Description

Direct Heat Exchangers equalize the temperature of the two input networks.
- Stationpedia

Exchanges heat between two pipe networks very quickly, ~10x as fast as the Small Direct Heat Exchanger. It's counterpart is the Counterflow Heat Exchanger. _{pun intended}

Usage

It's purpose is to equalize the temperature of two pipe networks without allowing their contents to mix.
The heat exchanger does not have an internal volume and instead transfers heat directly between the two input pipe networks. A meter on the side displays the heat exchange rate in joules per tick.

Heat Transfer

Heat will flow from warmer to colder at a rate that increases with a greater difference in temperature. Newton's law of cooling can be used to approximate the rate of heat transfer according to the equation:

      Rate = k(T1-T2)

Where:

      k = 425 Heat Exchange constant (Rough estimate)

      T1 = Input 1 Temperature 

      T2 = Input 2 Temperature 

Notes

• It has no logic port
• Requires frame support, unlike the small heat exchanger
• In older versions, heat exchangers had 2 inputs and 2 outputs intended for active liquid flow. This feature has been consolidated in the form of the counterflow heat exchanger
