Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile thermal management, in particular to a valve body structure, a thermal management system and a vehicle. BACKGROUND

[0002] With the continuous progress of power systems and the growing market demand, the thermal management system in new energy vehicles is increasingly concerned. The thermal management system can effectively manage and control the heat in the vehicle to improve performance, efficiency and safety. Among them, the vehicle refrigerant three-way valve plays an important role in the thermal management system, which can effectively control the flow of refrigerant to achieve efficient operation and flexible control of the thermal management system.

[0003] Among them, in the thermal management system architecture, the refrigerant valve used in the control of the refrigerant circuit in the refrigerant side circulation is usually a single-function solenoid operated valve (SOV) that generates a magnetic field by energizing and de-energizing the solenoid to push the valve core to move and achieve the opening and closing of the valve. Or use an electronic expansion valve (EXV) to control the flow and flow direction of the refrigerant by adjusting the opening of the valve port. Or use an electrically driven electronic three-way valve to control the flow direction and flow of the refrigerant through electronic signals, allowing the refrigerant to switch or mix between three different channels. Or use a mechanical three-way valve, which can also be used to change the flow direction of the refrigerant or mix different refrigerants.

[0004] However, the solenoid valve or electronic expansion valve has a relatively single function, and can usually only perform a simple on-off operation (on-off), and cannot achieve complex flow regulation or multi-path switching. The cost of the electronic three-way valve is usually high. The mechanical three-way valve is usually prone to stalling, and has problems such as complex structure and large size, which is not conducive to the lightweight of itself and the lightweight of the valve island or flow channel plate where it is installed.

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] As described in the background, in the existing valve structure, the functions of the electromagnetic valve or the electronic expansion valve are relatively single, and they can usually only perform simple on-off operation (on-off), and cannot realize complex flow regulation or multi-path switching. The cost of the electronic three-way valve is usually high. The mechanical three-way valve is usually prone to jamming, and has problems such as complex structure, and the size is relatively large, which is not conducive to the lightweight of itself and the lightweight of the valve island or the flow channel plate on which it is installed.

[0047] To solve the above technical problems, a valve body structure is provided in the first aspect of the present application. The valve body structure comprises a housing, a rotating member and an elastic member. The housing has a receiving cavity, and the housing is provided with a first port, a second port and a third port, which are all in communication with the receiving cavity. The rotating member comprises a rotating shaft and two rotating parts, the rotating shaft is located in the receiving cavity, and the two rotating parts are located at the two ends of the rotating shaft respectively. The rotating shaft and the second port are oppositely arranged, and the two rotating parts are oppositely arranged with the first port and the third port respectively. When the refrigerant enters the receiving cavity from the first port, one of the rotating parts rotates to the third port and blocks the third port, so that the refrigerant flows out from the second port; when the refrigerant enters the receiving cavity from the third port, one of the rotating parts rotates to the first port and blocks the first port, so that the refrigerant flows out from the second port; when the refrigerant enters the receiving cavity from the second port, the rotating parts do not rotate, and the first port and the third port are always in an open state, so that the refrigerant flows out from the first port and / or the third port. In this way, the automatic action of the rotating member is realized when the refrigerant flows from different ports to the valve body structure by using the pressure difference of the refrigerant in each part, thereby realizing the automatic control of the flow direction and flow rate of the refrigerant in the circuit. The valve body structure provided in the present application replaces the electric control valve, and has the characteristics of low cost.

[0048] A thermal management system is provided in the second aspect of the present application. The thermal management system comprises the valve body structure and a valve island. The valve island is sleeved on the valve body structure, and the valve island is provided with a first channel, a second channel and a third channel, which are respectively in communication with the first port, the second port and the third port of the valve body structure. In this way, the valve body structure and the valve island are combined, and the automatic action of the valve body structure is realized by using the pressure difference of the refrigerant in each part of the thermal management system, thereby solving the problem of a large number of refrigerant valves in the thermal management system under the premise that the functional requirements of the system can be realized.

[0049] A vehicle is provided in the third aspect of the present application. The vehicle comprises the thermal management system.

[0050] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0051] The embodiment of the present application provides a valve body structure, a thermal management system and a vehicle. The pressure difference of the refrigerant in each part is utilized to realize the automatic action of the rotating member when the refrigerant flows to the valve body structure from different ports, so that the automatic control of the refrigerant flow direction and flow in the loop is realized. The valve body structure provided by the embodiment of the present application replaces the electric control valve, and has the characteristics of low cost. The specific structure of the valve body structure, the thermal management system and the vehicle provided by the embodiment of the present application will be introduced below with reference to the drawings.

[0052] Reference Figure 1 The embodiment of the present application provides a valve body structure 100 in the first aspect. Wherein the valve body structure 100 can include a shell 200, a rotating member 300 and an elastic member 400. In a possible implementation manner, as shown in the figure, Figure 2 The shell 200 can have an accommodating cavity 210 inside, and the rotating member 300 can be located in the accommodating cavity 210. In the embodiment of the present application, the shell 200 can be provided with a first port 221, a second port 231 and a third port 241, the first port 221, the second port 231 and the third port 241 are all in communication with the accommodating cavity 210, and the first port 221, the second port 231 and the third port 241 can be located on the same side. It can be understood that the refrigerant can be switched or mixed between the three different channels formed by the first port 221, the second port 231 and the third port 241 and the accommodating cavity 210 respectively, so as to realize different fluid paths.

[0053] Continuing to refer to Figure 1 It can be understood that the rotating member 300 can further include a rotating shaft 310 and two rotating parts 320. Further, each rotating part 320 can include a rod body 321 and an end part 322. Wherein in a possible implementation manner, the number of the rod body 321 and the end part 322 can be at least two, which is not limited in the embodiment of the present application. In the embodiment of the present application, the number of the rod body 321 and the end part 322 is taken as two for example. The rotating shaft 310 can be located at the middle position of the accommodating cavity 210, and the rotating shaft 310 can also be located at the remaining position of the accommodating cavity 210, and the two rod bodies 321 can be located at the two ends of the rotating shaft 310 respectively. Wherein one end of each rod body 321 can be connected with the rotating shaft 310, and the other end of each rod body 321 can be connected with the end part 322, so that the two rod bodies 321 are connected with the two end parts 322 respectively. In a possible implementation manner, the rotating shaft 310 can be arranged opposite to the second port 231, and the two end parts 322 can be arranged opposite to the first port 221 and the third port 241 respectively, so as to realize the opening or closing of the first port 221 or the third port 241 by rotating the end part 322.

[0054] In the embodiment of the present application, as shown in Figure 2 When the refrigerant enters the accommodating cavity 210 from the first port 221, the first port 221 at this time is at one end of relatively high pressure. It can be understood that the refrigerant of relatively high pressure exerts different impact forces on the end portion 322 at the first port 221 and the rod body 321 connected with the end portion 322, and at the same time, the refrigerant continues to flow toward the third port 241 after entering the accommodating cavity 210, and flows to the side of the end portion 322 at the third port 241, and also exerts a certain impact force on the end portion 322 at the third port 241. Under the action of different impact forces, the rod body 321 rotates counterclockwise around the rotating shaft 310, and the end portion 322 at the third port 241 is rotated to the third port 241, and the impact force is always pressed toward the end portion 322, so that the end portion 322 at the third port 241 is blocked at the third port 241, that is, it is ensured that the third port 241 is always in a closed state. In addition, the second port 231 at this time is in an open state, and as the only refrigerant outlet in the valve body structure 100, the refrigerant can flow out from the second port 231, so as to realize the communication between the first port 221 and the second port 231.

[0055] It can be understood that after the rod body 321 rotates counterclockwise, the communication cross section between the first port 221 and the second port 231 is increased, which can be more beneficial to the flow of the refrigerant.

[0056] In the embodiment of the present application, as shown in Figure 3 When the refrigerant enters the accommodating cavity 210 from the third port 241, the third port 241 at this time is at one end of relatively high pressure. It can be understood that the refrigerant of relatively high pressure exerts different impact forces on the end portion 322 at the third port 241 and the rod body 321 connected with the end portion 322, and at the same time, the refrigerant continues to flow toward the first port 221 after entering the accommodating cavity 210, and flows to the side of the end portion 322 at the first port 221, and also exerts a certain impact force on the end portion 322 at the first port 221. Under the action of different impact forces, the rod body 321 rotates clockwise around the rotating shaft 310, and the end portion 322 at the first port 221 is rotated to the first port 221, and the impact force is always pressed toward the end portion 322, so that the end portion 322 at the first port 221 is blocked at the first port 221, that is, it is ensured that the first port 221 is always in a closed state. In addition, the second port 231 at this time is in an open state, and as the only refrigerant outlet in the valve body structure 100, the refrigerant can flow out from the second port 231, so as to realize the communication between the third port 241 and the second port 231.

[0057] It can be understood that, after the rod body 321 rotates clockwise, the communication cross section between the third port 241 and the second port 231 is increased, which can facilitate the flow of the refrigerant.

[0058] In the embodiment of the present application, as shown in Figure 4 the second port 231 is at one end of relatively high pressure. It can be understood that, since the second port 231 is at the middle position in the containing cavity 210, the high pressure impact of the refrigerant on the rod body 321 at both ends of the rotating shaft 310 is the same, so that the rod body 321 does not rotate. In this way, the first port 221 and the third port 241 can always be in an open state, and the second port 231 at this time as the only refrigerant inlet in the valve body structure 100 can make the refrigerant enter from the second port 231 and then flow out from the first port 221 and / or the third port 241, thereby realizing the communication of the second port 231 and the first port 221 and the communication of the second port 231 and the third port 241.

[0059] With reference to Figure 1 , on the basis of the above embodiment, the shell 200 can further include an upper shell 220, a middle shell 230 and a lower shell 240. The upper shell 220, the middle shell 230 and the lower shell 240 can be sequentially fixed and connected by welding or screwing, the first port 221 can be formed in the upper shell 220, the second port 231 can be formed in the middle shell 230, and the third port 241 can be formed in the lower shell 240. In a possible implementation, the shell 200 can be a column structure, which is not limited in the embodiment of the present application. The diameters of the upper shell 220, the middle shell 230 and the lower shell 240 decrease in sequence, that is, the diameter of the upper shell 220 is greater than that of the middle shell 230, and the diameter of the middle shell 230 is greater than that of the lower shell 240. In this way, by gradually reducing the diameter, the valve body structure 100 can realize different flow rate control in different parts, and can also facilitate the insertion of the valve body structure 100 on the valve island 600 or the refrigerant flow channel plate.

[0060] With reference to Figure 1On the basis of the above embodiment, the valve body structure 100 may further include: an elastic member 400. The elastic member 400 may be located on one side of the rotating shaft 310, and the two ends of the elastic member 400 may be fixedly connected to the two rod bodies 321 respectively. In one possible embodiment, the elastic member 400 may be a spring, and the distance between the spring and the two rod bodies 321 is the same. It can be understood that when no refrigerant enters the first port 221 and the third port 241, the elastic member 400 can be used to drive the rod body 321 to rotate around the rotating shaft 310, so that the rotating member 300 is always in the middle position, and the first port 221 or the third port 241 is always in an open state.

[0061] Continue to refer Figure 1 , based on the above embodiment, wherein, in a possible implementation manner, the rotating component 300 may further include: a sealing layer 330. The sealing layer 330 may be coated on the outer surface of the end portion 322. In a possible implementation manner, the end portion 322 may be a spherical structure, and the sealing layer 330 may also be a spherical structure, so that the sealing layer 330 can be coated on the outer surface of the end portion 322. Alternatively, the sealing layer 330 may also be set to other shapes, so that the size of the sealing layer 330 can completely block the first port 221 or the third port 241, and the embodiment of the present application is not limited here. In this way, a layer of sealing layer 330 is provided on the outer surface of the end portion 322, which is conducive to achieving the purpose of sealing and noise reduction. For example, the sealing layer 330 may be made of rubber, and the embodiment of the present application is not limited here.

[0062] Continue to refer Figure 1 Based on the above embodiment, in one possible implementation, a first sealing ring 222 may be provided on the outer surface of the upper housing 220, and a second sealing ring 232 may be provided on the outer surface of the middle housing 230. In one possible implementation, there may be at least one first sealing ring 222 and at least two second sealing rings 232. The present embodiment does not limit the number of first and second sealing rings 222 and 232. In this embodiment, one first sealing ring 222 and two second sealing rings 232 are used as an example. The two second sealing rings 232 may be located on the outer surface where the upper housing 220 connects to the middle housing 230, and on the outer surface where the middle housing 230 connects to the lower housing 240, respectively. It is understood that the first sealing ring 222 can be used to prevent external leakage, preventing refrigerant from leaking from the interior of the valve body structure 100 into the external environment, thereby ensuring the sealing and safety of the valve body structure 100. The second sealing ring 232 can be used to prevent internal leakage, ensuring that refrigerant does not leak from one channel to another, thereby ensuring the sealing of the valve body structure 100.

[0063] With reference to the above Figure 1 On the basis of the above embodiments, in a possible implementation, the outer surface of the upper shell 220 can be further provided with external threads 223. In this way, the installation and fixation between the valve body structure 100 and the valve island 600 or the refrigerant flow channel plate can be facilitated.

[0064] With reference to the above Figure 1 On the basis of the above embodiments, in a possible implementation, the upper shell 220 and the middle shell 230 can be provided with a limiting portion 224. It can be understood that the limiting portion 224 can be used for limiting when the valve body structure 100 is installed through the external threads 223, and plays an auxiliary installation role.

[0065] With reference to the above Figure 5 In a second aspect, the embodiments of the present application provide a heat management system 500. The heat management system 500 can include the valve body structure 100 and the valve island 600 described above. In another possible implementation, the heat management system 500 can further include the valve body structure 100 and the refrigerant flow channel plate, which is not limited in the embodiments of the present application. In the embodiments of the present application, the valve island 600 is taken as an example, and the valve island 600 can be a hollow column structure, so that the valve island 600 can be sleeved on the valve body structure 100. In a possible implementation, the valve island 600 can be respectively provided with a first passage 610, a second passage 620 and a third passage 630. The first passage 610, the second passage 620 and the third passage 630 correspond to the first port 221, the second port 231 and the third port 241 of the valve body structure 100 respectively, so that the first passage 610 and the first port 221 of the valve body structure 100 are in communication, the second passage 620 and the second port 231 of the valve body structure 100 are in communication, and the third passage 630 and the third port 241 of the valve body structure 100 are in communication. In this way, the valve body structure 100 is integrated in the valve island 600, and the automatic action of the valve body structure 100 is realized by using the pressure difference of the refrigerant in each part of the heat management system 500. On the premise that the system function requirements can be realized, the problem of a large number of refrigerant valves in the heat management system 500 is solved.

[0066] With reference to the above Figure 5 On the basis of the above embodiments, at least part of the inner surface of the valve island 600 can be provided with internal threads 640. The internal threads 640 can be correspondingly arranged with the external threads 223 of the valve body structure 100. In this way, the internal threads 640 of the valve island 600 can be matched with the external threads 223 of the valve body structure 100, so as to facilitate the installation of the valve island 600 and the valve body structure 100.

[0067] With reference to the above Figure 5On the basis of the above-mentioned embodiments, in the installation process of the valve body structure 100, the limiting portion 224 of the valve body structure 100 can abut against one of the inner side walls of the first channel 610 of the valve island 600, so that the limiting portion 224 has a limiting effect, thereby facilitating the assembly of the valve body structure 100 and the valve island 600.

[0068] The embodiments of the present application provide a vehicle (not shown in the figure) in a third aspect. The vehicle can include the heat management system 500 described above.

[0069] In the embodiments of the present application, the valve body structure 100 provided by the embodiments of the present application can utilize the characteristics that the refrigerants in different parts have pressure differences, so that the automatic action of the rotating member 300 is realized when the refrigerants flow from different ports to the valve body structure 100, thereby realizing the automatic control of the flow direction and flow rate of the refrigerants in the circuit. The valve body structure 100 provided by the embodiments of the present application can replace the electrically controlled valve, and has the characteristics of low cost. In addition, the problem of a large number of refrigerant valves in the heat management system 500 and the need to use electrically controlled valves for control can also be solved.

[0070] The embodiments or implementations in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be mutually referred to.

[0071] It should be noted that the terms "in a specific implementation", "in some embodiments", "in the present embodiment", "exemplarily" and the like in the specification indicate that the described embodiments can include specific features, structures or characteristics, but not necessarily every embodiment includes the specific features, structures or characteristics. In addition, such phrases do not necessarily refer to the same embodiment. In addition, when a specific feature, structure or characteristic is described in combination with an embodiment, it is within the knowledge of those skilled in the art to realize such feature, structure or characteristic in combination with other embodiments that are explicitly or implicitly described.

[0072] Generally, the terms should be understood at least partly by the use in the context. For example, at least partly according to the context, the term "one or more" used in the specification can be used to describe any feature, structure or characteristic in the singular sense, or can be used to describe a combination of features, structures or characteristics in the plural sense. Similarly, at least partly according to the context, terms such as "a" or "said" can be understood to convey singular usage or convey plural usage.

[0073] It should be readily understood that "on," "over," and "above" in the present disclosure are to be interpreted in the broadest context, such that "on" means not only "directly on" but also includes the meaning of "on" with intervening features or layers therebetween, and "over" or "above" includes not only the meaning of "over" or "above" but also the meaning of "over" or "above" with no intervening features or layers therebetween (i.e., directly on).

[0074] In addition, spatially relative terms, such as "beneath", "below", "lower", "above", "upper", and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. The hot management system 500 can have other orientations (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein can likewise be interpreted according to the relative positions of the components in those other orientations.

[0075] Finally, it is to be understood that any other embodiments disclosed herein can be readily combined with any other embodiments disclosed herein. It is contemplated that the present application covers any and all modifications, variations, or alternatives to the embodiments set forth herein that fall within the general scope of the application. The application is to be limited only by the claims and equivalents thereof.
