Description

[0001]
[Industrial application fields]
The present invention relates to a seepage cooling chamber structure.
[0002]
[Prior art]
For example, in the event of a fire, in order to protect a room in a building from the heat of the fire, it has been proposed to ooze the room into a cooling room.
[0003]
That is, as shown in FIGS. 10 and 11, a water supply tube 3 made of stainless steel or the like is spread around the outer surface of a structural wall 2 in a cooling chamber 1 provided inside a building (not shown), and the water supply A large number of water supply holes 4 are formed at appropriate intervals in the tube 3, and a hard heat-resistant porous material 5 such as ceramic paper is attached to the outside of the water supply tube 3 to a required thickness. Water 7 stored in advance in a water supply source 6 such as a tank provided can be supplied to the water supply tube 3 through a water supply pump 8 and a water supply pipe 9.
[0004]
The heat-resistant porous material 5 may be embedded in the water supply tube 3 as shown in FIG. 10, or may be installed outside the water supply tube 3 as shown in FIG. good.
[0005]
During normal times, the water 7 stored in the water supply source 6 such as a tank is not sent to the water supply tube 3 and is stored in the water supply source 6 by driving the water supply pump 8 in the event of a fire. The water 7 is fed to the water supply tube 3 through the water supply pipe 9 and spreads from the water supply hole 4 formed in the water supply tube 3 to the entire surface of the heat-resistant porous material 5 by the water supply pressure and capillary action by the water supply pump 8. I will let you.
[0006]
Then, when the water 7 flows through the water supply tube 3 provided so as to surround the cooling chamber 1 and directly cools the cooling chamber 1 by heat transfer and spreads in the heat-resistant porous material 5, Since the latent heat of vaporization is taken away from the heat-resistant porous material 5 and cooled (exudation cooling), the inside of the cooling chamber 1 is kept at a low temperature by the double cooling effect.
[0007]
When the water 7 is evaporated from the heat resistant porous material 5, the water 7 in the water supply tube 3 is replenished to the heat resistant porous material 5 by the water supply pressure and capillary action by the water supply pump 8, and the above operation is performed. Continued.
[0008]
As described above, the cooling chamber 1 can be effectively cooled with a small amount of water 7.
[0009]
[Problems to be solved by the invention]
However, the conventional seepage cooling chamber structure has the following problems.
[0010]
That is, since the cooling chamber 1 is cooled using evaporation of the water 7 or the like, the temperature in the cooling chamber 1 is kept below 100 degrees which is the evaporation temperature of the water 7 even in the case of a fire or the like. In fact, even when the temperature outside the cooling chamber 1 exceeds 1000 degrees, the temperature inside the cooling chamber 1 is suppressed to 100 degrees to 60 degrees.
[0011]
However, the temperature in the cooling chamber 1 being in the range of 100 degrees to 60 degrees is sufficient to prevent furniture, furniture, and other items in the cooling chamber 1 from being burned out. It is still insufficient to protect heat-sensitive devices 10 such as humans in the room and computers in the cooling room 1.
[0012]
The temperature in the cooling chamber 1 is in the range of 100 degrees to 60 degrees because the flow rate of the water 7 flowing through the water supply tube 3 is slow and the flow rate is small, and the water flowing through the water supply tube 3 due to the heat of the fire. This is because 7 is immediately heated to 100 to 60 degrees.
[0013]
In view of the above circumstances, an object of the present invention is to provide a seepage cooling chamber structure that can keep a room at a locally lower temperature.
[0014]
[Means for Solving the Problems]
In order to solve the above problems, the present invention uses the following means.

[0017]
Alternatively, the outer cooling chamber may be configured to cover the outer surface of the robot body, and the inner cooling chamber may accommodate the internal equipment of the robot body.
[0018]
