This utility model relates to the technical field of door and window profile components, and discloses a door and window profile component. It includes an outer frame, an inner frame installed at the upper end of the outer frame, glass fixedly connected to the inner wall of the inner frame, a connecting strip fixedly connected inside the outer frame, a heat insulation strip at the upper end of the connecting strip, and a thermal insulation structure between the outer and inner frame components. When this device is used for heat insulation, when cold air flows through the aluminum outer and inner frame components, the heat insulation strip blocks the cold air, conducting the temperature downwards. The thermal insulation structure slows down the temperature transfer, making it difficult for cold air to transfer from outside to inside the window. Furthermore, when the inner frame component moves the glass, the thermal insulation structure supports the inner frame component, preventing the heat insulation strip from bursting and damaging the outer frame component. The thermal insulation structure also better blocks the gap between the inner and outer frame components, resulting in better heat insulation performance.

This utility model relates to the field of heat preservation furnace technology, specifically a heat preservation furnace with heat insulation function. It includes a heat preservation furnace body, with a sealing cover plate installed on one side surface. The heat preservation furnace body has an inner shell and an outer shell. The inner shell has a first vacuum insulation layer, and the outer shell has a second vacuum insulation layer. A ceramic fiber layer is installed between the inner shell and the outer shell, and a heat insulation component is installed inside the ceramic fiber layer. In this improved heat preservation furnace, nitrogen stored in a gas tank is sequentially delivered to each gas bladder through a first and second gas pipe using a gas pump, filling the gas bladders with nitrogen. The low thermal conductivity of the gas helps improve the heat insulation effect of the heat preservation furnace body, reducing heat conduction. Furthermore, the first vacuum insulation layer of the inner shell and the second vacuum insulation layer of the outer shell provide heat insulation, preventing heat loss.
