Fig. 1 is refer to, it is the layout signal for illustrating the multichannel power supply 100a according to the embodiment of the utility model one
Figure.In the present embodiment, as shown in figure 1, a kind of multichannel power supply 100a comprising at least one first power conversion unit 110,
At least one second power conversion unit 120 and radiating element 130.First power conversion unit 110 has multiple first sub-cells
(the first sub-cell 111a and the first sub-cell 111b as described below), the first sub-cell is electrically connected to each other, and is had
An at least first heating element 112.Second power conversion unit 120 has multiple second sub-cells (as described below second
Sub-cell 121a and the second sub-cell 121b), the second sub-cell is electrically connected to each other, and with an at least second heatiing element
122.Radiating element 130 configures substantially along an at least heat eliminating medium direction HD, to disperse the hair of first heating element 112 and second
The heat that thermal element 122 is generated, wherein the first sub-cell and the second sub-cell, at least partly interlock along heat eliminating medium direction HD
Arrangement.In the application of practice, first heating element 112 includes electromagnetic component 113, and second heatiing element 122 can include electricity
Magnetic cell 123.According to actual state, first heating element 112 and second heatiing element 122 can also include semiconductor element,
Such as the first power component 116 and the second power component 117.
For example, as shown in figure 1, the first power conversion unit 110 has the first sub-cell 111a and single for the first time
First 111b, the first sub-cell 111a and the first sub-cell 111b are electrically connected to each other, and the first sub-cell 111a and first
Sub-cell 111b has an at least first heating element 112 respectively.In addition, the second power conversion unit 120 has second of list
First 121a and the second sub-cell 121b, the second sub-cell 121a and the second sub-cell 121b are electrically connected to each other, and second
Sub-cell 121a and the second sub-cell 121b have an at least second heatiing element 122 respectively.Furthermore, the first power conversion list
The the first sub-cell 111b and the second sub-cell 121b of the second power conversion unit 120 of member 110 position are exchanged each other so that
First sub-cell 111b of the first power conversion unit 110 and the second sub-cell 121b of the second power conversion unit 120 are at least
It is staggered along heat eliminating medium direction HD.
When the first power conversion unit 110 and the second power conversion unit 120 are operated together, due to the first sub-cell
111a, the first sub-cell 111b, the second sub-cell 121a and the second sub-cell 121b produce heat, therefore, multichannel electricity
Source 100a heating is also than more uniform, and the first sub-cell 111a, the first sub-cell 111b, the second sub-cell 121a and second
The heat that sub-cell 121b is generated, is dispersed by radiating element 130 substantially along heat eliminating medium direction HD.
However, if only one of which is in fortune in the first power conversion unit 110 and the second power conversion unit 120
OK, for example only the first power conversion unit 110 is run, and the second power conversion unit 120 is not run or only with small work(
Rate is run, then, for the first sub-cell 111b of the first power conversion unit 110, due to along heat eliminating medium direction HD
The second sub-cell 121a positioned at the first sub-cell 111b upstreams is not run or only band small-power is run, therefore, radiator
Part 130 to the first sub-cell 111b before radiating, without being radiated to the second sub-cell 121a, or only need to be to second
Sub-cell 121a is radiated with the low-grade fever that small-power is run and produced, therefore, 130 pair of first power conversion unit of radiating element
110 the first sub-cell 111b remains to reach good radiating effect.Even if that is, multichannel power supply 100a the first work(
The power conversion unit 120 of rate converter unit 110 and second be not simultaneously run, or the first power conversion unit 110 and
Without operation or only, band small-power is run one of in second power conversion unit 120, and multichannel power supply 100a is remained to
Overall uniform radiating effect is reached, so that multichannel power supply 100a loss reduction and conversion efficiency increase so that lead to more
Road power supply 100a reliability is effectively improved.
Vice versa, if only the second power conversion unit 120 is run, and the first power conversion unit 110 is not transported
Row or the only operation of band small-power, then, for the second sub-cell 121b of the second power conversion unit 120, due to edge
The first sub-cell 111a that heat eliminating medium direction HD is located at the second sub-cell 121b upstreams does not run or only transported with small-power
OK, therefore, radiating element 130 to the second sub-cell 121b before radiating, without being radiated to the first sub-cell 111a,
Or the first sub-cell 111a need to only be radiated with the low-grade fever that small-power is run and produced, therefore, radiating element 130 pair the
Second sub-cell 121b of two power conversion units 120 remains to reach good radiating effect.
More specifically, the first sub-cell (such as including the first sub-cell 111a and the first sub-cell 111b) and second
Sub-cell (such as including the second sub-cell 121a and the second sub-cell 121b) is arranged in ranks along line direction, and single for the first time
Member be staggered with the second sub-cell at least partially along line direction, that is, it is as exemplified above for, the first power conversion unit 110
First sub-cell 111b and the second power conversion unit 120 the second sub-cell 121b are at least staggered along line direction.At this
In embodiment, line direction is essentially the same as heat eliminating medium direction HD.
