The present application relates to a spiral heat exchanger and a heat exchange device. The spiral heat exchanger comprises: a core shaft with an axis extending in the left-right direction; a first liquid-passing coiled tape with a spiral liquid flow channel therein wound around the axis of the core shaft at least two circles to form a spiral shape; and seal strips sealed between the sides of two heat conduction thin tapes and the spiral liquid flow channel formed between the seal strips and between the two heat conduction thin tapes, wherein adjacent circles of the first liquid-passing coiled tape is isolated by a certain distance maintained by a duct support to prevent the adjacent circles from sticking to each other to create a blockage in the spiral airflow channel.

The present invention relates to a management method and a device for hazardous chemicals and a construction method of a management database. The construction method comprises following steps: determining a plurality of entities involved in entire lifecycle of hazardous chemicals; classifying the plurality of entities to define a plurality of entity classes involved in the management database; defining a plurality of relationship classes according to one or more relationships involved between every two of the entity classes; using the relationship from one or more of the relationship classes to constrain the relationships between every two entities, so as to construct an ontology of the database; and importing actual data of the hazardous chemicals throughout their entire lifecycle into the ontology, so as to carry out instantiation of the ontology. By implementing this construction method, a management database for hazardous chemicals can be obtained, which can break the island phenomenon of multi-field data by integrating and fusing the multi-filed data throughout the entire lifecycle of hazardous chemicals, thereby achieving the effects of reasonable resource allocation, dynamic warning and supervision, and emergency linkage.

Management method and device for hazardous chemicals, and a construction method for a management database

Approaches provided herein include a protection device assembly having a protection component and a first electrode layer extending along a first main side of the protection component. The first electrode layer may include a first section separated from a second section by a first gap. The assembly may further include a second electrode layer extending along a second main side of the protection component, the second electrode layer including a third section separated from a fourth section by a second gap, wherein the first gap is aligned with the second gap. The assembly may further include a first insulation layer disposed over the first electrode layer, and a second insulation layer disposed over the second electrode layer. The assembly may further include a solder pad extending around an end of the protection component, the solder pad further extending over the first insulation layer and the second insulation layer.
