Abstract
Natural convection liquid cooling of simulated electronic components in a vertical channel was investigated. The test surface consisted of three columns of fifteen flush mounted foil heaters. The channel was formed by placing a smooth movable shrouding wall parallel to the test surface. The experimental procedure called for temperature measurements and flow visualization at various power levels and channel spacings. Surface temperatures of each heat source were measured using a centrally located embedded thermocouple. Temperature measurement within the flow was conducted using a thermocouple probe. Flow visualization was conducted with the use of a laser generated plane of light. A visual temperature profile of the board was developed through the use of liquid crystals. From the data obtained, experimental correlations relating the local heat transfer properties with shroud wall spacing and strip heater power levels were developed.
