Morphology
The meaning 'a beam of energy that produces heat' is directly and compositionally derivable from 'heat' (thermal energy) + 'ray' (a narrow beam). This straightforward noun+noun compound follows common cross-linguistic patterns, so a B1 learner who knows both constituents will readily infer the MWE's meaning.
Etymology
Heat ray creates a clear image: a thin ray like a line of light that carries very hot heat, able to burn or melt things from far away. So, it means 'a beam of energy that produces heat', often imagined as a weapon.
