DETAILED DESCRIPTION

[0038] The present invention proposes a thermal management device 100 and a vehicle, which can meet the requirements of impact resistance, vibration isolation, and installation reliability.

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 7 As shown, according to the thermal management device 100 in the embodiment of the present invention, the thermal management device 100 may include a refrigerant plate 10 and a plurality of support frames 20 .

[0041] Among them, the refrigerant plate 10 may have a refrigerant flow channel 11, and the refrigerant flow channel 11 can be used for the flow of refrigerant in the thermal management device 100. A plurality of support frames 20 can be connected to the refrigerant plate 10 respectively, and can be configured to be connected to the vehicle frame 200 to position the refrigerant plate 10. At least two of the plurality of support frames 20 can be split structures. With such a configuration, the installation strength of the thermal management device 100 can be improved by using a plurality of support frames 20, thereby improving the impact resistance of the thermal management device 100. In addition, since at least two support frames 20 are split structures, the vibration superposition between the two support frames 20 can be reduced, and the vibration superposition can be avoided from being transmitted to the refrigerant plate 10 to generate greater vibration, and a certain shock-absorbing effect can be achieved. In other words, the vibration transmission between the thermal management device 100 and the entire vehicle can be effectively reduced. At the same time, processing errors can be avoided, resulting in insufficient assembly accuracy of the support frames 20.

[0042] Specifically, the refrigerant plate 10 may be provided with a variety of thermal management components, such as heat exchangers, valves, etc. The thermal management components can be connected to the refrigerant flow channel 11 on the refrigerant plate 10 to realize the thermal management function of the thermal management device 100. During the driving of the vehicle, the multiple support frames 20 connected to the refrigerant plate 10 can be respectively connected to the vehicle frame 200 to provide support for the thermal management device 100. At the same time, the installation strength of the thermal management device 100 on the frame 200 can be improved, thereby improving the impact resistance of the thermal management device 100. It can be understood that it can be applied to vehicles. When the vehicle is subjected to impact and vibration, the multiple support frames 20 can serve as a buffer transition to avoid the vibration and impact on the frame 200 from being directly transmitted to the refrigerant plate 10, thereby reducing the impact and vibration of the thermal management device 100. Therefore, the impact resistance and vibration reliability requirements of the thermal management device 100 can be met.

[0043] In addition, by connecting multiple support frames 20 to the refrigerant plate 10 (in some specific examples, the multiple support frames 20 can be screwed to the refrigerant plate 10), compared to connecting multiple support frames 20 with other thermal management components, the intermediate rings of the size chain can be reduced (that is, the connecting components between the refrigerant plate 10 and the multiple support frames 20 can be reduced), which not only ensures the installation strength but also the installation accuracy, thereby improving the structural stability of the thermal management device 100.

[0044] Therefore, according to the thermal management device 100 in the embodiment of the present invention, the thermal management device can be installed on the frame 200 through multiple support frames 20. The support and buffering effect of the support frames 20 can improve the impact resistance of the thermal management device 100. At the same time, since at least two of the multiple support frames 20 are split structures, the vibration transmission between the thermal management device 100 and the frame 200 can be effectively reduced, thereby improving the NVH of the whole vehicle and extending the life of the thermal management device.

[0045] The structure of connecting the vehicle frame 200 on the multiple support frames 20 in the present invention can be arranged in parallel with each other, or in other forms. Figures 1 to 7 As shown, in some embodiments of the present invention, the plurality of support frames 20 may include a first support frame 21 and a second support frame 22 .

[0046] Among them, the first support frame 21 may have a first mounting structure, the second support frame 22 may have a second mounting structure, and the axis of the first mounting structure and the axis of the second mounting structure have an angle greater than 0°. With this arrangement, the thermal management device 100 can be installed in multiple directions to improve the impact resistance of the thermal management device 100.

[0047] Reference Figure 5 As shown, the axis of the first mounting structure may be AA, and the axis of the second mounting structure may be BB.

[0048] In detail, the first support frame 21 can be connected to the refrigerant plate 10 and the frame 200 respectively, wherein the first mounting structure and the frame 200 can be connected to each other along the axial direction of the first mounting structure so that the impact force can be transmitted along the axial direction of the first mounting structure; similarly, the second support frame 22 can be connected to the refrigerant plate 10 and the frame 200 respectively, wherein the second mounting structure and the frame 200 can be connected to each other along the axial direction of the second mounting structure so that the impact force can be transmitted along the axial direction of the second mounting structure. There is an angle greater than 0° between the axis of the first mounting structure and the axis of the second mounting structure. In other words, the thermal management device 1000 can be subjected to impact forces in different directions, and the impact forces from different directions can be offset to a certain extent to reduce the degree of impact on the thermal management device 100. For example, when the vehicle is subjected to impact or vibration, the first mounting structure can be subjected to a first impact force transmitted from the frame 200, and the second mounting structure can be subjected to a second impact force transmitted from the frame 200. The first impact force can be decomposed into a component force along the axis direction of the second mounting structure, and the component force can be opposite to the direction of the second impact force, thereby offsetting part of the impact force, thereby reducing the impact force on the thermal management device 100.

[0049] Furthermore, the first mounting structure may be a first mounting hole, and a corresponding third mounting hole is also provided on the frame 200, and the first mounting structure and the frame 200 may be threadedly connected by bolts; similarly, the second mounting structure may be a second mounting hole, and a corresponding fourth mounting hole is also provided on the frame 200, and the second mounting structure and the frame 200 may be threadedly connected by bolts. Of course, the first mounting structure may also be a positioning column, and a corresponding through hole is provided on the frame 200, and the positioning column may be inserted into the corresponding through hole on the frame 200, and locked by a locking member (such as a nut, a latch, etc.), so that the first mounting structure, the second mounting structure and the frame 200 are connected. In addition, according to actual conditions, the first mounting structure and the frame 200, and the second mounting structure and the frame 200, may also be connected by buckling, interlocking, etc., in which case the first mounting structure and the second mounting structure will have corresponding structures, all of which are within the scope of protection of the present invention.

[0050] Of course, the axial direction of the first mounting structure may be the same as the axial direction of the second mounting structure. In other words, the first support frame 21 and the second support frame 22 may be installed in the same direction of the refrigerant plate 10. When the vehicle is impacted, the first support frame 21 and the second support frame 22 may simultaneously serve as impact and vibration buffers for the refrigerant plate 10 in the same direction to reduce the impact and vibration received by the refrigerant plate 10 in this direction. In addition, the connection strength between the refrigerant plate 10 and the vehicle frame 200 in this direction may also be improved.

[0051] like Figures 5 to 7As shown, in some embodiments of the present invention, the first support frame 21 may include a middle section 211 , a first connecting portion 212 and a second connecting portion 213 .

[0052] The middle section 211 can extend in the up-down direction, and the upper and lower ends are respectively connected to the first connection part 212 and the second connection part 213. For example, referring to the attached Figure 5 The lower end of the middle section 211 can be connected to the first connection part 212, and the upper end of the middle section 211 can be connected to the second connection part 213; the first connection part 212 can be connected to the refrigerant plate 10, and the second connection part 213 can be used to connect to the frame 200. The first mounting structure is arranged on the second connection part 213 and extends in the front-to-back direction. Therefore, the first support frame 21 can improve the impact resistance of the thermal management device 100 in the front-to-back direction to meet the reliability requirements of impact resistance and vibration resistance.

[0053] Specifically, the first mounting structure is arranged on the second connecting portion 213. In other words, the second connecting portion 213 is connected to the frame 200 through the first mounting structure, and the first mounting structure extends in the front-to-back direction, so that the first mounting structure and the frame 200 can be connected in the front-to-back direction, that is, the impact force on the frame 200 can be transmitted to the first support frame 21 in the front-to-back direction; when the vehicle is driving, the vehicle will be subjected to impact and vibration, and transmitted to the thermal management device 100. At this time, the impact force is transmitted to the first support frame 21 in the front-to-back direction, and because the middle section 211 of the first support frame 21 extends in the up-down direction, the impact force transmitted to the first support frame 21 can be decomposed into a component force along the extension direction of the middle section 211, or can be through the elastic deformation of the middle section 211, so that the impact and vibration transmitted from the frame 200 to the thermal management device 100 can be greatly attenuated to ensure that the thermal management device 100 can operate normally.

[0054] In addition, a first mounting structure may also be provided on the first connecting portion 212 and extend in the front-to-back direction so that the component force along the extension direction of the middle section 211 can be decomposed into a component force along the front-to-back direction. In short, the impact force transmitted from the frame 200 to the first support frame 21 can be decomposed multiple times to reduce the impact and vibration received by the thermal management device 100.

[0055] like Figures 1 to 7As shown, in some embodiments of the present invention, in the orthographic projection along the up and down direction, the first connection portion 212 may be closer to the refrigerant plate 10 than the second connection portion 213. It can be understood that the middle section 211 extends along the up and down direction, one end of the middle section 211 is connected to the first connection portion 212, and the other end is connected to the second connection portion 213, so that there is a certain angle between the middle section 211 and the up and down direction. When the vehicle is subjected to impact and vibration, the impact force exerted on the frame 200 can be transmitted to the first support frame 21 along the front and rear direction, and then a component force along the extension direction of the middle section 211 can be decomposed, and the component force is smaller than the impact force. Therefore, the impact and vibration exerted on the thermal management device 100 can be reduced, and the reliability requirements of the thermal management device 100 for resisting impact and vibration can be met.

[0056] like Figures 1 to 7 As shown, in some embodiments of the present invention, in the orthographic projection along the front-to-back direction, the second connection portion 213 can be offset from the refrigerant plate 10 to optimize the transmission path of the impact force, thereby reducing the impact on the thermal management device 100.

[0057] In detail, the first mounting structure on the second connection part 213 can be connected to the frame 200 along the front-to-back direction so that the impact force can be transmitted from the frame 200 to the second connection part 213 along the front-to-back direction. At this time, the second connection part 213 can be staggered in the positive projection of the refrigerant plate 10 along the front-to-back direction, so that the first connection part 212 can be staggered with the second connection part 213 in the projection along the front-to-back direction. In the process of the impact force being transmitted from the frame 200 to the refrigerant plate 10, the impact force can form a component force along the extension direction of the middle section 211 on the first support frame 21. This component force is smaller than the impact force, thereby reducing the impact on the thermal management device 100.

[0058] In addition, when the vehicle is subjected to vibration or impact, the impact force can be transmitted from the frame 200 to the first support frame 21 along the front-to-back direction. During this process, the first support frame 21 can undergo elastic deformation within a certain range, that is, the first connection part 212 is displaced relative to the second connection part 213 along the front-to-back direction. At this time, in the orthographic projection along the front-to-back direction, the second connection part 213 can be misaligned with the refrigerant plate 10, so as to provide a certain displacement space for the second connection part 213, so that the first support frame 21 can better achieve the buffering effect.

[0059] like Figure 1As shown, in some embodiments of the present invention, the first connecting portion 212 can be stacked and connected to the side of the refrigerant plate 10. It can be understood that the refrigerant plate 10 can have a first plate portion and a second plate portion opposite to each other in the up and down directions, and the first plate portion and the second plate portion can both provide space for the installation of thermal management components. Therefore, the first connecting portion 212 can be connected to the side of the refrigerant plate 10, so that the first support frame 21 can avoid the thermal management components to ensure the stable connection of the components in the thermal management device 100. At the same time, the first connecting portion 212 can be stacked on the side of the refrigerant plate 10 to increase the contact area between the first support frame 21 and the refrigerant plate 10, thereby improving the connection stability of the first support frame 21 and the refrigerant plate 10. For example, a mounting hole can be set on the first connecting portion 212, and a mounting hole can be set on the corresponding side of the refrigerant plate 10. The first connecting portion 212 can be installed on the side of the refrigerant plate 10 by bolts.

[0060] like Figures 1 to 7 As shown, in some embodiments of the present invention, the first connection portion 212 and the second connection portion 213 may be perpendicular to the front-to-back direction, and the middle section 211 and the first connection portion 212 and the second connection portion 213 may have an angle greater than 90°. This arrangement can greatly reduce the impact force on the thermal management device 100, so that the thermal management device 100 meets the reliability requirements of shock and vibration resistance.

[0061] When the vehicle is subjected to impact and vibration, the impact force can be transmitted from the vehicle frame 200 to the first support frame 21. In the process of the impact force being transmitted from the second connecting portion 213 to the middle section 211, the impact force can be decomposed into a first component force along the extension direction of the middle section 211. Subsequently, in the process of the first component force being transmitted from the middle section 211 to the first connecting portion 212, the first component force can be decomposed into a second component force toward the refrigerant plate 10. At this time, the second component force is much smaller than the impact force, thereby reducing the impact and vibration received by the thermal management device 100.

[0062] Of course, the middle section 211 and the first connection part 212 and the second connection part 213 may have an angle less than 90°, so that in the process of the impact force being transmitted from the second connection part 213 to the middle section 211, the impact force can be decomposed into a first component force along the extension direction of the middle section 211, and then in the process of the first component force being transmitted from the middle section 211 to the first connection part 212, the first component force can be decomposed into a second component force toward the refrigerant plate 10. In other words, in the process of the impact force being transmitted to the first support frame 21, the second component force formed after multiple decompositions is smaller than the original impact force, thereby reducing the impact and vibration received by the thermal management device 100.

[0063] like Figures 1 to 7 As shown, in some embodiments of the present invention, the second support frame 22 may include a third connection portion 221 and a fourth connection portion 222 .

[0064] Among them, the third connection part 221 can be connected to the refrigerant plate 10, the fourth connection part 222 can be used to connect to the frame 200, and the second mounting structure can be arranged on the fourth connection part 222 and extend in the up and down directions. Therefore, the second support frame 22 can improve the impact resistance of the thermal management device 100 in the up and down directions to meet the reliability requirements of impact resistance and vibration.

[0065] Specifically, the second mounting structure extends in the up-down direction, so that the second mounting structure and the vehicle frame 200 can be connected in the up-down direction, thereby improving the connection strength between the thermal management device 100 and the vehicle frame 200 in the up-down direction, thereby improving the impact resistance of the thermal management device 100 in the up-down direction. In addition, when the vehicle is impacted in the up-down direction, the second support frame 22 can be used for buffering transition to reduce the impact and vibration of the thermal management device 100.

[0066] According to actual conditions, a second mounting structure may also be provided on the third connection portion 221 to improve the connection strength between the second support frame 22 and the refrigerant plate 10 , thereby improving the impact resistance of the thermal management device 100 .

[0067] like Figures 1 to 7 As shown, in some embodiments of the present invention, the third connection portion 221 is stacked and connected to the side of the refrigerant plate 10. It can be understood that the refrigerant plate 10 has a first plate portion and a second plate portion opposite to each other in the up and down directions. The first plate portion and the second plate portion can provide installation space for the thermal management component. Therefore, the third connection portion 221 can be connected to the side of the refrigerant plate 10, so that the second support frame 22 can avoid the thermal management component to ensure the stable connection of the components in the thermal management device 100. At the same time, the third connection portion 221 can be stacked on the side of the refrigerant plate 10 to increase the contact area between the second support frame 22 and the refrigerant plate 10, thereby improving the connection stability between the second support frame 22 and the refrigerant plate 10.

[0068] In addition, the third connection portion 221 may extend in the up-down direction and form a plate surface opposite to the side surface of the refrigerant plate 10 , so as to achieve a stacked connection between the third connection portion 221 and the side surface of the refrigerant plate 10 .

[0069] like Figures 1 to 8As shown, in some embodiments of the present invention, the refrigerant plate 10 may include a first side portion 12 and a second side portion 13 opposite to each other along the front and rear, a first support frame 21 is connected to the first side portion 12 of the refrigerant plate 10, and a second support frame 22 is connected to the second side portion 13 of the refrigerant plate 10. It can be understood that the first support frame 21 and the second support frame 22 are connected to the refrigerant plate 10 along the front and rear directions. The structural strength of the refrigerant plate 10 along the front and rear directions can be improved by the first support frame 21 and the second support frame 22, and impact buffering can be performed by the first support frame 21 and the second support frame 22, thereby improving the impact resistance of the thermal management device 100 in the front and rear directions.

[0070] In addition, there are many ways to set the support frame 20. For example, in the direction from front to back, the first side portion 12 and the second side portion 13 are arranged in sequence, that is, the first support frame 21 and the second support frame 22 are arranged in sequence from the front to the back; for another example, in the direction from front to back, the second side portion 13 and the first side portion 12 are arranged in sequence, that is, the second support frame 22 and the first support frame 21 are arranged in sequence from the front to the back; unless otherwise specified, the following description is based on the example that the first side portion 12 and the second side portion 13 are arranged in sequence from front to back.

[0071] like Figures 1 to 4 As shown, in some embodiments of the present invention, both left and right ends of the first side portion 12 of the refrigerant plate 10 can be connected to the first support frame 21, and both left and right ends of the second side portion 13 of the refrigerant plate 10 can be connected to the second support frame 22. In other words, two first support frames 21 and two second support frames 22 can be respectively provided on the refrigerant plate 10. Through these support frames 20, the installation stability of the refrigerant plate 10 on the frame 200 can be improved, so that the refrigerant plate 10 is evenly stressed.

[0072] In addition, according to different installation environments of different vehicles, the installation positions of the first support frame 21 and the second support frame 22 on the thermal management device 100 and / or the vehicle frame 200 can be changed to improve the applicability of the support frame 20 .

[0073] like Figures 1 to 7 As shown, in some embodiments of the present invention, the thermal management device 100 may further include a first buffer component 214 and a second buffer component 223 .

[0074] The first buffer component 214 can be arranged on the first support frame 21 and can cooperate with the first mounting structure. The second buffer component 223 can be arranged on the second support frame 22 and can cooperate with the second mounting structure; wherein, the radial dimension of the first buffer component 214 may not be larger than the radial dimension of the second buffer component 223; and / or, the axial dimension of the first buffer component 214 may not be larger than the axial dimension of the second buffer component 223. Such an arrangement can meet the impact resistance requirements of the thermal management device 100 in different directions.

[0075] Specifically, through force calculation, it can be concluded that the impact of the thermal management device 100 along the front-to-back direction may not be greater than the impact along the up-down direction. Therefore, it can be inferred that the radial dimension of the first buffer component 214 may not be greater than the radial dimension of the second buffer component 223, and / or that the axial dimension of the first buffer component 214 may not be greater than the axial dimension of the second buffer component 223.

[0076] It should be noted that the buffer assembly can be arranged between the support frame 20 and the frame 200. When the frame 200 vibrates, the frame 200 can be relatively displaced with the support frame 20, so that the buffer assembly is squeezed and deformed to absorb the energy of vibration and impact, thereby achieving the buffering effect of the buffer assembly. In addition, except for the axial dimension and the radial dimension, the other structural dimensions of the first buffer assembly 214 and the second buffer assembly 223 are the same.

[0077] In detail, the axial dimension of the first buffer component 214 may not be larger than the axial dimension of the second buffer component 223, which means that when the frame 200 is subjected to impact and vibration in the front-to-back direction, the first support frame 21 may be displaced relative to the first buffer component 214, thereby causing the first buffer component 214 to be squeezed and deformed. Similarly, when the frame 200 is subjected to impact and vibration in the up-down direction, the second support frame 22 may be displaced relative to the second buffer component 223, thereby causing the second buffer component 223 to be squeezed and deformed. In general, the impact and vibration received by the second buffer component 223 may be smaller than the impact and vibration received by the first buffer component 214. Therefore, the axial dimension of the first buffer component 214 undergoing squeezing and deformation may not be larger than the axial dimension of the second buffer component 223 undergoing squeezing and deformation, so as to meet the impact resistance requirements of the thermal management device 100 in different directions.

[0078] In addition, by increasing the radial dimension of the first buffer component 214, the contact area between the first buffer component 214 and the frame 200 and the first support frame 21 can be increased, thereby improving the buffering effect of the first buffer component 214; similarly, by increasing the radial dimension of the second buffer component 223, the contact area between the second buffer component 223 and the frame 200 and the second support frame 22 can be increased, thereby improving the buffering effect of the second buffer component 223. Therefore, according to the reliability requirements of the vibration of the thermal management device 100 in the up and down directions and the front and back directions, the radial dimension of the first buffer component 214 is not greater than the radial dimension of the second buffer component 223.

[0079] On the contrary, the first buffer component 214 and the second buffer component 223 can attenuate the vibration generated by the thermal management device 100 to prevent the vibration from being transmitted to the interior of the vehicle and causing noise inside the vehicle. It can be understood that a thermal management component such as a water pump can be installed on the refrigerant plate 10. The water pump can drive the refrigerant flow in the refrigerant flow channel 11 on the refrigerant plate 10 to achieve vehicle temperature control. During this process, the water pump will generate vibration when working, and the vibration can be transmitted to the frame 200 through the first support frame 21 and the second support frame 22. At this time, the first buffer component 214 and the second buffer component 223 can respectively buffer the first support frame 21 and the second support frame 22, thereby attenuating the vibration generated by the thermal management device 100 and improving the NVH performance of the vehicle.

[0080] Further, the fourth connecting portion 222 may include a first portion, a second portion and a third portion, the third portion may be connected to the first portion, the second portion and the third connecting portion 221 respectively, and a slide groove is formed between the first portion and the second portion, the slide groove may extend in the left and right directions, and may serve as a second mounting structure, the second buffer component 223 may be arranged in the slide groove, and a bolt may be inserted through the second buffer component 223 to realize the connection between the second support frame 22 and the frame 200, wherein, in combination with the aforementioned embodiment, a second support frame 22 may be provided at the left and right ends of the second side portion 13. 2, and the slide groove in the second support frame 22 can extend in the left-right direction, a second buffer component 223 can be installed in the second mounting structure from left to right, and another second buffer component 223 can be installed in the second mounting structure from right to left. When the thermal management device 100 is fixedly connected to the frame 200, the refrigerant plate 10 can be clamped through the connection points between the two second support frames 22 and the frame 200, thereby improving the connection stability. At the same time, the second buffer component 223 can move along the slide groove to facilitate the adjustment of the assembly degree between the thermal management device 100 and the frame 200.

[0081] Furthermore, the first buffer assembly 214 and the second buffer assembly 223 may include vibration isolation pads and bushings.

[0082] Among them, the vibration isolation pad is sleeved on the outside of the bushing. Through the cooperation of the vibration isolation pad and the bushing, the buffering effect of the buffer assembly can be realized, and the axial dimension of the bushing can be smaller than the axial dimension of the vibration isolation pad. This arrangement can make the vibration isolation pad within a recoverable deformation range to reduce damage to the buffer assembly.

[0083] Specifically, when the vehicle frame 200 is subjected to impact and vibration, it may be relatively displaced with the first support frame 21. At this time, the vibration isolation pad in the first buffer assembly 214 may be squeezed and deformed along its own axial direction, wherein the axial direction of the vibration isolation pad in the first buffer assembly 214 may be in the same direction as the front-to-back direction. When the vibration isolation pad is deformed axially by a predetermined distance, the frame 200 may abut against the end of the bushing, thereby preventing the vibration isolation pad from continuing to be squeezed and deformed, so as to avoid the vibration isolation pad from being deformed too much and unable to recover. Similarly, when the vehicle frame 200 is subjected to impact and vibration, it may be relatively displaced with the second support frame 22. At this time, the vibration isolation pad in the second buffer assembly 223 may be deformed along its own axial direction, wherein the axial direction of the vibration isolation pad in the second buffer assembly 223 may be in the same direction as the up-down direction. When the vibration isolation pad is deformed axially by a predetermined distance, the frame 200 may abut against the end of the bushing, thereby preventing the vibration isolation pad from continuing to be squeezed and deformed, so as to avoid the vibration isolation pad from being deformed too much and unable to recover.

[0084] In addition, in combination with the aforementioned embodiment, the first mounting structure may be a first mounting hole, and a corresponding third mounting hole is also provided on the frame 200. The first support frame 21 may be connected to the frame 200 by bolts, and the bolts may be sleeved on the inner side of the bushing so that the buffer assembly is stably connected between the support frame 20 and the frame 200.

[0085] like Figures 1 to 7 As shown, in some embodiments of the present invention, the support frame 20 may be provided with reinforcing ribs 40 , and the reinforcing ribs 40 may extend in the same direction as the support frame 20 to improve the structural strength of the support frame 20 .

[0086] In detail, a first reinforcing rib 40 may be provided in the first support frame 21, wherein the extension direction of the first reinforcing rib 40 may be the same as the extension direction of the middle section 211, and the two ends of the first reinforcing rib 40 may extend to the first connection portion 212 and the second connection portion 213 respectively, thereby improving the overall structural strength of the first support frame 21, so as to improve the impact resistance of the thermal management device 100. A second reinforcing rib 40 may be provided in the second support frame 22, wherein the extension direction of the second reinforcing rib 40 may be the same as the extension direction of the third connection portion 221, that is, extending in the up-down direction, and part of the second reinforcing rib 40 may cross the connection position between the third connection portion 221 and the fourth connection portion 222, so as to extend to the fourth connection portion 222, thereby improving the structural strength of the second support frame 22, and realizing the improvement of the impact resistance of the thermal management device 100.

[0087] like Figures 1 to 4As shown, in some embodiments of the present invention, a plurality of support frames 20 are arranged at intervals along the circumference of the refrigerant plate 10. In other words, a plurality of support frames 20 may be respectively provided around the circumference of the thermal management device 100 to increase the number of connection positions between the thermal management device 100 and the frame 200, thereby improving the connection stability between the thermal management device 100 and the frame 200.

[0088] like Figures 1 to 7 As shown, in some embodiments of the present invention, the plurality of support frames 20 may further include a third support frame 30 for installing a heater 50, and the third support frame 30 may be respectively connected to a first support frame 21 and a second support frame 22, and the third support frame 30 is connected to the heater 50 in a stacked manner. It can be understood that by using the first support frame 21 and the second support frame 22 connected to the refrigerant plate 10, an installation position is provided for the thermal management components of the thermal management device 100, thereby improving the applicability of the support frame 20; specifically, a third support frame 30 may be provided on the refrigerant plate 10, and the third support frame 30 may be respectively connected to a first support frame 21 and a second support frame 22, and then the heater 50 may be installed on the refrigerant plate 10 through the third support frame 30, and therefore, the installation of thermal management components (for example, wiring harness components, etc.) may be achieved through the first support frame 21 and the second support frame 22.

[0089] In some embodiments of the present invention, the first mounting structure may be a positioning hole or a positioning column, and the second mounting structure may be a positioning hole or a positioning column. In other words, by cooperating with the first mounting structure and the second mounting structure and the frame, the connection strength of the thermal management device 100 on the frame can be improved, thereby improving the impact resistance of the thermal management device 100.

[0090] For example, the first mounting structure may be a first positioning hole, and a corresponding third positioning hole may be provided on the frame, and the first positioning hole and the third positioning hole may be threadedly connected by bolts; for another example, the second mounting structure may be a second positioning hole, and a corresponding fourth positioning hole may be provided on the frame, and the second positioning hole and the fourth positioning hole may be connected by bolts. In other words, the first mounting structure and the second mounting structure are respectively threadedly connected to the frame.

[0091] For another example, the first mounting structure and the second mounting structure may be positioning columns, and corresponding through holes may be provided on the vehicle frame. The connection between the first mounting structure, the second mounting structure and the vehicle frame is achieved by inserting the positioning columns into the through holes and locking them with locking members. The connection methods between the first mounting structure, the second mounting structure and the vehicle frame in the present invention include but are not limited to the aforementioned embodiments.

[0092] like Figure 3 and Figure 4As shown, according to the vehicle in the embodiment of the present invention, the vehicle may include a frame 200 and the thermal management device 100 in the above embodiment, and the thermal management device 100 is arranged on the frame 200. By applying the aforementioned thermal management device 100, the normal operation of the thermal management device 100 can be guaranteed, so as to improve the temperature control effect of the thermal management device 100 on the vehicle and improve the user experience.

[0093] The first mounting structure extends in the front-to-back direction, so that the second connection portion 213 can be connected to the frame 200 in the front-to-back direction. In other words, the impact force can be transmitted from the frame 200 to the second connection portion 213 in the front-to-back direction. The second mounting structure extends in the up-down direction, so that the fourth connection portion 222 can be connected to the frame 200 in the up-down direction. In other words, the impact force can be transmitted from the frame 200 to the fourth connection portion 222 in the up-down direction.

[0094] Specifically, the first support frame 21 includes a middle section 211, a first connecting portion 212 and a second connecting portion 213. The first connecting portion 212 is connected to the refrigerant plate 10, and the second connecting portion 213 is connected to the vehicle frame 200. The first connecting portion 212 and the second connecting portion 213 are both perpendicular to the front-to-back direction. The middle section 211 gradually tilts backward from top to bottom, so when the vehicle is subjected to impact vibration, the impact force can first be transmitted to the second connecting portion 213 along the front-to-back direction, and can be decomposed into a first component force along the extension direction of the middle section 211, and then a second component force along the front-to-back direction can be decomposed again, thereby reducing the impact force on the refrigerant plate 10.

[0095] Furthermore, a first buffer component 214 may be provided on the second connection portion 213. The first buffer component 214 is arranged in the first mounting structure. When the frame 200 is vibrated, the frame 200 and the first support frame 21 may approach or move away from each other in the front-to-back direction to squeeze the first buffer component 214. In other words, buffering by the first buffer component 214 can attenuate the vibration transmitted from the frame 200 to the first support frame 21, so as to meet the reliability requirements of the vibration of the thermal management device 100 in the front-to-back direction.

[0096] Similarly, the two second support frames 22 can be respectively connected to the two ends of the second side portion 13, wherein the second support frame 22 includes a third connection portion 221 and a fourth connection portion 222, the third connection portion 221 is connected to the refrigerant plate 10, and the fourth connection portion 222 is connected to the frame 200, and the fourth connection portion 222 is provided with a second mounting structure, and the second mounting structure and the frame 200 can be connected in the up and down direction to improve the connection strength between the refrigerant plate 10 and the frame 200 in the up and down direction, thereby improving the impact resistance of the thermal management device 100 in the up and down direction.

[0097] Furthermore, a second buffer component 223 may be provided on the fourth connecting portion 222, and the second buffer component 223 is arranged in the second mounting structure. When the frame 200 is vibrated, the frame 200 and the second support frame 22 may approach or move away from each other in the up and down directions to squeeze the second buffer component 223. In other words, buffering by the second buffer component 223 can attenuate the vibration transmitted from the frame 200 to the second support frame 22, so as to meet the reliability requirements of the vibration of the thermal management device 100 in the up and down directions.

[0098] Furthermore, a first reinforcing rib 40 may be provided on the first support frame 21, and the reinforcing rib 40 is in the same direction as the extension direction of the middle section 211 of the first support frame 21, and can extend to the first connection portion 212 and the second connection portion 213, so as to improve the structural strength of the first support frame 21. Similarly, a second reinforcing rib 40 may be provided on the second support frame 22, and the second reinforcing rib 40 is in the same direction as the extension direction of the third connection portion 221 of the second support frame 22, and can extend to the fourth connection portion 222, so as to improve the structural strength of the second support frame 22. In general, by providing reinforcing ribs 40 on the first support frame 21 and the second support frame 22, the impact resistance of the thermal management device 100 in the front-to-back direction and the up-and-down direction can be improved, so as to meet the impact requirements of the thermal management device 100.

[0099] In addition, the first connection part 212 and the third connection part 221 can be stacked and connected on the side of the refrigerant plate 10 to increase the contact area between the first support frame 21 and the second support frame 22 and the refrigerant plate 10, and improve the connection strength between the support frame 20 and the refrigerant plate 10. At the same time, the thermal management components installed on the refrigerant plate 10 can be avoided to facilitate the installation of the thermal management components.

[0100] In some specific examples of the present invention, the supporting assembly (i.e., the supporting frame 20) of the thermal management integrated module (i.e., the thermal management device 100) adopts four independent supporting structures. In order to meet the reliability requirements of the integrated module in terms of impact resistance and vibration, the supporting frame 20 is fixedly connected to the refrigerant plate 10 in the integrated module (to meet the impact resistance requirements).

[0101] At the same time, the frame 200 uses vibration reduction components (i.e., buffer components) of different sizes in the X direction (front and rear direction of the vehicle body) and the Z direction (up and down direction of the vehicle body), and the overall diameter and height of the X-direction vibration reduction component are not greater than those of the Z-direction vibration reduction component.

[0102] The support assembly itself serves as a mounting bracket for the thermal management integrated module and can also provide mounting points for the water heater 50, wiring harness, liquid reservoir, etc.

[0103] Usually in the automotive thermal management system, the thermal management integration and the assembly of the whole vehicle are usually hard-connected by directly installing the refrigerant plate 10 or the water side plate, and the assembly method is relatively cumbersome, the intermediate integration interchangeability is low, the vibration isolation effect is poor, and the cost is high. However, the support frame 20 in the thermal management device 100 of the present invention can improve the vibration isolation effect between the thermal management device 100 and the frame 200, and the assembly method is simple, and the connection position of the support frame 20 can be changed according to different needs to meet the impact resistance requirements.

[0104] The present invention discloses an automotive thermal management integrated module (i.e., a thermal management device 100), which includes at least two or more components of a water side component, a refrigerant side component, a support buffer component, a wiring harness component, and a water heater 50. The water side component may include two or more components of a kettle, a flow channel plate, a water valve, a water pump, a water temperature sensor, a heat exchanger, etc. The refrigerant side component includes two or more components of a refrigerant plate 10, a valve device, a temperature sensor, a pressure sensor, a gas-liquid separator (referred to as gas separation), a liquid storage device, and various types of heat exchangers. The support buffer component includes two or more components of a support frame 20, a vibration isolation pad, a bushing, etc.

[0105] The thermal management device 100 may include a refrigerant circuit and a coolant circuit. The coolant circuit and the refrigerant circuit are each closed-loop circulated and heat exchanged through a plate heat exchanger, thereby achieving effective temperature control of the vehicle battery, electric drive and passenger compartment. The internal components of the thermal management device 100 can selectively adopt solutions with or without electronic control, combined with an integrated controller to achieve a lower-cost overall solution. The integrated module of the present invention greatly reduces the overall size of the thermal management system, achieving miniaturization and lightweight of the system. At the same time, due to the heat exchange between the two side circuits, the energy utilization rate of the vehicle is improved.

[0106] In the refrigerant side component, the refrigerant plate 10 is used as the base, and the valve device, liquid reservoir or gas-liquid separator and heat exchanger are connected to the external flow channel of the refrigerant plate 10, and are relatively fixed and sealed on the refrigerant plate 10. A refrigerant flow channel 11 is also provided inside the refrigerant plate 10, which is used to connect the valve devices and other vehicle thermal management components (such as compressors, front-end modules, air conditioning boxes, etc.). At the same time, the refrigerant plate 10 and the heat exchanger include interfaces that are directly connected or indirectly connected to the other thermal management components of the vehicle (indirect connection refers to connecting to the outside through a short refrigerant pipe). The refrigerant side circuit is formed by the interfaces, channels, valve devices, liquid reservoirs or gas-liquid separators, heat exchangers and other thermal management components of the vehicle. The refrigerant side component includes multiple heat exchangers with different functions, such as a battery cooler, a battery heater, a water-to-water heat exchanger, a heat pump, and a water-cooled cooler. Sensors are arranged in some flow channels of the regenerator loop to monitor the temperature or pressure of the fluid in the required flow channel (the sensor channel may not be in the flow channel, and a separate sensor channel may be opened to measure the temperature or pressure at that point).

[0107] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0108] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
