Embodiment approach 1

[0056] figure 1 (a) shows the cross-sectional view of the heat insulating material 101 in Embodiment 1. figure 1 (b) shows the perspective view of the heat insulating material 101 in Embodiment 1. also, figure 2 A structural model representing an airgel used in thermal insulation.

[0057] The heat insulating material 101 includes: a block 102 of airgel, an air layer 103, and a resin film 104 covering these parts. As an example, a cuboid heat insulating material is shown.

[0058]

[0059] The size is defined by assuming a cuboid (the smallest cuboid included) covered by contacting each particle. The maximum particle diameter is the length of the longest side among the three sides of the cuboid. The average particle diameter is a diameter obtained by averaging the average values ​​of the three sides of each particle. The following dimensions are defined the same.

[0060] Since the block 102 of airgel needs to be tightly packed in the heat insulating material 101, ...

Embodiment 1

[0082] As Example 1, a heat insulating material 101 ( figure 1 (b)). The block 102 of airgel is enclosed by a resin film 104 . replace Figure 10 The liner 7 of the vending machine shown in (a), (b) is used. That is to say, the heat insulating material 101 is attached to the partition board main body 2 (made of foamed polyurethane), and the heat insulating material 101 is filled with blocks of airgel blocks 102 with an average particle diameter of 10 mm into the blocks made of PE. made of bags.

[0083] If the separator main body 2 with the heat insulating material 101 is as Figure 10 (b) When used in this way, compared with the conventional material, since thermal conductivity is low, it turns out that heat leakage from a gap can be suppressed. The thermal conductivity is 0.02 W / m·K. Furthermore, since it has compression performance, it is also possible to prevent heat leakage.

[0084] In Embodiment 1, regarding the air layer 103 present in the airgel block 102 stuffe...

Embodiment approach 2

[0086] Embodiment 2 is characterized in that the resin film 104 described in Embodiment 1 is provided with a heat-shrinkable function.

[0087] As the heat-shrinkable resin, a heat-shrinkable resin to which the shape memory effect of plastic by electron beam irradiation is applied is used. "Sumiturub" and "Iracustribu" (trademark) manufactured by Sumitomo Electric Industries can be used.

[0088] As the material, polyolefin, polyvinylidene fluoride as a fluoropolymer, thermoplastic elastomer, etc. are selected, but the resin is not limited to these as long as it has shrinkability.

[0089] These resins are characterized in that, when exposed to a temperature of, for example, 100°C, they shrink to about half in a certain direction at the maximum, and the film can increase in thickness direction to reduce the volume of the bag. The thickness and the like of the resin film 104 are the same as those in the first embodiment.

[0090] As mentioned earlier, aerogels are structurall...

Abstract

The invention provides a thermal insulation material and electronic equipment using the same and aims to solve heat conduction loss during cooling and heating of the internal of two warehouses spaced by a separator plate. The invention relates to a thermal insulation material which reduces heat conduction loss and a spacing thermal insulation material of electronic equipment using the same thermal insulation material. By using a thermal insulation material provided with aerogel as a nanometer porous body of silicon dioxide in an enclosure manner, the thermal insulation material which can be buried in a complex form is provided, so that heat movement with air around the separator plate as a thermal medium is inhibited, and the energy saving performance of electronic equipment such as a vending machine and a refrigerator is improved.

Description

technical field [0001] The present invention relates to a heat insulating material used in vending machines, refrigerators, heating furnaces and the like. Background technique [0002] Conventionally, in an automatic vending machine, the area|region of the high temperature part of a product and a cooling part is formed by the partition plate of the heat insulation wall which partitions a store|warehouse. As the structure of the partition plate, there is a structure in which the partition plate is bordered by an L-shaped steel plate member (Patent Documents 1 and 2). [0003] Figure 10 (a) is an exploded perspective view showing the partition plate 1 of the conventional vending machine described in Patent Document 1. FIG. It includes a partition board main body 2 , an upper frame 3 , a rear frame 5 , a lower frame 4 , a front frame 6 and a liner 7 . [0004] The partition panel 1 is composed of a partition panel main body 2 made of rigid polyurethane foam, an upper frame 3...
