Detailed description of the invention
Be included in the structure of the side-flow type parallel flow heat exchanger in equipment according to embodiments of the present invention with reference to Fig. 1 explanationMake. In Fig. 1, the upside of paper is equivalent to the upside of heat exchanger, and the downside of paper is equivalent to the downside of heat exchanger. Heat is handed overParallel operation 1 comprise setting spaced apart parallel in the horizontal direction a pair of rising main 2 and 3 and between house steward 2 and 3 hang downThe many horizontal flat tubes 4 that Nogata upwards arranges with preset space length. In the time that reality is installed in equipment by heat exchanger, heat exchangeDevice 1 is installed with various angles according to designing requirement. Therefore, " vertical direction " and " horizontal direction " in this manual should notStrict interpretation. They are appreciated that it is only the expression of direction.
Flat tube 4 is the elongated members of extruding formation by metal, and is provided with the system that cold-producing medium flows through in insideCryogen path 5. Because flat tube 4 is configured to extrude direction, (, the longitudinal direction of flat tube 4) is level, soIn refrigerant passage 5, flow of refrigerant direction is also level. The many cold-producing mediums that section configuration and cross-sectional area are mutually the sameOn the depth direction of path 5 in Fig. 1, configure, therefore the vertical cross section of flat tube 4 has the mouth organ sample shape shown in Fig. 2. RespectivelyRefrigerant passage 5 and house steward's 2 and 3 internal communication.
On the flat horizontal surface of flat tube 4, be provided with fin 6. In the present embodiment, corrugated fin is as fin6, plate radiating plate also can be used as fin 6. In the fin 6 of arranged perpendicular, establish in the outside of highest and lowest finBe equipped with side plate 10.
The metal that house steward 2 and 3, flat tube 4, fin 6 and side plate 10 all have a good thermal conductivity by such as aluminium etc. forms.By brazing or welding, flat tube 4 is fixed on house steward 2 and 3, and fin 6 is fixed on flat tube 4, and side plate 10 is fixed to looseOn backing 6.
Heat exchanger 1 is side-flow type, and refrigerant inlet/outlet 7 and 8 is arranged on house steward 3. In other words,House steward 3 is the house stewards that connect side at refrigerant pipe. In house steward 3 inside, spaced apart in vertical direction two dividing plate 9a are setAnd 9c, and in house steward 2 inside, the intermediate altitude place between dividing plate 9a and 9c arranges dividing plate 9b.
When heat exchanger 1 is during as condenser, cold-producing medium as shown in the solid arrow in Fig. 1 from top refrigerant inlet/Outlet 7 flows into. The cold-producing medium entering from refrigerant inlet/outlet 7 stoped by dividing plate 9a and via flat tube 4 to house steward 2Advance. This flowing of cold-producing medium represents by pointing to left piece shape arrow. The cold-producing medium entering in house steward 2 is stoped also by dividing plate 9bAdvance to house steward 3 via other flat tubes 4. This be the revolution for the first time of cold-producing medium and after this revolution the flowing of cold-producing mediumRepresent by pointing to right piece shape arrow. Enter that cold-producing medium in house steward 3 is stoped by dividing plate 9c and via other flat tubes 4 again to alwaysPipe 2 advances. This be the revolution for the second time of cold-producing medium and after this revolution the flowing by pointing to left piece shape arrow of cold-producing mediumRepresent. The cold-producing medium entering in house steward 2 turns back and advances to house steward 3 via other flat tubes 4 again. This be cold-producing medium for the third timeRevolution and after this revolution flowing of cold-producing medium represent by pointing to right piece shape arrow. Cold-producing medium finally enters from cold-producing mediumMouth/outlet 8 flows out.
As mentioned above, cold-producing medium repeats revolution and flows from top to bottom via zigzag route. Here dividing plate has been described,Quantity is three situation. But this is only an example, the winding number that the quantity of dividing plate and the setting quantity by dividing plate provide mustWhile wanting, can be set as Arbitrary Digit.
In the formation of Fig. 1, be arranged in the many flat tubes 4 formation set streams higher than the height region of dividing plate 9a, positionMany flat tubes in height region between dividing plate 9a and dividing plate 9b 4 form another set stream, be positioned at dividing plate 9b andMany flat tubes 4 in height region between dividing plate 9c form another set stream, and are positioned at the height lower than dividing plate 9cMany flat tubes 4 in degree region form another set stream. These set streams normally bright order are called as respectively " theOne stream ", " the second stream ", " the 3rd stream " and " the 4th stream ".
In the time that heat exchanger 1 is used as evaporimeter, the mobile of cold-producing medium becomes on the contrary. That is to say, cold-producing medium is from Fig. 1Refrigerant inlet/outlet 8 shown in dotted arrow enters house steward 3, and by dividing plate, 9c stops, then via the 4th stream to house steward2 advance, and are stoped by the dividing plate 9b in house steward 2, then advance to house steward 3 via the 3rd stream, and by the dividing plate 9a in house steward 3Stop, then advance to house steward 2 again via the second stream, and in house steward 2, turn back with via the first stream again before house steward 3Enter, and by flowing out from refrigerant inlet/outlet 7 shown in dotted arrow.
In the time that heat exchanger 1 is used as condenser, the first stream is the stream before revolution for the first time, and the 4th stream isStream after revolution the last time. In the time that heat exchanger 1 is used as evaporimeter, the 4th stream is before revolution for the first timeStream, and the first stream is to turn round the last time stream afterwards.
In order to measure the temperature at the cold-producing medium of heat exchanger 1 internal flow, be provided with by electro-hot regulator is sealedThe temperature-sensitive element 11 forming in can. Temperature-sensitive element 11 is arranged on that cold-producing medium under gas-liquid two-phase state flows thereinIn at least one of flat tube 4, or be arranged between the flat tube 4 that the cold-producing medium that is clipped under gas-liquid two-phase state flows thereinFin on. Due to following former thereby select these positions.
In the time that heat exchanger 1 is used as condenser, cold-producing medium enters with superheat state from top refrigerant inlet/outlet 7,And this state is gas phase at this moment. After this,, when carry out heat exchange in the first stream time, cold-producing medium becomes gas-liquid two-phase stateCold-producing medium and condensation gradually. Near the outlet of the 4th stream flowing out at cold-producing medium, cold-producing medium in sub-cooled state alsoAnd be liquid. The temperature (two-phase temperature) of the cold-producing medium under gas-liquid two-phase state can be considered to condensation of refrigerant temperature or systemCryogen evaporating temperature, and be suitable for use as control fiducial temperature. Therefore, temperature-sensitive element 11 must be arranged on and can measure two-phase temperatureThe position of degree.
When heat exchanger 1 is during as evaporimeter, cold-producing medium from bottom refrigerant inlet/outlet 8 with gas-liquid two-phase stateEnter. After this, under gas-liquid two-phase state, carry out heat exchange and cold-producing medium evaporates gradually. The first stream flowing out at cold-producing mediumOutlet near, cold-producing medium is in gas-liquid two-phase state or in gaseous state. The temperature of the cold-producing medium under gas-liquid two-phase stateDegree (two-phase temperature) can be considered to cold-producing medium evaporating temperature, and is suitable for use as control fiducial temperature. Therefore, mustTemperature-sensitive element 11 is arranged on the position that can measure two-phase temperature.
As the position of measuring two-phase temperature, house steward 2 and 3 is also position candidate. But, in house steward 2 and 3, at someUnder operating condition, needn't obtain gas-liquid two-phase state.
Some side-flow type parallel flow heat exchangers have the rotating formation of the cold-producing medium of setting. In this formation, oneHouse steward is in superheat state, and another house steward is in sub-cooled state, therefore can not locate to measure gas-liquid two-phase house stewardTemperature under state.
In the situation that winding number is one, refrigerant inlet pipe is connected with one of them house steward with refrigerant outlet pipe. AlwaysThe refrigerant inlet side of pipe is full of the cold-producing medium of superheat state, and house steward's refrigerant outlet side is full of the system of sub-cooled stateCryogen does not therefore have the cold-producing medium of gas-liquid two-phase state where in house steward. In this case, also can not be alwaysThe temperature under gas-liquid two-phase state is measured at pipe place.
About flat tube 4, some in them always form the stream of the cold-producing medium under gas-liquid two-phase state. Therefore, logicalCross on these flat tubes 4 or be clipped on the fin 6 between these flat tubes 4 temperature-sensitive element 11 is set, can really surveyThe temperature of the cold-producing medium of the gas-liquid two-phase state current downflow in the various states of amount mobile cold-producing medium in heat exchanger 1, because ofThis, can infer exactly the pressure of cold-producing medium mobile in heat exchanger 1 and can really control various functions. At skyThe abnormality detection of tune equipment run duration also becomes easy.
As according in the heat exchanger 1 of embodiment, be configured to form plural system at many flat tubes 4In the rotating situation of cryogen, after being formed in the flat tube 4 of the stream before turning round for the first time and being formed in last revolutionThe flat tube 4 of stream outside flat tube 4 be considered to the flat tube that the cold-producing medium under gas-liquid two-phase state flows therein4. Accordingly, can easily select the setting position of temperature-sensitive element 11.
In the case of according to the heat exchanger 1 of embodiment, form the flat tube 4 of the first stream and form the 4th streamFlat tube 4 can be considered to be in respectively for the first time stream before revolution and revolution stream afterwards the last time. CauseThis, temperature-sensitive element 11 is not arranged on there. Form flat tube 4 and the folder of all the other streams (that is to say, second and the 3rd stream)Fin 6 between formation second and the flat tube 4 of the 3rd stream becomes the setting position of temperature-sensitive element 11.
When on the flat tube 4 at formation second or the 3rd stream or at the flat tube 4 that is clipped in formation second or the 3rd streamBetween fin 6 on when temperature-sensitive element 11 is set, advantageously in distance each house steward 2 and 3 equidistant position substantiallyTemperature-sensitive element 11 is set. In this position, cold-producing medium is unlikely subject to the impact of house steward 2 and 3 internal state, and can be certainMeasure the temperature at the cold-producing medium of gas-liquid two-phase state current downflow.
