Cooling Unit

Abstract

A cooling unit has a first door hinged to the cooling unit away from the second door and has a second door hinged to the cooling unit away from the first door, each door rotatably opening way from one another to access the chamber. The first side of the first door faces the second side of the second door when the first door and the second door are in closed configuration to close the chamber. The first side of the first door has a first wall and a second wall forming a flat-surface-channel bottom between the first wall and the second wall. To fit between the first wall and the second wall, the second side of the second door has a gasket having an elastic surface. The elastic surface directly engages the flat-surface-channel bottom between the first wall and the second wall.

         5 . The cooling unit of  claim 1 , wherein the first door has an adjacent side to the first side, wherein the adjacent side has an adjacent sidewall that extends over a first wall end and a second wall end. 
     
     
         6 . The cooling unit of  claim 1 , wherein the elastic surface has a preformed flat-engaging surface that directly engages the flat-surface-channel bottom between the first wall and the second wall when the first door and the second door are in the closed configuration. 
     
     
         7 . The cooling unit of  claim 1 , wherein the elastic surface is an elastically flexible surface without a preformed flat-engaging surface, wherein the elastically flexible surface pliably forms a flat-engaging surface when the elastically flexible surface engages the flat-surface-channel bottom between the first wall and the second wall when the first door and the second door are in the closed configuration. 
     
     
         8 . The cooling unit of  claim 7 , the distance from the flat-surface-channel bottom to a top surface of the second side when the first door and the second door are closed, d 1 , is shorter than the distance from a tip of the gasket to the top surface of the second side when the second door is opened, d 2 . 
     
     
         9 . The cooling unit of  claim 1 , wherein the elastic surface has a groove wherein the groove is directly over the flat-surface-channel bottom when the first door and the second door are in the closed configuration. 
     
     
         10 . The cooling unit of  claim 9 , wherein the groove forms an air pocket between the elastic surface and the flat-surface-channel bottom when the first door and the second door are in the closed configuration. 
     
     
         11 . The cooling unit of  claim 9 , wherein the elastic surface has a plurality of grooves wherein at least one of the grooves is directly over the flat-surface-channel bottom when the first door and the second door are in the closed configuration. 
     
     
         12 . The cooling unit of  claim 11 , wherein at least one of the grooves forms an air pocket between the elastic surface and the flat-surface-channel bottom when the first door and the second door are in the closed configuration. 
     
     
         13 . The cooling unit of  claim 1 , wherein the elastic surface has a groove wherein the groove is not directly over the flat-surface-channel bottom when the first door and the second door are in the closed configuration. 
     
     
         14 . The cooling unit of  claim 1 , wherein the elastic surface has a pair of grooves wherein the pair of grooves are not directly over the flat-surface-channel bottom when the first door and the second door are in the closed configuration. 
     
     
         15 . A cooling unit comprising a chamber with a first door and a second door, wherein the first door is hinged to the cooling unit away from the second door and the second door is hinged to the cooling unit away from the first door so that the first door and the second door rotatably open way from one another to access the chamber, wherein the first door has a first side and the second door has a second side, wherein the first side of the first door faces the second side of the second door when the first door and the second door are in closed configuration to close the chamber, wherein the first side of the first door has a first wall and a second wall forming a flat-surface-channel bottom between the first wall and the second wall, wherein the second side of the second door has a gasket having an elastic surface, and wherein the elastic surface directly engages the flat-surface-channel bottom between the first wall and the second wall. 
     
     
         16 . The cooling unit of  claim 15 , wherein each of an outer surface of the first wall and an outer surface of the second wall is a curved surface. 
     
     
         17 . The cooling unit of  claim 15 , wherein the first side has an endcap between a first wall end and a second wall end. 
     
     
         18 . The cooling unit of  claim 15 , wherein the first door has an adjacent side to the first side, wherein the adjacent side has an adjacent sidewall that extends over a first wall end and a second wall end.
