Mobile constant temperature and humidity environment aging test chamber

1、 Overview:Mobile constant temperature and humidity environment aging test chamberTo achieve precise control of temperature range from -80 ℃ to 200 ℃ and humidity range from 20% to 98% RH (under high temperature and high humidity conditions, humidity is not controlled in the low temperature stage), meeting the aging testing needs of products in industries such as electronics, photovoltaics, and automobiles in complex environments, ensuring stable equipment operation and reliable testing data.

2、 Equipment structure design

1. Outer box: Made of high-quality cold-rolled steel plate, the surface is treated with electrostatic spraying, which has good anti rust and anti-corrosion properties, is beautiful and durable, and the color is optional, usually gray white.

2. Inner box: SUS304 stainless steel plate is selected, which is corrosion-resistant and easy to clean, ensuring a pollution-free testing environment while avoiding rusting of the inner box material in high temperature and high humidity environments that may affect the test results.

3. Insulation layer: Dual insulation materials of polyurethane foam and ultra-fine glass fiber are used, with a insulation thickness of 100mm, effectively reducing heat transfer, energy consumption, and ensuring stable temperature inside the box.

4. Box door design: Single door structure, equipped with stainless steel embedded door handles, easy to operate. Double layer high temperature and anti-aging silicone rubber sealing strip is used to ensure good sealing of the box door and prevent leakage of temperature and humidity inside the box. A large observation window is installed on the door, using multi-layer insulated tempered glass with good thermal insulation performance, which facilitates the observation of the test sample status inside the box. At the same time, lighting is equipped for clear observation in low light conditions.

IIIMobile constant temperature and humidity environment aging test chamberRefrigeration system:

1. Refrigeration principle: Adopting binary cascade refrigeration technology, consisting of high-temperature and low-temperature refrigeration systems. The high-temperature stage uses medium temperature refrigerant R404A, and the low-temperature stage uses low-temperature refrigerant R23. Energy transfer is achieved through a heat exchanger to achieve cryogenic effect.

2. Compressor: Choose brand fully enclosed compressors, such as German Bitzer or French Taikang, which have the characteristics of high efficiency, strong reliability, and low noise. The high-temperature and low-temperature compressors are independently controlled, and the refrigeration capacity can be automatically adjusted according to different temperature requirements to ensure efficient operation of the refrigeration system.

3. Refrigeration accessories: Equipped with high-efficiency condensers, evaporators, drying filters, solenoid valves and other refrigeration accessories, all of which are high-quality branded products to ensure the stability and reliability of the refrigeration system. At the same time, the refrigeration system is equipped with safety devices such as pressure protection and overload protection to prevent equipment damage due to abnormal situations.

4、 Heating system:

Using nickel chromium alloy electric heating wire as the heating element has the advantages of fast heating speed, high thermal efficiency, and long service life. The heating power is reasonably configured according to the volume and heating rate requirements of the equipment, and the on/off of the heating wire is accurately controlled by an intelligent PID temperature controller to achieve precise adjustment of the temperature inside the box.

5、 Humidification system:

Using stainless steel armored humidification tubes, water is evaporated to produce steam through electric heating, achieving the regulation of humidity inside the box. The humidification system is equipped with high-precision water level sensors and water replenishment devices, which can automatically control the water level to ensure stable and reliable humidification process. At the same time, a drainage device is installed to regularly remove impurities and scale from the humidification water tank, ensuring clean water quality and extending the service life of the humidification pipe.
