PROBLEM TO BE SOLVED: To provide a heat insulation structure capable of eliminating dew formation generated by partitioning different two temperature environments as a heat insulation panel, and a filter casing acting as a part of an air conditioner.SOLUTION: A heat insulation structure in which end edges of two metallic plates with principal planes being oppositely faced to each other are folded back to form, there is provided a heat insulation material held by the metallic plates and a clearance part between the opposing side plates, comprises a synthetic resin thread-engaging members passing between the principal planes of the metallic plates to keep a spaced-apart distance of the clearance part. In addition, a filter casing has rectangular openings inside the two pairs of inner metallic plates and filter units are installed at the openings. Sides opposing against the openings of the inner metallic plates are provided with outer metallic plates, the heat insulation material is held by the outer metallic plates and the inner metallic plates, a clearance is formed between the end edges of the outer metallic plates and the end edges of the inner metallic plates and there is provided a synthetic resin thread-engaging members to keep the spaced-apart distance of the clearance.SELECTED DRAWING: Figure 5 |
