Heat Batteries
A ''Heat Battery'' is similar to a heat store. The difference is that heat stores have a water tank with pre-heated water inside and ''Heat Batteries'' have container with a NON TOXIC ''phase change material'' (PCM), a heat exchanger and an immersion inside.
Heat sinks, Part 1: Thermal principles Frequently Asked Questions
Conduction is the flow of heat through solid material and is how the heat of the component being cooled reaches the heat sink itself. However, it is generally not how the heat sink''s heat is removed, but it can be as in cases where the heat sink is mechanically attached to another solid (such as a PC card''s metal edging and the card …
