Abstract
The invention discloses a high-precision zone control temperature simulation device which comprises a fan-shaped external frame, a specular reflection plate and a plurality of armored electric heating wires, wherein the armored electric heating wires are fixed on the specular reflection plate via screws; ceramic heat insulation cushion blocks are arranged between the electric heating wires and the specular reflection plate; the armored electric heating wires form a barrel heating zone and heating planes at the two end parts; each of the heating planes at the two end parts is a heating zone; the barrel heating zone is divided into three heating zone parts; and each heating zone part is powered on independently and controlled individually. According to the device, five independent temperature control zones are divided on the device for stand-alone component testing devices with different contours and sizes, each zone has an independent PID (Proportion Integration Differentiation) regulation parameter corresponding to different temperature control points, and can achieve better temperature uniformity. The device has a smaller shielding rate for a heat sink, and effectively increases heat exchange area of a wall surface of the heat sink for a test product in a cooling process.
