Description
Technical field
The utility model is related to power supply changeover device field of radiating, radiate in particular to a kind of bi-directional DC-DC converter
Shell.
Background technology
In terms of such product is mainly used in the high voltage power supply conversion of electric vehicle, as battery pack high pressure conversion low pressure is given
24V lead-acid batteries charge, or power for vehicle-mounted low-voltage equipment.
DC-to-dc converter (DC-to-DC converter) is also referred to as DC/DC converters, is the electricity of electric energy conversion
DC power supply can be converted to the DC power supply of different voltages by road.
DC/DC converters can be divided into two kinds of hard switching (Hard Switching) and Sofe Switch (SoftSwitching).
The switching device of hard switching DC/DC converters is switched on or off in the case where bearing voltage or flowing through electric current
Circuit, therefore larger switching loss (Switching loss) will be will produce during being switched on or off.Sofe Switch DC/
The switching tube of DC converters, during being switched on or off, or the voltage being added on thereon is zero, i.e. zero voltage switch (Zero-
Voltage-Switching, ZVS), or the electric current for passing through switching tube is zero, i.e. Zero Current Switch (Zero-Current-
Switching, ZCS).This Sofe Switch mode can significantly reduce switching loss, and switching frequency is allow to increase substantially,
Condition is created for the miniaturization and modularization of converter.
However, after power supply changeover device realizes miniaturization, too closely due to structure, heat dissipation problem gradually highlights.It is existing
The power supply changeover device shell of technology, radiating efficiency is low, is easy to cause electronic component overheat, to influence power supply changeover device work
Stability.
Utility model content
For this purpose, the main purpose of the utility model is to provide a kind of bi-directional DC-DC converter heat-dissipating casing, with reach as
Lower purpose：Promote the heat dissipation of power supply changeover device, increases the stability of power supply changeover device work.
To achieve the above object, the utility model provides the following technical solutions：
A kind of bi-directional DC-DC converter heat-dissipating casing, including：Shell is aluminum alloy materials cuboid hollow housing；It is multiple
Thermal column is aluminum alloy materials, is vertically installed in the housing upper surface, has gap between the thermal column；Multiple radiating fins
Piece is aluminum alloy materials, is arranged on four sides of the shell, is mutually parallel between the radiating fin；Fixed feet, setting
It is equipped with through-hole among the quadrangle of the housing bottom surface, the fixed feet, is passed through for screw；Control port is set to the shell
Front, for connecting control signal wire；First input/output port is set to the shell left side, for connecting the defeated of power supply
Enter or output line；Second input/output port is set to the shell right side, the input for connecting power supply or output line.
Preferably, the bi-directional DC-DC converter heat-dissipating casing, wherein the housing bottom surface is equipped with opening, opening
Equipped with removably lid, for power supply changeover device to be placed into the shell.
Bi-directional DC-DC converter heat-dissipating casing according to the present utility model promotes air stream by new structural design
It is logical, make the power supply changeover device being mounted in shell be more prone to radiate, ensure that the stability of power supply changeover device work.
