Description

节能机柜空调器  Energy-saving cabinet air conditioner
【技术领域】[Technical Field]
本发明涉及一种空调器，尤其涉及一种机柜空调器，特别为一种内部设有两种换热装置、可以根据空调环境与大气环境的温差情况适时选择更加合理的热量转移模式进行工作、从而降低能耗的节能机柜空调器，属于制冷设备技术领域。 The invention relates to an air conditioner, in particular to a cabinet air conditioner, in particular to an internal heat exchange device, which can select a more reasonable heat transfer mode according to the temperature difference between the air conditioning environment and the atmospheric environment. Therefore, the energy-saving cabinet air conditioner that reduces energy consumption belongs to the technical field of refrigeration equipment.
【背景技术】 【Background technique】
目前，众多对内部工作环境要求较高的工业或通讯设备，终年使用单一的传统蒸汽压缩式制冷设备进行控温，热量的转移依赖制冷设备单一的压缩制冷循环。由于此类制冷设备运行根据机柜内、外部的温度来控制调节，当机柜外的温度高于柜内温度时，启动压缩机制冷循环以实现热量由机柜内低温热源向机柜外高温热源的逆向转移。但当机柜外的环境温度低于机柜内温度时，热量则可以实现由机柜内高温热源向机柜外低温热源的自发转移，若此时仍然通过启动压缩机制冷循环来实现热量转移则不利于节约能源；而且，此种情况易造成压缩机反复启停，压缩机乃至制冷设备整机的使用寿命均会减短。At present, many industrial or communication equipment that require high internal working environment use a single traditional vapor compression refrigeration equipment for temperature control throughout the year. The heat transfer relies on a single compression refrigeration cycle of the refrigeration equipment. Since the operation of such refrigeration equipment is controlled according to the temperature inside and outside the cabinet, when the temperature outside the cabinet is higher than the temperature inside the cabinet, the compressor refrigeration cycle is started to realize the reverse transfer of heat from the low temperature heat source in the cabinet to the high temperature heat source outside the cabinet. . However, when the ambient temperature outside the cabinet is lower than the temperature inside the cabinet, the heat can be spontaneously transferred from the high-temperature heat source in the cabinet to the low-temperature heat source outside the cabinet. If the compressor is still started to start the heat transfer, it is not conducive to saving. Energy; Moreover, this situation is likely to cause the compressor to start and stop repeatedly, and the service life of the compressor and even the refrigeration equipment will be shortened.
从这类工业用空调器年使用情况看，密闭机柜内外温度高低的周期几乎相等，所以如果能使热量实现自发转移而不启动耗电量大的压缩机制冷装置或者实现二者的同时运行显然具有很大的节能减耗的优势。From the annual usage of such industrial air conditioners, the cycle of the temperature inside and outside the closed cabinet is almost equal, so if the heat can be spontaneously transferred without starting the compressor refrigeration device with large power consumption or the simultaneous operation of the two is apparent It has great advantages in energy saving and consumption reduction.
当今，已蓬勃发展的热管技术充分利用了热传导原理与制冷介质的快速热传递性质，透过热管将高温侧发热物体的热量迅速传递到低温热源处，其导热能力超过任何已知金属的导热能力。热管内热量传递是通过工质的相变过程进行的。由热管组成的热管换热器具有热管固有的传热量大、温差小、重量轻体积小、热响应迅速、风道易于分割、可靠性高等特点。但热管换热器是必须在温差存在的条件下实现热量单向传导转移，所以它的单一应用具有局限性。Today, the booming heat pipe technology makes full use of the heat transfer principle and the rapid heat transfer properties of the refrigerant medium. The heat of the high temperature side heat generating object is quickly transmitted to the low temperature heat source through the heat pipe, and its heat conduction capacity exceeds the heat conductivity of any known metal. . The heat transfer in the heat pipe is carried out through the phase change process of the working fluid. The heat pipe heat exchanger composed of the heat pipe has the characteristics of large heat transfer amount, small temperature difference, light weight and small volume, rapid heat response, easy division of the air passage, and high reliability. However, the heat pipe heat exchanger must realize the unidirectional conduction transfer of heat in the presence of temperature difference, so its single application has limitations.
因此，有必要提供一种节能空调器，其整合两种换热设备以克服现有技术的缺点。Accordingly, it would be desirable to provide an energy efficient air conditioner that integrates two heat exchange devices to overcome the shortcomings of the prior art.

【具体实施方式】 【detailed description】
工业上，用于降低电气柜或控制柜内温度的空调在使用时，柜内外的温度高低存在季节性差异，一年内，柜内温度高于或低于柜外温度的时间几乎相同。针对这种情况，本发明以在蒸汽压缩式制冷***内部集成热管式热交换***为思路，提出一种节能机柜空调器。Industrially, air conditioners used to reduce the temperature inside electrical cabinets or control cabinets have seasonal differences in temperature inside and outside the cabinet. Within a year, the temperature inside the cabinet is almost the same as or lower than the temperature outside the cabinet. In view of this situation, the present invention proposes an energy-saving cabinet air conditioner by integrating a heat pipe type heat exchange system inside a vapor compression refrigeration system.
热管是一种具有高导热性能的传热元件，它通过在全封闭真空管壳内工质的蒸发与凝结来传递热量，具有极高的导热性、良好的等温性、冷热两侧的传热面积可任意改变、可远距离传热、可控制温度等一系列优点。由热管组成的热管式热交换***具有传热效率高、流体阻损小、有利于控制露点腐蚀等优点。而且，热管式热交换***不需要压缩机，不需要氟利昂工质，其结构紧凑，质量和外形较小。The heat pipe is a heat transfer element with high thermal conductivity. It transfers heat by evaporation and condensation of the working medium in the fully enclosed vacuum envelope. It has extremely high thermal conductivity, good isothermality, and heat transfer on both sides of the hot and cold. The area can be arbitrarily changed, long-distance heat transfer, temperature control and other advantages. The heat pipe type heat exchange system composed of heat pipes has the advantages of high heat transfer efficiency, small fluid resistance loss, and favorable control of dew point corrosion. Moreover, the heat pipe type heat exchange system does not require a compressor and does not require a Freon working medium, and has a compact structure, a small mass and a small profile.
热管的工作原理是利用工作介质的蒸发与冷凝来传递热量。热管的工作介质根据成分和比例的不同，分为低温、中温和高温等几类热管，较为常见的工作介质有氨、水、丙酮及甲醇等。热管两端分别为蒸发端（加热端）和冷凝端（散热端），两端之间根据需要采取绝热措施。热管蒸发端受热时，管内工作流体汽化，从热源吸收汽化热，汽化后蒸汽向另一侧冷凝端流动并遇冷凝结向散热区放出潜热。冷凝液借毛细力或重力的作用回流，继续受热汽化，这样热管内热量通过工作介质的相变过程进行的往复循环传导，将大量热量从加热区传递到散热区。The heat pipe works by transferring heat from the evaporation and condensation of the working medium. The working medium of the heat pipe is divided into several types of heat pipes such as low temperature, medium temperature and high temperature according to the composition and proportion. The more common working mediums are ammonia, water, acetone and methanol. The two ends of the heat pipe are respectively an evaporation end (heating end) and a condensation end (heat radiating end), and heat insulation measures are taken between the two ends as needed. When the evaporation end of the heat pipe is heated, the working fluid in the pipe is vaporized, and the heat of vaporization is absorbed from the heat source. After vaporization, the steam flows to the condensation end of the other side and the condensation heat is released to the heat dissipation zone. The condensate is refluxed by the action of capillary force or gravity, and continues to be vaporized by heat, so that the heat in the heat pipe is transmitted through the reciprocating cycle of the phase change process of the working medium, and a large amount of heat is transferred from the heating zone to the heat dissipation zone.
热管式热交换***的热量转移需要在存在温差的条件下进行，其集成于常规蒸汽压缩式制冷***内部时，当机柜外环境温度较低而机柜内工作温度较高时，热管式热交换***便可以利用机柜内外温差散热。因此，在不必启动压缩机的情况下即可使机柜的柜内温度降低，起到调温的作用。而且，这种温差越大，热管式热交换***的散热功率就越大。这不仅节约了能源，而且延长了机柜空调器特别是压缩机等关键部件的使用寿命。The heat transfer of the heat pipe type heat exchange system needs to be carried out in the presence of a temperature difference. When integrated in a conventional vapor compression refrigeration system, the heat pipe type heat exchange system is used when the ambient temperature outside the cabinet is low and the operating temperature in the cabinet is high. You can use the temperature difference between the inside and outside of the cabinet to dissipate heat. Therefore, the temperature inside the cabinet can be lowered and the temperature can be adjusted without having to start the compressor. Moreover, the greater the temperature difference, the greater the heat dissipation power of the heat pipe heat exchange system. This not only saves energy, but also extends the service life of key components such as cabinet air conditioners, especially compressors.
热管式热交换***的应用局限性在于依赖机柜的内外温差，而且柜内温度的降低无法得到有效控制。在炎热的夏季或环境温度很高的时候，要实现热量的逆向转移时，热管式热交换***几乎失效。因此，将热管式热交换***集成在现有的蒸汽压缩式制冷***上，将极大地提高机柜空调器节能高效的品质。The application limitation of the heat pipe heat exchange system lies in the temperature difference between the inside and the outside of the cabinet, and the temperature reduction in the cabinet cannot be effectively controlled. In the hot summer or when the ambient temperature is high, the heat pipe heat exchange system is almost ineffective when the heat is reversely transferred. Therefore, integrating the heat pipe heat exchange system into the existing vapor compression refrigeration system will greatly improve the energy-saving and efficient quality of the cabinet air conditioner.
现有技术中，机柜的制冷***是一种蒸汽压缩式制冷***，用于对机柜进行温度控制。这种制冷***包括压缩机、蒸发器、冷凝器、节流元件以及电气组件等，蒸发器和冷凝器分别配有风机并设有各自的风道。将热管式热交换***集成到上述制冷***后，两套***复合使用，热管式热交换***的结构大小可依据换热量的多少进行设定。由电气组件组成的控制***根据环境温度以及机柜内温度等因素，判断启动蒸汽压缩式制冷***还是热管式热交换***，或者两套***同时运行。这样，可以使机柜空调器在外部工况比较寒冷的情况下免于启动压缩机，或者减少压缩机启动次数。而在炎热的夏季或者环境温度较高的时候，依赖压缩机进行制冷而不启动热管式热交换***。In the prior art, the refrigeration system of the cabinet is a vapor compression refrigeration system for temperature control of the cabinet. The refrigeration system includes a compressor, an evaporator, a condenser, a throttling element, and an electrical component, and the evaporator and the condenser are respectively equipped with fans and have respective air passages. After the heat pipe type heat exchange system is integrated into the above refrigeration system, the two systems are used in combination, and the structure size of the heat pipe type heat exchange system can be set according to the amount of heat exchange. The control system consisting of electrical components determines whether to start the steam compression refrigeration system or the heat pipe heat exchange system according to factors such as the ambient temperature and the temperature inside the cabinet, or the two systems operate simultaneously. In this way, the cabinet air conditioner can be prevented from starting the compressor or reducing the number of compressor starts when the external working conditions are relatively cold. In the hot summer or when the ambient temperature is high, the compressor is relied on for cooling without starting the heat pipe heat exchange system.
请参阅图1至图4，于本发明优选实施方式中，该节能机柜空调器100包括至少具有前面板11及后面板12的外壳体、收容在外壳体内的蒸汽压缩式制冷***3、热管式热交换***4及控制蒸汽压缩式制冷***3及热管式热交换***4的电气元件2。本发明节能机柜空调器100还包括将节能机柜空调器100分隔成相互隔绝的内循环换热***及外循环换热***的隔板5。Referring to FIG. 1 to FIG. 4, in a preferred embodiment of the present invention, the energy-saving cabinet air conditioner 100 includes an outer casing having at least a front panel 11 and a rear panel 12, a vapor compression refrigeration system 3 housed in the outer casing, and a heat pipe type. The heat exchange system 4 and the electrical components 2 that control the vapor compression refrigeration system 3 and the heat pipe heat exchange system 4. The energy-saving cabinet air conditioner 100 of the present invention further includes a partition 5 for dividing the energy-saving cabinet air conditioner 100 into an internal circulation heat exchange system and an external circulation heat exchange system which are isolated from each other.
于外壳体的前面板11分别开设有位于下部的柜外进风口110及位于上部的柜外出风口112。于外壳体的后面板12分别开设有位于上部的柜内进风口120及位于下部的柜内出风口122。The outer panel 11 of the outer casing is respectively provided with an outer air inlet 110 at the lower portion and an outer air outlet 112 at the upper portion. The air inlet 120 in the upper part of the cabinet and the air outlet 122 in the lower part are respectively arranged on the rear panel 12 of the outer casing.
蒸汽压缩式制冷***3包括安装于外壳体的底板13上的压缩机30、与柜内出风口122相对的蒸发器32、与柜内进风口120相对的蒸发辅助风机33、与柜外出风口112相对的冷凝器31及与柜外进风口110相对的冷凝辅助风机34。The vapor compression refrigeration system 3 includes a compressor 30 mounted on the bottom plate 13 of the outer casing, an evaporator 32 opposite to the air outlet 122 in the cabinet, an evaporation auxiliary fan 33 opposite to the air inlet 120 in the cabinet, and an air outlet 112 outside the cabinet. The opposite condenser 31 and the condensation auxiliary fan 34 opposite to the inlet air inlet 110.
热管式热交换***4包括与冷凝器31平行相对并临近冷凝器31内侧（后方）设置的冷凝端41及与蒸发器32平行相对并临近蒸发器32内侧（前方）设置的蒸发端42。冷凝端41与冷凝器31共用冷凝辅助风机34，蒸发端42与蒸发器32共用蒸发辅助风机33。The heat pipe type heat exchange system 4 includes a condensation end 41 disposed in parallel with the condenser 31 and disposed adjacent to the inside (rear) of the condenser 31, and an evaporation end 42 disposed in parallel with the evaporator 32 and disposed adjacent to the inside (front) of the evaporator 32. The condensation end 41 shares the condensation auxiliary fan 34 with the condenser 31, and the evaporation end 42 shares the evaporation auxiliary fan 33 with the evaporator 32.
于本发明优选实施方式中，热管式热交换***4的冷凝端41为平行流式换热结构，蒸发端42为管片式换热结构。平行流式换热结构包括位于上、下两端相互平行的上集流管411及下集流管412、及多个相互平行并串联在上、下集流管411、412之间的带有翅片的扁管410组成。上集流管411具有集流管入口4110，下集流管412具有集流管出口4120。集流管入口4110与集流管出口4120成斜对角设置（即，设置于冷凝端41的两侧）以加大工作介质流通面积，增强换热效果。平行流式换热结构工作流体流程相对较短，压损小，热损失少，换热效率较高，且体积小、防震效果好，重量轻。In a preferred embodiment of the present invention, the condensation end 41 of the heat pipe heat exchange system 4 is a parallel flow heat exchange structure, and the evaporation end 42 is a tube sheet heat exchange structure. The parallel flow heat exchange structure includes an upper header 411 and a lower header 412 which are parallel to each other at the upper and lower ends, and a plurality of parallel and parallel lines between the upper and lower headers 411 and 412 The flat tube 410 of the fin is composed. The upper header 411 has a header inlet 4110 and the lower header 412 has a header outlet 4120. The header inlet 4110 and the header outlet 4120 are disposed diagonally opposite to each other (ie, disposed on both sides of the condensation end 41) to increase the flow area of the working medium and enhance the heat exchange effect. The parallel flow heat exchange structure has a relatively short working fluid flow, small pressure loss, less heat loss, high heat exchange efficiency, small volume, good anti-vibration effect and light weight.
管片式换热结构具有多个带有翅片的U形铜管420、连接各个铜管420入口的分流装置421及连接各个铜管420出口的统一的集流管出口422。然而，U形铜管420仅为本发明的一个实施示例，其还可以为铝制管路或其他热交换性能较好的材质。分流装置421与集流管出口4120连通，接收来自冷凝端41的液态工作介质，集流管出口422与冷凝端41的集流管入口4110连通形成集流装置，用于将蒸发后的气态工作介质送入冷凝端41进行换热。管片式换热结构中，工作流体流通介质较长，铜管口径较大，工作流体阻力小，容易蒸发。而且，工作介质从冷凝端41的集流管出口4120中流出，经分流装置421后流入蒸发端42的U形铜管420时，由于在原有的冷凝端41的扁管410中，流路较窄，突然释放到较宽的铜管420流路中，流量一下变大，会有较好的换热效果。而本发明的铜管流路为多进多出结构，于本发明的优选实施方式中为三进三出，可以多回路释放，换热效果更好。The tube-sheet heat exchange structure has a plurality of finned U-shaped copper tubes 420, a flow dividing device 421 connecting the inlets of the respective copper tubes 420, and a unified header outlet 422 connecting the outlets of the respective copper tubes 420. However, the U-shaped copper tube 420 is only one embodiment of the present invention, and it may also be an aluminum tube or other material having better heat exchange performance. The flow dividing device 421 is in communication with the header outlet 4120, receives the liquid working medium from the condensation end 41, and the header outlet 422 communicates with the header inlet 4110 of the condensation end 41 to form a current collecting device for operating the vaporized state after evaporation. The medium is fed to the condensation end 41 for heat exchange. In the tube-sheet heat exchange structure, the working fluid circulates the medium, the copper tube has a large diameter, the working fluid has small resistance, and is easy to evaporate. Moreover, when the working medium flows out from the header outlet 4120 of the condensing end 41 and flows into the U-shaped copper tube 420 of the evaporation end 42 via the flow dividing device 421, the flow path is compared in the flat tube 410 of the original condensing end 41. Narrow, suddenly released into the wider copper tube 420 flow path, the flow will become larger, there will be better heat transfer. The copper tube flow path of the present invention is a multi-input and multi-out structure. In the preferred embodiment of the present invention, it is three-in and three-out, and can be released in multiple circuits, and the heat exchange effect is better.
然而，本发明中的冷凝端41并不仅限于平行流式换热结构，管片式换热结构、管带式换热结构均可以实现冷凝端41的功能。本发明中的蒸发端42也不仅限于管片式换热结构，平行流式换热结构、管带式换热结构均可以实现蒸发端42的功能。管带式换热结构包括多个散热管及与散热管集成的散热带，可能串有翅片。因为其为业内习知产品，此处不做具体介绍。However, the condensation end 41 in the present invention is not limited to the parallel flow heat exchange structure, and the tube-sheet heat exchange structure and the tube-and-tube heat exchange structure can realize the function of the condensation end 41. The evaporation end 42 in the present invention is not limited to the tube-sheet heat exchange structure, and the parallel flow heat exchange structure and the tube-and-tube heat exchange structure can realize the function of the evaporation end 42. The tube-and-belt heat exchange structure includes a plurality of heat-dissipating tubes and a heat-dissipating belt integrated with the heat-dissipating tubes, and may have fins. Because it is a well-known product in the industry, it will not be specifically introduced here.
此外，本发明中的热管式热交换***中，冷凝端41和蒸发端42的换热结构形式可以相同，也可以不同。而且，冷凝端41和蒸发端42也并不限于分体式结构，其还可以采用一体式结构并由隔板5分隔开。Further, in the heat pipe type heat exchange system of the present invention, the heat exchange structure forms of the condensation end 41 and the evaporation end 42 may be the same or different. Moreover, the condensing end 41 and the evaporating end 42 are also not limited to the split structure, and may be of a unitary structure and separated by the partition 5.
于本发明的优选实施方式中，蒸汽压缩式制冷***3的冷凝器31也采用了与冷凝端41近似的平行流式换热结构，蒸发器32也采用了与蒸发端42近似的管片式换热结构。该种设置有利于实现更为紧凑的布局，然而冷凝器31并不局限于平行流式换热结构，其也可以采用管片式或管带式，蒸发器32也并不局限于管片式换热结构，其也可以采用平行流式或管带式，均能实现本发明。In a preferred embodiment of the present invention, the condenser 31 of the vapor compression refrigeration system 3 also employs a parallel flow heat exchange structure similar to the condensation end 41, and the evaporator 32 also employs a tube type similar to the evaporation end 42. Heat exchange structure. This arrangement is advantageous for achieving a more compact layout, however, the condenser 31 is not limited to the parallel flow heat exchange structure, and may be of a tube type or a tube type, and the evaporator 32 is not limited to the tube type. The heat exchange structure, which can also be of a parallel flow or a tube belt type, can realize the present invention.
于本发明的优选实施方式中，蒸汽压缩式制冷***3的冷凝器31的平行流式换热结构的各个扁管沿水平方向延伸，而热管式热交换***4的冷凝端41的平行流式换热结构的各个扁管410沿竖直方向延伸，也就是与冷凝器31的扁管延伸方向垂直，该种排布方式更有利于机柜内外的气流走向，获得更好的换热效率。然而，冷凝器31与冷凝端41的扁管平行延伸方向同向设置也是可以实现本发明的。In a preferred embodiment of the present invention, the respective flat tubes of the parallel flow heat exchange structure of the condenser 31 of the vapor compression refrigeration system 3 extend in the horizontal direction, and the parallel flow type of the condensation end 41 of the heat pipe type heat exchange system 4 Each of the flat tubes 410 of the heat exchange structure extends in a vertical direction, that is, perpendicular to the direction in which the flat tubes of the condenser 31 extend. This arrangement is more advantageous for the airflow direction inside and outside the cabinet, and better heat exchange efficiency is obtained. However, it is also possible that the condenser 31 is disposed in the same direction as the parallel extending direction of the flat tubes of the condensation end 41.
工作时，由电气组件2组成的控制***根据机柜内与外部环境温度的实际情况，控制蒸汽压缩式制冷***3及热管式热交换***4的运行。当机柜内部温度比外部环境温度高时，控制***启动热管式热交换***4进行热量传导转移，此时蒸汽压缩式制冷***3可不工作或者同时辅助参与工作以满足温度调节需要。但当机柜内部温度比外部环境温度低时，则可直接启动蒸汽压缩式制冷***3将热量由低温密闭空间（机柜内）转移到高温外部环境中实现温度调节，因此可起到节能并延长压缩机30乃至机柜空调器100整体使用寿命的技术效果。During operation, the control system consisting of the electrical components 2 controls the operation of the vapor compression refrigeration system 3 and the heat pipe heat exchange system 4 according to the actual conditions of the temperature inside the cabinet and the external environment. When the internal temperature of the cabinet is higher than the external ambient temperature, the control system activates the heat pipe type heat exchange system 4 to perform heat transfer transfer. At this time, the vapor compression refrigeration system 3 may not work or assist in participating in the work to meet the temperature adjustment needs. However, when the internal temperature of the cabinet is lower than the external ambient temperature, the vapor compression refrigeration system 3 can be directly activated to transfer heat from the low-temperature sealed space (in the cabinet) to the high-temperature external environment for temperature adjustment, thereby saving energy and prolonging compression. The technical effect of the overall service life of the machine 30 and the cabinet air conditioner 100.
当蒸汽压缩式制冷***3工作时或热管式热交换***4工作时，机柜内部的热空气在蒸发辅助风机33的作用下，流经柜内进风口120、蒸发辅助风机33、蒸发端42及蒸发器32，将经过蒸发端42和/或蒸发器32冷却后的空气经柜内出风口122送入机柜内，对机柜进行降温。然后柜外的空气在冷凝辅助风机34的作用下，经柜外进风口110进入冷凝辅助风机34、冷凝端41及冷凝器31，将对冷凝器31和/或冷凝端41进行冷却后的热空气经柜外出风口112排出节能机柜空调器100外部。因此，蒸发端42与蒸发器32共用蒸发辅助风机33，冷凝端41与冷凝器31共用冷凝辅助风机34，结构紧凑。When the vapor compression refrigeration system 3 is in operation or the heat pipe heat exchange system 4 is operated, the hot air inside the cabinet flows through the air inlet 120, the evaporation auxiliary fan 33, the evaporation end 42 and the evaporation auxiliary fan 33. The evaporator 32 sends the air cooled by the evaporation end 42 and/or the evaporator 32 to the cabinet through the air outlet 122 of the cabinet to cool the cabinet. Then, the air outside the cabinet, under the action of the condensation auxiliary fan 34, enters the condensation auxiliary fan 34, the condensation end 41 and the condenser 31 through the outside air inlet 110, and heats the condenser 31 and/or the condensation end 41 after cooling. The air exits the outside of the energy-saving cabinet air conditioner 100 through the air outlet 112 of the cabinet. Therefore, the evaporation end 42 shares the evaporation auxiliary fan 33 with the evaporator 32, and the condensation end 41 and the condenser 31 share the condensation auxiliary fan 34, which is compact in structure.
具体来说，当热管式换热***4的冷凝端41为平行流式换热结构，而蒸发端42为管片式换热结构时，由于热管式换热***4内部为负压，冷凝端41内部的工作介质在冷却为液体后汇流至下集流管412，并经集流管出口4120流至分流装置421分流至各个铜管420的换热通道入口并流入换热通道。然后工作介质变为气体状态，由蒸发端42的集流管出口422集流入集流管入口4110然后进入蒸发端41的上集流管411，如此循环往复。Specifically, when the condensation end 41 of the heat pipe heat exchange system 4 is a parallel flow heat exchange structure, and the evaporation end 42 is a tube sheet heat exchange structure, since the inside of the heat pipe heat exchange system 4 is a negative pressure, the condensation end The internal working medium is cooled to a liquid and then merged to the lower header 412, and flows through the header outlet 4120 to the flow dividing device 421 to be branched to the heat exchange passage inlet of each copper tube 420 and flows into the heat exchange passage. The working medium then changes to a gaseous state, and the collector outlet 422 of the evaporation end 42 flows into the header inlet 4110 and then enters the upper header 411 of the evaporation end 41, thus circulating back and forth.
特别需要指出的是，本发明具体实施方式中仅以该节能机柜空调器100作为示例，在实际应用中其他类型的节能机柜空调器均适用本发明揭示的原理。对于本领域的普通技术人员来说，在本发明的教导下所作的针对本发明的等效变化，仍应包含在本发明权利要求所主张的范围中。It should be noted that, in the specific embodiment of the present invention, only the energy-saving cabinet air conditioner 100 is taken as an example, and other types of energy-saving cabinet air conditioners are applicable to the principles disclosed in the present invention. Equivalent variations of the inventions made within the teachings of the present invention are intended to be included within the scope of the appended claims.
