Do two different types of heat exchangers with the same heat exchange area have equivalent cooling performance?

Do two different types of heat exchangers with the same heat exchange area, identical process fluid parameters, yield the same cooling effect? Can they be used interchangeably?

The heat exchange efficiency depends on the structure of the heat exchanger; plate heat exchangers have a high heat transfer coefficient.

The heat exchange efficiency will definitely vary depending on the structure

Originally it was a 16㎡ enamel plate-type condenser; by changing it to a spiral-plate type, what is the increase in heat exchange area?

The effects must be different, right? With the same heat exchange area, the heat exchange efficiency varies. Just like against the current and with the current, when the heat exchange area is the same, counter-current flow definitely yields better results

Different types of heat exchangers have different heat transfer coefficients, so they cannot be substituted for one another.

It cannot be replaced directly; advancedness needs to be calculated first. The heat exchange efficiency will not be the same

Agree with what was said above; it can’t be simply replaced.
