Benefits of technology

The patent is about a heat exchanger made of a type of rubber film that has built-in systems to distribute fluid. The technical effect of this is that it makes it easier to transfer heat from one substance to another, which is useful in a variety of applications.

Problems solved by technology

However, polymers have relatively poor thermal conductivity, and it is not practical to construct a polymer heat exchanger based on conventional metal heat exchanger design principles.
Several designs have been proposed that adapt to the strength limitations of thin polymer interfaces, but none have resulted in a design simplicity that is required to dramatically lower costs.
As a result, polymer-based heat exchangers are today limited to relatively high value applications that require the inertness that polymers can provide, e.g., pharmaceutical processing, healthcare products, and corrosive fluid processing.
However, each of these examples also requires additional non-film components to complete the fluid circuits.

Embodiment Construction

[0018]A heat exchanger operates to transfer heat from one fluid to another. The fluid can be liquid, vapor, or gas or a combination of the matter states. Hygroscopic fluids can be extremely useful in certain heat exchanger applications to limit water use. Hygroscopic fluids can be extremely corrosive and polymers can provide excellent resistance to corrosive fluids.

[0019]There is a need for a polymer heat exchanger that is low cost in construction and less complicated than previous heat exchangers. Described herein is a heat exchanger that includes a stack of film layers (film stack). The film stack can include alternating fluid passages that are separate from each other. Each fluid passage can include an input port and an output port and the input ports and output ports can be arranged so that the heat exchanger operates on a counter flow basis; fluid A flows in one direction and fluid B flows in the opposite direction.

[0020]The entire fluid circuit for both heat-transfer fluids, i...

Description

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0001]This invention was made with government support under Energy Cooperative Agreement No. DE-AR0000309 awarded by the U.S. Department of Energy Advanced Research Project Agency. The government has certain rights in the invention.BACKGROUND[0002]Polymer-based heat exchangers offer unique benefits to end users including low-cost material of construction, resistance to fouling due to smooth surfaces, and generally excellent corrosion resistance. However, polymers have relatively poor thermal conductivity, and it is not practical to construct a polymer heat exchanger based on conventional metal heat exchanger design principles. In order for the polymers to have sufficient mechanical strength for conventional metal heat exchanger designs, the wall thicknesses would be so thick as to hinder effective heat transfer.[0003]Several designs have been proposed that adapt to the strength limitations of thin polymer interfaces, but...
