Morphology
The term directly combines 'heat' (thermal energy) with 'dissipation' (the process of dispersing or losing something), so the meaning — the process by which heat is released or spread out from a system — is compositional and immediately derivable from the parts. This construction is cross-linguistically common (e.g., disipación de calor, dissipation de chaleur), so a B1 learner who knows both constituents would readily understand it.
Etymology
Heat dissipation shows a simple picture: heat moving away from something hot, like steam leaving a kettle. It means the process of letting warmth 'escape' or be 'lost' from a device so it does not 'overheat'.
