Referring to fig. 2, 3 and 4, the plurality of heat exchange tube sets 11 are integrally connected and fixed by the connection structure 4. Because the heat exchanger 1 includes a plurality of heat exchange tube sets 11, but only part of the heat exchange tube sets 11 extend below to form the supporting part 31, the end of the heat exchange tube set 11 without the supporting part 31, which is close to the water pan 2, does not contact the water pan 2, and in order to keep the suspended state, the heat exchange tube set 11 does not fall into the water pan 2, and the heat exchange tube sets 11 are connected and fixed into a whole through the connecting structure 4. The utility model discloses smallpox machine. The plurality of heat exchange tube sets 11 of the heat exchanger 1 are detachably connected into a whole, so that the heat exchange tube sets 11 can be conveniently detached and assembled. The connecting structure 4 comprises a connecting piece 41 fixedly connected with all the heat exchange tube sets 11, the connecting piece 41 is attached to the side wall of the supporting plate 112, and the connecting piece 41 is fixedly connected with the supporting plate 112 of the heat exchange tube sets 11 positioned at two opposite sides of the heat exchanger 1 by using screws 42; the connecting piece 41 is provided with a fixing hole at a position corresponding to the heat exchange tube 111 of the heat exchange tube group 11 in the middle of the heat exchanger 1, and the heat exchange tube 111 passes through the fixing hole, so that the connecting piece 41 is fixedly connected with the heat exchange tube group 11 in the middle.

Each heat exchange tube group 11 includes a plurality of heat exchange tubes 111, the plurality of heat exchange tubes 111 are arranged at intervals, and a gap is left between two adjacent heat exchange tubes 111, so that an air flow can pass through the gap between the heat exchange tubes 111. In order to enable the air flow to exchange heat with each heat exchange tube 111 of the plurality of heat exchange tube sets 11 better, two adjacent gaps between two adjacent heat exchange tube sets 11 are arranged in a staggered manner, so that the contact area and the heat exchange time of the air flow and the heat exchanger 1 are increased, and the heat exchange capacity of the heat exchanger 1 is enhanced.

The heat exchanger 1 includes a plurality of heat exchange tube sets 11, and a plurality of heat exchange tube sets 11 are stacked along the wind channel extending direction of the ceiling fan, and each heat exchange tube set 11 has arranged a plurality of heat exchange tubes 111 along the vertical direction. In order to increase the path stroke of the refrigerant flowing in the heat exchanger 1, the residence time of the refrigerant in the heat exchange tube 111 is increased, the heat exchange between the refrigerant and the heat exchange tube 111 is enhanced, and the heat exchange efficiency of the heat exchanger is further improved. In the embodiment of the present invention, as shown in fig. 3 and 5, the heat exchanger 1 further includes an elbow 12, the elbow 12 is communicated with the at least two heat exchange tubes 111, so as to communicate the at least two heat exchange tubes 111 to form a refrigerant passage; the refrigerant flows into the refrigerant passage from one of the heat exchange tubes 111 constituting the refrigerant passage, passes through the plurality of heat exchange tubes 111 communicating with each other, and is discharged.

It should be noted that the refrigerant refers to a heat exchange medium adopted in the heat exchanger 1, and optionally, the refrigerant may be freon, alkane, ammonia gas, or carbon dioxide. The refrigerant passage is a pipeline for circulating refrigerant, which is formed by a plurality of mutually communicated heat exchange sensors 111; when a refrigerant passage has a flow dividing design, that is, as shown in fig. 2 and 4, one heat exchange tube 111 communicates with two heat exchange tubes 111 at the same time, one refrigerant passage includes two branches, and the refrigerant flows through the same number of heat exchange tubes 111 regardless of which branch the refrigerant flows. If the refrigerant passage is too short, the refrigerant cannot be sufficiently heat-exchanged with the heat exchange tube 111 and is discharged out of the heat exchanger, so that the heat exchange effect of the heat exchanger 1 is affected; if the refrigerant passage is too long, the temperature difference between the refrigerant and the heat exchange tube 111 becomes smaller and smaller along with the flowing process of the refrigerant, and the heat exchange effect between the heat exchange tube 111 behind the refrigerant passage and the refrigerant is poor, so that the heat exchange effect of the heat exchanger 1 is affected. In the embodiment of the present invention, when the refrigerant passes through four heat exchange tubes 111 in the heat exchanger 1, the heat exchange efficiency of the heat exchanger 1 is higher.
