High and low temperature humidity cycle test chamber is used in aviation, automobiles, home appliances, raw materials, parts, scientific research and other fields Important testing equipment, which can meet the requirements of testing and determining the parameters and performance of electronic, electrical and other products and materials under high temperature, low temperature, alternating humidity or constant temperature environment changes. It has the characteristics of excellent reliability, accurate and controllable temperature environment change, and multi-functional adjustable humidity test, etc., and plays an important role in the application environment of high and low temperature alternating and humid heat.
Dynamic changes in temperature and humidity are the core functions of the high and low temperature humidity cycle test chamber. This article will introduce the characteristics of this type of test chamber. First of all, the test box is processed and formed by CNC machine tools, with a beautiful outer wall and an inner wall of SS304 stainless steel mirror panel. In addition, the test box is equipped with lighting and multi-layer hollow tempered glass observation windows, which have the characteristics of transparency, heat insulation, explosion-proof and not easy to generate steam and frost, and can clearly display the internal changes at any time. Secondly, the high and low temperature humidity cycle test chamber adopts multi-blade blower for air circulation, thereby eliminating dead angles, making the temperature distribution in the area even, and effectively preventing the samples from frosting and moisture. In addition, the test chamber also adopts an air circuit design to ensure that the circulating air and return air meet the standard requirements, and ensure that the temperature can be quickly stabilized when the door is opened. Finally, the High and Low Temperature Humidity Cycle Test Chamber is equipped with various functions such as color touch screen, waterproof, anti-vibration, man-machine interface and automatic system control, which greatly improves the convenience and safety of operation and meets the requirements of Application requirements in different fields.
GDJS-015B High and low temperature humidity and heat alternating test chamber
In short, through the above characteristics, it can be seen thathigh and low temperature humidity The cycle test box is a test equipment with advanced technology, powerful functions and high reliability, which can effectively meet the requirements of various industries for temperature and humidity changes.
The system of the high and low temperature humidity cycle test box has two functions: heating and cooling. The heating system outputs 3-12 volts of direct current to the solid state relay through the controller, and the heater generates electric heat to bring heat into the box Inside; while the cooling system consists of four parts: compressor, condenser, throttling device, and evaporator. Its refrigeration mainly converts low-temperature and low-pressure gas into high-temperature and high-pressure gas through a compressor.The gas discharges heat through the condenser, and the fan takes away the heat; then enters the low-pressure liquid through throttling, turns into low-temperature and low-pressure gas in the evaporator, and returns to the compressor to complete the cooling process. The function of this system enables the High and Low Temperature Alternating Humidity Test Chamber to accurately control the heat injected into the equipment and the temperature change, and provide reliable data as a reference for the performance test of the equipment.
The method of reducing the humidity of the low-temperature equipment box
The dehumidification system of the equipment box is realized by the refrigeration system installed inside. When the temperature is low, it will condense the objects with high humidity inside the equipment into liquid, so as to achieve the purpose of dehumidification of the box.
High and low temperature humidity cycle test chamber is a device that simulates the performance changes of materials under complex environmental conditions. It is mainly used for damp heat change performance test and research, and the two commonly used methods are constant damp heat test and alternating damp heat test. The constant damp heat test is to keep the temperature and humidity constant within a certain range, simulating a long-term continuous water vapor environment; while the alternating damp heat test is to set different temperatures and humidity, and to test in an alternating manner continuously, simulating Research on the durability of materials and products in a complex environment with constant temperature and humidity changes. Through the constant damp heat test and alternating damp heat test, more realistic results can be obtained under laboratory conditions, so as to study the reliability of the product more deeply.
By testing the test equipment used for a long time, the noise problem can be effectively solved from different dimensions. First of all, it is necessary to strengthen and stabilize the connection between the pipeline and the shell part of the equipment to prevent loosening and vibration to cause noise. In addition, sticking the eraser on the pipe can suppress the vibration of the air compressor and reduce the noise. Secondly, the base of the refrigeration compressor should be firm and firm to avoid noise due to improper fixing. In addition, the reverse side of the device and the wall form a certain angle of inclination to increase the air convection space at the bottom of the casing, which helps to reduce noise. Finally, raise the four corners of the device by 3-6cm and adjust the balance to reduce the noise emitted from the case. Through these measures, the noise can be effectively reduced to meet the requirements of use.
High and low temperature humidity cycle test chamber is a widely used test equipment, which can meet the requirements of various products in aerospace, automotive and electronics industries The need for environmental testing. Specifically, it can be used in the aerospace industry to test the performance of aerospace devices or aerospace devices in high-altitude and low-temperature environments; in the automotive industry, it is used to test the performance of airbags and brake systems in rapidly changing temperature environments ; In the electronics industry, it can be used to test the performance of mobile phones, computers and other electronic products under different temperature and humidity conditions. The application of high and low temperature humidity cycle test chamber not only helps to improve the quality of products, but also improves the reputation of enterprises and enhances their advantages in market competition.
