Description

Technical Field

[0001] This utility model relates to the field of calibrator technology, and in particular to a calibrator. Background Technology

[0002] In a finned heat exchanger, multiple branches of the distributor pipe are connected one-to-one with multiple heat exchange tubes of the finned core. When fluids such as refrigerant enter the heat exchanger, they first reach the main branch of the distributor pipe. Then, according to its internal structure, the fluid is distributed to ensure it flows evenly into each branch pipe, and finally into the multiple heat exchange tubes of the finned core. Inside the heat exchange tubes, the fluid exchanges heat with the air or other media passing through the fins, thus transferring heat.

[0003] As can be seen from the above, the number of branches of the liquid distribution tube is large, for example, some liquid distribution tubes have as many as hundreds of branches. If one or more branches of the liquid distribution tube are deformed during welding, it will be difficult to completely install the liquid distribution tube onto the finned core, which will take a lot of time and greatly affect work efficiency. Summary of the Invention

[0004] This invention provides a corrector to solve the problem that if one or more branches of the existing liquid distribution pipe deform during welding, it will be difficult to completely install the liquid distribution pipe onto the finned core, which will greatly affect the work efficiency.

[0005] A calibrator for calibrating finned dispensing tubes; The fin includes a substrate, on which a plurality of uniformly distributed tube holes are provided; The calibrator includes a calibration template, on which a plurality of uniformly distributed calibration holes are provided; The shape of the calibration template matches the shape of the substrate, and the arrangement of the plurality of calibration holes on the calibration template is the same as the arrangement of the plurality of tube holes on the substrate; the plurality of calibration holes correspond one-to-one with the plurality of tube holes, and the diameters of the two are the same. The distribution tube includes a main tube and multiple branch tubes disposed on the main tube; Multiple branch pipes are simultaneously inserted into multiple calibration holes to calibrate the multiple branch pipes.

[0006] Preferably, each of the correction holes has a guide hole at its insertion end; the diameter of the guide hole gradually decreases along the insertion direction of the branch pipe until it is the same as the diameter of the correction hole.

[0007] Preferably, the guide hole is a tapered guide hole, and the taper of the tapered guide hole is less than or equal to 60°.

[0008] Preferably, the corrector is made of ordinary tool steel.

[0009] Preferably, the plurality of correction holes includes at least one row of correction holes, wherein the correction holes in adjacent rows are arranged in a rectangular or staggered manner.

[0010] Preferably, the correction hole is set to any one of circular, elliptical, and rectangular shapes.

[0011] The calibrator provided in this embodiment is based on fins. After welding a liquid distribution tube that matches a fin of a certain specification, the liquid distribution tube is pushed forcefully so that multiple branches of the liquid distribution tube are simultaneously inserted into multiple calibration holes of the corresponding calibrator. This allows for the calibration of multiple branches. The calibrated liquid distribution tube can then be precisely connected to the multiple heat exchange tubes of the finned core. This greatly improves work efficiency and saves a lot of working time during the installation of the liquid distribution tube. Attached Figure Description

[0018] This utility model embodiment provides a corrector 1, referring to... Figure 1 The calibrator 1 is used to calibrate the liquid distribution tube 2 that matches the fins. The fins include a substrate with a plurality of evenly distributed tube holes. The calibrator 1 includes a calibration template 11 with a plurality of evenly distributed calibration holes 12. The shape of the calibration template 11 matches the shape of the substrate, and the arrangement of the plurality of calibration holes 12 on the calibration template 11 is the same as the arrangement of the plurality of tube holes on the substrate. The plurality of calibration holes 12 correspond one-to-one with the plurality of tube holes, and the diameters of the two are the same. The liquid distribution tube 2 includes a main tube 21 and a plurality of branch tubes 22 disposed on the main tube 21. The plurality of branch tubes 22 are simultaneously inserted into the plurality of calibration holes 12 to calibrate the plurality of branch tubes 22.

[0019] As an example, the fin includes a substrate with a plurality of evenly distributed tube holes. A heat exchange tube is installed in each tube hole. The liquid distribution pipe 2 includes a main pipe 21 and a plurality of branch pipes 22 disposed on the main pipe 21. Each heat exchange tube is connected to one of the branch pipes 22 of the liquid distribution pipe 2. When manufacturing the liquid distribution pipe 2, the plurality of branch pipes 22 are welded to the main pipe 21 in sequence. The workload is large and one or more branch pipes 22 are prone to deformation. Therefore, it is necessary to use a corrector 1 to correct the liquid distribution pipe 2 that matches the fin.

[0020] The calibrator 1 includes a calibration template 11. During design, the shape of the calibration template 11 matches the shape of the substrate. That is, the calibration template 11 is made according to the substrate of the fins, ensuring that the length, width, and thickness of the calibration template 11 are the same as those of the substrate. Multiple uniformly distributed calibration holes 12 are provided on the calibration template 11, and the arrangement of the multiple calibration holes 12 on the calibration template 11 is the same as the arrangement of the multiple tube holes on the substrate. Each of the multiple calibration holes 12 corresponds one-to-one with a multiple tube hole, and both have the same diameter. In other words, the calibration holes 12 on the calibration template 11 are made according to the tube holes on the fin substrate. With this configuration, the calibration holes 12 can replace the tube holes to install a heat exchange tube. When the branch pipe 22 of the liquid distribution pipe 2 can be inserted into the calibration hole 12, it can be ensured that the branch pipe 22 of the liquid distribution pipe 2 can be connected to the heat exchange tube. Therefore, inserting the branch pipe 22 of the liquid distribution pipe 2 into the calibration hole 12 achieves calibration of the branch pipe 22 of the liquid distribution pipe 2 through the calibration holes 12 on the calibration template 11.

[0021] In this example, different specifications of distribution tubes 2 are inserted into the core of the finned mechanism, so each specification of fin is matched with a specific specification of distribution tube 2. The specific process of calibrating the distribution tube 2 is as follows: a calibrator 1 made according to a specific specification of fin is selected. After welding the distribution tube 2 that matches the specification of fin, the distribution tube 2 is pushed forcefully (smaller distribution tubes 2 can be pushed in directly by hand, while larger distribution tubes 2 are pushed in by gently tapping and vibrating with a rubber mallet). This allows multiple branches 22 of the distribution tube 2 to be inserted into multiple calibration holes 12 of the corresponding calibrator 1 simultaneously, thus achieving calibration of multiple branches 22. After calibration, the distribution tube 2 can be precisely connected to the multiple heat exchange tubes of the finned mechanism. This greatly improves work efficiency and saves a lot of working time during the installation of the distribution tube 2. The fins include various specifications, and calibrators 1 of various specifications can be made. The length, width, and thickness of the calibrator 1 are the same as those of the matched fins.

[0022] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 Each calibration hole 12 has a guide hole 13 at its insertion end; the diameter of the guide hole 13 gradually decreases along the insertion direction of the branch pipe 22 until it is the same as the diameter of the calibration hole 12.

[0023] As an example, a guide hole 13 is provided at the insertion end of each calibration hole 12. The guide hole 13 provides precise positioning and guidance for the branch pipe 22 to be inserted into the calibration hole 12, which helps to improve calibration efficiency. The diameter of the guide hole 13 gradually decreases along the insertion direction of the branch pipe 22 until it is the same as the diameter of the calibration hole 12. With this setting, when calibrating the branch pipe 22, the branch pipe 22 is first inserted into the guide hole 13 and then into the calibration hole 12, ensuring that the branch pipe 22 can finally be inserted into the calibration hole 12, thereby realizing the calibration of the branch pipe 22.

[0024] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 The guide hole 13 is a tapered guide hole with a taper of less than or equal to 60°.

[0025] As an example, the guide hole 13 is a tapered guide hole with a taper of less than or equal to 60°. With this setting, the diameter of the tapered guide hole is greater than the deformation of the branch pipe 22. That is to say, in the direction where the branch pipe 22 and the tapered guide hole are connected, the projection of the branch pipe 22 is within the projection of the tapered guide hole. This ensures that each branch pipe 22 can enter its corresponding tapered guide hole, thereby ensuring that the calibrator 1 can calibrate all the branch pipes 22 on the dispensing pipe 2.

[0026] In one embodiment, the corrector 1 is made of ordinary tool steel.

[0027] As an example, the calibrator 1 is made of ordinary tool steel, which has extremely high hardness, excellent wear resistance, heat resistance, toughness, and corrosion resistance, ensuring the service life of the calibrator 1. Ordinary tool steel includes 45 steel and Cr12, etc.

[0028] In one embodiment, reference is made to Figure 2 and Figure 3 The plurality of correction holes 12 include at least one row of correction holes 12, and the correction holes 12 in adjacent rows are rectangularly distributed or staggered.

[0029] As an example, the calibration holes 12 on the calibrator 1 are designed based on the tube holes on the fins. The multiple calibration holes 12 include at least one row of calibration holes 12. The calibration holes 12 in adjacent rows are rectangularly distributed or staggered, which improves the versatility of the calibrator 1.

[0030] In one embodiment, the correction hole 12 is configured as any one of a circle, an ellipse, and a rectangle.

[0031] As an example, the calibration hole 12 can be selected according to the shape of the heat exchange tube, and can be set to any of the circular, elliptical and rectangular shapes to meet the actual use requirements.

[0032] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
