	Exchanges heat between two pipe networks very quickly, ~~~10x as fast~~ as the [[Kit (Small Direct Heat Exchanger)‏‎\|Small Direct Heat Exchanger]]. It's counterpart is the [[Kit (Counterflow Heat Exchanger)‏‎\|Counterflow Heat Exchanger]]. <small><sub>pun intended</sub></small>		Exchanges heat between two pipe networks very quickly. Comes in two variants, large and super large, which both act as bulkier upgrades to the [[Kit (Small Direct Heat Exchanger)‏‎\|Small Direct Heat Exchanger]]. It's temperature-swapping counterpart is the [[Kit (Counterflow Heat Exchanger)‏‎\|Counterflow Heat Exchanger]]. <small><sub>pun intended</sub></small>

	It's purpose is to equalize the temperature of two pipe networks without allowing their contents to mix. <br>		It's purpose is to equalize the temperature of two pipe networks without allowing their contents to mix. <br>
	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.		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 surface area and heat exchange rate in joules per tick.

	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:<br>		Heat will flow from warmer to colder at a rate that increases with a greater difference in temperature.
