Description

heat pipe heat exchanger

[0001] The present invention relates to a heat pipe heat exchanger, and more specifically, to a heat pipe heat exchanger that exchanges heat between a high-temperature section and a low-temperature section using a variable assembly type heat pipe.

[0002] Typically, a heat exchanger is a device that exchanges heat by bringing two fluids of different temperatures into direct or indirect contact. Such heat exchangers are classified into various types depending on the method of energy transfer between the two fluids.

[0003] Among the various types of heat exchangers, plate heat exchangers, finned-tube heat exchangers, and tube heat exchangers are designed to separate heat exchange fluids to prevent mixing and exchange only energy.

[0004] In particular, fin tube heat exchangers (hereinafter referred to as "heat pipe heat exchangers") utilizing heat pipes are used as various types of heat transfer devices because they do not require additional power, can achieve heat transfer from a high-temperature section to a low-temperature section, and are easy to clean in case of contamination.

[0005] Figure 1 illustrates an example of a conventional heat pipe heat exchanger (1). As illustrated, when heat exchange is performed using the heat pipe heat exchanger (1), a high-temperature fluid (HT) is introduced into the high-temperature chamber (4a) of the high-temperature section (4), heats the heat pipe (2), and is then discharged outside the high-temperature chamber (4a). Additionally, a low-temperature fluid (LT) that passes through the low-temperature chamber (3a) of the low-temperature section (3) installed above the high-temperature section (4) is discharged outside the low-temperature chamber (3a) after heat exchange with the heat pipe (2).

[0006] Here, in order to prevent the high-temperature fluid (HT) flowing into the high-temperature chamber (4a) and the low-temperature fluid (LT) flowing into the low-temperature chamber (3a) from mixing with each other, a separator plate (5) is installed between the high-temperature section (4) and the low-temperature section (3).

[0007] In the conventional heat pipe heat exchanger (1) as described above, as shown in FIG. 2, the heat pipe (2) is combined with heat dissipation fins (2a) to expand the heat exchange area.

[0008] However, since the heat pipe (2) combined with the conventional heat dissipation fin (2a) and separator plate (5) corresponds to the size of the heat exchanger (1), its length cannot be adjusted. Consequently, there was a problem in that the heat pipe (2) used for a heat exchanger (1) of a different size could not be reused for another heat exchanger (1) after manufacturing and using the heat pipe (2) corresponding to the size of the heat exchanger (1).

[0009] The background of the present invention is disclosed in Korean Published Patent No. 10-2016-0138720 (Title of Invention: Modular Heat Exchanger).

[0010] The present invention was created to solve the above-mentioned problems, and aims to provide a heat pipe heat exchanger in which a variable assembly type heat pipe of the heat transfer section, which transfers heat from a high-temperature section to a low-temperature section, can be simply assembled to fit the size of the heat exchanger, and the length of the variable assembly type heat pipe can be adjusted to correspond to the size of the heat exchanger.

[0011] To achieve the above objectives, the present invention provides a heat pipe heat exchanger comprising: a high-temperature section having a high-temperature chamber into which a high-temperature fluid is introduced and discharged; a low-temperature section having a low-temperature chamber into which a low-temperature fluid is introduced and discharged; and a heat exchange section having a plurality of variable assembly type heat pipes installed between the high-temperature section and the low-temperature section to partition the high-temperature section and transfer heat from the high-temperature section to the low-temperature section for heat exchange.

[0012] In a heat pipe heat exchanger according to the present invention, the heat exchanger may include a plurality of first variable assembly type heat pipes spaced apart and a plurality of second variable assembly type heat pipes disposed between the first variable assembly type heat pipes spaced apart and coupled with the first variable assembly type heat pipes.

[0013] Each first variable assembly type heat pipe may include a first high-temperature bellows disposed in the high-temperature portion, a first low-temperature bellows connected to one end of the first high-temperature bellows and disposed in the low-temperature portion, and a first separation plate mounted between the first high-temperature bellows and the first low-temperature bellows and partitioning the high-temperature portion and the low-temperature portion, and a first mounting hole formed in the center of the first separation plate for mounting the first high-temperature bellows and the first low-temperature bellows, and the first separation plate may be provided with a plurality of snap pins protruding upward for coupling with a plurality of second variable assembly type heat pipes.

[0014] Each second variable assembly type heat pipe may include a second high-temperature bellows disposed in the high-temperature portion, a second low-temperature bellows connected to one end of the second high-temperature bellows and disposed in the low-temperature portion, and a second separation plate mounted between the second high-temperature bellows and the second low-temperature bellows and partitioning the high-temperature portion and the low-temperature portion, wherein a second mounting hole in which the second high-temperature bellows and the second low-temperature bellows are mounted may be formed in the center of the second separation plate, and a plurality of coupling holes coupled with a plurality of snap pins may be formed in the second separation plate.

[0015] The first separation plate may have a rectangular shape, and a plurality of snap pins may be formed on the periphery of the first separation plate; the second separation plate may have a rectangular shape, and a coupling end may be formed to protrude outwardly on the periphery, and the coupling hole may be formed in the coupling end.

[0016] According to the heat pipe heat exchanger of the present invention, a variable assembly type heat pipe that transfers heat from a high-temperature section to a low-temperature section can be easily assembled, and thus the size of the heat exchange section can be easily adjusted to fit the size of the heat exchanger.

[0017] In addition, since the variable assembly heat pipe has a bellows structure, the length of the variable assembly heat pipe can be easily adjusted in accordance with the size of the heat exchanger, and the variable assembly heat pipe can be used regardless of the size of the heat exchanger.

[0026] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0027] Referring to FIGS. 3 and 4, a heat pipe heat exchanger (100) according to an embodiment of the present invention includes a high temperature section (H), a low temperature section (L), and a heat exchange section (1000). A high temperature chamber (HR) is formed in the high temperature section (H), and a high temperature fluid (HT), such as hot gas, is introduced into and out of the high temperature chamber (HR).

[0028] A low-temperature chamber (LR) is formed in the above low-temperature section (L), and a low-temperature fluid (LT), such as water, flows into and out of this low-temperature chamber (LR).

[0029] A heat exchanger (1000) is installed between the high-temperature section (H) and the low-temperature section (L), and the heat exchanger (1000) partitions the high-temperature section (H) and the low-temperature section (L) and transfers heat from the high-temperature section (H) to the low-temperature section (L) to perform heat exchange.

[0030] The heat exchanger (1000) comprises a plurality of first variable assembly type heat pipes (1100) and a plurality of second variable assembly type heat pipes (1200). A plurality of the first variable assembly type heat pipes (1100) are spaced apart, and a plurality of the second variable assembly type heat pipes (1200) are spaced apart and combined with the first variable assembly type heat pipes (1100). By adjusting the number of combined first variable assembly type heat pipes (1100) and second variable assembly type heat pipes (1200) to match the size of the heat exchanger, the size of the heat exchanger (1000) can be easily adjusted.

[0031] Referring to FIGS. 3 and FIGS. 5, each of the first variable assembly type heat pipes (1100) includes a first high-temperature bellows (1110), a first low-temperature bellows (1120), and a first separation plate (1130).

[0032] It is preferable that the first high-temperature bellows (1110) is placed in the high-temperature section (H) and the first low-temperature bellows (1120) is placed in the low-temperature section (L), and that one end of the first high-temperature bellows (1110) and one end of the first low-temperature bellows (1120) are connected so that the first high-temperature bellows (1110) and the first low-temperature bellows (1120) are in communication.

[0033] It is preferable that the first separation plate (1130) be mounted between the connected first high-temperature bellows (1110) and the first low-temperature bellows (1120), and the high-temperature portion (H) and the low-temperature portion (L) are partitioned by the first separation plate (1130). Since the structure in which the first separation plate (1130) is mounted between the first high-temperature bellows (1110) and the first low-temperature bellows (1120) is general, a detailed description thereof will be omitted.

[0034] The first separation plate (1130) has a rectangular shape, and a first mounting hole (1131) is formed in the center of the first separation plate (1130) to which the first high-temperature bellows (1110) and the first low-temperature bellows (1120) are mounted, and a plurality of snap pins (1132) are provided on the periphery of the first separation plate (1130) to protrude upward, and are coupled to the second variable assembly type heat pipe (1200) by the plurality of snap pins (1132).

[0035] Referring to FIGS. 3, 6 and 7, each of the second variable assembly type heat pipes (1200) includes a second high-temperature bellows (1210), a second low-temperature bellows (1220), and a second separation plate (1230).

[0036] It is preferable that the second high-temperature bellows (1210) is placed in the high-temperature section (H) and the second low-temperature bellows (1220) is placed in the low-temperature section (L), and that one end of the second high-temperature bellows (1210) and one end of the second low-temperature bellows (1220) are connected so that the second high-temperature bellows (1210) and the second low-temperature bellows (1220) are in communication.

[0037] It is preferable that the second separation plate (1230) be mounted between the connected second high-temperature bellows (1210) and the second low-temperature bellows (1220), and the high-temperature portion (H) and the low-temperature portion (L) are partitioned by the first separation plate (1130). Since the structure in which the second separation plate (1230) is mounted between the second high-temperature bellows (1210) and the second low-temperature bellows (1220) is general, a detailed description thereof will be omitted.

[0038] The second separation plate (1230) has a rectangular shape, and a connecting end (1230a) is formed to protrude outwardly on its periphery. A second mounting hole (1231) is formed in the center of the second separation plate (1230) to which the second high-temperature bellows (1210) and the second low-temperature bellows (1220) are mounted. A connecting hole (1232) is formed on the periphery of the second separation plate (1230) to which the snap pin (1132) of the first separation plate (1130) is connected. It is preferable that the connecting hole (1232) be formed on the connecting end (1230a).

[0039] When the first variable assembly type heat pipe (1100) and the second variable assembly type heat pipe (1200) are combined, the first separation plate (1130) and the second separation plate (1230) are not positioned on the same line, and the second separation plate (1230) is positioned so as to be in close contact with the upper part of the first separation plate (1130). The snap pin (1132) provided on the circumferential surface of the first separation plate (1130) is inserted into the coupling hole (1232) formed on the circumferential surface of the second separation plate (1230), thereby combining the first variable assembly type heat pipe (1100) and the second variable assembly type heat pipe (1200). By pulling out the snap pin (1132) from the coupling hole (1232), the first variable assembly type heat pipe (1100) and the second variable assembly type The connection of the heat pipe (1200) is released.

[0040] By simply combining or uncombining the plurality of first variable assembled heat pipes (1100) and the plurality of second variable assembled heat pipes (1200), if each of the first variable assembled heat pipes (1100) and second variable assembled heat pipes (1200) fails to perform its function due to failure, the faulty first variable assembled heat pipe (1100) or second variable assembled heat pipe (1200) can be easily replaced, making maintenance easy, and the size of the heat exchanger (1000) can be easily adjusted in accordance with the size of the heat exchanger.

[0041] Referring to FIGS. 8 and 9, the first variable assembled heat pipe (1100) and the second variable assembled heat pipe (1200) have a bellows structure, so the first variable assembled heat pipe (1100) and the second variable assembled heat pipe (1200) can be extended and compressed to a desired length, thereby allowing the height of the heat exchanger (1000) to be easily adjusted according to the situation.

[0042] The first variable assembly type heat pipe (1100) and the second variable assembly type heat pipe (1200), which transfer heat from the high temperature part (H) to the low temperature part (L), can be easily assembled, so the size of the heat exchange part (1000) can be easily adjusted to fit the size of the heat exchanger.

[0043] In addition, since the first variable assembly type heat pipe (1100) and the second variable assembly type heat pipe (1200) have a bellows structure, their lengths can be easily adjusted to correspond to the size of the heat exchanger, and because the lengths can be adjusted, they can be used without being constrained by the size of the heat exchanger.

[0044] The present invention has been described with reference to embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.

[0045] The present invention can be used in a heat pipe heat exchanger.
