Ερώτηση άσχετου για τα Heatpipes

[anonymous-root]

Κοιτώντας τα coolers στο σιτε της τσεκματε είδα και κάποια που έλεγαν ότι έχουν heatpipe. Μπορεί κανείς να μου εξηγήσει ακριβώς τι είναι αυτά, που χρησιμεύουν και αν αυξάνουν την απόδοση του cooler (βοηθάνε στην ψύξη) και με ποιό τρόπο;

Ευχαριστώ πολύ.

heatpipes ειναι σωληνες χοντρες και λιγες σε αριθμο που ξεκινανε απο τη βαση της ψυκτρας και καταληγουν στα φινς με περιμετρικη συστοιχια...........θα τα δεις σε high-end αεροψυκτρες.......λεγεται οτι βοηθανε

λογω παχους του σωληνα μεταφερεται ευκολοτερα και γρηγοροτερα η θερμοκρασια απο το κεντρο προς τις ακρες.......

Νομίζω ότι έχουν και υγρό μέσα. Το Thermalright XP120 τουλάχιστον. Κάπου είχα διαβάσει ένα review και κάνανε λόγο το πόσο σημαντικό είναι το πως είναι τοποθετημένο το κουτί κάθετα ή οριζόντια.

What Are Heat Pipes?

What is a Heat Pipe?

How It Works

A heat pipe consists of a vacuum tight envelope, a wick structure and a working fluid. The heat pipe is evacuated and then back-filled with a small quantity of working fluid, just enough to saturate the wick. The atmosphere inside the heat pipe is set by an equilibrium of liquid and vapor. As heat enters at the evaporator, this equilibrium is upset generating vapor at a slightly higher pressure. This higher pressure vapor travels to the condenser end where the slightly lower temperatures cause the vapor to condense giving up its latent heat of vaporization. The condensed fluid is then pumped back to the evaporator by the capillary forces developed in the wick structure.

This continuous cycle transfers large quantities of heat with very low thermal gradients. A heat pipe's operation is passive being driven only by the heat that is transferred. This passive operation results in high reliability and long life.
