Referring to fig. 1-6 in combination, a heat exchanger assembly having heat exchanging gaps comprising at least two gap groups arranged in sequence in a flow direction of a gas; in the flowing direction of the gas, the sizes of the gaps of the gap groups are sequentially reduced; the heat exchanger component is an integrated cabinet heat exchanger component and mainly comprises a compressor, a heat exchanger, an electronic expansion valve, an air return port component, an electrical box 2 component, an upper shell component 31, an air outlet component, a lower shell component 32 and the like. The air conditioner is characterized in that an air return port assembly is arranged at the air return port 1, the air return port assembly comprises an air return port 1, an air return grille and an EC fan, and the air conditioner mainly has the function of enabling air with certain cooling capacity to return to a heat exchanger assembly after heat exchange in a cooled space; the electrical box 2 mainly functions to control the operation of the novel efficient integrated cabinet heat exchanger component; the air outlet 4 component mainly comprises an air outlet 4, an air outlet grid and the like, and is mainly used for releasing cold energy to a cooled space by air.
Because the return air side of integration rack heat exchanger subassembly, the EC fan inhales the air after the heat transfer in return air inlet 1 department, blows to air outlet 4 department downwards, leads to keeping away from more that the return air inlet 1 amount of wind is big more, and the amount of wind that the heat exchanger subassembly is close to one side of return air inlet 1 department is minimum on the contrary. The air quantity is inconsistent, so that the air outlet of the heat exchanger is uneven, and the optimal performance of the heat exchanger cannot be effectively realized. The heat exchange gaps of the heat exchanger assembly are arranged, and each heat exchange gap comprises at least two gap groups which are sequentially arranged in the flowing direction of gas; in the flowing direction of the gas, the gap sizes of the gap groups are reduced in sequence, so that the air passing on the heat exchanger assembly is uniform, and the heat exchange effect is good.

The present application also discloses embodiments in which, when the heat exchanger comprises a finned heat exchanger 8, heat exchange gaps are formed between adjacent two fins 82. The fin heat exchanger 8 comprises a pipeline 81 and fins 82, a heat exchange gap is formed between every two adjacent fins 82, and during heat exchange, gas passes through the fin heat exchanger 8 through the heat exchange gap. This application heat exchanger assembly through adopting different plate distance evaporimeter combination or the microchannel heat exchanger 7 of different plate distances, thereby adjusts the evaporimeter windage and changes the air-out amount of wind, and then makes the evaporimeter air-out more even. Compared with the traditional integrated cabinet heat exchanger component evaporator, the air outlet uniformity of the invention is obviously improved, and the heat exchange effect is improved by about 20%.

The application also discloses some embodiments, and return air inlet 1 sets up in the top of air outlet 4. Because the return air side of integration rack heat exchanger subassembly, the EC fan inhales the air after the heat transfer at unit upper casing 3, blows to the evaporimeter bottom downwards, leads to more downwards the amount of wind more, and the amount of wind on evaporimeter upper portion is minimum on the contrary. The air quantity is inconsistent, so that the air outlet of the evaporator is uneven, and the best performance of the evaporator cannot be effectively realized. Therefore, the flowing direction of the gas is from top to bottom, namely the sizes of the gaps of the gap groups are sequentially reduced from top to bottom, so that the air passing on the heat exchanger assembly is uniform, and the heat exchange effect is good.
