Description

This application claims the benefit of and priority to U.S. Provisional Patent Application Serial No. 63/671,970 filed July 16, 2024 .

TECHNICAL FIELD

The present disclosure relates to tube sheets used in the technical field of heat transfer and fluid dynamics, specifically within the design and manufacturing of heat exchangers and pressure vessels.

BACKGROUND

A tube sheet is a critical component in heat exchangers, boilers, and similar equipment that involve the flow of fluids through tubes. Tube sheets may be made from durable materials to withstand high temperatures, pressures, and potential corrosive environments.
Existing paradenser tube sheet design necessitates the use of brazing techniques involving soft, hard, and silver solder. This method possesses a high potential for leaks due to the intricate brazing methods required within confined spaces. Over time, soft solder flux, composed of corrosive chlorides, degrades the metal surfaces it contacts, leading to significant leak risks and structural failures.
A paradenser tube sheet design is needed to eliminate the induction brazing process. By doing so, the dependency on soft solder flux is removed, thus simplifying the assembly process and enhancing the reliability of the paradenser tube sheet.

Existing paradenser tube sheet design necessitates the use of brazing techniques involving soft, hard, and silver solder. This method possesses a high potential for leaks due to the intricate brazing methods required within confined spaces. Over time, soft solder flux, composed of corrosive chlorides, degrades the metal surfaces it contacts, leading to significant leak risks and structural failures.
Embodiments disclosed are directed to a tube sheet redesign for paradenser liquid cooling product. The redesign aims to eliminate the induction brazing process entirely. By doing so, it removes the dependency on soft solder flux, thus simplifying the assembly process and enhancing the reliability of the product. This redesign solution eliminates the risk of material breakdown caused by the corrosive nature of soft solder flux, thereby enhancing the durability and performance of the paradenser tube.
For example, this redesign solution may incorporate sanitary connections that helps to eliminate the need for traditional brazing processes. Additionally, this redesign may involve the use of stainless steel fittings, which offer superior longevity and reliability. Embodiments disclosed will improve the overall product quality by minimizing potential leak points, reducing the likelihood of leaks associated with hot brazed joints, and enhancing the longevity and reliability of the product.
FIG. 1 illustrates a portion of a traditional vapor compression cooling system, utilizing a paradenser in the place of a conventional condenser. In FIG. 1, a vapor compression cooling system 100 includes a paradenser 110. A paradenser may include a series of condensers, depicted in FIG. 1 as condensers 110a, 110b, and 110c. In order to maximize the efficiency of the paradenser and the vapor compression system as a whole, the system is plumbed such that a manifold 140 is adapted to route cooling fluid through one or more of condenser 110a, 110b, or 110c in paradenser 110.
A control unit 180 may be adapted to control the manifold 140 such that cooling fluid is routed to the condensers as needed to optimize system capacity and/or to match the heat load generated by the space that is being cooled. The control unit 180 can direct cooling fluid flow through first fluid flow line 102 when condensers 110b and 110c are not required to reject heat from the refrigerant. The control unit 180 can direct additional cooling fluid flow through second fluid flow line 104 when condenser 110c is not required to reject heat from the refrigerant. Finally, control unit 180 can direct cooling fluid flow through first cooling fluid line 106 when all three condensers of the paradenser are needed to reject heat from the refrigerant. For example, if the system needed to reject more heat from refrigerant (based on the transduced temperature or pressure of the working fluid), the control unit 180 would direct cooling fluid through condenser 110c and condenser 110b. As more heat rejection was necessary, control unit 180 may additionally direct cooling fluid through condenser 110a. As more cooling fluid flows through more condensers, more heat can be rejected from the refrigerant.
FIG. 2 illustrates a perspective view of an exemplary embodiment of the paradenser tube sheet design referenced above. FIG. 2 provides a top-side perspective view of a paradenser tube sheet design, in accordance with embodiments described herein. As shown in FIG. 1, a piping system 200 includes the following components or parts: a connector 202, a seal 206, a tube sheet assembly 208, an inlet/outlet port 210, a main tube body 212, and internal tubes 214.
In FIG. 2, the connector 202 is configured to direct the flow of fluid within the piping system 200. For example, as shown in FIG. 2, in some embodiments, the connector 202 may be an elbow connector that serves to change the direction of the fluid flow within the piping system 200. The fluid may be redirected at a specific angle (e.g., 90°). This redirection can help in fitting the piping system into a confined space, navigating around obstacles, or connecting different components in an efficient layout. In some embodiments, other types of connectors (e.g., straight connector, tee connector, cross connector, etc.) may be used to accommodate the needs of the piping system 200.
As further depicted in FIG. 2, the tube sheet assembly 208 includes a substantially flat plate and a plurality of apertures extending through the plate from a first side of the plate to a second, opposing side of the plate. Flat is used herein refers to the shape and surface of the plate of the tube sheet assembly 208, which is primarily level, even and smooth across its surface, lacking any significant unevenness.
The plurality of apertures may be drilled through the plate of the tube sheet assembly 208 and sized to accept a series of tubes (e.g., the internal tubes 214) inside of an enclosed tubular pressure vessel (e.g., the main tube body 212), also referred to as shell and tube heat exchangers. For example, the plurality of apertures may be configured to accommodate and secure a plurality of tubes that extend internally along a length of the tubular pressure vessel of a liquid cooling system, where the plurality of tubes and the tubular pressure vessel are configured to enable transfer of heat from one fluid to another fluid.
Further, in some embodiments, the plurality of apertures of the tube sheet assembly 208 may be arranged in a specific pattern, allowing the internal tubes 214 to penetrate the tube sheet assembly 208 in multiple places to allow the fluid within these tubes to flow in and out of the heat exchanger. Further, the tube sheet assembly 208 is further configured to maintain separation between the fluid flowing through the internal tubes 214 and any external fluid in the main tube body 212. For example, the fluid flowing through the internal tubes 214 within the main tube body 212 exchanges heat with the fluid that flows into the main tube body 212 but flows past the outside of the internal tubes 214 exchanging the heat with the tube fluid.
In FIG. 2, the inlet/outlet port 210 is configured to allow the entry or exit of fluid (e.g., cooling fluid). The inlet/outlet port 210 may be connected to another portion of the piping system 200 (not pictured in FIG. 2) to facilitate the flow of fluid into or out of the piping system 200.
Also, in FIG. 2, the main tube body 212 is configured to house the fluid flow and support the internal tubes 214. For example, the main tube body 212 is connected to the tube sheet assembly 208 and houses the internal tubes 214 that extend internally through the main tube body 212. Further, in FIG. 2, the internal tubes 214 may be configured to allow for the flow of a cooling fluid through a paradenser cooling product or heat exchanger.
In FIG. 2, the seal 206 is configured to ensure a tight seal between adjoining parts to prevent leaks. As shown in FIG. 2, the seal 206 is placed between the sanitary connection 204 and the tube sheet assembly 208. The tube sheet assembly 208 is configured to hold and support the internal tubes 214 extending from the main tube body 212.
The piping system 200 of FIG. 2 may function by the fluid entering the piping system 200 through the inlet/outlet port 210 connected to external piping. Fluid may flow through the main tube body 212 and into the internal tubes 214, where heat exchange occurs. The internal tubes 214 may be held securely by the tube sheet assembly 208. The flow direction may be controlled by the connector 202 and the seal 206 may ensure a leak-proof and hygienic assembly. The fluid may then exit the piping system 200 through another port or may continue through another section of the piping system 200.
FIG. 3 illustrates a perspective view of an exemplary embodiment of a tube sheet assembly referenced above in FIG. 2. FIG. 3 provides a top-down perspective view of the tube sheet assembly 208 in FIG. 2, in accordance with embodiments described herein. As shown in FIG. 3, the tube sheet assembly 208 includes the following components or parts a substantially flat plate 302 and a plurality of apertures 304. The tube sheet assembly 208 may be made from a material (e.g., stainless steel) that provides structural integrity and resistance to corrosion.
As further depicted in FIG. 3, the plate 302 assumes a substantially circular structure. However, in other embodiments, the plate 302 may assume any shape (e.g., a square, a rectangle, a triangle, an oval, etc.) needed to accommodate interfacing with a heat exchanger.
The plurality of apertures 304 may be configured to accommodate a plurality of tubes (e.g., the internal tubes 214 in FIG. 2). As depicted in FIG. 3, a layout of the plurality of apertures 304 on the plate 302 are arranged in a circular pattern, where the layout includes a central aperture and a ring of apertures surrounding the central aperture. In some embodiments, the ring of apertures may be equally spaced apart forming a circular ring around the central aperture. In some embodiments, as depicted in FIG. 3, the ring of apertures may include six apertures equally spaced apart forming a circular ring around the central aperture. This configuration provides an even distribution of tubes across the surface of the plate 302 of the tube sheet assembly 208, optimizing for fluid flow and heat exchange efficiency.
FIG. 4 provides a cross-sectional view along the line A-A of FIG. 3, illustrating the structural configuration of the tube sheet assembly 208 including the sanitary flange fitting 306 and the positioning of tubes within the plurality of apertures 304. For example, sections 402 in FIG. 4 align with the center apertures of the plurality of apertures 304 in FIG. 3. FIG. 4 shows the sanitary flange fitting 306 in cross-section, representing the position and connection of the sanitary flange fitting 306 to the tube sheet assembly 208.
In some embodiments, the sanitary flange fittings 306 may be configured to connect to or attach to the main tube body 212. In some embodiments, the sanitary flange fitting 306 may be configured to connect to or attach to the connector 202. In some embodiments, the sanitary flange fitting 306 may be configured to connect to or attach to a manifold that connects multiple input and output lines, allowing for the distribution or collection of fluids or gases. The sanitary flange fitting 306 is configured to enable a hygienic and leak-proof seal between sections of the piping system 200.
Moreover, the sanitary flange fitting 306 may be configured to be positioned around the periphery of the plate 302 of the tube sheet assembly 208 and configured to connect the plate 302 to an inner circumference of the main tube body 212. The sanitary flange fitting 306 may be further configured to provide a hygienic and secure connection between the tube sheet assembly 208 and a component of paradenser liquid cooling product or a heat exchanger (e.g., the main tube body 212). This may prevent contamination and ensure leak-proof seals. In some embodiments, the sanitary flange fittings 306 may be configured to provide a leak-proof connection with adjoining pipes or systems and ensure a secure and contamination-free seal to maintain the integrity of the fluid flow within the piping system 200.
In some embodiments, the sanitary flange fitting 306 is made from a stainless steel. In some embodiments, the sanitary flange fitting may be welded using a Tungsten Inert Gas (TIG) welding process.
FIG. 5 provides a perspective view of the bottom of tube sheet assembly 208, in accordance with embodiments described herein. As shown in FIG. 5, the tube sheet assembly 208 includes a central aperture 502 and a ring of apertures 504 surrounding the central aperture 502.
As further shown in FIG. 5, the tube sheet assembly 208 further includes grooves 602 that are long and narrow indentations built into the tube sheet assembly 208 and are configured to allow another material or part to move within the grooves 602 and be guided by the grooves 602.
