Information

Outdoor cabinet refers to the equipment which is directly under the influence of natural climate and is made of metal or non-metal materials and does not allow unauthorized operators to enter the cabinet. It provides outdoor physical working environment and security system for wireless communication stations or wired network station workstations. Suitable for outdoor environment, such as road, park, the roof, the mountains, the ground installation cabinet, cabinet can be installed base station equipment, power equipment, storage battery, temperature control equipment, transmission equipment and other auxiliary equipment, or equipment installation space reserved for above and in heat capacity, can provide reliable mechanical and normal operation of the internal device cabinet of environmental protection.

Outdoor cabinet is divided into heat exchange type and semiconductor temperature control type. The heat exchanger is used as the temperature control element of the heat dissipation equipment, and the heat dissipation method of transferring heat through the heat exchanger core isolated from each other is made use of the completely isolated air duct inside and outside. The choice of heat exchanger should be based on the calorific value of the equipment inside the outdoor cabinet. The semiconductor equipment is used to actively refrigerate the temperature in the outdoor cabinet cabin. Considering the application of outdoor harsh conditions, the compressors without semiconductor refrigeration is beneficial to provide the reliability of the refrigeration system. This kind of constant temperature outdoor cabinet is widely used in the centralized procurement of China Unicom, Mobile and Telecom operators.

It is used to manufacture the plates outside the outdoor cabinet. The thickness of the hot dip zinc plate is greater than or equal to 1.5mm. The hot dip zinc plate shall be sprayed with outdoor powder after welding. Thermostat parts for the heat dissipation type of the cabinet using hot dip zinc board for the board, temperature controller parts for refrigeration type of cabinet using greater than or equal to 1.5mm hot dip zinc board plus 10mm insulation cotton structure for the board. The base of the outdoor cabinet machine is made of cold-rolled steel plate with a thickness of no less than 2mm, which is processed by hot dip zinc after welding. Metal materials used in cabinets, with or without surface treatment, shall be resistant to corrosion and electrochemical reactions. Non-metallic material parts (including insulated wires, cables and foamed materials) should be flame retardant materials, the combustion of which should be able to pass the flame retardant test requirements.

Manufacturing process of outdoor cabinet:

Appearance: the surface of the coating should be continuous and uniform, and the texture should be consistent with the corresponding standard template, and there should be no nodulation, shrinkage, blistering, pinhole, cracking, peeling, pulverization, particles, hanging, exposed bottom, inclusion of dirt and other defects. For the cabinet without spraying treatment, the gloss and texture of the outer surface should be uniform and beautiful.

Adhement force: the coating on the surface of outdoor cabinet meets the requirements of grade 1 in table 1 of GB/T 9286-1998 after adhesion test.

Impact resistance: after impact resistance test, the coating on the surface of outdoor cabinet has no radial cracks, notches and other defects.

Anti-aging: anti-aging coating on the surface of outdoor cabinet.

Solvent resistance: after solvent resistance test, the coating on the surface of the outdoor cabinet should not lose light, obviously fade and appear signs of being wiped.
