Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an air conditioner. Background Technology

[0002] As people's living standards improve, air conditioners have gradually entered thousands of households, becoming an important household appliance. Among these appliances, the electrical control box, as the control unit in the air conditioner's operation, is particularly important for its stability. However, during air conditioner operation, because various components are integrated on the electrical control board, the temperature inside the control box gradually rises after power is applied. When the temperature inside the control box becomes too high, it will damage the electrical control board and multiple components. While related technologies include heat dissipation devices within the control box, these devices are complex in structure, occupy a large installation space, have high investment costs, and offer poor heat dissipation, directly affecting the stability of the air conditioner's operation.

[0057] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0058] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0059] An air conditioner 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings. The type of air conditioner 100 is not limited; for example, it can be an integrated air conditioning unit, such as a portable air conditioner, a window air conditioner, etc., or it can be the indoor unit of a split air conditioner, such as a wall-mounted air conditioner or a floor-standing air conditioner, etc.

[0060] like Figures 1-3 As shown, an air conditioner 100 according to an embodiment of the present invention includes: a housing 1, a heat exchanger component (not shown), a fan component 2, an electrical control box component 3, and a cooling system 4 for cooling the electrical control box component 3. Specifically, the housing 1 has an air inlet 11 and an air outlet 12, and an air duct connecting the air inlet 11 and the air outlet 12. The fan component 2 and the electrical control box component 3 are disposed within the housing 1, and the heat exchanger component and the impeller 22 of the fan component 2 are disposed within the air duct. That is, the heat exchanger component, the fan component 2, and the electrical control box component 3 are all disposed within the housing 1, so that the housing 1 provides good protection for the heat exchanger component, the fan component 2, and the electrical control box component 3 located within the housing 1, thereby improving the stability of the air conditioner 100.

[0061] Both the air inlet 11 and the air outlet 12 are connected to the indoor space. The fan component 2 includes a volute 21, a motor (not shown), and a fan wheel 22. The volute 21 defines a portion of the air outlet duct, and the fan wheel 22 is located inside the volute 21. The motor is connected to the fan wheel 22 to drive its rotation. Therefore, after the air conditioner 100 is started, driven by the fan component 2 (i.e., the motor drives the fan wheel 22 to rotate), the air in the indoor space can enter the duct through the air inlet 11 and flow along the duct towards the air outlet 12, ultimately being discharged into the indoor space through the air outlet 12. This achieves forced air circulation between the duct and the indoor space. As the airflow flows from the air inlet 11 towards the air outlet 12, it comes into contact with the heat exchanger component located in the duct, allowing the heat exchanger component to regulate the temperature of the flowing air. The air regulated by the heat exchanger component can then be discharged from the duct through the air outlet 12 and into the indoor space, gradually regulating the temperature of the indoor space. During the operation of the air conditioner 100, the electrical control components (not shown) in the electrical control box 3 generate heat when powered on. Therefore, the cooling system 4 can effectively reduce the temperature of the electrical control box 3, keeping it within a safe temperature range. This prevents damage to the electrical control components due to excessively high temperatures, thus improving the stability and reliability of the electrical control box 3. Furthermore, it prevents interference with other components inside the casing 1 caused by excessively high temperatures in the electrical control box 3, further enhancing the stability of the air conditioner 100.

[0062] Furthermore, the cooling system 4 includes a liquid storage box 41, a circulation pipe 42, and a water pump 43. Both the liquid storage box 41 and the water pump 43 are connected in series to the circulation pipe 42. That is, the liquid storage box 41, the water pump 43, and the circulation pipe 42 can form a connected water flow channel. For example, the inlet of the water pump 43 can be connected to the outlet of the liquid storage box 41, and the outlet of the water pump 43 can be connected to one end of the circulation pipe 42. The other end of the circulation pipe 42 is connected to the inlet of the liquid storage box 41. The liquid storage box 41 stores coolant. The water pump 43 can draw coolant from the liquid storage box 41 through its inlet and discharge it into the circulation pipe 42. The coolant can flow within the circulation pipe 42 and then be discharged back into the liquid storage box 41 through its other end, thus achieving the circulation of the coolant. The coolant can be water or other liquids; no specific limitations are imposed here.

[0063] Among them, such as Figure 4 and Figure 5As shown, the circulation pipe 42 includes a first pipe section 42a and a second pipe section 42b. At least a portion of the first pipe section 42a is disposed in the electrical control box component 3 to cool the electrical control box component 3, and at least a portion of the second pipe section 42b extends into the air duct. That is, during the operation of the air conditioner 100, the electrical control components in the electrical control box component 3 generate heat after being powered on. For example, the temperature of the electrical control box component 3 can be detected by a temperature monitoring module. When the temperature of the electrical control box component 3 exceeds a threshold, the water pump 43 can be controlled to drive the coolant in the liquid storage box 41 to circulate in the circulation pipe 42. When the coolant flows through the portion of the first pipe section 42a disposed in the electrical control box component 3, the heat generated by the electrical control box component 3 can be transferred to the coolant in the first pipe section 42a to reduce the temperature of the electrical control box component 3 and prevent high temperature from affecting the stability and reliability of the electrical control components. As the coolant flows, the coolant that absorbs heat from the electrical control box component 3 flows from the first pipe section 42a. The air conditioner operates by blowing air through the fan 22 into the second pipe section 42b. During operation, the fan 22 drives the airflow within the duct. Therefore, when the coolant flows to the portion of the second pipe section 42b located within the duct, the airflow within the duct contacts this portion, effectively reducing the temperature of the coolant. In other words, the airflow during the operation of the air conditioner 100 can cool the coolant, thus eliminating the need for a device to cool the coolant. This simplifies the cooling system 4, reducing its investment cost and installation space. Furthermore, the simple structure of the cooling system 4 makes its subsequent maintenance easier.

[0064] Furthermore, the cooled coolant, driven by the water pump 43, can flow from the second pipe section 42b back into the first pipe section 42a to absorb heat from the electrical control box component 3 again. In other words, during the operation of the air conditioner 100, the coolant, driven by the water pump 43, circulates between the first pipe section 42a and the second pipe section 42b, continuously cooling the electrical control box component 3 to prevent damage to the electrical control components due to excessive temperature, thus improving the stability and reliability of the electrical control box component 3. In addition, it prevents interference from excessively high temperatures in the electrical control box 31 with other components inside the casing 1, further enhancing the stability of the air conditioner 100.

[0065] According to an embodiment of the air conditioner 100 of the present invention, the cooling system 4 includes a liquid storage box 41, a circulation pipe 42, and a water pump 43. The liquid storage box 41 and the water pump 43 are both connected in series to the circulation pipe 42. The circulation pipe 42 includes a first pipe section 42a and a second pipe section 42b. At least a portion of the first pipe section 42a is disposed in the electronic control box component 3 to cool the electronic control box component 3. At least a portion of the second pipe section 42b extends into the air duct. The airflow in the air duct can effectively reduce the temperature of the coolant in the second pipe section 42b. The water pump 43 drives the coolant to circulate between the first pipe section 42a and the second pipe section 42b, continuously cooling the electronic control box component 3 to prevent damage to the electronic control components due to excessive temperature, thus improving the stability and reliability of the electronic control box component 3. Furthermore, it can prevent interference with other components inside the casing 1 due to excessively high temperature of the electronic control box 31, further improving the stability of the air conditioner 100.

[0066] According to some embodiments of the present invention, the control box component 3 includes a control box 31 and an electronic control component disposed within the control box 31. The control box 31 provides better protection for the electronic control component, improving its stability and reliability. Furthermore, the control box 31 effectively prevents heat generated by the electronic control component after power-on from overflowing, thus avoiding interference with other components within the housing 1 and improving the stability of the air conditioner 100. At least a portion of the first pipe section 42a is located within the control box 31, and this portion constitutes a cooling section 421. That is, coolant can flow through the cooling section 421 into the interior of the control box 31, bringing the coolant closer to the electronic control component as it flows through the cooling section 421. Therefore, by placing the cooling section 421 within the control box 31, the path of heat radiated from the electronic control component to the coolant is shortened, improving the cooling effect of the coolant within the cooling section 421 on the interior of the control box 31.

[0067] Furthermore, the cooling section 421 is spaced apart from the electronic control components. That is, there is no contact between the cooling section 421 and the electronic control components. This effectively avoids the risk of interference between the cooling section 421 and the electronic control components. For example, as the air conditioner 100 operates for an extended period, the heat generated by the electronic control components accumulates inside the electronic control box 31, resulting in a high temperature inside the electronic control box 31. Therefore, when the cooler coolant enters the cooling section 421, the high-temperature gas comes into contact with the cooling section 421, which may cause condensation to form on the outer wall of the cooling section 421. Therefore, by separating the cooling section 421 from the electronic control components, the condensation generated on the cooling section 421 can be effectively prevented from spreading to the electronic control components, thereby avoiding the risk of short circuits in the electronic control components due to contact between condensation and the electronic control components. This is beneficial for improving the stability and reliability of the electronic control box component 3 and the air conditioner 100. In a specific example, the first pipe section 42a is a metal pipe with good thermal conductivity. Therefore, by separating the cooling section 421 from the electronic control component, the safe distance between the electronic control component and the cooling section 421 can be well guaranteed, preventing the risk of electric arc when the distance between the electronic control component and the cooling section 421 is too close, which is conducive to ensuring the stability and reliability of the electronic control component.

[0068] Furthermore, the electronic control assembly includes an electronic control board, which is positioned opposite to the cooling section 421. This effectively shortens the heat transfer path between the electronic control board and the cooling section 421, and ensures that the coolant in the cooling section 421 can quickly and efficiently absorb the heat released by the electronic control board after it is powered on, thereby improving the cooling efficiency of the cooling system 4 for the electronic control box component 3. In a specific example, the projection of the electronic control board on the reference plane is located within the outer periphery of the projection of the cooling section 421 on the reference plane, further enhancing the cooling effect of the cooling section 421 on the electronic control board.

[0069] Furthermore, the electronic control components include component assemblies, such as terminal blocks. These component assemblies and the electronic control board are arranged along the length of the electronic control box 31, allowing them to fully utilize the space in the length direction of the box, thus reducing the width and thickness dimensions of the box. The cooling section 421 extends in an S-shape along the length of the box 31, which, compared to an S-shape along the width direction, improves the density of the cooling section 421. This results in a larger heat exchange area within the cooling section 421, thereby increasing the efficiency of the coolant in the cooling section 421 in absorbing heat from the box 31 and enhancing the cooling effect of the cooling section 421 on the box 31.

[0070] According to some optional embodiments of the present invention, the cooling section 421 is opposite to the electronic control board. During the operation of the air conditioner 100, the electronic control board integrates components such as capacitors and resistors, resulting in significant heat generation and a high temperature in the mounting area of ​​the electronic control board within the electronic control box 31. Therefore, by positioning the cooling section 421 opposite to the electronic control board, the cooling effect of the cooling section 421 on the mounting area of ​​the electronic control board can be better ensured, thereby effectively preventing overheating and damage to the electronic control board and improving the stability and reliability of the electronic control box component 3.

[0071] According to some optional embodiments of the present invention, the cooling section 421 is opposite to the electronic control board and component assemblies, which can better increase the area of ​​the cooling section 421 arranged within the electronic control box 31. The coolant within the cooling section 421 can absorb the heat generated by the electronic control board and component assemblies and discharge it from the electronic control box 31, further improving the cooling effect of the cooling system 4 on the electronic control box 31. Furthermore, the arrangement density of the portion of the cooling section 421 opposite to the electronic control board is greater than the arrangement density of the portion of the cooling section 421 opposite to the component assemblies. During the operation of the air conditioner 100, the control board generates significant heat due to the integrated components such as capacitors and resistors. The heat generated by the components is relatively small compared to that of the control board. In other words, the arrangement density of the cooling section 421 can be flexibly set according to the heat distribution within the control box 31. For example, the arrangement density of the cooling section 421 can be increased in areas with higher heat within the control box 31 to improve the cooling effect of the cooling section 421 on areas with higher temperatures. Conversely, the arrangement density of the cooling section 421 can be decreased in areas with lower heat. This ensures the cooling effect of the cooling section 421 while shortening its length, thereby saving on the production cost of the cooling section 421.

[0072] In addition, in a specific example, the control board is provided with a first mounting area and a second mounting area. The first mounting area is provided with components such as capacitors and resistors, and the second mounting area is provided with components such as diodes. After the control board is powered on, the heat generation efficiency of the first mounting area is greater than that of the second mounting area, and the arrangement density of the cooling section 421 opposite to the first mounting area is greater than that of the cooling section 421 opposite to the second mounting area.

[0073] According to some embodiments of the present invention, such as Figure 4 and Figure 6 As shown, the electrical control box 31 includes a detachably connected box body 311 and a box cover 312. The electrical control components are housed inside the box body 311, which significantly reduces the difficulty of assembling, disassembling, and maintaining the electrical control components. For example, the box cover 312 can be removed from the box body 311, and the electrical control components can be installed inside the box body 311, or maintenance operations such as inspection and repair can be performed on the electrical control components inside the electrical control box 31.

[0074] Furthermore, the first pipe segment 42a is disposed on the cover 312, and the cooling section 421 is fixed to the inner wall of the cover 312. That is, the cooling section 421 is disposed on the side of the cover 312 facing the electronic control components. As a result, the difficulty of assembling and disassembling the first pipe segment 42a and the cover 312 can be significantly reduced. For example, the cover 312 can be removed from the body 311, the first pipe segment 42a can be fixed to the cover 312, and then the cover 312 can be assembled onto the body 311. This allows for a larger installation space between the first pipe segment 42a and the cover 312, and facilitates the removal of the first pipe segment 42a from the cover 312 when cleaning is required. In addition, the cooling section 421 can better avoid occupying the installation space inside the housing 311, so as to ensure the installation space of the electronic control components. Furthermore, when maintenance operations such as inspection and repair of the electronic control components are required, after the cover 312 is removed from the housing 311, the cooling section 421 can move away from the housing 311 along with the cover 312, thereby avoiding the cooling section 421 from blocking the electronic control components and reducing the maintenance difficulty of the electronic control components.

[0075] According to some optional embodiments of the present invention, the housing 311 and the cover 312 are arranged horizontally, and the cooling section 421 is located on one side of the electronic control component in the horizontal direction. This effectively separates the electronic control component and the cooling section 421. In a specific example, the cover 312 is located on the front side of the housing 311, the electronic control component is disposed on the bottom wall of the housing 311 facing the cover 312, and the cooling section 421 is disposed on the side wall of the cover 312 facing the housing 311, i.e., the inner wall. This effectively avoids the risk of interference between the cooling section 421 and the electronic control component. For example, it effectively prevents condensate generated on the cooling section 421 from spreading to the electronic control component, thereby avoiding the risk of short circuit in the electronic control component due to contact between condensate and the electronic control component, which is beneficial to improving the stability and reliability of the electronic control housing component 3 and the air conditioner 100. In addition, when the first pipe section 42a is a metal pipe, the safe distance between the electronic control component and the cooling section 421 can be better guaranteed, preventing risks such as electric arcs when the electronic control component and the cooling section 421 are too close, which is conducive to ensuring the stability and reliability of the electronic control component.

[0076] According to some alternative embodiments of the present invention, such as Figure 6 and Figure 9As shown, two first through holes 313 are formed on the cover 312. The two ends of the first pipe segment 42a pass through the two first through holes 313 and extend to the outside of the cover 312. The two ends of the second pipe segment 42b are connected to the two ends of the first pipe segment 42a. That is, the first pipe segment 42a, except for the part of the cooling section 421, extends to the outside of the cover 312, and the second pipe segment 42b is located outside the control box 31. This allows for communication between the cooling section 421 located in the control box 31 and the second pipe segment 42b outside the control box 31, which can effectively reduce the difficulty of connecting the first pipe segment 42a and the second pipe segment 42b, and save the installation space occupied by the circulation pipe 42 in the control box 31. Secondly, the first pipe segment 42a can fill the two first through holes 313 well, which can effectively prevent the heat overflow in the control box 31 from affecting other components near the control box component 3, thus improving the stability of the air conditioner 100. In addition, by making a hole in the cover 312, the structural strength of the cover 312 is minimally affected, and the structural strength of the box body 311 can be better avoided, which is conducive to improving the overall structural strength of the electrical control box 31.

[0077] In a specific example, such as Figure 10 and Figure 11 As shown, hollow connectors 424 are provided at both ends of the first pipe section 42a, and hollow assembly heads 425 are provided at both ends of the second pipe section 42b. The connectors 424 and the assembly heads 425 are detachably connected, which helps to reduce the difficulty of connecting the first pipe section 42a and the second pipe section 42b, thereby improving the assembly efficiency of the cooling system 4.

[0078] According to some alternative embodiments of the present invention, such as Figure 8 and Figure 12 As shown, the inner wall of the cover 312 is provided with a first fixing member 32 for fixing the cooling section 421. The first fixing member 32 includes a first connecting part 321 and a first limiting part 322. The first connecting part 321 is connected to the inner wall of the cover 312, and the first limiting part 322 is arc-shaped with its opening facing the cover 312. One end of the first limiting part 322 is connected to the first connecting part 321, and the other end of the first limiting part 322 is a free end. The cooling section 421 passes through the space defined by the first limiting part 322 and the inner wall of the cover 312. Therefore, the connection between the cooling section 421 and the cover 312 can be better guaranteed, and the installation and disassembly of the cooling section 421 can be easily achieved, which helps to reduce the difficulty of assembling and disassembling the first pipe section 42a and the cover 312.

[0079] In a specific example, the first limiting part 322 is elastically deformable in the direction toward or away from the lid 312. Therefore, the first limiting part 322 can be pushed to move away from the lid 312, increasing the distance between the free end of the first limiting part 322 and the lid 312. This facilitates the insertion of the cooling section 421 between the first limiting part 322 and the lid 312 through the gap between the free end of the first limiting part 322 and the inner wall of the lid 312. The first limiting part 322 then returns to its original shape in the direction closer to the lid 312, and the free end of the first limiting part 322 and the lid 312... The gap between the two sections is reduced to fix the first pipe section 42a to the cover 312. When it is necessary to remove the cooling section 421 from the cover 312, the first limiting part 322 is pushed to move away from the cover 312, so that the gap between the free end of the first limiting part 322 and the cover 312 is increased. This makes it easier to remove the cooling section 421 from the gap between the first limiting part 322 and the cover 312 through the gap between the free end of the first limiting part 322 and the inner wall of the cover 312, so that the first pipe section 42a can be removed from the cover 312, which helps to reduce the difficulty of assembling and disassembling the first pipe section 42a.

[0080] In a specific example, the first limiting part 322 is deformable. For example, the first limiting part 322 is a deformable metal sheet. Therefore, by moving the first limiting part 322, the first limiting part 322 can be separated from the lid 312. At this time, the first fixing member 32 is in a released state, and the cooling section 421 is placed between the first limiting part 322 and the lid 312. By pressing the first limiting part 322 towards the lid 312, the first limiting part 322 can fit along the outer periphery of the cooling section 421 and adhere to the outer periphery of the cooling section 421. At this time, the first fixing member 32 is in a locked state, thereby realizing the limiting effect of the first fixing member 32 on the cooling section 421, which helps to improve the fixing effect of the first fixing member 32 on the cooling section 421. In addition, to ensure the structural strength and flame retardancy of the electrical control box 31, the electrical control box 31 can be a sheet metal part. Therefore, the assembly difficulty of the first fixing part 32 made of metal and the box cover 312 is low. For example, the first fixing part 32 and the box cover 312 can be connected by welding, bolt structure or other methods.

[0081] According to some embodiments of the present invention, such as Figure 5 , Figure 13 and Figure 15As shown, the second pipe section 42b includes a heat dissipation section 422 located inside the air duct and a connecting section 423 located outside the air duct. The connecting section 423 connects the heat dissipation section 422 and the first pipe section 42a. That is, the coolant that absorbs heat in the first pipe section 42a flows into the heat dissipation section 422 through the connecting section 423, and the coolant in the heat dissipation section 422 is cooled by the airflow in the air duct. In addition, at least a portion of the connecting section 423 runs along the outer wall of the electrical control box 31, making the internal layout of the air conditioner 100 neater and reducing the risk of interference between the part of the connecting section 423 that is attached to the electrical control box 31 and other components. The layout is reasonable. In a specific example, such as Figure 5 and Figure 7 As shown, the first pipe section 42a is provided on the cover 312, and the connecting section 423 is adapted to run along the outer wall of the box body 311, so that after the first pipe section 42a and the second pipe section 42b are separated, it is easy to remove the cover 312 from the box body 311.

[0082] Furthermore, such as Figure 16 and Figure 17 As shown, the outer wall of the electrical control box 31 is provided with a second fixing member 33 for fixing the connecting section 423, thereby ensuring a secure connection between the connecting section 423 and the box body 311. Specifically, the second fixing member 33 includes a second connecting part 331 and a second limiting part 332. The second connecting part 331 is connected to the outer wall of the box body 311, and the second limiting part 332 is arc-shaped with its opening facing the box body 311. One end of the second limiting part 332 is connected to the second connecting part 331, and the other end of the second limiting part 332 is a free end. The connecting section 423 passes through the space defined by the second limiting part 332 and the outer wall of the box body 311. This allows for easy installation and disassembly of the connecting section 423, reducing the difficulty of assembling and disassembling the connecting section 423 and the box body 311.

[0083] In a specific example, the second limiting part 332 is elastically deformable in the direction toward or away from the box body 311. Therefore, the second limiting part 332 can be pushed to move away from the box body 311, increasing the distance between the free end of the second limiting part 332 and the box body 311. This facilitates the insertion of the connecting segment 423 through the gap between the free end of the second limiting part 332 and the inner wall of the box body 311 between the second limiting part 332 and the box body 311. The second limiting part 332 then recovers its deformation in the direction closer to the box body 311. The gap between the free end of the tube and the housing 311 is reduced to fix the second tube segment 42b to the housing 311. When it is necessary to remove the connecting segment 423 from the housing 311, the second limiting part 332 is pushed to move away from the housing 311, thereby increasing the gap between the free end of the second limiting part 332 and the housing 311. This makes it easier to remove the connecting segment 423 from the gap between the second limiting part 332 and the housing 311 through the gap between the free end of the second limiting part 332 and the inner wall of the housing 311, which helps to reduce the difficulty of assembling and disassembling the connecting segment 423.

[0084] In a specific example, the second limiting part 332 is deformable. For example, the second limiting part 332 is a deformable metal sheet. Therefore, by moving the second limiting part 332, the second limiting part 332 can be spaced apart from the box body 311. At this time, the second fixing member 33 is in a released state, and the connecting segment 423 is placed between the second limiting part 332 and the box body 311. By pressing the second limiting part 332 toward the box body 311, the second limiting part 332 can fit along the outer periphery of the connecting segment 423 and adhere to the outer periphery of the connecting segment 423. At this time, the second fixing member 33 is in a locked state, thereby realizing the limiting effect of the second fixing member 33 on the connecting segment 423, which helps to improve the fixing effect of the second fixing member 33 on the connecting segment 423. In addition, to ensure the structural strength and flame retardancy of the electrical control box 31, the electrical control box 31 can be a sheet metal part. Therefore, the assembly difficulty of the second fixing part 33 made of metal and the box body 311 is low. For example, the second fixing part 33 and the box body 311 can be connected by welding, bolt structure or other methods.

[0085] According to some embodiments of the present invention, such as Figure 13As shown, the fan component 2 includes a volute 21 that defines a portion of the air duct. An impeller 22 is located within the volute 21. The portion of the second pipe section 42b located within the air duct is a heat dissipation section 422. The heat dissipation section 422 is located within the volute 21. This effectively reduces the distance between the heat dissipation section 422 and the impeller 22, resulting in a larger airflow at the location of the heat dissipation section 422 within the air duct. This improves the heat dissipation effect of the fan component 2 on the heat dissipation section 422, thereby ensuring the cooling effect of the cooling system 4 on the electrical control box component 3. The fan component 2 can be located upstream or downstream of the heat exchanger component; no specific limitation is made here. Here, upstream and downstream are relative to the airflow duct within the air duct.

[0086] In a specific example, the air duct extends roughly in the vertical direction. The fan component 2 is located below the heat exchanger component. The fan component 2 includes a volute 21 and a fan wheel 22 disposed within the volute 21. The volute 21 forms an upward opening located upstream of the heat exchanger component and is disposed opposite to the heat exchanger component. The electrical control box component 3 is disposed below the heat exchanger component. The electrical control box component 3 is located in front of the opening of the volute 21 and adjacent to the volute 21. This can effectively reduce the distance between the heat exchanger component and the fan component 2, which is beneficial for shortening the pipe running distance of the circulation pipe 42 and saving the production cost of the circulation pipe 42.

[0087] According to some alternative embodiments of the present invention, such as Figure 18 and Figure 19 As shown, two second through holes 211 are formed on the volute 21. The two ends of the second pipe segment 42b pass through the two second through holes 211 respectively and extend to the outside of the volute 21. Therefore, by having the second pipe segment 42b directly pass through the volute 21, the pipe travel distance of the second pipe segment 42b can be shortened, which helps to reduce the cost of the second pipe segment 42b and simplifies the layout of the cooling system 4. In a specific example, the second pipe segment 42b is a flexible hose, for example, it can be a plastic pipe. This can reduce the installation difficulty of the second pipe segment 42b, and the shape of the second pipe segment 42b can be flexibly adjusted according to the installation position. For example, the shape can be flexibly adjusted according to the structural requirements of the installation position, such as bending, etc., to reduce the pipe travel difficulty of the second pipe segment 42b. In addition, the outer peripheral wall of the flexible hose can be interference-fitted with the inner peripheral wall of the second through hole 211, thereby preventing the airflow in the duct from being lost through the second through hole 211.

[0088] According to some alternative embodiments of the present invention, such as Figure 13 and Figure 15As shown, the heat dissipation section 422 is located at the air outlet end of the volute 21. This effectively separates the heat dissipation section 422 from the impeller 22, thus preventing the heat dissipation section 422 from occupying the installation space of the impeller 22 within the volute 21, and also preventing interference between the impeller 22 and the heat dissipation section 422 during rotation. This improves the stability and reliability of the cooling system 4 and the fan component 2.

[0089] Furthermore, such as Figure 2 and Figure 15 As shown, the air outlet 12 forms the front sidewall of the housing 1. The volute 21 defines the air outlet chamber 212 of the impeller 22 and the air outlet chamber 213. The air outlet chamber 213 is located downstream of the air outlet chamber 212. That is, the impeller 22 is adapted to drive the air in the air outlet chamber 212 to flow into the air outlet chamber 213. The impeller 22 is located in the air outlet chamber 212. The air outlet end of the air outlet chamber 213 is open upwards. The front sidewall of the air outlet chamber 213 extends forward at an angle from bottom to top. The electrical control box 31 assembly is located on the front side of the air outlet chamber 213, and the heat dissipation section 422 is adjacent to the front sidewall of the air outlet chamber 213. Thus, while ensuring that the airflow can flow to the air outlet 12 located on the front side, the air volume of the heat dissipation section 422 in the air outlet chamber 213 is relatively large, so as to improve the heat dissipation effect of the fan component 2 on the heat dissipation section 422, thereby ensuring the cooling effect of the cooling system 4 on the electrical control box component 3.

[0090] According to some alternative embodiments of the present invention, such as Figure 3 and Figure 4 As shown, both the water pump 43 and the liquid storage box 41 are mounted on the outer wall of the volute 21. This significantly reduces the difficulty of assembling and disassembling the water pump 43 and the liquid storage box 41, and facilitates the maintenance of the water pump 43 and the liquid storage box 41.

[0091] Further optional, such as Figure 20 As shown, the outer wall of the volute 21 is provided with a retaining ring 23 for fixing the water pump 43 and a mounting bracket 24 for mounting the liquid storage box 41. This significantly reduces the difficulty of installing and positioning the water pump 43 and the liquid storage box 41, enabling rapid installation of both and ensuring a secure connection between the water pump 43, the liquid storage box 41, and the volute 21, thereby improving the stability and reliability of the cooling system 4. In a specific example, the retaining ring 23 is fitted onto the outer periphery of the water pump 43, forming an opening opposite to the direction of the volute 21. The mounting bracket 24 contains a mounting cavity 241 for accommodating the liquid storage box 41, thus enhancing the protective performance of the mounting bracket 24 for the liquid storage box 41.

[0092] Optionally, the water pump 43 is located above the liquid storage box 41, allowing the liquid storage box 41 and the water pump 43 to fully utilize the vertical installation space on the outer wall of the volute 21, resulting in a compact layout. Furthermore, the outlet of the liquid storage box 41 can be located on its top wall, facilitating communication with the water pump 43 while effectively preventing coolant overflow from the liquid storage box 41. When the cooling system 4 is stopped and the water pump 43 is de-energized, any residual coolant in the water pump 43 can flow back into the liquid storage box 41 for storage. Additionally, both the water pump 43 and the liquid storage box 41 are located between the volute 21 and the electrical control box component 3. This allows the water pump 43 and the liquid storage box 41 to fully utilize the space between the volute 21 and the electrical control box component 3, and reduces the distance between the water pump 43 and the liquid storage box 41 and the volute 21 and the electrical control box component 3, thereby shortening the travel distance of the circulation pipe 42 and saving on the cost of the circulation pipe 42.

[0093] According to some embodiments of the present invention, the first pipe segment 42a is a metal pipe, which can improve the thermal conductivity of the first pipe segment 42a, thereby improving the efficiency of heat transfer from the electrical control box component 3 to the coolant in the first pipe segment 42a, which is beneficial to improving the cooling effect of the cooling system 4 on the electrical control box component 3 and achieving rapid cooling of the electrical control box component 3. Furthermore, the second pipe segment 42b is a flexible hose, which can significantly reduce the installation difficulty of the second pipe segment 42b, and the shape of the second pipe segment 42b can be flexibly adjusted according to the installation position. For example, the shape can be flexibly adjusted according to the structural requirements of the installation position, such as bending, etc., to reduce the difficulty of pipe routing of the second pipe segment 42b.

[0094] According to some embodiments of the present invention, the two ends of the first pipe segment 42a and the two ends of the second pipe segment 42b are detachably connected. Therefore, independent production of the first pipe segment 42a and the second pipe segment 42b is possible, which improves the production efficiency of the first pipe segment 42a and the second pipe segment 42b. Furthermore, the separate arrangement of the first pipe segment 42a and the second pipe segment 42b reduces the difficulty of shaping the circulation pipe 42 and facilitates subsequent individual cleaning or replacement maintenance operations of the first pipe segment 42a and the second pipe segment 42b. In a specific example, the two ends of the first pipe segment 42a are respectively provided with hollow connectors 424, and the two ends of the second pipe segment 42b are respectively provided with hollow assembly heads 425. The connectors 424 and the assembly heads 425 are detachably connected, which reduces the difficulty of connecting the first pipe segment 42a and the second pipe segment 42b, thereby improving the assembly efficiency of the cooling system 4.
