Example one

As shown in fig. 1, an embodiment of the present application provides a component 100 for adjusting an amount of a liquid, which is disposed in a housing for containing the liquid, and includes: a baffle 101 arranged in the shell and a temperature-sensitive expansion part 102 connected with the baffle;

the temperature-sensitive expansion part 102 pushes the baffle 101 to displace in a first direction when the temperature of the liquid rises, and pushes the baffle 101 to displace in a second direction when the temperature of the liquid falls, so as to adjust the size of a space in the shell for containing the liquid, wherein the space is positioned in the second direction of the baffle 101; the first direction is opposite to the second direction.

The baffle 101 adjusts the size of the space in the second direction of the baffle 101 in the shell for containing liquid through self displacement, so that the amount of the liquid in the second direction of the baffle 101 in the shell for containing liquid is adjusted. Specifically, in one possible embodiment, the temperature-sensitive expansion part 102 pushes the baffle 101 to displace downward when the temperature of the liquid increases, and pushes the baffle 101 to displace upward when the temperature of the liquid decreases, so as to adjust the size of the space above the baffle 101 in the housing for containing the liquid.

For better implementation, the baffle 101 may be made of a thermal insulation material, and the thickness of the baffle satisfies a predetermined threshold.

The temperature-sensitive expansion part 102 is connected to one side of the baffle plate, and deforms according to the temperature change of the liquid, so that the baffle plate 101 is pushed or pulled to displace.

Here, the first temperature sensing housing 1024 and the second temperature sensing housing 1025 may be fixedly connected directly, or may be fixedly connected by the pressing block 1026, so that the connection therebetween is further fastened.

In a possible implementation manner, as shown in fig. 3, the component 100 for adjusting the amount of liquid provided in the embodiment of the present application may further include an elastic member 301 connected to the baffle 101, and configured to push the baffle 101 to displace in the second direction. Specifically, the elastic member 301 may be located on the same side or opposite side of the thermal expansion unit 102, and when the thermal expansion unit 102 is contracted and deformed, the baffle 101 is pushed or pulled by the elastic deformation to displace in the second direction.

In a possible implementation manner, as shown in fig. 2, the component 100 for adjusting the amount of liquid provided in the embodiment of the present application may further include: a stopper 201;

the stopper 201 passes through the axial centers of the thermal expansion unit 102 and the baffle 101 and the elastic member 301 to define the displacement paths of the thermal expansion unit 102, the baffle 101 and the elastic member 301. The temperature-sensitive expansion unit 102 may be attached to one end of the stopper 201.

In one possible embodiment, the limit member 201 is used to better limit the displacement path of the push rod 1023 in the temperature-sensitive expansion part 102, but instead of the limit member 201, the displacement path of the push rod 1023 may be limited by the first temperature-sensitive housing 1024 and the second temperature-sensitive housing 1025, so that the push rod 1023 is fixedly connected to the second temperature-sensitive housing 1025, and when the volume of the cavity 1021 changes, the push rod 1023 is pushed to displace in the first direction or in the second direction.

In a possible implementation manner, the component 100 for adjusting the amount of the liquid provided by the embodiment of the present application may further include: at least one fastener; connecting the above-mentioned component 100 and a housing for containing liquid by means of said fixing member;

and/or the fixing member may be fixedly connected to one end of the limiting member 201, to which the thermal expansion unit 102 is not attached.

In another possible embodiment, other fixing methods can be used to fixedly connect the liquid quantity adjusting member 100 and the liquid containing housing together, including: the end of the temperature-sensitive expansion part 102 far away from the limiting part 201 can be directly fixedly connected with the shell containing liquid in a viscose mode and the like, and/or the end of the limiting part 201 without the temperature-sensitive expansion part 102 is directly fixedly connected with the shell containing liquid in a viscose mode and the like.

Based on the same technical concept, the embodiment of the present application further provides a water amount adjusting method and a cooling device, and the like, which can be specifically referred to in the following embodiments.

Example two

The method for adjusting the liquid amount disclosed by the second embodiment of the application comprises the following steps:

Specifically, in one possible embodiment, when the temperature of the liquid rises, the temperature-sensitive expansion part 102 expands and deforms along with the rise of the temperature of the liquid, so as to push the baffle 101 to displace downwards, increase the size of the space above the baffle 101 in the liquid containing shell, and thus increase the amount of the liquid above the baffle 101 in the liquid containing shell. When the temperature of the liquid drops, the temperature-sensitive expansion part 102 contracts and deforms along with the drop of the temperature of the liquid, and under the action of the elastic member 301, for example, under the action of the elastic force of the return spring, the baffle 101 is pushed or pulled to move upwards, so that the size of the space above the baffle 101 in the shell for containing the liquid is reduced, and the amount of the liquid above the baffle 101 in the shell for containing the liquid is reduced.

In one possible embodiment, the temperature-sensitive expansion unit 102 includes: a cavity 1021 and a push rod 1023 which are filled with temperature sensing fillings 1022; and the cavity comprises a first temperature-sensitive housing 1024 and a second temperature-sensitive housing 1025; the second temperature sensing shell 1025 is a telescopic shell; the push rod 1023 is connected with the second temperature sensing shell 1025.

The temperature-sensitive expansion part 102 expands and deforms along with the rise of the temperature of the liquid to push the baffle 101 to displace in a first direction, and specifically comprises:

the temperature sensing filler 1022, such as temperature sensing paraffin, is continuously changed from solid to liquid in the process of increasing the temperature of the liquid, and the volume change caused by the conversion of the solid-liquid state is utilized to generate adaptive deformation of the second temperature sensing shell 1025, such as lengthening the rubber tube, and the push rod 1023 is pushed by the second temperature sensing shell 1025 to generate displacement in the first direction.

The temperature-sensitive expansion part 102 is contracted and deformed with the decrease of the temperature of the liquid, and pushes or pulls the baffle 101 to displace in the second direction under the action of the elastic element 301, for example, under the action of the elastic force of the return spring, which specifically comprises:

the temperature sensing filler 1022, such as temperature sensing paraffin, changes from liquid to solid continuously in the process of reducing the temperature of the liquid, and utilizes the volume change caused by the conversion of the solid-liquid state to generate adaptive deformation of the second temperature sensing shell 1025, such as shortening the rubber tube and generating a space for the displacement of the push rod 1023. At this time, when the elastic member 301 is mounted on the opposite side of the temperature-sensitive expansion part 102, under the action of the elastic member 301, for example, the elastic force of the return spring, the baffle 101 is pushed to displace in the second direction, and the push rod 1023 is pushed to displace in the second direction, so as to return to the cavity 1021; when the elastic member 301 is attached to the same side as the temperature-sensitive expansion part 102, the baffle 101 is pulled to displace in the second direction by the elastic member 301, for example, by the elastic force of the return spring, and the push rod 1023 is pulled to displace in the second direction to return to the cavity 1021.

EXAMPLE III

In order to describe in detail the influence of the embodiments of the present application on the coolant liquid circulation process of the engine cooling device in the implementation process, and the beneficial effects brought by the coolant liquid circulation process, a third embodiment of the present application describes in detail the process of the adjustment method under various operating conditions of the engine in the implementation process.

For convenience of understanding and simplification of explanation, the third embodiment of the present application will be explained in a case where the member 100 for regulating the amount of liquid includes the elastic member 301, the elastic member 301 is attached to the opposite side of the temperature sensitive expansion part 102, and the member 100 for regulating the amount of liquid using the temperature sensitive paraffin and the temperature sensitive filler 1022 is applied to a cooling device of an in-vehicle engine.

Firstly, when the engine is in cold start, the temperature of cooling liquid and lubricating engine oil needs to be rapidly increased under a warm working condition state, so that the operation requirement of the engine is met. Therefore, in the warm-up condition, the temperature-sensitive filler 1022 in the temperature-sensitive expansion portion 102 is in the full solid state, the push rod 1023 is located at the initial position of the displacement in the first direction, specifically, the first direction is downward, and the baffle 101 is located at the maximum stroke of the elastic member 301 under the action of the elastic member 301, so that the minimum space above the baffle 101 in the housing for containing liquid, that is, the minimum amount of liquid above the baffle 101 in the housing for containing liquid, and therefore, when only the amount of liquid above the baffle 101 in the housing for containing liquid participates in the cooling cycle of the engine cooling device, the flow amount of the coolant participating in the cooling cycle is greatly reduced, and the cooling water path of the engine is as shown in fig. 4. At this time, the member 100 for adjusting the amount of liquid is mounted on the cooling device 401 of the engine block, and the coolant passes through the cooling device 402 of the engine head, the thermostat assembly 403, and returns to the water pump 404 from the cooling device 401 of the engine block by the action of the water pump 404, thereby completing one cooling cycle. With the method for adjusting the amount of liquid provided by the embodiment of the application, only the amount of liquid above the baffle 101 in the cooling device 401 of the engine block participates in the cooling cycle of the engine cooling device, so that the flow rate of the cooling liquid participating in the cooling cycle of the engine cooling device is reduced at the moment, and the temperature of the cooling water can be increased by the engine at the fastest speed.

It should be noted that, in the engine cooling water path shown in fig. 4, only necessary components of the cooling water path are drawn, and in the implementation, components to be cooled need to be added to the cooling water path according to a specific model of a specific engine and components involved in the cooling process, for example, when the embodiment of the present application is applied to cooling of a vehicle-mounted engine, components such as a supercharger, an oil cooler, and a warm air need to be added to the engine cooling water path according to a specific model and a specific model of the engine.

As the working load increases, the temperature of the coolant rises, and the temperature sensitive filler 1022 in the temperature sensitive expansion part 102 gradually changes from a solid state to a liquid state, so that the second temperature sensitive housing 1025 is adaptively deformed, thereby pushing 1023 the push rod outwards to generate displacement in a first direction, specifically the first direction is downward, compressing the elastic piece 301 to generate deformation, pushing the baffle plate 101 to generate displacement in the first direction correspondingly, so that the amount of the liquid in the liquid-containing casing above the baffle 101 is steplessly increased during the warming-up process, that is, the amount of the liquid in the liquid-containing casing above the baffle 101 is steplessly increased, in the case where the amount of liquid above the baffle 101 in the engine block cooling device 401 participates in the cooling cycle of the engine cooling device, the liquid quantity of the cooling liquid participating in the cooling circulation of the engine cooling device is increased, and the flow quantity of the cooling liquid required by the heat dissipation of the engine is met.

In addition, in order to further reduce the warm-up time, on the basis of the embodiment of the application, the design of an integrated exhaust manifold can be added in the cooling circulation system of the engine, and the integrated exhaust manifold can utilize the exhaust gas generated by fuel combustion to heat the cooling liquid at the exhaust manifold, so that the temperature of the cooling liquid can be rapidly increased from another angle.

Through this application embodiment the method improves the temperature of coolant liquid fast, can optimize the combustion environment in the combustion chamber, can also optimize the lubricated effect of engine through the viscosity change of accelerating lubricating oil, finally reaches the effect that reduces wearing and tearing, reduction warm-up duration under the engine warm-up operating mode, reduction exhaust emissions.

After the engine warm-up working condition is finished, the low-speed large-load working condition and the partial load working condition are started.

Under the working condition of low speed and large load, the engine has the biggest hidden trouble of having a knocking tendency, which is caused by the higher temperature in the combustion chamber. The occurrence of autoignition of the end mixture before the spark plug does not ignite is a cause of knocking due to the relatively high temperature in the combustion chamber. To solve this problem, sufficient coolant is required to sufficiently cool the engine.

When the cooling device is specifically implemented, the flow of the cooling liquid added with the cooling circulation is adjusted in a stepless mode according to the temperature of the cooling liquid, and the stroke of the baffle 101 is reasonably set, so that the flow of the cooling liquid added with the cooling circulation meets the lowest cooling requirement of an engine, and knocking can be avoided. To achieve this, a specific temperature dependence of the travel of the shutter 101 is shown in FIG. 5.

Under part load conditions, the baffle 101 is continuously displaced in a first direction along with the temperature of the coolant, specifically, the first direction is downward, the space above the baffle 101 in the housing for containing the liquid is continuously increased, that is, the liquid amount above the baffle 101 in the housing for containing the liquid is continuously increased, and the flow rate of the coolant participating in the cooling cycle of the engine cooling device is increased under the condition that only the liquid amount above the baffle 101 in the cooling device 401 of the engine cylinder block participates in the cooling cycle of the engine cooling device. After the maximum stroke of the push rod 1023 in the first direction is reached, the thermostat assembly 403 in FIG. 4 is opened and a large cycle is initiated.

The cooling water path of the large circulation coolant is shown in fig. 6. At this time, the member 100 for adjusting the amount of liquid is installed in the cooling device 401 of the engine block, and the coolant flows from the cooling device 401 of the engine block, through the cooling device 402 of the engine head, the thermostat assembly 403, and back to the water pump 404 by the action of the water pump 404, and the coolant flows through the radiator 601 by the action of the thermostat assembly 403, thereby completing one cooling cycle. ,

since the thermostat assembly 403 is open for a large cycle, the radiator 601 participates in the cooling of the coolant, and flows through the expansion tank 602 via the radiator, and then back to the thermostat assembly 403. Therefore, the temperature of the coolant in the cooling cycle of the engine cooling device is lowered, and at this time, the temperature-sensitive expansion part 102 is subjected to contraction deformation, and the baffle 101 is pushed or pulled to be displaced in the second direction by the elastic member 301, specifically, the second direction is upward, so that the space above the baffle 101 in the housing for containing the liquid is reduced, that is, the amount of the liquid above the baffle 101 in the housing for containing the liquid is reduced, and thus, in the case that only the amount of the liquid above the baffle 101 in the cooling device 401 of the engine block participates in the cooling cycle of the engine cooling device, the flow amount of the coolant participating in the cooling cycle of the engine cooling device is reduced. Specifically, the temperature sensitive filler 1022 in the temperature sensitive expansion unit 102 changes from a liquid state to a solid state as the temperature of the coolant decreases, and the second temperature sensitive housing 1025 is deformed adaptively by a change in volume due to a change in solid-liquid state, for example, the rubber tube is shortened, and a space for displacement of the push rod 1023 is created. At this time, under the action of an elastic member, for example, an elastic force of a return spring, the barrier 101 is pushed to displace in the second direction, specifically, the second direction is upward, and the push rod 1023 is pushed to displace in the second direction, so as to return to the cavity 1021. Because the coolant flow participating in the cooling circulation of the engine cooling device is reduced at the moment, the temperature variation of the coolant in the engine cooling device is reduced, the change of the coolant in the engine cooling device is prevented from being too fast, and the temperature variation of the wall surface of the cylinder hole of the combustion chamber is reduced.

Finally, as the engine operating load increases further, the engine cooling demand increases further, gradually moving into full speed, full load conditions.

In the above operating condition, after the thermostat assembly 403 is turned on, as the operating load of the engine is further increased, the temperature of the coolant in the engine cooling device increases, and the temperature-sensitive expansion part 102 expands and deforms as the temperature of the coolant increases, so as to push the baffle 101 to displace in a first direction, specifically, downward. Thus, the space above the baffle 101 in the case that holds liquid is increased, that is, the amount of liquid above the baffle 101 in the case that holds liquid is increased, and therefore, when only the amount of liquid above the baffle 101 in the case that holds liquid participates in the cooling cycle of the engine cooling apparatus, the amount of flow of the coolant that participates in the cooling cycle is increased. Specifically, the temperature-sensitive filler 1022, such as temperature-sensitive paraffin, changes from solid to liquid continuously in the process of increasing the temperature of the liquid, and utilizes the volume change caused by the conversion of the solid-liquid state to generate adaptive deformation on the second temperature-sensitive housing 1025, such as elongating the rubber tube, and pushing the push rod 1023 to generate displacement in a first direction, specifically the first direction is downward, through the second temperature-sensitive housing 1025.

The increased flow of coolant in the cooling unit enhances cooling of the cylinder bore wall, and when the thermostat assembly 403 reaches the 107 c control limit of the peak value, the push rod 1023 in the component 100 according to the exemplary embodiment of the present application is also moved to the displacement stop position, at which time all of the coolant is engaged in the cooling cycle, reaching the maximum cooling capacity of the engine cooling unit, and entering full speed, full load operating mode. At the moment, the engine can meet the cooling requirements of parts such as a cylinder body, a cylinder cover, an oil cooler, a warm air device, a supercharger and the like.

In the full-speed full-load state, the component 100 of the embodiment of the application can cool the exhaust gas by 100k, so that the oil consumption of the automobile in the highway driving state can be reduced, in addition, the design of the integrated exhaust manifold of the cylinder cover can be added, the flow path of the exhaust gas is shortened in the integrated manifold in the cylinder cover, and the heat transfer loss caused by the heat dissipation of the cylinder wall in a short time is controlled in a reasonable range.

Because the embodiment of the application is used for adjusting the space above the baffle 101 in the shell for containing liquid through stepless adjustment, namely, adjusting the liquid amount above the baffle 101 in the shell for containing liquid, under the condition that only the liquid amount above the baffle 101 participates in the cooling circulation of the engine cooling device in the cooling device 401 of the engine cylinder body, the flow rate of the cooling liquid participating in the cooling circulation of the engine cooling device is adjusted in a stepless manner, the cooling requirement under each working condition is met, compared with the condition that the temperature of the cooling liquid can be adjusted only through large circulation and small circulation in the traditional cooling system, the variation of the temperature of the cooling liquid is smaller, the influence of the temperature of the surrounding cooling liquid on the cylinder hole is reduced, and the abrasion of related friction pairs of the cylinder hole can be reduced. Fig. 7a shows the cylinder diameter of the front cylinder hole in the embodiment of the present application, and fig. 7b shows the cylinder diameter of the rear cylinder hole in the embodiment of the present application. In FIG. 7a, the cylinder bore before the embodiment of the present application shows a 701 worn part after the engine is operated, and in FIG. 7b, the cylinder bore after the embodiment of the present application shows no wear.

The baffle plate can move smoothly and be kept horizontal by the combined action of 3 or 4 temperature-sensitive expansion parts 102 and/or elastic parts 301 at different positions.

As shown in fig. 9, at least one mounting hole 901 may be formed on the upper surface and/or the lower surface of the housing 801 for containing the cooling liquid; the member 100 for adjusting the amount of liquid is connected to the member 100 for adjusting the amount of liquid through the mounting hole 901, and the member 100 for adjusting the amount of liquid is fixed to the cooling device. Specifically, in one possible embodiment, a fixing member may be disposed at one end or both ends of the member 100 for adjusting the amount of liquid, and the member 100 for adjusting the amount of liquid may be fixed to the housing 801 for containing the cooling liquid in the cooling device 800 by connecting the fixing member disposed at one end or both ends of the member 100 for adjusting the amount of liquid to the mounting hole 901
