[0033] Please refer to Figure 1-Figure 3 The embodiment of the present application provides a heat exchange component, including a heat absorption device 1. The heat absorption device 1 includes a first pipeline 11, a second pipeline 12 and a fin assembly 13.

[0034] The first pipeline 11 and the second pipeline 12 are not connected to each other. The first pipeline 11 is used to circulate the refrigerant, and the second pipeline 12 is used to circulate the cooling liquid. In other words, the refrigerant in the first pipeline 11 and the cooling liquid in the second pipeline 12 will not be exchanged.

[0035] In some embodiments, the coolant is water, which can be tap water, salt water, etc. In other embodiments, the coolant can also be other liquids. Refrigerant, also known as refrigerant, is a medium substance used by the heat pump system to complete the heat exchange cycle.

[0036] The first pipeline 11 and the second pipeline 12 are both provided in the fin assembly 13, that is, the first pipeline 11 and the second pipeline 12 share the fin assembly 13. In other words, the combination of the first pipeline 11 for circulating the refrigerant and the corresponding part of the fin assembly 13 is equivalent to the evaporator, and the second pipeline 12 for circulating the coolant and the corresponding fin assembly 13 is equivalent to the water cooling device.

[0037] In the heat exchange assembly provided in the embodiment of the present application, when the airflow flows through the heat absorbing device 1, the first pipeline 11 and the second pipeline 12 can both play a role in condensing and dehumidifying the airflow, that is, the condensing and dehumidifying effect of the heat exchange assembly on the airflow can be enhanced. In addition, the first pipeline 11 and the second pipeline 12 share the fin assembly 13, which can be understood as integrating the water cooling device and the evaporator in the related technology, which helps to reduce the manufacturing cost, and at the same time makes the structure compact and saves the layout space.

[0038] It should be noted that the specific type of the clothing processing device is not limited here, for example, it can be a clothes dryer or a washer-dryer.

[0039] An embodiment of the present application provides a clothing processing device, including a drum assembly, a drying channel shell 3 and a heat exchange assembly provided in the embodiment of the present application, the drum assembly has a clothing processing chamber, the drying channel shell 3 has an air duct connected to the clothing processing chamber, and the heat exchange assembly is arranged in the air duct.

[0040] It should be noted that the clothing processing equipment includes a heat pump system, and the heat pump system includes components such as a compressor, a condenser, and an evaporator. The compressor, the condenser, and the evaporator are connected in series in a refrigerant circuit.

[0041] The working principle of the clothing processing equipment is as follows: the hot and humid airflow discharged from the clothing processing chamber enters the air duct, is condensed and cooled by the heat absorption device 1, the cooled airflow is heated by the condenser, and the heated airflow returns to the clothing processing chamber through the air duct, and this cycle is repeated to achieve continuous drying of the clothes.

[0042] The working principle of the heat pump system is as follows: the compressor inhales low-pressure gaseous refrigerant, which is discharged as high-pressure gas after being compressed by the compressor. The discharged high-pressure gaseous refrigerant enters the condenser, is cooled by the room temperature air around the condenser, and condenses into a high-pressure liquid (at the same time, transfers heat to the surrounding air). In other words, the air around the condenser will be heated and heated up; the high-pressure liquid refrigerant flows through the throttling device to throttle and reduce the pressure, and becomes a low-pressure and low-temperature gas-liquid two-phase mixture. The gas-liquid two-phase mixture enters the evaporator, and the liquid refrigerant therein evaporates and cools in the evaporator (at the same time, absorbs heat from the surrounding air). In other words, the air around the evaporator will be cooled and lowered in temperature, and then be sucked in by the compressor again for pressurization. This cycle repeats itself continuously to achieve heat exchange.

[0043] It should be noted that the low-temperature dry airflow is relative to the humid hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid hot airflow. The low temperature in the embodiment of the present application may be room temperature.

[0044] In some embodiments, the second pipeline 12 is arranged upstream of the first pipeline 11 along the air flow direction. That is, when the airflow enters the air duct of the drying duct shell 3, the airflow first flows through the area where the second pipeline 12 is located, and undergoes the first cooling, that is, undergoes the first condensation and dehumidification. The cooled airflow continues to flow to the area where the first pipeline 11 is located, and undergoes the second cooling, that is, undergoes the second condensation and dehumidification, thereby improving the condensation and dehumidification effect on the airflow, and is also conducive to reducing the workload of the compressor, thereby reducing the energy consumption of the compressor.

[0045] It is understandable that in some other embodiments, the second pipeline 12 may also be arranged alternately with the first pipeline 11, and it is only necessary to ensure that the first pipeline 11 and the second pipeline 12 are not connected to each other.

[0046] For example, Figure 1 and Figure 2As shown, the first pipeline 11 includes a plurality of first straight pipe sections 111 and a plurality of first curved pipe sections 112. Two adjacent first straight pipe sections 111 are connected by the first curved pipe section 112, so that the first pipeline 11 forms a winding structure, which is convenient for increasing the length of the first pipeline 11 in a limited space. The plurality of first straight pipe sections 111 penetrate the opposite ends of the fin assembly 13 along the first direction. At least one first curved pipe section 112 is respectively provided at the opposite ends of the fin assembly 13 along the first direction. In other words, the first pipeline 11 is only arranged with the first straight pipe section 111 inside the fin assembly 13, thereby reducing the occupied space of the first pipeline 11 on the fin assembly 13 as much as possible, thereby helping to reduce the occupied space of the heat absorption device 1.

[0047] The second pipeline 12 includes a plurality of second straight pipe sections 121 and a plurality of second curved pipe sections 122. Two adjacent second straight pipe sections 121 are connected by the second curved pipe section 122, so as to increase the length of the second pipeline 12 in a limited space. The plurality of second straight pipe sections 121 pass through the opposite ends of the fin assembly 13 along the first direction.

[0048] The two opposite ends of the fin assembly 13 along the first direction are respectively provided with at least one first curved pipe segment 112 and at least one second curved pipe segment 122. Specifically, the two opposite ends of the fin assembly 13 along the first direction are respectively the first end and the second end, and the first end of the fin assembly 13 is provided with at least one first curved pipe segment 112 and at least one second curved pipe segment 122, and the second end of the fin assembly 13 is also provided with at least one first curved pipe segment 112 and at least one second curved pipe segment 122.

[0049] That is, the second pipeline 12 is only provided with the second straight pipe section 121 inside the fin assembly 13 , thereby minimizing the space occupied by the second pipeline 12 on the fin assembly 13 , thereby helping to reduce the space occupied by the heat absorption device 1 .

[0050] When the internal space of the drying tunnel shell 3 is limited, the first pipeline 11 and the second pipeline 12 share the fin assembly 13 and only the first straight pipe section 111 and the second straight pipe section 121 are arranged on the fin assembly 13, which increases the condensation and dehumidification effect while reducing the overall occupied space of the heat absorption device 1 as much as possible.

[0051] It should be noted that the plurality of first straight pipe sections may be parallel to each other or may not be parallel to each other. The first straight pipe sections may be arranged horizontally or may be arranged inclined relative to the horizontal plane.

[0052] The plurality of second straight pipe sections may be parallel to each other or may not be parallel to each other. The second straight pipe sections may be arranged horizontally or may be arranged inclined relative to the horizontal plane.

[0053] The first straight pipe section and the second straight pipe section may be parallel or non-parallel.

[0054] It should be noted that the specific direction of the first direction is not limited. Figure 1 , Figure 3 and Figure 5 The direction shown in the first direction.

[0055] In some embodiments, the plurality of first straight pipe segments 111 and the plurality of second straight pipe segments 121 are at least partially staggered in the height direction of the heat exchange component, which is beneficial for dividing a single airflow into multiple airflows, thereby improving the condensation and dehumidification effect.

[0056] For some examples, see Figure 2 The multiple first straight pipe sections and the multiple second straight pipe sections are collectively divided into multiple pipe groups 14, each pipe group 14 includes multiple first straight pipe sections and / or second straight pipe sections arranged at intervals along the height direction of the heat exchange component, and two adjacent pipe groups 14 are staggered along the height direction. Figure 2 In the figure, the dotted line frame shows a tube group 14. For example, Figure 2 Five tube groups 14 are shown. This helps to increase the heat exchange area between the airflow and the fin assembly 13, and improves the condensation and dehumidification effect.

[0057] It should be noted that, along the height direction, the straight pipe sections between the multiple pipe groups 14 can be aligned or staggered.

[0058] It should be noted that the pipe group 14 groups all the first straight pipe sections 111 and the second straight pipe sections 121 . The same pipe group 14 may be all first straight pipe sections 111 , all second straight pipe sections 121 , or part first straight pipe sections 111 and the other part second straight pipe sections 121 .

[0059] For some specific embodiments, please refer to Figure 2 , Figure 2 The first dotted line frame on the left side of the paper shows one of the tube groups 14, which is composed entirely of first straight tube sections 111. The remaining tube groups 14 are composed entirely of second straight tube sections 121.

[0060] The height direction of the heat exchange component is Figure 1 , Figure 2 , Figure 3 and Figure 4 Direction shown in the middle height direction.

[0061] For example, Figure 3 As shown, the second pipeline 12 has a liquid inlet 123 and a liquid outlet 124, and the liquid inlet 123 and the liquid outlet 124 are arranged on the same side of the heat absorption device 1. In this way, the pipe layout can be convenient.

[0062] In some embodiments, the position of the liquid inlet 123 is higher than that of the liquid outlet 124 , and the height difference between the liquid inlet 123 and the liquid outlet 124 is used to allow the water to flow under its own gravity, thereby reducing the water pressure requirement of the water flow at the water inlet 123 .

[0063] In some embodiments, the heat exchange assembly further includes a heat release device 2, which is disposed on the air outlet side of the heat absorption device 1 and can heat the airflow. In some embodiments, the heat release device 2 is a condenser of a heat pump system.

[0064] For example, Figure 4 and Figure 5 As shown, the drying tunnel shell 3 has a first area 31 and a second area 32, the heat absorption device 1 is arranged in the first area 31, the second area 32 is located at the first side of the first area 31 along the first direction, and the side wall or the bottom wall of the second area 32 is provided with a water outlet 33, and the water outlet 33 is used to discharge the liquid in the second area 32. That is, the condensed water precipitated by the heat absorption device 1 during the condensation and dehumidification process will be discharged to the second area 32 through the first area 31, and finally discharged to the outside of the drying tunnel shell 3 through the water outlet 33.

[0065] For example, Figure 3 As shown, the liquid inlet 123 and the liquid drain 124 of the second pipeline 12 are arranged on the first side of the heat absorption device 1 along the first direction, that is, the liquid inlet 123 and the liquid drain 124 are arranged close to the second area 32. In this way, the liquid drain 124 can discharge the coolant of the second pipeline 12 directly to the bottom wall of the second area 32 without passing through the first area 31. The first area 31 needs to store the heat absorption device 1, and the space for holding the coolant is limited. The liquid drain 124 discharges the coolant to the bottom wall of the second area 32, which helps to reduce the degree of liquid accumulation in the first area 31. In addition, the water outlet 33 is arranged on the side wall or bottom wall of the second area 32, so that the coolant discharged from the liquid drain 124 can be more conveniently discharged from the heat exchange component, which helps to reduce the degree of liquid accumulation in the drying channel shell 3. In addition, the liquid inlet 123 needs to be connected to the water supply component, and the second area 32 can provide sufficient space for the liquid inlet 123 to be connected to the water supply component.

[0066] In some embodiments, the bottom wall of the second area 32 is tilted downward toward the water outlet 33. At this time, the liquid in the second area 32 can be quickly discharged to the water outlet 33 along the downward tilted bottom wall, which helps to improve the drainage efficiency and thus reduce the degree of liquid accumulation in the drying channel shell 3.

[0067] In some embodiments, the barrel assembly includes an outer barrel and an inner barrel arranged in the outer barrel, the clothing processing chamber is arranged in the inner barrel, the outer barrel is provided with a water inlet, and the water outlet 33 of the second area 32 is connected with the water inlet of the outer barrel, that is, the liquid in the second area 32 can flow into the water inlet through the water outlet 33 and then enter the outer barrel, and finally be discharged through the outer barrel.

[0068] In some embodiments, the clothing processing device further includes an auxiliary heating component 4 disposed in the air duct, the auxiliary heating component 4 is disposed downstream of the heat exchange component along the air flow direction, and the auxiliary heating component 4 is used to heat the airflow passing through the auxiliary heating component 4. The auxiliary heating component 4 is used to further heat the airflow obtained by passing through the heat exchange component, which helps to further increase the temperature of the airflow, thereby improving the drying efficiency.
