Description

Technical Field

[0001] This invention belongs to the technical field of heat exchange equipment, specifically a water-cooled condenser with a liquid storage tank function. Background Technology

[0002] The automotive industry is one of the pillar industries in my country's industrial sector. With the rise of the electric vehicle industry and the continuous deepening of research on new refrigerants, the application of secondary circuits in automotive air conditioning systems is becoming more and more widespread. The increase in the number of components in the secondary circuit poses new challenges to the size of the air conditioning system and continuously increases the requirements for the integration of components.

[0003] Currently, whether it is a traditional split-type air conditioning system or a new integrated air conditioning system module, the water-cooled condenser and the liquid storage tank exist as two separate components in the system. This undoubtedly increases the space occupied by the system. The pipes connecting the water-cooled condenser and the liquid storage tank will also exchange heat with the outside, resulting in a decrease in system efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a water-cooled condenser with a liquid storage tank function.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a water-cooled condenser with a liquid storage tank function, comprising a top assembly, a plate assembly, and a bottom assembly, wherein the two ends of the plate assembly are respectively connected to the top assembly and the bottom assembly, the top assembly comprising a top plate; the bottom assembly comprising a bottom plate, the plate assembly comprising a standard plate assembly, the standard plate assembly being formed by stacking a first standard plate and a second standard plate from top to bottom, wherein a refrigerant flow layer and a coolant flow layer alternately exist in the gap between the first standard plate and the second standard plate, the plate assembly further comprising a liquid storage chamber inlet plate and a liquid storage chamber outlet plate. The plates, including the first ordinary plate, the second ordinary plate, the liquid storage chamber inlet plate, and the liquid storage chamber outlet plate, are all perforated with refrigerant inlet, refrigerant outlet, coolant inlet, and coolant outlet. These plates, when stacked, form refrigerant inlet channels, refrigerant outlet channels, coolant inlet channels, and coolant outlet channels, respectively. A coolant inlet pipe, a coolant outlet pipe, a refrigerant inlet pipe, and a refrigerant outlet pipe are fixedly installed on the top pressure plate. These coolant inlet pipes, coolant outlet pipes, and refrigerant inlet pipes are respectively connected to the coolant inlet channels, coolant outlet channels, and refrigerant inlet channels. The first ordinary plate... The second ordinary plate, the liquid storage chamber inlet plate, and the liquid storage chamber outlet plate have through grooves at the end near the refrigerant outlet. These through grooves are circumferentially fitted with flanged structures. These flanged structures, formed by stacking the bottom plate, top plate, first ordinary plate, second ordinary plate, liquid storage chamber inlet plate, and liquid storage chamber outlet plate, create a liquid storage chamber. The liquid storage chamber inlet plate and liquid storage chamber outlet plate are installed at one end of the ordinary plate assembly, and the top plate is in contact with the other end of the ordinary plate assembly. Flow structures are provided at the flanged structures on the liquid storage chamber inlet plate and liquid storage chamber outlet plate. The liquid storage chamber inlet plate is located above the liquid storage chamber inlet... The refrigerant flow layer where the inlet is located and the refrigerant flow layer where the liquid storage chamber outlet is located below the liquid storage chamber outlet plate are respectively connected to the liquid storage chamber through a flow structure. The liquid storage chamber inlet plate and the liquid storage chamber outlet plate are in a coolant flow layer. The liquid storage chamber outlet plate is in contact with the bottom plate. An outlet guide pipe is installed in the refrigerant outlet channel. The refrigerant outlet pipe is connected to the outlet guide pipe. The refrigerant outlet channel of the liquid storage chamber inlet plate and the liquid storage chamber outlet plate are sealed. The outlet guide pipe is located in the refrigerant outlet channel. The outlet guide pipe is connected to the liquid storage chamber between the liquid storage chamber outlet plate and the bottom plate through a flow structure.

[0006] As a further improvement: a bottom pressure plate is fixedly installed on the bottom plate.

[0007] As a further improvement: a top pressure plate is installed on the side of the top plate away from the plate assembly.

[0008] As a further improvement, the flange structure is provided with a flow guiding structure.

[0009] As a further improvement: the flow guiding structure includes a lower groove and an upper convex groove. The first ordinary plate has a lower groove at one end near the flange structure, and the second ordinary plate has a corresponding upper convex groove. The height of the lower groove and the upper convex groove is the same as the corrugation height on the plate, and the lower groove and the upper convex groove are sealed together.

[0010] As a further improvement: the flow structure includes a flow port and a confluence port. The flow port is provided on the flanged structure above the outlet plate of the liquid storage chamber, and the confluence port is provided on the flanged structure below the outlet plate of the liquid storage chamber.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: By organically combining the water-cooled condenser and the liquid receiver, and by designing the shape and structure of the plates inside the water-cooled condenser, a liquid receiver cavity capable of accommodating the refrigerant is naturally formed when the plates are stacked together, thus acting as a liquid receiver. This invention not only eliminates the connecting pipes between the water-cooled condenser and the liquid receiver, reducing heat loss and improving system integration, thus reducing the overall volume of the air conditioning system, but also releases heat to the coolant inside the water-cooled condenser while storing the liquid, further increasing the subcooling of the refrigerant at the outlet of the water-cooled condenser and improving system performance.

Detailed Implementation

[0023] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0025] Please see Figures 1 to 10In one embodiment, a water-cooled condenser with a liquid storage tank function includes a top assembly 1, a plate assembly 2, and a bottom assembly 3. The two ends of the plate assembly 2 are respectively connected to the top assembly 1 and the bottom assembly 3. The top assembly 1 includes a top plate 15; the bottom assembly 3 includes a bottom plate 31; the plate assembly 2 includes a standard plate assembly 21, which is formed by stacking a first standard plate 211 and a second standard plate 212 from top to bottom. A refrigerant flow layer 8 and a coolant flow layer 7 alternately exist in the gap between the first standard plate 211 and the second standard plate 212. The plate assembly 2 also includes a liquid storage chamber inlet plate 22 and a liquid storage chamber outlet plate 23. The liquid storage chamber outlet plate 22 and the liquid storage chamber outlet plate 23 are located at the bottom of the water-cooled condenser. The first ordinary plate 211, the second ordinary plate 212, the liquid storage chamber inlet plate 22, and the liquid storage chamber outlet plate 23 are all perforated with refrigerant inlet 81, refrigerant outlet 82, coolant inlet 71, and coolant outlet 72, respectively. The overlapping of the plates forms refrigerant inlet channels, refrigerant outlet channels, coolant inlet channels, and coolant outlet channels. The top pressure plate 15 is fixedly installed with coolant inlet pipe 11, coolant outlet pipe 12, refrigerant inlet pipe 13, and refrigerant outlet pipe 14. The coolant inlet pipe 11, coolant outlet pipe 12, and refrigerant inlet pipe 13 are respectively connected to the coolant inlet channels, coolant outlet channels, and refrigerant outlet channels. The channels are interconnected. The first ordinary plate 211, the second ordinary plate 212, the liquid storage chamber inlet plate 22, and the liquid storage chamber outlet plate 23 have through grooves at one end near the refrigerant outlet 82. Each through groove has an inwardly inclined flange structure 24. The flange structure 24 forms a liquid storage chamber 4 internally after the bottom plate 31, top plate 15, first ordinary plate 211, second ordinary plate 212, liquid storage chamber inlet plate 22, and liquid storage chamber outlet plate 23 are stacked. The liquid storage chamber inlet plate 22 and liquid storage chamber outlet plate 23 are installed at one end of the ordinary plate assembly 21, and the top plate 15 is in contact with the other end of the ordinary plate assembly 21. Coolant is present between the liquid storage chamber inlet plate 22 and the liquid storage chamber outlet plate 23. The refrigerant flow layer 7 is located above the inlet plate 22 of the liquid storage chamber, forming the refrigerant flow layer 5 where the liquid storage chamber inlet is located. The refrigerant flow layer 6 is located below the outlet plate 23 of the liquid storage chamber, forming the refrigerant flow layer 6 where the liquid storage chamber outlet is located. Flow structures 27 are provided at the flanged structures 24 on the inlet plate 22 and outlet plate 23 of the liquid storage chamber. The refrigerant flow layer 5 above the inlet plate 22 and the refrigerant flow layer 6 below the outlet plate 23 of the liquid storage chamber are respectively connected to the liquid storage chamber 4 through the flow structures 27. The outlet plate 23 of the liquid storage chamber is in contact with the bottom plate 31. An outlet guide pipe 26 is installed in the refrigerant outlet channel, and the refrigerant outlet pipe 14 is connected to the outlet guide pipe 26. The refrigerant outlet channel of the inlet plate 22 of the liquid storage chamber is sealed.The outlet guide pipe 26 is located within the refrigerant outlet channel. The diameter of the outlet guide pipe 26 is smaller than that of the refrigerant outlet channel on the ordinary plate assembly 21. The outer wall of the outlet guide pipe 26 forms a seal with the top plate 15 and with the liquid storage chamber outlet plate 23. By placing the outlet guide pipe 26 within the refrigerant outlet channel, the refrigerant outlet channel is divided into two parts: the area between the outlet guide pipe 26 and the refrigerant outlet channel, and the area inside the outlet guide pipe 26. The area between the outlet guide pipe 26 and the refrigerant outlet channel connects to all refrigerant flow layers 8 in the ordinary assembly. The area inside the outlet guide pipe 26 connects the refrigerant outlet pipe 14 with the refrigerant flow layer 6 where the liquid storage chamber outlet is located. The refrigerant flow layer 6 where the liquid storage chamber outlet is located is between the bottom plate 31 and the liquid storage chamber outlet plate 23.

[0026] In this embodiment, after the refrigerant enters the water-cooled condenser through the refrigerant inlet pipe 13, it flows through all the refrigerant flow layers 8. After completing the heat exchange with the coolant, according to the flow channel planning of the inlet plate 22 and the outlet plate 23 of the liquid storage chamber, it can only enter the liquid storage chamber 4, which is formed by the internal flange structure 24 on the plate assembly 2, the top plate 15, and the bottom plate 31, through the refrigerant flow layer 5 where the liquid storage chamber inlet is located. At the same time, it continues to release heat to the coolant flow layer 7 inside the water-cooled condenser to further increase the subcooling. Then, it enters the outlet guide pipe 26 through the refrigerant flow layer 6 where the liquid storage chamber outlet is located, and flows out of the water-cooled condenser from the refrigerant outlet pipe 14.

[0027] The coolant flows into the water-cooled condenser through the coolant inlet pipe 11 on the top component 1, flows through the coolant flow layer 7 in the gap between each plate, and then flows out of the water-cooled condenser through the coolant outlet pipe 12.

[0028] Please see Figure 2 In one embodiment, a bottom pressure plate 32 is fixedly installed on the bottom plate 31.

[0029] In this embodiment, the bottom pressure plate 32 is located below the bottom plate 31, providing a bottom support and mounting position for the water-cooled condenser.

[0030] Please see Figure 2 In one embodiment, a top pressure plate 16 is mounted on the side of the top plate 15 away from the plate assembly 2.

[0031] In this embodiment, the top plate 15 is the first plate at the top of the water-cooled condenser. The top plate 15 has a raised structure at one end of the refrigerant outlet 82. The top pressure plate 16 is located above the top plate 15 and is thicker than the top plate 15. It is used to support the four water-cooled condenser inlet and outlet pipes.

[0032] The top pressure plate 16 and the bottom pressure plate 32 can apply pressure to make several plates come into close contact, and combined with the brazing process, this ensures that there will be no leakage inside.

[0033] Please see Figure 3 , Figure 5 In one embodiment, the flange structure 24 is provided with a flow guiding structure 25, which is formed by stamping.

[0034] In this embodiment, the design of the flow guiding structure 25 allows the coolant to flow around the internal flange structure 24 within the plate, further cooling the refrigerant in the liquid storage chamber 4, thereby increasing the subcooling and improving the efficiency of the air conditioning system.

[0035] Due to the existence of such Figure 3 The flow guiding structure 25 shown has the following coolant flow direction within each coolant flow layer 7: Figure 6 As shown by the arrow on the coolant flow layer 7, a large portion flows directly to the main body of the water-cooled condenser, while the other portion flows around the internal flange structure 24, circling the liquid storage cavity 4 in the plate plane before flowing to the main body of the water-cooled condenser. During this process, the refrigerant in the liquid storage cavity 4 is cooled.

[0036] Please see Figure 3 , Figure 5 In one embodiment, the flow guiding structure 25 includes a lower groove and an upper protrusion. The first ordinary plate 211 has a lower groove at one end near the flange structure 24, and the second ordinary plate 212 has a corresponding upper protrusion. The height of the lower groove and the upper protrusion is the same as the height of the corrugations on the plate. The lower groove and the upper protrusion are sealed together. The flow guiding structure 25 only guides the flow of the coolant flow layer 7 and has no guiding effect on the flow of the refrigerant flow layer 8.

[0037] Please see Figure 3 , Figure 5 In one embodiment, the flow structure 27 includes a flow port and a confluence port. The flow port is provided on the flange structure 24 above the liquid storage chamber inlet plate 22, and the confluence port is provided on the flange structure 24 below the liquid storage chamber outlet plate 23.

[0038] The refrigerant enters the liquid storage chamber 4 from the refrigerant flow layer 5 (located above the inlet plate 22) through the flow port. The refrigerant then flows from the liquid storage chamber 4 to the refrigerant flow layer 6 (located at the outlet), and then exits through the outlet guide pipe 26. The refrigerant flow layer 6 at the outlet is located before the outlet plate 23 and the bottom plate 31 of the liquid storage chamber.

[0039] Please see Figures 7 to 10To further illustrate the effectiveness of this invention, simulation analysis was introduced, using R290 as the refrigerant and a 50% volume fraction ethylene glycol aqueous solution as the coolant. Due to the highly complex internal structure of the water-cooled condenser, including the entire condenser in the simulation would result in a very large mesh size, which current computing power cannot meet. Therefore, the model was reasonably simplified. The simplified simulation model includes: two layers of the first ordinary plate 211 and one layer of the second ordinary plate 212 overlapping each other, forming one refrigerant flow layer 8 and one coolant flow layer 7; the portion of the inlet plate 22 and the outlet plate 23 of the liquid storage chamber near the end of the liquid storage chamber 4; and the lower part of the liquid storage chamber 4 and its inlet and outlet, i.e., the simulated liquid storage chamber 9.

[0040] The geometric model used in the simulation analysis is as follows: Figure 7 , Figure 8 As shown, the refrigerant flows into the refrigerant flow layer 8 from the refrigerant inlet 81 and then flows out from the refrigerant outlet 82; the coolant flows into the coolant flow layer 7 from the coolant inlet 71 and then flows out from the coolant outlet 72; the refrigerant in the simulated liquid storage chamber 94 flows into the liquid storage chamber inlet 91 and then flows out from the liquid storage chamber outlet 92.

[0042]

[0043] In the table: T—Refrigerant temperature (°C).

[0044] Table 2

[0045]

[0046] The material properties used in the simulation are shown in Table 1. The refrigerant is divided into two phases, gas and liquid, and is assigned values ​​using polynomials that vary with temperature. The simulation boundary conditions are designed with reference to experimental data, as shown in Table 2. The mass flow rates of the refrigerant inlet 81 and the liquid storage chamber inlet 91 are the same, which are the mass flow rates of the entire refrigerant inlet pipe 13 of the water-cooled condenser divided by the number of refrigerant layers. The initial temperature of the fluid model is set to be the same as the inlet temperature. The temperatures of the coolant inlet 71 and the refrigerant inlet 81 are set to the inlet temperatures of the coolant and refrigerant of the entire water-cooled condenser, respectively. The temperature of the liquid storage chamber inlet 91 is set to the temperature of the refrigerant outlet pipe 14 of the entire water-cooled condenser when the liquid storage chamber is not added. The temperature of the solid model is set to 60℃.

[0047] Simulation results are as follows Figure 9As shown, the dashed line represents the refrigerant temperature at the inlet of the storage chamber, which is a constant value of 66.8℃, and the solid line represents the average temperature at the outlet 92 of the storage chamber. When the simulation iterations are less than 200, the average temperature at the outlet 92 is mainly affected by the initial conditions. Because the inlet and outlet cross-sectional areas of the simulated storage chamber 9 are relatively small compared to its volume, the refrigerant in the upper layer of the simulated storage chamber 9 does not flow well. Heat is rapidly transferred from the 90℃ high-temperature refrigerant flow layer 8 through the plates to the refrigerant in the simulated storage chamber 9, causing the outlet 92 temperature to rise rapidly from the initial temperature of 66.8℃ to the saturation temperature of 71.73℃. However, as the simulation progresses, the refrigerant in the upper layer of the simulated storage chamber 9 also enters the circulation. Heat cannot accumulate in the simulated storage chamber 9 and is continuously carried away by the flowing refrigerant. The outlet 92 temperature drops below the inlet temperature and eventually stabilizes at 66.5℃. The refrigerant further gains a subcooling of 0.3℃ within the simulated storage chamber 94.

[0048] Figure 10 The simulation results show a temperature field distribution cloud map. Analysis reveals that the high-temperature zone in the simulated liquid storage chamber 94 is located near the refrigerant outlet 82, with a maximum temperature of 67.7℃, while the low-temperature zone is located near the coolant inlet 71, with a minimum temperature of 62.8℃. Unlike the simulation conditions, in a complete water-cooled condenser, the refrigerant flow layer 6 where the liquid storage chamber outlet is located is below the last flow stage. The liquid storage chamber outlet 92 is close to the last flow stage of the refrigerant. Here, the temperature of the refrigerant flow layer 8 is already equal to the storage temperature of the simulated liquid storage chamber 9. Therefore, no temperature distribution cloud map will form near the liquid storage chamber outlet 92. Figure 10 In the localized high-temperature zone, the refrigerant flowing out of the simulated liquid storage chamber 9 will be at a lower temperature.

[0049] Common water-cooled condensers typically have up to 40 layers, with a subcooling requirement of around 3-5°C. As shown in the simulation analysis above, the heat exchange between just one layer of coolant and refrigerant can provide a subcooling of 0.3°C to the refrigerant in the simulated liquid storage chamber 9. Although the heat exchange process in the water-cooled condenser is not a simple additive relationship, it can still be seen that the water-cooled condenser with liquid storage tank function described in this invention can generate a considerable subcooling for the air conditioning system.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
