Description

Technical Field

[0001] This utility model relates to the field of parking air conditioning technology, and in particular to a split-type parking air conditioner. Background Technology

[0002] Parking air conditioning is a new type of automotive air conditioning system that maintains a stable interior temperature when the car is stationary, providing a comfortable environment for passengers. Compared to in-vehicle air conditioning, parking air conditioning does not rely on the vehicle's engine power, reducing wear and tear on the engine and other parts, significantly improving fuel economy, and reducing vehicle emissions, thus benefiting environmental protection.

[0003] Most parking air conditioner outdoor units are installed on the outer side of the cab back. Currently, many truck models have different cab back structures, each model being different. Parking air conditioners operate in bumpy environments, and the outdoor unit is usually fixed to the load-bearing beam on the cab back. However, current air conditioner mounting brackets can only be installed on a single plane, limiting the installation location of the outdoor unit, or even making installation impossible. Some installers use shims to install the air conditioner, but this method of fixing the outdoor unit has reliability issues. Utility Model Content

[0007] An outdoor unit includes an outdoor unit housing and a condenser fan, a condenser, and a compressor disposed within the outdoor unit housing. The compressor is connected to the condenser, and one end of the condenser is connected to a connecting pipe. The other end of the connecting pipe passes through the indoor unit housing and is connected to the compressor. An air inlet is provided on the front surface of the outdoor unit housing, and the condenser fan is located between the air inlet and the condenser to guide external air to the condenser.

[0008] The mounting assembly includes two spaced-apart mounting brackets, each mounting bracket including a mounting strip and a support strip adjustablely connected to the connecting strip. The support strip has elongated holes spaced apart along its length. The bottom of the outdoor unit housing is connected to the connecting strip, and the portion of the connecting strip extending outside the outdoor unit housing has mounting holes that are adapted to the elongated holes.

[0009] After the outdoor unit housing is adjusted to the installation position, the mounting hole is aligned with the elongated hole, and a locking member is used to pass through the mounting hole and the elongated hole in sequence to fix the outdoor unit housing on the support bar.

[0010] In one possible implementation, the mounting strip includes an integrally connected first mounting edge and a second mounting edge, the first mounting edge and the second mounting edge being perpendicular to each other, and the first mounting edge having a plurality of first fixing holes spaced apart, the support strip having a locking hole at one end near the mounting strip, the locking hole being adapted to the first fixing hole, and the second mounting edge having a plurality of second fixing holes spaced apart.

[0011] In one possible implementation, a shock-absorbing pad is also included, which is connected to both ends of the connecting strip, and the shock-absorbing pad has through holes that are adapted to the mounting holes.

[0012] In one possible implementation, the shock-absorbing pad has a insertion groove extending through one end along its length, and the end of the connecting strip has an insertion portion that inserts into the insertion groove; wherein, after the insertion portion is inserted into the insertion groove, the through hole overlaps with the mounting hole.

[0013] In one possible implementation, the exterior housing has a partition plate that divides the interior of the exterior housing into a first chamber and a second chamber. The condenser and the condenser fan are located in the first chamber, and the compressor is located in the second chamber.

[0014] In one possible implementation, it further includes an expansion valve and a first pipeline disposed within the casing of the indoor unit, one end of the first pipeline being connected to the evaporator and the other end being connected to the end of the connecting pipe that passes through the casing of the indoor unit, and the expansion valve being disposed on the first pipeline.

[0015] In one possible implementation, an evaporator fan is also provided at the air inlet, the evaporator fan being connected to the interior unit housing for drawing air from inside the vehicle into the interior unit housing and guiding it to the evaporator.

[0016] In one possible implementation, the air inlet is provided with a plurality of fan-shaped air guide strips, and an air guide channel communicating with the air inlet is formed between two adjacent air guide strips.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The mounting assembly consists of two spaced-apart mounting brackets, each including a mounting strip and a connecting strip. The connecting strip is adjustable relative to the supporting strip. When installing the outdoor unit to the back of the cab, first fix the mounting strip to the back of the cab. Then, according to the installation height requirements, adjust the supporting strip to the installation height of the outdoor unit and fix it, thus securing the mounting assembly to the back of the cab. Next, place the outdoor unit housing on the supporting strip, at which point the connecting strip aligns with the supporting strip. Then, adjust the front and rear position of the outdoor unit housing according to the installation requirements. Once adjusted to the appropriate position, use the locking mechanism to pass through the mounting hole and the elongated hole in sequence, thereby installing the outdoor unit to the back of the cab. In other words, by using two mounting brackets in combination, the outdoor unit can be installed in non-planar locations, and its position can be adjusted according to actual needs. This method has a wide range of applications and high flexibility, thereby reducing the problems of installation limitations or inability to install due to the installation location.

[0034] Please refer to Figures 1 to 7 This application provides a split-type parking air conditioner, which includes an indoor unit 10, an outdoor unit 20, and mounting components. The indoor unit 10 includes an indoor unit housing 11 and an evaporator 12 disposed within the indoor unit housing 11. An air inlet and an air outlet 11a are respectively opened on opposite sides of the indoor unit housing 11, and the evaporator 12 is located between the air inlet and the air outlet 11a. The outdoor unit 20 includes an outdoor unit housing 21 and a condenser fan 24, a condenser 22, and a compressor 23 disposed within the outdoor unit housing 21. The compressor 23 is correspondingly connected to the condenser 22. One end of the condenser 22 is connected to a connecting pipe 50, and the other end of the connecting pipe 50 passes through the indoor unit housing and is connected to the compressor 23. An air inlet is opened on the front surface of the outdoor unit housing 21, and the condenser fan 24 is located between the air inlet and the condenser 22 to guide external air to the condenser 22. The mounting assembly includes two mounting brackets 30 spaced apart. Each mounting bracket 30 includes a mounting strip 31 and a support strip 32 that is adjustablely connected to a connecting strip 40. The support strip 32 has elongated holes spaced apart along its length. The bottom of the outdoor unit housing 21 is connected to the connecting strip 40. The portion of the connecting strip 40 extending outside the outdoor unit housing 21 has mounting holes 40a that are adapted to the elongated holes.

[0035] After the outdoor unit housing 21 is adjusted to the installation position, the mounting hole 40a is aligned with the elongated hole, and a locking device is used to pass through the mounting hole 40a and the elongated hole in sequence to fix the outdoor unit housing 21 onto the support bar 32. This allows the outdoor unit housing 21 to be adjusted within the range of the elongated hole in the support bar 32, adapting to different installation surface size requirements or installation angle needs, thus improving the versatility and adaptability of the installation of the air conditioner outdoor unit 20.

[0036] The split-type parking air conditioner of this embodiment consists of two spaced-apart mounting brackets 30. Each mounting bracket 30 includes a mounting strip 31 and a connecting strip 40. The connecting strip 40 is adjustable relative to the support strip 32. When installing the outdoor unit 20 to the back of the cab, the mounting strip 31 is first fixed to the back of the cab. Then, according to the installation height requirements, the support strip 32 is adjusted to the installation height of the outdoor unit 20 and fixed to complete the fixing of the mounting assembly to the back of the cab. Then, the outdoor unit housing 21 is placed on the support strip 32. At this time, the connecting strip 40 is connected to the support strip 32. Then, the front and rear positions of the outdoor unit housing 21 are adjusted according to the installation requirements. After adjusting to a suitable position, the locking piece is passed through the mounting hole 40a and the elongated hole in sequence to realize the installation of the outdoor unit 20 to the back of the cab. In other words, by using two mounting brackets 30 in combination, the outdoor unit 20 can be installed in a non-planar position, and its position can be adjusted according to actual needs. It has a wide range of applications and high flexibility, thereby reducing the problem of limited installation or inability to install the mounting brackets 30 due to the installation position.

[0037] In this embodiment, an air inlet and an air outlet 11a are respectively provided on both sides of the inner shell, and the evaporator 12 is placed between the two to form a direct airflow path. When indoor air enters from the air inlet, it can directly pass through the evaporator 12 for heat exchange, and then be discharged from the air outlet 11a. This reduces airflow resistance and energy loss, and improves the cooling efficiency of the air conditioner.

[0038] In addition, an air inlet is provided on the front surface of the outdoor unit casing 21, and the condenser fan 24 is located between the air inlet and the condenser 22, which can actively guide the outside air to the condenser 22. This design forms a forced convection heat dissipation mechanism, which can dissipate the heat generated by the condenser 22 during operation more efficiently than natural heat dissipation, ensuring that the condenser 22 is always in good working condition, thereby ensuring the stable operation of the entire air conditioning system.

[0039] In one possible implementation, the mounting strip 31 includes an integrally connected first mounting edge and a second mounting edge, which are perpendicular to each other. The first mounting edge has a plurality of first fixing holes 31a spaced apart. The support strip 32 has a locking hole 32a at one end near the mounting strip 31, which is adapted to the first fixing holes 31a. The second mounting edge has a plurality of second fixing holes spaced apart. That is, when installing the outdoor unit 20 on the back of the cab, the second mounting edge is first brought into contact with the back of the cab. Then, fasteners (e.g., bolts) are passed through the second fixing holes to fix the mounting strip 31 to the back of the cab. Next, according to the required installation height, the locking holes 32a of the support strip 32 are aligned with the corresponding first fixing holes 31a. Finally, fasteners (e.g., bolts) are passed through the locking holes 32a and the first fixing holes 31a in sequence to install the outdoor unit 20 onto the mounting assembly. Based on the above structure, regardless of the position and size of the pre-drilled mounting holes 40a on the vehicle, the mounting strip 31 can be adapted by selecting appropriate fixing holes, which improves the adaptability of the mounting components to different vehicle models and different installation environments, and expands the application range of the split-type parking air conditioner.

[0040] In one possible implementation, a shock-absorbing pad 60 is also included. The shock-absorbing pad 60 is connected to both ends of the connecting strip 40, and the shock-absorbing pad 60 has through holes 60b that are adapted to the mounting holes 40a. That is, after the shock-absorbing pad 60 is connected to both ends of the connecting strip 40, when the outdoor unit 20 is running (such as when the compressor 23 is working and generating mechanical vibration), the shock-absorbing pad 60 absorbs the vibration energy through its own elastic deformation, reducing the transmission of vibration from the connecting strip 40 to the mounting bracket 30 and the vehicle body. This can avoid problems such as loosening of mounting components and loosening of screws caused by long-term vibration, and is especially suitable for bumpy environments when the vehicle is driving, ensuring the installation stability of the air conditioning system. In addition, by making a through hole 60b on the shock-absorbing pad 60 that matches the mounting hole 40a, it can be ensured that during installation, the locking component (such as a bolt) can pass through both the mounting hole 40a and the through hole 60b at the same time. This not only fixes the shock-absorbing pad 60 to the connecting strip 40, but also does not affect the normal installation of the outdoor unit housing 21 through the installation component, thus avoiding damage to the stability of the original installation component due to the addition of additional shock-absorbing components.

[0041] In one possible implementation, the shock-absorbing pad 60 has a through-hole 60a extending along one end of its length, and the end of the connecting strip 40 has a plug-in portion 41 that engages with the through-hole 60a. After the plug-in portion 41 is inserted into the through-hole 60a, the through hole 60b overlaps with the mounting hole 40a. Thus, the through-hole 60a on the shock-absorbing pad and the plug-in portion 41 at the end of the connecting strip 40 form a mortise and tenon joint structure, allowing for initial positioning during installation simply by inserting the plug-in portion 41 into the through-hole 60a. This design simplifies the installation process of the shock-absorbing pad 60, eliminating the need for additional tools or complex operations, and significantly improving production assembly efficiency or replacement speed during after-sales maintenance.

[0042] In one possible implementation, the exterior housing 21 has a partition plate 25 inside, which divides the interior of the exterior housing 21 into a first chamber 21a and a second chamber 21b. The condenser 22 and the condenser fan 24 are located in the first chamber 21a, and the compressor 23 is located in the second chamber 21b.

[0043] For example, the partition plate 25 divides the interior of the outdoor unit housing 21 into a first chamber 21a and a second chamber 21b, allowing different functional components to be physically distributed independently. For instance, the mechanical vibration and heat generated during the operation of the compressor 23 can be confined within the second chamber 21b, reducing the impact on the heat dissipation efficiency of the condenser 22, while also preventing the airflow from the condenser fan 24 from directly impacting the compressor 23 components, thus improving the operational stability of each component. Furthermore, when a component in one chamber malfunctions (such as oil leakage from the compressor 23 or pipe damage in the condenser 22), the partition plate 25 can prevent the fault from spreading to another chamber. For example, a leak of lubricating oil from the compressor 23 will not directly contaminate the fins of the condenser 22, reducing secondary failures caused by cross-contamination and lowering maintenance complexity.

[0044] In one possible implementation, an expansion valve 14 and a first pipe 15 are also included, located inside the indoor unit casing. One end of the first pipe 15 is connected to the evaporator 12, and the other end is connected to the end of the connecting pipe 50 that passes through the indoor unit casing. The expansion valve 14 is mounted on the first pipe 15. Thus, the evaporator 12, connecting pipe 50, condenser 22, and compressor 23 are connected in series via the first pipe 15 to form a complete refrigeration cycle. Specifically, the high-pressure liquid refrigerant flowing from the condenser 22 enters the indoor unit casing via the connecting pipe 50 and flows to the evaporator 12 through the first pipe 15. The expansion valve 14, mounted on the first pipe 15, can throttle and reduce the pressure of the high-pressure refrigerant, converting it into a low-pressure liquid / gas mixture, creating conditions for the evaporator 12 to absorb heat through evaporation.

[0045] In one possible implementation, an evaporator fan 13 is also included at the air inlet. The evaporator fan 13 is connected to the inner unit casing and is used to draw air from inside the vehicle into the inner unit casing and guide it to the evaporator 12. In this way, by drawing air from inside the vehicle through the evaporator fan 13, the air is evenly blown to all areas of the evaporator 12, avoiding the waste of some heat exchange area due to dead airflow.

[0046] In one possible implementation, the air inlet is provided with a plurality of fan-shaped air guide strips 70, and an air guide channel communicating with the air inlet is formed between two adjacent air guide strips 70.

[0047] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
