技术领域 technical field
本实用新型属于冷热能量输运技术领域，涉及一种将热管系统和热泵系统系统相复合形成的进行冷热能量输运的多级热管热泵复合系统。 The utility model belongs to the technical field of cold and heat energy transportation, and relates to a multi-stage heat pipe heat pump compound system for cold and heat energy transportation formed by combining a heat pipe system and a heat pump system.

信息机房、基站类建筑中, 室内设备的发热量非常大, 达200~ 1000W/ m2。而且室内IT 设备全年8760h运行, 因此大多数情况下全年需要供冷, 其空调能耗非常大, 常占到信息机房、基站整体能耗的40%~50%。传统机房空调采用压缩机制冷方式全年运行, 而实际上在冬天或者过渡季节室外温度低于室内温度时, 完全可以利用室外低温空气作为冷源对室内供冷, 而不需要压缩机。热管换热器就是一种利用温差驱动制冷剂循环实现热量传递的设备, 由于其不需要压缩机, 可凭借制冷剂的蒸发和冷凝过程传递热量, 具有超导热性和等温特性, 被广泛应用于航天航空、空调、化工、炼油等领域。将热管换热器应用在只有显热传递的信 In information equipment rooms and base station buildings, the heat generated by indoor equipment is very large, reaching 200~1000W/m 2 . In addition, indoor IT equipment runs 8760h throughout the year, so cooling is required throughout the year in most cases, and its air conditioning consumes a lot of energy, often accounting for 40% to 50% of the overall energy consumption of information equipment rooms and base stations. Traditional computer room air conditioners use compressor cooling to run throughout the year. In fact, in winter or transitional seasons, when the outdoor temperature is lower than the indoor temperature, the outdoor low-temperature air can be used as a cold source to cool the room without a compressor. The heat pipe heat exchanger is a device that uses temperature difference to drive the refrigerant cycle to achieve heat transfer. Because it does not require a compressor, it can transfer heat by virtue of the evaporation and condensation of the refrigerant. It has superthermal conductivity and isothermal characteristics, and is widely used. Used in aerospace, air conditioning, chemical industry, oil refining and other fields. Applying heat pipe heat exchangers to signals where only sensible heat is transferred

It also solves some disadvantages of gas-liquid separation and unstable circulation during cooling of the existing heat pump refrigeration device, and improves the cooling heat transfer efficiency, but the discharge temperature of the exhaust port is very high. , the heat loss is still large.

The constant temperature characteristic of the refrigerant inside the single-stage heat pipe heat exchanger leads to a large heat loss of the heat pipe heat exchange device. Based on the above, this application can increase the number of heat pipe stages to have Changing the intermediate medium with constant temperature characteristics to medium with variable temperature characteristics and increasing the number of heat pump stages are effective ways to reduce the loss of heat exchange temperature difference and improve the total heat exchange efficiency. The single-stage heat pipe heat exchanger is changed to a multi-stage form, and the refrigerant in each heat pipe is regarded as a constant temperature fluid, so the multi-stage heat pipe can realize a heat exchange device with a variable temperature effect, and the heat exchange area of each heat exchanger is the same , the final discharge temperature is close to the ambient temperature, thereby maximizing the utilization rate of heat energy; changing the single-stage heat pump system to a multi-stage design can also better match the dynamic cooling load of the refrigeration system, and the structure of the entire system is simple, Environment friendly.

当使用多级热泵制冷工作模式时，压缩机（61；62；63）开启，单向阀（111；113；115）处于导通状态，同时循环泵（81；82；83）关闭，电磁阀（101；102；103）和单向阀（112；114；116）处于关闭状态，由于压缩机（61；62；63）的抽压力，单向阀（112；114；116）所在支路几乎没有制冷工质的通过，这样液态冷凝剂在蒸发器（41；42；43）中吸热降低室内温度，吸热后的液态冷凝剂变成气态，通过压缩机（61；62；63）压缩气态制冷剂变成高温高压状态，高温高压气态制冷剂通过冷凝器（51；52；53）导气管进入冷凝器（51；52；53）中，然后高温高压气态制冷剂在冷凝器（51；52；53）中散热变成液态制冷剂，液态制冷剂在高压气态制冷剂的推动下进入储液稳流器（71；72；73）中，气液制冷中间介质根据各自物理性质在储液罐内分离，高压液态中间介质经单向阀（111；113；115）进入节流阀（91；92；93），进行减压节流进入到蒸发器（41；42；43）中进行下一次循环。 When the multi-stage heat pump cooling mode is used, the compressor (61; 62; 63) is turned on, the one-way valve (111; 113; 115) is in the conduction state, and the circulation pump (81; 82; 83) is turned off at the same time, the solenoid valve (101; 102; 103) and the one-way valve (112; 114; 116) are in the closed state, due to the suction pressure of the compressor (61; 62; 63), the branch where the one-way valve (112; 114; 116) is located is almost There is no passage of refrigerant, so that the liquid condensing agent absorbs heat in the evaporator (41; 42; 43) to reduce the indoor temperature, and the liquid condensing agent after absorbing heat becomes gaseous and compressed by the compressor (61; 62; 63) The gaseous refrigerant turns into a high-temperature and high-pressure state, and the high-temperature and high-pressure gaseous refrigerant enters the condenser (51; 52; 53) through the air guide pipe of the condenser (51; 52; 53), and then the high-temperature and high-pressure gaseous refrigerant enters the condenser (51; 52; 53), the heat dissipation becomes liquid refrigerant, and the liquid refrigerant enters the liquid storage stabilizer (71; 72; 73) under the push of the high-pressure gas refrigerant, and the gas-liquid refrigeration intermediate medium is in the liquid storage according to their physical properties. Separation in the tank, the high-pressure liquid intermediate medium enters the throttle valve (91; 92; 93) through the check valve (111; 113; 115), and enters the evaporator (41; 42; 43) for decompression and throttling. one cycle.
使用多级热管制冷工作模式时，压缩机（61；62；63）关闭，单向阀（111；113；115）也处于截止状态，循环泵（81；82；83）开启，电磁阀（101；102；103）和单向阀（112；114；116）处于导通状态，循环泵（81；82；83）从储液稳流器（71；72；73）内抽取配有一定比例的二相流制冷工质，经电磁阀（101；102；103）进入蒸发器（41；42；43），蒸发器（41；42；43）与高温热源接触，液态工作介质在蒸发器（41；42；43）内受高温热源的加热而蒸发为气体，并吸收热量，蒸发形成的气体和部分没有蒸发的液体中间介质在高速流动中相互混合形成气液二相流体，它们从蒸发器（41；42；43）中输出，经单向阀（112；114；116）进入冷凝器（51；52；53），冷凝器（51；52；53）与低温热源接触，气态工作介质在冷凝器（51；52；53）内受低温热源的冷却而冷凝为液体，并放出热量，冷凝形成的液体工作介质在循环泵（81；82；83）的抽压力作用下，经冷凝器（51；52；53）导液管进入储液稳流器（71；72；73）中，其进行气液分离、储存与分流，进行下一次循环。 When the multi-stage heat pipe cooling mode is used, the compressor (61; 62; 63) is closed, the one-way valve (111; 113; 115) is also in the cut-off state, the circulation pump (81; 82; 83) is opened, and the solenoid valve (101 ; 102; 103) and the one-way valve (112; 114; 116) are in the conduction state, and the circulation pump (81; 82; 83) draws a certain proportion of The two-phase flow refrigerant enters the evaporator (41; 42; 43) through the solenoid valve (101; 102; 103), and the evaporator (41; 42; 43) is in contact with a high-temperature heat source, and the liquid working medium is in the evaporator (41 ; 42; 43) is heated by a high-temperature heat source to evaporate into a gas and absorb heat. The gas formed by evaporation and part of the liquid intermediate medium that has not evaporated are mixed with each other in high-speed flow to form a gas-liquid two-phase fluid. They flow from the evaporator ( 41; 42; 43), enter the condenser (51; 52; 53) through the check valve (112; 114; 116), and the condenser (51; 52; 53) is in contact with the low-temperature heat source, and the gaseous working medium is condensed Cooled by the low-temperature heat source in the container (51; 52; 53), it condenses into a liquid and releases heat.

这样这种多级热管热泵复合系统可以根据室内所需设定温度和室外温度的差异，选择性地运行多级热泵制冷工作模式或多级热管制冷工作模式，并且可以根据需要避免“大马拉小车”的情况，选择使热泵制冷工作模式或热管制冷工作模式的部分单元相互替代间歇性的工作，在保证室内降温要求的前提下达到节能运行；当室外温度较高或者室内负荷过大时，多级热管热泵复合系统运行热泵制冷工作模式，工作原理与一般变频或者非变频空调相同，室内的热量通过蒸汽压缩制冷循环散至室外空间，达到室内空间的降温冷却效果；当室外温度低于室内温度一定值时，压缩机组关闭，机组自动进入热管制冷工作模式，通过热管节能模块把气态制冷剂带至冷凝器中冷凝放热，最后成为冷凝液，冷凝液又在热管节能模块作用下流至蒸发器吸收热量，整个系统通过热管节能模块将室内热量向室外传递。 In this way, this multi-stage heat pipe heat pump composite system can selectively operate the multi-stage heat pump cooling mode or the multi-stage heat pipe cooling mode according to the difference between the indoor required set temperature and the outdoor temperature, and can avoid "big horses" as needed. In the case of small cars”, choose to make some units in heat pump cooling mode or heat pipe cooling mode replace intermittent work, and achieve energy-saving operation under the premise of ensuring indoor cooling requirements; when the outdoor temperature is high or the indoor load is too large, The multi-stage heat pipe heat pump composite system operates in the heat pump refrigeration mode. The working principle is the same as that of general inverter or non-inverter air conditioners. The heat in the room is dissipated to the outdoor space through the vapor compression refrigeration cycle to achieve the cooling effect of the indoor space; When the temperature reaches a certain value, the compressor unit is turned off, and the unit automatically enters the heat pipe cooling mode. The gaseous refrigerant is brought to the condenser by the heat pipe energy-saving module to condense and release heat, and finally becomes condensate, which then flows to evaporation under the action of the heat pipe energy-saving module. The heat absorber absorbs heat, and the whole system transmits the indoor heat to the outdoor through the heat pipe energy-saving module.
