DETAILED DESCRIPTION

As shown in FIG. 1 , FIG. 1 is a structural schematic diagram of an implementation of a heat exchange device for a power exchange cabinet proposed in the present utility model.

1 , the utility model proposes a heat exchange device for a power exchange cabinet, which is used to dissipate heat for a battery pack 11 in a power exchange cabinet 1, and includes: a plurality of columns 2 vertically arranged in the power exchange cabinet 1, a plurality of beams 3 vertically connected to the side walls of the columns 2, a plurality of boxes 4 installed on the beams 3, and a liquid cooling device 5. The beams 3 and the columns 2 are provided with flow channels 6 that are interconnected. A heat conducting plate 7 is installed on the inner bottom of the box 4. One end of the heat conducting plate 7 penetrates the box 4 and the side walls of the beam 3 and extends into the flow channel 6 of the beam 3. The flow channel 6 is connected to a port of the liquid cooling device 5, so that the cooling liquid in the liquid cooling device 5 can circulate in the flow channel 6.

During the specific working process of the heat exchange device of this embodiment, the power exchange cabinet 1 to be used is placed in the required working area, and the battery pack 11 to be used is placed in the box 4 in the power exchange cabinet 1. When the battery pack 11 is working, the liquid cooling device 5 starts to work, and the refrigerant is transported out from the output end, flows into the flow channel 6 in the beam 3 through the flow channel 6 in the column 2, and finally enters the liquid cooling device 5 from the input end of the liquid cooling device 5, providing a complete circulation route for the coolant. When the coolant passes through the flow channel 6 in the beam 3, the heat generated by the battery pack 11 in the box 4 is transferred to the inner wall of the flow channel 6 through the heat conduction plate 7, and the heat will be absorbed by the coolant, thereby cooling the heat conduction plate 7, and cooling the temperature in the box 4 and the outer wall temperature of the battery pack 11.

Based on the power swap cabinet 1, the present application opens a flow channel 6 in the columns 2 and the beams 3 inside the power swap cabinet 1, and connects the flow channel 6 with the liquid cooling device 5, so that the coolant of the liquid cooling device 5 can flow in the columns 2 and the beams 3, thereby saving the internal space of the power swap cabinet 1, and allowing the heat generated by the battery pack 11 to directly enter the coolant for heat exchange through the heat conduction plate 7, thereby greatly improving the efficiency of heat exchange of the battery pack 11.

Referring to Figures 2 and 3, in this embodiment, the heat exchange device specifically includes: four columns 2 arranged in a rectangular array in the power exchange cabinet 1, and a number of beams 3 are vertically connected at equal intervals between the side walls of two adjacent columns 2 on the left and right.

The crossbeam 3 is provided with a groove adapted to install and place the box 4 , and the side walls of the box 4 are connected to the upper end of the crossbeam 3 through a 90-degree angle strip, thereby improving the firmness of the box 4 installed on the crossbeam 3 .

4 , in this embodiment, the heat conducting plate 7 specifically includes a heat conducting flat plate portion 8 installed on the inner bottom of the box body 4, an extension portion 9 connected to the end of the heat conducting flat plate portion 8, the extension portion 9 penetrates the box body 4 and the side wall of the beam 3 and extends into the flow channel 6 of the beam 3. On the basis that the front and rear ends of the box body 4 are respectively installed on the first beam and the second beam, the two ends of the heat conducting flat plate portion 8 are connected to the extension portion 9 to synchronously dissipate heat at both ends of the heat conducting plate 7.

The portion of the extension portion 9 extending into the flow channel 6 of the cross beam 3 is in a ring shape, which increases the contact surface between the extension portion 9 and the coolant and improves the cooling efficiency of the heat conducting plate 7 .
