Description

TECHNICAL FIELD [0001] The present invention relates to a microchannel type heat exchanger,

The present invention relates to a method of manufacturing a microchannel-type heat exchanger, and more particularly, to an apparatus and a method for manufacturing a microchannel-type heat exchanger which are capable of efficiently performing divided cooling without increasing the installation area of a condenser installed in a cooling apparatus, And more particularly, to a method of manufacturing a micro channel type heat exchanger.

2. Description of the Related Art Generally, a cooling device such as a refrigerator, a freezer, and an air conditioner includes a compressor that compresses a gaseous refrigerant into a high-temperature and high-pressure liquid state and provides a circulation force, and a condenser that condenses the compressed refrigerant in heat exchange A capillary tube for passing the condensed refrigerant through the capillary and phase-changing the refrigerant at a low temperature and a low pressure, and a heat exchanger (heat absorption) for passing the refrigerant at a low temperature and a low pressure through the condenser And a refrigerant cycle in which the refrigerant is sequentially circulated through an evaporator that is phase-changed into a gaseous state and returned to the compressor.

In the condenser, the condenser of each constituent of the refrigeration cycle is cooled while passing through the high-temperature high-pressure refrigerant sent from the compressor to the inside of the condenser, and is changed from the outlet of the condenser to the liquid refrigerant of low temperature and high pressure.

To this end, a conventional condenser includes a refrigerant tube through which a refrigerant flows, a radiating fin for radiating heat from the refrigerant tube, a header pipe installed at both ends of the refrigerant tube, and a high-temperature and high-pressure refrigerant flowing into the refrigerant tube And an outlet pipe which is installed so that the low-temperature and high-pressure liquid refrigerant condensed and liquefied in the refrigerant tube is discharged through the header pipe to the expansion tube.

However, as the types of the products to be stored in the cooling apparatus and the size of the internal space of the storage room have become various, it has become necessary to set the cooling temperatures of the respective storage rooms differently. The compression ratio of the compressor is required to be somewhat increased in order to set the temperature of the cooling chamber to a required temperature by using only one of the compressors. As a result, the energy consumption is increased due to the increase of the power consumption .

Further, a control device for controlling the operation of the compressor is installed separately in order to prevent an overload while the compressor is operated at a large compression ratio. In addition, there is a problem in that additional power loss and facility cost increase due to installation and operation of the control device .

Accordingly, as shown in FIG. 1, the refrigerant compressed in the first compressor 22 is supplied to the compressor 22, The first cooling cycle 21 which passes through the first capillary 25 via the first condenser 23 and then returns to the first compressor 22 via the first evaporator 26 of the dual pipe heat exchanger 2, And the refrigerant compressed in the second compressor 42 is passed through the oil separator 3 connected to one side of the second compressor by the oil separation pipe 4 and then passed through the second condenser 43 of the double pipe type heat exchanger 2 , And a second cooling cycle (41) in which the second capillary (45) and the second evaporator (46) are successively returned to the second compressor (42) A second oil separator 101 provided between the second capillary 45 and the second evaporator 46 and one end connected to the auxiliary oil separator and the other end connected between the second evaporator 46 and the second compressor 42, A low temperature refrigerator having a binary cooling cycle with a connected auxiliary oil collection tube 102 has been proposed.

However, the cooling efficiency can be expected to be improved through the two-way cooling cycle. On the other hand, there is a problem that the total energy consumption is increased to operate each of the binned cooling devices, There has been a problem that a cooling chamber at a portion where a cooling cycle is installed must be narrow or a whole size of the cooling device must be increased in order to provide a necessary space.

As shown in FIG. 2, the first compressor 31 and the first condenser 32, which constitute the first refrigeration cycle, The first expansion valve 33 and the cascade condenser 39 of the first refrigeration cycle and the second compressor 35 of the second refrigeration cycle and the second expansion valve 37, 2 evaporator 38 is installed inside the refrigerating device A. A third compressor 41, a cascade condenser 42, a third expansion valve 43 and a third evaporator 43 are connected to one side of the refrigerating device A, A second refrigerating device B connected to the second refrigerating device B by a refrigerant pipe so as to form a refrigerant cycle in the second refrigerating device B is provided at one side of the second refrigerating device B, and a fourth compressor 41, a cascade condenser 52, And a third refrigerating device C connected to the refrigerant pipe so that the valve 53 and the fourth evaporator 54 form a refrigeration cycle are provided in the multi-function multi-freezer system.

In this multi-function multi-freezer system, the refrigerant introduced into the cascade condensers 39, 42 and 52 from the first compressor 31 is supplied to the refrigerating apparatuses A, B, and C Compared with the prior art in which the refrigerating device is installed independently by effectively condensing the high temperature and high pressure refrigerant introduced from the compressors 35, 41, 51 into the cascade condensers 39, 42, 52, (B) and (C) can be connected and used at the same time through one high-pressure unit (3) comprising a first condenser (31) and a first condenser (32) The two-way refrigeration system using the cascade condensers 39, 42 and 52 can be applied to the intralums 2, 4 and 5 of the compressor C and the compressors 35, 41 and 51, (B) and (C), it is possible to use a compressor having a smaller capacity than the required refrigeration temperature.

However, in the conventional multipurpose multi-reservoir system, only one compressor 31 can be controlled to control a plurality of refrigerators A, B, and C, and the internal temperature of one refrigerator can be separately cooled The conventional problem that the internal space of the cooling chamber must be narrowed or the size of the cooling apparatus as a whole must be enlarged has not been improved since the condenser must be separately provided for each region to be cooled even if the multi-freezer system described above is applied.

Meanwhile, in recent years, in order to improve the overall energy efficiency by increasing the heat exchange efficiency of the condenser, the use of a heat exchanger having a microchannel-type refrigerant tube is increasing. Such a microchannel- The heat exchange efficiency of the refrigerant flowing inside the refrigerant tube is remarkably increased. Thus, it is possible to increase the heat exchange efficiency while reducing the installation area.

Korean Patent Laid-Open Publication No. 10-2014-0006681 (published on Jan. 16, 2014) discloses a refrigerating chamber evaporator which is produced by circulating one refrigerating cycle with one compressor and cooling the refrigerating chamber and the freezing chamber with different temperature ranges A heat exchanger for preventing a supercooling and waste of power consumption and a manufacturing method thereof have been proposed.

As shown in FIG. 3, the conventional heat exchanger includes a first compressor 32, a dual-pass condenser 101, a first condenser 101, a second condenser 101, In order to cool the first refrigerating device including the expansion valve 34, the first evaporator 35, the first blowing fan 37, and the first refrigerant pipe 36 and the second storage chamber used as the refrigerating chamber, A second refrigerant pipe 46, a second compressor 42, a dual-path condenser 101, a second expansion valve 44, a second evaporator 45, a second blower fan 47, 2 refrigerating apparatuses. In particular, the dual-path condenser 101, which is a device for condensing the refrigerant of the first refrigerating apparatus and the second refrigerating apparatus, is used in common.

4, the dual pass condenser 101 includes a plurality of headers 111 and 112 through which coolant flows, a laminated flat tube 121 which communicates between the plurality of headers 111 and 112, The first condensing passage 141 through which the first refrigerant passes and the second condensing passage 142 through which the second refrigerant passes are formed independently of each other, By condensing both the first refrigerant and the second refrigerant, space utilization and heat exchange efficiency can be increased.

However, the tube 121 used in the conventional dual-path condenser 101 is an integral flat tube having a plurality of channels, and the heat conducted to the tube 121 is effectively dissipated to the outside between the tubes 121 5, the area of the tube 121, that is, the air drawn into one side of the tube 121 and extended to the other side is formed to be long, even if the radiating fins 150 are joined in a zigzag shape , The residence time of the air is prolonged, and the heat exchange efficiency differs depending on the location of the tube 121 during the movement of the air, thereby lowering heat exchange efficiency.

Further, even in the process of moving the air along the air moving path provided by the tube 121 and the radiating fin 150, the air moving path is long and straight, and heat exchange through the radiating fin is not properly performed in the course of air movement There was a problem,

In the case where a plurality of cutting grooves are formed in the radiating fins to reduce the pitch interval of the radiating fins to increase the heat exchange efficiency while the air moves through the air moving path and to form turbulent flow while the air moves, Foreign matter such as foreign matter is caught in a narrow space or an incision groove of the air passage and eventually the air passage is obstructed and the heat exchange can not be performed properly.

In addition, since the radius of curvature of the bending portion is small in the process of bending the tube 121 in the 'r' shape, there is a problem in that a defective rate such as leakage of the refrigerant occurs, As the area of the tube 121 becomes wider, stable and easy assembly with the headers 111 and 112 must be formed in a square shape, so that the movement of the refrigerant smoothly is prevented compared to the circular headers 111 and 112, It became a problem to be inhibited.

In addition, the headers 111 and 112, the header caps 111d, 111e, 112d and 112e, the baffle 160, the tube 121 and the radiating fins 150 constituting the dual pass condenser 121 are all assembled by brazing The process of inserting the bent tube 121 into the header 111 or 112 and the process of disposing the radiating fin 150 between the bent tube 121 may be performed by friction or impact of each component. Therefore, the assembling process of the dual-path condenser 121 has to be manually performed, which lowers the production efficiency and increases the overall manufacturing cost due to labor costs.

Prior to the description, components having the same configuration are denoted by the same reference numerals as those in the first embodiment. In other embodiments, configurations different from those of the first embodiment will be described do.

Hereinafter, the micro channel type heat exchanger according to the first embodiment of the present invention will be described in detail with reference to FIGS.

The microchannel-type heat exchanger according to the first embodiment is connected to two first compressors (C1) and second compressors (C2) installed at one side of a cooling device to cool the divided cooling chambers to a predetermined temperature, A refrigerant tube 100, a radiating fin 200, a header pipe 300, an inlet pipe, and an outlet pipe.

The main components may be made of copper (Cu), but it is preferable that the main component is made of aluminum (Al) because the aluminum material is less expensive than the copper material and the manufacturing cost can be lowered. This is because it is easy and the heat exchange efficiency is good.

The refrigerant tube 100 is formed in a ring shape having a microchannel type, and the refrigerant tubes 100 having the same shape are arranged in a plurality of layers spaced from each other. Such a refrigerant tube 100 can shorten the residence time of the air It is preferable that the contact surface area is formed to have a width that enables effective cooling by air movement.

The radiating fins 200 are fixedly installed on opposite surfaces of the refrigerant tubes 100 spaced apart from each other, and have the same height and repeat shape such as corrugated or zigzag. 100, respectively.

In order to increase the heat exchange efficiency through the radiating fins 200, it is preferable that the pitch interval of the radiating fins 200 be narrow, but they should be formed at intervals allowing smooth movement of the air through the radiating fins 200.

At this time, a plurality of air flow portions 210 may be formed on each side of the radiating fin 200 so that air can move. When the air flow portion 210 is formed, So that the air moving through the air flowing unit 210 is moved in different directions to generate turbulence, thereby increasing the heat exchange efficiency .

The width of the radiating fin 200 may be equal to or greater than the width of the refrigerant tube 100. When the width of the radiating fin 200 is larger than that of the refrigerant tube 100, And may be coupled to the outer surface of the refrigerant tube 100 so as to protrude.

The header pipe 300 is connected to both ends of the refrigerant tube 100 and includes two different first header pipes 320 and second header pipes 330 connected to both ends of the refrigerant tube 100, Are partitioned into different discrete regions on both sides by the partition 310 coupled to a predetermined position.

Here, in order to divide the header pipe 300 into different separated regions, the partition 310 should be installed at the same height inside the first header pipe 320 and the second header pipe 330.

However, the inside of the first header pipe 320 partitioned by the partition 310 may be divided so that both sides have the same area, and the cooling chambers provided inside the cooling unit are formed in different areas, The first header pipe 320 and the second header pipe 320 may be divided into different areas so as to be cooled to different temperatures.

A first inlet pipe 321 connected to one side of the first header pipe 320 among the different header pipes 300 partitioned by the partition 310 as shown in FIG. A first outlet pipe 322 through which the refrigerant condensed and liquefied through the refrigerant tube 100 connected to one side of the first header pipe 320 is discharged; A first baffle 323 is provided to partition the inside of the first header pipe 320 so that a flow path to the outlet pipe 322 is formed.

A second inlet pipe 324 is connected to the other side of the first header pipe 320 so as to allow the refrigerant supplied from the second compressor C2 to flow therethrough and a second inlet pipe 324 connected to the other side of the first header pipe 320, A second outlet pipe 325 for discharging the refrigerant in a condensed and liquefied state via the first outlet pipe 321 and the second outlet pipe 325, And a second baffle 326 for partitioning the other side of the one header pipe 320 is installed.

One or more of the first baffle 323 and the second baffle 326 may be installed at one side or the other of the first header pipe 320 and the first header pipe 320 But also inside the second header pipe 330.

Since the first baffle 323 and the second baffle 326 are provided with the refrigerant flow path for moving the first header pipe 320 and the second header pipe 330, 320 and the second header pipe 330 so that the refrigerant can move through the first header pipe 320 and the second header pipe 330. The first header pipe 320 and the second header pipe 330 have the same height, 323 and the second baffle 326 are located on the same line, they function in the same manner as the partition 310 described above.

In other words, the first header pipe 320 and the second header pipe 330, which are divided into two different spaces by the partition 310 at both sides of the refrigerant tube 100, A first inlet pipe 321, a first outlet pipe 322 and a first baffle 323 are coupled to one side of the first header pipe 320, The second inlet pipe 325, and the second baffle 326 are combined to form a ring shape.

In this way, it is not necessary to separately provide installation spaces for the heat exchanger connected to the first compressor (C1) and the second compressor (C2) by dividing one heat exchanger main body (10) into two different regions It is possible to increase the space in which the cooling chambers of the cooling apparatus are provided and to separately operate the divided cooling zones when the cooling chambers of different sizes are cooled to the set temperatures, Energy consumption can be reduced.

On the other hand, on the opposite side, that is, on the opening side of the lowermost side refrigerant tube 100, there is provided an air outlet (not shown) A sealing member 500 for sealing the flow so as to be shut off is combined.

12, when the rotary fan 400 is installed in the main body 10 of the heat exchanger and the rotary fan 400 is operated in a state where the sealing member 500 is not coupled to the opposite side of the rotary fan 400, The air moves through the radiating fins 200 in the four chambers outside the main body 10 but more air moves at the opposite positions of the rotating fan 400 having a larger area than the radiating fins 200, The heat exchanging efficiency of the refrigerant moving through the rotary shaft 400 is lowered so that the sealing member 500 is coupled to the opposite side where the rotary fan 400 is installed so that the air moved by the rotary fan 400 passes through the radiating fins 200 It is preferable to increase the heat exchange efficiency.

By coupling the sealing member 500 to a part of the opened portion of the heat exchanger main body 10 as described above, the rotary fan 400 located on the opposite side as shown in FIG. 13 operates to suck air in the heat exchanger main body 10 The rotating fan 400 is moved to the inside of the heat exchanger main body 10 as shown in FIG. 14, so that the air outside the main body 10 of the heat exchanger 10 is uniformly sucked through four radiating fins 200, The air inside the main body 10 of the heat exchanger 10 is uniformly moved to the outside through the radiating fins 200 in four chambers by the rotation fan 400 The heat transfer of the refrigerant moving in the refrigerant tube 100 by the air moving through the radiating fin 200 can be performed more efficiently by allowing the moved air to be sucked or discharged only through the radiating fin 200. [

The material of the closure member 500 may be any one of a plate-shaped resin, a plate-like tributary, a plate-shaped wood, a plate-shaped metal, and a plate-shaped nonmetal material. Brackets, bolts, and the like.

The header pipes 300 connected to both ends of the refrigerant tube 100 are connected to the first header pipe 320 and the second header pipe 320 according to the degree of bending of the refrigerant tube 100 and the heat- The position of the header pipe 300 according to the first embodiment may be different from that of the first header pipe 320 and the second header pipe 330 as shown in FIG. They are overlapped and positioned to be shifted.

The position of the header pipe 300 according to the second embodiment of the present invention is such that the first header pipe 320 and the second header pipe 330 are closely aligned with each other along the longitudinal direction as shown in FIG. Lt; / RTI >

The position of the header pipe 300 according to the third embodiment of the present invention is such that the first header pipe 320 and the second header pipe 330 are overlapped with each other along the longitudinal direction as shown in FIG.

The position of the header pipe 300 according to the fourth embodiment of the present invention is such that the first header pipe 320 and the second header pipe 330 are spaced apart from each other as shown in FIG. The space S between the spaced portions is shielded by the finishing cover 600. This prevents the air sucked or discharged together with the operation of the rotating fan 400 from moving to the interspace S, The air is moved only through the radiating fins 200 in the four chambers of the main body 10, so that uniform heat exchange can be achieved.

10d, the first header pipe 320 and the second header pipe 330 are coupled to each other at the outer side of the heat exchanger main body 10, So that the spaced space S can be closed.

The reason why the first header pipe 320 and the second header pipe 330 are located at different positions as in the first to fourth embodiments is that, in the heat exchanger main body 10 of the same size, The size of the main body 10 of the heat exchanger 10 can be adjusted in response to a slight difference in the space area for installation of the heat exchanger in the cooling device.

In addition, the shape of the main body 10 of the heat exchanger may be any one of a circular shape, an elliptical shape, and a triangular shape or more as shown in FIGS. 10E to 10H because the heat exchanger So that the space form of the spot is different.

In addition, according to the first to fourth embodiments, the first inlet pipe 321, the first outlet pipe 322, The position where the second inlet pipe 324 and the second outlet pipe 325 are coupled to the first header pipe 320 is determined by the combination of the first inlet pipe 321 and the first compressor C1, The positions of the pipe 324 and the second compressor C2 should be considered in consideration of the combination of the pipe 324 and the second compressor C2.

As described above, the first header pipe 320 and the second header pipe 330 installed at both sides of one condenser are partitioned into different regions, and the inlet pipe into which the high temperature and high pressure gas refrigerant flows, The installation space of the condenser can be minimized and the usability of the installation space can be increased. As a result, it is possible to increase the efficiency of installation of the compressor The divided cooling for the supplied high-temperature and high-pressure gas refrigerant improves the condensing efficiency and the cooling efficiency and increases the energy efficiency due to the reduction in power consumption.

In the case where the heat exchanger connected to the first compressor (C1) and the second compressor (C2) is provided with two different bodies, it is necessary to perform two bending processes in order to manufacture the heat exchanger according to the present invention. Since the main body 10 has two different condensing and liquefying regions in one heat exchanger main body 10, it is possible to manufacture the main body 10 in a ring shape by a single bending process, There is an advantage that the production efficiency and convenience can be increased.

In addition, since the first header pipe 320 and the second header pipe 330 are positioned at different positions in a single bending process, various shapes corresponding to the shape of the space in which the heat exchanger is installed can be changed, There is an advantage that the usability of the installation space can be increased.

In addition, the contact surface area of the refrigerant tube 100 is widened to allow heat exchange within a short period of time, and the air and the air moving inside and outside the heat exchanger body through the radiating fins 200 coupled between the refrigerant tubes 100 The rotary fan 400 is installed on one side of the opening and the sealing member 500 is coupled to the opening on the opposite side so as to perform uniform heat exchange throughout the ring-shaped heat exchanger, The efficiency can be maximized.

A method of manufacturing a micro channel type heat exchanger as a heat exchanger material including the refrigerant tube 100, the radiating fin 200, and the header pipe 300 will be described in detail.

The refrigerant tube 100 is sequentially supplied by n heat exchanger lengths And a radiating fin 200 that has been subjected to a Clad process between the refrigerant tube 100 and the adjacent refrigerant tube 100 are sequentially inserted in the refrigerant tube 100, A step S4 of inserting a non-clad pressing force holding member 700 at each boundary point between the refrigerant tubes 100 and 100, a step S5 of assembling the header pipes 300 at both ends of the refrigerant tubes 100, (S6) of brazing the heat exchanger material, removing the pressing force holding member 700 (S7), forming the heat exchanger in n pieces To the header pipe step (S8) for cutting (300), made of an individual heat the cut pieces n, including the step (S9) for bending in a ring shape.

At this time, before cleaning the one side of the header pipe 300, cleaning the surface of the refrigerant tube 100, the radiating fin 200, and the header pipe 300 forming the heat exchanger, or removing the oxide layer And then flux coating each of the refrigerant tube 100, the radiating fin 200, the header pipe 300, and the pressing force holding member 700 may be further performed.

The step S1 of cutting one side of the header pipe 300 includes a partition 310 separating the internal space of the header pipe 300 into different regions on both sides by using a compression processing machine such as a press, 310 to separate the first baffle 323 and the second baffle 326 to form a flow path through which the refrigerant flows.

The step S4 of inserting the radiating fins and the pressing force holding member is performed by inserting the radiating fin 200 having been subjected to the Clad treatment between the refrigerant tube 100 and the refrigerant tube 100, The non-clad pressing force holding member 700, which is not subjected to the cladding, is inserted into the opposing face between the upper and lower refrigerant tubes 100 and 100. The pressing force holding member 700 is not subjected to the cladding treatment Even though the step S6 of brazing the heat exchanger material after the header pipe 300 is assembled, the surfaces of the refrigerant tubes supported by the pressing force holding member 700 are not subjected to the brazing process , And then cutting the header pipe 300 into n pieces (S8), so that n heat exchangers separated from each other can be manufactured.

In addition, the step S5 of assembling the header pipe 300 joins both ends of the refrigerant tube 100 to the insertion hole formed on the other side of the header pipe 300, Should be formed to have a length corresponding to the length of the refrigerant tubes 100 continuously supplied by n heat exchanger lengths to be manufactured at one time.

Here, the step S8 of cutting the header pipe 300 to manufacture the n heat exchangers from the step S3 of sequentially supplying the refrigerant tubes 100 is described in a patent application No. 10-1540071 , A method for manufacturing an air conditioner condenser).

In addition to the advantage that a plurality of heat exchangers having a flat plate shape can be collectively manufactured through the manufacturing method according to this patent, the header pipe 300 is divided into two different regions for each of n heat exchangers. By adding the step S1 of cutting one side of the pipe 300 and the step S2 of assembling the partition 310 and the first baffle 323 and the second baffle 326, It is possible to manufacture a large number of heat exchangers in which two heat exchange regions can be formed in the heat exchanger of the present invention, thereby reducing manufacturing costs due to mass production and improvement in production efficiency.

In addition, by adding a step S9 of bending a flat plate heat exchanger made of n pieces into a ring shape, it is possible to increase the utilization efficiency of the installation space as shown in FIG. 6 and to improve the heat exchange efficiency remarkably, Type heat exchanger can be manufactured.

As described above, since the conventional heat exchanger main body is processed every unit and the transfer interval generated is eliminated, a plurality of heat exchangers can be produced at the same time, so that the convenience of work is increased and the productivity is improved. The manufacturing cost can be reduced through mass production.
