  • Publication number: 20240098879
    Abstract: This disclosure discloses a power adapter and an electronic device system, and relates to the field of heat dissipation technologies. The power adapter includes a housing, a printed circuit board assembly, and insulation powder filled in the housing. The printed circuit board assembly is fastened in the housing, and the insulation powder is used to conduct heat generated by the printed circuit board assembly to the housing. Compared with a thermally conductive adhesive, the insulation powder does not have a problem of poor fluidity, and can more easily be sufficiently filled. This solution improves heat dissipation effect of the power adapter and helps further increase a charging power of the power adapter.

  • Publication number: 20220387341
    Abstract: A pressure-sensitive adhesive matrix and a patch are disclosed. The pressure-sensitive adhesive matrix includes the following components: in parts by mass, 60-85 parts of an acrylate pressure-sensitive adhesive, 1-20 parts of a polyol, and 5-30 parts of a plasticizer. The pressure-sensitive adhesive matrix has a micro-phase separation structure, and fine polyol droplets are uniformly dispersed in a homogeneous phase structure compounded by the acrylate pressure-sensitive adhesive and plasticizer. The pressure-sensitive adhesive matrix exhibits water absorbability and moisture retention ability, so that the adhesion between the matrix and skin is not adversely influenced by TEWL. The adhesion of the matrix is gradually improved after absorbing water, therefore the adhesion time is increased.
