Description

Technical Field

[0001] This utility model belongs to the field of vehicle thermal management and relates to a novel plate condenser liquid storage tank structure. Background Technology

[0002] Traditional plate condensers typically employ an external liquid receiver design. This external structure requires specialized piping to connect the liquid receiver to the condenser and other related components to achieve refrigerant storage and circulation.

[0003] However, the above structure has some problems. First, the presence of an external liquid storage tank and numerous connecting pipes significantly increases the space occupied by the entire system, requiring more space to be reserved both internally and in the overall installation environment. Second, the use of numerous components and the complex assembly process directly leads to increased processing costs and requires more manpower. Furthermore, due to the external connection method and numerous pipe interfaces, refrigerant leakage is unavoidable to some extent during long-term operation due to factors such as temperature changes and vibration, posing certain safety hazards.

[0004] Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content

Example

[0035] See Figures 1-4 As shown, a novel plate condenser liquid storage tank structure is designed to solve many problems faced by traditional external liquid storage tank plate condensers. The structure mainly includes a base plate 1, which has a coolant inlet, providing an inlet channel for the coolant circulation of the entire system.

[0036] On the base plate 1, the subcooling component 2, storage component 3, and heat exchange component 4 are arranged sequentially from bottom to top. The three components adopt an integrated structural design: the upper end of the subcooling component 2, and the upper and lower ends of the storage component 3 and heat exchange component 4 are all designed with a bowl-shaped structure, allowing the three components to be stacked sequentially. This greatly optimizes space utilization, reduces the number of parts, and simplifies the assembly process. Specifically, the heat exchange component 4 is the refrigerant heat exchange area, the storage component 3 is the refrigerant storage area, and the subcooling component 2 is the refrigerant subcooling area.

[0037] In this embodiment, the bowl-shaped structure refers to a retaining edge surrounding the edges of the subcooling component 2, the storage component 3, and the heat exchange component 4. When the subcooling component 2, the storage component 3, and the heat exchange component 4 are stacked and assembled, the retaining edge acts as a limiting element, ensuring the stability of the positions of adjacent subcooling components 2 and storage components 3, and storage components 3 and heat exchange components 4.

[0038] The subcooling assembly 2 serves as the refrigerant subcooling area, and is constructed from the first stacked fin assembly, forming staggered first cooling chambers and first refrigeration chambers. These first cooling chambers are connected to the coolant inlet, allowing coolant to flow into them. Simultaneously, the first refrigeration port 22 is connected to the first refrigeration chamber. The storage assembly 3 serves as the refrigerant storage area, containing a liquid storage chamber 311. The second refrigeration port 321 and the third refrigeration port 331 at the upper and lower ends are respectively connected to the liquid storage chamber 311. The third refrigeration port 331 corresponds vertically to and is connected to the first refrigeration port 22, ensuring smooth refrigerant flow. Furthermore, the storage assembly 3 also contains an independent cooling channel 34, the lower end of which is connected to the first cooling port 21 for further coolant transfer.

[0039] The heat exchange assembly 4 serves as the refrigerant heat exchange area, forming an interlaced second cooling chamber and a second refrigeration chamber from the second stacked fin assembly. The second cooling port 41 and the third cooling port at its upper and lower ends are connected to the second cooling chamber, and the third cooling port is correspondingly connected to the upper end of the cooling channel 34 to achieve coolant circulation. The fifth refrigeration port 42 and the fourth refrigeration port are connected to the second refrigeration chamber, and the fourth refrigeration port is correspondingly connected to the second refrigeration port 321, ensuring effective heat exchange of the refrigerant.

[0040] The first and second plate assemblies described above form two staggered chambers, which is prior art in this field. See CN111750710A-plate condenser for reference. Therefore, they will not be described further in this embodiment.

[0041] It is worth mentioning that the flow channel 6 on the subcooling component 2 is connected to the first refrigeration chamber and passes through the storage component 3 and the heat exchange component 4 sequentially, making the refrigerant flow between the components smoother and more efficient. This new structure effectively avoids the problems of large space occupation, many parts, complex assembly, high cost and leakage risk caused by traditional external liquid storage tanks, and improves the overall performance and safety of plate condensers.

[0042] Of course, to improve the overall aesthetics and structural integrity, a cover plate 5 is installed at the top of the heat exchange component 4. Several key parts are precisely laid out on the cover plate 5: a first small hole 53 for the flow channel pipe 6 to pass through smoothly, ensuring that the flow channel pipe 6 can extend upward stably; a refrigerant inlet 51 that is precisely aligned with the fifth cooling port 42, providing a precise channel for the refrigerant to enter; and a coolant outlet 52 that is aligned with the second cooling port 41, allowing the coolant to be discharged in an orderly manner.

[0043] In this embodiment, the first lamination assembly, as the core component of the subcooling assembly 2, is ingeniously combined with alternating first and second open laminations. Between adjacent first and second open laminations, first cooling chambers and first refrigeration chambers are precisely spaced apart. This unique structural design allows the coolant and refrigerant to flow orderly within their respective chambers, achieving efficient heat exchange and subcooling.

[0044] Similarly, the second lamination assembly plays a crucial role in heat exchange assembly 4. It is constructed from alternating third and fourth open laminations. Second cooling chambers and second refrigeration chambers are spaced apart between adjacent third and fourth open laminations. This configuration allows the refrigerant to fully exchange heat within the second refrigeration chamber, while the coolant circulates within the second cooling chamber to remove heat, ensuring stable and efficient heat exchange performance of the heat exchange assembly.

[0045] Through this meticulously designed stacked assembly structure, the new plate condenser liquid storage tank structure achieves ideal results in refrigerant subcooling, storage, and heat exchange, further improving the overall efficiency and reliability of the condenser.

[0046] In the novel plate condenser liquid storage tank structure, the subcooling component 2 is equipped with two first cooling ports 21 to ensure efficient coolant inflow. The storage component 3 is provided with two cooling channels 34 to ensure stable coolant transmission. The two second cooling ports 41 of the heat exchange component 4 work together to make coolant circulation smoother, jointly improving the overall performance and heat exchange efficiency of the condenser.

[0047] In this embodiment, the storage component 3 consists of a plate structure 31 and an upper sealing plate 32 and a lower sealing plate 33 distributed at the upper and lower ends of the plate structure 31. These components are tightly connected through a welding process to finally form a complete liquid storage tank structure.

[0048] The plate structure 31 is the core part of the storage component 3, consisting of numerous plates with identical structures stacked vertically. Each plate is carefully designed with a first opening 311 and a second opening 312. The first openings 311 are interconnected and together enclose a liquid storage chamber for storing refrigerant, providing a stable storage space for the refrigerant. The second openings 312 form an independent cooling channel 34.

[0049] In use, the refrigerant first enters the second cooling chamber of the heat exchange assembly 4 through the refrigerant inlet 51 on the cover plate 5, where it exchanges heat with the coolant in the second cooling chamber. During this process, the state of the refrigerant changes significantly, gradually condensing from a high-temperature, high-pressure gaseous state to a high-temperature, high-pressure liquid state.

[0050] Next, the refrigerant, now in a liquid state, flows into the liquid storage chamber of storage component 3. After a brief stay in the liquid storage chamber, it flows into the first refrigeration chamber of subcooling component 2. During this process, due to continuous heat exchange, the refrigerant further cools down, becoming a medium-temperature, high-pressure liquid. When further refrigerant adjustment and control are required, the liquid refrigerant in the first refrigeration chamber is extracted through the flow channel pipe 6 on subcooling component 2 and flows into the corresponding refrigerant valve, thereby achieving the orderly operation of the entire refrigeration cycle system.

[0051] The outstanding advantage of this invention lies in its integrated structural design. This design concept completely changes many of the drawbacks of traditional external liquid storage tanks. The previously complex and cumbersome assembly process is simplified, greatly reducing labor and time costs. At the same time, the overall product size is significantly reduced, and the requirements for installation space are correspondingly lowered, making the equipment more flexible in various application scenarios. In addition, the storage components adopt a plate-welded method to form the liquid storage chamber, which not only effectively improves the consistency of the structure and ensures the tight fit between the components, but also greatly enhances the safety of the product. The entire design reduces the manufacturing cost of the product itself, giving it a significant cost advantage over traditional structures.

[0052] Meanwhile, the novel plate-type condenser liquid storage tank structure of this utility model effectively avoids the leakage risk that is prone to occur in traditional external liquid storage tanks due to the large number of connecting parts, providing a solid guarantee for the stable and efficient operation of refrigeration equipment.
