is there a way of calculating the required cooling rate for a given component ?
Answers
Answer:
Determine the dimensions of the room or home that needs cooling. For a room, you can do this with a measuring tape. ...
For a room, multiply its length by its width to get the square footage.
Multiply the square footage by 20. This is the measure of the BTU cooling load of the space.
Answer:
Forced air cooling of electronic components results in a dramatic improvement over natural convection cooling. This effectiveness is the result of the following:
Reduction in the temperature of the air in the vicinity of the components being cooled.
Improvement in the heat transfer coefficient of the components transferring heat to the air surrounding them.
Although the best way to make an accurate determination of cooling requirements is by actual test of the equipment to be cooled; a good approximation of the amount of air required can be determined from the mass flow relationship:
q=wCpΔt (Eq. 1)
Where q = amount of heat absorbed by the air in BTU/hr
w = mass flow of air in lb/hr
Cp = specific heat of air in BTU/lb °F
Δt = temperature rise of the air in °F
