Abstract

The invention belongs to the cooling technical field of a power circuit system, and discloses a comprehensive cooling housing of a power circuit. The comprehensive cooling housing of a power circuit comprises a lower housing. The lower housing is filled with transformer oil. Sectional material radiators are arranged on the four sidewalls of the housing. A bottom circulation block is arranged at the bottom of the housing, and is connected with the housing through standard pieces. An intelligent cooling fan is fixed on each sectional material radiator. The problem of low cooling efficiency caused by dependency upon metal heat conduction and cooling of fans is overcome, and the problem of abnormal operations caused by overheating of power devices is overcome. The housing also solves the problem of a single way only relying on water or oil cooling. Conventional single water or oil cooling structures and manufacturing processes are simplified. Multiple cooling ways are combined as one way, and work temperature rises of the power circuit are reduced to ensure that the power circuit functions reliably and stably. Through a comprehensive cooling technique, the housing has the technical advantages of being higher in environment adaptability and long in service life, being reliable and stable, etc.

Description

technical field [0001] The invention belongs to the technical field of power circuit system cooling, and in particular relates to a power circuit comprehensive cooling shell. Background technique [0002] Due to the thermoelectric positive feedback effect, high-power circuits and systems that can generate large amounts of heat have high thermal instability, so effective cooling is required for stable applications. If the cooling is not good, the output of the circuit will drift due to heat accumulation, and the protection mechanism will be triggered or the circuit will be damaged if it is serious. Traditional cooling methods usually adopt a single open air cooling, oil immersion, water circulation cooling and oil circulation cooling. Among them, open air cooling is most susceptible to environmental influences, and the cooling effect is unstable; and electronic components are prone to dust accumulation, which is likely to cause safety hazards. The disadvantage of oil-immers...
