DETAILED DESCRIPTION

[0066] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0068] Next, an integrated charging gun cooling system according to an embodiment of the present invention is described.

[0069] like Figures 1 to 6As shown, the integrated charging gun cooling system of an embodiment of the present invention includes: an external cabinet, a first charging gun cooling device 620, a second charging gun cooling device 610, an integrated block 710, a first transfer temperature sensor 731, a second transfer temperature sensor 732 and a controller.

[0070] First, the outer cabinet is described. An upper space and a lower space are formed in the outer cabinet.

[0071] The outer cabinet can provide protection for the charging gun cooling device, and the upper space and the lower space can accommodate two charging gun cooling devices.

[0072] Next, the first charging gun cooling device 620 and the second charging gun cooling device 610 are described. The first charging gun cooling device 620 and the second charging gun cooling device 610 are respectively arranged in the upper space and the lower space, and the first charging gun cooling device 620 has a first liquid outlet pipe 622 for outflow of cooling liquid and a first liquid return pipe 621 for inflow of cooling liquid, and the second charging gun cooling device 610 has a second liquid outlet pipe 611 for outflow of cooling liquid and a second liquid return pipe 612 for inflow of cooling liquid.

[0073] That is, the cooling liquid is provided to one or both charging guns through the two charging gun cooling devices, the first charging gun cooling device 620 and the second charging gun cooling device 610 .

[0074] Next, the integrated block 710 is described. The integrated block 710 is arranged on the inner wall of the outer cabinet, and includes a first accommodating space and a second accommodating space that are independent of each other. The liquid inlet end of the first accommodating space is connected to the first liquid outlet pipe 622 and the second liquid outlet pipe 611. The liquid outlet end of the first accommodating space can be connected to the liquid inlet ends of two charging guns respectively through the first liquid outlet transfer pipe 744 and the second liquid outlet transfer pipe 741. The liquid inlet end of the second accommodating space can be connected to the liquid outlet ends of two charging guns respectively through the first liquid return transfer pipe 743 and the second liquid return transfer pipe 742. The liquid outlet end of the second accommodating space is connected to the first liquid return pipe 621 and the second liquid return pipe 612.

[0075] That is to say, the coolant from the first liquid outlet pipe 622 of the first charging gun cooling device 620 and the coolant from the second liquid outlet pipe 611 of the second charging gun cooling device 610 are mixed in the first accommodating space and evenly divided into the two first liquid outlet transfer tubes 744, and then enter one or two charging guns through the first liquid outlet transfer tube 744 and the second liquid outlet transfer tube 741.

[0076] The coolant passing through one or two charging guns flows into the second accommodating space through the first liquid return transfer tube 743 and / or the second liquid return transfer tube 742 and is mixed, and then enters the first liquid return pipe 621 of the first charging gun cooling device 620 and the second liquid return pipe 612 of the second charging gun cooling device 610.

[0077] Finally, the first transfer temperature sensor 731 and the second transfer temperature sensor 732 are described. The first transfer temperature sensor 731 is inserted into the first accommodation space to detect the first temperature of the coolant in the first accommodation space. The second transfer temperature sensor 732 is inserted into the second accommodation space to detect the second temperature of the coolant in the second accommodation space. The controller connects the first charging gun cooling device 620, the second charging gun cooling device 610, the first transfer temperature sensor 731 and the second transfer temperature sensor 732, and controls the operation of the first charging gun cooling device 620 and the second charging gun cooling device 610 based on the first temperature, the second temperature and the number of docked charging guns.

[0078] The first transfer temperature sensor 731 can accurately detect the temperature of the coolant in the first accommodating space (the temperature of the coolant to enter the charging gun), and the second transfer temperature sensor 732 can accurately detect the temperature of the coolant in the second accommodating space (the temperature of the coolant flowing out of the charging gun), thereby facilitating the controller to control the first charging gun cooling device 620 and the second charging gun cooling device 610 so as to provide the charging gun with cooling liquid that meets the requirements.

[0079] For example, when docking a charging gun, the controller controls the first charging gun cooling device 620 and the second charging gun cooling device 610 to operate at 30% power according to the first temperature and the second temperature.

[0080] For another example, when two charging guns are docked, the controller controls the first charging gun cooling device 620 and the second charging gun cooling device 610 to operate at 60% power according to the first temperature and the second temperature.

[0081] For another example, when two charging guns are docked, when the first charging gun cooling device 620 is in an abnormal state and the second charging gun cooling device 610 is in a normal state, the controller controls the second charging gun cooling device 610 to operate at 95% power according to the first temperature and the second temperature.

[0082] For another example, when docking a charging gun, when the second charging gun cooling device 610 is in an abnormal state and the first charging gun cooling device 620 is in a normal state, the controller controls the first charging gun cooling device 620 to operate at 70% power according to the first temperature and the second temperature.

[0083] In the above integrated charging gun cooling system, the upper space and the lower space in the outer cabinet respectively accommodate the first charging gun cooling device 620 and the second charging gun cooling device 610. The coolant in the first liquid outlet pipe 622 of the first charging gun cooling device 620 and the coolant in the second liquid outlet pipe 611 of the second charging gun cooling device 610 are mixed in the first accommodation space and evenly divided into the two first liquid outlet transfer pipes 744, and then enter one or two charging guns through the first liquid outlet transfer pipe 744 and the second liquid outlet transfer pipe 741. The coolant passing through one or two charging guns flows into the second accommodation space through the first liquid return transfer pipe 743 and the second liquid return transfer pipe 742 and is mixed, and then enters the first liquid return pipe 621 of the first charging gun cooling device 620 and the second liquid return pipe 612 of the second charging gun cooling device 610. The temperature of the coolant in the first accommodating space (the temperature of the coolant that will enter the charging gun) can be accurately detected by the first transfer temperature sensor 731, and the temperature of the coolant in the second accommodating space (the temperature of the coolant flowing out of the charging gun) can be accurately detected by the second transfer temperature sensor 732. The operation of the first charging gun cooling device 620 and the second charging gun cooling device 610 is controlled based on the first temperature, the second temperature, the state of the first charging gun cooling device 620, the state of the second charging gun cooling device 610, and the number of docked charging guns. Thus, one or two charging guns can be cooled by the first charging gun cooling device 620 and the second charging gun cooling device 610, thereby increasing the stability of the cooling of the charging guns. Even if the state of one charging gun cooling device is abnormal, the two charging guns can be cooled. In addition, in the case of extreme heating of the charging gun or extreme ambient temperature, the charging gun can also be cooled well.

[0084] In some embodiments of the present invention, Figure 2 As shown, the integrated liquid cooling radiator also includes a first liquid outlet solenoid valve 724, a second liquid outlet solenoid valve 722, a first liquid return solenoid valve 723 and a second liquid return solenoid valve 721. The first liquid outlet solenoid valve 724 is arranged at the top of the integrated block 710, and its two ends are connected to the first accommodation space and the first liquid outlet pipe 622 respectively. The second liquid outlet solenoid valve 722 is arranged at the top of the integrated block 710, and its two ends are connected to the first accommodation space and the second liquid outlet pipe 611 respectively. The first liquid return solenoid valve 723 is arranged at the top of the integrated block 710, and its two ends are connected to the second accommodation space and the first liquid return pipe 621 respectively. The second liquid return solenoid valve 721 is arranged at the top of the integrated block 710, and its two ends are connected to the second accommodation space and the second liquid return pipe 612 respectively. The controller is also connected to the first liquid outlet solenoid valve 724, the second liquid outlet solenoid valve 722, the first liquid return solenoid valve 723 and the second liquid return solenoid valve 721 to control the first liquid outlet solenoid valve 724, the second liquid outlet solenoid valve 722, the first liquid return solenoid valve 723 and the second liquid return solenoid valve 721 to adjust their openings.

[0085] For example, if the first charging gun cooling device 620 is abnormal, the first charging gun cooling device 620 can be repaired. During the maintenance, the controller can control the first liquid outlet solenoid valve 724 and the first liquid return solenoid valve 723 to be closed, and control the second liquid outlet solenoid valve 722 and the second liquid outlet solenoid valve 722 to be 100% open.

[0086] For another example, if the first charging gun cooling device 620 is in a poor state, and the second charging gun cooling device 610 is in a good state, the controller can control the opening of the first liquid outlet solenoid valve 724 and the first liquid return solenoid valve 723 to be smaller than the opening of the second liquid outlet solenoid valve 722 and the second liquid return solenoid valve 721, that is, the second charging gun cooling device 610 in a better state is mainly relied on to provide main cooling, and the first charging gun cooling device 620 in a poor state is relied on to provide auxiliary cooling, thereby improving the cooling of the charging gun, avoiding the situation where the second charging gun cooling device 610 in a poor state is used intensively and causing serious failures, and improving the service life of the charging gun cooling device.

[0087] Among them, the first charging gun cooling device 620 may include a first liquid storage tank, a first water pump, a first manifold block, a first microchannel radiator, a first fan and a first liquid outlet temperature sensor. The first liquid storage tank can contain cooling liquid. The liquid inlet end of the first water pump is connected to the first liquid storage tank. The first manifold block is formed with a first chamber and a second chamber that are independent of each other. The liquid inlet end of the first chamber is connected to the liquid outlet end of the first water pump, and its liquid outlet end is connected to the first liquid outlet pipe 622, and the liquid inlet end of the second chamber is connected to the first liquid return pipe 621. The liquid inlet end of the first microchannel radiator is connected to the liquid outlet end of the second chamber of the manifold block, and its liquid outlet end is connected to the first liquid storage tank. The first fan faces the first microchannel radiator to blow or suck air to the first microchannel radiator. The first liquid outlet temperature sensor is inserted into the first chamber to detect the third temperature of the cooling liquid in the first chamber. The controller is also connected to the first water pump, the first fan and the first liquid outlet temperature sensor, and the second liquid return temperature sensor to control the operation of the first water pump and the first fan according to the first temperature and the second temperature. The controller also issues an alarm when the third temperature is higher than the predetermined high temperature, and controls the first liquid outlet solenoid valve 724 and the first liquid return solenoid valve 723 to close.

[0088] During the operation of the first charging gun cooling device 620 and the second charging gun cooling device 610 controlled by the controller, the first liquid outlet temperature sensor detects that the third temperature of the coolant in the first chamber is higher than the predetermined high temperature, indicating that the first charging gun cooling device 620 is abnormal and cannot effectively dissipate the heat of the coolant. At this time, an alarm is issued to facilitate relevant personnel to handle it, and the first liquid outlet solenoid valve 724 and the first liquid return solenoid valve 723 are closed, so that the coolant can only enter and exit through the second liquid outlet solenoid valve 722 and the second liquid return solenoid valve 721, and the coolant is cooled by the second charging gun cooling device 610.

[0089] The controller controls the first water pump and the first fan of the first charging gun cooling device 620 , and can better adjust the cooling effect of the coolant.

[0090] Among them, Figure 3 As shown, the second charging gun cooling device 610 may include a second liquid storage tank 613, a second water pump, a second manifold block 615, a second microchannel radiator 614, a second fan 617 and a second liquid outlet temperature sensor 616. The second liquid storage tank 613 can contain cooling liquid. The liquid inlet end of the second water pump is connected to the second liquid storage tank. The second manifold block 615 is formed with a third chamber and a fourth chamber that are independent of each other. The liquid inlet end of the third chamber is connected to the liquid outlet end of the second water pump, and its liquid outlet end is connected to the second liquid outlet pipe 611, and the liquid inlet end of the fourth chamber is connected to the second liquid return pipe 612. The liquid inlet end of the second microchannel radiator 614 is connected to the liquid outlet end of the fourth chamber of the manifold block, and its second end is connected to the second liquid storage tank 613. The second fan 617 faces the microchannel radiator to blow or suck air to the second microchannel radiator 614. The second liquid outlet temperature sensor 616 is inserted into the third chamber to detect the fourth temperature of the cooling liquid in the third chamber. The controller is also connected to the first water pump, the first fan and the second liquid outlet temperature sensor 616 to control the second water pump and the second fan 617 to operate according to the first temperature and the second temperature. The controller also issues an alarm when the fourth temperature is higher than the predetermined high temperature, and controls the second liquid outlet solenoid valve 722 and the second liquid return solenoid valve 721 to close.

[0091] During the operation of the first charging gun cooling device 620 and the second charging gun cooling device 610 controlled by the controller, the second liquid outlet temperature sensor 616 detects that the fourth temperature of the coolant in the third chamber is higher than the predetermined high temperature, indicating that the second charging gun cooling device 610 is abnormal and cannot effectively dissipate the heat of the coolant. At this time, an alarm is issued to facilitate relevant personnel to handle it, and the second liquid outlet solenoid valve 722 and the second liquid return solenoid valve 721 are closed, so that the coolant can only enter and exit through the first liquid outlet solenoid valve 724 and the first liquid return solenoid valve 723, and the coolant is cooled by the first charging gun cooling device 620.

[0092] The controller controls the second water pump and the second fan 617 of the second charging gun cooling device 610 , and can better adjust the cooling effect of the coolant.

[0093] Further, when the fourth temperature and the third temperature are different, the predetermined high temperature is exceeded. The controller makes the openings of the first liquid return solenoid valve 723 and the second liquid return solenoid valve 721 complementary, and makes the openings of the first liquid outlet solenoid valve 724 and the second liquid outlet solenoid valve 722 complementary, and makes the openings of the first liquid return solenoid valve 723 and the first liquid outlet solenoid valve 724 consistent, and makes the openings of the second liquid return solenoid valve 721 and the second liquid outlet solenoid valve 722 consistent. The controller also controls the opening of the first liquid return solenoid valve 723 to be greater than / lower than the opening of the second liquid return solenoid valve 721 according to whether the third temperature is higher than / lower than the fourth temperature. The controller controls the first water pump to rotate within a first predetermined speed range according to the opening of the first liquid return solenoid valve 723, and controls the second water pump to rotate within a second predetermined speed range according to the opening of the second liquid return solenoid valve.

[0094] The controller makes the openings of the first liquid return solenoid valve 723 and the second liquid return solenoid valve 721 complementary, and makes the openings of the first liquid outlet solenoid valve 724 and the second liquid outlet solenoid valve 722 complementary, and makes the openings of the first liquid return solenoid valve 723 and the first liquid outlet solenoid valve 724 consistent, and makes the openings of the second liquid return solenoid valve 721 and the second liquid outlet solenoid valve 722 consistent. Thus, it is easy to control the flow rate entering the charging gun, and better distribute the coolant to the two charging gun cooling devices.

[0095] Thus, according to the cooling effect of the first charging gun cooling device 620 and the second charging gun cooling device 610 on the coolant, the openings of the corresponding first liquid outlet solenoid valve 724, the second liquid outlet solenoid valve 722, the first liquid return solenoid valve 723 and the second liquid return solenoid valve 721 can be adjusted, so that the charging gun cooling device with relatively good heat dissipation effect can be used for main cooling, and the charging gun cooling device with relatively poor heat dissipation effect can be used for auxiliary cooling, so as to avoid the situation where the charging gun cooling device operates at high intensity but has a short service life.

[0096] The controller controls the first water pump to rotate within a first predetermined speed range according to the opening of the first liquid return solenoid valve 723, and controls the second water pump to rotate within a second predetermined speed range according to the opening of the second liquid return solenoid valve. In this way, an appropriate amount of coolant can be cooled and provided to the charging gun, avoiding excessive or insufficient pressure of the coolant in the integrated charging gun cooling system.

[0097] In some embodiments of the present invention, the outer cabinet includes a base 100, a side plate 200, a partition 500, a front plate 310 and a top cover 410.

The side plate 200 is arranged around the edge of the upper surface of the base 100, and an opening is formed at its front end. The partition 500 is arranged in the middle of the side plate 200 in the vertical direction, so that the space enclosed by the side plate 200 is divided into an upper space and a lower space. The second charging gun cooling device 610 is arranged on the partition 500, and the side plate 200 is formed with a first louver vent 210 at the position facing the first fan and the second fan 617. The front plate 310 is connected to the side plate 200 and is movable. Closing the front plate 310 can close the opening. The front plate 310 is formed with a second louver vent 311 at a position facing the first fan and the second fan 617. The top cover 410 is connected to the top of the side plate 200 and closes the top of the side plate 200.

[0098] like Figure 5 As shown, the base 100 carries the first charging gun cooling device 620, and the partition 500 carries the second charging gun cooling device 610. The side panels 200 and the front panel 310 surround the sides of the two charging gun cooling devices, and the top cover 410 blocks the top of the second charging gun cooling device 610, thereby providing all-round protection for the charging gun cooling device to prevent external pollution and damage to the charging gun cooling device. The first fan and the second fan 617 obtain and exhaust gas from the outside through the first louver vent 210 and the second louver vent 311 to form forced convection, thereby cooling the coolant and improving the heat dissipation efficiency.

[0099] Furthermore, the outer cabinet further includes two filters 330 , both of which are disposed on the front plate 310 and close the second louver air outlet 311 .

[0100] like Figure 4 As shown, the outside air enters the outer cabinet through the second louver vent 311 and the filter 330 , and the filter 330 can filter out impurities in the air, further reducing the pollution and damage of the first charging gun cooling device 620 and the second charging gun cooling device 610 by the outside impurities.

[0101] In some embodiments of the present invention, the base 100 includes a tray 110, a bottom plate 120 and a support plate 130.

The support plate 130 includes a surrounding plate, an upper folding plate and a lower folding plate.

The support plate 130 is connected to the bottom plate 120 through the upper folding plate, and the lower folding plate is vertically connected to the edge of the bottom of the surrounding plate and extends inward.

[0102] like Figure 5 and Figure 6 As shown, the base 100 includes a tray 110, a bottom plate 120 and a support plate 130. The tray 110 can stably carry the charging gun cooling device. The bottom plate 120 stably supports the tray 110, and the cooling pipes (the first liquid outlet pipe 622, the second liquid outlet pipe 611, the first liquid return pipe 621 and the second liquid return pipe 612) of the first charging gun cooling device 620 and the second charging gun cooling device 610 can pass through the first pipe hole 121 on the bottom plate 120 and the second pipe hole 131 on the enclosure. The support plate 130 raises the bottom plate 120 so that the bottom plate 120 is away from the ground to prevent water or pollutants from contaminating the charging gun cooling device. The support plate 130 enclosure provides stable support, the upper fold is horizontally arranged and connected to the enclosure, which can increase the contact area between the support plate 130 and the bottom plate 120, improve the stability of the support, and the lower fold is horizontally arranged and connected to the enclosure, which can increase the contact area between the support plate 130 and the ground, making the structure more stable. Therefore, the base 100 of this structure is light in weight and has a stable structure.

[0103] Furthermore, the base 100 further includes a plurality of reinforcing ribs 140. The reinforcing ribs 140 are formed as grooves with an open front end, the rear of the reinforcing ribs 140 is connected to the enclosure, and the upper and lower ends thereof are respectively connected to the upper folding plate and the lower folding plate.

[0104] like Figure 6 As shown, the base 100 includes reinforcing ribs 140, which are respectively connected to the inner sides of the upper folding plate, the lower folding plate and the enclosure, so as to increase the stability of the structure and prevent the enclosure from bending.

[0105] In some embodiments of the present invention, the outer cabinet further includes a lifting ring 420. The lifting ring 420 is disposed on the upper surface of the top cover 410.

[0106] like Figure 1 As shown, four lifting rings 420 are provided at the four corners of the top cover 410. By lifting the four lifting rings 420, the outer cabinet can be conveniently moved.
