[0057] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 2 The up and down directions are consistent with the left and right directions mentioned below. Figure 2 The left and right directions are consistent with the Figure 2 The projection direction itself is consistent.

[0058] like Figures 1 to 5 As shown, this embodiment provides an air conditioner, including a housing 11, a partition 12, a heat exchanger 13, and a fan 14. The fan 14 is a cross-flow fan, and the heat exchanger 13 is a fin heat exchanger 13. The fin heat exchanger 13 has a liquid inlet pipe 132 and a liquid outlet pipe 133. The liquid inlet pipe 132 and the liquid outlet pipe 133 can be used to realize the circulation and transportation of the refrigerant. The housing 11 has a cavity 15, an air inlet 1131, and an air outlet 1132. The cavity 15 is the space inside the housing 11. The air inlet 1131 and the air outlet 1132 are opened on the side of the housing 11. The cavity 15 is connected to the outside of the housing 11 through the air inlet 1131 and the air outlet 1132 to realize the circulation of air and then realize heat exchange.

[0059] The partition 12 is installed in the cavity 15 and divides the cavity 15 into a first air cavity 151 and a second air cavity 152. The partition 12 is provided with a ventilation hole 121. The ventilation hole 121 is a flow channel, that is, the partition 12 divides the cavity 15 and forms a flow channel. At the same time, the partition 12 can withstand pressure and also act as a heat transfer surface. The first air cavity 151 and the second air cavity 152 are connected only through the ventilation hole 121. The first air cavity 151 is connected to the outside of the housing 11 through the air inlet 1131, and the second air cavity 152 is connected to the outside of the housing 11 through the air outlet 1132. The heat exchanger 13 is installed in the first air cavity 151, and the fan 14 is installed in the second air cavity 152. The fan 14 has an air inlet 141 located at the ventilation hole 121 and connected to the first air cavity 151 through the ventilation hole 121, and an air outlet 142 connected to the second air cavity 152. When the air conditioner is working, the fan 14 is started, and a negative pressure is formed at the air inlet 141, so that the external air enters the first air cavity from the air inlet 1131. 151 and exchanges heat with the heat exchanger 13 in the first air cavity 151. By setting the partition, the air can fully exchange heat with the heat exchanger after entering the first air cavity, and will not be directly sucked away by the air intake port 141. The heat exchange efficiency is high. The air after heat exchange directly enters the air intake port 141 from the ventilation hole. The heat transfer and heat transfer of the partition are utilized to further improve the heat exchange efficiency. The air after heat exchange enters the air intake port 141 of the fan 14 from the ventilation hole 121, and then the air is discharged from the exhaust port 142. Finally, the air after heat exchange is discharged to the outside of the air conditioner from the air outlet 1132 to achieve cooling or heating.

[0060] The fan 14 generates suction force by rotating the blades. The air inlet 141 of the fan 14 draws air in a direction parallel to the rotation axis of the blades, and the air outlet 142 of the fan 14 exhausts air in a direction perpendicular to the rotation axis of the blades. The air inlet 141, the partition 12, and the heat exchanger 13 are arranged in sequence along the rotation axis of the blades.

[0061] In addition, when the heat exchanger 13 is clogged with microorganisms or dust, the fan 14 itself has a weak ability to resist negative pressure. If the distance between the air inlet 141 and the heat exchanger 13 is too small, the fan 14 will not draw air evenly. If the distance between the air inlet 141 and the heat exchanger 13 is too far, the fan 14 will not draw air well. Therefore, the distance D between the air inlet 141 and the heat exchanger 13 of the utility model is greater than or equal to 30 mm and less than or equal to 60 mm. The distance D is the distance along the rotation axis of the blade, that is, Figure 2 The projection direction is preferably 38 mm to 50 mm. This avoids uneven air suction caused by the air suction port being too small and affecting the heat exchange performance, and also avoids poor air suction effect caused by the air suction port being too large and causing the air suction effect of the fan to deteriorate, so that the air suction of the fan 14 is more uniform and has a better air suction effect, ensuring the normal air discharge of the fan, reducing the energy consumption of the air conditioner, and improving the comfort of the user.

The inclined volute tongue 11192 is in a rotating shape, so that the aerodynamic performance of the flow field near the fan 14 is stronger, and the flow field near the inclined volute tongue 11192 is gradually deformed in a stepped shape, which increases the stability of the swirl flow and improves the resistance of the air supply. The machine plate 16 is connected to the inner plate surface 1116 of the base 111 by means of threaded fasteners, and the fan 14 is located in the air duct 1119. Since the height difference between the motor and the blades of the ultra-thin centrifugal fan 14 is small, in order to facilitate the installation of the centrifugal fan 14, the utility model further includes a circular machine plate 16, which is a sheet metal part and has four circular holes. The fan 14 has a mounting column 143, and a connecting hole column is provided on the mounting column 143. The diameter of the circular hole on the machine plate 16 is slightly larger than the diameter of the connecting hole column. The machine plate 16 is first mounted on the mounting column 143 of the fan 14 by threaded connection with the connecting hole column using threaded fasteners. Four nut columns 161 are also riveted on the machine plate 16, and a groove is provided on the base 111. The third sheet metal 20 is embedded in the groove. After the machine plate 16 is pre-installed on the fan 14, the third sheet metal 20 is connected to the nut columns 161 on the machine plate 16 using threaded fasteners, so as to facilitate the installation of the fan 14.

[0071] Optionally, the inclined volute tongue 11192 is an inclined gradually sloped structure with an inclined ridge. The inclined volute tongue 11192 converts more kinetic energy generated by the fan 14 into static pressure, ensures that air flows out of the air outlet 1132 evenly, reduces turbulence and eddy currents, and thus improves the aerodynamic performance of the fan 14. When viewed along the air outlet 1132, the inclination angle α of the inclined volute tongue 11192 is 21-26°, and when viewed along the air inlet 1131, the angle γ between the inclined volute tongue 11192 and the horizontal line is 34-38°. The inner wall surface of the air duct 1119 is the inner side, and the outer wall surface of the air duct 1119 is the outer side. The inner and outer inclination slopes β are 45-47°.

[0072] Furthermore, there are at least two air ducts 1119, and the two air ducts 1119 are asymmetrically arranged. A fan 14 is installed in each of the two air ducts 1119, and the air outlets 11191 of the two air ducts 1119 face in opposite directions to improve the air heat exchange efficiency.

[0073] Furthermore, the edge of the ventilation hole 121 of the partition 12 extends along the axial arc of the rotating shaft of the fan 14, thereby improving the flow guidance efficiency.

[0074] like Fig.15 As shown, in one embodiment, the housing 11 further includes a bottom plate 116 and a filter. The front panel 113 and the base 111 are both connected to the bottom plate 116, and the bottom plate 116 is simultaneously connected to the front panel 113 and the base 111 by threaded fasteners. The filter covers all air inlets 1131, and the filter blocks some floccules or mosquitoes in the air, and also plays a dust-proof role, avoiding blockage of the fin heat exchanger 13, effectively reducing the formation of dirt, dust blockage, etc. on the heat exchanger 13, thereby avoiding affecting the fan 14. The bottom plate 116 is located below the front panel 113 and the base 111, and a replacement port 117 connected to the first air cavity 151 is formed between the bottom plate 116 and the front end surface of the front panel 113. The filter is installed in the first air cavity 151 from the replacement port 117 and covers the air inlet 1131, which is convenient for replacing the filter and avoiding the influence of the air conditioner operation due to the blockage of the filter. The replacement port 117 is located below the housing 11, and the filter can be pulled out for replacement. When the filter is installed in the first air cavity 151 from the replacement port 117, it can be quickly installed on the front panel 113 by snapping or engaging with the bayonet.

[0075] Furthermore, the bottom plate 116 and the folded edge of the bottom plate 116 are threadedly connected to the front panel 113 to form a heat exchange tube hole, the bottom plate 116 is connected to the base 111, and the bottom plate 116 is provided with a first tube hole for the drainage joint 114 to pass through and a second tube hole for the liquid inlet pipe 132 and the liquid outlet pipe 133 of the heat exchanger 13 to pass through.

[0076] It can be understood that the threaded fasteners in the above embodiments are screws, bolts, studs, etc. In addition, rivets and other connecting parts can also be used instead of threaded fasteners.
