Exchanger having a tube and fin bundle and comprising: a duct () through which a cryogenic fluid can flow between a fluid inlet () into the exchanger and a fluid outlet () from the exchanger; and a system of flat, continuous and parallel fins () through which said duct passes inside the exchanger, it being possible for air () to circulate within the exchanger by passing through channels delimited by the space between the duct and the parallel fins. The exchanger is characterized in that it comprises at least two independent ducts () for the circulation of cryogenic fluid within the exchanger.

Compact exchanger for indirect-injection cyrogenic transportation

A method for managing the operation of a refrigerated truck for transporting heat-sensitive products, of the indirect-injection type, in which the parameter &#x394;T=&#x2212;T(T: temperature of the air coming into contact with the heat exchanger internal to the truck as a result of the action of the fan, T: temperature to be set in the chamber inside the truck) is determined in real time and in which if &#x394;T is greater than an upper setpoint value &#x394;T, a rapid-pressurization (RMP) circuit is activated to vaporize some cryogen and thus increase the pressure in the head of gas above the reserve of cryogen of the truck.

Method of managing the operation of a refrigerated truck for transporting heat-sensitive products by modifying the refrigeration power

The invention relates to a method for transporting heat-sensitive products in a refrigerated lorry of the indirect injection type, wherein the temperature Tinside the storage chamber is regulated by varying the pinch of the exchanger (Pinch=T&#x2212;TFluid outflow) according to the position of the internal temperature Tin relation to a temperature set value.
