There are many ways to increase the heat dissipation of LED displays . When dissipating heat, depending on the power level and the place of use, there will be different considerations. The following is introduced from eight aspects.
1. Air hydrodynamics, using the shape of the lamp housing to create convective air, which is the lowest cost method to enhance heat dissipation.
2. The fan dissipates heat, and the inside of the lamp housing uses a long-life and high-efficiency fan to enhance heat dissipation. The commonly used method has low cost and good effect.
3, the use of aluminum fins, this is the most common way to dissipate heat, using aluminum fins as part of the shell to increase the heat dissipation area.
4, the surface radiation heat treatment, the surface of the lamp shell is radiated and heat-dissipated, the simpler is to apply the radiation heat-dissipating paint, which can be carried away from the surface of the lamp shell by radiation.
5, the heat pipe heat dissipation, using the heat pipe technology, the heat is led from the LED display chip to the shell heat sink fins. This method is also used on large luminaires such as LED street lights.
6. The heat-conducting plastic shell is filled with the heat-conducting material during the injection molding of the plastic shell, thereby increasing the heat-conducting and heat-dissipating ability of the plastic shell.
7. Using a liquid bulb encapsulation technique, a transparent liquid having a high thermal conductivity is filled into the bulb of the lamp body.
8, heat conduction and heat dissipation integration - the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp housing is to reduce the operating temperature of the LED display chip, because the LED chip expansion coefficient and our common metal heat conduction, heat dissipation material expansion coefficient is very large, can not The LED chip is directly soldered to prevent high and low temperature thermal stress from damaging the chip of the LED display.
Effectively improve the heat dissipation of the LED display can save power and improve the service life of the LED display.
Deluxe Rice Cooker
Deluxe
Rice Cooker was one of electric type rice cooker , but it`s the most popular type of electric
rice cooker . especially famous in Southeast Asia area with its good
appearances with various functions. Not only its outer shell could be
customized with different demands, but also it speeding cooking , saving times and electricity, enhancing our
lifestyle
Features
The
inner pot is made of solid and durable aluminum alloy of high intensity , such as non-stick inner pot , stainless
steel inner pot and honeycomb patterned inner pot with non-stick coating.
There are some models that use stainless steel instead of
aluminium .Various other materials, such
as copper, pure carbon, ceramic, and diamond powder coating, may be used for
higher heat conductivity or better taste.
Applications
Multifunction , can cooking rice, soup and much
more. added cooking versatility with supplied steam tray.
Some rice cookers have settings for congee, a type of
rice porridge called okayu in
Japanese, Juk in Korea, and zhou in Chinese.
More elaborate recipes are possible using a rice cooker, and there
are cookbooks devoted entirely to dishes prepared using a rice cooker. It is possible to cook soups, stews or
sponge cakes in electric rice cookers. By
simply adding ingredients and setting it to "warm", a rice cooker
cooks the contents at about 65 °C (150 °F). In a few hours, the stew is fully
cooked and ready to eat.
