DETAILED DESCRIPTION

Referring to FIG. 1, a container data center in accordance with an exemplary embodiment is shown. The container data center includes a container 10, a plurality of servers (not shown) mounted in the container 10, and a ventilating system 20 for dissipating heat of the servers.

The ventilating system 20 includes a filter 30, an inlet pipe 50, an exhaust pipe 70 and a fan (or blower) 90. The fan 90 is adapted for driving ambient cooling air through the filter 30 to the container 10, during which process the ambient cooling air is purified. In this embodiment, the fan 90 is fixed on the container 10. An inlet of the fan 90 is coupled to an outlet of the exhaust pipe 70, and an outlet of the fan 90 is coupled to the container 10. In alternative embodiments, the fan 90 can be arranged at an inlet of the inlet pipe 50. In such state, the inlet of the fan 90 faces the ambient while the outlet of the fan 90 is coupled to the inlet pipe 50.

The filter 30 includes a chamber 40 receiving filtering fluid 34 therein. The filtering fluid 34 is used to dissolve the dust in the ambient cooling air. In this embodiment, preferably, the filtering fluid 34 is pure water.

The chamber 40 defines an air inlet 420 and an air outlet 422 in a top side 42 thereof, for respectively connecting the inlet pipe 50 and the exhaust pipe 70. The air inlet 420 and the air outlet 422 are located adjacent to two opposite sides (left side 44 and right side 46 in FIG. 1) of the chamber 40, respectively.

A protrusion 49 extends down from a central portion of the top side 42 of the chamber 40 towards a bottom side 48 of the chamber 40. The protrusion 49 is higher than the bottom side 48 of the chamber 40. An inlet channel 41 is formed between the protrusion 49 and the left side 44 of the chamber 40, and an outlet channel 43 is formed between the protrusion 49 and the right side 46 of the chamber 40. The inlet channel 41 is aligned with the air inlet 420 of the chamber 40, and the outlet channel 43 is aligned with the air outlet 422 of the chamber 40.

A fluid inlet 440 is defined in a lateral side of the chamber 40 for injecting clean filtering fluid 34. In this embodiment, the fluid inlet 440 is formed in the left side 44 of the chamber 40, and is lower than the protrusion 49. Alternatively, the fluid inlet 440 can be higher than or at the same level as a bottom of the protrusion 49. A fluid outlet 460 is defined in one lateral side of the chamber 40 for exhausting polluted filtering fluid 34. In this embodiment, the fluid outlet 460 is formed in the right side 46 of the chamber 40, and is adjacent to the bottom side 48 of the chamber 40. In alternative embodiments, the fluid outlet 460 can be formed at the bottom side 48 of the chamber 40.

A plurality of baffles 47 is formed in the outlet channel 43 of the chamber 40, for further obstructing the dust in the ambient cooling air. The baffles 47 can be plastic or steel, and can be integrally formed with the chamber 40 as one monolithic piece. In this embodiment, the baffles 47 extend obliquely down from the right side 46 of the chamber 40 and from a side of the protrusion 49 facing the outlet channel 43, in an alternate manner. The baffles 47 overlap partly in a center of the outlet channel 43.

When the container date center is in use, the inlet pipe 50 is connected to the air inlet 420 of the chamber 40, and the exhaust pipe 70 is connected to the air outlet 422 of the chamber 40. The fan 90 is disposed with the inlet thereof coupled to the exhaust pipe 70 and the outlet thereof coupled to the container 10. The filtering fluid 34 is injected into the chamber 40 through the fluid inlet 440. An amount of the filtering fluid 34 injected into the chamber 40 should be controlled with a liquid level thereof lower than the protrusion 49. Thus a gap 45 is formed between the protrusion 49 and the filtering fluid 34 for flowing of the cooling air from the inlet channel 41 to the outlet channel 43.

During operation of the servers, heat is generated. The fan 90 operates to drive the ambient cooling air through the ventilating system 20 to the container 10 to cool the servers. After the cooling air enters the chamber 40 of the ventilating system 20 via the air inlet 420, the cooling air flows down along the inlet channel 41 towards the filtering fluid 34, during which process a portion of the dust in the cooling air falls into the filtering fluid 34. When the cooling air arrives at the liquid level of the filtering fluid 34, the cooling air turns to flow along the gap 45 to the outlet channel 43. During flowing of the cooling air along the gap 45, the cooling air touches the liquid level, and thus a majority of the dust in the cooling air falls into the filtering fluid 34.

When the cooling air flows up along the outlet channel 43 to exhaust from the filter 34, the cooling air flows tortuously in the outlet channel 43 under the guidance of the baffles 47, and thus almost all of remaining dust in the cooling air falls into the filtering fluid 34. Thus, the cooling air exhausting from the filter 30 is purified. In addition, the filtering fluid 34 is prevented from being sucked out from the filter 30 by the baffles 47 arranged in the outlet channel 43 of the filter 30. Accordingly, a humidity of the cooling air exhausting from the filter 30 is minimal. Accordingly, the safety of the servers which are cooled by the purified cooling air is enhanced. In testing, the filter 30 has demonstrated that it can remove more than 99.9% of dust with a particle size not less than 0.3 μm.

In the above-described embodiment, only one filter 30 is utilized. It should be understood that plural filters can be connected in series to purify the ambient cooling air. In addition, after the ventilating system 20 has worked for a period of time, the filtering fluid 34 of the filter 30 becomes polluted to a threshold level by the dust of the ambient cooling air, and can be exhausted through the fluid outlet 460. Thereupon clean filtering fluid 34 is injected to continue purifying the ambient cooling air.

FIG. 2 shows a container data center in accordance with a second embodiment. The difference between the second embodiment and the first embodiment is a shape of a protrusion 49a of a chamber 40a of a filter 30a of the container data center of the second embodiment. In this embodiment, the protrusion 49a expands downwards, i.e., expands along a direction away from a top side 42 of the container 10. Thus, an inlet channel 41a of the filter 30a converges downwards, and an outlet channel 43a of the filter 30a diverges upwards. When the cooling air flows down along the inlet channel 41a, a speed of the cooling air gradually increases due to the converged inlet channel 41a, and thus more of the dust can fall into the filtering fluid 34. When the cooling air flows up along the outlet channel 43a, the speed of the cooling air gradually decreases due to the diverged outlet channel 43a, and this helps avoid dust and the filtering fluid 34 escaping from the filter 30a.

Referring to FIG. 3, a container data center according to a third embodiment is shown. Unlike in the second embodiment, an end surface 490 of a protrusion 49b of a chamber 40b of a filter 30b of the container data center of the third embodiment is uneven. When the cooling air flows along a gap 45b between the protrusion 49b and the filtering fluid 34, due to the uneven end surface 490 of the protrusion 49b, irregular and violent movements of particles of the cooling air are more pronounced, and there are more irregular and violent movements of the particles of the cooling air. Accordingly, more dust can fall into the filtering fluid 34, which can further purify the cooling air.

It is to be understood, however, that even though numerous characteristics and advantages of certain embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
