The aluminum alloy formwork is made of aluminum alloy profiles as the main material, which is suitable for concrete engineering made by machining and welding processes, and is designed according to the 50mm modulus. The device is assembled. The design and construction application of aluminum alloy formwork is the innovation of concrete engineering formwork technology, the promotion of prefabricated concrete technology, and the embodiment of the industrialization of construction technology. aluminum mold casting,aluminum mold making,aluminum and mold,aluminum mold base Sung Precision Mould & Plastic Co., Ltd. , https://www.injectionmoldingfactorys.com
Radiator is the radiator heating the surrounding air, and then the hot air rises and flows away. The cold air continues to flow and is heated again. This endless circulation creates air convection and transfers the heat of the hot water in the radiator to the room. If the radiator is closed by the heating hood, air convection cannot be formed, and it is difficult for the radiator to release heat by convection. In addition, because the surface temperature of the radiator is higher than the temperature of the indoor object, the hot surface of the radiator continuously emits heat radiation to the surrounding objects and the wall to heat the room. The heat radiation is performed in a straight line. If the heat sink is covered, the heat of the heat sink can only be radiated to the inner surface of the cover, and then the secondary radiation is conducted through the outer surface of the heating cover, and the radiant heat is greatly reduced. In this way, the room is not hot, because the room is not getting heat before the heating hood.
In order to make the room beautiful, people usually install the heating cover when the house is renovated. After adding the heating cover, people find that the room is much colder than in the past. Why is this?
