Through the arrangement of the heat insulation and preservation assembly, the heat insulation and preservation performance of the door and window is effectively improved, indoor and outdoor heat transfer can be blocked when the weather is hot or cold, the indoor temperature is kept comfortable and stable, and meanwhile operation is easy and convenient, and use is convenient and fast.

The utility model belongs to the technical field of energy -conserving commercial refrigerator, concretely relates to a kind of aerogel composite refrigerator glass cover plate. The aerogel layer is located between the outer glass layer and the inner glass layer, the aerogel layer has gradient pore structure, and the pore size of the aerogel layer changes from large to small from the direction close to the outer glass layer to the direction away from the outer glass layer. The application fills the air layer part of traditional double-layer hollow glass with high-transmittance aerogel material, has high-transmittance and excellent heat preservation performance, and the cover plate can be thinned, which is very suitable for equipment with internal material display requirements, such as commercial ice cream cabinet.

The utility model relates to surface water detection technical field, and disclose a kind of storage device with heat preservation function for surface water detection, including device main body, the upper side of device main body is fixedly arranged with docking pipe, the outer side of docking pipe is movably provided with sealing cover, the upper side of sealing cover is fixedly arranged with display screen, the inner side below sealing cover is fixedly arranged with connecting piece, data processing module is fixedly arranged on the connecting piece, the lower side of data processing module is fixedly arranged with multiple temperature sensors.The storage device with heat preservation function for surface water detection, through the electrical connection of data processing module and heater, the intelligent control of water temperature is realized, when water temperature is lower than set threshold value, data processing module automatically controls heater to start heating, so that water temperature is kept in suitable range, without frequent manual intervention, improve work efficiency, also ensure that water sample temperature is always in stable state.

This invention provides an infrared defrosting device, comprising a housing, an inner liner, an infrared heater, a fan, and a flow guide. The inner liner contains a heating zone for placing the item to be heated and a heat source zone equipped with the infrared heater. The infrared heater's irradiation direction faces the heating zone. The fan generates airflow from the heat source zone to the heating zone. The flow guide alters the direction of the airflow generated by the fan as it passes the infrared heater, making it non-parallel to the irradiation direction of the heater. This design, through fan-driven airflow circulation, delivers high-temperature air from the heat source zone to the heating zone, accelerating heat exchange on the surface of the item. Simultaneously, it prevents the fan from obstructing the infrared heater and allows infrared radiation and airflow to heat different surfaces of the item separately, resulting in staggered coverage areas and preventing localized overheating or underheating of the item.

The utility model relates to the field of processing technology of an aluminum-plastic co-extrusion inside-outside flush screen window integrated window, and discloses an aluminum-plastic co-extrusion inside-outside double-pressing-line installation part which comprises an outward-opening conversion frame, installation frames are fixedly connected to the top side and the bottom side of the outward-opening conversion frame respectively, a nylon 66 heat insulation bridge is installed at the middle end of the installation frame at the top end, and the nylon 66 heat insulation bridge is installed at the bottom end of the outward-opening conversion frame. Inner buckling and pressing lines are installed at the left ends of the sides, away from each other, of the mounting frames at the two ends, outer buckling and pressing lines are installed at the right ends of the sides, away from each other, of the mounting frames at the two ends, and upper light fixing glass is arranged between the inner buckling and pressing lines and the outer buckling and pressing lines. In the utility model, the traditional single indoor ultra-large pressing line fixation is abandoned, and the inner buckling line and the outer buckling line are adopted to cooperatively fix the glass from the indoor side and the outdoor side. The inner buckling and pressing line is of a conventional specification, installation difficulty and cost are reduced, stress is dispersed through cooperation of the inner buckling and pressing line and the inner buckling and pressing line, glass can be stably lighted and fixed and effectively prevented from deviating in a large window frame, installation operation is convenient, and stability of the glass after installation is enhanced.
