The invention discloses a safe and energy-saving lithium battery pack dual-mode thermal management system and method, and the system comprises one or more layers of batteries and / or battery modules ina battery pack, a battery pack housing, a liquid cooling plate-tube heat exchanger, and an external air cooling module, the internal of the external air cooling module is provided with air cooling fins, and the side surface of the external air cooling module is provided with a fan; a micro heat pipe array is attached to the upper surface and / or the lower surface of the battery and / or the batterymodule, the part attached to the surface of the battery and / or the battery module is an evaporation section, and at least one end of the micro heat pipe array extends out of the surface of the batteryand / or the battery module to serve as a condensation section to be attached to a battery pack shell. The battery pack shell is at least provided with a heat conduction partition plate at the positioncorresponding to the condensation section; the liquid cooling plate-tube heat exchanger is at least correspondingly attached to the outer surface of the heat conduction partition plate and connectedwith a refrigerating system outside the battery pack, and a base plate of the external air cooling module is attached to the outer side of the liquid cooling plate-tube heat exchanger. And the advantages of high heat dissipation efficiency, safety, energy conservation and the like are achieved.

The invention discloses a dry-wet separated lithium battery pack thermal management system and method. The system comprises one or more layers of batteries and / or battery modules in the battery pack,a battery pack shell and a liquid cooling plate-tube heat exchanger, wherein a micro heat pipe array is attached to the upper surface and / or the lower surface of the battery and / or the battery module,the part attached to the surface of the battery and / or the battery module is an evaporation section, at least one end of the micro heat pipe array extends out of the surface of the battery and / or thebattery module, and the extending part serves as a condensation section to be attached to a battery pack shell; the battery pack shell surrounds the battery pack and is of a closed structure, and a heat conduction partition plate is at least arranged at the position corresponding to the condensation section; a substrate of the liquid cooling plate-tube heat exchanger is sealed and is completely physically isolated from the battery and / or the battery module; and the liquid cooling plate-tube heat exchanger is at least correspondingly attached to the outer surface of the heat conducting partition plate and is connected with a refrigerating system outside the battery pack. The system has the advantages of high heat dissipation efficiency, dry-wet separation and liquid leakage prevention.

The invention discloses a lamp, which comprises a casing and a rotating mechanism arranged outside the casing; the rotating mechanism includes a fixing piece, a bracket, screws and nuts. The fixing part is columnar and fixed on the outer wall of the housing; there is no need to open holes on the housing, and the fixing part will not affect the sealing and waterproof performance of the housing, ensuring the protection level of the lamp. A card slot is provided on the peripheral surface of the fixing part, and the nut is arranged in the card slot. After the nut fails, it can be easily replaced with a new nut. A connection hole is opened on the end surface of the fixing piece; the bracket includes a first support plate and a second support plate fixedly connected, and a through hole is arranged on the second support plate, and the screw passes through the through hole and the connection hole and is threadedly connected with the nut in turn; the shell The body and the fixing part rotate with the screw as the rotating shaft, so as to adjust the light emitting angle and realize the rotation function of the lamp. A limiting protrusion is provided on the peripheral surface of the fixing member, and a limiting member is provided on the first support plate. Through the cooperation of the limiting protrusion and the limiting member, it is possible to prevent the housing from turning 360 degrees and breaking the incoming wire of the lamp.

The invention provides a distribution box which is convenient for removing foreign matters, and relates to a distribution box. It solves the problem of removing foreign objects in the distribution box in the prior art. The distribution box for easy removal of foreign matter includes a box body, a sewage discharge hole is arranged on the bottom plate of the box body, and a cover plate is arranged on the sewage discharge hole, and the edge of the cover plate is connected to the sewage discharge hole through a rivet rotation. edge of the hole, the cover plate is located inside the box. The invention can open the hole by setting the rotating cover plate, and the foreign matter can fall from the hole, which not only ensures the protection level of the distribution box, but also can remove the foreign matter conveniently. Another type of distribution box can realize the discharge of sundries at the bottom of the box without opening the box. The structure is simple, the operation is convenient, the cost is low, and the efficiency can be greatly improved.
