Advantage of HSWG drying method
- An eco-friendly drying method as it does not use fossil raw materials, which are the main causes of air pollution and global warming.
HSWG actual use Data (for high-temperature 180℃)
■ Time to reach target temperature (180℃)
- 10 minutes after system operation
■ Time to retain target temperature (180℃)
- 20 minutes, specify drying time
■ Upper, middle, lower temperature deviation
- Within -5℃
■ Comparison of painted product temperature and atmospheric temperature
- Painted product temperature is higher by 30℃ or more
Technical difference between Heat Spreader module and other far-infrared ray heaters
1. Applied radiation conversion materials
Based on the radiation items in the table above, radiation is proportional to the cross-sectional area of the heat transfer part and four times the heat transfer temperature.
Heat transfer temperature
Hit Spreader module: (400 + 273.15)/100 to 4 square (or ((400+273.15)/100)4 is about 2,053
Existing far-infrared heating: (400 + 273.15) / 100 to 4 square (or ((400+273.15)/100)4 is about 123
Heat Spreader module has 16 times or more radiation
Considering the cross-sectional area and heat transfer temperature, the radiation amount is 32 times or more that of existing far-line heaters
b : Distance between heat transfer sections
A : The cross-sectional area of the heat transfer or the contact area of the fluid by supplying heat energy
A0 : Cross-sectional area of water heat pump
a : Heat transfer coefficient
ε : Emissivity of heat transfer
ε0 : Radiation of water heat pump
T : Heat transfer temperature
T0 : Water hydrothermal temperature (4.88 is an integer in dimension ()) (
Nuclear terminology dictionary
Substance emits energy from electromagnetic waves in response to temperature.
This is called radiation. Metal radiation is caused mainly by motion of electrons and has a short wavelength emission peak of less than 1㎛.
In non-metals, such radiation is caused by vibration of molecules, atoms or lattice, where emission rate is high in long-wavelength and the amount of energy created is high.
Solid and liquid radiation is a continuous spectrum, but in gas it is a discontinuous bright-line spectrum.
The total radiant energy E generated from a unit surface of an abnormal object of a black body, which fully absorbs incidental radiation, is proportional to the square of the absolute temperature of the surface and is expressed as E = σT4, where.
σ is the Stefan-Boltzmann constant and its value is 5.67×10-8 W/m2K4.
The radiation of an actual object smaller than a black body. There are many objects that use E = εσT4, which is called a gray body. ε(<1) is called emissivity.
