Description

[Detailed Description of the Invention] The present invention relates to the structure of a heat exchange fin portion in a heat exchange device, and the heat transfer coefficient is greatly increased by widening the heat exchange area of the fin structure. It is about new structures that increase

Conventionally, is it possible to use individual fins as a means of expanding the heat dissipation area of the fin section? Fin pitch for large area? How many fins should I make smaller? Increasing the thickness of each fin to prevent a pressure drop in the heat exchange fluid and reducing the fin pitch; it depends on the unevenness of each fin to completely expand the surface γ1 and to reduce turbulent flow. The usual method was to increase the fin efficiency by increasing the total amount of heat generated.

However, if the total volume of the fin part is limited, the surface M of each fin
It may be impossible to increase k. Furthermore, reducing the pitch of the fins also increases the fluid resistance of the heat exchange fluid, which may actually reduce the fin efficiency. Increasing the thickness of each fin also prevents an increase in fluid resistance, which also reduces the mechanical strength of the fins and makes the fin gap unstable.
However, it tends to increase fluid resistance and has a limitation. Although providing unevenness on the fin surface is an effective means, it increases the cost of the fin and is often impractical.

The present invention solves these problems, easily expands the heat exchange area even when there is a limit to the fin groove, and also compensates for the mechanical strength even if the fin wall thickness is reduced. A new structure that creates turbulent noise in the flow of heat exchange fluid to improve fin efficiency? This is what we intend to provide. In addition, the novel fin structure provided by the present invention makes it easy to connect all the auxiliary fins to each fin to expand the heat exchange area if there is enough space for the fin. A heating element on the formed plane? It is possible to bond the part and configure it as a heat absorbing part that extremely efficiently sends and radiates heat into the whole fin part, which is considered to be virtually impossible with conventional fin structures. It also provides many valuable effects such as realizing all the things that were previously planned.

FIG. 1 shows a side view of the fin part of a group of flat fins manufactured by Jyubei Seizo. 20 is a heating element, and 21 is a flat fin group. In the case of such a fin group, when the length of one side of the fin becomes about 300 mm, it becomes extremely difficult to form a large fin density. Fin pitch 2rr
ab When the fin thickness is about 0°4, the sizing efficiency decreases due to the fin deformation, and the sizing gap becomes unstable. Sometimes it was lost.

2, 3, and 4 are sectional views showing the basic structure of the heat exchange fin portion according to the present invention, respectively. l is a fin support. In normal cases, l is a heat radiator or heat absorber that requires heat exchange. The heat absorbing and dissipating body may be a wall surface, a cylinder, a prism, etc., or an outer peripheral wall surface of a hollow tube through which a high temperature fluid or a low temperature fluid flows. Furthermore, even the outer peripheral wall of the heat pipe container is affected.
It may also be a so-called permanent wall surface of a heat sink.

Further, l is a fin support body for fixing the fin pitch of the heat exchange fin group and holding the structure of the fin portion. In such a case, the heat absorbing/radiating body is used by being in contact with a predetermined portion of the fin portion.

2 is a main fin, which is a flat fin or an annular fin. The main fins 2 may be formed integrally with the fin support 1 as shown in the figure, or may be formed with holes formed separately and completely press-fitted, or may be soldered, brazed, or welded.
It doesn't matter if it is connected by any means. Alternatively, it may be a so-called loaf-in with a thick wall and a low height (it may be extremely thin with a thickness of 0.4 m or less).Furthermore, it may be a bellows fin of a bellows type heat pipe.

The three-piece spring structure is constructed by forming a thin metal wire of a predetermined diameter with good thermal conductivity into a spiral shape with a predetermined helical diameter and a predetermined helical pitch. The diameter of the metal front 11 wire is 0
．． In the case of an ultra-thin wire of 0.05 mm, it may be a medium-thin wire with a diameter of 1 mm, and it is determined depending on the size of the gap between the fins to be installed, the type of heat exchange fluid, the flow rate, and the usage condition of the fin section. Ru. The helical diameter and helical pitch are also determined in the same manner. The spring structure is elastically clamped between each opposing fin plane as shown. The various states of the clamping of the spring structure are shown in the nine representative sidetone figures. In FIG. 2, the center line of the spiral of the spring structure is arranged parallel to the height direction of the fin, that is, perpendicular to the plane of the fin support. In Figure 3, the center line of the spiral is arranged perpendicular to the plane of the opposing fin, i.e. parallel to the plane of the fin support.
In FIG. 4, the center line of the spiral is parallel to the fin plane and parallel to the fin support surface.

Although not shown in the drawings, when the fin support is cylindrical or cylindrical in FIG. Arranged in series between the same sides regardless of the shape of the support
There are cases. Similarly, although not shown in the drawings, when the fin support is columnar or cylindrical, the spring structures are arranged concentrically along the outer peripheral plane of the fin support;
The fins may be arranged in a spiral manner, or may be arranged in a rectangular manner, regardless of the shape of the fin support.

It is a common essential condition of the fin part structure according to the present invention that the opposing fin planes are thermally connected via the spring structure having countless pressurizing contact points in any number of arrangement states. I am a connoisseur. The spring structure may be provided with mild elasticity or strong elasticity depending on the purpose of use of the 147-part structure required, and may be provided with 7 nV.
The helical diameter, helical pitch, metal material used, and heat treatment condition are determined as a ratio.

Since the structure of the heat exchanger fin portion according to the invention has the basic structure as described above, it basically exhibits the following functions and effects.

1) Greatly improve the heat exchange performance of the fin group.

Since the spring structure is in pressure contact with the fin plane and is thermally connected, the fin surface area is substantially increased by the surface area of the thin wire of the spring structure, thereby increasing the heat exchange area.

1 mouth) The thermal resistance of each fin is different from the case where the fin surface value is expanded C and the fin taste r is increased as the total distance ba from the heat radiator or heat absorbing hexagonal surface is not increased. The same effect can be achieved as reducing the amount of fins, and the overall fin effect can be improved.

No. 1 The expansion of the fin area described above is due to the fact that the tin ring structure is formed of thin wires and has a uniform ratio of 9 nitrogen, so when the total number of fins is increased, it becomes softer and has less resistance to the flow of the heat exchange fluid, resulting in less pressure loss. Less is.

) The generation of turbulence in the heat transfer body by the spring structure increases the heat transfer coefficient of the fin plane and increases the fin efficiency.

Since the spring structure generates a turbulent flow in the heat exchange fluid, not only is it difficult for the fins to become clogged with dirt, etc., but if the fins become clogged, it can be easily cleaned. This is a miserable but useful effect as a heat exchange fin.

(F) The fin thickness is extremely thin and the area can be increased. If the thickness of the fins is made seventeen thinner, the strength of the fins decreases, and it becomes difficult to maintain the fin gap at a constant distance due to the anti-9-v' deformation, making it difficult to increase the fin area. The spring structure has fins r depending on its elasticity.
It is possible to support and keep the gap constant.

Therefore, it is possible to form the fins thinly and widely. The spring structure has a fine wire diameter to. Since it is easy to form a helical diameter of 0.05 mm or less and a helical diameter of 11 mm or less, it is also possible to form thin-walled fins in any desired fin area with a total pitch of 1 mm or less, such as in the order of 0 and 2, which was previously impossible. .

(g) Strength of the fin part? It can be greatly strengthened. Since each fin is elastically supported by the spring structure, the strength of the entire fin group is increased, and it is also protected against external interference. The fin structure also has extremely strong strength.

Depending on the combination with the twin structure, the heat radiation area can be expanded by connecting all the auxiliary fins as described below, and it is possible to attach all the IU heat radiation elements and heat absorbers to the edge of the fin, which was previously impossible. The possible deflections have little or no negative effect on the heat exchange performance of the main fins.

Since the heat exchange fin portion according to the present invention has the basic structure and basic functions and effects as described above, what is the structure and function of the fins, etc.? Depending on the appropriate combination, a number of practical heat exchange fin structures can be provided.

5 and 6 show an application of the heat exchange fin structure according to the invention to a fin section having a group of flat fins. 5 is a perspective view of a heat exchange fin section that relies on forced convection, and FIG. 6 is a heat exchange fin section that relies on natural convection. Indicates the direction of the flow.No matter what number n is 2 in the figure, l is the fin support and 6D is the heat sink or heat absorber.-i! A large number of spring structure trees 3 are elastically clamped under pressure.The chain names in both figures indicate the perpendicular direction of the center line of the spiral of the spring structure.

In FIGS. 5 and 6, the center lines are arranged parallel to each other in a direction perpendicular to the direction of the fluid flow hole. The arrangement of such a spring structure has the least resistance to the fluid and the least pressure loss, so heat exchange by forced convection is possible:
Since the fin pitch is small, it is effective when used in a group of dense fins, and the spring structure has low resistance to natural convection heat exchange as shown in Fig. 6 because the fluid flow velocity is low. Arrays are preferred.

≠ in Figure 2 indicates that the head of the tightening bolt for pressure clamping is unique. In the case of such a tin ring structure arrangement, strong turbulence is generated by the jet of fluid flowing in the direction of the center line of the spiral, and foreign matter such as dust stagnant in the fin structure is easily removed (C division method). There are 10 points that can be done.If dirt builds up in the fin structure after long-term use, the spring structure can be removed very easily by loosening the pressure tightening bolt μ. A great advantage of unstructured materials is that they can be used to

In Figure 6! The 6-station plate, which is a side plate and can be freely layered by means not shown, not only contacts the edges of the fin group and expands the heat dissipation area, but also serves as a smoke plate along with the outermost fins at both ends. By forming a structure r, and depending on its chimney effect, the flow rate of the natural vs. bl of the heat exchange fluid is increased.
As a tin ring structure used for the fin part as shown in FIGS. 5 and 6, the diameter of the gold cormorant wire is 0.1 mm, and the helical pitch is 0.1 mm.
3 rrun spiral diameter 2rraK forming opposing fin plane length - gi 30° group, length of tin ring structure 300
If m, the spring structure 1 irregularity 9 surface ridge is 2
Therefore, if the fin surface area is 180 x 10-3 square meters on both opposing planes, the area of the 45 spring structure trays held in the gap between the two planes is 90 x 10. -3 square meters and heat exchange m
”Hen will increase by 50%. If the fin pitch is large for this heat exchange rate of increase, the fin plane will decrease, and conversely, the coating area of the spring structure will increase as the thin metal wire diameter and spiral diameter increase. . In other words, the rate of increase in surface area due to the infertile fin spring structure of the fin pattern is large.

FIG. 7 is a perspective view showing another applied example of the structure of the heat exchange fin portion according to the present invention. In this case, the application is to a group of annular fins, and l is a heat radiator or a heat absorber which is a fin support. -2 is an annular fin which is the main fin, 3
is a spring structure. The chain line indicates the arrangement of the two tin ring structures in the gap between the opposing fin planes? In the illustrated embodiment, the fin supports are arranged in a spiral manner with the entire center at the center. As for the arrangement of the spring supports, regardless of the fin shape, the method of arranging them in parallel perpendicularly to the n-direction of the heat exchange fluid flow is shown in Figures 5 and 6. In the non-embodiment 1, all of the elongated spring structures are used and arranged in a spiral configuration, although possible advantages are considered. The four points in this embodiment involve only the surface winding work of the spring structure. Also, the flow of heat exchange fluid during use
It also has the advantage of being able to be used without considering directionality. Also, the IC in the direction facing the front and the opposite side with respect to the fin support which is provided with a resistor against the flow of the heat exchange fluid.
j? In addition, the spring structure has a structure with low resistance and a large resistance against other flow n directions, and more turbulence occurs on the side where J-flow is likely to occur, so the overall flow of the fluid is reduced. It also has the advantage of making it more uniform and improving fin efficiency. In the figure, Hiroshi is attached with a special head of a decorative bolt for clamping the spring structure under pressure.

The main purpose of the structure of the heat exchange fin portion according to the present invention as described above is to increase the heat exchange area, and for this purpose, it is necessary to clamp the spring structure in a relatively dense thigh. If a large number of spring structures are pressurized and clamped with high precision, the processing cost for inserting and clamping the n etc. will increase, which may increase the cost of the fin structure.

Further, although the spring structure has a small fluid resistance, a large number of parallel clamps causes a decrease in the pressure of the heat exchange fluid due to the increased resistance. In addition, as mentioned above, when the spring structure is densely arranged with a fin pitch of 2ran or less, the diameter of the thin metal wire becomes extremely thin, and the spiral diameter also becomes extremely small, so that the rate of increase in the heat exchange area becomes small. This will reduce the effectiveness of the fin structure. In such a case, the main purpose of the uninvented fin structure is to increase the heat exchange area, and is it effective as a spacer to maintain the spacing between the fins? By using it as the main purpose, it becomes possible to delay the purpose. In other words, if you wish to double the heat or heat exchange area of a fin group of 300 m x 300 m with a fin wall thickness sail of 4y++ms and a fin pitch of 2rtan, then according to the above calculation example, n will require 90 spring structures. It is easily possible to double the heat exchange area by setting the numbness to 0.15 to 0.2 and the fin pitch to 8 to 1. In the case of a fin group with a conventional structure, it is impossible due to manufacturing technology to form 9 fin groups on 300 RAN x 300 mm fins with such a narrow fin pitch of 1, and the fin gaps will become unbalanced. On the contrary, it increased fluid resistance and was ineffective. However, as another effect of the spring structure according to the invention, it is possible to reliably form a fin group with a single fin pitch by pressing and holding the minimum required number of spring structures as spacers for each fin. It becomes possible to reach.

In such a case, the spring structure is made by using thin metal wires of 0.04 to 0.05 tranO, formed into a spiral diameter of 0.8 to 1.2, and clamped under pressure as a spacer. The purpose is to make it below 10? You can make it happen. In this case as well, the spring structure naturally contributes to the expansion of the heat exchange m1, and the structure of the fin portion according to the invention ultimately makes a large contribution to the wide expansion of the heat exchange area as a whole. become.

The structure of the heat exchange fin part according to the present invention does not utilize the thorn area of the sgelling structure itself to expand the heat exchange plane, but rather increases the number of fins in the fin group. ! As mentioned above, it has the effect of increasing the number of fins, but it is also extremely effective in connecting it to the auxiliary fin and expanding it to a larger width as a heat exchanger. Fig. 8 shows the conventional auxiliary fin. 9 to 14 are cross-sectional views showing various states in which auxiliary fins are connected by applying the fin structure according to the invention, and 2 in each figure shows the fins. The pitch is enlarged and shown. / is the fin support, 2 is the king fin, and 6
The green fin holder may be a flat surface, or may be a circular cylindrical or cylindrical outer peripheral wall surface. Therefore, the raw fin-2 may be a flat fin, a circular fin, or a circular fin. 6 and 7 are auxiliary fins connected to the main fins to expand the heat exchanger. In the conventional method shown in FIG. 8, the auxiliary fins were usually connected to the main fins by attaching half-EH holes or press-fitting metal pieces. ♂ in the figure is the solder alloy,
Or put down 7 pieces of metal. The solder layer interposed between the main fin fin and the auxiliary fin 6 is omitted from the drawing.

Also, a thermally conductive bonding material may be used instead of a solder bonding layer. In the case of soldering, hold the metal piece 2 under pressure while soldering, or inject enough solder and let it cool and solidify.
A drawback of the conventional connection structure is that the main fin, which is the largest in number, loses its heat dissipation properties as a fin. Also, in the drawing, the work of contacting the two fins, which may seem easy at first glance, is done on the inner axis when the fin pitch is small. In addition, when the auxiliary fins are thin, it is difficult and almost impossible to partially extend the fins so as to keep the distance between the fins Ji4J at 9r foot distance.

[Regarding the present invention illustrated in FIGS. 9 to 14] Is the connection structure of the auxiliary fin to which the entire fin structure is applied the conventional connection structure as illustrated in FIG. 8? This improves the connection process and makes it extremely easy to connect the auxiliary fins, without reducing the fin efficiency of the main fins, increasing the raw fin rate, and ensuring the connection of the auxiliary fins. It's a structure.In each figure, υ is 3-/
is a spring structure, and due to its l1llll nature, the spring structure itself is pressurized and clamped by the IMJ of the main fin, and one end of the auxiliary fin inserted between the main fin is held flat by the main fin. Apply pressure and clamp. Therefore, the king fin, auxiliary fin and sgelling structure 3-/
The three parts are thermally connected to each other.

However, since the contact area is large, the thermal connection is reliable even though welding is not involved. Each figure shows each type of clamping method for the spring structure 3-/. 9 and 10, the center line of the spiral of the spring structure 3-/ is placed on the surface of the fin support and is held in parallel in the height direction of the main fin. Therefore, if the fin support l is flat, the spring structure #
are arranged in parallel n, and if the fin support is cylindrical and necessarily/8, they are arranged radially T'L. Compared to other examples, this method is characterized by the point at which the auxiliary fins are removed and removed once they are inserted. In FIGS. 11 and 12, the center line of the spring structure is arranged parallel to the surface of the fin support l and perpendicular to the direction of the island of the fin. Therefore, if the surface of the fin support is flat, the spring support groups with the same inter-fin gap are arranged in parallel, and if the surface of the fin support is a circumferential plane, they are arranged in concentric circles or rj throughout the entire fin support. ) and are arranged in a spiral shape. The advantage of this method is that the spring support body can be easily removed gradually, and when the auxiliary fins become frozen, it is easy to disassemble and clean them.

In FIGS. 13 and 14, the centerline of the spring structure is perpendicular to the planes of the opposing fins and parallel to the planes of the fin support and carrier. If the fin pitch is large, can this method be used as a spring structure with a large spring constant? Auxiliary fins 84 = Used to strongly hold the tray. Each figure vcj? Figures 9, 11 and 13
The figure shows a structure in which the auxiliary fins are pressurized and held on both sides of the main fin, and this method is implemented when the spring constant of the spring structure is relatively small and the auxiliary fins are strong.
The spring structure is formed by holding the spring structure in advance on the auxiliary fin curve and inserting it into the main fin gap all at once. In this method, it is difficult to insert the entire spring structure after inserting all the auxiliary fins between the fins.

Figures 10, 12, and 14 collectively show a structure in which the main fin is clamped under pressure on one side of the plane, and the clamping irL
An appropriate number of auxiliary fins per plane is 91 to 3 auxiliary fins. This method is constructed by first pushing in the auxiliary fins and then press-fitting the spring structure to connect the auxiliary fins from the end of the fin group. With this method, regardless of the strength of the auxiliary fins, a strong fin connection structure can be constructed using the spring constant Kina spring structure tray.

Since the fin connection structure according to the present invention is as described above, it has the following characteristics.

(B) Connection work is extremely easy.

tron The main fin gap allows for free flow of heat exchange fluid even after the auxiliary fins are connected. Therefore, the heat exchange area of the fins does not decrease, and the heat exchange area of the fins does not decrease. SuiO V9 The connection structure can be disassembled and reassembled freely, making maintenance easy, and it is also easy to respond to design changes and clean the clogging 9.

) Regarding the auxiliary fins, the fin capacity can be expanded to a large width by holding the stripes 9 and 4--2, and the fin gap tray can be held in a good condition. Body 3-. 2 is not an essential requirement for the connection structure according to the present invention.

Since FIGS. 8 to 14 have described the structure in which the soil-containing fins are directly connected to the auxiliary fins, the structure of the fin portion according to the present invention can also be provided with other fin connection structures. Figure 15 is a sectional view showing the connection structure.
). In the figure, 2 indicates a cylindrical or cylindrical fin support. The fin support generally serves as a heat sink or heat sink. λ is the main fin and is an annular fin. 6 is a phase for expanding the heat dissipation surface (auxiliary fins). 3-/ is a spring structure for disconnection &m. 3-2.3-J is a heat dissipation surface 4j' (
Even if it is a spring structure for private use, it is not essential as a connection structure related to the invention. 3-1 degree, 3-7 is 3-. 2 and j
-j [In comparison, a large spring constant is given to the light component, and it is necessary to strongly pressurize the VC near the edge of the king fin.

Also, the protruding part on the edge of j-/ coincides with the circumferential plane formed by the edge of the fin path deformed by pressure.
:) It smells like being out on the street. In the drawing, the auxiliary fin 6 is formed by a press-fit iron layer on the cylindrical outer circumference formed by the main fin edge and the protrusion of the spring structure.Therefore, the auxiliary fin is attached to the main fin circumference. The spring body is attached to the top of the spring structure and the spring body is attached to the circumference of the spring structure by pressing the iron layer into the fin edge and the circumferential plane r-shape Jj)t. ,are doing. Although it is not clearly shown in the diagram, the valley auxiliary fin is punched with a hole equal to the outer circumference of the king fin.
1. There is a burring process n'''C. In Figure 2, depending on the elasticity of this burring process part, there is an iron layer n'' elastically press-fitted to the outer circumferential surface of the fin and the outer circumferential surface of the spring structure. The spring structure 3-3, which is sandwiched between the fin planes, is sandwiched for the purpose of maintaining the heat exchange plane and the fin gap, but in the case of an unstructured structure, the burring of the auxiliary fins The effect is to prevent the parts from moving and strengthen the connection structure.

The uninvented connection structure between the king fin and the auxiliary fin as illustrated in FIG. 15 has the following features.

Similar to the conventional technology, the auxiliary fins are installed by crawling by press-fitting (n6°) Even after the auxiliary fins are installed, the heat exchange fluid can freely flow in the main fin exit J gap, and the fins of the main fin group Rather, the heat transfer amount of the main fin portion increases due to the surface area of the sgelling structure for disintegration without reducing efficiency.

I/i The connected structure shown in Figures 9 to 14 has the advantage of being able to be disassembled and reassembled freely, whereas the unconnected structure cannot be disassembled and reassembled as with the conventional Shinjo Fin Confucian. ◇.

The fin connection #A structure of the heat-protection fin portion according to the present invention is not limited to a flat fin or an annular fin as an auxiliary fin. In other words, the spring structure itself may be constructed as a metal fin or a round fin, and FIG. 16 is a sectional view showing an embodiment of such a ratio 1. The 16th fin support has a cylindrical shape, and the p1 king fin-2 has a loam-like fin. Sj-/ is a spring structure that also serves as an auxiliary fin. A part of 3-/ is elastically clamped around the outer periphery of the main fin at a position close to the edge of the main fin, and the remaining part of BD is exposed from the outer edge of the main fin. Auxiliary fins? It consists of The spring structure for the auxiliary fin is wound around the edge of each opposing fin plane of the main fin,
Although the end wood trays may be connected to each other by soldering, brazing, or substantially welding, it is extremely important to use an annular spring structure formed in a donut shape in advance as shown in FIG. 17. It can be used as a wave layer in between. 3--2 is simply a spring structure for expanding the thermal father area, and is not an essential structure for the nine-force flow example. Spring structure 3- in such a case. 2 can also be formed very easily by press-fitting and using the annular spring structure illustrated in FIG. A simple auxiliary fin connection structure such as the one in this example is useful when designing a thermal design, such as when using a circuit board with a large number of heat exchanger fins layered in a wave layer or a heat distribution system within a device housing. extremely useful.

In the present invention, the heat exchanger fin structure is made up of inexpensive structural elements, and the sonic shaft material used is a wide range of wires ranging from ultra-fine wires with a diameter of 0°031rrIn to wires with a diameter of 0.03mm. You can use all of the ranges and make use of them depending on their usage and fin structure.

In addition, the material for the metal frame material ranges from soft materials such as aluminum and pure copper to strong materials such as copper-coated steel wire and steel wire.
A wide range of gold nugget materials can be used depending on the thickness of each fin, the core thickness and the size of the pressure clamping force (2"L/). Also, the spring can be made of only a single wire. In the case of a spring structure formed entirely of a single wire and formed into an ellipse with a very small helical pitch, there is a drawback that buckling is likely to occur due to pressure applied from a direction perpendicular to the center line. In such cases, the entire spring structure can be constructed so that buckling does not occur due to inertial pressure by using several metal wires and forming the helical pitch with a small spacing and a large helical pitch. I can do it.

Figure 18 shows a spring J constructed using multiple thin metal wires.
This is an example of the entire PI structure. Formation of each single wire j′-The paper part of the curve is enlarged fL, and the recession part of the curve is also gentle. The structure 7 may be formed into a two-round screw having a fixed helical diameter and a predetermined helical pitch.

According to the structure of the heat exchanger fin portion according to the present invention, when mounting the sgelling structure, low melting point gold ingots are preliminarily applied to the opposing fin plane, the (μ) of the spring structure, or both.
After the coating is completed, heat the entire plate at once by applying a method such as applying no plating powder, etc., so that the sedge ring structure and the fin plane are brought into contact with each other at the dust fence. is completed. Also, by metal plating the entire structure after completing the iron layer, it is possible to connect the two parts at their contact areas. Further, a shielding material having good thermal conductivity may be attached to the pre-attached portion of the counterfeit 4. Is the heat exchange performance of the structure in which the uninvented fin part is constructed with a dust shield by means of each building? It can be further improved.

However, in this case, it is necessary to sacrifice some of the laminar flexibility of the spring structure of the heat exchange fin portion according to the present invention.

In the structure of the heat exchange fin part according to the present invention, even if the basic structure is fully applied, the heat exchange area is insufficient7)
In this case, the spring structure according to the present invention can be wound around the outer periphery of the sound fin to expand the heat exchange area. Figure 20 shows the situation. Fin support/vcIf: Spring structure 3. -/, 3--2 are clamped and the heat exchange direction of the fins λ is expanded. Further, a large amount of spring structure 3-3 is wound around the outer periphery of the spring structure. The additional spring structure is spring structure j-/or j-
If / does not protrude, it touches the outer periphery of the fin group and heats up at the contact area. The heat absorbed and dissipated, or the heat of the heat exchange fluid? Absorb and PA to j-/or-2? ! ``The heat exchange area of the fins can be expanded commercially by transmitting the heat.

Fig. 21 shows an example of an embodiment of the invention in which a large number of heating elements are provided on a common circuit board or in one body, and each heating element is provided with its own heat dissipation fin. Mei. A large number of spring structures 3-2 are sandwiched between opposing fin planes of a fin group consisting of a fin support body and an annular fin #2 provided on a common circuit board. The invention [Constructing such a fin portion]

In order to simplify the drawing, the tin ring structure is shown in this figure by a line drawn from the center of the spiral. In FIG. 21, each fin portion is characterized in that it is interconnected by a spring structure 3-/ having a tension n in the vertical and horizontal directions.

In the structure of the fin group formed in this way, the entire fin group acts as an integrated fin part, and the fin part when the heating element is at rest acts as a heat dissipation fin for other heating elements, and the circuit It is possible to improve the heat dissipation efficiency of the entire board or the entire housing. In the drawing, the fins are all linearly connected, but in reality, the spring structure may also be formed by filling the gaps between the fins. As such a filling spring ring structure, a two-way spiral spring ring structure is preferable from the point of view of uniformity of fluid distribution.When four parts are connected or filled with each spring structure with one spring structure. , the merciless heating element and each fin section must be electrically connected to the B edge, or the potential between each fin section must be maintained at the same level at all times. And if the annular fin #I'e'' is energized, the fin support is a heat radiator or a heat collector, and heat is exchanged between the heat exchange fluid and the fin support via the fin 1+. It is something to do.

For anchoring, especially for anastomosis, the fin support is simply a fin support, and part of the fin group is used as a heat absorbing member, while the remaining part is used as a heat dissipation part. FIGS. 22 and 23 are a front view and a front view, respectively, of such an embodiment. What n?
A partial cross-sectional view is also shown to clearly indicate the arrangement of the tin ring structure. In the figure, fIeg also has l as a spring structure, 2 as a fin, 3/, 3-. 2゜3-3 is also 2"L with the spring structure. 10 is between each coil of the tin ring structure, or between the tin ring structure and the edge of the fin?
The outer circumferential plane formed by melting and melting with a low-temperature metal such as solder, 11, is a heating element that is layered with a melting layer or a thermally conductive joint material, etc. on the outer circumferential plane IO. The fin structure used in this manner is not practical because the heat transfer area is extremely small if the edges of the fin group are in contact with the entire heating element. Therefore, all pole pieces can be fully inserted into the gap between the opposing fin planes (iH), or low melting point metal) r
J4 k Melt ME, L insert fin]...Fill the gap and make an outer peripheral plane on the outer peripheral edge part? It is common to have a heating element formed on the plane. In this ambiguous case, the shape of the metal piece to be inserted is complicated and the price is high. Fin plane 1
1) Since the gap basin is filled with light, the fin effect in the back part is lost, and since only one gap r is provided with light, the stagnation area of the heat exchange fluid increases, and the fin efficiency as a whole increases. The flaws in the bones are rare.

In the second embodiment of the present invention, the exposed portion of the tin ring structure 3-7 arranged along the fin outer circumference, like the section, may be left as is or the fin outer edge may be formed by applying some pressure. The structure is such that the coils form the same plane as the plane, and the coils such as coils and the edges of the fins are integrally in contact with each other. This integration may be carried out at the same time as the nf and heat body, which are formed in a separate process. Also, this integration can be carried out in practice by connecting it to the preheating body, but it is also possible to extend it to other parts of the 7 as shown in the figure, depending on the situation, and to expand the heat absorption surface. It is. In such a case, heat is absorbed not only from the fin edges but also from the opposing fin planes that are connected by the tin ring structure or clamped by the tin ring structure. 'L.

Although the tin ring structure exhibits its effects even at j-/tall heights, heat absorption is limited to the fin plane and fin support by filling the entire fin gap with the auxiliary tin ring structure 3-1.3-3. The entire surface of the body′? f: go through f
L heat absorption efficiency increases significantly.

The action and effect of the sphere ring structure is large even in the portion corresponding to the contact area of the heating element // for any of the members j-/, J-, 2, and 3-j, as shown in Fig. 23. As shown in the example, if the iron layer is expanded along the circumference of the fin, the heat absorption surface will be sufficiently expanded and the effect of heat absorption will increase depending on the fin. The spring structures j-1, 3-2, and 3-j can be further expanded and filled with all the fin gaps that are not shown in the figure.In this case, The heat dissipation area t is also sufficiently expanded nb.However,
3-/Outer circumferential surface The welding part 10 on the outer circumferential surface must be limited to a portion that does not obstruct the flow of the heat exchange fluid throughout the fin gap. The layered structure according to the present invention does not obstruct the flow of the hot pot fluid within the heat absorbing section, and increases the body flow rate n of the fin group as a whole. There is no increase in the area, and there is no decrease in the fin rate. Furthermore, since the spring structure is readily available for women, there is no fear of an increase in the cost of the entire fin structure. As described above, the inventive arrangement of the heat-generating fins has been considered practical in the past, and it has now become practically possible to directly connect the heating element to the edge of the fin group. I can do it.

As mentioned above, the structure of the silent reversing fin according to the invention 1c depends on many embodiments, including expansion of the heat exchanger such as flat fins and annular fins, a fin structure that allows disassembly and maintenance, and an extremely thin wall. We believe that its effects, such as the formation of fin groups and direct handling of the heating element, will make a significant contribution to the dog.
