DETAILED DESCRIPTION

[0040] The core of the present application is to disclose a heat exchange device.

[0041] Another core of the present application is to disclose an electrical device using the heat exchange device.

[0042] In order to make the person skilled in the art better understand the present application, the following embodiments of the present application are described with reference to the accompanying drawings, and in addition, the following embodiments shown do not limit the application content recorded in the claims in any way. In addition, the entire content of the following embodiments is not limited to the solution necessary for the application recorded in the claims.

[0043] In some embodiments, as shown in FIG. 1 and FIG. 2, the heat exchange device comprises a support 10 and a heat dissipation device 20, wherein the support 10 comprises a bearing plate 110, and the first end of the bearing plate 110 is provided with a first mounting surface 120, it should be noted that the first mounting surface 120 is also a plate structure, and the first mounting surface 120 is bent connected with the bearing plate 110 to form a bearing base structure with a bending structure.

[0044] At the same time, the heat dissipation device 20 is provided through the bearing plate 110 to be separated into a first heat exchange module 210 and a second heat exchange module 220 by the bearing plate 110, and the first heat exchange module 210 and the second heat exchange module 220 are internally communicated to be able to fill the phase change medium for the purpose of heat transfer.

[0045] It should be noted that the bearing plate 110 is used for the separation of the first heat exchange module 210 and the second heat exchange module 220, and on the basis of the above structure, the first end of the bearing plate 110 is further provided with the first mounting surface 120, and the first mounting surface 120 is also a plate structure and is bent connected with the bearing plate 110. On the one hand, the first mounting surface 120 can pass through the bending structure to enclose the heat exchange module on one side of the bearing plate 110, and further isolate the two heat exchange modules to ensure their independent heat exchange effect; on the other hand, the bearing plate 110 and the first mounting surface 120 with the bending structure can be well supported on the basis of the first heat exchange module 210 and the second heat exchange module 220, and by providing mounting structures such as buckles, bolt holes or welding connection areas on the extension structure, the good connection of the opening area of the target device can be realized.

[0046] In order to further improve the peripheral enclosure of the first heat exchange module 210 and the second heat exchange module 220, so that the two heat exchange modules can more independently exchange heat, as shown in FIG. 1 and FIG. 3, the support 10 provided by the embodiments of the present application further comprises a second mounting surface 130. The second mounting surface 130 is also arranged in a bent structure at the second end of the bearing plate 110, and preferably the second mounting surface 130 is arranged in parallel with the first mounting surface 120. In this structure, the bearing plate 110 first separates the heat dissipation device 20, and the first mounting surface 120 and the second mounting surface 130 are arranged at opposite ends of the bearing plate 110, and the end of the bearing plate 110 extends in the opposite direction, i.e. the positive and negative directions of the Z direction in FIG. 1, to expand the separation effect of the bearing plate 110, and to isolate the first heat exchange module 210 and the second heat exchange module 220 in a larger cross-sectional area in the XZ plane in FIG. 1; 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 under the premise of meeting the requirement that the first heat exchange module 210 and the second heat exchange module 220 are separately arranged inside and outside the target equipment shell, and improve the structural adaptability of the heat exchange device.

[0047] On this basis, as shown in FIG. 1, some embodiments of the present application further provide side plates 140, one side plate 140 is arranged at each of the two side positions of the support 10 in the Y direction in FIG. 1, and each side plate 140 is arranged perpendicular to the first mounting surface 120 and the second mounting surface 130, and preferably the side plate 140 is arranged in the Z direction in FIG. 1. The height of the first mounting surface 120 and the second mounting surface 130 is covered, and the arrangement of the side plate 140 in combination with the bearing 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 and arrange them in two cavity structures, not only meeting their respective heat exchange requirements, but also forming independent and relatively closed air duct structures, which can be blown by the wind power equipment to accelerate the heat exchange effect.

[0048] On the basis of the above-mentioned embodiments, after the side plate 140 is arranged in cooperation with the bearing plate 110, the first mounting surface 120 and the second mounting surface 130, the cavity structure in which the first heat exchange module 210 and the second heat exchange module 220 are respectively arranged is open in the positive direction and the reverse direction of the Z direction. In combination with the opening in the X direction, the first heat exchange module 210 and the second heat exchange module 220 are poor in sealing in the respective cavity structures, and it is difficult to concentrate airflow by arranging the wind power equipment. 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 airflow guiding effect of the wind power equipment on the airflow, the heat dissipation device 20 further comprises 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 the two ends of the heat dissipation device 20 in the direction perpendicular to the bearing plate 110, i.e. the Z direction, and the first partition plate 150 and the second partition plate 160 are arranged in parallel with the bearing plate 110, so that the heat dissipation device 20 maintains a good external shape. Similarly, in the X direction, the first partition plate 150 is fixedly connected with the side or end edge of the first mounting surface 120, and the second partition plate 160 is fixedly connected with the side or end edge of the second mounting surface 130. In the Y direction, the two sides of the first partition plate 150 and the second partition plate 160 are in abutment with and fixed to the two side plates 140, thereby forming a stable connection structure.

[0049] 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 an opening structure only in the opposite direction of the X direction. This not only forms a stable airflow channel, so that the wind power equipment can be more conveniently arranged to blow and guide the airflow and accelerate the heat exchange efficiency of the first heat exchange module 210 and the second heat exchange module 220, but also has higher freedom when the single-opening cavity structure is connected with the shell of the target equipment, i.e. the side wall structure of the cavity can be used as a connection structure. It is only necessary to ensure that the opening of one cavity in the cavity in which the first heat exchange module 210 and the second heat exchange module 220 are arranged is connected with the internal region of the shell, and the opening of the other cavity is connected with the external interface of the shell, thereby improving the structural adaptability of the heat exchange device.

[0050] For the heat dissipation device 20 provided in the embodiment of the present application, as shown in FIG. 2, it specifically comprises a base plate 230, a first fin 240 and a second fin 250 in an integrated structure, the base plate 230 is in a flat plate structure for bearing the first fin 240 and the second fin 250, the first fin 240 and the second fin 250 can be assembled with the base plate 230 or integrally formed, and in particular, after the heat dissipation device 20 is separated by the bearing plate 110, the first heat exchange module 210 is composed of a plurality of parallel arranged first fins 240, and the second heat exchange module 220 is composed of a plurality of parallel arranged second fins 250, the first fin 240 and the second fin 250 have a communicating flow channel so that the phase change medium can smoothly move in the first fin 240 and the second fin 250 to transfer heat. The advantage of arranging the first fin 240 and the second fin 250 in the first cavity and the second cavity respectively is that they can be maintained and adjusted separately, and the fins in a single cavity remain in a parallel state, so that when the air blowing device is arranged, the outflow angle of the air blowing device can be adjusted to adapt to the fin angle in the corresponding cavity.

[0051] Further, in the heat exchange device provided in the embodiment of the present application, the heat exchange of the first fin 240 and the second fin 250 is performed in two relatively independent cavities respectively, so that the first fin 240 and the second fin 250 only need to maintain a communicating state to meet the movement of the phase change medium, and their structure can be arranged arbitrarily. In one embodiment of the present application, as shown in FIG. 2 and FIG. 8, the first fin 240 and the second fin 250 are symmetrically arranged on the base plate 230 to maintain a regular appearance for easy installation, and the first fin 240 and the second fin 250 can be replaced with each other without considering the front and back during installation. In another embodiment of the present application, as shown in FIG. 7, the normal lines of the first fin 240 and the second fin 250 are arranged perpendicular to each other, specifically, the first fin 240 and the second fin 250 are both arranged perpendicular to the base plate 230, and the first fin 240 and the second fin 250 are also arranged perpendicular to each other, that is, one of the first fin 240 and the second fin 250 is arranged along the Z direction, and the other is arranged along the Y direction; in this embodiment, the first fin 240 and the second fin 250 have different forms, which can adapt to air blowing devices with different orientations during installation, and when the internal space of the target device is limited so that the air blowing device can only be installed in a specific posture, the heat exchange device in this embodiment can meet the use thereof.

[0052] Further, in the heat exchange device provided by the embodiments of the present application, the first fins 240 and the second fins 250 need to have a communicating flow channel to meet 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 correspondingly and communicatively arranged, and the integrated first fins 240 and second fins 250 are arranged through the substrate 230, that is, in this embodiment, the substrate 230 only serves as a bearing structure, and is not arranged as a flow channel of the phase change medium, and the corresponding and communicatively arranged specifically means that a single first fin 240 and a single second fin 250 are communicated and combined into an integrated structure, which is arranged through the substrate 230, the substrate 230 is arranged as a plate structure for bearing and supporting the first fins 240 and the second fins 250, the phase change medium between the single first fin 240 and the single second fin 250 cannot move to other positions, and the filling amount of the phase change medium in each first fin 240 and second fin 250 is uniform, and the corresponding heat dissipation effect is also more uniform.

[0053] In other embodiments, the substrate 230 is a hollow accommodating structure, and the first fins 240 and the second fins 250 are both arranged in communication with the hollow cavity of the substrate 230, that is, the first fins 240 and the second fins 250 pass through the hollow cavity of the substrate 230 as a transfer flow channel of 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 has a larger single heat exchange threshold.

[0054] In addition, for the arrangement relationship between the substrate 230 and the bearing plate 110, in some embodiments of the present application, as shown in FIG. 1 and FIG. 3, the substrate 230 and the bearing plate 110 are arranged in parallel, and the bearing plate 110 has a reserved embedding space for the substrate 230, so that the substrate 230 can be completely sealed and embedded in the bearing plate 110, and connected into an integrated structure with the bearing plate 110, or the bearing plate 110 and the substrate 230 are the same plate structure, and have the functions of separation and bearing. Correspondingly, all the first fins 240 on one side of the substrate 230 in the first heat exchange module 210 separated by the bearing plate 110, and all the second fins 250 on one side of the substrate 230 in the second heat exchange module 220 separated by the bearing plate 110. The above structure can maintain the sealing state of the bearing plate 110 after the substrate 230 is installed, to avoid the communication of the cavities where the first heat exchange module 210 and the second heat exchange module 220 are located.

[0055] In some embodiments of the present application, as shown in FIG. 4, the substrate 230 is arranged perpendicularly to the carrier plate 110 and passes through the carrier plate 110, and the first fins 240 and the second fins 250 are arranged on the two sides of the carrier plate 110, respectively, and the substrate 230 has part of the first fins 240 and part of the second fins 250 on one side, and the first fins 240 and the second fins 250 are layered in the vertical direction of the substrate 230, i.e., the Z direction. In this structure, only a through groove structure for the substrate 230 to pass through needs to be provided on the carrier plate 110, and the substrate 230 can be installed by passing through the groove structure. This requires less structural processing of the carrier plate 110, and does not need to provide a large groove to reduce the risk of communication leakage of the first heat exchange module 210 and the second heat exchange module 220 on the two sides of the carrier plate 110, thereby improving the operation stability of the heat exchange device.

[0056] Further, in the above embodiments, the relative positions of the first fins 240 and the second fins 250 to the substrate 230 can be arranged arbitrarily, as long as a plurality of first fins 240 are arranged in parallel and a plurality of second fins 250 are arranged in parallel to ensure the effective action of the wind power device. Therefore, in some specific embodiments of the present application, as shown in FIG. 5, one end of the first fin 240 is connected to the substrate 230 to maintain a stable structure, and the other end of the first fin 240 is arranged obliquely towards the direction of the first partition plate 150 or away from the center line of the substrate 230, so that a plurality of first fins 240 are arranged in the form of inclined wings.

[0057] It should be noted that in some embodiments of the present application, for the structure in which the substrate 230 is arranged perpendicularly to and passes through the carrier plate 110, as shown in FIG. 6, the first fins 240 and the second fins 250 can be arranged on one side of the substrate 230 or on both sides. According to the heat exchange working condition requirements, the corresponding arrangement mode is selected. When the heat exchange requirement is not high, the structure in which the substrate 230 has only the first fins 240 and the second fins 250 on one side is selected to reduce the operation cost of the whole structure while meeting the use.

[0058] When the cross-sectional length of the first fin 240 is limited by the structure, the obliquely arranged first fin 240 has a larger storage volume and surface area, and can store and use more phase change medium to improve the heat exchange efficiency. At the same time, the obliquely arranged structure can have a larger spacing between adjacent first fins 240, so that the airflow can be in more sufficient contact with the first fins 240 for heat exchange.

[0059] Correspondingly, the second fins 250 can be vertically arranged with the substrate 230, or can be arranged obliquely, when the second fins 250 are arranged obliquely with the substrate 230, one end of the second fins 250 is connected with the substrate 230, and the end of the second fins 250 away from the substrate 230 is arranged obliquely towards the direction of the second partition plate 160 or the direction away from the middle line of the substrate 230, so as to form a wing-shaped structure opposite to the first fins 240.

[0060] Meanwhile, it needs to be noted that, as shown in FIG. 9, when the first fins 240 and the second fins 250 are arranged on opposite sides of the substrate 230, they can also be arranged staggered to meet the installation and use requirements.

[0061] In order to further optimize the above technical solutions, as shown in FIG. 7 and FIG. 8, in some embodiments of the present application, corrugated teeth 260 are arranged between adjacent first fins 240, and the corrugated teeth 260 are preferably made of materials with good heat conduction effect, such as aluminum, copper, etc., so as to accelerate heat exchange with the surrounding air. When the fin structure is used for heat dissipation, part of the heat on the fins is taken away by the airflow provided by the wind power equipment, and 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 airflow to reduce the temperature of the fins, so as to achieve the purpose of high-speed heat exchange.

[0062] Similarly, corrugated teeth 260 can also be arranged between adjacent second fins 250 to achieve the purpose of accelerating heat exchange by increasing the specific surface area.

[0063] In addition, as shown in FIG. 10, in some embodiments of the present application, an electrical equipment is also provided, which comprises a cabinet and a safe-to-run electrical component 320 arranged in the cabinet. The electrical component 320 is a heating component, and a heat exchange device provided by any one of the embodiments described above is arranged on the casing 310 of the enclosure structure for the cabinet to perform heat exchange. Specifically, the casing 310 is provided with a mounting port 330 communicating the inside and outside of the casing 310 on one side, and the electrical component 320 is arranged inside the enclosed area of the casing 310 to be protected by the casing 310. The heat exchange device is fixedly connected to the mounting port 330 position by the support 10, and seals the mounting port 330, so that the casing 310 maintains a good sealing state. It needs to be noted that the installation of the heat exchange device is that the heat exchange device is fixedly connected with the side wall of the casing through the carrier plate 110 and the extension structure on the carrier plate 110, such as the first mounting surface 120 and the second mounting surface 130, 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 in the enclosure area of the casing 310, and the other is located outside the enclosure area of the casing 310.

[0064] Specifically, the heat exchange device has at least three installation states when installed on the electrical equipment, as shown in FIG. 11. In one state, the heat exchange device is installed in the installation port 330 and all the inner recesses are arranged in the enclosed structure of the cabinet 310. This state is suitable for electrical equipment with sufficient space for arranging the internal electrical components 320. In this state, the overall appearance of the electrical equipment is the shape structure enclosed by the cabinet 310, without protruding areas, which is easy for transportation and overall arrangement. In this state, the first heat exchange module 210 is in communication with the arrangement area of the electrical components 320 for heat absorption during the operation of the electrical components 320, and the second heat exchange module 220 is arranged in communication with the external area of the cabinet 310 for heat dissipation with the external air.

[0065] It should be noted that in the above embodiment, the first heat exchange module 210 is an evaporation module, which absorbs heat generated during the operation of the electrical components 320, and the liquid phase change medium inside the first heat exchange module 210 is vaporized. 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. In the vertical direction, the setting height of the second heat exchange module 220 is higher than that of the first heat exchange module 210, i.e., the setting height of the condensation module is higher than that of the evaporation module. The phase change medium vaporized in the evaporation module can rise to the condensation module, and the liquefied phase change medium in the condensation module can flow smoothly to the evaporation module under the action of gravity to complete the cycle.

[0066] As shown in FIG. 12, another installation form of the heat exchange device is that the heat exchange device is installed in the installation port 330 and all the outer protrusions are arranged outside the enclosed structure of the cabinet 310.
