Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to a heat exchange module in the form of a Freon heat pipe. Background Technology

[0002] A Freon heat pipe heat exchange module is a heat exchanger based on the principle of heat pipes. It generally consists of two sets of heat exchange plates: an evaporator plate and a condenser plate. The heat exchange plates are filled with a working medium, which includes both liquid and gaseous components. When the medium on the evaporator plate is heated, its temperature rises and it vaporizes into a gaseous state, which is then transferred to the condenser plate. After releasing heat in the condenser plate, it re-liquefies into a liquid state and returns to the evaporator plate due to gravity, forming a cycle.

[0003] However, in existing technologies, the connection between the evaporator plate and the condenser plate usually requires a relatively long connecting pipe. The rising connecting pipe needs to cross the low-level manifold of the condenser plate and connect to the high-level manifolds of both the evaporator and condenser plates for upward transport of the heat exchange medium after vaporization. The returning connecting pipe, on the other hand, needs to cross the high-level manifold of the evaporator plate and connect to the low-level manifolds of both the evaporator and condenser plates for downward return of the heat exchange medium after liquefaction. This increases the length of the connecting pipe, the structural complexity and equipment cost, and also increases the possibility of the connecting pipe being damaged by collisions. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a heat exchange module in the form of a Freon heat pipe.

[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used:

[0006] A heat exchange module in the form of a Freon heat pipe includes an evaporator plate and a condenser plate arranged at different heights. The evaporator plate is lower than the condenser plate and includes a first manifold at a higher position and a second manifold at a lower position. The condenser plate includes a third manifold at a higher position and a fourth manifold at a lower position. Flat tubes are connected between the first and second manifolds, and between the third and fourth manifolds. A reflux structure for connecting the first and third manifolds is provided on a first side plate on one side of the evaporator plate, and a rising structure for connecting the second and fourth manifolds is provided on a second side plate on one side of the condenser plate.

[0007] The Freon heat pipe heat exchange module of this invention mainly consists of two parts: an evaporator plate and a condenser plate. The evaporator plate is lower than the condenser plate. The heat exchange medium in the evaporator plate evaporates from a liquid state to a gaseous state after absorbing heat. The heat exchange medium in the condenser plate condenses from a gaseous state to a liquid state after releasing heat. The condenser plate and the evaporator plate are connected by a reflux structure and a rising structure. The rising structure is used to allow the gaseous heat exchange medium to enter the condenser plate from the evaporator plate, and the reflux structure is used to return the reliquefied liquid heat exchange medium from the condenser plate to the evaporator plate, thus forming a cycle and enabling continuous heat exchange. Of course, the third manifold is higher than the second manifold. The upward or downward flow of the heat exchange medium is driven by density difference and gravity. Moreover, the reflux structure and the rising structure are partially set on the side plate, which is beneficial to the simplification of the structure.

[0008] In the above-mentioned Freon heat pipe heat exchange module, the reflux structure includes a reflux connecting pipe connecting the second manifold and the third manifold, and a reflux channel disposed in the first side plate. One end of the reflux channel is connected to the manifold cavity of the first manifold, and the other end is connected to the reflux connecting pipe through the reflux transition zone of the second manifold.

[0009] The upper end of the reflux connecting pipe is connected to the collection chamber of the third manifold, and the other end is connected to the reflux transition zone separated in the second manifold. This reflux transition zone is relatively short and is not connected to the flat tube; it is only used for the reflux transition of the heat exchange medium. First side plates are respectively provided on both sides of the evaporator plate to ensure the structural strength of the connection between the first and second manifolds and to protect the flat tube between them. Notably, a reflux channel is formed within one of the first side plates, connecting the reflux transition zone and the first manifold. From the perspective of the overall reflux structure, the exothermic liquefied heat exchange medium flows into the third manifold, and then sequentially passes through the reflux connecting pipe, the reflux transition zone, and the reflux channel back to the first manifold, ensuring that the heat exchange medium of the condenser plate smoothly returns to the evaporator plate after exothermic liquefaction.

[0010] In the aforementioned Freon heat pipe heat exchange module, a baffle is provided at one end of the second manifold. The baffle is located between the reflux channel and the flat tube of the evaporator plate, and a reflux transition zone is formed between the baffle and the inner end face of the second manifold. The first side plate near the reflux transition zone is hollow, forming an axially penetrating reflux channel. Both ends of the reflux connecting pipe are connected to the evaporator plate and the condenser plate respectively through an integral brazing structure. The first side plate is welded and fixed to the evaporator plate, providing the reflux channel and serving as a protective plate for the evaporator plate.

[0011] A baffle plate is placed horizontally inside the second manifold, perpendicular to its length, dividing the manifold's interior into a reflux transition zone and a collection chamber. The end of the flat tube connects to the collection chamber, which collects the gaseous heat exchange medium evaporated in the evaporator plate and transports it to the condenser plate. The reflux channel of the first side plate is achieved through a hollow structure. The cross-section of the first side plate is preferably square; however, the other side's first side plate is typically a long strip. The first side plate serves both a basic protective function and a connection between the first and second manifolds, offering multiple functions.

[0012] In the above-mentioned Freon heat pipe heat exchange module, the rising structure includes a rising connecting pipe connecting the second manifold and the third manifold, and a rising channel disposed in the second side plate. One end of the rising channel is connected to the manifold cavity of the fourth manifold, and the other end is connected to the rising connecting pipe through the rising transition zone of the third manifold.

[0013] The rising structure is similar to the reflux structure, and the specific structure will not be explained in detail. For the rising structure, the heat exchange medium located in the flat tube of the first manifold and the evaporator plate vaporizes after absorbing heat. Due to the decrease in density, the gaseous heat exchange medium rises and enters the manifold cavity of the second manifold. Then, it passes through the rising connecting pipe, the rising transition zone and the rising channel in sequence to enter the fourth manifold and fill the flat tube of the condenser plate, ensuring that the heat exchange medium of the evaporator plate rises smoothly into the condenser plate after vaporization.

[0014] In the aforementioned Freon heat pipe heat exchange module, a baffle is provided at one end of the third manifold. The baffle is located between the rising channel and the flat tube of the condensing plate, and the rising transition zone is formed between the baffle and the inner end face of the second manifold. The second side plate near the rising transition zone is hollow inside, forming an axially penetrating rising channel. The two ends of the rising connecting pipe are respectively connected to the evaporating plate and the condensing plate through an integral brazing structure. The second side plate is welded and fixed to the condensing plate, providing the rising channel and serving as a protective plate for the condensing plate.

[0015] The formation of the rising transition zone is similar to that of the reflux transition zone, so it will not be described in detail here.

[0016] In the above-mentioned Freon heat pipe heat exchange module, the second and third manifolds are provided with partition insertion holes that penetrate the pipe wall. The partition is inserted into the second or third manifold through the partition insertion holes and fixed, dividing the manifold into an upward transition zone or a return transition zone.

[0017] The partition plate is inserted into the manifold through the partition plate insertion hole, which is simple to process and assemble. After insertion, it can be fixed by welding or other methods, ensuring airtightness. Furthermore, the partition plate includes a circular plate body with a circumferentially extending and radially protruding snap-fit ​​arc edge on its side wall. The snap-fit ​​arc edge is precisely engaged in the partition plate insertion hole, and the snap-fit ​​arc edge and its extension length are exactly a semicircle. The side wall of the circular plate body away from the snap-fit ​​arc edge is in close contact with the inner wall of the manifold, and the snap-fit ​​arc edge is welded and fixed to the partition plate insertion hole.

[0018] In the above-mentioned Freon heat pipe heat exchange module, the first manifold is provided with a filling pipe that communicates with the manifold cavity. The filling pipe is located inside the protective cover, and the protective cover is detachably fixed to the first manifold.

[0019] The filling pipe is used to fill the heat exchange medium. Since the heat exchange medium generally does not need to be replaced frequently after filling, a protective cover can effectively protect the filling pipe.

[0020] In the above-mentioned Freon heat pipe heat exchange module, h-shaped fixing seats are provided on the first manifold and / or the second manifold, as well as on the third manifold and / or the fourth manifold.

[0021] Auxiliary fixing plates are provided on the return connection pipe of the return structure and the rise connection pipe of the rise structure. The auxiliary fixing plates are sleeved on the return connection pipe or the rise connection pipe through the connection through hole.

[0022] The aforementioned rising structure and reflux structure are distributed at both ends of the arrangement direction of the flat tube group.

[0023] The mounting base is used to fix the evaporator plate and the condenser plate. It can be provided with holes or grooves for bolts to pass through. The auxiliary fixing plate is sleeved on the connecting pipe, which can position the connecting pipe to a certain extent and prevent the connecting pipe from being bent.

[0024] In the above-mentioned Freon heat pipe heat exchange module, the second manifold and the third manifold are connected by a connecting pipe. The connecting pipe is provided with a multi-angle connection structure with the second manifold and / or the third manifold, which enables the evaporator plate and the condenser plate to be connected and fixed at different angles. The third manifold is not lower than the second manifold.

[0025] The connecting pipe includes a return connecting pipe with a return structure and a rise connecting pipe with a rise structure. The connecting pipe is connected to the corresponding manifold through a multi-angle connecting structure. The multi-angle connecting structure allows the connection angle between the connecting pipe and the corresponding manifold to be selected as needed, so that there are multiple options for the angle between the evaporator plate and the condenser plate, which can adapt to different installation environments.

[0026] In the aforementioned Freon heat pipe heat exchange module, the multi-angle connection structure includes a connecting seat disposed on the second or third manifold. The connecting seat communicates with the interior of the second or third manifold through the opening of the manifold. The connecting seat is provided with several circumferentially distributed connecting parts. The inner end of the connecting part communicates with the opening of the manifold, and the outer end is closed by a plug or connected to a connecting pipe.

[0027] The inner end of the connector is connected to the opening of the manifold, while the outer end is provided with multiple tubular connecting parts. The connecting tube can be inserted into one of the connecting parts for connection, and the remaining free connecting parts are closed by plugs. The distribution direction of the multiple connecting parts is adapted to the radial surface of the manifold, so that the connecting tube can have a variety of angle schemes relative to the condenser plate or evaporator plate.

[0028] Compared with the prior art, the present invention has the following main advantages:

[0029] 1. The condenser plate and the evaporator plate are connected by a reflux structure and a rising structure. The rising structure is used to allow the gaseous heat exchange medium to enter the condenser plate from the evaporator plate, while the reflux structure is used to return the reliquefied liquid heat exchange medium from the condenser plate to the evaporator plate, thus forming a cycle that enables continuous heat exchange. The upward or downward flow of the heat exchange medium is driven by density difference and gravity. Moreover, the reflux structure and the rising structure are partially set on the side plate, which helps to simplify the structure.

[0030] 2. This heat exchanger consists of a condenser plate, an evaporator plate, and two connecting pipes forming a heat circulation channel, and has a simple structure.

[0031] 3. The baffle is inserted into the manifold through the baffle insertion hole. The processing and assembly are simple. After being inserted into place, it can be fixed by welding or other methods, which also ensures the airtightness.

[0032] 4. The connecting pipe is connected to the corresponding manifold through a multi-angle connection structure, so that the connection angle between the connecting pipe and the corresponding manifold can be selected as needed, thus providing multiple options for the angle between the evaporator plate and the condenser plate to adapt to different installation environments.

Detailed Implementation

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] Example 1

[0043] Specific implementation examples Figures 1-5 As shown, the heat exchange module of this Freon heat pipe type includes an evaporator plate 2 and a condenser plate 1 arranged at different heights. The evaporator plate 2 is lower than the condenser plate 1 and includes a first manifold 3 located at a higher position and a second manifold 4 located at a lower position. The condenser plate 1 includes a third manifold 5 located at a higher position and a fourth manifold 6 located at a lower position. Flat tubes 7 are connected between the first manifold 3 and the second manifold 4, and between the third manifold 5 and the fourth manifold 6. A reflux structure 9 for connecting the first manifold 3 and the third manifold 5 is provided on the first side plate 8 on one side of the evaporator plate 2. A rising structure 11 for connecting the second manifold 4 and the fourth manifold 6 is provided on the second side plate 10 on one side of the condenser plate 1.

[0044] Specifically, the Freon heat pipe heat exchange module mainly consists of two parts: an evaporator plate 2 and a condenser plate 1. The rising structure 11 is used to allow the gaseous heat exchange medium to enter the condenser plate 1 from the evaporator plate 2, while the reflux structure 9 is used to return the reliquefied liquid heat exchange medium from the condenser plate 1 to the evaporator plate 2, thus forming a cycle and enabling continuous heat exchange. The upward or downward flow of the heat exchange medium is driven by density difference and gravity. Moreover, the reflux structure 9 and the rising structure 11 are partially set on the side plate, which is beneficial to the simplification of the structure.

[0045] like Figure 1 , Figure 4 As shown, the reflux structure 9 includes a reflux connecting pipe 12 connecting the second manifold 4 and the third manifold 5, and a reflux channel 13 disposed within the first side plate 8. One end of the reflux channel 13 is connected to the manifold cavity of the first manifold 3, and the other end is connected to the reflux connecting pipe 12 through the reflux transition zone 15 of the second manifold 4. One end of the second manifold 4 is provided with a baffle 16, which is located between the reflux channel 13 and the flat tube 7 of the evaporation plate 2. A reflux transition zone 15 is formed between the baffle 16 and the inner end face of the second manifold 4. The first side plate 8 near the reflux transition zone 15 is hollow, forming an axially penetrating reflux channel 13. Both ends of the reflux connecting pipe 12 are integrally brazed to the second manifold 4 and the third manifold 5, respectively. Both ends of the first side plate 8 are welded and fixed to the outer walls of the first manifold 3 and the second manifold 4, respectively.

[0046] Specifically, the upper end of the reflux connecting pipe 12 is connected to the collection cavity of the third collector pipe 5, and the other end is connected to the reflux transition zone 15 separated in the second collector pipe 4. The reflux transition zone 15 is relatively short and is not connected to the flat tube 7. It is only used for the reflux transition of the heat exchange medium. The two sides of the evaporator plate 2 are respectively provided with first side plates 8 to ensure the structural strength of the connection between the first collector pipe 3 and the second collector pipe 4, and also to protect the flat tube 7 between them. In particular, a reflux channel 13 is also formed in one of the first side plates 8. The reflux channel 13 connects the reflux transition zone 15 and the first collector pipe 3. From the perspective of the reflux structure 9 as a whole, the heat exchange medium that is liquefied by heat release flows into the third collector pipe 5, and then passes through the reflux connecting pipe 12, the reflux transition zone 15 and the reflux channel 13 in sequence to return to the first collector pipe 3, ensuring that the heat exchange medium of the condenser plate 1 flows smoothly back to the evaporator plate 2 after being liquefied by heat release. The partition 16 is placed horizontally in the second manifold 4 perpendicular to the length direction, dividing the inner cavity of the manifold 4 into two parts: the reflux transition zone 15 and the manifold cavity. The end of the flat tube 7 is connected to the manifold cavity. The manifold cavity can collect the gaseous heat exchange medium that has been heated and evaporated in the evaporation plate 2 and transport it to the condenser plate 1. The reflux channel 13 of the first side plate 8 is realized through a hollow structure. The cross-section of the first side plate 8 is square. Of course, the first side plate 8 on the other side is a general long strip plate.

[0047] like Figure 1 , Figure 3 As shown, the rising structure 11 includes a rising connecting pipe 17 connecting the second manifold 4 and the third manifold 5, and a rising channel 18 disposed within the second side plate 10. One end of the rising channel 18 is connected to the manifold cavity of the fourth manifold 6, and the other end is connected to the rising connecting pipe 17 through the rising transition zone 19 of the third manifold 5. One end of the third manifold 5 is provided with a baffle 16, which is located between the rising channel 18 and the flat tube 7 of the condenser plate 1. The baffle 16 and the inner end face of the second manifold 4 form a rising transition zone 19. The interior of the second side plate 10 near the rising transition zone 19 is hollow, forming an axially penetrating rising channel 18. Both ends of the rising connecting pipe 17 are integrally brazed to the second manifold 4 and the third manifold 5, respectively. Both ends of the second side plate 10 are welded and fixed to the outer walls of the third manifold 5 and the fourth manifold 6, respectively.

[0048] Specifically, the rising structure 11 is similar to the reflux structure 9. The heat exchange medium located in the flat tube 7 of the first collector tube 3 and the evaporator plate 2 vaporizes after absorbing heat. Due to the decrease in density, the gaseous heat exchange medium rises and enters the collection cavity of the second collector tube 4. Then, it passes through the rising connecting pipe 17, the rising transition zone 19 and the rising channel 18 in sequence to enter the fourth collector tube 6 and fill the flat tube 7 of the condenser plate 1, ensuring that the heat exchange medium of the evaporator plate 2 rises smoothly into the condenser plate 1 after vaporization.

[0049] like Figures 3-5 As shown, the second manifold 4 and the third manifold 5 are provided with partition insertion holes 20 that penetrate the pipe wall. The partition 16 is inserted into the manifold through the partition insertion holes 20 and fixed, dividing the manifold cavity into corresponding transition zones.

[0050] Specifically, the partition 16 is inserted into the manifold through the partition insertion hole 20. The process and assembly are simple, and after insertion, it can be fixed by welding or other methods, ensuring a tight seal. Furthermore, the partition 16 includes a circular plate 21. The side wall of the circular plate 21 has a circumferentially extending and radially protruding snap-fit ​​arc edge 22. The snap-fit ​​arc edge 22 fits precisely into the partition insertion hole 20, and the snap-fit ​​arc edge 22 and its extension length are exactly a semicircle. The side wall of the circular plate 21 away from the snap-fit ​​arc edge 22 is in close contact with the inner wall of the manifold, and the snap-fit ​​arc edge 22 is welded and fixed to the partition insertion hole 20.

[0051] As an optimization, the first manifold 3 is provided with a filling pipe 24 that communicates with the manifold cavity. The filling pipe 24 is located inside the protective cover 25, which is detachably fixed to the first manifold 3. The filling pipe 24 is used for filling the heat exchange medium. Since the heat exchange medium generally does not need to be replaced frequently after filling, the protective cover 25 can effectively protect the filling pipe 24.

[0052] As an optimization, h-shaped fixing seats 26 are respectively provided on the first manifold 3 and the fourth manifold 6; auxiliary fixing pieces 27 are provided on the return connection pipe 12 and the rising connection pipe 17, and the auxiliary fixing pieces 27 are sleeved on the return connection pipe 12 or the rising connection pipe 17 through the connecting through hole; the rising structure 11 and the return structure 9 are distributed at both ends of the arrangement direction of the flat pipe group 7.

[0053] Specifically, the mounting base 26 is used to fix the evaporator plate 2 and the condenser plate 1. It can be provided with holes or grooves for bolts to pass through. The auxiliary fixing piece 27 is sleeved on the connecting pipe to position the connecting pipe and prevent it from being bent. The rising structure 11 and the reflux structure 9 are set on both sides to avoid interference between the reflux transition zone 15 and the rising transition zone 19.

[0054] In this embodiment, the condenser plate 1 and the evaporator plate 2 are parallel, and the connecting pipe 28 is perpendicular to both the condenser plate 1 and the evaporator plate 2.

[0055] Specific working principle: Liquid heat exchange medium fills the first manifold 3 and the flat tube 7 of the evaporator plate 2. The flat tube 7 contacts the hot air for heat exchange. After absorbing heat, the heat exchange medium vaporizes, its density decreases, and it begins to rise against gravity, entering the second manifold 4. Then, it passes through the rising connecting pipe 17, the rising transition zone 19, and the rising channel 18 in sequence into the fourth manifold 6, filling the flat tube 7 of the condenser plate 1. The flat tube 7 of the condenser plate 1 contacts the air for heat exchange. The gaseous heat exchange medium releases heat and liquefies into a liquid state, its density increases, and it flows downward under gravity, entering the third manifold 5. Then, it passes through the return connecting pipe 12, the return transition zone 15, and the return channel 13 in sequence back into the first manifold 3, completing the cycle.

[0056] Example 2

[0057] The working principle of this embodiment is basically the same as that of embodiment 1, except that the angle between the condenser plate 1, the evaporator plate 2 and the connecting pipe 28 is different.

[0058] Specific implementation examples Figure 6 As shown, the condenser plate 1 and the evaporator plate 2 form an acute angle, and the connecting pipe 28 is perpendicular to the condenser plate 1 and forms an acute angle with the evaporator plate 2.

[0059] Example 3

[0060] The working principle of this embodiment is basically the same as that of embodiment 1. The difference is that the connecting pipe 28 and the manifold are connected by a multi-angle connecting structure 29.

[0061] Specific implementation examples Figure 7As shown, the second manifold 4 and the third manifold 5 are connected by a connecting pipe 28. A multi-angle connection structure 29 is provided between the connecting pipe 28 and the second manifold 4 and the third manifold 5. The multi-angle connection structure 29 includes a connecting seat 30. The connecting seat 30 communicates with the interior of the second manifold 4 or the third manifold 5 through the manifold opening 31. The connecting seat 30 is provided with a plurality of circumferentially distributed connecting parts 32. The inner end of the connecting part 32 communicates with the manifold opening 31, and the outer end is closed by a plug 33 or connected to the connecting pipe 28.

[0062] Specifically, the connecting pipe 28 includes a return connecting pipe 12 of the return structure 9 and a rising connecting pipe 17 of the rising structure 11. The connecting pipe 28 is connected to the corresponding manifold through a multi-angle connecting structure 29. The multi-angle connecting structure 29 allows the connection angle between the connecting pipe 28 and the corresponding manifold to be selected as needed, so that the angle between the evaporator plate 2 and the condenser plate 1 has multiple options to adapt to different installation environments. The inner end of the connecting seat 30 is connected to the opening 31 of the manifold, and the outer end is provided with multiple tubular connecting parts 32. The connecting pipe 28 can be inserted into one of the connecting parts 32 for connection, and the remaining free connecting parts 32 are closed by plugs 33. The distribution direction of the multiple connecting parts 32 coincides with the plane of the radial direction of the manifold 4 or 5.
