Description
しかし、特許文献2の技術のように、温度センサとは別に水温センサを設けて水抜けを検知していたのではセンサが複数になるため、装置が複雑になる上、装置のコストが高くなる。
そのため、半導体素子からの熱を放熱するインバータ冷却装置のような放熱部材を備えた半導体装置であって、冷却配管中に水温センサを用いることなく、簡易で且つ廉価な構成で正確に水温を検出することができる技術が求められる。
ΔT1=(Ppm/Q)×A
また、半導体装置10は、電動車両や、いわゆるハイブリット車両に搭載される他、舶用や一般産業用に供することもできる。

- 発熱する半導体素子と、
該半導体素子を一方の面に実装する絶縁基板と、
該絶縁基板の他方の面に設けられ前記半導体素子からの熱を放熱する放熱部材とを備える半導体装置であって、
前記絶縁基板の一方の面に実装される温度センサと、
前記絶縁基板上に実装された前記半導体素子及び前記温度センサとの間に、前記半導体素子から発熱の熱伝導を防止する熱伝導防止部とを備えており、
前記熱伝導防止部は、前記絶縁基板の両面に形成されたスリットであることを特徴とする半導体装置。
