According to the high power dissipation, high insulating requirement and enclosed limited space of the HV Power House used in the Ocean Observatory systems' Junction Box, we designed a special heat dissipation system by oil-filling and used an elastic component for volume compensation of thermal expansion. The result of the FVM numerical simulation indicated: Under this system, we can control the temperature of the HV Power House very well. It is also greatly helpful to solve the local over-high temperature problem occurring in some high power components to make sure that the Seafloor Junction Box can work reliably in the designed temperature and pressure range.
