In an assembly there is heat transfer between two models where I have to maintain the initial temperature of the one model same as it was initially ( since there will be rise in temperature of model which is at lower temperature initially ). There is flow of air taking place from inlet to outlet of the chamber. These two models are inside the chamber. I have used internal analysis. In the shared image below, there is baffle attached to a model. It is a type of sheet metal which is attached to direct the flow in between two models ( in order to control the temperature ) Can anyone tell me why the flow is going through the baffle.?

Note: I can't share the model due to IP related issues of the company.
