HEAT  EXCHANGER  DESIGN  SERVICES

Designing different types of heat exchangers involves various considerations based on the specific application and operational requirements. Here’s a brief overview of each type you mentioned:

​

Plate Heat Exchanger (PHE) Design:

​

Consists of multiple thin, slightly separated plates that have very large surface areas and fluid flow passages for heat transfer.
Efficient for applications requiring high heat transfer coefficients and compact size.
Design considerations include plate material, gasket type, and configuration for specific heat transfer rates and pressure drops.

Shell and Tube Heat Exchanger Design:

​

Utilizes a series of tubes (often multiple small diameter tubes) within a larger shell to exchange heat between two fluids.
Commonly used in applications where one fluid needs to be heated or cooled significantly by the other.
Design factors include tube diameter, length, material, tube layout, baffle design, and choice of shell-side and tube-side flow arrangements (parallel, counterflow, crossflow).
Tube-in-Tube Heat Exchanger Design:

Involves concentric tubes where one fluid flows through the inner tube and the other flows through the annular space between the inner and outer tubes.
Suitable for applications requiring high pressure or where one fluid needs to be heated or cooled significantly.
Design parameters include tube diameter, length, material selection, and consideration of flow patterns for optimal heat transfer efficiency.

Tubular Heat Exchanger Design:

​

Refers to a broad category that includes shell and tube, tube-in-tube, and other variations using tubes as the primary heat transfer surface.
Design considerations depend on specific type (e.g., shell and tube, double pipe) and similar factors as mentioned above.

Air-to-Air Heat Exchanger Design:

​

Designed to transfer heat between two separate airstreams.
Commonly used for ventilation and HVAC systems to recover heat from exhaust air.
Design factors include air flow rates, temperature differences, heat transfer surface area, and materials to prevent cross-contamination between airstreams.

Plate and Frame Heat Exchanger Design:

​

Similar to PHE but typically involves larger, more complex configurations with frames supporting the plates.
Used in applications requiring higher flow rates and pressures compared to traditional PHEs.
Design considerations include plate and frame material, gasket type, and configuration for specific heat transfer rates and pressure drops.

Micro Channel Heat Exchanger Design:

​

Utilizes micro-scale channels to achieve high surface area-to-volume ratios and enhance heat transfer efficiency.
Often used in compact applications such as electronics cooling, automotive HVAC systems, and microreactors.
Design parameters include channel dimensions, materials (often metals or polymers), and manufacturing methods to achieve precise channel geometries.
Each type of heat exchanger design involves balancing factors such as heat transfer efficiency, pressure drop, material selection, manufacturing feasibility, and cost considerations to meet the specific needs of the application.
