Description

A kind of heat-dissipating casing

Technical field

It the utility model is related to a kind of heat-dissipating casing.

Background technology

The design of DC-DC converter just increasingly develops towards high-power, small size direction, power density it is higher and The smaller DC-DC converter of volume is favored by market.But existing DC-DC converter, with DC-DC The integration density of converter internal power device improves, and the heating of DC-DC converter complete machine is also further obvious, DC-DC The heat dispersion of converter complete machine is in urgent need to be improved.With the application demand to high power DC/direct current transducer equipment increasingly Extensively, to meet the market demand of multifunction, increasing electronic component is integrated with DC-DC converter, together When DC-DC converter external dimensions also limited by more strict, therefore the direct current of small size, high power density/straight Stream transformer is increasingly paid attention to by everybody.However, for small size, high power density DC-DC converter for, Radiating is then a big problem.Due to the quality of DC-DC converter external structure design, DC-DC will be directly affected The life and reliability of converter, so DC-DC converter needs the good external structure of a radiating, set with tackling heat Meter processing is especially asked.The use environment of DC-DC converter is severe simultaneously, and the debris such as dust, rainwater can enter direct current/straight Inside stream transformer, electronic device is most afraid of water, and short circuit can then be produced by meeting water, and excessive dust aggregation can then influence the normal hair of performance Wave, if circuit board and electric elements are closed to come, temperature rise is too high and can burn, and directly affects service life.

And for example the utility model discloses DC/DC turns that a kind of battery truck uses by Chinese patent literature CN 204578358U Parallel operation, it includes shell and substrate, and shell includes bottom plate and cover is placed on case on bottom plate, and shell is provided with output port and defeated Inbound port；Power device is disposed with substrate；Substrate includes aluminium base, the back side of more than one aluminium base and the inwall of shell Closely it is fixed on the inwall of shell；Power device is arranged in the aluminium base that the more than one back side is close to the inwall of shell On.Although the DC/DC converters have good heat dispersion, the converter is arranged on to the enging cabin of electric automobile Interior, the converter bottom plate directly contacts with the enging cabin of electric automobile so that the bottom plate is vibrated by electric automobile for a long time And deform, sealing property declines, and causes the debris such as dust, rainwater to be easily accessible converter inside, influences converter use Life-span.Therefore DC-DC converter needs a radiating good and is capable of the external structure of effective water proof and dust proof.
