The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
A kind of insulated cabinet door, comprise doorframe 1, outer glassy layer 2 and interior glassy layer 3, between described outer glassy layer 2 and interior glassy layer 3, be filled with mist 4, described mist is inert gas and thermo-responsive gas, and the pressure of described outer glassy layer 2 and interior glassy layer 3 is greater than 0.8 and is less than 1.15 atmospheric pressure.
Temperature between layer glass layer changes along with the variation of temperature.
By being arranged on the mist 4 in cabinet door, decline along with temperature in doorframe, its coefficient of heat conduction reduces, heat transfer speed is slack-off, make the good heat-insulation effect of whole cabinet door, the temperature of glass outer layer approaches ambient temperature, and inner layer glass layer approaches the temperature in cabinet chamber, therefore, cabinet door exterior surface can dewfall, and can effectively guarantee that refrigerator normally works.
Especially thermo-responsive gas, thus thermo-responsive gas can make the vacuum that causes in two glassy layers make the molecular motion in gas slack-off, by mixing of thermo-responsive gas and inert gas 4, further reduces the heat conduction of doorframe 1.
Thermo-responsive gas is when normal temperature or when low temperature, and inner meeting produces high pressure, can be controlled at 1.2 atmospheric pressure once, so must choose thermo-responsive gaseous species and the strict ratio of inert gas.
