In the present utility model, the heat exchanger 2 is a passive heat exchanger, which can realize heat exchange between the heat absorbing end 21 and the heat releasing end 22 without providing a compressor, so that the heat absorbing end 21 continuously absorbs heat in the indoor side air duct 61, and the heat releasing end 22 continuously releases heat to the outdoor side air duct 62. Specifically, the heat-absorbing end 21 of the heat exchanger 2 stores a first heat-exchanging medium, the heat-releasing end 22 stores a second heat-exchanging medium, the heat exchanger 2 is further provided with a first flow passage communicated with the inside of the heat-absorbing end 21 and a second flow passage communicated with the inside of the heat-releasing end 22, the first flow passage and the second flow passage are in contact with each other in a region between the heat-absorbing end 21 and the heat-releasing end 22 in the heat exchanger 2, so that the first heat-exchanging medium in the first flow passage and the second heat-exchanging medium in the second flow passage quickly exchange heat, the heat-absorbing end 21 continuously absorbs heat in the indoor air flow 300 in the indoor air passage 61, and the heat-releasing end 22 continuously releases heat in the outdoor air flow 400 in the outdoor air passage 62, thereby achieving the effect of passive heat exchange. Compared with air conditioning heat exchange equipment adopting a compressor, the heat exchanger 2 is efficient and energy-saving, has low noise, and is particularly suitable for a scene of cooling indoor air by using an outdoor low-temperature environment and keeping the indoor environment clean.

In this embodiment, referring to fig. 1, the dashed arrow represents the airflow direction, wherein the indoor airflow 300 flows into the indoor air duct 61 from the indoor air inlet 11 under the driving of the indoor air blower set 4, flows through the heat absorbing end 21 of the heat exchanger 2, is absorbed in heat and cooled, and flows into the room from the indoor air outlet 12, so as to cool the indoor air. The outdoor air flow 400 flows into the outdoor air duct 62 under the action of the outdoor side fan unit 5, absorbs heat and heats up after flowing through the heat release end 22 of the heat exchanger 2, and flows out from the outdoor air outlet 14.
