Description

The invention relates to a modular autonomous thermo-vibro-insulating system for critical equipment and products usable in mobile data center systems and technologies ("mobile data center") and designed to protect critical information systems and ensure optimal operating conditions. of them, regardless of the exposure situations.

Possible applications of the invention in mobile data centers are:

Command centers of government institutions;

- Emergency interventions in the event of disasters and natural disasters, in which the entities are required to carry out activities in mobile units;

Disaster relief humanitarian centers;

Scientific research activities in remote areas;

- Industrial activities in harsh areas of operation;

- Emergency medical centers;

- Marketing activities carried out in exhibition centers or in traveling exhibitions;

From the prior art it is known that data centers are composed of IT equipment (servers, switches, routers, data storage, etc.) that are usually enclosed in dedicated buildings or containers. Mobile data center applications require relocation of IT equipment to different geographical areas and climatic areas. Moreover, in order to be able to withstand the mechanical and climatic stress conditions (shocks, vibrations, low or high temperature, saline or dust / rain conditions, freeze-thaw, lower pressures specific to air transport), the equipment intended for such applications is performs in rigid or semi-rigid conditions. On the relocation site, information systems are deployed in temporary locations, containers or non-permanent premises. Moreover, in the case of applications involving the physical security of the information transmitted, electronic equipment, connectivity, cables, terminals are secured by electromagnetic shielding (EMI / EMC). As a rule, the shielding is performed at the equipment level and in this way the security is achieved. However, it is known that such an intervention on the equipment leads to high cost prices (which increase the value of the equipment more than 3 times).

Boxes with rack-able IT equipment (TC1, TC2, TCn) and which are the object of the invention;

- ACU air conditioners, coupled to TC boxes with return and return air bags;

- Workstations 1,2, ... n or process stations.

The IT equipment transport box is made in a classic configuration, respectively a box body (1), closed at the two ends with two caps, a front cover (2) and a back cover (3). Inside the box is a shielded rack (4) that houses the electronic equipment (EE) and is mounted to the body of the box (1) by means of 8 shock absorbers (5) arranged in a diagonal configuration (the front and rear sections of the rack). acquis). The body of the box is sealed at the front with the CP panel (13) and the removable panel (6) fastened to the locks (8) and at the back with the power connector panel (10), the communications connector panel (9) and with air conditioning panel (7). The air conditioning panel has two air vents, an air intake hose (11) and a discharge hose (12) and the locks (8) that secure the panel to the box when needed. The box body is provided with a humidity indicator (14) for the purpose of visualizing the approximate level of humidity inside the box during transport and storage and an automatic pressure valve (15) for equalizing the pressure between the atmosphere and the inside of the box. This creates a sealed environment inside the box, free of impurities or moisture, with two workspaces, one inside the rack (A) and the other (B) between the rack and the body of the box.

The rack (4) is made in shielded construction (TEMPEST). The rack is composed of a resistance structure (16), provided with shock absorber supports (17) and closed with panels (18) on the sides of the rack, the front panel (25) and the rear panel (19). Electromagnetic sealing is achieved with elements that are mounted on the panels, respectively, the wave filters (20) on the back, (26) on the front and (21) on the top panel. Power supply filters, redundant (22), filters for data connections (23), and waveguides (24) are also attached to the panels. The waveguides allow the fiber optic cable strands to pass through, while the data filters transfer the information from inside the rack to the outside of it to the CP (monitoring equipment operation and environment mode) and allow setting the parameters of the environment module.

The equipment (ΕΕ) inside the transport box remains permanently mounted in the transport box.

The configuration thus achieved, achieves several statuses:

A. State of transport and storage. In this state, the boxes have the lids fitted. For transport, the shielded rack is prone to shock absorption. The box is a watertight barrier to external factors (dust, humidity, rain, salt fog, etc.). Inside the box or rack, a desiccant cartridge is inserted to keep the internal humidity below 60%.

B. Operating status. In this state, the box covers are removed, the box is connected to the power source via the connectors on the power connector panel (10), the connection to the data network via the data connectors (fiber optic) (9) and the module The environment (27) monitors the internal parameters (temperature and humidity) in the shielded rack space (A). 3 operating modes are possible in the operating state:

a. in protected environments (enclosures devoid of dust, salinity, and at normal temperature); In this case, the transport box is placed in the operating environment (without caps) and the connections to the networks made, and the removable panels extracted. The equipment (EE) operates in normal mode, the internal ventilation absorbs air at the temperature of the storage compartment through the wave filters (26) and (21) and discharges it through the back through the wave filter (20), taking on the specific heat of the operation;

b. in low temperature environments; In this case, in order to be able to put on the equipment, a preheating sequence is required up to a minimum working temperature, specific to each equipment. When supplying the power box, the environment module notices the low temperature, does not start the equipment and only the heating system, composed of the package of centrifugal fans (28) and the resistive heating element (29). Inside the rack in space (A) a heated airflow is created which washes the equipment (EE), heats up the rack and partially the space (B). The preheating temperature and time control is performed by the environment module (27). When the preheating sequence is completed, it notifies the control center and is ready to start the equipment. During the preheating sequence, the air inlet and outlet ports in the air conditioning panel are closed by <2015-- 007662 8 -10- 2015, the plugs (30) and (31) - respectively intake and discharge. After the preheating sequence, depending on the external environment, it is decided the start of the equipment and the operation in normal or cooled air conditioner operation.

c. in environments with high temperature and / or humidity; When connecting the box to the power and data network, the environment module communicates to the control center the temperature / humidity status inside the rack and the operating regime - the one with air conditioning is decided. Remove the plugs (30) and (31) and on the ends of the airbags (11) and (12), insert flexible hoses that bring a supply of cooled air to the temperature of 10 .... 25 ° C, with the unit of 10 -15% and with a similar or higher flow rate than the equipment. Thus, through section (C) a cold air supply takes place in space (B), the flow of which flows at the top towards the front section of the box, where, due to the depression formed at the front of the equipment, the cold air is sucked in. by the wave filters (26) and (21) in space (A) by the equipment. It discharges it through the back side through the wave filter (20), taking the heat specific to the operation; The hot air discharged from the ventilation of the equipment is taken over by the return hose (12) through its section (D) and transmitted for reprocessing (cooling) of the air conditioning system that must be produced in a sealed room, in the absence of dust or moisture.

d. If the starting temperature of the equipment is lower than the internal temperature of the rack, the environment module notifies this state and does not allow the starting of the equipment until after a prerecording sequence has been performed. When the temperature in space (A) reaches a value that allows the operation of the equipment, the environmental module allows the supply of the equipment (EE) and the operation with air conditioning.

We consider the modular autonomous thermo-vibro-insulating system for critical equipment and products usable in the systems and technologies of mobile data center type is a modem and versatile product, with multiple possibilities of use in different geographical areas and climates.
