Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a multi-layer hybrid high-efficiency condenser. Background Technology

[0002] Condensers, as key components in heat exchange systems, are widely used in chemical, power, and refrigeration industries. Their main function is to condense high-temperature steam or gas into liquid through a heat exchange process. In existing technologies, common condenser structures include shell-and-tube condensers, plate condensers, and spiral tube condensers, each with its own advantages and disadvantages, and are widely used in various operating conditions.

[0003] Shell-and-tube condensers use multiple linearly arranged metal tubes for heat exchange through the temperature difference between the fluid in the shell and tube sides. They are simple in structure and easy to manufacture, but their heat exchange efficiency is limited, and their large size makes them unsuitable for integration and lightweight design. Plate condensers consist of multiple stacked corrugated metal plates, with fluid flowing between adjacent plates for heat exchange. They have advantages such as high heat exchange efficiency and compact structure, but their internal channels are prone to scaling and blockage, and their pressure resistance is relatively poor. Spiral tube condensers use spiral coils to form heat flow channels, which can enhance fluid turbulence and heat transfer capabilities. However, their manufacturing process is complex, their volume utilization rate is low, and they are prone to turbulence and localized subcooling under high-flow conditions.

[0004] In summary, existing condenser structures still have many limitations in terms of heat exchange efficiency, structural strength, and fluid organization, mainly reflected in:

[0005] Limited heat exchange efficiency: Most existing condensers have two-dimensional or regular channel structures, which limit the contact area between hot and cold fluids, and the flow path is short, resulting in insufficient heat exchange surface area and limiting the overall condensation efficiency.

[0006] The contradiction between structural strength and volume utilization is prominent: plate and tube condensers cannot guarantee both heat transfer efficiency and strength and pressure resistance. They are prone to fatigue deformation or local stress accumulation, which affects long-term operational reliability.

[0007] The fluid flow path is singular, and the turbulence effect is limited: In spiral or direct-flow structures, hot and cold fluids flow in a fixed direction within the structure, making it difficult to achieve sufficient spatial crossover and flow velocity optimization, which affects the uniformity of heat exchange.

[0008] Low degree of structural integration and modularization: It is difficult to flexibly add or remove modules according to heat exchange requirements, which is not conducive to large-scale adjustment or equipment standardization.

[0009] Therefore, there is an urgent need for a condenser structure that is novel, has high heat exchange efficiency, high strength, and is easy to modularly expand, in order to solve the above-mentioned technical problems and improve overall performance. Utility Model Content

[0010] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0011] Therefore, the technical solution adopted by this utility model is as follows: a multi-layered hybrid high-efficiency condenser, comprising: a condenser box and several condensation plates disposed inside it. The condensation plates are stacked sequentially, forming alternating hot flow layers and cold liquid layers between them, constructing a flow space in which hot and cold fluids are separated and interleaved. The condenser box is provided with a coolant inlet and outlet, a steam inlet and a gas outlet, forming independent coolant circulation loops and steam condensation loops respectively, ensuring that the two fluids flow separately and do not interfere with each other. The condensation plates are composed of several plates, with guide ports on the upper and lower sides of the plates, and several flow channels arranged around the outer periphery of the guide ports. The flow channels have multiple flow holes communicating with the guide ports. This structure allows the fluid to enter from the guide ports, be evenly distributed in the flow channels through the flow holes, and exchange heat with the fluids in the hot flow layers or cold liquid layers formed by adjacent plates.

[0012] Specifically, this structure enables zoned and disturbed flow of hot and cold fluids in different spaces, effectively increasing the heat exchange area and efficiency per unit volume, while reducing local heat accumulation and improving heat exchange uniformity.

[0013] In a preferred embodiment, the condenser box is further configured such that: the top of the condenser box is provided with a coolant outlet and a gas outlet, and the bottom is provided with a coolant inlet and a steam inlet. The coolant passage connects all the cold liquid layers through multiple condensation plates, and the steam passage connects all the heat flow layers, forming two fluid loops with independent structures.

[0014] Specifically, this structure ensures that the coolant and steam circulate independently, avoiding thermal flow disturbances and flow short circuits, which is conducive to achieving a stable and efficient heat exchange process.

[0015] In a preferred embodiment, the condenser box is further configured such that caps are provided at the condenser trays at the top and bottom of the condenser box, near the coolant outlet and inlet, respectively, to seal the beginning and end of the coolant flow path and prevent coolant leakage or backflow.

[0016] Specifically, this structure achieves complete closure and flow guidance of the coolant circuit, improves the control accuracy of liquid flow, and avoids liquid leakage from off-design paths.

[0017] In a preferred embodiment, the condensation plate is further configured such that the plate is composed of hexagonal honeycomb units, each unit constructing the flow channel surface based on the Costa triple surface, which has uniform disturbance, high symmetry and minimum curvature characteristics.

[0018] Specifically, the design optimizes the fluid disturbance mode and channel arrangement through geometric configuration, improves the flow organization and path diversity of hot and cold media, achieves higher heat exchange capacity per unit area, and enhances structural rigidity and resistance to deformation.

[0019] In summary, this invention provides a compact, efficient, and modularly expandable high-efficiency condenser solution through structural optimization of the condensation plate, three-dimensional flow separation design of hot and cold fluids, and Costa surface configuration of the honeycomb unit. It is suitable for various high-temperature steam condensation and waste heat recovery scenarios.

[0020] The beneficial effects achieved by this utility model are as follows:

[0021] 1. In this utility model, by setting multiple alternating cold liquid layers and hot flow layers inside the condenser box, combined with a multi-layer condenser plate structure with flow channel pipes and flow channel holes, the cold and hot fluids are staggered in three-dimensional space to achieve heat exchange, which effectively improves condensation efficiency and reduces thermal resistance. It is suitable for high-throughput and high-heat-exchange-demand applications.

[0022] 2. In this utility model, a hexagonal honeycomb structure unit based on the Costa triple surface is adopted, which enables the condenser to have high structural strength and rigidity, while optimizing fluid disturbance and velocity distribution. This not only enhances the heat exchange area but also effectively reduces turbulence loss, achieving a balance between lightweight structure and high performance. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a multi-layered, high-efficiency hybrid condenser.

[0034] Combination Figures 1-5 As shown, this utility model provides a multi-layer hybrid high-efficiency condenser, including a condenser box 100. The condenser box 100 has a hollow cavity structure, and its shape can be cylindrical, square, or other compact forms. In this embodiment, the outer shell of the condenser box 100 adopts a ribbed reinforcing structure to improve overall strength and increase heat exchange area.

[0035] The condenser box 100 has a coolant outlet 120 and a gas outlet 140 at the top and a coolant inlet 110 and a steam inlet 130 at the bottom, for introducing coolant and steam respectively, and for discharging the cooled liquid and condensed gas.

[0036] like Figure 2 As shown, the condenser box 100 has several condensation plates 200 inside, which are stacked and assembled vertically. Two types of functional layers are formed between adjacent condensation plates 200: a heat flow layer 210, which is a channel for steam flow and heat exchange; and a coolant layer 220, which is a channel for coolant flow. The heat flow layer 210 and the coolant layer 220 are arranged alternately inside the condenser, forming a three-dimensional staggered flow structure, realizing interwoven heat transfer of hot and cold fluids in multiple directions.

[0037] like Figure 3 , Figure 4The condensation plate 200 is composed of multiple plates 201. Each plate 201 has a flow guide 202 on its upper and lower surfaces. The flow guide 202 has a central hexagonal opening structure, located on the upper and lower surfaces of the plate 201, and is used to communicate with the channels of adjacent plates. Several flow channels 203 are arranged around the outer periphery of the flow guide 202. The flow channels 203 can be hexagonal or fan-shaped structures and have good guiding performance.

[0038] like Figure 4 and 5 As shown, each of the flow channels 203 has several flow holes 204 on its inner side. These flow holes 204 are all connected to the guide ports 202, forming branch channels for the flow of coolant or steam. The top guide port 202 of the shelf 201 extends through the flow channels 203 arranged on its outer periphery to the bottom guide port 202. Fluid can be diverted, turbulent, and exchanged through the multiple flow holes 204. It is worth noting that the flow channels 203 and flow holes 204 are staggered along the circumferential direction on the upper and lower sides of the shelf 201, allowing the coolant and steam to flow alternately in three-dimensional space, avoiding thermal short-circuiting and enhancing heat exchange efficiency.

[0039] like Figure 2 As further shown, the coolant inlet 110 and coolant outlet 120 are respectively connected to multiple cold liquid layers 220. The coolant flows from bottom to top, passing sequentially through the cold liquid layers 220 in the multiple condensation plates 200, absorbing the latent heat released by the steam in the heat flow layer 210, and then exiting from the coolant outlet 120. Steam enters from the steam inlet 130, flows upward through the multiple heat flow layers 210, and continuously exchanges heat with the cold liquid layers 220 during the flow process, finally exiting as condensed gas at the gas outlet 140. This forms two independent fluid loops.

[0040] like Figure 2 As shown, to achieve complete closure and sealing of the two circuits, a cap 230 is provided on the guide port 202 near the coolant outlet 120 in the uppermost condenser plate 200 of the condenser box 100 to block the guide port 202 at this location and prevent coolant from flowing out of the casing. Similarly, a cap 230 is also provided on the guide port 202 near the coolant inlet 110 in the lowermost condenser plate 200 of the condenser box 100 to close the lower end of the circuit and achieve complete guidance of the coolant passage.

[0041] like Figure 5As shown, the single condenser plate 200 employs a spatial structure based on the Costa triple-curved surface configuration. Each unit is constructed with hexagonal boundaries, and its internal flow paths are nested through three-dimensional rolled surfaces, forming a bidirectional channel intersection structure. Coolant flows through the blue channel from bottom to top through the cold liquid layer 220, while steam flows through the red channel from bottom to top through the heat flow layer 210. The two fluids are interleaved in three-dimensional space but do not interfere with each other, achieving efficient heat exchange. Compared with traditional spiral tube or plate condensers, this structure maintains high strength while achieving higher heat exchange efficiency.

[0042] Working principle and usage process of this utility model:

[0043] This invention achieves efficient heat exchange between heat flow and coolant by arranging multiple condensation plates 200 inside the condenser box 100, creating alternating heat flow layers 210 and coolant layers 220. Each plate 201 utilizes its double-sided guide ports 202, flow channels 203, and flow holes 204 to allow heat flow and coolant to flow in different channels and transfer heat alternately.

[0044] Heat flow path (steam): Steam enters from the steam inlet 130 at the bottom of the condenser box 100, rises through the heat flow layer 210 of the condenser plate 200, exchanges heat with the coolant in the adjacent cold liquid layer 220 and condenses, and finally exits from the gas outlet 140 at the top.

[0045] Coolant path: The coolant enters from the coolant inlet 110 at the bottom, flows through each coolant layer 220 to absorb heat and rise in temperature, and is discharged from the coolant outlet 120 at the top.

[0046] Advantages of the heat exchange structure: The condensation plate 200 adopts an interlocking, staggered multi-channel structure, with each unit plate consisting of hexagonal structural units (such as...). Figure 5 It consists of two fluids, with the flow channel 203 arranged around the flow guide 202 and containing the flow channel hole 204. The two fluids flow alternately in the three-dimensional structure, which effectively enhances the heat transfer efficiency, avoids thermal short circuit, and optimizes the fluid distribution.

[0047] Usage process:

[0048] Equipment connection and installation: Connect the coolant inlet 110 at the bottom of the equipment to the coolant supply pipeline; connect the steam inlet 130 to the steam source; connect the coolant outlet 120 at the top to the coolant recovery or cooling system; connect the gas outlet 140 at the top to the condensate gas collection or discharge pipeline.

[0049] Start-up: Start the coolant pump to allow coolant to enter from the coolant inlet 110 and flow upward into multiple cold liquid layers 220; at the same time, steam enters the hot flow layer 210 from the steam inlet 130 and flows upward along the staggered path to exchange heat with the cold liquid layers.

[0050] Heat exchange process: Steam is heated and condensed into liquid or low-temperature gas by the coolant in the hot flow layer; the coolant absorbs heat from the steam and rises in temperature after passing through each cold liquid layer, and takes away the heat; the condensed gas or excess pressure is discharged from the gas outlet 140, and the coolant flows out from the coolant outlet 120.

[0051] Circulation and maintenance: Continuous condensation operation enables efficient heat exchange.
