[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0054] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0055] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description.

[0056] In the description of the present application, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0057] In the present application, unless otherwise specified, “plurality” means at least two, that is, including cases of two and at least three.

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

[0059] In order to better meet the cooling demand, the present application improves the structure of a vehicle-mounted cooling device and provides a vehicle-mounted cooling device and a cooling vehicle.

[0060] Figures 1 - 7 The cooling vehicle and the vehicle-mounted cooling device thereof in the present application are shown exemplarily.

[0061] in, Figure 1 Shows part of the cooling car structure. Figure 1, in the present application, the cooling vehicle 100 includes a vehicle body 102 and on-vehicle cooling equipment 101. The vehicle body 102 generally includes a traveling mechanism (not shown in the figure) to enable the whole vehicle to travel, so that the cooling vehicle 100 can flexibly move to different positions to cool different heat-generating devices 200 (see Figure 7 ). The on-vehicle cooling equipment 101 is disposed on the vehicle body 102 and is used to transport cooling liquid to the heat-generating device 200, so that the heat of the heat-generating device 200 can be taken away by the cooling liquid to achieve cooling and heat dissipation of the heat-generating device 200.

[0062] As Figure 1 can be seen, in some embodiments, the cooling vehicle 100 includes more than one on-vehicle cooling equipment 101, but a plurality of on-vehicle cooling equipment 101. These plurality of on-vehicle cooling equipment 101 are all disposed on the vehicle body 102 and are arranged along the length and / or width direction of the vehicle body 102. In this way, the number of on-vehicle cooling equipment 101 is large, and a greater cooling capacity can be provided. Therefore, the cooling vehicle 100 has a strong cooling ability. It can be understood that the length direction and width direction of the vehicle body 102 are also the front-back direction and left-right direction of the cooling vehicle 100.

[0063] As an example of the cooling vehicle 100 including a plurality of on-vehicle cooling equipment 101, see Figure 1 , in some embodiments, the cooling vehicle 100 includes two groups of on-vehicle cooling equipment 101. These two groups of on-vehicle cooling equipment 101 both include at least one on-vehicle cooling equipment 101, and these two groups of on-vehicle cooling equipment 101 are arranged at intervals along the width direction of the vehicle body 102, so that a channel 103 is formed between the two groups of on-vehicle cooling equipment 101. Since the channel 103 can be used for staff to pass through and repair the on-vehicle cooling equipment 101, the vehicle repair convenience can be improved.

[0064] Among them, the number of on-vehicle cooling equipment 101 in each group of on-vehicle cooling equipment 101 is not limited and can be one or more. For example, see Figure 1 , in some embodiments, both groups of on-vehicle cooling equipment 101 include a plurality of on-vehicle cooling equipment 101, and the plurality of on-vehicle cooling equipment 101 in the same group of on-vehicle cooling equipment 101 are arranged side by side along the length direction of the vehicle body 102. In this way, the number of on-vehicle cooling equipment 101 on the cooling vehicle 100 is more, and the cooling ability of the cooling vehicle 100 can be further improved.

[0065] Figures 2 - 7 Further shows the structure and working principle of the on-vehicle cooling equipment 101.

[0066] See Figures 2 - 7, in the present application, the vehicle-mounted cooling device 101 includes a housing 1 and a plurality of heat dissipation systems 3. Among them, a plurality of ventilation openings 17 are provided on the housing 1. Each of the plurality of heat dissipation systems 3 includes a fan 4 and a cooling system 5. The fans 4 of the plurality of heat dissipation systems 3 are respectively arranged at the plurality of ventilation openings 17 to drive the gas in the housing 1 to flow out from the plurality of ventilation openings 17. The cooling systems 5 of the plurality of heat dissipation systems 3 are all arranged in the housing 1 and are connected in parallel with each other to provide a cooling liquid for the heat generating device 200, so as to absorb the heat of the heat generating device 200 and enable the absorbed heat to be carried away by the gas driven by the fan 4, thereby realizing the cooling of the heat generating device 200.

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

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

[0069] However, the above solution breaks through the traditional design concept of the vehicle-mounted cooling device 101 adopting a single-system design. Breakthroughly, the vehicle-mounted cooling device 101 is designed to adopt a multi-system design, so that the vehicle-mounted cooling device 101 no longer only includes one heat dissipation system 3, but includes a plurality of heat dissipation systems 3 connected in parallel with each other. In this way, the vehicle-mounted cooling device 101 no longer can only rely on a single heat dissipation system 3 to cool and dissipate the heat of the heat generating device 200, but can, according to actual needs, flexibly rely on one or more heat dissipation systems 3 to cool and dissipate the heat of the heat generating device 200. That is to say, it can flexibly operate in a single-system or multi-system mode. For example, if the cooling requirement is high, at least two of the plurality of heat dissipation systems 3 can be made to work to provide a large cooling capacity and effectively meet the corresponding higher cooling requirements. If the cooling requirement is low, only one of the plurality of heat dissipation systems 3 can be made to work to provide a small cooling capacity and effectively meet the corresponding lower cooling requirements. In this way, the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100 can be increased, and the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100 can be adjusted, effectively expanding the liquid cooling range of the vehicle-mounted cooling device 101 and the cooling vehicle 100, thereby effectively enhancing the cooling ability of the vehicle-mounted cooling device 101 and the cooling vehicle 100.

[0070] Here, a case where the cooling capacity (or heat dissipation amount) of a cooling system 3 is 65 kw is taken as an example for illustration. If the cooling capacity of a cooling system 3 is 65 kw, then, the vehicle-mounted cooling device 101 adopting a dual-system design (i.e., having two parallel cooling systems 3) can flexibly switch the cooling capacity between 65 and 130 kw, and the cooling vehicle 100 having 6 vehicle-mounted cooling devices 101 can flexibly switch the cooling capacity between 65 and 780 kw. Therefore, the cooling capacity is larger and adjustable, the liquid cooling range is wider, and the cooling ability is stronger.

[0071] The above vehicle-mounted cooling device 101 having multiple cooling systems 3 not only has a stronger cooling ability compared with a single vehicle-mounted cooling device 101 that only includes a single cooling system 3, but also has a stronger cooling ability compared with the same number of vehicle-mounted cooling devices 101 that only include a single cooling system 3. Because, for the vehicle-mounted cooling device 101 having multiple cooling systems 3, when only some of the cooling systems 3 are working, the ventilation openings 17 corresponding to the other cooling systems 3 can also ventilate, providing air volume for the working cooling systems 3. The ventilation area is larger, the heat dissipation amount is more, and the cooling ability is stronger. While for the same number of vehicle-mounted cooling devices 101 that only include a single cooling system 3, when some of the vehicle-mounted cooling devices 101 are working, the ventilation openings 17 of the other vehicle-mounted cooling devices 101 do not provide air volume for the working vehicle-mounted cooling devices 101. The ventilation area is smaller, the heat dissipation amount is less, and the cooling ability is weaker. From another perspective, for a vehicle-mounted cooling device 101 that only includes a single cooling system 3, if the same heat dissipation amount is to be achieved, a larger area needs to be occupied, resulting in that the same number of vehicle-mounted cooling devices 101 cannot be arranged on the cooling vehicle 100. For example, in Figure 1 when the vehicle-mounted cooling device 101 adopts a dual-system design, 6 vehicle-mounted cooling devices 101 can be arranged on the vehicle body 102. However, if the vehicle-mounted cooling device 101 adopts a single-system design with the same heat dissipation amount, the vehicle-mounted cooling device 101 needs to occupy a larger area, resulting in that 6 vehicle-mounted cooling devices 101 cannot be arranged on the vehicle body 102 anymore, and the number of vehicle-mounted cooling devices 101 becomes smaller. Therefore, the cooling capacity is smaller, the liquid cooling range is narrower, and the cooling ability is weaker.

[0072] It can be seen that by setting the vehicle-mounted cooling device 101 to include multiple parallel cooling systems 3, the vehicle-mounted cooling device 101 can be flexibly switched between a single-system operation mode and a 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, and expanding the liquid cooling range of the vehicle-mounted cooling device 101 and the cooling vehicle 100. Therefore, the cooling ability of the vehicle-mounted cooling device 101 and the cooling vehicle 100 can be effectively enhanced, better meeting the cooling requirements.

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

[0074] It can be seen that by setting the vehicle-mounted cooling device 101 to include a plurality of parallel heat dissipation systems 3, the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100 can be stronger and more energy-saving.

[0075] The heat dissipation system 3 provides cooling liquid for the heat-generating device 200 through the cooling system 5. Among them, the cooling system 5 can adopt various structural forms.

[0076] For example, referring to Figure 7 , in some embodiments, the cooling system 5 includes an air-cooling system 7. The air-cooling system 7 includes an air-cooling pipeline 71 and a surface cooler 72. The air-cooling pipeline 71 is thermally coupled to the heat-generating device 200, and the surface cooler 72 is arranged on the air-cooling pipeline 71, so that the cooling liquid in the air-cooling pipeline 71 takes away the heat of the heat-generating device 200 and transfers heat to the gas driven by the fan 4 when flowing through the surface cooler 72, realizing the cooling of the heat-generating device 200.

[0077] The above air-cooling system 7 can provide cooling liquid for the heat-generating device 200 through the air-cooling pipeline 71, and use the cooling liquid in the air-cooling pipeline 71 to absorb the heat of the heat-generating device 200. The cooled liquid after heat absorption can flow through the surface cooler 72 on the air-cooling pipeline 71 and transfer heat to the gas driven by the fan 4 at the surface cooler 72, and the gas driven by the fan 4 takes away the heat, thus realizing the cooling of the heat-generating device 200. The cooling process realized by the corresponding air-cooling system 7 can be called the air-cooling process, and the corresponding working mode can be called the air-cooling mode. This air-cooling mode can especially effectively meet the cooling requirements in the case of a relatively low ambient temperature, enabling the cooling system 5 to achieve a better cooling effect in the case of a relatively low ambient temperature.

[0078] For another example, referring to Figure 7 , in some other embodiments, the cooling system 5 includes a compression-cooling system 6. The compression-cooling system 6 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 arranged 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 flowing through the condenser 64. The compression-cooling pipeline 61 is thermally coupled to the heat-generating device 200 (i.e., heat exchange can be carried out), 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 takes away the heat of the heat-generating device 200 and then flows through the heat exchanger 67, and transfers heat to the refrigerant in the refrigerant pipeline 62 at the heat exchanger 67, realizing the cooling of the heat-generating device 200.

[0079] The above-mentioned pressure-cooling system 6 can supply cooling liquid to the heat-generating device 200 through the pressure-cooling pipeline 61. The cooling liquid in the pressure-cooling pipeline 61 absorbs the heat of the heat-generating device 200, and the heat exchange between the cooling liquid in the pressure-cooling pipeline 61 and the refrigerant in the refrigerant pipeline 62 can be realized through the heat exchanger 67. The refrigerant in the refrigerant pipeline 62 absorbs the heat that the cooling liquid in the pressure-cooling pipeline 61 absorbs from the heat-generating device 200. The refrigerant after absorbing heat can flow through the condenser 64 on the refrigerant pipeline 62 under the drive of the compressor 63 on the refrigerant pipeline 62, and transfer heat to the gas driven by the fan 4 at the condenser 64. The gas driven by the fan 4 takes away the heat, thereby realizing the cooling of the heat-generating device 200. The cooling process realized by the corresponding pressure-cooling system 6 can be called the pressure-cooling process, and the corresponding working mode can be called the pressure-cooling mode. In this pressure-cooling mode, since the cooling liquid does not directly exchange heat with the air flow driven by the fan 4, but exchanges heat with the air flow driven by the fan 4 through the refrigerant driven by the compressor 63, the cooling and heat dissipation ability is stronger, and a better cooling effect can be achieved when the ambient temperature is relatively high.

[0080] The above-mentioned air-cooling system 7 and pressure-cooling system 6 can be used separately or in combination.

[0081] For example, referring to Figure 7 , in some embodiments, the cooling system 5 includes a pressure-cooling system 6 and an air-cooling system 7. The pressure-cooling pipeline 61 of the pressure-cooling system 6 and the air-cooling pipeline 71 of the air-cooling system 7 are thermally coupled to the heat-generating device 200 in parallel with each other. Based on this, the cooling system 5 can realize two heat dissipation modes of pressure-cooling and air-cooling, with higher working flexibility. It can flexibly switch modes according to actual cooling requirements to better meet the cooling needs. For example, the air-cooling mode can be enabled only when the ambient temperature is relatively low. For another example, the pressure-cooling mode can be enabled when the ambient temperature is relatively high. In this way, the cooling capacity can be further enhanced and energy can be saved further, enabling the vehicle-mounted cooling device 101 and the cooling vehicle 100 to achieve a better cooling effect based on less energy consumption.

[0082] When 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 set separately or integrally.

[0083] For example, referring to Figure 5, in some embodiments, the condenser 64 of the compression refrigeration system 6 and the surface cooler 72 of the air-cooling system 7 are respectively a part and another part of the same heat exchanger 8. At this time, the condenser 64 of the compression refrigeration system 6 and the surface cooler 72 of the air-cooling system 7 are made into a two-in-one device, and the two are integrated on the same heat exchanger 8. A part and another part of the corresponding heat exchanger 8 are respectively configured as the condenser 64 of the compression refrigeration system 6 and the surface cooler 72 of the air-cooling system 7. In this way, the space of the unit can be effectively saved, the space utilization rate can be improved, and moreover, it is convenient to reasonably arrange the positional relationship between the condenser 64 of the compression refrigeration system 6 and the surface cooler 72 of the air-cooling system 7 and the fan 4, improve the utilization rate of the air volume, and realize the full utilization of the fan air field, so that the fan 4 can fully play its role in both the compression refrigeration and air-cooling modes, achieving better air-cooling and compression refrigeration effects. This is also beneficial to further enhancing the cooling capacity of the vehicle-mounted cooling device 101 and the cooling vehicle 100, and reducing the energy consumption of the vehicle-mounted cooling device 101 and the cooling vehicle 100.

[0084] As an example of integrating the condenser 64 of the compression refrigeration system 6 and the surface cooler 72 of the air-cooling system 7 on the same heat exchanger 8, refer to Figure 5 , in some embodiments, the heat exchanger 8 includes a first liquid passage port (not shown), a second liquid passage port (not shown), and multiple rows of heat exchange channels 81. All these multiple rows of heat exchange channels 81 are communicated with the first liquid passage port and the second liquid passage port, and a part of these multiple rows of heat exchange channels 81 is configured as the condenser 64, and another part is configured as the surface cooler 72. In this case, several rows of the multiple rows of heat exchange channels 81 of the heat exchanger 8 are configured as the condenser 64 of the compression refrigeration system 6, and the remaining heat exchange channels 81 are configured as the surface cooler 72 of the air-cooling system 7. The condenser 64 and the surface cooler 72 are integrated on the same heat exchanger 8 and share the first liquid passage port and the second liquid passage port. The overall structure is simpler and more compact, and it is more convenient to design the condenser 64 and the surface cooler 72 to achieve better cooling effects.

[0085] For example, in order to achieve better cooling effects, refer to Figure 5 , in some embodiments, the number of rows of the heat exchange channels 81 corresponding to the condenser 64 is greater than the number of rows of the heat exchange channels 81 corresponding to the surface cooler 72. Exemplarily, in Figure 5In this case, the heat exchanger 8 has a total of 4 rows of heat exchange channels 81. Among these 4 rows of heat exchange channels 81, 3 rows of heat exchange channels 81 are used as the condenser 64, and the remaining 1 row of heat exchange channels 81 is used as the surface cooler 72. That is to say, the number of rows of heat exchange channels 81 corresponding to the condenser 64 is 3, and the number of rows of heat exchange channels 81 corresponding to the surface cooler 72 is 1. 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. In this way, the heat exchange area of the condenser 64 is larger than that of the surface cooler 72, which is adapted to the characteristics that the cooling requirement of the compression cooling mode corresponding to the condenser 64 is higher and the cooling requirement of the air cooling mode corresponding to the surface cooler 72 is lower, and is beneficial to achieving better compression cooling and air cooling effects based on less energy consumption.

[0086] For another example, refer to Figure 5 , in some embodiments, the heat exchange channels 81 corresponding to the surface cooler 72 are located upstream of the heat exchange channels 81 corresponding to the condenser 64 along the direction in which the gas is driven out by the fan 4 (i.e., the air outlet direction). Based on this, in the air outlet direction, the surface cooler 72 is located upstream of the condenser 64 and is farther from the fan 4 than the condenser 64. In this way, the pressure drop at the surface cooler 72 is smaller, which is more conducive to heat exchange and is beneficial to improving 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. Because, when the number of rows of heat exchange channels 81 corresponding to the surface cooler 72 is small, by reducing the pressure drop at the surface cooler 72, the heat exchange adequacy at the surface cooler 72 can be improved as much as possible, so that a better air cooling effect can be achieved even when the number of rows of heat exchange channels 81 corresponding to the surface cooler 72 is small.

[0087] When the condenser 64 and the surface cooler 72 of the heat dissipation system 3 are integrated into the same heat exchanger 8, refer to 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 are gradually separated from each other along the direction in which the gas is driven out 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, generally in a V shape. In this way, the air volume can be utilized more fully, and the air volume of the heat exchangers 8 on both sides of the fan 4 is more evenly distributed, and the refrigeration consistency is better, which is beneficial to improving the refrigeration consistency between the 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 can be one or more. For example, refer toFigure 6 and Figure 7 In some embodiments, the compression refrigeration system 6 includes two compressors 63, and the two compressors 63 are connected in parallel. In this way, the two compressors 63 can be used as backups for each other, thereby improving the working reliability of the compression refrigeration system 6, which is beneficial to achieving a more efficient and reliable compression refrigeration process.

[0089] In addition, the compressor 63 of the compression refrigeration system 6 can be a fixed-frequency or variable-frequency compressor. When the compressor 63 is a variable-frequency compressor, during the working process, the compressor 63 can be controlled with variable frequency. In this way, the unit does not need to start and stop repeatedly, which can reduce noise, extend the service life, and moreover, can accurately control the temperature, effectively save energy, improve the adaptability of the whole machine to complex usage environments, and enable the whole machine to effectively respond to complex usage environments such as different altitudes, temperatures, or humidities.

[0090] In addition, in the embodiments of the present application, the fan 4 can be a fixed-frequency or variable-frequency fan. When the fan 4 is a variable-frequency fan, during the working process, the fan 4 can be controlled with variable frequency. In this way, the unit does not need to start and stop repeatedly, which can reduce noise, extend the service life, and moreover, can accurately control the temperature, effectively save energy, improve the adaptability of the whole machine to complex usage environments, and enable the whole machine to effectively respond to complex usage environments such as different altitudes, temperatures, or humidities.

[0091] As an example of the housing 1 in the foregoing embodiments, refer to Figures 1 - 5 , in some embodiments, the housing 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. The front plate 13 is connected between the two side plates 12 and is connected to the back plate 11. The front plate 13 includes a vertical plate 14 and an inclined plate 15 arranged obliquely. The vertical plate 14 is connected to the back plate 11 through the inclined plate 15. At this time, the housing 1 no longer adopts the traditional cubic shape, but is constructed into a special-shaped shape with chamfers. Correspondingly, the special-shaped shape with chamfers is less likely to deform and has stronger anti-vibration and anti-impact capabilities. Therefore, the vibration damping and anti-vibration capabilities of the whole machine can be effectively improved. Moreover, by using the housing 1 with a special-shaped shape with chamfers, it can directly serve as the cabin of the cooling vehicle 100, so that the cooling vehicle 100 can no longer include a cabin covering the outside of the vehicle-mounted cooling device 101, and the vehicle-mounted cooling device 101 can be directly exposed. In this way, it is not only beneficial to simplify the structure and reduce costs, but also convenient for the maintenance of the vehicle-mounted cooling device 101 and improves the maintenance convenience. At the same time, by using the housing 1 with a special-shaped shape with chamfers, it can also adapt to special transportation environments such as culverts, and facilitate the cooling vehicle 100 to smoothly pass through transportation channels with special shapes such as culverts, improving the adaptability of the cooling vehicle 100 and the vehicle-mounted cooling device 101 to special transportation environments.

[0092] Among them, the number of the inclined plates 15 is not limited and can be one or more. For example, refer to Figures 1 - 5, in some embodiments, the front panel 13 includes a plurality of inclined plates 15, which are sequentially connected along the direction from the back panel 11 to the vertical plate 14 and have different inclination angles. This is conducive to further improving the vibration damping and anti-vibration capabilities of the whole machine, as well as the adaptability to special transportation environments.

[0093] In addition, improving the vibration damping and anti-vibration capabilities is not limited to adopting the above-mentioned means of designing the housing 1 into a special-shaped shape with chamfering, but other means can also be adopted.

[0094] For example, referring to Figure 6 , in some embodiments, the compression refrigeration system 6 not only includes a compressor 63, but also includes a clamp 69 that clamps the compressor 63 to reduce the vibration of the compressor 63. Since the compressor 63 is a main internal vibration source of the whole machine, setting the clamp 69 to clamp the compressor 63 can effectively reduce the vibration of the compressor 63, reduce the vibration of the whole machine, and improve the vibration damping and anti-vibration performance of the whole machine.

[0095] For another example, referring to Figure 5 , in some embodiments, the heat dissipation system 3 includes a vibration damping member 41 that clamps the fan 4 to reduce the vibration of the fan 4. Since the fan 4 is another main internal vibration source of the whole machine, setting the vibration damping member 41 to clamp the fan 4 can effectively reduce the vibration of the fan 4, reduce the vibration of the whole machine, and improve the vibration damping and anti-vibration performance of the whole machine.

[0096] For yet another example, in the case where the cooling vehicle 100 includes vehicle-mounted cooling devices 101 arranged opposite to each other along the width direction of the vehicle body 102, in some embodiments, two vehicle-mounted cooling devices 101 opposite to each other along the width direction of the vehicle body 102 are connected to each other. In this way, the two vehicle-mounted cooling devices 101 opposite to each other along the width direction of the vehicle body 102 can jointly bear the force and resist impact and vibration. Therefore, the vibration damping and anti-vibration performance can be effectively improved.

[0097] For another example, in the case where the cooling vehicle 100 includes vehicle-mounted cooling devices 101 arranged along the length direction of the vehicle body 102, in some embodiments, two adjacent vehicle-mounted cooling devices 101 along the length direction of the vehicle body 102 are connected to each other. In this way, the two adjacent vehicle-mounted cooling devices 101 along the length direction of the vehicle body 102 can jointly bear the force and resist impact and vibration. Therefore, the vibration damping and anti-vibration performance can be effectively improved.

[0098] In the foregoing embodiments, the heat dissipation system 3 of the vehicle-mounted cooling device 101 and the like generally operate under the control of the electric control system 2. The electric control system 2 is prone to problems and may need to be frequently repaired. In view of this, referring to Figure 6, in some embodiments, the electronic control system 2 is disposed in the housing 1 and is located at the outermost position in the housing 1. Disposing the electronic control system 2 at the outermost position in the housing 1 makes it more convenient to repair the electronic control system 2. Therefore, it is beneficial to improve the convenience of overall machine repair.

[0099] Further, in the case where the aforementioned channel 103 is formed between the vehicle-mounted cooling devices 101, refer to Figure 1 and Figure 6 , the electronic control system 2 of the vehicle-mounted cooling device 101 faces and / or deviates from the channel 103. In this way, the electronic control system 2 is located at the position closest to and / or farthest from the channel 103 in the housing 1, facilitating maintenance of the electronic control system 2 by the staff in the channel 103 and / or on the outer side in the width direction of the vehicle body 102. Therefore, it is also beneficial to improve the convenience of maintenance.

[0100] Next, further introduce the Figures 1 - 7 illustrated embodiment.

[0101] As Figures 1 - 7 shown, in this embodiment, the cooling vehicle 100 includes a vehicle body 102 and a plurality of vehicle-mounted cooling devices 101. These plurality of vehicle-mounted cooling devices 101 are all disposed on the vehicle body 102 and are exposed outside, without a shelter provided outside and not covered by a shelter. Therefore, it is convenient for maintenance. Moreover, these plurality of vehicle-mounted cooling devices 101 are divided into two groups, and each group of vehicle-mounted cooling devices 101 includes a plurality of vehicle-mounted cooling devices 101 arranged side by side along the length direction of the vehicle body 102, and the two groups of vehicle-mounted cooling devices 101 are spaced apart along the width direction of the vehicle body 102, so as to form a channel 103 between the two groups of vehicle-mounted cooling devices 101 for convenient maintenance.

[0102] Specifically, as Figure 1 known, 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 direction of the vehicle body 102.

[0103] Each vehicle-mounted cooling device 101 is connected to the vehicle body 102, and two vehicle-mounted cooling devices 101 opposite to each other in the width direction of the vehicle body 102 are connected to each other. At the same time, two adjacent vehicle-mounted cooling devices 101 in the length direction of the vehicle body 102 are connected to each other. In this way, each vehicle-mounted cooling device 101 is not only connected to the vehicle body 102, but also connected to the relatively adjacent vehicle-mounted cooling devices 101, and can jointly resist external vibration and impact, thereby effectively improving the vibration damping and anti-vibration performance.

[0104] In this embodiment, the connection between different vehicle-mounted cooling devices 101 is a detachable connection, so as to disassemble and assemble each vehicle-mounted cooling device 101 separately, increasing the convenience of disassembly, assembly and maintenance.

[0105] Among them, the structure of each vehicle-mounted cooling device 101 is the same, and each includes a housing 1, an electric control system 2 and two heat dissipation systems 3.

[0106] The housing 1 is used to accommodate the electric control system 2 and the two heat dissipation systems 3. As Figures 1 - 5 shown, in this embodiment, the housing 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 realize the connection between the vehicle-mounted cooling device 101 and 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. Among them, the back plate 11 faces the channel 103. The two side plates 12 are connected to both 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 housing 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 enclose a chamber inside the housing 1 together with the back plate 11, the bottom plate 16 and the two side plates 12.

[0107] In this embodiment, the housing 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 the vibration damping and anti-vibration performance.

[0108] Moreover, in this embodiment, the front plate 13 includes a vertical plate 14 and two inclined plates 15. Among them, the vertical plate 14 and the back plate 11 are arranged opposite to each other along the width direction of the vehicle body 102, and it is connected to the bottom plate 16 and extends upward along the vertical direction from the bottom plate 16; while the two inclined plates 15 are sequentially and obliquely connected between the vertical plate 14 and the back plate 11, and the inclination angles of the two inclined plates 15 are not the same, but the included angle between the inclined plate 15 close to the back plate 11 and the upward direction is greater than the included angle between the inclined plate 15 far from the back plate 11 and the upward direction. Based on this, in this embodiment, the housing 1 has a special-shaped shape with two chamfers, which can effectively improve the vibration damping and anti-vibration ability of the vehicle-mounted cooling device 101, as well as the adaptability of the vehicle-mounted cooling device 101 and the cooling vehicle 100 to the special transportation environment. Moreover, setting two inclined plates 15 with different inclination angles is also beneficial to realize the inclined setting of the fan 4 mentioned below and the V-shaped setting between the two heat exchangers 8.

[0109] The two heat dissipation systems 3 are arranged in the housing 1 and are used for liquid cooling of the heat generating device 200, so that the vehicle-mounted cooling device 101 adopts a dual-system design. As 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 deliver cooling liquid to the heat generating device 200, so as to absorb the heat of the heat generating device 200 by using the cooling liquid. The fan 4 drives the air in the housing 1 to flow outward, so that the heat of the heat generating device 200 absorbed by the cooling liquid is taken away by the outward flowing airflow, thereby realizing liquid cooling of the heat generating device 200.

[0110] Since both cooling systems 3 include fans 4, in this embodiment, the vehicle cooling device 101 includes two fans 4 in total. Figures 1 - 5 It can be seen that in this embodiment, the two fans 4 are both arranged at the vents 17 on the housing 1. Specifically, the housing 1 is provided with two vents 17, and the two vents 17 correspond to the two fans 4 one by one. More specifically, the two vents 17 are arranged on the inclined plate 15 of the housing 1 close to the back plate 11, and the two vents 17 are arranged side by side along the length direction of the vehicle body 102 (which is also the relative arrangement direction of the two side plates 12, or the length direction of the housing 1), and the two fans 4 are respectively arranged in the two vents 17, and extend from the corresponding vents 17 to the inside of the housing 1 to drive the gas in the housing 1 to flow to the outside of the housing 1 for air discharge. In this case, even if only a single system of the vehicle cooling device 101 is operated, the vents 17 corresponding to the other non-operating heat dissipation system 3 can also be ventilated to provide air volume for the operating heat dissipation system 3, thereby increasing the cooling capacity of each heat dissipation system 3 and improving the cooling capacity of the vehicle cooling device 101.

[0111] The fan 4 is detachably arranged at the vent 17 , and when maintenance is required, the fan 4 can be lifted out from above.

[0112] Depend on Figure 5 It can be seen that in this embodiment, except for the part of the fan 4 facing the outside of the housing 1, the rest of the fan 4 is clamped by the vibration damping member 41. Specifically, Figure 5 In the embodiment, the left and right sides and the lower side of the fan 4 are clamped by the vibration damping member 41, so that the vibration of the fan 4 can be reduced, the internal vibration of the vehicle-mounted cooling device 101 can be reduced, the vibration resistance and vibration reduction performance of the whole machine can be improved, and the noise of the whole machine can be reduced.

[0113] In addition, since both heat dissipation systems 3 include a cooling system 5, in this embodiment, the vehicle-mounted cooling device 101 includes two cooling systems 5 in total. Figures 6 - 7As shown, in this embodiment, two cooling systems 5 are both disposed inside the housing 1, and the two cooling systems 5 are thermally coupled to the heat-generating device 200 in parallel with each other, so as to achieve the parallel connection between the two heat dissipation systems 3 and the thermal coupling with the heat-generating device 200, such that each of the two heat dissipation systems 3 can provide cooling liquid to the heat-generating device 200 through its respective cooling system 5 and exchange heat with the heat-generating device 200. In this way, the two heat dissipation systems 3 can operate alternatively to achieve the single-system operation mode, or the two heat dissipation systems 3 can also operate simultaneously to achieve the dual-system operation mode, so as to improve the operation flexibility of the vehicle-mounted cooling device 101, increase the cooling capacity of the vehicle-mounted cooling device 101, and expand 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 including six vehicle-mounted cooling devices 101 is 65 kw to 780 kw. It can be seen 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 it can be flexibly adjusted, effectively saving energy.

[0115] In this embodiment, the structures of the cooling systems 5 are the same, and each includes a pressure cooling system 6 and an air cooling system 7 connected in parallel with each other, so as to flexibly switch between the two modes of pressure cooling and air cooling.

[0116] Among them, the pressure cooling system 6 is used to implement the pressure cooling mode. Figures 5 - 7It can be seen that 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 are respectively for the circulation of the refrigerant and the cooling liquid. The two compressors 63 are connected in parallel with each other, and are sequentially arranged on the refrigerant pipeline 62 with the oil separator 66, the condenser 64, and the gas-liquid separator 65. The condenser 64 is thermally coupled with the fan 4, so that the refrigerant in the refrigerant pipeline 62 can flow through the oil separator 66, the condenser 64, and the gas-liquid separator 65 in sequence under the drive of the compressor 63, and then return to the compressor 63, realizing the circulation in the refrigerant pipeline 62, and when flowing through the condenser 64, it can exchange heat with the air flow driven by the fan 4. The heat exchanger 67 is specifically a plate heat exchanger, which is arranged between the condenser 64 and the gas-liquid separator 65. One of its two heat exchange channels 68 is connected to the part of the refrigerant pipeline 62 located between the condenser 64 and the gas-liquid separator 65, and the other is connected to the compression-cooling pipeline 61, and the compression-cooling pipeline 61 is thermally coupled with the heat-generating device 200, so that the cooling liquid in the compression-cooling pipeline 61 can circulate between the heat-generating device 200 and the heat exchanger 67, so that the heat of the heat-generating device 200 can be taken away by the cooling liquid in the compression-cooling pipeline 61, and then flow through the heat exchanger 67, and transfer heat to the refrigerant in the refrigerant pipeline 62 at the heat exchanger 67.

[0117] Although not shown in the figure, a flow meter, a pressure sensor, a temperature sensor, etc. can be provided on the compression-cooling pipeline 61 to monitor parameters such as the flow rate, pressure, and temperature of the cooling liquid circulating in the compression-cooling pipeline 61, which is convenient for adjustment according to the monitoring results and improves the temperature control accuracy of the liquid supply.

[0118] The air-cooling system 7 is used to implement the air-cooling mode. As Figure 7 shown, in this embodiment, the air-cooling system 7 includes an air-cooling pipeline 71 and a surface cooler 72. The air-cooling pipeline 71 is for the circulation of the cooling liquid, and is thermally coupled with the heat-generating device 200 in parallel with the compression-cooling pipeline 61 to realize the parallel connection of the air-cooling system 7 and the compression-cooling system 6, and the surface cooler 72 is arranged on the air-cooling pipeline 71 and is thermally coupled with the fan 4. In this way, the cooling liquid in the air-cooling pipeline 71 can take away the heat of the heat-generating device 200 and transfer heat to the gas driven by the fan 4 when flowing through the surface cooler 72, realizing the cooling of the heat-generating device 200.

[0119] Since the cooling systems 5 of the two heat dissipation systems 3 both include the above-mentioned parallel compression-cooling system 6 and air-cooling system 7, both of the two heat dissipation systems 3 can flexibly switch between the compression-cooling mode and the air-cooling mode.

[0120] Among them, the air-cooling mode can be enabled when the ambient temperature is relatively low. In the corresponding air-cooling mode, only the fan 4 needs to be started, and there is no need to start the compressor 63. The cooling liquid circulates in the air-cooling pipeline 71. When it flows through the heat-generating device 200, it takes away the heat of the heat-generating device 200, and 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 enabled when the ambient temperature is relatively 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 device 200, it takes away the heat of the heat-generating device 200, and when it flows through the heat exchanger 67, it exchanges heat with the refrigerant in the refrigerant pipeline 62, so that the refrigerant in the refrigerant pipeline 62 absorbs the heat of the heat-generating device 200 absorbed by the cooling liquid, and driven by the compressor 63, it flows through the condenser 64, and exchanges heat with the air driven by the fan 4 at the condenser 64, and the air takes away the heat to achieve the compression-cooling process.

[0122] Based on the above settings, in this embodiment, both of the two heat dissipation systems 3 of the vehicle-mounted cooling device 101 have two working modes: air-cooling and compression-cooling, and can freely switch between the compression-cooling mode and the air-cooling mode inside the unit. Moreover, the compression-cooling mode and the air-cooling mode can effectively meet the cooling requirements of the heat-generating device 200 under different ambient temperatures with less energy consumption. Therefore, it can not only further enhance the working flexibility of the vehicle-mounted cooling device 101 and improve the cooling capacity of the vehicle-mounted cooling device 101, but also save energy and reduce emissions.

[0123] And, as Figure 5 shown, in this embodiment, the condenser 64 and the surface cooler 72 of each heat dissipation system 3 are integrated on the same heat exchanger 8 to form a two-in-one device. Specifically, it can be seen from Figure 5 that 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 vertical 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, and these four rows of heat exchange channels 81 are along the air outlet direction (in Figure 5They are also arranged side by side in the thickness direction of the heat exchanger 8. Among them, the row of heat exchange channels 81 farthest from the fan 4 is used as the surface cooler 72, and the other three rows of heat exchange channels 81 are used as the condenser 64. The condenser 64 and the surface cooler 72 share two liquid ports. In this way, the structure is simpler and more compact, the space occupation can be effectively reduced, the space utilization rate can be improved, and the fan 4 can be closer to the two coolers, improving the utilization rate of the air volume, so that both the air-cooled mode and the pressure-cooled mode can make full use of the fan air field to achieve better air-cooled and pressure-cooled effects. In particular, since the surface cooler 72 is located upstream of the condenser 64 along the air outlet direction, the pressure drop is small. Therefore, the heat exchange is more sufficient, and the air-cooled effect can be improved as much as possible under the condition that the number of rows of the heat exchange channels 81 corresponding to the surface cooler 72 is small.

[0124] Moreover, from Figure 5 it can be seen that in this embodiment, the fan 4 is inclined, its longitudinal central axis is perpendicular to the thickness direction of the sloping plate 15 closer to the back plate 11 among the two sloping plates 15, there is an angle with the horizontal plane, and among the two heat exchangers 8 on both sides of the fan 4, one heat exchanger 8 is arranged vertically, and the other heat exchanger 8 is connected to one end of the sloping plate 15 farther from the back plate 11 among the two sloping plates 15, and the other end is inclined downward, so that the distance between the two heat exchangers 8 on both sides of the fan 4 gradually increases along the air outlet direction (or from bottom to top), roughly in a V shape. In this way, it is beneficial to make the air volume of the two coolers of the two heat dissipation systems 3 basically approach, improving the consistency of dual-system refrigeration.

[0125] In this embodiment, all 4 compressors 63 are variable-frequency compressors, and both 2 fans 44 are variable-frequency fans. These 4 compressors 63 and 2 fans 4 are frequency-converted controlled by 6 drive boards (located in the electrical box) to prevent repeated start and stop, reduce noise, extend the service life, accurately control the temperature, effectively save energy, and improve the adaptability of the whole machine to complex usage environments.

[0126] As Figure 6 shown, in this embodiment, the two groups 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 in the housing 1 along the length direction of the vehicle body 102 and are symmetrically arranged about the middle of the length direction of the housing 1. And the two groups 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 pressure-cooling pipeline 61 close to the back plate 11 (also the side close to the channel 103) in the housing 1. In this way, the overall layout of the machine is compact and reasonable.

[0127] Moreover, from Figure 6 it can be seen that in this embodiment, the electric control system 2 of the vehicle-mounted cooling device 101 is located on the outermost side in the width direction in the housing 1. Specifically, as Figure 6As shown, in this embodiment, the electric control system 2 includes a first electric control device 21 and a second electric control device 22.
