The invention discloses an efficient heat radiation device for a lithium ion power battery. The device comprises a thermal-arrest panel which can tightly fit with the battery, a U-shaped heat pipe filled with a working fluid and a radiating fin group. A bent part in the middle of the U-shaped heat pipe is embedded in the thermal-arrest panel, and overhanging parts at two ends of the U-shaped heat pipe extend out of the thermal-arrest panel. The radiating fin group is tightly secured to the overhanging parts of the U-shaped heat pipe through holes. By the device, efficient heat radiation of the lithium ion battery can be realized, and temperature uniformity between single batteries of a battery pack is raised. Thus, usability of the battery pack is raised, the thermorunaway risk is reduced, and service life of the battery pack is prolonged. A phase-change heat-transfer element heat pipe with high heat transfer coefficient is adopted. The phase-change heat-transfer element heat pip has good heat storage and heat radiation properties and has high operation reliability. Meanwhile, the device provided by the invention has advantages of simple structure and low cost, and is energy-saving and environmentally friendly.

The invention discloses an air cooling heat dissipation mechanism for a wheel hub motor of an electromobile. The air cooling heat dissipation mechanism comprises a wheel hub motor outer shell and a motor winding, and at least two vanes which protrude outwards are distributed on the circumference of the outer surface of one side of the wheel hub motor outer shell in an equidistant mode. Heat generated in the operation process of the wheel hub motor can be quickly scattered by the mechanism, the defects that operation can not be normally conducted due to too high temperatures caused by overload work such as increasing of the power of the wheel hub motor and increasing of torque are overcome, and the safety in the traveling process of the electromobile is guaranteed.

The invention provides a data migration method and device, a storage medium and a program product, and the method comprises the steps: exporting data of an original database table to be exported in an original database to obtain a first file; determining a migration strategy according to capacity information and/or system performance information of the database table, and importing data in the first file into a target database according to the migration strategy to form a target database table; exporting data of the target database table of the target database to obtain a second file; and comparing the content of the second file with the content of the first file, and if the content of the second file is consistent with that of the first file, determining that data migration succeeds. By means of the process, mass data migration, inspection and checking can be completed in a one-button mode. According to the method and the device, the optimal export and import strategy can be selected according to the database table capacity and/or the system performance, efficient and accurate export and import of the data are achieved, manual participation is reduced, in addition, full-amount comparison of the data is achieved based on file comparison, and the accuracy of mass data migration is guaranteed.

The invention discloses an LED (light-emitting diode) tube core with a ZnO-micron and nano composite structure and a preparation method of the composite structure. The LED tube core is prepared in a way that a ZnO-micron graphic array grows on a luminous surface of the LED tube core and a nano rod vertically grows on the ZnO-micron graphic array.; The preparation method comprises the following steps: (1) planting an LED epitaxial wafer and preparing the LED tube core with a complete structure; (2) sputtering a layer of ZnO seed layer on the LED luminous surface; (3) preparing a photoresist micron periodic pattern on the LED surface; (4) taking the photoresist micron periodic pattern as a template to grow the ZnO-micron graphic array; (5) removing photoresist by glue removing liquid to obtain the ZnO-micron graphic array; (6) sputtering a layer of ZnO seed layer on the ZnO-micron graphic array, and (7) growing a ZnO nano rod array on the ZnO-micron graphic array. According to the invention, not only can the emitted light be extracted at higher ratio, but also the uniformity of light emitted from the entire light emitting surface of the light emitting diode is guaranteed.
