How is heated air pushed out of a computer?
The heated air is pushed out of the computer via exhaust fans. What we have is a simple intake -> extract -> exhaust system, where a computer is consistently fed cool air while heated air is expelled.
What’s the difference between a heat extractor and a heat exchanger?
A kitchen or bathroom extractor fan (left) is designed to suck hot, moist air from your home and dump it outside. Since it takes one fluid (the hot air in your home) and mixes it with another one (the cold air outside), it’s not a heat exchanger. It’s just a heat extractor. A hot-water radiator (right) is more tricky.
Which is an example of heat conduction between two objects?
There are many examples of heat conduction. Any time two object touch, heat conduction will happen. Touching a hot iron is an example of conduction – the heat passes out of the iron and into your hand. So is holding an ice cube – the heat is conducted out of your hand, and into the ice cube (that’s why your hand feels cold).
What should the air flow be in an air heating system?
Required Air Volume in an Air Heating System. As a rule of thumb the air heating supply temperature should be in the range 40-50 oC. The air flow should be in the range 1-3 times the room volume.
What are the different types of air inlets?
There are many different styles of commercial air inlets available. The type of inlet chosen will depend on what type of distribution pattern is needed.
Required Air Volume in an Air Heating System. As a rule of thumb the air heating supply temperature should be in the range 40-50 oC. The air flow should be in the range 1-3 times the room volume.
What causes the opening of air inlets to be different?
Cable stretch over time with actuated air inlets will cause non-uniformity in the opening size of inlets. As the cable stretches, inlets nearer the machine will open more than the inlets farther away, which could result in uneven temperatures.
What should the air temperature be in an air heater?
As a rule of thumb the air heating supply temperature should be in the range 40-50 oC. The air flow should be in the range 1-3 times the room volume.
