Advantages of industrial control chassis
Extrusion resistance, corrosion resistance, dust resistance, vibration resistance, radiation resistance.
Mainly used for occasions where the environment is relatively harsh. For example: power plants, chemical plants, mining plants, underground operations.
Industrial control chassis is generally used in the military, radio, television, its advantages are conducive to heat dissipation, has a good scalability.
Computer chassis
It is the mainframe of the computer's "house", play an important role in accommodating and protecting the CPU and other computer parts
Chassis form
1, the standard box: the shape of the microwave oven. Size in 50CMX40CMX30CM or so. Easy to fit into the home style, but can not use high-performance hardware.
2, ordinary chassis: and is to see the same, is the mainstream square press.
3, HTPC chassis: is the main chassis used in the living room. Size, shape and DVD no two, used for TV.
4, tower chassis: than the ordinary chassis to be higher than 1/2. Internal space is very large, generally enthusiasts only use.
Chassis purchase
1. Material. Good chassis front panel plastic are used is ABS engineering plastic production, strong and stable. If the plastic used in the chassis is not hard enough, or very brittle and easy to fracture, the quality is definitely a problem. Steel plate should be at least 0.8 mm or more, the material should be galvanized steel, hardness and elasticity, if the thickness is not enough or a little force can be bent certainly not a good material.
2. Workmanship. A look at the steel plate frame whether there are burrs, sharp mouth, good chassis are often wrapped, at least after polishing treatment, will not let you in the installation of the machine "bruises"; look at the chassis frame is solid and stable, the simplest way is to lift up and shake hard, if there is a wobble or even deformation, is definitely not a good thing; look at the interior production Whether professional, such as the installation of the motherboard when the chassis perforation location, size is matched, drive slot and card positioning is accurate. Four see if there is EMI contacts, that is, there are many small protrusions around the side panel. This can be a reduction of electromagnetic waves, favorable and human health. In short, the choice of computer chassis is important to look at its materials, workmanship and practicality, absolutely do not be confused by the appearance of fashion.
3. Squareness
I. There should be a USB port and 3.5 headphone port on the front. Preferably, there should also be a 1493 port and a SATA or ESATA port. Two. Minimum 4 optical ports and 4 hard disk ports. Three. Whether or not it can be mounted on the front panel, preferably. III. Whether it is easy to carry. Four. There shouldn't be any place on the chassis where things are squared off.
3. Internal. Power supply, hard disk, memory, motherboard, cpu, CD-ROM drive, sound card, network card, video card
