What is thermal shock chamber?

What is thermal shock chamber?

Thermal shock chambers are the means through which alternating extreme hot and cold air is applied to products to test their durability and identify breaking points. The method reduces the potential for failures.

How does a heat chamber work?

Temperature chambers, or environmental test chambers, perform thermal tests using forced air convection. In many ways, they operate much like an oven. Their main requirement is air flow, which is powered by a fan and motor to cycle air in the test chamber.

What is an environmental test chamber?

Environmental test chambers are systems that allow users to manipulate the environmental conditions of an enclosed space to run controlled tests on a subject. Researchers, engineers, scientists, and manufacturers utilize these conditions to push innovation and ensure whatever products they produce are safe for use.

What is thermal shock test?

Testing. Thermal shock testing exposes products to alternating low and high temperatures to accelerate failures caused by temperature cycles or thermal shocks during normal use. The transition between temperature extremes occurs very rapidly, greater than 15 °C per minute.

What is thermal failure?

Rapid changes or extremes in temperature adversely affect optical components in several ways, including fracture, delamination, loss of annealing, permanent shape change, and degradation of cement bonds.

What is a thermal chamber used for?

The electronic control system allows one to perform axial stress-controlled or axial strain-controlled tests. A thermal chamber is used for thermal conditioning of specimens during tests. Temperature is measured using a thermal sensor (e.g., a PT100 temperature probe) fixed on the surface of the specimen.

What are thermal vacuum chamber used for?

The thermal vacuum chamber is used to heat and cool devices by way of conduction or radiation. Thermal platforms, use Liquid Nitrogen or other refrigerant liquid to maintain cold temperatures and radiant or conductive heaters to keep the temperature at a hot set point.

What does a thermotron do?

With more than 50 years of experience, Thermotron is a premier manufacturer of high-performance environmental test chambers and vibration test systems. We build equipment to challenge the limits of our clients’ products while making unique chambers to test temperature, humidity, altitude, and vibration.

At what temperature does thermal shock occur?

Thermal shock is the rapid cooling or heating of an object usually at a defined rate of, eg, +10°C/min or via the immediate transfer from one temperature chamber to another.

Why thermal shock test is required?

Thermal shock testing is performed to help determine the ability of electronic components to withstand rapid changes in temperature. Due to the extremely high rate of change of temperature, it is considered to be a severe test.

How do you test for thermal fatigue?

Thermal fatigue experiments are generally conducted by heating a specimen and subsequently quenching it in water or air. The damage is evaluated by measuring a characteristic property of the material, as the elastic modulus or the mechanical strength, after successive thermal shock cycles.
