## Description

> *"Direct Heat Exchangers equalize the temperature of the two input networks."*
> — Stationpedia
Exchanges heat between two pipe networks. It's next upgrade is the [Large Direct Heat Exchanger](/wiki/kit-large-direct-heat-exchanger).


## Usage

The kit produces 3 versions, gas to gas, liquid to gas and liquid to liquid. Each version has 2 pipe connections for pipe atmospheres whose contents' heat will be exchanged. The heat exchanger itself does not have an internal volume and instead acts directly on the input pipe networks. A meter on the side displays the heat exchange rate in joules (per tick).

## Heat Exchange

Heat flows from hot to cold, flowing faster the greater the temperature difference. For small heat exchangers the rate will follow 100 joules/tick per degree celcius of difference.
## Notes

- Can be placed in any orientation
- Gas in the pipe does not need to be flowing to exchange heat effectively. Stationeers treats each pipe network as one object, so cooling one end of a pipe will immediately cool everywhere else in the pipe.
