Thanks IRStuff
I agree that white will be a direction I push. The shade is ideal but the problem with this application is that it needs to be somewhat portable on a jobsite. They will move it and connect to a computer.
I think the solar strap is a good idea, I will have one full side of...
IRStuff and Hendersdc,
Thanks for the suggestions thus far!
I think IRstuff has deep knowledge on solar radiation, http://www.eng-tips.com/viewthread.cfm?qid=393819
I read into the mil standard he mentioned and it was interesting/enlightening.
Just wonder if anyone has that calc sheet that...
Hendersdc,
I agree about the air flow calc area for aspirated air, unless there is serious heat pipes directing the internal air, it would be almost equal.
On my calc sheet, I need to add solar heat gain, any help would be much obliged. Then I would add the solar heat gain with the 80w...

Could I use 2 or three of these mounted externally? Maybe I can use conduction from electronics to thermal grease to inner wall the solder and mount this on the external housing with a protective cage/filter around it? to this mounted externally? Then I...
Thanks for the follow up and clarification on the hoffman document, I will have to agree with you and IRstuff on the finish if you are both mentioning it. I know the nema 4x STAINLESS panels usually have a polished finish so that is probably what they are comparing.
I guess the white values...
No where in the literature does it mention a polished metal. They are comparing the different coatings that can be applied to an enclosure. That is why white is listed under metallic. So if I paint the enclosure white, it will reflect more energy.
When they speak of metallic finish, they are...
IRStuff,
Thanks for the heads up on double post, I thought that there might be some ideas from electrical engineers in the enclosure thread. If it is against the forum rules for double post, I will remove the one I just added in electrical engineers.
On the hoffman document, I am reading the...
Thanks for pointing me in the right direction, it looks like I will need liquid cooling or force the electrical engineers to go up in component ratings. The only issue is that there is a legacy electrical component that must be used.
Just to clarify and further my understanding,
I understand...
Thanks Hendersdc,
What about natural convection with 84 CFM internal forced air flow(closed loop)? Will this just ensure the temps are more uniform, or will this add to the cooling?
Thanks IRStuff for the reponse

1. Jumped to delta T as the heat load but dont show how I got there from actual heat load of 80w
- I was...
Hello all,
First time post, long time reader.
I am designing IP65 Electrical Enclosure with 80w internal Heat load. It is small and dont have a lot of room for vents, the only IP65 vents I see are made for large off the shelf enclosures.
I have 2 questions:
1. What is the external solar...
