Description

Technical Field

[0001] The utility model relates to the field of heat dissipation, and particularly to a universal liquid cooling device for an ultra-fast charging multi-standard gun line of an electric vehicle. Background Art

[0002] Due to the rapid development of electric vehicles, various countries around the world have successively formulated multiple standards for charging piles. Currently, the four main charging pile standards in the world are: Chinese national standard GB / T, CCS1 American standard (combo / Type 1), CCS2 European standard (combo / Type 2), and Japanese standard CHAdeMO. In addition, the NACS standard released by the electric vehicle company Tesla has gradually been accepted and promoted in the North American market, and the ChaoJi standard jointly formulated by China, Japan, Germany, etc. has also received widespread attention in the industry. Generally speaking, the CCS2 and NACS standards have a relatively high acceptance in the international market, and the GB / T and ChaoJi standards have a relatively high acceptance in the domestic market.

[0003] Therefore, for the international and domestic markets, it is necessary to develop liquid cooling gun lines corresponding to multiple standards, as well as corresponding high-power liquid cooling devices. This not only increases the R & D cost and time, but also leads to extremely high complexity. Once the standard is optimized, it will also cause the scrapping of the inventory of the old standard materials.

[0004] In addition, in order to improve the space utilization rate of the pile body, the current mainstream ultra-fast charging products are single-pile double-gun (that is: one charging pile body, equipped with two gun lines, and the two gun lines share one liquid cooling device). When facing different markets, it is necessary to configure liquid cooling gun lines and liquid cooling units of different standards. Even in some charging piles, two gun lines of different standards may be applied simultaneously (for example: two gun lines on one pile body, one meeting the NACS standard and the other meeting the CCS standard). At this time, the original liquid cooling device cannot meet the usage requirements. Content of the Utility Model

[0005] The main purpose of the utility model is to propose a universal liquid cooling device for an ultra-fast charging multi-standard gun line of an electric vehicle, which overcomes the above technical problems.

[0006] In order to achieve the above purpose, the utility model proposes the following technical solutions:

[0011] A fuel tank is provided with an inlet and an outlet. The inlet is connected to the gun line outlet valve block through a pipeline for the return of the cooling medium, and the outlet is connected to the inlet of the power pump through a pipeline.

[0019] Furthermore, the pressure sensor (3) adopts an inductive pressure sensor.

[0020] Furthermore, the temperature sensor (4) adopts a room temperature and pipe temperature sensor.

It has the advantages that one charging gun line can be used for multiple different charging pile standards, different charging pile standards can be automatically switched, and no manual adjustment is required. It can be compatible with multiple different charging pile standards through a set of liquid cooling unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following reference is made to Figure 1 , and the present invention will be further described:

[0030] A universal liquid cooling device for supercharging multi-standard gun lines of electric vehicles, comprising:

[0031] A power pump 1 for pumping a cooling medium;

[0032] A radiator assembly 5, the inlet of which is connected to the outlet of the power pump 1 through a pipeline;

[0033] The gun line inlet valve block 6 is arranged at the gun line inlet and is connected to the outlet of the radiator assembly 5 through a pipeline.

[0034] The fuel tank 8 is provided with an inlet and an outlet. The inlet is connected to the gun line outlet valve block 7 through a pipeline for the return of the cooling medium, and the outlet is connected to the inlet of the power pump 1 through a pipeline.

[0035] An overflow valve 2 is arranged at the outlet of the power pump 1.

[0036] A pressure sensor 3 and a temperature sensor 4 are arranged at the outlet of the power pump 1.

[0037] The system pumps the cooling medium by the power pump 1 to realize the circulation and cooling of the cooling medium in the system. An overflow valve 2 is arranged at the outlet of the power pump 1 to control the pressure value in the system and avoid excessive system pressure. When the system pressure exceeds the specified value, it plays a pressure relief role. A pressure sensor 3 and a temperature sensor 4 are configured at the outlet of the power pump 1 to monitor the pressure and temperature of the cooling medium before entering the radiator assembly 5 to ensure an ideal heat dissipation effect.

[0038] In one embodiment, a fan is arranged in the radiator assembly 5, and the heat in the cooling medium is blown to the external environment through the fan, and the cooled cooling medium enters the gun line inlet.

[0039] The PLC device 9 is communicatively connected to the power pump 1, the pressure sensor 3, the temperature sensor 4, the radiator assembly 5, and the reversing valve 61.

[0040] The PLC device 9 is also communicatively connected to the charging pile control unit.

[0041] In this embodiment, a valve block is configured at each end of the gun line, which are respectively the gun line inlet valve block 6 and the gun line outlet valve block 7, among which is the gun line inlet valve block 6. The system adopts an autonomous operation mode, and the PLC device 9 automatically adjusts the rotation speeds of the power pump 1 and the fan in the radiator assembly 5, and transmits the system status, alarm information, etc. to the charging pile control unit through communication.

[0042] When the PLC receives an instruction, it will execute the action of the reversing valve according to the control logic, open or close the passage corresponding to the CCS or NACS standard interface, so that the gun line of the connected passage can perform the charging operation. After charging, the heated medium returns to the fuel tank (8).

[0043] At least one reversing valve 61 is arranged on the gun line inlet valve block 6.

[0044] In this embodiment, two reversing valves 61 are integrated on the gun line inlet valve block 6.

[0045] The outlet of the reversing valve 61 corresponds to at least two different gun line specifications.

[0046] In this embodiment, each outlet of the reversing valve corresponds to two types of gun line specifications (such as CCS and NACS). If necessary, more types of gun line specifications can also be configured, and only the number of passages of the reversing valve needs to be increased.

[0047] In an alternative embodiment, the pressure sensor 3 is an inductive pressure sensor.

[0048] In an alternative embodiment, the temperature sensor 4 is a room temperature and tube temperature sensor.

[0049] The present application realizes that a set of liquid cooling system can meet the gun line requirements of different standards through the above structure, has good compatibility, and can meet the simultaneous mixed use of different gun lines of the same set of products. (That is: it can realize CCS charging of one gun while realizing NACS charging of another gun); in the present application, the gun line is placed behind the radiator assembly, the pressure-bearing requirement is reduced, and the working condition of the gun line is improved; the switching of gun lines of different standards can be automatically completed by the system without manual adjustment.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0051] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meanings, so it cannot be understood as a limitation on the protection scope of the present invention.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
