Description
Technical field
The present invention is a kind of power supply unit, by referring to a kind of power supply unit with dislocation design.
Background technique
In the application of particular power source supply system (such as ATS (automatic power switch) system, hereinafter referred to as ATS
System), to pursue stiffness of system and reliability, power supply more than two can be provided.It is dynamic that normal operation only has one group of power supply
Make, can switch when demand occurs for system by another group of power supply power supply.Since the same time only has the movement of single group power supply, Suo Youre
Loss only occurs in this Working mould group, that is, heat source can be concentrated in specific region, when heat source concentrates in specific region,
It will be not easy because of heat dissipation and distinguished and admirable reduction temperature can not be efficiently used.
It please refers to shown in Fig. 7, is the block diagram of existing ATS system comprising one first power supply mould group 71, one second is powered
Mould group 72 and a fan 73, wherein after the first power supply mould group 71 has one first prime power conversion unit 711 and one first
Level power supply converting unit 712, the second power supply mould group 72 also have one second prime power conversion unit 721 and one second rear class
Power conversion unit 722, wherein the first prime power conversion unit 711, the second prime power conversion unit 721 separately include
The main elements such as circuit of power factor correction (PFC), preceding level processor, the first rear class power conversion unit 712, the second rear class electricity
Source converting unit 722 separately includes the main elements such as DC-DC converting circuit (DC/DC) and rear level processor.
As also shown in fig. 8, the arrangement of ATS system spatially is to enable the one or the two power supply power supply mould group 72 of mould group 71, second
In parallel side by side with its length direction, level power supply turns after the first prime power conversion unit 711 and first of the first power supply mould group 71
Unit 712 is changed then in length direction sequential, after the second prime power conversion unit 721 and second of the second power supply mould group 72
Level power supply converting unit 722 also in length direction sequential, and the fan 73 (not showing in this figure) be usually be located at this first
The outside of two rear class power conversion units 712, the second rear class power conversion unit 722, the distinguished and admirable heat dissipation generated is by rear class
Power conversion unit blows to prime power conversion unit.
It is all deposited due to prime power conversion unit, rear class power conversion unit and is easy to produce the element of high temperature at work,
When distinguished and admirable these heater elements that flow through can make the reduction of its temperature, but increase distinguished and admirable self-temperature, when airflow temperature is cured
Height will be so that heat dissipation effect be more significant.By taking above-mentioned ATS system as an example, such as work is the first power supply mould group 71, and second supplies
Electric mould group 72 is idle, then all heater elements are focused on the same side, and the first power supply mould group 71, second is powered 72 inlet air of mould group
The temperature of mouth is although identical, but passes through the distinguished and admirable because having first passed through the first rear class power conversion unit 712 of the first power supply mould group 71
The thermal energy for carrying under one's arms heater element, it is single using that can not be converted to level power supply before first when the first prime power conversion unit 711
Member 711 plays heat spreading function, and influences integrally and radiating efficiency.
Summary of the invention
In view of the bad disadvantage of the heat dissipation effect of the power supply unit of the ATS system of the prior art, the present invention provides one
Kind has the power supply unit of dislocation design, includes:
One shell has a first side wall and a second sidewall parallel with a first direction, the first side wall, second side
An accommodating space is formed between wall, and the shell is respectively a first end and a second end along the opposite end of the first direction；
One first power supply mould group is the first end and second for being set in the accommodating space of the shell, and being located at the shell
Between end；
One second power supply mould group, be set in the accommodating space of the shell and with the first power supply mould group side by side, this
Two power supply mould groups also are located between the first end of the shell and second end；Wherein
The first power supply mould group has one first prime power conversion unit and one first rear class power conversion unit；This
Two power supply mould groups have one second prime power conversion unit and one second rear class power conversion unit；Wherein, first prime
Power conversion unit, the second rear class power conversion unit are located on the inside of the first side wall of the shell, this before second level power supply turn
Change unit, the first rear class power conversion unit is located on the inside of the second sidewall of the shell.
Due to this first power supply mould group, this second power supply mould group and the fan be along the first direction sequential,
When this has the power supply unit running of dislocation design, outside air is empty by the accommodating of the first end and second end disengaging shell
Between, when the first power supply mould group work, when the second power supply mould group is idle, the first prime power conversion unit of the first power supply mould group,
First rear class power conversion unit distinguishes position on different distinguished and admirable paths, is radiated respectively by the air passed through, by making
Power supply mould group its prime, rear class power conversion unit in work interlock status on different distinguished and admirable paths, and being able to can be effectively
Improve radiating efficiency.
