Description

Technical area

With known heat exchangers, attempts have been made to solve the main problems in connection with heat transfer by using different means for. to improve the heat exchange effect, largely according to the following overview:

Each further improvement step will generally increase the price of the heat exchanger due to the complicated manufacturing of materials, so a compromise between performance and price must be found.

Heretofore, prior inventors have sought to optimize the heat transfer capability of a heat exchanger by varying the above means to satisfy particular applications. However, in applications requiring low flow resistance for the flowing medium, known heat exchangers have low efficiency due to their construction. Some devices use heat-conducting plates or fins that project into a first medium that is attached to a partition that separates the second, different medium. These devices have a large surface area in contact with the first medium, but not with both media. Other devices, where one seeks to overcome flow resistance, have the partition formed in a material, with fins on both sides of this. These devices are expensive to manufacture and heavy. Additional devices improve efficiency by passing fins through the partition, whereby the fins partially extend into both media. This reduces contact resistance, as the fins are continuous. In most of the above-mentioned devices, the fins are aligned and attached parallel to. the flow direction of the medium. This provides the least turbulence in the medium, at the same time as

it maintains a large surface contact in the medium. In order to

to increase the efficiency of this type of heat exchanger, however, more fins must be used, which increases flow resistance and manufacturing costs.

It is therefore a main purpose of this invention to provide a design of fins which extend both internally and externally through a partition which forms an internal chamber, whereby a low flow resistance for the medium in the chamber is avoided. Another purpose of this invention is to provide fins with larger exposed surface areas, constructed of highly heat-conducting materials so positioned that they sequentially and directly hit the flowing medium while maintaining a low flow resistance. Yet another purpose of the invention is to provide a cumulative heat storage and transfer capability in connection with the mass of the heat conduction fins. Another object of the present invention is to provide a design of highly heat-conducting fins which project into a flowing medium whereby higher heat exchange is achieved by optimizing the turbulence of this medium. Another purpose of this invention is to provide a stepwise, gradually increasing heat exchange in order to optimize the temperature gradient between the two heat exchange media. A further object of this invention is to expand the cavity in which the medium flows. Another purpose of this invention is to provide a construction that uses a minimum of expensive, highly heat-conducting materials only where it is desirable to optimize heat exchange. Yet another object of this invention is to provide a structure that can be easily expanded by placing additional sections of the invention in series for additional heat accumulation and exchange. Yet a further object of the invention is to provide a suitable means of easy assembly for an intended application. Another object of this invention is to provide a heat exchanger of new construction which is simple and cheap to manufacture or reproduce. A further object of the present invention is to provide such a heat exchanger which is light and suitable for use in a number of applications.

Description of the invention

The present invention is based on a heat exchanger which is of simple and easily reproducible construction, with consequent low manufacturing costs, where a dividing wall, which forms a compartment and separates two media, has a number of highly heat-conducting fins which project out and through the entire width of and generally to the center of the cubicle, thereby standing perpendicular to the internal medium flow and partially extending into both media whereby the fins become a heat link between the two media. Another characteristic feature of the invention is the use of materials with different thermal conductivity. The above enclosure is constructed from a material with a lower thermal conductivity than the fins, which are made from a material with a very high thermal conductivity. The use of different materials will further guide the heat exchange between the two media and limits the use of expensive, highly conductive materials.

In another embodiment of the present invention, an outer compartment encloses the aforementioned compartment, whereby the outer medium can be circulated past the fins extending from the inner compartment which is in a direct thermal connection between the two media.

This new invention, which uses many techniques to increase heat exchange, has the following combined advantages: 1. A very low flow resistance for the flowing medium. 2. The use of materials with different thermal conductivity to direct the heat transfer to desired areas in order to reduce the external heat loss of the heat exchanger, as in units constructed from a single material, and to reduce the unit cost by using expensive materials with high thermal conductivity only where it is desirable to optimize heat exchange. 3. Cavity expansion for the internal flowing medium so that it can move freely while interacting with the fins to have an increased surface contact duration with the highly conductive fins for extended heat exchange. 4. In that the extent of each fin, which is formed in one solid piece, extends into two separate media by protruding through the partition separating the two media, elimination of most losses in connection with is achieved. contact resistance, as in heat exchangers with fins attached to the partition wall. 5. Each fin has a large exposed surface area against the two more.... dies, which provides a direct shock effect and increased turbulence for

better heat exchange.

6. Each fin is mounted perpendicular to the flow direction of the flowing medium and thereby creates a direct shock effect and increased turbulence for improved heat exchange. 7. The arrangement of multiple fins positioned in a laterally offset manner relative to each other causes the internal medium to flow in a serpentine pattern sequentially impinging on each successive fin without weakening the flow mass. The advantage of this arrangement, especially when it is combined with materials of different thermal conductivity, is instantaneous compression and retention of the medium upon impact with each fin and a stepwise, gradually increasing heat exchange. In practice, the fins closest to the source medium inlet will assume a high temperature, while towards the outlet they gradually decrease in temperature. The result is an increased heat exchange when there is a higher temperature gradient between the fins and the receiving medium, this advantage being achieved by using the arrangement with laterally offset fins or counterflow techniques. Another advantage of this arrangement is a vertical suction caused by the heated fins in the inner compartment. 8. The length of the heat exchanger can be easily varied, which also changes the number of fins or heat transfer stages. Therefore, depending on the desired degree of heat exchange, the length of the unit can be easily selected and easily achieved just by adding additional sections. 9. The fins that extend into the external medium can interact with different media and flow directions of these media, e.g. cross flow, counter flow, etc. 10. By increasing the mass of the fins, this heat exchanger begins to accumulate heat in the fins to thereby form a means of heat storage and subsequent dispersion. 11. The whole heat exchanger is easy to mass produce, it is cheap, compact in size, light in weight, and flexible in application.

The later described embodiments of this invention are particularly suitable for applications where problems have previously plagued the industry. The current exhaust gas heat recovery exchangers suffer from poor performance and high cost, which has brought them into disrepute among the general public. This is mainly due to their pipe construction which does not provide sufficient impact surface area and turbulence for the escaping hot gases. In order to solve these problems, the application of generally known techniques will be limited by regulations that require very low flow resistance for the exhaust gases. However, these problems have been solved with the present invention and experiments have shown that the present invention, with its low costs, far exceeds the performance of even the most highly regarded and expensive units on the market today. Another special application where known heat exchangers have low performance is in the field of earth pipes. These devices, which consist mainly of brick pipes, saturate the closely surrounding soil with heat as a result of their lack of efficient heat exchange with the surrounding medium. With the present invention, the utilization of highly heat-conducting fins, with large exposed surface areas that extend far into the surrounding medium, will spread the heat far away from the pipe. By which exchange of much larger amounts of heat can be achieved, for cheap cooling of brines. A special reduction in power consumption is achieved when this invention's ground pipe is used in connection with heat pumps. A further application where the state of the art is generally unsatisfactory is domestic and commercial hot water heaters of the combustion type, where a large part of the heat energy produced by burning fuel disappears through the venting channel. The present invention is used internally on water heaters, where the heated gases in the venting duct communicate with protruding, heat-conducting fins arranged in the duct, and capture this normally wasted heat, as it is led directly into the water in the tank, thereby reducing the unit's fuel consumption. Another application of this invention is on passive solar walls, e.g. thrombus walls. These walls have been subject to increasing popularity as a result of rising energy costs. However, without a means of efficient conduction of the heat energy into the wall, it takes a long time before the wall is completely saturated with heat, which consequently reduces their

efficiency. With the present invention embedded inside such mass walls, with. highly heat-conducting materials sticking through to the wall's guide plate coated exterior, the solar heat absorption, as well as the solar heat transfer ability, is increased due to the location of the invention, which provides a conducting means inside the wall, with openings for intake of room air and discharge of heated

air for heat dissipation.

In applications in connection with solar thermal energy such as flat plate collectors, there is a disadvantage in that the conductive plate is only attached to the outside of a conduit or pipe. The pipe and collector plate are constructed from the same highly heat-conducting material, and welded or pressed together to conduct the solar thermal energy to the liquid in the conduit pipe. The present invention has several advantages in connection with flat plate solar thermal energy collectors, as the highly heat-conducting plates extend completely through the conduit or pipe, this pipe separates into two halves, which are attached to the plate by means of flanges located on the edge of each tube half. This simple construction can be easily mass-produced, and provides a high heat transfer effect, and also reduces unit costs by not having to use highly heat-conducting materials everywhere.

The heat spreader according to the present invention, which takes advantage of the advantages of fins and differently conductive materials, comprises: a first element or housing with a low thermal conductivity, into which strongly heat-conducting fins are inserted or pressed, these fins directly cooling the first element by using heat-conducting fins which extend externally and largely beyond the first element in an external medium or surrounding atmosphere. An application of this invention to an oil pan or container in a carriage engine or transmission, or an electric transformer housing, or hydraulic fluid reservoir, forms an effective cooler for the oil therein. In this application, previous units have predominantly been constructed of the same material throughout, either with externally attached fins, or internal pipes attached to the container, thereby forming a radiator with a larger surface for heat dissipation. This works to a certain extent, even if failure of the elements still occurs as a result of heat build-up. When using fins with high thermal conductivity, which protrude through the container wall, communication with the hot oil, and the formation of a larger internal surface area, heat spread will occur at a more intense rate, as a result of the natural heat flow through the fins into the cooler , preferably under the movement of the surrounding atmosphere. As is also the case with bearings and housings that contain bearings, the heat build-up in connection with use and load will often accelerate bearing fatigue and breakage. Present invention incorporated in such a house, which contains a warehouse or which e.g. is a brake drum, acts as an efficient heat radiator, which projects largely into the surrounding atmosphere. The highly heat-conducting fins are embedded in the housing so that they communicate with and touch the hottest area of the element to be cooled, and project through this less heat-conducting barrier or housing into the cooler surrounding atmosphere, for

efficient heat dissipation.

Detailed description

The construction of the invention as used for the recovery of waste heat from flue gas or waste gas is generally best shown in the images fig. 1-6 which show the connection between the different parts. The term "chimney" is used here generally for the sake of clarity to include such devices and guiding devices as pipes, chimneys, flue gas ducts, etc. The term "oven" or "firing place" means all kinds of combustion heating devices, such as large furnaces, heaters, boilers, etc. which use drain or discharge channel lines. The term "room air" is used here in general to denote atmospheric medium either liquid or gas. which will be used for heating or cooling purposes.-

In fig. 1 is a waste heat recovery unit generally denoted by the letter A as an essential unit for the replacement of an existing section of an exhaust pipe and which is composed of an enlarged inner casing 1 and an outer casing 2 which is shown with a rectangular shape in this particular embodiment,

although a round, square, oval or other symmetrical or asymmetrical construction may be used. The inner casing 1 is connected to the outer casing 2 by means of two end plates 5 and thereby forms and seals outer chamber 14. End caps 7 mostly consist of lids with outgoing collars which are attached to the same and fit directly onto the existing exhaust pipe. The end caps 7 are attached to the inner casing 1 which forms the inner chamber 13. Heat-conducting fins 3 are inserted by pressure into the inner casing 1 through slits which are somewhat narrower than the thickness of the fins 3, whereby they seal the joints. The fins 3 extend over and project substantially into the outer chamber 14 and largely into the center of the inner chamber 13. Approximately half of the number of fins 3 are placed between and at an even distance from the other half of the number of fins 3 which is mounted on the opposite side of the inner casing 13. Thereby the fins 3 form a laterally displaced row as shown in fig. 6. This configuration increases to maximum turbulence with minimal resistance to the flow of the heated exhaust gases in the inner chamber 13 and forces the gases to remain essentially in one mass and then to impinge on each fin 3 whereby the gases instantly come-

is primed, enclosed and deflected to the following fin as the gases move along a serpentine pattern through the inner chamber 13, whereby the heat from the gases is transferred through the fins 3 to the outer chamber 14.

It is important to note that in the embodiments that will follow, the principles of operation, description and configuration of the fins 3 attached to the inner casing 1 will remain the same.

In fig. 5, room air is forced by means of a fan 6 through the inlet 16 into an outer chamber 14, is then circulated, upwards as it is in contact with the fins 3 which extend or cross the outer chamber 14 and then continue between air flow distributors 8 down towards the opposite side of the outer chamber 14, completing the U-shaped air flow pattern, - after which the air leaves the unit through the outlet 15 and the register 10. A ductwork can be attached to the outlet 15 as an alternative to spread the heated air according to the conditions.

The main body of unit A should preferably be made of materials that are less heat conductive, e.g. tin, iron, steel, etc. compared to the highly heat-conducting materials that form the fins 3, e.g. copper, aluminum and alloys. These fins 3 may have a refined surface, e.g. coated, corrugated, metallized or constructed in many physical configurations, e.g. cloth attachment, pointed, slanted, etc

Figs 3 and 4 show an associated fine cleaning apparatus to overcome surface failure and to maintain the efficiency of the heat transfer. Quite simply, it consists of a rod 4 which is guided through aligned precisely arranged guide holes 17 which are placed both in the inner and the outer casing 1 and 2, so that with the rods 4 pulled out manually the connected scraper blade 9 is pressed against the fins and cleans them over the entire width of the fin's 3 upper part. By manual operation of the scraper combination 9 and 4 which in sequence starts at the top scraper and then continues towards the second lowest fin, the waste is collected and finally removed when it is placed in a firing box of the assigned furnace. The scratch combination 9 and 4 rests against

and parallel to the inner casing 1 when in the closed position during normal use of the heat recovery device A;

If, however, both the upper and the lower surface of the fin 3 are to be cleaned, only a minor modification is necessary.

Furthermore, for proper operation when the heat recovery unit A is installed, a bimetallic thermostat 11 is provided which affects the fan 6 when a certain ambient temperature is present in the outer chamber 14. This feature combined with the control for the fan speed and the line switch 12 provides for proper operation of the waste heat recovery unit. Fig. 7 describes a further application of this heat exchanger, where the inner casing 1 is shown embedded in an underground medium 20, i.e. soil, mud or water. The room air that is present in the building 18 is sucked by a fan 6 through the inner casing 1 and transfers the heat of the room air to the colder underground medium by means of the row of heat-conducting fins 3 which are attached to the inner casing 1 and protrude through this . The inner casing 1 should preferably be made of a corrosion-resistant material, such as plastic, stainless steel or brick. The fins 3 should preferably be made of corrosion-resistant and highly heat-conducting material, such as copper, aluminium, bronze, alloys. The longitudinal extent of the fin 3 into the underground medium 20 is determined by this medium's thermal conductivity and saturation capacity. Fig. 8 describes a further application of this invention incorporated in a water heater. Heat-conducting fins 3 extend into the water 22 located in the tank 21 and project through the walls of and into the interior of the inner casing 1. The heated combustion products rise from the combustion chamber 20 and then collide with each of the successive heat-conducting fins 3 , whereby the heat contained in the gases is transferred through the fins 3 directly to the water 22 that surrounds the inner casing 1. The thermostat 11 regulates the temperature of the water 22 in the tank 21.

In another embodiment of the invention as a waste heat recovery unit which is shown in fig. 9, the unit utilizes the counter-flow effect between the two adjacent media to increase the heat exchange. This unit can be attached to a large furnace or heater by essentially replacing a section of the existing chimney with this unit. The medium, e.g. the room air, which is to be heated, is led by means of a fan 6 through an inlet on the top of the unit and then passes essentially the entire length of the outer chamber 14 and then leaves the chamber through an outlet port 15 which is covered with cloth or grid in a directed current determined by manual adjustment of a deflector 30. Fig. 10 illustrates the use of this invention as a vehicle heater and muffler combination similar in construction and operation to the device of fig. 1. The vehicle engine emits waste gases which pass through the existing exhaust manifold 24 and continue through the inner casing 1, where the gases successively impinge on the heat-conducting fins 3, whereby the heat from the gases is transferred to the fins 3 which conduct the heat to the outer chamber 14. The thermally conductive fins 3 are sealed, i.e. welded or glued to the inner casing 1 to prevent mutual poisoning and thereby provide safe and reliable operation. The fan 6 forces the air either from the passenger compartment or the outside to enter the inlet port 16 and the air is heated as it passes the row of fins 3 which are placed in the outer chamber 14. This heated air is then led through the outlet port 15 to the driver's cabin or the passenger compartment. The vehicle engine's waste gases are led out after they have been used through an end pipe connector 25 and out to the existing waste pipe. Fig. 11 shows an embodiment carried out as an oil cooler consisting of an oil cooler pan 2 3 of different heat-conducting materials. The materials in the construction of this unit are similar to the materials described for unit A in fig. 1. Patterns with highly heat-conducting fins 3 extend through the wall of the pan 2 3 and out into the outer atmosphere. The hot oil contained in the pan 23 is in direct contact with the row of the thermally conductive fins 3 and is cooled by means of the fins 3 by transferring heat from the oil to the external atmosphere which is preferably usable and which is in motion. The cut-through between the pan 23 and the fins 3 is supported in a conventional way. Fig. 12 shows an embodiment of a waste heat recovery unit which essentially forms a replacement section for an existing gas pipe or the like. and which uses a highly heat-conducting fin 26 to which two flanged pipe halves are attached on opposite sides forming an inner casing 1. To each end of the inner casing 1 and the fin device 26, and as shown extends along the entire length of the outer casing 2, devices are attached for placing the existing pipes, ducts etc. A fan 6 forces the room air into a chamber that is integral with the top of the unit, where the air is collected and distributed evenly downwards in the outer chamber 14, in which the room air absorbs heat contained in the fin 26 and the inner casing 1 before it is carried out to the lower chamber and out of the register 10. The material used in this construction is preferably similar to the material according to fig. 1. Fig. 13 shows new applications using different heat-conducting metals in connection with bearings, engine housings, coupling housings, etc. The figure shows the application together with a roller bearing 27 which is installed in a housing 28. The housing 28 is made of a material with low thermal conductivity compared to the highly heat conductive fins 26 which are embedded in the housing 28 and are in contact with the outer race of the bearing and protrudes radially from the housing. The heat energy generated in the bearing 2 7 is quickly conducted and spread out through the fins 26 to the surrounding atmosphere or medium. Fig. 14 shows an embodiment where radially protruding strongly heat-conducting fins 26, e.g. of copper, aluminium, brass or alloys is embedded in a brake drum 29 of weaker heat-conducting material, such as cast iron, steel, whereby the heat produced by friction braking forces in the brake drum 29 is conducted and spread away through the embedded fins 26 and to the outer atmosphere.

Although the descriptions presented above contain many special embodiments, these should not be considered as limitations of the scope of the invention, but as examples of preferred embodiments of the same. Rising fuel prices increase the maintenance requirements for heat exchangers. The particular applications indicated above and the embodiments shown in the drawings are examples of the versatile applicability of the invention.
