Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing a parking air conditioner. Background Technology

[0002] With the rapid development of my country's economy, the number of trucks used for land transportation continues to increase. To improve the driving environment, truck cabs are usually equipped with onboard air conditioning. Onboard air conditioning includes parking air conditioning, which is powered by a battery so that it can operate when the vehicle is parked.

[0003] Typically, trucks are parked at night, and the driver rests on a berth in the cab. The parking air conditioner operates during this time, providing a relatively cool sleeping environment for the driver. However, while the parking air conditioner is running, the outdoor fan in the outdoor unit generates considerable vibration. Coupled with the confined space and complex environment of the cab, this can easily produce significant noise, which will affect the driver's sleep.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, the problem that the outdoor fan of the existing parking air conditioner easily generates a lot of noise, which affects the driver's sleep.

[0006] In a first aspect, the present invention provides a parking air conditioner, the parking air conditioner including an outdoor unit, the outdoor unit including a heat dissipation unit, the heat dissipation unit including a housing and a condenser disposed in the housing, the outer wall of the housing being coated with a radiation cooling material layer, a heat conduction cavity being formed between the inner wall of the housing and the condenser, the heat conduction cavity being filled with a heat conduction liquid, the heat conduction liquid being used to conduct the heat of the condenser to the housing.

[0007] In the preferred embodiment of the above-mentioned parking air conditioner, the heat conduction cavity is equipped with a disturbance device, which is used to realize the flow of the heat conduction fluid.

[0008] In the preferred embodiment of the above-mentioned parking air conditioner, the disturbance device includes a circulating pump disposed within the heat conduction cavity.

[0009] In the preferred technical solution of the above-mentioned parking air conditioner, there are multiple circulation pumps, and the multiple circulation pumps are arranged at one or more height positions in the heat conduction cavity.

[0010] In the preferred embodiment of the above-mentioned parking air conditioner, the inlet and outlet of the circulation pump at least at a height position are oriented horizontally.

[0011] In the preferred embodiment of the above-mentioned parking air conditioner, the inlet and outlet of the circulation pump at least at a height position are oriented vertically.

[0012] In the preferred technical solution of the above-mentioned parking air conditioner, at least two circulation pumps are provided at each height position, and the circulation pumps at each height position are evenly distributed around the condenser.

[0013] In the preferred technical solution of the above-mentioned parking air conditioner, the heat transfer fluid is water or ethylene glycol solution.

[0014] When the above technical solution is adopted, the parking air conditioner includes an outdoor unit, the outdoor unit includes a heat dissipation unit, the heat dissipation unit includes a housing and a condenser installed inside the housing, the outer wall of the housing is coated with a radiation cooling material layer, a heat conduction cavity is formed between the inner wall of the housing and the condenser, the heat conduction cavity is filled with a heat conduction liquid, and the heat conduction liquid is used to conduct the heat of the condenser to the housing.

[0015] With this design, when the parking air conditioner is operating, the heat dissipated by the condenser in the outdoor unit is transferred to the housing via the heat-conducting fluid in the heat-conducting chamber. The heat transferred to the housing is then dissipated into the atmosphere by radiating electromagnetic waves with wavelengths of 8 to 13 micrometers through a layer of radiant cooling material on the outer wall of the housing. In other words, the heat from the condenser no longer relies on the airflow generated by the outdoor fan for dissipation, avoiding the significant noise generated by the outdoor fan that could disturb the driver's sleep. Furthermore, compared to simply coating the outer wall of the condenser with a layer of radiant cooling material, this method increases the heat dissipation area and improves the cooling effect.

[0016] It should be noted that the radiation cooling material layer can be a nano-scale TiO2 material layer, a ceramic vacuum microsphere material layer, a barium sulfate material layer, a polyvinyl fluoride material layer, a polyethylene terephthalate material layer, or a polydimethylsiloxane material layer, etc.

[0017] Preferably, the heat-conducting cavity is equipped with a disturbance device, which is used to realize the flow of the heat-conducting fluid.

[0018] With this setup, the heat transfer fluid in the heat transfer chamber can be circulated through the disturbance device, improving the heat exchange efficiency between the heat transfer fluid and the condenser and housing, ensuring the heat dissipation effect of the condenser, and thus ensuring the cooling effect of the parking air conditioner.

[0019] Preferably, the disturbance device includes a circulating pump disposed within the heat-conducting cavity.

[0020] The circulation pump enables the heat transfer fluid to flow in a specific direction within the heat transfer cavity, ensuring the directional flow of the heat transfer fluid within the heat transfer cavity.

[0021] Preferably, there are multiple circulating pumps, which are arranged at one or more height positions within the heat-conducting cavity.

[0022] By setting up multiple circulation pumps, the flow range of the heat transfer fluid in the heat transfer cavity can be expanded, the uniformity of the heat transfer fluid flow can be improved, and the temperature of the heat transfer fluid in various parts of the heat transfer cavity can be made more uniform, thus ensuring the heat dissipation consistency at different locations of the condenser.

[0023] Preferably, the inlet and outlet of at least one circulation pump at a height position are oriented horizontally.

[0024] This configuration increases the horizontal flow range of the heat transfer fluid and promotes the mixing of heat transfer fluid at different locations at the same height.

[0025] Preferably, the inlet and outlet of at least one circulation pump at a height position are oriented vertically.

[0026] This design increases the vertical flow range of the heat transfer fluid and promotes the mixing of heat transfer fluid at different heights within the same area of ​​the heat transfer cavity.

[0027] Preferably, at least two circulation pumps are provided at each height position, and the circulation pumps at each height position are evenly distributed around the condenser.

[0028] This design further promotes the flow and mixing of the heat transfer fluid at different locations within the heat transfer cavity, improves the uniformity of the heat transfer fluid flow, and makes the temperature of the heat transfer fluid in different locations within the heat transfer cavity tend to be consistent, thus ensuring consistent heat dissipation at different locations of the condenser.

[0029] In a second aspect, the present invention provides a parking air conditioner, the parking air conditioner including an outdoor unit, the outdoor unit including a heat dissipation unit including a condenser, and the outer wall of the condenser being coated with a radiation cooling material layer.

[0030] In the preferred technical solution of the above-mentioned parking air conditioner, the outdoor unit further includes an outdoor fan and a night determination device. The night determination device is used to determine whether it is nighttime, and the outdoor fan is used to blow air onto the condenser during the day.

[0031] When the above technical solution is adopted, the parking air conditioner includes an outdoor unit, the outdoor unit includes a heat dissipation unit, the heat dissipation unit includes a condenser, and the outer wall of the condenser is coated with a layer of radiation cooling material.

[0032] With this configuration, when the parking air conditioner is operating, the heat emitted by the condenser in the outdoor unit is dissipated into the atmosphere by radiating electromagnetic waves with wavelengths of 8 to 13 micrometers through a layer of radiant cooling material on the outer wall of the condenser. In other words, the heat from the condenser no longer relies on the airflow generated by the outdoor fan for heat dissipation, thus avoiding the situation where the outdoor fan generates significant noise during operation, which could affect the driver's sleep.

[0033] Preferably, the outdoor unit also includes an outdoor fan and a nighttime determination device, which is used to determine whether it is nighttime, and the outdoor fan is used to blow air onto the condenser during the day.

[0034] With this setup, when the parking air conditioner operates at night, the night-time detection device determines that the current period is nighttime. The heat emitted by the condenser is dissipated into the atmosphere through the radiative cooling material layer on the outer wall of the condenser, radiating electromagnetic waves with wavelengths of 8 to 13 micrometers. When the parking air conditioner operates during the day, the night-time detection device determines that the current period is daytime, the outdoor fan operates, and the condenser dissipates heat using the airflow generated by the outdoor fan. In this way, efficient heat dissipation of the condenser is ensured both day and night, and the noise generated by the outdoor fan during the operation of the parking air conditioner at night, which could disturb the driver's sleep, is avoided.

[0035] It should be noted that the night detection device can be a controller including a light recognition device, a controller including a clock, or other suitable night detection devices. Attached Figure Description

[0049] First, those skilled in the art should understand that the embodiments described below are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0050] It should be noted that in the description of this utility model, terms such as "left" and "right," which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] Based on the problem mentioned in the background art that the outdoor fan of the existing parking air conditioner is prone to generating large noise and affecting the driver's sleep, this utility model provides a parking air conditioner. The parking air conditioner includes an outdoor unit, which includes a heat dissipation unit. The heat dissipation unit includes a housing and a condenser installed inside the housing. The outer wall of the housing is coated with a radiation cooling material layer. A heat conduction cavity is formed between the inner wall of the housing and the condenser. The heat conduction cavity is filled with a heat conduction liquid, which is used to conduct the heat of the condenser to the housing.

[0053] With this design, when the parking air conditioner is operating, the heat dissipated by the condenser in the outdoor unit is transferred to the housing via the heat-conducting fluid in the heat-conducting chamber. The heat transferred to the housing is then dissipated into the atmosphere by radiating electromagnetic waves with wavelengths of 8 to 13 micrometers through a layer of radiant cooling material on the outer wall of the housing. In other words, the heat from the condenser no longer relies on the airflow generated by the outdoor fan for dissipation, avoiding the significant noise generated by the outdoor fan that could disturb the driver's sleep. Furthermore, compared to simply coating the outer wall of the condenser with a layer of radiant cooling material, this method increases the heat dissipation area and improves the cooling effect.

[0054] The following reference Figures 1 to 10 This article will provide a detailed introduction to the parking air conditioner of this utility model.

[0057] In the first embodiment of this utility model, such as Figure 1 and Figure 2As shown, the parking air conditioner includes an outdoor unit 1 and an indoor unit 2, which are distributed vertically and integrally connected. The outdoor unit 1 includes a housing 11, within which a heat insulation cover 12 is installed. An evaporator (not shown) is located inside the heat insulation cover 12. A compressor 13, an electrical control box 14, an electronic expansion valve (not shown), and a heat dissipation unit 15 are located outside the heat insulation cover 12. The compressor 13 and electrical control box 14 are located on the left side of the heat insulation cover 12, and the heat dissipation unit 15 is located on the right side of the heat insulation cover 12. The indoor unit 2 includes an internal fan (not shown) installed within it. The heat dissipation unit 15 includes a housing 151 and a condenser 152 installed within the housing 151. The top plate and three side plates of the housing 151 form part of the housing 11. The outer wall of the housing 151 is coated with a radiant cooling material layer 153; specifically, the outer surfaces of the top plate and the three side plates of the housing 151 are coated with the radiant cooling material layer 153. A heat-conducting cavity 154 is formed between the inner wall of the housing 151 and the condenser 152. The heat-conducting cavity 154 is filled with a heat-conducting liquid (not shown in the figure), which is used to conduct heat from the condenser 152 to the housing 151. The compressor 13, condenser 152, electronic expansion valve, and evaporator are connected by pipes to form a circulation loop. The heat-conducting liquid can be water or ethylene glycol solution, or other suitable heat-conducting liquid. The radiative cooling material layer can be a nano-scale TiO2 material layer, a ceramic vacuum microsphere material layer, a barium sulfate material layer, a polyvinyl fluoride material layer, a polyethylene terephthalate material layer, or a polydimethylsiloxane material layer, etc.

[0058] During operation, the low-temperature, low-pressure gaseous refrigerant is compressed by compressor 13 into a high-temperature, high-pressure gaseous refrigerant. This high-temperature, high-pressure gaseous refrigerant flows into condenser 152 and condenses there, becoming a high-temperature, high-pressure liquid refrigerant. After being throttled and depressurized by an electronic expansion valve, the liquid refrigerant enters the evaporator and evaporates back into a low-temperature, low-pressure gaseous refrigerant. Finally, the low-temperature, low-pressure gaseous refrigerant re-enters compressor 13 for compression. During the condensation process in condenser 152, the high-temperature, high-pressure gaseous refrigerant releases a large amount of heat. This heat is dissipated through condenser 152 into the heat-conducting cavity and transferred to the housing 151 via the heat-conducting liquid. Ultimately, it is dissipated into the atmosphere through the radiation cooling material layer 153 by radiating electromagnetic waves with wavelengths from 8 to 13 micrometers.

[0059] With this design, when the parking air conditioner is operating, the heat from the condenser 152 no longer relies on the airflow generated by the external fan for dissipation, thus avoiding the significant noise generated by the external fan that could disturb the driver's sleep. Furthermore, compared to coating the outer wall of the condenser 152 with a layer of radiant cooling material, this increases the heat dissipation area and improves the cooling effect.

[0060] In the second embodiment of this utility model, such as Figure 3and Figure 4 As shown, unlike the first embodiment, the heat-conducting cavity 154 is equipped with a disturbance device to facilitate the flow of the heat-conducting fluid. Specifically, the disturbance device includes four circulating pumps 155 disposed within the heat-conducting cavity 154. The four circulating pumps 155 are positioned at the same height within the heat-conducting cavity 154 and are distributed to the left of the condenser 152. The outlets of all four circulating pumps 155 face upwards, and the inlets of all four circulating pumps 155 face downwards.

[0061] When the parking air conditioner is operating, the circulation pump 155 works. The heat transfer fluid near the bottom of the heat transfer cavity 154 enters the circulation pump 155 and flows upwards, while the heat transfer fluid near the top of the heat transfer cavity 154 flows downwards. This creates vertical convection flow of the heat transfer fluid within the heat transfer cavity 154, resulting in a more uniform temperature of the heat transfer fluid, improving heat transfer efficiency, and promoting heat dissipation from the condenser 152. By setting multiple circulation pumps 155, the flow range of the heat transfer fluid within the heat transfer cavity 154 can be expanded, improving the uniformity of the heat transfer fluid flow and ensuring that the temperature of the heat transfer fluid throughout the heat transfer cavity 154 tends to be consistent, thus guaranteeing consistent heat dissipation from different locations on the condenser 152.

[0062] In the third embodiment of this utility model, such as Figure 5 and Figure 6 As shown, unlike the second embodiment, the disturbance device includes eight circulating pumps 155 disposed within the heat conduction cavity 154. The eight circulating pumps 155 are positioned at the same height within the heat conduction cavity 154, with four circulating pumps 155 distributed on the left side of the condenser 152 and four circulating pumps 155 distributed on the right side of the condenser 152. The outlets of all eight circulating pumps 155 are horizontally oriented towards the inner wall of the housing 151, and the inlets of all eight circulating pumps 155 are horizontally oriented towards the condenser 152.

[0063] This configuration allows the heat transfer fluid to flow more effectively over the surface of the condenser 152, thereby improving the heat dissipation efficiency of the condenser 152.

[0064] In the fourth embodiment of this utility model, such as Figure 7 As shown, unlike the third embodiment, the disturbance device includes twelve circulating pumps 155 disposed within the heat conduction cavity 154. The twelve circulating pumps 155 are disposed at the same height within the heat conduction cavity 154 and are evenly distributed around the condenser 152.

[0065] This design further promotes the flow and mixing of heat transfer fluid at different locations within the heat transfer cavity 154, improves the uniformity of heat transfer fluid flow, and makes the temperature of the heat transfer fluid at various locations within the heat transfer cavity 154 tend to be consistent, thus ensuring consistent heat dissipation at different locations of the condenser 152.

[0066] In the fifth embodiment of this utility model, as Figure 8 As shown, unlike the fourth embodiment, the disturbance device includes thirty-six circulating pumps 155 disposed within the heat conduction cavity 154. The thirty-six circulating pumps 155 are disposed at three different height positions within the heat conduction cavity 154, with twelve circulating pumps 155 disposed at each height position, and the twelve circulating pumps 155 at the same height position are evenly distributed around the condenser 152.

[0067] This design allows for better flow of heat transfer fluid at different heights, further improving the uniformity of the flow and ensuring that the temperature of the heat transfer fluid in the heat transfer cavity 154 is consistent, thus guaranteeing consistent heat dissipation at different locations of the condenser 152.

[0068] In the sixth embodiment of this utility model, such as Figure 9 and Figure 10 As shown, the parking air conditioner includes an outdoor unit 1 and an indoor unit 2, which are distributed vertically and integrally connected. The outdoor unit 1 includes a housing 11, inside which is a heat insulation cover 12. An evaporator (not shown) is housed inside the heat insulation cover 12. A compressor 13, an electrical control box 14, an electronic expansion valve (not shown), and a heat dissipation unit 15 are located outside the heat insulation cover 12. The compressor 13 and electrical control box 14 are located on the left side of the heat insulation cover 12, and the heat dissipation unit 15 is located on the right side of the heat insulation cover 12. The indoor unit 2 includes an internal fan (not shown). The heat dissipation unit 15 includes a condenser 152, the outer wall of which is coated with a radiation cooling material layer 153. The compressor 13, condenser 152, electronic expansion valve, and evaporator are connected by pipes to form a circulation loop. The radiation cooling material layer can be a nano-scale TiO2 material layer, a ceramic vacuum microsphere material layer, a barium sulfate material layer, a polyvinyl fluoride material layer, a polyethylene terephthalate material layer, or a polydimethylsiloxane material layer, etc.

[0069] During operation, the low-temperature, low-pressure gaseous refrigerant is compressed by compressor 13 into a high-temperature, high-pressure gaseous refrigerant. This high-temperature, high-pressure gaseous refrigerant flows into condenser 152 and condenses there, becoming a high-temperature, high-pressure liquid refrigerant. The high-temperature, high-pressure liquid refrigerant then passes through an electronic expansion valve for throttling and pressure reduction before entering the evaporator to evaporate and become a low-temperature, low-pressure gaseous refrigerant. Finally, the low-temperature, low-pressure gaseous refrigerant re-enters compressor 13 for compression. During the condensation process of the high-temperature, high-pressure gaseous refrigerant into a high-temperature, high-pressure liquid refrigerant in condenser 152, a large amount of heat is released. This heat is dissipated into the atmosphere through the radiation cooling material layer 153 on the outer wall of condenser 152, radiating electromagnetic waves with wavelengths from 8 to 13 micrometers.

[0070] With this setup, when the parking air conditioner is working, the heat from the condenser 152 no longer needs to be dissipated by the airflow generated by the external fan, thus avoiding the situation where the external fan generates a lot of noise during operation, which could affect the driver's sleep.

[0071] In another feasible embodiment, based on the sixth embodiment, the outdoor unit 1 further includes an outdoor fan and a night-determination device. The night-determination device is used to determine whether it is currently nighttime, and the outdoor fan is used to blow air onto the condenser 152 during the day. It should be noted that the night-determination device can be a controller including a light recognition device, a controller including a clock, or other suitable night-determination devices, etc.

[0072] When the parking air conditioner is started, the night detection device first determines whether it is nighttime. If it is nighttime, the external fan is turned off, and the heat released by the condenser 152 is dissipated into the atmosphere by radiating electromagnetic waves with wavelengths of 8 to 13 micrometers through the radiation cooling material layer 153 on its outer wall. If it is daytime, the external fan is turned on, and the condenser 152 dissipates heat by means of the airflow generated by the external fan.

[0073] With this setup, efficient heat dissipation of the condenser 152 can be ensured both day and night, and the noise generated by the outdoor fan during the operation of the parking air conditioner at night, which would affect the driver's sleep, is avoided.

[0074] In some other feasible embodiments, unlike the first to fifth embodiments described above, the circulation pump 155 is replaced with an agitator impeller.

[0075] It should be noted that although the above embodiments are described in conjunction with an integrated parking air conditioner, this does not constitute a limitation on the present invention. The parking air conditioner of the present invention can also be a split-type parking air conditioner.

[0076] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
