[0002] The battery system includes a battery pack and a water cooling unit. The water cooling unit has a heat exchanger assembly. The battery pack is connected to a water cooling pipeline. The water cooling pipeline is connected to the heat exchanger assembly. The heat exchanger assembly is connected to an air inlet pipe and an air outlet pipe. The heat exchange medium is introduced into the heat exchanger assembly through the air inlet pipe to exchange heat with the liquid introduced into the heat exchanger through the water cooling pipeline. However, in the prior art, the air inlet pipe of the plate heat exchanger of the water cooling unit of the heavy truck battery system is mostly connected by a hard pipe.

In more serious cases, the air inlet pipe head will be damaged and cannot be assembled again, resulting in functional failure.

[0033] See also Figure 1 and Figure 2 As shown, the embodiment of the present application provides a heat exchanger assembly, comprising: a bracket 1, at least two heat exchangers 2 and a plurality of air inlet pipes. Each of the heat exchangers 2 is fixed to the bracket 1, and each of the air inlet pipes is respectively connected to the air inlet of the corresponding heat exchanger 2, wherein at least part of the air inlet pipes is a deformable air inlet pipe 31, and at least part of the pipe section of the deformable air inlet pipe 31 is a hose 312.

[0034] The heat exchanger assembly of the present application is configured as a deformable intake pipe 31 by partially configuring the intake pipe, thereby reducing failure problems caused by pipeline vibration, facilitating assembly of the heat exchanger assembly, and reducing manufacturing dimensional accuracy requirements for the water cooling unit.

[0035] In some possible embodiments, the hose 312 is any one of a nylon tube, a rubber tube and a corrugated tube. Preferably, when the hose 312 is a nylon tube, it can be made of nylon with a grade of PA6 and cut according to the tube length by a cutting machine.

[0036] In some possible implementations, the air inlet pipe is a hard air inlet pipe 32, the hard air inlet pipe 32 is connected to the air inlet of the heat exchanger 2, one end of the deformable air inlet pipe 31 is connected to the hard air inlet pipe 32, and the other end of the deformable air inlet pipe 31 is connected to the air inlet of the corresponding heat exchanger 2. The hard air inlet pipe 32 can be formed by bending 304 stainless steel with a grade of sus through a pipe bender. The bracket 1 can be made of hard aluminum alloy with a grade of 700L by bending with a bending machine.

[0037] In some possible implementations, the rigid air inlet pipe 32 is provided with a connecting pipe 321, and the deformable air inlet pipe 31 is fixed to the connecting pipe 321 by a clamp. For example, the deformable air inlet pipe 31 can be sleeved on the connecting pipe 321, and the clamp is sleeved on the deformable air inlet pipe 31, so that the deformable air inlet pipe 31 is tightly fitted on the rigid air inlet pipe 32 and is not easy to be detached.

[0038] The deformable air inlet pipe 31 can be a hose 312 as a whole, and the whole deformable air inlet pipe 31 can be made of nylon with a grade of PA6, which is cut according to the length of the pipe by a cutting machine. Alternatively, the deformable air inlet pipe 31 includes a hose 312 and a hard pipe 311, and the hose 312 and the hard pipe 311 are connected, and one of the hose 312 and the hard pipe 311 is connected to the connecting pipe 321, and the other is connected to the air inlet. The hard pipe 311 and the hose 312 can also be fixed by a clamp. If the hard pipe 311 and the connecting pipe 321 are connected, the hard pipe 311 and the connecting pipe 321 can also be fixed by a clamp.

[0039] In some possible implementations, when the heat exchanger assembly includes more heat exchangers 2, a flow divider may be provided on the rigid air inlet pipe 32, and the flow divider has a plurality of connecting pipes 321, each of which is connected to the gas channel of the rigid air inlet pipe 32. A plurality of deformable air inlet pipes 31 are respectively connected to the corresponding connecting pipes 321. The flow divider is a one-inlet-multiple-outlet structure, and the upstream pipe section of the rigid air inlet pipe 32 can be used as a mother pipe to separate a plurality of branch pipes, namely, connecting pipes 321, which are conveniently connected to the air inlet of the corresponding heat exchanger 2 through the deformable air inlet pipes 31.

[0040] In some possible implementation schemes, a bent plate 11 is provided on the top of the bracket 1, and a connecting plate 12 is vertically connected to the bent plate 11, and the connecting plate 12 is used to be connected to the crossbeam, for example, the connecting plate 12 is used to be welded to the crossbeam. A reinforcing plate 13 is connected between the connecting plate 12 and the bent plate 11. The crossbeam can be a structure used to connect the heat exchanger assembly on the water-cooled unit. In the prior art, the bracket 1 of the plate heat exchanger 2 of the water-cooled unit of the heavy-duty truck battery system is mostly a sheet metal structure. This structural form is prone to vibration when the water-cooled unit is working because of its low rigidity at the part connected to the crossbeam, resulting in vibration of the intake pipe of the plate heat exchanger 2. A reinforcing plate 13 structure is provided on the bent plate 11 of the bracket 1 provided in the present application to increase the rigidity of the bracket 1 and reduce the vibration of the heat exchanger 2 caused by the battery system frame.

[0041] In some possible implementations, the heat exchanger assembly includes two reinforcing plates 13, the two reinforcing plates 13 are spaced apart and arranged in parallel, and the two reinforcing plates 13 are respectively connected to the connecting plate 12 and the bending plate 11. The two reinforcing plates 13 significantly enhance the structural strength and structural rigidity between the bending plate 11 and the connecting plate 12, reduce the vibration of the battery system frame to the heat exchanger 2, and improve the reliability and safety of the heat exchanger 2. The heat exchanger 2 provided in the embodiment of the present application can be a plate heat exchanger.

[0042] In some possible implementations, two adjacent ones of the reinforcing plate 13, the bent plate 11 and the connecting plate 12 are welded or bent as an integral piece. For example, the reinforcing plate 13, the bent plate 11 and the connecting plate 12 are formed by shearing and bending the same metal plate, and are fully welded and fixed at the joint gaps formed between them.

[0043] In some possible implementations, the bracket 1 is provided with a plurality of connecting plates 14, and the connecting plates 14 are provided with strip grooves 141, and fasteners can pass through the strip grooves 141 to be connected to the corresponding structure. The provision of the strip grooves 141 reduces the assembly precision requirements and reduces the assembly difficulty.

Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
