Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To miniaturize a heating tube, to reduce the manufacturing cost, and to reduce degradation and damages to the heating tube by fitting a stopper in a notch provided in a baffle for preventing the irregular flow of the gas to hold a support piece. SOLUTION: In a heat exchanger, a heating tube 1 is suspended by a support piece 2. A baffle 4 for preventing irregular flow of the gas is installed on a peripheral wall 3 to prevent the short pass of the gas between the heating tube 1 and the peripheral wall 3. A notch is provided in the baffle for preventing the irregular flow of the gas, the support piece 2 from which the heating tube 1 is suspended, is passed through the notch, and a stopper piece 6 is fitted to an inlet of the notch.  The stopper piece 6 restricts the oscillation of the support piece 2 in the horizontal direction, and the oscillation of the heating tube 1 consists of only small oscillation caused by a gap between a bent part of the heating tube 1 and the support piece 2, the baffle 4 for preventing the irregular flow of the gas also functions as the stopper for vibration control of the heating tube 1, and the structure can be simplified.
