Detailed Description

The following detailed description of embodiments of the present application refers to the accompanying drawings.

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

It should be understood that the orientation or positional relationship is based on that shown in the drawings. These directional terms are merely for convenience in describing the present application and to simplify the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

In the description of the present application, reference to the terms "first/second" merely distinguishes similar objects and does not denote a particular order, but rather the terms "first/second" may, where permissible, be interchanged with a particular order or sequence so that embodiments of the application described herein may be practiced in other than the order shown or described herein.

The deaeration chamber is an indispensable component in an engine cooling circuit, and has main functions of storing the coolant with increased temperature and volume expansion, performing gas-liquid separation on gas mixed in the cooling circuit, stabilizing system pressure, filling the coolant and the like. In some cases, the deaeration chamber is also called a secondary tank, an expansion tank.

On one hand, the cooling liquid entering the degassing chamber often carries some air, the air-cooled condensate enters the degassing chamber along with the cooling liquid, and the air mixed in the cooling liquid can be automatically separated and enters the upper part; however, when the temperature is low and the degassing flow rate is high, the separation effect of air in the degassing chamber is poor, part of air is drawn into the cooling liquid again by the cooling liquid, and if the air is not separated in time, the air enters the system for circulation again, so that parts such as a water pump are affected.

On the other hand, when the vehicle is off-line from a factory assembly line, coolant needs to be added in advance, generally, in order to improve the adding efficiency, a vacuum adding mode is adopted, namely, after the air tightness detection of a whole vehicle cooling system loop is completed by a filling machine, the system is vacuumized, then the coolant is injected, generally, the adding speed of the coolant is about 15L/min, the production efficiency is influenced by the excessively slow adding speed, meanwhile, more obstacles cannot block the coolant during adding, and otherwise, the adding efficiency is influenced.

However, the existing deaeration chamber usually adopts a pore plate structure for gas-liquid separation, and the pore plate structure needs to be placed inside the deaeration chamber during forming due to structural factors, so that the pore plate structure is used for directly increasing the filling speed of the cooling liquid. If the structural orifice plate trompil of orifice plate is too big, just can't effectively carry out gas-liquid separation, if the structural orifice plate trompil undersize of orifice plate, will influence coolant liquid filling speed, can't compromise coolant liquid filling efficiency and gas-liquid separation.

In view of the above, as shown in fig. 1 to 4, an embodiment of the present invention provides a degassing chamber, which includes a housing 1 and a degassing assembly 2, wherein the housing 1 is provided with a cavity 11, the degassing assembly 2 has a plurality of degassing holes P, the degassing assembly 2 is located in the cavity 11, and the degassing assembly 2 is rotatably connected to the housing 1, so that the degassing assembly 2 is in an open first state or a blocked second state. When the degassing assembly 2 is in the first state of opening, the cooling liquid is injected into the cavity 11, and when the degassing assembly 2 is in the second state of separation, the degassing hole P performs gas-liquid separation on the cooling liquid.

Specifically, the degassing assembly 2 is located in the cavity 11, and the degassing assembly 2 is rotatably connected with the housing 1 so that the degassing assembly 2 is in an open first state or a blocked second state. For example, one end of the degassing assembly 2 is rotatably connected with the inner wall of the housing 1, and the degassing assembly 2 can rotate around the rotating connection with the housing 1. When the degassing chamber is filled with cooling liquid, the cooling liquid generates buoyancy on the degassing component 2, and the degassing component 2 is in a second blocking state. When the degassing component 2 is in the first state of opening, the cooling liquid is injected into the cavity 11, and because the cooling liquid is injected into the cavity 11, the degassing component 2 is in the first state of opening, the injected cooling liquid is prevented from flowing through the degassing component 2, the obstruction of the degassing component 2 is reduced, and the filling efficiency of the cooling liquid is further improved. For example, one end of the degassing component 2 is rotatably connected with the inner wall of the housing 1, the degassing component 2 rotates around the rotating connection part with the housing 1 under the action of self weight, the degassing component 2 is in the first open state, and in the process that the cooling liquid is filled into the cavity 11, the filled cooling liquid does not need to flow through the degassing component 2, so that the obstruction of the degassing component 2 is reduced.

The degassing assembly 2 being in the open first state means that the degassing assembly 2 is rotated about the rotational connection with the housing 1 under the effect of its own weight, so that the degassing assembly 2 is in the open first state. The above description is only given by taking an example that one end of the degassing component 2 is rotatably connected with the inner wall of the housing 1, and the degassing chamber of the embodiment of the present application is not limited, and other rotation situations of the degassing component 2 and the housing 1 should also belong to the protection scope of the degassing chamber of the embodiment of the present application, for example, the rotation position of the degassing component 2 and the housing 1 is located in the middle of the degassing component 2, the degassing component 2 is eccentric at the rotation position, and the degassing component 2 can also be rotated to an open or blocking state.

In one embodiment, as shown in FIG. 3, the number of degassing components 2 is two, and two degassing components 2 are aligned. Specifically, the two degassing assemblies 2 in the second blocking state are at the same height and occupy half of the cross section of the cavity 11 together, and the two degassing assemblies 2 are spliced together to perform gas-liquid separation on the cooling liquid.

Specifically, the rotating shaft 22 is fixed to the inner wall of the housing 1, and the rotating shaft 22 is rotatably connected with the degassing plate 21, so that the degassing assembly 2 can be switched between a first state of being opened and a second state of being blocked. For example, the rotating shaft 22 is spaced apart from the inner wall of the housing 1, and one end of the getter plate 21 has a through hole Q, the rotating shaft 22 is disposed through the through hole Q, and the getter plate 21 can rotate around the rotating shaft 22. Particularly, the rotating shaft 22 penetrates through the through hole Q, and the rotating shaft 22 and the degassing plate 21 are fixed in a rotating mode through pins, so that the degassing plate 21 is limited to be separated from the rotating shaft 22, the failure risk of the degassing plate 21 is reduced, and the reliability of the degassing assembly 2 is improved. Particularly, the rotation range of the degassing component 2 is 0-90 degrees, specifically, the degassing component 2 forms an included angle of 0 degree with the vertical plane under the action of self weight, and the degassing component 2 is in an open first state; the degassing component 2 forms an included angle of 90 degrees with the vertical plane under the buoyancy effect of the cooling liquid, and the degassing component 2 is in a first blocking state. For example, the rotation angle of the deaeration plate 21 about the rotation shaft 22 is 0 ° to 90 °.

Specifically, after the rotating shaft 22 and the degassing plate 21 are both installed on one of the half shells, the rotating shaft 22 is fixed on the inner wall of one of the half shells, the rotating shaft 22 is rotatably connected with the degassing plate 21, and the other half shell is assembled to form the housing 1.

In one embodiment, the rotating shaft 22 is spaced from the inner wall of the housing 1, and the distance between the rotating shaft 22 and the housing 1 is matched with the rotating position of the degassing plate 21. Specifically, when the gas removing plate 21 rotates around the rotating shaft 22 to the second blocked state, the gas removing plate 21 blocks the gap between the rotating shaft 22 and the casing 1, so that the coolant in the cooling circulation loop flows from the upper side to the lower side of the gas removing plate 21, the risk that the coolant flows through the gap between the rotating shaft 22 and the casing 1 is reduced, and the gas-liquid separation effect of the gas removing assembly 2 in the second blocked state is improved.

Specifically, the second partition plate 213 and the first partition plate 212 are both adapted to the cavity 11, for example, the second partition plate 213 and the first partition plate 212 are plate-shaped, the second partition plate 213 and the first partition plate 212 are arranged at an interval, and both the second partition plate 213 and the first partition plate 212 are fixedly connected to the connecting body 211. The connecting body 211 is rotatably connected to the rotating shaft 22, and drives the second separating plate 213 and the first separating plate 212 to rotate around the rotating shaft 22. The second partition plate 213 and the first partition plate 212 are provided with a plurality of deaeration holes P, and the coolant in the cooling circulation circuit is subjected to gas-liquid separation through the deaeration holes P of the second partition plate 213 and the first partition plate 212. For example, the second partition plate 213 and the first partition plate 212 are provided at an interval, the connecting body 211 surrounds the second partition plate 213 and the first partition plate 212, and both the second partition plate 213 and the first partition plate 212 are provided with a plurality of deaeration holes P. Specifically, the connecting body 211, the first partition 212 and the second partition 213 are integrally formed, for example, the degassing plate 21 is a plastic plate, the middle of the plastic plate is hollowed out, and meanwhile, both sides of the plastic plate are drilled to form the degassing holes P.

In one embodiment, the degassing holes P of the second partition plate 213 are offset from the degassing holes P of the first partition plate 212. Specifically, the second partition plate 213 has a plurality of deaeration holes P, and two adjacent deaeration holes P are spaced apart from each other. The first partition plate 212 is provided with a plurality of deaeration holes P, two adjacent deaeration holes P are arranged at intervals, and the deaeration holes P on the second partition plate 213 and the deaeration holes P on the first partition plate 212 are arranged in a staggered manner, so that when the coolant in the cooling circulation loop flows through the deaeration holes P, the coolant forms a labyrinth between the deaeration holes P on the second partition plate 213 and the deaeration holes P on the first partition plate 212, and the gas-liquid separation effect of the deaeration assembly 2 in the second state of separation is improved. In particular, the diameter of the deaeration holes P is 5mm to 8 mm.

In one embodiment, the plurality of degassing holes P of the second partition plate 213 are arranged in a plurality of rows and a plurality of columns, and specifically, the second partition plate 213 is provided with a plurality of degassing holes P, for example, the degassing holes P are circular holes, the plurality of circular holes of the second partition plate 213 are arranged in a plurality of rows and a plurality of columns, and the plurality of rows and columns of circular holes are arranged in an array. Specifically, the diameter of the degassing holes P is 5mm to 8mm, the distance between the degassing holes P in adjacent rows is twice the diameter of the degassing holes P, and the distance between the degassing holes P in adjacent columns is twice the diameter of the degassing holes P.

In one embodiment, the plurality of degassing holes P on the first separating plate 212 are arranged in a plurality of rows and a plurality of columns. The first partition plate 212 is provided with a plurality of degassing holes P, for example, the degassing holes P are round holes, the round holes of the first partition plate 212 are arranged in a plurality of rows and a plurality of columns, and the round holes of the plurality of rows and the plurality of columns are arranged in an array. Specifically, the diameter of the deaeration holes P is 5mm to 8mm, the distance of the deaeration holes P between adjacent rows is twice the diameter of the deaeration holes P, and the distance of the deaeration holes P between adjacent columns is twice the diameter of the deaeration holes P.

In an embodiment, the distance between the second partition plate 213 and the first partition plate 212 is adapted to the diameter of the degassing hole P, specifically, the diameter of the degassing hole P is 5mm-8mm, the distance between the second partition plate 213 and the first partition plate 212 is 10mm, and the distance between the second partition plate 213 and the first partition plate 212 is greater than the diameter of the degassing hole P. For example, the second partition plate 213 is spaced apart from the first partition plate 212 by 8mm to 12 mm. Specifically, the second partition plate 213 and the degassing holes P in the first partition plate 212 are arranged in a staggered manner, and the spacing between the second partition plate 213 and the degassing holes P in the first partition plate 212 in a staggered manner is the same as the diameter of the degassing holes P.

It should be understood that the degassing assembly 2 includes the second partition plate 213 and the first partition plate 212, and in some other cases, the degassing assembly 2 can also include other partition plates, that is, a double-layer or multi-layer structure of the degassing assembly 2. Degassing unit 2 all is equipped with the round hole that a plurality of regular arrays were arranged on second division board 213 and first division board 212, and round hole diameter D is between 5-8mm, and every round hole is 2D along the distance of X direction, Y direction array, and the round hole of upper and lower two-layer separation board has the dislocation, and along X direction, Y direction dislocation distance be 1D, the interval is about 10mm between the two-layer separation board. The two-sided or multi-layer staggered deaeration holes P can prevent the cooling liquid from being involved in bubbles when flowing in at high speed, the decelerated cooling liquid can complete liquid-gas separation in the deaeration chamber, the cooling liquid flows into the bottom of the deaeration chamber, and the gas enters the upper space.

In one embodiment, the degassing component 2 is positioned 5mm to 10mm above the coolant mark level. Be equipped with coolant liquid sign liquid level on degassing chamber's casing 1, coolant liquid sign liquid level is used for instructing the volume of annotating the coolant liquid, and degassing component 2's position is higher than coolant liquid sign liquid level 5mm ~ 10mm for degassing component 2 receives the effect of coolant liquid better. For example, the degassing assembly 2 is located 5mm to 10mm above the normal liquid level of the coolant, thereby facilitating the gas-liquid separation effect.

It should be understood that the coolant liquid sign liquid level is demarcated for the cooling liquid volume in the degassing chamber, and how big or undersize of the volume of coolant liquid is not favorable to the cooling effect in the cooling circuit, and simultaneously, the coolant liquid receives the influence of temperature easily, and degassing assembly 2's position is higher than coolant liquid sign liquid level 5mm ~ 10mm, then under the condition of temperature variation, degassing assembly 2 still can receive the effect of coolant liquid for degassing assembly 2 is in the second state of separation. In the degassing chamber of the application embodiment, the degassing component 2 is 5-10 mm higher than the coolant identification liquid level, the degassing component 2 in the second isolated state is under the buoyancy effect of the coolant, and the gas-liquid separation effect of the degassing component 2 is better.

In one embodiment, as shown in FIG. 4, the degassing chamber further comprises a stopper 3, the stopper 3 is fixed to the cavity 11 of the housing 1, and the stopper 3 is used for limiting the rotation of the degassing assembly 2. Specifically, the stopper 3 is located in the cavity 11 of the housing 1 and fixed on the inner wall of the housing 1, and the stopper 3 limits the rotation of the degassing assembly 2. For example, the stop 3 is positioned on one side where the degassing component 2 is rotatably connected with the adjacent side, and the stop 3 limits the rotation of the degassing component 2, so that the risk that the degassing component 2 continues to rotate from the blocked second state due to the buoyancy of the cooling liquid is reduced, and the reliability of the degassing chamber is improved. It should be understood that the coolant is expanded with heat and contracted with cold by the influence of temperature, and the coolant produces buoyancy to degasification subassembly 2, and under the buoyancy, degasification subassembly 2 rotates to the separation second state from the first state of opening, because dog 3 is fixed in the cavity 11 of casing 1 to restrict degasification subassembly 2 through dog 3 and rotate, improve the stability and the reliability of degasification chamber. In particular, the stop 3 is positioned above the coolant marking level. For example, the degassing assembly 2 is the first state of opening under the dead weight effect, and along with the cooling liquid increases in the degassing chamber, the degassing assembly 2 receives the influence of coolant liquid buoyancy, changes from the first state of opening to the second state of separation, because the position of dog 3 is higher than the coolant liquid and marks the liquid level to restriction degassing assembly 2 further rotates, improves degassing assembly 2's reliability.

In one embodiment, the number of the stoppers 3 is multiple, and the plurality of stoppers 3 are arranged at intervals. Specifically, a plurality of stoppers 3 are provided at intervals at both ends of the rotational connection of the degassing assembly 2 and the housing 1. For example, the number of the stoppers 3 is two, and the two stoppers 3 are respectively located at two ends of the rotational connection between the degassing assembly 2 and the housing 1. In particular, a plurality of stoppers 3 are symmetrically disposed at both ends of the rotational connection of the degassing assembly 2 and the housing 1.

In one embodiment, the stop 3 is located at an end remote from the rotational connection of the degas assembly 2 to the housing 1. Specifically, the stopper 3 is fixed on the inner wall of the housing 1, and the stopper 3 is located at one end far away from the rotational connection between the degassing assembly 2 and the housing 1. It should be understood that the coolant in the degassing chamber generates buoyancy for the degassing assembly 2, and since the stopper 3 is located at the end far away from the rotational connection between the degassing assembly 2 and the housing 1, the degassing assembly 2 abuts against the stopper 3, so that the buoyancy of the coolant is better balanced, the stress strength of the degassing assembly 2 is improved, and the reliability of the degassing assembly 2 is further improved.

In one embodiment, the housing 1 has a liquid inlet 12, a liquid outlet 13 and a filling port 14, the liquid inlet 12 and the liquid outlet 13 are respectively located on different sides of the housing 1, the filling port 14 is located on the top surface of the housing 1, and the liquid inlet 12, the liquid outlet 13 and the filling port 14 are all communicated with the cavity 11.

Specifically, the liquid inlet 12 and the liquid outlet 13 are respectively located on different sides of the housing 1, the liquid inlet 12 is located at a position higher than the liquid outlet 13, the filling port 14 is located on the top surface of the housing 1, and the liquid inlet 12, the liquid outlet 13 and the filling port 14 are all communicated with the cavity 11. For example, when the degassing chamber is filled with the coolant, the filling gun T extends from the filling port 14 into the cavity 11, and the degassing assembly 2 is in the first state of being opened by its own weight. In the cooling cycle process, the cooling liquid flows into the cavity 11 from the liquid inlet 12, and the degassing component 2 performs gas-liquid separation on the flowing cooling liquid to realize the degassing effect.

For better understanding of the deaeration chamber according to the embodiment of the present application, the following description will be made in detail with reference to the deaeration chamber for the coolant filling process and the gas-liquid separation process.

And (3) cooling liquid filling: as shown in fig. 7 and 8, when the degassing chamber is filled with the cooling liquid in a workshop, the filling gun T is inserted into the cavity 11 of the housing 1, the filled cooling liquid passes through the degassing component 2 and is directly filled, the degassing component 2 does not influence or block the filling of the cooling liquid, and the filling fluency of the cooling liquid is improved. When the filling of the cooling liquid is finished, the filling gun T is taken out, the degassing component 2 is influenced by the buoyancy of the cooling liquid, and the degassing component 2 gradually rotates from the open first state to the blocked second state, for example, the degassing component 2 gradually floats up and floats on the preset marking liquid level of the cooling liquid. And current deaeration chamber adopts the orifice plate structure that sets up in inside usually, and during the coolant liquid filling, orifice plate structure separation coolant liquid filling, the risk that gaseous sneaking into of very big increase has still reduced filling efficiency simultaneously. It should be noted that at this point, no cooling liquid is present in the cooling system, and the degassing assembly 2 is rotated by its own weight, so that the degassing assembly 2 is in the open first condition, in particular, the degassing assembly 2 is parallel to the inner wall of the casing 1 (see fig. 7).

Gas-liquid separation process: as shown in fig. 4, the coolant (generally columnar) entering from the degassing port collides inside the degassing chamber (when the flow rate is large), the collision point can be designed according to the internal structure of the kettle body, or the coolant directly flows into the liquid level of the degassing chamber from the water inlet (when the flow rate is small) and is subjected to gas-liquid separation on the degassing hole P on the degassing component 2 to the gas mixed in the coolant before converging into the coolant inside the degassing chamber. For example, the degassing assembly 2 adopts a double-layer structure design of the first partition plate 212 and the second partition plate 213, the flow rate of the cooling liquid is limited by the structure of the double partition plate, meanwhile, the degassing holes P on the first partition plate 212 and the second partition plate 213 are arranged in a staggered manner, so that the cooling liquid flows into the lower part of the second partition plate 213 from the upper part of the first partition plate 212, the path of the cooling liquid is in a labyrinth shape, the degassing hole P is arranged in a staggered manner, the gas-liquid separation effect of the cooling liquid is improved, bubbles in the cooling liquid rise to the upper space in the degassing chamber after moving to the degassing holes P of the degassing assembly 2, the liquid-gas separation is completed, and the separated cooling liquid enters the cooling circuit from the liquid outlet to participate in circulation. It should be noted that the arrangement of the degassing component 2 needs to occupy the cross-sectional space in the degassing chamber as much as possible, and particularly, when the degassing chamber is used for increasing the burst pressure, reinforcing ribs are added in the degassing chamber, and the reinforcing ribs are divided into a plurality of parts for the cavity 11 of the degassing chamber, and then the degassing component 2 can be arranged in the plurality of separated spaces.

It should be understood that the deaeration chamber structure of the embodiment of the present application may be applied to a conventional cooling system of an automobile, and may also be applied to a fuel cell automobile and a hybrid automobile. As the rotatable degassing component 2 is arranged in the degassing chamber, a complex bubble separation structure in a conventional degassing chamber is avoided, so that the requirements on the shape structure of the degassing chamber can be reduced, the forced relation between the degassing port and the water outlet relative position of the degassing chamber is eliminated, and the arrangement design of the degassing chamber can be optimized. Meanwhile, the degassing component 2 can rotate, the filling speed of the cooling liquid is improved, the degassing component 2 is arranged in a fuel cell automobile or a hybrid automobile, great benefits are achieved, the arrangement of engine rooms of the fuel cell automobile, the hybrid automobile and the like is greatly facilitated, and the flexibility of the arrangement of the engine rooms is improved.
