Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. The plurality described in this application includes two and more. When two parts are connected in this application, the lumens of the two parts are also in communication with each other. For example, the collecting pipe and the heat exchange pipe are both provided with inner cavities for circulating heat exchange media, and when the collecting pipe and the heat exchange pipe are connected with each other, the inner cavities of the collecting pipe and the heat exchange pipe are communicated.
In the case of no conflict, the various embodiments in the present application may complement each other.
FIG. 1 is an exploded view of a heat exchanger shown in an exemplary embodiment; fig. 2 is a schematic structural view of the connection of the heat exchange tube, the header and the heat exchange member in fig. 1. As shown in fig. 1 and 2, the heat exchanger includes a header 1, a heat exchange tube 2, a heat exchange member 3, and a housing 8. The heat exchange component 3 can be an integral structure contacting with the plurality of heat exchange tubes 2, or can be a plurality of sectional materials arranged on the heat exchange tubes 2 at intervals, which will be described in detail later. Wherein, a heat exchange space 81 is formed in the outer shell 8, and the heat exchange tubes 2 are flat tubes and at least partially accommodated in the heat exchange space 81. The header 1 may be disposed in the heat exchange space 81, but certainly, may not be disposed therein, and the present application is not limited thereto.
The housing 8 includes a top wall 82, a bottom wall 83, and a side wall 84 connected between the top wall 82 and the bottom wall 83. The side wall 84 is used to connect the top wall 82 and the bottom wall 83 to enclose the heat exchanging space 81, and the housing 8 may be a rectangular parallelepiped in this embodiment. The top wall 82, the bottom wall 83 and the side wall 84 may be separated from each other, or may be partially integrated with each other, which is not limited in this embodiment. The bottom wall 83 is provided with a first through hole 831, and the top wall 82 is provided with a second through hole 821. The top wall 82 and the bottom wall 83 may be iron sheets in a straight plate shape, and the first through hole 831 and the second through hole 821 may be mesh holes formed in the iron sheets. In general, the direction of the connection line between the first through hole 831 and the second through hole 821 is substantially the same as the air flowing direction, so as to facilitate the air flowing.
The heat exchange tube 2 exchanges heat with air to form ascending convection, the air enters from the first through hole 831, ascends through the heat exchange space 81 and then flows out from the second through hole 821; wherein heat exchange of the heat exchange tubes 2 with air is accomplished in the heat exchange space 81. Since the housing 8 can shield an external air flow, it is possible to form a stable air ascending convection to the air heat-exchanged with the heat exchange pipe 2, the heat transfer resistance of the heat exchange pipe 2 to the air is reduced, and thus the heat exchange effect of the heating heat exchanger to the air can be improved. Meanwhile, the heat exchange tube 2 directly exchanges heat with air, the heat transfer temperature difference between the heat exchange tube and the air is larger, the air flow rate is increased, and the heat exchange capacity of the heating heat exchanger can be further improved.
Further, the side walls 84 include front and rear side walls 841 and 842 at the front and rear of the heat exchange tube 2, and partial side walls at the left and right ends of the heat exchange tube 2. The heat exchange tube 2 is in contact with the front sidewall 841 in order to increase the temperature of the front sidewall 841, thereby increasing the radiation heat-dissipating capacity of the front sidewall 841. In this embodiment, in order to make the front sidewall 841 better contact with the heat exchange tube 2, some protrusions 843 facing the heat exchange tube 2 may be pressed on the front sidewall 841, the protrusions 843 being adapted to contact at least a portion of the heat exchange tube 2 and making the housing 3 more aesthetic. In addition, when the heat exchange tube 2 is in contact with the rear sidewall 842, the inventor finds that the temperature of the rear sidewall 842 increases due to the contact of the heat exchange tube 841 and the rear sidewall 842, which causes a heat dead angle problem at the wall gap, and heat loss and heat waste due to the failure of good heat transfer with air. A space gap is formed between the heat exchange tube 2 and the rear sidewall 842, so that a heat dead angle can be eliminated. A heat exchange component 3 (detailed later) can be arranged between the heat exchange tube 2 and the front side wall 841 and the rear side wall 842, the arranged heat exchange component 3 can be in contact with the front side wall 841 or the rear side wall 842, the heat exchange component 3 and two side walls (841/842) can conduct heat, and the radiation heat dissipation capacity is improved. Of course, the heat exchange member 3 may not be in contact with the both side walls (841/842), and the housing 8 is used only for forming the heat exchange space 81.
With reference to fig. 1 and fig. 2, in an embodiment of the first aspect of the present application, a plurality of heat exchange tubes 2 for flowing a heat exchange medium are connected to the collecting main 1, and the heat exchange tubes 2 are arranged along an axial direction of the collecting main 1 and may form a plurality of rows. The heat exchange tube 2 may be a flat tube having a microchannel in which a heat exchange medium flows, at least two flow channels extending in the length direction of the flat tube are provided inside the microchannel flat tube, the cross section of each flow channel may be quadrilateral (for example, but not limited to rectangular, trapezoidal), circular, elliptical, triangular, or may be generally quadrilateral, circular, elliptical, or triangular with serrations. The heat exchange medium may be water or a refrigerant (e.g., a fluorine-containing refrigerant).
The collecting pipe 1 comprises a first collecting pipe 10 and a second collecting pipe 15, and the heat exchange pipe 2 comprises a first heat exchange pipe 21, a second heat exchange pipe 22 and a reversing part 24. A first end (a left end shown in fig. 2) of the first heat exchange tube 21 is connected to the first collecting pipe 10, a first end (a left end shown in fig. 2) of the second heat exchange tube 22 is connected to the second collecting pipe 15, and the first heat exchange tube 21 and the second heat exchange tube 22 are fixed by a fixing bracket 14. A second end (a right end shown in fig. 2) of the first heat exchange tube 21 is connected with a second end (a right end shown in fig. 2) of the second heat exchange tube 22 through a reversing part 24, and inner cavities of the first heat exchange tube 21, the second heat exchange tube 22 and the reversing part 24 are communicated to circulate a heat exchange medium. The first heat exchange tube 21, the second heat exchange tube 22 and the reversing part 24 may be integrally formed flat tubes, or may be separate flat tube structures.
The first heat exchange tube 21 and the second heat exchange tube 22 are arranged oppositely and in parallel and are flat tubes. As shown in fig. 2, the first heat exchange tubes 21 and the second heat exchange tubes 22 are arranged at intervals along the axial direction of the collecting main 1, and the surfaces of the first heat exchange tubes 21 and the second heat exchange tubes 22, which are in contact with the heat exchange component 3, are parallel to the axial direction of the collecting main 1, that is, in the up-down direction in fig. 2. An accommodating space 23 is formed between the first heat exchange tube 21 and the second heat exchange tube 22. One end of the accommodating space 23 is adjacent to the second through hole 821, and the other end is adjacent to the first through hole 831. A set of the heat exchange components 3 (a set of the heat exchange components may be fins of an integral structure shown in fig. 3, or an assembly composed of a plurality of profiles in fig. 4) is disposed in the accommodating space 23, and a contact surface of the heat exchange component 3 is at least partially in contact with a heat transfer surface of the first heat exchange tube 21 and the second heat exchange tube 22 (the heat transfer surface is a surface in contact with the heat exchange component 3 and mainly used for conducting heat with the heat exchange component 3). Wherein the contact surface of the heat exchange member 3 is a surface facing the first heat exchange tube 21 or the second heat exchange tube 22, and is capable of heat transfer in contact with the heat transfer surface. One contact surface of the heat exchange member 3 is in contact with the first heat exchange tube 21, and the other contact surface of the heat exchange member 3 is in contact with the second heat exchange tube 22. The first heat exchange tube 21 and the second heat exchange tube 22 can simultaneously transfer heat to the heat exchange component 3, so that the temperature of the heat exchange component 3 is higher than the temperature of heat transfer with a single heat exchange tube, and after the heat transfer temperature difference between the heat exchange component 3 and air is increased, the flow rate of the air is correspondingly increased, and the heat transfer resistance between the heat exchange component 3 and the air is reduced. Therefore, the heat exchange efficiency of the heating heat exchanger can be improved, a better radiation heat release effect can be achieved, and the heat exchange capacity of the heating heat exchanger is further improved.
The heat exchange component 3 can be made of metal materials such as aluminum alloy and iron, and is in various shapes to increase the heat exchange area. The cross section of the heat exchange member 3 (the cross section refers to the cross section of the heat exchange member 3) may be rectangular wave-shaped, sinusoidal wave-shaped, or triangular wave-shaped. The heat exchanging part 3 can divide at least part of the accommodating space 23 into a heat exchanging channel 31 for air to flow, and the air stably rises in the heat exchanging channel 31 and exchanges heat with the heat exchanging part 3. The structure of the heat exchange member 3 will be described below with reference to two embodiments shown in fig. 3 and 4, but the structure of the heat exchange member 3 is not limited to the following embodiments.
As shown in fig. 3, the heat exchange component 3 is a rectangular wave, is a fin 32, and can be formed by bending, and can be fixed with the first heat exchange tube 21 and the second heat exchange tube 22 by brazing, interference fit, clamping, or the like. For example, the wave crests of the heat exchange member 3 are fixed to the surface of the first heat exchange tube 21, and the wave troughs of the heat exchange member 3 are fixed to the surface of the second heat exchange tube 22. The heat exchange member 3 contacts the first heat exchange tube 21 and the second heat exchange tube 22 in the arrangement direction (up-down direction in fig. 2) and the left-right direction (see fig. 2) thereof.
The fin 32 has at least two side walls 321, a top wall 322 and a bottom wall 323. A heat exchange channel 31 is formed between two adjacent side walls; the top wall 322 connects one ends of the adjacent two side walls 321, and the bottom wall 323 connects the other ends of the adjacent two side walls 321. The top wall 322 and the bottom wall 323 are alternately arranged, so that the top wall 322 can connect two adjacent side walls 321, and the bottom wall 323 can connect two adjacent side walls 321; wherein the two side walls 321 connected by the top wall 322 and the bottom wall 323 share one of the side walls 321. The top wall 322 has a top end face 324 and the bottom wall 323 has a bottom end face 325. The top end surface 324 and the bottom end surface 325 can be used as two contact surfaces of the heat exchange component 3 to contact with the first heat exchange tube 21 or the second heat exchange tube 22 for heat transfer. The top end face 324 can be in contact with the first heat exchange tube 21 and the bottom end face 325 can be in contact with the second heat exchange tube 22. Of course, it is also possible that the top end face 324 is in contact with the first heat exchange tube 21 and the bottom end face 325 is not in contact with the second heat exchange tube 22; or the top end face 324 is not in contact with the first heat exchange tube 21 and the bottom end face 325 is in contact with the second heat exchange tube 22.
As shown in fig. 4, the heat exchange component 3 is a profile 33 disposed at an interval, and the profile 33 may be fixed to the first heat exchange tube 21 and the second heat exchange tube 22 by mechanical connection such as clamping, fixing, etc., or may be fixed by welding. The profile 33 may be arranged along the arrangement direction of the first heat exchange tube 21 or the second heat exchange tube 22 (in the vertical direction in fig. 4, the plurality of first heat exchange tubes 21 or the plurality of second heat exchange tubes 22 are arranged at intervals in the vertical direction), and the length of the profile 33 may be determined according to the requirement, and one profile 33 may be arranged along the arrangement direction to contact all the first heat exchange tubes 21 or the second heat exchange tubes 22, or a plurality of combinations (the length of the plurality of combinations is equivalent to the arrangement length of the heat exchange tubes, and may be slightly longer or slightly shorter) may contact the first heat exchange tubes 21 or the second heat exchange tubes 22 in the arrangement direction. The profiles 33 are arranged on the first heat exchange tube 21 or the second heat exchange tube 22 at intervals along the length direction (left-right direction) of the first heat exchange tube 21 or the second heat exchange tube 22.
In an embodiment, the profile 33 includes a base 331, and extensions 332 extending from two opposite sides of the base 331 toward a direction away from the base 331, where the extensions 332 serve as heat exchange surfaces for performing a primary heat exchange with air. The substrate 331 is used for contacting the first heat exchange tube 21 or the second heat exchange tube 22, and can penetrate through a gap between two adjacent first heat exchange tubes 21 or second heat exchange tubes 22 through a fixing member such as a rivet and connect the symmetrically arranged profiles 33 positioned at two sides of the first heat exchange tube 21 or the second heat exchange tube 22. The section bar 33 can also be asymmetrically arranged, and the clamping pieces such as buckles are arranged on the section bar 33 to be fixed on the first heat exchange tube 21 and the second heat exchange tube 22 in a clamping manner. In this embodiment, the inside of the profile 33, that is, two adjacent extension portions 332 may surround the heat exchange channel 31, along the arrangement direction of the profile 33, the heat exchange channel 31 (a space with a distance Y surrounded by the extension portions 332 of two adjacent profile 33) may also be formed between two adjacent profile 33, a plurality of profile 33 forms a set of the heat exchange component 3, and at least part of the accommodating space 23 (see fig. 1) is divided into a plurality of heat exchange channels 31.
In the embodiment shown in fig. 4, the section of the profile 33 is open, and in other embodiments, the section of the profile 33 may be closed, for example, the section of the profile 33 is a closed rectangle. That is, the profile 33 may have different shapes, so as to have good heat transfer with the first heat exchange tube 21 and the second heat exchange tube 22. As described above, the heat exchange member 3 is in contact with the first and second heat exchange pipes 21 and 22 to transfer heat, and exchanges heat with air. The sectional material 33 is adopted as the heat exchange component 3, so that the connection with the heat exchange tube is convenient, the brazing can be replaced by a mechanical connection mode, and the processing cost can be saved. In addition, compare in the fashioned specific heat transfer part 3 of bending, the section bar need not the processing of carelessness, can directly use, has the advantage of convenient for acquireing. On the basis of ensuring a certain heat exchange channel, the use amount of the heat exchange component 3 can be reduced, and the production cost is reduced. Meanwhile, the available types of the heat exchange components 3 can be selected more, and the heat exchange components 3 matched with the heat exchange tubes do not need to be directly produced.
Further, in the embodiment shown in fig. 1, a set of the heat exchange members 3 is disposed between the first heat exchange tube 21 and the second heat exchange tube 22. In order to increase the heat transfer area, and the area of the heat exchange channel 31 (see fig. 1), two or more sets of the heat exchange members 3 may be provided. As shown in fig. 4, two sets of the heat exchange members 3 using the sectional materials 33 are disposed in the accommodating space 23 between the first heat exchange tube 21 and the second heat exchange tube 22. One set of the base 331 side of the profile 33 is disposed in contact with the first heat exchange tube 21, and the other set of the base 331 side of the profile 33 is disposed in contact with the second heat exchange tube 22. The two sets of profiles 33 may be in contact with each other, may be arranged at a distance from each other, may be symmetrical, or may be asymmetrical. Or as shown in fig. 5, two sets of fins 32 are arranged in the accommodating space 23 between the first heat exchange tube 21 and the second heat exchange tube 22 to form the heat exchange component 3. The top wall 322 of one set of the heat exchange component 3 is in contact with the first heat exchange tube 21, the top wall 322 of the other set of the heat exchange component 3 is in contact with the second heat exchange tube 22, and the two sets of the heat exchange components 3 may be in contact with each other, may also be arranged at a certain distance, may be symmetrical, may also be asymmetrical.
In addition, the first heat exchange tube 21 and the second heat exchange tube 22 may be provided with an external heat exchange member 4 on one side close to the shell 8, so that the heat exchange area can be further increased, and the heat exchange capacity of the heating heat exchanger can be enhanced. As shown in fig. 6, the external heat exchange component 4 and the heat exchange component 3 may have the same or different structures. For example, the heat exchange component 3 and the external heat exchange component 4 both use fins 32 with a cross section (the cross section is a cross section perpendicular to the axial direction of the collecting pipe) in a rectangular corrugated shape, a sine wave shape or a triangular wave shape; or the heat exchange part 3 adopts a fin 32 with a rectangular corrugated section, and the external heat exchange part 4 adopts a section bar 33 or other different combinations. When the external heat exchange component 4 is arranged outside the first heat exchange tube 21, preferably, the external heat exchange component 4 and the heat exchange component 3 are symmetrical based on the first heat exchange tube 21. When the external heat exchange component 4 is arranged outside the second heat exchange tube 22, preferably, the external heat exchange component 4 and the heat exchange component 3 are symmetrically arranged based on the second heat exchange tube 22. Of course, the external heat exchange component 4 and the heat exchange component 3 may not be symmetrically arranged based on the first heat exchange tube 21 or the second heat exchange tube 22.
In the embodiments, as the heating heat exchanger can use refrigerant (fluorine-containing refrigerant) or water as a heat exchange medium, in order to improve the heat exchange efficiency and improve the heat exchange effect, the invention finds that the spacing between the heat exchange components and the height of the heat exchange components are important factors influencing the heat exchange effect through research, the smaller the spacing between the heat exchange components is, the denser the heat exchange components are, the larger the heat exchange area at the side of the heat exchange components is, and the heat exchange can be correspondingly increased to a certain extent; however, the distance between the heat exchange components is too small, which is not beneficial to the natural convection flow of air and further affects the heat transfer effect, and meanwhile, the distance between the heat exchange components which is too small can also increase the weight of the whole heating sheet, and the cost is increased. Another important influence factor is the height of the heat exchange component, the higher the height of the heat exchange component is, the larger the heat exchange area of the heat exchange component is, and the larger the heat exchange quantity is within a certain range; however, the number of the heat exchange components is increased, and the temperature of the end (close to the air side) of each heat exchange component is lower than that of the root of the substrate, so that the heat transfer temperature difference between the end of each heat exchange component and the air is small, and the heat transfer efficiency is low. Moreover, when the heat exchange members 3 are fins 32, for example, the size of the heat exchange members 3 is changed to increase the difficulty and cost of production, and the size of the heat exchange members 3 is related to the size of the heat exchange channels 31. Therefore, in consideration of the above reasons, the values of the parameters of the heat exchange component 3 obtained through research can be as follows:
the direction that heat exchange component 3 extends from top to bottom is the width direction, the direction that heat exchange component 3 extends from left to right is length direction, the direction that heat exchange component 3 extends from front to back is the direction of height. The width, length and height of the heat exchange channels 31 are in the same direction as the heat exchange members 3. The height of the heat exchange channel 31 can range from 20mm to 200mm, and preferably, the height of the heat exchange channel 31 can range from 40mm to 80 mm; for example 25mm, or 55mm or 60mm etc. (for example, the distance Z of the hollow part 321 of the partition part 32 shown in fig. 3, or the distance Y between two extending parts 332 shown in fig. 4, or the distance Y between two adjacent profiles 33), preferably, the length of the heat exchange channel 31 may be in the range of 20mm to 25 mm; for example, 15mm, or 35mm, or 20mm, etc. In addition, the thickness of the heat exchange member 3 may be in the range of 0.08mm to 5 mm. For example, the thickness of the side wall 321, the top wall 322 and the bottom wall 323 of the fin 32 is 0.08mm to 5 mm; or at least one of the thicknesses of the side wall 321, the top wall 322 and the bottom wall 323 is 0.08mm to 5 mm. For another example, the thickness of the base 331 and the extension 332 of the profile 33 is 0.08mm to 5mm, or the thickness of at least one of the base 331 and the extension 332 is 0.08mm to 5 mm.
FIG. 7 is a schematic diagram of the construction of a first heat exchange tube (or a second heat exchange tube) in an exemplary embodiment; fig. 8 is a schematic diagram of the configuration of a first heat exchange tube (or a second heat exchange tube) coupled to a header in an exemplary embodiment. As shown in fig. 7 and 8, taking the first heat exchange tube 21 as an example, the first heat exchange tube 21 includes a main body segment 25, an end segment 26 connected to the collecting main 1, and a reversing segment 23 connecting the main body segment 25 and the end segment 26. The main section 25 is a main heat exchange part, and the length of the main section is longer than that of the reversing section 23 and the tail section 26. The reversing segment 27 makes a predetermined angle between the end segment 26 and the main segment 25, which may be 90 °, or slightly less than 90 °. For example, when the main body segment 25 is manufactured, a portion of the main body segment 25 may be twisted at a certain angle by twisting to form the end segment 26 and the commutation segment 27.
As can be seen from fig. 7, the larger contact surface (heat transfer surface) of the end segment 26 and the larger contact surface of the main segment 25 are located on two offset planes, the main segment 25 transfers heat with the heat exchange component 3 with a larger contact surface, and the end segment 26 can occupy less axial length of the header 1. Correspondingly, the collecting pipe 1 is provided with a mounting groove 11 for inserting the end section 26, and the length direction of the mounting groove 11 is perpendicular to the axial direction of the collecting pipe 1. Thus, under the same axial length of the collecting pipe 1, more heat exchange pipes 2 can be inserted into the collecting pipe 1. As shown in fig. 8, the mounting grooves 11 are transversely disposed on the collecting pipe 1 and are perpendicular to the axial direction of the collecting pipe 1, and a distance x between two adjacent mounting grooves 11 is greater than a distance x between two mounting grooves 11 vertically disposed on the collecting pipe 1 (that is, the length direction of the mounting grooves is parallel to the axial direction of the collecting pipe, see fig. 1), so that a spacing distance is increased, and a pressure resistance of the collecting pipe 1 is improved (especially, when the heat exchanger of the present application uses a fluorine-containing refrigerant as a heat exchange medium, a pressure resistance against the fluorine-containing refrigerant is stronger).
The application has higher conveying pressure compared with an aqueous medium when the fluorine-containing cold medium is adopted. When using a refrigerant medium containing fluorine, the header 1 needs to withstand a high refrigerant pressure. The traditional flat pipes are arranged along the axial direction of the collecting pipe, so that the distance between the adjacent flat pipes is small, the pressure resistance is low, and the traditional flat pipes are not suitable for using a fluorine-containing refrigerant medium and need to use a new connection mode. The problem is solved by changing the connection mode of the flat pipe and the collecting pipe, so that the pressure resistance of the collecting pipe 1 is improved.
As shown in fig. 1 to 8, the first header 10 has an inlet pipe 6 at an upper portion and an outlet pipe 7 at a lower portion. In other embodiments, the inlet pipe 6 and the outlet pipe 7 may be disposed on different headers 1, even on different sides of the header 1. For example, when the heat exchanger 2 has only one flow path, the inlet pipe 6 and the outlet pipe 7 cannot be located on the same header 1, and need to be located on the first header 10 and the second header 15, respectively. When there are at least two flows, the inlet pipe 6 and the outlet pipe 7 may be on the same collecting pipe 1, or may not be on the same collecting pipe 1, and may be specifically determined according to the requirements, the specific number of flows, and the specific structure, which is not limited in the present application. In the embodiment of the drawings shown in the present application, fig. 1, fig. 2, fig. 5, and fig. 6 are provided with two collecting pipes 1, the right sides of a first heat exchange tube 21 and a second heat exchange tube 22 are connected through a reversing part 24, the first heat exchange tube 21 and the second heat exchange tube 22 are respectively connected with a first collecting pipe 10 and a second collecting pipe 15, an inlet pipe 6 and an outlet pipe 7 are arranged in the first collecting pipe 10, and the inlet pipe 6 is located on the upper part of the outlet pipe 7. In fig. 4, 10, and 11, two ends of the first heat exchange tube 21 and the second heat exchange tube 22 are respectively connected to four collecting pipes 1, which are divided into two first collecting pipes 10 and two second collecting pipes 15, the inlet tube 6 is disposed on the two left collecting pipes 1 (the left first collecting pipe 10 and the left second collecting pipe 15) of the heat exchanger, and the outlet tube 7 is located below the inlet tube 6 and connected to the left first collecting pipe 10 and the left second collecting pipe 15. The heat exchange medium enters the left first collecting pipe 10 and the left second collecting pipe 15 from the inlet pipe 6, the left first collecting pipe 10 enters the right first collecting pipe 10 through the heat exchange pipe, the left second heat exchange pipe 15 enters the right second heat exchange pipe 15 through the heat exchange pipe, and finally flows out of the outlet pipe 7 (the flow direction of the heat exchange medium in the heat exchange pipes is shown by an arrow in fig. 10, and the flow details are combined later). The inlet pipe 6 and the outlet pipe 7 are mostly made of copper pipes, the collecting pipe 1 is mostly made of aluminum alloy, and the inlet pipe 6 and the outlet pipe 7 are directly connected with the collecting pipe 1, so that deformation is easy to occur, the connection strength is insufficient, and the refrigerant collecting device is particularly not suitable for using fluorine-containing refrigerants. Therefore, the adapter 5 is arranged on the collecting pipe 1, and the inlet pipe 6 and the outlet pipe 7 are connected with the collecting pipe 1 through the adapter 5. The adapter 5 and the collecting pipe 1 are made of the same material, so that the adapter 5 and the collecting pipe 1 are easy to weld, and then the adapter 5 is used for wrapping the end parts of the inlet pipe 6 and the outlet pipe 7 to fix the inlet pipe and the outlet pipe. The adaptor 5, as an intermediate piece, bears the acting force of the inlet pipe 6 and the outlet pipe 7, but does not act on the collecting main 1 directly, so that the connection strength between the collecting main 1 and the inlet pipe 6 or the outlet pipe 7 can be increased, as follows.
The adaptor 5 includes a first adaptor portion 51, a second adaptor portion 52, and a third adaptor portion 53. The first transfer part 51 is arranged in the collecting pipe 1 and welded with the collecting pipe 1; one end of the second adapter 52 is connected to the first adapter 51, and the other end is connected to the third adapter 53. The second adapter 52 has an outer diameter larger than that of the first adapter 51, the second adapter 52 can accommodate the end of the inlet tube 6 or the outlet tube 7, and the third adapter 53 has a flared shape. Taking the inlet tube 6 as an example, the end of the inlet tube 6 can be placed in the second adapter 52 through the third adapter 53. And welding the inner wall of the third adapter part 53 and the outer wall of the inlet pipe 6 by adopting brazing furnace equipment, filling solder between the inner wall of the third adapter part 53 and the inlet pipe 6, and sealing the gap between the inlet pipe 6 and the second adapter part 52. Therefore, the end part of the inlet pipe 6 can be better fixed in the adapter 5, the adapter 5 can be well welded with the collecting pipe 1, the inlet pipe 6 is not directly connected with the collecting pipe 1, and the inlet pipe and the collecting pipe cannot deform due to different materials.
As shown in fig. 2, a partition plate 9 is further disposed inside one of the two collecting pipes 1, the first collecting pipe 10 includes a first cavity 12 and a second cavity 13 separated by the partition plate 9, and the first cavity 12 and the second cavity 13 are respectively connected to different heat exchange tubes, so as to form two flows with different flow directions. The inlet tube 6 is connected to the first chamber 12 and the outlet tube 7 is connected to the second chamber 13. The number of the first cavities 12 connected with the heat exchange tubes 2 is larger than the number of the second cavities 13 connected with the heat exchange tubes 2, and the reason for the arrangement is that when the heat exchanger is used as a condenser, the refrigerant of the first flow is gaseous refrigerant, the density is small, the flow rate is high, so in order to reduce resistance, the first flow needs more heat exchange tubes 2 arranged side by side, the refrigerant is changed into liquid after being radiated through the first flow, the density is increased, and compared with the first flow, the number of the flat tubes in the second flow needs to be reduced.
For example, the partition 9 divides the heat exchange tube 2 into a first part of the heat exchange tube 2a and a second part of the heat exchange tube 2 b. And wherein said first chamber 12 is connected to the inlet pipe 6 for circulating a high temperature heat transfer medium from the compressor and then feeding the heat transfer medium to a first portion of the heat exchange tubes 2a connected to the first chamber 12, the first portion of the heat exchange tubes 2a being primarily for heat exchange with air. The second part of the heat exchange tubes 2b are connected with the outlet pipe 7 through the second chamber 13, and the second chamber 13 is used for collecting the heat transfer medium after heat exchange of the second part of the heat exchange tubes 2b, and then outputting the heat transfer medium to the outlet pipe 7, wherein the flow direction of the heat transfer medium is shown by an arrow in fig. 2. Taking the case that 6 heat exchange tubes 2 are inserted into the collecting pipe 1, the partition plate 9 is arranged between the 4 th heat exchange tube 2 and the 5 th heat exchange tube 2 to form two flows (the upper 4 heat exchange tubes constitute a first part of heat exchange tubes 2a as a first heat exchange flow, and the lower 2 heat exchange tubes constitute a second part of heat exchange tubes 2b as a second heat exchange flow). The refrigerant of the heat transfer medium enters the first cavity 12 through the inlet pipe 6, flows to the four first heat exchange pipes 21 of the first part of heat exchange pipes 2a rightwards, flows to the four second heat exchange pipes 22 of the first part of heat exchange pipes 2a through the reversing part 24, and flows to the two second heat exchange pipes 22 of the second part of heat exchange pipes 2b leftwards through the second collecting pipe 15. The refrigerant flows to the four first heat exchange tubes 21 of the second heat exchange tube part 2b through the reversing part 24, and finally flows to the outlet tube 7 through the second cavity 13 of the first collecting pipe 10. When the heat transfer medium adopts the fluorine-containing refrigerant, the refrigerant entering the heat exchange tube 2 is gaseous, so that the density is low, the flow rate is high, and a plurality of flows are needed to reduce the flow rate and the resistance. After the refrigerant dissipates heat, the gaseous refrigerant is gradually changed into a liquid refrigerant, and the density and the flow rate of the liquid refrigerant are high, so that a small flow is required. The number of flow paths can be appropriately reduced in order to increase the heat convection coefficient on the refrigerant side.

In fig. 10, the partition plates 9 are respectively arranged in the two header pipes 1 at the left end, the upper part of the header pipe 1 is used as a first cavity 12 and is connected with the inlet pipe 6 through a three-way joint, and the lower part of the header pipe 1 is used as a second cavity 13 and is connected with the outlet pipe 7 through a three-way joint. Taking the case that 6 heat exchange tubes 2 are inserted into the collecting pipe 1, the partition plate 9 is disposed between the 4 th and 5 th heat exchange tubes 2 to form two flows (the upper 4 first heat exchange tubes 21 and the 4 second heat exchange tubes 22 are the first heat exchange flows, and the lower 2 first heat exchange tubes 21 and the 2 second heat exchange tubes 22 are the second heat exchange flows). The refrigerant enters a first collecting pipe 10 at the left end of the heat exchanger and a first cavity 12 of a second collecting pipe 15 through an inlet pipe 6 through a three-way joint, then flows to 4 first heat exchange pipes 21 and 4 second heat exchange pipes 22 at the upper part rightwards, and the refrigerant is gathered in the first collecting pipe 10 connected with the right end of the first heat exchange pipe 21 and the second collecting pipe 15 connected with the right end of the second heat exchange pipe 22. The refrigerant flows into the first collecting pipe 10 at the left end of the heat exchanger and the second cavity 13 of the second collecting pipe 15 through the first collecting pipe 10 at the right end and the second collecting pipe 15 through the 2 first heat exchange tubes 21 and the 2 second heat exchange tubes 22 at the lower part, and the refrigerant is gathered to the outlet pipe 7 through the tee joint and flows out. This embodiment is similar to the flow embodiment shown in fig. 2, and when this application heat exchanger used as the condenser, the refrigerant of first flow was gaseous refrigerant, and density is little, and the velocity of flow is high, so in order to reduce the resistance, first flow need more heat exchange tubes that set up side by side, and the refrigerant dispels the heat the back through first flow, and gaseous state becomes liquid, and density increases, in order to guarantee heat transfer capacity, relatively first flow, the quantity of the flat pipe number in the second flow needs to be a little less.
