Title: Comfort Cooling Using Fans
Date Posted: Friday, 31 May 2013 15:47
In last month’s newsletter, we discussed cooling products using fans.  Almost immediately, an application came up that pointed out the weaknesses of that process. You must be able to contain the cooling air to effectively use it (the product has to be a large portion of the cross sectional area of the cooling air blast zone), and there must be an adequate difference between the cooling air temperature and the final part temperature.
This month, we will look at providing comfort cooling.  One unique subset of those applications is the ability to provide a high velocity blast zone at a long distance from the fan.  In our terminology, we call that, "spread and throw."

Title: Cooling Products Using Fans

We learn as small children that you can cool things using an airstream.  From our earliest memories, we are taught to blow on our hot food, blow on our finger if it gets burned, etc.  We can use that experience to also cool products in industrial applications.

There are two definitions that you need to understand as we begin.  The intensity of the heat is commonly measured with a thermometer, and has units of degrees Fahrenheit (oF) or degrees Celcius (oC).  The amount of heat that needs to be removed is given the units of British Thermal Units (BTU).  One BTU is 1/180th of the amount of heat needed to raise or lower one pound of water by one degree Fahrenheit from 32 oF to 212 oF.  There is an equivalent value in the SI system, but since it is so much fun to use the IP system, we’ll continue using it in our examples.

Title: How can I reduce the noise coming from my fan?

How can I reduce the noise coming from my fan?

This is a common question these days.  Like most things in life, the noise generated by a fan is often the symptom of an underlying problem.  Many times, reduction in noise levels starts with a basic understanding of how noise is generated, how to properly select and install fans, and how to treat the resultant noise.

A whole book could be written about how to reduce fan noise, but we’ll only address a couple areas today.  The first one is proper selection of the fan.  The list is quite long, but two of the most common things that happen during fan selection is that the customer wants to squeeze everything they can out of a small fan, thinking that will save money.  In some respects, it does (usually a lower cost fan, smaller footprint, etc.), but in other way, it costs more (higher power requirements, more maintenance, etc.).  One important aspect is that a smaller fan, running at higher speeds, will typically generate more noise.  This isn’t a blanket statement, of course, but is generally true.
