[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figures 3 to 8As shown, an embodiment of the utility model provides a heat exchanger, which includes a cylinder 31, a plurality of first flow guides 21 and a plurality of second flow guides 22. The cylinder 31 has a liquid separation channel 10 and a heat exchange chamber 311 that are interconnected. The liquid separation channel 10 is provided with a fluid inlet 11 and a plurality of liquid separation holes 12, and the plurality of liquid separation holes 12 are spaced apart along the length direction of the liquid separation channel 10, and the plurality of liquid separation holes 12 are evenly distributed. The liquid separation channel 10 has a first side and a second side that are relatively arranged along the width direction, and the liquid separation channel 10 is connected to the heat exchange chamber 311 through the plurality of liquid separation holes 12. The plurality of first flow guides 21 are spaced apart along the length direction of the liquid separation channel 10 on the first side of the liquid separation channel 10, and the plurality of second flow guides 22 are spaced apart along the length direction of the liquid separation channel 10 on the second side of the liquid separation channel 10, and the first flow guides 21 and the second flow guides 22 are alternately distributed along the length direction of the liquid separation channel 10.

[0030] By applying the technical solution of the present application, the fluid enters the liquid separation channel 10 through the fluid inlet 11, flows from the fluid inlet 11 to the two ends of the liquid separation channel 10, and then is discharged into the heat exchange chamber 311 through the liquid separation hole 12. A plurality of first flow guides 21 are provided on the first side of the liquid separation channel 10, and a plurality of second flow guides 22 are provided on the second side of the liquid separation channel 10, and the first flow guides 21 and the second flow guides 22 are alternately distributed along the length direction of the liquid separation channel 10. In this way, the first flow guides 21 and the second flow guides 22 can accelerate the flow speed of the fluid, facilitate the fluid to flow to the two ends of the liquid separation channel 10 through the fluid inlet 11, and make the fluid pass quickly and evenly along the extension direction of the liquid separation channel 10, so that the fluid can be evenly discharged from the liquid separation hole 12, ensure the liquid separation effect of the liquid separation channel 10, avoid the phenomenon of air suction carrying liquid, and then ensure the working efficiency of the heat exchanger.

[0031] The first flow guide 21 and the second flow guide 22 are arranged obliquely in a direction away from the fluid inlet 11. In the longitudinal direction of the liquid separation channel 10, the first flow guide 21 is at least partially an arc-shaped structure, and the center of the arc-shaped structure of the first flow guide 21 is arranged in a direction away from the fluid inlet 11. Alternatively, along the longitudinal direction of the liquid separation channel 10, the second flow guide 22 is at least partially an arc-shaped structure, and the center of the arc-shaped structure of the second flow guide 22 is arranged in a direction away from the fluid inlet 11. In the present application, in the longitudinal direction of the liquid separation channel 10, the first flow guide 21 is at least partially an arc-shaped structure, and the center of the arc-shaped structure of the first flow guide 21 is arranged in a direction away from the fluid inlet 11, and the second flow guide 22 is at least partially an arc-shaped structure, and the center of the arc-shaped structure of the second flow guide 22 is arranged in a direction away from the fluid inlet 11. With such arrangement, when the fluid flows through the first guide member 21 and the second guide member 22 , the first guide member 21 and the second guide member 22 can play a guiding role, thereby reducing the pressure drop, ensuring the smoothness of the fluid flow, and thereby ensuring that the fluid is evenly discharged from the liquid separation hole 12 .

[0032] The fluid flow direction is a first direction.

[0033] like Figure 6 As shown, along the first direction, the angle α between the first flow guide 21 and the side wall of the first side of the liquid separation channel 10 is not less than 90°, or the angle β between the second flow guide 22 and the side wall of the second side of the liquid separation channel 10 is not less than 90°. In the present application, the angle α between the first flow guide 21 and the side wall of the first side of the liquid separation channel 10 is not less than 90°, and the angle β between the second flow guide 22 and the side wall of the second side of the liquid separation channel 10 is not less than 90°. The first flow guide 21 and the second flow guide 22 are plate-like structures. Such an arrangement can reduce the resistance of the first flow guide 21 and the second flow guide 22 to the fluid, facilitating the flow of the fluid.

[0034] Further, the distance between two adjacent first flow guides 21 is set between 300 mm and 500 mm, or the distance between two adjacent second flow guides 22 is set between 300 mm and 500 mm. In the present application, the distance between two adjacent first flow guides 21 is set between 300 mm and 500 mm, and the distance between two adjacent second flow guides 22 is set between 300 mm and 500 mm.

[0035] Among them, when the distance between two adjacent first guide members 21 is less than 300mm, the distance between two adjacent first guide members 21 is too small, which will increase the resistance encountered by the fluid during flow, making it inconvenient for the fluid to flow in the liquid separation channel 10, thereby affecting the liquid separation effect of the liquid separation channel 10. At the same time, the fluid can easily cause damage to the first guide member 21, thereby reducing the service life of the first guide member 21; when the distance between two adjacent first guide members 21 is greater than 500mm, the first guide member 21 has a poor guiding effect on the fluid, thereby affecting the liquid separation effect of the liquid separation channel 10 on the fluid; therefore, the distance between two adjacent first guide members 21 is set between 300mm and 500mm, which is convenient for the fluid to flow in the liquid separation channel 10, and at the same time can ensure the guiding effect of the first guide member 21 on the fluid, thereby ensuring the liquid separation effect of the liquid separation channel 10 on the fluid. Optionally, the distance between two adjacent first flow guides 21 may be set to 300 mm, 400 mm or 500 mm. In the present application, the distance between two adjacent first flow guides 21 is set to 400 mm.

[0036] At the same time, when the distance between two adjacent second guide members 22 is less than 300 mm, the distance between two adjacent second guide members 22 is too small, which will increase the resistance encountered by the fluid during flow, making it inconvenient for the fluid to flow in the liquid separation channel 10, thereby affecting the liquid separation effect of the liquid separation channel 10. At the same time, the fluid can easily cause damage to the second guide member 22, thereby reducing the service life of the second guide member 22; when the distance between two adjacent second guide members 22 is greater than 500 mm, the second guide member 22 has a poor guiding effect on the fluid, thereby affecting the liquid separation effect of the liquid separation channel 10 on the fluid; therefore, the distance between two adjacent second guide members 22 is set between 300 mm and 500 mm, which is convenient for the fluid to flow in the liquid separation channel 10, and can ensure the guiding effect of the second guide member 22 on the fluid, thereby ensuring the liquid separation effect of the liquid separation channel 10 on the fluid. Optionally, the distance between two adjacent second flow guide members 22 may be set to 300 mm, 400 mm or 500 mm. In the present application, the distance between two adjacent second flow guide members 22 is set to 400 mm.

[0037] Further, the first flow guide 21 is close to the middle of any two adjacent second flow guides 22. Specifically, in the present application, the first flow guide 21 between two adjacent second flow guides 22 is located in the middle of the two second flow guides 22, and the second flow guide 22 between two adjacent first flow guides 21 is located in the middle of the two first flow guides 21. Such an arrangement can further improve the uniformity of liquid separation.

[0038] Specifically, a through hole is provided on the first flow guide 21 or the second flow guide 22, or both the first flow guide 21 and the second flow guide 22. Such a configuration can further increase the flow speed of the fluid and avoid blockage of the fluid at the first flow guide 21 and the second flow guide 22.

[0039] Furthermore, the heat exchanger further comprises a cylinder 31, the fluid inlet 11 is arranged on the cylinder 31, and the liquid separation channel 10 is arranged in the cylinder 31. Such arrangement facilitates the arrangement of the liquid separation channel 10, has a simple structure, and is easy to operate.

[0040] Specifically, the fluid inlet 11 is arranged in the middle of the cylinder 31, that is, the fluid inlet 11 is arranged in the middle of the liquid separation channel 10. In this way, the fluid can be evenly distributed in the liquid separation channel 10 after being discharged from the liquid separation hole 12.

[0041] The heat exchanger further includes a first liquid separator plate 32 and a second liquid separator plate 33. A fluid inlet 11 is provided on the cylinder 31. One side of the first liquid separator plate 32 is connected to the cylinder 31, a plurality of first flow guides 21 are provided between the first liquid separator plate 32 and the cylinder 31, and a plurality of liquid separator holes 12 are provided on the first liquid separator plate 32. One side of the second liquid separator plate 33 is connected to the cylinder 31, the other side of the second liquid separator plate 33 is connected to the other side of the first liquid separator plate 32, a plurality of second flow guides 22 are provided between the second liquid separator plate 33 and the cylinder 31, a plurality of liquid separator holes 12 are provided on the second liquid separator plate 33, and a liquid separator channel 10 is formed between the side of the cylinder 31 having the fluid inlet 11 and the first liquid separator plate 32 and the second liquid separator plate 33. With such a configuration, the structure is simple and it is convenient to assemble the heat exchanger. At the same time, the first liquid separation plate 32 and the second liquid separation plate 33 are arranged gradually away from each other in the direction close to the fluid inlet 11, so that when the fluid is discharged from the liquid separation hole 12, it is convenient for the fluid to disperse to both sides of the fluid inlet 11, thereby ensuring the liquid separation effect of the first liquid separation plate 32 and the second liquid separation plate 33.

[0042] In addition, the outer periphery of the first flow guide member 21 is matched with the inner wall of the first liquid separator plate 32 and the cylinder 31, and the outer periphery of the second flow guide member 22 is matched with the inner wall of the second liquid separator plate 33 and the cylinder 31. The first flow guide member 21 can support the first liquid separator plate 32, and the second flow guide member 22 can support the second liquid separator plate 33, thereby reducing the deformation of the first flow guide member 21 and the second flow guide member 22 during the assembly process and further ensuring the uniformity of liquid separation.

[0043] like Figure 8 As shown, there is an angle between the first liquid separation plate 32 and the second liquid separation plate 33 , and the angle γ between the first liquid separation plate 32 and the second liquid separation plate 33 is set between 100° and 130°. When the angle γ between the first liquid separation plate 32 and the second liquid separation plate 33 is less than 100°, the friction and impact between the fluid and the first liquid separation plate 32 and the second liquid separation plate 33 are large, which will increase the pressure drop, making it inconvenient for the fluid to flow, and the fluid is very likely to reflux; when the angle γ between the first liquid separation plate 32 and the second liquid separation plate 33 is greater than 130°, the flow rate of the fluid in the liquid separation channel 10 is low, and it is inconvenient for the fluid to be discharged from the liquid separation hole 12; therefore, the angle γ between the first liquid separation plate 32 and the second liquid separation plate 33 is set between 100° and 130°, which can ensure the smoothness of the fluid circulation and effectively avoid the reflux of the fluid, which is beneficial to the uniform and rapid liquid separation of the first liquid separation plate 32 and the second liquid separation plate 33, and improves the liquid separation efficiency of the first liquid separation plate 32 and the second liquid separation plate 33. The angle between the first liquid separation plate 32 and the second liquid separation plate 33 can be set to 100°, 120° or 130°. In the present application, the angle between the first liquid separation plate 32 and the second liquid separation plate 33 is set to 120°.

[0044] Furthermore, the first liquid separation plate 32 and the second liquid separation plate 33 are symmetrically arranged on both sides of the liquid separation channel 10 with respect to the axis of the fluid inlet 11. Such arrangement facilitates the assembly of the first liquid separation plate 32 and the second liquid separation plate 33, and can ensure the uniformity of liquid separation by the first liquid separation plate 32 and the second liquid separation plate 33. Moreover, in the present application, the first liquid separation plate 32 and the second liquid separation plate 33 have the same structure, are simple in structure, and are easy to assemble.

[0045] Specifically, the cylinder 31 has a chamber, and the first liquid separation plate 32 and the second liquid separation plate 33 cooperate to separate the chamber into a liquid separation channel 10 and a heat exchange chamber 311 .

[0046] The first liquid separation plate 32 and the second liquid separation plate 33 each include a non-porous section and two porous sections, the non-porous section is located between the two porous sections, and the non-porous section is arranged close to the fluid inlet, and a plurality of liquid separation holes are opened in the porous section. Figure 7 As shown, the B area is a non-porous section, and the C area and the D area are perforated sections. In the present application, a fluid outlet is provided on the cylinder 31, the fluid outlet is connected to the heat exchange chamber 311, and the fluid outlet is provided corresponding to the fluid inlet 11. Such a setting can prevent the fluid from entering from the fluid inlet 11 and being discharged directly from the fluid outlet through the liquid separation hole 12, thereby preventing the phenomenon of liquid being carried by air suction, thereby ensuring the liquid separation effect of the first liquid separation plate 32 and the second liquid separation plate 33.

[0047] Furthermore, the first flow guide 21 and the second flow guide 22 are symmetrically arranged on both sides of the liquid separation channel 10 with the fluid inlet 11. Such arrangement can ensure the throttling effect of the first flow guide 21 and the second flow guide 22 on the fluid and improve the fluid circulation speed.
