[0046] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0048] Combination Figures 1-10 As shown, this embodiment of the disclosure provides a fresh air blower 100, including a housing 10 and an outer pipe 30, and also includes a fan and / or a heat exchange core 40.

[0049] The housing 10 defines the installation space and is provided with a first air inlet / outlet 112 and a second air inlet / outlet 113. An outer tube 30 is sleeved on the outside of the housing 10. The wall is provided with a through hole, and the outer tube 30 passes through the through hole. One of the first air inlet / outlet 112 and the second air inlet / outlet 113 is located indoors and connected to the interior, while the other of the first air inlet / outlet 112 and the second air inlet / outlet 113 is located outdoors and connected to the exterior.

[0050] like Figure 2 ,Figure 4 and Figure 5 As shown, the housing 10 includes a first housing segment 101 and a second housing segment 106. The first housing segment 101 defines a first mounting space 108, and the second housing segment 106 defines a second mounting space 109.

[0051] The heat exchanger 40 and / or the fan are located within the first installation space 108 and / or the second installation space 109. The heat exchanger 40 is located within the first installation space 108 and / or the second installation space 109; the fan is located within the first installation space 108 and / or the second installation space 109.

[0052] Both the first air inlet / outlet 112 and the second air inlet / outlet 113 are connected to the installation space. Under the action of the fan, air enters the installation space through one of the first air inlet / outlet 112 and the second air inlet / outlet 113 and exchanges heat with the heat exchange core 40, and then flows out from the other of the first air inlet / outlet 112 and the second air inlet / outlet 113.

[0053] The fresh air unit 100 also includes a panel 50, which is located indoors and has a third air inlet / outlet 501. One of the first air inlet / outlet 112 and the second air inlet / outlet 113 that is connected to the indoors is connected to the indoors through the third air inlet / outlet 501.

[0054] Optionally, such as Figure 2 As shown, the heat exchange core 40 is disposed in one of the first mounting space 108 and the second mounting space 109, and the fan is disposed in the other of the first mounting space 108 and the second mounting space 109. In other words, one of the heat exchange core 40 and the fan is disposed in the first mounting space 108, and the other of the heat exchange core 40 and the fan is disposed in the second mounting space 109. The first shell section 101 and the second shell section 106 are detachably connected.

[0055] like Figure 4 and Figure 5 As shown, the first shell section 101 and the second shell section 106 are detachably connected, thus separating the first shell section 101 and the second shell section 106. The heat exchange core 40 is located in one of the first shell section 101 and the second shell section 106, and the fan is located in the other of the first shell section 101 and the second shell section 106. This separation of the heat exchange core 40 and the fan facilitates maintenance, replacement, or cleaning of the heat exchange core 40 and the fan. Furthermore, it allows for a modular design of the first shell section 101 and the second shell section 106, reducing the cost of the fresh air unit 100.

[0056] Optionally, the first shell section 101 is provided with a snap-fit ​​part, and the second shell section 106 is provided with a snap-fit ​​mating part.

[0057] The snap-fit ​​part and the snap-fit ​​mating part snap together so that the first shell section 101 and the second shell section 106 snap together.

[0058] The design of the snap-fit ​​part and the snap-fit ​​mating part enables quick disassembly and installation of the first shell section 101 and the second shell section 106. This snap-fit ​​structure simplifies the assembly process, improves the assembly efficiency of the equipment, and ensures the stability of the connection.

[0059] It is understandable that the first shell section 101 and the second shell section 106 can also be connected by other detachable means such as screw connection or magnetic connection.

[0060] Optionally, such as Figure 10 As shown, the snap-fit ​​part and / or snap-fit ​​mating part are provided with a guide slope 1041 to guide the snap-fit ​​part to insert into or disengage from the snap-fit ​​mating part.

[0061] A guide ramp 1041 is provided on the snap-fit ​​part and / or snap-fit ​​mating part to make the insertion and disengagement between the snap-fit ​​part and the snap-fit ​​mating part smoother. This design reduces friction and resistance during assembly of the snap-fit ​​part and the snap-fit ​​mating part, improves the user's operating experience, and reduces wear on the snap-fit ​​part and the snap-fit ​​mating part during assembly.

[0062] Optionally, such as Figure 5 As shown, the snap-fit ​​part includes a snap fastener 104, and the snap-fit ​​mating part includes a snap groove 103. The snap fastener 104 is disposed on the outer wall surface of the first shell section 101. Alternatively, the snap-fit ​​part includes a snap groove 103, and the snap-fit ​​mating part includes a snap fastener 104. The snap fastener 104 is disposed on the outer wall surface of the second shell section 106.

[0063] Along the direction in which the buckle 104 is inserted into the slot 103, the buckle 104 is tilted inward to form a guide slope 1041, wherein the direction closer to the axis of the installation space is inward, and the direction farther from the axis of the installation space is outward.

[0064] When the buckle 104 is inserted into the slot 103, the guide slope 1041 gradually inserts into the slot 103, so that the buckle 104 can be smoothly inserted into the slot 103. This design further optimizes the convenience and stability of the snap-fit, ensuring that the connection between the first shell section 101 and the second shell section 106 is both fast and firm, and improving the overall reliability of the equipment.

[0065] Optionally, such as Figure 4 As shown, the first shell section 101 and the second shell section 106 are arranged sequentially along the length of the installation space.

[0066] Thus, one of the heat exchange core 40 and the fan can be located within one of the first shell section 101 and the second shell section 106, and the other of the heat exchange core 40 and the fan can be located within the other of the first shell section 101 and the second shell section 106. When the first shell section 101 and the second shell section 106 are connected, the heat exchange core 40 and the fan work together to realize the air intake and exhaust functions of the fresh air fan 100; when the first shell section 101 and the second shell section 106 are separated, the heat exchange core 40 and the fan are separated, which facilitates the maintenance, replacement or cleaning of the heat exchange core 40 and the fan.

[0067] Optionally, the first shell section 101 and the second shell section 106 are arranged sequentially along the circumference of the installation space.

[0068] The circumferential portion of the heat exchange core 40 is located within the first shell section 101, and the other circumferential portion is located within the second shell section 106. Similarly, the circumferential portion of the fan is located within the first shell section 101, and the other circumferential portion is located within the second shell section 106. When the first shell section 101 and the second shell section 106 are connected, the heat exchange core 40 and the fan work together to achieve the air intake and exhaust functions of the fresh air unit 100. When the first shell section 101 and the second shell section 106 are separated, the heat exchange core 40 and the fan are at least partially exposed circumferentially, facilitating maintenance or cleaning of both.

[0069] Optionally, the first shell section 101 is provided with a notch 117, and the second shell section 106 is provided with an insert block 118; or, the second shell section 106 is provided with a notch, and the first shell section 101 is provided with an insert block.

[0070] The insert is inserted into the notch and adapted to the socket to restrict the circumferential movement of the first shell section 101 relative to the second shell section 106.

[0071] The movement of the first shell section 101 relative to the second shell section 106 is restricted by the cooperation of the notch and the insert. This design enhances the connection stability between the first shell section 101 and the second shell section 106, prevents relative rotation or displacement of the first shell section 101 and the second shell section 106 during use, and ensures long-term stable operation of the equipment.

[0072] like Figure 4 and Figure 5 As shown, when the first shell segment 101 and the second shell segment 106 are arranged sequentially along the length of the installation space, the insert block is inserted into the notch, and the first shell segment 101 can rotate relative to the second shell segment 106 in the circumferential direction of the first shell segment 101.

[0073] When the first shell segment 101 and the second shell segment 106 are arranged sequentially along the circumference of the installation space, the insert block is inserted into the notch, and the first shell segment 101 can move relative to the second shell segment 106 along the length direction of the installation space.

[0074] Optionally, such as Figure 4 and Figure 5 As shown, the first shell section 101 is provided with a first cover plate 105, which is located on the outer or inner side of the second shell section 106. The first cover plate 105 and the second shell section 106 are detachably connected. The direction closer to the axis of the mounting space is called the inner side, and the direction farther from the axis of the mounting space is called the outer side.

[0075] The first cover plate 105 is provided on the first shell segment 101 for detachable connection with the second shell segment 106, that is, the first cover plate 105 and the second shell segment 106 are detachably connected to achieve detachable connection between the first shell segment 101 and the second shell segment 106. The first cover plate 105 is provided on the outer side or the inner side of the second shell segment 106, that is, the first cover plate 105 and the second shell segment 106 have an overlapping part in the inner and outer directions, so as to facilitate the provision of the structure for detachable connection with the second shell segment 106 on the first cover plate 105, such as the snap-fit ​​part being provided on the first cover plate 105.

[0076] like Figure 5 As shown, the second shell section 106 is provided with a second cover plate 116, which is located on the outer or inner side of the first shell section 101 and is detachably connected to the first shell section 101. The direction closer to the axis of the mounting space is defined as "inner," and the direction farther from the axis of the mounting space is defined as "outer."

[0077] The second cover plate 116 is provided on the second shell section 106 for detachable connection with the first shell section 101. That is, the second cover plate 116 is detachably connected to the first shell section 101, so as to realize the detachable connection between the first shell section 101 and the second shell section 106. The second cover plate 116 is provided on the outside or inside of the first shell section 101, that is, the second cover plate 116 and the first shell section 101 have an overlapping part in the inside and outside direction, so as to facilitate the inclusion of the structure detachably connected to the first shell section 101 in the second cover plate 116, such as the snap-fit ​​part being provided in the second cover plate 116.

[0078] Optionally, if the first shell section 101 is provided with a first cover plate 105, the second shell section 106 is provided with a first mounting groove 107 that does not penetrate through the thickness direction of the second shell section 106, and the first cover plate 105 is located in the first mounting groove 107.

[0079] like Figure 5 As shown, the first cover plate 105 is located within the first mounting groove 107, and the first cover plate 105 is adapted to the first mounting groove 107, with the first cover plate 105 abutting against the bottom wall of the first mounting groove 107. By providing the first mounting groove 107, the height of the first cover plate 105 protruding from the second shell section 106 can be reduced, so that the inner or outer wall surface of the second shell section 106 with the first mounting groove 107 can be flush with the corresponding wall surface of the first shell section 101.

[0080] like Figure 5 As shown, when the second shell section 106 is provided with a second cover plate 116, the first shell section 101 is provided with a second mounting groove 102 that does not penetrate the thickness direction of the second shell section 106, and the second cover plate 116 is located in the second mounting groove 102.

[0081] The second cover plate 116 is located within the second mounting groove 102, and the second cover plate 116 is adapted to the second mounting groove 102, abutting against the bottom wall of the second mounting groove 102. By providing the second mounting groove 102, the height of the second cover plate 116 protruding from the first shell section 101 can be reduced, so that the inner or outer wall surface of the first shell section 101 with the second mounting groove 102 can be flush with the corresponding wall surface of the second shell section 106.

[0082] Optionally, such as Figure 2 As shown, the heat exchange core 40 has the same outer diameter as the fan.

[0083] On the one hand, the heat exchange core 40 has the same outer diameter as the fan, ensuring their compatibility within the housing 10. This design optimizes the uniformity of airflow, reduces airflow resistance, improves fan efficiency and heat exchange effect, and reduces noise. On the other hand, the fact that the heat exchange core 40 and the fan have the same outer diameter allows for interchangeability between them, achieving the same level of fixation within the housing 10.

[0084] Optionally, such as Figure 2 and Figure 3 As shown, when the first shell section 101 and the second shell section 106 are arranged sequentially along the length of the installation space, the first shell section 101 is provided with a first limiting part 110, and the second shell section 106 is provided with a second limiting part 111. The heat exchange core 40 and the fan abut against each other and are located between the first limiting part 110 and the second limiting part 111 to restrict the movement of the heat exchange core 40 and the fan along the length of the installation space.

[0085] This design ensures the stable installation of the heat exchange core 40 and the fan within the housing 10, preventing displacement of the heat exchange core 40 and the fan during operation, and improving the stability and safety of the equipment.

[0086] like Figure 9As shown, taking the heat exchange core 40 located in the first shell section 101 and the fan located in the second shell section 106 as an example, the end of the heat exchange core 40 away from the fan abuts against the first limiting part 110 to prevent the heat exchange core 40 from moving away from the fan; the end of the heat exchange core 40 facing the fan abuts against the fan to prevent the heat exchange core 40 from moving towards the fan and to prevent the fan from moving towards the heat exchange core 40; the end of the fan away from the heat exchange core 40 abuts against the second limiting part 111 to prevent the fan from moving away from the heat exchange core 40.

[0087] The first limiting part 110 can be a first limiting protrusion protruding inward from the first shell section 101, and the second shell section 106 can be a second limiting protrusion protruding inward from the second shell section 106.

[0088] Optionally, the heat exchange core 40 is detachably connected to the first shell section 101 or the second shell section 106 where it is located.

[0089] When the heat exchange element 40 is located in the first shell section 101, the heat exchange element 40 is detachably connected to the first shell section 101. When the heat exchange element 40 is located in the second shell section 106, the heat exchange element 40 is detachably connected to the second shell section 106.

[0090] In this way, the heat exchange core 40 can be removed from the housing 10 for replacement or cleaning, which improves the maintainability and flexibility of the equipment and reduces maintenance costs.

[0091] Optionally, the fan can be detachably connected to the first housing section 101 or the second housing section 106 where the fan is located.

[0092] When the fan is located in the first housing section 101, the fan is detachably connected to the first housing section 101. When the fan is located in the second housing section 106, the fan is detachably connected to the second housing section 106.

[0093] This allows the fan to be removed from the housing 10 for replacement or cleaning, improving the maintainability and flexibility of the equipment and reducing maintenance costs.

[0094] like Figure 5 As shown, the first shell segment 101 is the same as the second shell segment 106.

[0095] The first shell section 101 and the second shell section 106 have the same shape and structure, and are assembled to form at least part of the installation space. This design makes the manufacturing and assembly of the shell 10 simpler, reduces production costs, and improves the modularity and versatility of the equipment, allowing users to flexibly configure the position of the heat exchange core 40 and the fan according to their needs.

[0096] Optionally, the parameters of the first shell segment 101 and the second shell segment 106 are completely identical, such as shape, structure, size, material, etc.

[0097] The number of fans can be one.

[0098] like Figure 2 As shown, the number of fans can also be multiple, including a first fan 201 and a second fan 202.

[0099] The first fan 201, the second fan 202, and the heat exchange core 40 are all located within the installation space.

[0100] The first fan 201 and the second fan 202 are both connected to the first air inlet / outlet 112 and the second air inlet / outlet 113. Under the action of the first fan 201 and / or the second fan 202, air enters the installation space through one of the first air inlet / outlet 112 and the second air inlet / outlet 113 and flows out from the other of the first air inlet / outlet 112 and the second air inlet / outlet 113.

[0101] One of the first air inlet / outlet 112 and the second air inlet / outlet 113 is connected to the indoor environment, and the other of the first air inlet / outlet 112 and the second air inlet / outlet 113 is connected to the outdoor environment.

[0102] The system incorporates a first fan 201 and a second fan 202, replacing the single-fan design. Since both the first fan 201 and the second fan 202 are connected to the first air inlet / outlet 112 and the second air inlet / outlet 113, air enters the installation space through one of these inlets / outlets, exchanges heat with the heat exchange core 40, and then flows out through the other. During this process, the first fan 201 and the second fan 202 can work collaboratively, thereby increasing airflow and preventing excessive noise.

[0103] Furthermore, the inclusion of a first fan 201 and a second fan 202, meaning the fresh air unit 100 comprises multiple fans, can improve the uniformity of airflow within the installation space and enhance the heat exchange efficiency of the heat exchange core 40. It can also reduce the load on individual fans and extend the service life of the first fan 201 and the second fan 202.

[0104] The following description uses an example where the first air inlet / outlet 112 connects to the indoor environment and the second air inlet / outlet 113 connects to the outdoor environment. It can be understood that the first air inlet / outlet 112 can also connect to the outdoor environment and the second air inlet / outlet 113 can connect to the indoor environment.

[0105] Regarding the relative positions of the first fan 201, the second fan 202, and the heat exchange core 40 within the installation space, Example 1: Figure 7As shown, along the direction from the first air inlet / outlet 112 to the second air inlet / outlet 113, the first fan 201, the second fan 202 and the heat exchange core 40 are arranged in sequence.

[0106] In this setup, the first air inlet / outlet 112 connects to the indoor environment, therefore the first fan 201 and the second fan 202 are positioned close to the indoor side. Data test results show that, under the same operating conditions, this setup results in a greater intake air volume than an exhaust air volume. Intake refers to air entering the room from the second air inlet / outlet 113 (i.e., from the outside), while exhaust refers to air flowing from the room to the outside (i.e., from the first air inlet / outlet 112 to the second air inlet / outlet 113).

[0107] Example 2, such as Figure 9 As shown, along the direction from the first air inlet / outlet 112 to the second air inlet / outlet 113, the heat exchange core 40, the first fan 201 and the second fan 202 are arranged in sequence.

[0108] The second air inlet / outlet 113 connects to the outside, therefore the first fan 201 and the second fan 202 are positioned close to the outdoor side. In this configuration, under the same operating conditions of the fresh air unit 100, the air volume generated by the placement method in Exemplary 1 is greater than the air volume generated by the structure in Exemplary 2, but the placement method in Exemplary 2 will generate less noise.

[0109] Example 3: Figure 2 As shown, along the direction from the first air inlet / outlet 112 to the second air inlet / outlet 113, the first fan 201, the heat exchange core 40, and the second fan 202 are arranged in sequence.

[0110] The first fan 201 and the second fan 202 are respectively located on opposite sides of the heat exchange core 40, which can compensate for the drawbacks of high noise in Example 1 and low air volume in Example 2, and achieve a balance between noise and air volume.

[0111] Optionally, the heat exchange core 40 includes a first heat exchange section and a second heat exchange section, which are arranged sequentially along the direction from the first air inlet / outlet 112 to the second air inlet / outlet 113.

[0112] The first fan 201 and / or the second fan 202 are located between the first heat exchange section and the second heat exchange section.

[0113] One of the first fan 201 and the second fan 202 may be located between the first heat exchange section and the second heat exchange section, or both the first fan 201 and the second fan 202 may be located between the first heat exchange section and the second heat exchange section. In this case, the first heat exchange section, the first fan 201, the second fan 202, and the second heat exchange section are arranged sequentially along the direction from the first air inlet / outlet 112 to the second air inlet / outlet 113, or the first heat exchange section, the second fan 202, the first fan 201, and the second heat exchange section are arranged sequentially.

[0114] The heat exchange section is divided into a first heat exchange section and a second heat exchange section, which can further optimize the heat exchange efficiency and ensure that the air can fully exchange heat when flowing through the heat exchange core 40, thereby improving the overall performance of the system.

[0115] Optionally, the first fan 201 and / or the second fan 202 are reversible fans.

[0116] The reversible fan can change the airflow direction as needed to realize the intake and exhaust modes of the fresh air unit 100. This design enhances the flexibility of the fresh air unit 100, enabling it to adapt to different working modes, such as introducing fresh air or exhausting indoor air, further improving the applicability and efficiency of the system.

[0117] Optionally, the outer diameter of the first fan 201 is the same as that of the heat exchange core 40.

[0118] The first fan 201 has the same outer diameter as the heat exchange core 40, ensuring the matching between the first fan 201 and the heat exchange core 40 and optimizing the uniformity of airflow. This design can reduce airflow resistance, improve the efficiency of the first fan 201, and reduce noise.

[0119] Optionally, the second fan 202 has the same outer diameter as the heat exchange core 40.

[0120] The second fan 202 has the same outer diameter as the heat exchange core 40, ensuring the matching between the second fan 202 and the heat exchange core 40 and optimizing the uniformity of airflow. This design can reduce airflow resistance, improve the efficiency of the second fan 202, and reduce noise.

[0121] Optionally, the fresh air unit 100 also includes a detection module and a controller.

[0122] The detection module is located in the housing 10 and / or the installation space, and is used to detect the operating parameters or environmental parameters of the fresh air unit 100.

[0123] The controller is connected to the detection module, the first fan 201 and the second fan 202, and is used to control the operation of the first fan 201 and / or the second fan 202 according to the detection results of the detection module.

[0124] The detection module can monitor the operating parameters and / or environmental parameters of the fresh air unit 100 in real time, and automatically adjust the operation of the first fan 201 and the second fan 202 based on the detection results. This intelligent control can optimize the operating efficiency of the first fan 201 and the second fan 202, reduce energy consumption, and extend the service life of the first fan 201 and the second fan 202.

[0125] The operating parameters of the fresh air unit 100 can be the air volume and the noise level generated by the fresh air unit 100, and the environmental parameters can be the indoor temperature, outdoor temperature, indoor air quality, outdoor air quality, etc.

[0126] Optionally, the operating parameters of the fresh air unit 100 include the air volume, and the detection module includes an air volume sensor for detecting the air volume of the fresh air unit 100. The controller controls the speed of the first fan 201 and / or the second fan 202 according to the air volume.

[0127] The fan closer to the first air inlet / outlet 112 in the first fan 201 and the second fan 202 contributes more to the air volume. When the air volume detected by the air volume sensor is less than the preset air volume, increasing the speed of the fan closer to the first air inlet / outlet 112 in the first fan 201 and the second fan 202 is more effective than increasing the speed of the fan closer to the first air inlet / outlet in the first fan 201 and the second fan 202. When the air volume detected by the air volume sensor is greater than the preset air volume, decreasing the speed of the fan closer to the first air inlet / outlet 112 in the first fan 201 and the second fan 202 is more effective than decreasing the speed of the fan closer to the first air inlet / outlet in the first fan 201 and the second fan 202.

[0128] Alternatively, when the indoor air quality is poor and the outdoor air quality is good, the rotation speed of the fan closest to the first air inlet / outlet 112 in the first fan 201 and the second fan 202 can be increased to increase the amount of fresh air 100 entering the room in suction mode.

[0129] Optionally, the operating parameters of the fresh air unit 100 include the noise level generated by the fresh air unit 100, and the detection module includes a noise detection device for detecting the noise level generated by the fresh air unit 100. The controller controls the rotation speed of the first fan 201 and / or the second fan 202 according to the noise level.

[0130] The fan closer to the first air inlet / outlet 112 in the first fan 201 and the second fan 202 contributes more to the noise level. When the noise level detected by the noise detection device is greater than the preset noise level, reducing the speed of the fan closer to the first air inlet / outlet 112 in the first fan 201 and the second fan 202 is more effective than reducing the speed of the fan closer to the first air inlet / outlet 112 in the first fan 201 and the second fan 202.

[0131] Optionally, such as Figures 1 to 4As shown, the housing 10 includes a first housing segment 101 and a second housing segment 106.

[0132] The second shell section 106 is detachably connected to the first shell section 101; wherein, the heat exchange core 40 is disposed within one of the first shell section 101 and the second shell section 106, and the first fan 201 and / or the second fan 202 is disposed within the other of the first shell section 101 and the second shell section 106. In other words, the heat exchange core 40 is disposed within one of the first mounting space 108 and the second mounting space 109, and the first fan 201 and / or the second fan 202 is disposed within the other of the first mounting space 108 and the second mounting space 109.

[0133] In this configuration, the heat exchange core 40 can be repaired and replaced by disassembling the first shell section 101 and the second shell section 106, and the first fan 201 and / or the second fan 202 located in the other shell section 101 and the second shell section 106 can be maintained and replaced, thereby improving the maintainability and service life of the equipment.

[0134] Optionally, such as Figure 2 As shown, the housing 10 also includes a third housing segment 114, which is connected to the second housing segment 106 or the first housing segment 101. One of the first fan 201 and the second fan 202 is located within the other of the first housing segment 101 and the second housing segment 106, and the other of the first fan 201 and the second fan 202 is located within the third housing segment 114.

[0135] like Figure 2 As shown, when the third shell section 114 is connected to the second shell section 106, the third shell section 114, the second shell section 106, and the first shell section 101 are arranged sequentially along the length of the installation space; as shown... Figure 7 As shown, when the third shell section 114 is connected to the first shell section 101, the third shell section 114, the first shell section 101, and the second shell section 106 are arranged sequentially along the length of the installation space. Whether the third shell section 114 is connected to the second shell section 106 or to the first shell section 101 depends on the position of the first fan 201 or the second fan 202 located in the third shell section 114 within the new air unit 100. For example, if the first fan 201, the second fan 202, and the heat exchange core 40 are arranged sequentially along the direction from the first air inlet / outlet 112 to the second air inlet / outlet 113, and the second fan 202 is located in the first shell section 101, then the first fan 201 is located in the third shell section 114, the heat exchange core 40 is located in the second shell section 106, and the third shell section 114 is connected to the first shell section 101.

[0136] The connection between the third shell section 114 and the first shell section 101, or the connection between the third shell section 114 and the second shell section 106, can be a detachable connection or a fixed connection.

[0137] like Figure 7 As shown, one of the first fan 201 and the second fan 202 is located in one of the first shell section 101 and the second shell section 106, and the other of the first fan 201 and the second fan 202 is located in the third shell section 114. This provides more installation flexibility for the first fan 201, the second fan 202 and the heat exchange core 40, and the layout of the first fan 201, the second fan 202 and the heat exchange core 40 can be adjusted according to actual needs to optimize airflow and heat exchange efficiency.

[0138] The third shell section 114 defines the third mounting space 115, and the first mounting space 108, the second mounting space 109 and the third mounting space 115 together form the mounting space.
