Description

Condenser having integrated receiver drier

The present invention relates to a condenser, and more particularly, to a condenser having an integrated receiver which improves a coupling structure between a header pipe and a receiver tank.

In general, a condenser is a heat exchanger in which a heat exchange medium compressed at high temperature and high pressure from a compressor flows in and exchanges heat with lower ambient air to be a liquid heat exchange medium. The condenser is formed by alternately stacking tubes and heat sinks between a pair of header pipes to form a core, a bracket for attaching the core to the vehicle body, a damping material for protecting the condenser from the outside, and an inflow and outflow of a heat exchange medium. Inlet and outlet pipes are included. These condensers are combined with a receiver drier to temporarily store the heat exchange medium flowing from the condenser, and supply a complete liquid heat exchange medium to the expansion valve, and enclose the desiccant inside the non-condensed heat exchange medium. It absorbs moisture.

Recently, the receiver is located on the condenser's flow path, not the outlet side of the condenser, until the liquid zone of the heat exchange medium is developed in the receiver, and the lower side of the receiver is used as a subcooling zone where the liquid is cooled. Maintaining dryness

As shown in FIG. 1, the conventional condenser 10 has a plurality of first and second header pipes 11 and 12 disposed opposite to each other, and both ends of the header pipes 11 and 12. A plurality of communicating tubes 13, heat dissipation fins 14 interposed on the outer surface of the tubes 13, inlet and outlet pipes 15 and 16 provided in the first header pipes 11, And a baffle 17 installed in the header pipes 11 and 12 and a receiver 100 coupled to the second header pipe 12. The receiver 100 includes a receiver tank 110 communicated with the second header pipe 12 and a connection pipe 18, a desiccant 120 inserted into and fixed inside the receiver tank 110, and a filter. 130 and an end cap 140 for sealing both ends of the receiver tank 110.

The condenser 10 of this structure has a lower outside air while meandering inside the tube 13 partitioned by the baffle 17 as the high temperature and high pressure heat exchange medium introduced through the inlet pipe 15 is indicated by an arrow. Heat exchange with and is discharged through the outlet pipe 16 via the receiver (100).

However, the conventional heat exchanger 10 has the following problems.

First, in the state in which the header pipe 12 and the receiver 100 are preassembled by at least one or more connecting pipes 18, the clad sheet is coupled to the heat exchanger 10 through the brazing process. The number of parts, such as clad sheets and connecting pipes 18, increases, making the manufacturing process complicated.

Second, since the desiccant 120 or the filter 130 installed in the receiver tank 110 is a consumable part, these ones need to be replaced periodically when their lifespan expires. Therefore, the screw thread to the receiver tank 110 by forming a screw thread in the end cap 140 for the convenience of the operation during the exchange. At this time, it is difficult for the desiccant 120 or the filter 130 to open the lower cap 140 and replace them directly from the inside of the vehicle due to interference with the vehicle body or other components of the vehicle body. Therefore, the condenser 10 is removed from the cooling module of the vehicle body and exchanged in a state in which a working space is secured. In this regard, the repair process is complicated, and the cost is also increased.

Third, since the receiver 100 is disposed coaxially with respect to the condenser 10, it is impossible to block the so-called heat radiation gap which is a space generated from the outer circumferential surface of the header pipe 12 to the portion where the heat radiation chamber 14 is installed. It is not possible to guide the outside air flowing into the condenser 10.

An object of the present invention is to provide a condenser having an integrated receiver which is easy to manufacture because the receiver tank is integrally coupled with a fixed positional freedom with respect to the header pipe.

FIG. 11 is a diagram illustrating positional freedom of a receiver tank with respect to a header pipe according to an embodiment of the present invention. FIG.

Referring to the drawings, the header unit 110 is combined with the tank 120 to form a header pipe 130.

Is interposed.

Here, the receiver tank 130 formed integrally with the tank 120 to collect the heat exchange medium is installed to be inclined at a predetermined angle with the header pipe 130. As the position of the receiver tank 130 is changed, the position of the communication hole 141 installed in the receiver tank 130 is also changed so that the heat exchange medium with the header pipe 130 communicates.

More detailed description is as follows.

The receiver tank 130 has a degree of freedom within a predetermined range to change its position from side to side from the center of the header pipe 130. That is, the receiver tank 140 has a fluctuation distance that can block the heat dissipation gap (D) with respect to the header pipe 130 from side to side from the longitudinal direction of the tube (63) inserted into the header portion 110. It is coupled to the unit 120 integrally.

The center of the receiver tank 140 may be inclined from the center of the header pipe 130 to the left and right in the range of 0 ° to 90 ° in the longitudinal direction of the tube 63. More preferred position degree of freedom is tilted to any one direction angles, for example, the maximum inclination angle of the condenser, from which in the range (θ ₁₎ of approximately 100 ° and out against it a header pipe 130, the center of the receiver tank 140 is The range θ ₂ , around 130 °, is the preferred positional freedom. That is, θ ₁ is a degree of freedom in which the receiver tank 140 may be disposed left and right without changing the position of the header part 110, and θ ₂ is the header part 110 and the receiver tank 140. It is the degree of freedom that can be changed by changing all positions of.

Here, the maximum inclination angle of the receiver tank 140 with respect to the header pipe 130 is a range that can cover the heat radiation gap gap, which is a space generated between the outer peripheral surface of the header portion 110 and the end of the heat radiation chamber 64 Means. When wrapped around the heat dissipation gap, the receiver tank 140 can serve to guide the lower temperature air outside the condenser.

When the receiver tank 140 is inclined from the header pipe 130, the position of the communication hole 141 formed at the portion where the receiver tank 140 is coupled to the tank unit 120 is also changed. In addition, since the position of the communication hole 141 is changed according to the mounting position of the receiver tank 140, the shape of the header portion 110 and the tank portion 120 coupled thereto should also be changed.

As such, the receiver tank 140 is inclined with respect to the header pipe 130, and thus the shape of the header pipe 130 needs to be changed. Accordingly, the degree of freedom of the receiver tank 140 may be improved.

As described above, the condenser having the integrated receiver of the present invention can obtain the following effects.

First, since the receiver tank is integrally formed in the header pipe and the receiver tank can be coupled to the header pipe at an inclined angle, the positional freedom in which the receiver tank is mounted can be improved.

Second, the receiver tank surrounds the space generated between the outer circumferential surface of the header portion and the heat dissipation fan, thereby increasing the heat dissipation area, thereby improving thermal efficiency.

Third, since the communication hole can be formed in the receiver tank according to the mounting position thereof, and the tank portion and the receiver tank of the header pipe are integrally formed, the number of manufacturing steps is reduced. As a result, manufacturing costs are also reduced.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
