Forced-air cooling for station cables

Electrical Engineering, 1951
In modernizing older existing stations in connection with plant capacity addition programs, difficulties often are encountered in installing adequate generator outlet capacity for modern generators several times larger in rating than the older units being replaced.

Forced Air Cooling of Packaged Strawberries

2003, Las Vegas, NV July 27-30, 2003, 2003
To avoid decay of strawberries, it is important to cool strawberries quickly after harvesting and to maintain refrigerated conditions during distribution. In recent years, one-pound clamshell containers with hinged lids have replaced many of the open-top pint containers. In addition, there is an increased retail demand for a standardized larger tray

Forced air cooling of open hearth roofs

Refractories, 1972
Using rig equipment a study was made of the temperature distribution across the thickness of a 460 mm periclase-spinel roof in an open hearth furnace in conditions of natural cooling, and also forced surface and deep cooling of the structure.

Study on Forced-air Pre-cooling of Longan

2007 Minneapolis, Minnesota, June 17-20, 2007, 2007
As the first operation in the cold-storage chain, pre-cooling is a key component in the modern circulation system of fruits and vegetables. A forced-air pre-cooling experimental device was established for researching temperature characteristic of Longan pre-cooling process.

Forced-air Cooling Packaged Blueberries

Applied Engineering in Agriculture, 1996
Harvested blueberries, packaged in plastic covered 0.47-L (1-pt) fiber cups, arranged 12 cups to a corrugated master and palletized (96 masters to a pallet) were cooled with forced-air pulled horizontally through the stack. Air flow rates varied from 0.0011 to 0.0022 m3/s/kg (1.06 to 2.12 cfm/lb) of fruit.

Forced Air Cooling With Synthetic Jet Ejectors

Advances in Electronic Packaging, Parts A, B, and C, 2005
This paper discusses the concept of synthetic jet ejectors for forced air cooling and some practical implementations of the same. Synthetic or “zero-mass-flux” jets, unlike conventional jets, require no mass addition to the system, and thus provide means of efficiently directing airflow across a heated surface. Because these jets are zero net mass flux

Forced-Air Cooling of Bell Peppers in Bulk

Transactions of the ASAE, 1977
ABSTRACT TEMPERATURE response, as a function of air velocity and position in load, was determined during cooling of bell peppers in bulk with 1.7 °C (35 °F) air. Data were analyzed to provide graphs and equations that can be used to predict mass average tempera-tures during cooling for any desired initial product temperature or cooling air temperature,

Thermodynamics analysis for forced air pre‐cooling of cherry

Journal of Food Process Engineering, 2021
AbstractForced air pre‐cooling after harvest of fruit was an indispensable part of modern cold chain logistics. A comprehensive thermodynamics evaluation system of forced air pre‐cooling for cherry was established in this paper using the finite volume method and verified with experimental results.

Heat transfer analysis of air cooling in forced air and forced convection PEM fuel cells

2012 International Energy and Sustainability Conference (IESC), 2012
The optimum operating temperature of a Polymer Electrolyte Membrane (PEM) fuel cell is approximately 80°C. The electrochemical reaction inside a PEM fuel cell stack produces approximately 50% of electrical and 50% of heat energy. The power output of the fuel cell stack is significantly influenced by the humidity and temperature inside the power stack ...

Forced-oil forced-air cooled transformer problems

Electrical Engineering, 1951
THE ADOPTION of forced-oil forced-air cooling for large power transformers by the electrical 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.
