Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a heat exchange device and an electrical equipment. Background Art

[0002] The heat exchange device is a commonly used component in electrical equipment, used to discharge the heat generated by the components inside the electrical equipment during operation. For electrical equipment with relatively high operating requirements, generally, the cavity where the internal components are located needs to be designed with a high protection level, such as to achieve the purpose of dust prevention and waterproofing. For the cavity structure of electrical equipment with a high protection level, it cannot directly exchange air with the outside world. And with the increase of power density, the requirement for the heat exchange efficiency of the heat exchanger is getting higher and higher, and at the same time, it needs to meet the adaptation and installation of the cavity of the electrical equipment.

Detailed implementation mode

[0036] The core of the present utility model lies in disclosing a heat exchange device with stronger structural installation adaptability to electrical equipment and better heat exchange efficiency.

[0037] Another core of the present utility model lies in disclosing an electrical equipment using the above heat exchange device.

[0038] To enable those skilled in the art to better understand the solution of the present utility model, the embodiments of the present utility model will be described below with reference to the accompanying drawings. In addition, the embodiments shown below do not impose any limitation on the content of the utility model recorded in the claims. Moreover, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model recorded in the claims.

[0039] As Figure 1 and Figure 2 shown, the heat exchange device provided by the embodiment of the present utility model includes a support member 10 and a heat dissipation device 20. Among them, the support member 10 includes a carrier plate 110. At the same time, a first mounting surface 120 is extended at the first end of the carrier plate 110. It should be noted that the first mounting surface 120 and the support plate are also plate structures, and the first mounting surface 120 is bent and connected to the carrier plate 110 to form a load-bearing basic structure with a bent structure.

[0040] At the same time, the heat dissipation device 20 penetrates through the carrier plate 110 and is separated by the carrier plate 110 into a first heat exchange module 210 and a second heat exchange module 220. At the same time, the first heat exchange module 210 and the second heat exchange module 220 are internally connected to be able to be filled with a phase change medium to achieve the purpose of heat transfer.

[0041] It should be noted that the carrier plate 110 is used for separating and arranging the first heat exchange module 210 and the second heat exchange module 220. On the basis of the above structure, a first mounting surface 120 is further extended at the first end of the carrier plate 110. The first mounting surface 120 and the carrier plate 110 are also plate structures and are bent and connected. On the one hand, the first mounting surface 120 can, through the bent structure, enclose the heat exchange module on one side of the carrier plate 110, and further isolate the two heat exchange modules to ensure their independent heat exchange functions; on the other hand, the carrier plate 110 and the first mounting surface 120 with the bent structure can, on the basis of providing good support for the first heat exchange module 210 and the second heat exchange module 220, realize good connection in the opening area of the target device by setting mounting structures such as buckles and bolt holes on the extended structure, or welding connection areas.

[0042] In order to further improve the peripheral enclosure structure of the first heat exchange module 210 and the second heat exchange module 220, so that the two heat exchange modules can exchange heat more independently, as Figure 1 and Figure 3As shown, the support member 10 provided in the embodiment of the present application further includes a second mounting surface 130. Similar to the first mounting surface 120, the second mounting surface 130 is provided at the second end of the carrier plate 110 in a bent structure, and preferably, the second mounting surface 130 is parallel to the first mounting surface 120. In this structure, the carrier plate 110 first divides the heat dissipation device 20, and the first mounting surface 120 and the second mounting surface 130 are located at opposite ends of the carrier plate 110, extending in opposite directions in the Z direction, that is, Figure 1 extending in the positive and negative directions of the Z direction in [reference numeral], so as to expand the dividing effect of the carrier plate 110, and isolating the first heat exchange module 210 and the second heat exchange module 220 in a larger cross-sectional area on the XZ plane in Figure 1 [reference numeral]; the extension of the isolation structure of the first heat exchange module 210 and the second heat exchange module 220 can provide greater freedom for the installation of the heat exchange device and improve the structural adaptability of the heat exchange device on the premise of meeting the condition that the first heat exchange module 210 and the second heat exchange module 220 are respectively arranged inside and outside the target equipment housing.

[0043] On this basis, as Figure 1 shown, some embodiments of the present application further provide side plates 140. One side plate 140 is provided at each of the two sides of the support member 10 in the Y direction in Figure 1 [reference numeral], and each side plate 140 is perpendicular to both the first mounting surface 120 and the second mounting surface 130. Preferably, the height of the side plate 140 in the Z direction in Figure 1 [reference numeral] covers the first mounting surface 120 and the second mounting surface 130. The setting of the side plates 140 in combination with the carrier plate 110, the first mounting surface 120, and the second mounting surface 130 can completely separate the first heat exchange module 210 and the second heat exchange module 220 in two cavity structures, not only meeting their respective heat exchange requirements, but also forming an independent and relatively closed air duct structure, and a wind power device can be set to blow the air flow to achieve the effect of accelerating heat exchange.

[0044] Based on the above embodiments, after the side plates 140 are cooperatively arranged with the carrier plate 110, the first mounting surface 120, and the second mounting surface 130, the cavity structures where the first heat exchange module 210 and the second heat exchange module 220 are located are open structures in the positive and negative directions of the Z-axis respectively. Combining with the openings in the X-axis will result in poor sealing of the first heat exchange module 210 and the second heat exchange module 220 in their respective cavity structures, making it difficult to concentrate the air flow by the wind power device. Therefore, in some embodiments of the present application, in order to improve the enclosure effect of the first heat exchange module 210 and the second heat exchange module 220 and optimize the air flow diversion effect of the wind power device and the like, the heat dissipation device 20 further includes a first partition plate 150 and a second partition plate 160. The first partition plate 150 and the second partition plate 160 are arranged at both ends of the heat dissipation device 20 in the direction perpendicular to the carrier plate 110, that is, the Z-axis. At the same time, the first partition plate 150 and the second partition plate 160 are parallel to the carrier plate 110, so that the heat dissipation device 20 maintains a good external structure. Similarly, in the X-axis direction, the first partition plate 150 is fixedly connected to the side surface or the end edge of the first mounting surface 120, while the second partition plate 160 is fixedly connected to the side surface or the end edge of the second mounting surface 130; in the Y-axis direction, both sides of the first partition plate 150 and the second partition plate 160 are butted and fixed to the side plates 140 on both sides to form a stable connection structure.

[0045] It should be noted that the arrangement of the first partition plate 150 and the second partition plate 160 enables the first heat exchange module 210 and the second heat exchange module 220 to have only one opening structure in the opposite directions in the X-axis. It can not only form a stable air flow channel, enabling the wind power device to be more conveniently arranged to blow and guide the air flow, thereby accelerating the heat exchange efficiency of the first heat exchange module 210 and the second heat exchange module 220; at the same time, when the cavity structure with a single opening is connected to the housing of the target device, it has a higher degree of freedom, that is, the side wall structures of the cavity can all be used as connection structures. It only needs to ensure that in the cavities where the first heat exchange module 210 and the second heat exchange module 220 are located, the opening of one cavity is communicated with the internal area of the housing, and the opening of the other cavity is communicated with the external connection interface of the housing, improving the structural adaptability of the heat exchange device.

[0046] For the heat dissipation device 20 provided in the embodiments of the present application, as Figure 2As shown, it specifically includes a substrate 230 with an integral structure, a first fin 240, and a second fin 250. The substrate 230 is a flat structure for carrying the first fin 240 and the second fin 250. The first fin 240 and the second fin 250 can be assembled and connected to the substrate 230 or integrally formed. In particular, after the heat dissipation device 20 is separated by the carrier plate 110, the first heat exchange module 210 is composed of a plurality of first fins 240 arranged in parallel, and the second heat exchange module 220 is composed of a plurality of second fins 250 arranged in parallel. The first fin 240 and the second fin 250 have a connected flow channel to enable the phase change medium to smoothly displace within the first fin 240 and the second fin 250 for heat transfer. The advantage of separating the first fin 240 and the second fin 250 into the first cavity and the second cavity respectively is that they can be maintained and adjusted separately. At the same time, the fins within a single cavity remain parallel, which can adjust the outflow angle of the wind power device when setting up the wind power device, so that the wind power device adapts to the fin angle in the corresponding cavity.

[0047] Furthermore, in the heat exchange device provided in the embodiment of the present application, the heat exchange functions of the first fin 240 and the second fin 250 are carried out in two relatively independent cavities respectively. Therefore, the first fin 240 and the second fin 250 only need to maintain a connected state to meet the movement of the phase change medium, and their structures can be set arbitrarily. For example, in an embodiment of the present application, as Figure 2 and Figure 8 shown, the first fin 240 and the second fin 250 are symmetrically arranged on the substrate 230 to maintain a regular appearance and facilitate installation. The first fin 240 and the second fin 250 can be replaced with each other, and there is no need to consider the front and back during installation. In another embodiment of the application, as Figure 7 shown, the normal lines of the first fin 240 and the second fin 250 are perpendicularly arranged. Specifically, while both the first fin 240 and the second fin 250 are perpendicular to the substrate 230, the first fin 240 and the second fin 250 are also perpendicular to each other, that is, one of the first fin 240 and the second fin 250 extends along the Z direction, and the other extends along the Y direction; in this embodiment, the first fin 240 and the second fin 250 have different shapes, and they can adapt to wind power devices with different orientations during installation. When the internal space of the target device is limited, resulting in the wind power device can only be installed in a specific posture, the heat exchange device in this embodiment can meet its use.

[0048] Furthermore, in the heat exchange device provided in the embodiments of the present application, a connected flow channel is required between the first fins 240 and the second fins 250 to satisfy the transfer of the phase change medium between the two heat exchange modules. Therefore, in some embodiments of the present application, the first fins 240 and the second fins 250 are arranged in one-to-one correspondence and connection. At the same time, the integrated first fins 240 and second fins 250 penetrate through the substrate 230. That is, in this embodiment, the substrate 230 only serves as a supporting structure and is not arranged as a flow channel for the phase change medium. And the one-to-one correspondence and connection here specifically means that a single first fin 240 and a single second fin 250 are connected and combined into an integrated structure, which penetrates through the substrate 230. The substrate 230 is arranged as a plate structure for carrying and supporting the first fins 240 and the second fins 250. The phase change medium between a single first fin 240 and the second fin 250 will not move to other positions, and the filling amounts of the phase change medium in each of the first fins 240 and the second fins 250 are uniform, and the corresponding heat dissipation effect is also more uniform.

[0049] In other embodiments, the substrate 230 is a hollow accommodating structure, and both the first fins 240 and the second fins 250 are connected to the hollow cavity of the substrate 230. That is, the first fins 240 and the second fins 250 use the hollow cavity of the substrate 230 as a transfer flow channel for the phase change medium to complete the heat exchange and movement of the phase change medium. In this embodiment, the heat dissipation device 20 can fill more phase change medium and thus has a larger single heat exchange threshold.

[0050] In addition, regarding the setting relationship between the substrate 230 and the carrier plate 110, in some embodiments of the present application, as Figure 1 and Figure 3 shown, the substrate 230 and the carrier plate 110 are arranged in parallel. An embedding space for the substrate 230 is reserved on the carrier plate 110 so that the substrate 230 can be completely and hermetically embedded in the carrier plate 110 and connected to the carrier plate 110 as an integrated structure, or the carrier plate 110 and the substrate 230 are the same plate structure and have the composite functions of partitioning and carrying. Correspondingly, all the first fins 240 on one side of the substrate 230 are in the first heat exchange module 210 separated by the carrier plate 110, and all the second fins 250 on one side of the substrate 230 are in the second heat exchange module 220 separated by the carrier plate 110. The above structure can maintain the sealed state of the carrier plate 110 after the substrate 230 is installed, and avoid air leakage due to the communication of the cavities where the first heat exchange module 210 and the second heat exchange module 220 are located.

[0051] In other embodiments of the present application, as Figure 4As shown, the substrate 230 is disposed perpendicular to the carrier plate 110 and passes through the carrier plate 110. Correspondingly, the first fins 240 and the second fins 250 are respectively disposed on both sides of the carrier plate 110, and one side of the substrate 230 has both a part of the first fins 240 and a part of the second fins 250. The first fins 240 and the second fins 250 are hierarchically distinguished in the vertical direction of the substrate 230, that is, the Z direction. In this structure, only a through groove structure for the substrate 230 to pass through needs to be opened on the carrier plate 110 to complete the installation of the substrate 230 passing through. The structural processing requirements for the carrier plate 110 are small, and there is no need to open a large groove, thereby reducing the risk of communication leakage between the first heat exchange module 210 and the second heat exchange module 220 on both sides of the carrier plate 110, and improving the operating stability of the heat exchange device.

[0052] Further, on the basis of the above embodiments, the relative positions of the first fins 240 and the second fins 250 with respect to the substrate 230 can be set arbitrarily, and only need to ensure that several first fins 240 are arranged in parallel and several second fins 250 are arranged in parallel to make the effective action after the wind power device is set. Therefore, in some specific embodiments of the application, as Figure 5 shown, the proximal end of the first fin 240 is connected to the substrate 230 to maintain a stable structure, and the distal end of the first fin 240 is inclined toward the direction of the first partition 150, so that several first fins 240 are arranged in an upwardly inclined airfoil structure.

[0053] It should be noted that, in some embodiments of the present application, for the structure in which the substrate 230 is disposed perpendicular to and passes through the carrier plate 110, as Figure 6 shown, the first fins 240 and the second fins 250 can also be disposed on one side of the substrate 230, or can be disposed on both sides. According to the heat exchange working condition requirements, the corresponding setting method is selected. When the heat exchange requirement is not high, a structure in which only one side of the substrate 230 has the first fins 240 and the second fins 250 can be selected to reduce the overall operating cost of the structure while meeting the use requirements.

[0054] When the cross-sectional length of the first fin 240 is limited by the structure, the inclined first fin 240 has a larger storage volume and surface area, and can store and use more phase change media, thereby improving the heat exchange efficiency. At the same time, the inclined structure can have a larger interval between adjacent first fins 240, so that the air flow can contact and exchange heat with the first fins 240 more fully.

[0055] Correspondingly, the second fin 250 can be disposed perpendicular to the substrate 230 or can be inclined. When the second fin 250 is inclined with respect to the substrate 230, the proximal end of the second fin 250 is connected to the substrate 230, and the distal end is inclined toward the direction of the second partition 160 to form an airfoil structure opposite to that of the first fin 240.

[0056] It should be noted that, as Figure 9 shown, when the first fin 240 and the second fin 250 are disposed on opposite sides of the substrate 230, they can also be staggeredly arranged to meet the requirements of position installation and use.

[0057] To further optimize the above technical solution, as Figure 7 well as Figure 8 shown, in some embodiments of the present application, corrugated teeth 260 are provided between adjacent first fins 240. The corrugated teeth 260 are preferably made of materials with good heat conduction effects, such as aluminum, copper, etc., for accelerating heat exchange with the surrounding air. When the fin structure dissipates heat, part of the heat on the fins is carried away by the air flow provided by the wind power device, while the other part is transferred to the corrugated teeth 260. The corrugated teeth 260 have a large specific surface area and can quickly exchange heat under the blowing of the air flow to reduce the temperature of the fins, achieving the purpose of high-speed heat exchange.

[0058] Similarly, corrugated teeth 260 can also be provided between adjacent second fins 250 to achieve the purpose of accelerating heat exchange by increasing the specific surface area.

[0059] In addition, as Figure 10 shown, in some embodiments of the present application, an electrical device is further provided. The electrical device includes a box body and electrical components 320 that operate safely and are disposed inside the box body. The electrical components 320 are heat-generating components, and on the casing 310 that forms the enclosure structure of the box body, the heat exchange device provided in any of the above embodiments is provided for heat exchange. Specifically, an installation opening 330 communicating the inner and outer regions of the casing 310 is formed on one side of the casing 310. The electrical components 320 are disposed inside the enclosed area of the casing 310 to be protected by the casing 310. The heat exchange device is fixedly connected to the position of the installation opening 330 through the support member 10 and seals the installation opening 330 to keep the casing 310 in a good sealed state. It should be noted that the installation of the heat exchange device is specifically that the heat exchange device is fixedly connected to the side wall of the casing through its carrier plate 110 and the extending structures on the carrier plate 110, such as the first installation surface 120, the second installation surface 130, etc., so that one of the first heat exchange module 210 and the second heat exchange module 220 located on both sides of the carrier plate 110 is located inside the enclosure area of the casing 310, while the other is located outside the enclosure area of the casing 310.

[0060] Specifically, when the heat exchange device is installed on the electrical device, there are at least three installation states, such as Figure 11As shown in the figure, a heat exchange device is entirely recessed within the enclosure structure of the chassis 310 when installed at the installation opening 330. It is applicable to electrical equipment with sufficient layout space for internal electrical components 320. At this time, the overall appearance of the electrical equipment is the outer shape structure enclosed by the chassis 310, without any protruding areas, making it easy to transport and arrange as a whole. At this time, the first heat exchange module 210 is in communication with the area where the electrical components 320 are arranged to absorb the heat generated during the operation of the electrical components 320, while the second heat exchange module 220 is in communication with the external area of the chassis 310 for heat dissipation with the outside air.

[0061] It should be noted that in the above embodiment, the first heat exchange module 210 is an evaporation module. The first heat exchange module 210 absorbs the heat generated during the operation of the electrical components 320, and the liquid phase change medium inside it vaporizes. At the same time, the second heat exchange module 220 is a condensation module, which is in contact with the external environment to release heat and liquefy the gaseous phase change medium inside. Also, in the vertical direction, the installation height of the second heat exchange module 220 is higher than that of the first heat exchange module 210, that is, the installation height of the condensation module is higher than that of the evaporation module. After vaporizing in the evaporation module, the phase change medium can rise to the condensation module by itself, and after liquefying in the condensation module, it can flow smoothly to the evaporation module under the action of gravity to complete the cycle smoothly.

[0062] As Figure 12 shown in the figure, another installation form of the heat exchange device is that when the heat exchange device is installed at the installation opening 330, it is entirely protruded outside the enclosure structure of the chassis 310. This structure is applicable to electrical equipment with a relatively compact layout space for internal electrical components 320. The installation of the heat exchange device will not affect the internal space of the chassis 310. At this time, the second heat exchange module 220 is in communication with the area where the electrical components 320 are arranged, while the first heat exchange module 210 is in communication with the outside air to enable the heat exchange device to dissipate heat inside the electrical equipment smoothly.
