HEAT INSULATING WALL, HEAT INSULATING BOX BODY AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2014149091
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve heat insulating performance when achieving communication in urethane foam by uniformizing the urethane foam and preventing appearance deformation.SOLUTION: A heat insulating wall according to the present invention comprises: a hollow wall body in which a hollow portion is a heat insulating space; a gas flow ports (6) for causing the heat insulating space (10) arranged in the wall body to communicate with the outside; open-cell urethane foam (4) foamed so as to fill the heat insulating space of the wall body; and a sealing material (60) for sealing the gas flow ports. A heat insulating box body according to the present invention comprises: an outer box (2); an inner box (3) housed in the outer box; the gas flow ports (6) for causing the heat insulating space (10) arranged between the outer box and the inner box to communicate with the outside; the open-cell urethane foam (4) foamed so as to fill the heat insulating space; and the sealing material (60) for sealing the gas flow ports.
