Description

TECHNICAL FIELD

[0001] The present application relates to a heat exchanger rib plate structure, a heat exchange structure and a heat exchange energy storage device, and is suitable for the technical field of heat exchange. BACKGROUND

[0002] At present, heat exchangers are increasingly becoming important components indispensable to industrial, household and other products, especially with the rapid development of modern technologies such as artificial intelligence and algorithm power, the dependence on heat exchangers is more and more improved. The common technology of heat exchanger is to exchange heat with the heat exchange medium in the environment where the heat exchanger is located through forced convection and natural convection and other heat exchange forms. The determining factors of the heat exchange capacity of the heat exchanger depend on the heat exchange coefficient, heat exchange area and heat exchange temperature difference of the heat exchanger; when the environment where the heat exchanger is located or the structure of the heat exchanger and the unit composed of it is determined, the heat exchange coefficient and the heat exchange temperature difference of the heat exchanger are basically determined, so the heat exchange area of the heat exchanger becomes a key factor to increase the heat exchange capacity.

[0003] At present, the most common way to increase the heat exchange area of the heat exchanger is to increase the fins on the surface of the heat exchanger, and the fins have a good thermal conduction contact relationship with the heat exchanger, so that the heat of the heat exchanger can be conducted to the fins, and the fins can contact the heat exchange medium in the environment to exchange heat. After optimization design, the fins can form an isothermal field with the heat exchanger, thereby effectively increasing the heat exchange area of the heat exchanger.

[0004] As shown in Figure 1 , the common way to increase the heat exchange area of the heat exchanger by adding fins is to wrap fins 20 on the heat exchange pipe 10, and to form a good thermal conduction contact relationship between the heat exchange pipe 10 and the fins 20 through expansion structure, in which case the fins 20 play the role of heat dissipation fins. As shown in Figure 2 , the fins 20 can also be formed by forming an extrusion or other processing technology, and the heat exchange plate 30 contacts the heat exchange element to conduct and exchange heat, which is more suitable for small plane heat exchange. The fins in the above two heat dissipation structures need to be set on the heat exchanger one by one, which is difficult to make and inconvenient to install, and is not suitable for forming on a large plane heat exchanger, and also has problems of complex production process, high energy consumption, etc.

[0005] In the prior art, Chinese patent CN102151741B discloses a plate-fin heat exchanger fin multi-cutter forming die, which also discloses a heat exchanger fin formed by die bending, but there is an inner cavity between the two side walls of the heat exchanger fin, which forms a heat air gathering space, limits the heat dissipation to the outside, and the length of the contact surface between the heat exchanger fin and the heat exchanger is only one thickness, the heat contact area is limited, which will seriously affect the heat conduction and further affect the heat dissipation efficiency.

[0006] Therefore, the prior art needs a heat exchanger rib plate structure, a heat exchange structure and a heat exchange energy storage device to solve the heat dissipation problem of the existing heat exchanger. Utility model content

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other. Those skilled in the art will understand that the heat exchanger fin structure, heat exchange structure, and heat exchange energy storage device of this application are suitable for heat dissipation and energy storage of existing heat sources. The energy storage in this application may refer to thermal energy or cold energy.

[0039] like Figures 3-6 As shown, this application discloses a heat exchanger rib structure, which includes a metal plate 1 and ribs 2 integrally formed on the surface of the metal plate 1. The ribs 2 protrude outward from the metal plate 1 to form a heat dissipation structure. The metal plate 1 in this application can be a metal film, the thickness of which can be selected to be less than 0.1 mm; or, preferably, the metal plate is an aluminum plate or a copper plate. Figure 6As shown, the rib plate 2 of the present application includes a first side wall 21 and a second side wall 22, and the first side wall 21 and the second side wall 22 are attached to each other, so that the hollow size between the first side wall 21 and the second side wall 22 can be shortened to the maximum, the direct contact area between the metal plate 1 and the heat source is increased, and the heat dissipation efficiency is effectively improved. The heat exchanger rib plate structure provided by the present application is formed by directly extruding the metal plate 1, the rib plate 2 and the metal plate 1 are integrated, and the rib plate can be formed by extruding the metal plate itself, which is very convenient to manufacture, and the installation is also convenient. The rib plate 2 does not need to be welded or fixed to the heat exchanger one by one or by other means, but only needs to be directly attached to the heat exchange surface of the heat exchanger, so the installation is more convenient and the heat dissipation efficiency is higher.

[0040] As shown in Figures 3-6 In some embodiments, a plurality of rib plates 2 are provided on the metal plate 1, and the plurality of rib plates 2 can be provided on one side of the metal plate 1 or on both sides of the metal plate 1 respectively to form a heat dissipation structure and achieve efficient heat dissipation. Figures 3 to 4 As shown in Figure 5 Preferably, a plurality of rib plates 2 can be provided on both sides of the metal plate 1 at the same interval or symmetrically intersected on both sides of the metal plate 1, so that the heat exchange area between the rib plate and the environment medium is increased, and the contact area between the rib plate and the heat exchanger is also increased, thereby achieving efficient heat dissipation.

[0041] As shown in Figure 7 In some embodiments, in order to improve the heat exchange efficiency of the rib plate 2, a rib 23 is formed on the side wall of the rib plate 2 by extrusion, which can further expand the heat dissipation area and improve the heat dissipation efficiency. Preferably, the rib 23 is pre-formed on the side wall of the rib plate 2 by extrusion, that is, the metal plate 1 is extruded to form the rib 23 before the rib plate 2 is extruded, and then the metal plate 1 is extruded to form the rib plate 2 according to the predetermined size, so that the rib 23 is just on the side wall of the rib plate 2. The positions of the ribs 23 on the side wall of the rib plate 2 can be staggered to improve the heat dissipation space; the positions of the ribs 23 on the side wall of the rib plate 2 can also be the same, which is convenient for extrusion.

[0042] As shown in Figure 12As shown, in some embodiments, the rib plate structure designed by the present application also includes heat exchange pipes 10. The metal plate 1 is provided with a plurality of rib plates 2, and the rib plate 2 is formed with a flange hole 24. The heat exchange pipe 10 is respectively sleeved in the flange hole 24 of the rib plate 2, and is in close contact with the inner wall of the flange hole 24 to realize contact heat dissipation and improve the heat dissipation efficiency. In the above scheme, the first side flange hole 241 is formed on the first side wall 21 of the rib plate 2, and the second side flange hole 242 is formed on the second side wall 22 of the rib plate 2. The first side flange hole 241 and the second side flange hole 242 can be mirror image arranged. By directly sleeving the heat exchange pipe 10 in the flange hole 24 of each rib plate 2, a heat dissipation structure is formed, in which the heat exchange efficiency can be improved by the heat exchange medium in the heat exchange pipe 10.

[0043] As shown, Figure 8 The rib plate structure of the heat exchanger designed by the present application is shown. The most important key size of the rib plate 2 is the thickness δ of the base material, the rib plate height h and the width b between adjacent rib plates. The thinner the thickness δ, the smaller the conduction thermal resistance, and the heat can be more easily conducted to the rib plate 2. The rib plate height h determines the heat exchange area s formed per unit rib plate length. The larger the rib plate height h, the larger the heat exchange area s, and the better the heat exchange effect. However, it is not necessarily the larger the rib plate height h, but also needs to consider the uniformity of the temperature field of the rib plate. The spacing b between the two adjacent rib plates also determines the heat exchange area per unit rib plate length, but also needs to consider the physical properties of the heat exchange medium and the cleanliness of the heat exchange medium. Preferably, the spacing b between the two adjacent rib plates of the present application satisfies: 10δ≤b, so that a better heat exchange area can be obtained. Preferably, the thickness of the rib plate 2 = 2δ (i.e. the first side wall 21 and the second side wall 22 are in close contact with each other), which can maximize the contact area formed by the rib plate to form the largest conduction contact surface with the heat source.

[0044] As shown, Figures 9-11 In some embodiments, the two ends of the metal plate 1 are in close contact to form a heat exchange cavity 3, and the rib plate 2 is arranged outside the heat exchange cavity 3. Figure 9 As shown, the metal plate 1 can be rolled or folded into a polygonal structure, and the two ends are sealed, so that the metal plate 1 surrounds a heat exchange cavity 3. The heat exchange cavity 3 can be circulated with a heat exchange medium, so as to realize heat exchange between the heat exchange medium and the environment medium in which the heat exchange cavity 3 is located. Specifically, one end of the metal plate 1 is a first interface 11, and the other end is a second interface 12. By butting the first interface 11 and the second interface 12, the heat exchange cavity 3 can be formed. The rib plate structure of the present application is convenient to directly extrude and form, and is easy to process.

[0045] As shown, Figures 9-10 In some embodiments, the metal plate 1 can be rolled in the F direction to form a circular heat exchange channel, i.e. to make the cross section of the heat exchange cavity 3 circular. Figure 11As shown, in some embodiments, the metal plate 1 can be folded along the F direction to form a polygonal heat exchange channel, i.e. to make the cross section of the heat exchange cavity 3 a quadrilateral. The different heat exchange channels described above can be applied to different heat exchangers, improving applicability.

[0046] Reference Figure 12 As shown, the present application also provides a heat exchange structure, comprising a rib plate structure and a heat source 31; wherein the rib plate structure is the heat exchanger rib plate structure described above. The rib plate structure and the heat source 31 are attached to each other to achieve heat conduction. Specifically, the rib plate 2 of the rib plate structure can be tightly bonded with the heat source 31 to form a good heat conduction relationship. The heat source 31 can be a pipeline with a heat exchange medium circulating or a heat source generating heat through physical and chemical reactions. Through the good heat conduction relationship between the rib plate 2 and such heat source, the heat on the heat source 31 can be directly and efficiently conducted to the rib plate 2. Heat exchange occurs between the rib plate 2 and the environment medium, which can be air, water or oil, etc.

[0047] As Figures 9-11 As shown, in some embodiments, the metal plate 1 forms a heat exchange cavity 3. Specifically, the two ends of the metal plate 1 are bonded with each other to form the heat exchange cavity 3. The heat source 31 can be a heat exchange pipe 10, which can be arranged in the heat exchange cavity 3 and attached to the inner wall of the metal plate 1 to achieve heat transfer.

[0048] As Figure 13 As shown, the present application also provides a heat exchange energy storage device, comprising a heat exchange structure and an energy storage component 5, wherein the heat exchange structure is the heat exchange structure described above. Specifically, the heat exchange structure and the energy storage component 5 are attached to each other to achieve heat transfer and heat storage. The use of the heat exchange structure described above enables the heat exchange energy storage device to achieve energy storage while further achieving heat dissipation. The energy storage component can achieve simultaneous energy storage under various working conditions. For example, when using a phase change material for energy storage, the energy storage component can be a phase change material with a certain phase change temperature, or two or more phase change materials with different phase change temperatures. Considering that the energy storage energy required by two or more phase change temperatures is different, the ratio of the amount of energy storage material required can be matched, and the energy storage materials are arranged at intervals in the heat exchange structure.

[0049] As Figure 13 As shown, in some embodiments, the heat exchange energy storage device provided by the present application further comprises a shell 4, and the energy storage component 5 is arranged in the shell 4 to achieve energy absorption and storage. The shell 4 is provided with a through hole, and the rib plate 2 of the heat exchange structure is inserted into or passes through the through hole to achieve heat dissipation. Specifically, the heat exchange structure is at least partially arranged in the shell 4 and attached to the energy storage component 5 to achieve heat transfer and store energy through the energy storage component 5. The rib plate 2 of the heat exchange structure passes through the through hole on the wall surface of the shell 4 and extends to the outside of the shell 4 to achieve heat dissipation.

[0050] The heat exchanger rib plate structure, heat exchange structure and heat exchange energy storage device have the following technical advantages:

[0051] (1) The heat exchanger rib plate structure is directly formed by processing a metal plate, which is convenient to manufacture and install, and does not need to be welded or fixed to the heat exchanger by other means.

[0052] (2) The two side walls of the rib plate structure of the heat exchanger rib plate structure are in close contact with each other, which increases the direct contact area between the rib plate structure and the heat source, and effectively improves the heat dissipation efficiency.

[0053] (3) The length of the contact surface of the heat exchanger rib plate structure is twice that of a single fin, which effectively increases the heat exchange area and realizes efficient heat dissipation.
