Embodiment approach 1
[0071] figure 1 It is a plan view of the fiber heat insulating body of Embodiment 1 of this invention. figure 2 yes means figure 1 Sectional view of the 2-2 line section. image 3 yes means figure 1 Sectional view of the 3-3 line section. Figure 4 It is a cross-sectional view of a vacuum heat insulator using the fiber heat insulator of this embodiment as a core material.
[0072] Such as Figure 1 ~ Figure 3 As shown, the fiber heat insulating body 6 includes: a fiber body 8 having two opposite heat transfer surfaces 7; The line 5 of the compressed state of the body 8. The wire 5 has a portion 5 a exposed on one heat transfer surface 7 and a portion 5 a exposed on the other heat transfer surface 7 . In addition, the threads 5 are exposed on the heat transfer surface 7 parallel to the longitudinal direction of the fiber body 8 . In addition, in figure 1 In , the portion of the line 5 exposed to the heat transfer surface 7 is indicated by oblique lines. Such as ...
Embodiment approach 2
[0087] The fiber heat insulator according to Embodiment 2 of the present invention is different from Embodiment 1 in that the compressed state of the fiber heat insulator is restricted by interlacing and intertwining two threads. In addition, since the plan view of a fiber heat insulating body is the same as that of Embodiment 1, using figure 1 Be explained. Figure 5 is along figure 1 The cross-sectional view which cut the fiber heat insulating body of Embodiment 2 of this invention along the line 2-2 of . Figure 6 is along figure 1 A cross-sectional view of the fiber heat insulating body of this embodiment cut along line 3-3.
[0088] Such as Figure 5 and Figure 6 As shown, the fiber heat insulator 6 is sewn by using the first thread 14 and the second thread 15 in the manner of lock stitch. The fiber heat insulating body 6 is comprised so that the fiber body 8 may be restrained by the interweaving of the 1st wire 14 and the 2nd wire 15. As shown in FIG. Among th...
Embodiment approach 3
[0098] In the fiber heat insulating body of Embodiment 3 of this invention, the position of an intertwined part differs from Embodiment 2. As shown in FIG. In addition, since the plan view of a fiber heat insulating body is the same as that of Embodiment 1, using figure 1 Be explained. Figure 8 is along figure 1 The cross-sectional view which cut|disconnected the fiber heat insulating body of Embodiment 3 of this invention along the 2-2 line. Figure 9 is along figure 1 A cross-sectional view of the fiber heat insulating body of this embodiment cut along line 3-3.
[0099] Such as Figure 8 and Figure 9 As shown, the fiber heat insulation body 6 is sewn by using the first thread 14 and the second thread 15 in the manner of multi-thread chain stitch. The fiber heat insulating body 6 is comprised so that the fiber body 8 may be restrained by the interweaving of the 1st wire 14 and the 2nd wire 15. As shown in FIG. Among them, the first wire 14 has: a portion 14a expo...
