A sealing structure for a plate-fin radiator core

Abstract

This utility model provides a sealing structure for a plate-fin radiator core. The end faces of the outer fins on both sides of the air inlet direction are the air-facing faces. The hot-side channel is arranged perpendicular to the air inlet direction, and long sealing strips are provided on both sides of the hot-side channel in the air inlet direction. The long sealing strips include a protrusion and an embedded part connected sequentially along the air inlet direction. The embedded part is located inside the hot-side channel, and the connecting surface of the embedded part and the protrusion is flush with the air-facing faces. The outer side of the protrusion is inclined towards the adjacent air-facing face. This sealing structure for the plate-fin radiator core, by providing a protrusion at one end of the long sealing strip in the air inlet direction, further defines the inclination direction of the outer side of the protrusion. In use, the outer side of the protrusion can guide the cold-side air blown towards the cold-side end of the long sealing strip along the air inlet direction to the outer fins, preventing the cold-side air from blowing onto the long sealing strip and causing backflow, increasing air inlet resistance and reducing airflow.

Description

Technical Field

[0001] This utility model relates to the field of core sealing technology, and in particular to a sealing strip structure for the core of a plate-fin radiator. Background Technology

[0002] Plate-fin heat exchangers, as a type of highly efficient and compact heat exchange device, typically consist of several layers of alternating hot-side and cold-side channels. These channels are separated by partitions, and fins are arranged within the channels to enhance heat exchange. The cold-side channels are usually arranged along the air inlet direction, with external fins inside to increase the heat exchange area and turbulent the airflow. The hot-side channels, on the other hand, are arranged perpendicular to the air inlet direction. To ensure the channels are airtight and to guide the airflow, long sealing strips are installed on both sides of the hot-side channels along the air inlet direction for sealing.

[0003] See Figure 1-5 The existing plate-fin radiator core includes a side plate A1, a short sealing strip A2, outer fins A3, inner fins A4, a partition plate A5, and a long sealing strip A6. The long sealing strip A6 has a simple rectangular cross-section, and its end face near the air inlet direction is usually a vertical plane perpendicular to the channel. When the cold side air in the environment blows towards the heat exchanger core along the air inlet direction, see... Figure 6 Some airflow will directly impact the vertical end face of the long seal of the hot side channel. This impact will cause loss of airflow energy, increase air intake resistance, and reduce system airflow. In addition, eddies and backflow will be generated near the end face of the long seal, which will disrupt the normal airflow organization to the outer fins of the adjacent cold side channel. This will prevent the airflow from passing through the outer fins smoothly and fully for heat exchange, ultimately leading to a decrease in the overall heat exchange efficiency of the heat exchanger.

[0004] Therefore, in order to solve the above problems, this utility model proposes a sealing structure for the core of a plate-fin radiator that can optimize the end structure of the long sealing strip in the air intake direction, effectively guide airflow, reduce impact loss and improve airflow distribution. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a sealing strip structure for the core of a plate-fin radiator.

[0006] According to one objective of this utility model, this utility model provides a sealing structure for the core of a plate-fin radiator, which has mutually perpendicular air inlet directions and installation directions. The core is provided with alternating hot-side channels and cold-side channels along the installation direction. The cold-side channels are arranged along the air inlet direction, and outer fins are provided inside the cold-side channels. The end faces of the outer fins on both sides of the air inlet direction are the air end faces.

[0007] The hot-side channel is arranged perpendicular to the air inlet direction. Long seals are provided on both sides of the hot-side channel in the air inlet direction. The long seals include a protrusion and an embedded part connected in sequence along the air inlet direction. The embedded part is located inside the hot-side channel. The connecting surface of the embedded part and the protrusion is flush with the air end face. The outer side of the protrusion is inclined towards the adjacent air end face.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The sealing structure of the plate-fin radiator core has a protrusion at one end of the long sealing strip in the air intake direction, which further limits the tilt direction of the outer side of the protrusion. In use, the outer side of the protrusion can guide the cold side air blowing towards the cold side end of the long sealing strip in the air intake direction to the outer fins, avoiding the cold side air blowing onto the long sealing strip and causing backflow, which would increase air intake resistance and reduce air volume.

[0022] The following description is intended to provide a detailed account of the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0023] See Figure 1-6 The existing plate-fin radiator core has a long sealing strip A6 that is suitable for both sides of the inner channel of each layer, which plays the main role of strength support and sealing the antifreeze / oil channel;

[0024] Based on this, see Figure 7-11 This utility model provides a technical solution: a sealing structure for the core of a plate-fin radiator. Generally, the structure includes a hot-side channel a formed by a long sealing strip 6, a partition 5, and an inner fin 4. The outer end face of the long sealing strip 6 and the outer end face of the outer fin 3 form the cold-side windward end of the core. A protrusion is provided at the cold-side windward end of the long sealing strip 6. The protrusion structure plays a role in guiding the cold-side air and strengthening the hot-side channel a.

[0025] Specifically, the sealing structure of the core of the plate-fin radiator is provided with mutually perpendicular air intake direction X and installation direction Y. The core is provided with alternating hot side channels a and cold side channels b along the installation direction Y. The cold side channels b are arranged along the air intake direction X. The cold side channels b are provided with outer fins 3. The end faces of the outer fins 3 on both sides of the air intake direction X are the air end faces.

[0026] The hot-side channel a is arranged perpendicular to the air inlet direction X. Long seals 6 are provided on both sides of the hot-side channel a in the air inlet direction X. The long seals 6 include a protrusion 62 and an embedded part 61 connected in sequence along the air inlet direction X. The embedded part 61 is located inside the hot-side channel a. The connecting surface of the embedded part 61 and the protrusion 62 is flush with the air end face. The outer side of the protrusion 62 is inclined towards the adjacent air end face.

[0027] By providing a protrusion 62 at one end of the long seal 6 in the air inlet direction X, the tilt direction of the outer side of the protrusion 62 is further defined. In use, the outer side of the protrusion 62 can guide the cold side air blowing towards the cold side end of the long seal 6 in the air inlet direction X to the outer fin 3, so as to avoid the cold side air blowing onto the long seal 6 and causing backflow, increasing the air inlet resistance and reducing the air volume.

[0028] Furthermore, the hot-side channel a is provided with the cold-side channel b on both sides in the installation direction Y. That is, the outer side of the protrusion 62 is provided with two adjacent air end faces in the installation direction Y. The outer side of the protrusion 62 is divided into an upper part and a lower part that are continuously arranged in the installation direction Y. The upper part and the lower part are respectively inclined towards the adjacent air end faces.

[0029] Furthermore, the outer surface of the protrusion 62 is arc-shaped. In this embodiment, the outer surface of the protrusion 62 is semi-circular. The arc-shaped protrusion 62 can disperse pressure when under pressure, thereby strengthening the overall strength of the hot side channel a and the core.

[0030] Regarding the specific structure of the core, the core includes:

[0031] Side plates 1 are arranged opposite each other in the installation direction Y. Partition groups are spaced apart between the side plates 1 in the installation direction Y. Each partition group includes two partitions 5 arranged opposite each other in the installation direction Y. Inner fins 4 and long seals 6 are arranged between the partitions 5. The inner fins 4 are located in the middle of the partition 5 in the air inlet direction X, and the long seals 6 are located on both sides of the partition 5 in the air inlet direction X. The partitions 5, inner fins 4, and long seals 6 form the hot-side channel a. Outer fins 3 are arranged between two adjacent partition groups in the installation direction Y. Short seals 2 are arranged on both sides of the outer fins 3 along the length of the hot-side channel a. The cold-side channel b is located between the partitions 5 and the short seals 2.

[0032] Furthermore, both ends of the partition 5 are flush with the adjacent air end face in the air intake direction X to avoid the partition 5 protruding and affecting the airflow between the outer side of the protrusion 62 and the outer fin 3.

[0033] Furthermore, the embedded portion 61 is rectangular, and a triangular protrusion is provided on the side of the embedded portion 61 opposite to the protrusion 62.

[0034] In this embodiment, the partition 5 is a composite plate, and the plate-fin radiator core is an aluminum plate-fin radiator core.

[0035] To further enhance the overall strength of the core, the long seals 6 are symmetrically distributed on both sides of the hot-side channel a located in the air intake direction X.

[0036] In summary, the sealing structure of this plate-fin radiator core changes the traditional planar structure of the long sealing strip A6 at the windward end. The windward end of the long sealing strip 6 is set with an arc-shaped protrusion. Through this method, the cold side air blowing towards the cold side end of the long sealing strip 6 can be guided to the outer fin 3, avoiding the cold side air blowing onto the long sealing strip 6 and causing backflow. Compared with the previous long sealing strip, it not only avoids the problem of cold side air blowing onto the long sealing strip and rebounding, which leads to increased air intake resistance and reduced airflow, but also guides the cold side air to the outer fin to improve air intake efficiency. At the same time, the protrusion in the middle part can also enhance the overall structural strength of the core.

[0037] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
