In the 45RFE applications four gears are utilized. In the 545RFE four gears are used on the upshift and a new "gear", 2nd Prime, was used with a different (1.50:1 rather than 1.67:1) ratio to increase versatility when downshifting. Although, with some tuning, you can get the 545RFE to upshift into 2nd Prime. [2]
Generic supplemental/spot cooling techniques, as well as turnkey cooling solutions developed by equipment manufacturers are viable solutions. Such solutions could allow very high heat release equipment to be housed in a central office that has a heat density at or near the cooling capacity available from the central air handler.
Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components.
A sudden fail-open fault can cause multiple secondary failures if it is fast and the circuit contains an inductance; this causes large voltage spikes, which may exceed 500 volts. A broken metallisation on a chip may thus cause secondary overvoltage damage. [1] Thermal runaway can cause sudden failures including melting, fire or explosions.
A thermal fuse is used when the overheating is a result of a rare occurrence, such as failure requiring repair (which would also replace the fuse) or replacement at the end of service life. [ 1 ] One mechanism is a small meltable pellet that holds down a spring.
Overheating may refer to: Overheating (economics) , a rapid, very big growth of production that is thought to have a negative influence Overheating (electricity) , unexpected rise of temperature in a portion of electrical circuit, that can cause harm to the circuit, and accidents
Joule heating is caused by interactions between charge carriers (usually electrons) and the body of the conductor.. A potential difference between two points of a conductor creates an electric field that accelerates charge carriers in the direction of the electric field, giving them kinetic energy.
The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance, and the specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material. Heat capacity is a physical property of a substance, which means that it depends on the state and properties of the substance under ...
