It consists of a lower door 3 hinged to (1).

Further, a machine room 4 is formed below the main body 1, and the machine room 4 is equipped with a compressor 5 for compressing a refrigerant at high temperature and high pressure.

In addition, a condenser 6 for condensing the refrigerant compressed at high temperature and high pressure in the compressor 5 is disposed at the rear of the main body 1, and the condenser 6 is configured to generate cold air at the rear of the freezing chamber 1b. Evaporator 7 is installed to evaporate the refrigerant condensed in.

In such a refrigerator, the refrigerant is compressed to high temperature and high pressure in the compressor 5, and the high temperature and high pressure refrigerant compressed by the compressor 5 is supplied to the condenser 6 to be heat-exchanged with indoor air to form a liquid refrigerant. The refrigerant converted in phase conversion in the condenser 6 is introduced into a pressure reducer (not shown).

In addition, the reduced pressure refrigerant is supplied to the evaporator (7) to absorb heat from the ambient air by the evaporation action of the refrigerant to generate cold air, the cold air generated in the evaporator (7) by the cooling fan (8) The foods supplied to the freezer compartment 1b and the refrigerating compartment 1c and stored in the freezer compartment 1b and the refrigerating compartment 1c are freshly stored.

In such a refrigerator, the refrigerant compressed by the compressor (5) is not only high pressure but also a high temperature state of about 70-90 ° C, and maintains about 45 ° C even higher than room temperature or room temperature even in the condenser (6) having a heat exchange function. Done.

The effective heat dissipation of the compressor 5 and the condenser 6 in a high temperature state is closely related to the power consumption of the refrigerator. In the related art, a blower fan is installed around the compressor to promote heat dissipation of the compressor. The condenser was installed on the rear wall of the refrigerator body to perform heat dissipation by natural convection.

That is, the heat around the compressor was normally radiated by the forced convection method by driving the blower fan, and the heat of the condenser was radiated by the natural convection method.

In addition, the condenser has a problem that the heat dissipation effect is very low because the heat dissipation is performed by natural convection.

In particular, since the refrigerator is disposed close to a wall of a home or office, there is a problem that the air flow in this part is not desired, and heat radiation by natural convection in the condenser is extremely low.

In addition, a high voltage generator 60 is applied to the machine room 20 to apply voltage to the first electrode and the second electrode so as to generate a corona discharge by applying a voltage to the first electrode and the second electrode, which will be described later. ) Is installed.

In addition, the upper and lower side walls 11, 12, both side walls 13, and the rear wall 14 forming the main body 10 are foamed and filled by the field foaming between the outer shell of the metal material and the inner shell of the plastic injection molding. The first wall 30 is disposed on the rear wall 14 to generate a corona wind by applying a voltage generated from the high voltage generator 60.

In addition, the first electrode 30 may be attached to an outer surface of the rear wall 14 via an insulating material or an outer box may be used as the first electrode 30. In this embodiment, the outer box may be used as the first electrode ( 30).

In addition, the outer surface of the rear wall 14 serving as the first electrode 30 and the outer walls of the upper and lower side walls 11 and 12 and the both side walls 13 should be insulated by the insulating material 30a.

The second electrode structure 40 is spaced apart from the first electrode 30 at a rear side of the first electrode 30.

In addition, the second electrode structure 40 is disposed above the cover 22, and both sides thereof are disposed in contact with the protrusion 13 ′ protruding from the main body 10.

In addition, the second electrode structure 40 may be formed such that a space is formed between the plate-shaped second electrode 41 positioned opposite to the first electrode 30 and the second electrode 41. An outer body 42 disposed outside the second electrode 41 and a heat insulating material 43 filled in a space between the outer body 42 and the second electrode 41.

In addition, an insulating material 44 is attached or coated to the protrusion 13 ′ and the outer body 42 which are in contact with the second electrode 41.

In addition, the condenser 50 for condensing the refrigerant is a pipe disposed in a coil shape inside the second electrode structure 40, and an end thereof is connected to the refrigerant pipe of the main body 10. It is.

Meanwhile, as shown in FIGS. 2 and 3, the first electrode 30 and the second electrode are disposed between the first electrode 30 and the second electrode 41 of the second electrode structure 40. A flow passage 70 for guiding the corona wind upward so that the corona wind generated by the 41 heats the condenser 50 is formed.

Next, the effect of the heat dissipation device of the condenser according to the present invention configured as described above will be described.

When a voltage is applied from the high voltage generator 60 to the first electrode 30 and the second electrode 41, corona wind is generated from the surface of the first electrode 30 toward the surface of the second electrode 41. The corona wind flows upward along the flow passage 70 to promote heat dissipation of the condenser 50 installed in the second electrode structure 40.

That is, when a voltage of several kv generated from the high voltage generator 60 is applied to the first electrode 30 and the second electrode 41, the first electrode 30 to the second electrode ( 41) electric field lines are formed and corona discharge is caused by using the air between them as an insulating layer. At this time, the oxygen molecules around the first electrode 30 is ionized by electrons generated in a large amount from the first electrode 30 and is anionized so that particles in the air are charged with a negative charge, thereby forming the first along the electric force line. As it moves in the direction of the second electrode 41, a corona wind is generated between the two electrodes.

In addition, since the corona wind has a speed of 1 to 2 m / s and consumes less than 1 watt of power, the conventional corona wind has a speed of less than 0.5 m / s at the piping surface of the hot condenser pipe at the rear of the refrigerator in a conventional refrigerator. The heat dissipation and heat exchange effect is superior to convection.

In addition, the corona wind generated from the first electrode 30 and the second electrode 41 is along the flow passage 70 formed between the first electrode 30 and the second electrode 41.
