[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] According to an embodiment of the present utility model, a heat exchange structure is provided. Figures 1 to 6 , including: a heat exchange component 1, used for exchanging heat; a water receiving tray 2, the water receiving tray 2 has a water receiving groove 21 and a drain port 22 connected to the water receiving groove 21; the water receiving groove 21 is used to accommodate the fluid flowing down from the heat exchange component 1; a first support part 3, located in the water receiving groove 21, and a water receiving part 31 is provided on the first support part 3; a second support part 4, located in the water receiving groove 21, and the heat exchange component 1 is connected to the second support part 4; wherein, a water receiving channel 23 connected to the water receiving groove 21 is provided between the first support part 3 and the second support part 4, and the water receiving part 31 can be movably arranged to open or block the water receiving channel 23.

[0029] With the above arrangement, a water receiving pan 2 is provided below the heat exchange component 1, and a water receiving portion 31 is provided on the water receiving pan 2. The water receiving portion 31 can move according to the state of the heat exchange component 1. When the heat exchange component 1 needs to receive water, the water receiving portion 31 moves to a state where the water receiving channel 23 is open. At this time, the condensed water on the heat exchange component 1 mixed with dust attached to the heat exchange component 1 flows into the water receiving groove 21 through the water receiving channel 23; when the condensed water on the heat exchange component 1 is not enough to flow down, the water receiving portion 31 moves to a state where the water receiving channel 23 is closed, so as to improve the sealing of the system, thereby solving the technical problem that the heat exchange structure of the air conditioner in the related art is prone to collect condensed water and dust.

[0030] In the heat exchange structure of this embodiment, see Figure 2 The heat exchange component 1 is provided with a temperature and humidity sensor 5, which is connected to the water receiving part 31 by signal to drive the water receiving part 31 to move. In this way, the temperature and humidity sensor 5 can detect the temperature and humidity of the heat exchange component 1 in real time, and control the movement of the water receiving part 31 according to the detected temperature and humidity of the heat exchange component 1 to open or block the water receiving channel 23, so that the water receiving channel 23 is kept in a closed state when water is no longer needed, so as to improve the sealing performance of the system.

[0031] Preferably, a motor is provided at one end of the water receiving part 31, the water receiving part 31 is connected to the motor output shaft, the motor is connected to the temperature and humidity sensor 5 signal, and the movement of the water receiving part 31 is controlled by the rotation of the motor output shaft.

[0032] In the heat exchange structure of this embodiment, see Figure 1 , a third support portion 6 is provided in the water receiving tray 2, and the heat exchange assembly 1 includes a first heat exchange component 11 provided on the second support portion 4 and a second heat exchange component 12 provided on the third support portion 6. In this way, three support portions are designed in the water receiving tray 2, which are used to support the first heat exchange component 11, the second heat exchange component 12 and the water receiving portion 31 respectively. The first heat exchange component 11 and the second heat exchange component 12 are both fixed in the water receiving tray 2, and the condensed water on the first heat exchange component 11 and the second heat exchange component 12 can flow into the water receiving groove 21 through the water receiving channel 23, so as to solve the technical problem that the heat exchange structure of the air conditioner in the related art is easy to collect condensed water and dust.

[0033] Preferably, the first heat exchange component 11 is a radiation plate, and the second heat exchange component 12 is a surface cooler.

[0034] In the heat exchange structure of this embodiment, see Figure 1 , Figure 3The water receiving tray 2 includes a bottom plate 24 and a bottom shell 25, the bottom plate 24 is connected to the bottom shell 25, and the bottom shell 25 forms a water receiving groove 21, and the water receiving groove 21 includes: a first water receiving groove 211, located between the first support part 3 and the second support part 4; a second water receiving groove 212, located between the second support part 4 and the third support part 6; a third water receiving groove 213, located between the third support part 6 and the bottom shell 25 of the water receiving tray 2. In this way, the water receiving tray 2 is set at the bottom of the unit, and the condensed water on the first heat exchange component 11 and the second heat exchange component 12 mixed with dust flows into the three water receiving grooves 21 in the water receiving tray 2.

[0035] In the heat exchange structure of this embodiment, see Figure 1 , Figure 3 The bottom plate 24 includes: a mounting plate 241, on which the first support portion 3, the second support portion 4 and the third support portion 6 are all arranged; a drain plate 242, which is connected to the mounting plate 241, and on which the drain port 22 is arranged. In this way, the condensed water flowing down from the first heat exchange component 11 and the second heat exchange component 12 flows through the mounting plate 241 and the drain plate 242 in sequence, and then is discharged from the water receiving tank 21 through the drain port 22 on the drain plate 242.

[0036] In the heat exchange structure of this embodiment, see Figure 3 , there are two drain plates 242, and the two drain plates 242 are respectively connected to the opposite ends of the mounting plate 241; and / or, the drain plates 242 are provided with dust collecting grooves 2421, which are recessed in the plate surface of the drain plates 242, penetrate the water receiving groove 21, and extend to the bottom shell 25. In this way, when the dust or other debris carried by the condensed water flowing down from the first heat exchange component 11 and the second heat exchange component 12 flows to the drain ports 22 at both ends of the mounting plate 241 with the water flow, the dust or debris in the condensed water will settle in the dust collecting grooves 2421 to prevent the drain ports 22 from being blocked.

[0037] In the heat exchange structure of this embodiment, see Figure 4 , Figure 5 The heat exchange structure also includes: a shell 7, which is connected to the water tray 2, and the shell 7 encloses a heat exchange cavity, and the heat exchange component 1 is located in the heat exchange cavity; the shell 7 is provided with an air inlet 71 and an air outlet 72 connected to the heat exchange cavity; and a fan component 8, which is relatively rotatably connected to the drain plate 242 to drive the air flow into the air inlet 71. In this way, the fan component 8 is arranged in the heat exchange cavity, which can speed up the flow rate of the air flow from the air inlet 71 to the air outlet 72, increase the air flow passing through the heat exchange cavity within a fixed time, and improve the heat exchange effect of the heat exchange component 1.

[0038] In the heat exchange structure of this embodiment, see Figure 6The heat exchange assembly includes: a fixed plate 15, the fixed plate 15 is connected to the second support part 4, and a water retaining protrusion 151 is provided on the fixed plate 15; the water receiving part 31 is relatively rotatably connected to the first support part 3, so that the water receiving part 31 abuts against the water retaining protrusion 151, thereby blocking the water receiving channel 23, or the water receiving part 31 is separated from the water retaining protrusion 151, thereby opening the water receiving channel 23. In this way, the water retaining protrusion 151 provided on the fixed plate 15 plays a role in limiting the movement of the water receiving part 31. When the water receiving part 31 rotates to abut against the water retaining protrusion 151, the water receiving part 31 stops rotating and cooperates with the water retaining protrusion 151 to block the water receiving channel 23.

[0039] In the heat exchange structure of this embodiment, see Figure 6 , a heat exchange coil 13 is arranged on the fixed plate 15; the heat exchange assembly 1 also includes a baffle 14, which is arranged at an interval with the fixed plate 15, and the heat exchange coil 13 is located between the fixed plate 15 and the baffle 14. In this way, the heat exchange coil 13 is surrounded by the baffle 14 and the fixed plate 15, which not only fixes the heat exchange coil 13, but also protects the heat exchange coil 13 and isolates dust and debris, so that dust and debris in the air fall on the baffle 14 and the fixed plate 15, and flow down with the condensed water, thereby preventing dust and debris from accumulating on the heat exchange coil 13 and affecting the heat exchange effect.

[0040] This embodiment provides an air conditioner, including the above-mentioned heat exchange structure.

[0041] Specifically, see Figures 1 to 6 In the heat exchange structure, the water receiving pan 2 is at the bottom of the air conditioner unit, and the heat exchange component 1 is fixed on the bottom plate 24. The condensed water flowing down from the first heat exchange component 11 and the second heat exchange component 12 flows into the water receiving pan 2. Three support parts are designed on the water receiving pan 2 to support the first heat exchange component 11, the second heat exchange component 12 and the water receiving part 31. Dust collecting grooves 2421 are designed near the two drain ports 22 of the water receiving pan 2. When dust or other debris on the condensed water flows to the two drain ports 22 with the water, the dust or debris in the condensed water will settle in the dust collecting grooves 2421 to prevent the drain ports 22 from being blocked. The water receiving part 31 and the motor are designed on the water receiving pan 2, and the temperature and humidity sensor 5 is designed on the heat exchange component 1 to collect the ambient temperature and humidity. In cooling mode, when the heat exchange component 1 is working, the real-time dew point temperature is obtained by calculating the ambient temperature and humidity collected by the temperature and humidity sensor 5 and the outlet pipe temperature of the heat exchange coil 13, and the movement of the motor and the water receiving part 31 is controlled so that the condensed water on the heat exchange component 1 can be retained in the water receiving tray 2, thereby solving the technical problem in the related art that the heat exchange structure of the air conditioner is prone to accumulate condensed water and dust.

[0042] The present embodiment provides a control method applicable to the above-mentioned heat exchange structure, and the control method includes: calculating the dew point temperature according to the ambient temperature and ambient humidity of the heat exchange component 1, and the pipe temperature of the heat exchange component 1; when the dew point temperature is greater than the ambient temperature + △T, controlling the water receiving part 31 to block the water receiving channel 23 of the heat exchange structure; when the dew point temperature is less than or equal to the ambient temperature + △T, controlling the water receiving part 31 to open the water receiving channel 23 of the heat exchange structure.

[0043] Specifically, in the cooling mode, when the heat exchange component 1 is working, the real-time dew point temperature is obtained by calculating the ambient temperature and humidity collected by the temperature and humidity sensor 5 and the outlet pipe temperature of the heat exchange coil 13. When the dew point temperature is greater than the ambient temperature + △T, the water receiving plate is in a stationary state; when the dew point temperature is not greater than the ambient temperature + △T, the motor starts, and the water receiving part 31 runs to the open position to guide the condensed water on the heat exchange component 1 into the water receiving tray 2.

[0044] Preferably, △T is 2°C. Since the temperature collection accuracy of the resistive temperature sensing package is 0.5°C, there is a deviation between the ambient temperature and the temperature collected by the air outlet temperature sensing package. In order to prevent condensation of the heat exchange component 1, considering the reliability of the system operation, a temperature increase of +2°C can effectively prevent condensed water from dripping.
