Describe according to the parallel-flow heat exchanger 100 of the utility model embodiment below with reference to Fig. 1, can be used as outdoor unit heat exchanger according to the parallel-flow heat exchanger 100 of the utility model embodiment uses, certainly the utility model is not limited to this, and this parallel-flow heat exchanger 100 can also use as indoor set heat exchanger.In other words, this parallel-flow heat exchanger 100 can be used as condenser cold-producing medium is carried out to condensation, also can be used as evaporimeter cold-producing medium is evaporated.
As described in Figure 1, comprise according to the parallel-flow heat exchanger 100 of the utility model embodiment: the first header 1, the first pipe 2, the second pipe 3, the second header 4, multiple flat tube 5 and allocation component 6.
In the first header 1, be separated into two isolated the first upper chamber 111 and the first lower chambers 112 by the first dividing plate 11, " the first upper chamber 111 and the first lower chambers 112 are spaced apart " refers between the first upper chamber 111 and the first lower chambers 112 and is not communicated with.The first pipe 2 is communicated with the first upper chamber 111, and the second pipe 3 and the first lower chambers 112 are communicated with, and wherein the first pipe 2 and second manages 3 respectively as input pipe or the efferent duct of cold-producing medium.
The second header 4 and the first header 1 be arranged in parallel, alternatively, in parallel-flow heat exchanger 100 is installed to refrigeration plant time, the first header 1 and the second header 4 can extend along the vertical direction, install along left and right directions positioned at intervals, and example is direction as shown in Figure 1.Wherein, in the second header 4, be separated into multiple sub-chamber 41 by multiple partition components, multiple sub-chamber 41, by being formed on the channel connection on partition component, that is to say, cold-producing medium can mutually flow, mix in multiple sub-chamber 41.
In the example depicted in fig. 1, partition component is second partition 71, wherein passage is the bulkhead through-hole 711 being formed on second partition 71, that is to say, multiple sub-chamber 41 are interconnected by the bulkhead through-hole 711 on second partition 71 respectively, and cold-producing medium can and then enter in adjacent sub-chamber 41 through the bulkhead through-hole 711 on second partition 71.
Multiple flat tubes 5 are connected to abreast between the first header 1 and the second header 4 and respectively and are communicated with the first header 1 and the second header 4.The opposite face of the first header 1 and the second header 4 is outputed flat tube groove one to one, the left end of flat tube 5 inserts in the flat tube groove of the first header 1, the right-hand member of flat tube 5 inserts in the flat tube groove of the second header 4, fin (scheming not shown) is set between adjacent flat tube 5, the two ends of the first header 1 and the second header 4 are provided with blanking cover 42, to play sealing function.
Here it should be explained that, when parallel-flow heat exchanger 100 is during as condenser, because of cold-producing medium pressure ratio of cold-producing medium when the condensation higher, in the time of the Sizes of the bulkhead through-hole 711 of second partition 71, the proportion that the pressure drop that cold-producing medium produces by bulkhead through-hole 711 accounts for whole condensation of refrigerant pressure is very little, and the volume of unit mass cold-producing medium can shrink when condensation, therefore cold-producing medium limit condensation side is by not too large problem of bulkhead through-hole 711, but in the time that parallel-flow heat exchanger 100 is used as evaporimeter, there is variation in its situation, in the time that cold-producing medium evaporates, cold-producing medium in the second header 4 is gas-liquid two-phase state, the cold-producing medium of the second header 4 will be in reasonable distribution of the interior work of each sub-chamber 41 obviously, but when evaporation cold-producing medium much lower during compared with condensation of pressure, therefore cold-producing medium has gas-liquid layering at the second header 4, because fluid density is larger than gas, therefore the lower liquid of the second header 4 is many, upper liquid is few, thereby cause the cold-producing medium in superposed sub-chamber 41 to distribute unbalanced, and adjust the cold-producing medium sendout in corresponding sub-chamber 41 by the size of adjusting the bulkhead through-hole 711 on second partition 71, also the refrigerant amount that is only applicable to sub-chamber's 41 demands on top is less than the situation of the sub-chamber 41 of bottom, and the refrigerant amount of sub-chamber's 41 demands on top is greater than the situation of bottom sub-chamber 41, be just difficult to reach.
Inventor of the present utility model has just proposed, on the second header 4, allocation component 6 is set and has solved this problem thus, particularly, as shown in Figure 1, allocation component 6 comprises entrance pipe 62 and at least one export pipeline 63 of having the distributor disk 61 of distribution cavity and be communicated with distribution cavity respectively, entrance pipe 62 with in multiple sub-chamber 41, be positioned at the sub-chamber 41 of below and be communicated with, at least one export pipeline 63 is communicated with all the other sub-chamber 41 respectively.That is to say, entrance pipe 62 is identical with the quantity of sub-chamber 41 with the quantity sum of export pipeline 63 and corresponding one by one, and for example sub-chamber 41 comprises two, and export pipeline 63 comprises one; For example sub-chamber 41 comprises three, export pipeline 63 comprise two and two export pipelines 63 respectively be positioned at the top and middle sub-chamber 41 and be communicated with; In example example as shown in Figure 1, partition component comprises three, three partition components will be separated into four sub-chamber 41 in the second header 4, the export pipeline 63 of allocation component 6 is three, and three export pipelines 63 are removed its excess-three sub-chamber 41 of the sub-chamber 41 of below in corresponding four sub-chamber 41 respectively; For example partition component comprises four again, four partition components will be separated into five sub-chamber 41 in the second header 4, the export pipeline 63 of allocation component 6 is four, and four export pipelines 63 are removed all the other four sub-chamber 41 of the sub-chamber 41 of below in corresponding five sub-chamber 41 respectively.Wherein, above-mentioned example all can effectively be distributed the cold-producing medium entering in the second header 4, avoids refrigerant air-liquid layering too serious, improves heat transfer effect.
Alternatively, the second header 4 below the bottom sides of sub-chamber 41 have a hole, entrance pipe 62 is inserted in the sub-chamber 41 of below by this hole, the other end of entrance pipe 62 is communicated with the distribution cavity in distributor disk 61.In example as shown in Figure 1, one end of three export pipelines 63 can be inserted in corresponding sub-chamber 41 by the hole on corresponding sub-chamber 41 upper side walls respectively, and the other end of three export pipelines 63 is all communicated with the distribution cavity in distributor disk 61.
Advantageously, in multiple partition components, being positioned at partition component and first dividing plate 11 of below is positioned on same level height, the flat tube 5 being communicated with the first lower chambers 112 so is also only communicated with the sub-chamber 41 of below that is positioned at of the second header 4 simultaneously, can make like this structure of parallel-flow heat exchanger 100 more reasonable, the utilization rate of flat tube 5 is the highest, does not have flat tube 5 by short circuit (be cold-producing medium can flow through all flat tubes 5).
Below with reference to Fig. 1, the flow direction of the cold-producing medium while describing parallel-flow heat exchanger 100 respectively as condenser and evaporimeter.
When parallel-flow heat exchanger 100 is during as condenser, its refrigerant flow direction is as shown in the filled arrows in Fig. 1, the cold-producing medium of HTHP enters from the first pipe 2 in the first upper chamber 111 of the first header 1, then be assigned in the flat tube 5 being communicated with the first upper chamber 111 and carry out condensation, cold-producing medium enters in the sub-chamber 41 of the second header 4 out from flat tube 5, by the aperture of rational bulkhead through-hole 711 is set, can ensure that most of cold-producing mediums pass through and enter from the bulkhead through-hole 711 of second partition 71 puts in place in the sub-chamber 41 of below, then cold-producing medium is redistributed to this flat tube 5 that sub-chamber 41 of below is connected and continues condensation.After condensation completes, cold-producing medium collects in the first lower chambers 112 of the first header 1, flows out finally by the second pipe 3.
When parallel-flow heat exchanger 100 is during as evaporimeter, its refrigerant flow direction is as shown in the hollow arrow in Fig. 1, the cold-producing medium of low-pressure gas-liquid two-phase is entered by the second pipe 3 in the first lower chambers 112 of the first header 1, then cold-producing medium is assigned in the flat tube 5 being connected with the first lower chambers 112 and evaporates, flow through after corresponding flat tube 5, cold-producing medium has evaporated the sub-chamber 41 of below that is arranged in that enters into again the second header 4 after a part, the cold-producing medium that is now arranged in the sub-chamber 41 of below can layering, the liquid refrigerant major part that density is larger is sunken to the bottom of this sub-chamber 41, therefore liquid refrigerant can flow into from the entrance pipe of allocation component 6 62, and in distributor disk 61, be assigned in each export pipeline 63, enter into respectively the corresponding sub-chamber 41 of the second header 4 through the guiding of corresponding export pipeline 63, cold-producing medium in corresponding sub-chamber 41 flows into respectively in the flat tube 5 being communicated with each sub-chamber 41, in corresponding flat tube 5, each road cold-producing medium continues flow and evaporate, until cold-producing medium collects in the first upper chamber 111 of the first header 1, flow out parallel-flow heat exchanger 100 finally by the first pipe 2.
By finding out in description above, according to the parallel-flow heat exchanger 100 of the utility model embodiment, kind of refrigeration cycle and what heat that circulating refrigerant sidles at the second header 4 is different passages, especially when parallel-flow heat exchanger 100 is during as evaporimeter, cold-producing medium can distribute by allocation component 6, avoid the too serious of refrigerant air-liquid layering in superposed flat tube 5, by adjusting length or the internal diameter of export pipeline 63, make evaporation process be tending towards optimum, the final refrigerant air-liquid layering and the maldistribution phenomenon that heat circulation of substantially having solved, greatly improve the heat exchange efficiency of parallel-flow heat exchanger 100 under different mode.
To sum up, by allocation component 6 is set, can effectively solves cold-producing medium and distribute uneven problem, improve the heat exchange efficiency of parallel-flow heat exchanger 100, and the reliable in structure of allocation component 6, therefore can be applicable to produce in enormous quantities.
According to the parallel-flow heat exchanger 100 of the utility model embodiment, owing to being formed with bulkhead through-hole 711 on the second partition 71 in the second header 4, each sub-chamber 41 is communicated with by bulkhead through-hole 711, like this in the time of outlet assignment system cryogen, between adjacent sub-chamber 41, have a small amount of cold-producing medium and exchange by bulkhead through-hole 711, therefore this parallel-flow heat exchanger 100 also can be subject to a certain extent the impact of bulkhead through-hole 711 in the time carrying out evaporimeter.
Inventor of the present utility model further improves partition component thus, describes according to the partition component of the different embodiment of the utility model below with reference to Fig. 2-Fig. 6.
As shown in Fig. 2-Fig. 6, can also be device in one-way on state 72 according to the partition component of the present embodiment, that is to say, above-mentioned second partition 71 can be replaced by device in one-way on state 72.Device in one-way on state 72 is configured to one-way conduction from top to bottom, the wherein direction of above-below direction for indicating in Fig. 1, and this device in one-way on state 72 can allow cold-producing medium to flow from the top down, and stops cold-producing medium to flow from bottom to top.Like this when parallel-flow heat exchanger 100 is during as condenser, in the second header 4 cold-producing medium can by device in one-way on state 72 from above the sub-chamber 41 of sub-chamber 41 below flowing to; When parallel-flow heat exchanger 100 is during as evaporimeter, cold-producing medium flows from bottom to top in the second header 4, due to device in one-way on state 72 stop cold-producing medium from bottom to top flow, therefore the cold-producing medium in the second header 4 is cut off by device in one-way on state 72 and can not in each sub-chamber 41, circulate, now just can only by allocation component 6, cold-producing medium be assigned in each sub-chamber 41 to the impact that can avoid thus the bulkhead through-hole 711 of second partition 71 as shown in Figure 1 to distribute cold-producing medium.
In an embodiment of the present utility model, as shown in Fig. 2-Fig. 3, device in one-way on state 72 comprises: cylindrical shell 721 and partition 722, cylindrical shell 721 is adapted to fit in the second header 4, the external diameter of cylindrical shell 721 preferably equals or is slightly smaller than the internal diameter of the second header 4, so that cylindrical shell 721 can be located in the second header 4 stably, easily.Wherein, the lower end of cylindrical shell 721 is opened wide and upper end has apical pore 7211, and apical pore 7211 runs through the roof of cylindrical shell 721, and partition 722 is located in cylindrical shell 721 movably, and the external diameter of partition 722 is slightly smaller than the internal diameter of cylindrical shell 721.Wherein, partition 722 is configured in the time of the 721 upper ends laminating of itself and cylindrical shell shutoff apical pore 7211 and in the time that it departs from cylindrical shell 721 upper end, is positioned at the liquid of partition 722 tops can be by its discharge cylindrical shell 721 downwards, that is to say, when the roof laminating of partition 722 and cylindrical shell 721 shutoff apical pore 7211 and in the time that it departs from the roof of cylindrical shell 721, be positioned at the liquid of partition 722 tops can be by its discharge cylindrical shell 721 downwards.
Thus, device in one-way on state 72 is installed to the second header 4 when interior, in the time that cold-producing medium flows from top to bottom, can enter in cylindrical shell 721 by apical pore 7211, due to the flowing pressure of cold-producing medium, partition 722 is pulled to the bottom of cylindrical shell 721, and now partition 722 can flow out for cold-producing medium, thereby cold-producing medium can be discharged cylindrical shell 721, can utilize like this device in one-way on state 72 to be communicated with adjacent sub-chamber 41; In the time that cold-producing medium flows from bottom to top, first partition 722 moves up under the flowing pressure effect of cold-producing medium, in the time that partition 722 is pulled to the top of cylindrical shell 721, partition 722 is just by apical pore 7211 shutoff, and now cold-producing medium can not enter in adjacent sub-chamber 41 by cylindrical shell 721.To sum up, at parallel-flow heat exchanger 100, during as condenser, device in one-way on state 72 can be communicated with adjacent sub-chamber 41; At parallel-flow heat exchanger 100, during as evaporimeter, device in one-way on state 72 can the adjacent sub-chamber 41 of shutoff.The height of its middle cylinder body 721 is less than 30mm, due to the structural limitations of the second header 4, by the height of cylindrical shell 721 being controlled in the scope that is less than 30mm, can not produce too much interference thereby can cylindrical shell 721 be located at the second header 4 after interior, thereby can make the structure of the second header 4 that is provided with cylindrical shell 721 unaffected.
In a concrete example of the present utility model, as shown in Figure 2, on partition 722, there are multiple partition holes 7221 of running through it, projection and the multiple partitions hole 7221 of apical pore 7211 on partition 722 is all spaced apart, be that apical pore 7211 can not overlap with partition hole 7221, when partition 722 moves to while contacting with the roof of cylindrical shell 721, partition 722 will block apical pore 7211, to stop cold-producing medium to pass through like this.In the time that partition 722 moves to the bottom of cylindrical shell 721, due to the bottom-open of cylindrical shell 721, partition hole 7221 can not blocked completely, and therefore cold-producing medium can enter, flow out cylindrical shell 721 by apical pore 7211 and partition hole 7221 respectively.Preferably, multiple partitions hole 7221 is close to the edge setting of partitions 722 and is uniformly distributed circumferentially, and makes thus the simple in structure and reasonable of partition 722.In an example of the present utility model, partition hole 7221 is four.
In another concrete example of the present utility model, the example shown in as shown in Figure 3, different from the example shown in Fig. 2, on the edge of partition 722, there is at least one groove 7222 inwardly concaving.In projection on above-below direction, groove 7222 does not overlap with apical pore 7211, limits the through hole for flow of refrigerant between groove 7222 and the inwall of cylindrical shell 721.Alternatively, groove 7222 is formed as square groove, dovetail groove or deep-slotted chip breaker, can make like this shape of groove 7222 more diversified, and groove 7222 can adapt to the use of more industrial situations.Alternatively, groove 7222 is 3-8.
