Temperature test apparatus with ventilation block for anechoic box
A recently granted patent (Publication Number: US11994550B2) discloses a temperature test apparatus designed for testing devices in controlled temperature environments. The apparatus comprises an anechoic box, a heat insulating housing, a temperature control device, a ventilation block with through-holes, and first and second covers to create spaces for gas flow. The through-holes in the ventilation block are strategically sized to prevent test radio waves from passing through while allowing controlled temperature gas to flow. Additionally, the apparatus includes features such as pipe fittings for gas supply, exhaust fans for gas discharge, and a test antenna for measuring transmission characteristics of the device under test.
Furthermore, the patent also details a temperature test method utilizing the described apparatus. The method involves controlling the temperature in the heat insulating housing to various predetermined levels, sequentially adjusting the posture of the device under test, and measuring transmission or reception characteristics of the device as the posture changes. This method allows for comprehensive testing of devices under different temperature conditions while ensuring that test radio waves are not interfered with. Overall, the patented temperature test apparatus and method provide a sophisticated and controlled environment for accurate testing of devices, particularly in the field of radio signal transmission and reception.
