MDE 13 Q1

1 / 6

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

C) The flow distribution plates

D) The pressure plates

B) The bolts and frame

A) The gaskets

2 / 6

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

D) To insulate the heat exchanger from external temperatures

A) To support the plates mechanically

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

C) To facilitate the flow of fluids between the plates

3 / 6

What is the purpose of the flow distribution plates in a plate-type heat exchanger?

D) To increase the overall weight of the heat exchanger

B) To provide structural support to the heat exchanger

A) To direct the fluid evenly across the entire plate surface

C) To separate the hot and cold fluids

4 / 6

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

A) On the sides of the heat exchanger

B) On the top and bottom of the heat exchanger

C) On the corners of the heat exchanger

D) On the front and back of the heat exchanger

5 / 6

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

A) Plates are arranged in a spiral pattern

D) Plates are arranged in a stacked circular configuration with a common central inlet

C) Plates are arranged in a parallel pattern with each plate having its own independent channel

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

6 / 6

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

B) Lower manufacturing cost, higher corrosion resistance, and less space requirement

D) Higher durability, simpler construction, and better temperature control

C) Lower pressure drop, higher fluid velocities, and reduced fouling

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