Technical Field

[0001] This application relates to the field of vehicle cooling technology, and in particular to a vehicle cooling device and a cooling vehicle. Background Technology

[0002] Vehicle-mounted cooling equipment is an important component of a cooling vehicle. It is installed on the vehicle body and is used to provide mobile cooling to heat-generating equipment (such as military and civilian lasers, radars, and high-power electronic devices) to cool and dissipate heat, preventing these heat-generating devices from overheating during operation and affecting normal operation.

[0003] However, traditional vehicle-mounted cooling equipment has weak cooling capacity and cannot effectively meet cooling needs. Utility Model Content

The compression cooling piping is thermally coupled to the heat-generating equipment and is connected to different heat exchange channels of the refrigerant piping and the heat exchanger, so that the cooling liquid in the compression cooling piping carries away the heat of the heat-generating equipment and flows through the heat exchanger, where it transfers heat to the refrigerant in the refrigerant piping, thereby cooling the heat-generating equipment.

[0013] In some embodiments, the heat exchanger includes a first liquid inlet, a second liquid inlet, and multiple rows of heat exchange channels, all of which are connected to the first and second liquid inlets. A portion of the multiple rows of heat exchange channels is configured as a condenser, and another portion is configured as a surface cooler. And / or, heat exchangers of multiple heat dissipation systems are disposed on opposite sides of the fan, and the heat exchangers located on opposite sides of the fan gradually move away from each other along the direction of the fan-driven gas outflow.

[0019] In some embodiments, the fan is a variable frequency fan; and / or, the cooling system includes vibration damping components that clamp the fan to reduce its vibration.

[0020] In some embodiments, the vehicle cooling device further includes an electronic control system disposed within the housing and located at the outermost position within the housing.

[0021] In some embodiments, the housing includes a back panel, a front panel, and two side panels. The two side panels are connected to opposite ends of the back panel, and the front panel is connected between the two side panels and to the back panel. The front panel includes a vertically arranged upright plate and an inclined plate, and the upright plate is connected to the back panel through the inclined plate.

[0022] In some embodiments, the front panel includes a plurality of inclined plates connected sequentially along the direction from the back panel to the uprights, with different inclination angles.

[0023] In addition, the cooling vehicle provided in this application includes a vehicle body, and also includes an on-board cooling device according to any embodiment, which is disposed on the vehicle body.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0054] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0055] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0057] In this application, unless otherwise stated, “multiple” means at least two, that is, including cases of two and at least three.

[0058] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0059] To better meet cooling requirements, this application improves the structure of the vehicle-mounted cooling equipment and provides a vehicle-mounted cooling equipment and a cooling vehicle.

[0060] Figures 1-7 An exemplary illustration is shown of a cooling vehicle and its on-board cooling equipment as described in this application.

[0061] in, Figure 1 The structure of a portion of the cooling vehicle is shown. See also... Figure 1In this application, the cooling vehicle 100 includes a vehicle body 102 and an onboard cooling device 101. The vehicle body 102 typically includes a running gear (not shown) to enable the vehicle to move, allowing the cooling vehicle 100 to flexibly move to different locations to cool different heat-generating devices 200 (see figure). Figure 7 Cooling and heat dissipation are achieved by the vehicle-mounted cooling device 101, which is installed on the vehicle body 102 and is used to deliver cooling liquid to the heat-generating device 200 so that the cooling liquid can carry away the heat of the heat-generating device 200, thereby achieving cooling and heat dissipation of the heat-generating device 200.

[0062] Depend on Figure 1 As can be seen, in some embodiments, the cooling vehicle 100 includes not just one on-board cooling device 101, but multiple on-board cooling devices 101. These multiple on-board cooling devices 101 are all disposed on the vehicle body 102 and arranged along the length and / or width direction of the vehicle body 102. Thus, the larger number of on-board cooling devices 101 provides greater cooling capacity, and therefore, the cooling vehicle 100 has a stronger cooling capacity. It is understood that the length and width directions of the vehicle body 102 are also the front-rear and left-right directions of the cooling vehicle 100.

[0063] As an example of a cooling vehicle 100 including multiple on-board cooling devices 101, see [link to relevant documentation]. Figure 1 In some embodiments, the cooling vehicle 100 includes two sets of on-board cooling devices 101, each set including at least one on-board cooling device 101, and the two sets of on-board cooling devices 101 are arranged at intervals along the width direction of the vehicle body 102, forming a passage 103 between the two sets of on-board cooling devices 101. Since the passage 103 allows staff to pass through and maintain the on-board cooling devices 101, the convenience of vehicle maintenance can be improved.

[0064] The number of vehicle-mounted cooling devices 101 in each group is unlimited; there can be one or more. For example, see... Figure 1 In some embodiments, both sets of vehicle-mounted cooling devices 101 include multiple vehicle-mounted cooling devices 101, and the multiple vehicle-mounted cooling devices 101 in the same set are arranged side by side along the length of the vehicle body 102. In this way, the number of vehicle-mounted cooling devices 101 on the cooling vehicle 100 is greater, which can further improve the cooling capacity of the cooling vehicle 100.

[0065] Figures 2-7 The structure and working principle of the vehicle-mounted cooling device 101 are further illustrated.

[0066] See Figures 2-7In this application, the vehicle-mounted cooling device 101 includes a housing 1 and multiple heat dissipation systems 3. The housing 1 has multiple vents 17. Each of the multiple heat dissipation systems 3 includes a fan 4 and a cooling system 5. The fans 4 of the multiple heat dissipation systems 3 are respectively located at the multiple vents 17 to drive gas in the housing 1 to flow out through the multiple vents 17. The cooling systems 5 of the multiple heat dissipation systems 3 are all located in the housing 1 and are connected in parallel to provide cooling liquid to the heat-generating device 200 to absorb the heat from the heat-generating device 200. The absorbed heat is then carried away by the gas driven by the fans 4, thereby cooling the heat-generating device 200.

[0067] Based on the above configuration, the vehicle-mounted cooling device 101 can deliver cooling liquid to the heat-generating device 200 through the cooling system 5 of the heat dissipation system 3, and the heat absorbed by the heat-generating device 200 by the fan 4 of the heat dissipation system 3 can be carried away. Thus, with the cooperation of the fan 4 of the heat dissipation system 3 and the cooling system 5, the heat-generating device 200 can be cooled and dissipated.

[0068] Traditional vehicle-mounted cooling equipment 101 adopts a single-system design, that is, it only includes one heat dissipation system 3. In this case, the vehicle-mounted cooling equipment 101 can only rely on this one heat dissipation system 3 to cool and dissipate heat from the heat-generating equipment 200. The cooling capacity is small and fixed, and the liquid cooling range is narrow. Therefore, the cooling capacity is weak and it is difficult to effectively meet the cooling requirements.

[0069] The above solution breaks through the traditional design concept of a single-system vehicle cooling device 101, and innovatively adopts a multi-system design. This means that the vehicle cooling device 101 no longer includes only one heat dissipation system 3, but rather multiple heat dissipation systems 3 connected in parallel. Thus, the vehicle cooling device 101 is no longer limited to relying on a single heat dissipation system 3 to cool the heat-generating device 200; instead, it can flexibly rely on one or more heat dissipation systems 3 to cool the heat-generating device 200 according to actual needs. In other words, it can flexibly operate as a single system or multiple systems. For example, if cooling demand... If the cooling capacity is high, at least two of the multiple cooling systems 3 can operate to provide a larger cooling capacity and effectively meet the corresponding higher cooling demand. If the cooling demand is low, only one of the multiple cooling systems 3 can operate to provide a smaller cooling capacity and effectively meet the corresponding lower cooling demand. In this way, the cooling capacity of the vehicle cooling equipment 101 and the cooling vehicle 100 can be increased, and the cooling capacity of the vehicle cooling equipment 101 and the cooling vehicle 100 can be adjusted, effectively expanding the liquid cooling range of the vehicle cooling equipment 101 and the cooling vehicle 100, thereby effectively enhancing the cooling capacity of the vehicle cooling equipment 101 and the cooling vehicle 100.

[0070] This explanation uses the case where the cooling capacity (or heat dissipation) of a single cooling system 3 is 65 kW as an example. If the cooling capacity of a single cooling system 3 is 65 kW, then the vehicle-mounted cooling device 101 with a dual-system design (i.e., having two parallel cooling systems 3) can flexibly switch between 65 and 130 kW of cooling capacity. The cooling vehicle 100 with six vehicle-mounted cooling devices 101 can flexibly switch between 65 and 780 kW of cooling capacity. Therefore, the cooling capacity is larger and more adjustable, the liquid cooling range is wider, and the cooling capacity is stronger.

[0071] The aforementioned vehicle-mounted cooling device 101 with multiple heat dissipation systems 3 has a stronger cooling capacity not only compared to a single vehicle-mounted cooling device 101 with only a single heat dissipation system 3, but also compared to the same number of vehicle-mounted cooling devices 101 with only a single heat dissipation system 3. This is because, with a vehicle-mounted cooling device 101 having multiple heat dissipation systems 3, when only some of the heat dissipation systems 3 are working, the vents 17 corresponding to the other heat dissipation systems 3 can also provide airflow to the working heat dissipation systems 3, resulting in a larger ventilation area, greater heat dissipation, and stronger cooling capacity. In contrast, with the same number of vehicle-mounted cooling devices 101 with only a single heat dissipation system 3, when only some of the vehicle-mounted cooling devices 101 are working, the vents 17 of the other vehicle-mounted cooling devices 101 do not provide airflow to the working vehicle-mounted cooling devices 101, resulting in a smaller ventilation area, less heat dissipation, and weaker cooling capacity. From another perspective, a vehicle-mounted cooling device 101 consisting only of a single heat dissipation system 3 would require a larger area to achieve the same heat dissipation capacity, making it impossible to arrange the same number of vehicle-mounted cooling devices 101 on the cooling vehicle 100. For example, in Figure 1 When the vehicle-mounted cooling equipment 101 adopts a dual-system design, six vehicle-mounted cooling equipment 101 can be installed on the vehicle body 102. However, if the vehicle-mounted cooling equipment 101 adopts a single-system design with the same heat dissipation capacity, the vehicle-mounted cooling equipment 101 will occupy a larger area, resulting in the inability to arrange six more vehicle-mounted cooling equipment 101 on the vehicle body 102. The number of vehicle-mounted cooling equipment 101 is reduced, therefore, the cooling capacity is smaller, the liquid cooling range is narrower, and the cooling capacity is weaker.

[0072] It is evident that by configuring the vehicle-mounted cooling device 101 as including multiple parallel heat dissipation systems 3, the vehicle-mounted cooling device 101 can flexibly switch between single-system operation mode and multi-system operation mode, making the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100 large and adjustable, effectively increasing the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100, expanding the liquid cooling range of the vehicle-mounted cooling device 101 and the cooling vehicle 100, and thus effectively enhancing the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100, better meeting the cooling requirements.

[0073] Moreover, since the vehicle-mounted cooling equipment 101 can flexibly switch between single-system operation mode and multi-system operation mode to better match different cooling needs, it is also conducive to reducing energy waste and effectively saving energy.

[0074] It is evident that by configuring the vehicle-mounted cooling device 101 as a heat dissipation system 3 that includes multiple parallel connections, the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100 can be enhanced and energy-efficient.

[0075] The heat dissipation system 3 provides cooling liquid to the heat-generating equipment 200 through the cooling system 5. The cooling system 5 can adopt various structural forms.

[0076] For example, see Figure 7 In some embodiments, the cooling system 5 includes an air-cooled system 7, which includes an air-cooled pipe 71 and a surface cooler 72. The air-cooled pipe 71 is thermally coupled to the heat-generating equipment 200, and the surface cooler 72 is disposed on the air-cooled pipe 71 so that the cooling liquid in the air-cooled pipe 71 carries away the heat of the heat-generating equipment 200 and transfers heat to the gas driven by the fan 4 when flowing through the surface cooler 72, thereby cooling the heat-generating equipment 200.

[0077] The aforementioned air-cooling system 7 supplies cooling liquid to the heat-generating equipment 200 through air-cooling pipes 71. The cooling liquid in the air-cooling pipes 71 absorbs heat from the heat-generating equipment 200, and the absorbed cooling liquid flows through the surface cooler 72 on the air-cooling pipes 71. At the surface cooler 72, heat is transferred to the gas driven by the fan 4, which then carries away the heat, thus cooling the heat-generating equipment 200. The cooling process achieved by the air-cooling system 7 can be called the air-cooling process, and the corresponding operating mode can be called the air-cooling mode. This air-cooling mode is particularly effective in meeting cooling requirements under low ambient temperatures, enabling the cooling system 5 to achieve better cooling performance even in low ambient temperatures.

[0078] For example, see Figure 7 In other embodiments, the cooling system 5 includes a compression cooling system 6, which includes a refrigerant pipeline 62, a compression cooling pipeline 61, a compressor 63, a condenser 64, and a heat exchanger 67. The condenser 64 and the compressor 63 are both mounted on the refrigerant pipeline 62, so that the compressor 63 drives the refrigerant to circulate in the refrigerant pipeline 62, and the refrigerant transfers heat to the gas driven by the fan 4 when it flows through the condenser 64. The compression cooling pipeline 61 is thermally coupled to the heat-generating equipment 200 (i.e., heat exchange can be performed), and is connected to different heat exchange channels 68 of the refrigerant pipeline 62 and the heat exchanger 67, so that the cooling liquid in the compression cooling pipeline 61 carries away the heat of the heat-generating equipment 200 and flows through the heat exchanger 67, where it transfers heat to the refrigerant in the refrigerant pipeline 62, thereby cooling the heat-generating equipment 200.

[0079] The aforementioned compression cooling system 6 provides cooling liquid to the heat-generating equipment 200 through compression cooling pipeline 61. The cooling liquid in compression cooling pipeline 61 absorbs heat from the heat-generating equipment 200. Heat exchange between the cooling liquid in compression cooling pipeline 61 and the refrigerant in refrigerant pipeline 62 is achieved through heat exchanger 67. The refrigerant in refrigerant pipeline 62 absorbs the heat absorbed from the heat-generating equipment 200 by the cooling liquid in compression cooling pipeline 61. Driven by compressor 63 on refrigerant pipeline 62, the refrigerant flows through condenser 64 on refrigerant pipeline 62, transferring heat to the gas driven by fan 4 at condenser 64. The gas driven by fan 4 carries away the heat, thereby cooling the heat-generating equipment 200. The cooling process achieved by the compression cooling system 6 can be called the compression cooling process, and the corresponding operating mode can be called the compression cooling mode. In this compression cooling mode, since the cooling liquid does not directly exchange heat with the airflow driven by the fan 4, but rather the refrigerant driven by the compressor 63 exchanges heat with the airflow driven by the fan 4, the cooling and heat dissipation capacity is stronger, and a better cooling effect can be achieved when the ambient temperature is high.

[0080] The aforementioned air-cooling system 7 and pressure-cooling system 6 can be used individually or in combination.

[0081] For example, see Figure 7 In some embodiments, the cooling system 5 includes a pressure cooling system 6 and an air cooling system 7. The pressure cooling pipes 61 of the pressure cooling system 6 and the air cooling pipes 71 of the air cooling system 7 are connected in parallel and thermally coupled to the heat-generating device 200. Based on this, the cooling system 5 can realize both pressure cooling and air cooling modes, providing greater operational flexibility. It can flexibly switch modes according to actual cooling needs to better meet those needs. For example, when the ambient temperature is low, only the air cooling mode can be activated; conversely, when the ambient temperature is high, the pressure cooling mode can be activated. This further enhances the cooling capacity and saves energy, enabling the vehicle-mounted cooling device 101 and the cooling vehicle 100 to achieve better cooling effects with less energy consumption.

[0082] In the case where the cooling system 5 includes a pressure cooling system 6 and an air cooling system 7, the condenser 64 of the pressure cooling system 6 and the surface cooler 72 of the air cooling system 7 can be installed separately or integrated.

[0083] For example, see Figure 5In some embodiments, the condenser 64 of the compression cooling system 6 and the surface cooler 72 of the air-cooled system 7 are respectively part and part of the same heat exchanger 8. In this case, the condenser 64 of the compression cooling system 6 and the surface cooler 72 of the air-cooled system 7 are made into a single unit, integrated on the same heat exchanger 8. Accordingly, part and part of the heat exchanger 8 are respectively constructed as the condenser 64 of the compression cooling system 6 and the surface cooler 72 of the air-cooled system 7. This can effectively save unit space, improve space utilization, and facilitate the rational layout of the positional relationship between the condenser 64 of the compression cooling system 6 and the surface cooler 72 of the air-cooled system 7 and the fan 4, improve the utilization rate of air volume, and achieve full utilization of the fan air field. This allows the fan 4 to play its full role in both compression cooling and air cooling modes, achieving better air cooling and compression cooling effects. This is also conducive to further enhancing the cooling capacity of the vehicle-mounted cooling equipment 101 and the cooling vehicle 100, and reducing the energy consumption of the vehicle-mounted cooling equipment 101 and the cooling vehicle 100.

[0084] As an example of the condenser 64 of the compression cooling system 6 and the surface cooler 72 of the air-cooled system 7 being integrated on the same heat exchanger 8, see [link to relevant documentation]. Figure 5 In some embodiments, the heat exchanger 8 includes a first liquid inlet (not shown), a second liquid inlet (not shown), and multiple rows of heat exchange channels 81. These multiple rows of heat exchange channels 81 are all connected to the first and second liquid inlets, and a portion of these multiple rows of heat exchange channels 81 are configured as condensers 64, while another portion is configured as surface coolers 72. In this case, several rows of heat exchange channels 81 in the heat exchanger 8 are configured as condensers 64 of the compression cooling system 6, while the remaining heat exchange channels 81 are configured as surface coolers 72 of the air-cooled system 7. The condenser 64 and the surface cooler 72 are integrated on the same heat exchanger 8 and share the first and second liquid inlets. The overall structure is simpler and more compact, and it is easier to design the condenser 64 and the surface cooler 72 to achieve better cooling performance.

[0085] For example, to achieve better cooling, see Figure 5 In some embodiments, the number of rows of heat exchange channels 81 corresponding to the condenser 64 is greater than the number of rows of heat exchange channels 81 corresponding to the surface cooler 72. For example, in... Figure 5In this design, the heat exchanger 8 has four rows of heat exchange channels 81. Three of these channels are used as condensers 64, and the remaining channel is used as a surface cooler 72. Specifically, the condenser 64 has three rows of heat exchange channels 81, while the surface cooler 72 has one. This means the number of rows of heat exchange channels 81 corresponding to the condenser 64 is greater than that corresponding to the surface cooler 72. This results in a larger heat exchange area for the condenser 64 compared to the surface cooler 72. This design aligns with the higher cooling requirements of the compression cooling mode corresponding to the condenser 64 and the lower cooling requirements of the air cooling mode corresponding to the surface cooler 72, facilitating better compression and air cooling performance with less energy consumption.

[0086] For example, see Figure 5 In some embodiments, the heat exchange channel 81 corresponding to the surface cooler 72 is located upstream of the heat exchange channel 81 corresponding to the condenser 64 along the direction in which the gas driven by the fan 4 flows out (i.e., in the air outlet direction). Based on this, in the air outlet direction, the surface cooler 72 is located upstream of the condenser 64 and farther from the fan 4 than the condenser 64. Thus, the pressure drop at the surface cooler 72 is smaller, which is more conducive to heat exchange and improves the air cooling effect. This effect is more prominent when the number of rows of heat exchange channels 81 corresponding to the surface cooler 72 is less than the number of rows of heat exchange channels 81 corresponding to the condenser 64. This is because, even with fewer rows of heat exchange channels 81 corresponding to the surface cooler 72, the heat exchange sufficiency at the surface cooler 72 can be improved as much as possible by reducing the pressure drop at the surface cooler 72, so that a good air cooling effect can still be achieved even with fewer rows of heat exchange channels 81 corresponding to the surface cooler 72.

[0087] In the case where the condenser 64 and the surface cooler 72 of the heat dissipation system 3 are integrated into the same heat exchanger 8, see Figure 5 In some embodiments, all the heat dissipation systems 3 of the vehicle-mounted cooling device 101 are divided into two groups. The heat exchangers 8 of these two groups of heat dissipation systems 3 are arranged on opposite sides of the fan 4, and the heat exchangers 8 of the heat dissipation systems 3 located on opposite sides of the fan 4 gradually move away from each other along the direction of the air flow driven by the fan 4. In this way, the multiple heat exchangers 8 of the vehicle-mounted cooling device 101 are arranged on opposite sides of the fan 4, and the distance between the heat exchangers 8 located on opposite sides of the fan 4 gradually increases along the air outlet direction, roughly forming a V-shape. This allows for more efficient use of airflow, and the airflow of the heat exchangers 8 on both sides of the fan 4 is more uniform, resulting in better cooling consistency. This is beneficial for improving the cooling consistency between the various heat dissipation systems 3 and achieving a better cooling effect.

[0088] When the cooling system 5 of the heat dissipation system 3 includes a compression cooling system 6, the number of compressors 63 in the compression cooling system 6 is not limited, and there can be one or more. For example, see Figure 6 and Figure 7 In some embodiments, the compression cooling system 6 includes two compressors 63 connected in parallel. This allows the two compressors 63 to serve as backups for each other, thereby improving the operational reliability of the compression cooling system 6 and facilitating a more efficient and reliable compression cooling process.

[0089] In addition, the compressor 63 of the compression cooling system 6 can be a fixed-frequency or variable-frequency compressor. When the compressor 63 is a variable-frequency compressor, the compressor 63 can be controlled by frequency conversion during operation. In this way, the unit does not need to be repeatedly started and stopped, which can reduce noise, extend life, and also accurately control temperature, effectively save energy, and improve the adaptability of the whole machine to complex operating environments, so that the whole machine can effectively cope with complex operating environments such as different altitudes, temperatures or humidity.

[0090] Furthermore, in various embodiments of this application, the fan 4 can be a fixed-frequency or variable-frequency fan. When the fan 4 is a variable-frequency fan, it can be controlled by frequency conversion during operation. In this way, the unit does not need to be repeatedly started and stopped, which can reduce noise, extend life, and also accurately control temperature, effectively save energy, and improve the adaptability of the whole machine to complex operating environments, so that the whole machine can effectively cope with complex operating environments such as different altitudes, temperatures, or humidity.

[0091] As an example of the outer casing 1 in the foregoing embodiments, see Figures 1-5 In some embodiments, the outer shell 1 includes a back plate 11, a front plate 13, and two side plates 12. The two side plates 12 are connected to opposite ends of the back plate 11, and the front plate 13 is connected between the two side plates 12 and to the back plate 11. The front plate 13 includes a vertically arranged upright plate 14 and an inclined plate 15. The upright plate 14 is connected to the back plate 11 through the inclined plate 15. In this case, the outer shell 1 no longer adopts a traditional cubic shape, but is constructed as an irregular shape with beveled corners. Correspondingly, the irregular shape with beveled corners is less prone to deformation and has stronger vibration and impact resistance. Therefore, it can effectively improve the vibration reduction and vibration resistance of the whole machine. Moreover, by adopting the irregular shape of the outer shell 1 with beveled corners, it can also directly serve as the cabin of the cooling vehicle 100, so that the cooling vehicle 100 no longer needs to include a cabin covering the vehicle-mounted cooling equipment 101. The vehicle-mounted cooling equipment 101 can be directly exposed. This not only helps to simplify the structure and reduce costs, but also facilitates the maintenance of the vehicle-mounted cooling equipment 101 and improves maintenance convenience. Meanwhile, the use of a shell 1 with a beveled, irregular shape can also adapt to special transportation environments such as culverts, making it easier for the cooling vehicle 100 to pass smoothly through transportation channels with special shapes such as culverts, thereby improving the adaptability of the cooling vehicle 100 and the vehicle-mounted cooling equipment 101 to special transportation environments.

[0092] The number of inclined plates 15 is unlimited; there can be one or more. For example, see... Figures 1-5In some embodiments, the front panel 13 includes a plurality of inclined plates 15, which are connected sequentially along the direction from the back panel 11 to the upright panel 14, and have different inclination angles. This helps to further improve the vibration reduction and anti-vibration capabilities of the entire machine, as well as its adaptability to special transportation environments.

[0093] In addition, improving vibration reduction and resistance is not limited to the method of designing the outer shell 1 into an irregular shape with chamfered corners, but other methods can also be used.

[0094] For example, see Figure 6 In some embodiments, the compression cooling system 6 includes not only a compressor 63, but also a clamp 69, which clamps the compressor 63 to reduce its vibration. Since the compressor 63 is a major internal vibration source of the entire machine, the clamp 69 effectively reduces the vibration of the compressor 63, alleviates the vibration of the entire machine, and improves the vibration reduction and anti-vibration performance of the entire machine.

[0095] For example, see Figure 5 In some embodiments, the heat dissipation system 3 includes a vibration damper 41 that clamps the fan 4 to reduce the vibration of the fan 4. Since the fan 4 is another major internal vibration source of the whole machine, the vibration damper 41 clamping the fan 4 can effectively reduce the vibration of the fan 4, reduce the vibration of the whole machine, and improve the vibration reduction and anti-vibration performance of the whole machine.

[0096] For example, in the case where the cooling vehicle 100 includes on-board cooling devices 101 arranged opposite each other along the width direction of the vehicle body 102, in some embodiments, the two on-board cooling devices 101 that are opposite each other along the width direction of the vehicle body 102 are connected to each other. In this way, the two on-board cooling devices 101 that are opposite each other along the width direction of the vehicle body 102 can share the force and resist impact and vibration, thus effectively improving the vibration reduction and anti-vibration performance.

[0097] For example, in the case where the cooling vehicle 100 includes on-board cooling devices 101 arranged along the length of the vehicle body 102, in some embodiments, two adjacent on-board cooling devices 101 along the length of the vehicle body 102 are connected to each other. In this way, two adjacent on-board cooling devices 101 along the length of the vehicle body 102 can share the load and resist impact and vibration, thus effectively improving vibration reduction and anti-vibration performance.

[0098] In the foregoing embodiments, the heat dissipation system 3 of the vehicle-mounted cooling equipment 101 typically operates under the control of the electronic control system 2. The electronic control system 2 is prone to malfunctions and may require frequent maintenance. Therefore, see [link to relevant documentation]. Figure 6In some embodiments, the electronic control system 2 is disposed within the housing 1 and located at the outermost position within the housing 1. Positioning the electronic control system 2 at the outermost position within the housing 1 facilitates its maintenance, thus improving the overall ease of maintenance of the machine.

[0099] Furthermore, in the case where the aforementioned channel 103 is formed between the vehicle-mounted cooling devices 101, see... Figure 1 and Figure 6 The electronic control system 2 of the vehicle-mounted cooling equipment 101 faces and / or is away from the passage 103. In this way, the electronic control system 2 is located in the housing 1 at the position closest to and / or furthest from the passage 103, which makes it convenient for staff to maintain the electronic control system 2 in the passage 103 and / or on the outside of the vehicle body 102 in the width direction, thus improving the ease of maintenance.

[0100] The following will provide further details. Figures 1-7 The example shown.

[0101] like Figures 1-7 As shown, in this embodiment, the cooling vehicle 100 includes a vehicle body 102 and multiple on-board cooling devices 101. These multiple on-board cooling devices 101 are all mounted on the vehicle body 102 and exposed to the outside, without any external shelter or covering, thus facilitating maintenance. Furthermore, these multiple on-board cooling devices 101 are divided into two groups, each group including multiple on-board cooling devices 101 arranged side-by-side along the length of the vehicle body 102, and the two groups of on-board cooling devices 101 are spaced apart along the width of the vehicle body 102, forming a channel 103 between the two groups of on-board cooling devices 101 for convenient maintenance.

[0102] Specifically, by Figure 1 As can be seen, in this embodiment, a total of 6 vehicle-mounted cooling devices 101 are provided on the vehicle body 102. These 6 vehicle-mounted cooling devices 101 are divided into two groups located on both sides of the channel 103, and each group includes 3 vehicle-mounted cooling devices 101 arranged side by side along the length of the vehicle body 102.

[0103] Each vehicle-mounted cooling device 101 is connected to the vehicle body 102. Two vehicle-mounted cooling devices 101 facing each other in the width direction of the vehicle body 102 are interconnected, as are two adjacent vehicle-mounted cooling devices 101 in the length direction of the vehicle body 102. Thus, each vehicle-mounted cooling device 101 is not only connected to the vehicle body 102, but also connected to adjacent vehicle-mounted cooling devices 101, enabling them to collectively resist external vibrations and impacts, thereby effectively improving vibration reduction and anti-vibration performance.

[0104] In this embodiment, the connection between different vehicle-mounted cooling devices 101 is a detachable connection, so that each vehicle-mounted cooling device 101 can be disassembled and installed individually, increasing the convenience of disassembly, assembly and maintenance.

[0105] Each vehicle-mounted cooling device 101 has the same structure, including a housing 1, an electronic control system 2, and two heat dissipation systems 3.

[0106] The housing 1 is used to house the electronic control system 2 and two heat dissipation systems 3. For example... Figures 1-5 As shown, in this embodiment, the outer casing 1 includes a bottom plate 16, a back plate 11, a front plate 13, and two side plates 12. The bottom plate 16 is connected to the vehicle body 102 to connect the vehicle cooling device 101 to the vehicle body 102. The back plate 11, the front plate 13, and the two side plates 12 all extend upward from the bottom plate 16. The back plate 11 is positioned facing the channel 103. The two side plates 12 are connected to the two ends of the front plate 13 along the length direction of the vehicle body (which is also the length direction of the back plate 11 and the outer casing 1). The front plate 13 is connected between the two side plates 12 and is connected to the back plate 11 and the bottom plate 16 to form a chamber within the outer casing 1 together with the back plate 11, the bottom plate 16, and the two side plates 12.

[0107] In this embodiment, the outer shell 1 is integrally welded, that is, the bottom plate 16, the back plate 11, the front plate 13 and the two side plates 12 are connected by welding, which can improve the structural strength of the whole machine and its vibration reduction and anti-vibration performance.

[0108] Furthermore, in this embodiment, the front panel 13 includes a vertical plate 14 and two inclined plates 15. The vertical plate 14 and the back plate 11 are arranged opposite each other along the width direction of the vehicle body 102, and are connected to the bottom plate 16, extending upwards vertically from the bottom plate 16. The two inclined plates 15 are sequentially inclined between the vertical plate 14 and the back plate 11, and the inclination angles of the two inclined plates 15 are not the same. The angle between the inclined plate 15 closer to the back plate 11 and the upward direction is greater than the angle between the inclined plate 15 farther from the back plate 11 and the upward direction. Based on this, in this embodiment, the outer shell 1 has an irregular shape with two chamfered corners, which can effectively improve the vibration reduction and anti-vibration capability of the vehicle-mounted cooling equipment 101, as well as the adaptability of the vehicle-mounted cooling equipment 101 and the cooling vehicle 100 to special transportation environments. Moreover, setting two inclined plates 15 with different inclination angles is also beneficial for realizing the inclined setting of the fan 4 mentioned below, and the V-shaped setting between the two heat exchangers 8.

[0109] Two heat dissipation systems 3 are housed within the outer casing 1 for liquid cooling of the heat-generating equipment 200, thus enabling the on-board cooling equipment 101 to adopt a dual-system design. For example... Figures 1-7As shown, in this embodiment, two heat dissipation systems 3 are thermally coupled to the heat-generating device 200 in parallel, and each includes a fan 4 and a cooling system 5. The cooling system 5 is used to supply cooling liquid to the heat-generating device 200 to absorb the heat of the heat-generating device 200. The fan 4 drives the air inside the casing 1 to flow outward, so that the outward airflow carries away the heat absorbed by the cooling liquid from the heat-generating device 200, thereby achieving liquid cooling of the heat-generating device 200.

[0110] Since both cooling systems 3 include fans 4, in this embodiment, the vehicle-mounted cooling device 101 includes a total of two fans 4. Figures 1-5 As can be seen, in this embodiment, both fans 4 are located at the vents 17 on the outer casing 1. Specifically, the outer casing 1 has two vents 17, which correspond one-to-one with the two fans 4. More specifically, the two vents 17 are located on the inclined plate 15 near the back panel 11 of the outer casing 1, and these two vents 17 are arranged side by side along the length of the vehicle body 102 (which is also the relative arrangement direction of the two side panels 12, or the length direction of the outer casing 1). The two fans 4 are respectively located in the two vents 17, extending into the interior of the outer casing 1 from their respective vents 17 to drive the gas inside the outer casing 1 to flow to the outside of the outer casing 1 for exhaust. In this case, even if only one system of the vehicle cooling equipment 101 is operating, the vent 17 corresponding to the non-operating heat dissipation system 3 can still ventilate, providing airflow to the operating heat dissipation system 3. Therefore, the cooling capacity of each heat dissipation system 3 can be increased, thereby improving the cooling capacity of the vehicle cooling equipment 101.

[0111] The fan 4 is detachably installed at the ventilation opening 17. When maintenance is required, the fan 4 can be lifted out from above.

[0112] Depend on Figure 5 As can be seen, in this embodiment, except for the portion of the fan 4 facing the outside of the outer casing 1, the rest of the fan 4 is held in place by the vibration damping member 41. Specifically, in Figure 5 In the middle, the left and right sides and the bottom of the fan 4 are all clamped by the vibration damping parts 41. In this way, the vibration of the fan 4 can be reduced, the internal vibration of the vehicle cooling equipment 101 can be reduced, the vibration resistance and damping performance of the whole machine can be improved, and the noise of the whole machine can be reduced.

[0113] Furthermore, since both heat dissipation systems 3 include cooling systems 5, in this embodiment, the vehicle-mounted cooling device 101 includes a total of two cooling systems 5. Figures 6-7As shown, in this embodiment, both cooling systems 5 are disposed inside the outer casing 1, and the two cooling systems 5 are connected in parallel and thermally coupled to the heat-generating device 200. This achieves parallel connection between the two heat dissipation systems 3 and thermal coupling with the heat-generating device 200, so that both heat dissipation systems 3 can provide cooling liquid to the heat-generating device 200 through their respective cooling systems 5, and exchange heat with the heat-generating device 200. Thus, one of the two heat dissipation systems 3 can operate selectively to achieve a single-system operation mode, or both heat dissipation systems 3 can operate simultaneously to achieve a dual-system operation mode, thereby improving the operational flexibility of the vehicle-mounted cooling device 101, increasing the cooling capacity of the vehicle-mounted cooling device 101, and expanding the liquid cooling range of the vehicle-mounted cooling device 101.

[0114] In this embodiment, the cooling capacity of a single heat dissipation system 3 is 65 kW. Therefore, the liquid cooling range of the vehicle-mounted cooling device 101 with a dual-system design is 65 kW to 130 kW. Correspondingly, the liquid cooling range of the cooling vehicle 100, which includes six vehicle-mounted cooling devices 101, is 65 kW to 780 kW. It is evident that the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100 is increased, the liquid cooling range is expanded, and they are flexibly adjustable, effectively saving energy.

[0115] In this embodiment, each cooling system 5 has the same structure, including a pressure cooling system 6 and an air cooling system 7 connected in parallel, so as to flexibly switch between the two modes of pressure cooling and air cooling.

[0116] Among them, the compression cooling system 6 is used to achieve the compression cooling mode. Figures 5-7As can be seen, in this embodiment, the compression cooling system 6 includes a compression cooling pipeline 61, a refrigerant pipeline 62, two compressors 63, a condenser 64, a gas-liquid separator 65, an oil separator 66, and a heat exchanger 67. The compression cooling pipeline 61 and the refrigerant pipeline 62 supply refrigerant and cooling liquid for circulation, respectively. The two compressors 63 are connected in parallel and are sequentially arranged on the refrigerant pipeline 62 along with the oil separator 66, the condenser 64, and the gas-liquid separator 65. The condenser 64 is thermally coupled to the fan 4, so that the refrigerant in the refrigerant pipeline 62 can flow sequentially through the oil separator 66, the condenser 64, and the gas-liquid separator 65 under the drive of the compressors 63, and then return to the compressors 63, realizing circulation in the refrigerant pipeline 62. When flowing through the condenser 64, it can exchange heat with the airflow driven by the fan 4. The heat exchanger 67 is specifically a plate heat exchanger, which is located between the condenser 64 and the gas-liquid separator 65. One of its two heat exchange channels 68 is connected to the portion of the refrigerant pipeline 62 located between the condenser 64 and the gas-liquid separator 65, while the other is connected to the pressure cooling pipeline 61. The pressure cooling pipeline 61 is thermally coupled to the heat-generating equipment 200, so that the cooling liquid in the pressure cooling pipeline 61 can circulate between the heat-generating equipment 200 and the heat exchanger 67. The cooling liquid in the pressure cooling pipeline 61 carries away the heat from the heat-generating equipment 200 and flows through the heat exchanger 67, where it transfers heat to the refrigerant in the refrigerant pipeline 62.

[0117] Although not shown in the figure, flow meters, pressure sensors and temperature sensors can be installed on the pressure cooling pipeline 61 to monitor parameters such as flow rate, pressure and temperature of the cooling liquid circulating in the pressure cooling pipeline 61, so as to facilitate adjustment based on the monitoring results and improve the temperature control accuracy of the liquid supply.

[0118] Air-cooling system 7 is used to achieve air-cooling mode. For example... Figure 7 As shown, in this embodiment, the air-cooling system 7 includes an air-cooled pipe 71 and a surface cooler 72. The air-cooled pipe 71 is used to circulate the cooling liquid and is thermally coupled to the heat-generating equipment 200 in parallel with the pressure cooling pipe 61, so as to realize the parallel connection of the air-cooling system 7 and the pressure cooling system 6. The surface cooler 72 is disposed on the air-cooled pipe 71 and is thermally coupled to the fan 4. In this way, the cooling liquid in the air-cooled pipe 71 can carry away the heat of the heat-generating equipment 200 and transfer heat to the gas driven by the fan 4 when flowing through the surface cooler 72, thereby cooling the heat-generating equipment 200.

[0119] Since the cooling system 5 of both heat dissipation systems 3 includes the aforementioned parallel compression cooling system 6 and air cooling system 7, both heat dissipation systems 3 can flexibly switch between compression cooling mode and air cooling mode.

[0120] The air-cooling mode can be activated when the ambient temperature is low. In the corresponding air-cooling mode, only the fan 4 needs to be started, without starting the compressor 63. The cooling liquid circulates in the air-cooling pipe 71. When it flows through the heat-generating equipment 200, it carries away the heat of the heat-generating equipment 200. When it flows through the surface cooler 72, it exchanges heat with the air driven by the fan 4 to achieve the air-cooling process.

[0121] The compression cooling mode can be activated when the ambient temperature is high. In the corresponding compression cooling mode, both the fan 4 and the compressor 63 are started. The cooling liquid circulates in the compression cooling pipeline 61. When it flows through the heat-generating equipment 200, it carries away the heat from the heat-generating equipment 200. When it flows through the heat exchanger 67, it exchanges heat with the refrigerant in the refrigerant pipeline 62. This allows the refrigerant in the refrigerant pipeline 62 to absorb the heat from the heat-generating equipment 200 absorbed by the cooling liquid. Driven by the compressor 63, it flows through the condenser 64, where it exchanges heat with the air driven by the fan 4. The air then carries away the heat, thus realizing the compression cooling process.

[0122] Based on the above configuration, in this embodiment, both heat dissipation systems 3 of the vehicle-mounted cooling equipment 101 have two working modes: air cooling and pressure cooling. Both can freely switch between pressure cooling and air cooling modes within the unit. Furthermore, the pressure cooling and air cooling modes can effectively meet the cooling needs of the heat-generating equipment 200 under different ambient temperatures with less energy consumption. Therefore, this not only further enhances the working flexibility of the vehicle-mounted cooling equipment 101 and improves its cooling capacity, but also saves energy and reduces emissions.

[0123] And, as Figure 5 As shown, in this embodiment, the condenser 64 and surface cooler 72 of each heat dissipation system 3 are integrated onto the same heat exchanger 8, forming a dual-unit system. Specifically, by Figure 5 As can be seen, in this embodiment, the two heat exchangers 8 corresponding to the two heat dissipation systems 3 are arranged on both sides of the fan 4 along the relative arrangement direction of the back plate 11 and the upright plate 14 (which is also the width direction of the vehicle body 102, or the width direction of the outer shell 1), and each heat exchanger 8 includes four rows of heat exchange channels 81, which are arranged along the air outlet direction (in the direction of airflow). Figure 5The heat exchange channels 81 (also along the thickness direction of the heat exchangers 8) are arranged side by side. The row of heat exchange channels 81 furthest from the fan 4 serves as the surface cooler 72, while the other three rows of heat exchange channels 81 serve as the condenser 64. The condenser 64 and the surface cooler 72 share two liquid inlets. This design makes the structure simpler and more compact, effectively reducing space occupation and improving space utilization. It also allows the fan 4 to be closer to the two heat exchangers, improving the utilization rate of airflow. This enables both air-cooling and compression-cooling modes to fully utilize the fan's airflow field, achieving better air-cooling and compression-cooling effects. In particular, since the surface cooler 72 is located upstream of the condenser 64 along the air outlet direction, its pressure drop is smaller, resulting in more efficient heat exchange. This allows for better air-cooling performance even with fewer rows of heat exchange channels 81 corresponding to the surface cooler 72.

[0124] Moreover, by Figure 5 As can be seen, in this embodiment, the fan 4 is inclined, with its longitudinal central axis perpendicular to the thickness direction of the inclined plate 15 closer to the back plate 11, forming an angle with the horizontal plane. Of the two heat exchangers 8 located on either side of the fan 4, one heat exchanger 8 is arranged vertically, while the other heat exchanger 8 is connected at one end to the inclined plate 15 farther from the back plate 11, and the other end is inclined downwards. This causes the distance between the two heat exchangers 8 on either side of the fan 4 to gradually increase along the airflow direction (or from bottom to top), roughly forming a V-shape. This helps to make the airflow of the two heat exchangers 3 approximately similar, improving the consistency of cooling in both systems.

[0125] In this embodiment, all four compressors 63 are variable frequency compressors, and both fans 44 are variable frequency fans. These four compressors 63 and two fans 4 are controlled by six drive boards (located in the electrical box) to prevent repeated start-stop, reduce noise, extend life, accurately control temperature, effectively save energy, and improve the adaptability of the whole machine to complex operating environments.

[0126] like Figure 6 As shown, in this embodiment, the two sets of compressors 63, condensers 64, gas-liquid separators 65, oil separators 66, and heat exchangers 67 corresponding to the two heat dissipation systems 3 are arranged side-by-side along the length of the vehicle body 102 within the outer casing 1, and are symmetrically positioned about the middle of the length of the outer casing 1. Furthermore, the two sets of compressors 63, condensers 64, gas-liquid separators 65, oil separators 66, and heat exchangers 67 corresponding to the two heat dissipation systems 3 are located on the side of the cooling pipe 61 near the back plate 11 (also near the channel 103) within the outer casing 1. Thus, the overall layout is compact and reasonable.

[0127] Furthermore, by Figure 6 As can be seen, in this embodiment, the electronic control system 2 of the vehicle-mounted cooling device 101 is located on the outermost side in the width direction within the housing 1. Specifically, as... Figure 6As shown, in this embodiment, the electronic control system 2 includes a first electronic control device 21 and a second electronic control device 22. The first electronic control device 21 is located in the housing 1 on the side of the two sets of compressors 63, condensers 64, gas-liquid separators 65, oil separators 66, and heat exchangers 67 near the back plate 11, adjacent to the back plate 11 and facing the channel 103. The second electronic control device 22 is located in the housing 1 on the side of the two sets of compression cooling pipes 61 and the two sets of compressors 63, condensers 64, gas-liquid separators 65, oil separators 66, and heat exchangers 67 near the front plate 13, adjacent to the front plate 13 and away from the channel 103. Thus, the first electronic control device 21 and the second electronic control device 22 are located in the housing 1 on the side closest to the back plate 11 and the side furthest from the back plate 11, respectively. The entire electronic control system 2 is located on the outermost side in the width direction in the housing 1, either closest to the channel 103 or closest to the outermost side in the width direction of the vehicle body, which facilitates maintenance. During maintenance, the electronic control system 2 can be repaired from the side of the vehicle and in the passage 103, which is simple and convenient.

[0128] In addition, in this embodiment, the pipes and other components of each heat dissipation system 3 that are connected to the heat generation equipment 200 are also arranged in the channel 103 for easy maintenance.

[0129] Moreover, such as Figure 6 As shown, in this embodiment, the compressor 63 of each heat dissipation system 3, except for the foot pad 6a, is entirely clamped by clamps 69, which are then supported and fixed by brackets 60. This reduces the vibration of the compressor 63, alleviates the internal vibration of the vehicle-mounted cooling equipment 101, improves the vibration damping and anti-vibration performance of the vehicle-mounted cooling equipment 101 and the cooling vehicle 100, and reduces noise.

[0130] As can be seen, in this embodiment, the vehicle-mounted cooling device 101 is a vehicle-mounted cooling device with good vibration resistance, large cooling capacity, small weight, and easy maintenance. It adopts a double-beveled shape and uses dual-system dual-mode frequency conversion control, which can make full use of vehicle space, achieve frequency conversion, modularization, lightweighting, vibration reduction and noise reduction, easy maintenance, and realize a large cooling capacity, a large liquid cooling range, precise temperature control, and energy-efficient cooling process, which can effectively improve the performance of the cooling vehicle 100.

[0131] The above description is merely an exemplary embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
