[0017] The following further describes specific embodiments with reference to the accompanying drawings.
[0018] Please refer to Figures 1-3 , Figure 1 which is a schematic structural diagram of the heat exchange device according to an embodiment of the present invention; Figure 2 is Figure 1 a schematic structural diagram of the fixing device in Figure 3 is Figure 2 a schematic structural diagram of the structure without the shock absorption washer in
[0019] This embodiment provides a heat exchange device. As shown in Figure 1 , the heat exchange device includes a fixing bracket and a heat exchange core 3. The fixing bracket can mount the heat exchange device on an electric vehicle body. As shown in Figures 1-3 , the fixing bracket includes a bottom plate part 1 and at least two suspension parts 2. Among them, the bottom plate part 1 and the heat exchange core 3 can be fixed by welding or other means. The suspension part 2 includes a first connecting part 21 and a mounting part 23. The first connecting part 21 is located between the bottom plate part 1 and the mounting part 23, and the mounting part 23 can be fixed to the electric vehicle body by screws or other means, thereby fixing the heat exchange device to the electric vehicle body.
[0020] After fixing the heat exchange core 3 to the bottom plate portion 1, it is fixed to the electric vehicle body through at least two suspension portions 2, which can improve the structural strength of the fixing bracket. For the same heat exchange core 3 (the load-bearing of the fixing bracket is the same), since at least two suspension portions 2 bear the torque, it can ensure that the fixing bracket can stably fix the heat exchange core 3 to the electric vehicle body, and at the same time, the strength requirements and material requirements for a single suspension portion 2 can be reduced, its volume (such as thickness or thickness, etc.) can be reduced, the weight can be reduced and the cost can be reduced. At the same time, in a relatively harsh three-dimensional installation space, it is convenient to install the fixing bracket.
[0021] In this embodiment, there is no specific requirement for the number of suspension portions 2. For example, Figures 1-3 As shown, the number of suspension portions 2 is two, and it can also be three or more. Specifically, it can be set according to the actual installation space, the weight of the heat exchange core 3, etc.
[0022] In the above embodiment, there is also a second connecting portion 22 between the mounting portion 23 and the first connecting portion 21. The heat exchange core 3 has a first outer portion 31 and a second outer portion 32. The first outer portion 31 and the second outer portion 32 are respectively perpendicular to the bottom plate portion 1, and the first outer portion 31 and the second outer portion 32 are also perpendicular to each other. The first connecting portion 21 protrudes from the bottom plate portion 1 along the first outer portion 31, the second connecting portion 22 protrudes from the first connecting portion 21 along the second outer portion 32, and the mounting portion 23 protrudes from the second connecting portion 22 along the direction perpendicular to the second outer portion 32. The height that the second connecting portion 22 protrudes from the first connecting portion 21 can be adjusted according to the width of the second outer portion 32, so that the mounting portion 23 is closer to the centroid position of the heat exchange core 3, thereby strengthening the strength of the suspension portion 2 to withstand pressure and enhancing the structural strength of the fixing bracket itself.
[0023] It should be noted here that "perpendicular" does not refer to the completely mathematical perpendicular, but also includes approximately perpendicular, having a perpendicular trend, etc. In the above embodiment, the suspension portion 2 further includes a third connecting portion 24 connected between the mounting portion 23 and the bottom plate portion 1. The third connecting portion 24 is provided on the side of the first connecting portion 21 facing the bottom plate portion 1, and the third connecting portion 24 protrudes from the mounting portion 23 in the direction perpendicular to the second outer portion 32. The third connecting portion 24 is fixedly or limitedly provided with the bottom plate portion 1.
[0024] One end of the mounting portion 23 is connected to the bottom plate portion 1 through the first connecting portion 21 and the second connecting portion 22, and the other end of the mounting portion 23 is connected to the bottom plate portion 1 through the third connecting portion 24, that is, both ends of the suspension portion 2 are connected and fixed to different positions of the bottom plate portion 1, thereby further enhancing the overall structural strength of the suspension portion 2 and enhancing the connection stability between the heat exchange core 3 and the electric vehicle body.
[0025] Furthermore, the bottom plate portion 1 is also provided with a mating groove 11 adapted to the end of the third connecting portion 24. The end of the third connecting portion 24 is fixedly connected within the mating groove 11, and specifically, it can be fixed by welding, riveting, or bolting, etc. The end of the third connecting portion 24 is fixedly connected within the mating groove 11, so that when the end of the third connecting portion 24 is fixed to the mating groove 11, the surface height difference between the third connecting portion 24 and the bottom plate portion 1 is small. A part of the second connecting portion 22, the bottom plate portion 1, and the heat exchange core 3 can be fixedly installed by welding, and at the same time, interference with other structures of the electric vehicle body can be avoided, ensuring smooth and stable installation. Moreover, since the upper surface of the bottom plate portion 1 is flat, the contact area between it and the heat exchange core 3 can be increased, so that when the heat exchange core 3 is fixedly welded to the bottom plate portion 1, the welding can be more firm.
[0026] In the above-mentioned present embodiment, the suspension portion 2 is an integral structure, and the above-mentioned first connecting portion 21, mounting portion 23, second connecting portion 22, and third connecting portion 24 are formed through the bending portion. Alternatively, the first connecting portion 21, second connecting portion 22, mounting portion 23, and third connecting portion 24 can also be set as independent structures and fixedly connected in sequence by welding or other means. In this embodiment, the setting of the integral structure can simplify the overall structure and the processing technology, and can also improve the stability of the fixing bracket.
[0027] The side of the bottom plate portion 1 extends and bends outward to form the above-mentioned suspension portion 2. There is a first bending portion 25 between the bottom plate portion 1 and the first connecting portion 21. Alternatively, the end of the first connecting portion 21 of the suspension portion 2 and the bottom plate portion 1 can also be fixed by fixing means such as welding, riveting, or bolting. In this embodiment, the bottom plate portion 1 and the suspension portion 2 being an integral structure can simplify the overall structure and the processing technology, and can also improve the stability of the fixing bracket.
[0028] As Figure 2 and Figure 3 shown, the extension portion is provided with a first bending portion 25 at the side of the bottom plate portion 1 to form the first connecting portion 21, then forms the second connecting portion 22 through the second bending portion 26, then forms the mounting portion 23 through the third bending portion 27, and finally forms the third connecting portion 24 through the fourth bending portion 28.
[0029] In the above-mentioned embodiment, reinforcing ribs 4 can be provided on each bending portion. In this embodiment, the above-mentioned first bending portion 25, second bending portion 26, third bending portion 27, and fourth bending portion 28 can all be provided with reinforcing ribs 4 to ensure the structural strength of the suspension portion 2 and the connection strength between the suspension portion 2 and the bottom plate portion 1.
[0030] In addition, in this embodiment, the angles of the bending parts are not limited. In this embodiment, the angles of the bending parts are all 90°, or they can also be set to other angles, which can be specifically set according to the actual installation situation.
[0031] In the above embodiment, the bottom plate part 1 is provided with a weight-reducing hole 12, and the weight-reducing hole 12 is located in the middle of the bottom plate part 1. In this way, the weight of the bottom plate part 1 can be reduced, and further the overall structure of the fixing bracket can be made lighter, reducing the cost.
[0032] In the above embodiment, the bottom plate part 1 and the heat exchange core 3 are respectively provided with positioning structures that match each other, such as Figure 2 and Figure 3 As shown, the bottom plate part 1 is provided with a positioning hole 13. Correspondingly, the heat exchange core 3 is provided with a positioning structure that matches the positioning hole 13. Or, it can also be that the bottom plate part 1 is provided with a positioning structure and the heat exchange core 3 is provided with a positioning hole 13. There is no specific limitation here. The setting of the positioning structure facilitates quickly finding the installation position of the bottom plate part 1 and improves the installation efficiency.
[0033] In the above embodiment, as Figure 1 shown, the fixing bracket further includes an auxiliary installation part 5. The auxiliary installation part 5 is arranged on the side of the heat exchange core 3 away from the bottom plate part 1 and can be fixed to the heat exchange core 3 by means of welding, screws, etc. The auxiliary installation part 5 and the bottom plate part 1 can be respectively located on opposite sides of the heat exchange core 3, so that it can be stably installed on the electric vehicle body. Specifically, there is no limitation on the specific structure of the auxiliary installation part 5. For example, it can be set as a flat plate structure, or provided with a bending part, or provided with a weight-reducing hole 12, etc.
[0034] In the above embodiment, both the installation part 23 and the above-mentioned auxiliary installation part 5 are provided with installation holes 6 for connecting to the electric vehicle body through bolts, etc. Specifically, the inner wall of the installation hole 6 is provided with a shock-absorbing washer 61. In the installation state, the rigid collision between the bolt and the inner wall of the installation hole 6 can be reduced, thereby reducing the vibration of the heat exchange core 3 and avoiding damage caused by vibration, and prolonging the service life of the heat exchange core 3.
