Description

Technical Field

[0001] This utility model relates to the technical field of gas heat exchange equipment, and more specifically, to a vortex flow equalization box and heat exchange equipment. Background Technology

[0002] Currently, a common problem in air conditioning systems is the inconsistency in the pipe diameters of functional modules. This leads to insufficient matching between the delivery pipes and the heat exchanger surface, resulting in uneven fluid distribution and easily causing localized excessively high or low flow velocities. Consequently, this leads to decreased heat exchange efficiency and energy waste. To solve this problem, a porous flow equalization plate is typically added before the heat exchanger. The flow equalization plate's perforated structure redistributes the fluid, thereby improving the uniformity of the flow field.

[0003] However, the design of traditional porous flow equalizers requires adjusting the orifice diameter or number distribution according to the flow field characteristics of different regions. Complex non-uniform orifice arrangements require precise fluid dynamics calculations and simulation verification. The manufacturing process demands high precision in orifice placement and distribution density control, leading to increased production costs and extended production cycles. To ensure sufficient flow equalization, existing solutions often require reserving a large installation space for the flow equalization section, which is particularly disadvantageous in space-constrained applications. Utility Model Content

[0004] The purpose of this utility model is to provide a vortex flow equalization box and heat exchange equipment, which can make the air form a vortex in the box, so that the air distribution at the outlet is uniform, without the need for a large space for diameter change buffer, and the required space size is small.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a vortex flow equalization box, including a box body, an air inlet at one end of the box body, an air outlet at the other end of the box body, and a baffle plate connected to the inner wall of the box body, which divides the space inside the box body into a zigzag flow channel to make the gas form a vortex.

[0007] In an optional embodiment, the baffle plate includes at least one first baffle plate and at least one second baffle plate, and the housing includes a first inner wall and a second inner wall disposed opposite to each other. The first baffle plate is connected to the first inner wall and spaced apart from the second inner wall, and the second baffle plate is connected to the second inner wall and spaced apart from the first inner wall. In the direction from the air inlet to the air outlet, the first baffle plate and the second baffle plate are arranged sequentially at intervals.

[0008] In an optional embodiment, the first baffle is arranged at an angle to the first inner wall, and the second baffle is arranged at an angle to the second inner wall.

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] The following describes in detail the overall structure, working principle, and technical effects of the heat exchange equipment provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0029] Please refer to Figure 1 and Figure 2 The heat exchange device 100 provided by this utility model is applied to air conditioning equipment and is used for heat exchange to regulate air temperature.

[0030] The heat exchange device 100 includes a heat exchanger 20 and a vortex flow equalization box 10. The heat exchanger 20 is used to introduce gas for heat exchange, thereby regulating the air temperature. The vortex flow equalization box 10 is used to provide uniformly distributed air to the heat exchanger 20, improving the heat exchange efficiency of the heat exchanger 20.

[0031] Specifically, the vortex flow equalization box 10 includes a box body 11. An air inlet 12 is provided at one end of the box body 11, and an air outlet 13 is provided at the other end. A baffle plate is connected to the inner wall of the box body 11. The baffle plate divides the space inside the box body 11 into a zigzag flow channel, causing the gas to form a vortex. It can be understood that a gas flow channel is provided inside the box body 11. Air is introduced into the gas flow channel at high speed through the air inlet 12, increasing the cross-section of the flow channel and reducing the air velocity. By setting the baffle plate, the gas flow channel forms a zigzag shape, thereby forming a vortex, further reducing the flow velocity, and evenly dispersing it, resulting in a uniform flow out at the air outlet 13. By setting the baffle plate to form a zigzag gas flow channel, a longer flow equalization section is not required, allowing the size of the vortex flow equalization box 10 to be reduced, making it suitable for installation environments with limited space.

[0032] In this embodiment, the air inlet 12 is used to connect an external fan, allowing high-speed air to enter the housing 11 from the air inlet 12. The air outlet 13 is connected to the air inlet of the heat exchanger 20, so that the air passing through the vortex flow equalization box 10 enters the heat exchanger 20 evenly, thereby improving the heat exchange efficiency of the heat exchanger 20.

[0033] Specifically, the baffle includes at least one first baffle 14 and at least one second baffle 15. The housing 11 includes a first inner wall 111 and a second inner wall 112 disposed opposite to each other. The first baffle 14 is connected to the first inner wall 111 and spaced apart from the second inner wall 112. The second baffle 15 is connected to the second inner wall 112 and spaced apart from the first inner wall 111. In the direction from the air inlet 12 to the air outlet 13, the first baffle 14 and the second baffle 15 are arranged sequentially at intervals.

[0034] In this embodiment, a first baffle 14 and a second baffle 15 are provided, and the first baffle 14 and the second baffle 15 are spaced apart in the direction from the air inlet 12 to the air outlet 13. It can be understood that air is introduced into the housing 11 at high speed from the air inlet 12, guided downwards by the first baffle 14, forming a vortex-like flow after passing over the first baffle 14, and then guided by the second baffle 15 for uniform diffusion, forming a uniformly distributed airflow that is discharged from the air outlet 13.

[0035] Of course, in other embodiments, the first baffle 14 and the second baffle 15 can be configured in other quantities. For example, there can be two first baffles 14 and one second baffle 15. In the direction from the air inlet 12 to the air outlet 13, the first baffle 14, the second baffle 15, and the first baffle 15 are arranged alternately. Alternatively, there can be two first baffles 14 and two second baffles 15. In the direction from the air inlet 12 to the air outlet 13, the first baffle 14, the second baffle 15, and the first baffle 14 and the second baffle 15 are arranged alternately. The first baffle 14 and the second baffle 15 can also be configured in more quantities, with installation positions similar to those in the above embodiments, which will not be repeated here. This utility model does not limit the number of first baffles 14 and second baffles 15.

[0036] To facilitate airflow guidance, the first baffle 14 is set at an angle to the first inner wall 111. The second baffle 15 is set at an angle to the second inner wall 112. Specifically, in this embodiment, both the first baffle 14 and the second baffle 15 are inclined toward the air inlet 12 to block and guide the high-speed air flowing into the air inlet 12.

[0037] Specifically, the angle between the first baffle 14 and the first inner wall 111 is 60°-80°, and the angle between the second baffle 15 and the second inner wall 112 is 60°-80°. In this embodiment, the angle between the first baffle 14 and the first inner wall 111 is 74°, and the angle between the second baffle 15 and the second inner wall 112 is 74°, thereby making the angle between the first baffle 14 and the second baffle 15 32°.

[0038] In this embodiment, the angle between the first baffle plate 14 and the first inner wall 111 is the same as the angle between the second baffle plate 15 and the second inner wall 112, both being 74°. In other embodiments, the angle between the first baffle plate 14 and the first inner wall 111 and the angle between the second baffle plate 15 and the second inner wall 112 can be set differently. The angle between the first baffle plate 14 and the first inner wall 111 and the angle between the second baffle plate 15 and the second inner wall 112 can be set as needed, and this utility model does not limit this.

[0039] It should be noted that in this embodiment, the housing 11 is a square housing 11. The first inner wall 111 is the top surface of the housing 11, and the second inner wall 112 is the bottom surface of the housing 11. The first baffle 14 is connected to the top surface of the housing 11, and the width of the first baffle 14 is the same as the distance between the two sides of the housing 11, so that the first baffle 14 separates the gas flow channels inside the housing 11, thereby allowing the gas to flow only along the first baffle 14 and form a vortex over the first baffle 14. The second baffle 15 is connected to the bottom surface of the housing 11, and the width of the second baffle 15 is the same as the distance between the two sides of the housing 11, so that the second baffle 15 separates the gas flow channels inside the housing 11, thereby allowing the gas to flow only along the second baffle 15 and form a vortex over the second baffle 15, thereby reducing the flow velocity and achieving uniform diffusion.

[0040] Furthermore, the first baffle 14 is rotatably connected to the first inner wall 111, so that the angle between the first baffle 14 and the first inner wall 111 is adjustable. The second baffle 15 is rotatably connected to the second inner wall 112, so that the angle between the second baffle 15 and the second inner wall 112 is adjustable. Specifically, the first baffle 14 can be hinged to the first inner wall 111 via a hinge. The second baffle 15 can be hinged to the second inner wall 112 via a hinge. Of course, in other embodiments, the first baffle 14 and the second baffle 15 can also be rotatably connected to the inner wall of the housing 11 via other structures, such as a rotating shaft connection.

[0041] Furthermore, in order to fix the angle between the first baffle plate 14 and the first inner wall 111, and the angle between the second baffle plate 15 and the second inner wall 112, fasteners are also provided between the first baffle plate 14 and the first inner wall 111, and between the second baffle plate 15 and the second inner wall 112. Specifically, the fasteners can be structures such as pins, to fix the relative positions of the baffle plates and the inner wall of the housing 11.

[0042] Specifically, in this embodiment, the air inlet 12 is located on the side of the housing 11 near the first inner wall 111. It is understood that the first baffle 14 and the second baffle 15 are spaced apart in the direction from the air inlet 12 to the air outlet 13. The end of the first baffle 14 is connected to the first inner wall 111. By positioning the air inlet 12 on the side of the housing 11 near the first inner wall 111, air entering from the air inlet 12 comes into contact with the first baffle 14, allowing the first baffle 14 to guide the air.

[0043] In this embodiment, the housing 11 is a square housing. The housing 11 includes five side walls: a top wall, a left side wall, a front side wall, a rear side wall, and a bottom wall. A first baffle plate 14 is connected to the top wall of the housing 11. A second baffle plate 15 is connected to the bottom wall of the housing 11. The housing 11 does not have a right side wall, thus forming an air outlet 13 on the right side.

[0044] In this embodiment, the air inlet 12 is located at the top of the front side wall of the housing 11. Of course, in other embodiments, the air inlet 12 may be located on the rear side wall or the left side wall of the housing 11, and this utility model does not limit this.

[0045] Furthermore, the air inlet 12 is connected to an air inlet duct 121 via a flange. It is understood that air enters the housing 11 through the air inlet duct 121.

[0046] In this embodiment, the air inlet duct 121 is set at an angle to the side wall of the housing 11. It can be understood that by setting the air inlet duct 121 at an angle to the side wall of the housing 11, air enters the housing 11 at an angle, thereby causing the airflow to collide with the side wall of the housing 11 or the first baffle 14, further reducing the air velocity.

[0047] Furthermore, the air outlet 13 is equipped with a flange connection and a seal. Specifically, the air outlet 13 is connected to the air inlet of the heat exchanger 20 via the flange connection, providing a uniform airflow to the heat exchanger 20. The seal is located between the flange connection and the air inlet of the heat exchanger 20 to prevent air leakage.

[0048] The beneficial effects of the eddy current equalization box 10 and heat exchange device 100 provided in this embodiment of the present invention include:

[0049] The vortex flow equalization box 10 of this invention includes a box body 11. An air inlet 12 is provided at one end of the box body 11, and an air outlet 13 is provided at the other end. A baffle plate is connected to the inner wall of the box body 11. The baffle plate divides the space inside the box body 11 into a zigzag flow channel, causing the gas to form a vortex. Air enters at high speed through the air inlet 12, increasing the flow cross-section and effectively reducing the air velocity. After being deflected and guided by the baffle plate, the air forms a vortex within the box body 11 and then diffuses evenly at the air outlet 13. This invention enables the air to form a vortex within the box body 11, resulting in uniform air distribution at the air outlet 13. It eliminates the need for a large space for diameter-changing buffering, requiring a small space size.

[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
