Description

  The present invention relates to a vacuum thermal insulation panel using a vacuum thermal insulation material, and more specifically to a vacuum thermal insulation panel with a sensor provided with a wireless sensor.

  In recent years, vacuum heat insulating materials having higher heat insulating performance than polystyrene foam are frequently used as heat insulating materials. This vacuum heat insulating material is a core material made of a porous body having a large number of voids inside, and is covered with a gas barrier outer covering material to reduce the pressure, and the opening of the outer covering material is thermally welded (heat sealed). . Thus, it is the heat insulating material which improved the heat insulation performance by making the inside into a vacuum state (state with a high degree of vacuum) by decompression. In addition, the heat conductivity of a vacuum heat insulating material is 0.002-0.01 w / mk, and the heat insulation performance is remarkable compared with 0.02-0.03 w / mk of a polystyrene foam, and 0.02 w / mk of air. It can be seen that it is.

  This vacuum insulation material is used in many fields such as refrigerators and magic bottles, as well as building materials used in the walls of freezer rooms, and forms a space that is thermally insulated from the outside. It is used in every scene as a wall material (panel).

  On the other hand, there is also a demand for managing the temperature in a space thermally insulated from the outside (hereinafter referred to as “heat insulation space”). However, for the following reasons, conventionally, a technique called temperature management in which a battery-type temperature sensor is arranged in an adiabatic space has not been adopted. First, there is a problem of battery life. It is known that the battery is likely to deteriorate in a low temperature (high temperature) environment or a high humidity environment, and the life is extremely shortened. In general, the heat insulation space is a low temperature environment or a high temperature environment, and in some cases, a high humidity environment is accompanied by the installation of dry ice or the like.

  Secondly, there is a problem of difficulty in confirming the measurement result of the temperature sensor. The heat insulation space needs to avoid heat exchange with the outside, and it is not allowed to open and close a part of the heat insulation space (for example, a lid or a door) every time the measurement result of the temperature sensor is confirmed. That is, when a temperature sensor is installed in the heat insulation space, it is not easy to confirm the measurement result.

  For these reasons, there has been no proposal for a technique that uses a vacuum heat insulating material and performs temperature control using a temperature sensor or the like. Rather, as in Patent Document 1, a technique for improving the heat insulating performance of the vacuum heat insulating material was often proposed.

Japanese Patent No. 3885742

However, it is still beneficial to control the temperature in the heat insulating space formed by the vacuum heat insulating material, and in order to realize this, the above-mentioned two problems, that is, the problem of the battery life, the measurement result of the temperature sensor Need to solve the difficulty problem. The conventional technology related to the vacuum heat insulating material including Patent Document 1 cannot solve such a problem.

  An object of the present invention is to solve the above problem by providing a vacuum heat insulation panel that has an excellent heat insulation function and that can measure the ambient temperature and communicate the measured temperature.

  The present invention was made based on the idea that a temperature sensor that is not normally placed in an adiabatic environment due to the nature of temperature measurement is intentionally installed in a vacuum insulation material. This was developed for a vacuum thermal insulation panel with a sensor in which a wireless sensor having a sensor unit capable of measuring temperature was installed.

Vacuum insulation panels with the sensor of the present invention is a vacuum insulating panels covered with a gas barrier enveloping member for the core material, the temperature sensor unit that can measure the ambient temperature, the measurement result of the temperature sensor unit wireless communication A possible communication unit and a battery are installed inside the jacket material.

  In the vacuum heat insulating panel with sensor of the present invention, one part or all parts selected from the three parts of the temperature sensor part, the communication part, and the battery may be separate.

  In the vacuum heat insulating panel with sensor of the present invention, a wireless sensor having three parts of a temperature sensor unit, a communication unit, and a battery may be installed inside the jacket material.

  In the vacuum heat insulating panel with sensor of the present invention, the battery may be disposed on one surface of the plate-shaped core member, and the temperature sensor unit may be disposed on the other surface of the plate-shaped core member. .

  In the vacuum heat insulation panel with sensor of the present invention, the jacket material is formed by combining a heat conductive material and a radio wave permeable material, and the range covering the communication part of the jacket material is radio wave transmissive. It can also be a material.

[Embodiment 1]
An example of an embodiment of a vacuum heat insulating panel with a sensor according to the present invention will be described with reference to the drawings. FIGS. 1-5 is sectional drawing which shows the vacuum heat insulation panel 1 with a sensor of this invention. As shown in these drawings, the sensor-equipped vacuum heat insulation panel 1 is obtained by attaching a wireless sensor 4 to a vacuum heat insulating material provided with a core material 2 and a jacket material 3, and FIGS. The vacuum heat insulation panel 1 with a sensor from which the attachment method differs is shown.

(Production method)
A vacuum heat insulating material is pressure-reduced in the state which covered the core material 2 with the jacket material 3, and the opening part of the jacket material 3 is heat-welded (heat-sealed). A large number of gaps are provided inside the core member 2, and the air in the gaps is discharged by pushing out air or sucking air by a roller, whereby the inside of the vacuum heat insulating material is depressurized to be in a vacuum state. At this time, if the core material 2 is damp, it is difficult to maintain the subsequent vacuum state. Therefore, it is desirable to carry out the air discharging operation from the inside of the gap in a dry environment such as sending dry air. The vacuum state here is not limited to the absolute vacuum state, but refers to a state with a high degree of vacuum, and means a state with a vacuum degree of about 1 to 200 Pa, preferably about 1 to 100 Pa.

(Core material)
The more air that can be discharged from the core material 2 is, the more the pressure is reduced, that is, a vacuum heat insulating material with a higher degree of vacuum is obtained. Therefore, as the material of the core material 2, a so-called porous body having many voids inside is used, for example, a material made of urethane or powdered silica glass wool, a material made of fiber material such as ceramic fiber, rock wool, Etc. Styro homes can also be used as the core material 2, but there is an aspect that they are easily broken, so care must be taken depending on the use situation. Conversely, the glass wool used as the core material 2 has a characteristic that it is difficult to break.

(Coating material)
The jacket material 3 is a film (or plate) and needs to be formed of a material rich in gas barrier properties in order to maintain a vacuum state after decompression. Examples of the gas barrier film material include metal foils such as stainless steel, aluminum, and iron, plastic films, or laminated films of metal foil and plastic films. Of course, not only the metal foil but also a metal plate (thin plate) can be used, but in this case, since it is somewhat heavy, it is appropriately adopted depending on the purpose of use.

  The jacket material 3 using a metal material such as aluminum has a characteristic of high thermal conductivity, but also has a characteristic of easily absorbing radio waves. As will be described later, the wireless sensor 4 placed inside the vacuum heat insulating material measures the ambient temperature and can communicate the measurement result. In terms of measuring the ambient temperature, the aluminum material is used. Is suitable, but aluminum is not suitable for communication.

  On the other hand, a nylon-based material can be used as the jacket material 3, but the nylon-based material has a characteristic that it has low thermal conductivity and easily transmits radio waves. In other words, in contrast to aluminum materials, nylon-based materials are suitable for communication, but nylon-based materials are not suitable for measuring ambient temperature. In order to make the best use of both characteristics, the jacket material 3 can be formed by combining an aluminum material and a nylon material. As an example, the range close to the temperature sensor portion of the wireless sensor 4 (covering the temperature sensor portion) is made of an aluminum material having high thermal conductivity, and the range close to the antenna portion of the wireless sensor 4 (covering the temperature sensor portion) is A jacket material 3 made of a nylon material having good radio wave permeability can be used.

  The opening of the jacket 3 is heat-sealed in a state where the air in the gap of the core material 2 is discharged, that is, the inside of the vacuum heat insulating material is depressurized, thereby maintaining a high degree of vacuum. it can. Therefore, the jacket material 3 is often combined with a heat-weldable material. For example, a material obtained by superposing a PET material on the back surface (or front and back surfaces) of an aluminum foil can be used as the jacket material 3. Since the PET material is welded at about 90 ° C., the wireless sensor 4 is normally not melted up to about 200 ° C., which is preferable for the wireless sensor 4.

  In addition, the core material 2 and the jacket material 3 are not limited to those exemplified here, and materials and materials that have been conventionally used as vacuum heat insulating materials can be used.

(Insulation performance)
A vacuum heat insulating material has the heat insulation performance excellent by making the inside into a vacuum state (decompression state). Specifically, the heat conductivity of the vacuum heat insulating material is 0.002 to 0.01 w / mk, and compared with 0.02 to 0.03 w / mk of foamed polystyrene and 0.02 w / mk of air, the heat insulation thereof. It can be seen that the performance is remarkable.

(Wireless sensor)
FIG. 6 is a detailed plan view for explaining the wireless sensor 4. As shown in this figure, the wireless sensor 4 includes a main body portion 4a, an antenna portion 4b, and a battery 4c. A temperature sensor unit capable of detecting and measuring temperature is built in the front end side (upper side in FIG. 6) of the main body unit 4a, and a measurement result by the temperature sensor unit is provided on the other end side of the main body unit 4a. A communication unit (including the antenna unit 4b) is provided. In recent years, the wireless sensor 4 has been reduced in size, and has an outer dimension (length) of 2 to 4 mm. The wireless sensor 4 used in the vacuum heat insulating panel 1 with sensor of the present invention is also desirably small, but the size and shape can be arbitrarily selected as long as it can be installed inside the vacuum heat insulating material. In addition, the vacuum heat insulation panel 1 with a sensor of this invention should just be provided with three components, the main-body part 4a, the antenna part 4b, and the battery 4c, and does not need to be provided as the special wireless sensor 4. FIG. That is, the three parts of the main body part 4a, the antenna part 4b, and the battery 4c may be provided as separate parts, respectively, or the main body part 4a and the antenna part 4b are integrated and only the battery 4c is separate. For example, only one of these three components can be separated. Here, for convenience, the case where the vacuum heat insulating panel with sensor 1 includes a wireless sensor 4 (having three parts of a main body portion 4a, an antenna portion 4b, and a battery 4c) will be described.

  The battery 4c serves as a power source when the antenna unit 4b communicates information, and a lithium battery or the like is frequently used. Lithium batteries and the like are generally known to easily deteriorate in a low-temperature environment or a high-humidity environment, and the lifetime is extremely shortened. For this reason, the wireless sensor 4 is often used in an environment where the temperature is normal and the humidity is not high.

(Use in cold containers)
On the other hand, it is beneficial to manage the temperature in the heat insulating space constituted by the vacuum heat insulating panel using the vacuum heat insulating material. As a specific example of the heat insulation space, there is a cold storage container 5 that can store and deliver frozen food (refrigerated food), refrigerated food (frozen food), and the like. FIG. 7 is a cross-sectional view of the cold container 5 as viewed from the front. As shown in this figure, the cold insulation container 5 has a side wall 6 and a lid 7 formed of a vacuum heat insulating panel 1 with a sensor, and a bottom plate 8 formed of a vacuum heat insulating panel without a wireless sensor. Note that the cold storage container 5 shown in FIG. 7 has the outer surfaces of the side wall 6, the lid 7, and the bottom plate 8 reinforced with a reinforcing material 9. In the accommodation space 10 formed by being surrounded by the side wall 6, the lid 7 and the bottom plate 8, food F such as refrigerated food is accommodated, and dry ice D for cooling is also accommodated.

  By making the cold insulation container 5 have the structure shown in FIG. 7, the temperature in the accommodation space 10 (in the heat insulation space) can be further managed after the inside of the accommodation space 10 (in the heat insulation space) is thermally insulated from the outside. That is, since the battery 4c of the wireless sensor 4 installed inside the sensor-equipped vacuum insulation panel 1 is insulated from the outside, the problem of deterioration (shortening of the life) of the battery 4c due to a low temperature environment and a high humidity environment is solved. it can. Further, since the measured temperature is communicated by the antenna unit 4b of the wireless sensor 4, the temperature in the accommodation space 10 (in the heat insulating space) can be easily confirmed without opening and closing the lid 7. In addition, as shown in FIG. 7, the antenna part 4b of the vacuum heat insulation panel 1 with a sensor passes the inside of the through-hole and the through-groove provided in the core material 2, and the other side surface (in FIG. 7, the accommodation space 10 side) ). Of course, the entire antenna portion 4b can be arranged on the same surface of the core member 2 as shown in FIGS. 1 to 5 without extending the antenna portion 4b to the opposite side.

Although the radio | wireless sensor 4 used for the vacuum heat insulation panel 1 with a sensor may be produced separately as an exclusive thing, what is marketed can also be used. Further, the wireless sensor 4 which is commercially available, in addition to the temperature sensor which can measure the temperature, some of which including an acceleration sensor capable of measuring the degree of vibration. Thus, in addition to the temperature sensor, a wireless sensor 4 provided with the acceleration sensor, when employed in the vacuum with the sensor insulation panels 1, for example, in transporting the food F in cold container 5 shown in FIG. 7, the food F since vibration situations can be grasped, it is more preferable in view of quality control.

  Various methods can be selected for the method of installing the wireless sensor 4 inside the vacuum heat insulating material, and examples thereof are shown in FIGS.

  FIG. 1 is a cross-sectional view showing a case where the wireless sensor 4 is embedded in the core material 2. As shown in this figure, the wireless sensor 4 can be installed in the embedded recess 11 provided in the core material 2. Alternatively, any one of the three parts of the main body part 4a, the antenna part 4b, and the battery 4c can be installed in the embedded concave part 11, or two parts selected from these three parts can be installed in the embedded concave part 11. It can also be installed. In this case, the embedded concave portion 11 is provided in the core material 2 in advance, and the wireless sensor 4 (or at least one of the three components) is installed on the core material 2, and then the envelope material 3 is put over to reduce the pressure. The vacuum insulation panel 1 with sensor is completed by heat-sealing the opening of the material 3. The void formed in the embedded recess 11 after the wireless sensor 4 (or at least one of the three components) is installed is injected with a highly heat-conductive filler before the outer covering material 3 is covered. Or it can be left as a void. When the battery 4c is installed in the embedded recess 11, the battery 4c is disposed at the substantially central portion of the core member 2, so that it can be reliably protected from the external low temperature and high humidity environment.

  FIG. 2 is a cross-sectional view showing a case where the wireless sensor 4 is arranged on the surface of the core material 2. As shown in this figure, a wireless sensor 4 can be installed between the core material 2 and the jacket material 3. In this case, the wireless sensor 4 is attached to the surface of the core material 2 (upper surface in the figure) in advance, and then the outer cover material 3 is covered and decompressed, and the opening of the outer cover material 3 is heat-sealed, whereby a vacuum with a sensor is provided. The heat insulation panel 1 is completed. Since the main body portion 4a and the antenna portion 4b are covered only with the jacket material 3, they are preferable in terms of temperature measurement and communication. Since this sensor-equipped vacuum heat insulation panel 1 has the battery 4c near the surface, the surface where the battery 4c is not disposed (the lower surface in the figure) is a low-temperature and high-humidity environment (specifically, the storage container 5 is accommodated). It is desirable to arrange and use it so as to be on the space 10 side.

  FIG. 3 is a cross-sectional view showing a case where the main body portion 4 a and the antenna portion 4 b of the wireless sensor 4 are embedded in the surface of the core material 2 and the battery 4 c is embedded in the core material 2. In this case, the battery 4c is embedded in a part of the core material 2 in advance, the main body portion 4a and the antenna portion 4b are attached to the surface of the core material 2, and then the outer cover material 3 is covered to reduce the pressure. The vacuum insulation panel 1 with sensor is completed by heat-sealing the opening. Since the main body portion 4a and the antenna portion 4b are covered only with the jacket material 3, they are preferable in terms of temperature measurement and communication. Moreover, since the battery 4c is disposed inside the core member 2, it can be protected from an external low temperature / high humidity environment. In addition, in the vacuum insulation panel with sensor 1 of this figure, the surface (the lower surface in the figure) where the battery 4c is not disposed is a low temperature / high humidity environment (specifically, the storage space 10 side of the cold storage container 5). It is desirable to arrange and use them.

  4 shows a case where the antenna unit 4b and the battery 4c of the wireless sensor 4 are arranged on one surface of the core member 2, and the temperature sensor unit at the tip of the main body unit 4a is arranged on the other surface of the core member 2. It is sectional drawing shown. In this case, the antenna portion 4b and the battery 4c are installed on one surface (upper surface in the drawing) of the core member 2, and the temperature sensor portion at the tip of the main body portion 4a is connected to the other surface (lower surface in the drawing). The sensor-equipped vacuum heat insulation panel 1 is completed by placing the cover material 3 and then reducing the pressure by covering the cover material 3 and heat-sealing the opening of the cover material 3. In addition, the temperature sensor part in the front-end | tip of the main-body part 4a can be passed through the through-hole and through-groove provided in the core material 2, and can be extended to the surface on the opposite side.

  FIG. 5 shows a case where the antenna unit 4b and the battery 4c of the wireless sensor 4 are embedded near one surface of the core member 2 and the temperature sensor unit at the tip of the main body unit 4a is disposed on the other surface of the core member 2. FIG. In this case, the battery 4c is embedded in the vicinity of one surface (upper surface in the drawing) of the core member 2 and the antenna portion 4b is installed, and the temperature sensor portion at the tip of the main body portion 4a is connected to the other surface (see FIG. Then, the vacuum insulation panel 1 with a sensor is completed by placing the outer cover material 3 and then reducing the pressure by covering the outer cover material 3 and then heat-sealing the opening of the outer cover material 3. In addition, the temperature sensor part in the front-end | tip of the main-body part 4a can be passed through the through-hole and through-groove provided in the core material 2, and can be extended to the surface on the opposite side.

  The sensor-equipped vacuum heat insulation panel 1 shown in FIGS. 4 and 5 is preferable in terms of communication because the antenna portion 4b is covered only with the jacket material 3. Moreover, since the battery 4c is arrange | positioned on the surface (or surface vicinity) of one core material 2, and the temperature sensor part is arrange | positioned on the other core material 2 surface, for example, this temperature-insulated vacuum insulation panel 1 When a certain surface (the lower surface in FIGS. 4 and 5) is arranged and used so as to be on the side of the accommodation space 10 of the cold container 5 (FIG. 7), it is preferable in terms of temperature measurement, and the battery 4c is used at a low temperature and high humidity. It is also suitable in terms of protection from the environment.

  When temperature measurement by the temperature sensor unit and communication by the antenna unit 4b are considered, selection of the material of the jacket material 3 used near the temperature sensor unit and the antenna unit 4b at the tip of the main body unit 4a is important. As described above, metal materials such as aluminum have a high thermal conductivity, while they easily absorb radio waves. On the other hand, nylon materials have a low thermal conductivity and do not emit radio waves. It has the characteristic of being easily transmissive. Therefore, in the case of the sensor-equipped vacuum heat insulation panel 1 shown in FIGS. 4 and 5, the surface on which the antenna portion 4b is arranged (the upper surface in the figure) is made of a radio wave permeable nylon material, and the surface on which the temperature sensor portion is arranged. It is desirable to make the outer cover material 3 using a metal material having high thermal conductivity (the lower surface in the figure).

  In the case of the vacuum heat insulating panel 1 with a sensor shown in FIGS. 1 to 5, the entire material is made of a metal material having high thermal conductivity, and a nylon-based material that is partially permeable to radio waves is used only in a range that covers the antenna portion 4b. The jacket material 3 can also be used. Alternatively, the entire material may be a radio wave-transmitting nylon material, and the outer covering material 3 may be made of a metal material having a high thermal conductivity partially within a range covering the temperature sensor portion. If the material is partially different (the entire material is made of metal and partly nylon material, or vice versa), a different material part may be provided so as to form a hole or groove including the part. it can.

  The vacuum heat insulating panel with sensor of the present invention can be applied as a building material such as a flooring material or an outer wall material.
