The job is to calculate the amount of air (m/h) and the pressure (Pa) required to cool down a box with a sensor inside and to advise in case optimization is required. Details: 1. The box housing with the sensor inside is modelled in 3D with Solidworks. The Solidworks model will is attached. 2. The box is having a ceramic plate at the bottom and the rest is made from aluminium. 3. All holes seen in the box will be closed with bolts, apart from the socket at the top for the cooling air inlet and the row of holes at the back for escaping of the cooling air. The row at the back can be adjusted for more or less holes, as per the best air flow. The size of the inlet nozzle can also be adjusted as per flow requirements. 4. The cooling air temperature is 48C. 5. The maximum temperature inside the box shall be 80C. 6. The surrounding temperature is 200C 7. Below the 7mm thick ceramic plate a piece of material is constantly touch with 450C temperature. So, we require someone who i...
