thereby improving the heat dissipation efficiency.

When the paraffin-based phase change material cools and solidifies, its volume shrinks, and the air pressure difference pushes the sliding block to move, causing air to enter the air outlet, thereby achieving air cooling and heat dissipation of the outer shell.

[0015] Preferably, it further includes an impeller, which is arranged between the sliding block and the air outlet, the impeller is arranged in the flow channel, and the driving column is coaxially fixedly connected to the impeller.

[0018] By adopting the above technical solution, when the temperature at a certain place rises, the paraffin-based phase change material liquefies, the gas flow drives the fan to rotate, and the fan is close to the paraffin-based phase change material, which facilitates corresponding heat dissipation and improves heat dissipation efficiency.

[0019] Preferably, a plurality of the flow channels are provided, and the plurality of channels are evenly spaced along the width direction of the shell, and the paraffin-based phase change materials in adjacent flow channels are respectively close to both ends of the shell in the length direction.

[0021] Preferably, the outer wall of the housing is fixedly connected with a heat dissipation fin, and a plurality of the heat dissipation fins are provided.

[0022] By adopting the above technical solution, the heat dissipation fins increase the friction between the shell and the operator's hand, making it easier for the operator to use. The heat dissipation fins increase the heat dissipation surface area and improve the heat dissipation efficiency.

[0023] Preferably, the outer shell also includes a rubber sealing ring, the lower shell is fixedly connected to a limiting strip at one end facing the upper shell, and a limiting groove is provided at one end of the upper shell facing the lower shell, and the limiting groove is used for the limiting strip to be embedded, and the rubber sealing ring is sleeved on the outer periphery of the limiting strip, and the rubber sealing ring is used for the upper shell to abut, and a card block is fixedly connected to the outer wall of the limiting strip, and a card groove is provided on the groove wall of the limiting groove, and the card groove is used for the card block to be embedded.
