Each of the second microchannel tubes 123 may be a flat multiport tube extending in the height direction of the second coil 120 (i.e., the height direction D2 of the microchannel heat exchanger 100 in this embodiment).

The microchannel heat exchanger 100 of the present application also includes a first inlet connector 130A and a first outlet connector 140A, and a second inlet connector 130B and a second outlet connector 140B. Wherein the first inlet connector 130A is fluidly connected to the first inlet header 111 of the first coil 110 and the first outlet connector 140A is fluidly connected to the first outlet header 112 of the first coil 110. A second inlet connector 130B is fluidly connected to the second inlet header 121 of the second coil 120 and a second outlet connector 140B is fluidly connected to the second outlet header 122 of the second coil 120.
The microchannel heat exchanger 100 of the present application also includes a first inlet conduit 150A and a first outlet conduit 160A, and a second inlet conduit 150B and a second outlet conduit 160B.

The microchannel heat exchanger 100 of the present application has a first side and a second side along the length direction D1 of the microchannel heat exchanger 100. The first inlet connector 130A, the first outlet connector 140A, the second inlet connector 130B, and the second outlet connector 140B are all located on a first side of the microchannel heat exchanger 100 (the left side of the paper as viewed in fig. 1). By arranging the first inlet connector 130A, the first outlet connector 140A, the second inlet connector 130B and the second outlet connector 140B on the same side of the microchannel heat exchanger 100 in the length direction D1, the inlet and outlet pipelines of the microchannel heat exchanger 100 are collected together and enter and exit from the same side, so that the application pipeline design of the microchannel heat exchanger 100 can be simplified, and the microchannel heat exchanger 100 can better keep the balance of internal refrigerant distribution and reduce the design difficulty of corresponding refrigerant distribution structures.
As shown in fig. 5 and 6, the first coil 110 and the second coil 120 of the microchannel heat exchanger 100 of the present application are offset from each other in the longitudinal direction of the microchannel heat exchanger 100 and are arranged in parallel with a partial overlap. That is, the first coil 110 and the second coil 120 are parallel to each other in the length direction of the microchannel heat exchanger 100, and there may be a partial overlap of the first coil 110 and the second coil 120 in the thickness direction of the microchannel heat exchanger 100. The terms "parallel" or "overlapping" as used herein are relative to the overall structure of the first coil 110 and the second coil 120.
As shown in fig. 6, in some embodiments, the first coil 110 and the second coil 120 have a height direction parallel to the height direction of the entire microchannel heat exchanger 100. Of course, the microchannel heat exchanger 100 of the present application is not so limited. In other embodiments, the height direction of the first coil 110 and the second coil 120 may be inclined to the height direction of the whole microchannel heat exchanger 100, so that the first coil 110 and the second coil 120 are parallel to each other and are inclined in the whole microchannel heat exchanger 100. Therefore, under the condition that the sectional area of the air conditioner is fixed, the height of the coil pipe can be higher, and the heat exchange area can be larger.
In some embodiments, the microchannel heat exchanger 100 of the present application is a two-pass heat exchanger. The microchannel heat exchanger 100 has a first end (e.g., an upper end or a lower end) and a second end (e.g., a lower end or an upper end) in a height direction of the microchannel heat exchanger 100. The first inlet header 111, the first outlet header 112, the first inlet connector 130A, the first outlet connector 140A and the second inlet header 121, the second outlet header 122, the second inlet connector 130B and the second outlet connector 140B are all located at a first end of the microchannel heat exchanger 100. In the illustrated embodiment of the present application, the first end of the microchannel heat exchanger 100 is the bottom of the microchannel heat exchanger 100 and the second end of the microchannel heat exchanger 100 is the top of the microchannel heat exchanger 100. Of course, in other embodiments of the present application, the first end of the microchannel heat exchanger 100 may be the top of the microchannel heat exchanger 100, and the second end of the microchannel heat exchanger 100 may be the bottom of the microchannel heat exchanger 100, without altering the spirit of the present application, and such equivalents or minor modifications will still fall within the scope of the claims appended hereto.
In some embodiments, a first inlet header 111 and a first outlet header 112 are located at the bottom of the first coil 110, and a second inlet header 121 and a second outlet header 122 are located at the bottom of the second coil 120. Since the first coil 110 and the second coil 120 are arranged in parallel with being offset from each other and partially overlapped in the length direction of the microchannel heat exchanger 100, the first inlet header 111, the first outlet header 112, the second inlet connector 130B, and the second outlet connector 140B may be arranged in the thickness direction of the microchannel heat exchanger 100, as shown in fig. 5 and 6. Furthermore, the second inlet connector 130B located on the far side and the first inlet header 111 of the first coil 110 located on the near side, and the second outlet connector 140B located on the far side and the first outlet header 112 of the first coil 110 located on the near side do not need to be arranged in the height direction along the microchannel heat exchanger 100, and therefore, the height of the first coil 110 located on the near side does not need to be reduced, and the second inlet connector 130B and the second outlet connector 140B located on the far side do not occupy the windward area of the first coil 110 located on the near side.
With further reference to fig. 5, there is a first gap 170A between the first inlet header 111 and the first outlet header 112 of the first coil 110, with one of the second inlet connector 130B and the second outlet connector 140B disposed in the first gap 170A between the first inlet header 111 and the first outlet header 112, i.e., one of the second inlet connector 130B and the second outlet connector 140B is located between the first inlet header 111 and the first outlet header 112 of the first coil 110. The other of the second inlet connector 130B and the second outlet connector 140B is arranged at one side of the first inlet header 111 or the second inlet header 121 in the thickness direction of the microchannel heat exchanger 100. In the illustrated embodiment of the present application, the second inlet connector 130B fluidly connected to the second inlet header 121 of the second coil 120 is located in the first gap 170A between the first inlet header 111 and the first outlet header 112 of the first coil 110, and the second outlet connector 140B fluidly connected to the second outlet header 122 of the second coil 120 is located on a side of the first outlet header 112 of the first coil 110 away from the first inlet header 111.
Referring to fig. 5, the first inlet header 111, the second inlet connector 130B, the first outlet header 112, and the second outlet connector 140B of the present application are arranged in order at the bottom of the first coil 110 in the thickness direction of the microchannel heat exchanger 100. As shown in fig. 5 and 6, the first inlet connector 130A, the second inlet connector 130B, the first outlet connector 140A, and the second outlet connector 140B of the present application are sequentially arranged in a thickness direction of the microchannel heat exchanger 100.
As shown in fig. 5, the header of the second inlet header 121 and the second outlet header 122, which communicates with one of the connectors, faces the first gap 170A, there is a second gap 170B between the second inlet header 121 and the second outlet header 122, and one of the first inlet header 111 and the first outlet header 112 faces the second gap 170B. In the illustrated embodiment of the present application, the second inlet header 121 of the second coil 120 is directly opposite the first gap 170A and the first outlet header 112 of the first coil 110 is directly opposite the second gap 170B.
The microchannel heat exchanger 100 of the present application can further reduce the overall thickness of the microchannel heat exchanger 100 by arranging the first coil 110 on the near side and the second coil 120 on the far side in parallel, which are offset from each other and partially overlap in the thickness direction of the microchannel heat exchanger 100, so that the second inlet connector 130B or the second outlet connector 140B on the far side can be arranged in the first gap 170A between the first inlet header 111 and the first outlet header 112 of the first coil 110 on the near side.
In some embodiments, the first coil 110 and the second coil 120 may be identical. The first coil 110 and the second coil 120 may have the same frontal area. Because the microchannel heat exchanger 100 of the present application can be constructed using the same microchannel tubes or coils, the structure and manufacturing process of the microchannel heat exchanger 100 can be simplified, and the cost can be reduced.
During operation of the microchannel heat exchanger 100, refrigerant first flows from the first inlet conduit 150A and the second inlet conduit 150B of the microchannel heat exchanger 100, through the first inlet connector 130A and the second inlet connector 130B, into the first inlet header 111 and the second inlet header 121, respectively, and then enters the first microchannel tube 113 of the first coil 110 and the second microchannel tube 123 of the second coil 120, respectively, from the bottom of the multi-coil microchannel heat exchange through the first microchannel tube 113 of the first coil 110 and the second microchannel tube 123 of the second coil 120, respectively, to the top of the multi-coil microchannel heat exchange, and then flows from the top of the multi-coil microchannel heat exchange down to the bottom in the height direction D2 of the multi-coil microchannel heat exchange. As the refrigerant flows within the first and second microchannel tubes 113 and 123, the refrigerant exchanges heat with a fluid (e.g., air) outside the first and second microchannel tubes 113 and 123, respectively. After exchanging heat with an external fluid, the refrigerant exits the first and second microchannel tubes 113 and 123, respectively, then flows into the first and second outlet headers 112 and 122, respectively, and finally flows into the first and second outlet conduits 160A and 160B through the first and second outlet connectors 140A and 140B, respectively. Thereby, the process of heat exchange is completed.
The microchannel heat exchanger 100 described above is illustrated with the inlet and outlet piping disposed at the bottom as an example. Of course, in other embodiments, the microchannel heat exchanger 100 may have the inlet and outlet piping disposed at the top, which does not alter the spirit of the present application, and such equivalent or minor modifications will still fall within the scope of the claims appended hereto.
The micro-channel heat exchanger 100 can make full use of the sectional area of the air conditioner, increase the windward area of the coil pipe and reduce the whole thickness of the micro-channel heat exchanger 100 and simplify the design of the pipeline connected with the heat exchanger on the basis of reducing the production and manufacturing difficulty of the heat exchanger and the working medium distribution design difficulty.
As shown in fig. 1 and 2, in some embodiments, the microchannel heat exchanger 100 of the present application further comprises a baffle mounting bracket 180, and the baffle mounting bracket 180 may be disposed adjacent to the first coil 110 and the second coil 120. In one embodiment, the microchannel heat exchanger 100 of the present application is provided with a separator mounting bracket 180 on both sides along the thickness direction D3 of the microchannel heat exchanger where the first coil 110 and the second coil 120 are adjacent.
In some embodiments, the microchannel heat exchanger 100 of the present application may further comprise an optional baffle 190 for conditioning the wind field, the optional baffle 190 being selectively mountable to the baffle mounting bracket 180 along at least one side of the thickness direction D3 of the microchannel heat exchanger. Therefore, in the thickness direction (front-back direction of the paper as shown in fig. 1) D3 of the microchannel heat exchanger 100, both the first coil 110 in front of the paper and the second coil 120 in back of the paper have good heat exchange capability, and uniform heat exchange is maintained. As shown in fig. 7 and 8, in one embodiment, an optional spacer plate 190 may be mounted to the spacer plate mounting bracket 180 along one side of the microchannel heat exchanger in the thickness direction D3. In another embodiment, as shown in FIG. 9, an optional spacer plate 190 may be mounted to the spacer plate mounting bracket 180 along the other side of the microchannel heat exchanger in the thickness direction D3. In yet another embodiment, as shown in FIG. 10, optional partition plates 190 may be mounted on partition plate mounting brackets 180 on both sides in the thickness direction D3 of the microchannel heat exchanger. By selectively installing the optional partition 190 on one side, the other side, or both sides in the thickness direction D3 of the microchannel heat exchanger and adjusting the shape and size of the optional partition 190, a certain degree of wind field adjustment can be achieved, so that both the first coil 110 and the second coil 120 have good heat exchange capacity, and the first coil 110 and the second coil 120 can maintain balanced heat exchange capacity.
The application also provides an air conditioner. The air conditioner may include the microchannel heat exchanger 100 described above.
The air conditioner of the present application has substantially similar advantageous technical effects to the micro-channel heat exchanger 100 described above, and therefore, the detailed description thereof is omitted.
The above description is only a preferred embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present application should be included in the protection scope of the present application.
