Very helpful vedio and website. Help me a lot to understand the heat pipe. Thanks.

If we have a temperature difference of heat pipe less than 1K or greater than 5K then it will transport heat or not? if it does not transport heat then what is the reason behind it?

it is very informative video. Please let me ask a question. you showed a heat pipe modelling during the steady state case. However, can you please give any idea about temperature dependent thermal conducitivity or dynamics heat pipe modelling? how it can be modelled?

This was a great informative video. Thanks!, Learned a lot about heat pipes and also the video solved many questions that I had in my mind. Once again thnx!!

Hi, On the slide at 18mins, what is the equation you use to approximate the thermal resistances?

I recommend you use our heat pipe calculator tool, www.1-act.com/resources/tools/heat-pipe-calculator/

Hi! This is super helpful so thank you :) I was a little confused by 2K being considered a conservative estimate though, would you mind clarifying why that's the case?

1. If I dont have a heatsink but a fan instead, how do I estimate the length of my 'condensor'? 2. Is the Keff, calculated in the Advanced modelling approach for the envelope and the vapour, considered constant along the entire length of the heatpipe - including evaporator, adiabatic and condensor length?

1. You can use the entire length that would see airflow. If you don’t have any extended surfaces or fin volume, you are relying solely on the external surface of the heat pipe for thermal dissipation. In this scenario, you’ll likely have a large air side temperature rise; however the heat pipe should continue to operate with a similar delta T as described. 2. Yes

Greetings, Could you please make and post a video in your channel on step by step simulation procedure of a heat pipe using Fluent or Comsol. Thanks

Should i use K=500 to 1200 W/mK or the calcluated K_eff value of 233,000 W/mK in simulation? Whenever I talk to heat pipe manufacturers they claim max thermal conductivity value of around 2000-2500 W/mK...Please help!!

The heat pipe will operate with a fairly consistent delta T. Therefore the effective conductivity will increase as length increases; hence a range. Also the 500 - 1200 W/m-K is a range for planar effective conductivity across the entire area of a HiK(TM) plate (not a heat pipe). The heat pipe will have a much higher axial thermal conductivity. The 233,000 W/m-K you reference is the suggested k effective for the vapor space in the lumped model approach. However, if you want a single effective thermal conductivity for a heat pipe that accounts for vapor space, conduction and envelope, our suggestion is to start with 10,000 W/m-K and adjust up or down until your delta T across the pipe is within a typical heat pipe operating range (2-5 C).
