Description

Technical Field

[0001] The utility model relates to the field of air conditioning heat exchange, in particular to a high-efficiency air conditioning heat exchange module. Background Art

[0002] The evaporator in the air conditioning heat exchange module is one of the key components of the refrigeration system. Its main function is to absorb heat from the indoor air and convert the refrigerant into gas inside the evaporator. The evaporator exchanges heat with the indoor air to reduce the air temperature, thereby making the indoor environment cooler. In this process, the refrigerant absorbs heat and evaporates in the evaporator, and at the same time condenses moisture in the air, reducing humidity and improving air quality.

[0003] Existing air-conditioning evaporators usually include rectangular spirally distributed pipes. Since the fan corresponding to the evaporator uses the rotation of fan blades to assist in heat dissipation, although the rotation of the fan blades can drive the air flow in the entire air-conditioning equipment, the air flow speed is slower at the edge of the rectangle, that is, the air flow speed in the middle of the pipe is fast and the air flow at the edge is slow, which will lead to an uneven overall temperature of the heat sink and the heat dissipation pipe, which not only causes deformation of the pipe, but also easily leads to an increase in energy consumption.

[0004] Therefore, providing a high-efficiency air conditioning heat exchange module has become an issue worthy of study. Utility Model Content

[0032] Specifically, when the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3 are both spiral, the liquid in the spiral first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3 can flow better, and the pipe as a whole has a larger length and surface area, and the heat exchange effect is better;

[0033] When the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 are both distributed in a serpentine shape, see Figure 3 , Figure 4 As shown, the heat exchange efficiency between the pipeline and the surrounding medium is improved, and a longer heat dissipation path can be provided in a limited space, making it more flexible in a small or complex space.

[0034] The inner end openings of the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 are connected by a connecting frame 4 that penetrates the heat-conducting mesh plate 1. The heat-conducting mesh plate 1 is used to form a supporting plate surface for the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3, which acts as a skeleton, improves the structural stability of the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3, can reduce the deformation of the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 under high temperature and vibration of liquid transmission, and can also assist the transfer of heat to ensure that the heat is diffused more effectively.

[0035] The movable ends of the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3 pass through the heat-conducting mesh plate 1, and are respectively provided with a first movable joint 201 and a second movable joint 301 connected to the air-conditioning system. The front and rear surfaces of the heat-conducting mesh plate 1 are detachably connected with a heat dissipation ring frame 5, and the heat dissipation ring frame 5 corresponds to the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3. The heat dissipation ring frame 5 can be used to transfer heat to the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3, and the heat dissipation ring frame 5 is arranged corresponding to the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3, which can more evenly disperse heat and evenly reduce local hot spots. With the rotation of the heat dissipation fan corresponding to the heat dissipation ring frame 5, the heat transfer efficiency is better, thereby greatly improving the heat dissipation performance. In this device, by improving the air flow path and optimizing the design of the radiator pipeline, it is ensured that the air can fully contact the heat exchanger surface, improve the heat exchange efficiency, and thus improve the heat exchange energy efficiency of the air conditioner.

[0036] In a preferred embodiment, the connecting frame 4 is a connecting pipe, and a slot corresponding to the connecting frame 4 is provided on the heat-conducting mesh plate 1, and the slot passes through the outer cylindrical surface of the heat-conducting mesh plate 1, that is, the connecting frame 4 is arranged between the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 by bending, and the connecting frame 4 is close to the middle of the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3. During installation, the connecting frame 4 is passed through the slot, so that the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 are arranged on both sides of the heat-conducting mesh plate 1.

[0037] The second embodiment is different from the first embodiment in that:

[0038] The heat dissipation ring frame 5 includes an inner ring 501 and heat dissipation fins 502 connected to the outer side of the inner ring 501. The heat dissipation fins 502 are in a sheet-like structure and are distributed in a circle with the axis of the inner ring 501 as the reference. The heat dissipation fins distributed in an annular shape can evenly distribute heat, reduce hot spots and cold spots, and improve the overall heat dissipation effect.

[0039] The heat sink fins 502 and the heat conductive mesh plate 1 are made of copper or aluminum, and a graphene layer is provided on their surfaces. Copper and aluminum have good thermal conductivity, and combined with the good thermal conductivity of the graphene layer, the temperature transfer effect is improved; and the heat sink fins 502 are in a zigzag sheet structure, and a mesh is provided on its surface. The folding structure of the zigzag heat sink fins 502 increases the surface area of ​​the heat sink fins 502, and the mesh on the surface of the heat sink fins 502 can not only increase the surface area of ​​the heat sink, but also promote the air flow speed outside the heat sink fins 502, so that heat can be transferred from the heat sink fins 502 to the surrounding environment more quickly, thereby improving the heat dissipation efficiency.

[0040] When the heat dissipation ring frame 5 is installed, the inner wall of the inner ring 501 is provided with a boss, and the boss can be connected to the thermal conductive mesh plate 1 by bolts. The side wall of the heat dissipation fin 502 away from the inner ring 501 is provided with a positioning groove 502a, and the outer side of the thermal conductive mesh plate 1 is detachably connected with a pressure strip 101. The pressure strip 101 has multiple sections, and the inner side thereof is provided with a pressing groove 101a corresponding to the positioning groove 502a, so as to achieve the compression of the heat dissipation fin 502. The outer side of the heat dissipation fin 502 is limited by the insertion of the pressing groove 101a and the positioning groove 502a, and the pressure strip 101 is connected to the thermal conductive mesh plate 1 by bolts, so that the pressure strip 101 can be fixed, the operation is simple and convenient, and the fixing effect is better.

[0041] Furthermore, the connecting frame 4 is a connecting pipe head with a sealing ring, and the middle openings of the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 are both connected to the connecting frame 4. The connecting frame 4 is formed by bending the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3. A boss ring 102 is provided at the axis of the heat conductive mesh plate 1, and the boss ring 102 is plugged and sealed with the connecting frame 4. After the connecting frame 4 is plugged into the boss ring 102, the sealing setting is realized by using the sealing ring, so that the boss ring 102 is plugged and connected to realize the connection between the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3. In the specific structure, the outer side of the movable end of the connecting frame 4 is a conical structure. After the connecting frame 4 is plugged and pressed against the boss ring 102, the first annular heat dissipation tube 2 and the second annular heat dissipation tube 3 can be installed and fixed, and a better sealing effect can be achieved.

[0042] The boss ring 102 is a columnar or frustum-shaped structure with through holes on the surface. The boss on the inner wall of the inner ring 501 is arranged corresponding to the boss ring 102. At this time, the boss and the boss ring 102 can be connected by bolts to fix the inner ring 501.

[0043] In some embodiments, the heat-conducting mesh plate 1 is provided with limiting grooves corresponding to the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3, and the limiting grooves are used to limit the first annular heat dissipation pipe 2 and the second annular heat dissipation pipe 3.

[0044] In a preferred embodiment, the heat dissipation fins 502 are provided with compression grooves 502b corresponding to the first annular heat dissipation tube 2 or the second annular heat dissipation tube 3 on the surface of the heat conduction mesh plate 1. After the heat dissipation fins 502 are installed on the outside of the heat conduction mesh plate 1, the compression grooves 502b can be used to compress the first annular heat dissipation tube 2 or the second annular heat dissipation tube 3. During the use of the device, loosening of the connection position between the connecting frame 4 and the heat conduction mesh plate 1 due to vibration of the device can be avoided.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
