Example of a joint structure
Referring to fig. 1, a perspective view of a joint structure 100 according to the present invention is representatively illustrated. In the exemplary embodiment, the joint structure 100 provided by the present invention is illustrated by taking the liquid inlet and outlet joint applied to the heat exchange plate 200 as an example. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to utilize the teachings of the present invention in other types of equipment, and still fall within the scope of the principles of the joint construction 100 as taught by the present invention.
As shown in fig. 1, in the present embodiment, the joint structure 100 at least includes a first cavity 110, a second cavity 120, an inlet pipe 130, and an outlet pipe 140. Referring to fig. 2-5, a front view of the joint structure 100 is representatively illustrated in fig. 2; a top view of joint structure 100 is representatively illustrated in fig. 3; a bottom view of the joint structure 100 is representatively illustrated in fig. 4;
the right side view of fig. 2 is representatively illustrated in fig. 5. The structure, connection mode and functional relationship of the main components of the joint structure 100 according to the present invention will be described in detail below with reference to the above-mentioned drawings.
As shown in fig. 1 to 5, in the present embodiment, the first cavity 110 is disposed on the surface of the heat exchange plate 200 and is communicated with the water inlet of the heat exchange plate 200. The second cavity 120 is disposed on the surface of the heat exchange plate 200 and is communicated with the water outlet of the heat exchange plate 200. This feed liquor pipe 130 communicates in first cavity 110 to be used for with outside pipeline intercommunication, and the feed liquor direction of feed liquor pipe 130 and the feed liquor direction nonparallel of water inlet, promptly, feed liquor pipe 130 and the circulation direction of the confession heat transfer medium of water inlet have the contained angle in the space. That is, there is a change in the flow direction of the heat exchange medium flowing to the water inlet via the liquid inlet pipe 130. The liquid outlet pipe 140 is communicated with the second cavity 120 and is used for being communicated with an external pipeline, and the liquid outlet direction of the liquid outlet pipe 140 is not parallel to the liquid outlet direction of the water outlet, that is, the flowing direction of the heat exchange medium supplied to the liquid outlet pipe 140 and the water outlet has an included angle in space. That is, there is a change in the direction of flow of the heat exchange medium as it flows through the outlet pipe 140 to the outlet. On this basis, the sectional area of the inner cavity of the first cavity 110 is larger than that of the lumen of the liquid inlet pipe 130, and the sectional area of the inner cavity of the second cavity 120 is larger than that of the lumen of the liquid outlet pipe 140. Through the above structural design, when the heat exchange medium flows to the first cavity 110 and the second cavity 120, the cross-sectional area of the cavity is larger than that of the liquid inlet pipe and the liquid outlet pipe, so that the flow resistance of the heat exchange medium in the cavity is smaller, and the pressure loss generated by the joint structure 100 provided by the utility model is reduced.
Specifically, regarding the joint connected between the liquid cooling plate and the water inlet and outlet pipes in the related design, the joint is of a 90-degree bent structure, that is, the inner cavity of the joint is of a 90-degree bent flow channel structure. In this regard, as shown in fig. 1 and 2, the two cavities of the joint structure of the present invention have complete smooth inner cavities, rather than the bent flow channel structure in the related design. Therefore, the utility model can avoid the problem of flow resistance increase of the heat exchange medium caused by the bent flow channel structure in the related design, and is beneficial to further reducing the flow resistance and reducing the pressure loss.
Alternatively, as shown in fig. 1 to 5, in the present embodiment, the first cavity 110 may have a first sidewall 111, and the first sidewall 111 is arranged perpendicular to the surface of the heat exchange plate 200. Also, the second cavity 120 may have a second sidewall 121, and the second sidewall 121 is arranged perpendicular to the surface of the heat exchange plate 200. Accordingly, the inlet pipe 130 is connected to the first sidewall 111, and the outlet pipe 140 is connected to the second sidewall 121. Through the above structural design, the first cavity 110 and the second cavity 120 can be connected with the liquid inlet pipe 130 and the liquid outlet pipe 140 respectively by the side walls thereof, so that the liquid inlet pipe 130 and the liquid outlet pipe 140 can be conveniently arranged, the position of the change of the flowing direction of the liquid is ensured not to be inside the pipeline, and the pipeline is prevented from being bent.
Further, as shown in fig. 1, 3 and 4, based on the structural design that the liquid inlet pipe 130 is connected to the first side wall 111 and the liquid outlet pipe 140 is connected to the second side wall 121, in this embodiment, the liquid inlet pipe 130 and the liquid outlet pipe 140 may be both arranged along the first direction X parallel to the surface of the heat exchange plate 200, and the extension directions of the liquid inlet pipe 130 and the liquid outlet pipe 140 are the same. Through the structural design, the process that the heat exchange medium flows from the liquid inlet pipe 130 to the water inlet has 90-degree flow direction change, and the process that the heat exchange medium flows from the water outlet to the liquid outlet pipe 140 has 90-degree flow direction change. On the basis, the heat exchange medium on the bent flow path from the liquid inlet pipe 130 to the water inlet and from the water outlet to the liquid outlet pipe 140 does not generate a large flow resistance to the heat exchange medium due to the arrangement of the first cavity 110 and the second cavity 120. Moreover, on the basis of ensuring the reduction of the flow resistance, the liquid inlet pipe 130 and the liquid outlet pipe 140 extend along the first direction X parallel to the surface of the heat exchange plate 200, so that the space occupation of the joint structure 100 and the heat exchange plate 200 in the battery box can be further saved, and the improvement of the energy density of the battery is facilitated.
Further, as shown in fig. 1 to 5, based on the structural design that the liquid inlet pipe 130 and the liquid outlet pipe 140 are both arranged along the first direction X and extend in the same direction, in the present embodiment, the first cavity 110 and the second cavity 120 may be arranged at intervals along the first direction X, and orthographic projections of the first cavity 110 and the second cavity 120 on a reference plane are overlapped, where the reference plane is a plane perpendicular to the surface of the heat exchange plate 200 and perpendicular to the first direction X. On the basis, the second sidewall 121 of the second cavity 120 may face the first cavity 110, and the outlet pipe 140 may penetrate through the first cavity 110 along the first direction X and communicate with the second sidewall 121 of the second cavity 120. The first cavity 110 may have an inner wall formed thereon to form a tubular structure for the liquid outlet tube 140 to pass through, or the first cavity 110 may not have an inner wall formed thereon to allow the liquid outlet tube 140 to directly pass through two sidewalls of the first cavity. Through the above structural design, the present invention can further adapt to a specific arrangement form of the liquid inlet and the liquid outlet of the heat exchange plate 200, and simultaneously, the sectional areas of the first cavity 110 and the second cavity 120 can be maximized on the premise of ensuring the arrangement of the parts of the joint structure 100, so as to further optimize the effect of reducing the flow resistance. In other embodiments, the first sidewall 111 of the first chamber 110 may face the second chamber 120, and the liquid inlet pipe 130 may penetrate through the second chamber 120 along the first direction X and communicate with the first sidewall 111 of the first chamber 110.
Specifically, in the present embodiment, an orthographic projection of a portion of the first cavity 110 for the liquid outlet tube 140 to penetrate through on the reference plane is empty, that is, an orthographic projection of a corresponding portion of the second cavity 120 does not overlap with the orthographic projection of the first cavity 110, and a shape of the orthographic projection of the non-overlapping portion is consistent with a cross-sectional shape of the liquid outlet tube. In other words, the non-overlapping portion is not limited to a closed hole shape, and may be a recess or a notch, based on the principle of the present embodiment. In other words, the orthographic projection of the first cavity 110 on the reference plane may have a non-overlapping portion that is not overlapped with the orthographic projection of the second cavity 120 on the reference plane, the second sidewall 121 faces the first cavity 110, and the outlet 140 communicates with the non-overlapping portion of the second sidewall 121 along the first direction X. Or, in other embodiments, the orthographic projection of the second cavity 120 on the reference plane has a non-overlapping portion that is not overlapped with the orthographic projection of the first cavity 110 on the reference plane, the first sidewall 111 is a side of the first cavity 110 facing the second cavity 120, and the liquid inlet pipe 130 is communicated with the non-overlapping portion of the first sidewall 111 along the first direction X.
Alternatively, as shown in fig. 1 to 5, in this embodiment, the joint structure 100 of the present invention may further include a bottom plate 150. Specifically, the bottom plate 150 is used to be connected to the surface of the heat exchange plate 200. On this basis, the first chamber 110 and the second chamber 120 are respectively disposed on the bottom plate 150. The bottom of the first cavity 110 is open to the bottom plate 150, i.e. the first cavity 110 is substantially in the shape of a hood with an open bottom, so that the first cavity 110 is communicated with the water inlet. The bottom of the second cavity 120 is open to the bottom plate 150, i.e. the second cavity 120 is substantially a hood-shaped structure with an open bottom, so that the second cavity 120 is communicated with the water outlet. Accordingly, when the joint structure 100 is connected to the surface of the heat exchange plate 200 by the base plate 150, the first cavity 110 and the heat exchange plate 200 exposed at the bottom opening thereof form a chamber, and the second cavity 120 and the heat exchange plate 200 exposed at the bottom opening thereof form another chamber. With the above-described structure, the present invention can directly or indirectly dispose other structures of the joint structure 100 on the base plate 150 through the base plate 150, so as to enhance the integrity of the joint structure 100 and facilitate the disassembly, assembly, use, processing and transportation of the joint structure 100. In addition, no matter whether the bottom plate 150 is arranged or not, the first cavity 110 and the second cavity 120 adopt a cover-shaped structure, so that the structural complexity of the cavities is reduced, and the processing and molding are easy.
It should be noted that, in other embodiments, the joint structure 100 may not be provided with the bottom plate 150, for example, the first cavity 110 may also be a complete closed cavity structure, and the closed cavity structure is provided with openings communicating with the liquid inlet and the liquid inlet pipe 130 as required. Similarly, the second cavity 120 may also be a complete closed cavity structure, and the closed cavity structure is provided with openings communicating with the liquid outlet and the liquid outlet pipe 140 as required. As another example, the first cavity 110 and the second cavity 120 may have a cover-shaped structure with an open bottom and are directly connected to the surface of the heat exchange plate 200. In addition, the first cavity 110 and the second cavity 120 may be connected by other structures, and the present embodiment is not limited thereto.
Further, based on the structural design of the joint structure 100 including the bottom plate 150, in the embodiment, the first cavity 110, the second cavity 120 and the bottom plate 150 may be integrally formed castings.
Further, based on the structural design that the joint structure 100 includes the bottom plate 150, in this embodiment, the bottom plate 150 and the heat exchange plate 200 may be connected by welding. Through the design, the flow resistance of the system is reduced, and meanwhile, the leakage risk at the joint of the joint structure 100 and the heat exchange plate 200 is reduced.
Further, based on the structural design of the joint structure 100 including the bottom plate 150, in the embodiment, the first cavity 110 and the second cavity 120 may be integrally formed with the bottom plate 150.
Optionally, in this embodiment, the first cavity 110 and the liquid inlet pipe 130 may be integrally formed.
Through the design, the number of the structural joints can be reduced, so that the leakage risk is further reduced.
Optionally, in this embodiment, the second cavity 120 and the liquid outlet tube 140 may be integrally formed.
Through the design, the number of the structural joints can be reduced, so that the leakage risk is further reduced.
Example II Structure of Joint
Based on the above detailed description of the first embodiment of the present invention, a second embodiment of the joint structure 100 will be described below. As shown in fig. 6, fig. 6 representatively illustrates a perspective view of the joint structure 100 in a second embodiment. The design of the joint structure 100 in the second embodiment, which is different from the first embodiment, will be specifically described below with reference to the above-mentioned drawings.
As shown in fig. 6, unlike the first embodiment of the structure design in which the first cavity 110 and the second cavity 120 are spaced along the first direction, in the present embodiment, the first cavity 110 and the second cavity 120 are spaced along the second direction Y, which is perpendicular to the first direction X. On the basis, taking the example that the liquid inlet pipe 130 and the liquid outlet pipe 140 extend in the same direction along the first direction X, the liquid inlet pipe 130 and the liquid outlet pipe 140 are arranged at intervals along the second direction Y. Through the above structural design, the joint structure 100 can further simplify the structural complexity, further reduce the processing difficulty, and further reduce the leakage risk.
In the above two embodiments, the first chamber 110 and the second chamber 120 are designed as a buffer chamber, for example. In various possible embodiments consistent with the design concept of the present invention, the first cavity 110 and the second cavity 120 may also adopt other cavity structures, such as a liquid collecting cavity, an expanding structure integrated with the liquid inlet pipe 140 and the liquid outlet pipe 140, and the like, which are not limited to the above embodiments.
It should be noted herein that the joint structure 100 illustrated in the drawings and described in the present specification is but a few examples of the wide variety of joint structures 100 that the principles of the present invention can be employed with. It should be clearly understood that the principles of this disclosure are in no way limited to any of the details of the joint structure 100 or any of the components of the joint structure 100 shown in the drawings or described in this specification.

In the exemplary embodiment, the heat exchange plate 200 according to the present invention is described as being applied to a battery box. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to utilize the concepts of the present invention in other types of heat generating equipment, and still be within the scope of the principles of heat exchange panel 200 as taught by the present invention.
As shown in fig. 7 and 8, in the present embodiment, a heat exchange plate 200 according to the present invention includes the joint structure 100 according to the present invention and described in detail in the above embodiments.
It should be noted herein that the heat exchanger plates 200 shown in the drawings and described in the present specification are only a few examples of the many types of heat exchanger plates 200 that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are in no way limited to any of the details or any of the components of the heat exchanger plate 200 shown in the drawings or described in the present specification.

In the exemplary embodiment, the battery box provided by the utility model is exemplified by a lithium battery. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to utilize the teachings of the present invention in other types of batteries, and still remain within the scope of the principles of the battery box as set forth herein.
As shown in fig. 9 and 10, in the present embodiment, the battery box proposed by the present invention includes the heat exchange plate 200 proposed by the present invention and described in detail in the above embodiments. Specifically, the heat exchange plate 200 is disposed inside the case 300 of the battery case.
Alternatively, as shown in fig. 9 and 10, in the present embodiment, an end of the liquid inlet pipe 130 remote from the first chamber 110 may protrude outside the case 300, and an end of the liquid outlet pipe 140 remote from the second chamber 120 may protrude outside the case 300. For example, the inlet and outlet pipes 130 and 140 may extend beyond the front beam 310 of the housing 300, respectively. Due to the fact that the design that the quick connector in the related scheme is connected inside the box body 300 increases the risk of leakage of the heat exchange medium inside the box body 300, through the structural design, the connection positions of the liquid inlet pipe 130 and the liquid outlet pipe 140 and an external cooling system can be arranged outside the box body 300, so that the number of pipeline connections inside the box body 300 is reduced, and the liquid leakage risk is further reduced.
It should be noted herein that the battery cases shown in the drawings and described in the present specification are only a few examples of the many types of battery cases in which the principles of the present invention can be employed. It should be clearly understood that the principles of the present invention are in no way limited to any details or any components of the battery box shown in the drawings or described in this specification.
In summary, the joint structure provided by the present invention includes a first cavity and a second cavity, the two cavities are respectively disposed at the connection positions of the liquid inlet pipe and the liquid outlet pipe with the heat exchange plate, and the sectional area of the cavity is larger than the sectional areas of the liquid inlet pipe and the liquid outlet pipe. Through the structural design, when the heat exchange medium flows to the first cavity and the second cavity, the cross section area of the cavity is larger than that of the liquid inlet pipe and the liquid outlet pipe, so that the flow resistance of the heat exchange medium in the cavity is smaller, and the pressure loss generated by the joint structure provided by the utility model is reduced.
