A patent search found that the publication number is: CN105377004A, which discloses a heat sink, including a heat sink body and multiple heat-conducting fins. The heat-conducting fins have a fin bottom end and a fin top end. The fin bottom end is located on the front of the heat sink body and is integrally formed with the heat sink body. There is a groove between multiple adjacent fin bottom ends in the longitudinal direction, and there is a groove between multiple adjacent grooves in the transverse direction. An adhesive is provided on the back of the heat sink body. The heat sink provided by the present invention is installed on the heat sink body by integrally forming multiple heat-conducting fins. Heat is transferred to the heat-conducting fins through the heat sink body. The structure is simple and practical.

At the same time, the installation size cannot be adjusted, and it cannot meet the installation requirements on humidifiers of different models, resulting in a large number of heat sink models and increased production costs. In order to solve the above problems, a heat sink structure is proposed in this application. Utility Model Content
