The invention relates in the main claim to a heat pipe in the shape of a flat plate and, in the subclaims, to cooling bodies using said heat pipe. The heat pipe has the function of absorbing heat at an arbitrary place on the surface thereof and distributing said heat over the whole surface. This is achieved with the aid of a liquid transport medium (for example, water). The heat pipe comprises a vacuum chamber in the interior into which the water is poured. If the heat pipe is heated at an arbitrary place, the water evaporates there. The vapor condenses in the remaining colder region of the heat pipe and thus heats said region. The condensed water flows back to the heat source through capillary force and evaporates again. Due to said cycle, much more heat can be transported within the heat pipe than through a comparable massive metal plate, for example, copper. The heat transport is thus achieved in a substantially more rapid fashion than in massive copper and the temperature remains constant over the whole surface. Thus, flat heat pipes are ideal as base plates in cooling bodies and heat exchangers as they optimize the heat input into the cooling ribs. |
