The NC-155S Natural Convection Chamber is a high-precision testing environment specifically engineered for the thermal performance verification of electronic products. By utilizing advanced natural convection technology, it accurately recreates a wind-free, still-air indoor environment. This design fundamentally differs from forced-convection chambers, effectively eliminating "false compliance" issues where products appear to meet thermal standards only due to artificial airflow.
Equipped with a high-precision temperature control system and a uniform heat distribution design, the NC-155S allows users to simulate real-world usage scenarios and strict high-temperature operating conditions. It is an essential tool for identifying design flaws such as overheating-induced shutdowns or performance degradation during the R&D phase. Its compact, space-efficient design ensures it can be deployed quickly without complex installation.
Temperature Range: Ambient temperature +3°C to 70°C, maximum temperature ≤70°C.
Chamber Dimensions: Inner chamber dimensions: W500mm × D500mm × H620mm.Outer chamber dimensions: W700mm × D890mm × H1360mm.
Quality Standards: A 9-point temperature measurement report is included. The standard deviation between the measured temperature at each point and the average temperature of the 9 points is <2°C.
Specified Test Temperature Points: 35℃, 40℃, 50℃, 60℃, and 70℃
Point Average Temperature: After equilibrium, samples are taken at 9 points for 10 minutes at a frequency of 10 seconds each to determine the average temperature for each point.
Test Chamber Material: 20mm acrylic glass
Door Dimensions: W483 × H640
Lifting Platform: 380mm × 230mm, effective lifting height 370mm, load capacity 100kg.
Heating Device: Ceramic infrared heating equipped with a reflector, isolation flow equalization mesh, and insulating convection perforated plate.
Control Method: The chamber is divided into two zones, each with independent temperature control (sensor, controller, and heater) to ensure uniformity.
Lead-in Holes: Dual side lead-in holes, 100mm in diameter.
Safety Protection Measures: Over-temperature protection, over-current protection, and leakage protection.
Power Supply: AC 220V / 50Hz, 10A, 1.6kW
The windless natural convection design accurately simulates the heat dissipation conditions of electronic products in real-world usage environments, avoiding test deviations caused by forced convection.
Utilizing continuous power regulation technology, it achieves temperature control accuracy better than ±0.5°C, ensuring a stable and reliable temperature baseline.
Using multi-channel zone temperature control technology, it achieves a standard deviation of ≤1.3°C as verified by third parties, providing a highly consistent thermal environment.
