Description

Wing sub-cooling capacitor for air conditioner {Lying Type Condenser for A / con System}

The present invention relates to a wading subcooled condenser, and improves the receiver dryer tank part so that the standing subcooled condenser can be installed in a wading manner without large structural change.

In general, an air conditioner system of a vehicle using a subcool condenser includes a compressor 11 for compressing and sending a refrigerant at high temperature and high pressure as shown in FIG. 1, a main condenser 12 for condensing the refrigerant, and a subcool condenser ( 13, and the receiver 14, the expansion valve 15, and the evaporator 16.

That is, in the air conditioner system using the subcooled condenser 13, the high temperature and high pressure gaseous refrigerant discharged from the compressor 11 is liquefied while passing through the main condenser 12, and the liquefied refrigerant of the main condenser 12 While passing through the receiver dryer 17 installed on one side, only a part of the liquefied refrigerant is sent to the subcooler 13 to the receiver 14 while being liquefied once more.

In the receiver dryer 17 installed as described above, only the refrigerant in the completely liquid state passing through the filter 17a of the interruption can be sent to the subcooling condenser 13.

This can be seen that the cooling performance is improved because the effective liquid refrigerant is increased in the same amount of refrigerant, energy consumption is also reduced because the power consumption of the compressor is reduced by the improvement in cooling performance.

However, such a subcooling condenser should be sent to the subcooling zone only when the condensed refrigerant is liquefied, but when laid down, only the liquefied refrigerant cannot be sent to the subcooling zone.

For this reason, there is a problem that a subcooled capacitor cannot be used in an air conditioner system that is mounted in a vortex structure because it is possible only when the capacitor is installed by a standing type.

Therefore, the present invention has been made in view of the above-described conventional problems, the main object of the present invention is to provide a simple subcooled condenser condenser structure, more specifically, the refrigerant moving when the condenser is laid down The receiver subcooler is formed by forming a receiver dryer tank in which one side is raised so that it can be liquefied, and then pass through a filter and a desiccant in the part so that only the liquefied refrigerant can be supplied to the subcool zone. It's about making it available.

A characteristic configuration of the present invention for achieving the above object is a horizontally laid down left and right header pipes, a plurality of tubes arranged between the header pipes connected to the refrigerant flows, and filled between the tubes; A condenser for an air conditioner having a baffle at the stop of stopping the header pipe and configured to move a plurality of tubes in a zigzag manner after being configured as a cooling fin, wherein the condenser is attached to one side of the header pipe and has a downward ridge. A receiver dryer tank, a filter including a refrigerant desiccant while blocking the main body portion and the ridge of the receiver dryer tank, and fixed vertically in the ridge, the lower end of which is in the ridge and the upper end of the header. It is composed of vertical connecting pipes connected to be located in the subcool zone of the pipe.

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

Figure 2 is an external perspective view showing a subcooling capacitor of the present invention, Figure 3 is an enlarged perspective view of the main portion.

As shown in the figure, the condenser 20 includes left and right header pipes 21 and 22 lying horizontally, and a plurality of tubes 23 arranged to connect refrigerant between the header pipes, and After the cooling fins 24 are filled between the tubes, a baffle 25 is provided to stop the header pipes 21 and 22 so that the refrigerant moves the plurality of tubes 23 in a zigzag manner. . At this time, the part where the condensed refrigerant flows in the condenser 20 is the subcool zone 26.

In the present invention, the receiver dryer tank 27 is formed to be attached to the lower side of the header pipe 21 laid down horizontally, and connected to the through hole (21a), further extended from the main body portion (27a) to move downward in the shape of a plate It has a ridge 27b.

In the downwardly ridge 27b of the receiver dryer tank 27, a filter 28 including a refrigerant desiccant is provided while blocking the main body 27a and the ridge 27b.

In addition, the filter 28 is installed through the vertical connection pipe 29, the lower end is in the ridge 27b, the upper end is located in the sub-cool zone 26 of the header pipe 21 described above. Do it.

Here, it is preferable to form the seating portion 27c for the filter 28 and the support piece 27d on the inner surface of the downward ridge 27b to assemble the filter 28, and this filter 28 The size and shape of the part are not important in practicing the present invention.

In the figure, reference numeral 30 denotes a capacitor mounting bracket.

In the condenser of the present invention configured as described above, the refrigerant flows as shown in FIG.

That is, the refrigerant c that zigzags the plurality of tubes 23 by the baffles 25 provided in the both header pipes 21 and 22 is transferred to the receiver dryer tank 27 through the through holes 21a. Inflow.

In the receiver dryer tank 27, the liquefied refrigerant accumulates at the bottom of the raised portion 27b while passing through the filter 28 containing the desiccant.

The refrigerant accumulated in the ridge 27b is sent to the subcool zone 26 of the header pipe 21 through the vertical connection pipe 29.

The condenser of the present invention as described in detail above has a dish-shaped downwardly ridge attached to the bottom of the horizontally arranged header pipe and connected to the through hole so that the liquid refrigerant passing through the filter is accumulated. Since the connection is to be moved from the bottom portion of the ridge portion it is possible to move only the refrigerant completely changed to the liquid phase.

Therefore, it is possible to provide a wading subcooled condenser with a simple structure change, so that the cooling performance can be improved even in an air conditioning system that requires the use of the wading condenser, and it is possible to save the power consumption of the compressor according to the improvement of the cooling performance. Has an advantage.
