Between the sun, machines, computers and body heat, how isn’t everything we send to space cooking itself to death?

Things like the Voyager Probe is far away from the sun and can radiate what little heat energy it has. (Gasses between stars are around -455 °F) The James Webb Space Telescope is closer to Earth (and the Sun) so it was built with a solar shield that looks like a shiny umbrella so that it can reflect most of the sun’s energy and keep the telescope in the shade. It also has a cryocooler to conduct heat away from the instruments and then radiate the heat into space. (Gasses at this distance are about 45 °F)
Side note: ‘the vacuum of space’ is referring to how little gas is present: about one hydrogen atom per cubic meter- not really related to vacuum cleaners which is a machine that is like a mechanical drinking straw
