The plate fin 130 may be directly coupled to the refrigerant pipe 110 to be configured to absorb heat of the refrigerant passing through the refrigerant pipe 110.

The plate pin 130 may include an upper plate pin 134 and a lower plate pin 132.

The lower plate pin 132 may include a recess 133 to correspond to the outer circumferential surface of the refrigerant pipe 110 so that the refrigerant pipe 110 may be inserted along the path.

The recess 133 may be provided to correspond to both the heat dissipation tube 113 and the bending tube 114, but is provided to correspond to the heat dissipation tube 113 in the embodiment of the present invention. Therefore, at least two recesses 133 may be provided to correspond to the heat dissipation tube 113 along the first direction W1.

When the main refrigerant pipe 112 is inserted into the groove 133, the upper portion may be covered by the upper plate pin 134. One surface of the upper plate pin 134 may be provided to cover the lower plate pin 132 together with the recess 133 into which the main refrigerant pipe 112 is inserted.

The inner plate portion 134a and the outer plate portion 132a may have the same configuration as the upper plate pin 134 and the lower plate pin 132, respectively.

As described above, the same outer plate portion 132a as the lower plate pin 132 has a recess 133 to surround at least a part of the main refrigerant pipe 112, and an inner plate portion that is the same as the upper plate pin 134. 134a may be provided to contact the outer plate portion 132a and cover the recess 133.

An edge where the 144 meets may be referred to as the ridge 148 and the valley 146.

Although the first wave surface 142 and the second wave surface 144 may be formed in a plane, it is preferable that the first wave surface 142 and the second wave surface 144 be formed to be bent as in the embodiment of the present invention to increase the heat dissipation area.

The wave fins 140 are provided in a shape in which the peaks 148 and the valleys 146 are bent so as to be repeated, the peaks 148 are lower portions of the lower plate pins 132, and the valleys 146 are upper plate pins 134. It may be provided to contact the back of each.

In detail, the ridge 148 and the valley 146 may be provided to be repeatedly arranged a plurality of times along the first direction W1 in which the heat dissipation tube 113 is wound. That is, the hill 148 and the valley 146 may be provided in a second direction W2 perpendicular to the first direction W1.

The peak portion 148 and the valley portion 146 of the wave fin 140 are provided in the second direction W2 perpendicular to the first direction W1, and the refrigerant pipe 110 provided in the first direction W1. This is to allow the wave fin 140 to be wound while the hill 148 and the valley 146 are maintained while being wound in the vertical direction of the plate pin 130.

In addition, the air passing through the wave fins 140 through the blower fan 56 may be guided through the peaks 148 and the valleys 146 of the wave fins 140 through the configuration of the heat dissipation pipe 113. Since the direction perpendicular to the longitudinal direction can improve the blowing efficiency, it is possible to concentrate the air blown between the wave fin 140 and the plate fin 130 can improve the heat dissipation efficiency.

The condenser 100 may be made of a material having high thermal conductivity in consideration of heat radiation efficiency. In particular, the refrigerant pipe 110 and the plate fin 130 may include an aluminum material.

The condenser 100 may be assembled by brazing joining all the components to prevent leakage of the refrigerant. That is, the coolant pipe 110, the plate fin 130 and the wave fin 140 may be coated with a clad material for brazing bonding.

Accordingly, the coolant pipe 110 is seated in the recess 133 of the lower plate pin 132, covered with the upper plate pin 134, and the wave pin 140 is disposed on one surface of the upper plate pin 134. After the condenser 100 can be assembled into the brazing furnace.

The prefabricated condenser 100 is approximately 600? When heated to a temperature of from 700 to 700? The cladding material coated on each component is melted, and the joints of the components are sealed and firmly bonded at the same time. Therefore, the joints of the respective components may be formed to have a somewhat gap so that the clad material melts to seal the spaced gaps.

The structure of the condenser 100 according to the embodiment of the present invention is not merely applied to the condenser 100, but may be applicable to the evaporator 40 as a heat exchanger, and may be applied to an air conditioner as well as a refrigerator. Of course.

As a result, the heat dissipation efficiency of the plurality of refrigeration cycles can be improved in the limited machine room 50, and the energy consumed for the heat dissipation can be reduced.

The condenser 100 including the refrigerant pipe 110 and the heat dissipation part 120 may have a cylindrical shape by winding the plate fin 130 in a direction surrounding the wave fin 140.

That is, the heat dissipation tube 113 may be wound in a vertical direction of the plate fin 130 with respect to the first direction W1 in which the heat dissipation tube 113 is disposed. In detail, the lower plate fin 132 surrounds the condenser 100. It can be rolled up to be placed outside.

The cylindrical shape may be formed in a cylindrical shape dried in various forms such as a cylindrical pillar shape as well as a cylindrical shape.

In order to arrange the miniaturized condenser 100 in a limited space in the machine room 50, the heat dissipation efficiency of the condenser 100 should be improved.

In the wound tubular condenser 100 using the pipe-shaped refrigerant pipe 110 instead of the tubular refrigerant pipe 110, the space between the plate fin 130 and the plate fin 130, the wave fin 140 is It is made up of arrangements to be arranged. By using the pipe-like refrigerant pipe 110 through such a configuration, it is advantageous to control the flow of the refrigerant, and also to enable a uniform distribution of the refrigerant, between the plate fin 130 and the plate fin 130 Even in the space of the heat radiation by the wave fins 140 may have an improved heat dissipation effect.

Hereinafter, the refrigerant flow of the condenser 100 having the above configuration and the refrigerator having the same will be described.

8 is a view showing a refrigerant flow of the condenser 100 according to an embodiment of the present invention. Arrows in the figure indicate the flow of refrigerant.

Since the flow of the refrigerant due to the configuration of the compressor 10, the condenser 100, the expansion valve 30, and the evaporator 40 has been described above, the description thereof will be omitted, and the flow of the refrigerant in the condenser 100 will be described.

First, the refrigerant flowing into the inlet portion 116 passes through the heat dissipation tube 113 disposed on the first virtual surface P1. Thereafter, the heat dissipation tube disposed on the second virtual surface P2 via the bent tube 114 connecting the heat dissipation tube 113 on the first virtual surface P1 and the heat dissipation tube 113 on the second virtual surface P2. 113 flows, and the heat radiation tube 113 on the 3rd virtual surface P3 flows through the bending pipe 114 connected to the heat radiation tube 113 on the 2nd virtual surface P2. The refrigerant flowing up to the heat dissipating tube 113 on the fourth virtual surface P4 flows out through the outlet part 118 and passes through the expansion valve 30.

In this process, the heat dissipation tube 113 primarily transfers heat to the lower plate fin 132 and the upper plate fin 134 surrounding the wave, and is secondly provided to contact the upper plate fin 134. The heat is transferred to the pin 140. In this heat transfer process, heat may be discharged to the outside of the condenser 100 by the flow of air passing through the side of the condenser 100.

By disposing the wave fins 140 between the plate fins 130 and the plate fins 130, the heat dissipation area becomes wider. Therefore, the heat dissipation efficiency is improved and miniaturization is possible even in the case of having the same heat dissipation amount.

In the above, specific embodiments have been illustrated and described. However, the present invention is not limited to the above embodiments, and those skilled in the art may make various changes without departing from the spirit of the invention as set forth in the claims below. .
