Claims

[Claims for Utility Model Registration] 1. A heat transfer fin 3 is inserted between two upper and lower tube plates 1, 1, and both end faces of the heat transfer fin 3 are closed with spacer bars 2 to form a fluid passage formed by stacking multiple layers. In the plate-fin type heat exchanger, upper and lower tube plates 1, which constitute a high-temperature fluid passage,
1. A plate fin type heat exchanger characterized in that a reinforcing plate 4 is attached to the front edge of the inner surface of the 1st inner surface, which is the fluid inlet side. 2 In a plate fin type heat exchanger constructed by stacking multiple stages of fluid passages formed by inserting a heat transfer fin 3 between two upper and lower tube plates 1, 1 and closing both end faces of the fin with a spacer bar 2. , upper and lower tube plates 1 forming a high-temperature fluid passage;
1. Reinforcement plates ₄ are provided on the front edge of the inner surface, which is the fluid inlet side, and on the left and right side edges that contact the spacer bar 2. , 4 ₂ , 4 ₃ and the plate surfaces of the reinforcing plates 4 ₂ , 4 ₃ that are in contact with the left and right side edges are wider than the spacer bar 2 and protrude toward the fluid passage side. type heat exchanger. 3. The orthogonal corner 4a between the reinforcing plate ₄₁ attached to the front edge of the tube plate 1 and the reinforcing plates ₄₂ and ₄₃ attached to the left and right side edges is formed obliquely. The plate fin type heat exchanger according to claim 2.
