Heat Exchanger Which To Buy?

[LeandroJVarini]

I'm putting together a chiller with a 1HP motor and I'm so putting a heat exchanger, I'm in doubt which to use, here in Brazil is difficult the find this type of component, then the only ones I got was the Koolance performance-pcs That delivery in Brazil.

In the case would be to use a chiller to cool the CPU + Mobo + GPU + Memos, which of these models can leave the fluid at the home of 20 + or - degrees? even with all the above components being used?

Koolance HXP-193 Plate Heat Exchanger

Heat Transfer: 4.0 kW (13,600 BTU/hr) (@5LPM, Delta between inlets = 20°C)
Design Pressure: 10kgf/cm2 (140 PSIG)
Design Temperature: -40°C (-40°F) min, 130°C (270°F) max
Number of Plates: 12
Channel Plate Material: SUS304 Stainless Steel
Brazing Material: Copper


Koolance HXP-135 Plate Heat Exchanger

Heat Transfer: 2.7 kW (9,200 BTU/hr) (@5LPM, Delta between inlets = 20°C)
Design Pressure: 10kgf/cm2 (140 PSIG)
Design Temperature: -40°C (-40°F) min, 130°C (270°F) max
Number of Plates: 15
Channel Plate Material: SUS304 Stainless Steel
Brazing Material: Copper


sorry my bad english

nobody knows?

I think it is a good option, as you will not surpass the 4kW mark with your system, but just check the total max heat output of your system before you put everything together: chiller unit needs to be more powerfull than all the heat generated and then have the margin to chill it under ambient temps, not telling subzero...

thanks buddy, I'll buy the Koolance HXP-193 Plate Heat Exchanger for successfully dispelling 4000w, making some approximation accounts for the 980X test at 5.0GHz with issues 500w tdp, a 480 should produce around 400w with c, being a heat exchanger as well, and should give the left over 4kw

I have the same exact model you show on your pics, ( the 4.0 kw ) I have problem with the barb, I first order G 3/8 BSB threads from Performance PC or Frozen ( it's 1 year ago) and they was not fitting well, I finally ordered them from koolance, and they work great, so you really have to order the one from Koolance.

Let's just fix some little issues here.
A heat exchanger can move an infinite amount of heat given an infinite delta between the two sides. If that example doesn't help, and I apologize, I mean to say that the so called "4 kilowatts" of load that it can "handle" is simply a measurement taken at a specific difference in temperature between the hot and cold loop. It does not mean it will handle 4 kw in a different temperature or application. However, being that it looks to be about a 10 plate heat exchanger, it will most likely handle the heat exchange in a refrigeration style setup just fine, but make sure to mount it properly (vertically) and inject liquid refrigerant to the BOTTOM, as this will create a more even distribution and will let gravity assist you in forcing evaporation.

If your compressor and metering device are not rated and then tuned to produce the amount of load you need to balance, it will not simply hold out.

thanks to them both for having me clarify my doubts.

What other type or model of heat exchanger you indicate?

thanks man! you the best!

An evaporator coil, spiral welded on another side where the fluid passes, had a good effect? about 2 meters would be good or would it Mr. bigger?

Or a spiral inside a reservoir would be good? about 2 meters or more would be good?

I seek not zero temperatures, I seek low temperature at around 20 ~ 25 on cpu, here in Brazil is very hot temperature, environment easily reach 37 degrees!

[n00b 0f l337]

I'm not sure I understand what your question is,
Do you mean what would make a good evaporator if not a plate heat exchanger?

[LeandroJVarini]

sorry my bad english!

instead of using a heat exchanger, I thought of a mount system that would cost much less, what do you think? it worth?

An evaporator coil, spiral welded on another side where the fluid passes, had a good effect? about 2 meters would be good or would it Mr. bigger?

the tube thinner and lighter with r134a is, the darker is the fluid

Or a spiral inside a reservoir would be good? about 2 meters or more would be good?


another model



this is my compressor, what you think?, as I use this for free even!

Thank you for helping me

I'd put my vote on a spiral in a reservoir with inputs to the reservoir that direct flow as to best maximize it across the coil.
Welding one coil to another just seems to be a horrible transfer of energy.

is already decided, anything new or come back here!
