Description

Technical Field

[0001] This utility model belongs to the technical field of radiators for new energy vehicles, and more specifically, relates to a plate heat exchanger assembly and vehicle for new energy vehicles. Background Technology

[0002] Currently, most new energy vehicles use long-range battery packs as energy storage devices and electric motors as the core driving force. During vehicle operation, the battery pack and motor generate a large amount of heat due to energy conversion, and their temperature gradually rises. If they cannot be effectively cooled, it will directly affect the performance and reliability of the battery pack and motor, and shorten their service life.

[0003] The cooling system of new energy vehicles needs to be compatible with two core systems: one is the air conditioning system using R134a refrigerant, and the other is the water circulation system using coolant. The plate heat exchanger assembly is a key heat dissipation component for the three-electric system (battery pack, motor, and electronic control unit). However, due to the limited space in the front of the vehicle, existing radiator assemblies are complex in piping design and large in overall size, increasing assembly difficulty. Therefore, designing a simple, lightweight, and compact radiator assembly to reduce assembly difficulty is of significant practical importance for production.

[0004] A search revealed that patent CN222505088U discloses a plate heat exchanger and a vehicle having the same. This application includes a heat exchanger body with multiple interfaces on its surface; multiple adapter flanges selectively connectable to one or more of the interfaces; the heat exchanger body is connected to at least one of an air conditioning line and a cooling line via the adapter flanges; wherein the adapter flange connected to the air conditioning line is angled relative to the horizontal plane.

[0005] This application shortens the length of air conditioning piping and can eliminate the need for air conditioning piping on plate heat exchangers, improving the applicability and versatility of the heat exchangers. Adapter flanges can be used to directly connect to the air conditioning system, achieving the goal of shortening piping and saving layout space. However, the industry still needs more diverse designs to address the problem of increased assembly difficulty due to the complex piping design and large overall size of existing radiator components. Utility Model Content

[0006] The problem to be solved In view of at least some of the problems existing in the prior art, this utility model proposes a plate heat exchanger assembly for new energy vehicles. Its purpose is to provide a heat exchanger component with a simple structure, lightweight and compact design, so as to reduce assembly difficulty and save assembly space.

[0007] Technical solution To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model discloses a plate heat exchanger assembly for new energy vehicles, including a base and a heat exchanger body disposed on the base, wherein the heat exchanger body is connected to a water circulation pipeline and a refrigerant circulation pipeline. The refrigerant circulation pipeline includes an electronic expansion valve installed on the heat exchanger body, wherein the refrigerant inlet and outlet channels of the electronic expansion valve are respectively connected to the corresponding interfaces on the heat exchanger body; The refrigerant inlet channel of the electronic expansion valve is connected to a first pipe, and the first pipe is connected to a second pipe via a solenoid valve; the refrigerant outlet channel of the electronic expansion valve is connected to a third pipe. The solenoid valve is mounted on the base and located on one side of the heat exchanger body.

[0008] In some embodiments, the base has a first connecting block and a second connecting block on its side; wherein the first connecting block is used to connect with the vehicle body, and the solenoid valve is disposed on the second connecting block.

[0009] In some embodiments, one end of the third pipe is detachably connected to the electronic expansion valve via a first pressure plate, and the other end is connected to a second pressure plate.

[0010] In some embodiments, one end of the second pipe is connected to the solenoid valve by bolts, and the other end is inserted into a slot on the second pressure plate.

[0011] In some embodiments, one end of the first pipe is detachably connected to an electronic expansion valve via a first pressure plate, and the other end is detachably connected to a solenoid valve via bolts.

[0012] In some embodiments, the first connecting block is provided with an assembly groove, and a buffer pad is fitted inside the assembly groove.

[0013] In some embodiments, the water circulation pipeline includes an inlet pipe and an outlet pipe; wherein the inlet pipe is connected to the inlet interface of the heat exchanger body, and the outlet pipe is connected to the outlet interface of the heat exchanger body by brazing.

[0014] This utility model also provides a vehicle, including a heat exchanger assembly, which is the aforementioned plate heat exchanger assembly for a new energy vehicle.

[0015] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The plate heat exchanger assembly for new energy vehicles of this utility model integrates the electronic expansion valve and the solenoid valve directly on the heat exchanger body. On the one hand, some transition supports and connecting pipes can be eliminated, which not only reduces the number of parts and simplifies the assembly process, but also the integrated design can greatly reduce the overall volume of the heat exchanger assembly, reduce the structural weight, and effectively save installation space. On the other hand, the "zero distance" integration of the electronic expansion valve and the heat exchanger body can minimize the flow path of the refrigerant from the expansion valve to the heat exchanger, reduce the cold loss of the refrigerant during the transmission process, and thus help improve the heat exchange efficiency.

[0016] (2) In this utility model, a plate heat exchanger assembly for a new energy vehicle has a base that is bolted to the vehicle via a first connecting block; the electronic expansion valve and the solenoid valve are both bolted to the heat exchanger body; during installation, it is not necessary to connect the individual components one by one, and during disassembly, only the key bolts need to be removed to remove the entire assembly, thereby further simplifying the assembly process and significantly improving maintenance efficiency. At the same time, a buffer pad is installed between the first connecting block and the vehicle, which can provide good protection and vibration reduction. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1 As shown, a plate heat exchanger assembly for a new energy vehicle in this embodiment includes a base 100 and a heat exchanger body 200 disposed on the base 100; wherein, the heat exchanger body 200 is connected to a water circulation pipeline 300 and a refrigerant circulation pipeline 400, and the refrigerant and circulating water form convection and exchange heat inside the heat exchanger body 200 to achieve the cooling operation of the circulating water.

[0023] Specifically, refer to Figure 2 As shown, the water circulation pipeline 300 includes an inlet pipe 310 and an outlet pipe 320; wherein, the inlet pipe 310 is connected to the inlet interface of the heat exchanger body 200; and the outlet pipe 320 is connected to the outlet interface of the heat exchanger body 200.

[0024] Preferably, the inlet pipe 310, the outlet pipe 320, and the corresponding interface are connected by brazing.

[0025] The refrigerant circulation pipeline 400 includes an electronic expansion valve 410 disposed on the heat exchanger body 200, and the refrigerant inlet and outlet channels of the electronic expansion valve 410 are respectively connected to the refrigerant inlet and outlet ports on the heat exchanger body 200.

[0026] Meanwhile, the refrigerant inlet of the electronic expansion valve 410 is connected to a first pipe 420, and the first pipe 420 is connected to a second pipe 430 through a solenoid valve 440; the refrigerant outlet of the electronic expansion valve 410 is connected to a third pipe 450.

[0027] Furthermore, the solenoid valve 440 is also mounted on the base 100 and located on one side of the heat exchanger body 200.

[0028] This embodiment of a plate heat exchanger assembly for new energy vehicles integrates an electronic expansion valve 410 and a solenoid valve 440 directly onto the heat exchanger body 200. On the one hand, this eliminates the need for some transition supports and connecting pipes, reducing the number of parts and simplifying the assembly process. Simultaneously, the integrated design significantly reduces the overall volume of the heat exchanger assembly, lightens the structural weight, and effectively saves installation space. On the other hand, the "zero-distance" integration of the electronic expansion valve 410 with the heat exchanger body 200 minimizes the refrigerant's flow path from the expansion valve into the heat exchanger body 200, reducing refrigerant cooling loss during transmission and thus improving heat exchange efficiency.

[0029] In some embodiments, the base 100 has a first connecting block 110 and a second connecting block 120 on its side; wherein the first connecting block 110 is used to connect with the vehicle body, and the solenoid valve 440 is disposed on the second connecting block 120.

[0030] Furthermore, the solenoid valve 440 is connected to the second connecting block 120, the first connecting block 110 is connected to the vehicle body, and the electronic expansion valve 410 is connected to the base 100 by bolts 480.

[0031] Meanwhile, one end of the third pipe 450 is detachably connected to the electronic expansion valve 410 via the first pressure plate 460, and the other end is connected to the second pressure plate 470. One end of the second pipe 430 is connected to the solenoid valve 440 via bolts 480, and the other end is inserted into a slot on the second pressure plate 470. One end of the first pipe 420 is detachably connected to the electronic expansion valve 410 via the first pressure plate 460, and the other end is detachably connected to the solenoid valve 440 via bolts 480.

[0032] In this embodiment, a plate heat exchanger assembly for a new energy vehicle is assembled by first pre-installing the electronic expansion valve 410, solenoid valve 440, and related pipes onto the heat exchanger body 200, and then assembling it onto the vehicle body via the first connecting block 110, which further simplifies the assembly process. During disassembly, the entire assembly can be removed from the vehicle first, and then individual components can be replaced by removing the connecting bolts between the electronic expansion valve 410, solenoid valve 440, and heat exchanger body 200.

[0033] In other words, in this embodiment, the components are detachably connected by bolts 480. During installation, it is not necessary to connect the individual components one by one. During disassembly, only the key bolts need to be removed to remove the whole assembly, which further simplifies the assembly process and greatly improves maintenance efficiency.

[0034] In some alternative embodiments, a buffer pad 130 is fitted between the first connecting block 110 and the vehicle to provide good protection and vibration reduction. Specifically, the buffer pad 130 is a columnar structure, and the first connecting block 110 is provided with a mounting groove for the buffer pad 130 to be inserted.
