Etymology: "Convector" is built from "convect" plus the suffix "-or," which marks a person or thing that performs an action. "Convect" comes from Latin "convectus," the past participle of "convehere," meaning "to carry together" or "to bring together," formed from "con-" (together) and "vehere" (to carry). The Latin "-tor" agent ending, which passed through Old French "-eor" and Middle English "-our," reached English as "-or," the same suffix found in words like "actor" and "inventor." The sense of carrying has narrowed considerably. In physics, convection describes heat moving through a fluid as warmed material rises and cooler material sinks, so the heat is physically carried along by the moving fluid. A convector applies that principle, warming the surrounding air so that it circulates through the room, which explains why these devices are typically mounted low on a wall, where cool air collects before being heated and rising.

Synonyms: radiator, heat exchanger
