Description

  The present invention relates to a vacuum heat insulating material using a metal outer packaging material.

Conventionally, in order to improve the heat resistance of a heat insulating material, a vacuum heat insulating material using a metal outer packaging material has been devised (for example, see Patent Document 1).
Moreover, the vacuum heat insulating material using the resin thing as an outer packaging material has also been devised conventionally (for example, refer patent document 2).
Japanese Patent Laid-Open No. 1-150098 JP-A-7-113494

  However, when the vacuum heat insulating material using the metal outer packaging material described above is attached to an attachment body such as a heating element, it has been performed using a resin such as an adhesive or a double-sided tape. For this reason, although the vacuum heat insulating material itself is excellent in heat resistance, depending on the use conditions, there is a possibility that a problem may occur in long-term adhesiveness. A fixing method to do was necessary. In addition, when a resin having high heat resistance is used, it has to be expensive.

  In addition, even when a metal outer packaging material is used or a resin outer packaging material is used, it is necessary to join and seal the outer packaging materials to form a vacuum, and only the outer packaging material exists. The surplus part, what is called a fin, had to be formed. This surplus portion has no effect on heat insulation, and it has been necessary to bend it or the like so as not to hinder the work of attaching the vacuum heat insulating material.

  Furthermore, the attached body to which the vacuum heat insulating material is attached is often different in shape and size, and when the attached body is changed, the core material of the vacuum heat insulating material or the like is adjusted according to the shape or size of the attached body. The heat insulating material had to be manufactured by changing the shape and size of the outer packaging material.

  The present invention has been made in view of the above points, and its object is to attach a vacuum heat insulating material using a metal outer packaging material at low cost and accurately while maintaining heat resistance. To provide a versatile vacuum heat insulating material that can be used effectively, and the surplus part can be used effectively, and even if the shape and size of the attached body to which the vacuum heat insulating material is attached is changed. is there.

  In order to achieve the above object, in the present invention, an interposition part in which a core part is sandwiched by a metal outer packaging material and a non-interposition part in which the core part is not sandwiched are formed, and an attached body A mounting member for mounting on the non-intervening portion is provided.

Specifically, the vacuum heat insulating material according to the present invention is:
A vacuum heat insulating material including a core material part, and a metal outer packaging material that houses the core material part and can maintain the inside in a reduced pressure state,
An interposition part formed by sandwiching the core part by the metallic outer packaging material facing each other, and a non-intervening part extending from the interposition part and not sandwiched by the metal outer packaging material Formed,
In the non-intervening part, the metal outer packaging material facing each other is joined, and a sealed joint part for sealing the inside of the metal outer packaging material and maintaining the reduced pressure state is formed,
The attachment member for attaching to a to-be-attached body was provided in the said non-intervening part.

  As described above, the vacuum heat insulating material according to the present invention includes a core member and a metal outer packaging material. The metal outer packaging material is capable of housing the core material portion and maintaining the inside in a reduced pressure state.

  Furthermore, the vacuum heat insulating material according to the present invention can be divided into an intervening portion and a non-intervening portion. The intervening part is a part or region formed by sandwiching the core part by metal outer packaging materials facing each other. The non-intervening portion is a portion or a region extending from the intervening portion, and is a portion or a region where the core member is not sandwiched by the metal outer packaging material. Further, a sealing joint is formed in the non-intervening part. Since the non-intervening part does not have a core part, metal outer packaging materials facing each other can be joined. By forming this sealing joint, the inside of the metal outer packaging material can be sealed and maintained in a reduced pressure state.

  Furthermore, an attachment member is provided in the non-intervening portion. An attachment member is for attaching a vacuum heat insulating material to a to-be-attached body.

  Thus, since the attachment member is provided in the non-intervening portion, the vacuum heat insulating material can be attached to the attachment body via the attachment member in a state where the decompressed state is maintained.

The vacuum heat insulating material according to the present invention is
The non-intervening part is
A proximity region that is proximate to the interposition and extends between the interposition and the sealing joint;
A separation region extending away from the interposition part rather than the sealing joint,
What the said attachment member was provided in the said separation area is preferable.

  The non-intervening portion described above is defined in a proximity region and a separation region. The proximity region is a region close to the interposition part and extends between the interposition part and the sealing joint part. Further, the separation region is a region that extends away from the interposition part rather than the sealing joint part. That is, the separation region is a region that exists at a position farther from the proximity region than the intervening portion. The mounting member described above is provided in the separation region.

  Thus, since the attachment member is provided in the separation region, even if the attachment member is provided, the reduced pressure state can be maintained without affecting the reduced pressure state.

Furthermore, the vacuum heat insulating material according to the present invention is
The attachment member has a long shape,
One end of the attachment member is joined to the non-intervening part, and an attachment joint is formed between the metal outer packaging material and the attachment member,
It is preferable that a locking portion for locking to the attached body is formed at another end portion different from the one end portion of the mounting member.

  The mounting member described above has a long shape. One end of the attachment member is joined to the non-intervening part. By attaching one end portion of the attachment member to the non-intervening portion, an attachment joint portion is formed between the metal outer packaging material and the attachment member. Furthermore, the other end part different from the one end part of the attachment member is formed with an engaging part for engaging with the attached body.

  Thus, since one end part of the attachment member is joined to the non-intervening part, a reduced pressure state can be maintained. Furthermore, since the latching | locking part is formed, a vacuum heat insulating material can be accurately attached to a to-be-attached body with an attachment member.

Furthermore, the vacuum heat insulating material according to the present invention is:
The attachment joint is formed between the metal outer packaging materials that are formed to intersect the sealing joint and face each other,
It is preferable that a reduced pressure state is maintained by the attachment joint and the sealing joint.

  Crossing the sealing junction means that it is formed across the above-mentioned proximity region and the separation region. Thus, even if it is formed so as to intersect with the sealing joint portion, the attachment joint portion is also formed between the metal outer packaging materials, so that the reduced pressure state can be maintained.

The vacuum heat insulating material according to the present invention is
The attachment joint and the sealing joint are preferably formed by welding or brazing.

  By forming the attachment joint and the sealing joint by a welding method or brazing, the reduced pressure state can be accurately maintained.

  While maintaining heat resistance, it is possible to attach a vacuum heat insulating material using a metal outer packaging material to a mounted body at a low cost and accurately, and to make effective use of surplus parts, and to attach a vacuum heat insulating material. Even if the shape and size of the attachment are changed, it is possible to provide a versatile vacuum heat insulating material that can cope with the change.

  Embodiments of the present invention will be described below with reference to the drawings.

<<<< first embodiment >>>>
FIG. 1 is a perspective view showing a vacuum heat insulating material 100. FIG. 2 is a front view showing the vacuum heat insulating material 100, and FIG. 3 is a front view showing a state where four attachment members 160 are attached to the vacuum heat insulating material 100. FIG. 4 is a cross-sectional view showing the vacuum heat insulating material 100 along the line II shown in FIG. Note that FIG. 4 shows that there is a gap between adjacent members in order to clearly show the configuration, but in actuality, these members are configured to be in close contact with each other.

  As shown in FIGS. 1-4, the vacuum heat insulating material 100 and the outer packaging material 120 are included. The vacuum heat insulating material 100 can be made by housing the core material portion 110 in the outer packaging material 120 and forming the sealing welding line 130. Details of how to make the vacuum heat insulating material 100 will be described later. In addition, since the welding line 130 for sealing is formed so that it can visually recognize, in FIG. 1-3, it showed with the continuous line. Moreover, since the core material part 110 is covered with the outer packaging material 120, in FIG. 1-3, it showed with the broken line.

<< Core material part 110 >>
<Shape of the core part 110>
As shown in FIGS. 1 and 4, the core member 110 has a substantially thin plate shape. The thickness and size of the core member 110 may be appropriately determined according to the size of an object to be thermally insulated (hereinafter referred to as a mounted body B) and the heat insulating performance required for the mounted body B.

<Material of core part 110>
Although the core material part 110 is not specifically limited, a fiber assembly, an open cell foam, etc. are used. A fiber assembly is preferable from the viewpoint of heat insulation. From the viewpoint of workability, the fiber assembly is preferably used in a substantially plate shape as described above. When the fiber assembly is used as it is in the “wadding state” or in the refined “powdered state”, the handling property of the core material part 110 is deteriorated. The process of storing in 120 becomes complicated and the workability deteriorates.

  The fiber assembly is composed of inorganic fibers, organic fibers, or a mixture thereof.

  Examples of the inorganic fiber include glass fiber (glass wool), alumina fiber, slag wool fiber, silica fiber, rock wool, and the like.

  Examples of organic fibers include polyester fibers, acrylic fibers, polyethylene fibers, polypropylene fibers, nylon fibers, polyvinyl alcohol fibers, polyurethane fibers, polynosic fibers, rayon fibers, and other synthetic fibers, and natural fibers such as hemp, silk, cotton, and wool. Etc. An inorganic fiber and an organic fiber are used as single fiber which consists of 1 type, or multiple types of mixed fiber.

  In the first embodiment, in order to take advantage of the heat resistance of the outer packaging material 120 described later, an inorganic core material excellent in heat resistance is preferable as the core material portion 110. A core material is particularly preferred.

<< Outer packaging material 120 >>
<Shape of outer packaging material 120>
As shown in FIGS. 1 and 2, the outer packaging material 120 is formed by two sheet-shaped outer packaging materials 120a and 120b. Hereinafter, the outer packaging materials 120a and 120b may be simply referred to as the outer packaging material 120.

  Each of the two outer packaging materials 120a and 120b has a certain shape such as a square or a rectangle having the same size. The shape and size of each of the two outer packaging materials 120a and 120b may be appropriately determined according to the shape and size of the core member 110, the shape and size of the non-intervening portion N described later, and the like.

  As will be described later, the two outer packaging materials 120a and 120b are welded so that the two outer packaging materials 120a and 120b overlap each other, and the core material portion 110 is sandwiched between the two outer packaging materials 120a and 120b. By doing so, the vacuum heat insulating material 100 can be made.

<Material of outer packaging material 120>
Any material can be used as the outer packaging material 120 as long as it is a metal that can sufficiently withstand the function of the vacuum heat insulating material 100 under conditions such as temperature and pressure at which the vacuum heat insulating material 100 is used. For example, various steel thin plates such as a mild steel thin plate, a stainless steel thin plate, a galvanized steel thin plate, an aluminum alloy thin plate, a titanium thin plate, a tin thin plate, and the like can be used. In particular, it is preferable to use stainless steel, iron, titanium or the like having a plate thickness of about 0.05 mm to 0.5 mm.

  In addition, the outer packaging material 120 may be configured not only by a single layer of metal thin plate but also by a plurality of layers of metal thin plate. The configuration of the outer packaging material may be appropriately determined in consideration of the heat resistance, the heat insulating property of the core member 110, and the like.

<Sealing welding line 130, intervening portion I, non-intervening portion N (proximity region P, separation region D)>
As will be described later, the vacuum heat insulating material 100 sandwiches the core material portion 110 between the two outer packaging materials 120a and 120b, and welds the two outer packaging materials 120a and 120b along the outer periphery of the core material portion 110. Can be made. As shown in FIGS. 1 to 4, a welding line 130 for sealing can be formed by welding the two outer packaging materials 120 a and 120 b.

  As shown in FIGS. 1 to 3, this sealing welding line 130 (130 a to 130 d) extends from the end of one side of the outer packaging material 120 to the end of the other side facing the one side. , And formed substantially parallel along another side sandwiched between one side and the other side.

  Specifically, the welding line 130a for sealing extends from the end of one side 122d of the outer packaging material 120 to the end of the other side 122b facing the one side 122d, It is formed substantially in parallel along another side 122a sandwiched between the side 122b. The sealing welding line 130b is sandwiched between one side 122a and the other side 122c from the end of one side 122a of the outer packaging material 120 to the end of the other side 122c facing the one side 122a. The other side 122b is formed substantially in parallel. The sealing welding line 130c is sandwiched between one side 122b and the other side 122d from the end of one side 122b of the outer packaging material 120 to the end of the other side 122d facing the one side 122b. It is formed substantially in parallel along another side 122c. The sealing welding line 130d is sandwiched between one side 122c and the other side 122a from the end of one side 122c of the outer packaging material 120 to the end of the other side 122a facing the one side 122c. It is formed substantially in parallel along another side 122d. Note that the four sides 122a to 122d of the outer packaging material 120 described above are denoted by the same reference numerals for the two outer packaging materials 120a and 120b as sides common to the two outer packaging materials 120a and 120b.

  As described above, by forming the welding line for sealing 130 (130a to 130d), the welding line for sealing 130 is formed to circulate around the core part 110, and includes the core part 110. It is possible to accurately seal the region. Since the core material part 110 is interposed in an area where the core material part 110 is included, that is, an area formed by sandwiching the core material part 110 between the two outer packaging materials 120a and 120b (see FIG. 4), This is called an intervening part I. Further, a region where the core part 110 is not sandwiched between the two outer packaging materials 120a and 120b is referred to as a non-intervening part N because the core part 110 is not interposed (see FIG. 4).

  Further, the non-intervening portion N can be divided into a proximity region P and a separation region D by the sealing welding line 130. The proximity region P is a region extending between the interposition part I and the sealing welding line 130. Further, the separation region D is a region extending so as to be farther from the interposition part I than the sealing welding line 130. Therefore, in the vacuum heat insulating material 100 shown in the first embodiment, the proximity region P extends so as to go around the interposition part I, and the separation region D extends so as to go around the proximity region P. To do. Further, the sealing welding line 130 is formed so as to be in contact with both the proximity region P and the separation region D. In other words, the sealing welding line 130 is formed so as to partition and demarcate the proximity region P and the separation region D. In FIG. 2, for the sake of clarity, the proximity region P is shown with a right-down oblique line, and the separation region D is shown with a right-up oblique line.

  As described above, the sealing welding line 130 is formed so as to circulate around the core part 110, and the vacuum heat insulating material 100 is sealed by the sealing welding line 130. That is, both the intervening portion I and the proximity region P are maintained in a reduced pressure state by the sealing welding line 130. This sealing welding line 130 corresponds to a “sealing joint”.

  Further, as described above, both the intervening portion I and the adjacent region P of the vacuum heat insulating material 100 function as a vacuum maintaining region because the decompressed state is maintained. On the other hand, the separation region D is formed so as to go around the intervening portion I and the proximity region P, and the separation region D functions as a non-vacuum region because it is not in a vacuum state.

  As described above, the sealing welding line 130 is formed so as to go around the interposition part I (core material part 110) and the adjacent area P. In particular, the sealing welding line 130 is preferably formed so as not to overlap with the interposition part I (core part 110) and as close as possible to the outer periphery of the interposition part I (core part 110). . As will be described later, the separation region D is for attaching the vacuum heat insulating material 100 to the attachment body B (see FIG. 3 or FIG. 4). As described above, by forming the sealing welding line 130, the separation region D for attaching the vacuum heat insulating material 100 can be ensured accurately, and the interposition part I (core material part 110) can be enlarged. Therefore, the area where the heat insulation effect is exhibited can be enlarged. In the non-intervening portion N (the proximity region P and the separation region D), since the core material portion 110 does not exist, it does not contribute to the heat insulation effect. The non-intervening part N can be effectively utilized by making the separation area D for attaching to the body B to be attached.

  Furthermore, the width of the sealing welding line 130 itself is preferably within 5 mm. If the conventional outer packaging material inner layer is heat-sealed, the wider the width, the better the long-term heat insulation performance. Therefore, the width required for heat-sealing is usually about 10 mm. However, in the present invention, since the vacuum heat insulating material 100 is attached to the attachment body B using the separation region D divided by the sealing welding line 130, it is preferable as the heat insulation efficiency to provide a non-existing portion more than necessary. It is preferable to reduce the width of the sealing welding line 130 itself. Especially preferably, it is 0.5-3 mm.

  Further, the width of the non-intervening portion N is not particularly limited depending on the size of the vacuum heat insulating material, but is about 3 to 70 mm, and preferably 10 to 40 mm from the viewpoint of heat insulating efficiency and mounting property. is there.

  The sealing welding line 130 described above corresponds to a “sealing joint”.

<< Getter Agent 150 >>
<Function of getter agent 150>
A getter agent 150 (not shown) may be provided in the outer packaging material 120. After depressurizing the inside of the outer packaging material 120 and welding it, gas, for example, outgas or moisture may be generated from the core material portion 110 inside the outer packaging material 120, which may reduce the degree of vacuum. For this reason, it is preferable to store the getter agent 150 capable of adsorbing gas and moisture together with the core member 110 in the outer packaging material 120.

  Thus, by storing the getter agent 150 in the outer packaging material 120, gas and moisture can be absorbed by the getter agent 150, so that the heat insulating effect of the vacuum heat insulating material 100 can be maintained for a longer time.

<Material of getter agent 150>
The substance capable of adsorbing gas and moisture is not particularly limited, and examples of substances that physically adsorb gas and moisture include activated carbon, silica gel, aluminum oxide, molecular sieve, and zeolite. Also, those that chemically adsorb gas or moisture include, for example, calcium oxide, barium oxide, calcium chloride, magnesium oxide, magnesium chloride, metal powder materials such as iron and zinc, barium-lithium alloys, zirconium There are system alloys.

<< Vacuum insulation 100 >>
The vacuum heat insulating material 100 can be made as follows.

  First, two metal outer packaging materials 120a and 120b having substantially the same size are prepared, and these two outer packaging materials 120a and 120b are arranged so as to approximately overlap. Next, the core material part 110 is sandwiched between the two outer packaging materials 120a and 120b, and the core material part 110 is positioned so as to be located at a substantially central portion of the outer packaging materials 120a and 120b. Finally, the welding line 130 for sealing is formed by welding the two outer packaging materials 120a and 120b so as to go around the core member 110 along the outer periphery 122 of the core member 110. When the sealing welding line 130 is formed, the core member 110 and the two outer packaging materials 120a and 120b are welded in a vacuum state, so-called vacuum welding. By doing in this way, the vacuum heat insulating material 100 which made the inside the pressure reduction state can be made, and a pressure reduction state can be maintained by welding the two outer packaging materials 120a and 120b.

  As long as welding can join two outer packaging materials 120a and 120b, any kind of welding such as arc welding, electron beam welding, and resistance welding may be used. For example, there are pressure bonding methods such as seam welding, butt welding such as TIG welding, MIG brazing, and the like. In particular, it is preferable to use a welding method that does not generate gas or the like from the sealing welding line 130 that is a joint even in a vacuum state or a high temperature state.

  In the above-described example, the joint is formed by welding as the sealing welding line 130, but may be formed by soldering or brazing. What is necessary is that the inside of the vacuum heat insulating material 100, that is, the interposition part I and the proximity part P can be kept in a reduced pressure state and the sealing can be maintained.

<< Mounting member 160 >>
The attachment member 160 is a member for attaching the vacuum heat insulating material 100 to the attachment body B. The attachment member 160 is manufactured separately from the vacuum heat insulating material 100. As will be described later, first, the attachment member 160 is attached to the vacuum heat insulating material 100, and the vacuum heat insulating material 100 to which the attachment member 160 is attached is attached to the attachment body B via the attachment member 160.

<Form of mounting member 160>
As shown in FIGS. 3 and 4, the attachment member 160 has a thin plate shape and a substantially rectangular shape. Thus, since the mounting member 160 has a substantially rectangular shape, the outer shape of the mounting member 160 is two short sides 166a and 166b (the length in the longitudinal direction of the mounting member 160) facing each other. The length of the mounting member 160 in the short direction).

  As shown in FIG. 3, the end of one short side 166 a of the two short sides facing each other is used to be attached to the vacuum heat insulating material 100. In particular, it is preferably attached to the separation region D of the vacuum heat insulating material 100. Since it is attached to the separation region D of the vacuum heat insulating material 100, even if processing such as processing for attaching the mounting member 160 is performed, the reduced pressure state of the vacuum heat insulating material 100 is not affected, and the vacuum heat insulating material 100 is sealed. Can be maintained. Note that the end portion of the short side 166 a means a region required to attach the attachment member 160 to the vacuum heat insulating material 100. The attachment of the attachment member 160 to the vacuum heat insulating material 100 will be described later.

  On the other hand, a through-hole 162 that penetrates the attachment member 160 is formed at the end of the other short side 166 b of the two short sides of the attachment member 160. The vacuum heat insulating material 100 can be attached to the body to be attached B (see FIG. 5) through a screw, caulking or the like through the through-hole 162. In the above-described example, the through hole 162 is formed at the end of the short side 166b. However, it is only necessary that the vacuum heat insulating material 100 can be attached to the attachment body B, so the end of the short side 166b is attached. What has the latching | locking part which can be latched to the to-be-attached body B should just be. For example, an L-shaped or U-shaped hook or the like may be formed at the end of the short side 166b. The end portion of the short side 166b described above means a region required to form a locking portion such as the through hole 162.

  As described above, the attachment member 160 shown in FIGS. 3 and 4 has a thin plate shape and a substantially rectangular shape. However, as described above, the attachment member 160 covers the vacuum heat insulating material 100. Since it is for attaching to the attachment body B, it has two ends, one end of which is configured as a fixed end to be attached to the vacuum heat insulating material 100 and the other end is attached to the attachment body B What is necessary is just to be comprised as a latching end provided with this latching | locking part. In the above-described example, one end of the attachment member 160 is configured as a fixed end for being attached to the vacuum heat insulating material 100, and the other end is configured as a locking end for being attached to the attachment body B. One end may be configured as a fixed end to be attached to the attachment body B, and the other end may be configured as a locking end to be attached to the vacuum heat insulating material 100.

<Material of mounting member 160>
The attachment member 160 is made of metal. For example, the attachment member 160 can be made of a metal such as aluminum or stainless steel. By constituting the attachment member 160 with metal, it can be attached to the outer packaging material 120 made of metal by welding, soldering, or brazing, and attaching the attachment member 160 to the vacuum heat insulating material 100 accurately and firmly. Can do. The attachment member 160 may be attached to the vacuum heat insulating material 100 as long as metals can be joined together.

<Form and material of mounting member 160>
About the thickness and material of the attachment member 160 mentioned above, what can be cut | disconnected with cutting tools, such as a metal cutting scissors, for example, the thing made from aluminum of about 1 mm is preferable. As will be described later, by making it possible to cut with a cutting tool, the mounting member 160 attached in advance to the vacuum heat insulating material 100 is removed from the vacuum heat insulating material 100, and another mounting member 160 is attached to the vacuum heat insulating material 100. It can be attached at a desired position. By being able to do in this way, the vacuum heat insulating material 100 in a state shipped from the factory is not simply used, but the vacuum heat insulating material 100 in a state shipped from the factory is installed on the attachment site B. Depending on the shape and size, the attachment position of the member 160 can be changed to a desired position.

  The length, width, thickness, and material of the attachment member 160 are appropriately determined according to the size, shape, weight, and material of the vacuum heat insulating material 100, the size and shape of the attachment B, the environment in which it is used, and the like. Just do it. That is, what is necessary is just to be able to maintain desired heat insulation over a desired period in an environment where the vacuum heat insulating material 100 is used.

<Attaching the attachment member 160>
A state in which the four attachment members 160 are attached to the vacuum heat insulating material 100 is shown in FIG. The attachment member 160 is attached to four locations in the separation region D of the vacuum heat insulating material 100. As described above, by attaching to the separation region D of the vacuum heat insulating material 100, even if processing such as processing for attaching the mounting member 160 is performed, the vacuum without affecting the reduced pressure state of the vacuum heat insulating material 100. The sealing state of the heat insulating material 100 can be maintained. The vacuum heat insulating material 100 is attached to the attachment body B through the four attachment members 160.

  As described above, the outer packaging material 120 of the vacuum heat insulating material 100 is made of metal, and the attachment member 160 is also made of metal. For this reason, the attachment member 160 can be attached to the outer packaging material 120 of the vacuum heat insulating material 100 by welding, soldering, or brazing. In this manner, the attachment joint portion 164 is formed by attaching the attachment member 160 to the outer packaging material 120 of the vacuum heat insulating material 100. As shown in FIG. 3, the attachment joint 164 is formed so as to straddle the attachment member 160. In the example shown in FIG. 3, the attachment joint portion 164 is formed not only at a place where the attachment member 160 exists but also at a place where the attachment member 160 does not exist along the vertical direction of the paper surface. By doing in this way, the length by which the attachment member 160 and the outer packaging material 120 of the vacuum heat insulating material 100 are joined by the attachment joining portion 164 can be increased, and the area and area can be increased, thereby strengthening the joining. Can be. Furthermore, since the attachment joint portion 164 is formed including a portion where the attachment member 160 does not exist, the force applied to the attachment member 160 can be dispersed in a wider region, and the attachment strength of the attachment member 160, etc. By maintaining the attachment state for a long period of time, the reduced pressure state of the vacuum heat insulating material 100 can be maintained for a long period of time.

  As described above, the attachment joint portion 164 can be formed by attaching the attachment member 160 to the vacuum heat insulating material 100 by welding, soldering, or brazing. The attachment joint 164 may be formed only between the attachment member 160 and the outer packaging material 120, but between the attachment member 160 and the outer packaging material 120 and between the two outer packaging materials 120a and 120b. It is preferable to form both of them (see FIGS. 4A and 4B). Thus, by forming the attachment joint 164 not only between the attachment member 160 and the outer packaging material 120 but also between the outer packaging materials 120a and 120b, the attachment member 160 is attached to the vacuum heat insulating material 100. In addition to being able to attach more firmly, the force applied to the attachment member 160 can be distributed to both of the two outer packaging materials 120a and 120b, making it difficult to damage the vacuum heat insulating material 100 and attaching. By maintaining the attachment state such as the attachment strength of the member 160 over a long period of time, the reduced pressure state of the vacuum heat insulating material 100 can be maintained over a long period of time.

  Further, as shown in FIGS. 3 and 4, the attachment member 160 is preferably attached to the vacuum heat insulating material 100 such that a part of the attachment member 160 protrudes or extends from the outer periphery of the vacuum heat insulating material 100. . By attaching in this way, the attachment work to the to-be-attached body B of the vacuum heat insulating material 100 can be made easy. Further, by bending or curving the protruding or extending mounting member 160 into an L shape, it can be adapted to the shape, size, etc. of the mounting body B. The attachment work to the attachment body B can be further facilitated. Furthermore, by positioning the through-hole 162 at a position where it protrudes from or extends from the vacuum heat insulating material 100, the work of attaching the vacuum heat insulating material 100 to the mounted body B can be made easier and simpler.

  In the example shown in FIG. 3, the attachment member 160 is attached so as to protrude or extend from the vacuum heat insulating material 100 along the surface direction of the vacuum heat insulating material 100 (direction parallel to the paper surface). However, since the attachment member 160 may differ depending on the position and size of the attachment body B, for example, along the direction perpendicular to the surface of the vacuum heat insulating material 100 (direction perpendicular to the paper surface). The attachment member 160 may be attached so as to protrude or extend from the vacuum heat insulating material 100. By doing in this way, it can make it easy to adapt to the shape of a to-be-attached body B, a magnitude | size, etc., and the attachment work to the to-be-attached body B of the vacuum heat insulating material 100 is made easy and simple. Can do.

  As described above, the outer shape of the attachment member 160 has a thin and long plate shape. A single thin plate-like plate may be used, or a plurality of plates may be stacked. For example, FIG. 4A is a diagram illustrating an example in which the attachment member 160 is configured by one thin plate-like long plate, and FIG. 4B is a diagram showing two thin plate-like long plates. It is a figure which shows the example which comprised the attachment member 160 by overlapping a board. 4A and 4B are cross-sectional views showing the vacuum heat insulating material 100 taken along line II shown in FIG. 4 (a) and 4 (b), the same reference numerals are given and the mounting members 160 are shown.

  As shown in FIG. 4A, when the attachment member 160 is configured by a single thin plate-like long plate, the attachment member 160 is attached to one side of the separation region D of the vacuum heat insulating material 100. As described above, the attachment member 160 only needs to be attached to one side of the separation region D, and therefore the attachment of the attachment member 160 can be facilitated.

  Further, as shown in FIG. 4B, when the attachment member 160 is configured by two thin plate-like long plates, they are attached so as to sandwich the separation region D of the vacuum heat insulating material 100. When the attachment member 160 is attached so as to sandwich the separation region D in this way, the attachment member 160 can be firmly attached to the separation region D.

  As described above, the attachment member 160 is attached to the vacuum heat insulating material 100 by welding, soldering, or brazing. Thus, by attaching the attachment member 160 to the vacuum heat insulating material 100, the area to which the attachment member 160 is attached can be reduced, so that the width W1 (see FIG. 3) of the separation region D can be shortened. Can be small. Furthermore, since the interposition part I can be enlarged by the amount of the separation area D being reduced, that is, the core part 110 can be enlarged, the entire area of the vacuum heat insulating material 100 that contributes to heat insulation is increased. The heat insulation efficiency of the vacuum heat insulating material 100 can be increased.

  The attachment member 160 is attached to the separation region D. Since the core part 110 does not exist, the separation region D is an excessive part as the vacuum heat insulating material 100. By attaching the attachment member 160 to the separation region D, the separation region D can be effectively utilized.

  As described above, since the separation region D can be reduced, the non-intervening portion N can also be reduced. This non-intervening part N is also an excessive part as the vacuum heat insulating material 100 because the core part 110 does not exist. Since the non-intervening portion N that is an excessive portion can be reduced, it can be easily adapted to the shape and size of the attached body B, and the handling of the vacuum heat insulating material 100 can be simplified.

  Moreover, the attachment body which attaches a vacuum heat insulating material has a shape and a size different in many cases according to the use and purpose of the apparatus. For this reason, when the vacuum heat insulating material and the mounting member are manufactured so as to be integrated in advance, the shape and size of the core material and the outer packaging material are determined according to the shape and size of the mounting body, and the mounting member is It is necessary to remanufacture the entire vacuum heat insulating material. However, by configuring as in the present application, first, the vacuum heat insulating material 100 and the mounting member 160 are manufactured separately, and are attached at positions corresponding to the shape and size of the mounted body B in the final manufacturing process. The member 160 may be attached to the vacuum heat insulating material 100. By doing in this way, the kind of vacuum heat insulating material which should be manufactured can be decreased, and productivity can be improved.

<< Attachment of Vacuum Insulating Material 100 to Substrate B >>
FIG. 5 is a diagram showing a mode of attaching the vacuum heat insulating material 100 to the attached body B. FIG. FIG. 5A is a diagram showing a case where the vacuum heat insulating material 100 is attached to the attachment body B without being bent as it is, and FIG. 5B is a diagram illustrating a case where the non-intervening portion N of the vacuum heat insulating material 100 is attached. It is a figure which shows the case where it folds together with the external shape of the body B, and attaches to the to-be-attached body B. FIG. In this way, the vacuum heat insulating material 100 may be used as it is or bent and used depending on the size and shape of the attached body B, the location to be insulated, and the like. In both cases shown in FIGS. 5 (a) and 5 (b), a screw 170 is passed through a through-hole 162 formed in the attachment member 160 and fixed to the attachment body B. The vacuum heat insulating material 100 is fixed by securing the heat resistance so that the non-intervening portion N of the vacuum heat insulating material 100 is in close contact with the mounted body B, such as fixing with a screw 170 in addition to the screw 170. I can do it.

  In the example shown in FIG. 5B described above, the case where the non-intervening portion N of the vacuum heat insulating material 100 is folded is shown. May be bent and attached to the attachment B. Even in such a case, it is only necessary that the non-intervening portion N of the vacuum heat insulating material 100 can be fixed so that the non-intervening portion N is in close contact with the attached body B and heat resistance is secured.

<< Change of mounting position of mounting member 160 >>
As described above, the vacuum heat insulating material 100 and the mounting member 160 are manufactured separately, and the mounting member 160 is placed at a position corresponding to the shape and size of the mounted body B in the final manufacturing process. Attach to. Therefore, at the stage of shipment from the factory, the attachment member 160 attached to the vacuum heat insulating material 100 (see FIG. 3) is shipped. Thus, although the attachment member 160 is attached to the vacuum heat insulating material 100 at a position corresponding to the shape and size of the attachment body B, there is still a need to change the position of the attachment member 160 in the field. It may occur. Below, the response | compatibility in such a case is demonstrated.

  As described above, the thickness and material of the attachment member 160 are preferably those that can be cut with a cutting tool such as a gold scissors, for example, those made of aluminum having a thickness of about 1 mm. Thus, by making it possible to cut with the cutting tool, the attachment member 160 attached in advance to the vacuum heat insulating material 100 can be removed from the vacuum heat insulating material 100 (see the attachment member 160 ′ in FIG. 6). Furthermore, a separately prepared attachment member 160 can be attached to a desired position of the vacuum heat insulating material 100 in accordance with the shape and size of the attached body B (see the attachment member 160 ″ in FIG. 6). Therefore, not only the vacuum heat insulating material 100 shipped from the factory is used as it is, but also the vacuum heat insulating material 100 shipped from the factory is used in accordance with the shape and size of the mounted body B. The mounting position can be changed to a desired position at the mounting site, whereby the usage of the vacuum heat insulating material 100 can be improved.

<<< Second Embodiment >>>
In the first embodiment described above, the attachment member 160 is attached to the side of the vacuum heat insulating material 100. On the other hand, in the vacuum heat insulating material 200 of 2nd Embodiment, the attachment member 260 is attached to the four corners of the vacuum heat insulating material 200. FIG. In the second embodiment shown in FIG. 7, elements common to the first embodiment are denoted by the same reference numerals.

  The vacuum heat insulating material 200 in the second embodiment has the same configuration as the vacuum heat insulating material 100 in the first embodiment described above. That is, the material and the size of the core material part 110 and the outer packaging material 120 are the same, and a getter agent 150 may also be provided. Therefore, the sealing welding line 130 is also formed in the same manner, and the intervening portion I, the non-intervening portion N, the proximity region P, and the separation region D are also formed in the same manner as the vacuum heat insulating material 100. Play. Further, the attachment member 260 in the second embodiment has the same configuration as the attachment member 160 in the first embodiment except that the dimensions are different. That is, the attachment member 260 has a thin plate shape and a substantially rectangular shape, and is made of metal.

  As described above, by forming the vacuum heat insulating material 200 and the attachment member 260, the outer packaging material 120 of the vacuum heat insulating material 200 is made of metal, and the attachment member 260 is also made of metal. By doing in this way, also when attaching the attachment member 260 to the vacuum heat insulating material 200, it can attach to the outer packaging material 120 comprised with the metal by welding, soldering, or brazing. By attaching the attachment member 260 to the vacuum heat insulating material 200 in this manner, the attachment joint 264 is formed. As shown in FIG. 7, the attachment joint 264 is formed so as to straddle the attachment member 260. In the example shown in FIG. 7, the attachment joint 264 is formed obliquely so as to intersect with each of the two sealing welding lines 130. Specifically, the attachment joint 264a for attaching the attachment member 260a is formed obliquely so as to intersect each of the two sealing welding lines 130a and 130b. Further, the attachment joint portion 264b for attaching the attachment member 260b is formed obliquely so as to intersect each of the two sealing welding lines 130b and 130c. Further, the attachment joint portion 264c for attaching the attachment member 260c is formed obliquely so as to intersect each of the two sealing welding lines 130c and 130d. Furthermore, the attachment joint 264d for attaching the attachment member 260d is formed obliquely so as to intersect each of the two sealing welding lines 130d and 130a.

  As described above, the attachment joint portion 264 is formed in both the proximity region P and the separation region D by forming the attachment joint portion 264 obliquely so as to intersect with each of the two sealing welding lines 130. It will be formed across. Therefore, in the second embodiment, the attachment joint 264 is formed not only between the attachment member 260 and the outer packaging material 120 but also between the two outer packaging materials 120a and 120b. It is preferable to do this. By doing so, even when a force is applied to the attachment member 260, the attachment joint 264 is formed between the two outer packaging materials 120a and 120b, so that the applied force is dispersed. In addition, the outer packaging materials 120a and 120b can be made difficult to break. Furthermore, in the proximity region P, the attachment joint portion 264 formed between the two outer packaging materials 120a and 120b is formed at a position closer to the core material portion 110 than the sealing welding line 130. A new welding line for sealing can be formed by the attachment joint 264 formed between the outer packaging materials 120a and 120b. By doing in this way, since the sealing welding line can be formed twice, not only can the vacuum state be prevented from being broken from the four corners of the vacuum heat insulating material 200, but also the mounting strength of the mounting member 260, etc. The attachment state can be maintained for a longer period, the reduced pressure state of the vacuum heat insulating material 200 can be maintained for a longer period, and the reduced pressure state can be more reliably maintained.

<<< Third Embodiment >>>
In the first embodiment and the second embodiment described above, the case where the vacuum heat insulating materials 100 and 200 are used as a single sheet is shown, but a plurality of these vacuum heat insulating materials may be used continuously. .

  FIG. 8 is a front view showing a vacuum heat insulating material 300 in which two vacuum heat insulating materials 100 are connected. In the third embodiment shown in FIG. 8, elements that are the same as those in the first embodiment are denoted by the same reference numerals.

  The single vacuum heat insulating material 100 constituting the vacuum heat insulating material 300 in the third embodiment has the same configuration as the vacuum heat insulating material 100 in the first embodiment described above. That is, the material and the size of the core material part 110 and the outer packaging material 120 are the same, and a getter agent 150 may also be provided. Therefore, the sealing welding line 130 is also formed in the same manner, and the intervening portion I, the non-intervening portion N, the proximity region P, and the separation region D are also formed in the same manner as the vacuum heat insulating material 100. Play. Further, the mounting member 160 in the first embodiment has the same configuration as the mounting member 160 in the first embodiment. That is, the attachment member 160 has a thin plate shape and a substantially rectangular shape, and is made of metal.

<Form of connecting member 380>
The two vacuum heat insulating materials 100 shown in FIG. 8 are connected by a connecting member 380. As shown in FIG. 8, the connecting member 380 has a thin plate shape and a substantially rectangular shape. Thus, since the connecting member 380 has a substantially rectangular shape, the outer shape of the connecting member 380 has two short sides 382a and 382b (the length in the longitudinal direction of the connecting member 380) facing each other. The length of the connecting member 380 in the short direction).

  As shown in FIG. 8, both ends of the two short sides 382 a and 382 b facing each other are used to be attached to the vacuum heat insulating material 100. In this case, it is preferable to attach to the separation area D of the vacuum heat insulating material 100. Since it is attached to the separation region D of the vacuum heat insulating material 100, even if processing such as processing for attaching the connecting member 380 is performed, the reduced pressure state of the vacuum heat insulating material 100 is not affected, and the vacuum heat insulating material 100 is sealed. Can be maintained. Here, the end portions of the short sides 382 a and 382 b mean regions required to attach the connecting member 380 to the vacuum heat insulating material 100.

  Furthermore, a through-hole 384 that penetrates the connecting member 380 is formed in the approximate center of the connecting member 380. The two vacuum heat insulating materials 100 can be attached to the body to be attached B (not shown) through screws, caulking or the like through the through holes 384. In the above-described example, the through hole 384 is formed in the approximate center of the connecting member 380. However, since the two vacuum heat insulating materials 100 may be attached to the attachment body B, the attachment body B is not limited. What is necessary is just to have the latching | locking part which can be latched in the approximate center of the connection member 380. For example, an L-shaped or U-shaped hook may be formed at the approximate center of the connecting member 380. The approximate center of the connecting member 380 described above means a region required to form a locking portion such as the through hole 384.

<Material of connecting member 380>
The connecting member 380 is made of metal. For example, the connecting member 380 can be made of a metal such as aluminum or stainless steel. By constituting the connecting member 380 with metal, it can be attached to the outer packaging material 120 made of metal by welding, soldering or brazing, and the connecting member 380 is attached to the vacuum heat insulating material 100 accurately and firmly. Can do. In addition, the attachment to the vacuum heat insulating material 100 of the connection member 380 should just be what can join metals.

<Form and material of connecting member 380>
The length, width, thickness, and material of the attachment member 160 are appropriately determined according to the size, shape, and weight of the vacuum heat insulating material 100, the size and shape of the attachment B, the environment in which it is used, and the like. Just do it. That is, what is necessary is just to be able to maintain desired heat insulation over a desired period in an environment where the vacuum heat insulating material 100 is used.

<Attaching the connecting member 380>
FIG. 8 shows a state where the two connecting members 380 are attached between the two vacuum heat insulating materials 100. The connecting member 380 is attached to the separation region D of the vacuum heat insulating material 100. As described above, even if processing such as processing for attaching the connecting member 380 is performed by attaching to the separation region D of the vacuum heat insulating material 100, the vacuum without affecting the reduced pressure state of the vacuum heat insulating material 100. The sealing state of the heat insulating material 100 can be maintained. The two vacuum heat insulating materials 100 can be connected to each other and attached to the attachment body B by the connecting member 380.

  As described above, the outer packaging material 120 of the vacuum heat insulating material 100 is made of metal, and the connecting member 380 is also made of metal. For this reason, the attachment member 160 can be attached to the outer packaging material 120 of the vacuum heat insulating material 100 by welding, soldering, or brazing. In this manner, the attachment joint 386 is formed by attaching the connecting member 380 to the outer packaging material 120 of the vacuum heat insulating material 100. As shown in FIG. 8, the attachment joint 386 is formed so as to straddle the connecting member 380. In the example shown in FIG. 8, the connecting member 380 is formed not only at a location where the connecting member 380 exists, but also at a location where the connecting member 380 does not exist, along the left-right direction of the drawing. By doing in this way, the length by which the connection member 380 and the outer packaging material 120 of the vacuum heat insulating material 100 are joined by the attachment joining portion 386 can be increased, and the region and the area can be increased. Can be. Furthermore, since the attachment joint portion 386 is formed including a portion where the connecting member 380 does not exist, the force applied to the connecting member 380 can be dispersed in a wider region, and the attachment strength of the connecting member 380, etc. By maintaining the attachment state for a long period of time, the reduced pressure state of the vacuum heat insulating material 100 can be maintained for a long period of time.

  As described above, the attachment joint 386 can be formed by attaching the connecting member 380 to the vacuum heat insulating material 100 by welding, soldering, or brazing. The attachment joint 386 may be formed only between the connecting member 380 and the outer packaging material 120, but between the connecting member 380 and the outer packaging material 120 and between the two outer packaging materials 120a and 120b. It is good to make it form both. In this way, by forming the attachment joint 386 not only between the coupling member 380 and the outer packaging material 120 but also between the outer packaging materials 120a and 120b, the coupling member 380 is attached to the vacuum heat insulating material 100. It can be attached more firmly, and the force applied to the connecting member 380 can be distributed to both of the two outer packaging materials 120a and 120b, making it difficult to damage the vacuum heat insulating material 100 and mounting. By maintaining the attachment state such as the attachment strength of the member 160 over a long period of time, the reduced pressure state of the vacuum heat insulating material 100 can be maintained over a long period of time.

  Further, the connecting member 380 is preferably one that can be bent or bent into an L shape. By doing in this way, the shape of the connecting member 380 can be adapted to the shape of the attached body B, etc., and the attaching operation of the vacuum heat insulating material 100 to the attached body B can be further facilitated by the connecting member 380. can do.

<<< Fourth embodiment >>>>
In any of the first to third embodiments described above, the sealing welding line 130 is formed outside the core member 110. However, the outer shape of the attached body to which the vacuum heat insulating material is attached is not limited to the case where the outer shape is constituted by a plane. For example, a pipe such as a pipe or a hose for exhaust or intake air may be connected to the attached body. Even if the mounted body has such a configuration or structure, it may be necessary to insulate the mounted body. In such a case, a through-hole for allowing piping to pass through is also formed in the core material portion, and it is necessary to seal the periphery of the through-hole.

  FIG. 9 is a front view showing a vacuum heat insulating material 400 according to the fourth embodiment. In the fourth embodiment shown in FIG. 9, elements that are the same as those in the first embodiment are denoted by the same reference numerals.

  The vacuum heat insulating material 400 according to the fourth embodiment includes a core material portion 410 and an outer packaging material 420. The outer packaging material 420 includes two outer packaging materials 420a and 420b. The vacuum heat insulating material 400 can be made in the same manner as the vacuum heat insulating material 100 of the first embodiment. The core material part 410 and the outer packaging material 420 are the same as the core material part 110 and the outer packaging material 120 of the first embodiment except that an opening is formed. The material and size are the same, and a getter agent 150 may also be provided. Also, the sealing welding line 130 is formed in the same manner, and the intervening portion I4, the non-intervening portion N, the proximity region P, and the separation region D are formed in the same manner as the vacuum heat insulating material 100, and these have the same functions and functions. . The interposition part I4 is the same as the interposition part I in the first embodiment, except that an opening is formed. Further, the mounting member 160 in the first embodiment has the same configuration as the mounting member 160 in the first embodiment. That is, the attachment member 160 has a thin plate shape and a substantially rectangular shape, and is made of metal.

  As described above, the core material portion 410 and the outer packaging material 420 are formed with openings. For this reason, as shown in FIG. 9, an opening 470 is formed in the vacuum heat insulating material 400. Note that the size and position of the opening 470 may be appropriately determined according to the size and position of the pipe attached to the attached body B ′ (see FIG. 10). The vacuum heat insulating material 400 can be attached to the attachment body B ′ by passing through a pipe such as a pipe or a hose through the opening 470.

  The interposition part I4 can be formed by sandwiching the core part 410 between the two outer packaging materials 420a and 420b. Further, the substantially annular region around the opening 470 is a region where the core member 410 does not exist, and is a non-intervening portion N4. In the non-intervening part N4, the welding line 430 for sealing can be formed by welding these two outer packaging materials 420a and 420b in a circular shape. By forming this sealing welding line 430, the non-intervening portion N4 can be divided into a proximity region P4 and a separation region D4. The proximity region P4 is a region extending between the interposition part I4 and the sealing welding line 430. Further, the separation region D4 is a region that extends away from the interposition part I rather than the welding line 430 for sealing. Therefore, in the vacuum heat insulating material 400 shown in the fourth embodiment, the separation region D4 extends so as to go around the opening 470, and the proximity region P4 extends so as to go around the separation region D4. . Further, the sealing welding line 430 is formed so as to be in contact with both the proximity region P4 and the separation region D4. In other words, the sealing welding line 430 is formed so as to partition and demarcate the proximity region P4 and the separation region D4.

  As described above, in addition to the sealing welding line 430, the sealing welding line 130 is also formed in the vacuum heat insulating material 400. Therefore, the vacuum heat insulating material 400 is sealed by the two sealing welding lines 130 and the sealing welding line 430. That is, the three regions of the interposition part I4, the proximity region P, and the proximity region P4 are maintained in a reduced pressure state by the two sealing welding lines 130 and the sealing welding line 430. The sealing welding line 130 and the sealing welding line 430 correspond to the “sealing joint”.

  Further, as described above, the three regions of the intervening portion I4, the proximity region P, and the proximity region P4 of the vacuum heat insulating material 400 function as a vacuum maintenance region because the decompressed state is maintained. On the other hand, the separation regions D and D4 function as non-vacuum regions because they are not in a vacuum state.

  Four attachment members 160 are attached to the separation region D4 described above. Note that the four attachment members 160 attached to the separation region D4 have the same configuration as the four attachment members 160 attached to the separation region D. That is, the attachment member 160 has a thin plate shape and a substantially rectangular shape, and is made of metal. Therefore, the four attachment members 160 attached to the separation region D4 can be attached in the same manner as the four attachment members 160 attached to the separation region D.

  FIG. 10 shows a state where the vacuum heat insulating material 400 is attached to the attachment body B ′. Since the attached body B 'in the fourth embodiment is provided with a pipe L or the like, an opening 600 is also formed in the attached body B'. In addition, in FIG. 10, the piping L was shown with the broken line. As shown in FIG. 10, the non-intervening portion N of the vacuum heat insulating material 400 is bent by approximately 90 degrees toward the opening 600 formed in the attached body B ′. A screw hole 610 corresponding to the through hole 162 formed in the attachment member 160 is formed in the opening 600. By passing the screw 170 through the through-hole 162 formed in the attachment member 160 and screwing the screw 170 into the screw hole 610, the vacuum heat insulating material 400 can be attached to the attachment body B '.

  Note that FIG. 10 shows only the portions to be attached to the attachment body B ′ using the four attachment members 160 attached to the separation region D4. However, the four attachment members 160 attached to the separation region D are shown in FIG. The vacuum heat insulating material 400 can be attached to the body B ′ to be attached in the same manner as in FIG. 5A or 5B shown in the first embodiment.

  Thus, the vacuum heat insulating material 400 can be attached to the attached body B ′ to which piping or the like is attached, and the attached body B ′ can be insulated accurately.

  In the example shown in FIG. 10 described above, the case where the non-intervening portion N of the vacuum heat insulating material 400 is attached by being bent (inward) toward the opening 600 formed in the attached body B ′ is shown. The non-intervening portion N of the material 400 may be attached by being bent toward the opposite side of the opening 600 formed in the attached body B ′ (outward) by approximately 90 degrees. In this case, the four attachment members 160 can be directly attached to the pipe L, or a member such as an annular adapter can be attached to the pipe L, and the four attachment members 160 can be attached to the members.

It is a perspective view which shows the vacuum heat insulating material 100 by 1st Embodiment. It is a front view which shows this vacuum heat insulating material.
