Description

Heat Radiating mechanism for Refrigerator of machine room}

The present invention relates to a refrigerator, and more particularly to a refrigerator having improved structure of a machine room while adding a cooling fan that operates independently of a conventionally used cooling fan to efficiently cool a condenser and a compressor installed in the machine room. It relates to a machine room cooling structure.

In general, a refrigerator is a refrigeration and refrigerating device in which the inside of the refrigerator is cooled by repeating a refrigeration cycle in which the refrigerant is compressed, condensed, expanded, and evaporated to keep food fresh for a long time.

In order to perform the refrigeration cycle of the refrigerator, there is shown a cooling structure of a conventional refrigerator machine room in which a compressor for compressing a low-temperature low-pressure refrigerant into a high-temperature high-pressure refrigerant and a condenser for exchanging the refrigerant passing through the compressor with external air are shown. Referring to 1, it is as follows.

A compressor 3 is installed at one side of the inside of the machine room, and a condenser 4 for discharging a large amount of heat is provided at the side of the compressor 3, and at the side of the condenser 1, the refrigerator machine room ( 1) A cooling fan 9 for cooling the heat generated inside, in particular, the heat generated by the condenser 4 by forced air is axially coupled to the motor 10.

In addition, the suction unit 5 and the air discharge unit 7 and 6 in which a plurality of suction ports are formed to protect the devices outside the refrigerator machine room 1 and to cool the inside of the refrigerator machine room 1 smoothly. The machine room cover 2 is formed.

The air outlets 7 and 6 are provided at the side of the compressor 3 so as to discharge air sent to the compressor 3 via the first outlet 6 and the condenser 4 located on the side of the condenser. (7)

Accordingly, while the refrigerator is being driven, heat is generated as the compressor 3 and the condenser 4 installed inside the refrigerator machine room 1 are operated, and at the same time, the cooling fan 9 according to the driving of the motor 10 is performed. By the rotation of the air is introduced into the machine room through the suction unit 5, the air sucked by the cooling fan 9 is sent to the condenser 4 to dissipate the heat generated in the condenser (4).

In this way, the air passing through the condenser 4 is partially discharged through the first discharge part 6, and the remaining air is continuously sucked toward the compressor 3 to dissipate heat of the compressor 3 while the compressor 3 is discharged. It is discharged through the second discharge part 7 located in the side part.

The refrigerator machine room configured as described above cools the compressor together with a condenser that dissipates a large amount of heat with one cooling fan, thereby reducing cooling efficiency. In order to solve the problem, the refrigerator machine room vibrates as the size of the cooling fan increases or the number of rotations increases. There is a problem that the noise and increase.

In addition, since the cooling fan is located at one side of the condenser, the air passing through the condenser is heated and is not suitable for cooling the compressor, thereby lowering the compression efficiency of the compressor and increasing power consumption.

In addition, since the high temperature air discharged from the first discharge part in front of the condenser is re-absorbed through the suction part, there is a problem of lowering the heat exchange rate of the condenser by the cooling fan.

The present invention has been made to solve the problems of the prior art, by improving the cooling structure of the refrigerator machine room to increase the cooling efficiency of each component inside the machine room, and to increase the compression efficiency and condensation efficiency through the cooling efficiency It is an object of the present invention to provide a refrigerator machine room cooling structure that can reduce noise generated in a cooling fan.

In order to achieve the above object, the present invention is a refrigerator machine room equipped with a compressor and a condenser, a plurality of cooling fans installed on each side of the compressor and the condenser to cool the compressor and the condenser, and between the compressor and the condenser in the refrigerator machine room And installed in the space so as to partition the space in which the compressor and the condenser are installed, and the air supplied from the cooling fan installed at the side of the compressor among the cooling fans is configured to be guided out of the refrigerator machine room through the compressor. The air supplied from the cooling fan installed on the side of the condenser is composed of a blowing guide member formed to pass through the condenser to be guided out of the refrigerator machine room, and a cover in which a plurality of intake and exhaust mechanisms are formed to intake and exhaust the air.

Referring to the configuration as described above with reference to the drawings as follows.

3 is a front view showing a refrigerator machine room structure according to the present invention, Figure 4 is a cross-sectional view showing a first embodiment of the refrigerator machine room structure according to the present invention, Figure 5 is a second embodiment of the refrigerator machine room structure according to the present invention It is a cross-sectional view which showed the example.

As shown in FIG. 3, the compressor 3 and the condenser 4 are installed at the center of the refrigerator machine room 1 at regular intervals, and the first cooling fan 23 dissipates heat of the condenser 4. And a first fan motor 24 driving the first cooling fan 23 are installed at one side of the condenser 4, and the second cooling fan 26 and the first cooling fan 26 are also provided at one side of the compressor 3. The second fan motor 25 for driving) is installed.

In addition, the compressor (3) is installed on the bottom surface of the refrigerator machine room (1) by a support made of the anti-vibration rubber (8) to insulate the vibration generated in itself.

In addition, the cover 2 may include a plurality of first suction parts 20 and a plurality of suction ports formed on the side surfaces of each of the cooling fans 23 and 26 such that the cooling fans 23 and 26 suck external air. 2 The inlet part 21 and the outlet part 22 formed with a plurality of outlets located on the side of the condenser 4 and the compressor 3 are heat-exchanged in the condenser 4 and the compressor 3 to be discharged to the outside. Include.

That is, the cover 2 has two suction parts 21 and 20 located at both sides, and a discharge part 22 having a plurality of discharge ports is provided at the center thereof.

In addition, the outlet 22 is not formed only on the side of the condenser 4, but is formed in the center of the cover 2 across the compressor 3 and the condenser 4 side so that the outlet 22 and the suction part 20, 21) the gap between them becomes wider.

On the other hand, as shown in Figure 4, by the cooling fans (23, 26) installed on both sides of the refrigerator machine room (1) so that the air to the compressor (3) and the condenser (4) does not interfere with each other ( 1) A blowing guide member 30 which divides the interior into separate spaces for the compressor 3 and the condenser 4 is installed between the compressor 3 and the condenser 4.

In addition, the blowing guide member 30 guides the air sucked by the cooling fans 23 and 26 installed at one side of the compressor 3 and the condenser 4 to the compressor 3 and the condenser 4. An inclined surface 31 and a blocking wall for guiding each air delivered along the inclined surface 31 to be heat-exchanged in the compressor 3 and the condenser 4 to be discharged to the outlet 22 in the center of the cover 2. 32 is extended to the inclined surface 31 is formed in the center of the blowing guide member 30.

In addition, the inclined surface 31 of the blowing guide member 30 is formed in a curve having a constant internal curvature radius so as to secure a space for the compressor 3 and the condenser 4 without widening the inside of the refrigerator machine room 1. do.

In addition, the blowing guide member 30 has both the compressor 3 and the condenser 4 without the blocking wall 32 formed at the center of the blower guide member 30 completely blocking the compressor 3 and the condenser 4. It is formed so that there is a space enough to exchange air with each other.

On the other hand, the blowing guide member for completely blocking between the compressor (3) and the condenser (4) so that the cooling of the compressor (3) is not hindered by the condenser (4) that generates more heat than the compressor (3) A second embodiment in which 40) is installed is as follows.

That is, as shown in Figure 5, the blocking wall 42 of the blowing guide member 40 completely blocks the compressor 3 and the condenser 4 in a separate space inside the machine room to the side of each of the compressor and condenser Cooling only by the cooling fans (23, 26) installed in.

The rest of the configuration is the same as in the first embodiment.

On the other hand, the blowing guide member (30, 40) has a symmetrical structure on both sides with respect to the center, or the length of the inclined surface (31, 31b) is different depending on the space occupied by the compressor (3) and the condenser (4) It may be asymmetrical.

And, if there is room in the refrigerator machine room, it can be formed in a straight line that is easy to manufacture the inclined surface of the blowing guide member.

Referring to the operation of the present invention configured as described above are as follows.

Since the cooling fans 23 and 26 are separately installed in the compressor 3 and the condenser 4, the cooling fans installed on the sides of the compressor and the condenser according to the heat generated by the compressor 3 and the condenser 4 ( 23, 24) to control the effective cooling.

That is, conventionally, since the compressor is also cooled by the air passing through the condenser, there is a limit in increasing the amount of air by increasing the rotation speed of the cooling fan provided with only the condenser.

Thus, as described above, a second cooling fan 26 for the compressor 3 is provided to cool the compressor 3 without being affected by the condenser 4.

In addition, since the first cooling fan 23 for the condenser 4 only needs to add air enough to cool the condenser 4, the condenser (1) does not increase the rotation speed of the first cooling fan 23 unduly. According to the state of 4), efficient cooling is performed.

In addition, since two air intakes 20 and 21 are formed in the cover 2 in correspondence with the respective cooling fans 23 and 36, a large amount of air is sucked in a short time so that the compressor 3 and By cooling the condenser 4, the cooling effect is increased.

Meanwhile, the air applied by the first cooling fan 23 and the second cooling fan 26 is smoothly guided to the compressor 3 and the condenser 4 by the blowing guide members 30 and 40 installed at the center of the machine room, respectively. Heat exchange takes place.

In particular, the air is discharged to the outside through the discharge portion 22 of the cover 2 without interfering with the air by the blocking walls (32, 42) of the blowing guide member (30, 40).

On the other hand, in the case where the compressor 3 and the condenser 4 are completely blocked as in the second embodiment, cooling is more effectively performed when the refrigerator is enlarged and the heat generated in the condenser is increased and the capacity of the compressor is also increased. .

As described above, the present invention can reduce the noise caused by the cooling fan because it is not necessary to increase the rotation speed of the cooling fan to increase the cooling effect.

In addition, the cooling efficiency of the compressor is reduced by the condenser, thereby increasing the compression efficiency of the compressor which consumes the most electric power in the refrigerator, thereby reducing the consumption strategy of the refrigerator.

On the other hand, unlike the cover of the conventional refrigerator machine room, because the gap between the outlet and the suction portion is wide, it is possible to reduce the amount of re-suction of the discharged air, the plurality of the suction portion is formed by a relatively large amount of air sucked in the compressor The cooling time of the condenser is also shortened.

In addition, since the configuration of the present invention can be added without significantly modifying the structure of the conventional refrigerator machine room, it is possible to manufacture a refrigerator having improved performance by using a conventional refrigerator as well as reducing the refrigerator manufacturing cost.
