In summary, the conversation discusses temperature testing on electronic equipment and the confusing results obtained. There is a discrepancy between the ambient temperature and the equipment case, which is questioned in relation to the laws of physics. Suggestions are made to provide more specific information and data for a better understanding of the situation, including considering the cooling method and measuring the exhaust temperature.

Hi everyone.
I am performing temperature tests on an electronic equipment and I am getting some confusing results. The lowest the ambient temperature, the bigger the delta between the ambient and the equipment case. How is this possible? Is there a law of physics describing this effect?
Thanks a lot

You need to be more specific about your setup, and some actual numbers would be informative.

Yes, data would be nice. But i don't see the problem. In general it might be what I would expect (within limits). How long after changing the ambient temperature are you measuring the case temperature? The ambient temperature is probably not enough to cool the equipment as quickly as the heat is being produced. Also the case temperature is not as important as the circuit boards. One more point is the equipment cooled with a fan or is it passively cooled by conduction of heat to the case. If it is fan cooled measure the exhaust temperature of the fan that is closer to the circuit board temp.
 

FAQ: Temperature Tests: Investigating a Surprising Result

1. What is the purpose of conducting a temperature test?

The purpose of conducting a temperature test is to investigate the effect of temperature on a particular substance or system. This can help scientists understand the behavior and properties of the substance or system under different conditions.

2. How do you perform a temperature test?

A temperature test can be performed by using a thermometer or other temperature measuring device to record the temperature of the substance or system at different intervals. The substance or system can also be heated or cooled to different temperatures to observe any changes in behavior or properties.

3. What is considered a surprising result in a temperature test?

A surprising result in a temperature test is any unexpected or unexpected change in behavior or properties of the substance or system at a certain temperature. This could include a sudden change in state, such as melting or boiling, or a change in color or texture.

4. What factors can influence the results of a temperature test?

The results of a temperature test can be influenced by a variety of factors, including the type of substance or system being tested, the rate at which the temperature is changed, the accuracy of the temperature measuring device, and external environmental factors such as humidity and pressure.

5. What are the potential applications of temperature testing in scientific research?

Temperature testing has a wide range of applications in scientific research. It can be used in fields such as chemistry, physics, biology, and engineering to understand the properties and behaviors of different substances and systems. It can also be used in the development of new materials and technologies, as well as in the study of climate change and its effects on the environment.
