PURPOSE:To facilitate a fixing or a removal of a lid by a method wherein an engaging or disengaging element for removably holding the lid for use in opening or closing an insertion or removal port for inserting or removing some heat exchanging elements as well as a holder are extended at a pair of guide rails. CONSTITUTION:When a product is to be assembled, guide rails G1 and G2 for slidably guiding edges of heat exchanging elements 20 having polygonal section are fixed to the predetermined locations within a housing 11. Each of the guide rails G1, G2 is constructed such that an engaging or disengaging element 10 and a holder G20 are extended at base plates G11, G21 inserted into the housing 11. Accordingly, when a maintenance lid 12 is to be fixed, one end of the maintenance lid 12 is engaged with an engaging or disengaging claw 204 of the holder G20, then a turning part G103 of the engaging or disengaging element G0 is rotated in a counter-clockwise direction and the engaging or disengaging claw G104 is engaged with the other end of the lid 12 and then fixed. According to this arrangement, it is possible to perform an engaging or disengaging of the lid 12 under an easy operation only with a rotating operation of the rotating part G103. |
