Abstract
The present invention relates to a vacuum insulating panel (VIP). The VIP comprises an insulating core (2) having upper (3) and lower surfaces (4) and at least one substantially planar reinforcing member (5) arranged on the upper (3) or lower surface (4) of the core (2). The reinforcing member (5) is porous and substantially rigid. The VIP further comprises a barrier envelope, optionally in the form of a barrier film (6), arranged to envelop the insulating core (2) and the planar member (5). The present invention also relates to methods of manufacturing a vacuum insulating panel (VIP).
Claims22
A vacuum insulating panel comprising:
- a porous insulating core having an upper surface and a lower surface and sides, the insulating core is constructed from a microporous insulating material formed from a powder material;
- at least one reinforcing member arranged on the upper or lower surface of the insulating core to reinforce the core, the reinforcing member is formed of a porous material, and is substantially rigid;
- the at least one reinforcing member and the insulating core form a hybrid core and the at least one reinforcing member does not form a thermal bridge across the insulating core;
- an envelope, arranged to envelop the hybrid core, the envelope maintains an applied vacuum within the envelope;
- density of the insulating core within the vacuum insulating panel is from 100 kg/m3 to 160 kg/m3;
- and
- thermal conductivity of the vacuum insulating panel is in the range of from 3.0 mW/m·K to 4.0 mW/m·K.
A method for manufacturing a vacuum insulating panel, comprising:
- providing a porous insulating core having an upper surface and a lower surface and sides, the insulating core is constructed from a microporous insulating material formed from a powder material;
- arranging at least one reinforcing member on the upper or lower surface of the insulating core to reinforce the core, the reinforcing member is formed of a porous material, and is substantially rigid;
- the at least one reinforcing member and the insulating core form a hybrid core and the at least one reinforcing member does not form a thermal bridge across the insulating core;
- enveloping the hybrid core with a barrier envelope;
- applying a vacuum to evacuate the barrier envelope, so that the barrier envelope closely engages the insulating core and the at least one reinforcing member of the hybrid core;
- the density of the insulating core within the vacuum insulating panel is of from 100 kg/m3 to 160 kg/m3, and
- thermal conductivity of the vacuum insulating panel is in the range of from 3.0 mW/m·K to 4.0 mW/m·K.
