[0023] 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 only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0024] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0027] See also Figures 1 to 4 As shown, according to an embodiment of the present invention, an air conditioner is provided, including a shell 1, a first partition 2, a first fan (not shown in the figure) and a compressor 3. The first partition 2 is assembled in the shell 1 and divides the interior of the shell 1 into a first heat exchange chamber 4 and a compressor chamber 5. The first fan is installed in the first heat exchange chamber 4, and the compressor 3 is installed in the compressor chamber 5. A vent 6 is opened on the first partition 2, and the compressor chamber 5 is connected with the first heat exchange chamber 4 through the vent 6. An air outlet is formed on the shell 1, the compressor 3 is located on the air inlet side of the first fan, and the air outlet is located on the air outlet side of the first fan. When the first fan is in operation, the heat generated by the compressor 3 during operation can be sent out through the air outlet.

[0028] In this technical solution, when the air conditioner of the present application is applied to a bus, and the air outlet of the air conditioner is connected to the compartment of the bus, since the air vent 6 is opened on the first partition 2 of the air conditioner to connect the compressor chamber 5 and the first heat exchange chamber 4, and the compressor 3 and the air outlet are respectively located on the air inlet side and the air outlet side of the first fan, when the first fan is running, the heat generated by the compressor 3 during operation can be blown into the compartment for heating, so that the heat generated by the compressor 3 is fully utilized instead of being directly ignored. At the same time, when the first fan blows the heat generated by the compressor 3 during operation into the compartment for heating, it is equivalent to dissipating the heat of the compressor 3, which can prevent the compressor 3 from being in a high temperature environment for a long time, thereby extending the service life of the compressor 3.

[0029] It should be noted that when the air conditioner is in heating mode, the heat generated by the heat exchanger and the heat generated by the compressor will be sent into the car together, which also makes the air conditioner of the present application have stronger heating capacity and higher heating energy efficiency. Furthermore, when the air conditioner is in heating mode, it can also be shut down intermittently. During the shutdown period, only the first fan sends the waste heat generated by the compressor 3 into the car for heating. When the waste heat generated by the compressor 3 is almost consumed, the air conditioner is started to run in heating mode, which can also achieve the effect of reducing energy consumption and power consumption.

[0030] The relevant formulas for heat exchange in this application are as follows:

[0031] Q = Um·A·ΔTm;

[0032] Q is the total heat exchange, W;

[0033] Um——average heat transfer coefficient, W / (m 2 k);

[0034] A——heat exchange area, m 2 ;

[0035] ΔTm——average heat exchange temperature difference, ℃.

[0036] Among them, ℃ and K are both temperature units, and the conversion relationship between the two is 1℃=273K.

[0037] As a specific implementation, the compressor 3 is provided with a plurality of heat dissipation fins 7 which are distributed at intervals.

[0038] In this embodiment, by providing a plurality of heat dissipation fins 7 distributed at intervals on the compressor 3, the contact area between the compressor 3 and the air is increased, so that the first fan can deliver the heat generated by the compressor 3 into the vehicle compartment to a greater extent, thereby improving the utilization rate of the heat generated by the compressor 3.

[0039] See also Figures 1 to 3 As shown, the compressor 3 has one side facing the vent 6 and the other side facing away from the vent 6 , and each heat dissipation fin 7 is arranged on the side of the compressor 3 facing the vent 6 .

[0040] In this technical solution, since the compressor 3 can generate wind resistance, the airflow driven by the first fan mainly passes over the side of the compressor 3 facing the vent 6. When all the heat dissipation fins 7 are arranged on the side of the compressor 3 facing the vent 6, the heat generated by the compressor 3 can be delivered into the vehicle compartment to a greater extent while reducing the wind resistance.

[0041] See also Figure 3 As shown, each heat dissipation fin 7 extends from the compressor 3 to the vent 6, and each heat dissipation fin 7 is parallel to each other.

[0042] In this embodiment, when the heat dissipation fins 7 are parallel to each other, the wind resistance can be further reduced, thereby ensuring the air output of the first fan.

[0043] See also Figure 3 As shown, each heat dissipation fin 7 is provided with a plurality of fin branches 8 .

[0044] In this technical solution, a plurality of fin branches 8 are provided on each heat dissipating fin 7, which is equivalent to increasing the contact area between each heat dissipating fin 7 and the air, and is also equivalent to indirectly further increasing the contact area between the compressor 3 and the air. In this way, the first fan can further deliver the heat generated by the compressor 3 into the vehicle compartment to a greater extent, thereby further improving the utilization rate of the heat generated by the compressor 3.

[0045] More specifically, a heat insulation structure (not shown in the figure) is provided in the compressor chamber 5, and the heat insulation structure is used to prevent the heat generated by the compressor 3 from diffusing, so that the first fan can further deliver the heat generated by the compressor 3 into the vehicle compartment to a greater extent. Among them, the heat insulation structure can be two heat insulation boards, which are distributed up and down and extend from the compressor 3 to the vent 6, and each heat dissipation fin 7 is located between the upper and lower heat insulation boards, or the compressor 3 and each heat dissipation fin 7 are located between the upper and lower heat insulation boards. The heat insulation structure can also be a heat insulation frame, which has an opening toward the vent 6 and an opening facing away from the vent 6, and each heat dissipation fin 7 is located in the heat insulation frame, or the compressor 3 and each heat dissipation fin 7 are located in the heat insulation frame.

[0046] See also Figure 1 As shown, a second partition plate 9 is provided in the first heat exchange chamber 4, and the second partition plate 9 divides the first heat exchange chamber 4 into two accommodating chambers. Both accommodating chambers are connected to the ventilation port 6. There are two first fans, and the two first fans are respectively installed in the two accommodating chambers.

[0047] In this technical solution, by providing two first fans, the air volume delivered into the vehicle compartment can be increased, so that more heat generated by the compressor 3 can be delivered into the vehicle compartment, which can also achieve the purpose of improving the utilization rate of the heat generated by the compressor 3.

[0048] See also Figure 2 As shown, a filter screen 10 is provided at the vent 6 .

[0049] In this embodiment, the filter 10 is provided to filter the air flowing into the vehicle compartment from the compressor chamber 5, thereby ensuring the cleanliness of the air blown into the vehicle compartment.

[0050] As a specific implementation, a damper (not shown in the figure) is provided at the vent 6, and the damper is used to open or close the vent 6. When the air conditioner operates in heating mode, the damper opens the vent 6, and when the air conditioner operates in cooling mode, the damper closes the vent 6.

[0051] In this embodiment, if the air damper is not provided at the vent 6, when the air conditioner is in cooling mode, the first fan will also send the heat generated by the compressor 3 into the vehicle compartment, which is equivalent to mixing hot air with cold air, which will inevitably affect the cooling effect. When the air damper is provided at the vent 6, the vent 6 can be closed by the air damper when the air conditioner is in cooling mode, so that there will be no air circulation between the compressor chamber 5 and the first heat exchange chamber 4, which will not affect the cooling effect. When the air conditioner is in heating mode, the air damper is controlled to open the vent 6, and the first fan will send the heat generated by the compressor 3 into the vehicle compartment, thereby making full use of the heat generated by the compressor 3.

[0052] It should be noted that the control of the opening and closing of the damper can be accomplished with the aid of a motor. Specifically, the output shaft of the motor is connected to the damper, and the motor is controlled by the control device of the air conditioner. The setting program is that when the air conditioner is in cooling operation, the control device controls the motor to close the damper; when the air conditioner is in heating operation, the control device controls the motor to open the damper. Among them, the motor is preferably a stepper motor, which has more precise control, and the stepper motor can open and close the damper by rotating 90° forward and reverse.

[0053] Figure 4 The figure shows the working principle diagram of the air conditioner of the embodiment of the present invention. The air conditioner mainly includes four major parts, namely, a compressor 3, a first heat exchanger 13, a throttling element 14, and a second heat exchanger 15. The refrigerant circulates between the compressor 3, the first heat exchanger 13, the throttling element 14, and the second heat exchanger 15 to form a refrigerant circuit. The first heat exchanger 13 is installed in the first heat exchange chamber 4. A third partition 11 is also provided in the housing 1 of the air conditioner. A compressor chamber 5 is formed between the third partition 11 and the first partition 2. A second heat exchange chamber 12 is formed between the third partition 11 and the housing 1. The second heat exchanger 15 is installed in the second heat exchange chamber 12. Among them, the first heat exchanger 13 can be called an in-vehicle heat exchanger, and the second heat exchanger 15 can be called an out-of-vehicle heat exchanger. Furthermore, the air conditioner also includes a four-way valve (not shown in the figure), which allows the refrigerant flowing in the refrigerant circuit to be reversed, so that the air conditioner has cooling and heating functions. How the valve ports of the four-way valve and the compressor 3, the first heat exchanger 13, and the second heat exchanger 15 are connected is an existing mature technology and will not be repeated in this application.

[0054] The present invention also provides a vehicle, including a carriage and the aforementioned air conditioner, wherein the air outlet of the air conditioner is connected to the carriage. It should also be noted that the air conditioner of the present application is installed on the top of the carriage. In order to reduce the height of the air conditioner so that the vehicle does not look too high, the compressor 3 is installed in the compressor chamber 5 of the air conditioner in a horizontal manner, and the first heat exchange chamber 4, the compressor chamber 5, and the second heat exchange chamber 12 are arranged in sequence along the length direction of the carriage. Further, the compressor 3 extends along the width direction of the carriage. In order to ensure that the compressor 3 is covered by the airflow driven by the first fan as a whole, the width of the vent 6 is required to be greater than the axial length of the compressor 3, and the height of the vent 6 is greater than the radial height of the compressor 3. Finally, it should be noted that the air conditioner of the present application can be applied to buses and small passenger cars. In short, the air conditioner of the present application can be applied to vehicles with carriages and passengers in the carriages.
