Embodiment Construction

[0016] figure 1 It is a structural schematic diagram of the present invention; figure 2 It is a schematic diagram of the structure of the absorber, as shown in the figure: the vacuum insulation panel with built-in absorber in this embodiment includes a glass fiber core material 1, an aluminum foil 2 sealed and wrapped outside the glass fiber core material 1, and an aluminum foil 2 arranged inside Absorber 3 for absorbing water, the inside of aluminum foil 2 is evacuated, said absorber 3 includes absorbent container 4 and absorbent 5 arranged in absorbent container 4, said absorbent 5 includes quicklime and zeolite, made of quicklime and According to the chemical properties of zeolite, quicklime and water can produce CaO+H 2 O→Ca(OH) 2 The chemical reaction has strong water absorption. At the same time, zeolite also has strong water absorption and can be used as a desiccant. The quicklime and zeolite are both granular, and the particle size is 1-5mm. If the particle size is ...

Abstract

The invention discloses a vacuum insulating board with a built-in absorber, which comprises glass fiber core materials, an aluminum foil and the absorber. The aluminum foil is hermetically coated outside the glass fiber core materials; the inside of the aluminum foil is vacuumized; the absorber is arranged in the aluminum foil and used for water absorption; and the absorber comprises an absorbent container and an absorbent arranged in the absorbent container. Because the absorbent can effectively absorb the residual water of the glass fiber core materials and the penetrated water in the aluminum foil, the invention can effectively improve the vacuum degree in the aluminum foil, thereby reducing the heat conductivity factor of the insulating board and improving the heat insulation effect of the insulating board.

Description

technical field [0001] The invention relates to heat insulation materials, in particular to a vacuum heat insulation panel with a built-in absorber. Background technique [0002] In refrigeration equipment such as refrigerators and freezers, the outer wall of the equipment needs to be made into interlayers, and filling materials with low thermal conductivity are arranged in the interlayers to reduce heat loss and energy consumption. [0003] At present, the commonly used filling material is polyurethane foam. However, due to the heat transfer of air, polyurethane foam is very limited in improving the thermal insulation effect. In order to improve the cooling effect and save energy, an improved thermal insulation structure is put into use. The vacuum insulation panel is placed in the interlayer and laminated with polyurethane foam to form a heat insulation layer. The vacuum insulation panel used in this structure can achieve a good heat insulation effect, but because there is...
