Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an evaporating tube, an evaporator and air conditioning equipment. Background Art

[0002] The evaporator tube is a heat exchange tube used in the evaporator. Its performance directly affects the performance of the evaporator, and further affects the performance of the air-conditioning equipment using the evaporator.

[0003] When working, the refrigerant flows outside the evaporator tube and absorbs the heat of the heat exchange medium inside the evaporator tube to evaporate. According to the bubble dynamics theory, only when the temperature of the outer wall of the evaporator tube is higher than the evaporation temperature of the refrigerant, the liquid refrigerant can evaporate into gaseous refrigerant. This is called wall superheat. The greater the wall superheat, the more intense the evaporation.

[0004] In the related art, the temperature of the outer wall of the evaporator tube continuously decreases along the flow direction of the heat exchange medium, while the evaporation temperature of the refrigerant generally remains unchanged, which causes the wall superheat to continuously decrease in the flow direction of the heat exchange medium, thereby causing the evaporation intensity in this direction to weaken, that is, the heat exchange intensity outside the evaporator tube continuously decreases in the flow direction of the heat exchange medium. Summary of the invention

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of the present invention.

[0059] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0060] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0061] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] In air-conditioning equipment, the evaporator works together with the compressor, condenser and expansion valve to regulate and control the indoor temperature.

[0063] The evaporator heats the refrigerant by absorbing heat from the heat exchange medium. In some cases, when the evaporator is working, the refrigerant flows outside the evaporation tube (i.e., the heat exchange tube for the evaporator) and exchanges heat with the heat exchange medium (such as water or air) located inside the evaporation tube, absorbing the heat of the heat exchange medium, and changes from liquid to gas, thus realizing the evaporation process.

[0064] In the process of practicing the present invention, the inventors found that in the related art, the temperature of the outer wall of the evaporator tube continuously decreases along the flow direction of the heat exchange medium used for heat exchange with the refrigerant, while the evaporation temperature of the refrigerant generally remains unchanged. In this case, the wall superheat continuously decreases in the flow direction of the heat exchange medium, resulting in the continuous weakening of the heat exchange intensity of the evaporator tube in the flow direction of the heat exchange medium, affecting the heat exchange performance of the evaporator tube and the heat exchanger and air conditioning equipment including the evaporator tube. Among them, the wall superheat refers to the degree to which the outer wall temperature of the evaporator tube is higher than the evaporation temperature of the refrigerant. The greater the wall superheat, the more intense the evaporation and the better the heat exchange performance.

[0065] Taking a large central air-conditioning water-cooled unit as an example, the heat exchange medium is water, and the flow direction of the heat exchange medium is the direction of the water flow. In the relevant technology, the outer wall temperature of the evaporator tube continuously decreases in the direction of the water flow. Under the national standard working conditions, the water inlet is generally 12°C and the water outlet is 7°C, while the refrigerant evaporation temperature generally remains unchanged at around 5.5°C, which causes the wall superheat to continuously decrease in the direction of the water flow, thereby causing the evaporation intensity of the evaporator tube to continuously weaken in the direction of the water flow, affecting the heat exchange performance.

[0066] Based on the above findings, the present invention optimizes the structure of the evaporator tube to improve the heat exchange performance of the evaporator tube, the evaporator and the air-conditioning equipment.

[0067] Figure 1-7 The evaporation tube of the present invention is shown as an example.

[0068] Reference Figure 1-7 In the present invention, the evaporation tube 10 includes a tube body 1 and outer fins 2, etc.

[0069] The tube body 1 is a hollow rotating body structure, such as a hollow cylinder, and the first end and the second end of the tube body 1 along the axial direction are both open to allow the heat exchange medium used for exchanging heat with the refrigerant to flow through the inside of the tube body 1.

[0070] It can be understood that the axial direction, circumferential direction and radial direction of the tube body 1 are the axial direction, circumferential direction and radial direction of the evaporation tube 10. Figure 1 The coordinate axis Z is used in the figure, and the circumference of the tube body 1 is Figure 1 It is represented by the coordinate axis T.

[0071] The outer fins 2 are arranged on the outer wall of the tube body 1 and protrude outward from the outer wall of the tube body 1, which can increase the heat exchange area of ​​the outer wall, strengthen evaporation heat transfer, improve heat exchange efficiency, and thus improve energy utilization and save energy. It is an effective means of strengthening the outer tube.

[0072] Reference Figure 1-4 as well as Figure 7 The outer wing 2 includes a plurality of wing segments 21 arranged in sequence along the axial direction of the tube body 1. The number and thickness of the wing segments 21 are not limited. In some embodiments, 30-60 wing segments 21 are arranged per inch in the axial direction of the tube body 1, for example, 52 wing segments 21 are arranged per inch. In some embodiments, the thickness H1 of the wing segment 21 is 0.4-1.0 mm, for example, 0.6 mm. The thickness H1 of the wing segment 21 refers to the height of the wing segment 21 protruding outward from the outer wall of the tube body 1. It is not difficult to understand that the thickness of the wing segment 21 is actually the thickness of the outer wing 2.

[0073] In some embodiments, the outer wing 2 is spirally arranged on the tube body 1, and each wing segment 21 is a portion of the outer wing 2 corresponding to each pitch. Specifically, in some embodiments, the spiral angle between the outer wing 2 and the axis of the tube body 1 is 75°-85°, for example 82°.

[0074] Continue to refer to Figure 1-4 as well as Figure 7 In some embodiments, among the plurality of fin segments 21, a first evaporation chamber 22 is provided between any two adjacent fin segments 21, and along the direction from the first end to the second end of the tube body 1 axially (in Figure 4 In other words, in the direction from the first end to the second end of the tube body 1 axially, the depth H4 of each first evaporation chamber 22 is smaller than the depth H4 of the downstream adjacent first evaporation chamber 22.

[0075] Among them, Figure 7As shown, the first evaporation chamber 22 includes a first chamber 221 and a second chamber 222. The first chamber 221 is connected to the outside of the evaporation tube 10 through the second chamber 222, and the flow area of ​​the second chamber 222 is smaller than the flow area of ​​the first chamber 221. Based on this, the first evaporation chamber 22 is constructed as a semi-closed evaporation chamber structure, which becomes the vaporization core, so that the refrigerant can evaporate continuously in the first evaporation chamber 22, and the bubbles cause violent disturbances when they are formed, grow and detach from the heated wall, effectively enhancing the heat exchange. It can be seen that setting the first evaporation chamber 22 between two adjacent wing sections 21 is an effective enhancement method, which can further enhance the heat exchange.

[0076] Furthermore, each first evaporation chamber 22 is constructed to increase in depth H4 in the direction from the first end to the second end of the tube body 1 in sequence, so that the thermal resistance of the evaporation tube 10 can be gradually reduced in the direction from the first end to the second end of the tube body 1 in the axis direction, thereby effectively increasing the outer wall temperature of the evaporation tube 10 in the corresponding part and increasing the wall superheat degree of the evaporation tube 10 in the corresponding part. In this way, during operation, it is only necessary to make the heat exchange medium flow in the direction from the first end to the second end of the tube body 1 in the axis direction, so as to effectively reduce the attenuation of the heat exchange intensity of the evaporation tube 10 in the flow direction of the heat exchange medium, thereby effectively improving the heat exchange performance of the evaporation tube 10.

[0077] In addition, in order to further enhance heat exchange and improve heat exchange performance, the present invention also makes other improvements to the evaporation tube 10.

[0078] As one of the improvements, refer to Figure 1-4 and Figure 7 In some embodiments, at least one wing segment 21 is provided with a second evaporation chamber 23. Figure 4 and Figure 7 The second evaporation chamber 23 is located between two adjacent first evaporation chambers 22, and includes a third chamber 231 and a fourth chamber 232. The third chamber 231 is connected to the outside of the evaporation tube 10 through the fourth chamber 232, and the flow area of ​​the fourth chamber 232 is smaller than the flow area of ​​the third chamber 231. In this way, the second evaporation chamber 23 is also constructed as a semi-enclosed evaporation chamber structure, which becomes a vaporization core and plays a role in enhancing heat exchange.

[0079] By further providing the second evaporation chamber 23 on the basis of the first evaporation chamber 22 , the density of the evaporation chamber can be increased, thereby more effectively enhancing heat exchange.

[0080] More specifically, refer to Figure 4 and Figure 7In some embodiments, the wing segment 21 includes at least two wing bodies 21a arranged at intervals along the axial direction of the tube body 1, each wing body 21a includes a body portion 211 and a head portion 212, the head portion 212 is connected to the top of the body portion 211 (and the end of the body portion 211 away from the outer wall of the tube body 1) and protrudes to both sides of the axial direction of the tube body 1 relative to the body portion 211. At this time, the first evaporation chamber 22 is located between adjacent wing bodies 21a of two adjacent wing segments 21, and the second evaporation chamber 23 is located between two adjacent wing bodies 21a on the same wing segment 21. In other words, the first evaporation chamber 22 is the interval between adjacent wing bodies 21a of two adjacent wing segments 21, wherein the interval between adjacent main bodies 211 of two adjacent wing segments 21 is the first chamber 221, and the interval between adjacent heads 212 of two adjacent wing segments 21 is the second chamber 222; the second evaporation chamber 23 is the interval between two adjacent wing bodies 21a on the same wing segment 21, wherein the interval between two adjacent main bodies 211 on the same wing segment 21 is the third chamber 231, and the interval between two adjacent heads 212 on the same wing segment 21 is the fourth chamber 232. Since the head 212 protrudes toward both axial sides of the tube body 1 relative to the main body 211, the flow area of ​​the first chamber 221 is greater than the flow area of ​​the second chamber 222, and the flow area of ​​the third chamber 231 is greater than the flow area of ​​the fourth chamber 232.

[0081] The number of wing bodies 21a in each wing segment 21 is not limited. Figure 7 In some embodiments, the wing segment 21 includes three wing bodies 21a arranged along the axial direction Z. At this time, each wing segment 21 is provided with two second evaporation chambers 23 arranged at intervals along the axial direction Z, which can effectively increase the density of the evaporation chambers while still ensuring that the wing segment 21 has greater strength.

[0082] In some embodiments, the width B of each body portion 211 is equal. For example, the width B of each body portion 211 is 0.1-0.5 mm. Specifically, in some embodiments, the width B of each body portion 211 is 0.2 mm. At this time, the adjacent evaporation chambers, including the adjacent second evaporation chambers 23, and the second evaporation chamber 23 and the adjacent first evaporation chamber 22, are equally spaced in the axial direction. It can be understood that the width refers to the dimension along the axial direction Z of the tube body.

[0083] In some embodiments, the spacing L between adjacent body parts 211 is equal. For example, the spacing L between adjacent body parts 211 is 0.05-0.2 mm. Specifically, in some embodiments, the spacing L between adjacent body parts 211 is 0.1 mm. At this time, the widths of each first chamber 221 and each third chamber 231 are equal.

[0084] In some embodiments, the depth H2 of the portion of the second evaporation chamber 23 located below the head 212 (i.e., the side of the head 22 close to the tube body 1) is 0.2-0.8 times the thickness H1 of the wing segment 21. For example, the depth H2 of the portion of the second evaporation chamber 23 located radially inward of the head 212 is 0.5 times the thickness H1 of the wing segment 21. Figure 7 It can be seen that the depth H2 of the portion of the second evaporation chamber 23 located below the head 212 is actually the depth of the third chamber 231, or the height of the body 211. That is, in these embodiments, the depth of the third chamber 231 (the height of the body 211) is 0.2-0.8 times the thickness H1 of the wing section 21, and specifically can be 0.5 times.

[0085] Reference Figure 6 In some embodiments, the head 212 is in an oblique elliptical shape to facilitate processing and to facilitate the arrangement of more evaporation chambers to increase the density of the evaporation chambers. Of course, in other embodiments, the head 212 may also be in other shapes such as a rectangle or a circle.

[0086] In some embodiments, the thickness H3 of the head 212 is 0.05-0.2 mm, for example, 0.08 mm.

[0087] Depend on Figure 4 and Figure 7 It can be seen that the sum of the thickness H3 of the head 212 and the depth H2 of the portion of the second evaporation chamber 23 located below the head 212 is the depth H5 of the second evaporation chamber 23. Figure 4 and Figure 7 In some embodiments, the depth H5 of the second evaporation chamber 23 is less than the depth H4 of the first evaporation chamber 22 located downstream of the second evaporation chamber 23 and adjacent to the second evaporation chamber 23 in the direction from the first end to the second end of the axial direction of the tube body 1. In other words, the second evaporation chamber 23 of each wing segment 21a has a smaller depth dimension than the downstream adjacent first evaporation chamber 22. In this way, the outer wing 2 has a higher strength than the case where the depth of the second evaporation chamber 23 is equal to or greater than the depth of the downstream adjacent first evaporation chamber 22.

[0088] In addition, refer to Figure 4 In some embodiments, the depths H5 of the second evaporation chambers 23 on the outer wing 2 are equal. In this case, the structure is simpler and the processing is convenient.

[0089] However, as a variation, in some other embodiments, the depth H5 of each second evaporation chamber 23 on the outer wing 2 may also be unequal. For example, in some embodiments, the depth H5 of each second evaporation chamber 23 increases successively along the direction from the first end to the second end of the tube body 1 axially. In this way, not only the depth of the first evaporation chamber 21 increases successively along the direction from the first end to the second end of the tube body 1 axially, but also the depth of the second evaporation chamber 23 increases successively along the direction from the first end to the second end of the tube body 1 axially, so that the evaporation chamber of the outer wing 2 as a whole increases in depth successively along the direction from the first end to the second end of the tube body 1 axially. When the flow direction of the heat exchange medium is along the direction from the first end to the second end of the tube body 1 axially, the attenuation of the wall superheat can be more effectively reduced, thereby being able to more effectively improve the heat exchange performance of the evaporator tube 10.

[0090] In some embodiments, each evaporation chamber may be formed by extrusion.

[0091] In addition to further providing the second evaporation chamber 23, other methods may be used to further improve the heat exchange performance.

[0092] For example, refer to Figure 2 and Figure 5 In some embodiments, the evaporation tube 10 further includes a groove 4 disposed in the first evaporation chamber 22. The groove 4 disposed in the first evaporation chamber 22 can also form a vaporization core. Therefore, on the basis of the first evaporation chamber 22, further providing the groove 4 can increase the density of the vaporization core, thereby further improving the heat exchange performance.

[0093] Among them, refer to Figure 2 In some embodiments, the groove 4 is disposed on the bottom wall of the first evaporation chamber 22. Compared with the case where the groove 4 is disposed on the side wall of the first evaporation chamber 22, the groove 4 is disposed on the bottom wall of the first evaporation chamber 22, which is easier to process.

[0094] There is no limit to the number of grooves 4. For example, in some embodiments, multiple groups of grooves 4 are provided along the length direction of the first evaporation chamber 22, and one, two or more grooves 4 may be provided in each groove 4. The length of the first evaporation chamber 22 refers to the dimension of the first evaporation chamber 22 along the circumferential direction T of the tube body 1, so the length direction of the first evaporation chamber 22 is actually the circumferential direction T of the tube body 1.

[0095] For another example, in some embodiments, the evaporator tube 10 further includes an inner tooth 3, which is disposed on the inner wall of the tube body 1. The inner tooth 3 includes a plurality of inner tooth portions 31 sequentially arranged along the tube body 1. For example, in some embodiments, the inner tooth 3 includes 30-60 inner tooth portions 31 spaced apart along the axial direction of the tube body 1.

[0096] The inner teeth 3 can increase the heat exchange area of ​​the inner wall of the evaporation tube 10, thereby enhancing the evaporation heat transfer, and are an effective means of strengthening the tube.

[0097] The inner teeth 3 may also be spirally arranged on the inner wall of the tube body 1 .

[0098] In summary, the present invention can solve the problem of large attenuation of the heat exchange intensity outside the evaporator tube in the flow direction of the heat exchange medium by optimizing the structure of the evaporator tube 10, effectively improve the heat exchange performance of the evaporator tube 10, and further improve the heat exchange performance of the evaporator and the air-conditioning equipment.

[0099] In addition, in the present invention, a large amount of material is removed from the evaporation tube 10 , which is also beneficial to reducing the weight of the evaporation tube 10 and achieving a lightweight design.

[0100] The above description is only an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
