  • the second heat exchange module 220 is composed of a plurality of parallel second fins 250.
  • the first fins 240 and the second fins 250 have a connected flow channel so that the phase change medium can move smoothly within the first fins 240 and the second fins 250 to transfer heat.
  • the advantage of placing the first fin 240 and the second fin 250 separately in the first cavity and the second cavity is that they can be maintained and adjusted individually. At the same time, the fins in a single cavity remain in a parallel state, which allows the outlet angle of the wind power equipment to be adjusted when the wind power equipment is installed, so that the wind power equipment can be adapted to the fin angle in the corresponding cavity.
  • the heat exchange of the first fin 240 and the second fin 250 occurs in two relatively independent cavities. Therefore, the first fin 240 and the second fin 250 only need to remain in a connected state to satisfy the movement of the phase change medium, and their structure can be arbitrarily set.
  • 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 interchanged, and there is no need to consider the orientation during installation.
  • the normals of the first fin 240 and the second fin 250 are arranged perpendicular to each other.

  • the first fin 240 and the second fin 250 have different shapes, which can be adapted to wind power equipment with different orientations during installation.
  • the heat exchange device in this embodiment can meet its use.
  • the first fin 240 and the second fin 250 need to have a connected flow channel to meet the transfer of the phase change medium between the two heat exchange modules. Therefore, in some embodiments of this application, the first fin 240 and the second fin 250 are connected in a one-to-one correspondence. At the same time, the integrated first fin 240 and the second fin 250 are connected through the substrate 230. That is, in this embodiment, the substrate 230 is only used as a supporting structure and not as a flow channel for the phase change medium.
  • the one-to-one correspondence connection specifically means that a single first fin 240 and a single second fin 250 are connected and combined into an integrated structure, which is connected through the substrate 230.
  • the substrate 230 is set as a plate structure that supports the first fin 240 and the second fin 250.
  • the phase change medium between a single first fin 240 and the second fin 250 will not move to another position, and the filling amount of the phase change medium in each first fin 240 and the second fin 250 is uniform, and the corresponding heat dissipation effect is also more uniform.
  • the substrate 230 is a hollow accommodating structure, and the first fin 240 and the second fin 250 are both connected to the hollow cavity of the substrate 230. That is, the first fin 240 and the second fin 250 use the hollow cavity of the substrate 230 as a transfer channel for the phase change medium to complete the heat exchange and movement of the phase change medium.
  • the heat dissipation device 20 can fill a larger amount of phase change medium and has a larger single heat exchange threshold.
  • the substrate 230 and the support plate 110 are arranged in parallel.
  • the support plate 110 has a reserved embedding space for the substrate 230, allowing the substrate 230 to be completely sealed and embedded within the support plate 110, forming an integral structure with the support plate 110.
  • the support plate 110 and the substrate 230 may be a single plate structure, possessing both separation and support functions.
  • the first heat exchange module 210 separated by the support plate 110, consists entirely of the first fins 240 on one side of the substrate 230
  • the second heat exchange module 220 also separated by the support plate 110, consists entirely of the second fins 250 on one side of the substrate 230.
  • This structure maintains the sealed state of the support plate 110 after the substrate 230 is installed, preventing air leakage between the cavities of the first heat exchange module 210 and the second heat exchange module 220.
  • the substrate 230 is disposed perpendicular to the support plate 110 and passes through the support plate 110.
  • the first fin 240 and the second fin 250 are disposed on both sides of the support plate 110.
  • One side of the substrate 230 has a portion of the first fin 240 and a portion of the second fin 250.
  • the first fin 240 and the second fin 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 opened on the support plate 110 to complete the through installation of the substrate 230.
  • the structural processing requirements of the support plate 110 are small, and the absence of a large groove reduces the risk of communication leakage between the first heat exchange module 210 and the second heat exchange module 220 on both sides of the support plate 110, thereby improving the operational stability of the heat exchange device.
  • the relative positions of the first fin 240 and the second fin 250 with the substrate 230 can be arbitrarily set, as long as several first fins 240 and several second fins 250 are arranged in parallel to ensure the effective function of the wind power equipment after installation. Therefore, in some specific embodiments of the application, as shown in FIG5, one end of the first fin 240 is connected to the substrate 230 to maintain a stable structure, and the end of the first fin 240 away from the substrate 230 is inclined towards the direction of the first partition 150 or away from the centerline of the substrate 230, so that several first fins 240 are arranged in an inclined airfoil structure.
  • the first fin 240 and the second fin 250 can be provided on one side of the substrate 230 or on both sides.
  • the corresponding setting method can be selected according to the heat exchange requirements. When the heat exchange requirements are not high, a structure in which the first fin 240 and the second fin 250 are only on one side of the substrate 230 can be selected, so as to reduce the overall operating cost of the structure while meeting the use requirements.
  • the inclined first fin 240 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, which enables more phase change medium to be stored and used, thus improving heat exchange efficiency. At the same time, the inclined structure can provide a larger gap between adjacent first fins 240, allowing the airflow to make more sufficient contact with the first fins 240 for heat exchange.
  • the second fin 250 can be arranged perpendicularly to the substrate 230 or inclined.
  • the second fin 250 is inclined to the substrate 230, one end of the second fin 250 is connected to the substrate 230, and the end of the second fin 250 away from the substrate 230 is inclined toward the second partition 160 or away from the centerline of the substrate 230 to form an airfoil structure opposite to that of the first fin 240.
  • first fin 240 and the second fin 250 when the first fin 240 and the second fin 250 are disposed on opposite sides of the substrate 230, they can also be staggered to meet the requirements of position installation and use.
  • corrugated teeth 260 are provided between adjacent first fins 240.
  • the corrugated teeth 260 are preferably made of materials with good thermal conductivity, such as aluminum or copper, to accelerate heat exchange with the surrounding air.
  • the corrugated teeth 260 have a large specific surface area, which can quickly exchange heat under the blowing of airflow and reduce the temperature of the fins, thereby achieving the purpose of high-speed heat exchange.
  • corrugated teeth 260 can be provided on the adjacent second fin 250 to accelerate heat exchange by increasing the specific surface area.
  • an electrical device is also provided.
  • This electrical device includes a housing and an electrical component 320 for safe operation disposed within the housing.
