Remote controlled heat sink attached to wall

A remote controlled heat sink attached to a wall comprises a cooling block attached to the wall, a circuit board required for cooling, heat conduction posts, an iron sheet, an installation rack, an electromagnet, a relay and an infrared remote control switch, wherein the heat conduction posts are used for fixing the circuit board required for cooling and the cooling block attached to the wall, the relay is used for controlling the opening and closing of the electromagnet, the infrared remote control switch is used for controlling the action of the relay, the two sides of the iron sheet are respectively connected with struts and cylinders, the other ends of the struts are fixedly connected with the cooling block attached to the wall, the other ends of the cylinders and the installation rack are movably connected, and the electromagnet is fixedly arranged at the bottom of the installation support. The remote controlled heat sink attached to the wall is convenient to install, can be adaptive to cavities at different sizes, and can be installed at arbitrary depths of the cavities, the installation and the disassembly of each module in the cavity are not affected, and the remote controlled heat sink can be effectively attached onto the wall for cooling.
