Structure of the Temperature Test Chamber

The core structure of the temperature test chamber includes the chamber body, a heating and cooling system (wide temperature range of -70℃ to +150℃), a temperature control system (±0.5℃ accuracy), and an air circulation system (wind speed 1-1.5m/s). The chamber body is made of 304 stainless steel, combining high strength and airtightness (heat leakage ≤5%) to ensure a stable testing environment. The heating system achieves rapid heating (5℃/min) through nickel-chromium alloy heating wires, while the cooling system uses cascade compressor refrigeration technology to ensure low-temperature stability. The PID intelligent temperature control system adjusts the heating and cooling output in real time, and works with a centrifugal fan to achieve forced convection, ensuring a temperature uniformity of ±2℃ within the chamber. This modular design can meet the precise temperature control requirements of military applications, electronic component aging, and other scenarios.
