Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a parallel flow evaporator, an air conditioning system, and a vehicle. Background Technology

[0002] With increasingly stringent global requirements for energy conservation, emission reduction, and environmental protection, the automotive industry faces immense pressure to reduce energy consumption. Traditional gasoline-powered vehicles need to lower fuel consumption to reduce carbon emissions. In the overall energy consumption of a vehicle, the in-vehicle environmental control system accounts for a significant portion, second only to the powertrain system, especially under low-temperature and hot conditions, where its energy consumption percentage increases significantly.

[0003] Currently, the heat exchangers used in automotive air conditioning systems are primarily parallel-flow heat exchangers made of aluminum. This type of heat exchanger typically delivers refrigerant to a manifold via a single tube, and then distributes the refrigerant to various branches from the manifold. However, this liquid-liquid separation is poor, resulting in low heat exchange efficiency and a very low overall refrigeration system efficiency. In particular, the evaporator contains a two-phase refrigerant system, where phase separation occurs within the manifold. This leads to variations in refrigerant flow rate and gas-liquid ratio in each branch, significantly reducing the evaporator's cooling capacity and increasing system energy consumption.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] The first aspect of this utility model provides a parallel flow evaporator, such as... Figures 1 to 6 As shown, it includes a core assembly 1, a first manifold 2, a second manifold 3, a liquid distribution pipe group 4, and an outlet pipe 5; The first manifold 2 and the second manifold 3 are respectively connected to the two ends of the core assembly 1 in the axial direction. The first manifold 2 includes an inlet chamber 21 and an outlet chamber 22, both of which are connected to the core assembly 1. The inlet chamber 21 includes a plurality of first sub-chambers 211 distributed along the axial direction of the first manifold 2. The second manifold 3 includes a transfer chamber 31 connected to the core assembly 1. The liquid distribution tube group 4 includes multiple liquid distribution tubes 41 that are connected to each of the first sub-chambers 211, and the air outlet tube 5 is connected to the liquid outlet chamber 22.

[0028] When the parallel flow evaporator provided in the first aspect of this utility model is in use, the refrigerant enters each of the first sub-chambers 211 from each of the liquid distribution pipes 41 in the liquid distribution pipe group 4, then enters the core assembly 1 through each of the first sub-chambers 211, then flows back to the core assembly 1 through the transfer and discharge chamber 31 in the second collector pipe 3, and finally is discharged from the liquid outlet chamber 22. The above-mentioned parallel flow evaporator can distribute the refrigerant to multiple first sub-chambers 211 of the liquid inlet chamber 21 through multiple liquid distribution pipes 41, which can improve the uniformity of the gas-liquid refrigerant distribution ratio in each branch of the evaporator, improve the heat exchange efficiency of the evaporator and the energy efficiency of the refrigeration system.

[0029] In alternative implementations, such as Figure 2 As shown, the liquid distribution tube assembly 4 also includes a liquid distribution head 42, and the end of each liquid distribution tube 41 away from the core assembly 1 is connected to the liquid distribution head 42.

[0030] The aforementioned liquid distributor 42 is a collection component with an internal flow cavity, used to receive refrigerant from the external refrigeration system pipeline and to evenly distribute the refrigerant into the multiple liquid distributors 41 connected to it.

[0031] Specifically, the dispensing head 42 is provided with a dispensing chamber along its axial direction, which is connected to the inlet end of each dispensing tube 41.

[0032] In alternative implementations, such as Figure 2 As shown, the parallel flow evaporator also includes a connector 6, which serves as the connection interface between the external piping system and the internal flow channel of the evaporator, used to achieve centralized introduction and export of refrigerant. Specifically, both the liquid distributor 42 and the outlet pipe 5 are connected to the connector 6, allowing the connector 6 to simultaneously perform the dual functions of refrigerant input and output, while also helping to define the position of the liquid distributor 42 relative to the outlet pipe 5.

[0033] Furthermore, the connector 6 is provided with at least two functional ports: one port is connected to the liquid distributor 42 for introducing liquid or gas-liquid mixture refrigerant from the external refrigeration system into the liquid distributor 42 and evenly distributing it to each liquid distributor 41 in the liquid distributor assembly 4 via the liquid distributor 42; the other port is connected to the gas outlet pipe 5 for drawing out the gaseous or residual gas-liquid mixture refrigerant after heat exchange and evaporation of the core assembly 1 from the liquid outlet chamber 22 and collecting it through the gas outlet pipe 5 to the connector 6 before returning it to the compressor or the next cycle component.

[0034] In alternative implementations, such as Figure 4 As shown, the first manifold 2 includes a first pipe body 23, a first longitudinal partition 24, and a plurality of first transverse partitions 25.

[0035] The first tube 23 is a hollow structure extending along its own axis. The axis of the first tube 23 is perpendicular to the axis of the core assembly 1. The first longitudinal partition 24 extends along the axis of the first tube 23 and is fixedly installed inside the first tube 23, dividing the inner cavity of the first tube 23 into two independent functional chambers: an inlet chamber 21 located on one side and an outlet chamber 22 located on the other side.

[0036] It is understandable that the axial direction of the first tube 23 mentioned above is... Figure 4 The up and down directions in the middle.

[0037] Each first transverse partition 25 is arranged at intervals along the axial direction of the first manifold 2 and is located inside the liquid inlet chamber 21. Each first transverse partition 25 is perpendicular to the first longitudinal partition 24 and is fixedly connected to the inner wall of the first pipe body 23 and the first longitudinal partition 24, thereby dividing the liquid inlet chamber 21 into multiple first sub-chambers 211 along the axial direction.

[0038] The number of first diaphragms 25 can be determined according to actual needs, such as two, three, four, five or six, and their number is equal to the number of liquid distribution tubes 41 in the liquid distribution tube group 4, so as to achieve one-to-one correspondence and conduction.

[0039] like Figure 4 As shown, four first diaphragms 25 are provided, which divide the liquid inlet chamber 21 into five first sub-chambers 211 along the axial direction, thereby improving the uniformity of refrigerant distribution before entering the core assembly 1.

[0040] In alternative implementations, such as Figure 6 As shown, the second manifold 3 includes a second pipe body 32 and a second longitudinal partition 33; the second longitudinal partition 33 is installed inside the second pipe body 32 and divides the transfer chamber 31 into a receiving chamber 311 and a discharge chamber 312. The second longitudinal partition 33 is provided with a flow hole 331 that connects the receiving chamber 311 and the discharge chamber 312.

[0041] Specifically, the second tube 32 is a hollow structure extending along its own axis. The axis of the second tube 32 is perpendicular to the axis of the core assembly 1 and parallel to the axis of the first tube 23. Its internal space is divided into two functionally independent chambers by the second longitudinal partition 33 disposed therein: a receiving chamber 311 located on one side and a discharge chamber 312 located on the other side. Together, they constitute the overall flow path structure of the transfer and discharge chamber 31.

[0042] The second longitudinal partition 33 extends axially along the second tube body 32 and is fixedly installed on the inner wall of the second tube body 32. For example, a stable connection can be achieved by welding, riveting or integral molding process to ensure structural strength and sealing performance.

[0043] After completing one heat exchange process, the refrigerant first enters the receiving chamber 311. In order to achieve the orderly transfer of refrigerant from the receiving chamber 311 to the discharge chamber 312, at least one flow hole 331 is provided on the second longitudinal partition 33. The flow hole 331 penetrates the second longitudinal partition 33, so that the receiving chamber 311 and the discharge chamber 312 are in fluid communication.

[0044] The above-described embodiment, by setting a receiving cavity 311 and a discharge cavity 312 separated by a second longitudinal partition 33 in the second manifold 3, and cooperating with the flow passage 331 set thereon, achieves effective control of the refrigerant flow direction and flow rate during the transfer and discharge process, thereby improving the uniformity and controllability of the flow field inside the evaporator.

[0045] In alternative implementations, such as Figure 6 As shown, the second manifold 3 also includes a plurality of second transverse partitions 34, each of which is spaced apart along the axial direction of the second manifold 3 and installed within the receiving cavity 311, dividing the receiving cavity 311 into a plurality of independent second sub-cavities 3111. Each second sub-cavity 3111 communicates with the discharge cavity 312 through at least one flow hole 331 provided on the second longitudinal partition 33, thereby forming a multi-path flow channel from the receiving cavity 311 to the discharge cavity 312.

[0046] The above-described embodiment, through the synergistic effect of multiple second sub-chambers 3111 and corresponding flow holes 331, can enhance the adaptability to refrigerant flow distribution under different operating conditions. For example, under variable load operating conditions, this structure can balance the pressure differences between branches through a natural flow redistribution mechanism, reducing uneven distribution problems caused by gravity, inertia, or phase separation.

[0047] The flow passage 331 can take various shapes, such as circular or square.

[0048] In an optional implementation, the number of second sub-chambers 3111 is the same as the number of first sub-chambers 211.

[0049] The aforementioned structural design improves the uniformity of refrigerant distribution among the various branches within the parallel flow evaporator. Especially in applications with multiple parallel heat exchange channels, it effectively balances the pressure drop and phase change process of each heat exchange branch, thereby improving overall heat exchange efficiency. Simultaneously, this configuration facilitates system matching design and manufacturing assembly, simplifies piping layout and mold development complexity, and enhances product manufacturability and reliability.

[0050] In an optional embodiment, each of the second sub-chambers 3111 and each of the first sub-chambers 211 are arranged opposite each other along the axial direction of the core assembly 1.

[0051] The above-described implementation method optimizes the refrigerant flow organization and enhances the stability and energy efficiency of the evaporator under variable operating conditions by making the number of the second sub-chamber 3111 the same as the number of the first sub-chamber 211 and achieving a one-to-one spatial correspondence.

[0052] In alternative implementations, such as Figure 1 and Figure 7 As shown, the core assembly 1 includes a first row of cores 11 and a second row of cores 12 arranged opposite to each other. The first row of cores 11 is connected between the liquid inlet chamber 21 and the transfer chamber 31, forming a first-stage heat exchange path for refrigerant to flow from the liquid inlet chamber to the transfer chamber 31. The second row of cores 12 is connected between the transfer chamber 31 and the liquid outlet chamber 22, forming a second-stage heat exchange path for refrigerant to flow back from the transfer chamber 31 to the liquid outlet chamber.

[0053] Specifically, the first row of cores 11 and the second row of cores 12 are located in the front and rear rows of the parallel flow evaporator, respectively. They have the same or similar structure, both including multiple flat tubes and fins. The flat tubes and fins can be alternately arranged from top to bottom along the direction parallel to the axial direction of the first manifold 2. The flat tubes form a channel for refrigerant flow, and the fins are used to enhance the heat exchange efficiency with the outside air.

[0054] The refrigerant flow path is as follows: The refrigerant from the liquid distribution pipe group 4 first enters each of the first sub-chambers 211 in the liquid inlet chamber 21, and then flows into the first row of core bodies 11, where it undergoes the first evaporation and heat absorption in its channel; After the initial evaporation, the gas-liquid two-phase refrigerant enters the transfer chamber 31 of the second manifold 3, where the receiving chamber 311 temporarily stores the return refrigerant and guides it into the discharge chamber 312 through the flow passage 331, and then distributes it to the second row of core bodies 12; The refrigerant undergoes the second evaporation and heat exchange in the second row of core bodies 12, and after further sufficient vaporization, it flows into the liquid outlet chamber 22, and finally exits the evaporator through the gas outlet pipe 5.

[0055] The aforementioned dual-row core structure achieves two-stage refrigerant splitting and series heat exchange, effectively extending the refrigerant's flow path length within the evaporator and improving the heat exchange area utilization rate. Simultaneously, combined with the liquid distribution design of the multi-chamber in the first manifold 2 and the transfer chamber 31 structure in the second manifold 3, the refrigerant distribution between the two rows of cores becomes more uniform, avoiding local overheating or liquid accumulation, and significantly improving the overall heat exchange uniformity of the evaporator and the system energy efficiency ratio.

[0056] The second aspect of this utility model provides an air conditioning system, which includes the above-mentioned parallel flow evaporator.

[0057] The air conditioning system provided by the second aspect of this utility model, by integrating the aforementioned high-performance parallel flow evaporator, not only improves the system's energy efficiency ratio but also enhances its operational reliability and environmental adaptability, making it particularly suitable for modern intelligent air conditioning scenarios that pursue high efficiency, energy saving, and precise temperature control.

[0058] A third aspect of this utility model provides a vehicle that includes the aforementioned parallel flow evaporator or air conditioning system.

[0059] The vehicle provided by the third aspect of this utility model, because it is equipped with a parallel flow evaporator or corresponding air conditioning system with excellent refrigerant distribution performance and high heat exchange capacity, not only improves the energy efficiency and operational stability of the whole vehicle air conditioning system, but also improves the thermal comfort experience of the passenger compartment, and has good industrialization prospects and market application value.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
