In addition, be known under the situation of the heat transfer paper that uses hoop (hoop) material, the size of heat transfer paper is because humidity etc. and changing on the direction vertical with hoop direction (coiling direction) easily.Thus, have following problem: owing to the contraction of making the heat transfer paper behind the heat exchange elements causes peeling off of adhesive segment, air-flow N and the mutual mixed flow of secondary gas flow M increase thus.In addition, have plate 102, thereby in heat exchange elements, produce the problem of bias current owing to the expansion of heat transfer paper is out of shape.Have heat exchanger effectiveness because this former thereby problem that reduces, requirement can not conducted heat paper distortion influence keep stable heat exchanger effectiveness.
As mentioned above, have following problem in existing heat exchange elements: because problems such as humidity and structure cause the distortion of heat transfer paper, the heat exchanger effectiveness performance becomes unstable thus.
