[0034] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0036] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0037] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped over, an element described as "below" or "beneath" another element or feature would then be oriented "above" or "above" the other element or feature. Thus, the example term "below" can encompass both above and below orientations.

[0038] Commonly used heat exchange devices in related technologies include spiral fin heat exchangers, wire tube heat exchangers, and microchannel condensers. However, the manufacturing process of the above heat exchangers is complex and the production cost is high. Fin heat exchangers can better solve these two shortcomings. Fin heat exchangers are manufactured by first inserting the fins and then bending the tubes. The metal tubes themselves have elastic deformation. Therefore, although the bending after inserting the fins can be fixed, the presence of the heat exchange fins leads to a limited bending angle. Although there are left and right plates to fix the condenser tubes, this production method also results in a large gap between the upper and lower rows of heat exchange fins, which wastes the heat exchange area and leads to low heat exchange efficiency.

[0039] In view of this, this embodiment provides a heat exchange device, which aims to solve the above technical problems by obliquely arranging a connecting portion 30 between two adjacent rows of fins, thereby playing the role of guiding and disturbing flow, improving the heat exchange efficiency and heat exchange effect of the heat exchange device.

[0040] Figures 1 to 6 This is a schematic diagram of the structure of a heat exchange device according to an embodiment of the present invention. In all figures in this specification, the direction substantially parallel to the arrangement of the multiple sub-pipelines 10 is referred to as the first direction X. The direction substantially parallel to the arrangement of the multiple heat exchange fins 2 and intersecting with the first direction X is referred to as the second direction Y. The direction substantially parallel to the arrangement of the first sub-pipeline 100 and the second sub-pipeline 101 is referred to as the third direction Z. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular. In addition, the direction indicated by an arrow in the figures and the direction opposite thereto are considered to be the same direction.

[0041] like Figures 1 to 6 As shown, according to an embodiment of the present invention, a heat exchange device is proposed, which includes a coil 1, a plurality of heat exchange fins 2 and a connector 3. The coil 1 includes a plurality of sub-pipelines 10 arranged at intervals along a first direction X; the plurality of heat exchange fins 2 are connected to the sub-pipelines 10 and arranged at intervals in the sub-pipelines 10, and the plurality of heat exchange fins 2 are arranged in multiple rows, with a heat exchange gap between each two adjacent rows; the connector 3 includes a connecting portion 30, and the connecting portion 30 is provided in at least one heat exchange gap, and the connecting portion 30 is arranged obliquely relative to the axial direction of the sub-pipeline 10.

[0042] The coil 1 and heat exchange fins 2 of this embodiment can be made of metal materials such as aluminum or stainless steel, and the coil 1 and heat exchange fins 2 can be made of the same material. A refrigerant flow channel is provided within the coil 1. The refrigerant in the refrigerant flow channel can be in gaseous or liquid form, or in a gas-liquid two-phase form that evaporates when absorbing heat.

[0043] The structure of the heat exchange fins 2 of this embodiment can be plate-shaped as shown in the figure, and the shape can be rectangular as shown in the figure, or it can be triangular, polygonal or circular, etc., which are not listed one by one in this embodiment.

[0044] The connecting portion 30 of this embodiment is installed in the heat exchange gap between two adjacent rows of heat exchange fins 2. The connecting portion 30 is arranged at an angle relative to the axial direction of the sub-pipeline 10. There is at least one connecting portion 30. A connecting portion 30 can be provided between every two adjacent rows of heat exchange fins 2, or two connecting portions 30 can be provided at intervals. In addition, if the arrangement length of each row of heat exchange fins 2 is long, two or more connecting portions 30 can be provided in each heat exchange gap along the arrangement direction of the heat exchange fins 2 to ensure the heat exchange effect and efficiency of the heat exchange device.

[0045] The heat exchange device of this embodiment can effectively utilize the heat exchange gap between each row of fins by obliquely setting a connecting portion 30 between two adjacent rows of heat exchange fins 2. The connecting portion 30 can play a guiding role, guiding the airflow to blow obliquely upward along the connecting portion 30, thereby increasing the airflow stroke and heat exchange time, and enhancing the heat exchange efficiency and heat exchange effect. At the same time, the connecting portion 30 can also play a disturbing role, forming a negative pressure at the obliquely set connecting portion 30, enhancing the turbulence of the airflow, increasing the turbulence degree, and further improving the heat exchange efficiency and heat exchange effect.

[0046] In some embodiments of the present invention, each row of heat exchange fins 2 includes a plurality of heat exchange fins 2 arranged at intervals along a second direction Y, the second direction Y intersects with the first direction X, and the connecting portion 30 extends along a first inclined direction, which is arranged at an angle to the first direction X.

[0047] The shapes of the multiple sub-pipelines 10 are not limited. For example, the entirety of the sub-pipeline 10 can be approximately straight. Two adjacent sub-pipelines 10 can be connected and communicated through a bend. The multiple sub-pipelines 10 are arranged at intervals along the first direction X, and each row of heat exchange fins 2 is connected to the sub-pipeline 10 at intervals along the second direction Y. The connecting portion 30 extends along the first oblique direction. The shape of the connecting portion 30 is rectangular. Its length direction is the same as the arrangement direction of each row of heat exchange fins 2. The first oblique direction is arranged at an angle to the first direction X. Figure 5 As shown, there is a heat exchange gap between two adjacent rows of heat exchange fins 2. Figure 5 From the perspective of , the cross-sectional shape of this heat exchange gap can be regarded as a rectangular shape. The connecting portion 30 in this embodiment is arranged along the diagonal line of the rectangular heat exchange gap. The upper end surface of the connecting portion 30 contacts the lower surface of the upper row of heat exchange fins 2, and the lower end surface of the connecting portion 30 contacts the upper surface of the lower row of heat exchange fins 2. This can increase the windward area of ​​the connecting portion 30 as much as possible, extend the cooling time of the part of the cooling air passing through the connecting portion 30, and further improve the heat exchange efficiency and heat exchange effect. It can be understood that the lower surface of the upper row of heat exchange fins 2 and the upper surface of the lower row of heat exchange fins 2 are the two opposite surfaces of the two adjacent rows of heat exchange fins 2. When the diameter of the sub-pipeline 10 is large, the radius of its bend will also be relatively large. At this time, the inclination of the connecting portion 30 will also increase, and the width of the connecting portion 30 will also increase, so that the turbulence effect will also be enhanced, thereby improving the heat exchange effect.

[0048] In some embodiments of the present invention, the height difference H between the connecting portion 30 and the surface of one of the two adjacent rows of heat exchange fins 2 is 2 mm ≤ H ≤ 3 mm. In the aforementioned configuration of the connecting portion 30, the height difference H between the end of the connecting portion 30 away from the upper surface of the lower row of heat exchange fins 2 and the upper surface of the lower row of heat exchange fins 2, i.e., the vertical distance difference, is 2 mm to 3 mm (e.g., 2 mm, 2.2 mm, 3 mm, or any value within the range of 2 mm to 3 mm). Correspondingly, the height difference H between the end of the connecting portion 30 away from the lower surface of the upper row of heat exchange fins 2 and the lower surface of the upper row of heat exchange fins 2 is also 2 mm to 3 mm.

[0049] In other embodiments, the connection portion 30 can also be set to be higher on the left and lower on the right, or lower on the left and higher on the right. Through this setting, the cooling time of part of the cooling air can be increased, and the heat exchange efficiency and heat exchange effect can be improved.

[0050] In some embodiments of the present invention, the connector 3 further includes a mounting portion connected to the coil 1 and used to mount the connector 30 to the coil 1. Specifically, there are two mounting portions, namely a first mounting portion 31 and a second mounting portion 32. The first mounting portion 31 and the second mounting portion 32 are respectively connected to the connector 30 at both ends along the length of the connector 30. The first mounting portion 31 and the second mounting portion 32 can be connected to the connector 30 by bending or welding a plate to form an integral connection structure. The first mounting portion 31 and the second mounting portion 32 are both provided with mounting holes 33 for mounting the coil 1. The mounting portions are connected to the coil 1 through the mounting holes 33. The two mounting portions are shaped like right-angled trapezoids and have a hypotenuse. The hypotenuse of the mounting portion is connected to the connector 30. The slope of the connector 30 is related to the slope of the hypotenuse. As the slope of the hypotenuse increases, the overall slope of the connector 30 also increases accordingly, thereby adjusting the slope of the connector 30. The shape of the mounting portion is adapted to the size of the heat exchange fins 2, with the difference being that the shape of the heat exchange fins 2 is rectangular. When installing the connector 3, the mounting portion replaces the first and last fins of each row of heat exchange fins 2 respectively, that is, the first mounting portion 31 is installed to the position of the first fin of each row of heat exchange fins, and the second mounting portion 32 is installed to the position of the last heat exchange fin in the row, so as to install the connector 3 as a whole.

[0051] Of course, the structural forms of the connecting portion 30 and the mounting portion of this embodiment are not limited thereto, and may be, for example, a triangle, a square, or other irregular shapes, etc., which are not listed one by one in this embodiment.

[0052] In addition, the connector 3 can also be installed by welding, plugging, etc., fixed between two adjacent rows of heat exchange fins 2, or integrally formed between two adjacent rows of heat exchange fins 2 by mold injection, etc., and this embodiment does not impose too many restrictions on this.

[0053] In some embodiments of the present invention, the sub-pipeline 10 includes a first sub-pipeline 100, multiple first sub-pipelines 100 are arranged at intervals along a first direction X, and two adjacent first sub-pipelines 100 are connected, the first direction X and the axial direction of the first sub-pipeline 100 are perpendicular to each other, wherein each row of heat exchange fins 2 is connected to the first sub-pipeline 100.

[0054] Each first sub-pipeline 100 is evenly spaced along the first direction X. That is, the spacing between any two adjacent first sub-pipelines 100 along the first direction X is equal. Adjacent first sub-pipelines 100 are connected via the first bend 11. The multiple first sub-pipelines 100 and the multiple first bends 11 form an integrated piping structure that extends in a serpentine shape, saving layout space while increasing the length of the coil 1 and improving heat exchange efficiency and effectiveness. The multiple heat exchange fins 2 in each row of heat exchange fins 2 are evenly spaced along the second direction Y. That is, the spacing between any two adjacent heat exchange fins 2 along the second direction Y is equal. This arrangement ensures uniform heat exchange within the coil 1.

[0055] In some embodiments of the present invention, the sub-pipeline 10 further includes a second sub-pipeline 101, and multiple second sub-pipelines 101 are arranged at intervals along the first direction X, and two adjacent second sub-pipelines 101 are connected. Multiple first sub-pipelines 100 correspond one-to-one to multiple second sub-pipelines 101, and are arranged relatively along the third direction Z. The first direction X and the axial direction of the second sub-pipeline 101 are perpendicular to each other, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other, wherein each row of heat exchange fins 2 is connected to the first sub-pipeline 100 and the second sub-pipeline 101.

[0056] Multiple second sub-pipelines 101 are spaced apart along the third direction Z on either side of the multiple first sub-pipelines 100. Each second sub-pipeline 101 is evenly spaced along the first direction X, i.e., the spacing between any two adjacent second sub-pipelines 101 along the first direction X is equal. Each second sub-pipeline 101 is of the same length and is arranged parallel to each other. Adjacent second sub-pipelines 101 are connected by a second curved portion 12. The multiple second sub-pipelines 101 and the multiple second curved portions 12 form an integrated piping structure that extends in a serpentine shape, saving layout space while increasing the length of the coil 1 and improving heat exchange efficiency and effectiveness. By providing multiple first sub-pipelines 100 and multiple second sub-pipelines 101, the overall length of the coil 1 can be increased, extending the time the refrigerant passes through the coil 1, further improving heat exchange efficiency and effectiveness.

[0057] In other embodiments, only the first sub-pipeline 100 or the second sub-pipeline 101 may be provided according to heat exchange requirements, and the number of sub-pipelines 10 may be increased, which is not limited in this embodiment.

[0058] In this embodiment, the heat exchange device also includes two side plates, namely a first side plate and a second side plate. The first side plate and the second side plate are respectively arranged at both ends of the multiple rows of heat exchange fins 2 along the second direction Y, and the first side plate and the second side plate are arranged along the first direction X. The first side plate and the second side plate are both provided with through holes adapted to the coil 1, and the first side plate and the second side plate are interference fitted to the coil 1 through the through holes.

[0059] During the production of the heat exchange device of this embodiment, the specific size of the fin heat exchange device is planned according to the design of the compressor compartment and the heat exchange requirements; the appropriate size of the coil 1 is selected according to the design size of the heat exchange device, the bending radius of the coil 1 is calculated and determined, the size of the heat exchange fins 2, the number of fins and the interval between fins are determined, and the first and last fins of each row of heat exchange fins 2 are removed based on the original design parameters; the fins are arranged by the fin arrangement machine and the fin arrangement mold, and after each row of heat exchange fins 2 is arranged, the first and last fins 2 of the row of heat exchange fins 2 are removed. Install the mounting part to the position of the first and last heat exchange fins 2 to replace the original heat exchange fins 2; arrange the fins row by row according to the above steps, and install the connector 3; place the U-shaped condenser tube on the groove of the fin arrangement mold, and push the coil 1 through the arranged heat exchange fins 2; connect the head and tail ends of the coil 1, use high-pressure gas or other media to expand the tube to make an interference fit between the heat exchange fins 2 and the coil 1 to fix the heat exchange fins 2; use a tube bending machine to bend the tube according to the design requirements and bending radius; install the first side plate and the second side plate on the coil 1 through interference fit.

[0060] The above-mentioned production method adopts the method of first passing the fins through the U-shaped tube and then bending it for production, which can reduce costs, reduce welding points, and ensure the service life of the heat exchange device. In addition, without changing the original production arranging mold, when the arranging machine is used for arranging, the parameters of the arranging machine are changed, the first and last pieces of each row of heat exchange fins 2 are cancelled, and the connector 3 is placed in this position through the installation part to replace the original heat exchange fins 2. After that, normal tube expansion and bending can be carried out to ensure production efficiency.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
