Does an increase in the wall thickness of a heat exchange vessel have a significant impact on its heat exchange efficiency?

Assuming that the original wall thickness of the tank was 3 mm (made of 304 stainless steel), it took half an hour to achieve the desired heat exchange effect. Now that the wall thickness of the tank has become 15 mm, will there be a significant difference in the time required to achieve the same heat exchange efficiency, with all other parameters remaining unchanged?
Does an increased wall thickness of the heat exchange vessel have an impact on the heat exchange efficiency?
There is an impact, but it is not linear. Check the formula for K – the effect of the ratio of the wall thickness δ to the thermal conductivity λ (δ/λ) on K.
Q = q1r = q2c(t2 – t1); the radius is proportional to the temperature difference. If it is thickened by a factor of 5, and if q1 = 1, q2 = 1, C = 1, and t1 = 1, then the original temperature is 4, while the temperature after the radius changes is 16 – an increase of 4 times. Other results can be assumed by oneself~
A jacketed container? It is possible to examine the thermal resistance of each component. Generally, when there is forced convection heat transfer on both the inner and outer sides of the vessel wall, the thermal conduction resistance of the vessel wall accounts for a large proportion of the total thermal resistance; in such cases, increasing the wall thickness will certainly have a significant impact on heat transfer
