Description

Technical Field

[0001] This application belongs to the field of condenser technology, and particularly relates to a condenser. Background Technology

[0002] A heat exchanger is a device placed between two environments with a temperature difference and configured to absorb heat from one environment and release heat to the other. Within a heat exchanger, a condenser is a heat exchanger that cools the refrigerant by exchanging heat between the refrigerant and air or a coolant.

[0003] US Patent Publication No. 12235054B2 discloses an integrated connector and a heat exchanger including the integrated connector, wherein the connector body is formed by pressing a tube, and a cover is press-fitted into the connector body, such that the integrated connector is formed such that the interior of the connector body is sealed by the cover. Therefore, the number of components used in manufacturing the connector for connecting and securely linking the manifold and the gas-liquid separator can be reduced.

[0004] The aforementioned patent reduces brazing defects at the points where connections are needed by using connectors. However, in actual installation, there is still a problem of engagement defects during insertion, which needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a condenser that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a condenser, comprising:

[0007] First liquid tank;

[0008] The second liquid collection tank is located on one side of the first liquid collection tank and has multiple fins and connecting pipes between them.

[0009] A gas-liquid separator is located on the other side of the second liquid collection tank;

[0010] A connector assembly, disposed between the gas-liquid separator and the second liquid collection tank, includes a fixed connector and a transmission connector;

[0011] The second liquid collection tank and the gas-liquid separator are respectively provided with a first mounting hole and a second mounting hole that cooperate with the fixed connector, as well as a third mounting hole and a fourth mounting hole that cooperate with the transmission connector.

[0012] By incorporating a connector assembly that includes a fixed connector and a transmission connector, potential mating defects during installation can be effectively resolved. The fixed connector and transmission connector respectively mate with the mounting holes on the second liquid collection tank and the gas-liquid separator, ensuring the stability and reliability of the connection points and reducing mating defects caused by improper installation or inaccurate fitting. The installation of the gas-liquid separator allows the condenser to better perform its gas-liquid separation function, improving condensation efficiency. Furthermore, the introduction of the connector assembly does not interfere with the normal operation of the gas-liquid separator; on the contrary, the stable connection ensures the smooth progress of the gas-liquid separation process.

[0013] By optimizing the connection structure, the brazing quality of the condenser at the connection points is improved. The precise fit of the connector components reduces defects caused by improper brazing, thereby improving the overall manufacturing quality and durability of the condenser.

[0014] Furthermore, the fixed connector includes:

[0015] The first main body is cylindrical;

[0016] The first docking surface is located on one side of the main body and corresponds to the outer wall of the second collection tank;

[0017] The second docking surface is located on the other side of the main body and corresponds to the outer wall of the gas-liquid separator.

[0018] The first connecting part includes a first protrusion and a second protrusion, which are respectively disposed on the first mating surface and the second mating surface, and both the first protrusion and the second protrusion are cylindrical.

[0019] The first protrusion and the second protrusion respectively mate with the first mounting hole and the second mounting hole, and are connected by welding flux.

[0020] The first body of the fixed connector is cylindrical, which not only facilitates processing and installation but also provides stable structural support. The first and second mating surfaces correspond to the outer walls of the second liquid collection tank and the gas-liquid separator, respectively, ensuring a tight fit between the connector and these two components. The first and second protrusions are located on the first and second mating surfaces, respectively, and are both cylindrical, increasing the welding contact area. This allows the outer wall of the protrusion to make more thorough contact and fusion with the inner wall of the mounting hole during brazing, improving the weld strength and helping to reduce welding defects.

[0021] During the connection, the first and second protrusions press against each other and fit tightly against the inner walls of the first and second mounting holes, which helps to eliminate welding gaps and ensures a tight fit between the protrusions and the mounting holes during the welding process. The subsequent brazing process forms a brazing interlayer between the protrusions and the mounting holes, further enhancing the stability and reliability of the connection.

[0022] Furthermore, the first and second mating surfaces are arc-shaped, and the curvature of the first mating surface is the same as the curvature of the side of the second liquid collection tank, while the curvature of the second mating surface is the same as the curvature of the side of the gas-liquid separator.

[0023] Both the first and second mating surfaces are arc-shaped, matching the curvature of the sides of the second liquid collection tank and the gas-liquid separator, respectively. This allows the fixed connector to fit more perfectly onto these two components, reducing gaps caused by shape mismatches and enhancing the stability and adaptability of the connection. Furthermore, the arc-shaped mating surface design not only helps eliminate connection gaps but also creates a tighter seal at the connection point. When the first and second protrusions mate and press against the first and second mounting holes, respectively, the arc-shaped mating surface ensures a tight fit between the protrusions and the mounting holes, improving connection strength. It also simplifies installation steps, reduces installation difficulty and cost, and improves installation efficiency.

[0024] Furthermore, the first and second protrusions are provided with multiple grooves, which are fan-shaped.

[0025] By creating multiple fan-shaped grooves on the first and second protrusions, these grooves provide a reference for the initial positioning of the connector within the first and second mounting holes. During installation, operators can more easily align the protrusions with the mounting holes and confirm the accuracy of the initial positioning by checking the contact between the grooves and the edges of the mounting holes. This reduces installation errors caused by inaccurate positioning and improves installation efficiency. Furthermore, the grooves not only aid in initial positioning but also stabilize the connection during brazing. When the protrusions fit tightly with the mounting holes, the shape and distribution of the grooves help guide the flow of brazing material. The brazing material fills the grooves, forming a stronger weld joint, ensuring a uniform and thorough welding process, thereby improving weld quality.

[0026] Furthermore, the transmission connector includes:

[0027] The second main body is cylindrical;

[0028] The third docking surface is located on one side of the main body and corresponds to the outer wall of the second collection tank;

[0029] The fourth docking surface is located on the other side of the main body and corresponds to the outer wall of the gas-liquid separator;

[0030] The second connecting part includes a third protrusion and a fourth protrusion, which are respectively disposed on the third mating surface and the fourth mating surface, and both the third protrusion and the fourth protrusion are cylindrical;

[0031] The third and fourth protrusions mate with the third and fourth mounting holes respectively and are connected by welding flux.

[0032] Furthermore, the second main body is provided with a through groove that connects the third protrusion and the fourth protrusion, and the through groove is used for the flow of coolant.

[0033] By incorporating a through-groove within the second body of the transmission connector, connecting the third and fourth protrusions, smooth refrigerant flow within the condenser is ensured. The third and fourth protrusions of the transmission connector mate with the third and fourth mounting holes, respectively, and are soldered together using flux. This ensures a tight connection between the connector and the second liquid collection tank and the gas-liquid separator, reducing the risk of leakage due to loose connections. Simultaneously, the cylindrical design of the protrusions increases the contact area, improves the strength of the welded joint, and further enhances the stability of the connection.

[0034] Furthermore, a positioning groove is provided on the top of the second main body.

[0035] The positioning groove on the top of the second body of the transmission connector serves as a preliminary positioning feature. During installation, the operator can align the positioning groove with the center line of the corresponding mounting hole on the second liquid collection tank or gas-liquid separator, thereby ensuring the accurate position of the connector before brazing, reducing installation errors caused by inaccurate positioning, and improving installation efficiency and accuracy.

[0036] The beneficial effects of this application are:

[0037] 1. By setting up a fixed connector and a transmission connector, the problem of joint defects that may occur during installation can be effectively solved. The fixed connector and the transmission connector are respectively matched with the mounting holes on the second liquid collection tank and the gas-liquid separator to ensure the stability and reliability of the connection parts, thereby reducing joint defects caused by improper installation or inaccurate matching.

[0038] 2. By optimizing the connection structure, the brazing quality of the condenser at the parts that need to be connected has been improved. The precise fit of the connector components has reduced defects caused by improper brazing, thereby improving the overall manufacturing quality and durability of the condenser.

[0039] 3. The grooves not only help with initial positioning, but also play a role in stabilizing the connection during the brazing process. When the protrusions fit tightly with the mounting holes, the shape and distribution of the grooves help guide the flow of brazing material. The brazing material will fill the grooves to form a stronger weld joint, ensuring that the welding process is uniform and sufficient, thereby improving the welding quality.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] The condenser provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0047] Example 1:

[0048] like Figures 1 to 3 As shown, this application provides a condenser, including:

[0049] First liquid tank 100;

[0050] The second liquid collection tank 200 is located on one side of the first liquid collection tank 100 and has multiple fins and connecting pipes between it and the first liquid collection tank 100.

[0051] The gas-liquid separator 300 is located on the other side of the second liquid collection tank 200;

[0052] A connector assembly, disposed between the gas-liquid separator 300 and the second liquid collection tank 200, includes a fixed connector 400 and a transmission connector 500;

[0053] The second liquid collection tank 200 and the gas-liquid separator 300 are respectively provided with a first mounting hole 600 and a second mounting hole 610 that cooperate with the fixed connector 400, and a third mounting hole 620 and a fourth mounting hole 630 that cooperate with the transmission connector 500.

[0054] In some embodiments of this application, such as Figure 1 As shown, by setting up a connector assembly including a fixed connector 400 and a transmission connector 500, potential joint defects during installation can be effectively solved. The fixed connector 400 and the transmission connector 500 respectively cooperate with the mounting holes on the second liquid collection tank 200 and the gas-liquid separator 300 to ensure the stability and reliability of the connection, thereby reducing joint defects caused by improper installation or inaccurate fitting. The installation of the gas-liquid separator 300 enables the condenser to better achieve gas-liquid separation and improve condensation efficiency. At the same time, the introduction of the connector assembly does not interfere with the normal operation of the gas-liquid separator 300; on the contrary, the stable connection ensures the smooth operation of the gas-liquid separation process.

[0055] By optimizing the connection structure, the brazing quality of the condenser at the connection points is improved. The precise fit of the connector components reduces defects caused by improper brazing, thereby improving the overall manufacturing quality and durability of the condenser.

[0056] Example 2:

[0057] This application provides a condenser that, in addition to the above-mentioned technical features, also includes the following technical features.

[0058] like Figures 1 to 3 As shown, the fixed connector 400 includes:

[0059] The first main body 410 is cylindrical;

[0060] The first docking surface 420 is located on one side of the main body and corresponds to the outer wall of the second liquid collection tank 200;

[0061] The second docking surface 430 is located on the other side of the main body and corresponds to the outer wall of the gas-liquid separator 300.

[0062] The first connecting portion 440 includes a first protrusion 441 and a second protrusion 442, which are respectively disposed on the first mating surface 420 and the second mating surface 430, and both the first protrusion 441 and the second protrusion 442 are cylindrical.

[0063] The first protrusion 441 and the second protrusion 442 respectively mate with the first mounting hole 600 and the second mounting hole 610, and are connected by soldering flux.

[0064] In this embodiment, the first body 410 of the fixed connector 400 is cylindrical, which not only facilitates processing and installation but also provides stable structural support. The first mating surface 420 and the second mating surface 430 correspond to the outer walls of the second liquid collection tank 200 and the gas-liquid separator 300, respectively, ensuring a tight fit between the connector and these two components. The first protrusion 441 and the second protrusion 442 are located on the first mating surface 420 and the second mating surface 430, respectively, and are both cylindrical, increasing the welding contact area. This allows the outer wall of the protrusion to make more full contact and fuse with the inner wall of the mounting hole during brazing, which not only improves the weld strength but also helps to reduce welding defects.

[0065] During the connection, the first protrusion 441 and the second protrusion 442 press against each other and fit tightly against the inner walls of the first mounting hole 600 and the second mounting hole 610, thereby helping to eliminate welding gaps and ensuring a tight fit between the protrusions and the mounting holes during the welding process. The subsequent brazing process will form a brazing interlayer between the protrusions and the mounting holes, further enhancing the stability and reliability of the connection.

[0066] Furthermore, the first mating surface 420 and the second mating surface 430 are arc-shaped, and the curvature of the first mating surface 420 is the same as the curvature of the side of the second liquid collection tank 200, and the curvature of the second mating surface 430 is the same as the curvature of the side of the gas-liquid separator 300.

[0067] Both the first mating surface 420 and the second mating surface 430 are arc-shaped and match the side curvature of the second liquid collection tank 200 and the gas-liquid separator 300, respectively. This allows the fixed connector 400 to fit more perfectly onto these two components, reducing gaps caused by shape mismatch and thus enhancing the stability and adaptability of the connection. Simultaneously, the arc-shaped mating surface design not only helps eliminate connection gaps but also creates a tighter seal at the connection point. When the first protrusion 441 and the second protrusion 442 mate and press against the first mounting hole 600 and the second mounting hole 610, respectively, the arc-shaped mating surface ensures a tight fit between the protrusion and the mounting hole, improving connection strength. It also simplifies the installation process, reduces installation difficulty and cost, and improves installation efficiency.

[0068] Example 3:

[0069] This application provides a condenser that, in addition to the above-mentioned technical features, also includes the following technical features.

[0070] like Figures 1 to 3 As shown, the first protrusion 441 and the second protrusion 442 are provided with a plurality of grooves 450, which are fan-shaped.

[0071] In this embodiment, by forming multiple fan-shaped grooves 450 on the first protrusion 441 and the second protrusion 442, the fan-shaped grooves 450 provide a reference for the initial positioning of the fixed connector 400 in the first mounting hole 600 and the second mounting hole 610. During installation, the operator can more easily align the protrusion with the mounting hole and confirm the accuracy of the initial positioning by the contact between the groove 450 and the edge of the mounting hole, reducing installation errors caused by inaccurate positioning and improving installation efficiency. Simultaneously, the grooves 450 not only aid in initial positioning but also play a role in stabilizing the connection during brazing. When the protrusion and the mounting hole are tightly fitted, the shape and distribution of the grooves 450 help guide the flow of brazing material. The brazing material fills the grooves 450, forming a stronger weld joint, ensuring a uniform and sufficient welding process, thereby improving welding quality.

[0072] Example 4:

[0073] This application provides a condenser that, in addition to the above-mentioned technical features, also includes the following technical features.

[0074] like Figures 1 to 3 As shown, the transmission connector 500 includes:

[0075] The second main body, 510, is cylindrical;

[0076] The third docking surface 520 is located on one side of the main body and corresponds to the outer wall of the second liquid collection tank 200;

[0077] The fourth docking surface 530 is located on the other side of the main body and corresponds to the outer wall of the gas-liquid separator 300;

[0078] The second connecting part 540 includes a third protrusion 541 and a fourth protrusion 542, which are respectively disposed on the third mating surface 520 and the fourth mating surface 530, and both the third protrusion 541 and the fourth protrusion 542 are cylindrical.

[0079] The third protrusion 541 and the fourth protrusion 542 respectively mate with the third mounting hole 620 and the fourth mounting hole 630, and are connected by welding with brazing flux.

[0080] Furthermore, the second body 510 is provided with a through groove 511 that connects the third protrusion 541 and the fourth protrusion 542, and the through groove 511 is used for the flow of coolant.

[0081] In this embodiment, a through groove 511 connecting the third protrusion 541 and the fourth protrusion 542 is provided in the second body 510 of the transmission connector 500, ensuring smooth flow of coolant inside the condenser. The third protrusion 541 and the fourth protrusion 542 of the transmission connector 500 respectively mate with the third mounting hole 620 and the fourth mounting hole 630 and are welded together with solder, ensuring a tight connection between the connector and the second liquid collection tank 200 and the gas-liquid separator 300, reducing the risk of leakage due to loose connections. Simultaneously, the cylindrical design of the protrusions increases the contact area, improves the strength of the welded joint, and further enhances the stability of the connection.

[0082] Furthermore, a positioning groove 512 is provided on the top of the second main body 510.

[0083] The positioning groove 512 opened on the top of the second body 510 of the transmission connector 500 plays a preliminary positioning role. During the installation process, the operator can align the positioning groove 512 with the center line of the corresponding mounting hole on the second liquid collection tank 200 or the gas-liquid separator 300, thereby ensuring the accurate position of the connector before brazing, reducing installation errors caused by inaccurate positioning, and improving installation efficiency and accuracy.
