CIRCUIT CONFIGURATION BODY

To provide a circuit configuration body that can reduce a mount area occupied by a heat conductive member in a housing and improve the heat dissipation efficiency of a heat generating component using an energizing bus bar.SOLUTION: A circuit configuration body 10 includes a heat generating component 22 and an energizing bus bar 26. The energizing bus bar 26 has a hollow tube path 32 including a first opening 28 opening to one end portion of the energizing bus bar 26 and a second opening 30 opening to the other end portion of the energizing bus bar, the first opening and the second opening extending through the energizing bus bar 26. The energizing bus bar 26 includes a first connection pipe 60 that is fluid-tightly connected to one end portion of the energizing bus bar 26, surrounds the first opening 28, and communicates with the first opening 28, a second connection pipe 62 that is fluid-tightly connected to the other end portion of the energizing bus bar 26, surrounds the second opening 30 and communicates with the second opening 30. The first connection pipe 60 has a first pipe connecting port 68 connectable to a refrigerant source 34, and the second connection pipe 62 has a second pipe connecting port 70 connectable to the refrigerant source 34.SELECTED DRAWING: Figure 7 【課題】筐体内において熱伝導部材で占められる搭載面積を小さくできて、通電用バスバーを用いた発熱部品の放熱効率の向上を図ることができる、回路構成体を開示する。【解決手段】回路構成体１０が、発熱部品２２と通電用バスバー２６とを備え、通電用バスバー２６は、通電用バスバー２６を貫通して延びて通電用バスバー２６の一方の端部に開口する第１開口２８および他方の端部に開口する第２開口３０とを含む中空管路３２を有し、通電用バスバー２６は、通電用バスバー２６の一方の端部に流体密に連結され、第１開口２８を囲って第１開口２８と連通する第１接続管体６０と、通電用バスバー２６の他方の端部に流体密に連結され、第２開口３０を囲って第２開口３０と連通する第２接続管体６２と、を有し、第１接続管体６０は冷媒源３４に接続可能な第１管路連結口６８を有し、第２接続管体６２は冷媒源３４に接続可能な第２管路連結口７０を有している。【選択図】図７
