Pillow plate-heat exchanger with optimized flow configuration for increased efficiency
Summary:
A German university offers a new pillow-plate heat exchanger that offers several advantages over conventional systems. An optimized flow configuration, increased stream velocity and further new characteristics lead to higher heat transfer rates, more energy efficiency and less operating costs. Applications are manifold. Industrial licensees are sought.
Description:
Currently, pillow-plate heat exchangers (PPHE) enjoy growing attention and become increasingly employed in various branches of industry. The ongoing expansion of the PPHE exploitation area generates new structural requirements for this type of equipment. The flow configuration in PPHE is crucial for key aspects, such as, energy efficiency, operating costs and functionality. In conventional PPHE the flow can be redirected by baffles made of welding lines in the inner pillow-plate channels, but there is no method to improve the flow configuration in the outer channels.

For this reason, a research group of a German university developed a new PPHE, that enables the flow redirection also in the outer channels. This provides an optimized flow configuration in the entire heat exchanger. This can be customized according to the specific application. The new flow configuration is achieved by implementing various baffle elements within the pillow-plate stack, which offers the possibility of multiplied flow redirection either in the inner channels only, or in the outer channels only, or on both sides simultaneously, depending on the application.

The advantages of this construction are the optimized flow configuration (e.g. ideal counter-current flow), the increase of the mean stream velocity (e.g. important in applications with gases) in both channels leading to heat transfer enhancement, as well as a facilitated flow distribution among the outer channels at the inlet of the PPHE. The modified design is simple in assembling and can be easily implemented into existing manufacturing processes.

Such heat exchangers can be used in various industrial areas.
Possible applications include, e.g.:

· Gas cooler: improved gas-side heat transfer (outer channels) due to higher mean stream velocity resulting from the new baffle elements.
· Condenser with integrated super-cooling section: super-cooling of the condensate through the implementation of new baffles in the lower condenser section.
· Evaporator with integrated superheating section: superheating of the steam through the implementation of new baffles in the top evaporator section.

Industrial partners with activities in the above or other potential applications are sought for licensing agreements to optimize their processes.
