Receiver Position

[mHo2]

Hi, is receiver positioning an issue? I mounted mine on its side, will this create issues? (there is space between the wall and the receiver for heat to escape, and a vent at the top)

Heres a picture if im not being clear:

Dunno for sure.

I do know that they are desigjned to use cool air coming in from the bottom and venting out the top via convection.

Okay, so would you recommend changing the position or will this suffice. If i do need to change its position, i need to look for a new place to put it, im running out of room (lol).

It looks like you have adequate Venting; It should work fine

Good Luck!

Could try a "touch test". run it for an hour and check it every so often during that to see if the heat gets worrying.

And what is a worrying heat level for a class-h receiver?

Instead of being obscure, would you mind being productive and answering the question?

The heat sinks are positioned so the heat will cause convection to draw cooler air in from the bottom. This won't work if the receiver is on its side. At some point, something will get too hot, especially if it's run hard. Class H or not, they all get hot to some extent and heat is what kills electronics.

A monk asked Nansen: `Is there a teaching no master ever preached before?'

Nansen said: `Yes, there is.'

`What is it?' asked the monk.

Nansen replied: `It is not mind, it is not Buddha, it is not things.'

Ambient cooling shouldbe adequate

The heat sinks are positioned so the heat will cause convection to draw cooler air in from the bottom. This won't work if the receiver is on its side. At some point, something will get too hot, especially if it's run hard. Class H or not, they all get hot to some extent and heat is what kills electronics.

Convection cooling occur because hot air rises and their is also ambient cooling cuase by the fins of the heat sink. There have been many other cases whereby electronic devices have been rotated 90 degrees with no ill effect, primarily because the temperature never gets close to a dangerous threshold. For example many enclosed PCs can be laid flat or towered with no ill effects. One specific type of receiver Onkyo, runs hotter than others and the key factor in assuring that a thermal protect ( most electronic equipment has a thermal protect) is to ensure adequate air clearance on the top, back and both sides. It is not so much postioning the unit horizontal or vertical.

Here is a pretty good article that discusses various cooling aspects.http://robots.freehostia.com/Heatsinks/HeatsinksBody.html

Even in your vertical situation if natural convection were required to maintain cooling, you could always add forced convertion with a laptop type cooling pad such as http://www.google.com/products/catalog?hl=en&source=hp&q=laptop+cooling+pad&um=1&ie=UTF-8&cid=14343827250300502177&ei=iUslS7rUJpCCnQehwJDqCQ&sa=X&oi=product_catalog_result&ct=result&resnum=1&ved=0CC0Q8wIwAA#ps-sellers for as little as 15$.

Good Luck!

I think it's a brilliant use of space...................

Don't know about home amps and receivers but in the car world, the heat sinks of each device are only able to work if the device is flat, in the direction it's meant to face.

I have sold and installed this kind of equipment for over 30 years and have seen things work for a while in a position that "should be OK", only to have it puke. They didn't design it to be placed on its side but since no mention of added cooling was mentioned, I didn't mention it either. Of course more cooling will help but coming in from the side is the wrong place.

The reason for the forced side cooling is that was the original bottom and in accordance with your convection heat rise direction it would force air in the same direction as the orginal convection. So side air coming in from the sie is correct.

Hello guys!

I really want to be a wide receiver on varsity next year, but my football team doesn't have a summer training program. What kind of wide receiver workouts can I do to be better than the rest...

I would just run sprints, do squats and take a lot of Anabolics....

Definitely go with the steriods.....It is only illegal if you get caught. It's a same that you don't already know that.

Back on the current topic. I think you will be fine. As long as the top and bottom vents are open to vent freely, I do not see any reason why it will hurt the receiver. From the picture there appears to be plenty of clearance.
