It is formed with female thread 22a in the upper end of the inner peripheral surface of reservoir main body 22, makes the top of the outer peripheral face at connector 23 be formed External screw thread 23a chimeric with the female thread 22a screw thread of reservoir main body 22, thus connector 23 is dismounted and is arranged on liquid storage freely The upper end of device main body 22.Additionally, utilize o-ring 26 to leaning on compared with female thread 22a in the inner peripheral surface of reservoir main body 22 The part of lower section seals with the part by the top compared with external screw thread 23a in the outer peripheral face of connector 23.

At the height and position between reservoir side refrigerant inflow port 24 and refrigerant outflow port 25 in reservoir 2, Carry out in being such as provided with reservoir 2 at the height and position between the 1st heat exchange paths P1 and the 2nd heat exchange paths P2 up and down The partition member 27 divided, being provided with in reservoir 2: make compared with partition member 27 reservoir side cold-producing medium on the lower flow into 1st spaces 28 of mouth 24 connection；And make compared with partition member 27 reservoir side refrigerant outflow port 24 connection by the top 2nd space 29.It addition, be configured with desiccant bag 32 in the 1st space 28 in reservoir 2, this desiccant bag 32 has ventilative Property and liquid permeability are also accommodated with desiccant 32a, and the length direction of this desiccant bag is towards above-below direction.In reservoir 2 Being configured with filter 33 in 2nd space 29, this filter 33 flows into the cold-producing medium in the 2nd space 29 from by suction tube 31 Middle removing foreign body.

Partition member 27 is plastic discoideus, the inner circumferential of the reservoir main body 22 of its outer peripheral face and reservoir 2 Sealed by o-ring 34 between face.Central part at partition member 27 is formed and makes the 1st space 28 and passing through that the 2nd space 29 connects Perforation 35.It addition, on the upper surface of partition member 27, be integrally formed with filter holding member 36, keep at filter Filter 33 is installed on parts 36.Filter holding member 36 is configured to include: plectane 36a, and it is arranged at spaced intervals The top of partition member 27；And linking part 36b, its compartment of terrain spaced apart in the circumferential direction is located in the upper surface of partition member 27 Being present on a circumference of outer circumferential side edge portion, and linked integratedly with plectane 36a by partition member 27, this filter is protected Hold parts 36 and keep filter 33 in the way of the gap between by adjacent linking part 36b blocks.

It is fixed on partition member 27 in the upper end of suction tube 31 is inserted into the through hole 35 of partition member 27.Suction Pipe 31 is configured to include: short vertical component effect 31a, and it has specific length from upper end；Rake 31b, it is from short vertical component effect 31a court Tilt downwards and to the radial outside of reservoir main body 22；And long vertical component effect 31c, its be connected with the lower end of rake 31b and Extend the most as the crow flies.The periphery of the lower ending opening of long vertical component effect 31c is positioned in inclined plane, the lower surface of long vertical component effect 31c It also is located in this inclined plane.

In the edge, both sides of desiccant bag 32 at least on some, herein is in a side edge part and be provided with vertically side To extending and the cylindrical portion 37 of upper and lower both ends open.And, the long vertical component effect 31c of suction tube 31 is at least to make long vertical component effect 31c The mode all exposed downwards from cylindrical portion 37 of lower surface pass in the cylindrical portion 37 of desiccant bag 32, utilize suction tube The long vertical component effect 31c of 31 keeps the posture of desiccant bag 32.

Condenser 1 constitutes cooling cycle system and as automobile together with compressor, expansion valve (decompressor) and vaporizer Air-conditioning and be equipped on vehicle.

In the condenser 1 of said structure, by the vapor phase refrigerant of the High Temperature High Pressure after compressor compresses from cold-producing medium Inlet part 16 and refrigerant inlet 15 by and flow in the entrance liquid collecting portion, condensation part 11 of right side catch box 4, in this system Cryogen condenses and flows into left side catch box 5 in the heat-exchange tube 3 of the 1st heat exchange paths P1 within the period of left side flowing In outlet liquid collecting portion 13, condensation part.Flow into the cold-producing medium in the outlet liquid collecting portion 13, condensation part of left side catch box 5, from liquid collecting portion Side refrigerant outflow port 19 and reservoir side refrigerant inflow port 24 pass through the 1st space 28 to reservoir 2.

When 1 space 28 in cold-producing medium flows into reservoir 2, stop suction tube by the effect of desiccant bag 32 The 31 perisporium direct collisions of reservoir main body 22 with reservoir 2 because of the force and velocity of a current of cold-producing medium, thus suppress the generation of abnormal sound.And And, cause owing to utilizing suction tube 31 to suppress the force and velocity of a current of cold-producing medium by the 1st space 28 flowed in reservoir 2 is dry The movement of drying prescription bag 32, therefore cold-producing medium flowing in the 1st space 28 of reservoir 2 becomes smooth and easy.Further, it is possible to prevent because of Moving of desiccant bag 32 and the pulverizing of desiccant in the desiccant bag 32 that causes, its result is, can prevent the generation of foreign body.

The cold-producing medium flowed in the 1st space 28 of reservoir 2 is gas-liquid mixed phase cold-producing medium, in this gas-liquid mixed phase cold-producing medium The mixed phase cold-producing medium based on liquid phase be stranded in the bottom in reservoir 2 because of gravity.It addition, in reservoir 2, pass through Make cold-producing medium contact with the desiccant in desiccant bag 32 and the moisture in cold-producing medium is removed.It is stranded in reservoir 2 bottom Mixed phase cold-producing medium based on liquid phase passes through to suction tube 31 from lower ending opening, so from suction tube 31 by and Flow in the 2nd space 29.From suction tube 31 by and flow in the cold-producing medium in the 2nd space 29 containing the situation of foreign body Under, this foreign body is removed by filter 33.

Flow into the mixed phase cold-producing medium based on liquid phase in the 2nd space 29 of reservoir 2, from reservoir side cold-producing medium Flow export 25 and liquid collecting portion side refrigerant inflow port 21 pass through the entrance liquid collecting portion of supercooling portion 14 to left side catch box 5 In.

Enter to the cold-producing medium in the entrance liquid collecting portion of supercooling portion 14 of left side catch box 5 in the 2nd heat exchange paths P2 Towards being over cooled the supercooling portion outlet liquid collecting entering to right side catch box 4 afterwards in the period of right side flow in heat-exchange tube 3 In portion 12, so from refrigerant outlet 17 and refrigerant outlet parts 18 by and flow out, and be transported to via expansion valve Vaporizer.
