<p>PURPOSE:To constitute the titled detector so that a resistance element is scarcely influenced by a variation of a flow rate of water in a cooling body, and also to raise the current detecting accuracy by connecting a voltage detecting signal line of the current detector to both ends of the resistance element which is positioned in the vicinity of a refrigerant inlet of the cooling body. CONSTITUTION:Plural pieces of resistance elements 1 are connected in parallel, respectively, between two pieces of internal conductors 5 through its lead wire 6, and the internal conductors 5 are connected to two pieces of main circuit conductors 3, respectively. The resistance element 1 is cooled by a refrigerant (water) flowing through a cooling body having a refrigerant inlet 8 and a refrigerant outlet 9 in one end and the other end, respectively. Also, a voltage detecting signal line 4 is connected across a resistance element 1a which is positioned in the vicinity of the refrigerant inlet 8 of the cooling body 7, so as to fetch a voltage drop in the resistance element 1a as a voltage for detecting a current. In such a way, even if the water flow rate varies, it scarcely affects the change of temperature.</p> |
