[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0039] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0040] Combination Figure 1-7 As shown, the present invention provides a condenser core assembly 9, comprising: two opposite headers 1, a plurality of harmonica tubes 2, an inlet pressure plate 3 and an outlet pressure plate 4, wherein a connecting cavity 101 is arranged in the header 1; the plurality of harmonica tubes 2 are arranged in sequence, and the two ends of each harmonica tube 2 are respectively connected to the two headers 1, and are respectively connected to the two connecting cavities 101; the inlet pressure plate 3 is connected to one end of one of the headers 1, for the refrigerant to flow into one of the headers 1; the outlet pressure plate 4 is connected to the other end of one of the headers 1, for the refrigerant to flow out of one of the headers 1; wherein the harmonica tubes 2 are inclined to a horizontal plane perpendicular to the headers 1.

[0041] In the embodiment of the present invention, the refrigerant enters the connecting cavity 101 of the manifold 1 from the inlet pressure plate 3, flows into the harmonica tube 2 through the connecting cavity 101, and flows into the relative manifold 1 through the harmonica tube 2, and then flows into the harmonica tube 2 through the manifold 1, and so on. The cycle is repeated, and heat is exchanged with the harmonica tube 2, and the harmonica tube 2 exchanges heat with the air, so that the high-temperature gaseous refrigerant is gradually cooled down, and finally the refrigerant flows out of the manifold 1 from the outlet pressure plate 4, and is inclined in a horizontal plane perpendicular to the manifold 1 through the harmonica tube 2. When the inner diameter of the manifold 1 remains unchanged, the width of the harmonica tube 2 is increased, thereby increasing the heat dissipation area of ​​the outer side of the harmonica tube 2, and then increasing the heat dissipation of the condenser, so that the air-conditioning performance can meet the comfort requirements of the cab.

[0042] Specifically, the heat dissipation Q of the condenser is an important indicator of the condenser. According to the formula Q=K*F*Δt, where F is the heat dissipation area and K is the heat transfer coefficient, when the temperature difference Δt is constant, the heat dissipation Q is proportional to the heat dissipation area F.

[0043] In some embodiments, the inclined angle between the harmonica pipe 2 and the horizontal plane perpendicular to the collecting pipe 1 is θ, 0≤θ≤45°.

[0044] In this embodiment, the inclination angle between the harmonica tube 2 and the horizontal plane perpendicular to the collecting tube 1 ranges from 0 to 45°, so that more harmonica tubes 2 can be arranged on the collecting tube 1 while the harmonica tubes 2 are inclined, thereby enhancing the heat dissipation effect of the condenser core assembly 9.

[0045] In some embodiments, the inclined angle θ between the harmonica pipe 2 and the horizontal plane perpendicular to the collecting pipe 1 is 30°.

[0046] In this embodiment, the inclination angle between the harmonica tube 2 and the horizontal plane perpendicular to the collecting pipe 1 is set to 30°, so that more harmonica tubes 2 can be arranged, and the inclination angle of 30° is convenient for production and large-scale processing.

[0047] In some embodiments, a plurality of fins 5 are disposed between two adjacent harmonica tubes 2 , and the fins 5 are used for heat exchange with air.

[0048] In this embodiment, the fins 5 are used to perform heat exchange with the air, further improving the heat dissipation effect of the condenser core assembly 9.

[0049] In some embodiments, a plurality of fins 5 are connected end to end in sequence.

[0050] In this embodiment, a plurality of fins 5 are connected end to end in sequence, and more fins 5 can be arranged between two adjacent harmonica tubes 2. The contact area between the fins 5 and the air is increased. The larger contact area helps to promote the conduction and dissipation of heat, thereby improving the heat dissipation effect of the condenser core assembly 9.

[0051] Combination Figure 3 As shown, when the plane of the harmonica tube 2 is perpendicular to the manifold 1, that is, when the harmonica tube 2 is located in a horizontal plane perpendicular to the manifold 1, the width of the harmonica tube 2 is L1, the width of the fin 5 is W1, and the inclined angle between the harmonica tube 2 and the horizontal plane perpendicular to the manifold 1 is θ (0≤θ≤45°). At this time, the width of the harmonica tube 2 is L2, L2=L1 / cosθ, and the width of the fin 5 is W2, W2=W1 / cosθ; when the manifold 1 remains unchanged, the total heat dissipation area F of the condenser increases to F / cosθ, and the condenser cooling capacity increases to approximately Q / cosθ. In a specific embodiment, when θ=30°, the condenser cooling capacity increases by approximately 15%.

[0052] The present invention also provides a condenser, comprising: an integrated cover 6, a motor 7, a fan 8 and the condenser core assembly 9 as described above, wherein an opening 601 is provided at one end of the integrated cover 6, the motor 7 is connected to the integrated cover 6, the fan 8 is connected to the motor 7 and the fan 8 is arranged toward the opening 601, and the condenser core assembly 9 is connected to the other end of the integrated cover 6.

[0053] In the embodiment of the present invention, the condenser core assembly 9 is connected to the other end of the integrated cover 6, and is inclined through the harmonica tube 2 and the horizontal plane perpendicular to the collecting pipe 1. When the inner diameter of the collecting pipe 1 remains unchanged, the width of the harmonica tube 2 is increased, thereby increasing the heat dissipation area of ​​the outer side of the harmonica tube 2, thereby increasing the heat dissipation of the condenser, so that the air-conditioning performance can meet the comfort requirements of the cab.

[0054] In some embodiments, the inclined angle between the horizontal plane where the opening 601 is located and the horizontal plane where the other end of the integrated cover 6 is located is equal to the inclined angle between the horizontal planes perpendicular to the harmonica pipe 2 and the manifold 1 .

[0055] In this embodiment, the wind direction blown by the fan 8 of the condenser is the same as the air inlet direction of the harmonica tube 2, which ensures the smoothness of air flow. The air can flow more effectively between the fan 8 and the harmonica tube 2, thereby improving the heat exchange efficiency between the harmonica tube 2 and the air.

[0056] In some embodiments, the condenser also includes: a drying bottle 10 and a pressure switch 11, the drying bottle 10 is connected to the integrated cover 6 and connected to the connecting cavity 101 of one of the collecting pipes 1; the pressure switch 11 is connected to the drying bottle 10 and is used to detect the pressure value in the drying bottle 10, and the condenser is closed when the pressure value reaches a preset pressure.

[0057] In this embodiment, the drying bottle 10 is connected to the integrated cover 6 and connected to the connecting cavity 101 of one of the manifolds 1, which is used to remove moisture from the refrigerant flowing into the manifold 1. The drying bottle 10 is connected to the manifold 1 so that the pressure in the drying bottle 10 is equal to the pressure in the manifold 1. The pressure in the manifold 1 can be determined by detecting the pressure value in the drying bottle 10 through the pressure switch 11. When the pressure value reaches the preset pressure, the condenser is closed to protect the manifold 1 to increase the service life of the manifold 1 and the harmonica tube 2, wherein the preset pressure is set according to the actual application scenario. Specifically, when the pressure is higher than 2.85±0.2Mpa or lower than 0.196±0.02Mpa, the air-conditioning compressor is disconnected and the condenser is shut down, thereby protecting the air-conditioning system.

[0058] In some embodiments, the condenser is used to be installed on a target installation object in a car, and the condenser also includes: a bracket assembly 12, the bracket assembly 12 includes a first bracket 121 and a second bracket 122, the first bracket 121 and the second bracket 122 are respectively connected to both sides of the integrated cover 6, and are respectively connected to the target installation object.

[0059] In this embodiment, the bracket assembly 12 is used to fix the condenser on the target installation object in the car to prevent the condenser from detaching. The first bracket 121 and the second bracket 122 are respectively connected to both sides of the integrated cover 6 to make the condenser more stable.

[0060] The present invention also provides a car, comprising a car body (not shown) and the condenser as described above, wherein the condenser is connected to the car body.

[0061] In the embodiment of the present invention, in order to ensure the height of the parts from the ground and the passability of the whole vehicle, the height of the condenser on the car is strictly controlled. Under the condition of limited boundaries, the condenser as described above is arranged on the car body to meet the comfort requirements of the whole vehicle. The harmonica tube 2 is inclined in a horizontal plane perpendicular to the collecting pipe 1, and the width of the harmonica tube 2 is increased while the inner diameter of the collecting pipe 1 remains unchanged, thereby increasing the heat dissipation area of ​​the outer side of the harmonica tube 2, thereby increasing the heat dissipation of the condenser, so that the air-conditioning performance can meet the comfort requirements of the cab.

[0062] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
