Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger auxiliary accessories, and in particular to a condensate guide structure for heat exchangers. Background Technology

[0002] In various fields such as industrial production, HVAC, and refrigeration equipment, heat exchangers are the core equipment for heat transfer, and their operating efficiency directly affects the energy consumption and performance of the entire system. The working principle of a heat exchanger is to exchange heat with an external fluid (such as air or water) through heat exchange tubes. To improve heat exchange efficiency, multiple sets of heat exchange fins are usually installed on the outside of the heat exchange tubes to expand the heat exchange contact area and accelerate heat transfer.

[0003] However, during the operation of the heat exchanger, due to the temperature difference between the surface of the heat exchange fins and the external fluid, when the external humid air comes into contact with the low-temperature heat exchange fins, the water vapor in the air will quickly condense and form condensate water that adheres to the surface of the heat exchange fins. The condensate water drips, accumulates, or forms a water film on the surface of the heat exchange fins, which will significantly increase the thermal resistance and reduce the heat exchange rate between the heat exchange fins and the external fluid. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a condensate guiding structure for heat exchangers, which aims to solve the problem in the prior art that "condensate drips, accumulates, or forms a water film on the surface of the heat exchange plates, leading to increased thermal resistance and decreased heat exchange efficiency."

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a condensate guiding structure for a heat exchanger, comprising an outer frame, a connecting pipe fixedly installed on the left side of the outer frame, a heat exchange tube fixedly connected to the inner wall of the outer frame, the connecting pipe being fixedly connected to the end of the heat exchange tube, multiple sets of heat exchange plates fixedly installed on the outer side of the heat exchange tube, a guiding mechanism being provided on the outer side of the heat exchange plates, and a flow guiding mechanism being provided on the rear side of the guiding mechanism;

[0010] The diameters of the left and right sides of the snap-fit ​​component are larger than the diameter of the middle part of the snap-fit ​​component, and the snap-fit ​​component is made of rubber.

[0011] As a further description of the above technical solution:

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a condensate flow guiding structure for a heat exchanger, including an outer frame 1, which provides a stable mounting carrier and fixed support points for components such as connecting pipe 2, heat exchange pipe 3, and collection tank 61. A connecting pipe 2 is fixedly installed on the left side of the outer frame 1, serving as a transmission channel for the heat exchange medium. It is responsible for transporting external heat or cold medium to the inside of the heat exchange pipe 3 and simultaneously exporting the heat-exchanged medium from the device, realizing the circulation of the medium and providing a continuous energy transfer carrier for the heat exchange process. The heat exchange pipe 3 is fixedly connected to the inner wall of the outer frame 1, through which the heat exchange medium flows. It transfers heat to external fluids such as air through the pipe wall and is the main site for heat exchange. The connecting pipe 2 is fixedly connected to the end of the heat exchange pipe 3. Multiple sets of heat exchange plates 4 are fixedly installed on the outer side of the heat exchange pipe 3. By increasing the contact area with the external fluid, the heat transfer between the heat exchange pipe 3 and the external environment is accelerated, heat exchange dead zones are reduced, and the overall heat exchange efficiency is improved. A flow guiding mechanism 5 is provided on the outer side of the heat exchange plate 4, and a flow diversion mechanism 6 is provided on the rear side of the flow guiding mechanism 5.

[0030] Reference Figure 2 - Figure 4The flow guiding mechanism 5 includes a flow guiding groove 51, which is located on the left and right sides of the heat exchange plate 4 and distributed from top to bottom along the outer side of the heat exchange plate 4. This groove quickly collects condensate generated on the surface of the heat exchange plate 4 due to temperature changes, preventing condensate from dripping, spreading, or accumulating randomly on the surface of the heat exchange plate 4. A connecting groove 52 is provided on the lower rear side of the heat exchange plate 4 near the flow guiding groove 51, providing precise positioning for the installation of the flow guiding plate 53. This groove is connected to the mounting groove 54 on the front side of the flow guiding plate 53, ensuring the smooth installation of the flow guiding plate 53. The installation position is accurate and matches the relative position of the guide channel 51, ensuring that the condensate can flow smoothly into the guide plate 53. The guide plate 53 is inserted into the inner wall of the connecting channel 52 to receive the condensate flowing out of the guide channel 51. Through its own structure, it concentrates and guides the dispersed condensate to the guide rod 62 on the rear side, realizing the convergence and diversion of the condensate, ensuring that the condensate flows accurately to the collection tank 61. The heat exchange plate 4 has a horizontally opened mounting hole 55 near the lower part of the connecting channel 52, providing a stable installation space for the snap-fit ​​part 56. The retaining clip 56 can be firmly fixed to the heat exchange plate 4. The inner wall of the mounting hole 55 is provided with the retaining clip 56. The diameter of the left and right sides of the retaining clip 56 is larger than the diameter of the middle part of the retaining clip 56. The retaining clip 56 is made of rubber, which has good elastic deformation ability. Its structural design, with the diameter of the left and right sides being larger than that of the middle part, allows the protruding parts on both sides to be firmly locked in the retaining groove 57 when it is engaged, forming a stable locking effect and preventing the guide plate 53 from loosening. At the same time, the rubber material The elastic properties of the component allow for easy disassembly by applying a certain external force to deform the snap-fit ​​component 56, which can then be easily separated from the slot 57 without the need for complicated tools. This facilitates the cleaning, replacement, or maintenance of the guide plate 53 later. The guide plate 53 has a slot 57 at its lower part, and the snap-fit ​​component 56 engages with the slot 57. The snap-fit ​​component 56 is adapted to the shape of the snap-fit ​​component 56. Through the snap-fit ​​engagement with the snap-fit ​​component 56, the guide plate 53 is firmly fixed in the connecting groove 52, ensuring that the guide plate 53 remains in a stable position during equipment operation.

[0031] Reference Figure 2 - Figure 4 The flow guiding mechanism 5 also includes an installation groove 54, which is located on the front side of the flow guide plate 53 and is inserted into the inner wall of the connecting groove 52. Through this insertion and engagement with the connecting groove 52, the flow guide plate 53 and the heat exchange fins 4 are precisely aligned, ensuring the flow guide plate 53 is securely installed. Baffles 58 are fixedly connected to the upper left and right sides of the flow guide plate 53, forming a barrier that effectively prevents condensate flowing from the flow guide channel 51 into the flow guide plate 53 from spreading and splashing to both sides. The flow guide plate 53, baffles 58, and connecting groove 52 are all arc-shaped. The flow guide channel 51 is inclined, utilizing gravity to accelerate the downward flow of condensate, improving flow guiding efficiency. Furthermore, the lower front part of the flow guide channel 51 is horizontally positioned, increasing its windward surface and thus improving the airflow's ability to blow condensate.

[0032] Reference Figure 2 - Figure 4 The diversion mechanism 6 includes a diversion rod 62, which is fixedly connected to the rear side of the guide plate 53. It receives the condensate collected from the guide plate 53 and guides the condensate precisely into the collection tank 61 below through its own structure. This prevents the condensate from shifting or splashing during its fall and ensures that all the condensate flows into the collection tank 61. The collection tank 61 is fixedly connected to the rear side of the outer frame 1 below the diversion rod 62. It is responsible for receiving the condensate guided down from the diversion rod 62 and realizing the centralized collection of condensate. This prevents the condensate from being directly discharged, which could cause the surrounding environment to be damp or the equipment to be corroded. A drain pipe is fixedly connected to the right side of the collection tank 61. The bottom of the inner wall of the collection tank 61 slopes from left to right.

[0033] Working principle: During heat exchanger operation, the heat exchange medium enters the heat exchange tube 3 through the connecting pipe 2, exchanging heat with the external fluid. The multiple sets of heat exchange fins 4 on the outside of the heat exchange tube 3 increase the heat exchange contact area, allowing for more complete heat exchange. During this process, the external fluid will condense on the surface of the heat exchange fins 4 due to the temperature drop, forming condensate.

[0034] First, the inclined guide grooves 51 distributed from top to bottom along the outer sides of the heat exchange plate 4 quickly collect the condensate on the surface with the help of gravity and guide it to flow downward along the groove. The arc-shaped baffles 58 on the left and right sides of the upper part of the guide plate 53 form a barrier to effectively prevent the condensate from spreading and splashing to both sides, further improving the concentration effect of the condensate.

[0035] Subsequently, the condensate concentrated on the surface of the guide plate 53 flows smoothly along the surface of the arc-shaped guide plate 53 to the guide rod 62 behind it. After the guide rod 62 accurately receives the condensate, it guides it vertically to the collection tank 61 below, preventing the condensate from shifting or scattering during the fall, and ensuring that all the condensate flows into the collection tank 61.

[0036] Finally, the bottom of the inner wall of the collection tank 61 is designed to slope from left to right, which uses gravity to accelerate the flow of condensate to the right and prevent condensate from remaining in the tank. Finally, the collected condensate is quickly discharged from the equipment through the drain pipe on the right side of the collection tank 61, completing the entire process of condensate treatment.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
