My DIY equipment rack cooler

[AutoFrank 372]

Hi,

My rack has been running hot for a while and this project is a little overdue. I decided to make my own cooling device

3 x 240V 20W fans, some plastic trunking and glue and tape, fibaro dual relay, 3 hrs and a little swearing from time to time

It vents through the ceiling to and outside space.

 

Final construction

@AutoFrank great project. Does it also suck out the bugs?

Nice work. I just cut a hole in my ceiling and have put in a ducted inline fan. The benefit of this was that I mounted the fan in the ceiling above my bathroom to keep the noise away from my media room where my goodies cupboard is

unfortunately not .. I'll try and build that into a phase 2

Thanks @fat

I started this route but access is difficult and the inline fan I got sounded like a 747

The three fans I use are very quiet but our goodies are in the utility room so noise is not an issue

 

The kids called it the funny looking gren elephant

Can I recommend the "Qubino Flush On/Off thermostat" instead of an ordinary relay? This device has a GUI bug (pun intended, see my previous post) on a HC, but I have a script to work around that.

 

The advantage: this is a standalone thermostat, it'll work without command from a controller. I own one.

I have tapes in ANY available colour, but not THAT GREEN!

Now I am jealous!

@AutoFrank here is the code to fix the GUI. EDIT: I own the non Z-Wave Plus version of this sensor, I'm not sure the newer model needs this code. Also, the newer model has a lot more parameters.

 

Please login or register to see this code.

If my memory serves me well, it has to with the fact that some factor of 10 is required when you set the temperature (so the set point is in deci-celsius, not celsius). The GUI sends degrees. So 20 degrees gets interpreted by the module as 2.0 °C. The device reports this, the script detects this and the script sends 200 deci-celsius instead. Then, the device goes to 20.0 and reports this, so everybody happy. I could me making this up. But I like this explanation.

Hi @Patrick

 

Where did you acquire the heatsink ..

It's a monster 

 

 

 

All... 

I did purchase a quibino with temp probe but had issues including it so I went a different direction...

 

I decided to head back down the UBS route with two 1 wire temp probes with one above both racks and a vd button running on a 10 minute schedule
