Abstract
This invention relates to a shelter for thermally conditioning in particular electronic appliances which generate heat. The shelter comprises a closed box-like structure with thermoinsulating walls which houses the appliance to be conditioned, as well as a heat accumulator in the form of a fluid mass in heat exchange conditions with the structure inner environment. The heat accumulator is connected with a heat exchanger provided outside the box-like structure in such a manner that a fluid circulation, preferably a thermosiphon circulation, is established only when the fluid temperature within the heat exchanger is lower than that within the heat accumulator.
Claims5
A self-contained shelter providing a thermally conditioned environment in a well defined temperature range for an apparatus, said shelter comprising:
- a closed box having a ceiling, a floor and thermoinsulating walls defining an internal environment for housing the apparatus;
- at least one heat accumulator means for taking up heat within the internal environment, said heat accumulator means containing a heat transfer liquid in heat exchange relationship with the internal environment of the box;
- at least one heat exchanger means for circulating the heat transfer liquid from the heat exchange relationship with the internal environment to a heat exchange relationship with an external environment outside of the box;
- said heat exchanger means being located in a position higher than that of said heat accumulator means and connected thereto by a single closed heat transfer loop for allowing a thermosiphon circulation of the liquid contained in said accumulator means to the heat exchanger means only when the fluid temperature within said heat exchanger means is lower than that within said heat accumulator means;
- said heat accumulator means extending vertically from the ceiling to the floor of the box so as to provide a water head as high as possible between said heat accumulator means and said heat exchanger means in order to enhance the circulation speed of said heat transfer liquid;
- and
- said heat exchanger means is connected to an expansion tank.
