Abstract
A heat-insulating housing (21) includes: a wall body; and an open-cell resin body (4) of thermosetting resin with which a heat-insulating space formed by the wall body is filled by integral foaming, the open-cell resin body including: a plurality of cells (47); a cell film portion (42); a cell skeleton portion (43); a first through-hole (44) formed so as to extend through the cell film portion; and a second through-hole (45) formed so as to extend through the cell skeleton portion, wherein the plurality of cells communicate with one another through the first through-hole and the second through-hole.
Claims17
A vacuum heat-insulating material comprising:
- an open-cell resin body filled in a heat-insulating space of the vacuum heat-insulating material and formed of a thermosetting resin;
- and
- powder dispersed in the open-cell resin body and incompatible with the open-cell resin body, wherein:
- the open-cell resin body includes a plurality of cells;
- at least some of the plurality of cells communicate with each other through a first through-hole formed by distortion at a molecular level generated when the open-cell resin body foams;
- and
- at least some of the plurality of cells communicate with each other through a second through-hole formed by the powder.
A heat-insulating box comprising a vacuum heat-insulating material,
- the vacuum heat-insulating material including:
- an open-cell resin body filled in a heat-insulating space of the vacuum heat-insulating material and formed of a thermosetting resin;
- and
- powder dispersed in the open-cell resin body and incompatible with the open-cell resin body, wherein:
- the open-cell resin body includes a plurality of cells;
- at least some of the plurality of cells communicate with each other through a first through-hole formed by distortion at a molecular level generated when the open-cell resin body foams;
- and
- at least some of the plurality of cells communicate with each other through a second through-hole formed by the powder.
