Abstract

PURPOSE:To properly feed chilled gas in a containing chamber, to uniformly cool electronic devices, and to further improve a volume efficiency and economy by providing a shielding plate between one side of a row of the devices and the sidewall of the chamber. CONSTITUTION:Two rows of electronic device trestles are deviated laterally to be disposed, and one ends of the rows are connected to the sidewalls of a containing chamber via shielding plates 61, 62. As a result, chilled gas of an air conditioner 51 is not introduced to the back of the row 22 of the trestle, and hence brought into direct contact with the front as indicated by arrows to be sucked from a suction port of the front of each device, and discharged through the device from an exhaust port of the back. Thus, the cooling efficiency of the device is enhanced, the devices can be substantially uniformly cooled at the same time. Accordingly, space utility ratio of the containing chamber is enhanced, and economy of an air conditioner system can be simultaneously enhanced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air-conditioning system for a housing chamber that houses devices that require heat radiation such as electronic devices, and particularly relates to an air-conditioning system for a portable exchanger that houses an exchanger in a container. Regarding.

[Prior art] A conventional air conditioning system for an electronic equipment storage room is disclosed in Japanese Patent Application Laid-Open No. 1-1576.
As described in Publication No. 90, an air conditioner is installed in one corner of the container, and the cold air from the air conditioner is guided into a duct installed on the ceiling inside the container, and from its outlet to the intake port installed at the top of the portable exchanger. Cool air was blown out towards the building, and was also exhausted through the space under the floor from the air outlet at the bottom of the portable exchanger.

Furthermore, as described in Japanese Patent Application Laid-Open No. 59-114900, the door of each electronic device frame is curved and protruded to make it easier to take in the cold air flowing along the sides of the electronic device frame. , an intake opening was provided on the side in which the cold air arrived.

In addition, as described in Japanese Patent Application Laid-open No. 1-89780, in order to make it easier to take in the cold air flowing along the sides of the electronic device frame, an air intake plate can be extended from the door of each electronic device frame. It's Ll.

FIG. 2 is a diagram showing an example of another conventional air conditioning system for an electronic device storage chamber.

Inside the storage chamber 1, rows 21 and 22 of racks accommodating a plurality of electronic device racks 2 are arranged in two rows facing each other. Each electronic device rack 2 takes in cold air output from air conditioners 51, 52, 53, etc. through an intake port 3 provided on its front surface, and exhausts it through an exhaust port 4 provided on its back surface. was.

[Problem to be solved by the invention] In the method described in the above-mentioned Japanese Patent Application Laid-Open No. 1-157690,
Since the duct installed inside the container occupies a large amount of the narrow container volume, there is a problem that the M9m space of the exchanger becomes narrow and the price increases at the same time.

In addition, the methods described in JP-A-59-114900 and JP-A-1-89780 lack consideration for optimizing the flow of cold air and temperature distribution throughout the storage chamber, so they are particularly useful for large numbers of electronic device racks and When installing an air conditioner, there is a problem in that the flow of cold air becomes complicated and localized overheating occurs.

Moreover, in the conventional arrangement shown in FIG.

Since the cold air also circulates around the backs of the rows 21 and 22 of each rack, the cold air does not necessarily flow in such a way as to be sucked in through the intake ports 3 on the front side and exhausted through the exhaust ports 4 on the back side. Since convection stagnates or even flows backwards inside the equipment rack 2, the temperature distribution may become extremely uneven as shown in FIG. 3.

In FIG. 3, since the flow of cold air in the electronic device on the right is poor, the temperature locally increases significantly compared to the electronic device on the left. Furthermore, in order to prevent such a temperature rise, for example, a louver has been provided on the front surface of an electronic device.

An object of the present invention is to improve the above-mentioned conventional problems by optimizing the flow of cold air in a storage chamber, thereby uniformly cooling each electronic device, and further improving the volumetric efficiency and economic efficiency of an electronic device. The purpose is to provide an air conditioning method for the containment room.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides an electronic device having an intake port on one side and an exhaust port on the opposite side, in which the intake port surface and the exhaust port surface are the same. The electronic devices are arranged in rows so as to form a plane, and the rows of the electronic devices are arranged in two rows with their respective intake ports facing each other and housed in the storage chamber, and one side of each row of the electronic devices and The space between the side walls of the accommodation chamber is shielded by a shielding plate, and each of the at least two air conditioners is arranged to face the intake port side of each of the two rows of electronic devices and the shielding plate side. .

Further, the rows of electronic devices are arranged so as to be shifted from each other in the direction of the respective rows, so that the surface area of the inlet port of the row of electronic devices facing the cold air discharge port of each air conditioner is expanded.

Further, the row of electronic devices is divided into a plurality of parts with intervals,
A shielding plate is provided between one side of each of the divided rows of electronic devices and the side wall of the storage chamber, and each of the plurality of air conditioners is placed opposite to the intake port side of each of the divided rows of electronic devices. The shielding plate is arranged so as to be located on the shielding plate side.

Further, the divided rows of electronic devices are arranged so as to be shifted from each other in the direction of the respective rows, so that the lateral area of the intake port of the row of electronic devices facing the cold air outlet of each air conditioner is expanded. Make it.

Further, the array of electronic devices is housed in a rack, and the shielding plate is held on the rack so as to be freely removable.

[Function] The air conditioning method for the electronic device storage chamber of the present invention configured as described above guides the cold air discharged by the air conditioner to the intake port side of each electronic device, and at the same time, the cold air is directed to the air intake side of each electronic device. This improves the circulation of cold air inside each electronic device by preventing it from going around to the exhaust port side.

[Embodiment] FIG. 1 is a perspective view of an embodiment of an air conditioning system for an electronic device storage chamber according to the present invention, and FIG. 4 is a top view thereof.

As shown in FIG. 4, the two rows of electronic device racks are laterally offset, and one end of each row is connected to the side wall of the storage chamber by a respective shielding plate 61 and 62.

As a result, the cold air from the air conditioner 51 cannot go around behind the row of racks 22, so it hits the front of the rack directly, as shown by the arrow, and is sucked in through the intake ports on the front of each electronic device.
The air passes through each electronic device and is exhausted from the exhaust port on the back of the same device.

FIG. 5 shows the measurement results of temperature distribution in the air conditioning system of the present invention shown in FIGS. 1 and 4 above.

In Fig. 5, the local temperature rise seen in the temperature distribution of the conventional method shown in Fig. 3 has been eliminated, and at the same time, the maximum temperature has been reduced from 70°C to 50°C, so each electronic device It can be seen that the rack is cooled almost evenly.

and 22 respectively 211.212 and 221.222
At the same time, the rack rows 211 and 212 are arranged in two halves as shown in the figure.
An air conditioner 53 is added between the rows of racks 221 and 222, an air conditioner 54 is added between the rows of racks 221 and 222, and the gap between the side wall of the storage chamber where the air conditioner 53 is installed and the row of racks 211 is covered with a shielding plate 63. Similarly, a gap between the side wall of the accommodation chamber to which the air conditioner 54 is attached and the rack row 222 is blocked by a shielding plate 64.

Although Fig. 6 shows the case where each row of racks is divided into two, for example, if the storage room 1 has a large space and the row of racks is long, each row of racks can be divided into two. Divide it into smaller pieces and attach shielding plates in the same way.

In FIG. 6, by providing each of the above-mentioned shielding plates, the cold air coming out of each air conditioner flows as shown by each arrow, so, for example, the cold air coming out of the air conditioner 51 mainly hits the rack row 221, The air is sucked in through the intake hole on the front side of each electronic device and exhausted through the exhaust hole on the back side of each electronic device, thereby cooling each electronic device in the rack row 221 almost equally.

Similarly, the cold air from the air conditioner 52 mainly cools each electronic device in the rack row 212 almost evenly, and the cool air from the air conditioner 53 mainly cools each electronic device in the rack row 222 almost evenly. The cold air discharged from the air conditioner 54 mainly cools each electronic device in the rack row 211 almost equally.

As a result, the temperature distribution within the storage chamber 1 becomes as shown in FIG. 7, and each electronic device rack is cooled almost equally.

In the embodiment of the present invention shown in FIG. 1 and FIGS. 4 to 7, the rows of racks are arranged so as to be staggered from each other in the row direction. In some cases, the width of each shielding plate can be made sufficiently wide, thereby guiding the cold air toward each intake port, so it is recommended to arrange the two rows of racks directly facing each other. You can.

In addition, each shielding plate is housed inside the rack closest to it so that it can be taken in and out, and when necessary, it can be pulled out and fixed to the wall of the storage room, and its mounting angle can be adjusted freely. It can also be done.

[Effects of the Invention] According to the present invention, the cold air discharged by the air conditioner is evenly guided to the respective intake ports of each electronic device, and at the same time, the cold air is prevented from going around to the exhaust port side of each electronic device. Therefore, the cooling efficiency of each electronic device can be increased, and at the same time, each electronic device can be cooled almost uniformly.

In addition, since the cold air from the air conditioner can be effectively guided with a simple shielding plate, the duct for guiding cold air in the conventional method can be omitted, thereby increasing the space utilization rate of the storage room and at the same time The economic efficiency of the method can be improved.
