In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 2, fig. 3, and fig. 4, embodiment 1 of the present invention provides a water-cooled power supply cabinet, which includes a housing 1, wherein circuits for rectifying and regulating voltage need to be installed inside the housing 1, and these circuits release heat during operation, so that heat dissipation is needed.
The housing 1 shown in fig. 2 is directed upwards on its top side, provided with a top plate 5, on the front side of which housing 1 a water inlet 3 and a water outlet 4 are mounted. The water inlet 3 and the water outlet 4 are connected with an external water pump assembly, and cooling liquid can enter the water inlet 3 and flow back from the water outlet 4 under the action of pressure.
As shown in fig. 3 and 4, the bottom surface of the housing 1 is provided with cooling water channels, which include a first main water channel 6, a second main water channel 15 and a plurality of parallel auxiliary water channels, as shown in fig. 3, in this embodiment, five parallel auxiliary water channels, namely a first auxiliary water channel 7, a second auxiliary water channel 8, a third auxiliary water channel 9, a fourth auxiliary water channel 10 and a fifth auxiliary water channel 11 are included.
The first main water channel 6 and the second main water channel 15 are respectively positioned at two sides of the auxiliary water channel and are arranged in parallel. The first auxiliary water channel 7, the second auxiliary water channel 8, the third auxiliary water channel 9, the fourth auxiliary water channel 10 and the fifth auxiliary water channel 11 are arranged in parallel and are vertical to the first main water channel 6 and the second main water channel 15.
First main water course 6 communicates with water inlet 3, and second main water course 15 communicates with delivery port 4, and five vice water courses communicate first main water course 6 and second main water course 15, and the coolant liquid flows into first main water course 6 from water inlet 3, flows into second main water course 15 through five vice water courses, then flows out from delivery port 4.
The case in this embodiment adopts the design of parallelly connected vice water course, has expanded cooling zone area, has reduced the flow resistance to the coolant liquid, and the coolant liquid reposition of redundant personnel absorbs the heat, can also reduce the interact between the heat source, has improved the radiating efficiency.
Because the parallel auxiliary water channels are provided with a plurality of auxiliary water channels, if the parallel auxiliary water channels are not adjusted, the cooling liquid can firstly flow away from the adjacent auxiliary water channels, and the flow rate of the cooling liquid in the farther auxiliary water channels cannot be ensured, so that a plurality of steps 14 are arranged in the cooling water channel, the steps 14 are gradually increased from the near end to the far end of the positions of the water inlet 3 and the water outlet 4, the height of the cooling water channel is gradually reduced to ensure the flow rate of the cooling liquid, the flow rate of the cooling liquid in the auxiliary water channel at the far end is kept normal, the heat dissipation effect is not influenced, and good flow division.
