Peltier device and temperature regulating container equipped with the peltier device

Abstract

An object of the present invention is to provide a Peltier device capable of retaining a certain temperature at a high accuracy by using a conductive glass consisting primarily of vanadate as an electrode, excellent in handleability, easy in temperature regulation, excellent in stability of cooling performance, capable of securely preventing an electrode from corrosion resulting from chemicals or dew condensation etc., and excellent in reliability and durability of the electrode. The Peltier device has a heat absorbing portion and a heat emitting portion, in which at least the electrode of the heat absorbing portion is formed with the conductive glass consisting primarily of vanadate.

1 . A Peltier device having a heat absorbing portion and a heat emitting portion, wherein at least an electrode of the heat absorbing portion is formed with a conductive glass consisting primarily of vanadate. 
   
   
       2 . A temperature regulating container having a container main body and the Peltier device as set forth in  claim 1  which is placed on the bottom or the side of the container main body. 
   
   
       3 . The temperature regulating container as set forth in  claim 2 , wherein the container main body is at least partially formed with the conductive glass. 
   
   
       4 . The temperature regulating container as set forth in  claim 3 , wherein the electrode of the heat absorbing portion of the Peltier device is the conductive glass which forms at least a part of the container main body. 
   
   
       5 . The temperature regulating container as set forth in any one of  claim 2  to  claim 4 , which has heating means placed on the bottom or the side of the container main body. 
   
   
       6 . The temperature regulating container as set forth in  claim 5 , wherein the heat element of the heating means is the conductive glass which forms at least a part of the container main body. 
   
   
       7 . The temperature regulating container as set forth in  claim 6  which has an insulation portion for insulating the conductive glass acting as the electrode of the heat absorbing portion of the Peltier device and the conductive glass acting as the heat element of the heating means. 
   
   
       8 . The temperature regulating container as set forth in any one of  claim 3  to  claim 7 , wherein the conductive glass is film-formed on the outer surface of the container main body.
