Description

Receiver dryer of heat exchanger {Receiver dryer of heat exchanger}

The present invention is a receiver dryer for a heat exchanger with a filter, comprising a filter and a desiccant installed in the receiver dryer of the heat exchanger as an integrated unit and fixedly installed in the inlet pipe installed in the center of the receiver dryer and the receiver dryer It relates to a receiver dryer of the heat exchanger to be easily fixed in the body of the receiver dryer and to easily assemble the pressure switch on the top of the receiver dryer.

In general, an air conditioner such as a vehicle includes a heat exchanger to supply cold air or remove moisture to a vehicle interior, and the heat exchanger is provided by connecting a condenser that radiates heat while condensing to a compressor that compresses and supplies a refrigerant. The condenser is connected to a capillary tube and an evaporator to perform a heat exchange action, and to supply the cool air generated by the heat exchange action to the interior of the vehicle to use as a cooling device of the vehicle, and to remove moisture from the refrigerant. In order to do so, a receiver drier was installed.

In addition, the receiver dryer of the conventional heat exchanger acting as described above is provided with an inlet and an outlet pipe in its body, and an upper and a lower separator plate are installed on the inlet pipe to weld them together while assembling respective filters and desiccants therebetween. It was supposed to be fixed in a way.

However, the prior art as described above is provided with the filter and the desiccant separately, so as to assemble them sequentially with the separator plate and to fix the separator plate to the inside of the body by welding or the like. The assembly of the filter and the desiccant is cumbersome, and when the filter and the desiccant are assembled by the separator, the installation of the filter and the desiccant becomes difficult, and the welding operation of the body and the separator is very difficult, and the function of the receiver dryer is degraded. There were problems such as dots.

The present invention has been made in view of the above-mentioned conventional problems. The present invention provides a receiver dryer for a heat exchanger having a built-in filter, comprising a filter and a desiccant installed in a receiver dryer of the heat exchanger as an integrated unit and receiving the receiver. Fixed to the inlet pipe is installed in the center of the dryer to be fixed easily in the body of the receiver dryer and to provide a receiver dryer of the heat exchanger to easily assemble the pressure switch on the top of the receiver dryer, This will be described below in detail with reference to the accompanying drawings.

In assembling and installing a receiver dryer 4 connected to the unit and the inlet and outlet pipes 5 and 6 on one side of a heat exchanger unit 1 such as a condenser having a refrigerant supply inlet 2 and an outlet 3 formed therein. In the inlet pipe (5) located in the center of the body (7) of the receiver dryer (4), a unit in which a desiccant (9) and a filter (10) are integrated with a container (8) is fixedly installed and the container (8) ) Is assembled to the inlet pipe (5) integrally in the interior of the receiver dryer (4) and in this assembled state to caulk the body (7) with respect to the vertical position of the container (8), In the state of fixing the lower end of the inlet pipe (5) to the cap (11) and the receiver dryer (4) in which the container (8) is installed integrally brazed together with the unit of the heat exchanger in a continuous furnace and the container (8) There is no gap between the bodies (7) Is configured so that, as shown in Figure 5 to be configured to secure to form a fastening section (12) at a side upper end of the receiver-dryer 4, the body 7 is assembled thereto by fastening the pressure switch 13.

The present invention configured as described above is a receiver dryer connected to the unit and the inlet and outlet pipes 5 and 6 on one side of a heat exchanger unit 1 such as a condenser having the refrigerant supply inlet 2 and the outlet 3 formed therein. In assembling (4), a unit in which a desiccant (9) and a filter (10) are integrated into a container (8) in the inlet pipe (5) located in the center of the body (7) of the receiver dryer (4). It is fixedly installed and configured in one piece with the inlet pipe (5) and assembled in a state set in the receiver dryer (4), the container (8) of the receiver dryer (4) In the assembled state to the upper and lower positions of the body 7 by caulking and temporarily fixed.

In the above state, the lower end of the inlet pipe 5 is fixed to the cap 11, and the receiver dryer 4 in which the container 8 is installed is integrally brazed together with the unit of the heat exchanger in a continuous furnace to provide the container 8. ) And the filter 10 integrated with the container 8 and the desiccant 9 in a state in which no gap is generated between the body 7 and the body 7. It is firmly installed.

In addition, as shown in FIG. 5, the assembly of the pressure switch 13 can be easily performed by forming the fastening part 12 on one side of the upper end of the body of the receiver dryer 4 and fastening the pressure switch 13 thereto. Can be easily replaced in case of failure.
