Description

How to assemble a condenser integrated receiver dryer and its receiver dryer {Receiver drier of air-con system for vehicle}

The present invention relates to a method for assembling a receiver integrated receiver dryer and a receiver dryer thereof, and more particularly, to have a receiver dryer for supplying a necessary amount to an evaporator by adapting a refrigerant liquefied in a condenser of an automotive air conditioner to a cooling load. It is about the provision of a capacitor.

The vehicle is equipped with an air conditioning system consisting of a heating system and an air conditioning system for the purpose of indoor ventilation to adjust the room temperature to the appropriate state during the summer and winter.

The air conditioner as described above is provided with an air-conditioning duct which is an integral injection assembly, and an air suction door for controlling the inflow of external air and circulation of indoor air and a blower unit for forced ventilation of the air introduced at the side of the air-conditioning duct. It is provided.

An evaporator and a heater core are sequentially arranged in front of the blower unit, and the passage of the evaporator and the heater core is defined by a temperature control door.

The front of the evaporator and the heater core is a configuration in which cold and warm air flows into the room through a vent hole provided on a deflector or an instrument panel connected to an interior of a vehicle by a distribution door.

The air conditioning system used in the above air conditioner is a compressor that converts the refrigerant into a gas of high temperature and high pressure → a condenser that liquefies the gas of high temperature and high pressure → removes moisture and dust, and supplies the necessary amount to the evaporator according to the cooling load. Receiver dryer that temporarily stores refrigerant → Expansion valve to make it look like frost of low temperature and low pressure to facilitate heat exchange in evaporator → It consists of evaporator that generates cold air by heat exchange with air introduced by blower unit. Repeat with the compressor again.

As described above, the conventional receiver drier temporarily storing the refrigerant supplied to the evaporator and removing foreign matters or moisture contained in the refrigerant is installed independently between the capacitor and the expansion valve, thereby reducing space utilization of the engine room.

In particular, a separate refrigerant pipe for fixing the receiver dryer, a refrigerant pipe for connecting the condenser together with a clamp and a screw, etc. should be further provided, thereby providing a cause of cost increase due to the addition of unnecessary parts and degrading the overall assemblage. To provide a cause such as.

To solve this problem, a configuration in which the receiver dryer is integrated with the head assembly of the condenser has been developed and used, and representative examples thereof are illustrated in FIGS. 1 and 2.

Looking at it; A tank 13 having a semi-circular cross section, a head assembly 12 composed of a header 14, a tube 15 coupled to the header 14, and an interior of the tank 13 and the header 14. The separator 16 is interposed, and the center 17 is positioned between the tube 15 and the tube 15 to be brazed and coupled to the condenser 10.

The receiver dryer 11 is integrally mounted on the side of the head assembly 12 of the capacitor 10.

Engaging portions of the head assembly 12 and the receiver dryer 11 are further provided with coupling surfaces 18 and 19 to provide easy coupling, and the desiccant is sealed with a nonwoven fabric in the receiver dryer 11. Desiccant pack 20 is built.

The coupling surfaces 18 and 19 of the head assembly 12 and the receiver dryer 11 are configured to form through holes 21 and 22 to allow refrigerant flow.

Conventionally, such a receiver dryer is brazed with a head assembly, and in this process, a desiccant pack built into the receiver dryer is damaged, and thus, the receiver dryer may not function properly when the vehicle is mounted.

This is because the nonwoven fabric that seals the desiccant does not withstand the high temperatures generated during brazing and melts.Since the desiccant pack is not fixed to the body of the receiver dryer, it is contained in the refrigerant because of the high risk of damage due to external pressure such as vibration. It will not be able to perform the function of removing the moisture.

In addition, in order to form the coupling surface to integrate the head assembly of the condenser and the receiver dryer, the head assembly and the receiver dryer have to be deformed and complicated processing processes such as the formation of an arc for refrigerant flow are required. There are many problems, such as lowering, resulting in a rise in production costs due to a complicated production process.

Accordingly, the present invention improves the length controllability of the receiver dryer by improving the relationship of integrally mounting the receiver dryer in the head assembly constituting the condenser as invented to solve the above problems;

It can contribute to the improvement of the quality of the condenser by faithfully performing the function of removing the moisture contained in the refrigerant while contributing to the ease of manufacturing and cost reduction by eliminating the extra work such as the separate bonding surface and hole formation. The purpose is to make it possible.

It consists of an upper cap 153 and a lower cap 154 sealing the upper and lower sides of the drying control assembly 152 and the receiver dryer body 151.

One side of the receiver dryer body 151 forms an open coupling portion 155 to be coupled to the tank 105 of the head assembly 110.

The coupling part 155 forms a coupling flange 156 integrally protruding to the outside of the receiver dryer body 151, and has a curvature of the tank 105 connected to the inner surface 157 of the flange 156. It is desirable to have the same curvature as to improve the connection property.

The drying control assembly 152 embedded in the receiver dryer body 151 is for preventing the flow of the desiccant pack 161 and the desiccant pack 161 sealed with a desiccant 160 made of non-woven fabric or stainless mesh. The pack support 162 is configured.

The pack support 162 is composed of a disc-shaped support plate 163 and a support rim 164 that is bent from the outside of the support plate 163, the refrigerant passing through the desiccant pack 161 on the support plate 163. A plurality of through holes 165 are formed to be possible.

The support rim 164 is preferably formed so that the end portion of the rim is larger than the inner diameter of the receiver dryer body 151 so as not to be easily separated or flow when inserted into the receiver dryer body 151 so as to be expanded to the outside. .

The upper cap 153 and the lower cap 154 for sealing the upper and lower sides of the receiver dryer body 151 is also composed of a rim 171 formed by bending the outer end of the cap plate 170 of the plate-like body, Rim 171 is configured to be forcibly coupled to open to the outside like the support rim 164.

One cap of the upper cap 153 and the lower cap 154 may be screwed in addition to the forced coupling for the post-maintenance of the desiccant pack 161, the drying control assembly 152 is built-in Caulking (180) may be applied to the receiver dryer body 151 so that the flow or departure of the drying control assembly 152 may be prevented at the source.

In the case of Figure 9 shows a second embodiment of the present invention, the fixing means for preventing separation of the tank 105 and the receiver dryer body 151 of the head assembly 110 by external pressure, such as vibration during brazing progress The structure further provided with 185 is shown.

The fixing means 185 may be a variety of means such as a clamp or a clip connecting the flange 156 formed on the coupling portion 155 of the receiver dryer 150 and the end of the tank 105 or the flange phase.

As another example of the fixing means 185, as shown in FIG. 10, an end of the flange 156 formed at the engaging portion 155 of the receiver dryer 150 may be extended to fix the end of the tank 105 by walking. The structure which integrally formed the locking step 187 is shown.

In the case of Figure 11 as showing another example of the assembly of the receiver dryer (150);

The tank 105 of the head assembly 110, the receiver dryer body 151 and the cap of one of the upper and lower caps (153, 154) is brazed first, and then the dry control assembly 152 and the other cap are closed by welding. It is to be done.

The present invention as described above;

First, when the desiccant is sealed with a sealant 160 made of a stainless steel mesh body, the receiver dryer 150 is assembled, and then the assembled receiver dryer 150 is brought into close contact with the tank 105 of the head assembly 110 to obtain a condenser. 100) can be integrated with.

Assembly of the desiccant pack 161 in the receiver dryer 150;

After determining a position by first inserting one pack support 162 into the inside of the receiver dryer body 151, a desiccant pack 161 sealed with a desiccant 160 is inserted, and the rest of the pack support 162. Insert and fix the desiccant pack (161).

The desiccant pack 161 has a diameter of the support rim 164 of the pack support 162 is larger than the inner diameter of the receiver dryer body 151 to determine the position in a solid state, and finally the upper cap 153 and the lower The cap 154 may be finished.

When insertion of the drying control assembly 152 composed of the pack support 162 and the desiccant pack 161 is completed, the caulking 180 is performed toward the outer end of the pack support 162 from the outside of the receiver dryer body 151. It may be possible to prevent more firm positioning and departure and flow.

When the assembly of the receiver dryer 150 is completed as described above, the coupling part 155 of the receiver dryer 150 is connected to one side of the tank 105 and then coupled by brazing to receive the receiver dryer 150 in the condenser 100. Integrate with.

When the receiver dryer 150 and the tank 105 are coupled to each other, the inner surface 157 of the flange 156 integrally formed at the coupling portion 155 has the same curvature as that of the tank 105. As it is more easily connected to be able to increase the bonding force.

When the desiccant is sealed with a non-woven sealant 160;

The caps of the upper and lower caps 153 and 154 are combined with the receiver dryer body 151 first, and then firmly assembled with the tank 105 of the head assembly 110 and brazed by a brazing furnace, followed by a desiccant pack 161. And the drying control assembly 152 consisting of the pack support 162 may be inserted and welded after finishing with the last remaining cap.

When the receiver dryer 150 of the present invention is mounted as described above, since the coupling part 155 of the receiver dryer 150 is open, the refrigerant flows only in the tank 105 of the head assembly 110 to which the receiver dryer 150 is opened. Since the holes need to be formed, a considerable process can be reduced in manufacturing the receiver 100 integrated receiver dryer 150.

The receiver dryer 150 and the condenser 100 are prevented from being dislodged or damaged due to external pressure such as vibration, thereby preventing the receiver dryer 150 from performing its original function.

This is possible because the pack support 162 is kept firm on both sides of the desiccant pack 161 and the movement of the pack support 162 is restricted by the caulking 180 performed outside the receiver dryer body 151.

In addition, in order to further solidify the rigidity of the receiver dryer 150 brazed to the tank 105 of the head assembly 110 by using a separate fixture 185 between the receiver dryer 150 and the tank 105 phase. By further fixing it can be prevented from being easily separated.

In particular, the length of the receiver dryer 150 and the header 105, without being hindered in the combined position can be freely adjusted.

The present invention as described above by providing an improved receiver dryer to prevent damage to the desiccant pack that may occur during the combination and to eliminate the additional work such as separate bonding surface and hole formation contributes to ease of manufacture and cost reduction, By making it possible to faithfully perform the function of removing the moisture contained in it can achieve an excellent effect of improving the quality of the condenser.
