Description

  The present invention relates to a server room exhaust heat diffusion system that exhausts heat from a server room without adding air conditioning equipment.

It is common practice to install a server in an office or laboratory.
Since a server generates noise, a server room is created by a small room or a partition, and the server and the server are installed in the server room to remove the noise on the business / research floor.
From the viewpoint of information protection, it is also important to lock the server room and manage the security.

Since the server generates heat, it is necessary to perform thermal management of the server room in order to prevent a server malfunction caused by a temperature rise in the server room.
However, in rental offices and the like, it is often impossible to add air conditioning equipment such as air conditioners for heat management.
In such a case, it is necessary to use general air conditioning for heat management of the work / research floor. Unlike the large work / research floor, the server room is made up of small rooms and partitions. As a result, heat accumulation is likely to occur.
If we try to deal with such a heat pool with overall air conditioning, the work / research floor where there is little load and no heat pool will be overcooled.
Further, since the server needs to be operated for 24 hours, the entire air conditioning cannot be stopped even on holidays or at night, and the large space is air-conditioned, resulting in an increase in power consumption.

  Further, even when the server room dedicated air conditioner can be added, the initial cost and the operation cost of the dedicated air conditioner are incurred.

  It is an object of the present invention to provide a server room exhaust heat diffusion system that can perform heat management by exhausting and diffusing the heat of a server room without adding an air conditioner.

The first invention of the present application made to achieve the above object is a waste heat diffusion system for a server room adjacent to a business / research floor, collecting the heat exhausted from the server and supplying the heat to the business / research floor. And a heat collecting fan for transporting together, a diffusion flow path for diffusing the exhaust heat to the work floor, and a return flow path for introducing the air of the work / research floor into the server room. A server room exhaust heat diffusion system is provided.
According to a second aspect of the present invention, in the server room exhaust heat diffusion system according to the first aspect, any one of an exhaust silencer provided in a part of the diffusion flow path and an intake silencer provided in a part of the return flow path or A server room exhaust heat diffusion system characterized by having both.
A third invention of the present application is the server room exhaust heat diffusion system according to the first invention or the second invention, wherein the back of the work / research floor is the exhaust silencer. I will provide a.

The present invention can obtain at least one of the following effects by means for solving the above-described problems.
<1> Although heat is exhausted and diffused to the work / research floor adjacent to the server room, the work / research floor is larger than the server room, so it has higher air conditioning capacity. Can be processed.
<2> Since the exhaust heat from the server room that has accumulated heat is spread throughout the large business / research floor and is handled by the entire air conditioning system, the work / research floor is not overcooled, providing a comfortable room temperature. Can keep.
<3> Even if the overall air conditioning for work / research floor is stopped at night, the heat from the server room is diffused to the work / research floor in a large space and a large amount of air. There is no sudden temperature rise in the floor and server room.
<4> Since the heat collecting fan has low power consumption, the operation cost is kept low and the influence on the global environment is extremely reduced.
<5> Since the heat collecting fan has low power consumption, it can be operated with the same UPS as the server and can cope with power outages.
<6> It is possible to construct a system that matches the local situation by arranging the heat collecting fan and selecting / combining the diffusion flow path and return flow path.
<7> By providing a silencer in the diffusion channel or return channel, the noise in the server room does not leak to the work / research floor.
<8> By returning the air of the work / research floor that has been air-conditioned as a whole, the server can be operated at an appropriate temperature, and the server will have a long service life.
<9> The system can be easily introduced and the server can be stably operated without adding an air conditioner such as an air conditioner.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1> Overall configuration.
The server room exhaust heat diffusion system of the present invention diffuses the exhaust heat of the server 1 in the server room S to the adjacent business floor W.
The server room S is a small space made up of a small room or a partition for installing the server 1.
The business floor W is a large space adjacent to the server room S including a research floor in a laboratory, a corridor, a staircase, an entrance, a warehouse, and the like in addition to a business floor in an office.
The server room exhaust heat diffusion system of the present invention collects exhaust heat of the server 1 together with air and conveys it to the business floor W, and diffuses the exhaust heat and air collected by the heat collection fan 2 to the business floor W. The flow path comprises a diffusion flow path 3 serving as a flow path and a return flow path 4 for introducing the air of the business floor W into the server room S. (Figure 1)

<2> A heat collecting fan.
The heat collection fan 2 is a combination of a necessary number of fans and is determined by the scale of the server 1. (Figure 2)
The heat collecting fan 2 may be directly attached to the ceiling (FIG. 1), or may be installed inside the server 1 (FIG. 3).
Since the heat collecting fan 2 is a combination of fans, it consumes less power and can be operated with the same UPS as the server.
Further, the heat collecting fan 2 can be introduced at a lower cost than an air conditioner such as an air conditioner.

<3> A diffusion channel.
The diffusion channel 3 connects one end to the heat collecting fan 2. The other end is an outlet 31 to the work floor W.
The diffusion flow path 3 is a duct that connects the heat collection fan 2 and the outlet 31, but when the heat collection fan 2 is directly attached to the ceiling, the space behind the ceiling can be used as the diffusion flow path 3 (see FIG. 1).
The blowout port 31 to the business floor W may be installed above the ceiling or the wall surface, or may be installed exposed in the room of the business floor W with the diffusion channel 3 as an extension duct (FIG. 4).

<4> Exhaust Heat / Diffusion to Business Floor The exhaust heat collected together with air by the heat collecting fan 2 is conveyed / diffused to the business floor W via the diffusion flow path 3.
Since the business floor W is a large space where the existing overall air conditioning is performed, the exhaust heat is diffused to the business floor W and processed by the existing overall air conditioning. Since the business floor W is a large space, the air conditioning capability is high, and the exhaust heat of the server 1 can be processed only by the remaining capacity.
By diffusing and processing the exhaust heat of the server 1 to the business floor W, the business floor W is not overcooled, and a comfortable room temperature can be maintained.
Even if the air conditioning of the business floor W is stopped at night or on holidays, the exhaust heat is a large space and is diffused to the business floor W with a large amount of air, so there is no sudden temperature rise. .
In this way, the system can be easily introduced and the server can be stably operated without adding an air conditioner such as an air conditioner.

<5> Return flow path.
The return flow path 4 is a flow path for returning the air on the business floor W to the server room S as an alternative to the air collected by the heat collecting fan 2 and transported to the business floor W.
Since the business floor W and the server room S are adjacent to each other, the return flow path 4 is provided on a door or a wall surface between the business floor W and the server room S. The return channel 4 may be a louver or a fan unit.
By returning the air of the business floor W processed by the entire air conditioning, the server 1 can be stably operated at an appropriate temperature, and the server 1 has a long life.

<6> Silencer.
Since the server 1 generates noise, when noise in the server room S leaks to the work floor W, a noise reduction part is provided in the diffusion flow path 3 or the return flow path 4 to leak the noise. To prevent.
When the ceiling back space is used as the diffusion flow path 3, the space behind the ceiling itself becomes the exhaust silencer 32. Moreover, when using an extension duct as the diffusion flow path 3, a silencer box is provided as the exhaust silencer 32 (FIG. 4).
Further, a silencer box may be attached to the return flow path 4 as the intake silencer 41.

<7> The entire system.
Since the heat collection fan 2 added in the server room exhaust heat diffusion system of the present invention has low power consumption, the operation cost is kept low and the influence on the global environment is extremely small.
The form of the business floor W and the server room S, the scale of the server 1, and the like vary from site to site.
The server room exhaust heat diffusion system of the present invention can be constructed in accordance with the situation at each site by arranging the heat collecting fan 2 and selecting and combining each of the diffusion flow path 3 and the return flow path 4.
