Description

Heat exchanger

The present invention relates to a heat exchanger, and provides a structure for physically and completely blocking the hot and cold parts in the heat exchanger by placing a partition wall for blocking between the hot and cold parts.

In general, a heat exchanger is a device for exchanging heat by directly or indirectly contacting two fluids having different temperatures, and having a passage part through which a heat exchange medium can flow, so that the heat exchange medium is separated from the outside air while the passage part flows. It is a device that enables heat exchange. Heat exchangers, which are devices that transfer heat from the hot part of a hot fluid to the cold part of a cold fluid to reduce the energy of the hot part fluid and increase the energy of the cold part fluid, are divided into various types according to the energy transfer method between the two fluids.

In the case of a heat exchanger system in which two fluids are separated so that only fluids are exchanged without mixing, there are plate heat exchangers, heat radiating tube heat exchangers, and tube heat exchangers.

Among them, a heat tube using a heat pipe (fin tube heat exchanger, hereinafter referred to as a "heat pipe heat exchanger") can be a heat transfer from the hot portion to the cold portion without requiring additional power, and contaminated Because it is easy to wash, etc., it is used as various types of heat transfer devices.

1 is a view showing a typical heat pipe heat exchanger, a plurality of individual tube 110 in the form of a heat pipe is installed in the heat exchanger frame 100, a plurality of heat dissipation fan 120 on the outer surface of each tube (110) ) Is provided. The heat source (air) transferred from the outside of the heat exchanger frame 100 while the predetermined refrigerant passes through the tube 110 exchanges heat with the refrigerant flowing through the tube 110 while passing through the tube 110 and the heat radiation fan 120. This is done.

This heat pipe heat exchanger may be used to perform heat exchange indoors. For example, when fresh cold air enters indoors through a heat exchanger, cold air passing through a heat exchanger frame may radiate heat from the tube 120. It is heat-exchanged with and provided in the room as warm air, and the warm air which is muddy in the room is discharged to the outside through the heat exchanger frame.

At this time, the fresh cold air (low temperature part) coming from the outside and the turbid warm air (high temperature part) coming from the room should not be mixed with each other in the heat pipe heat exchanger frame. However, when the tubes are arranged in a hexagonal or rectangular shape, which are advantageous for heat transfer due to the closely attached heat radiation fins, it is not easy to mechanically block the low and high temperatures in the heat exchanger. Therefore, there is an urgent need for a mechanical means that can easily shut off the cold and hot parts in the heat pipe heat exchanger.

The technical problem of the present invention is to block the low temperature portion and the high temperature portion from each other in the heat exchanger. In addition, the technical problem of the present invention is to provide a partition for physically blocking the low temperature portion and the high temperature portion in the heat exchanger. In addition, the technical problem of the present invention is to provide a structure for fastening the heat exchanger and the partition wall to each other.

A heat exchanger according to an embodiment of the present invention includes a train body for blocking a low temperature part and a high temperature part by including a tube through which a heat exchange refrigerant flows, a stopper provided on an outer circumferential surface of the tube, and a partition wall coupled with the stopper.

In addition, the heat exchanger is provided with a heat dissipation fin is installed on the outer peripheral surface of the tube at regular intervals.

The train body is formed with a partition plate through hole through which the tube and the heat radiation 휜 penetrate, a plate plate-shaped partition wall into which the tube is inserted into the partition wall through hole, and is installed in direct contact with an outer circumferential surface of the tube. It includes a stopper having an outer diameter larger than the diameter of the through hole so that the outer diameter does not pass through the partition wall through hole.

The stopper has a structure having a through hole on an inner surface thereof, and the tube is inserted into the through hole so that the inner diameter of the stopper penetrates the outer diameter of the tube and keeps airtightness.

According to an exemplary embodiment of the present invention, the low temperature part and the high temperature part of the heat exchanger may be separated and blocked through the partition wall. In addition, it is possible to prevent fluid mixing in the heat exchanger by using a partition structure, which is a physical device. In addition, even if the tube is arranged in a complicated hexagonal or rectangular shape, which is advantageous for heat transfer, the low temperature part and the high temperature part can be completely separated and blocked.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you. Like numbers refer to like elements in the figures.

2 is a perspective view illustrating the inside of a heat pipe heat exchanger according to an exemplary embodiment of the present invention.

The heat pipe heat exchanger allows the heat exchange medium to pass through the inside of the tube 110 in contact with the heat dissipation fan 120 to exchange heat with the flow air in contact with the surface of the tube 110 and the heat dissipation fan 120. have. Therefore, the arrangement structure of the tube 110 is designed so that heat exchange with the heat exchange medium passing therein can be well performed.

The tube 110 is provided in plurality in the form of a pipe extending to a predetermined length and a passage therein, and a heat exchange medium flows in each tube. The heat exchange medium is a fluid material, for example, that carries heat while changing state. Refers to the refrigerant. The outer surface of each tube 110 is provided with a plurality of heat dissipation fan (120). The heat dissipation fan 120 has a through hole through which the tube 110 penetrates, and the tube 110 is inserted through the through hole. The heat dissipation fan 120 has a polygonal structure such as a circle or a square having a plate of a predetermined thickness and area, and the heat exchange is made through the area of the heat dissipation fan by contacting the surface of the heat dissipation fan plate.

Meanwhile, the bent portion 121 of a predetermined length may be formed to protrude in a direction perpendicular to the surface of the heat dissipation fin as shown in FIG. The bent portion 121 protrudes a predetermined length in one direction from the through hole to maintain a constant distance between the neighboring heat radiating heat radiating heat radiating heat and at the same time to enlarge the contact area between the heat radiating heat and the tube to facilitate heat transfer. do. The bent portion 121 may be made by bending at the same time when the through hole of the heat radiation fin 120. Or it may be made of a separate apparatus attached.

In order to efficiently perform heat exchange between the tube 110 and the heat dissipation fan 120, the outer circumferential surface of the tube 110 and the bent portion 121 of the heat dissipation fan 120 should be contacted as closely as possible. To this end, by brazing the heat dissipation fins 120 and the tube 110 to weld them integrally, or by inserting the heat dissipation fins 120 into the tube 110, the tube 110 is expanded to increase the tube outer diameter. There is no gap between the tube 110 and the heat dissipation fan 120. When expanding, the material of the tube 110 is made of a relatively soft metal.

The heat pipe tube heat exchanger has the above structure, so that heat exchange (heat) transferred from the outside of the heat exchanger while a predetermined heat exchange medium (refrigerant) passes through the tube passes through the tube while passing between the heat radiating fans. Heat exchange with the medium takes place.

On the other hand, when performing the heat exchange in the room using the heat pipe heat exchanger, for example, when fresh cold air (cold mass) from the outside air enters the room through the heat exchanger, the outside cold air passing through the heat exchanger tube 110 The heat exchanger (120) is heated by the heat exchange medium (coolant) of the heat exchanger 120 is provided to the room as warm air. On the contrary, the air that is muddy in the room is discharged to the outside through a heat exchanger.

At this time, fresh cold air (low temperature part) coming from outside air and muddy warm air (high temperature part) introduced from the room should not be mixed with each other in the heat exchanger frame. To this end, an embodiment of the present invention is installed train body so that the fresh air of the outside air and turbid air of the indoor inflow is not mixed with each other. The train group consists of the partition wall 140 and the stopper 130.

The partition wall 140 has a plate plate structure to form a through hole (hereinafter, referred to as a 'bulk wall through hole') larger than the outer diameter of the heat dissipation fan 120 to insert the tube 110 into the partition wall through hole. . The diameter of the barrier rib through hole must be larger than the outer diameter of the heat dissipation fin 120 so that the heat dissipation fin 120 on the tube 110 and the tube outer circumferential surface can pass therethrough.

As the tube 110 and the heat dissipation fan 120 can penetrate the partition wall through-hole of the partition wall 140, the partition wall 140 may be positioned in the middle of the tube 110 in the longitudinal direction, thereby physically forming the low temperature part and the high temperature part. Can be separated.

Meanwhile, in order for the partition wall 140 to be installed in the tube 110 to physically separate the low temperature part and the high temperature part, the partition wall 140 must be fixed to the boundary line between the high temperature part and the low temperature part of the tube 110. By the way, since the diameter of the partition wall through-hole of the partition 140 is larger than the outer diameter of the heat dissipation fan 120, the tube 110 and the heat dissipation fan 120 can pass through the partition wall through-hole, and are physically partitioned. There is a need for a separate device to secure 140 to tube 110. Thus, the embodiment of the present invention has a structure in which the outer diameter of the specific heat dissipation fan of the tube 110 is formed larger than the diameter of the partition wall through-hole of the partition wall. The heat radiation 갖는 having an outer diameter formed larger than the diameter of the partition wall through-hole of the partition wall is hereinafter referred to as a stopper 130. For reference, FIG. 4 illustrates one stopper 130 formed on each of the plurality of tubes.

2 and 4, the stopper 130 is positioned on the outer circumferential surface of the tube 110. The stopper 130 is positioned at the boundary between the hot and cold portions, that is, at the boundary of the location where the partition wall 140 is to be installed.

The stopper 130 has the same structure as the heat dissipation fan 120, so that the tube 110 is inserted through the through hole formed in the stopper to be closely coupled to the tube 110. Combination of the tube 110 and the stopper 130, such as the coupling structure of the tube 110 and the heat dissipation fan 120, to weld the tube 110 and the stopper 130 integrally, or to the tube After inserting the stopper, expand the tube to increase the tube outer diameter so that there is no gap between the tube and the stopper.

According to an embodiment of the present invention, the stopper 110 is designed to have an outer diameter larger than the diameter of the partition wall through-hole of the partition wall 140, unlike the outer diameter of the heat radiation 휜. The heat dissipation fan 120 installed in the tube 110 may pass through the partition wall through-hole of the partition wall because its outer diameter is smaller than the diameter of the partition wall through-hole of the partition wall 140, but the stopper 130 is installed in the tube 110. Since the outer diameter of) is larger than the diameter of the partition through-hole of the partition 140, it cannot pass through the partition through-hole of the partition.

As a result, the embodiment of the present invention has a structure in which a stopper 130 having an outer diameter that does not pass through the partition wall through hole of the partition wall 140 is provided. Among the heat dissipation beams of the tube, a specific heat dissipation beam may have a larger outer diameter than the bulkhead through-hole of the partition wall to serve as a stopper. Alternatively, it may be implemented to install a partition by placing a separate stopper instead of a heat sink.

5 is a view showing a state in which the partition wall is installed in the tube, Figure 5 (a) is a view showing the state through which the tube is inserted into the partition wall, Figure 5 (b) of the tube inserted into the partition wall The figure shows the stopper not hanging on the bulkhead.

Referring to FIG. 5 (a), it can be seen that the heat dissipation fan 120 attached to the tube and the tube is inserted through the partition wall through hole of the partition wall 140. However, as the tube is inserted, the stopper 130 installed on the tube comes into contact with the partition wall, and the stopper 130 having an outer diameter larger than the partition wall through hole of the partition wall does not pass through the partition wall through hole and contacts the partition wall 140.

Therefore, by fixing the partition wall 140 to the stopper 130, as a result, it is possible to fix the partition wall on the tube.

Connection between the partition wall 140 and the stopper 130 may be made in various ways, for example, the partition wall 140 and the stopper 130 may be connected by a bolt tightening coupling. That is, the airtightness can be improved by making a screw receiving portion in the partition wall 140 and drilling a hole in the surface of the stopper 130 to tighten the bolt from the opposite side.

In addition, in order to further increase the airtightness of the partition wall 140 and the stopper 130, a gasket such as Viton, a copper alloy, epoxy, silicon, Teflon, or the like is formed in the boundary gap between the partition wall 140 and the stopper 130. The airtightness can be further improved by inserting into a -ring or a plate-shaped shield.

Meanwhile, the description of FIG. 5 illustrates an example in which one partition wall is installed in the tube, and a plurality of partition walls may be installed in the tube in order to increase the thermal barrier efficiency. That is, in order to more reliably block heat between the low temperature portion and the high temperature portion, it may have a structure in which partition walls are provided on both sides of the stopper.

6 is a view showing a state in which the partition is provided on both sides of the stopper according to an embodiment of the present invention. Referring to FIG. 6, the barrier ribs 140a and 140b are provided on the upper side and the lower side of the stopper 130, respectively, so that the low temperature part and the high temperature part having the barrier rib as a boundary may be more completely blocked.

When the barrier ribs are provided on both sides of the stopper as described above, as shown in FIG. 7, the barrier ribs and the barrier ribs may be directly bolted to increase the tightness between the barrier ribs. That is, in addition to the bolt tightening passing through the upper partition, the stopper and the lower partition, the bolt between the upper partition and the lower partition can be directly bolted in the region without the stopper.

On the other hand, since the number of tubes of the heat pipe heat exchanger is provided in a large amount, when the area size of the partition is large, the phenomenon that the center surface of the partition is struck may occur. In order to generate the deflection of the partition wall, a support for supporting the center surface of the partition wall in the housing frame of the heat pipe heat exchanger may be provided to distribute the load of the partition wall. Alternatively, in order to prevent sagging due to the load of the partition wall, the partition wall may have a structure in which a brace structure of a hard material is placed.

On the other hand, the plurality of tubes may be arranged in a variety of complex structures, such as rectangular, hexagonal, octagonal structure, etc., can be easily applied to the complicatedly arranged tubes when using the stopper and the partition according to an embodiment of the present invention. have.

On the other hand, although the embodiment of the present invention has been described as an example of a heat pipe heat exchanger, it will be apparent that it can be applied to various heat exchangers having only a tube without heat radiation such as a tube heat exchanger.

Although the invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the invention is not limited thereto, but is defined by the claims that follow. Accordingly, one of ordinary skill in the art may variously modify and modify the present invention without departing from the spirit of the following claims.
