1. Heat well possessing means for ensuring a controlled dissipation of the heat coming from an experimentation tube (44) arranged in a metal block (40) to a cooling liquid circulating in a coil (46) arranged in the metal block (40), this well being characterized in that it has a layer of alloyed metal (84), this metal being selected to be liquid at the operating temperature of the well and solid at the ambient temperature, this layer (84) being interposed between the experimentation tube (44) and the metal block (40), and this layer (84) thus ensuring, when it is liquid, a good heat transfer between the experimentation tube (46) and the metal block (40) during the operation of the well and, when it is solid, a good mechanical retention of the experimentation tube (46) in the metal block (40) before the well is put into operation, in that it has a liquid (47) between the coil (46) and the metal block (40), this liquid ensuring close thermal contact between the block (40) and the coil (46), and in that it possesses regulating members acting on the flow of cooling fluid circulating in the coil (46) as a function of the temperature of the well, these members being designed to increase this flow when the temperature of the well increases and to reduce this flow when the temperature of the well decreases. |
