Description

Heat exchanger for a machine Stirling cycle cooling, exchanger body heat, and manufacturing method of the exchanger body hot.

Technical field

The present invention is related to a member of a heat exchanger, such as an absorber of heat or heat eliminator, provided in a cycle refrigerator of Stirling, of an element of the heat exchanger for its use in said heat exchanger member, and with a manufacturing method of said exchanger member of hot.

Art background

\hbox{regenerador 3.}

A typical configuration of a Stirling cycle cooler of the free piston type that exploits the Stirling cycle will be described first. Figure 29 is a diagram schematically showing a section, as seen from the side, of a Stirling cycle cooler of the free piston type. Within a cylinder 1, a heat absorber 2 that acts as a low temperature part, a regenerator 3, and a heat eliminator 4 acting as a high temperature part, are arranged in this order. The heat absorber 2 and the heat eliminator 4 are each constructed as a heat exchanger member composed of a tubular body 21 or 41, having a heat exchanger element 22 or 42, mounted on an inner surface thereof in an extreme. Within cylinder 1, elements 22 and 42 are each adjacent to the

 \ hbox {regenerator 3.} 

Inside cylinder 1 they are arranged also a displacer 6 firmly mounted at one end of a connecting rod 5 of the displacer, and a piston 7 through which it is placed connecting rod 5 of the displacer. The other end of connecting rod 5 of displacer is connected to a spring 8. Inside cylinder 1, the displacer 6 and piston 7 create an expansion space 9 in the heat absorber 2 and in compression space 10 in the heat eliminator 4. The expansion space 9 and the space of compression 10 communicate with each other through regenerator 3, and therefore they form a closed circuit.

The way to operate will be described below. of this free-piston type Stirling cycle cooler. The piston 7 is made to have a reciprocating motion at axis length of cylinder 1 with a predetermined period by an external heat source, such as a linear motor (not shown). Compression space 10 is filled in advance with a Work gas, such as helium.

As piston 7 moves, the working gas in the compression space 10. This causes the working gas circulate through element 42 of the exchanger of heat, then through the regenerator 3 inside of expansion space 9 (as indicated by arrows A of strokes in the figure). Meanwhile, the working gas releases first heat in heat eliminator 4, by means of heat exchange generated as a result of compression with the outside air, and pre-cooling then as it passes through the regenerator 3, by the reception of the cold previously accumulated in the regenerator 3.

When the working gas circulates inside the expansion space 9, press displacer 6 to the right against spring 8. Thus, the working gas expands, and It generates cold. When the working gas expands to a certain degree, the resilience of the spring 8 presses the displacer 8 towards back in the opposite direction.

\hbox{pistón 7.}

As a result, the working gas in the expansion space 9 circulates through the element 22 of the heat absorber exchanger 2 and then through the regenerator 3 back to the compression space 10 (as indicated by the arrows A 'continuous stroke). Meanwhile, the working gas first absorbs heat in the element 22 of the heat exchanger, by exchanging heat with the outside air, and then is heated as it passes through the regenerator 3, by receiving the heat previously accumulated in the regenerator 3. The working gas again in the compression space 10 is then compressed again by the

 \ hbox {piston 7.} 

Through the repetition of this cycle of events, a cryogenic cold is obtained in the heat absorber 2.  In this case you will have more performance when the higher the amount of heat absorbed in element 22 of the heat exchanger heat absorber heat 2 and greater will be the amount of heat dissipated in the element 42 of the heat exchanger of the heat eliminator 4. This helps increase performance with which precools regenerator 3 and the performance with which preheats the working gas, and helping therefore to reduce the load on the regenerator 3, leading to a best cooling performance of the cycle refrigerator Stirling.

It will be described below with reference to the figure 30 the heat eliminator 4 acting as the member of the heat exchanger on the high temperature side of the Stirling cycle refrigerator described above. Be You will understand that, although the following description deals only with the heat eliminator 4 and its element 42 of the heat exchanger, heat absorber 2 acts as the exchanger member of heat of the low temperature side and its element 22 of the heat exchanger, being configured of the same shape.

As shown in Figure 30, this element 42 of the heat exchanger is constructed as a annular corrugated sheet 421 manufactured by forming a Corrugated iron material in a cylindrical shape. So that, element 42 of the heat exchanger has a surface steep, with a large number of 421a straight V-shaped grooves that extend axially with regular intervals.

In this case, the parts of element 42 of the heat exchanger protruding towards the center of the body 41 of heat eliminator 4 are referred to as funds 421b of the individual slots 421a, and the parts of element 42 of the heat exchanger protruding towards the inner surface of body 41 are referred to as tips 421c between each two adjacent slots 421a. The diameter of the circle formed by the uniform connection of all tips 421c together (i.e. the outer diameter of the annular corrugated sheet 421) is substantially equal to the internal diameter of the body 41. The body 41 and annular corrugated sheet 421 are arranged to be coaxial with each other.

The inner surface of the body 41 and the tips 421c of the annular corrugated sheet 421 are firmly fixed with adhesive or welded. Figure 31 is an enlarged view of a part of the annular corrugated sheet 421 as seen axially, and shows how it is fixed by an adhesive. In In this case, the adhesive 11 is applied first in fine form to the inner surface of the body 41, and then the sheet is inserted corrugated annular 421 inside body 41. Next, with the annular corrugated sheet 421 retained in the desired position for one moment, the adhesive 11 dries.

On the contrary, Figure 32 shows the shape in which the annular corrugated sheet 421 is fixed with welding. In this case, the annular corrugated sheet is first inserted 421 in body 41. Next with the annular corrugated sheet 421 retained in the desired position, weld 12 is applied in the part where the internal surface of the body 41 makes contact or becomes close with the tips 421c of the corrugated sheet cancel 421.

However, with this member of the exchanger conventional heat described above, joint fixation of its components with adhesive or by welding it is executed at hand. So, this process requires a lot of work and time, hindering the improvement of productivity and the reduction of manufacturing costs. Additionally, the exchanger member of heat thus manufactured is predisposed to variations in the quality, specifically in the performance of the exchanger heat, and therefore I tend to lack stability and reliability.

Additionally, since the refrigerator of Stirling cycle is used for a long period of time, if annular corrugated sheet 421 is damaged, it will be impossible to disassemble and replace it easily. This adds an economic problem. for the user in the case of repair, and being contrary to the general trend towards the recycling of resources in view of the Global environment An example of an exchanger member Conventional heat is shown in the document JP9-86526A.

Exhibition of the invention

Fixing the annular corrugated sheet and the inner ring-shaped member helps increase the area of contact between them and therefore to enhance conductivity of heat. Additionally, its integration makes manipulation of the heat exchanger element is easier, and makes possible by replacing the repair of the element of the heat exchanger. This makes the element of Heat exchanger be economical and recyclable. The integration bonding means are achieved, such as strong brazing or the conventional welding

A heat exchanger member is manufactured according to the present invention by inserting a heat exchanger element for a cycle refrigerator Stirling inside a hollow part of a tubular body. In this case, the internal diameter of the body can be made slightly smaller than the outer diameter of the exchanger element of hot. This makes it possible to fit the exchanger element of heat inside the body by snapping, that is, without hitting or welding. Additionally, at least one end of the body can be made to be conical, so that the thickness of the body wall becomes smaller towards said end along From the axis. This allows for easy insertion of the element of the heat exchanger inside the body.

Additionally, around the corrugated sheet annular, the projections can be formed in the form of waves in order that they are in intimate contact with each other and at regular intervals globally, with waveform depressions formed in the inner surface of the body, in order to spread axially and corresponding to the projections in the form of waves, to that when the heat exchanger element is inserted inside the body, the wave-shaped projections fit into Depressions in the form of waves. This prevents the element of heat exchanger can rotate out of position inside the body.

Alternatively, annular corrugated sheet It can be manufactured by forming a sheet linear corrugated, of which the most extreme sides of the grooves V-shaped inverted at both ends are longer than the sloping sides of the intermediate V-shaped grooves, within a cylindrical shape, then retaining the most extreme sides together, so that the surfaces of said sides more ends stay in contact with each other, and then fitting the resulting protruding part that forms on the tip of the sides more ends, to project radially out of the periphery outside of the annular corrugated sheet in a groove that forms in the inner surface of the body, to extend axially. This also prevents the heat exchanger element can rotate leaving its position inside the body.

The heat exchanger member can be manufactured, for example, by detachably locating one end of a tapered tubular guide member in the body, so that the internal diameter thereof at one end is substantially equal to the internal diameter of the body, and in which the wall thickness becomes smaller towards the other end, and then inserting the heat exchanger element for a Stirling cycle cooler into the body, by guiding it through the guide member axially from the other end of it. In the heat exchanger member manufactured in this way, when the annular corrugated sheet is guided through the guide member, its peripheral shape changes, increasing the area of contact with the internal surface of the body. This enhances the heat conduction performance of the annular corrugated sheet, and making it possible to make a heat exchanger member with an excellent degree of heat exchanger performance.
hot.

The heat exchanger member agreed with the invention it is manufactured by inserting the element of the heat exchanger described above for a refrigerator Stirling cycle in a hollow part of the tubular body. In this case, the internal diameter of the body becomes slightly smaller than the outer diameter of the heat exchanger element. This makes it possible to fit the heat exchanger element inside of the body, by snapping, that is, without effecting glued or welded. Additionally, at least one end of the body can be tapered, so that the wall thickness of the body becomes smaller than towards said end along the axis. This allows for easy insertion of the element of the heat exchanger in the body.

The aforementioned annular corrugated sheet is easily manufactured by forming a corrugated sheet line, having adjacent V-shaped grooves, within a cylindrical shape, and then coupling the outermost side of the V-shaped groove at one end of the linear corrugated sheet with the most extreme side of the inverted V-shaped groove in the other end of it.

Alternatively, the annular corrugated sheet is manufactures by forming a linear corrugated sheet, which have adjacent V-shaped grooves, in a cylindrical shape, and then jointly coupling the most extreme side of the groove in V shape at one end with linear corrugated sheet and side more end of the V-shaped slot inverted at the other end thereof, by performing an electric welding of points on the surface of said more extreme sides.

Alternatively, the annular corrugated sheet is manufactures by forming a linear corrugated sheet, which it has contiguous V-shaped grooves, in a cylindrical shape, and then jointly coupling the outermost side of the groove in V shape at one end of the linear corrugated sheet and the most side  end of the V-shaped groove inverted at the other end by joining the surfaces of said outermost sides jointly.

From now on, the embodiments of the present invention with reference to drawings. In the following description, the members who have the same names as in the conventional examples shown in the Figures 29 to 32 are identified with the same numerals of reference. Additionally, in the following descriptions, although it is only the heat eliminator 4 and its element 42 of the heat exchanger, the explanations given regarding their configurations, selection of materials for consultation of the members, possible changes in their design, and others aspects thereof are also applicable to the heat absorber 2 and its element 22 of the heat exchanger. Consequently, to unless otherwise indicated, in the following descriptions, the heat eliminator 4 and its element 42 of the heat exchanger they are used interchangeably with heat absorber 2 and its element 22 of the heat exchanger.

The first embodiment will be described later of the invention. Figure 1 is an external perspective view of heat eliminator 4 serving as a member of the heat exchanger in this embodiment. Figures 2A and 2B are  an exterior perspective view and a perspective view exploded, respectively, of element 42 of the heat exchanger heat of heat eliminator 4. Figure 3 is a plan view enlarged part of the heat eliminator, as seen axially

This element 42 of the heat exchanger is composed of an annular corrugated sheet 421 and a member 422 in internal ring shape. The corrugated annular sheet 421 is manufactured by forming a corrugated sheet material in a cylindrical shape with the individual grooves 421a of the same parallel to the axis of the cylindrical shape. The member 422 in Internal ring shape is a cylindrical member manufactured with a material that has excellent thermal conductivity.

First, the method of manufacture of the 421 annular corrugated sheet used in this realization. Figures 6A to 6C show the procedure of manufacture of annular corrugated sheet 421. Figure 6A is a plan view of a 420 linear corrugated sheet, where the Figure 6B is an enlarged plan view of the corrugated sheet Linear 420 in a rounded state with both ends thereof together, and Figure 6C is an enlarged plan view of the sheet annular corrugated 421 in its finished state.

As Figure 6A shows, the sheet Linear corrugated 420 has contiguous grooves 420e that have a V-shaped section each. At one end of the sheet Linear corrugated 420 is a V-shaped groove 420a, and at the other end of it is a slot 420b in inverted V shape. The outermost side 420c of slot 420a and the outermost side 420d of the slot 420b are formed so that its length L1 is shorter than the length L of the sides inclined between the tips and the bottoms 420f and 420f of the slots 420e intermediate.

Linear corrugated sheet 420 is folded in the directions indicated by arrows F1 and F2 in figure 6A, in order to form it in a cylindrical profile. With more sides 420c and 420d ends contacted as shown in the Figure 6B, the outermost sides 420c and 420d hook together as shown in figure 6C, and therefore forming the annular corrugated sheet 421. Thus, according to the corrugated sheet annul 421 tends to return to its original linear state, the sides more external 420c and 420d hook each other through their traction, and therefore the annular shape of the sheet will be maintained annular corrugated 421. Reference numeral 421d represents the coupled part.

As shown in Figures 2A and 5, the inner ring-shaped member 422 is placed in contact with the inner periphery of the annular corrugated sheet 421, so that are coaxial with each other (that is, so that their axes match each other). In this case, the diameter of the circle formed for the uniform connection of all the bottoms 421b of the sheet corrugated ring 421 (i.e. the inner diameter of the sheet corrugated ring 421) is made to be substantially equal to outer diameter of the inner ring-shaped member 422.

The corrugated annular sheet 421 and the member in Inner ring shape 422 are joined together with a brazing metal 13 in the form of a ring. Specifically, such As Figure 2B shows, the brazing metal 13 is placed where the annular corrugated sheet 421 and the member make contact in the form of an inner ring 422 with each other, heating so that molten brazing metal 13 can circulate along the bottoms 421b of the annular corrugated sheet 421.

As a result, as shown in Figure 3, the brazing metal 13 is applied substantially in shape uniform in ear contact the annular corrugated sheet 421 and the inner ring-shaped member 422 with each other. To the harden the brazing metal 13, the corrugated sheet annular 421 and the inner ring-shaped member 422 are joined jointly and therefore integrating together. Instead of the brazing specifically mentioned above, you can Use a conventional or similar welding.

The element 42 of the heat exchanger described above is inserted into a body 41 shown in the Figure 1, so that they are coaxial with each other, and therefore thus manufacturing the heat eliminator 4. Element 42 of the heat exchanger is inserted into body 41 by means of the next mechanism. As shown in Figure 4, which is a outline in cross section of body 41 and element 42 of the heat exchanger, both ends of body 41 are conical, so that the thickness of the wall of the wall becomes smaller towards the ends along its axis (these parts are denominated as conical parts 41a).

Additionally, the outer diameter of the element 42 of the heat exchanger (i.e. the outer diameter of the annular corrugated sheet 421) R1 (= \ varphiB) is slightly less than the maximum internal diameter R2 (= \ varphiB + α1) of body 41 at both ends thereof, and slightly larger than the internal diameter R3 (= \ varphiB - α2 of body 41 in the position thereof between the conical parts 41a.

So, when item 42 of the heat exchanger is inserted into element 42 of the heat exchanger from one end thereof, the insert It requires a small force at the beginning. Since the diameter internal body 41 becomes gradually smaller until it reaches to be eventually smaller than the external diameter R1 of the element 42 of the heat exchanger, as element 42 is inserted of the heat exchanger, the force required to do this operation is gradually increased. In this way, element 42 of the heat exchanger can be easily inserted into the body 41.

In this case, since funds 421b of the annular corrugated sheet 421 are fixed to member 422 in shape of inner ring, the corrugated annular sheet 421 thus embedded inside body 41, where the internal diameter R3 is smaller than the external diameter R1 of the annular corrugated sheet 421, is carried to a state in which the slots 421a are pressed so that be more open, and this generates a resilient force that acts radially out.

Additionally, since the outer diameter R1 of the annular corrugated sheet 421 and the depth of the grooves 421a is constant along the axis, the resilient force mentioned above will press element 42 of the heat exchanger heat on the internal surface of the body 41 with a force uniform around in its entirety, and thus keeping it without deformation.

As described above, in this embodiment, the inner ring-shaped member 422 may be fixed in the desired position within the body 41 without the use of Adhesive or welding. This helps to simplify the procedure of manufacturing and reduce manufacturing cost, and also to stabilize the heat exchange performance of the member of the heat exchanger.

Additionally, when the annular corrugated sheet 421 is damaged, element 42 of the heat exchanger can removed and removed from body 41. This allows replacement easy as needed, and help to mitigate the problem economic of the user in the case of repair and to solve the  recycling problems.

Additionally, in item 42 of the heat exchanger used in this embodiment, the sheet annular corrugated 421 and the inner ring-shaped member 422, They are integrated together by brazing, welding  conventional, or similar, and thus showing better conductivity thermal than when left unintegrated. This helps increase heat exchange performance.

A second one will be described below. embodiment of the invention. Figure 7 is a plan view enlarged heat eliminator 4 of this embodiment, as observe axially. The heat eliminator 4 of this embodiment, Like the first embodiment described above, it is composed by an element 42 of the heat exchanger, comprising a annular corrugated sheet 421 and a ring-shaped member interior 422 welded inside it, and a body 41 inside of which element 42 of the heat exchanger is mounted hot.

First, the method of manufacture of the 421 annular corrugated sheet used in this realization. Figures 8A to 8C show the procedure of manufacture of annular corrugated sheet 421. Figure 8A is a plan view of the annular corrugated sheet 420, Figure 8B is a plan view of the 420 linear corrugated sheet in a state rounded with both ends in contact, and Figure 8C is a enlarged plan view of a part of the annular corrugated sheet 421 in its finished state.

As Figure 8A shows, the sheet Linear corrugated 420 has contiguous grooves 420e having a V-shaped section each. At one end of the sheet Linear corrugated 420 is a V-shaped groove 420a, and at the other end of it is a slot 420b in inverted V shape. The outermost side 420c of slot 420a and the outermost side 420d of the groove 420b are shaped that its length L2 be shorter than the length L of the sides inclined between the tips and the bottoms 420f and 420f of the slots 420e intermediate.

Linear corrugated sheet 420 is folded in the directions indicated by arrows F1 and F2 in figure 8A, in order to form a cylindrical profile. With more sides ends 420c and 420d brought to its junction as indicated in the Figure 8B, spot welding is performed on the parts of the surfaces of said outermost sides 420c and 420d, so that these surfaces join together while keep in touch with each other. In this way, the laminate is manufactured corrugated ring 421 as shown in Figure 8C.

As shown in Figures 2A and 7, the member 422 in the form of an inner ring is placed in contact with the inner periphery of the annular corrugated sheet 421, so that Be coaxial with each other. In this case, the diameter of the circle formed by the uniform connection of all funds 421b of the annular corrugated sheet 421 (that is, the internal diameter of the annular corrugated sheet 421) is made to be substantially the same to the outer diameter of the inner ring-shaped member 422

Corrugated annular sheet 421 and member 422 in the form of an inner ring they are joined together with a metal of ring brazing 13. Specifically, such as Figure 2B shows, the brazing metal 13 is placed in where the annular corrugated sheet 421 and the member 422 in the form of an inner ring, and heating so that molten brazing metal 13 flows along the bottoms 421b of the annular corrugated sheet 421.

As a result, as the Figure 3, brazing metal 13 is applied substantially evenly where the sheet makes contact with each other annular corrugated 421 and the inner ring shaped member 422. When the brazing metal 13 hardens, the corrugated sheet annular 421 and the inner ring-shaped member 422 are joined jointly and therefore being integrated. Instead of performing The brazing specified above, you can use the conventional welding or similar.

The element 42 of the heat exchanger before described is inserted into the body 41 shown in figure 1, of so that they are coaxial with each other, and therefore the heat eliminator 4. Element 42 of the heat exchanger It is inserted into body 41 by the following mechanism. Such as is shown in figure 4, which is a sectional outline of the body 41 and element 42 of the heat exchanger, both body ends 41 are conical, so that the thickness of the it becomes smaller towards the ends along the axis of the same (these parts are referred to as conical parts 41a).

Additionally, the external diameter of the element 42 of the heat exchanger (i.e. the outer diameter of the annular corrugated sheet 421) R1 (= \ varphiB) is made to be smaller slightly than the maximum internal diameter R2 (= \ varphiB + α1) of body 41 at both ends thereof, and slightly larger than the internal diameter R3 (= \ varphiB - α2 of body 41 in the position thereof between the conical parts 41a.

Thus, when element 42 of the heat exchanger inside the exchanger element of heat 42 from one end thereof, the insertion requires a Small pressure force at the beginning. Since the diameter internal body 41 gradually becomes smaller until eventually it becomes smaller than the external diameter R1 of the element 42 of the heat exchanger, as the element 42 of the heat exchanger, the force required to Doing this operation gradually increases. In this way the element 42 of the heat exchanger can be inserted easily inside the body 41.

In this case, since funds 421b of the annular corrugated sheet 421 are fixed to member 422 in shape of inner ring, the corrugated annular sheet 421 thus mounted on body 41, in which the internal diameter R3 is smaller than the external diameter R1 of the annular corrugated sheet 421, is brought to a state in which the slots 421a are pressed so make them more open, and this produces a resilient force radially out.

Additionally, since the external diameter R1 of annular corrugated sheet 421 and groove depth 421a are constant along the axis, the resilient force before mentioned press the element 42 of the heat exchanger on the internal surface of the body 41, with a uniform force around in its entirety and therefore keeping it in position. In this case, the annular corrugated sheet 421 and the shaped member of inner ring 422 are fixed together and therefore not being deformed

As described above, in this embodiment, the inner ring-shaped member 422 can set in the desired position within body 41 without the use of Adhesive or welding. This helps to simplify the procedure of manufacturing and reduce manufacturing costs, and also to stabilize the heat exchange performance of the member of the heat exchanger.

Additionally, when the annular corrugated sheet 421 is damaged, element 42 of the heat exchanger can be removed and removed from body 41. This allows for easy replacement as needed, and thus helps mitigate the economic problem to the user in the case of repair and to solve the problems Recycled

Additionally, in element 42 used of the heat exchanger in this embodiment, the corrugated sheet annular 421 and the inner ring-shaped member 422 is they are integrated together by brazing, conventional welding, or similar, and thus showing a better thermal conductivity than when left unintegrated. This helps to increase heat exchange performance.

A third will be described below. embodiment of the invention. Figure 9 is a plan view of a part of the heat eliminator 4 of this embodiment, as observe axially. The heat eliminator 4 of this embodiment, Like the first embodiment described above, it is composed by an element 42 of the heat exchanger, comprising a annular corrugated sheet 421 and an inner ring-shaped member 422 welded into it, and a body 41 within which The heat exchanger element 42 is mounted.

First, the method of manufacture of the annular corrugated sheet 421 used in this realization. Figures 10A and 10B show the procedure of manufacture of the annular corrugated sheet 421. Figure 10A is a plan view of the rounded corrugated sheet 420, figure 10B it is an enlarged plan view of the 420 linear corrugated sheet, in a rounded state with both ends joined, and figure 10C it is an enlarged plan view of a part of the corrugated sheet cancel 421 in its finished state.

As Figure 10A shows, the sheet Linear corrugated 420 has contiguous grooves 420e, having a V section each. At one end of the linear corrugated sheet 420 is a V-shaped slot 420e, and in the other end of it is a V-shaped groove 420b inverted The outermost side 420c of the groove 420a and the plus side external 420d of slot 420b are formed so that its length L3 is shorter than the length L of the sloping sides between the tips and bottoms 420f and 420f of the slots 420e intermediate.

Linear corrugated sheet 420 is folded in the directions indicated by arrows F1 and F2 in Figure 10A, in order to conform to a cylindrical profile, so that the outermost sides 420c and 420d are placed together (figure 10B). Then the surfaces of the outermost sides 420c and 420d, to which an instant adhesive of beforehand, they keep contact with each other for a moment so They stick together. In this way, the laminate is manufactured corrugated ring 421 as shown in Figure 10C. He reference numeral 421f represents the joined part.

As shown in Figures 2A and 9, the member in the form of an inner ring 422 is placed in contact with the inner periphery of the annular corrugated sheet 421, so that Be coaxial with each other. In this case, the diameter of the circle formed by the uniform connection of all funds 421b of the annular corrugated sheet 421 (that is, the internal diameter of the annular corrugated sheet 421) is substantially equal to the diameter outer of the inner ring-shaped member 422.

The corrugated annular sheet 421 and the member in inner ring shape 422 are joined together by a brazing metal 13 in the form of a ring. Specifically, such As Figure 2B shows, the brazing metal 13 is placed where the annular corrugated sheet 421 makes contact with each other and the inner ring-shaped member 422, and heating so that molten brazing metal 13 circulates along the bottoms 421b of the annular corrugated sheet 421.

As a result, as shown in the Figure 3, brazing metal 13 is applied substantially evenly in the contacting part of the sheet corrugated ring 421 and the inner ring-shaped member 422. When the brazing metal 13 hardens, the sheet corrugated ring 421 and the inner ring-shaped member 422 is join together and therefore integrate together. Instead of the brazing specifically mentioned above, you can Use conventional welding or similar.

The element 42 of the heat exchanger described above is inserted into a body 41 shown in the Figure 1, so that they are coaxial with each other, thus being manufactured therefore the heat eliminator 4. Element 42 of the heat exchanger is inserted into body 41 by means of the next mechanism. As shown in Figure 4, which is an outline in section of body 41 and element 42 of the heat exchanger, both ends of body 41 are conical, so that the thickness of it becomes smaller towards the ends along its axis (these parts are called as the conical parts 41a).

Additionally, the external diameter of the element 42 of the heat exchanger (i.e. the outer diameter of the annular corrugated sheet 421) R1 (= \ varphiB) is made to be smaller slightly than the maximum internal diameter R2 (= \ varphiB + α1) of body 41 at both ends thereof, and slightly larger than the internal diameter R3 (= \ varphiB - α2 of body 41 in the position thereof between the conical parts 41a.

Thus, when element 42 of the heat exchanger inside the exchanger element of heat 42 from one end thereof, the insertion requires a Small pressure force at the beginning. Since the diameter internal body 41 gradually becomes smaller until eventually it becomes smaller than the external diameter R1 of the element 42 of the heat exchanger, as the element 42 of the heat exchanger, the force required to Doing this operation gradually increases. In this way the element 42 of the heat exchanger can be inserted easily inside the body 41.

In this case, since funds 421b of the annular corrugated sheet 421 are fixed to member 422 in shape of inner ring, the corrugated annular sheet 421 thus mounted on body 41, in which the internal diameter R3 is smaller than the external diameter R1 of the annular corrugated sheet 421, is brought to a state in which the slots 421a are pressed so make them more open, and this produces a resilient force radially out.

Additionally, since the external diameter R1 of annular corrugated sheet 421 and groove depth 421a are constant along the axis, the resilient force before mentioned press the element 42 of the heat exchanger on the internal surface of the body 41, with a uniform force around in its entirety and therefore keeping it in position. In this case, the annular corrugated sheet 421 and the shaped member of inner ring 422 are fixed together and therefore not being deformed

As described above, in this embodiment, the inner ring-shaped member 422 can set in the desired position within body 41 without the use of Adhesive or welding. This helps to simplify the procedure of manufacturing and reduce manufacturing costs, and also to stabilize the heat exchange performance of the member of the heat exchanger.

Additionally, when the annular corrugated sheet 421 is damaged, element 42 of the heat exchanger can be removed and removed from body 41. This allows for easy replacement as needed, and thus helps mitigate the economic problem to the user in the case of repair and to solve the problems Recycled

Additionally, in element 42 used of the heat exchanger in this embodiment, the corrugated sheet annular 421 and the inner ring-shaped member 422 is they are integrated together by brazing, conventional welding, or similar, and thus showing a better thermal conductivity than when left unintegrated. This helps to increase heat exchange performance.

Next, a fourth will be described embodiment of the invention. Figure 11 is a plan view of a part of the heat eliminator 4 of this embodiment as observe axially. The heat eliminator 4 of this embodiment, Like the first embodiment described above, it is composed of an element 42 of the heat exchanger, which it comprises an annular corrugated sheet 421 and a member in the form of internal ring 422 brazed within it, and a body 41 into which element 42 of the heat exchanger is mounted hot.

First, the method of manufacture of the annular corrugated sheet 421 used in this realization. Figures 12A to 12C show the procedure of manufacture of the annular corrugated sheet 421. Figure 12A is a plan view of the linear corrugated sheet 420, Figure 12B is an enlarged plan view of the 420 linear corrugated sheet in a rounded state with both ends in close proximity, and the Figure 12C is an enlarged plan view of a part of the annular corrugated sheet 421 in its finished state.

As Figure 12A shows, the sheet Linear corrugated 420 has contiguous grooves 420e, which have a V-shaped section each. At one end of the blade Linear corrugated 420 is a V-shaped groove 420a, and on the other end is a V-shaped groove 420b inverted The outermost side 420c of the groove 420a and the side outermost 420d of slot 420b are formed so that your length L4 is shorter than the length L of the sloping sides between the tips and bottoms 420f and 420f of the slots 420e intermediate.

Linear corrugated sheet 420 is folded in the directions indicated by arrows F1 and F2 in figure 12A to conform to a cylindrical shape, so that the sides outermost 420c and 420d are placed together (figure 12B). Then the surfaces of the outermost sides 420c and 420d, to which a solder in the form of paste is applied in uniform form in advance, they keep in touch with each other and they they heat for a moment so that they weld together. In this way the annular corrugated sheet 421 is manufactured as it is shown in figure 12C. Reference numeral 421g represents the part conventionally welded or electively welded.

As shown in Figures 2A and 11, the member in the form of an inner ring 422 is placed in contact with the inner periphery of the annular corrugated sheet 421, so that Be coaxial with each other. In this case, the diameter of the circle formed by the uniform connection of all funds 421b of the annular corrugated sheet 421 (that is, the internal diameter of the annular corrugated sheet 421) is made to be substantially the same to the outer diameter of the inner ring-shaped member 422.

The corrugated annular sheet 421 and the member in inner ring shape 422 are joined together by a brazing metal 13 in the form of a ring. Specifically, such As Figure 2B shows, the brazing metal 13 is placed where the annular corrugated sheet 421 and the inner ring-shaped member 422, and heating so that molten brazing metal 13 circulates along the bottoms 421b of the annular corrugated sheet 421.

As a result, as shown in the Figure 3, brazing metal 13 is applied substantially evenly in the contacting part of the sheet corrugated ring 421 and the inner ring-shaped member 422. When the brazing metal 13 hardens, the sheet corrugated ring 421 and the inner ring-shaped member 422 is join together and therefore integrate together. Instead of the brazing specifically mentioned above, you can Use conventional welding or similar.

The element 42 of the heat exchanger described above is inserted into a body 41 shown in the Figure 1, so that they are coaxial with each other, thus being manufactured therefore the heat eliminator 4. Element 42 of the heat exchanger is inserted into body 41 by means of the next mechanism. As shown in Figure 4, which is an outline in section of body 41 and element 42 of the heat exchanger, both ends of body 41 are conical, so that the thickness of it becomes smaller towards the ends along its axis (these parts are called as the conical parts 41a).

Additionally, the external diameter of the element 42 of the heat exchanger (i.e. the outer diameter of the annular corrugated sheet 421) R1 (= \ varphiB) is made to be smaller slightly than the maximum internal diameter R2 (= \ varphiB + α1) of body 41 at both ends thereof, and slightly larger than the internal diameter R3 (= \ varphiB - α2 of body 41 in the position thereof between the conical parts 41a.

Thus, when element 42 of the heat exchanger inside the exchanger element of heat 42 from one end thereof, the insertion requires a Small pressure force at the beginning. Since the diameter internal body 41 gradually becomes smaller until eventually it becomes smaller than the external diameter R1 of the element 42 of the heat exchanger, as the element 42 of the heat exchanger, the force required to Doing this operation gradually increases. In this way the element 42 of the heat exchanger can be inserted easily inside the body 41.

In this case, since the bottoms 421b of the annular corrugated sheet 421 are fixed to the inner ring-shaped member 422, the annular corrugated sheet 421 thus mounted on the body 41, in which the internal diameter R3 is smaller than the diameter external R1 of the annular corrugated sheet 421, is brought to a state in which the grooves 421a are pressed so as to be more open, and this produces a radially resilient force towards
outside.

Additionally, since the external diameter R1 of annular corrugated sheet 421 and groove depth 421a are constant along the axis, the resilient force before mentioned press the element 42 of the heat exchanger on the internal surface of the body 41, with a uniform force around in its entirety and therefore keeping it in position. In this case, the annular corrugated sheet 421 and the shaped member of inner ring 422 are fixed together and therefore not being deformed

As described above, in this embodiment, the inner ring-shaped member 422 can set in the desired position within body 41 without the use of Adhesive or welding. This helps to simplify the procedure of manufacturing and reduce manufacturing costs, and also to stabilize the heat exchange performance of the member of the heat exchanger.

Additionally, when the annular corrugated sheet 421 is damaged, element 42 of the heat exchanger can be removed and removed from body 41. This allows for easy replacement as needed, and thus helps mitigate the economic problem to the user in the case of repair and to solve the problems Recycled

Additionally, in element 42 used of the heat exchanger in this embodiment, the corrugated sheet annular 421 and the inner ring-shaped member 422 is they are integrated together by brazing, conventional welding, or similar, and thus showing a better thermal conductivity than when left unintegrated. This helps to increase heat exchange performance.

Next, a fifth will be described embodiment of the invention. Figure 13 is a plan view of a part of the heat eliminator 4 of this embodiment, such as It is observed radially. Heat eliminator 4 of this embodiment, as in the first described embodiment previously, it is composed of an element 42 of the exchanger of heat, comprising an annular corrugated sheet 421 and a inner ring-shaped member 422 brazed inside the same, and a body 41 within which element 42 is mounted of the heat exchanger.

First, the method of manufacture of the annular corrugated sheet 421 used in this realization. Figures 14A to 14C show the procedure of manufacture of annular corrugated sheet 421. Figure 14A is a plan view of the linear corrugated film 420, figure 14B it is an enlarged plan view of the 420 linear corrugated sheet in a rounded state with both ends together together, and Figure 14C is an enlarged plan view of a part of the annular corrugated sheet 421 in its finished state.

As shown in Figure 14C, the sheet Linear corrugated 420 has contiguous grooves 420e that have a V-shaped section on both ends of the corrugated sheet Linear 420 are inverted V-shaped grooves. The side outermost 420e of slot 420a and outermost side 420d of the groove 420b are formed so that its length L5 is more short that the length L of the sloping sides between the tips and the 420f bottoms of the intermediate 420e slots.

Linear corrugated sheet 420 is folded in the directions indicated by arrows F1 and F2 in figure 14A, in order to form a cylindrical profile so that the sides more external 420c and 420d are placed together (figure 14B). Next, the outermost sides 420c and 420d are together with their surfaces in contact with each other on their complete surfaces, are coupled together with a member coupling 18 made of highly resilient material and that have a C-shaped section. This way the laminate is manufactured annular corrugated 421 as shown in Figure 14C.

As shown in Figures 2A and 13, the member in the form of an inner ring 422 is placed in contact with the inner periphery of the annular corrugated sheet 421, so that Be coaxial with each other. In this case, the diameter of the circle formed by the uniform connection of all funds 421b of the annular corrugated sheet 421 (that is, the internal diameter of the annular corrugated sheet 421) is substantially equal to the diameter outer of the inner ring-shaped member 422.

The corrugated annular sheet 421 and the member in inner ring shape 422 are joined together by a brazing metal 13 in the form of a ring. Specifically, such As Figure 2B shows, the brazing metal 13 is placed where the annular corrugated sheet 421 makes contact with each other and the inner ring-shaped member 422, and heating so that molten brazing metal 13 circulates along the bottoms 421b of the annular corrugated sheet 421.

As a result, as shown in the Figure 3, brazing metal 13 is applied substantially evenly in the contacting part of the sheet corrugated ring 421 and the inner ring-shaped member 422. When the brazing metal 13 hardens, the sheet corrugated ring 421 and the inner ring-shaped member 422 is join together and therefore integrate together. Instead of the brazing specifically mentioned above, you can Use conventional welding or similar.

The element 42 of the heat exchanger described above is inserted into a body 41 shown in the Figure 1, so that they are coaxial with each other, thus being manufactured therefore the heat eliminator 4. Element 42 of the heat exchanger is inserted into body 41 by means of the next mechanism. As shown in Figure 4, which is an outline in section of body 41 and element 42 of the heat exchanger, both ends of body 41 are conical, so that the thickness of it becomes smaller towards the ends along its axis (these parts are called as the conical parts 41a).

Additionally, the external diameter of the element 42 of the heat exchanger (i.e. the outer diameter of the annular corrugated sheet 421) R1 (= \ varphiB) is made to be smaller slightly than the maximum internal diameter R2 (= \ varphiB + α1) of body 41 at both ends thereof, and slightly larger than the internal diameter R3 (= \ varphiB - α2 of body 41 in the position thereof between the conical parts 41a.

Thus, when element 42 of the heat exchanger inside the exchanger element of heat 42 from one end thereof, the insertion requires a Small pressure force at the beginning. Since the diameter internal body 41 gradually becomes smaller until eventually it becomes smaller than the external diameter R1 of the element 42 of the heat exchanger, as the element 42 of the heat exchanger, the force required to Doing this operation gradually increases. In this way the element 42 of the heat exchanger can be inserted easily inside the body 41.

In this case, since funds 421b of the annular corrugated sheet 421 are fixed to member 422 in shape of inner ring, the corrugated annular sheet 421 thus mounted on body 41, in which the internal diameter R3 is smaller than the external diameter R1 of the annular corrugated sheet 421, is brought to a state in which the slots 421a are pressed so make them more open, and this produces a resilient force radially out.

Additionally, since the external diameter R1 of annular corrugated sheet 421 and groove depth 421a are constant along the axis, the resilient force before mentioned press the element 42 of the heat exchanger on the internal surface of the body 41, with a uniform force around in its entirety and therefore keeping it in position. In this case, the annular corrugated sheet 421 and the shaped member of inner ring 422 are fixed together and therefore not being deformed

As described above, in this embodiment, the inner ring-shaped member 422 can set in the desired position within body 41 without the use of Adhesive or welding. This helps to simplify the procedure of manufacturing and reduce manufacturing costs, and also to stabilize the heat exchange performance of the member of the heat exchanger.

Additionally, when the annular corrugated sheet 421 is damaged, element 42 of the heat exchanger can be removed and removed from body 41. This allows for easy replacement as needed, and thus helps mitigate the economic problem to the user in the case of repair and to solve the problems Recycled

Additionally, in element 42 used of the heat exchanger in this embodiment, the corrugated sheet annular 421 and the inner ring-shaped member 422 is they are integrated together by brazing, conventional welding, or similar, and thus showing a better thermal conductivity than when left unintegrated. This helps to increase heat exchange performance.

Next, a sixth will be described embodiment of the invention. Figure 15 is a plan view of a part of the heat eliminator 4 of this embodiment, such as It is observed axially. Heat eliminator 4 of this embodiment, like the first described embodiment previously, it is composed of an element 42 of the exchanger of heat, comprising an annular corrugated sheet 421 and a internal ring-shaped member 422 brazed within the same, and a body 41 within which element 42 of the heat exchanger.

First, the method of manufacture of the annular corrugated sheet 421 used in this realization. Figure 16 shows the manufacturing process of the annular corrugated sheet 421. Figure 16A is a view in plant of the linear corrugated sheet 420, Figure 16B is a view in an enlarged plant of the 420 linear corrugated sheet in a state rounded with both ends placed in close proximity, and the Figure 14C is an enlarged plan view of the corrugated sheet cancel 421 in its finished state. Figure 17 is a view in perspective of a main part of figure 16B.

As Figure 16A shows, the sheet linear corrugated 420 has contiguous grooves 420e that has a V-shaped section each. At both ends of the sheet Linear corrugated 420 are the V-shaped slots 420b inverted The outermost side 420c of the groove 420a and the plus side external 420d of slot 420b are formed so that its length L6 is shorter than the length L of the sloping sides between the tips and bottoms 420f and 420f of the intermediate grooves 420e. Additionally, as shown in Figure 17, on the sides more ends 420c and 420d, slots 19 are formed respectively so that a slot extends from a 420g flank of corrugated sheet line 420 in half of the path, and the other slot extends from the other flank 420h of the linear corrugated sheet 420 in the middle of the travel.

The linear corrugated sheet 420 is folded with the directions indicated by arrows F1 and F2 in figure 16A, so that they are profiled in a cylindrical shape, so that the outermost sides 420c and 420d are placed together (figure 16B). TO then the outermost sides 420c and 420d are coupled together by means of the joint coupling with the groove 19 formed on the outermost side 420c and the groove 19 formed on the plus side 420d end In this way the annular corrugated sheet is manufactured 421 as shown in Figure 16C.

As shown in Figures 2A and 15, the member in the form of an inner ring 422 is placed in contact with the inner periphery of the annular corrugated sheet 421, so that Be coaxial with each other. In this case, the diameter of the circle formed by the uniform connection of all funds 421b of the annular corrugated sheet 421 (that is, the internal diameter of the annular corrugated sheet 421) is substantially equal to the diameter outer of the inner ring-shaped member 422.

The corrugated annular sheet 421 and the member in inner ring shape 422 are joined together by a brazing metal 13 in the form of a ring. Specifically, such As Figure 2B shows, the brazing metal 13 is placed where the annular corrugated sheet 421 makes contact with each other and the inner ring-shaped member 422, and heating so that molten brazing metal 13 circulates along the bottoms 421b of the annular corrugated sheet 421.

As a result, as shown in the Figure 3, brazing metal 13 is applied substantially evenly in the contacting part of the sheet corrugated ring 421 and the inner ring-shaped member 422. When the brazing metal 13 hardens, the sheet corrugated ring 421 and the inner ring-shaped member 422 is join together and therefore integrate together. Instead of the brazing specifically mentioned above, you can Use conventional welding or similar.

The element 42 of the heat exchanger described above is inserted into a body 41 shown in the Figure 1, so that they are coaxial with each other, thus being manufactured therefore the heat eliminator 4. Element 42 of the heat exchanger is inserted into body 41 by means of the next mechanism. As shown in Figure 4, which is an outline in section of body 41 and element 42 of the heat exchanger, both ends of body 41 are conical, so that the thickness of it becomes smaller towards the ends along its axis (these parts are called as the conical parts 41a).

Additionally, the external diameter of the element 42 of the heat exchanger (i.e. the outer diameter of the annular corrugated sheet 421) R1 (= \ varphiB) is made to be smaller slightly than the maximum internal diameter R2 (= \ varphiB + α1) of body 41 at both ends thereof, and slightly larger than the internal diameter R3 (= \ varphiB - α2 of body 41 in the position thereof between the conical parts 41a.

Thus, when element 42 of the heat exchanger inside the exchanger element of heat 42 from one end thereof, the insertion requires a Small pressure force at the beginning. Since the diameter internal body 41 gradually becomes smaller until eventually it becomes smaller than the external diameter R1 of the element 42 of the heat exchanger, as the element 42 of the heat exchanger, the force required to Doing this operation gradually increases. In this way the element 42 of the heat exchanger can be inserted easily inside the body 41.

In this case, since funds 421b of the annular corrugated sheet 421 are fixed to member 422 in shape of inner ring, the corrugated annular sheet 421 thus mounted on body 41, in which the internal diameter R3 is smaller than the external diameter R1 of the annular corrugated sheet 421, is brought to a state in which the slots 421a are pressed so make them more open, and this produces a resilient force radially out.

Additionally, since the external diameter R1 of annular corrugated sheet 421 and groove depth 421a are constant along the axis, the resilient force before mentioned press the element 42 of the heat exchanger on the internal surface of the body 41, with a uniform force around in its entirety and therefore keeping it in position. In this case, the annular corrugated sheet 421 and the shaped member of inner ring 422 are fixed together and therefore not being deformed

As described above, in this embodiment, the inner ring-shaped member 422 can set in the desired position within body 41 without the use of Adhesive or welding. This helps to simplify the procedure of manufacturing and reduce manufacturing costs, and also to stabilize the heat exchange performance of the member of the heat exchanger.

Additionally, when the annular corrugated sheet 421 is damaged, element 42 of the heat exchanger can be removed and removed from body 41. This allows for easy replacement as needed, and thus helps mitigate the economic problem to the user in the case of repair and to solve the problems Recycled

Additionally, in element 42 used of the heat exchanger in this embodiment, the corrugated sheet annular 421 and the inner ring-shaped member 422 is they are integrated together by brazing, conventional welding, or similar, and thus showing a better thermal conductivity than when left unintegrated. This helps to increase heat exchange performance.

A seventh will be described below. embodiment of the invention. Figure 18 is a plan view of heat eliminator 4 of this embodiment, as noted axially Heat eliminator 4 of this embodiment, like that the first embodiment described above is composed by an element 42 of the heat exchanger, comprising a annular corrugated sheet 421 and a ring-shaped member inside 422 brazed inside it, and a body 41 inside of which element 42 of the heat exchanger is mounted hot.

First, the method of manufacture of the annular corrugated sheet 421 used in this realization. Figures 19A and 19C show the procedure of manufacture of the annular corrugated sheet 421. Figure 19A is a plan view of the linear corrugated sheet 420, Figure 19B is a plan view of the annular corrugated sheet formed by the rounding of the linear corrugated sheet and placing both ends thereof together, and figure 19C is a top view of the cylindrical body 41.

As Figure 19A shows, the sheet Linear corrugated 420 has contiguous grooves 420e that have a V-shaped section each. At both ends of the sheet Linear corrugated 420 are the V-shaped slots 420b inverted The most extreme side 420c of the groove 420a and the most side end 420d of slot 420b are formed so that their length L7 is shorter than the length L of the sloping sides between the tips and bottoms 420f and 420f of the slots 4202 intermediate.

Linear corrugated sheet 420 is folded in the directions indicated by arrows F1 and F2 in figure 19A, in order to conform to a cylindrical profile, so that the more extreme sides 420c and 420d are placed together. TO then the linear corrugated sheet 420 is held in a state in which the most extreme sides 420c and 420d remain in contact with each other at least at their tips. This way it is manufactured annular corrugated sheet 421 as shown in the figure 19B. As a result, the parts of the tips of the sides more ends 420c and 420d form a projecting part 421h than protrudes radially outside the outer periphery of the sheet annular corrugated 421 (that is, the circle formed by the connection uniform of all tips 421c).

The internal diameter of the cylindrical body 41 is made substantially equal to the outer diameter of the sheet corrugated ring 421. Additionally, as shown in the Figure 19C, in a position of the internal surface of the body 41, a groove 41a is formed into which the part fits projection 421h of the annular corrugated sheet 421 in order to extend axially.

The annular corrugated sheet 421 is inserted then axially in body 41 with the center of the first aligned with the central axis of the last one, with the protruding part 421h of the first embedded in slot 41a of the last. In this case, as indicated in Figure 1, the annular corrugated sheet 421 is inserted until one end of it becomes flush with the open end of the body 41.

On the protruding part 421h of the corrugated sheet annular 421 acts a force that tends to carry the corrugated sheet cancel 421 return to the original state of the corrugated sheet linear 420. However, since the projecting part 421h remains trapped in groove 41a, the force becomes a force that tends to expand the annular corrugated sheet 421 radially. Thus, the annular corrugated sheet 421 expands radially, and therefore presses on the internal surface of the body 41. This makes it possible to keep the annular corrugated sheet 421 in position desired while maintaining its shape.

On the contrary, the outer diameter of the member in the form of an inner ring 422 is made substantially equal to internal diameter of the annular corrugated sheet 421 (i.e. diameter of the circle formed by the uniform connection of all 2b funds). The inner ring-shaped member 422 is inserted axially in the annular corrugated sheet 421 with the center of the first aligned with the central axis of the last. TO then the annular corrugated sheet 421 and the shaped member of inner ring 422 are integrated together by joint brazing where the inner periphery of the first makes contact with the outer surface of member 422 in internal ring shape. In this way, element 42 of the heat exchanger is mounted on body 41, and therefore heat eliminator 4 is obtained as shown in the figure 18.

Thus, it is possible to eliminate the joining process or welding the annular corrugated sheet 421 to the body 41. This It improves productivity. Additionally, it is possible to set with security the annular corrugated sheet 421 by mounting to pressure, and get uniform contact in all parts around annular corrugated sheet 421. This helps to manufacture the heat eliminator 4 stably with performance Excellent.

Next, an octave will be described. realization. Figure 20 is an external perspective view of the heat eliminator 4 serving as a member of the exchanger of heat in this embodiment. Figure 21A is a view in external perspective and an exploded perspective view, respectively, of element 42 'of the heat exchanger Built-in heat eliminator 4.

This element 42 'of the heat exchanger It is composed of an annular corrugated sheet 421 and a member in 422 'outer ring shape. The corrugated annular sheet 421 is manufactured by the same procedure as previously stated in relationship with the first to the seventh realizations. The member in outer ring shape 422 'is a cylindrical member of a material that has thermal conductivity and resilience excellent.

As shown in Figure 21A, the member in the form of an outer ring 422 'is located in contact with the outer periphery of the annular corrugated sheet 421, so that Be coaxial with each other. In this case, the external diameter of the annular corrugated sheet 421 is made substantially equal to inner diameter of the outer ring-shaped member 422 '. Additionally, as shown in Figure 22, the sheet annular corrugated 421 and the outer ring-shaped member 422 ', like the annular corrugated sheet 421 and the shaped member of inner ring 422 of the first embodiment, are joined and fixed together with a brazing metal 13 or welding conventional.

The element 42 'of the heat exchanger described above is inserted in a body 41 shown in Figure 20, so that they are coaxial with each other, and therefore thus producing the heat eliminator 4. Element 42 'of the heat exchanger is inserted into body 41 by means of the next mechanism. As shown in Figure 23, which is a sectional outline of body 41 and element 42 'of the exchanger of heat, both ends of the body 41 are conical of the same so that in the first embodiment (these parts are called as the conical parts 41a).

Additionally, the external diameter of the element 42 'of the heat exchanger (i.e. the outer diameter of the member 422 'outer ring-shaped) R1' (= \ varphiB ') is slightly smaller than the maximum internal diameter R2 ' (= \ varphiB '+ \ alpha_ {1}') of body 41 at both ends of the same, and slightly larger than the internal diameter R3 ' (= \ varphiB '- \ alpha_ {2}') of body 41 in the part of the same located between the conical parts 41a.

So, as in the first embodiment described above, conical parts 41a allow the element 42 'of the heat exchanger is inserted into the body 41 more easily. Additionally, element 42 'of heat exchanger mounted thus in the body 41 is pressed on the internal surface of the body 41, and thus staying in position through the flexibility that takes place in the sheet annular corrugated 421 and the outer ring-shaped member 422 '. In this case, the annular corrugated sheet 421 and the shaped member of outer ring 422 'are firmly fixed together, and therefore not deforming.

As described above, and in this embodiment also, the element 42 'of the heat exchanger it can be fixed in the desired position within the body 41 without the use of any adhesive or solder. Additionally, since the element 42 'of the heat exchanger and the body 41 are not set together, the first can be extracted from the last in Free form. Additionally, since the corrugated sheet 421 annular and outer ring-shaped member 422 'are integrated together, show better conductivity thermal

Next, a novena will be described embodiment of the invention, with reference to the drawings. The Figure 24 is an enlarged plan view of a part of the heat eliminator 4 of the embodiment, as noted axially Figure 25 shows part of the procedure of manufacture of heat eliminator 4; specifically, the figures 25A and 25B are respectively section views of the eliminator of heat before and after element 42 of the heat exchanger, and that is inserted from the side of the guide member thereof.

As Figures 25A and 25B show, a cylindrical body 41 is fixed with a guide member 14, to a template 15, with the shaft of the body 41 maintained substantially horizontally The guide member 14 is provided for the purpose coming into contact with body 41, and has an external diameter substantially equal to that of body 41. Guide member 14 is formed so that it has a conical cross section inside, forming a conical part 41a, so that its internal diameter is equal to the internal diameter of the body 41 in the joint e increasing as you move away from it.

Next, the procedure of manufacture of heat eliminator 4 of this embodiment, with reference to figures 25A and 25B. Corrugated ring 421 It is manufactured in the same way as described above in relationship with the first to the sixth realizations, that is, by forming a linear corrugated sheet 420 in a cylindrical shape and placing both ends together. The 421 annular corrugated sheet is made of a highly material flexible that easily deforms when applying a pressure force external

In advance, the ring-shaped member internal 422, in which the external diameter is made slightly greater than the outer diameter of the annular corrugated sheet 421, is has inserted axially into annular corrugated sheet 421, in order to manufacture the element 42 of the heat exchanger. TO then, as shown in Figure 25A, element 42 of the heat exchanger is inserted axially into the member of guide 14 from the open end thereof. So, the lamina annular corrugated 421 is gradually pressed through the part conical 14a of body 41, that is, from the part thereof that have a larger internal diameter to the part of it that has a smaller internal diameter

Next, as shown in Figure 25B, the insertion stops when an extreme surface of the sheet corrugated ring 4221 becomes flush with the gasket between the body 41 and guide member 14. Meanwhile, tips 421c of the 4221 annular corrugated sheet rub against the surface internal of the guide member 14, and therefore deforming from the Arc shape to flat shape. The degree of this deformation is in proportion to the amount of material of the guide member 14 that is harder than the material of the annular corrugated sheet 421. As Figure 24 is shown, this increases the area of contact between annular corrugated sheet 421 and the surface inside the body 41. This helps improve efficiency with the which heat is transmitted from the annular corrugated sheet 421 towards body 41, and thereby improving the performance of the heat exchange of heat eliminator 4.

Next, a tenth will be described realization with reference to the drawings. Figure 26 is a view in plan of the heat eliminator 42 of this embodiment, the figure 27 is a plan view of element 42 of the heat exchanger heat, and figure 28 is a plan view of the body cylindrical.

Around the outer periphery of a sheet annular corrugated 421 ', the projections are formed in the form of a wave round profile 421 k, so that they are in intimate contact between Yes and at regular intervals. On the contrary, body 41 is manufactures by pouring molten metal into a mold and cooling it. As shown in Figure 28, body 41 has 41m waveform slits formed at regular intervals all around its inner surface in order to spread axially These slits 41m have a shape so that the 421k waveform projections mentioned above of the sheet annular corrugated 421 'fit into it.

As shown in Figure 2A, the member in the form of an inner ring 422, in which the outer diameter it is made slightly substantially in the same way as internal diameter of the annular corrugated sheet 421 ', the 421 'annular corrugated sheet, and being jointly brazed where they make contact with each other, in order to manufacture the element 42 of the heat exchanger in Figure 27. Next, such as shown in figure 4, the element 42 of the heat exchanger heat is inserted axially inside the body 41, with the center of the first aligned with the central axis of the last. In this case, such as shown in figure 26, the projections 421k of the sheet corrugated ring 421 'fit inside the grooves 41m of the body 41. This will ensure that in heat eliminator 4, the element 42 of the heat exchanger 42 remains fixed in safely in a circumferential position within the body 41. Thus, in this embodiment, it is possible to maintain the sheet corrugated ring 421 'in firm and intimate contact with the inner surface of the body 41, and thus fixing an area large enough contact all around the sheet annular corrugated 421 '. This helps make the heat eliminator 4 stably with excellent performance.
