Description

Technical Field

[0001] This application relates to the technical field of liquid containers, and particularly to a liquid container and a heat exchange mechanism. Background Art

[0002] A liquid container is used to store liquid. During use, the amount of liquid inside will decrease. Usually, a liquid level gauge is designed to monitor the liquid level height in the liquid container, so as to replenish the liquid into the liquid container in time.

[0003] Taking a water tank for storing cooling water in a heat exchange mechanism as an example, in the prior art, the liquid level gauge is arranged on the side wall of the water tank. Specifically, a through hole is opened on the side wall of the water tank, and a connecting member is arranged between the water tank and the liquid level gauge. The connecting member is provided with a connecting channel, and the through hole is communicated with the liquid level gauge through the connecting channel. The water in the water tank can flow out from the through hole and flow along the connecting channel into the liquid level gauge, so as to facilitate the operator to monitor.

[0004] However, since the connecting member is always in water, the connecting channel is easily blocked due to reasons such as rust of the connecting member or impurities in the water, resulting in different liquid levels between the water tank and the liquid level gauge, inaccurate detection, affecting the operator's judgment of the liquid level in the water tank, and the maintenance operation is also relatively complicated.

[0005] Therefore, how to accurately judge whether it is necessary to replenish the liquid into the liquid container, ensure the stability of the liquid level in the liquid container, and at the same time simplify the overall structure and facilitate the maintenance operation is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] The purpose of this application is to provide a liquid container and a heat exchange mechanism, which can accurately judge whether it is necessary to replenish the liquid into the liquid container, ensure the stability of the liquid level in the liquid container, and at the same time simplify the overall structure and facilitate the maintenance operation.

[0007] To solve the above technical problems, this application provides a liquid container, including a housing and a detection part. A through hole communicating with the inner cavity of the housing is provided on the top wall of the housing; the detection part includes a floating member and a connecting rod. The floating member is fixedly arranged at the bottom of the connecting rod. The floating member is located inside the housing. The top end of the connecting rod passes through the through hole and extends outside the housing. The connecting rod can move axially relative to the housing along the through hole.

[0008] When the liquid level in the housing is relatively high, the floating member rises as the liquid level increases, and the length of the connecting rod extending outside the housing is relatively long. When the liquid level in the housing is relatively low, the floating member drops as the liquid level decreases, and the length of the connecting rod inside the housing is relatively long while the length extending outside the housing is relatively short. An operator can judge the liquid level in the housing according to the length of the connecting rod extending outside the housing, and determine whether it is necessary to replenish the liquid into the housing according to the extending height of the connecting rod. Through this detection unit, the liquid level in the housing can be more intuitively reflected, which is more convenient to observe and has a high accuracy rate.

[0009] The structure of this detection unit is relatively simple. It only needs to open a through hole in the top wall of the housing. During installation, only the connecting rod needs to pass through the through hole so that the floating member is inside the housing. The disassembly and assembly operations are relatively convenient, the probability of failure is relatively low, the later maintenance is convenient, the cost is low, and the service life is long.

[0010] Optionally, the detection unit further includes a limiting member, which is arranged at one end of the connecting rod away from the floating member, and at least part of the projection of the limiting member on the top wall of the housing extends beyond the through hole.

[0011] Optionally, the large-diameter end of the conical barrel is arranged towards the side of the floating member, and the diameter of the large-diameter end is larger than the diameter of the through hole.

[0012] Optionally, the connecting rod and the limiting member are fixed by insertion, clamping, threaded cooperation, fasteners or integrally formed; and / or, the connecting rod and the floating member are fixed by insertion, clamping, threaded cooperation, fasteners or integrally formed.

[0013] Optionally, at least one of the limiting member and the floating member is detachably connected to the connecting rod.

[0014] Optionally, the floating member, the connecting rod and the limiting member are all plastic parts.

[0015] Optionally, a scale is further arranged on the outer wall of the connecting rod along its length direction.

[0016] Optionally, the floating member is of a hollow structure.

[0017] Optionally, it further includes a guide cylinder, which is coaxial with the through hole and fixed to the housing. The connecting rod can pass through the guide cylinder and move axially along the guide cylinder.

[0018] This application also provides a heat exchange mechanism, which includes a circulating heat exchange loop and the liquid container as described above. The liquid container is provided with a liquid inlet pipe and a liquid outlet pipe respectively communicating with the inner cavity of the housing, and the liquid inlet pipe and the liquid outlet pipe are respectively communicated with the circulating heat exchange loop.

[0019] The heat exchange mechanism with the liquid container as described above has technical effects similar to those of the above-mentioned liquid container. For the sake of brevity, they will not be elaborated here. Description of the Drawings

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0033] An embodiment of the present application provides a liquid container, as Figure 1 shown. The liquid container includes a housing 1 and a detection part 2. Among them, a liquid is stored in the housing 1, and the detection part 2 is used to detect the liquid level height in the housing 1 so that when the liquid level height is relatively low, an operator can timely replenish the liquid into the housing 1 to make the liquid level height in the housing 1 stable.

[0034] This embodiment also provides a heat exchange mechanism, which includes the above liquid container. At this time, the liquid stored in the liquid container is a coolant such as water or oil. The heat exchange mechanism also includes a circulating heat exchange circuit. The housing 1 is further provided with a liquid inlet 14, a liquid outlet 15 and a liquid replenishing port 15. The liquid inlet 14 is communicated with the circulating heat exchange circuit through a liquid inlet pipe 3, and the liquid outlet 15 is communicated with the circulating heat exchange circuit through a liquid outlet pipe 4. At the same time, the liquid replenishing port 12 is communicated with a liquid replenishing pipe 6 for replenishing liquid into the housing 1.

[0035] The coolant in the housing 1 flows through the circulating heat exchange pipeline to participate in heat exchange. During this process, it is inevitable that some coolant is lost. The detection unit 2 can detect the liquid level height in the housing 1 and timely judge whether it is necessary to replenish the coolant in the housing 1. Specifically, liquid can be replenished into the housing 1 through the liquid replenishing pipe 6 to ensure the stability of the liquid level in the liquid container, and thus ensure the stability of the heat exchange function.

[0036] Of course, the liquid container provided in this embodiment is not limited to being applied in the heat exchange mechanism, and can also be used in other occasions. Correspondingly, the liquid in the housing 1 is not limited to coolants such as water and oil, and can also be other liquids such as alcohol. For the convenience of description, in the following, the liquid container of the heat exchange mechanism with water as the internal liquid will be used as an example for elaboration.

[0037] Specifically, as Figure 2 shown, a through hole 11 is formed in the top wall of the housing 1, and the through hole 11 is communicated with the inner cavity of the housing 1. As Figure 3 shown, the detection unit 2 includes a floating member 21 and a connecting rod 22. Among them, the floating member 21 is fixedly arranged at the bottom of the connecting rod 22. The floating member 21 is located in the inner cavity of the housing 1, and the density of the floating member 21 is less than the density of the liquid (water), so that the floating member 21 can float on the water surface in the housing 1 and can float up and down with the height of the water surface in the housing 1. One end of the connecting rod 22 connected to the floating member 21 is located in the housing 1, and the end of the connecting rod 22 far from the floating member 21 passes through the through hole 11 and extends out of the housing 1. During the floating process of the floating member 21, it can drive the connecting rod 22 to move axially relative to the housing 1 along the through hole 11.

[0038] With such a setting, when the liquid level height in the housing 1 is relatively high, the floating member 21 rises with the increase of the liquid level height, and the length of the connecting rod 22 extending out of the housing 1 is relatively long. When the liquid level height in the housing 1 is relatively low, the floating member 21 drops with the decrease of the liquid level height, and the length of the connecting rod 22 located in the housing 1 is relatively long, and the length extending out of the housing 1 is relatively short. The operator can judge the liquid level height in the housing 1 according to the length of the connecting rod 22 extending out of the housing 1, and judge whether it is necessary to replenish liquid into the housing 1 according to the extension height of the connecting rod 22. Through the detection unit 2, the liquid level height in the housing 1 can be more intuitively reflected, which is more convenient to observe and has a high accuracy rate.

[0039] The structure of the detection part 2 is relatively simple. Only a through hole needs to be opened in the top wall of the housing 1. During installation, only the connecting rod 22 needs to pass through the through hole 11 so that the floating part 21 is located inside the housing 1. The disassembly and assembly operations are relatively convenient, the probability of failure is low, the later maintenance is convenient, the cost is low, and the service life is long.

[0040] Furthermore, as Figure 3 shown, the detection part 2 further includes a limiting part 23. The limiting part 23 is arranged at one end of the connecting rod 22 far from the floating part 21. The limiting part 23 is located outside the housing 1. The projection of the limiting part 23 on the top wall of the housing 1 at least partially extends beyond the through hole 11. When the liquid level height inside the housing 1 is relatively low, the floating part 21 floats downward and drives the connecting rod 22 and the limiting part 23 to descend. The limiting part 23 can abut against the top wall of the housing 1 to limit the connecting rod 22 from completely entering the housing 1 through the through hole 11, avoiding the separation of the connecting rod 22 from the through hole 11 and ensuring the installation stability of the detection part 2.

[0041] Moreover, since the limiting part 23 is located outside the housing 1, it is also convenient for the operator to judge the height of the connecting rod 22 extending out of the housing 1 through the height of the limiting part 23, and then judge the liquid level height, which is convenient for observation. Of course, to further facilitate the observation of the liquid level, a prompt component can also be set on the outer wall of the limiting part 23, such as a coating with a different color from the housing 1, a protruding part, a light-emitting part, etc.

[0042] As Figure 3 shown, the limiting part 23 has a structure of a conical barrel. One end of the connecting rod 22 far from the floating part 21 is fixed to the conical barrel. And the diameter of the large-diameter end of the conical barrel is larger than the diameter of the through hole 11. The large-diameter end is arranged on the side facing the floating part 21. The small-diameter end of the conical barrel can be open or closed, or it can also be in the shape of an umbrella-shaped structure as Figure 3 shown.

[0043] Of course, in this embodiment, the specific structure of the limiting part 23 is not limited. For example, it can also be set as a block structure, which can be a hollow structure or a solid structure. The structure of the conical barrel can increase its external dimension, the limiting effect is stable, and it is convenient to observe the extending height of the connecting rod 22. At the same time, since the conical barrel is only a shell part, while ensuring its external dimension, it can also reduce its weight, which is beneficial for the floating part 21 to float on the liquid surface.

[0044] The fixing method between the connecting rod 22 and the limiting part 23 is not limited. Specifically, it can be fixed by any one of the following fixing methods:

[0045] First, the limiting part 23 is provided with a jack, and the top end of the connecting rod 22 can be inserted into the jack, and the two can be fixed by interference fit;

[0046] Second, the top end of the connecting rod 22 and the limiting member 23 are respectively provided with mutually adapted clamping structures (such as clamping protrusions and clamping grooves), and are fixed by clamping through the clamping structures;

[0047] Third, the limiting member 23 is provided with a threaded hole, and the top end of the connecting rod 22 is provided with a stud, and is fixed by the threaded fit of the stud and the threaded hole;

[0048] Fourth, the limiting member 23 and the connecting rod 22 are fixed by fasteners;

[0049] Fifth, the connecting rod 22 and the limiting member 23 are directly set as an integrally formed structure.

[0050] There is no restriction on the fixing method between the connecting rod 22 and the floating member 21 either. Specifically, the fixing method between the connecting rod 22 and the limiting member 23 above can be referred to. The fixing method between the connecting rod 22 and the floating member 21 and the fixing method between the connecting rod 22 and the limiting member 23 can be the same or different, with simple structure, convenient installation and good flexibility.

[0051] Moreover, among the limiting member 23 and the floating member 21, at least one of them is detachably connected to the connecting rod 22. The detachable connection can refer to the first to fourth types of the above fixing methods. Of course, it can also be a structure in which the limiting member 23, the floating member 21 and the connecting rod 22 are integrally formed. In this way, a notch is provided on the side wall of the through hole 11, and the connecting rod 22 can be installed into the through hole 11 from the notch. When at least one of the limiting member 23 and the floating member 21 is detachably connected to the connecting rod 22, the change to the structure of the housing 1 can be reduced, and the stability of the connecting rod 22 moving in the through hole 11 can be improved.

[0052] A scale can also be provided along the axial direction of the outer wall of the connecting rod 22. There is no specific restriction on this scale. For example, it can be a specific length dimension, such as a specific digital scale in centimeters or millimeters, or it can be only marking lines such as the lowest line, the highest line, the liquid replenishment line, etc. The accuracy of liquid level detection can be further improved through the scale, which is convenient for users to judge the liquid level height in the housing 1 according to the scale.

[0053] There is no restriction on the specific length of the connecting rod 22, and it can be set according to the actual situation. Of course, in this embodiment, the connecting rod 22 can also be not provided with a scale, and the operator can visually estimate the length of the connecting rod 22 extending out of the housing 1 according to experience to judge whether it is necessary to supplement liquid into the housing 1.

[0054] In this embodiment, the floating member 21, the connecting rod 22 and the limiting member 23 are all plastic parts. Of course, the floating member 21, the connecting rod 22 and the limiting member 23 can also be set as metal parts or the like. The plastic parts can make the floating member 21 have a smaller density, and the connecting rod 22 and the limiting member 23 have a lighter weight, so as to ensure that the floating member 21 can stably float on the liquid surface and can be applicable to a variety of liquids with different densities, with good applicability. And when the floating member 21, the connecting rod 22 and the limiting member 23 are all set as plastic parts, the cost can also be reduced.

[0055] In this embodiment, the floating member 21 has a hollow structure. Specifically, it can be a spherical structure or other shapes such as a cuboid, a cube, a cylindrical structure or an irregular structure. The setting of the hollow structure can make the floating member 21 have a smaller density. Of course, the floating member 21 can also be set as a solid structure such as a foam block, which has a lighter weight and can also float on the liquid surface. And when the floating member 21 is set as a plastic part or a metal part and has a hollow structure, it can achieve a smaller density while ensuring its structural stability, not being easily damaged and having a longer service life.

[0056] The liquid container may further include a guide tube (not shown in the figure). The guide tube is coaxially arranged with the through hole 11, and the guide tube is relatively fixed to the housing 1. The connecting rod 22 can pass through the guide tube and move axially relative to the guide tube. The setting of the guide tube can provide a guiding function for the movement of the connecting rod 22, avoiding the situation that the connecting rod 22 tilts and jams during axial movement when the liquid level changes, ensuring the stability of the movement of the connecting rod 22, and further enabling the operator to judge the accuracy of whether replenishment is needed through the length of the connecting rod 22 extending outside the housing 1.

[0057] Specifically, the guide tube can be directly fixed to or integrally formed with the housing 1, or the guide tube can also be indirectly fixed to the housing 1 through a bracket. The guide tube can be located inside the housing 1 or outside the housing 1, or the guide tube directly passes through the through hole 11, with part located inside the housing 1 and part located outside the housing 1.

[0058] As Figure 4 shown, an overflow port 13 is also provided on the wall of the housing 1. When the amount of water replenished into the housing 1 through the liquid replenishing pipe 6 is relatively large and the liquid level rises to the height of the position where the overflow port 13 is located, the continuously replenished water will overflow from the overflow port 13. At the same time, a drain port 17 is provided at the bottom of the housing 1. Through the drain port 17, the water in the housing 1 can be completely discharged. When it is not used for a long time or when the liquid in the housing 1 needs to be replaced, the water in the housing 1 can be completely discharged through the drain port 17. The overflow port 13 can be an opening provided at the top of the side wall of the housing 1. A plugging member or a valve member can be provided at the drain port 17. Under normal conditions, the overflow port 13 is in an open state, and the drain port 17 is in a closed state. When drainage is required, the drain port 17 is opened.

[0059] As shown Figure 2 in the figure, a liquid pump mounting hole 16 is further provided at the top of the housing 1 for mounting the liquid pump 5. The liquid inlet pipe 3 and the liquid outlet pipe 4 of the liquid container are respectively communicated with the inner cavity of the housing 1. The liquid pump 5 is used to provide a circulation power so that the water in the housing 1 can be discharged from the liquid outlet pipe 4 to the circulating heat exchange loop.

[0060] There is no limitation on the specific structure of the housing 1. The housing 1 may be a structure including a main body part and an upper cover. During installation, first install the detection part 2 on the upper cover, and then install the upper cover and the main body part. Or, as shown Figure 2 in the figure, the operator can install the detection part 2 through the liquid pump mounting hole 16 as well.

[0061] As shown Figure 1 , Figure 3 and Figure 4 in the figure, the liquid container further includes a support plate 7. The support plate 7 is fixed to the housing 1. The support plate 7 is provided with through holes 71 corresponding to the above-mentioned respective pipelines (including the liquid inlet pipe 3, the liquid outlet pipe 4 and the liquid replenishing pipe 6). Each pipeline respectively passes through the corresponding through hole 71. The setting of the support plate 7 can provide support for each pipeline, making the overall structure neater and avoiding clutter. Of course, in this embodiment, the pipelines can also be supported by a bracket, and the bracket can be directly fixed or relatively fixed to the housing 1.

[0063] In the present application, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0064] The above is only the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
