Example one
Fig. 1 is a schematic structural diagram of a cooling device for electrical equipment according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional view of a cooling device for electrical equipment according to an embodiment of the present invention. As shown in fig. 1 and 2, the electrical equipment cooling device 10 of this embodiment includes a case 1, a plurality of electrical equipment 4 are disposed in the case 1, a cold air channel 11 is formed in a region on the front side of the electrical equipment 4 inside the case 1, a hot air channel 12 is formed in a region on the rear side of the electrical equipment 4 inside the case 1, gaps 41 are formed between the plurality of electrical equipment 4, the cold air channel 11 and the hot air channel 12 are communicated through the gaps 41 between the electrical equipment 4, the electrical equipment cooling device 10 further includes a refrigeration equipment 2, a refrigeration equipment air outlet 21 of the refrigeration equipment 2 is communicated with the cold air channel 11, and a refrigeration equipment air inlet 22 of the refrigeration equipment is communicated with the hot air channel 12.
A conventional electric device 4 is provided with a case 1 at an outside thereof to protect the electric device 4 and prevent dust from being accumulated, so that there is a problem that heat generated in the electric device 4 is blocked by the case 1 and is difficult to be dissipated. In this embodiment, inside the housing 1, a cold air channel 11 is formed in a front area of the electrical equipment 4, a hot air channel 12 is formed in a rear area of the electrical equipment 4, and cold air generated by the refrigeration equipment enters the cold air channel 11 from the air outlet 21 of the refrigeration equipment, passes through the gap 41 between the electrical equipment 4, and after sufficient heat exchange with the electrical equipment 4, the temperature of the cold air rises, enters the hot air channel 12, and then enters the refrigeration equipment from the air inlet 22 of the refrigeration equipment, thereby completing a heat dissipation cycle.
When a plurality of electrical devices 4 are provided in the enclosure 1, the electrical devices 4 are generally stacked, and if the flow direction of the cool air is made to flow from the electrical device 4 provided on the lower layer to the electrical device 4 provided on the upper layer, the heat dissipation of the electrical devices 4 is in a sequential relationship, and the electrical device 4 on the upstream side (provided on the lower layer) where the cool air flows dissipates heat first, and the electrical device 4 on the downstream side (provided on the upper layer) dissipates heat later. When there are many electrical devices 4 in the enclosure 1, there is a possibility that the temperature is high when the cold air reaches the electrical device 4 disposed on the downstream side, so that the electrical device 4 disposed on the downstream side cannot radiate heat well for a long time, which also greatly affects the operation stability of the electrical device 4 disposed on the downstream side where the cold air flows. In other words, this heat dissipation method cannot uniformly dissipate heat of all the electrical devices 4 in the chassis 1. In the present embodiment, when the cold air enters the cold air channel 11, the entire front side of all the electrical devices 4 is contacted with the cold air through the cold air channel 11, the cold air is contacted with all the electrical devices 4 substantially simultaneously, after sufficient heat dissipation is performed, the temperature of the cold air rises, the cold air enters the hot air channel 12, and then enters the refrigeration device from the refrigeration device air inlet 22, and a heat dissipation cycle is completed. In the process, each electrical device 4 basically contacts with the cold air at the same time, and obvious successive heat dissipation is not existed, so that the heat dissipation effect is good, and the good heat dissipation effect can be achieved particularly when the electrical devices 4 in the case 1 are more and generate heat seriously.
In addition, the prior art is a passive heat dissipation process, heat dissipation is realized by means of heat exchange between the electrical equipment and air around the electrical equipment, and the temperature of the air around the electrical equipment is increased along with the lapse of heat dissipation time, so that the heat dissipation effect is greatly reduced; in the present embodiment, even if the temperature of the air around the electrical equipment increases with the passage of time, the refrigeration equipment can continuously and constantly provide cold air for the cabinet 1 in which the electrical equipment 4 is stored without being affected, and thus the heat dissipation effect does not change with the passage of time.
As shown in fig. 1 and 2, the plurality of electrical devices 4 are stacked vertically in the cabinet 1 with a gap 41 therebetween, so that the cold air duct 11 on the front side of the electrical devices 4 and the hot air duct 12 on the rear side of the electrical devices 4 communicate with each other. Alternatively, the cold air device may be a cold water tower or a refrigeration air conditioning unit.
Optionally, as shown in fig. 1 and 2, the temperature reducing device 10 for electrical equipment of this embodiment further includes a partition plate 14 and a sealing plate 13, where the partition plate 14 is connected between the bottom of the chassis 1 and the bottom of the electrical equipment on the lowest side of the plurality of electrical equipment 4; the sealing plate 13 is connected between the top of the case 1 and the top of the uppermost electrical equipment of the plurality of electrical equipment 4; the sealing plate 13, the plurality of electrical devices 4, and the partition plate 14 collectively partition the interior of the cabinet 1 into the cold air passage 11 and the hot air passage 12. In fig. 1, it can be seen that the left and right sides of the plurality of electrical devices 4 have the same size as the width of the enclosure 1, and meanwhile, the top electrical device of the plurality of electrical devices 4 is separated from the top of the enclosure 1 by a sealing plate 13, and the bottom electrical device of the plurality of electrical devices 4 is separated from the bottom of the enclosure 1 by a partition plate 14, so that the sealing plate 13, the plurality of electrical devices 4 and the partition plate 14 jointly separate the interior of the enclosure 1 into a cold air channel 11 located in front of the plurality of electrical devices 4 and a hot air channel 12 located behind the plurality of electrical devices 4.
In addition, for a specific arrangement mode, the upper end of the sealing plate 13 may be connected with the top of the case 1, and the lower end of the sealing plate 13 may be connected with the top of the electrical equipment 4 located at the uppermost side; and the lower end of the partition plate 14 is connected with the bottom of the case 1, the upper end of the partition plate 14 is connected with the bottom of the electrical equipment located at the bottommost side, the sealing plate 13 is vertically arranged, the partition plate 14 is obliquely arranged, and the end of the partition plate 14 connected with the electrical equipment is arranged closer to the front side than the end connected with the bottom of the case 1. The partition 14 arranged in this way enables better guidance of the cold air. In addition, optionally, the sealing plate 13 is a sheet metal part, and is connected to the top of the chassis 1 by welding, and the lower end of the partition plate 14 is connected to the bottom of the chassis 1 by welding.
The cold air passage 11 and the hot air passage 12 may be formed in other manners. For example, the uppermost electrical device of the electrical devices 4 may be directly contacted with the top of the cabinet 1, the lowermost electrical device of the electrical devices 4 may be directly contacted with the bottom of the cabinet 1, and the cooling air passage 11 and the heating air passage may be defined in the cabinet 1 by using the electrical devices 4.

The flow equalizing plate 15 is provided in the above scheme to equalize the flow of the relatively concentrated cold air entering from the air inlet 16 of the chassis, so that the cold air is uniformly distributed, the uniformity of the cooling capacity of the electrical equipment in each direction is ensured, and the heat dissipation effect is improved. The plate surface direction of the flow equalizing plate 15 and the air flow direction of the cold air channel 11 form an included angle, which means that the plate surface direction of the flow equalizing plate 15 is not parallel to the air flow direction of the cold air channel 11, so that when the air flow contacts the plate surface of the flow equalizing plate 15, the air flow can be uniformly dispersed along the plate surface of the flow equalizing plate 15 and passes through the air holes formed in the flow equalizing plate 15, and thus, the cold air which is relatively gathered is uniformly distributed.
The flow equalizing plate 15 can be selectively arranged in the case at a position close to the case air inlet 16, for example, directly above the case air inlet 16 and perpendicular to the air flow direction of the cold air channel 11, and one end of the flow equalizing plate 15 is connected with the front side wall of the case 1, and the other end is connected with the bottom end of the electrical equipment located at the lowest side.
In order to further increase the amount of the cool air entering the cool air passage 11, the number of the chassis air inlets 16 may be 3, as shown in fig. 4, and the 3 chassis air inlets 16 may be disposed to be distributed on the bottom wall of the chassis 1, which also facilitates the cool air to be spread evenly on the chassis 1. Specifically, on one hand, the uniformity of cold air distribution can be ensured, and on the other hand, the waste of cold energy caused by overlarge air flow of one air inlet can be conveniently prevented.
In the electrical equipment cooling device 11, a lot of dust can be accumulated in the case 1 after long-time use, the electrical equipment 4 in the case 1 is more, the cleaning is very difficult, and the dust accumulated for a long time can cause the electrical equipment 4 to generate heat, influence the heat dissipation effect and influence the running speed of the electrical equipment 4. It is therefore necessary to provide the electrical equipment cooling device 11 with a dust removing device.

In the above solution, the dust filtering net 51 is arranged between the dust box air inlet 52 and the dust box air outlet 53. Therefore, when the hot air having undergone heat exchange with the electric appliance 4 enters the dust box 1 from the dust box inlet 52, the dust and the like contained therein are filtered through the dust filter net 51, and the filtered air is returned to the refrigeration equipment 2 through the dust box outlet 53 and the refrigeration equipment inlet 22.
