Description

Technical Field

[0001] The utility model relates to a motorhome air conditioner, in particular to an adaptive driving and parking compatible motorhome air conditioner air duct system, which improves a condensing air duct system in a heat exchange system to avoid negative effects of airflow on the condensing air duct system when the motorhome is traveling at high speed. Background Art

[0002] The roof-mounted RV air conditioner includes a panel assembly installed on the inside of the roof and an air conditioner outside the roof. The air conditioner outside usually includes an evaporation system and a condensation system, wherein the condensation system includes a condensation heat exchanger, a condensation fan, and an air inlet and an air outlet.

[0003] Due to the limitations of the structure and arrangement of the condensing heat exchanger and condensing fan inside the outdoor unit of the RV air conditioner, some outdoor units of the RV air conditioner are designed to have side air outlet and rear air intake, or rear air intake and top air outlet. For example, the utility model patent with the authorization announcement number CN207859890U discloses a roof-mounted air conditioner, which has an air inlet on the shell and on the side wall of the external circulation installation area, and an exhaust port on the top of the shell. Such air flow directions are inconsistent with the air flow directions around the outdoor unit of the air conditioner when the RV is driving. When the RV is driving at high speed, the inlet and outlet air are affected by the natural convection of the air. The faster the speed, the worse the heat exchange effect. Even at high speed, the outdoor unit of the air conditioner cannot continue to operate normally and can only be used as a parking air conditioner but not as a driving air conditioner.

DETAILED DESCRIPTION

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0044] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. "First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present utility model.

[0045] like Figures 3 to 7 The roof-mounted RV air conditioner outdoor unit 200 provided in this embodiment includes a housing 10, and an evaporation system 210 and a condensation system 220 installed and arranged inside the housing 10. The condensation system 220 includes a condensation heat exchanger 20 and a condensation fan assembly 30.

[0046] like Figure 1 and Figure 2The figure shows the shape and orientation of the roof-mounted RV air conditioner outdoor unit 200 when it is installed on the outside of the roof of the RV 300. The front of the shell 10 faces the front direction of the RV 300, that is, the forward direction v of the driving, and the two sides of the shell 10 face the side directions of the RV 300.

[0047] The adaptive parking and driving compatible RV air conditioning duct system 100 provided in this embodiment includes a housing 10 and a condensing heat exchanger 20 and a condensing fan assembly 30 arranged in the housing 10. As mentioned above, the housing 10 is used to be installed on the outer side of the roof of the RV 300 with the front facing the driving direction v of the RV 300.

[0048] like Figure 1 and Figure 5 As shown, a first air grille 11 is provided at the side of the housing 10, and a second air grille 12 is provided at the rear of the housing 10. The condensing heat exchanger 20 divides the internal space of the housing 10 into a first space 13 near the front and a second space 14 near the rear, the first space 13 is connected to the first air grille 11, and the second space 14 is connected to the second air grille 12. The condensing fan assembly 30 is arranged in the second space 14 to form a negative pressure at the rear of the housing 10.

[0049] like Figure 5 and Figure 6 , combined with Figure 1 and Figure 2 As shown, when the condensing fan assembly 30 is started, an air pressure difference is generated in the internal space of the shell 10 and near the first wind grille 11 and the second wind grille 12, so that air is taken in from the first wind grille 11 on the side of the shell 10 and discharged from the second wind grille 12 at the rear of the shell 10, so that the air flow direction is consistent with the natural air flow direction when the RV 300 is driving.

[0050] Specifically, the condensing fan assembly 30 generates a local vortex at the rear of the housing 10, thereby generating negative pressure. When parking, the two sides of the exterior of the housing 10 and the interior of the housing 10 are positive pressure relative to the rear of the housing 10, so that the airflow passes through the first wind grid 11, the first space 13, the condensing heat exchanger 20 to the second space 14 in sequence, and the air is discharged from the second wind grid 12. When driving, the natural air flows from the front of the housing 10 through the two sides to the rear, and a negative pressure is naturally formed at the rear, which is then superimposed with the negative pressure formed by the aforementioned condensing fan assembly 30 at the rear of the housing 10. The air flow direction generated by the adaptive parking and driving compatible RV air conditioning duct system 100 is consistent with the natural air flow direction of driving, and the effects are superimposed and enhanced to generate convection gain.

[0051] It can be seen that the adaptive driving and parking compatible RV air conditioning duct system 100 provided by the utility model realizes that the air flow direction is adaptive to the natural air flow direction during driving, and can overcome the problem in the prior art that the air flow direction of the RV air conditioning external unit is inconsistent with the natural air flow direction during driving, or even opposite to the natural air flow direction during driving, which causes low heat exchange efficiency when the vehicle is driving at high speed, or even stops running, and can only be used as a parking air conditioner, thereby realizing the compatibility of driving air conditioning and parking air conditioning. Since the air flow direction of the air conditioning external unit is consistent with the natural air flow direction during driving, when the vehicle is driving, the natural convection of the air is more conducive to improving the heat exchange efficiency of the condensing heat exchanger, and the heat exchange effect is better.

[0052] like Figure 5 and Figure 7 As shown, further, the condensing fan assembly 30 is an axial flow fan assembly, including a support plate 31, a motor 32 and a fan blade 33, the fan blade 33 is connected to the motor 32, the motor 32 is fixed to the support plate 31, and the motor 32 is used to drive the fan blade 33 to rotate. The support plate 31 is vertically installed in the second space 14 to vertically arrange the fan blade 33 in the second space 14, and the air supply direction of the fan blade 33 is toward the second wind grid 12, so as to generate negative pressure in the rear space of the fan blade 33, that is, the rear of the housing 10, and the air flow is sent out from the second wind grid 12.

[0053] like Figure 5 and Figure 7 As shown, the condensing heat exchanger 20 is U-shaped to enclose the second space 14, the opening of the U-shape faces the second wind grid 14, the condensing fan assembly 30 is arranged inside the U-shape, and the fan blades 33 are close to the opening of the U-shape. The lower part of the condensing heat exchanger 20 is installed at the bottom of the shell 10, the upper part of the condensing heat exchanger 20 is provided with a condensing cover plate 21, and the opening of the U-shape is provided with an air induction ring 22. The U-shaped condensing heat exchanger 20, the bottom of the shell 10, the condensing cover plate 21, and the air induction ring 22 define the boundary of the second space 14. The air induction ring 22 and the fan blades 33 are almost in the same vertical plane.

[0054] The U-shaped condensing heat exchanger 20 is set so that the condensing heat exchanger 20 is not restricted in the width direction, the windward area of ​​the condensing heat exchanger 20 is increased, the heat exchange area is increased, and the heat exchange performance of the condensing heat exchanger 20 is improved. It should be noted that in other embodiments, the condensing fan assembly 30 may not use an axial flow fan, for example, a vortex fan is used, but it is necessary to achieve the generation of negative pressure at the rear of the housing 10.

[0055] However, the present embodiment preferably adopts an axial flow fan so that the condensing fan assembly 30 can be wrapped in the rear part of the U-shaped condensing heat exchanger 20. The space between the U-shaped condensing heat exchanger 20 and the condensing fan assembly 30 is the second space 14, which is the heat exchange space. Since the U-shaped condensing heat exchanger 20 can form a larger distance between the condensing fan assembly 30, the heat exchange space is more sufficient, so that the airflow field through the condensing heat exchanger 20 is more uniform, and the heat exchange efficiency is further improved.

[0056] like Figure 3 and Figure 7 As shown, the housing 10 includes an upper housing 10a and a lower housing 10b, a first upper air grille 11a is provided on the side of the upper housing 10a, a second upper air grille 12a is provided on the rear of the upper housing 10a, a first lower air grille 11b is provided on the side of the lower housing 10b, and a second lower air grille 12b is provided on the rear of the lower housing 10b. The upper housing 10a and the lower housing 10b are combined to form the housing 10, the first upper air grille 11a and the first lower air grille 11b form the first air grille 11, and the second upper air grille 12a and the second lower air grille 12b form the second air grille 12.

[0057] The use of an upper and lower shell structure can facilitate the assembly of the entire roof-mounted RV air-conditioning outdoor unit 200, and wind grilles are provided on the upper and lower shells, so that the first wind grille and the first space, and the second wind grille and the second space can be fully connected in the vertical space, respectively, so that the air flow is smoother and more uniform, while fully exchanging heat with the condensing heat exchanger 20.

[0058] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0059] The above is an introduction to the adaptive parking and driving compatible RV air conditioning duct system provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas.
