Dimple plate heat exchanger advantages
Energy efficiency and performance
Dimple plates deliver outstanding energy efficiency in industrial heat transfer applications. SHPHE’s Pillow Plate design maximizes thermal energy transfer by creating turbulent flow within the internal cavities. This turbulence increases the heat transfer coefficient, which leads to superior performance compared to traditional smooth tubes. Studies show that dimple plate heat exchangers can achieve more than 200% improvement in heat transfer capacity over smooth tubes. The following table highlights key performance metrics from recent research:
Study | Findings | Heat Transfer Capacity Increase | Comprehensive Heat Transfer Coefficient |
|---|---|---|---|
Li et al. | Dimpled tube vs. smooth tube | More than 200% | Over 1.5 |
Afanasyev et al. | Spherical cavities enhance heat transfer | 30–40% | N/A |
Muley et al. | Corrugation angle boosts heat transfer | 2–5 times higher than flat plates | N/A |
Dimple plates also reduce operational costs by lowering energy consumption. Enhanced cooling efficiency supports sustainable production and helps industries meet environmental targets.
Design flexibility
SHPHE’s Pillow Plate offers unmatched design flexibility. Dimple plates adapt easily to different shapes and sizes, making them suitable for tanks, vessels, and custom process equipment. Unlike shell-and-tube heat exchangers, which have rigid structural constraints, dimple plates allow for straightforward customization. Plate geometry and arrangement can be tailored to specific requirements, enabling users to increase capacity or optimize performance after installation. This flexibility supports a wide range of industrial processes and ensures that dimple plate heat exchanger solutions fit unique operational needs.
Tip: Dimple plates can be manufactured from various materials, including stainless steel and titanium, to match the demands of food, chemical, or environmental applications.
Low pressure drop
Dimple plates excel at minimizing pressure drop, which is crucial for efficient system operation. The optimized geometry of SHPHE’s Pillow Plate ensures smooth fluid flow and reduces resistance. Research demonstrates that dimpled fins with diameters ranging from 2 mm to 6 mm can lower pressure drop by up to 58% compared to smooth fins at certain velocities. The following list summarizes typical pressure drop values:
Dimpled fins (2 mm): 53% reduction at 16 m/s compared to smooth fins.
Dimpled fins (6 mm): 55% reduction at 12 m/s compared to smooth fins and 2 mm dimples.
Dimpled fins (4 mm): 58% reduction at lower velocities compared to smooth fins.
Low pressure drop enhances energy efficiency and reduces pump requirements, which leads to lower operational costs and improved overall system performance.

Dimple plates deliver reliable performance and help industries achieve their financial and sustainability goals.
Dimple plate heat exchanger disadvantages
Limited heat transfer compared to some types
Engineers often compare the heat transfer efficiency of dimple plate heat exchangers to other designs. Studies show that dimpled tubes increase the overall heat transfer coefficient by 14.2% compared to smooth tubes in shell-and-tube heat exchangers. The temperature change at the tube side rises by 15% with dimpled tubes. However, some plate heat exchangers and advanced shell-and-tube models can deliver even higher performance under specific conditions. Users must evaluate their process requirements to determine if the dimple plate heat exchanger meets their thermal needs.
Dimpled tubes enhance heat transfer coefficient by 14.2% over smooth tubes.

Tube-side temperature change rises by 15% with dimpled tubes.
SHPHE recommends a thorough analysis of process demands before selecting a heat exchanger type.
Size and installation challenges
Industrial users sometimes face challenges with the size and installation of dimple plate heat exchangers. Large units may require significant space, which can complicate integration into existing facilities. In high-pressure or high-temperature applications, precise alignment is essential to maintain operational integrity. Specialized tools and skilled labor often become necessary, increasing project costs. Installation expenses can escalate based on site conditions and system complexity, sometimes adding thousands of dollars to the budget. If extensive modifications are needed, the timeline for commissioning may extend. Ongoing costs such as cleaning and gasket replacements also contribute to the total cost of ownership.
Note: The ease of integrating a dimple plate heat exchanger into an existing system depends on site layout and process requirements.
Maintenance and clogging risks
Maintenance remains a key concern for operators using dimple plate heat exchangers. Fouling layers can act as insulating barriers, reducing heat transfer efficiency and overall performance. Increased maintenance and operating costs often result from fouling. Severe cases may lead to higher capital investment and production losses. Frequent cleaning becomes necessary, which can be costly and time-consuming. Flow obstructions and increased pressure drops may occur due to various types of fouling.
