Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a fin of a water-to-air intercooler. Background Art

[0002] The water-to-air intercooler uses water as the cooling medium and is mainly used for cooling the boost air of vehicle engines. It is an energy-saving and environmentally friendly product that is beneficial to increasing power and reducing emissions. The fins are the basic heat transfer elements in the intercooler, and their function is to expand the heat exchange area and improve the efficiency of heat transfer.

[0003] However, the existing intercooler fins are usually designed with a continuously bent wavy thin sheet structure, which is likely to deform after being compressed. The deformed intercooler fins will affect the air flow on the surface, affect its heat exchange efficiency, and further affect the performance of the entire air-conditioning system. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a water-to-air intercooler fin, which solves the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A fin of a water-to-air intercooler comprises a fin body and a wavy curved structure of the fin body, wherein the fin body is bent into an integrally formed curved portion and a heat exchange portion, the outer side of the curved portion is stamped with a skeleton beam protruding outward, and the heat exchange portion is stamped with a plurality of skeleton ribs protruding outward, the skeleton ribs are arranged on one side of the heat exchange portion connecting the outer side surface of the curved portion, the skeleton ribs of two adjacent heat exchange portions are staggered, the top of the skeleton rib is arranged as a Y-shaped bifurcated rib, and the Y-shaped bifurcated rib is connected to the skeleton beam.

[0009] Preferably, a support lip plate is arranged opposite to one side of the heat exchange portion located inside the curved portion, and the support lip plates are arranged obliquely, wherein one of the support lip plates abuts against the bottom of the other support lip plate.

[0010] Preferably, the cross-section of the skeleton rib is set to be an ellipse, and the position where the skeleton rib is connected to the heat exchange part is set to be an inwardly concave spoiler groove.

[0011] Preferably, a spacing groove is arranged between two adjacent skeleton ribs on the heat exchange part, and the skeleton ribs on the heat exchange part arranged opposite to each other extend into the spacing groove.

[0012] Preferably, a number of spoiler bulges are vertically arranged on the outer side of the skeleton rib, and the spoiler bulges on the two opposite skeleton ribs are arranged in a staggered manner.

[0013] Preferably, the outer wall of the spoiler protrusion is provided with a vortex guide plate.

[0014] (III) Beneficial effects

[0015] The utility model provides a water-to-air intercooler fin, which has the following beneficial effects:

[0016] 1. In the utility model, the skeleton beams and skeleton ribs stamped and formed at the bending part and the heat exchange part are raised on both sides of the outside of the bending part to form a supporting skeleton. The skeleton ribs lock the outer walls of the bending part and the heat exchange parts connected on both sides on both sides of the skeleton beam to prevent the bending part and the heat exchange parts on both sides from being compressed and deformed. At the same time, the supporting lip plates that interfere with each other are arranged to form support on the inner side of the bending part and the heat exchange part to prevent the inner side of the bending part and the heat exchange part from being compressed and deformed.

[0017] 2. The staggered distribution of the skeleton ribs can guide the airflow through the fin body, so that the airflow passes through the skeleton ribs and enters the spoiler groove between two adjacent skeleton ribs on the opposite heat exchange part through the obstruction of the skeleton ribs, which can improve the heat exchange efficiency between the airflow and the fin body.

[0018] 3. The vortex guide plate on the spoiler convex block can convert the radial airflow into axial airflow. The axial airflow counteracts the airflow that normally passes through the skeleton ribs and the spacing grooves, increasing the disturbance of the airflow, making the air fully contact with the fin body, and improving the heat exchange efficiency.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a water-to-air intercooler fin.

[0026] like Figure 1-3 As shown, it includes a fin body 1, the fin body 1 has a wavy curved structure, the fin body 1 is bent into an integrally formed curved portion 101 and a heat exchange portion 102, the outer side of the curved portion 101 is stamped with a skeleton beam 2 protruding outward, the inner side of the curved portion 101 corresponding to the skeleton beam 2 is stamped as an arched depression, the heat exchange portion 102 is stamped with a plurality of skeleton ribs 3 protruding outward, the position of the heat exchange portion 102 corresponding to the skeleton rib 3 is stamped as an arched depression, the cross-section of the skeleton rib 3 is set to an ellipse, the position where the skeleton rib 3 connects to the heat exchange portion 102 is set to an inwardly concave spoiler groove 4, and the skeleton rib 3 is set at the curved portion where the heat exchange portion 102 connects On one side of the outer side surface of 101, the skeleton ribs 3 of two adjacent heat exchange parts 102 are staggered, the top of the skeleton rib 3 is set as a Y-shaped forked rib 5, the Y-shaped forked rib 5 is connected to the skeleton beam 2, and a triangular support structure is formed between the Y-shaped forked rib 5 and the skeleton beam 2. The heat exchange part 102 is located on the side of the inner side of the bending part 101 and is oppositely provided with a support lip plate 6. The support lip plate 6 is inclined, and one of the support lip plates 6 is in contact with the bottom of the other support lip plate 6. A spacing groove 7 is set between two adjacent skeleton ribs 3 on the heat exchange part 102, and the skeleton ribs 3 on the oppositely arranged heat exchange part 102 extend into the spacing groove 7.

[0027] like Figure 3-4 As shown, a number of spoiler bulges 8 are vertically arranged on the outer side of the skeleton rib 3 , the spoiler bulges 8 on the two oppositely arranged skeleton ribs 3 are arranged alternately, and the outer wall of the spoiler bulge 8 is provided with a vortex guide plate 9 .

[0028] Working principle: In the utility model, the outwardly protruding skeleton beam 2 and skeleton rib 3 stamped out of the curved portion 101 and the heat exchange portion 102 form a stable triangular support structure on both sides of the curved portion 101. The outer portion of the curved portion 101 is tightened by the outwardly protruding arch structure to prevent the outer side of the curved portion 101 from being compressed and deformed. At the same time, the supporting lip plates 6 that conflict with each other are arranged on the inner side of the curved portion 101 to form support on the inner side to prevent the inner side of the curved portion 101 from being deformed.

[0029] In addition, when the external heat exchange air flow rate remains unchanged, the staggered arrangement of the skeleton ribs 3 can enhance the turbulence inside the fin body 1. At the same time, a vortex guide plate is arranged on the outside of the turbulence protrusion 8 to convert the radially blown heat exchange airflow into an axial counter-heat exchange airflow. The counter-heat exchange airflow and the heat exchange airflow flowing along the skeleton ribs 3 and the spacing grooves 7 are counteracted, thereby increasing the airflow turbulence and improving the heat exchange efficiency between the heat exchange airflow and the fin body 1.
