Beschreibung
Zusammenfassung:	The utility model provides a heat exchange structure and a gas appliance. The heat exchange structure comprises a plurality of combustion chamber inner walls which define a combustion chamber inner cavity; the combustion chamber outer wall surrounds the outer side of the combustion chamber inner wall, a ventilation interlayer is formed between the combustion chamber outer wall and the combustion chamber inner wall, and the ventilation interlayer is provided with an interlayer channel; the relationship between the thickness delta of the ventilation interlayer and the surface temperature T of the outer wall of the combustion chamber meets a dimensionless formula: T = K1-K2 delta 2 + K3 delta + delta (K4 lambda1 + K5 lambda2) * 10 + K6 lambda1-K7 lambda12-K8 lambda2 + K9 lambda22 + K10 lambda1 * lambda2; wherein K1 is equal to 441 to 539, and K2 is equal to 2.907 to 3.553; k < 3 > is equal to 65.529 to 80.091; k < 4 > is equal to 1.89 to 2.31; k < 5 > is equal to 3.42 to 4.18; k < 6 > is equal to 0.342 to
