In this embodiment, the heat exchange wall 1 may be disposed according to the original spatial distribution in the machine room, and the space in the machine room may be divided into a plurality of sub-areas by using the heat exchange wall 1.
The heat exchange wall body 1 in the embodiment can be a single-wall structure, and the single-wall structure can be a linear wall or an arc wall; in addition, the heat exchange wall 1 may also be configured as a special-shaped structure formed by splicing a plurality of single walls, such as a "Y" shaped structure, an "X" shaped structure, and the like, wherein the plurality of single walls in the special-shaped structure wall may be communicated with each other. As shown in fig. 2, when the heat exchange wall 1 is a single-wall structure, the space in the machine room can be divided into two adjacent sub-areas by using the same heat exchange wall 1; if the heat exchange wall body 1 is in a Y-shaped structure, the space in the machine room can be divided into three sub-areas; as shown in fig. 3, if the heat exchange wall 1 is configured as an "X" shaped structure, the space in the machine room can be divided into four sub-areas.
As shown in fig. 1, an external circulation pipeline 3 and an internal circulation air duct 2 are embedded in the heat exchange wall 1, wherein the number of the external circulation pipelines 3 is at least one, and can be adjusted according to the arrangement rule and the number of the internal circulation air ducts 2; the external circulation can be realized by utilizing the external circulation pipeline 3 and the external circulation subsystem 5 communicated with the external circulation pipeline 3, and the internal circulation air duct 2 in the heat exchange wall body 1 is subjected to heat exchange by utilizing the external circulation. The number of the internal circulation air ducts 2 in the heat exchange wall 1 is the same as that of the sub-areas. And inner loop wind channel 2 and outer circulating line 3 all can be equipped with the aluminium alloy pipeline, and the aluminium alloy pipeline has better thermal diffusivity relatively to accelerate heat exchange efficiency, simultaneously inner loop wind channel 2 and outer circulating line 3 all can be established to snakelike structure, and the flow time of multiplicable gas or liquid through crooked pipeline, thereby it is long when increasing the cooling refrigeration, can reach better cooling refrigeration effect. And the internal circulation air duct 2 is tightly attached to the end surface of the external circulation duct 3, the end surface of the cross section of the external circulation duct 3, which is right opposite to the internal circulation air duct 2, is arranged to be an arc-shaped end surface matched with the cross section of the internal circulation air duct 2, so that the contact area between the external circulation duct 3 and the internal circulation air duct 2 is increased, and the heat exchange effect of the external circulation duct is improved.
