Description

Technical Field

[0001] At least one embodiment of this utility model relates to the field of total heat exchange core technology, and more particularly to a total heat exchange chip and a total heat exchange core. Background Technology

[0002] A typical total heat exchange core's heat exchange structure consists of multiple identical polygonal total heat exchange chips that are alternately stacked and combined. (Refer to...) Figure 1 and Figure 2 As shown, the total heat exchange chip includes a polygonal frame 1 and a total heat exchange membrane 2 disposed on the frame 1. The frame 1 includes a first frame 15 and a second frame 16, which clamp and fix the total heat exchange membrane 2. The first frame 15 has a first air duct rib 31 that separates the air ducts, and the second frame 16 has a second air duct rib 32 that separates the air ducts. The first air duct rib 31 and the second air duct rib 32 are respectively in contact with a portion of the total heat exchange membrane 2. Multiple total heat exchange chips are arranged in a reverse alternating manner, that is, in the order of first frame 15, total heat exchange membrane 2, second frame 16, total heat exchange membrane 2, and first frame 15, to form a total heat exchange core. The first air duct rib 31 forms a first air duct 7, and the second air duct rib 32 forms a second air duct 8. The air flowing through the first air duct 7 and the second air duct 8 undergoes heat exchange through the total heat exchange membrane 2.

[0003] To better hold and fix the total heat exchange membrane, the first and second air duct ribs need to be in close contact with the total heat exchange core. Therefore, the first and second air duct ribs will cover a portion of the heat exchange area of ​​the total heat exchange membrane, resulting in a reduction in heat exchange efficiency.

[0044] The first embodiment of this disclosure will be described below.

[0045] [First Embodiment]

[0046] This embodiment discloses a total heat exchange chip and a total heat exchange core composed thereof.

[0047] Reference Figure 3 As shown, the total heat exchange core includes a first air duct 7 and a second air duct 8. The first air duct 7 and the second air duct 8 are located on opposite sides of the total heat exchange membrane 2. In this embodiment, the first air duct 7 connects to the room, supplying indoor air to the outside for ventilation. The second air duct 8 connects to the outside, supplying outdoor air to the room for ventilation. The indoor air flowing through the first air duct 7 and the outdoor air flowing through the second air duct 8 undergo total heat exchange via the total heat exchange membrane 2.

[0048] The total heat exchange chip is composed of a total heat exchange core.

[0049] Reference Figure 3 , Figure 4 and Figure 5 As shown, the total heat exchange chip includes a frame 1, a total heat exchange membrane 2, and air duct ribs 3.

[0050] Frame 1 forms the outline of the total heat exchange core and is polygonal. In this embodiment, frame 1 is hexagonal; in other embodiments, frame 1 may also be quadrilateral, etc. Frame 1 is an axisymmetric figure.

[0051] The frame 1 includes a vent 11 and a connecting edge 12.

[0052] The frame 1 includes two vents 11 for allowing airflow to enter the frame 1 and exit the frame 1. In this embodiment, the two vents 11 are arranged parallel to each other. In this embodiment, the vents 11 include a first vent 111 and a second vent 112, which are arranged parallel to each other.

[0053] The air duct rib 3 is used to separate the air duct and connect two ventilation openings 11. That is, one end of the air duct rib 3 is connected to one ventilation opening 11, and the other end of the air duct rib 3 is connected to another ventilation opening 11.

[0054] Reference Figure 3 , Figure 4 and Figure 5 As shown, the connecting edge 12 connects to the edge of the vent 11 and includes a first connecting edge 121 and a second connecting edge 122. In this embodiment, the first connecting edge 121 and the second connecting edge 122 are indirectly connected to the edge of the vent 11. In other embodiments, the first connecting edge 121 and the second connecting edge 122 may also be directly connected to the vent 11.

[0055] In this embodiment, the ventilation opening 11 is rectangular and is formed by the frame 1 and the air duct 3. One end of the air duct 3 divides the ventilation opening 11 into multiple small openings, and air enters the first air duct 7 or the second air duct 8 through the small openings.

[0056] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the frame 1 is hexagonal, including a first connecting edge 121, a second connecting edge 122, a third connecting edge 123 connecting the first connecting edge 121 and the first vent 111, and a fourth connecting edge 124 connecting the second connecting edge 122 and the second vent 112.

[0057] Reference Figure 3 , Figure 4 and Figure 5 As shown, frame 1 includes an orthogonal section and an opposing section 6.

[0058] Reference Figure 3 , Figure 4 and Figure 5As shown, one end of the perpendicular section is connected to the vent 11, and is formed by the third connecting edge 123 or the fourth connecting edge 124, the vent 11, and a portion of the duct rib 3. In this embodiment, the perpendicular section includes a first perpendicular section 51 and a second perpendicular section 52. The first perpendicular section 51 is formed by the third connecting edge 123, the first vent 111, and the duct rib 3 near the third connecting edge 123; the second perpendicular section 52 is formed by the fourth connecting edge 124, the second vent 112, and the duct rib 3 near the fourth connecting edge 124. In the first perpendicular section 51, the duct rib 3 is approximately parallel to the third connecting edge 123. "Approximately parallel" means that the duct rib 3 and the third connecting edge 123 do not intersect. In the second perpendicular section 52, the duct rib 3 is approximately parallel to the fourth connecting edge 124. Similarly, "approximately parallel" means that the duct rib 3 and the fourth connecting edge 124 do not intersect.

[0059] Reference Figure 3 , Figure 4 and Figure 5 As shown, the opposing portion 6 is connected to the perpendicular portion; the connection refers to the end of the opposing portion 6 being connected to the perpendicular portion. The first connecting edge 121 and the second connecting edge 122 are located in the opposing portion 6, and the air duct rib 3 located in the opposing portion 6 is arranged parallel to the first connecting edge 121 and the second connecting edge 122. One end of the first connecting edge 121 is connected to the third connecting edge 123, and the other end is connected to one end of the second vent 112. One end of the second connecting edge 122 is connected to the fourth connecting edge 124, and the other end is connected to one end of the first vent 111. Both ends of the air duct rib 3 in the opposing portion 6 are connected to one end of the air duct rib 3 in the perpendicular portion.

[0060] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the first vent 111 is located on the side closer to the second connecting edge 122, and the second vent 112 is located on the side closer to the first connecting edge 121.

[0061] The air duct ribs 3 located in the frame 1 are divided into a first air duct rib 31 connecting the first ventilation opening 111, a second air duct rib 32 connecting the second ventilation opening 112, and a third air duct rib 33 connecting the first air duct rib 31 and the second air duct rib 32. The first air duct rib 31 is located at the first perpendicular intersection 51, the second air duct rib 32 is located at the second perpendicular intersection 52, and the third air duct rib 33 is located at the opposite part 6.

[0062] Reference Figure 3 , Figure 6 and Figure 7 As shown, the air duct rib 3 includes a contact surface 34 and a connecting surface 35.

[0063] The contact surface 34 is used to contact and adhere to the total heat exchange membrane 2. In this embodiment, the width of the end of the contact surface 34 in the cross-section of the air duct 3 in the direction perpendicular to the airflow direction is smaller than the maximum width of the cross-section of the air duct 3. In this embodiment, the contact surface 34 includes a first contact surface 341 and a second contact surface 342. The first contact surface 341 is the side of the air duct 3 facing the frame 1, and the second contact surface 342 is located on the opposite side of the first contact surface 341. The first contact surface 341 and the second contact surface 342 respectively contact the two total heat exchange membranes 2.

[0064] In this embodiment, the connecting surface 35 is a plane. The connecting surface 35 extends obliquely from the contact surface 34 toward the outer periphery of the air duct 3 and toward the side opposite to the contact surface 34. In this embodiment, the air duct 3 includes multiple connecting surfaces 35, specifically four connecting surfaces 35: two first connecting surfaces 351 that contact the first contact surface 341, and two second connecting surfaces 352 that contact the second contact surface 342. In this embodiment, the first connecting surfaces 351 extend obliquely from the first contact surface 341 toward the second contact surface 342 and toward the outer periphery of the air duct 3. The second connecting surfaces 352 extend obliquely from the second contact surface 342 toward the first contact surface 341 and toward the outer periphery of the air duct 3, i.e., the connecting surfaces 35 are oblique planes that bulge out from the contact surface 34 toward the outer periphery of the air duct 3 and toward the side opposite to the contact surface 34. The cross-section of the air duct 3 in this embodiment is an approximately rhomboid hexagon. It is understandable that the connecting surface 35 can also be a reverse inclined plane that extends concavely from the contact surface 34 toward the inner circumference of the air duct rib 3 and toward the opposite side of the contact surface 34.

[0065] In other embodiments, the connecting surfaces 35 of the air duct rib 3 can be one, two, three, or five, and so on. The cross-section of the air duct rib 3 can also be pentagonal, hexagonal, heptagonal, and so on.

[0066] In other embodiments, the connecting surface 35 may also be a curved surface with its center located inside the air duct rib 3 and extending protruding outwards from the outer periphery of the air duct rib 3. That is, the connecting surface 35 extends protruding from the first contact surface 341 towards the outer periphery of the air duct rib 3 and towards the second contact surface 342. It is understood that the connecting surface 35 may also be a reverse curved surface with its center located outside the air duct rib 3 and extending concave inwards from the inner periphery of the air duct rib 3. That is, the connecting surface 35 extends concave inwards from the first contact surface 341 towards the inner periphery of the air duct rib 3 and towards the second contact surface 342. In other words, in other embodiments, the cross-section of the air duct rib 3 may be approximately circular or approximately star-shaped.

[0067] Furthermore, in this embodiment, the area of ​​the contact surface 34 in contact with the total heat exchange membrane 2 is less than or equal to 10% of the area of ​​the total heat exchange membrane 2. That is, the ratio of the total area of ​​the contact surfaces 34 on all the air duct ribs 3 on a total heat exchange chip in contact with a single total heat exchange membrane 2 to the area of ​​the total heat exchange membrane 2 is less than or equal to 10%.

[0068] In this embodiment, refer to Figure 3 As shown, frame 1 is divided into a first frame 15 and a second frame 16.

[0069] Reference Figure 3 As shown, the first frame 15 is provided with air duct ribs 31 forming the first air duct 7, and the second frame 16 is provided with air duct ribs 3 forming the second air duct 8.

[0070] The first frame 15 and the second frame 16 are alternately overlapped, so that the first vent 111 on the first frame 15 and the second vent 112 on the second frame 16 are on the same side, and the second vent 112 on the first frame 15 and the first vent 111 on the second frame 16 are on the same side. In this embodiment, the total heat exchange chip is stacked in the order of first frame 15, total heat exchange membrane 2, second frame 16, total heat exchange membrane 2, and first frame 15 to form a total heat exchange core, so that the first air duct 7 and the second air duct 8 clamp the same total heat exchange membrane 2, and the airflow directions of a portion of the first air duct 7 and the second air duct 8 intersect at the perpendicular part and are parallel at the opposing part 6, so that the airflow in the first air duct 7 and the second air duct 8 exchanges heat through the total heat exchange membrane 2.

[0071] In this embodiment, the first frame 15 and the second frame 16 have the same structure. By placing them in a mirror-reversed manner, the first air duct 7 and the second air duct 8 intersect, thereby realizing the heat exchange between the two airflows and thus the heat exchange between the air in the two spaces.

[0072] In other words, after the first frame 15 is mirrored, the first air duct 7 becomes the second air duct 8 that can connect to the second space. Similarly, after the first frame 15 is mirrored, the second air duct 8 becomes the first air duct 7 that can connect to the first space. That is, the first frame 15 and the second frame 16 are symmetrically arranged about the axis of symmetry of the first air duct 7 or the second air duct 8.

[0073] The specific implementation of this embodiment will be described below.

[0074] In this embodiment, refer to Figure 3As shown, the total heat exchange chip is formed by the alternating overlap of the first frame 15 and the second frame 16. Indoor air enters the air duct 7 through the first vent 111 and is guided to the outside by the air duct ribs 3. Outdoor air enters the air duct 8 through the first vent 111 and is guided to the room by the air duct ribs 3. This allows indoor air and outdoor air to exchange heat through the total heat exchange membrane 2.

[0075] In this embodiment, refer to Figure 3 , Figure 4 and Figure 7 As shown, the first frame 15 and the second frame 16 overlap. The duct ribs 3 of the first air duct 7 located in the opposing portion 6 on the first frame 15 and the duct ribs 3 of the second air duct 8 located in the opposing portion 6 on the second frame 16 at least partially overlap vertically. For ease of explanation, the duct ribs 3 of the first air duct 7 will be referred to as the first zone duct ribs, and the duct ribs 3 of the second air duct 8 will be referred to as the second zone duct ribs. The first zone duct ribs and the second zone duct ribs are vertically overlapped in the opposing portion 6 with the total heat exchange membrane 2 in between. The first contact surface 341 of the first zone duct ribs and the second contact surface 342 of the second zone duct ribs overlap vertically, clamping the total heat exchange membrane 2, thereby fixing the total heat exchange membrane 2 and preventing it from moving.

[0076] Furthermore, the air duct rib 3 is provided with a connecting surface 35. That is, the air duct rib 3 is provided with a first connecting surface 351 that is inclined from the first contact surface 341 to the outer periphery, and a second connecting surface 352 that is inclined from the second contact surface 342 to the outer periphery. Thus, while keeping the maximum width of the air duct rib 3 unchanged, the area of ​​the contact surface 34 is reduced. This reduces the area of ​​the contact surface 34 covering the heat exchange membrane 2 while ensuring that the heat exchange membrane 2 can be clamped and fixed. This increases the area of ​​heat exchange between the airflow on both sides of the heat exchange membrane 2, thereby improving the heat exchange efficiency.

[0077] Furthermore, in this embodiment, the ratio of the total area of ​​the contact surface 34 of the air duct rib 3 in contact with the total heat exchange membrane 2 to the total area of ​​the total heat exchange membrane 2 is less than or equal to 10%.

[0078] This allows for a further improvement in the heat exchange efficiency of the total heat exchange chip.

[0079] [Second Embodiment]

[0080] The second embodiment of this disclosure will be described below, wherein the same structure as the first embodiment will not be repeated.

[0081] In this embodiment, refer to Figure 8 , Figure 9 and Figure 10As shown, the air duct rib 3 also includes a support column 4. The support column 4 is disposed on the air duct rib 3 and extends protruding from the first contact surface 341 toward the second contact surface 342. The support column 4 includes a first surface 43, a second surface 44, and a side surface 45.

[0082] The first surface 43 of the support column 4 faces the frame 1, and the second surface 44 is located on the opposite side of the first surface 43. The side surface 45 connects the first surface 43 and the second surface 44. In this embodiment, the support column 4 is cylindrical. In other embodiments, the support column 4 can also be a columnar structure such as a prism or frustum.

[0083] The height of the support column 4 is equal to the distance between the first contact surface 341 and the second contact surface 342. The distance between the first contact surface 341 and the second contact surface 342 refers to the straight-line distance N between them. In other words, the first surface 43 of the support column 4 is flush with either the first contact surface 341 or the second contact surface 342, and the second surface 44 is also flush with either the first contact surface 341 or the second contact surface 342.

[0084] At the same time, refer to Figure 9 As shown, the width M of the support column 4 is greater than the width W of the contact surface 34. That is, the width of the first surface 43 or the second surface 44 of the support column 4 is greater than the width of the contact surface 34. Thus, in the direction perpendicular to the total heat exchange membrane 2, the support column 4 protrudes from both sides of the air duct rib 3, covering a portion of the total heat exchange membrane 2.

[0085] Furthermore, in this embodiment, the support columns 4 on two adjacent air duct ribs 3 located on the same side of the total heat exchange membrane 2 are staggered. "Same side of the total heat exchange membrane 2" means located on one of the two sides of the total heat exchange membrane 2. For example, when the first frame 15 and the second frame 16 clamp the same total heat exchange membrane 2, the support columns 4 on two adjacent air duct ribs 3 facing the total heat exchange membrane 2 of the first frame 15 or the second frame 16 are staggered. "Staggered" means that the line connecting the support columns 4 on two adjacent air duct ribs 3 is not perpendicular to the air duct rib 3.

[0086] Furthermore, in this embodiment, the support columns 4 on the air duct ribs 3 are symmetrically arranged with the middle air duct rib 3 as the center line. That is, when there are an odd number of air duct ribs 3, the support columns 4 on the air duct ribs 3 on both sides are symmetrically arranged with the middle air duct rib 3 as the center line. When there are an even number of air duct ribs 3, the support columns 4 on the air duct ribs 3 on both sides are symmetrically arranged with the middle air duct as the center line. Specifically, when there are 3 air duct ribs 3, the air duct ribs 3 from one side to the other are the first air duct rib 3, the second air duct rib 3, and the third air duct rib 3. The support columns 4 on the first air duct rib 3 are staggered from the support columns 4 on the adjacent second air duct rib 3. The support columns 4 of the first air duct rib 3 and the third air duct rib 3 are symmetrically arranged with the second air duct rib 3 as the center line. When there are four air duct ribs 3, from one side to the other, they are designated as the first air duct rib 3, the second air duct rib 3, the third air duct rib 3, and the fourth air duct rib 3. The support columns 4 on the first air duct rib 3 and the second air duct rib 3, the second air duct rib 3 and the third air duct rib 3, and the third air duct rib 3 and the fourth air duct rib 3 are staggered, and the support columns 4 on the first air duct rib 3, the second air duct rib 3, the third air duct rib 3, and the fourth air duct rib 3 are symmetrically arranged with the air duct formed between the second air duct rib 3 and the third air duct rib 3 as the center line.

[0087] Furthermore, the distance between two adjacent support columns 4 on the same air duct rib 3 is less than or equal to X, where X is the length of the first connecting edge 121. This prevents the distance between adjacent support columns 4 from becoming too long, thus suppressing the possibility that the air duct rib 3 between two adjacent support columns 4 might not be able to support the space due to excessive distance.

[0088] Furthermore, in this embodiment, referring to Figure 11 , Figure 12 and Figure 13 As shown, the support column 4 also includes a locking protrusion 46 and a locking groove 47.

[0089] Reference Figure 9 , Figure 10 and Figure 11 As shown, the engaging protrusion 46 extends from the second surface 44 of the support column 4 away from the first surface 43, and the engaging groove 47 is recessed from the first surface 43 towards the second surface 44. The engaging protrusion 46 and engaging groove 47 of adjacent frames 1 can engage with each other.

[0090] In this embodiment, the support column 4 includes a first support column 41 and a second support column 42. The first surface 43 of the first support column 41 is disposed on one side of the frame 1, that is, the engaging protrusion 46 of the first support column 41 is disposed on the side facing the frame 1. The first surface 43 of the second support column 42 is disposed on the other side of the frame 1, that is, the engaging protrusion 46 of the second support column 42 is disposed on the other side of the frame 1. Specifically, in this embodiment, the first frame 15 is provided with the first support column 41 and the second support column 42, wherein the first support column 41 and the second support column 42 are symmetrically arranged about the axis of symmetry of the first air duct 7 or the second air duct 8. When the first frame 15 is reversed to form the second frame 16, and the first frame 15 overlaps with the second frame 16, the engaging protrusion 46 of the first support post 41 on the first frame 15 will engage with the engaging groove 47 of the second support post 42 on the second frame 16, and the engaging groove 47 of the second support post 42 on the first frame 15 will engage with the engaging protrusion 46 of the first support post 41 on the second frame 16.

[0091] The specific implementation of this embodiment will be described below.

[0092] In this embodiment, the first frame 15 and the second frame 16 of the total heat exchange chip are alternately overlapped to form a total heat exchange core. When the first frame 15 and the second frame 16 are overlapped, the first contact surface 341 of the air duct rib 3 on the first frame 15 contacts the first contact surface 341 of the air duct rib 3 on the second frame 16. Since the air duct rib 3 is provided with a support column 4, and the height of the support column 4 is the same as the height of the air duct rib 3, when the air duct ribs 3 contact each other, the support column 4 on the same air duct rib 3 will also contact each other. This prevents the air duct ribs 3 on the two frames 1 from being misaligned along the connecting surface 35 due to the small contact surface 34 of the air duct rib 3. In other words, it prevents the air duct ribs 3 on the two frames 1 from contacting each other at the connecting surface 35, which would cause the two frames 1 to misalign and jam, resulting in a reduction or unevenness in the spacing of the total heat exchange membrane 2 between the two frames 1, increasing the airflow pressure loss and reducing the heat exchange efficiency.

[0093] Furthermore, in this embodiment, the support columns 4 on adjacent air duct ribs 3 are staggered. For example, the support ribs on the first air duct rib 3 and the support columns 4 on the second air duct rib 3 are staggered. Therefore, in the same location of the air duct formed between the first air duct rib 3 and the second air duct rib 3, two support columns 4 will not be simultaneously installed. This prevents the air duct area from being reduced, pressure loss from being increased, heat exchange efficiency from decreasing, or noise from being generated due to the support columns 4 on both sides of the air duct simultaneously blocking the same location.

[0094] Furthermore, in this embodiment, the support columns 4 on the air duct rib 3 are symmetrically arranged with the air duct rib 3 or air duct located in the middle as the center line. Thus, the first frame 15 and the second frame 16 can use the same tool. When overlap is required, the first frame 15 can be reversed to form the second frame 16. At this time, since the support columns 4 are symmetrically arranged, even if the first frame 15 is reversed to form the second frame 16, it can still overlap with the support columns 4 on the first frame 15 to support the air duct rib 3.

[0095] Furthermore, when the first frame 15 is reversed to form the second frame 16, and the two frames overlap, the engaging protrusion 46 of the first support post 41 on the first frame 15 will engage with the engaging groove 47 of the second support post 42 on the second frame 16, and the engaging groove 47 of the second support post 42 on the first frame 15 will engage with the engaging protrusion 46 of the first support post 41 on the second frame 16. This further ensures a fixed connection between the first frame 15 and the second frame 16, thereby suppressing problems such as reduced air duct area caused by misalignment of the two frames. Simultaneously, it enables the production of a single mold, reducing production costs.

[0096] [Third Embodiment]

[0097] The third embodiment of this disclosure will be described below, wherein the same structure as the first and second embodiments will not be repeated.

[0098] In this embodiment, refer to Figure 3 , Figure 4 and Figure 14 As shown, the frame 1 also includes protruding ribs 13 and connecting grooves 14.

[0099] The protruding rib 13 protrudes from the connecting edge 12 toward one side of the total heat exchange membrane 2. In this embodiment, the protruding rib 13 includes a first protruding rib 13 and a second protruding rib 13. The first protruding rib 13 is disposed on the first connecting edge 121, facing the side of the total heat exchange membrane 2, and the second protruding rib 13 is disposed on the second connecting edge 122, facing the opposite side of the total heat exchange membrane 2.

[0100] The connecting groove 14 is located on the opposite side of the connecting edge 12 where the protruding rib 13 is located, and is recessed towards the side where the protruding rib 13 is located. In this embodiment, the connecting groove 14 includes a first connecting groove 14 and a second connecting groove 14. The first connecting groove 14 is located on the first connecting edge 121, and the second connecting groove 14 is located on the second connecting edge 122. The first connecting groove 14 and the second connecting groove 14 are located on opposite sides of the connecting edge 12. Specifically, the connecting groove 14 is located on the other side of the protruding rib 13, that is, the projection of the protruding rib 13 overlaps with the connecting groove 14.

[0101] Furthermore, the connecting groove 14 is provided on the edge of the connecting edge 12. That is, one side of the connecting groove 14 is an opening at the edge of the connecting edge 12. In the cross-sectional direction of the air duct rib 3, the connecting groove 14, the protruding rib 13 and the cross-section of the connecting edge 12 form an approximately S-shape.

[0102] Therefore, when the first frame 15 and the second frame 16 overlap and engage, the protruding rib 13 of the first frame 15 engages and is fixed with the connecting groove 14 of the second frame 16. This reduces the amount of material used, thereby lowering production costs.

[0103] [Fourth Embodiment]

[0104] The fourth embodiment of this disclosure will be described below, wherein the same structure as the first and second embodiments will not be repeated.

[0105] In this embodiment, refer to Figure 5 As shown, the distance between the first connecting edge 121 and the second connecting edge 122 on frame 1 is less than the width of the first connecting edge 121 or the second connecting edge 122. Specifically, the width of the first connecting edge 121 or the second connecting edge 122 is B, and the shortest distance between the first connecting edge 121 and the second connecting edge 122 is C, that is, C < B.

[0106] Furthermore, if the ratio of the width of the first connecting edge 121 or the second connecting edge 122 to the distance between the first connecting edge 121 and the second connecting edge 122 is A, then A = B / C, and 1 < A ≤ 1.5.

[0107] Therefore, the opposing section 6 is rectangular in shape, thereby increasing its area while keeping the total width and height of the frame 1 constant. Since the opposing section 6 has high heat exchange efficiency, the overall heat exchange efficiency can be improved, while balancing airflow pressure loss and cost.
