The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

Example 1

Referring to fig. 1-6, an embodiment of the present utility model provides an electric cabinet for a high-power switching power supply, including: the high-power switch power supply comprises a box body 1, a high-power switch power supply assembly 2 and an electric assembly 3; wherein,,

the inside of the box body 1 is provided with a first chamber 4 and a second chamber 5 which are distributed in sequence from top to bottom or from bottom to top;

the high-power switching power supply assembly 2 is arranged in the first chamber 4;

the electrical assembly 3 is arranged in the second chamber 5.

It should be noted that, as the size of the high-power switching power supply 2 is larger than that of a general switching power supply, the space required to occupy the electric cabinet is also enlarged, but the space is limited by the application environment of the rack-mounted liquid cooling air conditioner, and the length and width of the electric cabinet cannot be enlarged, so the embodiment has better design on the structure of the electric cabinet, and proposes the idea of utilizing the depth space of the electric cabinet, that is, by designing the cabinet body 1 in an upper layer and a lower layer, and arranging the high-power switching power supply component 2 in the first chamber 4, and arranging the electric component 3 in the second chamber 5 in a different layer, the depth space of the electric cabinet is enlarged compared with the prior art, which is beneficial to layered arrangement of the high-power switching power supply component 2 and the electric component 3, and the length and width space of the high-power switching power supply component 2 is not separated by the electric component 3 because the high-power switching power supply component 3 is not located in the same layer, so that the arrangement area of the electric cabinet is reduced, the space utilization rate is improved, and the independent chamber is improved, and the heat exchange air flow is ensured to be smooth, or the heat dissipation capacity of the high-load power supply 2 can be avoided.

Referring again to fig. 1, in the present embodiment, the interior of the case 1 is partitioned into the first chamber 4 and the second chamber 5 by a partition plate 6.

The spacer plate 6 may be mounted to the inside of the case 1 by bolts, but is not limited thereto.

Referring to fig. 2, and referring again to fig. 1, in the present embodiment, a connecting member 7 is disposed on an inner wall of the case 1, and the connecting member 7 can move up and down along an inside of the case 1;

the spacer plate 6 is connected with the inner wall of the box 1 through the connecting piece 7.

It should be noted that, in the process that the connecting member 7 moves up and down along the inside of the case 1, the spacer plate 6 can also move up and down along with the connecting member 7 to adjust the volumes of the first chamber 4 and the second chamber 5, and when the volume of the first chamber 4 is reduced, the volume of the second chamber 5 must be increased, and similarly when the volume of the first chamber 4 is increased, the volume of the second chamber 5 must be reduced. The purpose of this design is to make it possible to more effectively and reasonably arrange the internal depth space of the case 1 by providing a larger space for one of the large volume and the large heat generation amount according to the volumes and the heat generation amounts of the high-power switching power supply unit 2 and the electric unit 3.

In this embodiment, the electrical component 3 is arranged on the side of the spacer plate 6 facing the second chamber 5.

It should be noted that, when the spacer plate 6 is disposed between two chambers, the electrical component 3 may be disposed on the inner wall of the case 1 corresponding to the second chamber 5, since the other surface of the spacer plate 6 is directed toward the first chamber 4, so that it is also subjected to heat transfer in the first chamber 4, thereby affecting the electrical component 3, when the electrical component 3 is disposed on the surface of the spacer plate 6 directed toward the second chamber 5.

Referring to fig. 2 again, in this embodiment, an air inlet hole 8 and an air outlet hole 9 that are communicated with the first chamber 4 are formed in the box 1 at a position corresponding to the first chamber 4.

It should be noted that, in order to facilitate heat dissipation, the path between the air inlet 8 and the air outlet 9 should be reasonably designed to enable the heat flow to flow along the same direction all the time, that is, the air inlet 8 and the air outlet 9 should be correspondingly disposed at two sides of the box 1. The air inlet hole 8 is used as an air inlet, the air outlet is formed in the air outlet, the high-power switch power supply assembly 2 is exhausted by a self-contained cooling fan, heat is taken away from one side to the other side, and the whole air duct is only the high-power switch power supply assembly 2, and the air source is ambient air outside the electric cabinet, so that the high-power switch power supply assembly 2 can be fully cooled.

Referring to fig. 3-6, in the present embodiment, the high-power switching power supply assembly 2 includes a switching power supply fixing member 201, a switching power supply body 202, and a switching power supply connector 203;

the switch power supply fixing piece 201 is a hollow structure with two through ends, and is connected with the inner wall of the box body 1;

the switch power connector 203 is disposed in the switch power fixing member 201 and is located at one end of the switch power fixing member 201;

the switch power body 202 is movably disposed in the switch power fixing member 201, and is connected to the switch power connector 203 in a pluggable manner.

It should be noted that, in this embodiment, the structure of the high-power switching power supply assembly 2 is better designed, so that the hot plug of the switching power supply body 202 is realized, and when the switching power supply body 202 needs to be maintained or replaced, only the switching power supply body 202 needs to be pulled out from one side, so that the switching power supply body 202 can be replaced or maintained under the condition that the unit power supply does not lose power.

In addition, even if the switching power supply connector 203 is disposed at one end of the switching power supply fixing member 201 that is originally penetrated, the switching power supply connector 203 does not completely seal the switching power supply fixing member 201, that is, both ends of the switching power supply fixing member 201 that is originally penetrated are still partially penetrated, and can cooperate with the air inlet hole 8 and the air outlet hole 9, so that heat can flow from one side of the case 1 to the other side of the case 1 after passing through the switching power supply fixing member 201.

Referring again to fig. 2, in the present embodiment, a cover plate 10 is disposed on the case 1 at a position corresponding to the first chamber 4, and the cover plate 10 is detachably or openably connected to the case 1;

the cover plate 10 covers the switch power supply body 202 in the case 1.

When the switching power supply body 202 needs to be repaired or replaced, the cover plate 10 needs to be detached or opened first to pull out the switching power supply body 202 from one side. It will be appreciated that, in order to ensure the installation stability of the switch power supply body 202, the switch power supply body 202 may also be fixed to the switch power supply fixing member 201 by a screw, so that when the switch power supply body 202 needs to be maintained or replaced, after the cover plate 10 is detached or opened, the screw on the switch power supply body 202 needs to be unscrewed, so that the switch power supply body 202 can be hot plugged.

In this embodiment, the air outlet hole 9 is formed in the cover plate 10.

It should be noted that, the number of the air inlet holes 8 and the number of the air outlet holes 9 are not limited, and the air outlet holes 9 may be formed at other positions of the case 1 corresponding to the first chamber 4, except for being formed on the cover plate 10, which is not repeated in this embodiment.

Although the terms of the case, the high power switching power supply assembly, the electrical assembly, the first chamber, the second chamber, the spacer plate, the connector, the air inlet hole, the air outlet hole, the cover plate, etc. are used more herein, the possibility of using other terms is not excluded.
