In the refrigerator 1, as shown in Fig. 2, the space between outer container 2 and interior case 3 is provided with vacuum heat insulation material 6. Though detailed description has been omitted from, vacuum heat insulation material 6 is using film coated core material, and the inside to cladding is depressurized Play the heat insulating component of high heat-proof quality.Though diagram has been omitted from, the vacuum heat insulation material 6 passes through bonding agent or double faced adhesive tape Deng and be adhered to the inner surface of outer container 2.Moreover, being provided with the shallow slot that aftermentioned heat-dissipating pipe 10 is arranged in vacuum heat insulation material 6 Portion 6a.

Moreover, being filled with foaming heat insulation material in the space other than vacuum heat insulation material 6 between outer container 2 and interior case 3 Material 16 (referring to Fig. 5).Furthermore in Fig. 2, the left and right, the back side, bottom for being configured at interior case 3 are illustrated only to simplify the explanation Vacuum heat insulation material 6, but can also top plate side be arranged vacuum heat insulation material 6.Moreover, for example can also be for not in the wall portion of left and right Side filling-foam heat-barrier material 16 and the composition etc. that vacuum heat insulation material 6 is only set.

As shown in Figure 1, being configured with compressor 7 in lower mechanical room 4.Pressure is connected to moreover, being configured in top Machine Room 5 The condenser 8 of contracting machine 7, with cooling fan 9 is carried out to condenser 8.Pass through the compressor 7, condenser 8 and (not shown) Evaporator etc. constitutes so-called refrigerating cycle.Furthermore in lower mechanical room 4 and top Machine Room 5, it is also configured with compressor 7 with condenser 8 other than mechanical component etc..

As shown in figure 3, condenser 8 includes: two collectors 11 of hollow cylindrical；More flat tubes 12, by each collector It is connected between 11；Fin 13, by being formed in the metal material etc. being hummock set between flat tube 12；And connection Pipe 14, is respectively arranged at each collector 11, and the condenser 8 is shaped generally as the rectangular-shape of slim body.Each flat tube 12 divides A plurality of refrigerant flow is not formed in inside.

Condenser 8 makes refrigerant in the inside of each flat tube 12, is in from refrigerant flow process shown in arrow F respectively The collector 11 of the entrance of the diagram left side of upstream side, diagram right side of the flow direction in refrigerant flow process in downstream side The collector 11 of outlet.That is, condenser 8 is the multi-streaming type condenser of so-called run-in index.In the present embodiment, pass through axial flow type Fan 9 promote the condenser 8 to radiate.At this point, fan 9 is configured substantially in parallel with the body part of condenser 8, that is, It is configured in such a way that the wind efficiency for conveying fan 9 is blown to body part well.

As shown in Figure 1, heat-dissipating pipe 10 is connected to entrance and the outlet of condenser 8.Furthermore though the illustration is omitted in Fig. 1, But heat-dissipating pipe 10 is connected via connecting tube 14.Moreover, the setting position or its path of heat-dissipating pipe 10 are not limited to Fig. 1 institute The setting position shown or path.

As shown in figure 4, the shape of the heat-dissipating pipe 10 is formed as flat, and multiple hollow portions are formed in inside 10a, refrigerant flow in the hollow portion 10a.That is, heat-dissipating pipe 10 becomes the construction similar with the flat tube 12 of condenser 8.Again Person, the quantity or shape for being set to the hollow portion 10a of heat-dissipating pipe 10 are not limited to quantity or shape shown in Fig. 4.Such as Fig. 5 institute Show, the heat-dissipating pipe 10 is contained in the groove portion 6a of vacuum heat insulation material 6 with being connected to the state of the inner surface of outer container 2.

Moreover, condenser 8 includes a plurality of refrigerant flow in flat tube 12 in the case where refrigerator 1 of such composition, because This, compared with the condenser of previous 13 cast of fin for being provided with a refrigerant flow, internal flow refrigerant with it is flat Contact area between flat pipe 12 increases.The result is that the heat meeting efficiency of refrigerant is transferred to flat tube 12 well.Moreover, by metal The fin 13 that material is formed is set to each flat tube 12 with contact condition, and therefore, the heat meeting efficiency of flat tube 12 is transmitted well To fin 13.

Moreover, the fin 13 for being set to condenser 8 is in hummock to be formed between flat tube 12, therefore, surface area is big, energy The wind efficiency enough conveyed by fan 9 is radiated i.e. heat exchange well.Therefore, the condenser 8 of multi-streaming type can imitate Rate will be transferred to fin 13 in the heat of the refrigerant of internal flow well, efficiently use high surface area to discharge the heat, therefore, Compared with the condenser of previous 13 cast of fin, radiating efficiency is improved.

Therefore, if keeping heat dissipation capacity identical as previous 13 cast of fin, condenser 8 can be made to minimize.That is, can make Space needed for accommodating condenser 8 is reduced, and in other words, storeroom can be made enlarged.

Moreover, the surface area that can be used in heat dissipation of condenser 8 is big, therefore, even if the fan 9 relatively low for air quantity, i.e., More small-sized fan 9, can also obtain high cooling efficiency.Thus, it is also possible to minimize fan 9.That is, heat dissipation performance improves, Thereby, it is possible to reduce the consumed electric power that radiates, so as to realize energy conservation.

Condenser 8 is set to the top plate side of refrigerator 1 and the top Machine Room 5 of back side.The top plate side of refrigerator 1 and back side Though also depending on the size of refrigerator 1, it is difficult to the position touched for the hand of user, and easily becomes idle space (dead space).Therefore, by the way that top Machine Room 5 to be set to top plate side and the back side of refrigerator 1, and condenser 8 is configured at institute Top Machine Room 5 is stated, idle space effectively can be flexibly used.

Moreover, the space of lower mechanical room 4 can be saved by the way that condenser 8 is configured at top Machine Room 5, so as to Enough minimize lower mechanical room 4.Thereby, it is possible to make to be set to 4 front of lower mechanical room in storeroom i.e. present embodiment Freezing chamber enlargement.

Moreover, the shape of heat-dissipating pipe 10 is formed as flat, therefore, compared with cylindric heat-dissipating pipe, with outer container 2 The contact area of inner surface contact increases, and the depth of groove portion 6a also reduces.Thereby, it is possible to reduce vacuum heat insulation material 6 Intensity decline.

Moreover, because heat-dissipating pipe 10 is configured between outer container 2 and vacuum heat insulation material 6, so can reduce for storage Hide the heat leak (heat leak) of room.

Moreover, for heat-dissipating pipe 10, since the heat dissipation performance of condenser 8 is high, so it is compared with the past compared with can contract Short required length.Therefore, Costco Wholesale can not only be reduced, and operating cost when manufacture can be reduced.

Moreover, heat-dissipating pipe 10 is to be disposed in the space between outer container 2 and interior case 3 along the inner surface of outer container 2, and connect Compressor 7 and condenser 8.The relatively high refrigerant of temperature is flowed in the inner side surface of refrigerator 1 as a result, and thus, it is possible to utilize temperature To make the surface of refrigerator 1 warm.That is, anti-dew can be used for the heat that condenser 8 is discharged, so as to inhibit in refrigerator 1 Surface condenses.

In this way, according to refrigerator 1, due to that Machine Room can be made to minimize, so can be enlarged with storeroom, and pass through The heat dissipation for improving heat-dissipating pipe 10, can be realized energy conservation, the refrigerator 1 includes: outer container 2；Interior case 3 keeps empty between outer container 2 Between configure；The condenser 8 of multi-streaming type comprising be formed with the flat tube 12 for a plurality of flow path that refrigerant is flowed through；And heat dissipation Pipe 10 is connected to condenser 8, and being formed as inside includes the flat of multiple hollow portion 10a as refrigerant flow.

(the 2nd embodiment)

Hereinafter, referring to Fig. 6 to Figure 19, the 2nd embodiment is illustrated.2nd embodiment is to the 1st embodiment institute The other shapes etc. of the condenser 8 shown are illustrated.

Condenser 8 is not limited to the condenser of multi-streaming type shown in the 1st embodiment, is able to use fin pipe as in the past The condenser of type.

Moreover, condenser 8 can use the condenser 8 of reentrant type, the condenser 8 of the reentrant type is as shown in fig. 6, entrance Same collector 11 is set to the connecting tube 14 of outlet.In said case, collector 11 is at being constructed as follows: in connecting tube Separating part is provided between 14, the refrigerant flowed into from the connecting tube 14 of the entrance in diagram upper side is in another collector 11 It turns back, is flowed out from the connecting tube 14 of the outlet in diagram lower side.Even if in the feelings for the condenser 8 for using such reentrant type Under condition, the heat dissipation performance of condenser 8 also can be improved, therefore, in a same manner as in the first embodiment, Machine Room can be made to minimize, And by the heat dissipation for improving heat-dissipating pipe 10, it can be realized energy conservation.

Moreover, can using the condenser 8 for formula of wriggling, the condenser 8 of the sinuous formula as shown in fig. 7, make one it is flat Pipe 12 wriggles and connects entrance and outlet.It in said case, can be as shown in fig. 7, collector 11 be set to substantially rectangular parallelepiped Body part same avris, can also be as shown in figure 8, collector 11 to be set to the diagonal side of the body part of substantially rectangular parallelepiped. Even if also can be improved the heat dissipation performance of condenser 8 in the case where using condenser 8 of such sinuous formula, therefore, with the 1 embodiment similarly, can be such that Machine Room minimizes, and the heat dissipation by improving heat-dissipating pipe 10, can be realized energy conservation.

Moreover, as shown in figure 9, the condenser 8 of run-in index can be used, the condenser 8 of the run-in index is for example obliquely The collector 11 of entrance side is formed, and changes the length of each flat tube 12, as a result, being integrally formed into substantially comprising skewed side The shape of trapezoidal shape.Moreover, as shown in Figure 10, can use the condenser 8 of reentrant type, the condenser 8 of the reentrant type makes to locate Collector 11 in entrance side is separated with the collector 11 in outlet side, is formed as the shape of scale shape.Moreover, as shown in figure 11, Turning length (the tum that change flat tube 12 can be passed through using the condenser 8 for formula of wriggling, the condenser 8 of the sinuous formula Length) be formed as the shape of scale shape.

Moreover, as shown in figure 12, it can be using the condenser 8 for formula of wriggling, the condenser 8 of the sinuous formula is by gradually changing Become turning length and be formed as comprising skewed side generally trapezoidal shape shape.Moreover, condenser 8 is also capable of forming as packet Containing it is skewed while with scale shape while described in both shape, such as can also use the condenser of sinuous formula shown in Fig. 7 8, the condenser 8 of the sinuous formula is formed as following shape, that is, middle part is provided with recess portion in order to avoid piping etc..

In this way, using body part for the condenser 8 of the shape other than rectangle, become as a result, for example along lower mechanical room 4 Inclined-plane shape, therefore, the freedom degree of configuration improves, and effectively can flexibly use space.Extra space disappears as a result, It loses, can be realized the miniaturization i.e. enlargement of storeroom of Machine Room.

Moreover, as shown in figure 13, may be integrally formed flat tube 12 and the heat-dissipating pipe 10 in the condenser 8 of sinuous formula. That is, a part of heat-dissipating pipe 10 can also be used as to the condenser 8 for formula of wriggling by making heat-dissipating pipe 10 wriggle.According to such composition, Until the entrance to outlet of condenser 8, it is piped identical, that is, the shape of internal flow path is identical, can reduce the pressure loss. In said case, furthermore, as the 1st embodiment, it when connecting heat-dissipating pipe 10, can be improved system via connecting tube 14 The property made or workability.

Moreover, can also be as shown in figure 14, make 10 branch of heat-dissipating pipe.Thereby, it is possible to heat-dissipating pipe 10 is widely disposed in ice The inner side surface of case 1, so as to be radiated using the entire wall surface of refrigerator 1, it is contemplated that can be improved heat dissipation performance and mention High anti-dew performance.In said case, in the entrance side of gasiform condenser 8, make refrigerant branch, thereby, it is possible to not interfere Refrigerant flowing.Certainly, it is not limited to make 10 branch of heat-dissipating pipe in entrance side, 10 branch of heat-dissipating pipe of outlet side can also be connected to.

Moreover, 10 branch of heat-dissipating pipe can not be made, but as shown in figure 15, more heat-dissipating pipes 10 are connected to collector 11. According to such composition, heat-dissipating pipe 10 can be widely disposed in the inner side surface of refrigerator 1, also so as to utilize refrigerator 1 Entire wall surface radiates, it is contemplated that can be improved heat dissipation performance and improves anti-dew performance.This condenser 8 for run-in index It is identical.

Moreover, as shown in figure 18, it can be by heat-sinking capability compared with the smaller auxiliary of condenser 8 for being configured at top Machine Room 5 Condenser 20 is configured at lower mechanical room 4, and the entrance of connect compressor 7 and auxiliary condenser 20 connects auxiliary condenser 20 Outlet and a heat-dissipating pipe 10 connect the entrance of the heat-dissipating pipe 10 with condenser 8, and connect the outlet of condenser 8 with it is another Root heat-dissipating pipe 10.The higher refrigerant of temperature flowed out as a result, from compressor 7 with certain degree by auxiliary condenser 20 firstly, cooled down Later, the interior surface by heat-dissipating pipe 10 in refrigerator 1 flows.Therefore, it can reduce for storing indoor heat leak.And And therefore auxiliary condenser 20 can prevent lower mechanical room 4 from unnecessarily increasing for small condenser.

It can also be used following condenser 8, as shown in figure 17, including multiple such as two by symbol 8a table for the condenser 8 The body part shown.The condenser 8 is run-in index condenser, and flat tube 12 is along width direction by so-called curved along side It is bent.Moreover, condenser 8 before and after the bending part of flat tube 12, respectively includes the body part 8a with fin 13.Such In the case where condenser 8, with from the body part 8a of the relatively low outlet side of temperature (diagram lower side) to temperature it is relatively high enter The mode of the body part 8a air-supply of mouthful side (diagram upper side) configures fan 9, that is, so that the entrance side of refrigerant is located at by fan The mode in the downstream side in the 9 air-supply paths formed is configured, and thereby, it is possible to inhibit the decline of heat dissipation performance.

In the 1st embodiment, the example for configuring the fan 9 of axial-flow type substantially in parallel with condenser 8 is illustrated, but such as Shown in Figure 18, centrifugal fan 9 can be used.In the case where centrifugal fan 9, as shown by arrow B, from fan 9 to Circumferencial direction is diffusely blown.It is improved accordingly, with respect to the freedom degree of the allocation position of the condenser 8 of fan 9.Moreover, even if In the case where needing to configure multiple condenser 8, can also be blown using a fan 9 to multiple condensers 8.

Moreover, as shown in figure 19, body part is formed as to the curved such as arciform of the shape along fan 9, thereby, it is possible to The wind efficiently conveyed using fan 9.At this point, the body part of condenser 8 to be set as to the shape of the circumferencial direction along fan 9 Shape, thereby, it is possible to extend the length of body part, so as to relatively reduce height.Moreover, overlappingly configuring multiple centrifugal Fan 9, as a result, even for for example with Fig. 2 it is equal shown in height condenser 8, also can be to the entire surface of body part Air-supply.

In the 1st embodiment, the composition that heat-dissipating pipe 10 is contained in the groove portion 6a of vacuum heat insulation material 6 is illustrated, but Also it is capable of forming following construction, that is, groove portion 6a is set not in vacuum heat insulation material 6, but will by vacuum heat insulation material 6 Heat-dissipating pipe 10 is urged to the inner surface of outer container 2.As a result, it is not necessary that groove portion 6a is arranged in vacuum heat insulation material 6, can further subtract A possibility that small intensity declines.

(the 3rd embodiment)

Hereinafter, in the present specification, as shown in figure 20, refrigerator 101 will be configured it is rear in the state of along gravity Direction be known as up and down direction, the slave left plate 104 in the state of refrigerator 101 will be observed from the front towards the side of right side plate 105 To referred to as left and right directions, it is illustrated front-rear direction is known as towards the direction of 103 side of backboard from door 110a.

Lower part in ontology 102 is provided with Machine Room 108.Moreover, backboard 103, left plate 104, right side plate 105 and bottom Plate 107 is formed with the opening portion 109 being connected to in Machine Room 108 in the position for corresponding to Machine Room 108.Each opening portion 109 exists When cooling fan 120 (referring to Figure 21) actuation, as air being sucked into the air inlet in Machine Room 108 from outside or will be empty Gas is expelled to out of Machine Room 108 external exhaust outlet and is functioned.According to the position of the cooling fan 120 in Machine Room 108 It sets, determines that opening portion 109 is to function as air inlet, or function as exhaust outlet.Furthermore opening portion 109 can be simple slit, and it is louvered etc. for caning be processed, and may also set up dustproof filter screen etc..

As shown in figure 21, compressor 111, condenser 112, cooling fan 120 etc. are provided in Machine Room 108.It is described Compressor 111 and condenser 112 and evaporator (not shown) (evaporator) constitute refrigerating cycle 121 together.In the machine In tool room 108, it is also equipped with other groups other than compressor 111, condenser 112, cooling fan 120 that diagram is omitted Part.Moreover, certainly, control unit is also disposed in ontology 102, the control unit to include compressor 111, it is condenser 112, cooling The entirety of the refrigerator 101 of fan 120 etc. is controlled.Moreover, condenser 112 is connected to the 1st embodiment institute that diagram is omitted Heat-dissipating pipe 10 shown etc..

In the front of Machine Room 108, such as the storerooms such as vegetable compartment 110 are provided with, the storeroom 110 passes through pull type Door 110a and be opened and closed.Moreover, in the top of Machine Room 108, such as the storerooms such as freezing chamber 110 are provided with, the storeroom 110 are opened and closed by the door 110a of pull type.Though being had been omitted from moreover, illustrating, the top in ontology 102, such as it is provided with The storerooms such as refrigerating chamber 110, the storeroom 110 are for example opened and closed by the door 110a of rotary type.Due to compressor 111 with it is cold Condenser 112 can generate heat, so separated between the Machine Room 108 and each storeroom 110 by heat-insulated partition wall 110b.

In the present embodiment, using the condenser of so-called multi-streaming type as the condenser being set in Machine Room 108 112.The details of the condenser 112 of multi-streaming type will be aftermentioned, but at being constructed as follows: as shown in Figure 22 etc., between collector 113 It is connected by flat tube 14, has been set in parallel a plurality of flow path in the flat tube 114.Hereinafter, for the sake of convenient, by the composition Referred to as run-in index.Moreover, the composition is as shown in Figure 23 etc., collector there is also the condenser 112 of the multi-streaming type constituted as follows It is connected between 113 by a sinuous flat tube 114.Hereinafter, the composition is known as formula of wriggling for the sake of convenient.Moreover, each Cooling fin 115 is provided between flat tube 114.

Secondly, being illustrated to the effect of the composition.

Such as according to fig. 21 it is envisioned that: in order to expand storage amount without causing ontology 102 enlarged, that is, in order to make to store up Realize high volume in hiding room 110, it is generally desirable to relatively minimize Machine Room 108.However, if minimizing Machine Room 108, Then the volume of Machine Room 108 can be reduced, therefore, it is impossible to which the big component that can ensure sufficient heat dissipation capacity is arranged.

In contrast, in the present embodiment, using the condenser 112 of multi-streaming type.Even if the condenser 112 of multi-streaming type is small Type, it may have therefore high surface area can ensure sufficient heat dissipation capacity first, and can also be set to the machine after miniaturization In tool room 108.

However, there are multiple aspects that should be noted that in the case where condenser 112 are arranged.For example, as described above, in machine Other assemblies are also equipped in tool room 108, therefore, the configuration position of condenser 112 because of the position of other assemblies or is opened sometimes Position of oral area 109 etc. and be restricted.Moreover, especially in the case where refrigerator 101, due to being provided with refrigerating chamber or freezing chamber Equal storerooms 110, so need the influence for inhibiting fever for storeroom 110.Moreover, in actual, it is also desirable to consider with Easy connectivity etc. between aftermentioned piping 117 (referring to Figure 23 etc.).

That is, not only need condenser 112 small-sized in the case where the condenser 112 of multi-streaming type is set to refrigerator 101, And it is also required to carry out creative design to the setting position of the condenser 112 or setting direction.Hereinafter, first to condenser 112 multiple constructions (structure example A~structure example D) are illustrated, then, to the setting appropriate in structure example A~structure example D Example (setting example A~setting example D) is illustrated.

Referring to Figure 22 to Figure 24, to run-in index and construction, that is, structure example A that refrigerant is flowed to a direction is illustrated.With Under, for the sake of convenient, suffix " A " added and referred to as condenser 112A to the condenser 112 of the structure example A.Furthermore it is aftermentioned each Structure example is also identical, but in the case where carrying out universal description to each structure example, does not add suffix and be illustrated.

As shown in figure 22, between two cylindric collectors 113 of condenser 112A, be set in parallel more it is flat Pipe 114.Each flat tube 114 is formed with a plurality of flow path in inside, and each fluid communication is in each collector 113.Therefore, in flat tube 114 Interior, refrigerant flows in parallel.Referred to as multi-streaming type or concurrent flow (parallel flow) type according to such construction.

Moreover, the refrigerant for flowing into a collector 113 in entrance side flows through in flat tube 114, reach in outlet Another collector 113 of side.At this point, cooling fin 115 is contacted with each flat tube 114, therefore, the heat of each flat tube 114 is released, The cooling fin 115 is, for example, to be arranged between each flat tube 114 and metal sheet is formed as wavy.Hereinafter, convenient For the sake of, the position configured with each flat tube 114 and cooling fin 115 is known as body part 112a.The body part 112a is on the whole The rectangular-shape substantially thin in outer rim can be considered as.

Hereinafter, by the width direction of body part 112a, that is, in Figure 22 from a collector 113 towards another collector 113 Direction be known as X-axis.Moreover, by the short transverse of body part 112a, that is, the extension side of the cylindric collector 113 in Figure 22 To referred to as Y-axis.Moreover, by the thickness direction of body part 112a, that is, the direction orthogonal with X-axis and Y-axis is known as Z axis respectively.And And in Figure 22, the direction for indicating the arrow of X-axis, Y-axis and Z axis is set as positive direction, on the basis of body part 112a and to just Direction adds "+", and adds "-" to the negative direction opposite with the positive direction and be illustrated.

Connecting tube 116 is respectively arranged in each collector 113.The connecting tube 116 be in order to piping 117 (referring to Figure 24) It connects and is arranged, and be firmly attached to collector 113, on the other hand, the side being connect with the piping 117 outside the grade of heat-dissipating pipe 10 Be formed as the tubulose that for example can be bent or bend, and connect for example, by hard solder with piping 117.Hereinafter, for the sake of convenient, it will The connecting tube 116 of refrigerant inlet side is known as entrance side connecting tube 116a, and for the sake of convenience, by the connecting tube 116 of refrigerant exit side Referred to as outlet side connecting tube 116b.In said case, the direction of the entrance side connecting tube 116a substantially direction X-, outlet side connect The direction of adapter tube 116b essentially becomes the direction X+.

In the case where condenser 112A as described above, as shown in simplifying in Figure 23, flowed from entrance side connecting tube 116a The refrigerant entered is from the collector 113 for being provided with entrance side connecting tube 116a, as shown by arrow F, flows in each flat tube 114 another Root collector 113, and flowed out from outlet side connecting tube 116b.That is, refrigerant is flowed to a direction in the case where condenser 112A It is dynamic.At this point, refrigerant when flowing into entrance side connecting tube 116a be gas shape, by condenser 112 condense, as a result, from Become when outlet side connecting tube 116b flows out liquid.

Therefore, for condenser 112, the temperature of the collector 113 in entrance side is opposite to be increased, in outlet side The temperature relative reduction of collector 113.Moreover, the temperature highest of the entrance side of flat tube 114, temperature with close to outlet side and by Step reduces.That is, the body part 112a of condenser 112 produces Temperature Distribution including comprising collector 113.

Moreover, in the case where the limitation for not considering to be generated by setting position or setting direction, it is believed that entrance side connecting tube The freedom degree in the direction of 116a and outlet side connecting tube 116b is higher.Specifically, entering as shown in the solid line and dotted line in Figure 24 Mouth side connecting tube 116a can be set relative to body part 112a to various directions such as the direction X-, the direction Y+, the direction Z+, the directions Z- It sets.Similarly, outlet side connecting tube 116b can be relative to body part 112a and to the direction X+, the direction Y+, the direction Z+, the direction Z- It is arranged etc. various directions.

Furthermore though diagram has been omitted from, entrance side connecting tube 116a and outlet side connecting tube 116b may not strictly with it is described Direction, that is, each axis is orthogonal or parallel, can be slightly tilted, and can also significantly tilt relative to each axis.Though moreover, can will go out Mouth side connecting tube 116b is set to region R shown in Figure 24, but in said case, since entrance and outlet are close, so it is cold Matchmaker is possible to equably flow into whole flat tubes 114, therefore, in the case where condenser 112A, it is generally desirable to the greatest extent Entrance side connecting tube 116a and outlet side connecting tube 116b may be set to diagonally.

However, being connected to side of the piping 117 of each connecting tube 116 near condenser 112, corresponding to connecting tube 116 To.Thus, for example extending ground inlet porting side connecting tube 116a to the direction X-, and extend ground to the direction X+ when as shown in figure 24 When outlet side connecting tube 116b is arranged, from X-direction connecting pipings 117, therefore, in the feelings for considering the size comprising piping 117 It is required actual when needing the setting condenser 112A of certain degree in X-direction, that is, body part 112a width direction under condition Installation space.

Similarly, such as when extending ground inlet porting side connecting tube 116a along the direction Z+, in Z-direction, that is, body part On the thickness direction of 112a, the installation space of certain degree is needed.That is, installation space according to the direction of each connecting tube 116 and by Limitation.

< structure example B: the construction > that run-in index and refrigerant are flowed to both direction

Referring to Figure 25 to Figure 27, to run-in index and construction, that is, structure example B that refrigerant is flowed to both direction is illustrated.

As shown in figure 25, the essential structure of condenser 112B is identical as condenser 112A, in two cylindric collectors 113 Between, it has been set in parallel more flat tubes 114.Each flat tube 114 is formed with a plurality of flow path in inside, and each fluid communication is in each Collector 113.Therefore, in flat tube 114, refrigerant flows in parallel.Moreover, being provided with cooling fin between each flat tube 114 115。

However, a piece collector 113 is provided with entrance side connecting tube 116a and outlet side connects in the case where condenser 112B Both described in adapter tube 116b, sealing 13a is provided between the entrance side connecting tube 116a and outlet side connecting tube 116b. The sealing 13a is sealed the inside of cylindric collector 113.That is, sealing 13a is by the inside of a collector 113 It is divided into two ranges.Moreover, sealing 13a keeps the quantity of the flat tube 114 in entrance side relatively more, make in outlet The quantity of the flat tube 114 of side is relatively fewer.Reason is: refrigerant is gas shape in entrance side, therefore volume is big, in outlet side Become liquid by condensation, therefore volume reduces.Thereby, it is possible to improve efficiency.

In the case where condenser 112B as described above, as shown in simplifying in Figure 26, flowed from entrance side connecting tube 116a The gasiform refrigerant entered is as shown by arrow A, is being located at each flat tube that the side entrance side connecting tube 116a is more leaned on compared with sealing 13a After flowing to another collector 113 in 114, pass through in another collector 113, more connects by outlet side being located at compared with sealing 13a In each flat tube 114 of the side adapter tube 116b after reverse flow, flowed out from outlet side connecting tube 116b.That is, condenser 112B's In the case of, refrigerant is flowed to both direction.

In the case where the condenser 112B, if not considering the limitation generated by setting position or setting direction, enter The freedom degree in the direction of mouth side connecting tube 116a and outlet side connecting tube 116b is also higher.Specifically, such as the solid line in Figure 27 And shown in dotted line, entrance side connecting tube 116a can be relative to body part 112a and to the direction X-, the direction Y+, the direction Z+, the side Z- To etc. various directions be arranged.Similarly, outlet side connecting tube 116b can be relative to body part 112a and to the direction X-, the side Y+ It is arranged to the various directions such as the, direction Z+, the direction Z-.

In the case where the condenser 112B, the piping 117 of each connecting tube 116 is connected to also in the attached of condenser 112 Closely, the direction corresponding to connecting tube 116, therefore, installation space are restricted according to the direction of each connecting tube 116.Furthermore scheme It is had been omitted from though showing, entrance side connecting tube 116a and outlet side connecting tube 116b can be slightly tilted, can also be big relative to each axis Tilt to amplitude.

< structure example C: formula of wriggling and the construction > that collector is set to the same side

Referring to Figure 28 to Figure 30, the construction of the same side is set to sinuous formula and by collector 113, that is, by the entrance of refrigerant The structure example C for being configured at the same side relative to body part 112a with outlet is illustrated.

As shown in figure 28, it between two more small-sized cylindric collectors 113 of condenser 112C, is provided with sinuously A piece flat tube 114.The flat tube 114 is formed with a plurality of flow path in inside, and each fluid communication is in each collector 113.Therefore, exist In flat tube 114, refrigerant flows in parallel.Moreover, being provided with cooling fin 115 between the flat tube 114 turned back.Moreover, In the case where condenser 112C, the collector 113 of entrance side and the collector 113 of outlet side are set to together relative to body part 112a The position of side.

In the case where condenser 112C as described above, as shown in simplifying in Figure 29, flowed from entrance side connecting tube 116a The gasiform refrigerant entered is as shown by arrow A, flows to another collector 113 in flat tube 114, and from outlet side connecting tube 116b outflow.Furthermore the direction of collector 113 other than the direction vertical with flat tube 114 as shown in figure 28, also it is contemplated that Horizontal direction or coaxial direction etc. with flat tube 114, but in the case where condenser 112C, due to collector 113 itself compared with It is small, so think that the factor of space problem is the direction of connecting tube 116.

In the case where the condenser 112C, if not considering the limitation generated by setting position or setting direction, enter The freedom degree in the direction of mouth side connecting tube 116a and outlet side connecting tube 116b is also higher.Specifically, such as the solid line in Figure 30 And shown in dotted line, entrance side connecting tube 116a can be relative to body part 112a and to the direction Z+, the direction X-, the direction Y+, the side Y- It is arranged to the various directions such as the, direction Z+.Similarly, outlet side connecting tube 116b can be relative to body part 112a and to the side Z+ It is arranged to the various directions such as the, direction X-, the direction Y+, the direction Y-, the direction Z+.

In the case where the condenser 112C, the piping 117 of each connecting tube 116 is connected to also in the attached of condenser 112 Closely, the direction corresponding to connecting tube 116, therefore, installation space are restricted according to the direction of each connecting tube 116.Furthermore scheme It is had been omitted from though showing, entrance side connecting tube 116a and outlet side connecting tube 116b can be slightly tilted, can also be big relative to each axis Tilt to amplitude.

< structure example C: formula of wriggling and the construction > that collector is set to diagonal side

Referring to Figure 31, the construction of diagonal side is set to sinuous formula and by collector 113, that is, by the entrance of refrigerant and outlet The structure example D being configured on diagonal line relative to body part 112a is illustrated.

In the case where the condenser 112C, if not considering the limitation generated by setting position or setting direction, enter The freedom degree in the direction of mouth side connecting tube 116a and outlet side connecting tube 116b is also higher.Specifically, entrance side connecting tube 116a can be arranged relative to body part 112a to the various directions such as the direction Z+, the direction X-, the direction Y+, the direction Y-, the direction Z-. Similarly, outlet side connecting tube 116b can be relative to body part 112a and to the direction Z+, the direction X+, the direction Y+, the direction Z- etc. Various direction settings.

In the case where the condenser 112D, the piping 117 of each connecting tube 116 is connected to also in the attached of condenser 112 Closely, the direction corresponding to connecting tube 116, therefore, installation space are restricted according to the direction of each connecting tube 116.Furthermore scheme It is had been omitted from though showing, entrance side connecting tube 116a and outlet side connecting tube 116b can be slightly tilted, can also be big relative to each axis Tilt to amplitude.

Moreover, the setting direction of condenser 112 shown in the structure example A~structure example D also there are many.Such as it is condensing In the case where device 112A, it is contemplated that as shown in Figure 32 (a), the shape of the short transverse of body part 112a is set along gravity direction State, that is, collector 113 is along gravity direction and the state of flat tube 114 and setting face level.Furthermore connection is omitted in Figure 32 The diagram of pipe 116.

And, it is contemplated that as shown in Figure 32 (b), the shape of the width direction of body part 112a is set along gravity direction State, that is, collector 113 and setting face is horizontal and flat tube 114 along gravity direction state.And, it is contemplated that such as Figure 32 (c) institute Show, the state of the thickness direction of body part 112a is set along gravity direction；Or as shown in Figure 32 (d), relative to gravity side To the state etc. for the thickness direction that body part 112a is obliquely arranged.Furthermore though diagram is, also it is contemplated that relative to gravity side To the state that collector 113 is obliquely arranged (referring to Figure 39).
