Detailed Description

The present utility model will be described in further detail with reference to the drawings and the detailed description below, in order to make the objects, technical solutions and advantages of the present utility model more clear and distinct. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present utility model are shown in the accompanying drawings.

The embodiment provides a vehicle-mounted refrigerator heat preservation structure, as shown in fig. 1, the vehicle-mounted refrigerator heat preservation structure comprises a box body 1 and an inner container 2 arranged in the box body 1, wherein a bulge part 3 is arranged on the inner wall of the box body 1, one side of a vacuum heat insulation plate 4 is tightly attached to the surface of the bulge part 3 for fixation, a gap 5 is reserved between the inner container 2 and the vacuum heat insulation plate 4, and heat preservation foam is filled between the box body 1 and the inner container 2.

In this embodiment, the bulge 3 is disposed on the inner wall of the box 1, so that the vacuum insulation board 4 is not in direct contact with the box 1, meanwhile, a gap 5 is left between the inner container 2 and the vacuum insulation board 4, so that the vacuum insulation board 4 is not in direct contact with the inner container 2, and finally, heat preservation foam is filled between the box 1 and the inner container 2, so that the vacuum insulation board 4 is suspended between the box 1 and the inner container 2, and the heat preservation effect of heat preservation of the refrigerator is enhanced.

It is known that the above-mentioned thermal insulation structure of the vehicle-mounted refrigerator needs to be fixed by a mold and injected with foaming materials. Specifically, firstly, the liner 2 is reversely buckled and placed into a corresponding model to be fixed, then the vacuum insulation panel 4 is placed on the outer side and the outer bottom of the liner 2, after the box body 1 is reversely buckled, the inner space of the box body 1 is used for covering the whole liner 2 and the vacuum insulation panel 4, the box body 1 is fixed by using another die, so that a gap 5 is reserved, finally, heat preservation foam is injected through a material injection hole (not shown in the figure) at the bottom of the box body 1, all the space between the box body 1 and the liner 2 is filled through heat preservation foam foaming, and meanwhile, the vacuum insulation panel 4 is buried into the heat preservation foam to be fixed. The above steps of fixing the mold and injecting the glue are conventional techniques, and will not be discussed further. Of course, point-shaped thermal insulation foam may be injected between the inner container 2 and the vacuum insulation panel 4 in advance, and the inner container 2 and the vacuum insulation panel 4 may be primarily fixed by using the thermal insulation foam, so that a gap 5 is formed between the vacuum insulation panel 4 and the inner container 2, and no direct contact is formed between them.

In a preferred embodiment, the raised portion 3 is integrally formed with the case 1, for example, by reverse molding, and the raised portion 3 is integrally formed on the inner wall of the case 1, thereby improving the strength of the raised portion 3 and saving the installation time.

The raised portion 3 may be any protrusion, such as a dot-like protrusion or a stripe-like protrusion. As shown in fig. 2, it conceals the liner 2 and one of the vacuum insulation panels 4 to expose the bulge 3. In one example, the ridge 3 includes a grating 301, and a grating array 302 directly coupled to the grating 301, the grating 301 being disposed at an inner bottom of the case 1, and the grating array 302 being disposed at inner side walls (four sides) of the case 1. Referring to fig. 2, one or several pieces of vacuum insulation panels 4 are horizontally placed on the surface of a grid 301, one or several pieces of vacuum insulation panels 4 are vertically and tightly placed on the surface of a grid array 302, a certain supporting space can be provided for the vacuum insulation panels 4 through the design of the grid 301 and the grid array 302, the vacuum insulation panels 4 are prevented from being directly contacted with the inner wall of a box body 1, and after thermal insulation foam is injected, the foam expands to fill the space in the grid 301 and the grid array 302, so that the thermal insulation effect and the fixing effect are achieved.

More preferably, the height of the protrusions of the grid 301 and the grid array 302 is 1-1.5cm, under the scheme, the distance between the vacuum insulation panel 4 and the inner wall of the box body 1 is proper, after the heat insulation foam is injected, the cooling capacity of the liner needs to penetrate through two layers of heat insulation foam and one layer of vacuum insulation panel 4 to reach the surface of the box body 1, and the height of the protrusions effectively avoids that the grid 301 and the grid array 302 excessively occupy the space of the liner 2, so that the size of the liner 2 is too small.

With continued reference to fig. 2, in this embodiment, the grid array 302 may be arranged along the width direction of the inner sidewall of the box 1, and in this embodiment, the arrangement mode of the grid array 302 mainly plays a role of a reinforcing rib, which increases the compressive strength of the box 1, so as to protect the vacuum insulation panel 4.

The primary purpose of the ridge of the array of bars 302 in this embodiment is to support the vacuum insulation panel 4 in position, and optionally the height of the array of bars 302 is at least one quarter of the height of the enclosure 1, as described above. The present solution has been described that the thermal insulation foam is injected between the box 1 and the liner 2 through the injecting hole at the bottom of the box 1, so that the vertical uniform portion of the grid in the grid array 302 also plays a role in guiding flow, so that the filled thermal insulation foam (such as PU foam) flows more uniformly along the grid array 302 to the space between the vacuum insulation panel 4 and the box 1 and the liner 2, thereby effectively fixing and increasing the thermal insulation effect.

Since the vacuum insulation panel 4 is a wearing part, it expands immediately upon breakage, resulting in expansion and deformation of the case 1. Therefore, in a preferred embodiment, the grid array 302 includes a plurality of grids, and the top end of each grid is rounded/chamfered, so as to effectively reduce the occurrence of breakage of the vacuum insulation panel 4.

Optionally, the thermal insulation foam may be polyurethane self-foaming material.

The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same, and are not intended to limit the scope of the present utility model. All equivalent changes or modifications made in accordance with the essence of the present utility model are intended to be included within the scope of the present utility model.
