Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a water-fluorine plate heat exchanger for air conditioning. Background Technology
[0002] Plate heat exchangers contain a series of parallel, stacked corrugated thin metal heat exchange plates. Each plate includes a first inlet zone, a heat exchange zone, and a second inlet zone arranged sequentially from top to bottom along its length. Each inlet zone has two inlets / outlets arranged along the width of the plate for water inlet or outlet. The heat exchange zone is formed by multiple protrusions spaced apart from top to bottom, along with corresponding grooves, creating multiple troughs and crests. Between adjacent heat exchange plates, the troughs and crests contact each other, forming a mesh of contacts. As the fluid flows between the plates, it is constantly disturbed by these contacts, causing continuous changes in flow velocity and direction, creating strong turbulence even at low flow rates, which is beneficial for efficient heat exchange. Existing plate heat exchangers suffer from poor sealing performance between the heat exchange plates, inaccurate positioning, low heat exchange efficiency due to the presence of heat exchange zones, and a short service life. Utility Model Content
[0003] The main purpose of this utility model is to provide a water-fluorine plate heat exchanger for air conditioning that solves problems such as poor sealing performance, inaccurate positioning performance, low heat exchange efficiency in the heat exchange zone, and short service life.
[0004] To solve the above-mentioned technical problems, this utility model discloses a water-fluorine plate heat exchanger for air conditioning, including at least two stacked heat exchange plates. A first, second, third, and fourth water inlet area are respectively provided around the perimeter of each heat exchange plate. Sealing protrusions are arranged around the outer sides of the first, second, third, and fourth water inlet areas. T-shaped positioning strips with evenly spaced intervals are provided outside the sealing protrusions. A blocking gasket is provided around the second and third water inlet areas. A barrier strip is provided inside the second and third water inlet areas, with both sides of the barrier strip connected to the sealing protrusions. A heat exchange zone is provided within the first, second, third, and fourth water inlet areas. The heat exchange zone has a first V-shaped protrusion area and a second V-shaped protrusion area. The first and second V-shaped protrusion areas have evenly spaced V-shaped protrusion segments with an angle of 60°-80°. Hemispherical recesses are provided at the apex and sides of each V-shaped protrusion segment.
[0005] According to one embodiment of the present invention, a flow channel is provided between the first water inlet area, the second water inlet area, the third water inlet area, the fourth water inlet area and the heat exchange area, and the flow channel is composed of multiple reinforcing ribs.
[0006] According to one embodiment of the present invention, the heat exchange plate is a stainless steel substrate.
[0007] According to one embodiment of the present invention, the angles of the V-shaped protrusions in the first V-shaped protrusion area and the second V-shaped protrusion area are inconsistent and they are arranged asymmetrically.
[0008] Compared with the prior art, this application can achieve the following technical effects:
[0009] 1) By sealing the protrusions and positioning strips, misalignment during assembly is prevented, thus improving sealing reliability; by setting blocking gaskets and barrier strips, the seal is further strengthened to prevent water leakage; by setting the first V-shaped protrusion area, the second V-shaped protrusion area, and the hemispherical recess, the heat exchange efficiency is improved.

Detailed Implementation
[0015] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0016] Please refer to Figure 1 , Figure 1This is a front view of an air conditioner water-fluorine plate heat exchanger according to an embodiment of this application. As shown in the figure, an air conditioner water-fluorine plate heat exchanger includes at least two stacked heat exchange plates 10. The heat exchange plates 10 are respectively provided with a first water inlet area 11, a second water inlet area 12, a third water inlet area 13, and a fourth water inlet area 14. Sealing protrusions 20 are provided around the outer sides of the first water inlet area 11, the second water inlet area 12, the third water inlet area 13, and the fourth water inlet area 14. T-shaped positioning strips 21 with even spacing are provided on the outer side of the sealing protrusions 20. The second water inlet area 12 and the third water inlet area 13 are surrounded by blocking gaskets 30. The inner side of the second water inlet area 12 and the third water inlet area 13 is provided with a barrier strip 31. The two sides of the barrier strip 31 are connected to the sealing protrusions 20.
[0017] In this embodiment of the present invention, a first nozzle area 11, a second nozzle area 12, a third nozzle area 13, and a fourth nozzle area 14 are arranged around the heat exchange plate 10. The first nozzle area 11, the second nozzle area 12, the third nozzle area 13, and the fourth nozzle area 14 facilitate the entry and exit of fluid. A sealing protrusion 20 is arranged around the outside of the first nozzle area 11, the second nozzle area 12, the third nozzle area 13, and the fourth nozzle area 14, and T-shaped positioning strips 21 with uniform spacing are provided on the outside of the sealing protrusion 20. The sealing protrusion 20 and the positioning strips 21 can ensure the accurate positioning of the sealing protrusion 20 and prevent misalignment during assembly. Secondly, a blocking gasket 30 is provided around the second gate area 12 and the third gate area 13. A barrier strip 31 is provided on the inner side of the second gate area 12 and the third gate area 13. The two sides of the barrier strip 31 are connected to the sealing protrusion 20. The blocking gasket 30 and the barrier strip 31 enhance the sealing performance of the second gate area 12 and the third gate area 13. The barrier strip 31 also prevents water from accumulating on the outside of the second gate area 12 and the third gate area 13, allowing water to flow more quickly from the first gate area 11 or the fourth gate area 14.
[0018] Furthermore, heat exchange zones 40 are provided within the first nozzle zone 11, the second nozzle zone 12, the third nozzle zone 13, and the fourth nozzle zone 14. Each heat exchange zone 40 has a first V-shaped protrusion zone 50 and a second V-shaped protrusion zone 60. The first V-shaped protrusion zone 50 and the second V-shaped protrusion zone 60 have evenly spaced V-shaped protrusion segments 70 with an angle of 60°-80°. The angle of the V-shaped protrusion segments 70 balances flow resistance and turbulence intensity, optimizing heat transfer efficiency. Furthermore, the apex and sides of the V-shaped protrusion segments 70 are... There is a hemispherical pit 71, which breaks the laminar boundary layer, increases microturbulence, improves the heat transfer coefficient, and inhibits fouling. The first V-shaped protrusion 50 and the second V-shaped protrusion 60 are connected by the hemispherical pit 71. The angles of the V-shaped protrusions 70 of the first V-shaped protrusion 50 and the second V-shaped protrusion 60 are not the same. By setting the angles of the V-shaped protrusions 70 of the first V-shaped protrusion 50 and the second V-shaped protrusion 60, they are arranged asymmetrically, thereby improving the heat exchange efficiency.
[0019] In addition, a flow channel 80 is provided between the first water inlet zone 11, the second water inlet zone 12, the third water inlet zone 13, the fourth water inlet zone 14 and the heat exchange zone 40. The flow channel 80 is composed of multiple reinforcing ribs 81. The flow channel 80 evenly distributes the fluid, avoids local dead zones, and reduces pressure drop.
[0020] Prior to this, the heat exchange plate 10 is made of stainless steel, which has strong corrosion resistance and pressure resistance, making it very suitable for the overall environment of the heat exchanger.
[0021] In summary, the sealing protrusion 20 and positioning strip 21 prevent assembly misalignment and improve sealing reliability; the blocking gasket 30 and barrier strip 31 further strengthen the seal and prevent water leakage; and the first V-shaped protrusion area 50, the second V-shaped protrusion area 60 and the hemispherical recess 71 improve heat exchange efficiency.
