AI Technical Summary
Existing plate heat exchangers are prone to flow blind spots at the lateral distance away from the angle holes of the circulation plate, which reduces heat exchange efficiency and has weak ability to deal with variable working conditions. They usually can only adapt to a single heat exchange working condition.
A plate heat exchanger with a rotating combination is designed. By setting a heat exchange unit on the plate, the heat exchange unit includes two different corrugated units, which enhances the uniformity of the fluid distribution and reduces the flow dead corners. By adding the plate combination form, the heat exchanger can adapt to more working conditions.
By optimizing the combined form and corrugated design of the plate, the flow blind spots are reduced, the heat exchange efficiency is improved, and the adaptability range of the heat exchanger is expanded, which can meet more working conditions.

[0043] Example 1
[0044] like Figure 1-Figure 5As shown, a plate heat exchanger 1 that can be turned over and rotated is disclosed in the utility model, comprising two heat exchange frames 2 and a plate bundle 3, wherein the two heat exchange frames 2 are respectively a first frame 21 and a second frame 22, a guide rod 23 is installed on the mounting surface of the first frame 21, and a guide groove 24 adapted to the guide rod 23 is provided on the second frame 22, the first frame 21 and the second frame 22 are fixed by a screw assembly, and the gap between the first frame 21 and the second frame 22 is used to install the plate bundle 3;
[0045] The plate bundle 3 includes at least one plate, and a plurality of plates are arranged in sequence and spliced to form a heat exchange area 5. A heat exchange unit 6 is arranged on each plate, and the heat exchange unit 6 includes two corrugated units 7 that equally divide the plate.
[0046] In this embodiment, the plate bundle 3 serves as a heat exchange component and includes a heat exchange plate.
[0047] The two heat exchange frames 2 are installed through guide rods 23 and guide grooves 24. The guide rods 23 on the first frame 21 pass through the guide grooves 24 on the second frame 22. Two guide rods and two guide grooves 24 are provided, which are arranged at upper and lower positions of the first frame 21 and the second frame 22.
[0048] A plurality of limiting grooves are provided on the circumferential sides of the first frame 21 and the second frame 22. The limiting grooves between the first frame 21 and the second frame 22 are fixed by a screw assembly. The screw of the screw assembly passes through the limiting grooves of the first frame 21 and the second frame 22, and then nuts are tightened at both ends of the screw to clamp the first frame 21 and the second frame 22.
[0049] The plate bundle 3 is arranged between the first frame 21 and the second frame 22, and the plate bundle 3 is limited left and right, and the upper and lower ends of the plate bundle 3 are provided with plug holes corresponding to the guide rods, and the guide rods can pass through the plug holes to limit the plate bundle 3 up and down, and fix the plate bundle 3 between the first frame 21 and the second frame 22;
[0050] Medium circulation holes are arranged at the four corners of the plate bundle 3 , and medium inlets are arranged at corresponding positions of the first frame 21 to communicate with the medium circulation holes.
[0051] Each plate bundle 3 is composed of a heat exchange plate, and each heat exchange plate includes at least one plate. When the heat exchange plate has multiple plates, the multiple plates are sequentially spliced and connected together to form a heat exchange area 5. The multiple plates can also be arranged in one piece.
[0052] Each plate has a heat exchange unit 6, and each heat exchange zone 5 is composed of at least one heat exchange unit 6; each heat exchange unit 6 includes two corrugated units 7;
[0053] The two corrugated units 7 of each heat exchange zone 5 evenly divide the surface of the plate.
[0054] Furthermore, the two corrugated units 7 of the plate heat exchange area 5 are symmetrical corrugated units 7, and the two corrugated units 7 are axially symmetrically arranged on the plate.
[0055] Two corrugated units 7 are axially symmetrically arranged on the plate to form a heat exchange unit 6 .
[0056] Furthermore, if Figure 4 and Figure 5 As shown, each of the corrugated units 7 includes corrugations in two directions, and the two corrugated areas are equal in size and symmetrically arranged.
[0057] The two corrugated units 7 of the heat exchange unit 6 are symmetrical, and the two groups of corrugations of each corrugated unit 7 have different directions but are symmetrically arranged.
[0058] The corrugations in two directions are respectively the first corrugation 8 and the second corrugation 9;
[0059] Among them, the angle between the first corrugation 8 and the horizontal direction is β1, the angle between the second corrugation 9 and the horizontal direction is β2, βi=180°-(β1+β2), βi>90° is the first plate 10, and βi<90° is the second plate 11.
[0060] In the above formula, βi refers to the corrugation angle of the plate, β1 refers to the angle between one of the corrugations of the plate and the horizontal plane (the first corrugation 8 in this embodiment), and β2 refers to the angle between another corrugation of the plate and the horizontal plane (the second corrugation 9 in this embodiment).
[0061] According to different heat exchange conditions, select plates with different corrugation angles.
[0062] Example 2
[0063] like Figure 1 , Figure 9-10 As shown, the difference between this embodiment and embodiment 1 is that the two corrugated units 7 of the plate are asymmetric (non-axisymmetric) corrugated units 7, and the two corrugated units 7 are symmetrically arranged about the center of the midpoint of the boundary line of the two corrugated units 7.
[0064] Each corrugated unit 7 includes corrugations in two directions.
[0065] The corrugations in two directions are respectively the first corrugation 8 and the second corrugation 9;
[0066] Among them, the angle between the first corrugation 8 and the horizontal direction is β1, the angle between the second corrugation 9 and the horizontal direction is β2, βi=180°-(β1+β2), βi>90° is the first plate 10, and βi<90° is the second plate 11.
[0067] According to different working conditions of the heat exchanger 1 , the plates of the asymmetric corrugated unit 7 can be selected.
[0068] Example 3
[0069] like Figure 1 , Figure 6-Figure 8 , Figure 11-Figure 16 As shown, further, the plate bundle 3 is composed of heat exchange areas 5 of two heat exchange plates spliced together.
[0070] When the plate bundle 3 is two heat exchange plates, the two plates are two first plates 10 , two second plates 11 , or one first plate 10 and one second plate 11 .
[0071] The plate bundle 3 formed by various combinations of heat exchange plates is installed on the heat exchange frame 2 according to different working conditions.
[0072] For example, Figure 6-Figure 8 It is a symmetrical corrugated heat exchange plate structure;
[0073] Figure 6 In the figure, two second plates 11 are arranged in parallel in the same state (vertically arranged and the corrugation directions can overlap by translation), and then one of the second plates is rotated 180 degrees (on the vertical plane) along its center point, and the corrugations of the two second plates 11 are combined to form a new heat exchange plate. The figure shows a schematic diagram of the corrugation contact of the two second plates 11; in fact, the corrugations on one side of the heat exchange area 5 of the two second plates 11 are fitted together, and the same applies below.
[0074] Figure 7 In the figure, two first plates 10 are arranged in parallel in the same state (vertically arranged and the corrugation directions can overlap by translation), and then one of the first plates is rotated 180 degrees (on the vertical plane) along its center point, and the corrugations of the two first plates 11 are combined to form a new heat exchange plate. The figure shows a schematic diagram of the corrugation contacts of the two first plates 11.
[0075] Figure 8 In the figure, a first plate 10 and a second plate 11 are arranged in parallel in the same state (vertically arranged and the corrugation directions can overlap by translation), and then the first plate 10 / the second plate 11 are rotated 180 degrees (in the vertical plane) along their center points, and the corrugations of the first plate 10 and the second plate 11 are combined to form a new heat exchange plate. The figure shows a schematic diagram of the corrugation contact of the first plate 10 and the second plate 11.
[0076] For example, Figure 11-Figure 16 Asymmetric corrugated heat exchange plate structure
[0077] Fig.11 The two second plates 11 are butt-jointed up and down, and then one of them is turned over along the butt-jointed side to form a new heat exchange plate.
[0078] As shown in 12, two second plates 11 are butt-jointed up and down, and then one of them is flipped along the butt-jointed side, and then one of them is rotated 180° around the center point of the second plate 11, and the rotation axis of the rotated second plate 11 is perpendicular to the contact surface of the other second plate 11, so as to form a new heat exchange plate.
[0079] Fig.13 In the process, two first plates 10 are butt-jointed up and down, and then one of them is turned over along the butt-jointed side to form a new heat exchange plate.
[0080] Fig.14 In the process, two first plates 10 are butt-jointed up and down, and then one of them is flipped along the butt-jointed side, and then one of them is rotated 180° around the center point of the first plate 10, and the rotation axis of the rotated first plate 10 is perpendicular to the contact surface of the other first plate 10, so as to form a new heat exchange plate.
[0081] Fig.15 In the process, a first plate 10 and a second plate 11 are butted up and down, and then the first plate 10 / the second plate 11 are turned over along the butted edge, and the first plate 10 and the second plate 11 are combined to form a new heat exchange plate.
[0082] Fig.16 In the process, a first plate 10 and a second plate 11 are butted up and down, and then the first plate 10 / the second plate 11 are flipped along the butted edge, and then one of them is rotated 180° around the center point, and the first plate 10 and the second plate 11 are combined to form a new heat exchange plate.
[0083] The plates of heat exchanger 1 are asymmetric corrugations, and the plate combination can be a plate flip combination and a plate flipped 180° combination, and the combination type can be increased to 6 types, so that the detachable plate heat exchanger can meet more working conditions.
[0084] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0085] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
[0086] The above is a relatively specific and detailed description of the utility model through general description and specific embodiments. It should be pointed out that, without departing from the concept of the utility model, it is obvious that several variations and improvements can be made to these specific embodiments, which all belong to the protection scope of this application.
