In an embodiment of the present invention, the air outlet structure 30 includes a positive air outlet structure 31, the positive air outlet structure 31 is disposed at the upper end of the casing 10 and has a positive air outlet 3111 communicated with an air duct, and the air inlet structure 20 is disposed at the lower end of the casing 10 and communicated with an air duct; the casing 10 is further provided with a fan 70 and a heat exchanger 90, the fan 70 is arranged between the air inlet structure 20 and the positive air outlet structure 31, the heat exchanger 90 comprises a double-row pipe heat exchanger 93 and at least one single-row pipe heat exchanger 95, the double-row pipe heat exchanger 93 and the single-row pipe heat exchanger 95 are both arranged below the fan 70 and are both arranged facing the air inlet structure 20, and the at least one single-row pipe heat exchanger 95 is arranged at one end of the double-row pipe heat exchanger 93, which is far away from the fan 70;
air enters the air channel from the air inlet structure 20, exchanges heat through the double-row pipe heat exchanger 93 and the single-row pipe heat exchanger 95, and is blown out from the fan 70 to the positive air outlet structure 31.
The heat exchanger 90 of the cabinet air conditioner 100 in the technical scheme of the invention comprises a double-row pipe heat exchanger 93 and a single-row pipe heat exchanger 95, the double-row pipe heat exchanger 93 has double-row heat exchange pipes for heat exchange, and the heat exchange effect is better than that of the single-row pipe heat exchanger 95 only having single-row heat exchange pipes, but due to the design of the double-row heat exchange pipes, the thickness of the double-row pipe heat exchanger 93 is larger than that of the single-row pipe heat exchanger 95, so the air inlet resistance at the position of the double-row pipe heat exchanger 93 is larger than that at the position of the single-row pipe heat exchanger 95. Locate one side that double row pipe heat exchanger 93 deviates from fan 70 with a single bank of tubes heat exchanger 95, because double row pipe heat exchanger 93 is nearer apart from fan 70, this single row pipe heat exchanger 95 is far away from fan 70, fan 70 is stronger than the power of inhaling of this single row pipe heat exchanger 95 department to the power of induced drafting of double row pipe heat exchanger 93 department, thereby make the intake of double row pipe heat exchanger 93 and this single row pipe heat exchanger 95 department equal, consequently, it is more even that the air inlet effect is more even when making this cabinet air conditioner 100 have better heat exchange effect, and this single row pipe heat exchanger 95 is far away from fan 70, fan 70 is less to the power of induced drafting of this single row pipe heat exchanger 95 department, make the noise that this single row pipe heat exchanger 95 department air inlet produced less, thereby make this cabinet air conditioner 100's tone quality better.
Referring to fig. 2-5, in one embodiment of the present invention, the height of the double row tube heat exchanger 93 is equal to the height of the single row tube heat exchanger 95. Because the heat transfer effect of double-row tube heat exchanger 93 is superior to the heat transfer effect of single-row tube heat exchanger 95, but the weight of double-row tube heat exchanger 93 with the same height is bigger than that of single-row tube heat exchanger 95, therefore, the height of double-row tube heat exchanger 93 is set to be equal to the height of single-row tube heat exchanger 95, the weight is lighter when making this cabinet air conditioner 100 have a better heat transfer effect, the assembly is convenient, and the cost is lower.
Referring to fig. 6, 7 and 8, in one embodiment of the present invention, the height of the double row tube heat exchanger 93 is twice the height of the single row tube heat exchanger 95. Because the double-row heat exchanger 93 has better heat exchange effect, but the air inlet resistance is larger, the height of the double-row pipe heat exchanger 93 is twice as high as the single-row pipe heat exchanger 95, so that the air inlet volume at the position of the double-row pipe heat exchanger 93 is larger, the heat exchange effect of the cabinet air conditioner 100 is better, and the air inlet volume is more uniform.
With reference to fig. 3 and 9, the heat exchanger 90 in fig. 3 is replaced by the heat exchanger 90 in fig. 9 to obtain another embodiment of the present invention, and with reference to fig. 9 to 11 in particular, the side of the double-row tube heat exchanger 93 facing the fan 70 is further provided with a single-row tube heat exchanger 95. Because the air inlet resistance of the single-row tube heat exchanger 95 is small, but the air inlet amount is large, and the heat exchange effect of the double-row tube heat exchanger 93 is good, but the air inlet resistance is large, therefore, in order to better combine the advantages of the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95, in this embodiment, a structure that the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95 are arranged in a staggered manner is adopted, specifically, one single-row tube heat exchanger 95 is respectively arranged above and below the double-row tube heat exchanger 93, and is butted with the end portion of the double-row tube heat exchanger 93. The arrangement of this structure makes cabinet air conditioner 100 have good heat transfer effect simultaneously, has the advantage that the intake is big concurrently.
Specifically, in this embodiment, the height of the double-row tube heat exchanger 93 is equal to the height of each single-row tube heat exchanger 95, and the heights of the double-row tube heat exchanger 93 and the two single-row tube heat exchangers 95 may also be set to be unequal according to specific requirements.
In the embodiment of the present invention, one end of each single-row tube heat exchanger 95 is abutted against one end of the double-row tube heat exchanger 93. The air inlet structure and the air outlet structure are tightly connected at the longitudinal position, so that the heat exchange of the air entering the air inlet structure 20 is more comprehensive.
It is understood that, in other embodiments of the present invention, other connecting structures may be further disposed between the single-row tube heat exchanger 95 and the double-row tube heat exchanger 93 to connect the two heat exchangers, for example, a gap is formed between the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95, the gap is covered by a cover plate, and the cover plate is fixedly connected to the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95, so that not only the purpose of connecting the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95 can be achieved, but also the gap between the two can be sealed, and the heat exchanging effect of the heat exchanger 90 is better.

Because the air exchanges heat along the thickness direction of the double-row tube heat exchanger 93, the two rows of heat exchange tubes 911 of the double-row tube heat exchanger 93 are arranged in a staggered manner along the thickness direction, so that the air entering the double-row tube heat exchanger 93 can exchange heat more sufficiently, and the heat exchange effect of the cabinet air conditioner 100 is better.
It will be appreciated that the single row tube heat exchanger 95 includes a row of vertically disposed heat exchange tubes 911.
Referring to fig. 5, 7 and 10, in the embodiment of the present invention, the heat exchanger 90 further includes a connecting plate 92, and the connecting plate 92 is fixedly connected to the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95 in a vertical direction. The connection plate 92 fixes the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95 together, so that the heat exchanger 90 is more stable.
Each double-row pipe heat exchanger 93 and each single-row pipe heat exchanger 95 are provided with two side end faces arranged along the vertical direction, heat exchange pipes 911 in each double-row pipe heat exchanger 93 and each single-row pipe heat exchanger 95 are arranged along the horizontal direction and penetrate through the two side end faces, each heat exchange pipe 911 is of a bending structure and is provided with a bending end 9 (marked) and a joint end (marked), and the bending end and the joint end extend out of the two side end faces of each double-row pipe heat exchanger 93 (the two side end faces of each single-row pipe heat exchanger 95) respectively. The connecting plate 92 connects the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95 along one side end face which is aligned with each other in the vertical direction, and the side end face is the side end face where the joint end of the heat exchange tube 911 is located. Specifically, referring to fig. 5, the connection plate 92 has a plurality of connection holes 921, the connection holes 921 are matched with the joint ends of the heat exchange tubes 911 of the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95, and each joint end has two joints (not labeled). Each connector passes through a corresponding connection hole 921, thereby realizing the connection of the connection plate 92 to the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95.
It is understood that when the cabinet air conditioner 100 has two or more single-row tube heat exchangers 95, the structure and connection structure of the connection plate 92 are similar to the above structure, and thus, the detailed description thereof is omitted.
With further reference to fig. 5, the heat exchanger 90 further includes a mounting bracket 94 secured to the housing 10, the double row tube heat exchanger 93 and the single row tube heat exchanger 95 being captured within the mounting bracket 94, and the connecting plate 92 being secured to the mounting bracket 94.
Referring to fig. 1 and 2, the air intake structure 20 is disposed around the circumference of the casing 10, and the double-row tube heat exchanger 93 and the single-row tube heat exchanger 95 are both disposed in a ring shape.
