Ultrahigh-uniformity natural ventilation aging test box

Abstract

The invention discloses an ultrahigh -uniformity natural ventilation aging test box which comprises a base and an outer box body, the outer box body is installed on the base, a first pore plate is arranged on the lower portion in the outer box body in the horizontal direction, a second pore plate is arranged on the upper portion in the outer box body, and an inner box body is defined by the first pore plate, the second pore plate, a first vertical plate, a second vertical plate and a third vertical plate; and an air inlet is formed in the bottom face of the outer box body, an air outlet is formed in the top face of the outer box body, the air inlet and the air outlet are both communicated with the interior of the outer box body, a groove notch with the front portion larger than the rear portion is formed in the front wall of the outer box body, a sealing heat insulation door plate mechanism is rotationally connected to the groove notch, and the rear portion of a sealing heat insulation mechanism is inserted into the front portion of the inner box body. A first compartment is arranged between the second pore plate and the bottom face of the top wall of the outer box body, and a uniform heating mechanism is arranged between the first pore plate and the top face of the bottom wall of the outer box body. The device has the advantages of reasonable design, high uniformity, good stability and the like.

Description

technical field [0001] The invention belongs to the technical field of naturally ventilated high-temperature aging chambers, and in particular relates to an ultra-high uniformity naturally ventilated aging chamber. Background technique [0002] The natural ventilation high-temperature aging box is the main equipment for environmental testing, aging screening, and heat treatment process. However, when the natural ventilation high-temperature aging box is performing environmental tests, if the temperature uniformity and temperature stability exceed the allowable deviation range, the test data will be damaged. If it is not accurate, the test data cannot be used as the test result of the material or product environmental test resistance performance, so the uniformity is one of the important parameters to measure the performance index of the aging box. In the existing naturally ventilated high-temperature aging box, uneven temperature distribution in the box may be caused by unev...

Problems solved by technology

[0002] The natural ventilation high-temperature aging box is the main equipment for environmental testing, aging screening, and heat treatment process. However, when the natural ventilation high-temperature aging box is performing environmental tests, if the temperature uniformity and temperature stability exceed the allowable deviation range, the test data will be damaged. If it is not accurate, the test data cannot be used as the test result of the material or product environmental test resistance performance, so the uniformity is one of the important parameters to measure the performance index of the aging box

The existing naturally ventilated high-temperature aging box will cause uneven temperature distribution in the box due to uneven heating of heating components, air leakage from the door panel, heat leakage from the door panel, and heat leakage from the roof panel.

In order to achieve high temperature uniformity in the box, it is usually necessary to adjust the position of the heating element, change the diversion structure in the box, etc. Even so, the uniformity in the natural ventilation high-temperature aging box is still not ideal
