In addition, LP, HP, and OP shown in the drawings represent a low pressure gauge, a high pressure gauge and a flexible meter, respectively, OPS represents a hydraulic protection switch, HPS represents a high pressure switch, and HLPS represents a high / low pressure switch, respectively.

Referring to the cooling process by the air-cooled condenser according to the prior art configured as described above are as follows.

Here, only the cooling process by the air-cooled condenser will be described, but the operation of the air-cooled condenser used in the refrigeration, refrigeration, air conditioning operation is similar to the operation, of course, it can be widely applied.

First, when the refrigerant compressed in a gaseous state of high temperature / high pressure by the compressor 10 is introduced into the condenser 20 through the refrigerant pipe, the condenser 20 delivers the gaseous refrigerant compressed by high temperature / high pressure to the cooling fan. It heat-exchanges as air blown by and forcibly cools the said refrigerant to liquefy.

Thereafter, the high pressure refrigerant liquefied in the condenser 20 checks the state of the refrigerant while passing through the receiver 30 and the filter 40 and removes impurities contained in the refrigerant.

The high pressure refrigerant from which impurities are removed through the above process is provided to the evaporator 70, wherein the refrigerant coexists with gas and liquid of low / low pressure while passing through an expansion valve 60 which expands to the evaporation pressure of the refrigerant. Is converted into a refrigerant, and flows into the evaporator 70 in that state.

Thereafter, the refrigerant introduced into the evaporator 70 takes heat from the air blown by the indoor fan by the vaporization of the evaporator 70 to cool the indoor air, and discharges the cooled air into the room to cool the air. The low temperature / low pressure gas refrigerant converted by the evaporator 70 is sucked back into the compressor 10 to repeat the above process.

However, the air-cooled condenser according to the prior art is applied to the refrigeration, refrigeration, air conditioning by performing a heat exchange process only with the air blown by the cooling fan during the liquefaction of the high-temperature / high-pressure gas refrigerant compressed in the compressor If the indoor space is large, the cooling fan for heat exchange needs to have a larger capacity and size in proportion to the space. Therefore, a space for installing the cooling fan is required, and thus a loss of power cost is increased. There was a problem that the maintenance cost is increased.

In addition, when the air-cooled condenser is applied to perform refrigeration, refrigeration, and air conditioning, the temperature of the liquefied refrigerant discharged from the air-cooled condenser is higher than a required temperature, thereby causing another problem of lowering cooling efficiency.

Therefore, the present invention was devised to solve the above problems, and its purpose is to inject a heat medium having a high heat transfer rate to the outside of the copper pipe when the high temperature / high pressure refrigerant discharged from the air-cooled condenser moves through the copper pipe. And providing a heat-pipe cooler at a predetermined position in the upper portion of the air-cooled condenser to convert the temperature of the refrigerant into a cooled state by a predetermined temperature by evaporation and condensation of the heat medium.

The cooling process of the air-cooled condenser having the heat-pipe cooler configured as described above is as follows.

First, the air-cooled condenser 100 that receives the high temperature / high pressure refrigerant from the compressor 250 performs a heat exchange operation with air blown by a plurality of cooling fans, thereby forcibly cooling the high temperature / high pressure refrigerant to liquefy, The liquefied high temperature / high pressure refrigerant is provided to the first copper pipe 114 of the thermal medium pipe 112.

The provided high temperature / high pressure refrigerant flows along the inside of the first copper pipe 114. In this case, a predetermined amount of heat medium H, for example, a freon gas, is injected into a space in a vacuum state in the heat medium tube 112. When heat is applied in one state, the refrigerant performs a heat exchange operation according to the evaporation operation of the heat medium (H).

From this state, the heat medium (H) in the evaporated heat medium tube (112) flows into the second copper pipe (118) of the cooling member (116) having a wicking process and has a suction function at the same speed as the speed of sound. Then, the heat medium (H) present in the second copper pipe 118 is condensed by the temperature is lowered in the heat dissipation of the aluminum fin 120 and heat exchange with the outside air, the condensed heat medium (H) Is returned to the heat medium tube (112).

As described above, when the heat medium H repeatedly moves between the heat medium pipe 112 and the cooling member 116 in an evaporation and condensation operation, the refrigerant temperature flowing in the first copper pipe 114 is also lowered by a predetermined temperature.

For example, according to the repeated heat exchange operation, the refrigerant temperature discharged from the heat-pipe cooler is discharged to about 43 ° C to 45 ° C (summer basis), which is cooled by about 5 ° C rather than the refrigerant temperature discharged from the air-cooled condenser 100. do.

Thereafter, the coolant discharged in the cooled state is supplied to the receiver 200, and the refrigerant discharged through the receiver 200 is freed of impurities and filtered through the filter 210 and the expansion valve 230. After the expansion to the evaporation pressure of the supplied to the evaporator 240, the evaporator 240 is a heat exchange with the air blown by the indoor fan to cool the indoor air, the low-temperature / low-pressure gaseous refrigerant in the compressor ( 250).

By the refrigerant cycle as described above, the refrigerant is repeatedly circulated and operated.

According to the above embodiment, it can be seen that the refrigerant temperature discharged from the heat-pipe cooler is provided to the receiver and the evaporator as being cooled by a predetermined temperature rather than the refrigerant temperature of the air-cooled condenser to improve the cooling effect.

In addition, although the embodiments of the present invention have been described and illustrated above, it is possible to be variously modified / implemented by those skilled in the art by being applied to all the air-cooled condensers that liquefy the refrigerant by air-cooling in a refrigeration, refrigeration, or air conditioning apparatus using the refrigerant. It is obvious that such embodiments are to be modified within the scope of the appended claims.

As described in detail above, the air-cooled condenser having a heat-pipe condenser according to the present invention is a heat exchanger that does not rely only on a cooling fan having a large volume and a high power ratio, but a small volume and does not require separate power. Since the refrigerant temperature is lowered by the pipe cooler, the size of the air-cooled condenser can be miniaturized, thereby reducing the cost and reducing the power and cost.
