Technical Field

[0001] The utility model relates to the technical field of Mylar sheets, in particular to a shielded heat dissipation type Mylar sheet. Background Art

[0002] Mylar sheet is a common sheet material used for packaging electronic components. It is generally made of polyester film and comes in a variety of colors, including milky white, black, natural color, and transparent. In terms of material, there are PET Mylar sheet, PVC Mylar sheet, PC Mylar sheet, etc.

[0003] The common Mylar sheets currently on the market are mostly similar in structure. They are generally single-layer structures and are prepared using a shrinkage and stretching process. They need to be glued together during installation. There are some functional deficiencies in actual use and there is room for improvement. Taking Mylar sheets made of PET polyester film as an example, they have good heat resistance, but poor heat dissipation capacity, and are insufficient in shielding external signals. Some styles will add bent copper wires inside for shielding, but the bending and addition of copper wires increase the difficulty of the process, and the shielding effect is not ideal, prone to omissions, and does not have the function of shielding interference or helping heat dissipation.

[0004] Now, a new type of shielded heat dissipation Mylar sheet is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a shielding heat dissipation type Mylar sheet to solve the problem in the above background technology that the sheet does not have the function of shielding interference and facilitating heat dissipation.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a shielded heat-dissipating Mylar sheet, comprising a PET substrate, a first reserved groove being provided at the top of one side of the rear end of the PET substrate, a second reserved groove being provided at the bottom of the other side of the rear end of the PET substrate, and a shielding component being provided at the front end of the PET substrate for shielding interference and facilitating heat dissipation.

[0007] The shielding assembly includes a copper foil shielding layer, which is fixedly connected to the front end of the PET substrate. Multiple groups of fin slots are arranged inside the middle position of the PET substrate. Multiple groups of heat dissipation fins are welded to the rear end of the copper foil shielding layer, and a plastic insulation layer is glued to the front end of the copper foil shielding layer.

[0008] Preferably, the PET substrate and the copper foil shielding layer have the same shape, and the edges of the PET substrate and the copper foil shielding layer are aligned.

[0009] Preferably, the shapes and sizes of the fin slots and the heat dissipating fins are the same, and the positions of the fin slots and the heat dissipating fins correspond one to one.

[0010] Preferably, the heat dissipation fins penetrate the interior of the fin slots and extend to the outside, and the copper foil shielding layer and the heat dissipation fins are made of the same material.

[0011] Preferably, the four corners of the rear end of the PET substrate are respectively fixedly connected with outer wall connecting feet, and the rear ends of the outer wall connecting feet are evenly coated with self-adhesive stickers.

[0012] Preferably, the outer wall connecting legs are symmetrically distributed about the vertical center line of the PET substrate, and the rear end surface of the self-adhesive sticker is applied with release paper.

[0013] Preferably, a first latex inner lining ring is glued to the interior of the second reserved groove, and a second latex inner lining ring is glued to the interior of the first reserved groove.

[0014] Preferably, the outer walls of the first latex inner lining ring and the second latex inner lining ring are respectively connected to the inner walls of the second reserved groove and the first reserved groove, and the first latex inner lining ring and the second latex inner lining ring are elastic.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the shielding heat dissipation type Mylar sheet not only realizes the function of shielding interference and helping heat dissipation, but also realizes the function of easy disassembly and assembly, and also realizes the function of pre-fixation and anti-falling;

[0016] (1) By providing a fin slot, a copper foil shielding layer, a heat dissipation fin and a plastic insulating layer, when in use, the PET substrate is used as the base material of the Mylar sheet and is attached to the inner wall of the device shell to encapsulate the internal electronic components. The copper foil shielding layer faces the side of the electronic components to shield external signal interference. The plastic insulating layer can prevent the copper foil shielding layer from directly contacting the electronic components. When the electronic components are working and generating heat, the copper foil shielding layer with good thermal conductivity can quickly absorb the heat and conduct it outward through the heat dissipation fins. The fin slot reserves space for the passage of the heat dissipation fins, thereby achieving the function of shielding interference and helping heat dissipation.

[0017] (2) By providing an outer wall connecting foot, a self-adhesive sticker and a release paper, before installing the Mylar sheet, first tear off the release paper on the surface of the self-adhesive sticker, then face the side where the outer wall connecting foot is located toward the inner wall of the device housing, and press it tightly.

A plurality of fin slots 3 are provided inside the middle position of the PET substrate 1. A plurality of heat dissipation fins 5 are welded to the rear end of the copper foil shielding layer 4, and a plastic insulation layer 6 is glued to the front end of the copper foil shielding layer 4.

[0027] The PET substrate 1 and the copper foil shielding layer 4 have the same shape, the edges of the PET substrate 1 and the copper foil shielding layer 4 are aligned, the fin slots 3 and the heat dissipating fins 5 have the same shape and size, the positions of the fin slots 3 and the heat dissipating fins 5 correspond one to one, the heat dissipating fins 5 pass through the interior of the fin slots 3 and extend to the outside, and the copper foil shielding layer 4 and the heat dissipating fins 5 are made of the same material, which can shield interference while improving heat dissipation capacity;

[0028] Specifically, if Figure 1 and Figure 4 As shown, the copper foil shielding layer 4 faces the side of the electronic component, which plays a role in shielding external signal interference. The plastic insulation layer 6 can prevent the copper foil shielding layer 4 from directly contacting the electronic component. When the electronic component is working and generating heat, the copper foil shielding layer 4 with good thermal conductivity can quickly absorb the heat and conduct it outward through the heat dissipation fins 5.

[0029] Example 2: The four corners of the rear end of the PET substrate 1 are respectively fixedly connected to the outer wall connecting legs 7. The rear ends of the outer wall connecting legs 7 are evenly coated with self-adhesive stickers 8. The outer wall connecting legs 7 are symmetrically distributed about the vertical center line of the PET substrate 1. The rear end surface of the self-adhesive stickers 8 is applied with release paper 9. Installation and removal are relatively convenient, and no additional gluing process is required;

[0030] Specifically, if Figure 2 and Figure 3 As shown, tear off the release paper 9 on the surface of the sticker 8, then face the side of the outer wall connecting foot 7 toward the inner wall of the device housing, press tightly, and the sticker 8 will stick to the inner wall of the device housing.

The PET substrate 1 serves as the base material of the Mylar sheet and is attached to the inner wall of the device casing to encapsulate the internal electronic components. The copper foil shielding layer 4 faces the side of the electronic components to shield external signal interference. The plastic insulating layer 6 can prevent the copper foil shielding layer 4 from directly contacting the electronic components. When the electronic components generate heat during operation, the copper foil shielding layer 4 with good thermal conductivity can quickly absorb the heat and conduct it outward through the heat dissipation fins 5.
