[0050] This disclosure provides a vehicle air conditioner that can be used in vehicles such as trucks. However, it should be understood that the vehicle air conditioner of this disclosure is not limited to trucks or other vehicles, and can be applied to other suitable situations without departing from the spirit and purpose of this disclosure.

[0051] Furthermore, the following description may not delve into the basic principles of air conditioning, or the constructions known to those skilled in the art, particularly in the context of vehicle air conditioning, but will instead focus on describing the improvements of this disclosure.

[0052] Refer to each Figures 1-3 ,in Figure 1 This is a perspective view of the vehicle air conditioner as seen from above, based on the present disclosure. Figure 2 This is a perspective view of the vehicle air conditioner as seen from below, based on the present disclosure. Figure 3 This is an exploded view of an in-vehicle air conditioner according to this disclosure. This disclosure relates to an in-vehicle air conditioner 1000, which includes a housing 40 and a chassis 41 forming a receiving cavity for accommodating the main components of the in-vehicle air conditioner, described later. The in-vehicle air conditioner 1000 also includes a condenser unit 2 and an evaporator unit 1 as basic components of the air conditioner. The condenser unit 2 is disposed within the receiving cavity and includes a condenser housing 22 and a condenser 20. The evaporator unit 1 is disposed within the receiving cavity and includes an evaporator housing 12 and an evaporator 10. The principles of the condenser and evaporator will not be elaborated further in this disclosure.

[0053] In the embodiments of this disclosure, the definitions of direction and orientation are as follows: the first direction is along... Figure 1 The direction of the center + X is also known as the windward direction (the direction in which the wind blows towards the vehicle when it is moving). The second direction is along. Figure 1 In the +Y direction, the third direction is along Figure 1 The +Z direction. However, when it comes to forward / backward, left / right, and up / down directions, it is oriented towards... Figure 1 The location of the vehicle's air conditioning unit is described, that is... Figure 1 The left-right and up-down directions mentioned above are the same as the left-right and up-down directions in the subsequent description. Figure 1 In the diagram, the direction inside the paper is the backward direction, and the direction outside the paper is the forward direction.

[0054] like Figure 3The condenser unit 2 is located in the front portion of the vehicle air conditioner 1000, and the evaporator unit 1 is located in the rear portion of the vehicle air conditioner 1000. That is, the evaporator unit 1 is located behind the condenser unit 2. This arrangement better isolates the evaporator unit from the external environment, providing further protection for the evaporator unit via the condenser unit. Furthermore, this arrangement, combined with the condenser air inlet, allows ambient air to be drawn into the condenser's flow path by the airflow generated by the vehicle's speed, increasing airflow and the resulting heat exchange, improving operating efficiency and saving energy consumption, which will be described further later.

[0055] Figure 4 The top view of the vehicle air conditioner 1000 disclosed herein shows the positional relationship between the evaporator unit 1 and the condenser unit 2 more clearly. Furthermore, in embodiments of this disclosure, the basic components of the evaporator unit 1 are located in the receiving space formed by the evaporator housing 12 and the chassis 41, and the basic components of the condenser unit 2 are located in the receiving space formed by the condenser housing 22 and the chassis 41.

[0056] Reference Figure 1 and Figure 5 ,in Figure 5 A top view of the vehicle air conditioner 1000 according to the present disclosure is shown with the outer casing 40 removed. In embodiments of the present disclosure, the evaporator unit 1 extends into the recess 24 formed by the condenser unit 2. More specifically, the front portion of the evaporator unit 1 extends into the recess 24 formed by the condenser unit 2, thereby forming a similar interlocking or nested structure. This arrangement allows for a significant reduction in the overall size (i.e., width) of the vehicle air conditioner 1000 in the second direction, resulting in a more compact structure. Furthermore, as previously mentioned, the recess 24 of the condenser unit 2 can form a barrier for the evaporator unit 1.

[0057] In addition, a partition can be installed between the evaporator unit 1 and the condenser unit 2 to further separate them, thereby avoiding possible adverse effects of the external environment and the condenser unit on the evaporator unit.

[0058] Continue to refer to Figure 5 The projection of the evaporator unit 1 along the first direction falls within the range of the projection of the condenser unit 2 along the first direction. That is, the size of the evaporator unit 1 in the first direction is smaller than the size of the condenser unit 2 in the second direction. Therefore, in the windward direction, the evaporator unit 1 will be completely located behind and shielded by the condenser unit 2, thus providing protection for the evaporator unit 1.

[0059] Continue to refer to Figure 5The projection of the condenser unit 2 along the second direction overlaps with the projection of the evaporator unit 1 along the second direction. This allows for a reduction in the overall width of the vehicle air conditioner 1000.

[0060] Reference Figure 6 , Figure 6 This is a top view of the vehicle air conditioner 1000 according to the present disclosure, wherein the outer casing, evaporator housing 12, and condenser housing 22 of the vehicle air conditioner 1000 have been removed. Both the evaporator 10 and the condenser 20 are formed in a generally U-shaped structure, and the evaporator 10 is partially located within the space enclosed by the U-shaped structure of the condenser 20. It should be understood that the U-shaped structure in this disclosure is only a general description and does not exclude some other detailed features, such as the condenser 20 further including a fourth segment 204 as described later. The recess of the condenser 2, as previously described, is located within the recess formed by the generally U-shaped structure. The arrangement of the U-shaped structure of the condenser allows the condenser to extend along the outer periphery of the vehicle air conditioner and makes the resulting accommodating space more regular, facilitating a more compact arrangement. The smaller U-shaped structure of the evaporator forms a similar nested arrangement with the condenser, also making the overall arrangement more compact.

[0061] Continue to refer to Figure 6 The generally U-shaped condenser 20 includes a first segment 200 extending along a second direction and a second segment 201 and a third segment 202 extending along a first direction perpendicular to the first segment 200. The generally U-shaped evaporator 10 includes a first segment 100 extending along a second direction and a second segment 101 and a third segment 102 extending along a first direction perpendicular to the first segment 100. The first segment 100 of the evaporator 10 is located within the space enclosed by the U-shaped structure of the condenser 20, and the second segment 101 and the third segment 102 of the evaporator 10 partially extend into the space enclosed by the U-shaped structure of the condenser 20.

[0062] In embodiments of this disclosure, the first section 200 of the condenser 20 extends generally along the front side of the vehicle air conditioner 1000, and the second section 201 and the third section 202 of the condenser 20 extend generally along the left and right sides of the vehicle air conditioner 1000. The first section 100 of the evaporator 10 is generally located in the middle portion of the vehicle air conditioner 1000.

[0063] Further reference Figure 6 In the first direction, the first section 100 of the evaporator 10 is shorter than the first section 200 of the condenser 20 and is located within the range of the first section 200 of the condenser 20. That is, the length of the first section 100 of the evaporator 10 is shorter than the length of the first section 200 of the condenser 20.

[0064] Further reference Figure 6 In the second direction, the second section 101 and the third section 102 of the evaporator 10 at least partially overlap with the second section 201 and the third section 202 of the condenser 20. This forms a more compact nested structure.

[0065] Further reference Figure 3 and Figure 6 The condenser unit 2 further includes a condenser fan 21. The condenser fan 21 is disposed within the space enclosed by the U-shaped structure of the condenser. Further, in embodiments of this disclosure, the condenser unit 2 further includes a pair of condenser fans 21. As previously described, the first segment 200 of the condenser 20 forms a first inner corner 204 and a second inner corner 205 with the second segment 201 and the third segment 202, respectively, and the pair of condenser fans 21 are respectively disposed at the first inner corner 204 and the second inner corner 205. The condenser fan can be a common axial flow fan.

[0066] Further reference Figure 3 and Figure 6 The evaporator unit 1 further includes an evaporator fan 11, wherein the evaporator fan 11 is disposed within the space enclosed by the U-shaped structure of the evaporator 10. The evaporator fan may be, for example, a centrifugal fan, but it should be understood that it is not limited to this; any fan capable of causing air to flow along a desired path is acceptable. By disposing of the evaporator fan 11 within the space enclosed by the U-shaped structure of the evaporator 10, the overall structure becomes more compact.

[0067] Further reference Figure 3 and Figure 6 The vehicle air conditioner 1000 further includes a compressor 42, an expansion assembly 43, and a control board 44. The compressor 42 is located on the left side of the evaporator unit 1. The control board 44 is located on the right side of the evaporator unit 1. The expansion assembly 43 is located on the rear side of the evaporator unit, more specifically, on the rear side of the evaporator fan 11. Alternatively, the compressor 42 can be located on the right side of the evaporator unit 1, the control board 44 on the left side, and the expansion assembly 43 can be located within the internal space of the evaporator unit 1. The specific structure and function of the compressor 42, expansion assembly 43, and control board 44 will not be elaborated here; any component capable of performing conventional functions in the art can satisfy the requirements of this disclosure. That is, for example, any component capable of performing the basic functions of a compressor, an expansion valve, and a control board can satisfy the requirements of this disclosure.

[0068] Reference Figure 3 and Figure 7 To describe the flow path of the gas according to this disclosure, wherein Figure 7 According to this disclosure, the vehicle air conditioner 1000 is... Figure 4 A sectional view of the centerline AA. (e.g.) Figure 7 As shown, the condenser unit 2 is provided with a condenser air inlet 50 and a condenser air outlet 51. Figure 3 As shown in the embodiments of this disclosure, the condenser air inlet 50 includes a first sub-air inlet 500, a second sub-air inlet 501, and a third sub-air inlet 503. The first sub-air inlet 500 faces the windward direction. When the condenser fan 21 is running, air drawn in by the condenser fan 21 or air blown in due to the wind enters the condenser unit 2 through the condenser air inlet 50, exchanges heat with the condenser 20, and then flows out from the condenser air outlet 51. This path is called the second gas flow path. The condenser unit 2 causes the exchange of air with the outside air and is also called the outside unit.

[0069] The evaporator unit 1 is provided with an evaporator air inlet 52 and an evaporator air outlet 53. Air drawn in by the evaporator fan 11 enters the evaporator unit 1 through the evaporator air inlet 52, exchanges heat with the evaporator 10, and then flows out from the evaporator air outlet 53. This path is called the first gas flow path.

[0070] like Figure 7 As shown, the vehicle air conditioning 1000 also includes an ADB (Air Distribution Box) unit 3. The ADB unit 3 includes an ADB air inlet 31 and an ADB air outlet 32. The ADB air inlet 31 is connected to the evaporator air inlet 52, and the ADB air outlet 32 ​​is connected to the evaporator air outlet 53. Thus, air is drawn in through the ADB air inlet 31, passes through the evaporator air inlet 52, exchanges heat with the evaporator 10, and is then discharged from the evaporator air outlet 53 and further discharged into the passenger compartment through the ADB air outlet 32. The evaporator unit 1, which causes the exchange of air within the vehicle, is also referred to as the in-vehicle unit.

[0071] In the embodiments of this disclosure, the condenser air inlet 50, the evaporator air inlet 52, and the evaporator air outlet 53 are disposed in the chassis 41, and the condenser air outlet 51 is disposed in the outer casing 40.

[0072] Continue to refer to Figure 6 The condenser unit 2, evaporator unit 1, compressor 42, expansion assembly 43, and connecting pipes (not shown) of the vehicle air conditioner 1000 disclosed herein are generally located on the same plane. This makes subsequent maintenance more convenient, requiring only the removal of the corresponding outer casing.

[0073] In summary, this disclosure provides a vehicle air conditioner 1000, wherein the main components of the vehicle air conditioner 1000 are arranged in a planar layout on the chassis, which reduces the height of the vehicle air conditioner 1000 and facilitates maintenance. Furthermore, the components of the vehicle air conditioner 1000 are nested together, resulting in a very compact, symmetrical, and aesthetically pleasing layout.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and not to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure, and they should all be covered within the scope of the claims and specification of this disclosure.
