Refrigerator unit and/or freezer unit

Abstract

The present invention relates to a refrigerator unit and/or a freezer unit having an inner container for the reception of refrigerated goods and/or frozen goods, having a magnetic cooler as well as having a heat exchanger with a heat carrier medium located therein for the refrigeration of the inner space of the inner container, wherein the heat exchanger is made such that the heat transfer from the inner space of the inner container to the heat carrier medium only takes place via the wall of the inner container or only via the wall of the heat exchanger.

1 . A refrigerator unit and/or a freezer unit having an inner container for the reception of refrigerated goods and/or frozen goods, having a magnetic cooler as well as having a heat exchanger with a heat carrier medium located therein for the refrigeration of the inner space of the inner container, wherein the heat exchanger is made such that the heat transfer from the inner space of the inner container to the heat carrier medium only takes place via the wall of the inner container or only via the wall of the heat exchanger. 
   
   
       2 . A refrigerator unit and/or a freezer unit having an inner container for the reception of refrigerated goods and/or frozen goods, having a magnetic cooler as well as having a heat exchanger with a heat carrier medium located therein for the refrigeration of the inner space of the inner container, wherein the heat exchanger is an integral component of the inner container; or the heat exchanger is in direct communication with the inner container. 
   
   
       3 . A refrigerator unit and/or a freezer unit in accordance with  claim 2 , wherein the unit is made such that the heat transfer from the inner space of the inner container to the heat carrier medium only takes place via the wall of the inner container or only via the wall of the heat exchanger. 
   
   
       4 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger is located on the side of the inner container directed to the inner space or on the side of the inner container directed outwardly or forms a section of the inner container. 
   
   
       5 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger is made as a pan. 
   
   
       6 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger has passages or pipes for the conducting of the heat carrier medium. 
   
   
       7 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger is arranged such that it is surrounded by heat insulation region-wise. 
   
   
       8 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger is fixed on the inner container by ultrasound. 
   
   
       9 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger is in communication with pipes for the supply and drainage of the heat carrier medium into or out of the heat exchanger; and one or both of these pipes are made from plastic. 
   
   
       10 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heat exchanger is primarily or exclusively made from plastic. 
   
   
       11 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the wall or at least one of the walls through which the heat is transferred from the inner space of the unit to the heat carrier medium has means by which the heat transfer is improved. 
   
   
       12 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger is located on the side of the inner container directed to the inner space or on the side of the inner container directed outwardly or forms a section of the inner container. 
   
   
       13 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger is made as a pan. 
   
   
       14 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger has passages or pipes for the conducting of the heat carrier medium. 
   
   
       15 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger is arranged such that it is surrounded by heat insulation region-wise. 
   
   
       16 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger is fixed on the inner container by ultrasound. 
   
   
       17 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger is in communication with pipes for the supply and drainage of the heat carrier medium into or out of the heat exchanger; and one or both of these pipes are made from plastic. 
   
   
       18 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the heat exchanger is primarily or exclusively made from plastic. 
   
   
       19 . A refrigerator unit and/or a freezer unit in accordance with  claim 3 , wherein the wall or at least one of the walls through which the heat is transferred from the inner space of the unit to the heat carrier medium has means by which the heat transfer is improved. 
   
   
       20 . A refrigerator unit and/or a freezer unit in accordance with  claim 2 , wherein the heat exchanger is located on the side of the inner container directed to the inner space or on the side of the inner container directed outwardly or forms a section of the inner container.
