The computer room end fin-tube heat exchanger of the utility model can be introduced directly into the chilled water that outdoor cold provides and make For working media, need to increase relief valve as circulation power, but in system pipeline using the water pump in outdoor cold water system, together When pay attention to water quality situation, periodical blowdown, to avoid heat exchanger because system working pressure is excessive or corrosion of piping, it is dirty it is stifled caused by manage Road explosion.
The computer room end fin-tube heat exchanger of the utility model can also be by cold outside Intermediate Heat Exchanger indirect utilization room The chilled water that machine provides need to increase water pump at this time between the heat exchanger and Intermediate Heat Exchanger to mention needed for watering cycle Power.
The computer room end of the utility model with fin-tube heat exchanger can independent 1 use in the unit or 2 simultaneously It uses in the unit.When 2 use in the unit simultaneously and unit water route is single-entry single-out, 2 heat exchangers it is described Inlet header interface can be inputted using with water all the way, and the outlet header interface of 2 heat exchangers can use same The output of road water, but the exhaust valve of 2 heat exchangers and the drain valve cannot omit.
Preferably, the export pipeline of the inlet ductwork of the inlet header and the outlet header is close to the bottom of collector Portion's setting.At this point, into lower mode out under the water route use of the heat exchanger.
Preferably, after the heat exchanger is drained by the drain valve, the exhaust valve and drain valve conduct simultaneously Pressure-air blow valve port further purges the inner tube of heat exchanger road, is dried, to prevent chilled water draining from not emptying, Heat exchanger tube bursting by freezing problem.
Compared with the existing technology, the computer room end fin-tube heat exchanger of the utility model, inlet header and outlet There are exhaust valve and drain valve on collector respectively.The computer room end fin-tube heat exchanger of the utility model, can be direct or indirect The chilled water provided using outdoor cold is directly as working media, heat exchanger applications end prod between chilled water column at this time On, heat transfer efficiency is high, and energy-saving effect is good;Or refrigeration working medium is used as using freon R22, R134a, R410a etc., heat exchanger at this time Applied on product, safety coefficient is high, and heat-transfer effect is good between fluorine pump heat pipe column.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the computer room end fin-tube heat exchanger of the utility model.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, develop simultaneously implementation referring to the drawings The utility model is further described in example.
As shown in Figure 1, the computer room end fin-tube heat exchanger of the utility model, including the array cloth in short transverse The inlet header 5 that the multiple U-shaped heat exchanger tubes 1 set, the fins set 2, one being fixed on multiple U-shaped heat exchanger tubes 1 are arranged vertically The outlet header 6 arranged vertically with one, U-shaped heat exchanger tube 1 preferably use seamless copper tube, and fins set 2 preferably uses hydrophilic aluminium foil, Each U-shaped heat exchanger tube 1 includes two ports for being located at heat exchanger the same side, in each port of multiple U-shaped heat exchanger tubes 1, portion Port is divided to be connected to inlet header 5, section ports are connected to outlet header 6, remaining port is welded by nipple 1-2 It blocks, wherein the top of inlet header 5 is provided with exhaust valve 3, and the bottom of outlet header 6 is provided with drain valve 4, works as heat exchanger When having condensed water, it can ensure that condensed water smoothly flows therein in the drip tray of exchanger base.Exhaust valve and drain valve conduct simultaneously Pressure-air blow valve port, after being drained for heat exchanger by drain valve, pipeline is purged, is dried in further heat exchanging device, To prevent chilled water draining from not emptying, heat exchanger tube bursting by freezing problem.
Embodiment as a further preference, exhaust valve 3 are mounted on the top of inlet header 5 and are located at the highest of heat exchanger End;Drain valve 4 is mounted on the bottom of outlet header 6 and is located at the least significant end of heat exchanger.
As a kind of mode of preferred implementation, U-shaped heat exchanger tube 1 uses the pattern of long U pipe 1-1, and nipple 1-2 is equally adopted With the pattern of U pipe, long U pipe 1-1 is arranged in a manner of being parallel to ground, and fins set 2 is vertically fixed in a manner of conjunction of rising On long U pipe 1-1.
When carrying out water route arrangement, the water route of heat exchanger preferably use under into it is lower go out mode, i.e. the water inlet of inlet header 5 Mouthful, the water outlet of outlet header 6 be close to the bottom setting of collector.
When using the fin-tube heat exchanger of the utility model, heat exchanger can be provided directly or indirectly using outdoor cold Chilled water as working media, heat exchanger applications are between chilled water column on end prod at this time.When heat exchanger is introduced directly into room When the chilled water that outer cold provides is as working media, using the water pump in outdoor cold water system as circulation power, but it is Lu Zhongxu under the overall leadership increases relief valve, while paying attention to water quality situation, periodical blowdown, to avoid heat exchanger because system working pressure is excessive Or corrosion of piping, dirty stifled caused pipelines from bursting.When heat exchanger provided by cold outside Intermediate Heat Exchanger indirect utilization room it is cold When freezing water, at this time between heat exchanger and Intermediate Heat Exchanger, water pump need to be increased with power needed for mentioning watering cycle.
In addition, freon R22, R134a, R410a etc. also can be used as refrigeration working medium in heat exchanger, heat exchanger applications at this time Between fluorine pump heat pipe column on product, need to be equipped with fluorine pump on the inlet header 5 of heat exchanger as driving force.
The fin-tube heat exchanger heat exchanger of the utility model can independent 1 use in the unit, can also 2 simultaneously exist It is used in unit.When 2 use in the unit simultaneously and unit water route is single-entry single-out, the interfaces of 2 inlet headers 5 can be with It is inputted using with water all the way, 26 interfaces of outlet header can be exported using with water all the way, but 2 exhaust valves and drain valve are not It can omit.
When using the fin-tube heat exchanger of the utility model, impurities in water is walked clearly in time to ensure, avoids heat exchanger It is dirty stifled, installation filter is needed on the inlet pipeline of inlet header 5.In addition, being regulating water flow to meet load variation It is required that the settable electric two-way valve on the export pipeline of outlet header 6.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent substitution, improvement and etc. done should be included in the utility model protection Within the scope of.
