Liquid nitrogen & carbon dioxide thermo vanes cold trap exchanger

Abstract

A cold trap heat exchanger with a horizontal and vertical arrangement of vaporization chambers, with vibration pads for vehicle use. Vaporization pipes each have a series of thermo vanes mounted on horizontal arranged pipes. This fluid controls the vaporization of the liquid fluid and surface area causing a liquid film on surface area varies of both tubes and pipes to occur, and this increases the facilitate refrigeration. The pneumatic chambers are filled with liquid N 2 . These gases are controlled through regulated orifice for back pressure on gas turbines used to move atmosphere circuits across cold trap tubes and veins and flow through vanes for cooling control of designed areas and chambers in cooling application that may be required for cooling.

What is claimed is: 
     
         1 . In a liquid Nitrogen capillary tube refrigerative system wherein liquid Nitrogen is passed through a cooling tube having a plurality of capillary tube loops mounted on an exterior side of the cooling tube and wherein the capillary tube loops are in fluid communication with the interior of the cooling tubes, the improvement wherein the capillary tube loops are enclosed in heat transmissive fins that contact outer surfaces of the capillary tubes and have sides that extend across the loops, the fins increasing the heat dissipation surface of the capillary tube heat exchanger and increasing the efficiency of the liquid Nitrogen heat exchanger. 
     
     
         2 . A capillary tube heat exchanger as in  claim 1  wherein the cooling tube has at least two capillary tube loops at different radial positions at approximately the same axial position on the cooling tube and the fins include a single fin that covers both loops and provides an increased cooling surface representing the entire area between the loops as well as the area inside the individual loops.
