The present invention relates to a receiver integrated condenser, more specifically, to the upper cap is integrally brazed and the body communicated to one side of the header pipe of the condenser receives the desiccant and filter net therein, and then combined with the lower cap for sealing It relates to a receiver integrated condenser for improving the structure to improve exchangeability and mounting.

In general, a cooling system is composed of a compressor, a condenser, an expansion valve, and an evaporator, and a refrigerant phase changes continuously while repeatedly circulating the members, and when the refrigerant contains foreign substances such as moisture, the cooling process is not performed smoothly. Blockages in the piping can cause the cooling system to malfunction, and at the same time to corrode the cooling system.

The condenser cools the compressed gaseous refrigerant to a liquid phase at an appropriate temperature. More specifically, the condenser passes a gaseous refrigerant into the refrigerant tube in contact with the heat dissipation fin and contacts the surface of the refrigerant tube and the heat dissipation fin. Heat exchange with air to liquefy to the appropriate temperature.

In the above process, although there are some differences depending on the refrigerant, a receiver drier is used to remove the water contained in the refrigerant in the liquid phase and deposits caused by corrosion of the metal.

Typically, the receiver dryer includes a receiver for storing the refrigerant of the liquid condensed in the condenser, the receiver has a desiccant and a filter therein, the filter functions to filter foreign matter from the refrigerant, the desiccant is moisture from the refrigerant It will perform the function of removing.

The receiver performs a function of storing the refrigerant in the liquid phase condensed in the condenser, filtering out moisture and impurities from the refrigerant, and maintaining the liquid until the vapor of the gaseous refrigerant flowing from the condenser is liquefied.

More specifically, the receiver is installed between the condenser and the expansion valve so that the cooling system can operate smoothly even if the amount of refrigerant consumed in the evaporator changes, and recently, the condenser and receiver An integrated condenser is proposed.

1 is a cross-sectional view showing a receiver structure of a conventional receiver integrated condenser.

Referring to the drawings, in order to perform the function as described above, the receiver 1 is a tubular body (40a) connected to one side of the condenser (2), the desiccant (42a) accommodated inside the body (40a) ) And the filtering net 43a, and after the desiccant 42a and the filtering net 43a are accommodated inside the body 40a, the lower cap 50a having the o-ring 45a integrally includes the lower cap 50a of the body 40a. It is coupled to the lower end of the receiver 1 is sealed.

Since the desiccant 42a and the filter net 43a are parts consumed according to their use and have to be exchanged when their lifespan expires, the desiccant 42a, the filter net 43a, and the lower part of the body 40a have to be replaced. It is required that the cap 50a be mounted and the work to be detached made easier.

Since the thread 40a is machined on the lower inner circumferential surface of the body 40a, the thread 75b portion that is machined on the outer circumferential surface of the lower cap 50a is coupled to correspond to the thread 75b of the body 40a. , The manufacturing process according to the screw processing of the receiver body 40a and the lower cap 50a becomes complicated.

Since the two parts are formed of different materials, there is a risk that the threads 75b of the lower cap 50a having a relatively high strength may be worn or the O-rings 45a may be broken, and the threads 75a may be processed in the body 40a for assembly. Due to this there is a problem that the material of the receiver 1 should be made thick.

In addition, when the desiccant 42a, the filtering net 43a, and the lower cap 50a are accommodated in the receiver 1, it is difficult to determine whether the assembly is completed completely and firmly, and the assembly of each part is not easy. There are disadvantages.

The present invention has been invented to solve the above problems, an object of the present invention is to enable the receiver and the condenser to communicate with each other by using a brazing joint, and after closing the receiver using a lower cap, the lower cap A fixing part formed by a fixing member and an insertion hole is provided at the bottom of the body of the receiver to support the body, and it is possible to improve exchangeability and installability by improving the coupling structure so that the parts accommodated in the receiver can be inserted in one piece or in a separate type.
