Optical fiber communication high temperature aging room is widely used in aging test of power electronics, computers, communications, biopharmaceuticals and other fields. It is a high temperature and harsh environment test equipment for high performance electronic products. It is an important experimental equipment to improve product stability and reliability. It is also an important production process for enterprises to improve product quality and competitiveness. What are the factors that affect the price of the aging house? First, the size of the room (the size of the room determines the type of fan, the number of fans, the size of the duct) 通常市面有轴流风机、离心风机、风柜来制作
Usually there are axial flow fans, centrifugal fans and air cupboards on the market.
The centrifugal fan is installed on the top of the high temperature aging room of optical fiber communication, and then the corresponding number of air ducts is designed according to the power of the fan and the size of the room. Each air duct is connected to the bottom of the room. Two double-layer louver outlets are installed on each air duct, and the outlet can adjust the direction of the air outlet. Then the air is circulated from the top return air outlet. Centrifugal fans are used in ageing rooms which are not very large in general.
Axial flow fan is installed on the top of high temperature aging room of optical fiber communication, and the corresponding shutters are installed on the ceiling according to the number of fans. The concept of return air on the upper outlet is adopted. This method has low cost and low controllability of temperature uniformity, because the hot air is from the bottom to the top.
Windshield is mainly optical fiber communication high temperature aging room room room is too large, span is too wide, temperature uniformity requirements are too high, if the room is large, the number of vertical fresh fans will increase correspondingly, the noise will be very large. The cost is very high.
Second: Temperature range (different materials are selected for different temperature range)
Usually, there are two kinds of materials for high temperature aging room of optical fiber communication: EPS color steel plate and rock wool color steel plate. Color steel plate is mainly used for aging at room temperature to 60 degrees. EPS color steel plate, commonly known as foam board, is not flame retardant. It does not meet the requirements of grade B2 for classification of combustion properties of building materials. There is no problem in long term usage below 60 degrees.
Rockwool coloured steel sheet is flame retardant at ageing temperature above 60 degrees, which meets the requirements of Class A of Combustion Performance Classification of Building Materials.
In addition, there is also a polyurethane color steel plate on the market, its maximum temperature resistance is 85 degrees, flammable, if burned, there are harmful gases generated, only professional companies use this material, and the cost is expensive.
Thirdly, the products that need to be aged and the power of the products (the difference of the products involves whether the products are heated or not, and the power involves the configuration of the power supply inside).
Power of aging products: In the high temperature aging room of optical fiber communication, power supply for the aging frame of products is needed. Power involves the size and quantity of wire rods. If the heating of products involves the use of civil or military wire rods.
IV: Temperature uniformity requirements
The temperature of high-temperature aging room of optical fiber communication is generally 40 degrees (+1 C), 50 degrees (+3 C), 60 degrees (?)
If the uniformity of above 60 C is too high, it can be controlled by PLC or by the way of parent computer.
Fifth: The temperature point of aging and the total power of products (related to the exhaust system, exhaust is based on the size of the room temperature range and the power of the product to find a constant temperature point, when the product heating is too high, the exhaust fan runs to ensure that the temperature is controlled at the set temperature)
The common temperature point of high temperature aging room of optical fiber communication involves exhaust air system. According to the total power (heating power) of products in high temperature aging room of optical fiber communication, the power of exhaust fan and the size of exhaust duct can be calculated by corresponding formula according to a certain temperature.
