Description

Technical Field

[0001] This invention relates to the field of air refrigeration technology, specifically a V-shaped heat exchange evaporative cooler. Background Technology

[0002] Evaporative cooling heat exchange equipment, with its numerous advantages such as energy saving and environmental protection, low operating costs, simple overall structure, and convenient operation and maintenance, is widely used in air conditioning systems and industrial heat exchange scenarios in large places such as industrial plants, shopping malls, and data centers. It is mainly used to efficiently dissipate heat and cool the cooling medium inside air conditioning systems and heat exchange equipment, ensuring stable and low-energy operation of the entire heat exchange system. Its core working principle utilizes the physical property of water evaporation and heat absorption. Through the interaction of evaporation media such as wet curtains with heat exchanger components, heat is carried away from the heat exchanger body, thereby cooling the cooling medium flowing inside the heat exchanger. Compared with traditional pure air-cooled and compression-type heat exchange equipment, it has outstanding characteristics of low energy consumption, no pollutant emissions, and strong adaptability, aligning with the current development trend of green energy saving and efficient heat exchange in industrial equipment.

[0003] Currently, most mainstream evaporative heat exchange and cooling equipment on the market adopts a straight, fixed arrangement of internal heat exchange evaporation components, forming a straight-through airflow structure with the casing. This can basically meet the heat dissipation and cooling requirements of the heat exchanger and cooling medium. However, in actual engineering applications, this traditional straight-arrangement structure has significant inherent technical defects, greatly limiting the heat exchange performance and space adaptability of the equipment. It is difficult to meet the current requirements for high-power, miniaturized, and high-efficiency heat dissipation equipment, specifically in the following aspects: First, traditional flat layouts have low space utilization and poor equipment integration. Limited by the flat and regular single installation layout, the three-dimensional space inside the equipment box cannot be fully developed and utilized. Under the premise of fixed overall equipment size and installation footprint, it is impossible to expand the layout space of heat exchange evaporation components. The space adaptability is poor, and it is difficult to optimize heat dissipation configuration and improve heat dissipation performance without increasing the overall equipment size and installation space. It cannot meet the usage requirements of compact equipment installation scenarios.

[0004] Secondly, the effective heat exchange area of ​​traditional flat-layout structures is limited, resulting in a low overall heat exchange capacity. With a fixed external cabinet size, the flat component layout is structurally restrictive, failing to fully utilize the internal space to expand the effective placement area of ​​the heat exchangers and evaporative cooling pads, leading to a smaller overall effective heat exchange area. Under high-load heat exchange conditions, the heat exchangers' cooling capacity for the internal cooling medium is insufficient, making it difficult to effectively improve the overall heat exchange efficiency and meet the heat dissipation requirements of high-power heat exchange systems.

[0005] Finally, the traditional straight-flow duct structure results in a short airflow path and insufficient heat exchange. The traditional straight-flow duct structure leads to a short and fast airflow path for the external air intake. Air quickly passes through the heat exchange evaporator components and is directly exhausted by the fan, significantly shortening the contact time between the air and the evaporative cooling pad and heat exchanger. On the one hand, this results in insufficient evaporation of the water film on the evaporative cooling pad surface, preventing the full utilization of evaporative heat absorption efficiency and limiting the heat absorption and cooling effect on the heat exchanger itself. On the other hand, the air convection cooling effect is poor, and residual heat on the heat exchanger surface cannot be dissipated in time. Ultimately, this leads to incomplete heat dissipation, poor cooling effect of the cooling medium, and low overall energy utilization of the equipment.

[0006] In summary, existing evaporative heat exchange cooling equipment with a straight-line arrangement generally suffers from problems such as low utilization of the chamber space, small effective heat exchange area, short contact time between air components, poor medium cooling effect, and low energy utilization. It cannot simultaneously meet the core usage requirements of miniaturized and compact installation with efficient heat exchange. Therefore, there is an urgent need to design a novel V-shaped evaporative heat exchange cooler to address the shortcomings of existing technologies and improve the overall heat dissipation performance and adaptability of the equipment. Summary of the Invention

[0007] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0008] A V-shaped heat exchange evaporative cooler includes a housing, an air inlet on one side of the housing, an air outlet on the other side of the housing, a fan installed inside the housing, and two sets of heat exchange evaporation components.

The side of the two sets of heat exchange evaporation components that are close to each other corresponds to the air inlet, and the side that are spread out corresponds to the fan. The fan draws air from the air inlet side, drives the airflow through the heat exchange evaporation assembly, and then discharges it from the air outlet.

[0010] As a further aspect of the present invention: in each group of heat exchange evaporation components, the heat exchanger and the wet curtain are arranged parallel to each other and facing each other.

[0015] As a further aspect of the present invention: the side wall of the housing is provided with a side air inlet corresponding to one side of the two sets of heat exchange evaporation components that are spread out to each other; A filter screen is installed at both the side air inlet and the air inlet.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) The present invention adopts a V-shaped arrangement of two sets of heat exchange evaporation components, which is different from the traditional straight arrangement structure. It can make full use of the internal three-dimensional space of the box and effectively improve the space utilization rate. Without increasing the overall size of the equipment, the layout area of ​​the heat exchange evaporation components can be expanded, the effective heat exchange and heat dissipation area can be increased, and the drawbacks of the traditional straight structure, such as limited heat exchange area and low heat dissipation limit of the whole machine, can be overcome.

[0019] 2) The V-shaped layout forms a gradual air duct, which effectively extends the airflow path in the box and increases the contact time between the air and the heat exchange evaporation components. This allows the convective heat transfer and evaporative heat absorption processes to proceed more fully, avoiding the problems of excessively fast airflow and incomplete heat exchange in traditional straight-through short air ducts. This significantly improves the cooling effect of the cooling medium and the energy utilization rate of the equipment.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8 In this embodiment of the invention, a V-shaped heat exchange evaporative cooler can be widely used in supporting heat exchange and heat dissipation scenarios such as industrial plants, shopping malls, and data centers. It is mainly used to dissipate heat and cool down the cooling medium inside the heat exchange system. Overall, it has the characteristics of energy saving and environmental protection, low operating cost, simple structure, and convenient operation and maintenance, which is in line with the development trend of green and energy-saving equipment.

[0028] The equipment consists of a housing 1, an air inlet 2, an air outlet 3, a fan 4, and two sets of heat exchange evaporation components 5. The housing 1 is the overall load-bearing structure of the equipment, serving to enclose and fix the various components and guide airflow. The interior of the housing 1 forms a complete cavity for installation and airflow. An air inlet 2 is located on one side of the housing 1, and an air outlet 3 is located on the opposite side, forming a directional airflow channel with the internal structure to ensure orderly airflow. The fan 4 is fixedly installed inside the housing 1, corresponding to the air outlet 3, and is the power component for the airflow circulation of the equipment. When the fan 4 is working, it can draw in external air from the air inlet 2, driving a stable directional airflow inside the housing 1, so that the external airflow continuously washes the heat exchange evaporation components 5 and completes heat exchange. Finally, the airflow is discharged from the air outlet 3, continuously completing the heat dissipation and cooling operation of the heat exchanger 6 and the cooling medium.

[0029] Two sets of heat exchange evaporation components 5 form the core heat exchange and cooling structure of the equipment. Each set of heat exchange evaporation components 5 includes a heat exchanger 6 and a wet curtain 7. The heat exchanger 6 serves as the heat exchange carrier for the cooling medium, which circulates within the heat exchanger 6 and carries the system's waste heat (waste heat and load heat generated by the entire air conditioning / industrial heat exchange system). The wet curtain 7, as the evaporation medium, absorbs heat from the heat exchanger 6 by relying on the physical properties of water evaporation, thereby cooling the cooling medium inside the heat exchanger 6. This invention differs from the traditional straight layout structure by installing the two sets of heat exchange evaporation components 5 in a V-shaped arrangement inside the housing 1. The side of the two sets of heat exchange evaporation components 5 that is close to each other corresponds to the air inlet 2, and the side that is spread out corresponds to the fan 4, forming a V-shaped gradually changing air duct structure with a narrow opening to welcome the air inlet and an open opening to connect with the fan 4.

[0030] During actual operation, the fan 4 continuously draws in external air from the air inlet 2. The airflow first converges at the V-shaped converging point of the two sets of heat exchange evaporation components 5, and then flows along the two sets of inclined heat exchange evaporation components 5. Relying on the inclined component arrangement structure, the overall airflow path inside the housing 1 can be appropriately extended, allowing the airflow to better and more fully adhere to the water film on the surface of the wet curtain 7 and the surface of the heat exchanger 6 components, effectively increasing the contact time between the air and the evaporation medium and heat exchange components, facilitating the gradual and more thorough completion of the water evaporation heat absorption and gas-liquid heat exchange processes. Compared with the existing straight-line arrangement forming a short air duct structure, this invention, through the V-shaped structural layout, can fully utilize the internal three-dimensional space of the housing 1. Under the premise that the overall external dimensions and installation footprint of the equipment remain unchanged, it can effectively improve the internal space utilization rate of the housing 1, solving the problems of space waste and poor adaptability of the traditional straight layout. Meanwhile, the V-shaped inclined arrangement can effectively expand the effective heat exchange layout of heat exchanger 6 and wet curtain 7, increase the effective heat dissipation area, and overcome the drawbacks of the traditional flat structure which has limited heat exchange area and low heat dissipation limit.

[0031] Meanwhile, the V-shaped gradient air duct effectively improves the problems of rapid airflow and insufficient contact time in traditional straight air ducts. This further ensures that the evaporation and heat absorption process of the wet curtain 7 and the convective heat dissipation process between the air and the heat exchanger 6 can proceed more fully and completely. It can absorb heat from the heat exchanger 6 body more stably and efficiently, and promptly remove residual heat from the surface of the heat exchanger 6. To a certain extent, this improves the cooling effect of the heat exchanger 6 on the internal cooling medium, addressing the problems of incomplete heat exchange, poor medium cooling effect, and low energy utilization in traditional equipment. The invention has a simple overall structure, requiring no complex modifications. While retaining the original advantages of evaporative cooling equipment—energy saving, low consumption, and easy maintenance—it effectively balances the need for miniaturized installation space with the requirements of efficient heat exchange and heat dissipation. Its strong structural adaptability makes it highly valuable for application and promotion.

[0032] In this embodiment of the invention, in each heat exchange evaporation assembly 5, the heat exchanger 6 is arranged near the air inlet 2, and the evaporative cooling pad 7 is arranged near the fan 4, forming a front-to-back hierarchical assembly structure of the heat exchanger 6 and the evaporative cooling pad 7 in the direction of airflow. After the external air enters the housing 1 through the air inlet 2, it can preferentially directly wash over and cover the outer surface of the heat exchanger 6, using the convection effect of the fresh air at room temperature to carry away some of the heat on the surface of the heat exchanger 6 in advance, realizing pre-convection heat dissipation; the airflow after heat exchange continues to flow along the V-shaped air duct towards the fan 4, and then passes through the medium of the evaporative cooling pad 7 on the rear side. A water film can be continuously formed on the surface of the evaporative cooling pad 7. During the process of the airflow passing through the evaporative cooling pad 7, it can fully rely on the physical properties of water evaporation and heat absorption to further absorb the residual heat conducted to the surrounding area by the heat exchanger 6, forming a secondary cooling effect on the heat exchanger 6 body.

[0033] This hierarchical layout can adapt to the diversion and diffusion characteristics and orderly flow pattern of the V-shaped air duct, so that the heat exchange and evaporation heat absorption processes of airflow are carried out in a layered and orderly manner. Without changing the overall shape and size of the equipment, it can effectively improve the effective contact utilization rate between airflow and heat exchanger 6 and wet curtain 7, weaken the problem of disordered airflow heat exchange and insufficient effect in traditional structures, help to relatively improve the heat exchange and heat dissipation capacity of the whole machine, and improve the cooling effect of the cooling medium and the stability of the operating conditions to a certain extent.

[0034] In this embodiment of the invention, in each heat exchange evaporation assembly 5, the heat exchanger 6 and the evaporative cooling pad 7 are assembled in a parallel and facing arrangement, ensuring that the effective heat exchange surface of the heat exchanger 6 corresponds and matches the effective evaporation surface of the evaporative cooling pad 7, maintaining a regular and aligned relative position between the two surfaces. This parallel and facing layout guides the airflow to pass smoothly through the surfaces of the heat exchanger 6 and the evaporative cooling pad 7, reducing the probability of airflow deviation, local cavitation, and heat exchange dead zones, and making the airflow within the heat exchange evaporation assembly 5 more regular. Simultaneously, this structure allows the evaporative cooling area of ​​the evaporative cooling pad 7 to correspond to the heat dissipation area of ​​the heat exchanger 6, enabling the evaporative heat absorption effect generated by the evaporative cooling pad 7 to comprehensively cover the heat exchange area of ​​the heat exchanger 6. This effectively improves the alignment between the heat exchange area and the evaporative cooling area, resulting in a more balanced and sufficient overall heat exchange and evaporative heat absorption process. It improves the uneven local heat exchange effect, thereby helping to enhance the uniformity and operational stability of the overall heat exchange and heat dissipation of the heat exchange evaporative cooling machine.

[0035] In this embodiment of the invention, the inner sides of the two sets of heat exchange evaporation components 5 cooperate to form a confluence cavity 8, and the air inlet of the fan 4 is correspondingly located inside the confluence cavity 8. Combined with the V-shaped inclined arrangement of the components in this device, after the external airflow flows along the inclined plates of the two sets of heat exchange evaporation components 5 and completes the heat exchange process of convective heat transfer and evaporative heat absorption, it can gradually converge inwards and flow into the confluence cavity 8. The confluence cavity 8 can play a certain role in regulating, converging, and guiding the airflow after it has been diverted and diffused through the V-shaped air duct. This can improve the problem of chaotic airflow and inconsistent wind direction, reduce the probability of local eddies and airflow stagnation, and allow the airflow after heat exchange and cooling to relatively smoothly and centrally connect to the air inlet of the fan 4, and finally be stably discharged outwards through the exhaust action of the fan 4.

[0036] This structure, in conjunction with the aforementioned V-shaped gradient air duct, forms a graded airflow path, enabling the processes of airflow diversion for heat exchange, convergence and regularization, and negative pressure discharge to proceed in an orderly manner layer by layer. This can improve the smoothness and continuity of the airflow circulation inside the heat exchange evaporator to a certain extent, ensuring that the heat exchange effect of the heat exchange evaporator component 5 can be stably performed, and helping to relatively improve the heat exchange efficiency and operating condition adaptability of the entire machine.

[0037] In this embodiment of the invention, baffle structures are provided between the two sets of heat exchange evaporation components 5 and at the gaps between the heat exchange evaporation components 5 and the housing 1. These baffle structures effectively block and constrain the airflow inside the housing 1. Combined with the overall V-shaped air duct and the airflow layout of the inner confluence cavity 8, the baffle structures can, to a certain extent, block or reduce the direct flow of air from the outer gaps of the heat exchange evaporation components 5 into the confluence cavity 8, thus mitigating the phenomenon of bypass airflow directly entering the confluence cavity 8 without convective heat exchange by the heat exchanger 6 or evaporative cooling by the wet curtain 7. By limiting the intrusion of ineffective airflow from the outside, more external airflow can be guided along the preset air duct path through the surface of the heat exchange evaporation components 5, allowing the airflow to participate in the complete convective heat exchange and evaporative heat absorption process as much as possible. This reduces the generation of ineffective airflow, relatively increases the proportion of effective heat exchange airflow, ensures the flow order and heat exchange uniformity of the airflow inside the housing 1, and further optimizes the overall heat dissipation and heat exchange effect of the heat exchange evaporation cooler.

[0038] In this embodiment of the invention, the overall assembly structure of the aforementioned heat exchange evaporative cooler is adapted to the airflow obstruction and flow restriction requirements. The flow obstruction structure specifically includes an air inlet baffle 9, a side baffle 10, a top cover plate 11, and a lower baffle 12.

[0039] Among them, the air inlet baffle 9 is connected and arranged between the opposite sides of the two sets of heat exchange evaporation components 5 on the side that are close to each other. It can block and limit the flow in the middle gap of the V-shaped air inlet side, and can weaken the situation that the airflow directly passes through the gap from the air inlet 2 into the confluence chamber 8 and is discharged without heat exchange to a certain extent. The side baffles 10 are respectively installed between the side of the two sets of heat exchange evaporation components 5 on the side where they are unfolded and the inner wall of the box 1. They can form a shielding constraint on the lateral gap between the outer side of the heat exchange evaporation components 5 and the box 1, reducing the phenomenon of lateral airflow directly entering the confluence cavity 8 from the gap. The top cover plate 11 is connected and disposed between the tops of the two sets of heat exchange evaporation components 5. It can cover and limit the gap at the top of the two sets of heat exchange evaporation components 5, thereby weakening the situation where the top airflow bypasses the flow and directly enters the confluence cavity 8 without passing through the plate surface of the heat exchange evaporation components 5. The lower baffle 12 is respectively connected between the bottom of the two sets of heat exchange evaporation components 5 and the inner bottom of the box 1. It can block and limit the flow of the bottom connection gap, reducing the probability of the bottom airflow directly entering the confluence cavity 8.

[0040] The various baffle structures work together to form multi-directional enclosures and limits on the various gaps in the housing 1 from the air inlet side, sides, top, and bottom. This significantly reduces the possibility of bypass airflow that has not undergone sufficient heat exchange directly entering the manifold 8 through these gaps, greatly preventing such airflow from interfering with the main airflow. Through the coordinated operation of the various baffle structures, the airflow direction inside the housing 1 can be further regulated, guiding most of the airflow along the preset V-shaped airflow path through the heat exchange evaporation component 5, completing the entire process from convection heat exchange to evaporation heat absorption. This effectively weakens the adverse effects of ineffective airflow on the overall heat exchange operation, relatively improves the regularity of the airflow circulation inside the heat exchange evaporation cooler, and ensures the overall effectiveness and stability of the equipment's heat exchange operation.

[0041] In this embodiment of the invention, each heat exchange evaporation assembly 5 has a clamping plate 13 structure around its four edges. The evaporative cooling pad 7 can be securely mounted to the corresponding heat exchanger 6 with the help of the clamping plates 13, thereby achieving a relatively fixed assembly relationship between the evaporative cooling pad 7 and the heat exchanger 6. At the same time, the clamping plates 13 at each edge of the evaporative cooling pad 7 can be assembled with the corresponding air inlet baffle 9, side baffle 10, top cover plate 11, and lower baffle 12, respectively, so that the clamping plates 13 of the evaporative cooling pad 7 and the various airflow baffle structures of the whole machine form an integrated assembly structure that works in conjunction. This structural arrangement can improve the overall assembly integrity and structural stability of the evaporative cooling pad 7 inside the heat exchange evaporation assembly 5 to a certain extent, and reduce the possibility of the evaporative cooling pad 7 shifting or loosening during long-term operation of the equipment. Meanwhile, relying on the connection and cooperation between the clamping plate 13 and each baffle structure, it can further fill the small gaps at the structural connection position, which can help reduce the situation where a small amount of airflow bypasses the gaps at the edge of the wet curtain 7, further regulate the airflow direction inside the box 1, and enable more airflow to flow through the effective working area of ​​the wet curtain 7 and the heat exchanger 6 to participate in the heat exchange operation, thereby helping to improve the overall airflow regularity and heat exchange operation effect inside the heat exchange evaporative cooler.

[0042] In this embodiment of the invention, a side air inlet 14 is provided on the side wall of the housing 1 of the heat exchange evaporation cooler. The location of the side air inlet 14 corresponds to the side where the two sets of heat exchange evaporation components 5 are spread out. Considering the V-shaped layout of the equipment, the side where the two sets of heat exchange evaporation components 5 are close together corresponds to the main air inlet 2 of the housing 1, ensuring sufficient airflow. However, the side where they are spread out is relatively far from the main air inlet 2, which can easily lead to insufficient airflow and uneven air distribution, weakening the evaporative heat absorption and convective heat transfer effects in that area. Therefore, the side air inlet 14, located on the spread side of the heat exchange evaporation components 5, forms a compensating airflow structure with the main air inlet 2 of the housing 1. This supplements the airflow in the areas on both sides of the V-shaped structure, improving the problem of insufficient airflow and poor air circulation on the spread side of the heat exchange evaporation components 5, resulting in a more balanced overall airflow distribution for the two sets of heat exchange evaporation components 5.

[0043] Meanwhile, the air inlet 2 and side air inlet 14 of the housing 1 are each equipped with a filter screen 15. The filter screen 15 can filter and intercept the external air entering the housing 1 through the air inlet 2 and side air inlet 14, which can relatively reduce the probability of dust, lint, and other impurities in the air entering the housing 1, and reduce the possibility of impurities adhering to the surface of the heat exchanger 6, the surface of the wet curtain 7, and the surfaces of various baffle structures. This structural configuration can maintain the cleanliness of the heat exchange evaporation component 5 to a certain extent, avoid the adverse conditions such as air duct blockage and heat exchange efficiency reduction caused by impurity accumulation, balance the air volume of the whole machine, optimize the overall heat exchange effect, and help to relatively ensure the heat exchange stability and ventilation smoothness during the long-term operation of the heat exchange evaporation cooler.

[0044] In a preferred embodiment, a filter screen 15 may be added to the side of the heat exchanger 6 away from the wet curtain 7. This filter screen 15 can perform secondary filtration on the airflow entering the housing 1, further blocking residual dust and impurities in the airflow, preventing them from adhering to the surface of the heat exchanger 6 fins, reducing the risk of fin scaling and clogging, thereby ensuring the long-term heat exchange efficiency and heat dissipation performance of the heat exchanger 6.

[0045] In this embodiment of the invention, the housing 1 is equipped with a water supply structure, which includes a water distribution pipe assembly 22. The water distribution pipe assembly 22 is mounted on top of the evaporative cooling pad 7, and the water distribution pipe assembly 22 can be installed and fixed using the water passage reserved in the top cover plate 11. After external water enters the water distribution pipe assembly 22 through the pipes, it can be sprayed evenly downwards onto the evaporative cooling pad 7, forming a continuous and uniform water film on the surface of the evaporative cooling pad 7, thus meeting the water requirements for the equipment's evaporative heat exchange operation.

[0046] The bottom of the housing 1 is equipped with a water pump 23, an inlet valve assembly 24, and a drain valve assembly 25. It also integrates a heat exchanger inlet pipe connector 16, a heat exchanger outlet pipe connector 17, an inlet connector 20, and a drain connector 21. The inlet connector 20 is connected to the inlet valve assembly 24 and the water pump 23 via pipelines, and then to the top water distribution pipe assembly 22. The inlet valve assembly 24 controls the water flow and inlet flow. After being pressurized by the water pump 23, the water is delivered to the water distribution pipe assembly 22, achieving a stable spray water supply to the evaporative cooling pad 7. Excess water flowing down the surface of the evaporative cooling pad 7 collects at the bottom of the housing 1 and can be discharged in a timely manner by the drain valve assembly 25 in conjunction with the drain connector 21. This allows for appropriate water replacement within the housing 1, preventing long-term stagnation of water, heat accumulation, and impurity deposition, thus maintaining water quality and stable heat exchange conditions.

[0047] The heat exchanger inlet pipe joint 16 and the heat exchanger outlet pipe joint 17 are connected to the heat exchanger 6 inlet pipe 18 and outlet pipe 19, respectively, to realize the circulation of the cooling medium and provide a stable flow channel for the cooling medium to carry waste heat and complete the heat exchange and cooling cycle. The overall water circuit structure is well-organized. Through the top water distribution pipe assembly 22, the bottom water pump 23, various valves and pipe joints form a complete and controllable water supply, circulation and drainage system, which can continuously and stably supply water to the wet curtain 7, ensuring the stable and reliable operation of the heat exchange evaporative cooling machine.

[0048] The wet curtain 7 is a fiber or paper filler with a porous capillary structure, forming a large number of interconnected micro channels inside. After water is supplied to the wet curtain 7 by spraying from the top, it can diffuse and penetrate evenly throughout the wet curtain 7 under the combined action of gravity and capillary action, so that a uniform water film is formed throughout the wet curtain 7, ensuring uniform and stable evaporative heat exchange effect.

[0049] In summary, the beneficial effects of the present invention are as follows: 1) The present invention adopts a V-shaped arrangement of two sets of heat exchange evaporation components 5, which is different from the traditional straight arrangement structure. It can make full use of the internal three-dimensional space of the box 1 and effectively improve the space utilization rate. Without increasing the overall size of the equipment, the layout area of ​​the heat exchange evaporation components 5 can be expanded, the effective heat exchange and heat dissipation area can be increased, and the drawbacks of the traditional straight structure with limited heat exchange area and low heat dissipation limit of the whole machine can be overcome.

[0050] 2) The V-shaped layout forms a gradual air duct, which effectively extends the airflow path in the housing 1, increases the contact time between the air and the heat exchange evaporation component 5, and makes the convection heat exchange and evaporation heat absorption process more complete. This avoids the problem of excessively fast airflow and incomplete heat exchange in traditional straight-through short air ducts, and significantly improves the cooling effect of the cooling medium and the energy utilization rate of the equipment.

[0051] 3) The two sets of heat exchange evaporation components 5 are enclosed on the inner side to form a confluence cavity 8. With the help of the baffle structure, the internal airflow direction can be standardized, ineffective bypass airflow can be reduced, and the airflow can be guided to fully participate in heat exchange along the preset path, making the airflow organization of the whole machine more reasonable.

[0052] 4) The addition of a side air inlet 14 can provide supplemental air to the unfolded side of the V-shaped heat exchange evaporation component 5, solving the problem of uneven air volume on one side and making the overall air distribution more balanced; the air inlet 2 and the side air inlet 14 are equipped with filter screens 15, which can block impurities from entering the housing 1, avoid dust accumulation and blockage of the heat exchange evaporation component 5, and ensure the long-term efficient and stable operation of the equipment.
