Description

Receiver dryer of heat exchanger {RECEIVER DRYER OF HEAT EXCHANGER}

The present invention provides a receiver dryer for a heat exchanger having a built-in filter, and includes a drying agent such as a filter installed in the receiver dryer of the heat exchanger, and combines a steel net at a lower side of the receiver dryer. In the installed state, the receiver dryer can be brazed integrally with the unit of the heat exchanger in a continuous furnace, and the installation state of the filter is firm while preventing the filter or the like from being carbonized or melted during the brazing. A receiver dryer for a heat exchanger.

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 conventional heat exchanger acting as described above is provided with a separate temperature control device for controlling the condensation state of the condenser, and the temperature control device controls the compression of the compressor while detecting the refrigerant temperature of the condenser. It was configured to control the condensation state by controlling the fan drive of the condenser motor installed on one side of the condenser, the receiver dryer is fixed to the upper portion of the body 101 of the receiver dryer as shown in FIG. And the pipe 103 is fixed to the pipe 103, and the filter 106 and the desiccant 107 are installed between the upper and lower separator plates 104 and 105 on the pipe, and below the body 101 of the refrigerant. It was comprised so that the flange block 108 which formed the entrance and exit ports 109 and 110 was welded and installed in the state which O-ring was interposed.

However, the above-described conventional ones, in installing the filter and the desiccant in the body 101 of the receiver drier, when the body 101 is brazed with these filters and the desiccant embedded therein, the wool or polyester Since the filter and the drying agent made of glass fiber or the like are carbonized or melted, the brazing operation of the body 101 cannot be performed in the state in which the filter or the like is embedded, and thus the filters and the drying agents are brazing operation of the body 101. There was a closed end to be assembled by a separate assembly after.

In addition, in assembling the filter and the desiccant, the outer diameter of the filter and the desiccant should be in close contact with the inner diameter of the body 101 so that there is no gap between them. There is a problem such that the function of the receiver drier is deteriorated since it becomes necessary and the action of the filter is not made smoothly through this gap.

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, and includes a drying agent such as a filter installed in a receiver dryer of the heat exchanger and includes a lower portion of the receiver dryer. One side is to combine the steel mesh and the filter dryer and the desiccant and the steel mesh is installed in the receiver dryer can be brazed integrally with the unit of the heat exchanger in a continuous (連 續 爐) and when the brazing the filter It is intended to provide a receiver dryer of the heat exchanger so that the installation state of the filter is firm while not being carbonized or melted, which will be described in detail below based on the accompanying drawings.

In assembling and installing the receiver dryer 1 connected to the unit and the inlet and outlet pipes 2 and 3 on one side of a heat exchanger unit such as a condenser having a refrigerant supply inlet and an outlet, the body of the receiver dryer 1 A screw 13 is formed in the injection molding 4 and the drying agent 7 and the filter 15 supported by the upper and lower separator plates 5 and 6 are installed on the body 4, and the body of the receiver dryer 1 is installed. (4) A cap 8 for supporting the outlet pipe 3 is provided below, and a steel mesh 9 is placed on the top of the outlet pipe 3 located on one side of the cap 8 with a cover 10. Installed and fixed to the receiver dryer (1) integrally brazed in a continuous furnace with the unit of the heat exchanger.

In addition, Figure 3 shows another embodiment of the present invention in the injection cap 801 is formed by integrally injecting the recessed portion 12 on the upper end of the bolt 11 of one side outlet pipe (3) formed on the recessed portion 12 The steel mesh 901 is installed and the injection cap 801 is configured to be installed on the body 4 with the rubber ring 14 interposed therebetween.

In the present invention configured as described above, in assembling and installing a receiver dryer (1) connected to the unit and the inlet and outlet pipes (2) and (3) on one side of a heat exchanger unit such as a condenser having the refrigerant supply inlet and the outlet, The desiccant 7 and the filter 15 supported by the upper and lower separator plates 5 and 6 are installed in the inlet pipe 2 located in the center of the body 4 of the receiver dryer 1.
