A high voltage fluid heater (hvch)

A high voltage fluid heater comprising:

• a housing comprising at least one of walls and openings along different sides thereof to define at least one enclosure,
• the housing further comprising an inlet and an outlet for ingress and egress of fluid from inside the housing;
• a printed circuit board disposed along a first plane along one side of the housing;
• at least one heating element controlled by the printed circuit board;
• a power transistor assembly comprising a plurality of power transistors,
• each power transistor comprising a plurality of lead frames emanating therefrom and adapted to be connected to the printed circuit board;
• at least one thermal pad disposed along a side wall of the housing;
• at least one spring element adapted to be mounted on the housing to urge the power transistors against the thermal pad to enable cooling of the power transistors through the fluid circulating across the high voltage fluid heater,
• wherein the power transistor assembly along with the thermal pad and the spring element are disposed and extending along the side wall that is along a plane at an angle to the first plane.
