Introduction: today bunny to introduce you to the knowledge about homemade heat pipe radiator, for heat pipe radiator we are more familiar with the heat pipe, heat pipe is in fact has a very high thermal conductivity of the heat transfer element. It was invented in nineteen sixty-four. In fact, today we mainly talk about is how to homemade heat pipe radiator. In fact, the principle of homemade heat pipe radiator and the market heat pipe radiator are the same, you can understand. Next to the big detailed explanation of the process of homemade heat pipe radiators.
One, the production of homemade heat pipe radiator
The production of heat pipe heat sink material is very simple, we need a piece of radiator and the bottom of the area of the same size as the square-type copper, the thickness should be more than 1CM, of course, with the aluminum block can also be. Two copper tubes for refrigeration with a length of 15cm and an inner diameter of 3-5mm can be replaced by a TV antenna of the same diameter.
1, in the aluminum block 1.5cm apart, drill several holes as thick as the copper tube, and then insert the copper tube into the aluminum block. During the insertion process, it is best to coat the surface of the copper pipe with CPU thermal grease, which is conducive to heat dissipation.
2.? Use solder to flatten one end of the two copper tubes and seal them, and then bend the copper tubes into shape, with the ends cocked upwards like a pair of horns. This allows the warped portion to be blown by the CPU's cooling fan.
3.? Use a syringe to suck up a dozen milliliters of alcohol and inject it into the copper tube, note that it does not need to be filled up here, and suck out the extra alcohol with a syringe to ensure that the heat conductor only takes up 3/4 of the volume of the copper tube, so that there is room for the flow of internal gases.
4, sealing the entire heat conduction tube is the most difficult step, again with solder but must pay attention. First of all, the speed should be fast, otherwise the temperature of the soldering iron will be alcohol heat conductor are evaporated dry. Secondly, the seal must be tight, otherwise there is no thermal conductivity after the evaporation of the thermal conductor.
Two, the working principle of the heat pipe radiator
Heat pipe is a heat transfer excellent artificial components, commonly used heat pipe consists of three parts: the main body of a closed metal tube, a small amount of internal working medium and capillary structure, the tube of air and other debris must be excluded. Heat pipe work using three principles of physics:
(1) in a vacuum, the boiling point of the liquid is reduced;
(2) the latent heat of vaporization of the same substance than the apparent heat of the high;
(3) the porous capillary structure of the liquid's suction can be made to liquid flow.
The above about the heat pipe principle of heat pipe radiators to give you a detailed introduction, I believe you have a certain understanding of the heat pipe radiator. On the homemade heat pipe radiator to give you a detailed explanation, I hope it can help you. We must pay attention to the production of heat pipes when the choice of heat pipes must be long, as far as possible, not less than actually millimeters, as far as possible, but also a little thicker, not less than five millimeters.
