The heat pipe can transport heat over longer distances and connect devices which produce and use heat. Currently this is limited to heat exchangers and nuclear reactors.
Heat pipes have a heat capacity of 1 MJ/°C. Thus, they can theoretically buffer 500 MJ of heat energy across their working range of 500°C to 1000°C, making them a space-efficient energy store. However, because temperature needs a drop of greater than 1 degree before it will "flow," you can't raise them all the way to 1000°C or drain them all the way to 500°C, so the practical energy capacity will depend on the layout.
As heat pipes rise in temperature, they will give off a very low-distance glow.
Heat pipe throughput
Heat pipes are acting very similarly to fluid pipes: they each hold an amount of heat energy and there is a limit to how much of that energy can go through each of them for a given duration.
For any heat pipe entity with one input connection on one side and one output connection on another, this entity with lower the temperature by 1 + (P / 15) °C with P being the power going through this entity expressed in MW.
Since a nuclear power plant can have at most 500°C difference between the hottest (a nuclear reactor) and coldest (a heat exchanger) points of the system, that means that we can express the maximum length of a straight line of heat pipe as 500 / (1 + P/15).
For example let's take a single nuclear reactor outputting 40MW of heat power to a single line of heat pipes. The furthest that line can go is 500 / (40/15 + 1) which is around 136 heat pipes long.
History
- 0.17.67:
- Heat pipes (also in reactors and heat exchangers) glow with high temperatures.
- 0.15.11:
- Changed heat transfer mechanics, prior to this heat would flow better following the order of heat pipe placement
- 0.15.0:
- Introduced
