[0045] Please refer to Figures 3 to 10 An embodiment of the present application provides a base device 10 , including a base 11 , a first heat exchange device 12 and a second heat exchange device 13 .

[0046] The base 11 has an air duct for air circulation. Figure 3 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 , Figure 3 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 The arrows in the figure indicate the flow path of the air in the duct.

[0047] See also Figure 4 The base 11 has a first supporting surface 111 and a second supporting surface 112 , and the second supporting surface 112 is spaced apart from the bottom wall 11 a of the base 11 .

[0048] It should be noted that the first supporting surface 111 can be a continuous surface or an abstract surface defined by multiple structures, and the second supporting surface 112 can be a continuous surface or an abstract surface defined by multiple structures.

[0049] The first heat exchange device 12 is disposed in the air duct, and the first support surface 111 is located at the bottom side of the first heat exchange device 12 and is used to support the first heat exchange device 12 . That is, the first heat exchange device 12 is placed on the first support surface 111 .

[0050] In some embodiments, the first heat exchange device 12 has a first bottom surface 12b that contacts the first support surface 111 and is located at substantially the same height. It should be noted that the first bottom surface 12b can be a continuous surface or an abstract surface defined by multiple structures of the first heat exchange device 12.

[0051] The second heat exchange device 13 is disposed in the air duct and is located downstream of the first heat exchange device 12 along the airflow direction. The second support surface 112 is located at the bottom side of the second heat exchange device 13 and is used to support the second heat exchange device 13. That is, the second heat exchange device 13 is placed on the second support surface 112.

[0052] In some embodiments, the second heat exchange device 13 has a second bottom surface 13b that contacts the second support surface 112 and is located at substantially the same height. It should be noted that the second bottom surface 13b can be a continuous surface or an abstract surface defined by multiple structures of the second heat exchange device 13.

[0053] It should be noted that the heat exchange device is used to perform heat exchange on the air flow flowing through the air duct, thereby achieving condensation, dehumidification or heating of the air flow.

[0054] The first supporting surface 111 is located lower than the second supporting surface 112 , that is, the first bottom surface 12 b of the first heat exchange device 12 is located lower than the second bottom surface 13 b of the second heat exchange device 13 .

[0055] In the base device 10 provided in the embodiment of the present application, when air flows through the air duct, it must first pass through the first heat exchange device 12 before flowing to the second heat exchange device 13. Because the first support surface 111 is located lower than the second support surface 112, there is a height difference between the first bottom surface and the second bottom surface, which forces the airflow to pass through the first heat exchange device 12 before passing through the second heat exchange device 13. Although there is a gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 11a of the base, because the first bottom surface 12b is located lower than the second bottom surface 13b, the first bottom surface 12b has a certain shielding effect on the gap, allowing the airflow to flow through the first heat exchange device 12 before the second heat exchange device 13 as much as possible. In other words, when the airflow entering the air duct undergoes heat exchange, it is best to pass through the first heat exchange device 12 before the second heat exchange device 13, allowing the airflow to undergo heat exchange as much as possible, thereby improving the heat exchange processing effect of the airflow.

[0056] In some embodiments, the first heat exchange device 12 may be a heat sink, and the second heat exchange device 13 may be a heat release device. In other embodiments, both the first heat exchange device 12 and the second heat exchange device 13 may serve as heat sinks. In still other embodiments, both the first heat exchange device 12 and the second heat exchange device 13 may serve as heat release devices.

[0057] A heat absorption device absorbs the heat of the air flow and cools the air flow. During the cooling process, the water vapor of the air flow will be condensed into water, thereby realizing the condensation and dehumidification function of the air flow.

[0058] The heat release device heats the air flow.

[0059] In this embodiment, the first heat exchanger 12 and the second heat exchanger 13 are described as heat sinks. In this embodiment, the first and second heat exchangers 12 and 13 are used to condense and dehumidify the airflow. Airflow entering the air duct first passes through the first heat exchanger 12 and then through the second heat exchanger 13. This double condensation and cooling process enhances the condensation and dehumidification performance.

[0060] See also Figure 4 The base device 10 further includes a third heat exchange device 14, which is disposed downstream of the second heat exchange device 13 along the airflow direction, and is used to heat the airflow.

[0061] Please refer to Figure 1The present invention also provides a laundry treatment device, comprising a first drum assembly 20 and a base device 10 according to any embodiment of the present invention. The first drum assembly 20 has a first laundry treatment chamber, and an air duct communicates with the first laundry treatment chamber. The first drum assembly 20 is used to care for laundry.

[0062] The clothing processing device can at least be used to dry clothes. The specific type of the clothing device is not limited here, for example, it can be a dryer or a washer-dryer.

[0063] In some embodiments, the clothing processing device includes a heat pump system, which includes components such as a compressor, an evaporator, and a condenser. The compressor, condenser, and evaporator are connected in series in a refrigerant circuit.

[0064] The working principle of the heat pump system is as follows: the compressor inhales low-pressure gaseous refrigerant, which is compressed by the compressor and discharged as high-pressure gas. The discharged high-pressure gaseous refrigerant enters the condenser, and the refrigerant is cooled by the room temperature air around the condenser and condensed into a high-pressure liquid (at the same time, the heat is transferred to the surrounding air). In other words, the air around the condenser will be heated and heated; 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, it absorbs heat from the surrounding air). In other words, the air around the evaporator will be cooled and cooled, and the refrigerant is sucked into the compressor again and pressurized. This cycle repeats itself continuously to achieve heat exchange.

[0065] In some embodiments, the evaporator can serve as the first heat exchange device 12 and / or the second heat exchange device 13. The condenser can serve as the third heat exchange device 14.

[0066] In this embodiment, the drying principle of the clothing processing equipment is as follows: the hot and humid air flow discharged from the first clothing processing chamber 21 enters the air duct, undergoes the first condensation and dehumidification through the first heat exchange device 12, and then undergoes the second condensation and dehumidification through the second heat exchange device 13. The air flow after condensation and dehumidification is heated by the third heat exchange device 14, and the heated air flow returns to the first clothing processing chamber 21 through the air duct, and the cycle is repeated to achieve continuous drying of the clothes.

[0067] The specific types of the first heat exchange device 12 and the second heat exchange device 13 are not limited. For example, in some embodiments, the first heat exchange device 12 and the second heat exchange device 13 both serve as evaporators of the heat pump system, that is, the heat pump system can be configured with two evaporators. In other embodiments, one of the first heat exchange device 12 and the second heat exchange device 13 is the evaporator of the heat pump system, for example, the first heat exchange device 12 is an evaporator and the second heat exchange device 13 is a liquid cooling device for circulating coolant; or, the second heat exchange device 13 is an evaporator and the first heat exchange device 12 is a liquid cooling device. In still other embodiments, the first heat exchange device 12 and the second heat exchange device 13 can both be liquid cooling devices.

[0068] Specifically, a liquid cooling device for circulating cooling liquid refers to a device that can be used to pass cooling liquid into the liquid cooling device. During the flow of cooling liquid in the liquid cooling device, it is beneficial to keep the outer surface of the liquid cooling device at a relatively low temperature. When the air flow in the air duct flows through the outer surface of the liquid cooling device, the liquid cooling device and the air flow exchange heat. The liquid cooling device absorbs the heat of the air flow and transfers the heat to the coolant in the liquid cooling device. The coolant heats up, while the air flow temperature drops. The water vapor in the air flow reaches a saturated state and condenses into condensed water on the outer surface of the liquid cooling device, thereby achieving the purpose of condensation and dehumidification of the air flow by the liquid cooling device.

[0069] The specific type of the coolant is not limited. 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.

[0070] Exemplarily, the first heat exchange device 12 is a liquid cooling device, the second heat exchange device 13 is an evaporator, and the third heat exchange device 14 is a condenser. In this embodiment, the first heat exchange device 12 performs a first condensation and dehumidification on the airflow entering the air duct, reducing the temperature and humidity of the airflow, and intercepting a portion of impurities such as dander. The airflow after the first condensation and dehumidification flows through the second heat exchange device 13 for a second condensation and dehumidification, further condensing and dehumidifying the airflow. Since the airflow has undergone the first condensation and dehumidification before flowing through the second heat exchange device 13, while ensuring the condensation and dehumidification effect on the airflow, it helps to lower the evaporation temperature of the evaporator, thereby reducing the power consumption of the heat pump system. It is understandable that in other embodiments, the first heat exchange device 12 can be an evaporator or a liquid cooling device for circulating coolant, the second heat exchange device 13 can be a condenser, and the third heat exchange device 14 can be an electric heater.

[0071] The specific type of the coolant is not limited. 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.

[0072] In this embodiment, the drying principle of the laundry processing apparatus is as follows: the hot and humid airflow discharged from the first laundry processing chamber 21 passes through the first heat exchange device 12 for condensation and dehumidification. The condensed and dehumidified airflow passes through the second heat exchange device 13 for a first heating. The first heated airflow passes through the third heat exchange device 13 for a second heating. The heated airflow then returns to the first laundry processing chamber 21 through the air duct, and this cycle repeats, achieving continuous drying of the laundry. The airflow in this embodiment undergoes two heating cycles, resulting in a higher temperature when it returns to the first laundry processing chamber 21, which helps improve the drying effect.

[0073] It is understandable that, in this embodiment, the third heat exchange device 14 may not be provided.

[0074] In other embodiments, the third heat exchange device 14 may also be an electric heating element.

[0075] It should be noted that the low-temperature dry airflow is relative to the moist hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the moist hot airflow. The low temperature in the embodiment of the present application may be room temperature.

[0076] In some embodiments, the clothes treating apparatus includes a housing, a second drum assembly 30 and a frame 40 disposed in the housing.

[0077] The frame 40 is a main supporting structure for fixing and supporting other components of the clothes processing device.

[0078] The base device 10 is mounted on the frame 40 , and the base device 10 and its load transmit the force to the frame 40 .

[0079] For some examples, see Figure 2 The rack 40 includes at least four columns 41, and the four columns 41 extend in the height direction. In the horizontal plane projection, the four columns 41 are distributed at the four vertices of the quadrilateral.

[0080] In the embodiment of the present application, the height direction is Figure 2 and Figure 4 The top-bottom direction in , that is, includes both the direction from top to bottom and the direction from bottom to top.

[0081] For example, the base device 10 can be connected to the four pillars 41 respectively. The base device 10 is located in the area defined by the four pillars 41.

[0082] The base device 10 divides the space in the box into at least a first space and a second space along the height direction. The first barrel assembly 20 is disposed in the first space, and the second barrel assembly 30 is disposed in the second space.

[0083] In some embodiments, the first laundry processing chamber 21 can at least dry the laundry. The second drum assembly 30 has a second laundry processing chamber 31, which can at least wash the laundry.

[0084] In some embodiments, the first space is located above the second space, that is, the first barrel assembly 20 is located higher than the second barrel assembly 30. In other embodiments, the first space may also be located below the second space, that is, the second barrel assembly 30 is located higher than the first barrel assembly 20.

[0085] In some embodiments, the height difference h1 between the first support surface 111 and the second support surface 112 (see Figure 5 ) is 2 mm to 10 mm, i.e., 2 mm ≤ h1 ≤ 10 mm. Within this range, the height difference between the first support surface 111 and the second support surface 112 can maintain the airflow blocking effect of the first heat exchange device 12, allowing the airflow to pass through the first heat exchange device 12 before entering the second heat exchange device 13 as much as possible, while also ensuring that the height of the base device 10 in the laundry processing device is not too high.

[0086] Exemplarily, a height difference h1 between the first supporting surface 111 and the second supporting surface 112 is 5 mm.

[0087] For some examples, see Figure 3 and Figure 4 The base 11 includes a bottom shell 117 and a top cover 118. The top cover 118 is arranged on the top side of the bottom shell 117. The top surface of the first heat exchange device 12 facing the top cover is located at a lower position than the top surface 13a of the second heat exchange device 13. In this way, a first avoidance space is formed between the top surface 12a of the first heat exchange device 12 and the top cover 118. Other components can be installed in the first avoidance space, which helps to make the base device 10 compact.

[0088] It is understood that the top surface 12a of the first heat exchange device 12 refers to the surface of the first heat exchange device 12 where the structure closest to the top cover 118 is located, and can be a continuous surface or an abstract surface defined by multiple structures of the first heat exchange device 12. The top surface 13a of the second heat exchange device 13 refers to the surface of the second heat exchange device 13 where the structure closest to the top cover 118 is located, and can be a continuous surface or an abstract surface defined by multiple structures of the second heat exchange device 13.

[0089] In some embodiments, the height difference h2 between the top surface 13a of the second heat exchange device 13 and the top surface 12a of the first heat exchange device 12 (see Figure 5) is 3 mm to 15 mm, i.e., 3 mm ≤ h2 ≤ 15 mm. This range creates a first clearance space of appropriate size between the top surface 12a of the first heat exchange device and the top cover 118, meeting installation requirements while also preventing a reduction in the height of the first heat exchange device 12 due to a significant height difference (taking the position of the top surface 13a of the second heat exchange device 13 as a reference, a significant height difference would indicate a low height of the first heat exchange device 12, thereby affecting the heat exchange effect between the first heat exchange device 12 and the airflow).

[0090] Exemplarily, a height difference h2 between the top surface 13a of the second heat exchange device 13 and the top surface 12a of the first heat exchange device 12 is 5 mm.

[0091] In some embodiments, the base device 10 includes a functional component, which is disposed between the top surface 12a of the first heat exchange device 12 and the top cover 118. That is, the functional component is disposed in the first avoidance space.

[0092] It should be noted that the functional component refers to a component that can provide functions other than heat exchange.

[0093] For some examples, see Figure 5 At least a portion of the top cover 118 protrudes upward to form a second escape space 118a below the top cover 118, and the functional components are at least partially disposed in the second escape space 118a. In other words, the functional components are disposed in the escape space formed by the first escape space and the second escape space 118a.

[0094] In some embodiments, the height dimension h3 of the second escape space 118a is 1 mm to 4.5 mm, i.e., 1 mm ≤ h3 ≤ 4.5 mm. This range allows the top cover 118 to not protrude significantly upward while still providing the second escape space 118a for accommodating the spray device 17.

[0095] For example, the height dimension h3 of the second avoidance space 118a is 1.5 mm. Figure 4 , functional components include a spray device 17. Please refer to Figure 5 Spraying device 17 has at least one spray port 172. Spraying port 172 is used to spray liquid toward at least one of second heat exchange device 13, first heat exchange device 12, and bottom wall 117a of bottom housing 117. Specifically, spraying device 17 is installed within the clearance space formed between the top surface of first heat exchange device 12 and top cover 118.

[0096] It is understood that, in some embodiments, the spray port 172 can spray liquid toward the second heat exchange device 13 to remove impurities such as dander attached to the surface of the second heat exchange device 13. In some embodiments, the spray port can spray liquid toward the first heat exchange device 12 to remove impurities such as dander attached to the surface of the first heat exchange device 12. In some embodiments, the spray port can spray liquid toward the bottom wall 117a of the bottom shell 117 to clean the bottom wall 117a of the bottom shell 117. In some embodiments, the spray port 172 can spray liquid toward any two of the first heat exchange device 12, the second heat exchange device 13, and the bottom wall 117a of the bottom shell 117. In some embodiments, the spray port can spray liquid toward all of the second heat exchange device 13, the first heat exchange device 12, and the bottom wall 117a of the bottom shell 117.

[0097] It can be understood that the bottom wall 117 a of the bottom shell 117 in this embodiment is the bottom wall 11 a of the base 11 .

[0098] It should be noted that, in the embodiment where the spray port 172 is capable of spraying liquid toward the second heat exchange device 13 , the second heat exchange device 13 is a liquid cooling device or an evaporator for circulating cooling liquid.

[0099] In addition, the liquid sprayed from the spray port 172 can also directly contact the airflow, which helps to cool the airflow, thereby helping to condense and dehumidify the airflow. It should be noted that in this embodiment, the airflow does not need to flow through the spray device 17.

[0100] For some examples, please refer to Figure 7 The spray device 17 extends along a first direction, and includes a plurality of spray ports 172 arranged along the first direction. The spray ports 172 are located above the windward surface 123 of the first heat exchange device 12, and are used to spray liquid onto the windward surface 123. In this embodiment, the liquid sprayed from the spray ports 172 flows from top to bottom, that is, the liquid flows from the top of the windward surface 123 to the bottom of the windward surface 123. At this time, the liquid is not substantially tilted along the direction of airflow when sprayed onto the first heat exchange device 12. Therefore, the liquid does not flush impurities attached to the windward surface 123 into the interior of the first heat exchange device 12, thereby facilitating the removal and removal of impurities.

[0101] It should be noted that the windward surface 123 of the first heat exchange device 12 refers to the surface of the first heat exchange device 12 that first contacts the airflow when the airflow flows through the first heat exchange device 12. The windward surface 123 is not a continuous surface, and the airflow needs to pass through the windward surface 123 head-on.

[0102] For example, Figure 8 and Figure 9As shown, the base 11 includes a protrusion, which protrudes from the upper surface of the bottom wall 11a of the base. The second heat exchange device 13 is supported on the protrusion so that the bottom surface of the second heat exchange device 13 is spaced apart from the bottom wall 11a of the base 11, that is, the second bottom surface 13b is spaced apart from the bottom wall 11a of the base 11.

[0103] In this embodiment, the top surface of the protrusion defines the aforementioned second support surface 112. This arrangement allows liquid generated during heat exchange by the second heat exchange device 13 to drain into the gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 11a of the base 11, facilitating timely drainage of the liquid from the gap and reducing the risk of the lower portion of the second heat exchange device 13 being soaked by the precipitated liquid.

[0104] It should be noted that the specific shape of the protrusion is not limited, as long as a gap is formed between the second bottom surface 13 b of the second heat exchange device 13 and the bottom wall 11 a of the base 11 .

[0105] For example, Figure 8 As shown, the protrusion includes a plurality of ribs 114, and the top surfaces of at least some of the ribs 114 define a second support surface 112. That is, the plurality of ribs 114 jointly support the second heat exchange device 13. In some embodiments, the second heat exchange device 13 extends along a first direction, and the plurality of ribs 114 are spaced apart along the first direction. The spacing between adjacent ribs 114 can guide liquid precipitated from the second heat exchange device 13.

[0106] In some embodiments, the extending direction of the rib 114 intersects with the first direction. In other words, the water flow guiding direction of the rib 114 intersects with the first direction.

[0107] It should be noted that the extending direction of the rib 114 refers to the direction indicated by the straight line connecting the starting point and the end point of the rib 114 .

[0108] For example, Figure 6 As shown, the base device 10 also includes a blocking rib 15, which protrudes from the upper surface of the bottom wall 11a of the base 11 and is arranged on the air outlet side of the second heat exchange device 13. The blocking rib 15 extends along the length direction of the second heat exchange device 13 and is used to block the airflow flowing between the bottom surface of the second heat exchange device 13 and the bottom wall 11a of the base 11.

[0109] In this embodiment, the ribs 15 can block the airflow between the bottom surface of the second heat exchange device 13 and the bottom wall 11a of the base 11, thereby reducing the probability of the airflow directly reaching the third heat exchange device 14 without passing through the heat exchange effect of the second heat exchange device 13, thereby helping to improve the heat exchange effect of the airflow and helping to improve the drying effect.

[0110] In some embodiments, the second heat exchange device 13 extends along a first direction, and the first heat exchange device 12 and the second heat exchange device 13 are arranged along a second direction, wherein the first direction and the second direction intersect, for example, the first direction and the second direction are substantially perpendicular.

[0111] It should be noted that the specific directions of the first direction and the second direction are not limited. For example, the first direction is Figure 3 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 The first direction is the direction shown in Figure 3 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 The direction shown in the second direction.

[0112] For example, Figure 6 As shown, the ribs 15 extend along the first direction.

[0113] Exemplarily, one end of the convex rib 114 is connected to the retaining rib 15 , and the other end extends toward one side in the first direction.

[0114] In some embodiments, the top surface of the blocking rib 15 is located higher than the second support surface 112 , so that the blocking rib 15 can better block the airflow from directly reaching the third heat exchange device 14 without passing through the heat exchange effect of the second heat exchange device 13 .

[0115] In some embodiments, the base 11 includes a first area 115 and a drainage channel 116, the drainage channel 116 is arranged on one side of the first area 115 along the first direction of the base device 10, the drainage channel 116 is provided with a water outlet, the first heat exchange device 12 and the second heat exchange device 13 are arranged along the second direction, wherein the first direction and the second direction intersect.

[0116] The first heat exchange device 12 and the second heat exchange device 13 are at least partially located in the first area 115 , and the bottom wall 116 a of the drainage channel 116 is located lower than the bottom wall 115 a of the first area 115 , so that the liquid in the first area 115 can flow to the drainage channel 116 .

[0117] In this example, liquid generated during the heat exchange process between the first heat exchange device 12 and the second heat exchange device 13 is discharged to the first area 115 . The liquid in the first area 115 can be discharged from the base device 10 through the drainage channel 116 .

[0118] In some embodiments, the first direction is the left-right direction of the clothes processing apparatus. The first heat exchange device 12 and the second heat exchange device 13 are arranged along the front and back of the clothes processing apparatus.

[0119] In some embodiments, such as Figure 5 and Figure 8 As shown, the base assembly 10 further includes a cover plate 16. The cover plate 16 covers the drainage channel 116. Providing the cover plate 16 on the drainage channel 116 minimizes the formation of water vapor in the drainage channel 116 under the negative pressure of the airflow and prevents the water vapor from entering the downstream of the air duct, thereby minimizing the entry of the water vapor into the first laundry processing chamber 21.

[0120] like Figure 5 As shown, one end of the first heat exchange device 12 along the first direction of the base device 10 is supported on the bottom wall 115 a of the first area 115 , and the other end of the first heat exchange device 12 along the first direction of the base device 10 is supported on the cover plate 16 .

[0121] In this embodiment, the portion of the cover plate 16 that contacts the first heat exchange device 12 constitutes a portion of the first support surface 111. Thus, the cover plate 16 also supports the first heat exchange device 12, thereby improving the installation stability of the first heat exchange device 12. Furthermore, the cover plate 16 fully utilizes the space above the drainage channel 116, thereby reducing the space occupied by the first heat exchange device 12 in the first direction relative to the first area 115, thereby contributing to a compact structure of the base device 10.

[0122] For some examples, see Figure 6 The first heat exchange device 12 has a drain port 1212, and the cover plate 16 has a liquid outlet 161. Alternatively, the area of the drainage channel 116 not covered by the cover plate 16 forms the liquid outlet 161. The drain port 1212 is located above the cover plate 16, allowing the coolant discharged from the drain port 1212 to flow through the liquid outlet 161 into the drainage channel 116. This allows the coolant in the first heat exchange device 12 to be discharged directly into the drainage channel 116 through the liquid outlet 161 without passing through the first area 115, thereby improving the drainage efficiency of the base assembly 10.

[0123] It should be noted that the cover plate 16 has a liquid outlet 161, and the shape of the liquid outlet 161 is independently defined by the cover plate 16. The area not covered by the cover plate 16 refers to the area where the liquid outlet 161 is located outside the overall outline of the cover plate 16. For example, if the drain channel 116 is 100 cm long and the cover plate 16 is 80 cm long, and there is a 20 cm gap between the end of the cover plate 16 and the end of the drain channel 116, then this gap constitutes the aforementioned liquid outlet 161.

[0124] In some embodiments, in the horizontal plane projection, the drain port 1212 is located within the projection range of the liquid outlet 161. In this way, along the height direction of the clothing processing equipment, the coolant discharged from the drain port 1212 can directly flow through the liquid outlet 161 under the action of gravity into the drainage channel 116, which helps to improve the drainage efficiency and no longer needs to arrange a drainage pipe from the drain port 1212 to the liquid outlet 161, which helps to save layout space and layout costs.

[0125] For example, see Figure 8 、 Figure 9 and Figure 10 The bottom wall 115a of the first region 115 includes a first portion 1151, a flat portion 1152, and a second portion 1153. The second heat exchange device 13 is located above the first portion 1151, and one end of the first heat exchange device 12 is supported by the flat portion 1152. In this embodiment, the flat portion 1152 constitutes a portion of the first support surface 111.

[0126] The second portion 1153 extends downwardly from the flat portion 1152 toward the drainage channel 116 . The second portion 1153 is lower than the first portion 1151 and the flat portion 1152 , so that the liquid in the first area 115 is guided to the drainage channel 116 through the second portion 1153 .

[0127] In this embodiment, the second portion 1153 primarily serves as a drainage and diversion mechanism. Liquid generated during the heat exchange process between the second heat exchange device 13 and the airflow is discharged through the first portion 1151 to the second portion 1153, and then directed to the drainage channel 116 through the second portion 1153. Liquid generated during the heat exchange process between the first heat exchange device 12 and the airflow is directly directed to the drainage channel 116 through the second portion 1153. Because the second portion 1153 is positioned lower than the first portion 1151, this helps reduce the probability of liquid in the second portion 1153, carried by the airflow, flowing along the upper surface of the bottom wall 115a of the first region 115 toward the downstream side of the air duct.

[0128] In some embodiments, multiple ribs 114 are provided on the first portion 1151 , and the multiple ribs 114 are arranged at intervals along the first direction, the extension direction of the ribs 114 intersects with the first direction, and the intervals between the multiple ribs 114 form a diversion channel for the liquid in the first portion 1151 .

[0129] In some embodiments, one end of the rib 114 is connected to the retaining rib 15, and the other end extends toward the first direction and close to the side where the drainage channel 16 is located, so that water in the first part 1151 can be quickly discharged to the second part 1153 along the diversion channel.

[0130] In some embodiments, the first bottom surface 12b of the first heat exchange device 12 is located higher than the junction of the first part 1151 and the second part 1153. On the one hand, the probability of the first heat exchange device 12 blocking the liquid flowing from the first part 1151 to the second part 1153 is reduced. On the other hand, the probability of the liquid flowing from the first part 1151 to the second part 1153 flushing the first heat exchange device 12 is also reduced.

[0131] For example, Figures 8 to 10 As shown, a step structure 1154 is formed at the junction of the second part 1153 and the first part 1151, so that the liquid in the second part 1153 cannot flow back to the first part 1151 with the airflow. The step structure 1154 can better block the liquid in the second part 1153, improve the drainage effect of the base device 10, and further reduce the probability of the liquid in the second part 1153 flowing along the upper surface of the bottom wall 115a of the first area 115 toward the downstream of the air duct under the carrying effect of the airflow.

[0132] In some embodiments, the first heat exchange device 12 includes a fin assembly 122 and a cooling pipe 121 for circulating cooling liquid, and the first support surface 111 contacts the bottom surface of the fin assembly 122. In other words, the first bottom surface 12b of the first heat exchange device 12 is the bottom surface of the fin assembly 122.

[0133] In some embodiments, the liquid cooling pipe 121 includes a liquid inlet 1211 and a liquid outlet 1212. The liquid inlet 1211 and the liquid outlet 1212 are disposed on one side of the fin assembly 122 along the first direction of the base assembly 10 and close to the drainage channel 116. The liquid inlet 1211 and the liquid outlet 1212 are disposed on the same side of the fin assembly 122 to facilitate piping.

[0134] Liquid inlet 1211 needs to be connected to the water supply component, and the area above drain channel 116 can provide sufficient space for liquid inlet 1211 and the water supply component. Drain port 1212 is located on the side near drain channel 116 to facilitate the discharge of coolant from liquid cooling line 121. This allows the coolant in liquid cooling line 121 to be discharged directly into drain channel 116 without passing through first area 115, allowing the coolant to be discharged in a timely manner.

[0135] In some embodiments, the position of the liquid inlet 1211 is higher than the position of the liquid outlet 1212. The height difference between the liquid inlet 1211 and the liquid outlet 1212 is used to allow the liquid cooling to flow under the action of its own gravity, thereby reducing the pressure requirement of the cooling liquid flowing into the liquid inlet 1211.
