[0002] Autopilot is the key technology to realize intelligent vehicles and intelligent transportation, and it is also an inevitable trend in the future development of vehicles. From the perspective of industrial development, autopilot will become an important engine for the development of many future industries through the integration with the Internet of Things, cloud computing, and artificial intelligence, and will drive the rapid development of intelligent manufacturing and new generation information technology.

[0003] The computing device is the brain of the entire autopilot system. With the continuous improvement of the autopilot level, the demand for the computing power of in-vehicle computing devices is increasing, and thus the requirement for heat dissipation is higher. The liquid cooling heat exchange device can effectively dissipate heat from the heat-generating components, thereby solving the problem of difficult heat dissipation. The liquid cooling heat exchange device usually includes a flow channel plate, a cover plate, and a water nozzle. The flow channel plate is provided with heat exchange channels, the cover plate covers the flow channel plate, and the water nozzle is installed on the flow channel plate.

[0004] The problem is that the water nozzle is usually installed on the flow channel plate by brazing, and the water nozzle is prone to displacement, poor welding and other phenomena during the brazing process. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a flow channel plate, a heat exchange device and an intelligent vehicle, so as to solve to a certain extent the technical problem that the water nozzle is prone to displacement, poor welding and other phenomena during the brazing process in the prior art.

[0006] The utility model provides a flow channel plate, comprising: a plate body, wherein the plate body is provided with a connection hole; a limiting member, which is arranged on the plate body; a circulation nozzle, which is communicated with the connection hole; and a matching member, which is arranged on the circulation nozzle, and the limiting member is connected with the matching member.

[0007] The limiting member is arranged on the plate body, and the matching member is arranged on the circulation nozzle. The limiting member can be connected with the matching member. Before welding the circulation nozzle to the plate body, the limiting member and the matching member are first connected, so that the circulation nozzle can be pre-limited and fixed on the plate body, and then the circulation nozzle is welded to the plate body. By matching the limiting member and the matching member to limit the circulation nozzle, the displacement of the circulation nozzle during the welding process can be avoided, the positional accuracy of the circulation nozzle can be guaranteed, the risk of poor welding can be reduced, and thus the welding effect of the circulation nozzle can be guaranteed to be good.

[0008] Further, the limiting member and the matching member are snap-connected.

[0009] The snap connection between the limiting member and the matching member facilitates the connection between the limiting member and the matching member.

[0010] Furthermore, the limiting member includes a clamping plate, and a plurality of the clamping plates are arranged at intervals along the circumferential direction of the connecting hole; the clamping plate includes a connecting section and a bending section that are connected to each other and arranged at an angle, and the connecting section is fixedly connected to the plate body; the cooperating member includes a cooperating protrusion, and the bending section is connected to a side of the cooperating protrusion away from the plate body.

[0011] Furthermore, the cooperating protrusion is an annular cooperating protrusion extending along the circumferential direction of the flow nozzle.

[0012] The cooperating protrusion is an annular cooperating protrusion. Align the flow nozzle with the connecting hole and bend the bending section to the annular cooperating protrusion, without specifically corresponding one cooperating protrusion to one clamping plate, which is more convenient for assembly.

[0013] As an alternative solution, a notch is provided on the cooperating protrusion, and the connecting section can be clamped in the notch.

[0014] With such a setting, not only can the bending section limit the flow nozzle, but also the flow nozzle can be limited through the notch, further ensuring the positional accuracy of the flow nozzle and being more conducive to improving the welding yield.

[0015] As another alternative solution, a limiting protrusion is provided on the cooperating protrusion, and the limiting member includes a limiting opening, and the limiting protrusion can be clamped in the limiting opening.

[0016] With such a setting, through the cooperation of the limiting protrusion and the limiting opening, the flow nozzle can be limited, which is more convenient for welding.

[0017] Furthermore, one end of the flow nozzle is inserted into the connecting hole.

[0018] Furthermore, the flow nozzle is a straight nozzle.

[0019] Furthermore, the flow nozzle is a bent nozzle.

[0020] The present utility model provides a heat exchange device, including a cover plate and the above-mentioned flow channel plate. In the thickness direction of the flow channel plate, a heat exchange flow channel is provided on the first surface of the plate body, and a heat exchange protrusion is provided on the second surface of the plate body; the cover plate covers the first surface.

[0038] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0039] Generally, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model.

[0040] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0041] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] In addition, terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0044] As Figures 1 to 7 shown, the present utility model provides a flow channel plate 100, including: a plate body 1, on which connection holes are provided; a limiting member, which is arranged on the plate body 1; a flow nozzle 2, which is communicated with the connection holes; a fitting 4, which is arranged on the flow nozzle 2, and the limiting member is connected to the fitting 4.

[0045] In this embodiment, a limiting member is provided on the plate body 1, and a mating member 4 is provided on the flow nozzle 2. The limiting member can be connected to the mating member 4. Before welding the flow nozzle 2 to the plate body 1, the limiting member is first connected to the mating member 4, so that the flow nozzle 2 can be pre-limited and fixed on the plate body 1, and then the flow nozzle 2 is welded to the plate body 1. By matching the limiting member and the mating member 4 to limit the flow nozzle 2, the displacement of the flow nozzle 2 during the welding process can be avoided, the positional accuracy of the flow nozzle 2 can be ensured, the risk of poor welding can be reduced, and thus the welding effect of the flow nozzle 2 can be ensured to be good.

[0046] Among them, the connecting hole can be provided on the plate surface of the plate body in its thickness direction or on the side wall of the plate body in its length direction and / or width direction (that is: the connecting hole is provided on the side wall of the plate body in its width direction; or, the connecting hole is provided on the side wall of the plate body in its length direction; or the connecting holes are provided on the side walls of the plate body in its length direction and in its width direction).

[0047] The structural forms of the limiting member and the mating member 4 can be various. For example: the limiting member is an internal thread provided on the inner wall of the connecting hole, and the mating member 4 is a screw rod connected to the flow nozzle 2 and communicating with the communication hole. The screw rod is provided with a hollow structure. Before welding the flow nozzle 2, the screw rod is tightened in the communication hole.

[0048] As an alternative solution, the limiting member and the mating member 4 are connected together by snap connection, which facilitates the connection between the limiting member and the mating member 4.

[0049] Among them, the limiting member can be a protrusion protruding outside the plate body 1, and the protrusion is fixed on the plate body 1; the mating member 4 includes a connecting block, and a groove is provided on the connecting block. The protrusion can be inserted into the groove; among them, the number of protrusions can be two, and the two protrusions are respectively provided on both sides of the connecting hole. Correspondingly, the number of grooves is two, and the two protrusions are respectively inserted into the two grooves one by one; or, the number of protrusions is three or more (including three), and multiple protrusions are arranged at intervals along the circumferential direction of the connecting hole on the plate body 1. Correspondingly, the number of grooves is the same as the number of protrusions.

[0050] Or, the limiting member is a metal spring piece, and multiple metal spring pieces are arranged at intervals along the circumferential direction of the connecting hole on the plate body 1. One end of the spring piece is fixed on the plate body 1, and the multiple metal spring pieces hold the flow nozzle 2 tightly, thereby limiting the flow nozzle 2.

[0051] As an alternative solution, as Figures 1 to 3As shown in the figure, the limiting member includes a clamping plate 3, and a plurality of clamping plates 3 are arranged at intervals along the circumferential direction of the connecting hole; the clamping plate 3 includes a connecting section and a bending section 31 which are connected to each other and arranged at an angle, and the connecting section is fixedly connected to the plate body 1 (the connection section can be fixed on the plate body 1 by welding, preferably, the connecting section and the plate body 1 are integrally formed, which is convenient for processing); the fitting member 4 includes a fitting protrusion 41 protruding outward from the flow nozzle 2, that is, the fitting protrusion 41 is arranged on the outer side wall of the flow nozzle 2, and the bending section 31 is connected to the side of the fitting protrusion 41 away from the plate body 1.

[0052] In this embodiment, before the flow nozzle 2 is installed on the plate body, the connecting section and the bending section 31 allow the flow nozzle 2 to be placed at the connecting hole. After the flow nozzle 2 is placed in place, the bending section 31 is bent towards the fitting protrusion 41, so that the bending section 31 is connected to the side of the fitting protrusion 41 away from the plate body 1. A plurality of bending sections 31 and the plate body 1 form a limiting groove, so as to clamp the fitting protrusion 41 in the limiting groove.

[0053] Among them, the number of the plurality of clamping plates 3 can be three, or the number of the plurality of clamping plates 3 is four, or the number of the plurality of clamping plates 3 is more, for example: five, six or seven, etc. Optionally, the plurality of clamping plates 3 are evenly distributed along the circumferential direction of the connecting hole.

[0054] On the basis of the above embodiment, the fitting protrusion 41 can be dot-shaped, and the number of the fitting protrusions 41 is multiple, and the number of the fitting protrusions 41 is the same as the number of the clamping plates 3. At this time, when installing the flow nozzle 2, it is necessary to align the fitting protrusion 41 with the clamping plate 3.

[0055] As an alternative solution, as Figure 3 and Figure 7 shown, the fitting protrusion 41 is an annular fitting protrusion 41 extending along the circumferential direction of the flow nozzle 2.

[0056] In this embodiment, the fitting protrusion 41 is an annular fitting protrusion 41. Align the flow nozzle 2 with the connecting hole, and bend the bending section 31 to the annular fitting protrusion 41, without specifically corresponding one fitting protrusion 41 to one clamping plate 3, which is more convenient for assembly.

[0057] Among them, it can be arranged in the radial direction of the annular fitting protrusion 41, and the connecting section is located outside the annular fitting protrusion 41, that is, a plurality of connecting sections surround the annular fitting protrusion 41. At this time, when installing the flow nozzle 2, place the flow nozzle 2 between the plurality of clamping plates 3.

[0058] As an alternative solution, as Figure 7 shown, the fitting protrusion 41 is also provided with a notch 42, and the connecting section can be clamped in the notch 42.

[0059] In this embodiment, during the process of installing the flow nozzle 2 onto the plate body 1, the notch 42 can be aligned with the clamping plate 3. After the clamping plate 3 passes through the notch 42, the bent section 31 can then be pressed to the side of the mating protrusion 41 away from the plate body 1. With such a setting, not only can the bent section 31 limit the position of the flow nozzle 2, but the flow nozzle 2 can also be limited by the notch 42, further ensuring the positional accuracy of the flow nozzle 2 and being more conducive to improving the welding yield.

[0060] As another alternative solution, a limiting protrusion is provided on the mating protrusion 41, and the limiting member includes a limiting opening, and the limiting protrusion can be clamped in the limiting opening.

[0061] In this embodiment, through the cooperation of the limiting protrusion and the limiting opening, the limiting of the flow nozzle can be achieved, making welding more convenient.

[0062] Among them, the limiting protrusion can extend along the length direction of the flow nozzle 2, and an opening is provided on the plate body 1 to form the limiting opening, and the limiting protrusion can be inserted into the limiting opening. Or, the limiting protrusion can be provided on the side wall of the mating protrusion 41 and extend in a direction perpendicular to the length direction of the flow nozzle 2, and a plurality of limiting members are arranged at intervals along the circumferential direction of the connecting hole 13, and the interval between two adjacent limiting members forms the limiting opening.

[0063] Based on the above embodiments, further, one end of the flow nozzle is inserted into the connecting hole. With such a setting, the connecting hole can also limit the position of the flow nozzle, further ensuring the positional accuracy of the flow nozzle and further improving the welding yield.

[0064] In some alternative solutions, after the flow nozzle is installed in place, the side of the annular protrusion close to the plate body can be used as the welding surface, and the end of the flow nozzle close to the plate body can be used as the welding surface.

[0065] Based on the above embodiments, further, the flow nozzle 2 can be a straight nozzle, and the flow nozzle can also be a bent nozzle.

[0067] In this embodiment, the cover plate 200 covers the first surface of the plate body 1, thereby sealing the heat exchange flow channel 11. Two flow nozzles 2 can be provided on the side wall of the plate body 1, one of which is an inlet nozzle 21 and the other is an outlet nozzle 22. Both the inlet nozzle 21 and the outlet nozzle 22 are communicated with the heat exchange flow channel 11, so as to realize the circulation of the heat exchange fluid.
