The present invention relates to a soldering junction-type inverter and a hybrid vehicle with a soldering junction-type inverter applied thereto. The hybrid vehicle according to the present invention comprises a Hybrid Power Control Unit (HPCU) (170) which includes: a power module (10 or 10-1) configured to include chips (15-1 and 15-2), adapted to generate heat at a self heat generation amount during operation, therein; a cooler (20-1 and/or 20-2) configured to cool an amount of heat generated by the power module (10 or 10-1); chip SIM parts (31) configured to bond the chips (15-1 and 15-2) to the power module (10 or 10-1) and to form inner solder layers; and a cooler SIM part (33) configured to bond the power module (10 or 10-1) to the cooler (20-1 and/or 20-2) and to form an outer solder layer. Accordingly, reduction of production costs can be achieved while more improved cooling performance is provided without having low heat conductivity of a Thermal Interface Material (TIM) and unevenness of application thickness and experiencing a pump-out phenomenon. In particular, improved cooling performance of the HPCU (170) enables production costs of the HPCU (70) to be reduced, and improves competitiveness through preoccupation of a technologically advantageous position.

    본 발명의 하이브리드 차량에는 동작 시 자기 발열량을 갖는 칩(Chip)(15-1,15-2)이 내부에 구비된 파워 모듈(10,10-1), 파워 모듈(10,10-1)의 발열량을 냉각하는 냉각기(20-1,20-2), 칩(Chip)(15-1,15-2)과 파워 모듈(10,10-1)을 접합해 내부 솔더층을 이루는 칩 SIM(31), 파워 모듈(10,10-1)과 냉각기(20-1,20-2)를 접합해 외부 솔더층을 이루는 냉각기 SIM(33)으로 구성된 HPCU(Hybrid Power Control Unit)(170)가 포함됨으로써 TIM(Thermal Interface Material)의 낮은 열전도율과 도포 두께 불일치 및 펌프아웃 현상 없이 보다 향상된 냉각 성능으로 원가 절감이 이루어지고, 특히 향상된 HPCU(170)의 냉각성능으로 HPCU(70)의 원가절감 및 기술우위선점을 통한 경쟁력 향상도 이루어지는 특징이 있다.
