Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle thermal management technical field, especially a heat exchanger and vehicle with it. BACKGROUND

[0002] With the increasing popularity of new energy vehicles, the whole vehicle thermal management system has become one of the key systems in new energy vehicles. In the whole vehicle thermal management system, the heat exchanger is one of the important components. The condenser, especially the supercooling condenser for exchanging heat between the refrigerant and the cooling liquid, not only needs to cool the passenger compartment in the current whole vehicle thermal management system, but also needs to consider the battery pack cooling function.

[0003] In order to realize more efficient and more accurate temperature control, while ensuring the optimal working state of each system, in some whole vehicle thermal management systems, the passenger compartment refrigeration and battery cooling are taken as two independent branches in the refrigeration cycle. This also makes the refrigerant cooled by the condenser change from the original single evaporator circuit of the traditional power system to the multi-branch parallel mode, and generally two parallel branches, one of which cools the passenger compartment through the evaporator, and the other cools the battery through the direct cooling plate. Compared with the indirect cooling system of the battery pack cooler, the direct cooling system of the direct cooling plate requires more refrigerant, so the appearance of multi-branch and direct cooling plate increases the demand for refrigerant flow of the whole vehicle thermal management system.

[0004] When the demand for refrigerant flow increases, the amount of refrigerant in the system also increases. The refrigerant in the system is generally stored in the condenser and the evaporator. The increase of the refrigerant will inevitably lead to the increase of the volume of the drying cylinder. However, in the supercooling condenser, the increase of the height of the drying cylinder will be limited by the height of the core, so the current scheme of increasing the volume of the drying cylinder usually applies a larger diameter drying cylinder, or adds an independent drying tank in the system.

[0005] However, for the scheme of increasing the volume of the drying cylinder, the larger diameter drying cylinder often needs to redesign and develop the cooling module, or even the whole vehicle front end, and the external drying tank also needs to provide installation space for the whole vehicle. In addition, due to the long production time of the traditional power system, the technology and production process are mature, based on the development cost and technical risk consideration, obviously the above two ways of increasing the volume of the drying cylinder make the newly developed vehicle model unable to directly use or simply adjust the parts and system of the traditional vehicle model, resulting in the increase of the development cost of the whole vehicle.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood in combination with the specific circumstances.

[0056] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0057] Embodiment one

[0058] The present embodiment relates to a heat exchanger, which can generally be a condenser in a vehicle thermal management system, and can particularly be a subcooling condenser, but in addition to being a condenser, of course, the heat exchanger can also be a heat exchange component in the vehicle thermal management system which is configured with a drying cylinder structure.

[0059] In combination Figures 1 to 3 As shown, still taking the heat exchanger as an example of a condenser, in the overall structure, the heat exchanger of the present embodiment includes a heat exchanger core 1 and a drying cylinder assembly 2 integrated on one side of the heat exchanger core 1.

[0060] Among them, the drying cylinder assembly 2 includes at least two drying cylinder modules arranged together, the inner cavities of each drying cylinder module are communicated, and the drying cylinder assembly 2 also communicates with the header pipe 103 on the same side of the heat exchanger core 1 to form a refrigerant flow path.

[0061] At this time, as set above, by integrating multiple drying cylinders together on one side of the heat exchanger core 1, on one hand, the multiple drying cylinder modules arranged together can increase the overall volume of the drying cylinder, and on the other hand, the existing drying cylinder structure can be fully utilized in design, avoiding the increase of development cost and the technical risk, so as to meet the demand of increasing the overall volume of the drying cylinder, and also to reduce the development cost of the whole vehicle.

[0062] Based on the above overall introduction, specifically, the drying cylinder module of the embodiment, which is equivalent to the drying cylinder in the prior art, can also be called a drying tank, a liquid storage dryer, a liquid storage dryer, a liquid storage tank, etc. in the field, which plays a role in storing excess refrigerant, filtering and drying refrigerant, and separating gas-liquid state refrigerant in the whole vehicle thermal management system.

[0063] The heat exchanger core 1 in the embodiment is similar to the core structure used in the existing condenser, which mainly includes a liquid collecting pipe 103 arranged on both sides, a flat tube 102 connected between the two liquid collecting pipes 103, and an inlet and outlet assembly 104 arranged on one side of the liquid collecting pipe 103. The inlet and outlet assembly 104 is provided with a refrigerant inlet and a refrigerant outlet, and a refrigerant inlet passage is arranged between the refrigerant inlet and the liquid collecting pipe 103 to allow the refrigerant to enter the liquid collecting pipe 103, i.e. the heat exchanger core 1. The refrigerant outlet and the liquid collecting pipe 103 are provided with a refrigerant outlet passage to allow the refrigerant to flow out of the heat exchanger core 1.

[0064] It can be understood that by making the heat exchanger core 1 similar to the core structure in the existing condenser, mainly composed of a liquid collecting pipe 103, a flat tube 102 and an inlet and outlet assembly 104, it has the characteristics of simple structure and can fully utilize the existing mature structure, thereby helping to reduce the overall design and preparation cost of the heat exchanger.

[0065] In addition, in specific implementation, as a preferred implementation form, side plates 101 can be further arranged on the upper and lower sides of the flat tube 102 to protect the flat tube 102 and make the overall structure of the heat exchanger core 1 more stable.

[0066] As a feasible implementation form, the import and export assembly 104 can generally adopt a pressing plate arranged on one side of the collecting pipe 103, and the refrigerant import and the refrigerant export are arranged on the pressing plate. In order to facilitate the communication between the refrigerant import and the refrigerant export and the collecting pipe 103, as a preferred implementation, an import pipeline 105 for communicating the refrigerant import and the collecting pipe 103 and an export pipeline 106 for communicating the refrigerant export and the collecting pipe 103 can also be arranged. The import pipeline 105 forms a refrigerant import passage, and the export pipeline 106 forms a refrigerant export passage.

[0067] It is worth noting that in addition to arranging the import pipeline 105 and the export pipeline 106, of course, in some implementations, the pressing plate constituting the import and export assembly 104 is directly connected with the collecting pipe 103, and thus the refrigerant import passage and the refrigerant export passage are also located in the pressing plate, which is also possible.

[0068] In specific implementation, of course, the design, preparation and mutual connection of each component in the heat exchanger core 1, and the flow organization of the refrigerant and the cooling liquid in the collecting pipe 103 and the flat pipe 102 of the heat exchanger core can all refer to the related arrangements in the existing condenser.

[0069] In addition, in order to facilitate the arrangement of the heat exchanger in the overall thermal management system, in the heat exchanger of the present embodiment, supports 4 can generally be arranged on both sides thereof, so as to realize the mounting and fixing of the overall heat exchanger by using the supports 4.

[0070] In the present embodiment, continuing to combine with the heat exchanger shown in Figures 4 to 9 In specific implementation, as a preferred implementation form, the cylinder bodies of each drying cylinder module in the drying cylinder assembly 2 can be independently arranged, and the drying cylinder assembly 2 and the collecting pipe 103 on the same side and each drying cylinder module in the drying cylinder assembly 2 can be connected by the connecting piece 3. At the same time, the refrigerant import and export passages for the refrigerant to pass through are arranged in at least part of the connecting pieces 3 between the drying cylinder assembly 2 and the collecting pipe 103 on the same side and in at least part of the connecting pieces 3 between each drying cylinder module, so that the drying cylinder assembly 2 and the collecting pipe 103 on the same side and the inner cavities of different drying cylinder modules are communicated through the refrigerant import and export passages in the corresponding connecting pieces 3.

[0071] At this time, the different drying cylinder modules are connected by the connecting piece 3, which can realize the connection between the different drying cylinder modules and also help to fully use the structure of the existing drying cylinder, so as to reduce the design and manufacturing cost of the drying cylinder assembly 2. It should be noted that, in specific implementation, for the connecting piece 3 provided with the refrigerant inlet and outlet passage, a through hole can be arranged in the connecting piece 3, so that the through hole serves as the required communication passage.

[0072] It should be noted that, in addition to the two drying cylinder modules, when the system refrigerant demand is large and the vehicle arrangement space meets the requirements, more drying cylinder modules can be arranged in the drying cylinder assembly 2. In addition, the connecting piece 3 can have a block structure, a pipeline structure, or any other shape that meets the connection requirements.

[0073] In specific implementation, the connecting piece 3 and the drying cylinder module, and the connecting piece 3 and the collecting pipe 103 can be fixed by brazing, and the brazing connection can also serve as a sealing function to prevent leakage at the connecting position of the connecting piece 3.

[0074] In the embodiment, it should be noted that, in addition to the independent arrangement of the drying cylinder modules in the drying cylinder assembly 2 and the connection by the connecting piece 3, in other embodiments, the drying cylinder assembly 2 and the same side collecting pipe 103 can also be connected by the connecting piece 3, and the refrigerant inlet and outlet passage can be arranged in part of the connecting piece 3, and the cylinder body of each drying cylinder module in the drying cylinder assembly 2 is integrally formed, and the inner cavities of the drying cylinder modules are directly communicated. Figure 7

[0075] At this time, it should be noted that, when the cylinder body of each drying cylinder module is integrally formed, in some cases, part of the cylinder body is shared between different drying cylinder modules. Moreover, it can be understood that, whether it is a certain drying cylinder part arranged independently as above or a certain drying cylinder part in the drying cylinder assembly 2 with integrally formed cylinder body, it can be regarded as a drying cylinder module and equivalent to a drying cylinder in the prior art.

[0076] In addition, the inner cavities of the drying cylinder modules are directly communicated, which is relative to the communication by the connecting piece 3 with the refrigerant inlet and outlet passage, that is, when the cylinder body of each drying cylinder module is integrally formed, the connecting piece 3 can be omitted, and only the communication passage on the cylinder body can realize the communication of the inner cavities of the drying cylinder modules.

[0077] ​In the specific implementation, the barrel body of each drying barrel module can be integrally formed by extrusion molding, and it can be understood that the barrel body of each drying barrel module is integrally formed, which can increase the reliability of the connection between different drying barrels and improve the overall structural stability of the drying barrel assembly. At the same time, when the barrel body of the drying barrel module is integrally extruded, it can be understood that the plug cover at one end of the drying barrel module can be integrally formed on the barrel body, or after the barrel body is formed, it can be connected to the barrel body by screwing, welding or other methods. The barrel cover at the other end of the drying barrel module can be referred to in the following description to select a detachable setting method or a welded fixed method based on specific design requirements.

[0078] After the barrel body of each drying barrel module is integrally formed, it can be connected to the connecting piece 3 by brazing, or the connecting piece 3 can be integrally formed on the barrel body, as long as the drying barrel assembly 2 can be connected to the same side of the liquid collecting pipe 103 through the connecting piece 3. In addition, after the barrel body of each drying barrel module is integrally formed, the communication channel can be formed by machining to communicate between the drying barrels and to communicate between the drying barrel module close to the liquid collecting pipe 103 and the connecting piece 3.

[0079] In the embodiment, in the specific implementation, each drying barrel module in the drying barrel assembly 2 is generally a circular barrel, but it should be noted that in addition to a circular barrel, each drying barrel module can also be designed as a rectangular barrel or any shape from a circular to a rectangular shape, such as an oval shape, which can be selected according to actual design needs in the specific implementation.

[0080] In addition, for ease of description, two drying barrel modules are still taken as an example in the drying barrel assembly 2, that is, the first drying barrel module 201 and the second drying barrel module 202 are arranged together, and in the specific implementation, the outer diameter (or equivalent outer diameter) of the first drying barrel module 201 and the second drying barrel module 202 can be set according to design requirements, as shown in Figure 4 and Figure 8 As shown in Figure 5 , the height of the first drying barrel module 201 and the second drying barrel module 202 can also be set according to design requirements.

[0081] Specifically, for example, the outer diameters of the first drying cylinder module 201 and the second drying cylinder module 202 can be the same, and the heights of the first drying cylinder module 201 and the second drying cylinder module 202 are also the same; or, the outer diameters of the first drying cylinder module 201 and the second drying cylinder module 202 can be the same, but the heights of the first drying cylinder module 201 and the second drying cylinder module 202 are different; or, the outer diameters of the first drying cylinder module 201 and the second drying cylinder module 202 are different, but the heights of the first drying cylinder module 201 and the second drying cylinder module 202 are the same; or, the outer diameters of the first drying cylinder module 201 and the second drying cylinder module 202 are different, and the heights of the first drying cylinder module 201 and the second drying cylinder module 202 are also different.

[0082] In the embodiment, as shown in Figure 6 and Figure 9 , the line between the centers of mass of the first drying cylinder module 201 and the second drying cylinder module 202 can be arranged parallel to the heat exchanger core 1, or the line between the centers of mass of the first drying cylinder module 201 and the second drying cylinder module 202 can be arranged perpendicular to the heat exchanger core 1, or the line between the centers of mass of the first drying cylinder module 201 and the second drying cylinder module 202 can be arranged inclined to the heat exchanger core 1.

[0083] In this way, by using the various design forms of the outer diameters and heights of the drying cylinder modules in the drying cylinder assembly 2, and arranging the line between the centers of mass of the drying cylinder modules parallel, perpendicular or inclined to the heat exchanger core, it is obviously beneficial to meet different volume and vehicle arrangement requirements, and can increase the application effect of the heat exchanger.

[0084] It should be noted that the size of each drying cylinder module, that is, the design of the outer diameter and height of each drying cylinder module, can be designed based on the system refrigerant amount requirement and the vehicle arrangement space, as long as it can meet the system refrigerant requirement and is beneficial to the arrangement in the vehicle. As for the inclined arrangement between the line between the centers of mass of the drying cylinder modules and the heat exchanger core, the included angle therebetween can also be selected according to the vehicle arrangement space and the surrounding component arrangement requirement, as long as it meets the heat management system and vehicle component setting requirement.

[0085] In the embodiment, as shown in Figure 3 , as a preferred implementation form, the refrigerant flow path of the heat exchanger core 1 can be divided into an upstream portion located upstream of the drying cylinder assembly 2 and a downstream portion located downstream of the drying cylinder assembly 2 along the flow direction of the refrigerant, and the upstream portion includes a plurality of refrigerant processes, and the downstream portion includes one refrigerant process.

[0086] Therefore, by making the upstream portion of the refrigerant flow path in the heat exchanger core 1 include multiple refrigerant flows, and also having a refrigerant flow in the downstream portion, the heat exchange effect of the refrigerant in the heat exchanger can be improved. In specific implementation, the upstream portion may, for example, be three flows, or it may also be other quantities, while the refrigerant flow in the downstream portion may, in addition to one, of course, be set to other quantities as needed.

[0087] In the embodiment, the drying cylinder assembly 2 still includes the first drying cylinder module 201 and the second drying cylinder module 202 arranged together, and the first drying cylinder module 201 is connected to the same-side collecting pipe 3, for example. The inner cavity of the first drying cylinder module 201 is sealed by a cylinder cover, and the first drying cylinder 201 also has refrigerant filtering structure and refrigerant drying structure as in the existing drying cylinder, so as to realize filtering and drying of the refrigerant and ensure the use quality of the refrigerant.

[0088] The cylinder cover on the first drying cylinder module 201 is connected to the cylinder body thereof, and preferably, for example, the cylinder cover on the first drying cylinder module 201 is a detachable cylinder cover. However, in addition to using a detachable cylinder cover, it is also possible for the cylinder cover on the first drying cylinder module 201 to be non-detachable, as long as the service life of the refrigerant filtering structure and the refrigerant drying structure is met.

[0089] In specific implementation, the refrigerant filter structure and the refrigerant drying structure are both arranged by referring to the related structures in the existing drying cylinder, and generally, the refrigerant filtering structure may, for example, be a filter screen or other forms of filter arranged in the first drying cylinder module 201, and the refrigerant drying structure may, for example, be a drying bag filled with drying agent arranged in the first drying cylinder module 201, or other products for drying refrigerant.

[0090] In addition, the detachable cylinder cover may, for example, be screwed on the cylinder body of the first drying cylinder module 201. It can be understood that the first drying cylinder module 201 uses a detachable cylinder cover, which is obviously conducive to cleaning the refrigerant filtering structure and replacing the refrigerant drying structure later, and it is also conducive to meeting the needs of repairing based on helium leak detection, and maintaining the condenser in the after-sales market, etc.

[0091] In the embodiment, the inner cavity of the second drying cylinder module 202 is also sealed by a cylinder cover, and in specific implementation, the second drying cylinder module 202 may, optionally, be provided with refrigerant filtering structure and refrigerant drying structure.

[0092] At this time, preferably, since the refrigerant filtering structure and the refrigerant drying structure in the first drying cylinder module 201 can generally meet the needs of filtering impurities and absorbing moisture, the second drying cylinder module 202 will only play a role of storing liquid, thus the second drying cylinder module 202 may, for example, no longer be provided with the refrigerant filtering structure and the refrigerant drying structure, and the cylinder cover on the second drying cylinder module 202 may also be connected to the cylinder body in a non-detachable manner.

[0093] In a specific implementation, the cylinder cover on the second drying cylinder module 202 may generally be welded to the cylinder body in a brazing manner, and it can be understood that, by adopting the welded cylinder cover on the second drying cylinder module 202 and not providing the refrigerant filtering structure and the refrigerant drying structure therein, the weight and cost of the drying cylinder assembly can be reduced.

[0094] It is worth noting that, in addition to the above-mentioned adoption of the screwed cylinder cover on the first drying cylinder module 201 and the provision of the refrigerant filtering structure and the drying structure therein, and the adoption of the welded cylinder cover on the second drying cylinder module 202, the second drying cylinder module 202 may also be provided with the refrigerant filtering structure and the drying structure.

[0095] Of course, in other implementation forms, the cylinder cover of the first drying cylinder module 201 may also be connected to the cylinder body in other conventional structures according to design needs to meet the sealing requirements of the cylinder body, and the cylinder cover of the second drying cylinder module 202 may also be provided to be detachable, for example, and the second drying cylinder module 202 may also be provided with the refrigerant filtering structure and the drying structure.

[0096] In the embodiment, still taking the heat exchanger of the embodiment as a condenser, the drying cylinder assembly 2 includes two drying cylinder modules, and taking the heat exchanger core 1 containing four refrigerant flows as an example. In use, the refrigerant inlet of the inlet and outlet assembly 104 is connected to the outlet of the compressor to receive the high-temperature and high-pressure refrigerant discharged by the compressor, the refrigerant flows into the heat exchanger core 1 through the inlet and outlet assembly 104 and the inlet pipeline 105, and sequentially flows through the first, second and third flows, flows out from the third flow into the first drying cylinder module 201 and the second drying cylinder module 202, and after drying and filtering in the drying cylinder assembly 2, the refrigerant flows into the fourth flow for further cooling, and then the refrigerant enters the outlet pipeline 106 into the inlet and outlet assembly 104, and flows into the expansion valve from the inlet and outlet assembly 104. Then, after throttling by the expansion valve, heat absorption by the evaporator, and compression by the compressor, the refrigerant flows into the condenser for heat release again, and this cycle is repeated to continuously transfer heat from the low-temperature area to the high-temperature area, so as to achieve effective refrigeration of the passenger compartment and the like.

[0097] The heat exchanger of the embodiment adopts the above structure, and through the plurality of drying cylinder modules arranged on one side of the heat exchanger core 1, the plurality of drying cylinder modules arranged together can realize the function of increasing the overall volume of the drying cylinder assembly, and can also fully utilize the existing drying cylinder structure in design, avoid increasing the development cost, and avoid bringing technical risks.

[0098] Embodiment two

[0099] The embodiment relates to a vehicle provided with the heat exchanger in the embodiment one.

[0100] In the embodiment, the heat exchanger can preferably be a condenser in a vehicle thermal management system, and is a subcooling condenser. In addition to being a condenser, the heat exchanger can of course also be other heat exchange components that should be provided with a drying cylinder.

[0101] The arrangement of the heat exchanger of the embodiment in the vehicle can refer to the conventional arrangement of related components in a vehicle thermal management system on an existing vehicle, and will not be described here.

[0102] In addition, the vehicle of the embodiment can not only meet the demand of increasing the overall volume of the drying cylinder part of the heat exchanger integrated with the drying cylinder, but also help reduce the development cost of the vehicle, and has good practicability.

[0103] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
