AI Technical Summary
Traditional medical vacuum insulation structures without helium magnets suffer from problems such as long vacuuming cycles, uneven vacuum levels, poor airtightness, and susceptibility to damage, failing to meet the requirements for high vacuum levels and low heat leakage.
The structure adopts a combination of inner and outer reflective screens and sandwich insulation components. The inner reflective screen is made of polyester polymer and double-sided vacuum-plated aluminum material, while the outer reflective screen is made of glass fiber and aluminum foil. The sandwich insulation components adopt a gradient material stacking design and replace traditional stitching with laser cutting and hot-melt sealing to form an air extraction channel and a pinhole-free seal.
It improves vacuuming efficiency and airtightness, ensures uniform vacuum level and structural integrity of the interlayer, reduces thermal bridging, protects the insulation layer from welding damage, meets the requirements of high vacuum and low thermal conductivity, and extends service life.
