Stacked Heat Exchanger
Need maximum thermal performance in minimal space? Stacked heat exchangers are engineered for high-efficiency heat transfer in a vertical or horizontal stacked configuration—ideal for industries where floor space is limited but cooling demand is high.
At United Cooling Systems, we design, manufacture, and supply durable, performance-driven stacked heat exchangers in Coimbatore, Tamil Nadu, India. Trusted by process plants, refineries, and power sectors, our solutions focus on compact design, easy maintenance, and operational efficiency to deliver top-tier thermal performance where it matters most.
What is a Stacked Heat Exchanger?
A stacked heat exchanger is a variation of the traditional heat exchanger design. In this setup, multiple tube bundles are arranged in a vertical stack, allowing for a more compact and efficient design. This configuration enhances heat transfer while minimizing the overall size, making it perfect for applications where space is limited but high heat transfer capacity is required.
The stacked heat exchanger maximizes the heat transfer surface area, improves efficiency, and provides flexibility for various industrial applications. It is often used when space constraints or heat transfer demands cannot be met by conventional heat exchangers.
How Stacked Heat Exchangers Work
- Tube Side: One fluid flows through the tubes, absorbing or releasing heat depending on whether it’s a heating or cooling process.
- Shell Side: The second fluid flows outside the tubes in the shell. Heat is transferred through the tube walls.
- Heat Transfer: Thermal energy passes from hot fluid to cold fluid via conduction through the tubes.
- Flow Configurations:
- Counterflow: Fluids move in opposite directions for maximum efficiency.
- Parallel Flow: Fluids move in the same direction, less efficient.
- Crossflow: One fluid flows perpendicular to the other for specialized cooling.
The stacked design increases surface area and allows higher fluid volume processing in the same space.
Stacked Heat Exchanger Components
- Shell: Houses the tube bundle and directs shell-side fluid flow.
- Tube Bundle: Removable tubes carrying fluid, designed for easy cleaning.
- Tube Sheets: Plates holding tubes in position, separating fluids.
- Channel Heads: Provide inlet and outlet for fluids.
- Baffles: Direct shell-side flow to enhance heat transfer.
- Nozzles: Entry and exit points for fluids.
- End Covers: Sealed covers containing shell-side fluid.
