Contrary to popular belief, space in the vicinity of Earth's orbit is not cold. Indeed, it's very hot. You get the full unfiltered force of sunlight (hotter than noon on the equator), and you don't have any material available nearby like air or water to convect the heat away. Cooling is actually a huge problem in orbit, way harder than on Earth where you can just use fans.
