MDE Unit 12 heat exchangers Flashcards

In a plate-type heat exchanger, how are the plates typically arranged?

A) Stacked horizontally with alternating flow channels

What is the primary function of the gaskets or seals in a plate-type heat exchanger?

B) To ensure the fluids do not mix and to prevent leakage

State THREE advantages of plate-type heat exchangers compared to tube-type heat exchangers.

A) Higher heat transfer efficiency, smaller footprint, and easier maintenance

Which component in a plate-type heat exchanger directs the flow of fluids and ensures proper distribution across the plates?

D) The distribution ports

In a plate-type heat exchanger, how are the plates arranged to facilitate heat transfer?

B) Plates are arranged in a single stack with alternating flow channels

With reference to plate-type heat exchangers, what is the purpose of tell-tales?

B) To provide an early warning of seal failure

In a plate-type heat exchanger, where are the fluid inlet and outlet connections typically located?

A) On the sides of the heat exchanger

What is the primary purpose of gaskets in a plate-type heat exchanger?

D) To maintain the structural integrity of the plates

In a typical plate-type heat exchanger, what is the common flow configuration?

C) Counter-current flow

With reference to plate-type heat exchangers, what is the purpose of the plates being corrugated?

B) To increase the surface area for heat transfer

Which of the following is a key component of a plate-type heat exchanger?

B) Gasketed plates

Which component in a plate-type heat exchanger helps to maintain the spacing between the plates?
