Technical Field
[0001] This utility model relates to the field of refrigeration technology, and in particular to an optimized air duct structure for a third-generation symmetrical evaporator with a single fan. Background Technology
[0002] Evaporation is the physical process of transforming a liquid into a gaseous state. Generally speaking, an evaporator is an object that transforms a liquid substance into a gaseous state. There are numerous evaporators in industry, among which those used in refrigeration systems are one type. The evaporator is a crucial component of the four main parts of a refrigeration system. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. With the surge in heat dissipation demands from high-density electronic devices, the optimization of the evaporator's airflow structure, as a core heat exchange component of air conditioning systems, has become key to improving energy efficiency and stability. Currently, most existing evaporators employ a dual-fan design to ensure basic heat dissipation.
[0003] However, existing symmetrical evaporators rely on dual fans for forced convection and employ relatively simple duct structures. This leads to unstable airflow when the air enters or exits the duct, which can easily cause vortices and result in significant wind noise. To address this issue, a third-generation symmetrical evaporator with a single fan and optimized duct structure is proposed. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides a third-generation symmetrical evaporator single-fan optimized air duct structure, which aims to solve the problem that the existing air duct structure is relatively simple, which leads to unstable airflow when the air enters or exits the air duct, easily causing vortices and resulting in large wind noise.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a third-generation symmetrical evaporator single-fan optimized air duct structure, including an air duct, an air guiding mechanism provided on the inner wall of the air duct, a disassembly mechanism provided on the outer wall of the air duct, and a fan fixedly connected to the inner wall of the air duct. The air guiding mechanism includes a mounting ring frame, a first air guiding grille is fixedly connected to the inner wall of the mounting ring frame, a second air guiding grille is fixedly connected to the right end of the inner wall of the air duct, a diversion ring is fixedly connected to the right end of the air duct, and the right wall of the mounting ring frame is located at the left end of the air duct.
[0006] As a further description of the above technical solution: the inner wall of the diversion ring is fixedly connected with a diversion plate, and the fan is located between the first air guide grille and the second air guide grille.
[0007] As a further description of the above technical solution: a sound-absorbing layer is fixedly connected to the inner wall of the air duct, and an installation plate is fixedly connected to the outer wall of the air duct.
[0008] As a further description of the above technical solution: the disassembly mechanism includes a fixing frame, the outer wall of the fixing frame is fixedly connected to the outer wall of the air duct, and the inner wall of the fixing frame is slidably connected to a positioning column.
[0009] As a further description of the above technical solution: a baffle is fixedly connected to the outer wall of the positioning post, and a spring is sleeved on the outer wall of the positioning post.
[0010] As a further description of the above technical solution: the end of the positioning column is fixedly connected to a pull block, the outer wall of the air duct is provided with a slot, and the right end of the mounting ring is inserted into the inner wall of the slot.
[0011] As a further description of the above technical solution: the outer wall of the mounting ring frame is provided with a positioning hole, and the end of the positioning post is inserted into the inner wall of the positioning hole.
[0012] As a further description of the above technical solution: one end of the spring abuts against the inner wall of the fixing frame, and the other end of the spring abuts against the side wall of the baffle.
[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting air guide grilles at the inlet and outlet of the air duct, air is evenly entered and exited into the air duct to form equal wind pressure, thereby reducing airflow noise. By arranging diverting plates at equal intervals on the inner wall of the diverting ring, the surrounding airflow can be diverted into the air duct. Combined with the second air guide grille, it can further ensure the uniform influx of airflow, avoid eddy currents, and reduce wind noise.
[0014] 2. In this utility model, when it is necessary to disassemble the mounting ring frame, the user can pull the pull block to drive the positioning post out of the positioning hole on the mounting ring frame, so that the mounting ring frame loses the limiting fixation of the positioning post and can be directly removed from the air duct, which facilitates the maintenance of the air duct interior and the replacement of the sound-absorbing layer, thereby ensuring the noise reduction effect.

A second air guiding grille 203 is fixedly connected to the right end of the inner wall of the air duct 1. A diversion ring 204 is fixedly connected to the right end of the air duct 1. The right wall of the mounting ring frame 201 is located at the left end of the air duct 1. By setting the first air guiding grille 202 and the second air guiding grille 203, air can be evenly entered into and exited from the air duct 1 to form equal air pressure, thereby reducing airflow noise.
[0019] Reference Figure 4 - Figure 5A diverter plate 205 is fixedly connected to the inner wall of the diverter ring 204. The diverter plate 205 can divert the surrounding airflow into the air duct 1. The fan 5 is located between the first air guide grille 202 and the second air guide grille 203. The surfaces and inner walls of the first air guide grille 202 and the second air guide grille 203 are coated with sound-absorbing paint, which can further reduce wind noise.
[0020] Reference Figure 1 , Figure 3 The inner wall of the air duct 1 is fixedly connected to a sound-absorbing layer 6, which is made of sound-absorbing material. The sound-absorbing layer 6 can further reduce wind noise and noise generated by the fan 5. The outer wall of the air duct 1 is fixedly connected to an installation plate 4.
[0021] Reference Figure 3 , Figure 6 - Figure 7 The disassembly mechanism 3 includes a fixed frame 301. The outer wall of the fixed frame 301 is fixedly connected to the outer wall of the air duct 1. The inner wall of the fixed frame 301 is slidably connected to a positioning post 302. The outer wall of the positioning post 302 is fixedly connected to a baffle 303. The force generated by the spring 304 can be transmitted to the positioning post 302 through the baffle 303. The outer wall of the positioning post 302 is fitted with a spring 304. The end of the positioning post 302 is fixedly connected to a pull block 305. The pull block 305 makes it easy for the user to pull the positioning post 302 to move. The outer wall of the air duct 1 has a slot 306. The right end of the mounting ring frame 201 is inserted into the inner wall of the slot 306. The slot 306 can limit the position of the mounting ring frame 201.
[0022] The outer wall of the mounting ring frame 201 is provided with a positioning hole 307. The end of the positioning post 302 is inserted into the inner wall of the positioning hole 307.

One end of the spring 304 abuts against the inner wall of the fixing frame 301, and the other end of the spring 304 abuts against the side wall of the baffle 303. The spring 304 is provided to facilitate the positioning post 302 to reset.
[0023] Working principle: By setting air guide grilles at the inlet and outlet of the air duct 1, the airflow is dispersed, so that the air enters and exits the air duct 1 evenly, forming equal air pressure, thereby reducing airflow noise. By setting a diversion ring 204, and using diversion plates 205 evenly spaced on the inner wall of the diversion ring 204, the surrounding airflow can be diverted into the air duct 1. Combined with the second air guide grille 203, it can further ensure the uniform inflow of airflow, avoid turbulence, and reduce wind noise. The sound-absorbing layer 6 set inside the air duct 1 can further reduce wind noise and the noise generated by the fan 5. When it is necessary to disassemble the mounting ring frame 201, the user can pull the pull block 305 to move the positioning post 302 out of the positioning hole 307 on the mounting ring frame 201, so that the mounting ring frame 201 loses the limiting fixation of the positioning post 302 and can be directly removed from the air duct 1, which facilitates the maintenance of the air duct 1 and the replacement of the sound-absorbing layer 6, thereby ensuring the noise reduction effect.
