Why not put servers in a refrigerator?

Recently I was thinking about home improvement, and one idea that is haunting me is that I could use some kind of refrigerator for gaming consoles and laptops. The obvious benefit is that it maintains a constant low temperature. Also, the doors…

How to design a house to be cooled passively?

I live in Louisiana these days, in an area that is known for its numerous antebellum plantation homes (circa early 1800s). While touring one of these homes it was clear that almost everything about the house was designed around keeping cool in the…

How are passive houses made in very hot regions (like Saudi Arabia)?

I think, here is the main problem the difference between the internal and the external temperature. For example, in Saudi Arabia, in 50 C, a passive house needed probably much sophisticated planning as in Paris. Compared to the traditional cooling…

Why are all computer fan blades thin?

100% of all PC cooling fans from 90s to today, from 40mm to 200mm, from budget to most expensive high performance models, they all use thin blades. Why? Airplanes wings and propellers use more complex thick "airfoil" shapes. Wouldnt a thick airfoil…

How does the shape of CPU/GPU fan blades affect their performance and loudness?

I need to replace the fan on my graphics card. The original fan is exactly like this one but there is another fan that seems to be a new revision of the same model number from the same manufacturer (NNTG vs. NNTM). The main difference seems to be…

Radiators in series or parallel?

So let's say I have some heat generating machine be it a combustion engine or a fridge cooled by a fluid. I don't have a single radiator that is big enough for the amount of heat being generated but I do have a couple of smaller ones so I guess I…

What happens to silicone gaskets (siloxane rubber) in presence of ethylene glycol?

Normal sealings and gaskets are made from NBR for use in conjunction with aqueous solutions of ethylene glycol which are common coolants for various purposes. However to keep sulphur out of a cooling system and the surrounding area I want to change…

How effectively would a typical liquid CPU cooler cool a 15"x15"x1/8" sheet of aluminum?

I'm curious about whether a typical liquid CPU cooler (like, e.g., this Corsair H60) would be able to effectively cool a square sheet of aluminum with 15" sides and a thickness of 1/8". I'm not even sure how to properly formulate the question so…

Do heat pipes work in any orientation?

I think I understand how heat pipes work, and thus the following one has me flummoxed:- It's from a typical bulk order Chinese web site, but I've seem many similarly contorted arrangements. They are very common in the over clocking /modding…

What's more energy efficient: fewer air conditioners working at max capacity or more working at part capacity?

The central heat and air in the house I'm renting is unable to keep the house below 80 °F during the hot summer here (100 °F days). We've had 3 HVAC techs out to look at it and they all say there's "nothing wrong with the system" and that it's…

What are heat sink options for a circulating-water cooling vest?

I am in a first-year engineering design group where we are in the process of designing a cooling vest for motorcyclists for use in the city (1-2h length). Water will circulate through the vest, absorbing body heat, and then that heat will be dumped…

Why do a swamp cooler and dehumidifier effectively cool a room when paired together in an enclosed space?

I've read in more than one place (e.g., here and here) that a swamp cooler (a.k.a., evaporative cooler) can be effectively paired with a dehumidifier to cool an enclosed space, but this makes no sense to me. It seems like the evaporative cooling…

How much pipe would I need in the ground to cool an outbuilding?

I want to experiment with geothermal cooling, and have an r-10 insulated workshop which I'd like to cool during the worst of the summer heat this year. The workshop is about 400 square feet (37 m2), and 11' (3.3 m) ceilings, with a concrete…

Use two passive CPU coolers on one single CPU?

I aim on building a silent, completely passively cooled PC, with no moving parts at all (I am aware that it is cheaper to go for an inaudible computer instead, using low speed fans. This is not the point.). I came up with the idea to install not…

How to remove heat from an IP66 enclosure?

I have a small IP66 polycarbonate enclosure with a Zirconia-based oxygen sensor which produces significant amounts of heat (the internal sense element runs at 450C using a 1.5W heating element, sensor surface reaches 85C). The enclosure also…
