The use scenario of the vacuum insulation panel 100 is shown in fig. 5, wherein a first profile 503, a second profile 504, a first insulation strip 501 and a second insulation strip 502 together enclose a cavity, and a slot 505 matching with the anchor head 101 of the vacuum insulation panel 100 is arranged on the surface of the first insulation strip 501 opposite to the second insulation strip 502. The slots 505 protrude from the insulating strips so that the shear strength of the insulating strips is not impaired. The vacuum heat insulation insert 100 is inserted into the insertion groove 505 and divides the cavity into a first sub-cavity 506 and a second sub-cavity 507 which are not communicated with each other, so that heat transfer caused by air flow can be effectively reduced.

During installation, the vacuum insulation insert 100 is inserted between the first insulation bar 501 and the second insulation bar 502 along the longitudinal direction to ensure that the anchor head 101 is inserted into the slot 505. And vacuumizing the vacuum cavity 102 from two ends of the vacuum heat insulation inserting piece 100, and heat-sealing two ends of the vacuum heat insulation inserting piece 100 after vacuumizing, wherein the vacuumizing and heat-sealing process is the prior art, and is not described again.

Preferably, before the vacuum heat insulation insert 100 is inserted, an adhesive can be sprayed on the anchor head 101 or in the slot 505, so that the gap can be blocked after insertion, and better air tightness can be obtained.

In addition, hooks may be further disposed at two ends of the vacuum insulation insert 100, as shown in fig. 11, the hook 103 is inserted into an end portion of the vacuum insulation insert 100, and two ends of the hook 103 hook ends of the first profile 503 and the second profile 504, so as to provide a supporting force for the upper and lower sidewalls of the vacuum chamber 102.

Example two:

as shown in fig. 2, the embodiment of the present invention discloses a vacuum heat insulation insert 200, wherein the sidewall of the vacuum chamber 202 is a film, so as to have a certain flexibility, the film can be made of plastic (such as polycarbonate, polyethylene, polyvinyl chloride, polystyrene, polyester, polypropylene, etc.) or rubber material, and the anchor head 201 can be made of rigid plastic or rubber. The upper corner and the lower corner of two sides of the vacuum heat insulation insert sheet 200 are provided with anchor heads 201, so that the anchor heads 201 at the corners can pull the film, and the film is prevented from contacting with each other to form a heat bridge. In addition, in order to prevent the side walls of the vacuum chamber 202 from contacting each other by suction, a support 203 may be further provided in the vacuum chamber 202. The supporting members 203 may be uniformly spaced along the length direction of the vacuum insulation panel 200 at equal intervals, or may be formed in a sheet shape along the length direction. The supporting member 203 may also be made of hard plastic or rubber, and both ends of the supporting member are fixedly connected to the sidewalls of the vacuum insulation insert 200.

Example three:

as shown in fig. 3, the embodiment of the present invention discloses a vacuum thermal insulation insert 300, which has the same main structure as the embodiment, except that a connecting member 304 is disposed on the sidewall of the vacuum thermal insulation insert to replace the supporting member 203 of the embodiment. The connector 304 is pulled against the side walls of the cavity, thereby also ensuring that the side walls of the vacuum chamber do not touch each other.

As shown in fig. 6, the vacuum insulation insert 300 is disposed in a cavity defined by a first profile 601, a second profile 602, a first insulation strip 603, and a second insulation strip 604, and a slot 605 corresponding to an anchor head is disposed on a surface of the first insulation strip 603 facing the second insulation strip 604. A pull 304 is pulled between the sidewall of the vacuum insulation panel 300 and the second profile 602. The side wall of the second profile 602 is provided with a sealing edge 606 for connecting with the end of the pulling element 304.

When the vacuum heat insulation insert 300 is installed, the vacuum heat insulation insert 300 is inserted between the heat insulation strips, the end of the pull-connecting piece 304 is clamped into the sealed edge 606, and then the vacuum cavity is vacuumized from two ends of the vacuum heat insulation insert 300 and then is subjected to heat sealing.

The above embodiments show the situation that the vacuum heat insulation insert is applied in the cavity formed between different profiles, but the cavity formed in the same profile also has the problem of air flow and heat transfer, especially the cavity adjacent to the connection part of the heat insulation strip. The following examples show the situation of inserting vacuum heat insulation inserts into the cavity of the same profile.

Example four:

as shown in fig. 7, the embodiment of the present invention discloses a vacuum thermal insulation insert 700, wherein an anchor head 702 is disposed on the same side surface, so as to be connected to the same side wall of the cavity.

As shown in fig. 8, the vacuum insulation insert 700 is installed in a cavity inside a first profile 701, a first insulation strip 703 and a second insulation strip 704 are connected below the cavity, a heat transfer path in the first profile 701 is mainly a heat transfer path a in a side wall and a heat transfer path b in the cavity, and the vacuum insulation insert 700 is mainly used for blocking the heat transfer path b.

Specifically, anchor head 702 of vacuum insulation insert 700 is inserted into slot 706 in sidewall 705. Preferably, the insertion position of the anchor head 702 is located at the opposite side of the first heat insulation strip 703 and the second heat insulation strip 704, so that the heat in the air can only be transferred along the heat conduction path c, and the heat insulation effect is better. If the anchor head 702 is misaligned with the insulating strips, there may be other heat conduction paths that affect the insulating effect.

Example five:

as shown in fig. 4 and 9, the other parts are the same as those of the fourth embodiment, and it is different from the fourth embodiment in that the side wall of the vacuum insulation insert sheet 800 is made of a film, and a pulling member 801 is pulled between the vacuum insulation insert sheet 800 and the first profile 802 to ensure that the side walls of the vacuum chambers do not contact each other, and the connection structure thereof can refer to the third embodiment.

Example six:

as shown in fig. 10, the other parts are the same as those of the fifth embodiment, and the difference is that the anchor head 901 of the vacuum insulation insert sheet 900 is a combination of two anchor heads 803 of the fifth embodiment, so that the insertion installation is more convenient.

To sum up, the embodiment of the utility model provides a vacuum heat insulation inserted sheet separates into the two parts that do not communicate each other with the cavity in the section bar, and the effectual heat transfer that causes because of the air current that has reduced. Meanwhile, the vacuum cavity is arranged in the vacuum heat insulation insert, so that a transmission path of internal and external heat through air is blocked, and the overall heat transfer coefficient of the cavity is further reduced. In addition, the inserting piece structure can meet the sealing requirement of the vacuum cavity, and the installation is also convenient.
