When the heat exchange device is in operation, heat exchange can be performed through the medium between the first heat exchange core 3 and the second heat exchange core 4. The first fan 11 sends external air to the air exchange chamber from the position where the horizontal cross section is large, and when the air flows to the first heat exchange core 3, the horizontal cross section decreases, so that the flow speed of the air is increased, and the heat exchange effect of the first heat exchange core 3 and the air is accelerated. The second fan 12 sends the air in the electrical cabinet to the heat exchange chamber from the position where the horizontal cross section is large, and when the air flows to the second heat exchange core 4, the horizontal cross section decreases, so that the flow speed of the air is increased, and the heat exchange effect of the second heat exchange core 4 and the air is accelerated, thereby further improving the heat exchange efficiency of the heat exchange device.

[0025] Preferably, in the embodiment, the heat exchange chamber is located in the electrical cabinet during installation, and is used to absorb the hot air in the electrical cabinet and then re-deliver the air to the electrical cabinet after heat exchange and cooling by the second heat exchange core 4. The second fan 12 is located above the heat exchange chamber, so that the heat in the electrical cabinet can be better absorbed, and the heat exchange effect of the electrical cabinet is improved.
