[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.
[0027] As Figure 1 、 Figure 2 shown, the present invention discloses a connection assembly. The connection assembly includes at least two connection structures 1. The connection structure 1 is used to connect two devices that need to be connected together, so that the medium in the previous device can flow to the latter device; at least two connection structures 1 are located in the same plane; the connection structure 1 includes a first connection area 2 and a second connection area 3 that are connected and communicated. The first connection area 2 and the second connection area 3 are located on the same straight line. The first connection area 2 is used to communicate with the outlet of the previous device, and the second connection area 3 is used to communicate with the inlet of the latter device.
[0028] The present invention connects two devices that need to be connected through the connection structure 1. The first connection area 2 and the second connection area 3 of the connection structure 1 are located on the same straight line. This means that the outlet of the previous device and the inlet of the latter device are located on the same straight line. And between two points, the straight line is the shortest. Therefore, the distance between the two devices connected by the connection structure 1 is shorter, and the length of the connection structure 1 is naturally shorter. Moreover, the connection assembly includes at least two connection structures 1 located in the same plane. This means that the inlets and outlets of at least three devices are located in the same plane (specifically, it means that the outlet of the first device, the inlet and outlet of the second device, and the inlet of the third device are located in the same plane). Obviously, the connection assembly includes at least two connection structures 1 located in the same plane. This at least shortens the lengths of the two connection structures 1 between the three devices, thereby reducing the overall occupied space of the connection structure 1 and the devices.
[0029] The first connection area 2 and the second connection area 3 are connected and communicated, which enables the medium to smoothly reach the second connection area 3 from the outlet of the previous device through the first connection area 2, and then enter the latter device through the second connection area 3 and the inlet of the latter device.
[0030] In the present utility model, the cross-section of the connection structure 1 is flat. Compared with other forms of connection structures 1, by setting the connection structure 1 to be flat, the thickness of the connection structure 1 is reduced, thereby further reducing the overall space occupied by multiple connection structures 1 and multiple devices.
[0031] When the cross-section of the connection structure 1 is flat, there are various setting forms. For example, the connection structure 1 can be a connection pipe with a square, oval or other shaped cross-section. As Figure 2 shown, the connection structure 1 includes a flow channel groove, and the flow channel groove is provided with a connected inlet and outlet. The inlet constitutes the first connection area 2, and the outlet constitutes the second connection area 3. The flow channel groove omits the top cover plate, further reducing the thickness of the connection structure 1 and further reducing the overall space occupied by multiple connection structures 1 and multiple devices.
[0032] Furthermore, in the present utility model, the first connection area 2 can be fitted with the outlet of the previous device, and / or the second connection area 3 can be fitted with the inlet of the subsequent device. This is equivalent to removing the gap between the first connection area 2 and the outlet of the previous device, and the gap between the second connection area 3 and the inlet of the subsequent device, making multiple connection structures 1 and multiple devices more compact and occupying less overall space. At the same time, this eliminates the problem of high manufacturing cost and large space occupation caused by the need to set up additional channels due to the gap between the first connection area 2 and the outlet of the previous device.
[0033] However, it should be noted that setting the cross-section of the connection structure 1 to be flat will also bring some negative problems. For example, because the cross-section of the connection structure 1 is flat and the thickness is small, the flexural stiffness of the connection structure 1 is low. Therefore, in the present utility model, a reinforcing member is provided on the connection structure 1 to increase the stiffness of the connection structure 1 and make the connection structure 1 have a strong flexural stiffness. The reinforcing member can be provided on the outside of the connection structure 1 and / or inside the connection structure 1. The reinforcing member can specifically be a reinforcing rib, a reinforcing rib, a reinforcing plate, or other structures that can enhance the strength of the connection structure 1.
[0034] And / or, the corners of the connection structure 1 have a smooth transition area. The smooth transition area can specifically be an arc transition, i.e., a fillet, provided at the corners of the connection structure 1; this avoids the problem of stress concentration in the connection structure 1.
[0035] It should also be noted that when the cross-section of the connection structure 1 is flat, due to the large width of the connection structure 1, the contact area between the medium and the pipe wall is also large, which will cause the boundary layer (the area where the fluid velocity gradually increases from zero) to thicken. The thicker the boundary layer, the greater the viscous friction force of the fluid, thereby increasing the resistance to the flow of the medium. Therefore, in the present application, a plurality of flow guiding vanes are provided in the connection structure 1. By setting the flow guiding vanes, the medium can flow in a set direction, suppressing the boundary layer separation at the edge of the medium and reducing the resistance caused by the boundary layer separation.
[0036] When the connection assembly includes a plurality of connection structures 1, the plurality of connection structures 1 can be annularly distributed, so as to realize the multi-directional utilization of space, making the plurality of connection structures 1 and the equipment more compact and occupying less space.
[0037] The medium in the present utility model can be a gas or a liquid. When the medium is a solid, when the medium can flow in the previous device, the connection structure and the subsequent device, this solid can also be selected as the medium.
[0038] The connection assembly in the present utility model is not limited to being used in the heat exchange module, and can also be used in other scenarios where the medium needs to be transferred from the previous device to the subsequent device. For example Figure 2 As shown, when the connection assembly is used in the heat exchange module, specifically four connection structures 1 can be provided, so as to connect the compressor 4, the first heat exchanger 5, the expansion valve 7, and the second heat exchanger 6 in sequence end to end, and at the same time make the outlet of the previous structure and the inlet of the subsequent structure in at least two connected structures among the compressor 4, the first heat exchanger 5, the expansion valve 7, and the second heat exchanger 6 be in the same plane, so that the heat exchange module formed by the compressor 4, the first heat exchanger 5, the expansion valve 7, and the second heat exchanger 6 is more compact and occupies less space. And when the inlets and outlets of the compressor 4, the first heat exchanger 5, the expansion valve 7, and the second heat exchanger 6 are all in the same plane, the heat exchange module and the plurality of connection structures 1 occupy less space. And as Figure 1 、 Figure 2 As shown, the connection structure 1 in the present utility model has various setting forms, and is not limited to Figure 1 、 Figure 2 the four forms of the connection structure 1 in, and those that meet the above-mentioned limiting conditions of the connection structure 1 can also be used as the connection structure 1 (the limiting conditions refer to that the connection structure 1 is used to connect two devices that need to be connected together, so that the medium in the previous device can flow to the subsequent device; at least two connection structures 1 are in the same plane).
[0039] The present utility model discloses a heat exchange module, and the heat exchange module includes the connection assembly described above. Moreover, the heat exchange module is not only used in the thermal management system of vehicles, but also can be used in other scenarios that require heat exchange, for example, in indoor or outdoor devices that require heat exchange, such as air conditioning systems.
[0040] Furthermore, the present utility model also discloses a thermal management system, which includes the heat exchange module described above. The thermal management system can be used in vehicles such as fuel engine vehicles, electric vehicles, or the like.
[0041] In addition, the present utility model also discloses a vehicle, which includes the thermal management system described above.
[0042] It should be noted that there are multiple technical solutions in the claims and the specification of the present utility model, but there is no situation of giving opposite technical inspiration.
[0043] Specific examples are used in the present utility model to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
