Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle cooling systems, in particular to a cooling liquid static filling universal exhaust structure. Background Art

[0002] As an essential cooling medium for the automotive cooling system, coolant is of great significance to ensure the stable operation of the automotive thermal management system and improve the life, safety and comfort of the vehicle. At present, the expansion kettle is highly integrated with the cooling system components to ease the difficulty of the front cabin layout, which has become the mainstream design direction.

[0003] During the trial production and after-sales maintenance phases, the coolant needs to be manually poured into the expansion kettle to complete the coolant filling. Some models of cars can expel the air in the cooling circuit by turning on the cooling water pump, which is the dynamic coolant filling method. However, the water pipe layout of different models is different. It may be that the height difference between the cooling system components and the expansion kettle of some models is too small or the integration of the cooling system components is too high, forming a local high point in the system. When the vehicle is manually filled with coolant, it is inevitable that gas will accumulate in the cooling system and be difficult to discharge. Even during the filling process, the water pump inlet is always in a state of lack of liquid, resulting in failure of coolant filling, inability to operate the cooling system, or poor exhaust, which has a significant negative impact on the performance of the water pump. Utility Model Content

[0004] The technical problem to be solved by the utility model is to exhaust the air accumulated in the cooling system without activating the cooling water pump to assist the exhaust, that is, to realize the static filling of the coolant. In view of the shortcomings of the prior art, a universal exhaust structure for static filling of the coolant is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A universal exhaust structure for statically filling coolant comprises an expansion kettle, a coolant flow channel plate, a bleed bolt, an exhaust channel, an exhaust port inlet and an exhaust port outlet; the exhaust channel is located inside the expansion kettle, the exhaust port inlet at the bottom is connected to the coolant flow channel plate, and the bleed bolt is arranged at the exhaust port outlet.

[0007] Furthermore, the top of the expansion kettle is provided with a first coolant filling port and a second coolant filling port.

[0008] Furthermore, the cross section of the coolant pipeline inside the coolant flow channel plate is a rectangle with rounded corners.

[0009] Furthermore, the exhaust channel is a cylindrical channel with a cross-sectional diameter of 8 mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] Compared with the prior art, the utility model provides a universal exhaust structure for static filling of coolant. The coolant flow channel plate is the high point of all coolant flow channels in the cooling system except the expansion kettle. The lower end is connected to the coolant flow channel plate, and the upper end is connected to the exhaust channel that runs through the top of the expansion kettle. The air accumulated in the cooling system when adding coolant can be conveniently discharged, which reduces the difficulty of trial production of new vehicle models and subsequent replacement of coolant by users. There is no need to perform exhaust operation separately, which prolongs the life of the cooling system water pump. The exhaust structure is simple and the production difficulty is low. It can meet the requirements of static coolant filling function when multiple vehicle models are used on a platform, and has good practicality and universality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms such as "connection" shall be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, or it may be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example 1

[0020] See also Figure 1 , Figure 2 and Figure 3 , including an expansion kettle 1, a coolant filling port 101, a coolant filling port 2 102, a coolant flow channel plate 2, a bleed bolt 3, an exhaust channel 4, an exhaust port inlet 401, and an exhaust port outlet 402; static filling of coolant can be completed through the coolant filling port 1 and / or the coolant filling port 2 located at the top of the expansion kettle 1, the exhaust channel 4 is located inside the expansion kettle 1, and the exhaust port inlet 401 at its bottom is connected to the position b of the coolant flow channel plate 2, the position a is the position of the cooling system water pump, which is the local low point of the vehicle thermal management integrated module, and is also the local high point of the cooling system except the thermal management integrated module. During the coolant filling process, the gas in the cooling system will be gradually squeezed from there into the coolant flow channel plate 2 located at a high position, and will be discharged from the exhaust port inlet 401 along the flow channel into the exhaust channel 4, and will be discharged from the exhaust port outlet 402 to the cooling circuit, and the bleed bolt 3 will be rotatably connected to the exhaust port outlet 402 along the thread.

[0021] The technical solution provided in the embodiment of the present application has two coolant filling ports that can be used separately or simultaneously, which can speed up the coolant filling efficiency and the variety of choices. The independent exhaust channel can conveniently discharge the air accumulated in the cooling system during the filling process, reduce the difficulty of trial production of new models and subsequent replacement of coolant by users, prevent the water pump from idling or the cooling effect from being reduced due to the difficulty in discharging the accumulated air, extend the life of the cooling system water pump, and improve the cooling effect. The exhaust structure is simple and has low production difficulty. It can meet the requirements of static coolant filling function when used on a multi-model platform, and has good practicality and universality.

[0022] Example 2

[0023] The cross section of the coolant pipeline inside the coolant flow channel plate is a rectangle with rounded corners.

[0024] The technical solution provided in the embodiment of the present application, the rectangle with rounded corners has multiple advantages. On the one hand, the four rounded corners can effectively reduce the resistance of the coolant when flowing in the flow channel, and reduce the energy consumption of the water pump; on the other hand, the layout of complex flow channels in the integrated module can be realized in a limited space. At the same time, due to the low space requirement, it is also conducive to the hot plate welding of the flow channel plate, and has good practicality.

[0025] Example 3

[0026] The exhaust channel is a cylindrical channel with a cross-sectional diameter of 8 mm.

[0027] The technical solution provided in the embodiment of the present application can simplify the difficulty of manufacturing and using the exhaust channel outlet blocking element by designing the exhaust channel as a cylinder. At the same time, the 8mm diameter takes into account both the production difficulty and the exhaust effect, and has good practicality.
