Description

Technical Field

[0001] This utility model relates to a plastic sensible heat exchange chip for use in stacked heat exchange cores, belonging to the field of ventilation equipment components. Background Technology

[0002] A sensible heat exchange core is a type of heat exchange core in a fresh air exchanger, composed of stacked sensible heat exchange chips. Traditional sensible heat exchange chips are made of paper material, fixed to a frame, and then stacked to form the core. The disadvantages are that paper exchange chips (diaphragms) are easily damaged, have a short lifespan, and are cumbersome to produce and assemble. Therefore, in recent years, some have developed sensible heat exchange chips made of metal materials; however, metal sensible heat exchange chips are expensive, affecting user experience. Therefore, based on market demand, the applicant has designed a low-cost, long-life plastic sensible heat exchange chip. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a plastic sensible heat exchange chip that is integrally injection molded from plastic material, is easy to process, has low cost, long service life, and is conducive to improving heat exchange efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A plastic heat exchange chip includes an exchange chip integrally injection molded from plastic. The exchange chip comprises a chip body and a support plate. The chip body is provided with evenly distributed undulating flow channels. The support plate is triangular and is disposed on the left and right sides of the chip body. Each of the upper and lower surfaces of the support plate is provided with a guide air channel composed of at least two convex ribs, and the upper guide air channel is arranged opposite to the lower guide air channel. The guide air channel on the left side is arranged symmetrically with the guide air channel on the right side. On the two hypotenuses of the triangular support plate on the left and right sides, there are forward folds and reverse folds that are symmetrical left and right and front and back respectively. When stacked, two adjacent exchange chips are rotated 180° and stacked. The forward folds and reverse folds corresponding to the two hypotenuses form flow channel openings. The reverse folds corresponding to the other two hypotenuses are attached to the forward folds and fixedly connected by a connecting structure.

[0006] Furthermore, adjacent convex ribs collide to form a common guiding air duct.

[0007] Furthermore, support protrusions with opposite top and bottom orientations and symmetrical left and right sides are provided on the support plates on both sides, with adjacent support protrusions touching each other.

[0008] Furthermore, the connection structure is an ultrasonic welding connection.

[0009] This invention discloses a plastic heat exchange chip, comprising a chip body and a support plate, both integrally injection molded from plastic material. This reduces cost, lower price, facilitates processing, and extends service life. Specifically, the chip body features evenly distributed undulating flow channels, resembling waves, forming flow channels on both the top and bottom surfaces for ventilation. The support plate employs a triangular structure with forward and reverse folded edges. During stacking, adjacent chips rotate 180°, creating flow channels between the forward and reverse folded edges at two angles, while the reverse folded edges at the other two angles are fixedly connected to the forward folded edges. Multiple chips are stacked to form a robust heat exchange core. Compared to existing paper chips (cores), this significantly improves the overall strength of the heat exchange chip (core), prevents collapse in the middle, extends service life, and increases heat exchange efficiency.

[0013] The present invention will be described in detail below with reference to specific implementation examples. The following implementation examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0014] like Figure 1 — Figure 3As shown, this utility model relates to a plastic sensible heat exchange chip, including an exchange chip 01 integrally injection molded from plastic. The exchange chip 01 consists of a chip body 1 and a support plate 2. The chip body 1 is provided with evenly distributed concave and convex flow channels 7. The support plate 2 is triangular and is provided on the left and right sides of the chip body 1. The upper and lower surfaces of the support plate 2 are each provided with a guide air channel 4 composed of at least two protruding ribs 3, and the upper guide air channel 4 is arranged opposite to the lower guide air channel 4. The left guide air channel 4 is arranged symmetrically with the right guide air channel 4. On the two hypotenuses of the triangular support plate 2 on the left and right sides, there are left-right symmetrical and front-back symmetrical forward folded edges 5 and reverse folded edges 6 respectively. When stacked, two adjacent exchange chips 01 are rotated 180° and stacked. The forward folded edges 5 and reverse folded edges 6 corresponding to the two hypotenuses form a flow channel opening 8. The reverse folded edges 6 corresponding to the other two hypotenuses are attached to the forward folded edges 5 and fixedly connected by a connecting structure. The switching chip 01 described in this solution comprises a chip body 1 and a support plate 2, both integrally injection molded from plastic material, resulting in low cost, low price, easy processing, and long service life. In particular, the chip body 1 features evenly distributed undulating flow channels 7, resembling waves, forming flow channels 7 on both the top and bottom surfaces for ventilation. Simultaneously, the support plate 2 adopts a triangular structure, with forward folded edges 5 and reverse folded edges 6 on the triangular support plate 2. During stacking, two adjacent switching chips 01 rotate 180°, so that the forward folded edges 5 and reverse folded edges 6 corresponding to two of the oblique angles form flow channel openings 8, while the reverse folded edges 6 corresponding to the other two oblique angles are fitted and fixedly connected to the forward folded edges 5. Thus, multiple switching chips 01 are stacked vertically to form a switching core, ensuring a secure stacking.

[0015] Furthermore, the adjacent convex ribs 3 collide to form a common guide air duct, which increases the height of the guide air duct and improves the air intake volume.

[0016] Furthermore, support protrusions 9 are provided on the support plates 2 on both the left and right sides, with opposite top and bottom and symmetrical left and right. The support protrusions 9 that are adjacent to each other collide with each other to improve the support effect.

[0017] Furthermore, the connection structure is an ultrasonic welding connection, which is convenient, reliable, and produces neat edges.

[0018] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
