[0001] This application relates to the field of condensers. Background Technology

[0002] The existing condenser receives gaseous refrigerant from the compressor. The gaseous refrigerant causes energy loss upon entering the condenser, resulting in a decrease in both dynamic and static pressure within the condenser. Summary of the Invention

[0003] Exemplary embodiments of this application can solve at least some of the above-mentioned problems. This application provides a condenser including a housing and an anti-surge assembly. The housing defines a cavity and has a ridge along its axis. The anti-surge assembly is disposed in the cavity and includes a base plate, an arch, a partition assembly, a first side portion, and a second side portion. The base plate is generally horizontal. The arch is located above and connected to the base plate, and has a main ridge extending perpendicular to the housing axis. The partition assembly is located above and connected to the base plate and the arch. The first side portion and the second side portion are disposed on opposite sides of the base plate and on opposite sides of the partition assembly, and are located above and connected to the base plate and the arch. The anti-surge assembly is configured to form at least four flow channels, each flow channel having an inlet and an outlet, thereby allowing fluid entering the condenser to flow from the inlet toward the outlet. In the direction along the housing axis and from the inlet toward the outlet, the cross-sectional area of ​​each of the diversion channels perpendicular to the housing axis gradually increases.

[0004] According to the condenser described above, the inlet is closer to the main ridge than the outlet.

[0005] According to the condenser described above, the partition assembly, the first side, and the second side are configured such that, in the horizontal cross-section of the anti-impact assembly, in the direction along the housing axis and from the inlet toward the outlet, the first side and the partition assembly gradually move away from each other, and the second side and the partition assembly gradually move away from each other.

[0006] According to the condenser described above, the height of the partition assembly gradually decreases along the axis of the housing and in the direction from the inlet toward the outlet.

[0007] According to the condenser described above, the height of the partition assembly is less than the height of the main ridge.

[0008] According to the condenser described above, the partition assembly includes a first partition and a second partition, which are disposed on opposite sides of the main ridge and extend along the axis of the housing. The first partition and the second partition are symmetrically arranged about the main ridge. The first partition can divide the upper space of the bottom plate and the arched portion into a first diversion channel and a second diversion channel, and the second partition can divide the upper space of the bottom plate and the arched portion into a third diversion channel and a fourth diversion channel.

[0009] According to the above condenser, the width L1 of the main ridge, the distance L2 between the first side and the second side at the outlet of the diversion channel, the bottom width L3 of the arch, the distance L4 between the first side and the second side at the outlet of the diversion channel, and the widest width L5 of the partition assembly satisfy the following:

[0010]

[0011] According to the above-described condenser, an inlet pipe is connected to the housing, and a portion of the inlet pipe extends into the cavity. The inlet pipe has a pipe axis, and the anti-impact assembly has a centerline that passes through and is perpendicular to the main ridge. The pipe axis coincides with the centerline.

[0012] According to the condenser described above, the outlet section of the inlet pipe is a diffuser, the inlet of the outlet section is circular, and the outlet of the outlet section is elliptical. The ellipse has mutually perpendicular major and minor radii, and the extension direction of the minor radius is consistent with the axis of the shell.

[0013] Based on the above condenser, the radius r1 of the inlet of the outlet section, the major radius r2 and minor radius r3 of the outlet of the outlet section, and the height H of the outlet section satisfy:

[0014]

[0015] The anti-impact component in the condenser of this application can rectify the gas flowing through the arched section, thereby reducing the generation of eddies and lowering noise. Furthermore, the condenser of this application has a high static pressure recovery coefficient. Attached Figure Description

[0030] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that in the following drawings, the same components are referred to by the same reference numerals.

[0031] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "upper," "lower," "left," "right," "inner," and "outer," are used herein to describe various exemplary structural portions and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed herein can be arranged in different orientations, these terms indicating direction are illustrative only and should not be considered limiting.

[0032] Figure 1 This is a perspective view of the condenser and compressor of this application. (As shown) Figure 1 As shown, the refrigeration system includes a compressor 102 and a condenser 104. The compressor 102 is configured to convert a refrigerant into a gaseous state. The condenser 104 is configured to condense the gaseous refrigerant into a liquid state. Specifically, the compressor 102 has a discharge pipe 112. The gaseous refrigerant can exit the compressor 102 through the discharge pipe 112. The condenser 104 includes an inlet pipe 114, a housing 115, and an outlet pipe 116. The inlet pipe 114 is disposed above the housing 115. The outlet pipe 116 is disposed below the housing 115. The housing 115 defines a cavity 204 (see...). Figure 2 Both inlet pipe 114 and outlet pipe 116 are connected to the housing 115, thereby communicating with the cavity 204. Gaseous refrigerant condenses in the cavity 204 and transforms into liquid refrigerant, which is then discharged through outlet pipe 116.

[0033] Figure 2 yes Figure 1 The diagram shows a vertical sectional view of the condenser 104. Figures 1-2 As shown, the casing 115 is generally a cylindrical shape closed at both ends. It has a casing axis M extending in the left-right direction (i.e., the length direction of the condenser 104). Figure 2As shown, the condenser 104 also includes an anti-impact assembly 214 and several heat exchange tubes 212. The anti-impact assembly 214 and the several heat exchange tubes 212 are disposed in the cavity 204. An inlet pipe 114 is connected to the housing 115, and at least a portion (e.g., the lower end) of the inlet pipe 114 extends into the cavity 204. The inlet pipe 114 is generally a circular pipe having a pipe axis N extending in a vertical direction (i.e., the height direction of the condenser 104). The pipe axis N is generally perpendicular to the housing axis M. The anti-impact assembly 214 is disposed below the inlet pipe 114 and above the several heat exchange tubes 212, so that gaseous refrigerant entering the cavity 204 from the inlet pipe 114 does not directly impact the several heat exchange tubes 212. Each of the several heat exchange tubes 212 extends generally in a horizontal direction (i.e., the length direction of the condenser 104). Several heat exchange tubes 212 are arranged in several rows along the vertical direction (i.e., the height direction of the condenser 104), with multiple heat exchange tubes 212 in each row. In other words, the multiple heat exchange tubes 212 are arranged along the front-back direction (i.e., the width direction of the condenser 104). Thus, when the gaseous refrigerant enters the cavity 204 through the inlet pipe 114, the gaseous refrigerant impacts the anti-impact component 214 and then flows downward through the several heat exchange tubes 212. A heat exchange fluid (not shown) flows in the several heat exchange tubes 212, thereby exchanging heat with the gaseous refrigerant to convert the gaseous refrigerant into a liquid refrigerant.

[0034] Figure 3 yes Figure 2 A perspective view of the anti-impact assembly 214 of the condenser 104 shown. Figure 3 As shown, the anti-impact assembly 214 includes a base plate 302 and an arched portion 304. The base plate 302 is generally flat and is arranged horizontally. The base plate 302 is generally rectangular. The base plate 302 has a center point K. The center point K defines a centerline K1 extending vertically through the center point K. The arched portion 304 is disposed above the base plate 302 and connected to the base plate 302. The arched portion 304 is generally symmetrical from left to right. The arched portion 304 protrudes upward relative to the base plate 302. The arched portion 304 has a main ridge 306 extending in the front-to-back direction (i.e., the width direction of the condenser 104). The main ridge 306 is perpendicular to the housing axis M. In the vertical direction (i.e., the height direction of the condenser 104), the height of the main ridge 306 is higher than the height of the other parts of the arched portion 304. The vertical projection point of the intersection of the main ridge 306 and the centerline K1 coincides with the center point K.

[0035] like Figure 3As shown, the anti-impact assembly 214 also includes a partition assembly 311, a first side portion 332, and a second side portion 334. The partition assembly 311 is located above and connected to the base plate 302 and the arched portion 304. The first side portion 332 and the second side portion 334 are disposed on opposite sides of the base plate 302 and on opposite sides of the partition assembly 311. The first side portion 332 and the second side portion 334 are disposed above the base plate 302 and connected to the arched portion 304 and the base plate 302. The first side portion 332 and the second side portion 334 extend obliquely upward and outward from the base plate 302.

[0036] In this embodiment, the partition assembly 311 includes a first partition 312 and a second partition 314. The first partition 312 and the second partition 314 are disposed on opposite sides of the main ridge 306 and extend along the housing axis M. The first partition 312 and the second partition 314 are generally wedge-shaped. They generally include oppositely facing sidewalls and a top surface located at the top.

[0037] Figure 4A Is it like this? Figure 3 A top view of the anti-impact assembly 214 shown. (See attached image.) Figure 4A As shown, the first partition 312 and the second partition 314 are symmetrically arranged about the main ridge 306, the first side 332 is symmetrically arranged about the main ridge 306, and the second side 334 is symmetrically arranged about the main ridge 306. The first partition 312 is disposed between the first side 332 and the second side 334, dividing the upper space located on one side of the bottom plate 302 and the arched portion 304 into two independent first diversion channels 411 and 412. The second partition 314 is disposed between the first side 332 and the second side 334, dividing the upper space located on the other side of the bottom plate 302 and the arched portion 304 into two independent third diversion channels 413 and 414. Each diversion channel has an inlet 401 and an outlet 402. The partitions and the partition assembly 311 form opposite sides of the diversion channels along the length of the condenser 104. The inlet 401 is closer to the main ridge 306 than the outlet 402. The fluid entering the condenser can flow from inlet 401 toward outlet 402.

[0038] Figure 4B Is it like this? Figure 3 Left view of the anti-impact assembly 214 shown. (See attached image) Figure 4B As shown, the height of the partition assembly 311 is less than the height of the main ridge 306, and the height of the partition assembly 311 gradually decreases along the housing axis M and in the direction from the inlet 401 to the outlet 402. The first side portion 332 and the second side portion 334 gradually move away from each other along the housing axis M and in the direction from the inlet 401 to the outlet 402.

[0039] Figure 4CIt is the anti-impact component 214 in Figure 4A A cross-sectional view along line AA. Figure 4D It is the anti-impact component 214 in Figure 4A A cross-sectional view along line BB. Figure 4E It is the anti-impact component 214 in Figure 4A A cross-sectional view along the CC line. Figure 4F It is the anti-impact component 214 in Figure 4B A cross-sectional view along line DD. Since the first side portion 332 is symmetrically arranged about the main ridge 306, and the second side portion 334 is symmetrically arranged about the main ridge 306, and the first side portion 332 and the second side portion 334 are symmetrically arranged, they will be combined... Figure 4C-4F Taking the portion of the first side portion 332 located on one side of the main ridge 306 as an example, the specific structure of the side portions (i.e., the first side portion 332 and the second side portion 334) will be described. Furthermore, since the first partition portion 312 and the second partition portion 314 are symmetrical with respect to the main ridge 306, they will be combined... Figure 4C-4F Taking the first partition 312 as an example, the specific structures of the first partition 312 and the second partition 314 will be described.

[0040] like Figure 4C-4E As shown, the first side portion 332 includes a first inner side plate 421 and a first outer side plate 422. The first inner side plate 421 is located inside the first outer side plate 422, and the first inner side plate 421 and the first outer side plate 422 are connected at the top. The first inner side plate 421 is inclined, such that the bottom of the first inner side plate 421 is connected to the bottom plate 302 and the arched portion 304. In the direction along the housing axis M and from the inlet 401 toward the outlet 402, the connection point L between the first inner side plate 421 and the bottom plate 302 or the arched portion 304 gradually moves away from the centerline K1. In other words, the inclination angle between the first inner side plate 421 and the centerline K1 gradually decreases. In the direction along the housing axis M and from the inlet 401 toward the outlet 402, the sidewall 432 of the first partition portion 312, which is disposed opposite to the first inner side plate 421, gradually approaches the centerline K1. Therefore, in the direction along the shell axis M and from the inlet 401 toward the outlet 402, the area of ​​the vertical cross-section formed by the first inner side plate 421, the bottom plate 302 or the arched portion 304, and the side wall 432 gradually increases. In other words, in the direction along the shell axis M and from the inlet 401 toward the outlet 402, the cross-sectional area of ​​the diversion channel perpendicular to the shell axis M gradually increases.

[0041] like Figure 4FAs shown, in the horizontal section of the anti-impact assembly 214, in the direction along the housing axis M and from the inlet 401 toward the outlet 402, the first inner side plate 421 and the side wall 432 gradually move away from each other, thereby causing the first side portion 332 and the partition assembly 311 to gradually move away from each other. Similarly, in the horizontal section of the anti-impact assembly 214, in the direction along the housing axis M and from the inlet 401 toward the outlet 402, the second side portion 334 and the partition assembly 311 gradually move away from each other.

[0042] Continue to refer to Figure 4B In the cross-section of the condenser 104 along its width, the width of the main ridge 306 located between the first side portion 332 and the second side portion 334 is L1. The distance between the first side portion 332 and the second side portion 334 at the outlet of the diversion channel is L2. In other words, the farthest distance between the tops of the first side portion 332 and the second side portion 334 is L2. The bottom width of the arched portion 304 is L3. In other words, the minimum width of the bottom plate 302 is L3. The distance between the first side portion 332 and the second side portion 334 at the outlet of the diversion channel is L4. In other words, the farthest distance between the bottoms of the first side portion 332 and the second side portion 334 is L4. The widest width of the partition assembly 311 is L5. In other words, the top width of the partition assembly 311 located between the inlets of the diversion channel is L5. The above L1-L5 satisfy:

[0043]

[0044] Figure 5A Is it like this? Figure 1 A perspective view of the inlet pipe 114 and the anti-impact assembly 214 shown. Figure 5B yes Figure 5A A vertical sectional view of the inlet pipe 114 and the anti-impact assembly 214. (See attached image.) Figures 5A-5B As shown, the inlet pipe 114 has a pipe axis N. The anti-impact assembly 214 has a centerline K1. The pipe axis N and the centerline K1 coincide (i.e., are coaxially arranged), so that the fluid entering from the inlet pipe 114 can impact the main ridge 306 and enter the various branch channels from the channel inlet.

[0045] like Figures 5A-5B As shown, the inlet pipe 114 includes a first section 512 and a second section 514 connected to each other. The first section 512 is disposed on the outside of the housing 115 (see Figure 114). Figure 1 The second segment 514 is located in cavity 204 (see...). Figure 2In the first section 512 and the upper part of the second section 514 are both circular pipes with a radius of r1. The lower part of the second section 514 forms the outlet section 500, which is a gradually expanding pipe. The height of the outlet section 500 is H. The inlet 502 of the outlet section 500 is circular and serves as the outlet of the first section 512. The outlet 504 of the outlet section 500 is elliptical. The transition from inlet 502 to outlet 504 is smooth.

[0046] Figure 5C This is a sectional view of exit 504 of exit section 500 in its plane. (Example) Figure 5C As shown, the major and minor radii of outlet 504 are r2 and r3, respectively. The extension direction of the major radius r2 is consistent with the width direction of condenser 104, and the extension direction of the minor radius r3 is consistent with the direction of the shell axis M. The height H, the radius r1 of inlet 502, the major radius r2, and the minor radius r3 satisfy the following:

[0047]

[0048] The inventors of this application have discovered that existing anti-impact components reduce both the dynamic and static pressure of the refrigerant. The inventors have also discovered that some existing anti-impact components include arched sections intended to guide gas movement; however, the airflow passing over these arched sections generates eddies, thus causing noise.

[0049] Figure 6 This is a simulation diagram of gas flow within the anti-impact component of this application. (Example:) Figure 6 As shown, the gas flow is divided into two streams after passing through the arch 304, and each stream is further divided into two branches due to the presence of the dividing assembly 311. Each branch flows from the inlet 401 to the outlet 402 in each branch channel. In the branch channels, the flow velocity of each branch is slowed down and diffused because the cross-sectional area of ​​the branch channel perpendicular to the housing axis gradually increases along the direction from the inlet 401 to the outlet 402. The dividing assembly 311 can rectify the gas flowing through the arch 304, thereby reducing the generation of eddies and lowering noise.

[0050] The inventors of this application have discovered that existing anti-impact components, including arched portions, have a certain static pressure recovery effect. For example, when static pressure is fully recovered, the static pressure recovery coefficient of the prior art is approximately 75.3% when it is 100%. In this application, because the extension direction of the major radius r2 of the ellipse is consistent with the width direction of the condenser 104, and the extension direction of the minor radius r3 is consistent with the direction of the shell axis M, the airflow can be guided to distribute more along the width direction of the condenser 104 to enter the diversion channel, thereby increasing the static pressure recovery coefficient. In one embodiment, the static pressure recovery coefficient of the condenser of this application can reach 92.1%.

[0051] In other embodiments, a connecting member may be provided on the top surface of the partition assembly 311 to connect with the housing 115, thereby enhancing the reliability of the shock-absorbing assembly 214 in the housing 115.

[0052] In the embodiments of this application, compressor 102 is shown as a centrifugal compressor, but those skilled in the art will understand that other types of compressors are also within the scope of protection of this application.

[0053] In embodiments of this application, the separating component 311 includes a first separating portion 312 and a second separating portion 314, which cooperate with the first side portion 332 and the second side portion 334 to form four diversion channels. However, in other embodiments, the separating component 311 may include multiple separating portions to form more diversion channels.

[0054] Although this disclosure has been described in conjunction with examples of the embodiments outlined above, various alternatives, modifications, variations, improvements, and / or substantially equivalents, whether known or currently or soon to be foreseen, will likely be apparent to those skilled in the art. Furthermore, the technical effects and / or technical problems described herein are exemplary and not limiting; therefore, the disclosures herein may be used to solve other technical problems and have other technical effects and / or can solve other technical problems.
