HEAT EXCHANGER WITH HEAT EXCHANGE CHAMBERS UTILIZING RESPECTIVE MEDIUM DIRECTING MEMBERS
A heat exchange chamber includes an inlet, an outlet and a plurality of walls defining a chamber interior. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of flow. Disposed within the chamber interior is a medium directing member, having an inclined surface, which diverts the medium from the initial flow direction so that it disperses within the chamber interior. Exposure to the contact surfaces provided by the chamber walls causes the medium to exchange heat with the chamber and the external environment. The medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plural sets of chamber and tube assemblies are arranged between manifolds to provide a heat exchanger.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to heat exchangers and, more specifically, to a tube and chamber apparatus for transporting heat exchange media.
2. Discussion of the Related Art
Heat exchangers are commonly utilized in systems where it is desired for heat to be removed. Typical basic heat exchangers are made of pipes, which channel heat exchanging media. Headers or manifolds are attached to each end of the pipes. These headers and manifolds act as receptacles for the heat exchanging media. The efficiency of the pipe heat exchangers is limited by the amount of surface area available for the transfer of heat.
To add more surface area, some heat exchangers, such as condensers, incorporate a “tube-and-fin” design. This type of heat exchanger typically includes flattened tubes having a fluid passing therethrough and a plurality of fins extending between the tubes. The fins are attached to the tubes to effectively increase the surface area of the tubes, thereby enhancing heat transfer capability of the tubes. A number of tubes and fins may be stacked on top of each other, which leaves a small opening to allow passage of air in between them. In another tube-and-fin design, the tube can be of a serpentine design, therefore eliminating the need for headers or manifolds, as the tube is bent back and forth in an “S” shape to create a similar effect. Typical applications of this type of heat exchanger, besides condensers, are evaporators, oil coolers, and heater cores. This tube-and-fin design is also utilized in radiators for automobiles. Outside of the automotive field, the tube and fin design is implemented by industrial oil coolers, compressor oil coolers, and in other similar applications requiring a higher efficiency heat exchanger.
In another effort to create a greater exchange of heat by increasing surface area, very thin flat tubes with intricate inner rib structures are utilized. This type of heat exchanger is similar to the tube-and-fin design, in that fins are combined with the flat tubes, but in this particular type of heat exchanger, the flat tubes contain intricate internal chambers formed by the inner rib structures. These inner rib structures help to increase the heat exchanging performance of the heat exchanger. To further improve heat transfer efficiency, the tube thickness is made thinner. As a result, the parts are lighter in weight, which in turn makes the overall heat exchanger lighter in weight. However, the pressure resistance is reduced, and the thinner tubes are more prone to damage. Also, the assembly process is complicated because of the fragile nature of the parts. In addition, the internal chambers are prone to plugging during the manufacturing process, particularly if a brazing process is utilized. The complexity of the extruding process potentially results in higher costs and higher defect rates. Also, by utilizing internal chambers within the flat tubes to help disperse heat, the overall cost for the heat exchanging system will be higher because a higher powered compressor may be necessary to move the heat exchanging medium through the smaller openings of the tubes. Conversely, if a higher powered compressor is not utilized, then additional tubes will be necessary to obtain the desired heat exchanging performance because the smaller tubes reduce the flow of the heat exchange media significantly. The additional tubes will increase the overall cost for the heat exchanging system. Currently, this type of heat exchanger is used in applications requiring high heat exchanging capabilities, such as automotive air conditioner condensers.
A variation on the tube-based heat exchanger involves stacking flat ribbed plates. When stacked upon each other, these ribbed plates create chambers for transferring heat exchanging media. In essence, this type of heat exchanger performs substantially the same function as tube-and-fin type heat exchangers, but is fabricated differently. This type of heat exchanger is commonly implemented by contemporary evaporators.
SUMMARY OF THE INVENTIONThe present invention is an enhanced tube for heat exchanging applications including a flow tube and a chamber. The flow tube connects to the chamber. One end of the flow tube may connect to a header or a manifold. Heat exchange media flows from the header or the manifold into the flow tube. The heat exchange media then flows into the chamber. The heat exchange media then flows from the chamber into another flow tube, which is connected to another header or manifold.
In an embodiment of the present invention, the flow tube and the chamber for a heat exchanger are provided, for example, for a condenser, evaporator, radiator, etc. The heat exchanger may also be a heater core, intercooler, or an oil cooler for an automotive application (i.e., steering, transmission, engine, etc.) as well as for non-automotive applications. An advantage of the present invention is that the heat exchange media contact surface area for .radiating heat is greater over a shorter distance than that of a conventional heat exchanger. Therefore, the efficiency of the heat exchanger is increased. Another advantage of the present invention is that the overall length and weight of the enhanced tube for heat exchanging applications may be less compared to a conventional heat exchanger, which in turn provides for a lower overall cost as less raw material and less packaging is necessary. Furthermore, the smaller footprint of the present invention lends itself to be used in applications where space is limited. Yet another advantage of the present invention over a conventional heat exchanger is that the manufacturing process may be simpler because the present invention requires less fragile components and less manufacturing steps. The entire unit may be brazed together, or any portion of the unit can be brazed first, and then additional components may be brazed or soldered together.
In another embodiment of the present invention, more than one chamber may be used, which will further increase the surface area of the enhanced tube for the heat exchanger. Also, a first chamber may be connected directly to another chamber.
In yet another embodiment of the present invention, the tube size may vary between the chambers, and if more than one chamber is used, the chamber size may vary from one chamber to the next.
In a further embodiment of the present invention, each chamber may disperse heat exchanging media throughout the chamber, which further enhances the heat exchanging capabilities of the present invention. Also, each chamber may also mix heat exchanging media.
In yet a further embodiment of the present invention, each chamber may include a medium directing member and medium redirection members that direct and redirect heat exchanging media in particular directions through the chamber.
In another embodiment of the present invention, the inner surface of the tube may feature indentations to increase the surface area. Also, in yet another embodiment of the present invention, the inner surface of the chamber may also feature indentations to increase the surface area. In a further embodiment of the present invention, the redirection member may also feature indentations.
In other embodiments of the present invention, the tube and chamber combination may be repeated, and based on a particular application, there may be multiple tube and chamber assembly rows. Several of the tube and chamber units may be attached to a header or a manifold. There may be a plurality of tube and chamber units arranged in a row that are attached to a header or a manifold to enhance the overall performance of the heat exchanger.
In some embodiments, the chamber is of a greater diameter than the inlet and the outlet of the chamber. In other embodiments, the chamber is of a greater diameter than the inlet of the chamber, but may be the same diameter as the outlet. Alternatively, in yet other embodiments, the chamber may be of a greater diameter than the outlet of the chamber, but may be the same diameter as the inlet.
In yet some other embodiments, the chamber has at least one greater dimension than the tube. For instance, the chamber may have a greater fluid capacity, circumference, or surface area. The ratio of a particular dimension between the tube and the chamber may be 1:1.1; 1:1.5; or any other suitable ratio.
The tube and the chamber may be made of aluminum, either with cladding or without cladding. The tube and chamber may also be made of stainless steel, copper or other ferrous or non-ferrous materials. The tube and chamber may also be a plastic material or other composite materials.
The tube and chamber may be manufactured by stamping, cold forging, or machining. The tube and chamber may be manufactured as one piece or may be manufactured as two separate pieces.
Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood after reading the subsequent description taken in conjunction with the accompanying drawings.
Referring to the drawings and in particular
In another embodiment of the heat exchanger 100, the heat exchanger 100 may be used in a reversed method. Instead of the heat exchanger 100 being used in an environment where heat is transferred from the heat exchange media 50 to the surrounding environment of the heat exchanger 100, the heat exchanger 100 may be used to increase the temperature of the heat exchange media 50 flowing inside the present invention. For example, water of an ambient temperature may flow through the tube 10 and the chamber 20 of the heat exchanger 100, where the environment surrounding the heat exchanger 100 is of a higher temperature than that of the water. Continuing with this example, the heat from the environment surrounding the heat exchanger 100 is transferred to the water, thereby increasing the temperature of the water. An example of this embodiment, which is not intended to be limiting, would be a water heater.
