A heat dissipation apparatus is provided, an electronic component is disposed on one side of an adjustable heat dissipation component, and a rotating shaft is disposed on another side of the adjustable heat dissipation component; and one end of a connecting component is connected to the adjustable heat dissipation component, another end of the connecting component is connected to a fixed substrate, and the connecting component drives the adjustable heat dissipation component to rotate by using the rotating shaft. The connecting component may be adjusted to rotate the electronic component together with the adjustable heat dissipation component, to reduce complexity in deploying the electronic component and the heat dissipation apparatus without affecting a heat dissipation effect, thereby improving convenience of operation.

Heat dissipation apparatus, heat dissipator, electronic device, and heat dissipation control method

A tunable filter includes a first waveguide body, a second waveguide body, a metal plate, a tuning piece, and a driving piece. A first cavity is disposed in the first waveguide body, and a second cavity is disposed in the second waveguide body. The metal plate is sandwiched between the first waveguide body and the second waveguide body, multiple windows are disposed on the metal plate, and the first cavity and the second cavity are in communication and are symmetrically distributed on both sides of the metal plate. The tuning piece includes a dielectric pull-rod and multiple metal sheets connected to the dielectric pull-rod, the dielectric pull-rod protrudes out of the first waveguide body and is connected to the driving piece, the multiple metal sheets are disposed inside the first cavity, and the multiple metal sheets are disposed corresponding to the multiple windows.
