PURPOSE:To provide a plate type heat exchanger in which a stopper is not welded to a fixed frame and a co-turning of a fastening bolt during a fastening of a fastening nut can be positively prevented. CONSTITUTION:A moving frame 5 is movably and axially suspended at guide bars 3, 4 bridged between an opposed fixed frame 1 and a supporting leg 2. Both end edges in a width direction of the fixed frame and the moving frame are oppositely formed with recesses 16 at a constant pitch in which a plurality of laminated heat transfer plates 8 are cooperatively fastened with fastening nuts 11 through a gasket 9 and some fastening bolts 10 can be fitted under its horizontal attitude. An outer circumferential edge of the recess of one frame of both frames is forked with a recess part 32 to which a head part 18 of each of the fastening bolts can be fitted and engaged. |
