Chassis cabinet is a cabinet processed by sheet metal processing equipment
Chassis cabinet refers to a cabinet processed by sheet metal processing equipment (laser cutting machine, foaming machine, CNC punching machine, bending machine, etc.). Chassis cabinets are widely used in various fields. Nowadays, manufacturers are not just processing chassis cabinets. Some manufacturers have begun to do their own wiring and power distribution. All-round development is the way for enterprises to survive.
Chassis cabinets have three functions
First, it provides space for power supply, motherboard, various expansion boards, floppy disk drive, optical disk drive, hard disk drive and other storage devices, and fixes these parts firmly inside the chassis through the support, bracket, various screws or clips and other connectors inside the chassis to form an intensive whole. Secondly, its solid shell protects the board, power supply and storage equipment, can prevent pressure, impact and dust, and it can also play the role of anti-electromagnetic interference and radiation, and shield electromagnetic radiation.
Thirdly, it also provides a lot of easy-to-use panel switch indicator lights, etc., so that the operator can more conveniently operate the microcomputer or observe the operation of the microcomputer. We understand the chassis and cabinets, and let the chassis and cabinets serve us well.
Judging the quality
The quality of the chassis and cabinets is directly affected by the quality of the manufacturing process. The steel plate edges of the chassis with higher technology will not have burrs, sharp edges, burrs, etc., and the exposed corners are folded, which is not easy to scratch the installer's hands. The positioning of each card slot is also quite accurate, and there will be no embarrassing situation that the accessories cannot be installed or misplaced.
1. Look at the steel plate. The steel plate must be thick. You can feel which ones are thick and which ones are thin by knocking with your fingers.
2. Look at the spray paint. For a qualified cabinet, all steel materials need to be sprayed, and the spray paint must be even, so that it can be well rust-proof and dust-proof.
3. Look at the structural layout. Generally speaking, there should be more baffles and heat dissipation holes. Some iron sheets used to fix cables should be wrapped to prevent damage to the cables. The side wall fan should be installed on the back wall of the cabinet, because most of the heat is generated at the back of the equipment.
4. Check the accessories. Since the installation includes network cables, telecommunications cables and power cables, you need to buy hook-and-loop straps or toothed straps to effectively and orderly fix the cables in the cabinet. If the cabinet has a cable management module so that the cables can be directly fixed in the vertical mounting rail, it is even better.
5. Check the glass. The glass must be thicker. Also pay attention to whether there are cracks around the glass. If there are cracks, it means there are hidden dangers. Also pay attention to whether it is tricky.
