General formula of cooling curve for horticultural products on forced air pre‐cooling

Journal of Food Process Engineering, 2022
AbstractThe air velocity played a key role in controlling the cooling process of forced air pre‐cooling for horticultural products. However, the present general formula of cooling curve for horticultural products on forced air pre‐cooling did not reflect the influence of the air velocity on cooling rate for horticultural products on forced air pre ...

Operating Problems of Forced-Oil Forced-Air-Cooled Transformers

Transactions of the American Institute of Electrical Engineers, 1951
The adoption of forced-oil forced-air cooling for large power transformers by the electric industry has created a new problem for the operator of the equipment. The experience of this large utility has been that the supplier has not furnished a self-cooled rating for his product.

Performance measurements of a forced convection air-cooled rack

The Ninth Intersociety Conference on Thermal and Thermomechanical Phenomena In Electronic Systems (IEEE Cat. No.04CH37543), 2004
The forced air cooling rack, Tower of Cool (TOC) for the cooling of the racks in the data center was experimentally investigated and compared to a conventional raised floor cooling system (RFCS). The heat load was simulated with eleven 4U server chassis each fitted with inlet and outlet fans and an electric heater of 1 kW maximum heat output. The inlet

Forced-Air Cooling Systems

1990
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.

Forced air convection cooled CO2 waveguide laser

Optics Communications, 1977
Abstract An experimental study on a forced air convection cooled type flowing CO 2 waveguide laser having a BeO discharge tube is reported. Effective cooling of the laser gas has been achieved by a heat sink constructed of 40 fins of 22 mm outer diameter, 12 mm base diameter and 1 mm thickness.

A dynamic model of forced-air cooling for therapeutic hypothermia

Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (IEEE Cat. No.03CH37439), 2004
Induced mild hypothermia has been shown to have beneficial effects in neuroprotective and cardioprotective modes. Current methods require either improvised cooling systems or invasive techniques. In order to simplify, and thereby deliver therapy as safely and as quickly as possible, a high-efficiency forced-air cooling system has been developed.

Suction vs. Pressure Forced Air Cooling

IEEE Transactions on Product Engineering and Production, 1965
The 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.

Cooling characteristics of forced air convection in electronic cabinets

[1992 Proceedings] Intersociety Conference on Thermal Phenomena in Electronic Systems, 2003
Summary form only given. Air-cooled forced convection in vertical channels installed in electronic cabinets has been investigated experimentally and numerically. The heat transfer characteristics were determined experimentally and numerical simulation was performed using a finite-difference method for the electronic components based on the experimental

Study on forced air convection cooling for electronic assemblies

Frontiers of Energy and Power Engineering in China, 2008
The slotted fin concept was employed to improve the air cooling performance of plate-fin in heat sinks. Numerical simulations of laminar heat transfer and flow pressure drop were conducted for the integral plate fin, discrete plate fin and discrete slotted fin heat sinks. It is found that the performance of the discrete plate fin is better than that of
