(b) Plate fin exchangers

(c) Lamella plate heat exchangers

(d) Spiral plate heat exchangers

This question was addressed to me by my school principal while I was bunking the class.

My question is based upon Heat Transfer Applications in section Heat Transfer Applications of Food Processing Unit Operations

Answer 1

Right answer is (b) Plate fin exchangers

To explain I would say: Plate fin exchanger is also referred to as a matrix heat exchanger. In this heat exchanger, layers of corrugated sheets are made which is separated by flat metal plates therefore creating a series of finned chambers. The hot and cold fluid streams flow in alternate layers of the heat exchanger.
