Heat exchange device

Abstract

The present invention provides a solution for increasing the effectiveness of cooling and freezing processes in a heat exchange device. One of the important requirements of a heat exchange device is to keep a uniform temperature on the surface during the process. The achievement of approximately uniform temperature on the surface of the heat exchange device and on both its bottom and upper is possible with the use of a special cross-sectional form of the channels for refrigerant flow.

What is claimed is:  
     
         1 . A heat exchange device comprised of a body with upper and lower sides, inside channels including a top, a bottom and lateral sides, supply header with an inlet, and discharge header with an outlet while said channels having a cross-sectional height greater than the width.  
     
     
         2 . A heat exchange device, according to  claim 1 , with the form of said channels' cross-section is polygonal, oval, elliptical, cross-shaped, star-shaped, round-shaped and any combination of the above.  
     
     
         3 . A heat exchange device according to the  claim 1 , with additional channels, sealed on the sides and free of refrigerant, said device is placed between the channels containing refrigerant.
