COMMERCIAL-SCALE FORCED-AIR COOLING OF PACKAGED STRAWBERRIES
Transactions of the ASAE, 2004Strawberries are an extremely valuable crop, but they are also very sensitive to decay if not cooled and maintained at proper temperatures. Strawberries are typically packaged in the field and quickly transported to a cooling facility, where they are precooled by forcing cold air through the vents of the packaging.

Active noise control in a forced-air cooling system
Control Engineering Practice, 2010Active noise control Feedforward control Parameter estimation Digital filters Control applications a b s t r a c t This paper discusses the design methodology for the active noise control of sound disturbances in a forced-air cooling system. The active sound cancellation algorithm uses the framework of output-error based optimization of a linearly ...

Suction vs. Pressure Forced Air Cooling
IEEE Transactions on Product Engineering and Production, 1965The cooling of miniaturized equipment is usually handled by forced air flow. An investigation was made of the merits of suction vs pressure cooling, to find an effective cooling design for a certain module assembly. This showed that suction cooling has certain advantages because of the air flow escape from the circuitry section to adjacent spaces.

The increasing demand in subminiaturization and microminiaturization of electronic equipment has inevitably brought about increases in component and package densities. “Natural” cooling (heat sinks, free-air radiation, and natural convection) is no longer adequate for maintenance of operating temperatures within safe, or optimum, ranges.

Thermal management and forced air-cooling of supercapacitors stack
Applied Thermal Engineering, 2015Abstract The main objective of this study is to investigate heat transfer inside and around a supercapacitor stack. The crossflow staggered arrangement with five rows was also studied for different transverse and longitudinal pitches. The mathematical model governing the problem is numerically solved in a three-dimensional computational domain using ...

The effect of alternating ventilation on forced air pre-cooling of cherries
International Journal of Food Engineering, 2020Abstract Large temperature gradients caused by the traditional forced air pre-cooling method leads to the decrease of the shelf life of horticultural products. An alternating ventilation of air pre-cooling is one of the key methods to reduce the temperature inhomogeneity of cherries. The research results on the alternating ventilation

Forced Air Cooling of Shape-Memory Alloy Actuators for a Prosthetic Hand
Journal of Computing and Information Science in Engineering, 2016This research paper presents the development of nonconventional actuation technology for use in a prosthetic hand. Shape-memory alloy (SMA) is used for the actuation. SMA is a material which contracts when heated and relaxes when cooled and has a work density 25 times greater than traditional electric motor actuators.

Forced-air cooled strontium-ion recombination laser
Optics Communications, 1991Abstract The performance of a small (12.6 mm bore) Sr + discharge-afterglow recombination laser (λ 430.5 nm) is assessed with free convection cooling of the laser tube, and with forced-air convection cooling. It is found that the application of forced-air cooling enables a 120% higher input-power loading for optimum tube-wall temperature, that ...

The practical limits of forced-air cooling of electronic equipment
Conference Proceedings., Eleventh International Telecommunications Energy Conference, 2003Cooling with forced air is analyzed from a general perspective. It is demonstrated that there are physical processes that limit the maximum dissipation of heat from a frame or shelf of electronic equipment. These constraints are shown to arise from the limitations on allowable acoustic noise.
