Cooling system by contact

Abstract

A cooling system which comprises a cooling fluid to cool a body or object, and at least a cold transmission surface in direct or indirect contact with said body or object. It is characterized in that it comprises at least a device for collecting and storing frigories that can receive a preset quantity of cooling fluid from an external charging device, store said frigories and transmit them at a preset velocity and temperature to said cold transmission surface. It is obtained a system in which it is not necessary to use a cryogenic deposit forming part of it, so that the security is enhanced and the cost is reduced. Further, the invention comprises a device ( 3 ) for absorbing heat that comprises a thermally isolated container ( 8 ), with the exception of a cold transmission surface ( 9 ) in direct or indirect contact with the body or object to be cooled, said container ( 8 ) comprising a radiator ( 10 ) that can receive a preset quantity of said cryogenic cooling fluid from an external charging device, and in that said container ( 8 ) also comprises a material around the radiator ( 10 ), filling the volume of the container ( 8 ) not occupied by the radiator ( 10 ), said material having a thermal conductivity suitable of storing the negative calories (frigories) transferred by contact from said radiator ( 10 ), and for transmitting said negative calories (frigories) at a preset velocity and preset temperature to said cold transmission surface ( 9 ). Furthermore, the system provides a great autonomy because it can store a great quantity of frigories.
