The present invention relates to a receiver integrated condenser, and more particularly, by easily detaching the lower cap to the tank body of the receiver by one touch, the receiver is integrated to simplify assembly and disassembly and to facilitate maintenance. Relates to a condenser.

In general, the condenser liquefies by exchanging the high-temperature and high-pressure refrigerant delivered from the compressor to the outside air, and the receiver is installed between the condenser and the expansion valve on the cooling system to transfer the amount of refrigerant liquefied in the condenser to the evaporator according to the cooling load. It is a temporary storage for supply.

In addition, a desiccant and a filter are provided inside the receiver to filter out moisture and impurities contained in the refrigerant.

These condensers and receivers are generally combined in separate forms, but there is a problem in terms of space utilization of a limited engine room. Recently, a condenser integrated condenser in which a condenser and a receiver are integrated has been proposed and put into practical use.

Looking at the conventional receiver integrated condenser as described above in Figure 1 as follows.

In order to dissipate the high temperature and high pressure refrigerant compressed by the compressor (not shown), the plurality of plate-shaped tubes 1b having the cooling fins 1a are installed in the horizontal direction, and the cores 1 are installed at equal intervals. And a header (2) communicating with the tube (1b) vertically on both sides of the tube (1b) to form a condenser (3).

In addition, one side of the header 2 has a desiccant 6 embedded therein, and a receiver 8 which separates gaseous refrigerant gas and sends only liquefied refrigerant to an expansion valve (not shown) is integrated. It is formed.

In addition, the receiver tank 4 and the lower cap 5 are screwed and fixed to prevent leakage of the refrigerant.

However, by combining the receiver tank 4 and the lower cap 5 by screwing, the work time for disassembling or assembling the lower cap 5 is long, and there is a problem that assembly or disassembly is possible only by using a separate tool. there was.

That is, the desiccant 6 for removing moisture in the receiver tank body 4 is used and exchanged for a predetermined time, using a wrench (not shown) in the hexagonal wrench ball 7 formed in the lower cap 5. By disassembling the lower cap 5 from the receiver tank body 4, there is also a problem that the workability is reduced.

The present invention has been made to solve the conventional problems, and an object thereof is to provide a receiver-integrated condenser to easily disassemble and assemble the receiver tank body and the lower cap in one-touch manner without using a separate tool.

The present invention for solving this object is a first header and a second header spaced apart in parallel to the first header, and the tube is installed side by side so that both ends are in communication with the first header and the second header, In the receiver integrated condenser having a cooling fin interposed between the tubes and a receiver integrally formed to communicate with any one of the first header or the second header, the receiver is in the longitudinal direction on the inner peripheral surface of the tank body Guide grooves formed in the form, connected to the end of the guide groove and the fixed groove formed in the circumferential direction of the tank body, and the lower cap formed with a coupling protrusion to be inserted along the guide groove to be coupled to the fixed groove It consists of.

In addition, the lower side of the fixing groove further comprises a locking groove into which the engaging projection of the lower cap is inserted.

In addition, the elastic means is interposed between the tank body and the lower cap of the receiver.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As illustrated, the receiver integrated condenser 100 may be installed at equal intervals while installing a plurality of tubes 32 including cooling fins 31 for radiating heat of a high temperature and high pressure refrigerant compressed by a compressor. The core 30 is formed, and the first header 10 and the second header 20 communicate with each other in an upright position on both sides of the plurality of cores 30, and the receiver 40 is provided on one side of the second header 20. ) Is formed integrally.                     

Baffles 10a, 10b, 20a, and 20b are installed in the first header 10 and the second header 20 to circulate the refrigerant in zigzag, and the upper part of the first header 10 is provided. A coolant inlet 11 is formed, and a coolant outlet 12 is formed in the lower portion.

3 is a perspective view showing a receiver according to the present invention.

The receiver 40 is composed of a tank body 41 and a lower cap 42 coupled thereto.

The tank part 41 serves to separate only the refrigerant gas in the bubble state contained in the liquefied refrigerant sent from the condenser and to send only the liquid refrigerant to the expansion valve (not shown). Guide groove 41a formed along the longitudinal direction, and is connected to the end of the guide groove 41a and consists of a fixed groove 41b formed along the circumferential direction.

Also, The locking groove 41c is formed in the lower direction of the fixing groove 41b and into which the coupling protrusion 42a of the lower cap 42 to be described later is inserted.

In addition, the tank body 41 is provided with a desiccant 50 for removing moisture and a filter 60 therein.

The lower cap 42 is coupled to the tank body 41 to prevent leakage of the refrigerant, the coupling protrusion 42a coupled to the fixing groove 41b along the guide groove 41a of the tank body 41. ) Is formed, and the O-ring 42b is coupled to the outer circumference.

That is, as shown in FIGS. 4 and 5, the coupling protrusion 42a formed on the lower cap 42 is inserted along the guide groove 41a formed on the inner circumferential surface of the tank body 41 and the fixing groove 41b is formed. According to the one-touch assembly, it is inserted into the locking groove (41c) connected to the fixing groove (41b) is more firmly fixed.

6 is another embodiment of the present invention, the lower portion by the elastic force of the elastic means 70 to be made through the elastic means 70 such as a coil spring between the tank body 41 and the lower cap 42 By pushing the cap 42 is to improve the adhesion of the lower cap 42 coupled to the tank body 41.

In the meantime, reference numerals 21 and 42c indicate through-holes connected to the condenser to allow the refrigerant to flow.

Referring to the operation according to the invention in detail as follows.

Although not shown in the figure, the receiver integrated condenser 100 of the present invention is positioned between the compressor and the expansion valve to configure a refrigeration cycle.

The refrigerant, which is in a high temperature and high pressure state in the compressor, flows into the refrigerant inlet 11 of the first header 10 and flows to the second header 20 through the tube 32, thereby exchanging heat with the outside air by the cooling fin 31. Cooling condensation.

At this time, the refrigerant flows to the second header 20 by the baffle 10a on the first header 10, and the first header 10 again by the baffle 20a on the second header 20. Heat exchange is achieved while flowing to.

The refrigerant flowing in the first header 10 flows back to the second header 20 by the lower baffle 10b, and saps through the through hole 21 communicating with the second header 20. The refrigerant flows into the gas 40.                     

The relatively liquid refrigerant flowing into the receiver 40 is separated into gas and liquid by its own weight while passing through the desiccant 50 and the filter 60.

That is, the gaseous refrigerant is collected in the upper portion of the receiver 40, the liquid refrigerant passes through the desiccant 50 by its own weight and falls to the lower portion of the receiver 40.

The refrigerant liquefied in the receiver is flowed to the expansion valve through the refrigerant outlet 12 of the first header 10 to form a refrigeration cycle.

That is, the coolant is zigzag and radiates heat between the first header 10 and the second header 20 by baffles 10a, 10b, 20a, and 20b, and liquefies while passing through the receiver 40. The refrigerant is sent to the expansion valve.

Then, in order to replace the filter 60 and the desiccant 50 used for a certain period of time contained in the receiver 40, the lower cap 42 is removed from the tank body 41 of the receiver 40 and replaced. Done.

When the lower cap 42 is separated or coupled from the tank body 41 of the receiver 40 will be described in detail.

The engaging projection 42a formed on the outer circumference of the lower cap 42 is inserted along the guide groove 41a formed in the longitudinal direction on the inner circumferential surface of the tank body 41 of the receiver 40 and circumferentially formed on the inner circumferential surface thereof. The lower cap 42 is fixed to the tank body 41 as it is rotated in the fixing groove 41b.

At this time, the force that pushes the lower cap 42 by the pressure of the refrigerant contained in the receiver 40 is generated so that the lower cap 42 is not separated from the tank body 41.                     

In addition, the coupling protrusion 42a is inserted into the locking groove 41c connected to the fixing groove 41b to be more firmly fixed.

In addition, through the elastic means 70 between the tank body 41 and the lower cap 42 is to further improve the coupling force of the lower cap 42 by the elastic force.

When the lower cap 42 is fixed to the tank body 41 in this way, leakage of the refrigerant is prevented, and the lower cap 42 is removed from the tank body 41 when the desiccant 50 and the filter 60 are replaced. It can be easily removed.

According to the receiver integrated condenser of the present invention as described in detail above, by simply coupling the lower cap to the tank body of the receiver in one-touch, workability is improved.

In addition, by disassembling and assembling without the need for tools, maintenance time can be shortened.
