EFFUSION COOLING CHAMBER STRUCTURE

Japanese Patent JP3656284

B2

PURPOSE: To locally keep the inside of a chamber at low temperature by providing an inside cooling chamber composed of a water supply tube having a water supply hole and a heat resistantant porous material in the inside of the outside cooling chamber composed of a water supply tube having a water supply hole and a heat resistant porous material.
CONSTITUTION: Water 20 in a water supply source 19 is sent to an outside cooling chamber 17 and a water supply tube 12 for an effusion cooling panel 15 constituting an inside cooling chamber 18 respectively by driving a water supply pump 21 in case of fire, and it is made to effuse and spread from a water supply hole of the water supply tube 12 to a heat resistant porous material 14 of the effusion cooling panel 15 by water feeding pressure and a capillary phenomenon. Then, the water 20 flowing in the water supply tube 12 directly cools the effusion cooling panel 15 by heat transfer and, when it is effused and spread in the heat resistantant porous material 14 and evaporated by the heat of the fire, it cools the heat resistant porous material 14 by absorbing the evaporation latent heat therefrom so that the inside and outside cooling chambers 18, 17 are kept are low temperature by double cooling effects.
