Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to a fresh air device for a condenser of an air-cooled refrigeration unit. Background Technology

[0002] In modern industrial and commercial sectors, air-cooled refrigeration units are widely used in various applications to achieve temperature control in specific spaces. As one of the key components of air-cooled refrigeration units, the performance of the condenser directly affects the efficiency and stability of the entire refrigeration system.

[0003] In existing technologies, the fresh air intake and exhaust systems of traditional condensers are usually located in the same unit. While this design can save space and reduce costs to some extent, it has many drawbacks. First, when the environment is poorly ventilated, the close proximity of the fresh air intake and exhaust systems means that the exhausted hot air can easily be re-inhaled by the fresh air intake before it can fully diffuse. This leads to a so-called "short-circuit circulation" phenomenon, where the hot air just exhausted from the condenser is sent back to the condenser for cooling, greatly reducing the cooling effect. This circulation not only fails to effectively lower the condenser temperature but also keeps the condenser at a high temperature, increasing the energy consumption of the refrigeration unit. Second, when the fresh air intake system installed outdoors encounters rainy weather, the high humidity air contains a large amount of water vapor. When this water vapor is drawn into the fresh air intake system, it enters the condenser and easily condenses into water droplets on the low-temperature surface of the condenser. These water droplets adhere to the condenser's fins, pipes, and other components, affecting heat exchange efficiency. Therefore, there is an urgent need for a fresh air intake system for air-cooled refrigeration unit condensers to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fresh air device for the condenser of an air-cooled refrigeration unit, so as to solve the problem mentioned in the background art that the exhaust air and the absorbed fresh air are intertwined, thus affecting the cooling effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fresh air device for a condenser of an air-cooled refrigeration unit, comprising a main body box, a condenser assembly fixedly connected to the inner wall of the main body box, an exhaust fan fixedly connected to the inner wall of the main body box, a first suction fan fixedly connected to the inner wall of the main body box, and a fresh air supply component provided on the side wall of the main body box.

[0006] The supply component includes a shielding compartment, which is fixedly connected to the side wall of the main body box. A first mounting hole is opened on the surface of the shielding compartment. An air supply shrink tube is fixedly connected to the inner wall of the first mounting hole. An installation box is fixedly connected to the surface of the air supply shrink tube. A second suction fan is fixedly connected to the inner wall of the installation box.

[0007] The installation box has two sliding holes on both sides, and sliding columns are slidably connected to the inner walls of the two sliding holes. Two compression springs are fixedly connected to the side walls of the sliding columns, and a fixing block is fixedly connected to the other end of the compression springs. The side wall of the shielding chamber is fixedly connected to the side wall of the installation box, and bamboo fiber filter cloth is provided on the inner wall of the installation box.

[0008] A drying chamber is fixedly connected to the bottom of the installation box. The bamboo fiber filter cloth is movably sleeved with the surface of the sliding column. Fixing holes are opened on both sides of the drying chamber. The same fixing column is fixedly connected to the inner wall of the two fixing holes. A winding spring is fixedly connected to the surface of the fixing column. One end of the winding spring is fixedly connected to the lower end of the bamboo fiber filter cloth, and the upper end of the bamboo fiber filter cloth is fixedly connected to the inner wall of the installation box.

[0009] A first fixing ring is fixedly connected to the surface of the air supply shrink tube, one end of which is fixedly connected to the surface of the shielding chamber. A second fixing ring is fixedly connected to the surface of the air supply shrink tube, one end of which is fixedly connected to the side wall of the mounting box.

[0010] The main body box has a second mounting hole on its side wall, and a heat dissipation mesh is fixedly connected to the inner wall of the second mounting hole.

[0011] A baffle plate, made of glass, is fixedly connected to the inner wall of the drying chamber.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The design incorporates various components such as a shielding chamber, air supply and contraction pipe, mounting box, sliding hole, fixing block, sliding column, fixing column, winding spring, and shielding plate. These components work together to facilitate the installation of the fresh air intake device in different environments, preventing the fresh air from mixing with the stale air discharged from the main unit and affecting the condensation effect. In rainy weather, the bamboo fiber filter absorbs and filters out moisture from the air. As the weight of the bamboo fiber filter increases, the compression spring contracts, and the winding spring retracts the damp portion of the filter into the drying chamber. When the weather clears, sunlight shines through the shielding plate, drying the damp portion of the bamboo fiber filter inside the drying chamber. Once the filter is dry and lighter, the compression spring extends, returning the filter to its initial position. This ensures that the air absorbed by the main unit remains consistently dry.

A condenser assembly 2 is fixedly connected to the inner wall of the main body box 1. An exhaust fan 3 is fixedly connected to the inner wall of the main body box 1. A first suction fan 4 is fixedly connected to the inner wall of the main body box 1. A fresh air supply component is provided on the side wall of the main body box 1. The supply component includes a shielding chamber 5, which is fixedly connected to the side wall of the main body box 1. A first mounting hole 6 is opened on the surface of the shielding chamber 5. An air supply contraction pipe 7 is fixedly connected to the inner wall of the first mounting hole 6. An installation box 8 is fixedly connected to the surface of the air supply contraction pipe 7. A second suction fan 9 is fixedly connected to the inner wall of the installation box 8.

[0022] Furthermore, two sliding holes 14 are provided on both sides of the installation box 8. Sliding columns 16 are slidably connected to the inner walls of the two sliding holes 14. Two compression springs 17 are fixedly connected to the side walls of the sliding columns 16. A fixing block 15 is fixedly connected to the other end of the compression springs 17. The side wall of the shielding chamber 5 is fixedly connected to the side wall of the installation box 8. The inner wall of the installation box 8 is provided with bamboo fiber filter cloth 18. Through the two sliding holes 14, the sliding columns 16 and the compression springs 17 cooperate with each other to facilitate the sliding columns 16 to slide in the sliding holes 14, thereby driving the bamboo fiber filter cloth 18 to move up and down.

[0023] Furthermore, a drying chamber 12 is fixedly connected to the bottom surface of the mounting box 8. The bamboo fiber filter cloth 18 is movably sleeved with the surface of the sliding column 16. Fixing holes 22 are provided on both sides of the drying chamber 12. The same fixing column 19 is fixedly connected to the inner wall of the two fixing holes 22. A winding spring 20 is fixedly connected to the surface of the fixing column 19. One end of the winding spring 20 is fixedly connected to the lower end of the bamboo fiber filter cloth 18, and the upper end of the bamboo fiber filter cloth 18 is fixedly connected to the inner wall of the mounting box 8. Through the setting of the drying chamber 12, fixing holes 22 and winding spring 20, when the bamboo fiber filter cloth 18 becomes wet and its gravity increases and it moves downward, the winding spring 20 will wind up the bamboo fiber filter cloth 18.

[0024] Furthermore, a first fixing ring 10 is fixedly connected to the surface of the air supply shrink tube 7, one end of which is fixedly connected to the surface of the shielding chamber 5. A second fixing ring 11 is fixedly connected to the surface of the air supply shrink tube 7, one end of which is fixedly connected to the side wall of the mounting box 8. The first fixing ring 10 facilitates the fixing of the air supply shrink tube 7 to the shielding chamber 5, and the second fixing ring 11 facilitates the fixing of the air supply shrink tube 7 to the mounting box 8.

[0025] Furthermore, a second mounting hole 23 is provided on the side wall of the main body box 1, and a heat dissipation mesh 13 is fixedly connected to the inner wall of the second mounting hole 23. The heat dissipation mesh 13 facilitates better heat dissipation for the interior of the main body box 1.

[0026] Furthermore, a baffle plate 21 is fixedly connected to the inner wall of the drying chamber 12. The baffle plate 21 is made of glass. The glass baffle plate 21 facilitates sunlight to reach the bamboo fiber filter cloth 18 inside the drying chamber 12.

[0027] Working principle: Through the installation box 8, when the main body box 1 needs to absorb fresh air, the first suction fan 4 and the second suction fan 9 rotate simultaneously, driving the fresh air to enter the interior of the main body box 1 through the bamboo fiber filter cloth 18 and the air supply contraction pipe 7. This avoids the fresh air from mixing with the old air discharged from the main body box 1, which would affect the condensation effect. When encountering rainy weather outdoors, the bamboo fiber filter cloth 18 absorbs and filters out the moisture carried in the air. When the weight of the bamboo fiber filter cloth 18 increases, the compression spring 17 contracts and the coil spring 20 retracts, bringing the damp part of the bamboo fiber filter cloth 18 back into the drying chamber 12. When the weather clears up, sunlight shines through the baffle plate 21 to dry the damp part of the bamboo fiber filter cloth 18 inside the drying chamber 12. When the bamboo fiber filter cloth 18 is dry and its weight becomes lighter, the compression spring 17 extends, allowing the bamboo fiber filter cloth 18 to return to its initial position. Thus, the main body box 1 keeps the absorbed air in a good dry state, preventing humid air from damaging the internal components of the main body box 1.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
