Description

Technical Field

[0001] The present disclosure relates to a suppression structure for a heat absorption and release component, and more particularly to a suppression structure for a heat absorption and release component of a vehicle. Background Art

[0002] Conventionally, a heat absorption and release assembly, air conditioning components, and electrical components are placed within the front cabin space of a vehicle, for example, under the engine hood or motor cover. When the heat absorption and release assembly is placed horizontally within the front cabin, for example, it is positioned near vehicle air conditioning components (e.g., the compressor, accumulator, expansion valve, piping, etc.), or near electrical components (e.g., motors, direct current-to-direct current converters (DC-DC converters), relays, controllers, power distribution boxes, electric water pumps, electronic fans, sensors, etc.).

[0003] Air blown from the heat absorption and release assembly can easily directly hit the air conditioning unit and electrical components. This can easily exchange heat with the air on the surface of the air conditioning unit, potentially reducing the cooling and heating efficiency of the air conditioning unit and degrading the performance and efficiency of the vehicle's thermal management system. Furthermore, rainwater or condensation can easily pass through the heat absorption and release assembly and be blown onto surrounding electrical components or air conditioning units, potentially reducing the durability of these components' waterproofing and other features. Summary of the Invention

[0004] The present application is made in view of the above situation, and its purpose is to provide a suppression structure for a heat absorption and release component, which can suppress the air blown out from the heat absorption and release component from blowing directly to the air-conditioning component and electrical parts, and can also prevent rainwater or condensed water discharged from the heat absorption and release component from blowing to the surrounding electrical parts or air-conditioning components.

[0005] In order to achieve the above-mentioned purpose, the suppression structure for the heat absorption and release component involved in the present application is provided with a heat absorption and release component in the front cabin of the vehicle or the rear space of the vehicle, and is also provided with electrical components and / or air-conditioning components for air conditioning in the vehicle interior. The suppression structure is configured to suppress the air discharged from the heat absorption and release component from reaching the air-conditioning component and / or the electrical components.

[0006] According to such a structure, the suppression structure for the heat absorption and release component can prevent the air discharged from the heat absorption and release component from being blown directly to the air conditioning component and / or electrical components, and can also prevent rainwater or condensation water discharged from the heat absorption and release component from being blown to the surrounding electrical components or air conditioning components, thereby improving the durability of electrical components, etc.

[0007] In a possible embodiment, when the heat absorption and release component, the electrical components, and the air conditioning component are arranged in the front cabin, an opening for the air exhausted from the heat absorption and release component to be discharged from the front cabin is provided on a vehicle lower cover or a vehicle side cover.

[0008] According to such a configuration, the position of the opening through which the air exhausted from the heat absorption and release module is discharged to the front cabin can be flexibly set.

[0009] In a possible embodiment, when the heat absorption and release component, the electrical components, and the air conditioning component are arranged in the rear space of the vehicle, an opening for the air exhausted from the heat absorption and release component to be discharged into the rear space of the vehicle is provided on any one of the vehicle lower cover, the vehicle side cover, and the vehicle rear cover.

[0010] According to such a configuration, the position of the opening through which the air exhausted from the heat absorption and release module is exhausted to the rear space of the vehicle can be flexibly set.

[0011] In a possible embodiment, the suppression structure is an air guide member provided on the outer peripheral side of the heat absorption and release component.

[0012] According to such a structure, the air guide plays an air guiding role and can prevent the air discharged from the heat absorption and release component from being blown directly to the air conditioning component and / or electrical components. It can also prevent rainwater or condensation water discharged from the heat absorption and release component from being blown to the surrounding electrical components or air conditioning components, thereby improving the durability of electrical components, etc.

[0013] In a possible embodiment, the suppression structure is a structure having an opening for allowing air exhausted from the heat absorption and release component to be exhausted into the front cabin or the rear space of the vehicle, and the opening is provided within a projection area of ​​the heat absorption and release component along an axial direction of the heat absorption and release component.

[0014] According to such a structure, by arranging the opening in the projection area of ​​the heat absorption and release component along the axial direction of the heat absorption and release component, the distance between the heat absorption and release component and the opening can be shortened, that is, the exhaust path of the heat absorption and release component can be shortened, so that the air exhausted from the heat absorption and release component is immediately discharged from the opening to the front cabin or the rear space of the vehicle, thereby improving the exhaust efficiency and effectively suppressing the air volume leading to the air-conditioning component.

[0015] In a possible embodiment, the suppression structure is a structure in which the uppermost edge of the air outlet of the heat absorption and release component is located below or at the same height as the lowermost part of the air conditioning component and / or the electrical component.

[0016] According to such a structure, by making the uppermost edge of the air outlet of the heat absorption and release component be located below or at the same height as the lowermost part of the air conditioning component and / or the electrical components, the air discharged from the heat absorption and release component can be prevented from being blown directly to the air conditioning component and / or the electrical components, and the rainwater or condensed water discharged from the heat absorption and release component can be prevented from being blown to the surrounding electrical components or air conditioning components, thereby improving the durability of electrical components, etc.

[0017] In a possible embodiment, the heat absorption and release component includes a heat exchanger, an air supply device, a first shell and a second shell, the heat exchanger is used to perform heat exchange on the air sucked into the front cabin or the rear space of the vehicle, and the air after heat exchange through the heat exchanger is blown out through the air supply device, the first shell is located between the heat exchanger and the air supply device, the first shell and the second shell are joined to form a space for accommodating the air supply device, the first shell includes a through-portion that passes through the first shell from both ends of the first shell opposite to each other in the axial direction of the heat absorption and release component, the through-portion is used to guide the air passing through the heat exchanger to the air supply device, and the air blown out by the air supply device passes through the first shell and The air is blown out from the opening formed between the second shells, and the air guide is a plate extending from the outer wall of the first shell along the direction of leaving the first shell and approaching the air supply device. The first distance between the proximal end of the air guide and the heat exchanger is less than the second distance between the lower end surface of the first shell facing the air supply device and the heat exchanger, and the distal end of the air guide is located below or at the same height position as the lowest part of the air-conditioning component and / or the electrical parts. The proximal end of the air guide is the end of the air guide close to the first shell, and the distal end of the air guide is the end of the air guide away from the first shell. The air guide is at least arranged on the side of the first shell closest to the air-conditioning component and / or the electrical parts.

[0018] According to such a structure, by making the distal end of the air guide member be located below or at the same height as the lowest part of the air-conditioning component and / or the electrical components, the air guide member is at least arranged on the side of the first shell closest to the air-conditioning component and / or the electrical components, so that the air guide member can prevent most of the air blown out from the air supply device from blowing directly onto the air-conditioning component and / or the electrical components, and can also prevent rainwater or condensation water discharged from the air supply device from blowing onto the surrounding electrical components or air-conditioning components, thereby improving the durability of electrical components, etc.

[0019] In a possible embodiment, the distal end of the air guide moves away from the air supply device in a radial direction of the air supply device as it moves away from the first shell in an axial direction of the air supply device.

[0020] According to such a configuration, the air guide is formed into a skirt structure, and can effectively guide the flow of air blown out from the air supply device without hindering the flow.

[0021] In a possible embodiment, the lower edge of the air guide for guiding the air to be blown out is located below or at the same height as the lowest part of the air conditioning component and / or the electrical component.

[0022] According to such a structure, the air guide can further effectively prevent the exhaust gas from the heat absorption and release component from being blown directly to the air-conditioning component and / or electrical components, and can also prevent rainwater or condensed water discharged from the heat absorption and release component from being blown to the surrounding electrical components or air-conditioning components, thereby improving the durability of electrical components, etc.

[0023] In a possible embodiment, the air guide is arranged around the air supply device of the heat absorption and release component, and the lower edge of the air guide for guiding the air to be blown out is located below or at the same height as the lowest part of the air conditioning component and / or the electrical components.

[0024] According to such a configuration, the amount of air directly blown from the air blowing device to the air conditioning unit and / or electrical components can be further reduced.

[0025] In a possible embodiment, a plurality of air guide members are intermittently arranged around the air supply device.

[0026] According to such a structure, it is not necessary to provide an air guide around the entire circumference of the air supply device, and the weight of the entire device can be reduced.

[0027] In a possible embodiment, the air guide is continuously arranged around the air supply device.

[0028] According to such a configuration, the amount of air directly blown from the air blowing device to the air conditioning unit and / or electrical components can be reduced more effectively.

[0029] In a possible embodiment, in a structure in which the air guide is continuously arranged around the air supply device, the maximum distance in the horizontal direction between the air guide and the outer edge of the air supply device facing the air guide is greater than 14.4% and less than 100% of the diameter of the air supply device.

[0030] Since the closer the air guide is to the air supply device, the greater the resistance of the air guide to the air blown out from the air supply device and the greater the noise, according to such a structure, the air guide can be set at an appropriate distance relative to the air supply device, which can significantly reduce the resistance of the air guide to the air blown out from the air supply device and reduce noise.

[0031] In a possible embodiment, an opening is provided in the projection area of ​​the outer contour of the air guide or the air guide and the heat absorption and release component as a whole along the axial projection of the air supply device possessed by the heat absorption and release component, so that the air blown out by the air supply device flows out of the front cabin or the rear space of the vehicle through the opening.

[0032] According to such a structure, by arranging an opening for the air blown out by the air supply device to flow out of the front cabin or the rear space of the vehicle within the projection area of ​​the outer contour of the air guide member or the air guide member and the heat absorption and release component as a whole along the axial direction of the air supply device, the distance between the air supply device and the opening can be shortened, that is, the exhaust path of the air supply device can be shortened, so that the air discharged from the air supply device is immediately discharged from the opening to the front cabin or the rear space of the vehicle, thereby improving the exhaust efficiency and effectively suppressing the air volume leading to the air-conditioning component and / or electrical components.

[0033] In a possible embodiment, the air guide extends from the outer wall of the first shell to the lower cover of the vehicle, and the air guide has at least a portion located between the air conditioning component and the electrical parts and an opening for discharging air discharged from the heat absorption and release component into the front cabin or the rear space of the vehicle.

[0034] This structure effectively guides air exhausted from the heat absorption and release unit to the opening for direct exhaust. This further ensures that the exhausted air does not directly reach the air conditioning unit and / or electrical components, improving exhaust efficiency. It also effectively prevents rainwater or condensed water discharged from the air supply device from reaching surrounding electrical components or the air conditioning unit, improving the durability of these components.

[0035] In a possible embodiment, the air guide extends from the outer wall of the first shell all the way around to a position that completely surrounds the opening.

[0036] According to such a structure, all the air discharged from the heat absorption and release component can be effectively guided to the opening position and discharged directly without being blown onto the air-conditioning component and / or electrical components, which can improve the exhaust efficiency and further effectively prevent rainwater or condensed water discharged from the air supply device from being blown onto the surrounding electrical components or air-conditioning components, thereby improving the durability of electrical components, etc.

[0037] In one possible embodiment, the heat absorption and release assembly includes a heat exchanger, an air supply device, a first shell, and a second shell. The heat exchanger is used to perform heat exchange on air sucked into the rear space of the vehicle. The air after heat exchange through the heat exchanger is blown out through the air supply device. An opening for the air discharged from the heat absorption and release assembly to be discharged into the rear space of the vehicle is provided at any one of a vehicle lower cover, a vehicle side cover, and a vehicle rear cover. The first shell is located between the heat exchanger and the air supply device. The first shell and the second shell are joined to form a space for accommodating the air supply device. The heat exchanger is located closer to the vehicle lower cover relative to the first shell. The first shell includes through portions that penetrate the first shell from opposite ends of the first shell in the axial direction of the heat absorption and release assembly. The through portions are used to guide the air passing through the heat exchanger to the air supply device. The air blown out by the air supply device is blown out through an opening formed between the first shell and the second shell. The air guide extends from the outer wall of the first shell to a position that surrounds the opening.

[0038] According to such a structure, since the air inlet of the duct that guides air into the heat exchanger is set near the vehicle's lower cover when the heat absorption and release component is set in the rear space of the vehicle, by setting the heat exchanger of the heat absorption and release component to be located closer to the vehicle's lower cover relative to the first shell, a shorter structure can be set to effectively reduce wind resistance and pressure loss, and improve heat exchange efficiency.

[0039] In a possible embodiment, an air inlet of the heat exchanger faces the vehicle lower cover.

[0040] According to such a structure, wind resistance and pressure loss can be further reduced, and heat exchange efficiency can be improved.

[0041] In a possible embodiment, the air conditioning assembly includes at least a compressor, piping, and an expansion valve.

[0042] According to such a structure, the heat loss of the air conditioning unit can be effectively reduced by the suppression structure for the heat absorption and release unit, thereby improving the performance and efficiency of the air conditioning unit and improving the durability of electrical parts, etc.

[0043] In a possible embodiment, the electrical components include any one of a motor, a DC-DC converter, a relay, a controller, a distribution box, an electric water pump, an electronic fan, and a sensor.

[0044] According to such a structure, the suppression structure used in the heat absorption and release component can effectively suppress air from blowing onto electrical parts, thereby improving the performance, efficiency and durability of the electrical parts.

[0045] In a possible embodiment, the axial direction of the heat absorption and release component is inclined relative to the vehicle lower cover.

[0046] According to such a structure, the range of the projection area can be increased and the design flexibility of the opening can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In addition, in the following embodiments, the same reference symbols are sometimes used for parts that are identical or equivalent to those described in the previous embodiments, and repeated descriptions are omitted. In addition, in the embodiments, when only a part of a structural element is described, the structural elements described in the previous embodiments can be applied to the other parts of the structural element. In the following embodiments, as long as there is no particular hindrance to the combination, the various embodiments can be partially combined with each other even without special instructions.

[0083] <First embodiment>

[0084] First, refer to Figures 1 to 7 A first embodiment will be described.

[0085] A front compartment 1 is provided under the engine hood or motor hood at the front of the vehicle, and air flows from outside the vehicle into the front compartment 1. Heat absorbing and releasing components 2, an air conditioning component 3 for air conditioning the vehicle interior, and electrical components 5 are arranged in the front compartment 1.

[0086] The air conditioning unit 3 comprises at least a compressor, piping, and an expansion valve (none of which are shown), and some units may also include a liquid accumulator. For the purposes of this disclosure, any component that, combined with the compressor, piping, and expansion valve, forms a single unit for air conditioning within the vehicle interior and that affects the air conditioning performance of the air conditioning unit 3 through heat exchange with the air is considered part of the air conditioning unit 3. Furthermore, various electrical components 5 are located within the front compartment 1.

[0087] The various electrical components 5 include, for example, a motor, a DC-DC converter, a relay, a controller, a distribution box, an electric water pump, an electronic fan, and sensors. In the present disclosure, the motor, the DC-DC converter, the relay, the controller, the distribution box, the electric water pump, the electronic fan, and sensors, in addition to the air conditioning unit 3, are all included in the structure of the electrical components 5.

[0088] exist Figure 2 The figure schematically shows an integrated structure of the air conditioning assembly 3 and the electrical parts 5, but this is only for the convenience of illustration. The air conditioning assembly 3 and the electrical parts 5 can of course be independently separated and arranged in the front cabin 1 or the rear space 4 of the vehicle.

[0089] In addition, the vehicle has a vehicle rear space 4. When the vehicle has a trunk, the vehicle rear space 4 includes the trunk and the space under the trunk floor. When the vehicle does not have a trunk but has a space connected to the interior of the vehicle behind the last row of seats, the vehicle rear space 4 includes the space and the space under the floor of the space.

[0090] While the heat absorption and release assembly 2, air conditioning assembly 3, and electrical components 5 of this embodiment are all disposed in the front compartment 1, they may also all be disposed in the vehicle rear space 4. When the heat absorption and release assembly 2 is disposed in the front compartment 1, the heat absorption and release assembly suppression structure of this embodiment is used to suppress wind from blowing toward the air conditioning assembly 3 and electrical components 5 within the front compartment 1. When the heat absorption and release assembly 2 is disposed in the vehicle rear space 4, the heat absorption and release assembly suppression structure of this embodiment is used to suppress wind from blowing toward the air conditioning assembly 3 and electrical components 5 within the vehicle rear space 4. In addition, the structure may also be as follows: only the heat absorption and release component 2 and the air-conditioning component 3 are provided in the front cabin 1 or the rear space 4 of the vehicle, and the suppression structure for the heat absorption and release component is used to suppress the wind from blowing toward the air-conditioning component 3 in the front cabin 1 or the rear space 4 of the vehicle; or only the heat absorption and release component 2 and the electrical components 5 are provided in the front cabin 1 or the rear space 4 of the vehicle, and the suppression structure for the heat absorption and release component is used to suppress the wind from blowing toward the electrical components 5 in the front cabin 1 or the rear space 4 of the vehicle, and this is also the case in subsequent embodiments.

[0091] In this embodiment, when the heat absorption and release assembly 2, the electrical components 5, and the air conditioning assembly 3 are arranged in the front cabin 1, the opening for the air discharged from the heat absorption and release assembly 2 to be discharged from the front cabin 1 (refer to FIG. Figure 9 、 11 , 12 shown in the openings 9A, 10A) are provided on the vehicle lower cover 9 or the vehicle side cover 10; when the heat absorption and release component 2, the electrical components 5, and the air conditioning component 3 are arranged in the vehicle rear space 4, the opening for the air discharged from the heat absorption and release component 2 to be discharged from the vehicle rear space 4 (reference Figure 9 、 11 , 12 , 13 are provided in any one of the vehicle lower cover 9 , the vehicle side cover 10 and the vehicle rear cover 11 .

[0092] The suppression structure for the heat absorption and release module of the first embodiment is an air guide 7 provided on the outer peripheral side of the heat absorption and release module 2 , and is configured to suppress air exhausted from the heat absorption and release module 2 from reaching the air conditioning module 3 and the electrical components 5 .

[0093] The heat absorption and release assembly 2 includes a heat exchanger 20 , a fan 21 (air supply device), a first housing 22 and a second housing 23 .

[0094] The heat exchanger 20 is used to perform heat exchange on the air drawn into the front cabin 1 or the vehicle rear space 4. The air that has undergone heat exchange in the heat exchanger 20 is blown out by the fan 21. In this embodiment, the fan 21 is a vortex fan, but the fan is not limited to a turbofan and may also be another air supply device such as a multi-blade blower.

[0095] The first housing 22 is located between the heat exchanger 20 and the fan 21. The first housing 22 and the second housing 23 are joined to form a space for accommodating the fan 21. The first housing 22 includes through-portions 24 extending through the first housing 22 at opposite ends thereof in the axial direction of the heat absorption and release assembly 2. The through-portions 24 are used to guide air passing through the heat exchanger 20 toward the fan 21. The air blown out by the fan 21 is then blown out through an opening 25 formed between the first housing 22 and the second housing 23.

[0096] See also Figure 2 Specifically, the heat exchanger 20 is fixed to the axial end of the first housing 22, away from the fan 21. Four upper columns 221 extend from the four corners of the lower end surface 22a of the first housing 22, which has a generally rectangular outer contour, toward the second housing 23. Four lower columns 231 extend from the four corners of the upper end surface 23a of the second housing 23, which has a generally rectangular outer contour, toward the first housing 22. The lower ends of the four upper columns 221 and the upper ends of the four lower columns 231 are joined, for example, by welding, to form a housing assembly having a generally rectangular outer contour. Thus, openings 25 are formed on the four side surfaces of the housing assembly, surrounded by the lower end surface 22a of the first housing 22, the upper columns 221, the upper end surface 23a of the second housing 23, and the lower columns 231. The fan 21 is housed within the interior space of the first and second housings 22 and 23, which is surrounded by the four openings 25. More specifically, the fan 21 is housed in a housing recess formed on the upper end surface 23a of the second housing 23, and the motor shaft of the motor 100 disposed below the second housing 23 is connected to the fan shaft of the fan 21 through a hole provided through the housing recess. Thus, the driving force of the motor 100 can be transmitted to the fan 21 to drive the fan 21 to rotate. In addition, in the present embodiment, the housing assembly formed by joining the first housing 22 and the second housing 23 has a substantially rectangular outer contour, but the specific structure and shape of the first housing 22 and the second housing 23 are not limited to the structure and shape specifically described in the present embodiment, and may be any structure and shape. For example, the housing assembly formed by joining the first housing 22 and the second housing 23 or the housing formed by integrally molding the first housing 22 and the second housing 23 may have a substantially cylindrical outer contour.

[0097] In this embodiment, the heat exchanger 20, first housing 22, fan 21, and second housing 23 are arranged in order from top to bottom along the axial direction of the heat absorption and release assembly 2. In a preferred embodiment, the heat exchanger 20, first housing 22, fan 21, and second housing 23 are coaxially arranged. In this embodiment, the axial direction of the heat absorption and release assembly 2 is also the axial direction of the fan 21.

[0098] The air guide 7 disposed on the outer periphery of the heat absorption and release assembly 2 is more specifically disposed on the outer periphery of the first housing 22. However, disposing the air guide 7 on the outer periphery of the first housing 22 is merely an example, and the air guide 7 may be disposed on the outer periphery of the heat absorption and release assembly 2, for example, on the outer periphery of the heat exchanger 20.

[0099] In the present embodiment, the air guide member 7 is a plate extending from the outer wall of the first housing 22 in a direction away from the first housing 22 and toward the fan 21. The air guide member 7 has a proximal end 7a and a distal end 7b. The proximal end 7a (upper end) of the air guide member 7 is the end of the air guide member 7 close to the first housing 22, and the distal end 7b (lower end) of the air guide member 7 is the end of the air guide member 7 away from the first housing 22. More specifically, in the present embodiment, the distal end 7b of the air guide member 7 moves away from the fan 21 in the radial direction of the fan 21 as it moves away from the first housing 22 in the axial direction of the fan 21.

[0100] See also Figure 2 The first distance H1 between the proximal end 7a of the air guide 7 and the heat exchanger 20 is less than the second distance H2 between the lower end surface 22a of the first shell 22 facing the fan 21 and the heat exchanger 20, that is, the lower end surface 22a of the first shell 22, which is the uppermost part of the opening 25, is located below the proximal end 7a of the air guide 7. By satisfying H1≤H2, it can be ensured that the air flowing out of the opening 25 will not leak between the air guide 7 and the outer wall of the first shell 22.

[0101] In this embodiment, the air guide 7 only needs to be provided on at least one side of the first shell 22 that is closest to the air conditioning component 3 and the electrical components 5. For example, the air guide 7 is provided on the first shell 22 corresponding to the opening 25 facing the air conditioning component 3 and the electrical components 5 among the four openings 25. Alternatively, the air guide 7 is provided on the first shell 22 corresponding to the opening 25 facing the air conditioning component 3 and the electrical components 5 and its two adjacent openings 25 among the four openings 25. When the outer contour of the shell assembly formed by assembling the first shell 22 and the second shell 23 is, for example, not a roughly rectangular parallelepiped shape but a roughly cylindrical shape, the case where the air guide 7 is provided on at least one side of the first shell 22 that is closest to the air conditioning component 3 and the electrical components 5 means that the air guide 7 is provided within a range of 1 / 4 of the outer contour of the shell assembly facing the air conditioning component 3 and the electrical components 5.

[0102] In another possible embodiment, the air guide 7 is disposed around the fan 21, and the air guide 7 is intermittently disposed around the fan 21, for example, four air guides that are not connected to each other are disposed at four corners corresponding to the four openings 25. In another possible embodiment, the air guide 7 is disposed around the fan 21, and is continuously disposed around the fan 21.

[0103] See also Figure 7 In this embodiment, the maximum horizontal distance H3 between the air guide 7, which is continuously arranged around the fan 21, and the outer edge 21a of the air guide 7 facing the fan 21 is greater than 14.4% and less than 100% of the diameter of the fan 21. In this embodiment, the portion of the air guide 7 that is farthest from the outer edge 21a of the air guide 7 facing the fan 21 is the distal end 7b of the air guide 7. The closer the air guide 7 is to the fan 21, the greater the resistance to the air blown out from the fan 21 and the louder the noise. The farther the air guide 7 is from the fan 21, the more space it occupies in the cabin. Therefore, by setting the distance 14.4% ≤ H3 ≤ 100%, this embodiment can position the air guide 7 at an appropriate distance from the fan 21, significantly reducing the resistance of the air guide 7 to the air blown out from the fan 21 and reducing noise.

[0104] In this embodiment, it is preferred that Figure 2 As shown, the lower edge of the air guide 7, through which air is directed, i.e., the distal end 7b of the air guide 7, is located at the same height as the lowest point A of the air conditioning unit 3 and electrical components 5. More preferably, the lower edge of the air guide 7, i.e., the distal end 7b of the air guide 7, is located below the lowest point A of the air conditioning unit 3 and electrical components 5. However, the lower edge of the air guide 7, through which air is directed, does not necessarily have to be at the same height as or below the lowest point A of the air conditioning unit 3 and electrical components 5. Alternatively, the lower edge of the air guide 7, through which air is directed, may be located above the lowest point A of the air conditioning unit 3 and electrical components 5. The lowest point A of the air conditioning unit 3 and electrical components 5 refers to the lowest point of the air conditioning unit 3 and electrical components 5 as a whole. Furthermore, in a configuration comprising only the air conditioning unit 3, the lowest point A refers to the lowest point of the air conditioning unit 3; in a configuration comprising only the electrical components 5, the lowest point A refers to the lowest point of the electrical components 5.

[0105] In addition, when the lower edge of the air guide 7 for guiding the air to be blown out is located above the lowest part A of the air conditioning unit 3 and the electrical components 5, it is preferred that the lower edge of the air guide 7 for guiding the air to be blown out, i.e., the distal end 7b, is located above the lowest part A of the air conditioning unit 3 and the electrical components 5 and the imaginary extension surface of the air guide 7 does not contact the air conditioning unit 3 and the electrical components 5. Thus, the air guide 7 can also prevent the air blown out from the fan 21 from being blown directly to the air conditioning unit 3 and the electrical components 5. The so-called imaginary extension surface of the air guide 7 is an imaginary surface extending along the outer contour of the air guide 7 itself to the lower cover 9 of the vehicle. For example, in Figure 4In the case where the air guide 7 shown is a conical surface, the imaginary extension surface of the air guide 7 is an imaginary surface extending along the conical shape to the vehicle undercover 9. Because the extension direction of this imaginary extension surface is roughly consistent with the direction of air blowing out of the air guide 7, this imaginary extension surface prevents contact with the air conditioning unit 3 and the electrical components 5. Therefore, even if the lower edge of the air guide 7, i.e., the distal end 7b, from which the air is blown out, is located above the lowest part A of the air conditioning unit 3 and the electrical components 5, the air blown out from the fan 21 can be prevented from being blown directly onto the air conditioning unit 3 and the electrical components 5.

[0106] When the heat absorption and release assembly 2 is operating, air is introduced from the exterior of the vehicle into the heat exchanger 20 through the air duct. All of the air that has undergone heat exchange in the heat exchanger 20 is directed through the through-hole 24 to the fan 21, where it is blown radially by the fan 21 and flows out through the four openings 25. The outflowing air is guided by the air guide 7 in a direction that prevents it from directly hitting the air conditioning assembly 3 and the electrical components 5, and ultimately flows out of the front cabin 1 through the openings provided in the vehicle undercover forming the bottom surface of the front cabin 1. Furthermore, in the preferred embodiment of this embodiment, the distal end 7b of the air guide 7 is located at the same height as the lowest portion A of the air conditioning assembly 3 and the electrical components 5. This effectively prevents the air blown out by the fan 21 from being directly blown onto the air conditioning assembly 3 and the electrical components 5, and also prevents outdoor rainwater or condensed water in the front cabin 1 from passing through the heat exchanger 20 and the fan 21 and being blown onto the surrounding electrical components 5 and the air conditioning assembly 3.

[0107] Below, refer to Figures 4-6 , structures 1 to 3 of the air guide member 7 continuously provided around the fan 21 are described. Figures 4-6 In the structure, the air guide member 7 is a skirt structure formed by a plate and surrounding the fan 21.

[0108] (Structure 1 of air guide)

[0109] See also Figure 4 The air guide 7 of structure 1 forms a conical surface structure that surrounds the fan 21 and is continuously provided on the outer peripheral side of the first housing 22. Specifically, the air guide 7 corresponding to each of the four side surfaces of the first housing 22 is a flat plate structure, and the distal end 7b of the air guide 7 on each side surface moves away from the fan 21 in the radial direction of the fan 21 as it moves away from the first housing 22 in the axial direction of the fan 21. The four flat plates of the air guide 7 corresponding to the four side surfaces are joined to form a square conical surface structure.

[0110] (Structure 2 of air guide)

[0111] See also Figure 5The air guide 7 of structure 2 consists of, from top to bottom, a conical portion 71 connected to the first housing 22, a curved portion 72 continuous with the conical portion 71, and a prismatic portion 73 continuous with the curved portion 72. The conical portion 71 has the same structure as the air guide 7 of structure 1. More specifically, the prismatic portion 73 is formed as a square prism, and the curved portion 72 is a structure connecting the conical portion 71 and the prismatic portion 73 via a curved surface.

[0112] (Structure 3 of air guide)

[0113] See also Figure 6 The air guide member 7 of the structure 3 is composed of an upper rounded corner portion 74 and a lower prism portion 75 from top to bottom. The lower prism portion 75 is more specifically formed as a square prism structure, and the upper rounded corner portion 74 is a structure that connects the first shell 22 and the lower prism portion 75 with a rounded corner.

[0114] The skirt structures of Structures 1 to 3 of the air guide member can smoothly guide radial wind blown out from the fan 21 to the opening of the vehicle undercover.

[0115] The above describes a specific structural example of the air guide 7 of the first embodiment. The air guide 7 of the first embodiment is a plate extending from the outer wall of the first housing 22 in a direction away from the first housing 22 and toward the fan 21, and the distal end 7b of the air guide 7 moves away from the fan 21 in the radial direction of the fan 21 as it moves away from the first housing 22 in the axial direction of the fan 21. However, the air guide 7 is not limited to this. The air guide 7 can be of any shape as long as it can prevent the air discharged from the heat absorption and release component 2 from reaching the air conditioning component 3 and / or the electrical component 5. For example, the air guide 7 can also be a structure in which the distal end 7b of the air guide 7 moves away from the first housing 22 in the axial direction of the fan 21 and approaches the fan 21 in the radial direction of the fan 21. In addition, the air guide 7 does not necessarily have to be a plate. For example, the air guide 7 can also be an air guide component formed by assembling multiple parts.

[0116] <Second embodiment>

[0117] Below, refer to Figure 8A , the second embodiment is described, and the differences between the second embodiment and the first embodiment are mainly described. The same symbols are marked for the same contents as the first embodiment, and repeated descriptions are omitted.

[0118] The heat absorption and release component suppression structure of the second embodiment is configured as follows: an opening 9A of the vehicle undercover 9 is disposed within a projected area X of the heat absorption and release component 2 projected onto the vehicle undercover 9 along the axial direction of the heat absorption and release component 2, so that air exhausted from the heat absorption and release component 2 flows out of the front cabin 1 through the opening 9A. The fact that the opening 9A is disposed within the projected area X also includes a case where the opening 9A substantially overlaps with the projected area X. Furthermore, in the second embodiment, as in the first embodiment, the heat absorption and release component 2, the air conditioning component 3, and / or the electrical components 5 may all be disposed within the vehicle rear space 4, and the heat absorption and release component suppression structure is configured to suppress wind from blowing toward the air conditioning component 3 and / or the electrical components 5 within the vehicle rear space 4.

[0119] Specifically, the opening 9A of the vehicle undercover 9 is disposed within a projection area X, which is a projection of the heat absorption and release assembly 2, including the heat exchanger 20, the fan 21, the first housing 22, and the second housing 23, along the axial direction of the heat absorption and release assembly 2, onto the vehicle undercover 9. In this embodiment, the axial direction of the fan 21 (the axial direction of the heat absorption and release assembly 2) is substantially perpendicular to the vehicle undercover 9. Preferably, the opening 9A of the vehicle undercover 9 is disposed within a projection area X, which is a projection of the fan 21 along the axial direction of the fan 21 onto the vehicle undercover 9. By disposing the opening 9A within the projection area X, the distance between the heat absorption and release assembly 2 and the opening 9A can be shortened, allowing air exhausted from the fan 21 to be immediately exhausted through the opening 9A. This shortens the exhaust path of the heat absorption and release assembly, improves exhaust efficiency, and effectively reduces the amount of air directly blown onto the air conditioning assembly 3 and the electrical components 5.

[0120] In the second embodiment, the opening 9A is provided in the projection area of ​​the heat absorption and release component 2 along the axial direction of the heat absorption and release component 2 onto the vehicle lower cover 9. However, in the second embodiment, the opening 10A may be provided in the projection area of ​​the heat absorption and release component 2 along the axial direction of the heat absorption and release component 2 onto the vehicle side cover 10 (the opening 10A and the vehicle side cover 10 refer to the projection area of ​​the heat absorption and release component 2 along the axial direction of the heat absorption and release component 2). Figure 11 ), it is also possible that the opening 11A is set in the projection area of ​​the heat absorption and release component 2 along the axial direction of the heat absorption and release component 2 to the vehicle rear cover plate 11 (the opening 11A and the vehicle side cover plate 11 are referenced Figure 11 ).

[0121] That is, the suppression structure of the second embodiment is an opening for the air exhausted from the heat absorption and release component 2 to be discharged into the front cabin 1 or the vehicle rear space 4. The opening is arranged in the projection area where the heat absorption and release component 2 is projected along the axial direction of the heat absorption and release component 2. The projection can be a projection onto the vehicle lower cover 9, or a projection onto the vehicle side cover 10 or the vehicle rear cover 11. That is, it can be a structure in which the axial direction of the heat absorption and release component 2 is directed toward the vehicle side cover 10 or the vehicle rear cover 11.

[0122] (Variation 1 of the Second Embodiment)

[0123] Next, refer to Figure 8B Modification 1 of the second embodiment will be described.

[0124] The difference between the modified example 1 of the second embodiment and the second embodiment is that the modified example 1 of the second embodiment is provided with the air guide member 7 arranged around the fan 21 of the first embodiment, and the opening 9A of the vehicle lower cover 9 is arranged to project the outer contour of the air guide member 7 or the air guide member 7 and the heat absorption and release component 2 as a whole along the axial direction of the fan 21 into the projection area X of the vehicle lower cover 9, so that the air blown out by the fan 21 flows out of the front engine compartment 1 through the opening 9A.

[0125] The so-called outer contour of the air guide member 7 is projected onto the vehicle lower cover plate 9 along the axial direction of the fan 21. When the air guide member 7 is continuously arranged around the fan 21, the projection area X is obtained by projecting the continuous outer edge of the air guide member 7 along the axial direction of the fan 21 onto the vehicle lower cover plate 9. When the air guide member 7 is discontinuously arranged around the fan 21, the continuous outer contour obtained by connecting the discontinuous outer edges of the air guide member 7 is projected onto the vehicle lower cover plate 9 along the axial direction of the fan 21.

[0126] See also Figure 8B The so-called projection area X of the air guide 7 and heat absorption and release assembly 2 as a whole projected along the axial direction of the fan 21 onto the vehicle undercover 9 is the maximum range of the air guide 7 and heat absorption and release assembly 2 projected along the axial direction of the fan 21 onto the vehicle undercover 9. Furthermore, this structure is also applicable to structures where the air guide 7 is only provided on the side of the first housing 22 closest to the air conditioning assembly 3 and electrical components 5, or where the air guide 7 is not provided around the fan 21.

[0127] Furthermore, in this first variation, the axial direction of the fan 21 (the axial direction of the heat absorption and release assembly 2) is tilted relative to the vehicle undercover 9. This increases the extent of the projected area X and enhances the design flexibility of the opening 9A. However, in this first variation, the axial direction of the fan 21 is not necessarily tilted relative to the vehicle undercover 9; the axial direction of the fan 21 can also be perpendicular to the vehicle undercover 9. Furthermore, the configuration in which the axial direction of the fan 21 is tilted relative to the vehicle undercover 9 can also be applied to the first embodiment and the third embodiment described below.

[0128] According to variant example 1 of the second embodiment, the distance between the heat absorption and release component 2 and the opening 9A can also be shortened, that is, the exhaust path of the heat absorption and release component 2 can be shortened, and the wind blown out by the fan 21 can be effectively guided to the opening 9A in the projection area X through the air guide 7.

[0129] Similarly, in Modification 1 of the second embodiment, an opening (opening 10A in the vehicle-side hood 10 or opening 11A in the vehicle rear hood 11) may be provided within a projection area X, which is a projection of the outer contour of the air guide 7 or the air guide 7 and heat absorption and release assembly 2 as a whole, along the axial direction of the fan 21 included in the heat absorption and release assembly 2. This allows air blown by the fan 21 to flow out of the front cabin 1 or the vehicle rear space 4 through these openings. In other words, the axial direction of the heat absorption and release assembly 2 may be directed toward the vehicle-side hood 10 or the vehicle rear hood 11.

[0130] (Variation 2 of the Second Embodiment)

[0131] Next, refer to Figure 9 Modification 2 of the second embodiment will be described. Modification 2 of the second embodiment differs from Modification 1 in that, in Modification 2 of the second embodiment, the air guide 7 extends from the outer wall of the first housing 22 to the vehicle lower cover 9, and the air guide 7 has at least a portion located between the air conditioning unit 3 and the electrical components 5 and the opening 9A of the vehicle lower cover 9, preferably as shown in FIG. Figure 9 As shown, the air guide 7, which is continuously arranged around the fan 21, extends from the outer wall of the first housing 22 to a position that completely surrounds the opening 9A of the vehicle undercover 9. In other words, all the air blown out of the fan 21 is guided by the air guide 7, which extends to the vehicle undercover 9 and completely surrounds the opening 9A, and flows out of the front compartment 1 through the opening 9A. This structure completely prevents the air blown out of the heat absorption and release module 2 from being blown onto the air conditioning module 3 and the electrical components 5.

[0132] However, the structure in which the air guide 7 extends from the outer wall of the first shell 22 to the vehicle lower cover 9, and the air guide 7 has at least a portion located between the air conditioning component 3 and the electrical parts 5 and the opening 9A of the vehicle lower cover 9 is not only applicable to the air guide 7 arranged around the fan 21. In the structure in which the air guide 7 is not arranged around the fan 21, such as when the air guide 7 is only arranged on the side of the first shell 22 closest to the air conditioning component 3 and the electrical parts 5, as long as the air guide 7 extends from the outer wall of the first shell 22 to the vehicle lower cover 9, and the air guide 7 separates the air conditioning component 3 and the electrical parts 5 from the opening 9A of the vehicle lower cover 9 (that is, the air guide 7 has at least a portion located between the air conditioning component 3 and the electrical parts 5 and the opening 9A of the vehicle lower cover 9), it can also effectively prevent the air blown out from the heat absorption and release component 2 from being blown to the air conditioning component 3 and the electrical parts 5.

[0133] Furthermore, in Variation 2 of the second embodiment, the vehicle side cover 10 or the vehicle rear cover 11 may be provided with an opening 10A for air outflow, and the air guide 7 may simply extend to the vehicle undercover 9 and separate the opening 10A or 11A from the air conditioning unit 3 and the electrical components 5. Specifically, the air guide 7 may extend from the outer wall of the first housing 22 to the vehicle undercover 9, and the air guide 7 may at least have a portion located between the air conditioning unit 3 and the electrical components 5 and the openings (openings 9A, 10A, 11A) through which air exhausted from the heat absorption and release unit 2 is discharged into the front cabin 1 or the vehicle rear space 4.

[0134] <Third embodiment>

[0135] Next, refer to Figure 10 The third embodiment will be described, focusing mainly on the differences between the third embodiment and the first embodiment. The same reference numerals are used for the same contents as those in the first embodiment, and duplicate descriptions are omitted.

[0136] The third embodiment differs from the first embodiment in that the suppression structure is a structure in which the uppermost edge of the air outlet of the heat absorption and release unit 2 is located below or at the same height as the lowermost portion A of the air conditioning unit 3 and the electrical component 5 .

[0137] More specifically, in the third embodiment, see Figure 10 The suppression structure is a structure in which the uppermost edge of the opening 25 (i.e., the air outlet) formed by the lower end surface 22a of the first housing 22, the upper column 221, the upper end surface 23a of the second housing 23, and the lower column 231 (in this embodiment, the lower end surface 22a of the first housing 22) is located at the same height as the lowest portion A of the air conditioning unit 3 and the electrical components 5. More preferably, the opening 25 is located below the lowest portion A of the air conditioning unit 3 and the electrical components 5. The uppermost edge of the air outlet of the heat absorption and release component 2 refers to the uppermost edge of the outlet through which the air exhausted from the heat absorption and release component 2 flows out of the heat absorption and release component 2. The opening 25 formed by the lower end surface 22a of the first housing 22, the upper column 221, the upper end surface 23a of the second housing 23, and the lower column 231 is merely a specific example of such an air outlet.

[0138] In the third embodiment, there is no air guide, but since the uppermost edge of the air outlet of the heat absorption and release component 2 is located below or at the same height as the lowermost part A of the air conditioning component 3 and the electrical component 5, it is also possible to prevent the air blown out from the heat absorption and release component 2 from being blown directly to the air conditioning component 3 and the electrical component 5.

[0139] (Modification of the Third Embodiment)

[0140] A variation of the third embodiment combines the structures of the first and second embodiments. Specifically, in this variation, an air guide 7 is provided, and the uppermost edge of the air outlet of the heat absorption and release assembly 2 is positioned below or at the same height as the lowest portion A of the air conditioning assembly 3 and the electrical components 5. Preferably, the lower edge of the air guide 7, i.e., the distal end 7b, through which the air is directed, is positioned at the same height as or below the lowest portion A of the air conditioning assembly 3 and the electrical components 5.

[0141] Furthermore, in this variation, opening 9A of the vehicle lower cover 9 is disposed within a projection area X of the heat absorption and release assembly 2 projected onto the vehicle lower cover 9 along the axial direction of the heat absorption and release assembly 2, so that air exhausted from the heat absorption and release assembly 2 flows out of the front cabin 1 through opening 9A. Preferably, opening 9A of the vehicle lower cover 9 is disposed within a projection area X of the outer contour of the air guide 7, or the air guide 7 and the heat absorption and release assembly 2 as a whole, projected onto the vehicle lower cover 9 along the axial direction of the fan 21, so that air blown out by the fan 21 flows out of the front cabin 1 through opening 9A. Of course, in this variation, a structure may also be employed in which the heat absorption and release assembly 2, electrical components 5, and / or air conditioning assembly 3 are disposed in the vehicle rear space 4, and the suppression structure for the heat absorption and release assembly is used to suppress wind from blowing toward the air conditioning assembly 3 and / or electrical components 5 in the vehicle rear space 4.

[0142] According to the structure of this variant, combined with the advantages of the first to third embodiments, it is possible to further and more effectively prevent the air blown out by the fan 21 from being blown directly to the air-conditioning component 3 and the electrical components 5, and to prevent outdoor rainwater or condensed water in the front cabin 1 and the rear space 4 of the vehicle from being blown to the surrounding electrical components 5 and air-conditioning component 3 through the heat exchanger 20 and the fan 21.

[0143] <Fourth embodiment>

[0144] See also Figure 11 In the fourth embodiment, the heat absorption and release component 2, the electrical components 5, and the air conditioning component 3 are arranged in the vehicle rear space 4. Of course, in the fourth embodiment, the heat absorption and release component 2, the electrical components 5, and the air conditioning component 3 can also be arranged in the front cabin 1. Figure 9 The preferred structure in the variant example 2 of the second embodiment shown (i.e., the air guide member 7 continuously arranged around the fan 21 extends from the outer wall of the first shell 22 to the position of the opening 9A that surrounds the vehicle lower cover 9) is different in the setting of the opening 10A.

[0145] In the fourth embodiment, an opening 10A for discharging the air exhausted from the heat absorption and release component 2 into the vehicle rear space 4 is provided on the vehicle side cover 10, and the air guide 7 continuously arranged around the fan 21 extends from the outer wall of the first shell 22 to a position that surrounds the opening 10A of the vehicle side cover 10 all around, that is, the air guide 7 extends toward the vehicle lower cover 9 and then extends toward the opening 10A of the vehicle side cover 10 and covers the opening 10A all around.

[0146] As a result, all of the air blown out from fan 21 is guided by air guide 7, which extends to and completely surrounds opening 10A of vehicle-side hood 10, and flows out of vehicle rear space 4 through opening 10A. This structure completely prevents air blown out from heat absorption and release module 2 from being blown onto air conditioning module 3 and electrical components 5.

[0147] <Fifth embodiment>

[0148] See also Figure 12 In the fifth embodiment, the heat absorption and release component 2, the electrical components 5, and the air conditioning component 3 are arranged in the vehicle rear space 4. Figure 9 The preferred structure in the variant example 2 of the second embodiment shown (i.e., the air guide member 7 continuously arranged around the fan 21 extends from the outer wall of the first shell 22 to the position of the opening 9A that surrounds the vehicle lower cover 9) is different from the fourth embodiment in that the setting of the opening 11A is different.

[0149] In the fifth embodiment, an opening 11A for discharging the air exhausted from the heat absorption and release component 2 into the rear space 4 of the vehicle is provided on the rear cover 11 of the vehicle, and the air guide member 7 continuously arranged around the fan 21 extends from the outer wall of the first shell 22 to a position that surrounds the opening 11A of the rear cover 11 of the vehicle. That is, the air guide member 7 extends toward the lower cover 9 of the vehicle and then extends toward the opening 11A of the rear cover 11 of the vehicle and covers the opening 11A all around.

[0150] As a result, all of the air blown out from fan 21 is guided by air guide 7, which extends to and completely surrounds opening 11A of rear decklid 11, and flows out of vehicle rear space 4 through opening 11A. This structure completely prevents air blown out from heat absorption and release module 2 from being blown onto air conditioning module 3 and electrical components 5.

[0151] <Sixth embodiment>

[0152] See also Figure 13In the sixth embodiment, the heat absorption and release assembly 2, electrical components 5, and air conditioning unit 3 are arranged in the vehicle rear space 4. The sixth embodiment differs from the preferred structure of Modification 2 of the second embodiment, the fourth embodiment, and the fifth embodiment in that the heat absorption and release assembly 2 is arranged upside down in the vehicle rear space 4. Specifically, the heat exchanger 20 is located closer to the vehicle undercover 9 relative to the first housing 22.

[0153] An opening 11A for the air exhausted from the heat absorption and release component 2 to be discharged into the rear space 4 of the vehicle is set in the rear cover 11 of the vehicle, and the air guide 7 extends from the outer wall of the first shell 22 to a position that surrounds the opening 11A all around, that is, the air guide 7 extends toward the opening 11A of the rear cover 11 of the vehicle and covers the opening 11A all around.

[0154] As a result, all of the air blown out from fan 21 is guided by air guide 7, which extends to and completely surrounds opening 11A of rear decklid 11, and flows out of vehicle rear space 4 through opening 11A. This structure completely prevents air blown out from heat absorption and release module 2 from being blown onto air conditioning module 3 and electrical components 5.

[0155] exist Figure 13 , an opening 11A for discharging the air exhausted from the heat absorption and release component 2 into the rear space 4 of the vehicle is provided on the rear cover plate 11 of the vehicle, but the present embodiment is not limited thereto. It may also be a structure in which the opening 10A for discharging the air exhausted from the heat absorption and release component 2 into the rear space 4 of the vehicle is provided on the side cover plate 10 of the vehicle, and the air guide member 7 extends from the outer wall of the first shell 22 to a position surrounding the opening 10A all around, that is, the air guide member 7 extends toward the opening 10A of the side cover plate 10 of the vehicle and covers the opening 11A all around.

[0156] As a result, all of the air blown out from fan 21 is guided by air guide 7, which extends to and completely surrounds opening 10A of vehicle-side hood 10, and flows out of vehicle rear space 4 through opening 10A. This structure completely prevents air blown out from heat absorption and release module 2 from being blown onto air conditioning module 3 and electrical components 5.

[0157] In addition, it is also possible that an opening 9A for discharging air discharged from the heat absorption and release component 2 into the rear space 4 of the vehicle is provided on the vehicle lower cover 9, and the air guide member 7 extends from the outer wall of the first shell 22 to a position surrounding the opening 9A all around, that is, the air guide member 7 extends toward the opening 9A of the vehicle lower cover 9 and covers the opening 9A all around.

[0158] As a result, all of the air blown out from fan 21 is guided by air guide 7, which extends to and completely surrounds opening 9A of vehicle under-hood 9, and flows out of vehicle rear space 4 through opening 9A. This structure completely prevents air blown out from heat absorption and release module 2 from being blown onto air conditioning module 3 and electrical components 5.

[0159] In the sixth embodiment, since the heat absorption and release component 2, electrical components 5, and air conditioning component 3 are arranged in the vehicle rear space 4, the air inlet for introducing air into the vehicle rear space 4 is set at a position close to the vehicle lower cover 9. By setting the heat absorption and release component 2 upside down, the heat exchanger 20 is brought closer to the air inlet, and a shorter duct guiding air to the heat exchanger 20 can be set, which effectively reduces wind resistance and pressure loss and can improve heat exchange efficiency.

[0160] In the sixth embodiment, it is preferred that the air inlet of the heat exchanger 20 faces the vehicle lower cover 9, thereby further effectively reducing wind resistance and pressure loss and improving heat exchange efficiency.

[0161] The present disclosure is not limited to the above-mentioned specific examples. As long as those skilled in the art make appropriate design changes to the above-mentioned specific examples and possess the characteristics of the present disclosure, they are included in the scope of the present disclosure. The various elements, configurations, conditions, shapes, etc. of the above-mentioned specific examples are not limited to the exemplified contents and can be appropriately changed. As long as the various elements of the above-mentioned specific examples do not cause technical contradictions, they can be appropriately changed and combined.

[0162] In the above embodiments, the structure for simultaneously suppressing air from reaching the electrical components and the air conditioning unit has been described. However, the present disclosure is not limited thereto, and any structure may be used as long as it can suppress air from reaching at least one of the electrical components and the air conditioning unit.

[0163] In a structure capable of suppressing air from reaching the air-conditioning component (without particular emphasis on suppressing air from reaching electrical components), the structure described with "air-conditioning component 3 and electrical components 5" in the above embodiments is described with "air-conditioning component 3 and electrical components 5" instead of "air-conditioning component 3 and electrical components 5".
