How does a Temperature Chamber work?

Temperature Chamber, or environmental test chamber, adopts forced air convection to perform heating and cooling tests inside the testing zone, the purpose is to evaluate the durability of a product under extreme temperatures.

To realize temperature control, the test chamber should be able to carry out two functions: heating and cooling, uniform temperature also must be evenly distributed inside the testing zone, Climatest Symor® masters the core techniques of uniform air distribution, and makes it possible to achieve a high degree of uniformity of temperature values in the whole testing zone.

Temperature Chamber uses mechanical cooling system and mechanical heating system to conduct testings on products:

Mechanical heating system consists of electric heating elements positioned near the ventilation system, so that the heated hot air is delivered into the testing zone from air inlet, then come out from air outlet, meanwhile, there are centrifugal fans located at the back of the air inlet, so as to blast the hot air to reach better uniformity.

Mechanical cooling system consists of a closed circuit system, with the following main components:

·Control valve

·Condensor

·Evaporator

·Compressor

The refrigeration system in a Temperature Chamber is classified to be single stage and double stage, the single stage is adopted with temperature -40℃ and above, and double stage (also called cascade system) is with temperature below 40℃.

What's quality difference between Climatest Symor® Temperature Chamber and other brands in China?

1. Climatest Symor® installs a water purification device inside the chamber, which is able to filter particles and impurities from water, besides, the water supplement is automatic, but our competitors don’t have, they still need to add water manually.

2. Climatest Symor® masters the environmental test chamber manufacturing technology, with independent intellectual property rights and design patents.

3. Climatest Symor® uses easy-to-operate Japan LCD programmable touch screen controller.

4. Climatest Symor® core electrical components of temperature test chamber (AC contactor, SSR, switches) are from Schneider brand, it is easy to find replacement in your local market if there is any failure, but our competitors use local brands.

Temperature Chamber Characteristics:

Application:

Temperature Chamber simulates high temperature, low temperature, and temperature alternating climate conditions to test products and materials’ durability performance under extreme climate conditions, Temperature Chamber is applicable to below industries:

Electronic& Semiconductor Industry:

The inherent reliability of electronic components depends on the reliability design scheme. During the manufacturing process, due to fluctuations in human factors or raw materials, process parameters, and equipment conditions, the final product cannot all achieve the expected reliability. In each batch of finished products, there are always hidden defects, which manifest as early failure under certain stress conditions.

Therefore, it is necessary to take measures to screen these electronic components with initial failure as much as possible before they are installed on the machine, and for this purpose, Temperature Chamber is one of the screening equipments in early quality control process:

1. High temperature testing of Temperature Chamber

High temperature screening is commonly applied on semiconductor devices, which are stored at high temperature for 24 to 168 hours. Most of the failures of electronic components are caused by surface contamination, poor bonding, and defective oxide layers, which are closely related to high temperature.

The thermal stress and screening duration of various electronic components should be appropriately selected to avoid new failure mechanisms. High-temperature screening is simple, inexpensive, and can be implemented on many components.

2. Temperature circulation testing of Temperature Chamber

Due to heat expansion and cold contraction principle, electronic devices will encounter different ambient temperature conditions during use, and those with poor thermal resistance are prone to failure, Temperature Chamber simulates temperature cyclings between extreme high and low temperatures, which can effectively eliminate products with thermal performance defects. The commonly used screening conditions for components are -55 to +125℃, and 5 to 10 cycles, it still depends on the specific requirements.

3. Low temperature testing of Temperature Chamber

How often do electronic components fail at low temperature? Most electronic components have a working temperature range, beyond this range, they will fail or performance declines, the change of temperature has a great influence on the conductivity, voltage, and current of the semiconductor devices. Nowdays, a chip often contains millions of transistors and other components,the accumulation of every small deviation have a huge impact on their final performance, thermal test chamber simulates low temperature testing condition, and help manufacturers collect data for reference in all above situation.

Automobile Industry:

Temperature Chamber is one of the most crucial environment simulation equipments in automobile industry, products are experiencing a "torture" through environmental testing, automobile parts are tested rigorously, problems are explored and initial product design plans are repeatedly revised, so as to continuously improve quality.

1) High temperature test: The high temperature environment causes thermal effects, which will bring softening, expansion and evaporation, gasification, cracking, melting and aging of automobile parts, then automobiles will have mechanical breakdown, dealing failures, poor insulation of circuit systems, and more.

2) Low temperature test: The low temperature environment causes physical contraction, oil solidification, mechanical strength reduction, material brittlement, loss of elasticity and ice and more, then the automobile will appear cracking, mechanical failure, wear increase, sealing failure and insulation faults of circuit system.

3) Damp heat test: The ambient humidity causes corrosion on the metal surface, leading to material deterioration, electrical strength and insulation resistance reduction.

Plastics Industry:

Plastic products are everywhere in our daily life, involving in household appliances, bottles and containers, automobile parts, etc. For example, plastic bottles/bags have the advantages of simple process, material saving, and less space in the circulation process, and have been widely used in product packaging, especially food and beverage packaging.

However, changes in temperature and humidity can affect the performance of plastic bottles/bags, they become soft at high temperatures, and hard/brittle at low temperatures; high relative humidity can weaken organic materials, and moisture can condense inside the package, causing corrosion or other damage, plastic bottles/bags have weak resistance to unfavorable factors such as temperature and humidity during circulation. To improve quality and strengthen competitiveness, plastic products manufacturers now pay much attention to the reliability testing of their products in the R&D stage.

Temperature Chamber provides an economical solution for a variety of testing requirements, which helps companies to discover potential defects in their products in a short time, and provides a good data reference for the improvement of their product quality.

Moreover, Temperature Chamber is also commonly applied in Communication, Pharmaceutical, Aerosapce, Military, Chemical industries, different tests are carried out according to customers’ specific requirement.
