Radiation Shielding Device For Meteorological Observation With Internal Air Circulation

A radiation shielding device for meteorological observation with internal air circulation comprising:

• a body for allowing one or more meteorological sensors to be mounted therein;
• a cover for covering the body by engaging with the body;
• and
• a modified Venturi tube which is physically formed while the body and the cover are engaged with each other;
• wherein, while the body and the cover are engaged with each other, the modified Venturi tube is configured as a first opening for receiving external air from an exterior of the body, a second opening for receiving internal air from an interior of the body, and a third opening for releasing the received external air and the received internal air, and
• wherein a size of a cross-section of the first opening and a size of a cross-section of the third opening are increased along directions from a central portion of the modified Venturi tube to both ends of the modified Venturi tube, and
• wherein the modified Venturi tube performs a function of a conventional Venturi tube by using the first opening and the third opening, and allows the internal air in the interior of the body to flow into the modified Venturi tube through the second opening, and
• wherein, the first opening, the second opening and the third opening are configured such that, while a vehicle on which the radiation shielding device is mounted is moved, the external air gets into the modified Venturi tube through the first opening, the internal air gets into the modified Venturi tube through the second opening, and the external air and the internal air are released from the modified Venturi tube through the third opening to thereby allow the internal air therein to be circulated.
