Description
Technical field
The present invention relates 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 extremely market favor of the smaller DC-DC converter of volume.But existing DC-DC converter, with DC-DC
The integration density of converter internal power device is improved, and the heating of the whole machine of DC-DC converter is also further obvious, DC-DC
The heat dispersion of the whole machine of converter 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 small size, high power density direct current/straight
Stream transformer is increasingly paid attention to by everybody.However, for small size, the DC-DC converter of high power density,
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, is set with tackling heat
The special of meter treatment is 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 meeting water can then produce short circuit, 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 U of Chinese patent literature CN 204578358 turn the utility model discloses the DC/DC that a kind of battery truck is used
Parallel operation, it includes shell and substrate, and shell includes the case that base plate and cover are placed on base 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 the enging cabin of electric automobile
It is interior, the enging cabin directly contact of the converter base plate and electric automobile so that the base 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, and influence converter is used
Life-span.Therefore DC-DC converter needs a radiating good and is capable of the external structure of effective water proof and dust proof.
The content of the invention
The technical problems to be solved by the invention are that now chlamydate radiating effect is poor and without effective waterproof and dustproof
Problem, there is provided a kind of new heat-dissipating casing.Heater members heat dissipation problem is can solve the problem that using the heat-dissipating casing while accomplishing have
Imitate the advantage of waterproof and dustproof.
For the technical scheme for solving above-mentioned technical problem present invention use is as follows：A kind of heat-dissipating casing, including housing and
