Description

Technical Field

[0001] The present invention 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] In the prior art, a heat absorption and release assembly and an air conditioning assembly are arranged in a cabin space of a vehicle, for example, under an engine hood or a motor hood. When the heat absorption and release assembly is horizontally placed in the cabin, for example, the heat absorption and release assembly is located close to the vehicle air conditioning assembly (for example, a compressor, a liquid accumulator, an expansion valve, piping, etc.).

[0003] The air blown out from the heat absorption and release component is likely to be blown directly to the air conditioning component, so it is easy to exchange heat with the blown air on the surface of the air conditioning component, which may reduce the cooling and heating efficiency of the air conditioning component and deteriorate the performance and efficiency of the vehicle thermal management system. In addition, rainwater or condensed water is also easy to be blown to the surrounding electrical parts or air conditioning components through the heat absorption and release component, which may reduce the durability of the electrical parts or air conditioning components such as waterproofing. 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 can also prevent rainwater or condensed water discharged from the heat absorption and release component from blowing to 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 configured with a heat absorption and release component and an air conditioning component for air conditioning in the vehicle cabin in the cabin, and the suppression structure is configured to suppress the air exhausted from the heat absorption and release component from reaching the air conditioning component.

[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 can also prevent rainwater or condensed water discharged from the heat absorption and release component from being blown to the surrounding electrical parts or air conditioning components, thereby improving the durability of electrical parts, etc.

[0007] In a possible embodiment, the suppression structure is an air guide member disposed on the outer peripheral side of the heat absorption and release component.

[0008] According to such a structure, the air guide member 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. It can also prevent rainwater or condensed water discharged from the heat absorption and release component from being blown to the surrounding electrical parts or air conditioning components, thereby improving the durability of electrical parts, etc.

[0009] In a possible embodiment, the suppression structure is as follows: an opening of a lower cover plate of a vehicle is arranged within a projection area of ​​the heat absorption and release component along the axial direction of the heat absorption and release component onto the lower cover plate of the vehicle, so that air exhausted from the heat absorption and release component flows out of the cabin through the opening.

[0010] According to such a structure, by setting the opening of the vehicle lower cover plate within the projection area of ​​the heat absorption and release component along the axial direction of the heat absorption and release component onto the vehicle lower cover plate, 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 cabin through the opening, thereby improving the exhaust efficiency and effectively suppressing the air volume to the air-conditioning component.

[0011] 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.

[0012] 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, it is possible to prevent the air discharged from the heat absorption and release component from being directly blown to the air conditioning component, and it is also possible to prevent rainwater or condensed water discharged from the heat absorption and release component from being blown to surrounding electrical parts or air conditioning components, thereby improving the durability of electrical parts, etc.

[0013] In a possible embodiment, the heat absorption and release component includes a heat exchanger, an air supply device, an upper shell and a lower shell, the heat exchanger is used to perform heat exchange on the air sucked into the cabin, the air after heat exchange through the heat exchanger is blown out through the air supply device, the upper shell is located between the heat exchanger and the air supply device, the upper shell and the lower shell are joined to form a space for accommodating the air supply device, the upper shell includes a through portion that penetrates the upper shell from two opposite ends of the upper shell in the axial direction of the heat absorption and release component, the through portion is used to guide the air that passes through the heat exchanger to the air supply device, and the air blown out by the air supply device passes through the upper shell. The air is blown out from an opening formed between the shell and the lower shell, the air guide is a plate extending from the outer wall of the upper shell along the direction away from the upper 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 upper shell facing the air supply device and the heat exchanger, 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, the proximal end of the air guide is the end of the air guide close to the upper shell, the distal end of the air guide is the end of the air guide away from the upper shell, and the air guide is at least arranged on the side of the upper shell closest to the air-conditioning component.

[0014] 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, the air guide member is at least arranged on the side of the upper shell closest to the air-conditioning component, so that the air guide member can prevent most of the air blown out from the air supply device from directly blowing onto the air-conditioning component, and can also prevent rainwater or condensed water discharged from the air supply device from blowing onto surrounding electrical parts or air-conditioning components, thereby improving the durability of electrical parts, etc.

[0015] In a possible embodiment, the distal end of the air guide member moves away from the air supply device in a radial direction of the air supply device as it moves away from the upper shell in an axial direction of the air supply device.

[0016] 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.

[0017] In a possible embodiment, the lower edge of the air guide member for guiding air to be blown out is located below or at the same height as the lowest part of the air conditioning component.

[0018] 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 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, thereby improving the durability of electrical parts, etc.

[0019] 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.

[0020] According to such a configuration, the amount of air directly blown from the air supply device to the air conditioning unit can be further reduced.

[0021] In a possible embodiment, a plurality of air guide members are intermittently arranged around the air supply device.

[0022] 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.

[0023] In a possible embodiment, the air guiding member is continuously arranged around the air supply device.

[0024] According to such a configuration, the amount of air directly blown from the air supply device to the air conditioning unit can be reduced more effectively.

[0025] 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.

[0026] 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, therefore, 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.

[0027] In a possible embodiment, the opening of the lower cover of the vehicle is arranged in a projection area where the outer contour of the air guide member or the outer contour of the air guide member and the heat absorption and release component are projected as a whole along the axial direction of the air supply device possessed by the heat absorption and release component into the lower cover of the vehicle, so that the air blown by the air supply device flows out of the cabin through the opening.

[0028] According to such a structure, by setting the opening of the vehicle's lower cover plate in the projection area where the outer contour of the air guide member or the outer contour of the air guide member and the heat absorption and release component are projected as a whole along the axial direction of the air supply device onto the vehicle's lower cover plate, 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 exhausted from the air supply device is immediately discharged from the cabin from the opening, thereby improving the exhaust efficiency and effectively suppressing the air volume to the air-conditioning component.

[0029] In a possible embodiment, the air guide extends from the outer wall of the upper shell to the lower cover of the vehicle, and the air guide has at least a portion located between the air conditioning assembly and the opening of the lower cover of the vehicle.

[0030] According to such a structure, the air exhausted from the heat absorption and release component can be effectively guided to the opening position of the vehicle lower cover plate and discharged directly. It can further ensure that the exhausted air is not blown directly to the air conditioning component, which can improve the exhaust efficiency, and can further effectively prevent the rainwater or condensed water discharged from the air supply device from blowing to the surrounding electrical parts or air conditioning components, thereby improving the durability of the electrical parts, etc.

[0031] In a possible embodiment, the air guide extends from the outer wall of the upper shell all the way to a position that all the way surrounds the opening of the vehicle lower cover.

[0032] According to such a structure, all the air discharged from the heat absorption and release component can be effectively guided to the opening position of the vehicle's lower cover and discharged directly without being blown to the air-conditioning component, which can improve the exhaust efficiency and further effectively prevent rainwater or condensed water discharged from the air supply device from blowing to the surrounding electrical parts or air-conditioning components, thereby improving the durability of electrical parts, etc.

[0033] In a possible embodiment, the air conditioning component includes at least a compressor, piping, and an expansion valve.

[0034] According to such a structure, the heat loss of the air conditioning component can be effectively reduced by the suppression structure for the heat absorption and release component, the performance and efficiency of the air conditioning component can be improved, and the durability of electrical parts and the like can be improved.

[0035] In a possible embodiment, the axial direction of the heat absorption and release component is inclined relative to the lower cover plate of the vehicle.

[0036] 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

[0063] Hereinafter, embodiments of the present invention 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 element described in the previous embodiments can be applied to the other parts of the structural element. In the following embodiments, each embodiment can be partially combined with each other even if it is not specifically stated, as long as it does not particularly hinder the combination.

[0064] <First embodiment>

[0065] First, refer to Figures 1 to 7 A first embodiment will be described.

[0066] There is a cabin 1 space under the engine hood or motor hood on the front side of the vehicle, and wind enters the cabin 1 from the outside of the vehicle. The cabin 1 is equipped with a heat absorption and release component 2 and an air conditioning component 3 for air conditioning in the vehicle. The air conditioning component 3 includes at least a compressor, piping, and an expansion valve (all not shown), and some air conditioning components also include a liquid accumulator, etc. In the present invention, as long as it is assembled into a component with the compressor, piping, and expansion valve and used for air conditioning in the vehicle, and the components that affect the air conditioning performance of the air conditioning component 3 through heat exchange with the air are included in the structure of the air conditioning component 3. In addition, various electrical parts are also arranged in the cabin 1.

[0067] 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 the air exhausted from the heat absorption and release module 2 from reaching the air conditioning module 3 .

[0068] The heat absorption and release assembly 2 includes a heat exchanger 20 , a fan 21 (air supply device), an upper shell 22 and a lower shell 23 .

[0069] The heat exchanger 20 is used to perform heat exchange on the air sucked into the nacelle 1, and the air after heat exchange through 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 turbo fan, and may be other air supply devices such as a multi-blade blower.

[0070] The upper shell 22 is located between the heat exchanger 20 and the fan 21. The upper shell 22 and the lower shell 23 are joined to form a space for accommodating the fan 21. The upper shell 22 includes a through portion 24 that penetrates the upper shell 22 from both ends of the upper shell 22 that are opposite in the axial direction of the heat absorption and release component 2. The through portion 24 is used to guide the air passing through the heat exchanger 20 to the fan 21, and the air blown out by the fan 21 is blown out through the opening 25 formed between the upper shell 22 and the lower shell 23.

[0071] See also Figure 2Specifically, the heat exchanger 20 is fixedly connected to the end of the upper shell 22 which is away from the fan 21 in the axial direction. Four upper pillars 221 are respectively provided at the four corners of the lower end surface 22a of the upper shell 22 which has a substantially rectangular outer contour, and four lower pillars 231 are respectively provided at the four corners of the upper end surface 23a of the lower shell 23 which has a substantially rectangular outer contour, and the upper shell 22 and the lower shell 23 are respectively provided at the four corners of the upper end surface 23a of the lower shell 23 which has a substantially rectangular outer contour. The upper shell 22 and the lower shell 23 are assembled into a shell assembly having a substantially rectangular outer contour by, for example, welding the lower ends of the four upper pillars 221 and the upper ends of the four lower pillars 231. Thus, openings 25 are formed on the four side surfaces of the shell assembly by being surrounded by the lower end surface 22a of the upper shell 22, the upper pillars 221, the upper end surface 23a of the lower shell 23, and the lower pillars 231. The fan 21 is accommodated in the internal space of the upper shell 22 and the lower shell 23 which are surrounded by the four openings 25. More specifically, the fan 21 is received in a receiving recess formed on the upper end surface 23a of the lower housing 23, and the motor shaft of the motor 10 disposed below the lower housing 23 passes through a hole provided through the receiving recess and is connected to the fan shaft of the fan 21. Thus, the driving force of the motor 10 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 upper housing 22 and the lower housing 23 has a substantially rectangular outer contour, but the specific structure and shape of the upper housing 22 and the lower 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 upper housing 22 and the lower housing 23 or the housing formed by integrally molding the upper housing 22 and the lower housing 23 may have a substantially cylindrical outer contour.

[0072] In this embodiment, the heat exchanger 20, the upper shell 22, the fan 21, and the lower shell 23 are sequentially arranged from top to bottom along the axial direction of the heat absorption and release component 2. In a preferred embodiment, the heat exchanger 20, the upper shell 22, the fan 21, and the lower shell 23 are coaxially arranged. In this embodiment, the axial direction of the heat absorption and release component 2 is also the axial direction of the fan 21.

[0073] The air guide 7 disposed on the outer peripheral side of the heat absorption and release component 2 is more specifically disposed on the outer peripheral side of the upper shell 22. However, the air guide 7 disposed on the outer peripheral side of the upper shell 22 is only an example, and the air guide 7 can be disposed on the outer peripheral side of the heat absorption and release component 2, for example, it can also be disposed on the outer peripheral side of the heat exchanger 20.

[0074] In the present embodiment, the air guide member 7 is a plate extending from the outer wall of the upper housing 22 in a direction away from the upper housing 22 and toward the fan 21, and the air guide member 7 has a proximal end 7a and a distal end 7b, wherein the proximal end 7a (upper end) of the air guide member 7 is an end of the air guide member 7 close to the upper housing 22, and the distal end 7b (lower end) of the air guide member 7 is an end of the air guide member 7 away from the upper housing 22. More specifically, in the present embodiment, the distal end 7b of the air guide member 7 is away from the fan 21 in the radial direction of the fan 21 as it is away from the upper housing 22 in the axial direction of the fan 21.

[0075] See also Figure 2 , a first distance H1 between the proximal end 7a of the air guide 7 and the heat exchanger 20 is less than a second distance H2 between the lower end surface 22a of the upper shell 22 facing the fan 21 and the heat exchanger 20, that is, the lower end surface 22a of the upper 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 upper shell 22.

[0076] In the present embodiment, the air guide 7 only needs to be provided at least on the side of the upper shell 22 closest to the air conditioning assembly 3. For example, the air guide 7 is provided on the upper shell 22 corresponding to the opening 25 facing the air conditioning assembly 3 among the four openings 25. Alternatively, the air guide 7 is provided on the upper shell 22 corresponding to the opening 25 facing the air conditioning assembly 3 and its two adjacent openings 25 among the four openings 25. When the outer contour of the shell assembly formed by assembling the upper shell 22 and the lower 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 at least on the side of the upper shell 22 closest to the air conditioning assembly 3 means that the air guide 7 is provided within a range of 1 / 4 of the outer contour of the shell assembly corresponding to the air conditioning assembly 3.

[0077] In another possible embodiment, the air guide 7 is arranged around the fan 21, and the air guide 7 is intermittently arranged around the fan 21, for example, four air guides that are not connected to each other and are respectively arranged at four corners corresponding to the four openings 25. In another possible embodiment, the air guide 7 is arranged around the fan 21, and is continuously arranged around the fan 21.

[0078] See also Figure 7In this embodiment, the farthest distance H3 in the horizontal direction between the air guide 7 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 farthest part of the air guide 7 from the outer edge 21a of the air guide 7 facing the fan 21 is the far end 7b of the air guide 7. The closer the distance between the air guide 7 and the fan 21 is, the greater the resistance to the air blown out from the fan 21 and the greater the noise; the farther the distance between the air guide 7 and the fan 21 is, the more space in the cabin is occupied. Therefore, by setting it to 14.4%≤H3≤100%, the air guide 7 can be set at a suitable distance relative to the fan 21, which can significantly reduce the resistance of the air guide 7 relative to the air blown out from the fan 21 and reduce the noise.

[0079] In this embodiment, it is preferred that Figure 2 As shown, the lower edge of the air guide 7 for guiding the air to be blown out, i.e., the distal end 7b of the air guide 7, is located at the same height position compared to the lowest part A of the air-conditioning component 3. More preferably, the lower edge of the air guide 7 for guiding the air to be blown out, i.e., the distal end 7b of the air guide 7, is located below the lowest part A of the air-conditioning component 3. However, the lower edge of the air guide 7 for guiding the air to be blown out does not necessarily have to be located at the same height position or below the lowest part A of the air-conditioning component 3. It is also possible that 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 component 3.

[0080] 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, 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 imaginary extension surface of the air guide 7 does not contact the air conditioning unit 3, thereby preventing the air blown out from the fan 21 from being directly blown to the air conditioning unit 3. 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 plate 9 of the vehicle, for example, in Figure 4 In 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 surface shape to the vehicle lower cover 9. Since the extension direction of the imaginary extension surface is roughly consistent with the direction in which the air is blown out from the air guide 7, the imaginary extension surface does not contact the air conditioning unit 3, so even if the lower edge of the air guide 7 that guides the air to be blown out, that is, the distal end 7b, is located above the lowest part A of the air conditioning unit 3, the air blown out from the fan 21 can be prevented from being blown directly to the air conditioning unit 3.

[0081] When the heat absorption and release component 2 is working, air is introduced into the heat exchanger 20 from the outside of the vehicle through the air duct. All the air that has undergone heat exchange in the heat exchanger 20 is guided to the fan 21 through the through-hole 24, and is blown out radially by the fan 21 and flows out from the four openings 25. The outflowing air is guided by the air guide 7 and flows in a direction that will not be blown directly to the air conditioning component 3, and finally flows out of the cabin 1 through the opening provided in the vehicle lower cover plate constituting the bottom surface of the cabin 1. In addition, since in the preferred mode of this embodiment, the distal end 7b of the air guide 7 is located at the same height position as the lowest part A of the air conditioning component 3, it is possible to more effectively prevent the air blown out by the fan 21 from being blown directly to the air conditioning component 3, and it is also possible to prevent outdoor rainwater or condensed water in the cabin 1 from being blown to the surrounding electrical parts and the air conditioning component 3 through the heat exchanger 20 and the fan 21.

[0082] Below, refer to Figures 4 to 6 , structures 1 to 3 of the air guide member 7 continuously arranged around the fan 21 are described. Figures 4 to 6 In the structure, the air guide member 7 is a skirt structure formed by a plate and surrounding the fan 21.

[0083] (Structure 1 of air guide)

[0084] See also Figure 4 The air guide member 7 of the structure 1 forms a conical surface structure that surrounds the fan 21 and is continuously arranged on the outer peripheral side of the upper housing 22. Specifically, the air guide member 7 corresponding to each of the four side surfaces of the upper housing 22 is a flat plate structure, and the distal end 7b of the air guide member 7 on each side is away from the fan 21 in the radial direction of the fan 21 as it moves away from the upper housing 22 in the axial direction of the fan 21. The four flat plates of the air guide member 7 corresponding to the four side surfaces are joined to form a square conical surface structure.

[0085] (Structure 2 of air guide)

[0086] See also Figure 5 The air guide 7 of structure 2 is composed of a conical surface 71 connected to the upper shell 22, a curved surface 72 provided continuously with the conical surface 71, and a prism portion 73 provided continuously with the curved surface 72 from top to bottom. The conical surface 71 has the same structure as the air guide 1 of structure 1. More specifically, the prism portion 73 is formed into a square prism structure, and the curved surface 72 is a structure in which the conical surface 71 and the prism portion 73 are connected by a curved surface.

[0087] (Structure 3 of air guide)

[0088] 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 upper shell 22 and the lower prism portion 75 with a rounded corner.

[0089] The skirt structures of the structures 1 to 3 of the air guide member can smoothly guide the radial wind blown out from the fan 21 to the opening of the vehicle under cover.

[0090] The above is a description of a specific structural example of the air guide member 7 of the first embodiment. The air guide member 7 of the first embodiment is a plate extending from the outer wall of the upper housing 22 in a direction away from the upper housing 22 and approaching the fan 21, and the distal end 7b of the air guide member 7 is away from the fan 21 in the radial direction of the fan 21 as it is away from the upper housing 22 in the axial direction of the fan 21, but the air guide member 7 is not limited to this. The air guide member 7 can be 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. For example, the air guide member 7 can also be a structure in which the distal end 7b of the air guide member 7 is away from the upper 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 member 7 does not have to be a plate member. For example, the air guide member 7 can also be an air guide component formed by assembling multiple parts.

[0091] <Second embodiment>

[0092] Below, refer to Fig. 8A , the second embodiment is described, and the difference between the second embodiment and the first embodiment is mainly described. The same symbols are marked for the same contents as the first embodiment, and repeated description is omitted.

[0093] The heat absorption and release component suppression structure of the second embodiment is a structure in which the opening 9A of the vehicle lower cover 9 is arranged within a projection area X of the heat absorption and release component 2 projected onto the vehicle lower cover 9 along the axial direction of the heat absorption and release component 2, so that the air exhausted from the heat absorption and release component 2 flows out of the cabin 1 through the opening 9A. The opening 9A being arranged within the projection area X also includes a case where the opening 9A substantially overlaps with the projection area X.

[0094] Specifically, the opening 9A of the vehicle lower cover 9 is arranged in a projection area X where the heat absorption and release component 2 including the heat exchanger 20, the fan 21, the upper shell 22, and the lower shell 23 are projected along the axial direction of the heat absorption and release component 2 onto the vehicle lower cover 9. In the present embodiment, the axial direction of the fan 21 (the axial direction of the heat absorption and release component 2) is substantially perpendicular to the vehicle lower cover 9. Preferably, the opening 9A of the vehicle lower cover 9 is arranged in a projection area X where the fan 21 is projected along the axial direction of the fan 21 onto the vehicle lower cover 9. By arranging the opening 9A in the projection area X, the distance between the heat absorption and release component 2 and the opening 9A can be shortened, the wind exhausted from the fan 21 can be immediately discharged from the opening 9A, the exhaust path of the heat absorption and release component can be shortened, the exhaust efficiency can be improved, and the amount of wind directly blown to the air conditioning component 3 can be effectively suppressed.

[0095] (Variation 1 of the Second Embodiment)

[0096] Next, refer to Figure 8B Modification 1 of the second embodiment will be described.

[0097] The difference between variant example 1 of the second embodiment and the second embodiment is that, in variant example 1 of the second embodiment, the air guide member 7 arranged around the fan 21 of the first embodiment is provided, and the opening 9A of the vehicle lower cover 9 is provided in a projection area X of the vehicle lower cover 9 where the outer contour of the air guide member 7 or the outer contour of the air guide member 7 and the heat absorption and release component 2 are projected as a whole along the axial direction of the fan 21, so that the air blown by the fan 21 flows out of the cabin 1 through the opening 9A.

[0098] The so-called outer contour of the air guide member 7 is projected onto the projection area X of the vehicle lower cover 9 along the axial direction of the fan 21. When the air guide member 7 is continuously arranged around the fan 21, the continuous outer edge of the air guide member 7 is projected onto the vehicle lower cover 9 along the axial direction of the fan 21 to obtain the projection area X. 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 9 along the axial direction of the fan 21 to obtain the projection area X.

[0099] See also Figure 8B The projection area X of the outer contour of the air guide 7 and the heat absorption and release component 2 as a whole projected along the axial direction of the fan 21 onto the vehicle lower cover 9 is the projection area X, which is the maximum range obtained by projecting the outer contour of the air guide 7 and the heat absorption and release component 2 along the axial direction of the fan 21 onto the vehicle lower cover 9. In addition, this structure is also applicable to the structure in which the air guide 7 is not arranged around the fan 21, such as the air guide 7 is only arranged on the side of the upper shell 22 closest to the air conditioning component 3.

[0100] In addition, in this modification 1, the axial direction of the fan 21 (the axial direction of the heat absorption and release component 2) is inclined relative to the vehicle lower cover 9, thereby increasing the range of the projection area X and improving the design flexibility of the opening 9A. However, in this modification 1, it is not necessary for the axial direction of the fan 21 to be inclined relative to the vehicle lower cover 9, and the axial direction of the fan 21 can also be perpendicular to the vehicle lower cover 9. In addition, the structure in which the axial direction of the fan 21 is inclined relative to the vehicle lower cover 9 can also be applied to the first embodiment and the third embodiment described later.

[0101] 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 member 7.

[0102] (Variation 2 of the Second Embodiment)

[0103] Next, refer to Fig. 9 Modification 2 of the second embodiment is 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 upper shell 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 opening 9A of the vehicle lower cover 9, preferably as shown in FIG. Fig. 9 As shown, the air guide 7 continuously arranged around the fan 21 extends from the outer wall of the upper housing 22 all the way to a position that surrounds the opening 9A of the vehicle lower cover 9 all the way. That is, all the air blown out from the fan 21 is guided by the air guide 7 that extends to the vehicle lower cover 9 and surrounds the opening 9A of the vehicle lower cover 9 all the way, and all flows out of the cabin 1 through the opening 9A. With such a structure, it is possible to completely prevent the air blown out from the heat absorption and release assembly 2 from being blown to the air conditioning assembly 3.

[0104] However, the structure in which the air guide member 7 extends from the outer wall of the upper shell 22 to the vehicle lower cover 9 and the air guide member 7 has at least a portion located between the air conditioning component 3 and the opening 9A of the vehicle lower cover 9 is not only applicable to the air guide member 7 arranged around the fan 21. In the structure in which the air guide member 7 is not arranged around the fan 21, such as when the air guide member 7 is only arranged on the side of the upper shell 22 closest to the air conditioning component 3, as long as the air guide member 7 extends from the outer wall of the upper shell 22 to the vehicle lower cover 9 and the air guide member 7 separates the air conditioning component 3 and the opening 9A of the vehicle lower cover 9 (that is, the air guide member 7 has at least a portion located between the air conditioning component 3 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.

[0105] <Third Embodiment>

[0106] Next, refer to Fig.10 The third embodiment will be described, and the differences between the third embodiment and the first embodiment will be mainly described. The same reference numerals are used for the same contents as those of the first embodiment, and duplicate description will be omitted.

[0107] The third embodiment is different 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 .

[0108] More specifically, in the third embodiment, see Fig.10The suppression structure is a structure in which the uppermost edge (in this embodiment, the lower end surface 22a of the upper shell 22) of the opening 25 (i.e., the air outlet) formed by the lower end surface 22a of the upper shell 22, the upper column 221, the upper end surface 23a of the lower shell 23, and the lower column 231 is located at the same height position as the lowermost part A of the air conditioning component 3. More preferably, the opening 25 is located below the lowermost part A of the air conditioning component 3. The uppermost edge of the air outlet of the heat absorption and release component 2 refers to the uppermost edge of the outlet for the air discharged from the heat absorption and release component 2 to flow out of the heat absorption and release component 2. The opening 25 formed by the lower end surface 22a of the upper shell 22, the upper column 221, the upper end surface 23a of the lower shell 23, and the lower column 231 is only a specific example of the air outlet.

[0109] In the third embodiment, there is no air guide member, 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, 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.

[0110] (Variation of the Third Embodiment)

[0111] The modified example of the third embodiment is a structure combining the first embodiment and the second embodiment in the third embodiment. Specifically, in this modified example, an air guide 7 is provided, and the uppermost edge of the air outlet of the heat absorption and release component 2 is located below or at the same height position as the lowermost part A of the air conditioning component 3. Preferably, the lower edge of the air guide 7 for guiding the air to be blown out, i.e., the distal end 7b, is located at the same height position or below the lowermost part A of the air conditioning component 3.

[0112] And in this modified example, the opening 9A of the vehicle lower cover 9 is arranged in the projection area X of the heat absorption and release component 2 projected onto the vehicle lower cover 9 along the axial direction of the heat absorption and release component 2, so that the air discharged from the heat absorption and release component 2 flows out of the cabin 1 through the opening 9A. Preferably, the opening 9A of the vehicle lower cover 9 is arranged in the projection area X of the outer contour of the air guide 7 or the outer contour of the air guide 7 and the heat absorption and release component 2 as a whole projected onto the vehicle lower cover 9 along the axial direction of the fan 21, so that the air blown by the fan 21 flows out of the cabin 1 through the opening 9A.

[0113] According to the structure of this variant example, combined with the advantages of the first to third embodiments, it is possible to further more effectively prevent the air blown out by the fan 21 from being blown directly to the air-conditioning component 3, and to prevent outdoor rainwater or condensed water in the cabin 1 from being blown to the surrounding electrical parts and air-conditioning components 3 through the heat exchanger 20 and the fan 21.

[0114] The present invention is not limited to the above-mentioned specific examples. As long as the above-mentioned specific examples are appropriately designed and modified by those skilled in the art, they are included in the scope of the present invention. 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, the combination can be appropriately changed.
