Heat dissipation components, signal transmission devices and electronic equipment

Abstract

This invention provides a heat dissipation assembly, a signal transmission device, and an electronic device. The housing has an outlet and an inlet communicating with a heat exchange chamber to facilitate the circulation of the heat exchange fluid. Therefore, on the one hand, when the heat source element comes into contact with the contact area, the elastic deformation generated by the deformation zone ensures stable heat conduction between the contact area and the heat source element. When the heat source element separates from the contact area, the contact area can also promptly reset under the action of the deformation zone. On the other hand, raising the height of the housing using two support columns facilitates the assembly of the heat dissipation assembly with connecting devices, making it easier to bring the heat source element and the contact area into contact. Furthermore, placing the heat exchange chamber within the housing simplifies the structure of the heat dissipation assembly and reduces manufacturing costs.
