Description

Condenser integrated receiver receiver {Condenser integrated with receiver dryer}

The present invention relates to a condenser, and more particularly, to a receiver dryer integrated condenser in which the receiver dryer is integrally coupled.

In general, the condenser serves to condense (liquefy) the high-temperature and high-pressure refrigerant flowing out of the compressor with the outside air, and a receiver drier is installed between the condenser and the expansion valve to adjust the amount of the refrigerant liquefied in the condenser according to the cooling load. It is temporarily stored for supply to the evaporator and at the same time serves to separate the uncondensed refrigerant from the condenser. In recent years, a receiver dryer integrated condenser in which the condenser and the receiver dryer are integrated so as to reduce the space utilization and the amount of the refrigerant has been put into practical use.

Referring to the conventional receiver dryer integrated condenser 50 with reference to Figure 1, the receiver dryer integrated condenser 50, a pair of header pipes 22 and 24 spaced apart in parallel to each other, the pair of header pipes A pair of condenser 10 including a plurality of tubes 11 inserted at both ends and spaced apart from each other, and a plurality of heat dissipation fins 12 interposed between the tubes 11 and 24, and the pair It includes a receiver dryer 30 in communication with the header pipe 22 on one side of the header pipes 22 and 24 and fixed to the header pipe 22 by brackets 41 and 42.

Here, the receiver dryer integrated condenser 50 is mainly formed of aluminum to facilitate heat exchange, and integrally couples the condenser 10 and the receiver dryer 30 through brazing. Meanwhile, the receiver dryer integrated condenser 50 undergoes a temporary assembly process for fixing the brackets 41 and 42 before brazing.

However, since the conventional receiver dryer integrated condenser 50 uses separate fixing parts such as rivets or bolts and nuts to fix the brackets 41 and 42, the required cost increases as well as the manufacturing process. There is this complicated problem.

In addition, since the conventional receiver dryer integrated condenser 50 is temporarily assembled through welding, not only is it difficult to control the quality, but also requires a work by a skilled worker, and there is a problem of weakening the corrosion resistance of the product by the heat of welding.

The present invention has a structure in which the bracket is assembled and fixed without using consumable parts for fixing the bracket, thereby reducing cost and simplifying the manufacturing process, and does not require expensive welding equipment because no welding process is performed. Therefore, the purpose of the present invention is to provide a receiver dryer integrated condenser that can not only reduce equipment investment cost but also can easily control quality, improve workability, and improve corrosion resistance.

The present invention, a condenser having a header pipe; A receiver dryer coupled to the header pipe and including a tubular body formed to penetrate an insertion groove along a portion of an outer circumferential side thereof; A baffle fitted into the insertion groove to block a lower end of the body of the receiver drier and having a fitting protrusion projecting out of the body in a state of being fitted into the insertion groove; And a bracket coupled to the body and the header pipe so as to allow the inflow and outflow of the refrigerant between the body and the header pipe, and the fitting protrusion being fitted to determine a coupling position with the body. do.

Here, the bracket, the body is inserted into the inner circumferential direction in the axial direction, and a seating portion for mounting a portion of the outer peripheral side of the body, provided in the seating portion, the fitting means for fitting the fitting projections, the seating portion A refrigerant inlet and a refrigerant outlet coupled to the refrigerant inlet and the refrigerant outlet of the body so as to closely cover a portion of the outer circumferential side of the header pipe and to allow the inflow and outflow of the refrigerant between the body and the header pipe. Contains wealth. In this case, the fitting means may be a fitting groove formed on one side of the lower end of the seating portion or a sliding groove formed along the insertion direction of the receiver dryer body. Further, the fitting means is a coupling groove which is located on the extension line of the insertion groove formed in the body, wherein the baffle may further include an extension coupling portion which is integrally extended from the fitting protrusion to fit in the coupling groove. In addition, the bracket may further include a cover extending to the seating portion and surrounding the outer circumferential side of the body.

On the other hand, the present invention further comprises a fitting pin for fitting the refrigerant inlet and the refrigerant inlet or the refrigerant outlet and the refrigerant outlet in the tubular shape to suppress the axial movement of the bracket relative to the body.

The receiver dryer integrated condenser according to the present invention provides the following effects.

First, it is economical because it does not use consumable parts such as rivets or bolts to fix the bracket, and can reduce cost and simplify the manufacturing process.

Second, because the bracket and the receiver dryer are fixedly connected to each other by assembling rather than welding, expensive welding equipment is not required. Therefore, investment cost can be reduced, quality control is easy, and workability is improved. Can be.

Third, since welding is not performed, corrosion resistance due to heat of welding can be prevented, thereby improving the reliability of the product.
