Heat transfer from a heated enclosure to a temp sensor in open air.

Hello everybody,

I am trying to figure out if a heated enclosures will effect my temperature readings from a temperature probe. As shown in the picture below, the arrow in the middle shows an enclosure 9"x7"x8" that has a 30 watt heater inside and a battery backup system 27"x 22" x 18" on the right that dissipates 200 watts. The temperature probe is on the far left. I want to find out with a variable wind speed how this heat dissipation will affect my atmospheric readings. In my opinion, there won't be a big difference, but I need some calculations to back this up. Thank you.

It is difficult to provide an exact answer without more details about the design of the enclosures and the ambient environment. However, in general it is likely that the heat generated by the enclosures will have some effect on the temperature readings from the temperature probe. The amount of effect will depend on the size of the enclosures, the thermal conductivity of the materials used for the enclosures, the type and amount of insulation used, and the amount of air circulation in the area around the enclosures. Additionally, if the enclosures are located close to the temperature probe, then the effect may be more significant. If the enclosures are located far away from the temperature probe, then the effect may be less significant. To get a better understanding of the potential effects of the heated enclosures on the temperature readings from the temperature probe, it may be best to perform some experiments in which the enclosures are turned on and off and the temperature readings are recorded. It would also be helpful to measure the air temperature within the enclosures and compare to the temperature readings from the temperature probe. This could provide useful information about the amount of heat transfer occurring between the enclosures and the surrounding environment.
