General
- Radiators and convectors are types
of heat exchangers designed to transfer thermal energy from one medium
to another for the purpose of cooling and heating.
- In automobiles with a
liquid-cooled internal combustion engine a radiator is connected to
channels running through the engine and cylinder head, through which a
liquid (coolant) is pumped.
- The radiator transfers the heat
from the fluid inside to the air outside, thereby cooling the
engine.
- A car’s radiator, usually made of
an aluminum tube, is bent into several folds to form a rectangular
shape. The purpose of this design is to maximize the surface
area.
Application
- A typical ESPAR antenna consists
of monopole or dipole elements, one of which is the radiator (fed
element) and the others are the parasitic radiators with variable
reactance devices loaded on them. It can provide a lower-cost solution
as an adaptive array antenna or angle diversity antenna, since it needs
only a single receiver circuit.
- Electrostatically switched
radiator (ESR) is a device that can control the radiation emitted from a
surface by controlling the position of a thin membrane.
- The ESR device can be use to
control thermal radiation emitted from a surface and can be treated as a
variable emittance device
- The electron beam through thin
targets can remarkably increase the efficiency of x-ray production
without significantly changing its spectral and angular
distributions.
- The application of liquid sheet
radiator is evaluated on the effects of dust propagation, system cost,
specific power, overall weight, and efficiency.
Technology
- Time-modulated ultra-wideband
systems is the technique applied to similar emissions from unintentional
radiators.
- Time-modulated ultra-wideband RF
transmissions, the technique that is most faithful to this objective is
to use the existing intentional radiator technique for non-pulse
modulate sinusoid carrier emissions.
- Radiator Warehouse is the
technology for recycling water and reducing chemicals.
- The UWB radiators are used in a
radar technology of high spatial resolution and for checking of
electromagnetic compatibility.
Report
- In manufacturing the radiators,
the CuproBraze process is used to braze the joint at the header
plate-to-core interface and to enhance the rigidity of the
fins.
- The high conductivity graphite
foam presents a unique solution to the increasing cooling demands of
power electronics and other automotive components.
- Exposure of radiation can be
controlled through the proper design, installation, use, and maintenance
of a ventilation system that moves the contaminated air away from the
worker's breathing zone.
- L&M’s small radiators start at
$400, while the radiators sold to Terex typically run from $25,000 to
$30,000 delivered (the radiator for Terex’s
smallest truck costs
$15,000).
Market
- Rettig plans to introduce another
production line into the Tianjin factory, which will have an annual
manufacturing capacity to produce 350,000 panel radiators.
- The 1-800-Radiator computer system
has a proprietary "stocking mechanism" in its software which helps fine
tune each and every market to have a unique inventory mix.
- The market for towel
rails/bathroom radiators is increasing at over 8% per annum across the
five Western European countries studied.
- Italy is overwhelmingly dominates
the cast iron market, however, the market is expected to decrease due to
the popularity of more modern and practical tubular multicolumn
radiators.
- The Italian radiator market is
fragmented with most of sales being covered by local
production
