A high voltage fluid heater (100) includes a housing (10), a PCB (20), at least one heating element (30), a power transistor assembly (40), at least one thermally conductive pad (50), and at least one spring element (60) mounted to the housing (10) by a bolt (70). The PCB (20) controls the heating element (30). The power transistor component (40) includes a power transistor (42). Each power transistor (42) includes a lead frame (42a) emanating therefrom and angularly connected to the PCB (20). The spring element (60) urges the power transistor (42) towards a side wall (12c) of the housing (10). The thermally conductive pad (50) is sandwiched between the spring element (60) and the side wall (12c). Each of the power transistor component (40), the thermally conductive pad (50), and the spring element (60) is disposed parallel to each other and along a plane at an angle to the PCB (20).

    一种高电压流体加热器(100)包括壳体(10)、PCB(20)、至少一个加热元件(30)、功率晶体管组件(40)、至少一个导热垫(50)和至少一个通过螺栓(70)安装到壳体(10)上的弹簧元件(60)。PCB(20)控制加热元件(30)。功率晶体管组件(40)包括功率晶体管(42)。每个功率晶体管(42)包括从其发出并成角度地连接到PCB(20)的引线框(42a)。弹簧元件(60)将功率晶体管(42)推向壳体(10)的侧壁(12c)。导热垫(50)夹在弹簧元件(60)和侧壁(12c)之间。所述功率晶体管组件(40)、所述导热垫(50)和所述弹簧元件(60)中的每一个彼此平行并且沿着与所述PCB(20)成一定角度的平面设置。
