Description
Technical Field
[0001] This utility model belongs to the field of evaporator technology, and in particular relates to a vertical multi-effect evaporator. Background Technology

[0003] Traditional evaporators used in air conditioning systems face a series of severe challenges when working in conjunction with condensers. In terms of evaporation efficiency, the internal structure design of ordinary evaporators is suboptimal. Their heating structure makes it difficult to heat and evaporate the liquid refrigerant evenly and rapidly. Specifically, the layout of the heating tubes is unreasonable, failing to fully utilize the internal space of the evaporator. This results in insufficient heating of the liquid refrigerant in some areas, leading to slow evaporation. This not only significantly prolongs the refrigeration cycle but also greatly reduces the refrigeration efficiency of the air conditioner. Secondly, excessive concentration of refrigerant during the liquid refrigerant introduction stage severely affects the overall evaporation effect, thereby reducing the stability of refrigeration performance.
[0004] In summary, existing evaporators used in conjunction with condensers in air conditioning refrigeration systems have significant defects in terms of heating structure and liquid refrigerant introduction. To address these issues, industry professionals have designed a vertical multi-effect evaporator to effectively overcome these problems, improve evaporation efficiency, optimize the refrigeration cycle, and ensure that the air conditioning system can operate stably and efficiently to meet the ever-increasing refrigeration demand.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.
[0024] Embodiment one:
[0025] In combination with Figs. 1-3The vertical multi-effect evaporator shown, the overall architecture is built around the support frame 1, support frame 1 is made of high-strength alloy steel, with excellent stability and bearing capacity, can in complex working environment, for the whole evaporator system to provide solid and reliable foundation support, in the support frame 1 inside, evaporator body 2 by high-precision installation process is firmly fixed in, evaporator body 2 adopts high-quality corrosion-resistant metal material, the whole is regular vertical cylindrical shape, its internal cavity space after strict fluid dynamics calculation design, aims to realize high efficiency and stable liquid evaporation operation, evaporator body 2 outside wall cover with insulation cotton, into the cavity of evaporator body 2, can see several groups of support rod 3 with precise equidistant ring array way orderly distribution, these support rod 3 also choose strong durable alloy material made, each group of support rod 3 both ends are connected with the inner wall of evaporator body 2 by welding technology or high-strength bolt fastening way, seamless and stable, so as to ensure that in the evaporator running process, can withstand various stress, for the subsequent installation of components to provide stable and reliable support foundation, between several groups of support rod 3, around the heating pipe 4, heating pipe 4 is spiral coil structure around the support rod 3 between, this unique structure greatly increases the heating area, makes the heating effect more uniform and efficient, heating pipe 4 surface is provided with electrode 5, electrode 5 is made of metal material with good conductivity and oxidation resistance, through special process and heating pipe 4 closely connected, ensure that the electric energy can be efficiently converted into heat energy, electrode 5 one end penetrates the outer wall of evaporator body 2, extends to the outside of evaporator body 2, in order to with the external power supply system convenient connection, for heating pipe 4 provides stable power supply, in the top of evaporator body 2, set up the crucial shunt cover plate assembly 6;
[0026] The core part of shunt cover plate assembly 6 is hollow shunt cover plate body 601, liquid pipe 602 and steam pipe 603 are respectively arranged on the top of shunt cover plate body 601, one end of liquid pipe 602 is connected with the external liquid conveying system, the other end is in smooth and close communication with the cavity of shunt cover plate body 601, to ensure that the liquid refrigerant can flow smoothly into the internal cavity of shunt cover plate body 601, one end of steam pipe 603 penetrates the cavity of shunt cover plate body 601 and extends to the bottom, and the bottom port is specially designed for airflow optimization, to ensure that the steam can be stably and efficiently discharged from the bottom of shunt cover plate body 601, several groups of shunt pipe 604 are uniformly distributed on the bottom of shunt cover plate body 601, which are communicated with the cavity of shunt cover plate body 601, the diameter, length and distribution spacing of shunt pipe 604 are strictly calculated and optimized, to uniformly and stably distribute the liquid refrigerant in the cavity of shunt cover plate body 601, so as to realize efficient evaporation process.
[0027] The welding process is adopted to realize the stable connection between the electrode 5 and the heating pipe 4 in the embodiment, which can withstand long-term current transmission and mechanical stress under complex working conditions, and provides a solid guarantee for the heating pipe 4 to stably obtain electric energy from the electrode 5. A locking bolt is carefully arranged at the position where the electrode 5 penetrates the evaporator main body 2. When the locking bolt is installed, a precise and suitable through hole is first reserved on the evaporator main body 2. After the electrode 5 is carefully penetrated through the through hole, the locking bolt is screwed into the pre-set threaded hole, and appropriate torque is applied by a professional torque tool to tightly press the sealing gasket between the electrode 5 and the evaporator main body 2. This not only effectively prevents the electrode 5 from loosening and displacing during long-term use, but also ensures the sealing of the evaporator main body 2, thereby ensuring the safe, stable and efficient operation of the evaporator.
[0028] In the embodiment, a sealing rubber ring 605 is installed at the joint between the shunt cover plate body 601 and the evaporator main body 2. The sealing rubber ring 605 is made of high-quality rubber material with high temperature resistance, chemical corrosion resistance and high elasticity, which can ensure long-term stable operation in the complex working environment of the evaporator. When the shunt cover plate body 601 and the evaporator main body 2 are assembled, the sealing rubber ring 605 is elastically deformed under the extrusion of the two, and the protruding part tightly fills the fine gap between the joint surfaces, further enhancing the sealing effect and effectively preventing the leakage of liquid and vapor inside the evaporator, thereby greatly improving the operation stability and safety of the entire evaporator system and reducing the risk of energy loss and equipment failure caused by leakage.
[0029] In the embodiment, the pipe diameter of the liquid pipeline 602 is significantly larger than that of the shunt pipe 604. The pipe diameter is designed to fully consider the input flow demand of the liquid refrigerant of the entire evaporator system. The larger pipe diameter can effectively ensure that the liquid refrigerant from the external supply source flows smoothly and efficiently into the internal cavity of the shunt cover plate body 601, and then cooperates with the relatively small shunt pipe 604 to reasonably disperse the large amount of liquid refrigerant flowing from the liquid pipeline 602 into the cavity of the evaporator main body 2, thereby realizing uniform distribution of the liquid refrigerant and ensuring that each part of the evaporator can obtain appropriate liquid amount for evaporation operation, thereby significantly improving the working efficiency and uniformity of the evaporation effect of the entire evaporator system.
[0030] In the internal structure of the evaporator body in this embodiment, the distribution pipe 604 is arranged inside the spiral coil structure of the heating pipe 4 in the vertical plane dimension, and when the liquid refrigerant is transported into the evaporator body through the distribution pipe 604 at the bottom of the distribution cover plate assembly 6, due to the unique position of the distribution pipe 604 inside the spiral coil structure of the heating pipe 4, the liquid refrigerant can quickly and maximally adhere to the heating surface of the heating pipe 4, greatly increasing the heat exchange area with the surrounding environment, quickly absorbing heat, and quickly realizing the phase change from liquid to gas, thereby greatly improving the evaporation efficiency of the evaporator and ensuring the efficient operation of the air conditioning refrigeration system.
