Description

Condenser with receiver {LIQUID RECEVER WITH CONDENSER}

The present invention relates to a condenser in which a receiver is disposed in a center header pipe, and integrates the receiver in the lower end of the center header pipe separately provided in the center to compensate for the disadvantages of the conventional receiver separate type and the receiver integrated capacitor.

In general, a heat exchanger for an air conditioner of an automobile includes a pair of header pipes 1a and 1b arranged side by side as shown in FIG. 1, a plurality of tubes 3 connecting between the header pipes, and the tubes. After the cooling fins 4 are filled between them, the baffles 1c provided in the header pipes 1a and 1b guide the flow path of the refrigerant to the zigzag along the tubes 3. And a receiver tank 5 next to the one side header pipe 1a, and flows in through the refrigerant inflow passage 51, and then passes only the liquid refrigerant through the refrigerant outlet passage 52 at the lower subcool zone. (10) to increase the cooling efficiency.

The receiver used to liquefy the refrigerant to be condensed has a separate type and an integrated type.

Separating the receiver type refers to a structure attaching the receiver as a separate process after the core of the condenser is welded as shown in FIG. 1, requires a separate structure and components for assembling the receiver, the vibration durability is weak, Because it takes up a lot of installation space, the compatibility is low, and the manufacturing cost is high.

Meanwhile, as shown in FIG. 2, the receiver integrated type brazes integrally by subassembly of the receiver tank 5 to the header 1a on the opposite side to which the refrigerant tube 3 is inserted. ), A pack (2) containing a desiccant or a cartridge is placed therein, and a stopper (7) which can be opened and closed at the bottom thereof.

However, the conventional receiver as described above has a large passage resistance because the pack 2 or cartridge containing the desiccant interferes with the flow of the refrigerant as shown in FIG. 2.

That is, when the refrigerant flowing along the tube (3) enters the tank (5) along the passage (51) connected to the side of the receiver, it passes through the desiccant pack (2) while moving from the upper side to the lower side. Moisture is removed, and then through the filtration section 8 provided above the stopper 7 below, the foreign matter is sent to the subcool zone 10 in a filtered state.

At this time, since the position of the desiccant pack 2 embedded above the filtration section 62 of the cap is close to the filtration section 8, there is a problem of blocking the upper side of the filtration section to resist flow.

Therefore, the present invention has been made in order to improve the conventional problems as described above, the main object of the invention is to install the receiver vertically in the center of the condenser to allow the refrigerant to flow in the left and right dispersed flow path, The center header pipe, which cuts the length of the tube, shortens the length of the tube, thereby greatly reducing the passage resistance.

It is another object of the present invention to be advantageous in maintaining balance of the entire condenser, and to facilitate attachment of the mounting mounting bracket to the header pipes on both the left and right sides thereof.

Characteristic configuration of the present invention for carrying out the above objects is divided into a baffle 113 of the interruption, divided into upper and lower spaces, the inlet pipe 119 connected to the top and the outlet pipe 120 connected to the bottom Center header pipe 114 having a; A receiver 122 having a desiccant pack 123 embedded in a lower space of the center header pipe; A left header pipe 115 and a right header pipe 116 provided on both left and right sides of the center header pipe; A left tube part 117 connecting the center header pipe and the left header pipe with a plurality of tubes 111 and filling cooling fins 112 between the tubes; And a right tube portion 118 connecting the center header pipe and the right header pipe with a plurality of tubes 111 and filling the cooling fins 112 between the tubes.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

3 is an overall configuration diagram showing a condenser of the present invention, and FIG. 4 is a partially enlarged cross-sectional view of FIG. 3.

As shown in the drawing, the condenser of the present invention includes a left header pipe 115 and a right header pipe 116 provided at both left and right sides, a center header pipe 114 provided in the middle, and the center header pipe 114. The left tube portion 117 and the right tube portion 118 provided on both sides of the right side is characterized.

That is, the center header pipe 114 having an inlet pipe 119 connected to the upper end and an outlet pipe 120 connected to the lower end after dividing the upper and lower spaces by the interrupted baffle 113. A receiver 122 formed by embedding a desiccant pack 123 in the lower space of the center header pipe, and left and right header pipes 115 and right header pipes 116 provided on both left and right sides of the center header pipe, respectively. A left tube part 117 connected between the center header pipe and the left header pipe with a plurality of tubes 111 and filled with cooling fins 112 between the tubes, the center header pipe and the right side; It consists of a right tube portion 118 connecting the plurality of tubes 111 between the header pipes, and filling the cooling fins 112 between the tubes.

At this time, the receiver 122 is provided with a stopper 125 at the bottom, so that the desiccant pack 123 and the filter 124 to be inserted therein can be replaced.

The condenser of the present invention configured as described above has the left tube portion 117 and the right tube portion 118 at the upper end thereof in which the fluid entering the center header pipe 114 through the inlet pipe 119 is partitioned by the baffle 113. Starting at the same time and flowing to the left header pipe 115 and the right header pipe 116, respectively, and the left and right header pipes 115 and 116 again through the left tube part 117 and the right tube part 118. Return to the header pipe 114.

The center header pipe 114 is changed into a liquid phase, and the water is removed through the desiccant pack 123 embedded therein, and the foreign material is removed through the filter 124 below, and then the outflow pipe 120 is removed. Going through.

On the other hand, the heat exchanger of the present invention as described above is very easy to attach and fix the mounting bracket 121 to the outer surface of the left header pipe 115 or the right header pipe 116, as well as to attach the bracket 121 As it is easy, it is easy to install on the body, so the compatibility is good.

The present invention as described in detail above is provided with a center header pipe in the center of the left and right header pipes to partition the left and right tube parts, and the receiver is provided in the center header pipe, and the refrigerant is distributed in the left and right tubes. The passage resistance can be greatly reduced because it flows into the flow path, and on the other hand, it is easy to install mounting brackets on both header pipes, and slimming due to proper distribution and division of the main header pipe in the center can be achieved. Has the possible advantages.
