The invention discloses a honeycomb vane radiator for a hollow shaft conductive modularized LED lamp and an LED lamp bank, and relates to the improvement on a honeycombed lamp radiator structure and a modularized LED lamp bank structure. The honeycomb vane radiator is lighter, convenient to assemble, excellent in radiating performance, and good in drainage and humidity elimination effects. An LED light source mounting surface is arranged on the bottom surface of a radiator body; and a plurality of through holes vertical to the mounting surface are formed in the radiator body, so that the radiator body has a hollow honeycombed structure. The LED lamp bank further comprises an upper connecting hollow shaft and a pair of lower connecting strips; a connecting plane is arranged at the bottom of the upper connecting hollow shaft; the LED lamp bank comprises at least two radiators; series connection surfaces of the two radiators are positioned on the same plane, and are connected through the connecting plane at the bottom of the upper connecting hollow shaft; and the lower connecting strips are arranged in a notch, and are connected onto the radiator body through a fastening piece to cause the two radiators to be connected into a whole. The radiating area is large, the radiating airflow exchange is smooth, the radiating effect is good, and consumed material is less.

The invention provides a thermal management system and method for electric vehicle batteries based on a memory alloy. The thermal management system comprises a battery box, wherein the battery box accommodates a plurality of variable heat transfer coefficient heat collection modules with the same structure, the variable heat transfer coefficient heat collection modules are sequentially arranged side by side to form a variable heat transfer coefficient heat collection unit, and the edge is connected with the inner wall of the battery box through a sliding rail; each variable heat transfer coefficient heat collection module includes two heat collection plates which are arranged side by side and have a certain spacing, the two heat collection plates are provided with a plurality of single batteries arranged side by side therebetween, the end parts of the two heat collection plates are connected through a memory alloy plate, the memory alloy plate is tightly contacted with the corresponding single batteries, the two heat collection plate are further provided with an elastic member therebetween, and the spacing between the two heat collection plate can vary with the size of the memory alloy plate. The thermal management system can automatically adjust the heat dissipation intensity according to the temperature of the battery system, and improve the temperature consistency inside thebattery system at the same time. In addition, the thermal management system is simple in structure and low in energy consumption.

The invention discloses a novel short-flow melt electrospinning instrument for an intelligent integrated 3D printing platform, including a motor support frame, a motor, an insulation isolation plate, a second insulation isolation accessory, a gear, a FDM printing wire reel, and an electrostatic field box body, the invention uses 3D printing based on the principle of fusion deposition, the short-flow hot-melt extrusion head system is simple in construction and operation, low in cost, safe in system operation, and simple in post-processing. By applying high voltage, the obtained fibers have micro Compared with the existing electrospinning, the raw material of the present invention is a general-purpose 3D printing consumable. By adopting 3D printing, it is intelligently integrated with the self-assembled electrostatic field, and the shape of the formed fiber is controllable, and the air circulation is carried out. At the same time, the exhaust fan and the intake fan work at the same time to realize the heat dissipation of the box. After the air entering is settled and dried, it will not affect the material processing in the box, which can better ensure the quality of the material.
